These studies will have to culminate in a description of the nature of the remedies we have arrived at and which we then need to bring into more common use. But it will not be possible to speak properly about what one must know and master with regard to these remedies if we have not fully prepared ourselves. This must be done first. Therefore today we will study a few of those things that can guide us into the whole web of man's being, which results from the cooperation between ego, astral body, etheric body, and physical body. I have already mentioned that, by means of a certain effect of arsenic, one can drive the astral body further into the organs than is otherwise the case in the human being. Of course, the astral body draws the ego in with it.

By driving the astral body further into the organs, we enhance the mineralizing process in the organs. And if we notice that the organs are indicating a proliferating etheric, are too active vitally, developing life forces that are too strong, then the introduction of arsenic would have a healing effect. One can even designate something that occurs inside the human being by means of an outer process that has a certain affinity with the human process. If you want to express this affinity of the astral body with the etheric body—and thereby with the physical—you may speak of “arsenizing.” A gentle “arsenizing” is continually taking place in the human being and is especially strong at the moment of waking. We must realize clearly that the human organism has within itself, as a system of forces, that which lies in the metals. This affinity between the human being and his earthly-cosmic environment is certainly present; certain processes that unfold outside and come to an end in the metals, for example, also occur in the human being. Hence, when we speak of “arsenizing” the human being, you must not think of the arsenic as directly active; rather the human being is itself active within in the way that arsenic is active outside.

Through this one attains insight into the way to assist such effects in the human being. When you study this “arsenizing” process—I might also say this “astralizing” process—in the human organism, you will notice that when it is too active it finds expression in a kind of warming in the region of the stomach, whereby digestion and assimilation become facilitated. When these become excessively facilitated, it can become a serious problem, because difficulties then arise as reactions to such processes that occur with too great a facility. All this is connected with a certain mineralizing process in the human being. This is a direction to pursue in our research. But such research must be done in the right way, taking all the other factors into consideration. The bodies of people who “astralize” too strongly, i.e., “arsenize” strongly in their organic physical processes, do not decompose so readily as those of people whose astral bodies are weakly connected with their organs. This is certainly something that ought to be observed. Indeed, one sees the extreme form of this tendency in bodies poisoned by arsenic; they tend to mummify and do not decompose easily.

Now the question is: What can we do if this “arsenizing” (or “astralizing”) process is too strong, that is when the person mummifies himself while alive, so to speak? One must have an eye for such things. If a person is mummifying too intensely, how can we counter this process? If I may express myself radically, I would say that then one must make the whole human being partly into a tooth. This is something that can give us many clues into the mysterious working of the human organism. One must make the whole human being into a tooth. In some way or other one must try to give him the radiating force of magnesium, taking the whole organism into account. He must be given some preparation of magnesium, thus introducing into his whole organism the radiating force of magnesium, which Professor Römer has described. This is something that leads us deeply into the relation between the astral body (which is also carrying the ego) on the one hand and the etheric and physical bodies on the other.

Let us now consider the opposite condition in the human being, in which the astral body and the ego have an inadequate tendency to permeate the organs. The organs, in so far as they are nurtured by the physical and etheric influences, begin to be left to themselves. The expression of this condition is that there is no proper connection between things that should work reciprocally, between the reciprocal nourishment of the human being by his environment and the inner organic processes. The inner organic processes begin to develop their vital forces too strongly. They receive no influence from outside; the permeation of the food-substance by the forces of the ego diminishes. The astral body, in consequence, has to be too active in one direction and cannot reach the etheric body properly. A proliferation of physical and etheric activity occurs, expressing itself in diarrhea, which is essentially connected with such phenomena. Blood is found in the stool, and the inner vital activity becomes so strong that small, organic tissues peel off from the intestinal walls. These are also found in the stool, which takes on the appearance of a fluid resembling beef bouillon. Finally protein is drawn into the process and excreted without being worked through in the proper way. Such phenomena clearly indicate that the vital force is proliferating, unhindered by the “astralizing” force.

The astral body and the ego must work into the physical and etheric human being if these half-conscious movements of the digestive tract, that are necessary for the organism, are to occur. Now imagine that the astral body and the ego are not inserted in the right way and that the etheric body and the physical body remain active by themselves. There then arises a nervous need to relieve the bowels, which is characteristic of such conditions. The farther you follow this matter, the farther you are from ordinary diarrhea and the nearer to dysentery. The farther you proceed with the description of this clinical picture, the more you find yourself describing in all these phenomena the opposite of “arsenization,” or “astralization.” And as the astral body is strongly implicated in all this, you will be led, by the matter itself, to the conclusion that the antidote to be used is in everything that comes from arsenic, i.e., that one must oppose these conditions by “arsenizing.”

I believe that we can deeply enrich and intensify our ideas in relation to such things if we make clear to ourselves that there are processes in the outer world corresponding to everything that takes place in the human being. And even if it must sound dreadful to one who has passed through the educational system of today, I do not want to avoid using certain expressions that have a serious meaning for spiritual science and which, if understood correctly, can lead us very deeply into these matters.

You see, the “arsenizing” (or “astralizing”) process observed in the human being, the mummification of the physical organism, its becoming brittle, is basically the same process as that which takes place when the earth forms rocks. Wherever rocks are in process of formation the earth is, in a sense, poisoned by arsenic or in the early stages of poisoning. Imagine, on the other hand, that the outer astrality that surrounds the earth everywhere (as I suggested in the last course of lectures), succeeds in avoiding the surface of the earth and rests directly on the water. Imagine that it avoids playing its part in bringing forth the blossoms, the growth and the emergence of the plants from the earth into the atmosphere. The outer astrality penetrates below the ground, and in these areas the earth gets dysentery. The process I am now describing ought to be taken into account, for there is much that is real behind it. It should be considered, because it gives information as to the connection of what takes place under the earth with a phenomenon such as dysentery, for example. In dysentery, we observe an effect on the human being of what lies under the ground, particularly in water, and it must be studied from this viewpoint. The essential thing to consider is that the astral body is very much involved in the matter, and hence to cure it it will be necessary to use intermediate potencies, because the efficacy of the astral body is through the middle system in the human organism.

Now phenomena such as those that take their course like diphtheria are especially able to teach us about certain subtleties in the human organism. Such diseases should be studied more precisely, if only for the sake of discovering remedies. I believe the opinion that has arisen from materialistic conceptions is still held that diphtheria must be treated locally as much as possible. Of course, numerous opposing opinions have also been expressed regarding this. The significance of the emergence of diphtheria—and to everything related to it—leads us to make some additions to what we studied in the last course, because at that time we were not yet able to deal so precisely with this interaction of the four members of the human organism.

In another context I have indicated that the child's acquisition of speech is accompanied by various organic processes. While he is learning to speak, and therefore while something special is taking place in his breathing organism, something also occurs polarically in his circulatory organism, which also receives into itself the metabolic processes. I also pointed out, in yet another context, how what at puberty appears in a reciprocal relationship of the human being to the outer world, takes place inwardly in learning to speak. Thus this push of the astral body, which at puberty takes place from within the human being outward, takes place from below upward in the astralizing process. The capacity for acquiring speech also develops from below upward. So here too we have an astralizing process, and we will be able to see clearly that an interaction occurs where the respiratory and circulatory systems meet (see drawing). The astralizing process working from below upward (yellow) encounters the developing organs of speech working from above downwards (red). In this encounter the organs of speech become stronger in their capacity for speech. It is what is taking place simultaneously below that especially interests us here: this tends to work upward. The whole process is one from below upward (yellow arrows). Now, if the astrality presses upward too strongly while the child is learning to speak, we have a predisposition to diphtheric conditions. It is certainly important to pay proper attention to this.

Let us now consider the outer earthly process that has a certain selective affinity for the process I have just described. Let this be the surface of the earth (see drawing above). In a plant that behaves appropriately in relation to the cosmos, the earth plays a part in the formation of its roots. With growth the influence of the earth diminishes and the extra-terrestrial influence becomes stronger and stronger, unfolding especially in the blossoms (see drawing, red). What develops here is a kind of external astralizing of the blossom, which then leads to the formation of fruit. If this process, which ought to occur in the normal course of the world processes, takes place below (see drawing below), it can only insert itself into the water, and we have what I have just called “dysentery of the earth.”

But we can also have another situation: What takes place when a plant develops properly—the blossom unfolding always a little above the earth's surface—can develop right on the earth's surface (see drawing below, red). Then fungi arise; this is the basis for fungus formation.

And now you will begin to guess that, if fungi arise from such a special astralizing process, the same process must take place from below upward when, as in diphtheria, this remarkable astralization occurs in the human head. This is actually the case. Hence you find in diphtheria the tendency to fungoid formations. It is most important to consider this tendency to fungoid formations in diphtheria, and it will also show you that a truly occult process is taking place there. Everything external is really only a sign that irregular astral currents are prevailing within the human being. This will suggest to you how a pathology, willing to consider merely outer symptoms, can know only the outer manifestations of the whole process; it then regards this process as local, for it sees only the outer aspects and does not consider what is pushing from within outward in such cases. The whole skeptical attitude adopted toward this process is certainly explicable if we trace it back to what we have just discussed.

As a matter of fact, the risk of infection in diphtheric conditions is very great. Why is it so great? Because diphtheric conditions clearly arise in connection with the acquisition of speech. Because of this they occur primarily in children from age two to four. Later the risk is very much less. However, every process that occurs as the normal course of events in the human organism at some time or other can also arise abnormally. Thus, this process, which is simply a concomitant of childhood, can also occur at another period of life, although somewhat modified or metamorphosed. Nevertheless, when a type of diphtheria occurs at a later stage in life, there is something of an infantile nature at work in the individual. The fundamental characteristic of the infantile stage is, as you know, the tendency to imitate. When expressing the facts of spiritual science about infants, it is only necessary to speak of the more psychological aspect, the external manifestation of the childhood stage is certainly this imitative aspect. The organism itself is forced to become imitative when it becomes diphtheric. Infection is due to a person becoming an imitator. Indeed, there is a very delicate sensitivity involved in this imitating. When this condition is studied with the methods of spiritual science, one finds that the ego actually plays a certain role in infection with diphtheria. For this reason, the parasitic aspect, what develops as fungoid growths, is more infectious than in other diseases. This is because the human organism, by virtue of its imitative tendency, comes to meet the trouble, adjusting itself in an imitative, receptive way as soon as it “perceives” the diphtheric poison. Hence a psychological rebuke, when it is possible in the initial stages, and psychological support by encouragement may well have a favorable effect.

But when, as here, the processes work so deeply into the organism, much more will naturally be achieved by trying to find the specific remedy with which to oppose the particular process at work. I am not aware of whether any steps have been taken to find, even empirically, a specific remedy for diphtheric conditions. One should try intermediate potencies of cinnabar. In cinnabar we will find effects that counteract all the phenomena I have mentioned. Cinnabar expresses this even in its outer appearance. The outer appearance of substances, however, is only of use when we supplement it with inner perception. The old “Doctrine of Signatures” was based on an instinctive, inner perception, and it has perished because people today no longer have the capacity to observe such things. Nonetheless it is important to be able to study these inner activities manifesting in all external appearances in the world. We ought not become involved in all sorts of mystical notions; if instead we acquire a sound understanding of such things we will recognize that cinnabar through its vermilion color is something that in a certain way brings to expression this activity opposed to the fungoid process. That which is approaching the colorless can become fungoid. While too strong an astralization of the earth's surface plays a part in the formation of fungi, in cinnabar there is a counter-reaction to this astralization and thus this reddening. Wherever a reddening appears in natural processes, we find a powerful counter-effect to the astralization process. You could express this in a moral formula: “The rose in blushing works against astralization.” These domains of pathological-therapeutic study are really interconnected in a certain way. They guide us into this peculiar relationship of the ego and astral body to the other organs, to their laying hold of organs, to their emancipation from organs, or to manifestations of the excessive working of the astral from below upward.

In this way insight can gradually be gained into the whole human body. This can be understood more thoroughly if one takes these studies to a further stage. Here you will have to take into account something that I would like to add now to what I presented to you last year. It is remarkable that the human ego, studied in its spiritual, psychical, organic, and mineral activities, is a kind of vehicle, you could say, for phosphorus. The ego creates the phosphorus-vehicle in such a way that with this vehicle it extends to the periphery of the organic human being. The phosphorization of the human organism is an activity of the ego. Through the ego, this phosphorus distribution is extended to the outermost borders, to the very periphery of the organic human being, in a most ingenious way. To a certain limit—which must not be exceeded, however—the ego can only carry phosphorus through the organism by first combining it chemically to other substances. The ego in essence hinders the chemical liberation of phosphorus by carrying it through the organism. This is one of the ego's tasks, to hinder the chemical liberation of phosphorus, of all but the traces of phosphorus required by a certain special process. This process would occur on a large scale if the ego did not succeed in preventing the liberation of the phosphorus taken in.

If the phosphorus were to be set free, inducing an intensive effect in the human organism, there would be definite consequences. I have told you in the course of these lectures that when the human being enters the world, that is, when his pre-existing soul-spiritual aspect comes into corporeality, the imprints of the etheric body, astral body, and ego are first created. I also said to you that everything constituting the imprint of the ego is actually to be found in dynamic systems, the systems of movement that are brought to an equilibrium. This is something to which we must pay special attention at this point in our considerations.

The ego requires phosphorus to bring about equilibrium between unbalanced states or those in which the balance has been disrupted. When I take a step forward, my equilibrium is disturbed and I must restore it again, but through the help of inner processes. This task in the human organism is accomplished essentially with the help of phosphorus. When the ego does not exhaust its phosphorizing activity in making static what is dynamic within the human being, it brings phosphorus to the imprint of the ego already present, to this process of making static what is dynamic. I have frequently drawn your attention to the fact that in addition to our solid constituents we must also consider the fluid man, the aeriform man, and the warmth man. Picture to yourselves the fluid man, that which is expressed in the imprinting of the ego, of the astral body, and then the ego itself, in the etheric body. This means that in the etheric body something dynamic, something not in a state of equilibrium, must continually be brought into equilibrium.

What we are speaking about here has to do with extraordinarily delicate effects. And these delicate effects are regulated by the presence in the human body of free-floating globules that are nevertheless connected with the whole movement of the organism, including the inner movement. These are the blood corpuscles. Against these blood corpuscles must beat the activity of the ego within the body's mobility—including, for example, the mobility of warmth. These blood corpuscles are not really little globules but are essentially constituted so that even their form shows that they are intended to guide movement over into equilibrium. What the ego does in working into the capacity for movement of the human organism reaches its limit at the blood corpuscles. Here it has to stop, and that most intimate interaction between the human ego and the whole human organism must occur. Here too occurs what I might call the most hidden battle between the continual phosphorizing process in the human being and the formative process of the blood. Thus, if phosphorus is brought into the human being in the free state, the blood corpuscles are destroyed by the phosphorizing process.

This is something that can lead us pictorially to this remarkable reciprocal action of the ego, which is a spiritual entity. Indeed, the ego is spiritual through and through, but it continually interacts with the physical through the blood corpuscles. In this respect, “blood is a very special fluid,” as an old saying—not Goethe—tells us. For in the blood the outer physical part of the human being interacts with his most spiritual member, the first that he carries with him, the ego. It is in the blood that the most injurious processes can arise when the ego enters into this interaction improperly. A great deal in the physical body can be ruined by such an incorrect interaction: destruction of the epithelium, fatty degeneration extending to the muscle fibers—especially the striated muscle fibers, for the ego acts especially on these—disintegration of the blood corpuscles, and so on. Indeed, this corporeal process of degeneration can extend into the bones if the phosphoric effects are not in order.

This interplay between the ego (which, of course draws the astral body with it) and the physical body (which then draws the etheric body with it), shows us clearly that there is a constant striving toward a normal and an abnormal state. The normalizing tendency attains a certain culmination and is then followed by a decline. We see this manifested when we have to do with a case of poisoning by phosphorus, for instance. In phosphorus poisoning, you will find that in the first place the astral body and the etheric body resist what is occurring in the physical body and the ego. They resist, they defend themselves with all the force, with the strongest force, of the etheric body. The etheric body tries to stand up to the over-activity of the ego; it tries to counter this by strengthening its own forces. Therefore there is an inner similarity between the process of the first stage of poisoning by phosphorus and another process, namely, the occurence of the review of life after death. As you know, this can last for a day and a half, or for two to three days. During this review the etheric body is held within the astral body. In a sense, they cling together. This also happens in the human body when phosphorus poisoning occurs. Everything that can develop through the cooperation of the astral and etheric bodies, which takes place during this review after death by means of the etheric body, is developed now. Hence through these forces that are expended in the first stage of phosphorus poisoning, an improvement will set in after a lapse of as long a time as such a review would last. There will be a kind of fatiguing or recession, and then after this recession the abnormal influence of the ego will set in with even greater intensity. An actual case of phosphorus poisoning is extraordinarily difficult to treat, because it can only be combatted by trying to find a way of inducing in the whole organism an intense cooperation of the astral with the etheric. This could be achieved by opposing the phosphorus poison with a strong application of drawing plasters applied to various parts of the body. You would certainly achieve results in this way. Of course something must be known about these things, and one has to have a feeling for how far to go.

Thus the physical organism, when the ego intervenes in it, can be intensely engaged by being involved in what we may call “phosphorization” of the human being. However, when the ego intervenes strongly in the physical organism,—that is, in a destructive way—the polar opposite must necessarily occur: what the ego normally does in the human organism, when it does not intervene too strongly, must suffer. Hence you will find a phosphorization that is too powerful accompanied by states of insomnia, due simply to an excessive proclivity of the astral body and ego to the physical. You could deduce this from everything I have said. You will find headaches and all the conditions usually accompanying paralysis. These conditions naturally arise in connection with what I have said about the interaction with the blood. What lies in the middle, and what therefore appears with phosphorization (when the ego attacks the blood corpuscles and is repelled again in the alternating process described) comes to expression in conditions of jaundice. In fact, in jaundice we can also observe an interplay of the psychological and the physical.

From what I have presented to you, you will see that the process constituting the human being is essentially a cooperation of the ego and astral body with the forces of the outer world, within the space enclosed by the skin. It is a process working in from without, and one must be able to study correctly how this process can be regulated, how one can acquire a kind of control over it.

Certain dietetic measures that would be effective occur to one when studying ailments with this perception as a foundation. If the ego is working too strongly in the human being, causing irregularities in the stomach, but at the same time an overvitalization is at work in abnormal diarrheal conditions and the like, it is necessary to combat this by appropriate dietetic measures. The actual ego process and the process of the astral in the human being are a kind of analyzing process; they fragment what is synthetically present in the outer world. Whereas we have a kind of primary synthetic process in the physical and etheric bases of the human organism, we have an analytic process in the ego and astral activities. This analytic process is a part of the normal activities of the human being, and its unusual character is expressed strongly in the necessity of keeping it within bounds. If the ego becomes too active an analyst regarding phosphoric salts, it decomposes them as far as the phosporus, and this then begins to be unhealthy for the human organism. In last year's lectures I referred to this analyzing process carried as far as iron: this is the farthest point to which analysis can be carried without harm. This process of analysis carried as far as iron is connected with the iron content of the blood. In many respects this is the polar opposite of analysis with respect to other metals, where the analytical process must, in a certain sense, be restrained.

Today I wanted to show you how outer phenomena in fact give us pictures of what is developing from the inner spiritual aspect. On this account the outer view of the human being in states of health and illness must be supplemented by what one can learn of the inner, of the spiritual human being. We now have a basis for understanding our remedies and answering many of the questions that have been asked.

We will deal with these as much as possible in the remaining lectures.

I said yesterday that these studies are intended to lead us on to a clarification of the essential nature of the remedies we have proposed, and we will continue to pursue this theme. Today I would like to begin by mentioning something that can suggest a great deal regarding our method of working.

In approaching an illness or a complex of symptoms with imaginative observation, we frequently receive a direct, intuitive knowledge of the remedy. Then we obviously attempt to think about the matter in accordance with judgments connected with the matter by external scientific knowledge, and we find we are wrong, that it cannot be so. This is an experience frequently encountered by one who is able to make occult investigations, and it also applies to domains other than therapeutics. Only on thinking more about the matter, pursuing it still further, does one come to see how correct one actually was. What is discovered by imaginative investigation followed by intuition is always correct, provided, of course, that it is based on sound powers of cognition. But one's judgment activity must first wrestle through—if I may put it so—to what one comes to know in this way.

It must first be realized that this human organism is complicated to the highest degree, so that in fact an intellectual grasp of it presents the greatest conceivable difficulties, especially if one tries to relate this human organism to the outer world again. This is especially noticeable if we examine more closely the function of nitrogen in the human organism. Earlier in these lectures, I reported that nitrogen is found in greater quantity in exhaled air than in inhaled air and materialistic thinking can hardly help regarding the difference as unimportant. The reason for this is that the materialistic view of the human being is basically unable to discover the function of nitrogen. This is possible only if the following is considered:

You know that the most varied theories exist about nutrition and that, accordingly, investigators often hold diametrically opposed views regarding the question: ”What is the function in the human organism of protein in food? Why does the human organism need protein?” Some say that the structure of man's protein organism is constant, or at least relatively constant, and that the protein absorbed undergoes rapid disintegration and has little significance for the plastic, constructive forces of protein in the human organism. Others hold the view—regarded somewhat out of date today—that the proteinaceous body of the human being is continually disintegrating and built up again from the protein absorbed. These diametrically opposed theories are put forward in the most varied forms, but both miss the essential point, because they compare protein with protein in a one-sided way without considering the human organism as a whole.

In this human organism we have to do with an opposition between the head formation, and therefore the formation of nerves and senses, and the formation proceeding from the metabolic-limb system. This is a polar opposition within human nature, and we cannot pay enough attention to it. Without taking into account what I have just said, we cannot understand the sequence of stages in the build-up of man that are so important in therapeutic deliberations. For instance, one will not be able to understand the real relationship of the lung to the entire human organism unless one's investigations begin in the following way. If we are considering the head organism, certain forces obviously predominate there. Next we have the chest organism containing the lungs. The lung is an organ that also has forces of head formation within it, though to a lesser degree. The whole human organism has everywhere these same forces, but in varying intensities. And if we investigate how the ego, astral body, and etheric body work in the whole plastic formation and deformation of the organs, we are brought to the paradoxical statement that the lung formation is a less intensive head formation. The lung formation is a metamorphosis of the head formation, only it is arrested at an earlier stage. The head advances further with regard to the same formative forces that are present in the lung but remain there at an earlier stage.

Because the lung has remained a kind of retarded metamorphosis of the head formation it is adapted to its own function, i.e., breathing. If the same forces that remain retarded in the lung, making it suitable for breathing, develop further, they render the lung more and more head-like. A consequence of the lung becoming more and more head-like is that it takes in thought forces—the organic forces of thinking—and strives to become a thinking organ. In trying to become a thinking organ, taking up too strongly the forces properly seated in the head, the lung becomes disposed to tuberculosis.

Pulmonary tuberculosis can only be understood in this way, proceeding from the entire human being. It can certainly be understood if we realize that in a tuberculous lung breathing strives to become thinking. In the head, breathing is metamorphosed, and all functions of thinking, even the processing of perceptions, are nothing but breathing developed further in an upward direction. The head is an advanced respiratory organ, having moved beyond the lung stage, but it represses breathing and, instead of taking in air, takes in etheric forces through the senses. Sense perception is nothing but a more refined—which means extending more into the etheric—respiratory process. Thus head and lung breathe. There is something else in the human being that is also breathing, something that remains at a still lower stage in this process of metamorphosis: the liver. The liver is a lung that has not reached its final development, it is a head formation not fully developed. It also breathes, but now the other metamorphosis, the polar metamorphosis of the sense perceptions—that is, taking in food and working it through—predominates in the liver. Therefore lung and liver formations lie in the middle between the stomach and the brain and head formations.

If you lay a foundation with such thoughts, you will not be far from understanding what I have to say about certain human organs really being organs of respiration. All those organs that are shaped like the brain, lung, and liver are at the same time organs of respiration, but they have a tendency to breathe out. Thus they also excrete carbon dioxide externally. Such external excretion of carbon dioxide is the essential thing in breathing. These organs absorb oxygen and give off carbon dioxide, and this holds good not only for the lung but for the entire organism, for every organ. It is essentially an activity of the astral body, which develops its activity in sympathy and antipathy. Sympathy as a force corresponds to inhalation; antipathy as a force corresponds to exhalation of the astral body. In the description of the astral body given in my book, Theosophy, you find that it is permeated by the forces of antipathy and sympathy. It works in the human being in the whole breathing process according to antipathy and sympathy. This must be regarded as the inner activity of the astral body.

And now we come to the final point of these considerations. The proteinaceous content present in the human being, in so far as it belongs to the organs described, is essentially for the support of breathing and manifests outwardly through breathing. But everything that manifests outwardly also expresses itself inwardly. This is how I would sketch it schematically. If you have here a human organ rich in protein and belonging to the group of organs I mentioned, it manifests outwardly by developing the activity of breathing (see drawing, red). But in breathing outward, it unfolds another activity within, the polar activity to breathing, namely, the activity liberating the soul, liberating the spirit. An activity freeing the soul: in breathing out, in unfolding the act of breathing in an outward direction, you unfold inwardly a soul-spiritual activity. This does not require space, of course; on the contrary, in space it disappears continually, passing out of three-dimensional space. This activity manifests within, however—in an inward direction—and to develop this activity within is essentially the function of human protein. What functions as an activity in the head enters from outside by way of the senses. Hence the head organs are the organs containing least of what is spiritual. They absorb the spirit from outside, acquiring it for themselves by means of the senses. The head is the least spiritual organ in the human being.

By contrast, man's spirituality—that is, the development of spirit within, the development of spirituality in the body, of real spirit, not abstract spirit—begins in the pulmonary system and works from outside inward in contrast to breathing. The most spiritual organs are those belonging to the liver system. These are the organs that develop the most spiritual activity in an inward direction. This also explains why “head men” are often materialistic, because only the external spirituality can be worked through with the head, and in this way one is wrongly led to believe that everything spiritual that is developed is received from outside, from the world of the senses. If a person is a real intellectual, then he becomes at the same time a materialist. The more one is a “head thinker,” the more one is disposed to become a materialist. On the other hand, if the whole human being struggles to attain knowledge, if a person begins to develop a consciousness of the way the entire human being thinks, including the organs situated further back, materialism ceases to be justifiable.

The activity manifesting in breathing is also revealed outwardly in the excretion of carbon in carbon dioxide. But the inward activity of spiritualization is bound up with nitrogen. The nitrogen that has been used in spiritualization is eliminated, and the degree to which nitrogen is eliminated is a measure of the inner work of the human organs in the direction of spirituality. You can conclude from this that one who does not believe in such spirituality will obviously have to remain very unclear about the absorption of nitrogen in the human organism. The role played by nutrition can be clarified only if one knows how in all protein formation there unfolds an activity directed outward and one directed inward. If you study this process, which is essentially a breathing process with its polar opposite, you will realize that nutrition and digestion border everywhere on the breathing processes, that nutrition and digestion everywhere encounter the processes of breathing and spiritualization.

In this process of spiritualization, and therefore on the other side of breathing, are found the real shaping, plastic forces in protein formation: there we find everything that shapes the human being. From this you will also be able to see that what is active here points to an interaction between the astral and etheric bodies. The astral body is active in breathing by means of sympathy and antipathy; the etheric body is active through encountering in its activity the sympathies and antipathies of the astral body. Everywhere the etheric body with its activities hits up against the breathing process in the human organism. These etheric activities have their primary point of attack in the fluid constituents in the human being. As you know, at least two-thirds of the human body consists of water, and in this water-organism the etheric body is chiefly active. The etheric forces express themselves physically in this water-organism. The forces of breathing find expression in the air organism built into the human being. Thus we may regard what takes place between the astral body and the etheric body as an interaction between water forces and air forces.

This interaction of air and water forces is continually ongoing in the human organism. Of course, neither completely suppresses the other; hence we always inhale traces of water vapor with the air. There the etheric element encroaches on the breathing. Similarly, the breathing activity encroaches on the digestive and nutritive organs. In so far as you are formed out of protein, you also breathe. Thus these activities always overlap, and we are always faced with a predominance of one activity or another in one organ or another. There is nothing here that can be described in a one-sided way. We can never describe this or that organ as being exclusively a respiratory organ. If we maintain this about the lung, we are in error. The other activity is always there, even if to a lesser degree. Nutrition takes place primarily through an activity that impresses itself on the fluid-etheric and on the solid-physical. Therefore nutritive and digestive activities occur primarily in the ethericfluid and the physical-solid, whereas the main respiratory activity is developed in the astral-airy, and the main ego activity, the actual spiritual activity, unfolds in the warmth conditions connected with the ego itself. Spiritual activity within the physical organism is a cooperation of the ego with warmth conditions, i.e., with all those organizations where warmth can work into the physical. The ego must always go hand in hand with warmth, must always operate through warmth. If we put a patient to bed and tuck him in, this is simply an appeal to the ego to make use of the warmth generated in an appropriate way.

These considerations provide insight into human nutrition in general. Nutrition is an interaction between tissue fluid—i.e., the watery constituent in which nutrition and elimination chiefly take place—and the protein organism of the human being. The latter is, relatively speaking, extraordinarily stable; it is labile in a certain respect only during the period of growth, then becomes stable and undergoes a kind of disintegration during the second half of life. In the tissue fluid there is a continual assimilation and disintegration of the protein in food. It is in this activity that attacks are made on that which wants to remain stable in protein formation: the human being's inner proteinaceous organs generally; they want to remain stable. This is because they wish to liberate soul-spiritual activity inwardly, to isolate it within. What is achieved through the process of nutrition is this continual interaction between the extraordinarily mobile play of forces, constituted by this active assimilation and disintegration of protein, and the play of forces striving towards rest that arise in this interplay of the inner protein in the human being. Hence it is partly a superstition, partly correct, to say that the human being builds up his body through the substances he absorbs from his food. It is a superstition because the constructive forces are already present in his proteinaceous body simply by virtue of the fact that a human being is a human being; on the other hand, the human being unfolds an activity from the other pole, which conducts a continual attack on this stability of his own proteinaceous formation.

We may say then that it is incorrect to believe that human life is maintained only by the consumption of food. This is simply not correct. It would be just as correct to say that life is maintained by the active interplay of forces in the tissue fluids. When you give food which stimulates this activity in the tissue fluids, you maintain life. This does not happen by merely introducing food substances into the body but by the encounter with the stable forces of its own proteinaceous constituents. This is a process that you stimulate by absorbing food, and this process is the most fundamental factor in the maintenance of life. Here, too, we find that we have to look at the process. It can be, for example, that substances we know to be effective in children do not necessarily act in the same way in an adult; for a child is developing his body and needs the introduction of substances and the unfolding of their forces in an inward direction. If you know that something is effective as substance in a child, it will not be similarly effective in the adult. In an adult, it may be much more necessary simply to maintain and stimulate the forces in his tissue fluids that are striving toward rest.

If you now study everything that takes place in the human organs with a backward orientation, as it were (the head is also such an organ), everything taking place in the lungs and liver, and then turn your attention to those more embedded in this activity of the tissue fluids, you will find the heart enclosed by the lungs as the archetypal organ. The human heart is entirely formed out of the activity of tissue fluid, and its activity is no more than the reflection of this inner activity.

The heart is not a pump! I have often said this; it is rather an apparatus for sensing or registering the activity in the tissue fluid. The heart is moved by the circulation of the blood; it is not the pumping action of the heart that moves the blood. The heart has no more to do with human circulation than a thermometer does with the production of outer heat or cold. Just as the thermometer is nothing more than an instrument for registering the degree of heat or cold, so your heart is nothing more than an apparatus for registering what takes place in the circulation and what flows into this from the metabolic system. This is a golden rule that we must heed if we wish to understand the human being. In the belief, that the heart is a pump driving the blood through the blood vessels, we can see how modern natural science reverses the truth. Anyone believing in this superstition about the heart ought to be consistent and believe that it is warmer in his room because the thermometer has risen! This is the consistent conclusion of such an approach.

You can see to what results one is led by views that simply do not take into account what is by far the most significant aspect of man's being: the soul and spirit. Such views ignore the mobile, the dynamic aspects and proceed from what is merely material, trying to draw from the substance itself those forces that are only imprinted on the substance. Such views want to attribute to the heart the forces that are only imprinted upon it by the dynamics, by the play of forces in the human body.

In the heart activity and in the heart organ we really have the most advanced organization of what is placed over against respiration and the liberation of the spirit in man. This may now be called a polar metamorphosis, in contrast to a mere transformation. In the head, lung, and liver, you have various stages of metamorphic transformations. But as soon as you study the heart in relation to the lungs, you have to speak about a polar metamorphosis, for the heart in its formation is the polar opposite of the lung.

All those organs that develop in a more forward direction—for example, the female uterus, which is the most prominent example—are then further transformations, step by step, of the heart formation. (I speak of the “female uterus,” because there is also a “male uterus,” but this is only present in the male as part of the etheric body.) The uterus is nothing other than a transformed heart. With this method of studying things, we can gain all that is necessary to understand this organization in the human being.

The fats and carbohydrates now intervene in this other activity that has its center in the heart—if I may put it so—and comes to rest in the heart's movement. The fats and carbohydrates exert their activity here. Of course, this extends over the whole body, because the whole body deposits substance and is a functional outcome of systems of forces directed toward combustion, just as the whole body breathes and develops what is spiritual.

This sheds some light on pulmonary tuberculosis and we will see how such an inner study of the human organism leads us further and further toward therapeutic matters. What was formerly called consumption—and has now been labelled tuberculosis for purely theoretical reasons—is really due to man's being cut off from the extra-terrestrial and confined to the earthly through various influences such as poor housing and so on. All descriptions of pulmonary tuberculosis can be summed up by saying that the patient is being cut off from the sun and cosmic space and is drawn toward what is cutting him off. He is drawn toward that which paralyzes his delight in the extra-terrestrial. This delight depends essentially on sense perception. The patient's soul cannot penetrate to the senses and retreats down into the lungs, so that the lungs strive to become an organ of thought, to become a head. This is, in fact, revealed clearly even in the pathological manifestations. In wanting to become a head they take on a form and one can see that the forces tending to ossify the human head then come to expression in the lungs, resulting in indurations, consolidations, tuberculomas, and the like.

How can this tendency be opposed? If you want to work against this tendency of the lung to become “head,” you must realize first of all that we have to do with a weakening of the required astral activity and with an excessive strengthening of the ego activity. This activity of the ego begins to overpower the astral activity. This must be remedied. Sense impressions from outside especially stimulate ego activity, but sense impressions from outside pass into the whole human organism by bringing about salt depositions. These are not properly regulated in a person with a tendency to pulmonary tuberculosis. Hence you must help in such a case by using rather strong salt rubbings to try to oppose, at the right moment, what the lung can no longer oppose. Salt rubbings, applied from outside, oppose the consolidating processes acting from within. Of course, one must form the whole treatment in such a way that the organism is inclined to receive what is introduced in the effects of salt from outside. The patient could also take salt baths, strong salt baths, but then the organism must be led to become disposed to work upon the salt within, i.e., to respond from inside.

Here we can be led to the following considerations, which follow partly from our discussions last year. If you wish to stimulate the organism to develop an activity from within that interacts with and regulates certain outer organizing forces, you must give mercury in small doses, i.e., in doses approaching the homeopathic. Mercury is an important remedy in this direction, an important means for regulating this. Here you will have to take into account something of general importance regarding dosages. Putting together all I have presented, you can conclude that the system most similar to outer nature is the metabolic-limb system. If something is lacking there, you must use the lowest potencies. As soon as you have to deal with the middle system, you need intermediate potencies. When you have to work with the head, when something has to do with the spiritual in the head, you have to work with the highest potencies. But in this case we are dealing with the lung activity, i.e., with a part of the middle human being, and an intermediate dosage of mercury must be used.

Whenever one intends to work primarily upon the head organization and from there back upon the entire organism, the highest potencies are required. These will be particularly beneficial in cases where one believes that something can be achieved with compounds of silica. Silica compounds require the greatest dilution by their very nature, for they always rise toward the head and the periphery of the body, which belongs to the head system. On the other hand, when you have occasion for other reasons to administer calcium compounds, you will usually do right not to use the highest potencies but lower ones. In short, the potency required will be determined by whether, in your view, you have to act on the metabolic-limb organism, the middle, rhythmic organism, or the head organism. You must bear in mind, of course, that the head organism works powerfully upon the whole organism from the other direction. For example, you may believe a patient to be suffering from a foot disease, but actually this may be a disguised head disease, having its origins in the head. In such a case you will have to effect a cure not from the metabolism but from the head. Thus one must use high—but not too high—potencies of a substance perhaps known to be valuable in lower potencies in cases that have to be treated from the metabolism. Gradually a rationale can be introduced into these deliberations, and this must be done. The details will become clear only when you consider precise observations yielded by experiments. The investigations must pursue these details in the directions I have suggested.

Only an individual who can carefully retain in his memory all that his experience has taught him will be able to speak about healing in detail. Every individual experience is obviously instructive and bears fruit for further experiences. If you consider then what I have said, it will no longer appear so puzzling that there are diseases that, for instance, attack the brain and the liver simultaneously, for the liver is only a metamorphosed brain. If you therefore find deterioration of the liver together with degeneration of the cerebral ganglia, these conditions run in the same direction, and you have a form of disease that is an intensification of what causes pulmonary tuberculosis. It is only an intensified metamorphosis of pulmonary tuberculosis. Hence internally you will have to give stronger doses of mercury. Regarding external treatment, you should not be content with salt rubbings and with baths of table salt (sodium chloride); instead you will have to use calcium salts.

You see now, however, that sources of error are everywhere, and one really finds what is right only if the human organism is studied from within. Imagine that someone can go and say, “Here is a disease that I will cure with mercury,” he may achieve some success. The disease, however, may have nothing to do with syphilis, but at some point this person got the idea that when mercury effects a cure, the disease must be connected with syphilitic processes. This is not necessarily the case at all. You will now better understand what I said last year when I spoke of "mental illnesses." Of course I meant paralytic disease when I spoke a few days ago of softening of the brain, but the description is not so vivid if one uses the word “paralysis.” One always has the feeling that one is dropping into a description of the outer complex of symptoms.

Questions now arise regarding what I said last year about the actual causes of psychological diseases. As I said then, these have to be looked for in deformations of the organs. One gets nowhere if one merely takes into account the psychological symptoms. Similar psychological complexes can even be traced back to totally different causes of illness. Especially in so-called mental illnesses we are led more and more to deformations of the organs, to an organ that is not functioning properly, and then the question arises as to why the organ is not functioning properly. It is because the stable—not the variable—forces in protein formation have become defective. Something in the patient is therefore continually striving to destroy the original plastic structure of the affected organ. Therefore it does no good to look for the cause in what is going on in the tissue fluid, which presents the other pole, the metabolism. If we proceed from the symptoms, it will not help us to study what is presented by the metabolism itself within the organism. Instead it is exceptionally important in trying to gain knowledge of mental illnesses to study the excretions. An important reference point will always be found there. It is of tremendous importance to investigate the excretions of mental patients, for—as I said last year—in certain forms of mental illness there is a compulsive tendency to form imaginations, inspirations. This is what “freeing the spiritual within” signifies.

This tendency is there because the organ has become defective. If the organ were not defective, if it were constituted normally, it would indeed form imaginations, but these would remain unconscious. When the organ has become defective, it is not able to form imaginations correctly. On the one hand, the organ is defective and the tendency to form imaginations arises; on the other hand, imaginations remain uncovered by the organ, and hallucinations arise. You could say then, that when we have an organ with imaginations developing within it (see drawing, red) which radiate through the rest of the human organism (see drawing, bright) and become perceptible, we are dealing with a deformed organ. The formation of imaginations (red) cannot unfold properly in its plasticity. As a result, because the imaginative activity is abnormal, it intrudes upon consciousness, and visions and hallucinations arise. On the other hand, the organ is damaged, and this gives rise to an urge to form correct imaginations. Only by seeing through these things from within can they be explained.

We will proceed tomorrow to answer individual questions that have been posed and to an explanation of our remedies.

In turning our attention now to the study of remedies, we will also discuss the remedies we have already introduced. I have no interest, of course, in describing how the idea forms in me that this or that can be a remedy. Instead I want you to come to an insight into why this or that substance can be used as a remedy. I would like the perception of the remedial value of a substance to be formed, as it were, in your own souls. Therefore I would like to direct the discussion today in such a way that we undertake a theoretical investigation of how one arrives at the view that something can be used as a remedy.

Of course it must be stated at the outset that an acquaintance with the main principles of an anthroposophical knowledge of the human being provides the basis for this. A correct interpretation of remedies can arise only if one is impelled from the ground up to conduct the whole investigation in an anthroposophical sense. Thus you will also see that what I have said in the last few days will flow into the theoretical investigations presented today.

Let us proceed from the fact that the interaction between the human being and his environment can be studied by investigating the plants. By first comprehending the processes in the plant world, one acquires a correct insight into the continuation of mineralizing processes into the inner aspects of the human being. In presenting this type of investigation, however, we must realize that something shaped out of the whole cosmos is at work in the entire process of plant formation—in the formation of roots, leaves, blossoms, seeds, and so on. This follows from everything we have studied in the last few days. This process that tends particularly to shaping the plants, even to shaping them inwardly, cannot be replaced by an artificial synthesis, by a chemical synthesis. At most, it can only be replaced in this way in very few cases. For example one must be clear about the following: In the roots of a plant we have to do with the part of the plant-forming process that is bound to the more-or-less inner forces of the earth's surface. Soul-spiritually, the human being is a being growing in a plant-like fashion from above downward. His head harbors many of the forces that interact with the forces of the earth itself. There is a deep kinship between that which shapes the root in plants and all the forces of the human head. Thus, when clear ideas need to be gained about the process that takes place in root formation in plants, it must always be realized that this process has a reciprocal relation to the human head.

Let us examine the root of gentian (gentiana lutea) as an example of how to explore such matters. Gentian is a plant in which the blossoming forces come to strong outward expression. Therefore in the root we will find forces that tend very strongly toward the blossoming element. In other words, the root's forces are somewhat weak, a great deal is expended in the direction of blossoming and leaf formation. Nevertheless, the whole form of the blossom shows that the root nature is still present very strongly. Thus we cannot count on gentian, as a matter of course, strongly affecting the activities in the human organization proceeding directly from the head, i.e., as outer physical effects. Rather we should expect gentian to act on what supports breathing from out of the head. Since effects in the organism always are polaric, we must imagine that especially the digestive organs begin to breathe very strongly in the way I explained yesterday if we administer gentian roots. This stimulates an active breathing activity in the stomach and intestines, but we must keep in mind what we have learned in these lectures regarding the necessity of first treating the plant substances if these are to stimulate this breathing activity. We must boil the roots, and administer the decoction.

Let us now turn to some external aspects of the plant. We notice that the gentian root has a bitter taste and a strong smell; thus it acts very strongly on the astral. We therefore have an effect on the astral nature in the digestive realm of the human being. Moreover, gentian root contains sugar. You will recall that I have frequently pointed out how the process of working through sugar in the human organization involves a strong stimulation of ego activity. I have said that you can study this even in external statistics. For example, Eastern Europeans and Russians, in whom the ego activity is somewhat withdrawn, use a very small quantity of sugar each year, whereas the statistics show a greater consumption of sugar the further West we go, i.e., among the English, in whom the ego develops an extraordinarily vigorous activity. Such things must certainly be taken into account if one wishes to gain knowledge in the world.

Gentian root is also rich in fatty oils. Fatty oils, when passing through digestion, have a strong effect on the lower breathing, since fatty oil intensifies the mobility, the inner mobility, of the stomach and intestinal organs. Therefore you can see how it is possible really to describe what is taking place in the human organism. One notices at once that the astral activity is stimulated and therefore that the breathing mobility of the stomach and intestinal tract is stimulated. One can therefore say that the intestines develop a greater activity and the stomach is strengthened. This whole effect is the result when the astral body is strengthened generally. The whole effect calls forth mineralizing processes, but only to the extent that these solidify the organs and make them stronger. This is the slight influence of the ego acting through the sugar. Thus if we use a decoction of gentian roots, we stimulate the activity of the astral body and, acting through the sugar content of the root, allow the ego to assist.

There is a danger, however, of the ego going too far. If the ego continues to work below like a whip, a reaction is set up polarically in the head, and one can observe that such patients suffer from headaches as a side-effect. Nevertheless, the effects I have mentioned are produced. We observe an intestinal activity that is essentially of an enhancing, stimulating character, and we will use such a remedy, either alone or in some combination, if we notice that an illness manifests in connection with loss of appetite or dyspepsia, and especially if there is a generally sluggish digestive activity. In this way the metabolism is inwardly stimulated and becomes more active. By this means we can therefore work against tendencies toward gout and rheumatic conditions. In addition, in applying gentian root we will have made appropriate use of something that has a mildly antipyretic effect. This is because the deficient intestinal activity induces a reaction in the upper human being, and the febrile activity proceeds from this. Thus if we strengthen the lower human being, creating a counterweight to the upper human being, we have introduced an antipyretic activity.

This is the approach we must take if we wish to come to concrete relationships of the outer world to what is within the human being. It is quite correct to draw attention to currents acting on the human being from outside. In this respect, a man like Rosenbach has made remarkably good preliminary studies. However, if we only speak about these currents in abstractions, we do not at first realize that what acts from outside emerges from concrete things. It emerges from the fact that such relationships prevail between the root-nature of the plant world, the forces that are active in the root nature, and these forces once they have entered the human being. In this way we grasp things that otherwise are only characterized abstractly as currents. Spiritual science is concerned with working out of concrete processes.

Let us study a most instructive plant from this standpoint—the clove [clove root] (geum urbanum). We will again take the root and prepare a decoction from it. It is extraordinarily interesting if you investigate the clove root and recall something of what was said about the gentian root. Of course we must again assume an interaction with the head forces, because we are dealing with the root. Now clove root has a tart taste, exceptionally tart. In clove root we have etheric oils, i.e., oils that we must assume act on those parts of the organism not situated close to or within the intestinal tract, like those we spoke of in discussing the root of the gentian. Rather we have more to do with what should take place in the stomach, or perhaps only in the esophagus. We must also take into account another most essential fact here, namely the starch present in the clove root. Therefore we must appeal to forces that work in a more intensive way than the forces that are necessary to digest sugar. To digest starch, the process has to begin earlier. The sugar has first to be produced. You see, one must really pursue the processes in detail.

The clove root also contains tannin, and this too we must take into consideration if we wish to investigate the remedial effect of anything. Tannin points to the fact that the starch is working more toward the physical, becoming something that cultivates that which opposes even tannin. In the case of the clove root, then, the whole effect must be ascribed more to the ego than to the astral body. We have here an intensification of the ego's activity. Because of this, we have to do with what takes place in the lower human organism. This effect is a complete polar opposite to the stimulation of the head that takes place through the ego. We have to do with what I would like to call the outer digestion, laying hold of substances while still in the stomach, before they have gone over into the intestinal activity. Every system extends through the entire human organism, and the part of the nerve-sense apparatus still present in the intestines and digestive organs is stimulated; we therefore have to do with a predominance of the ego's influence.

What is the consequence of this? First, we have in clove root a strong antipyretic force; second, by working on the earlier digestive processes we can affect those later on, i.e., the actual intestinal activity. We give the intestinal activity less to do. In this way we can combat diarrhea in particular, and also mucous discharges from the intestines, for these things are due to overburdening the inner digestive activity. Thus you see that these investigations lead to a perception of the way outer forces penetrate what is within the human being.

This study of roots is of special significance, so let us take another root, for example the the root of iris germanica. Here we will also prepare a decoction from the root. The iris shows us even by its outer manifestation that it works strongly on the ego. The repulsive smell and bitter taste of the root reveal at once that the ego here interacts strongly and physically with the outer world. In the iris root there is something that stimulates this physical activity very much, that is, tannic acid. We also find something else that works upon the ego activity: starches. Finally, we find something that, through its physical effect, has an influence wherever it is stimulated to do so; we have resins in the iris root. Through all this the ego is brought into an especially lively activity. This lively activity of the ego—this driving force of the ego—can be noticed first in the urine activity, where a purgative, diuretic effect appears. These are outward expressions of ego activity.

We can find the conditions treatable by this remedy if we simply ask, “What is the human organism suffering from when these things are not in order?” The answer is dropsy and similar conditions. In decoctions of iris root we therefore have something with which we should try to combat dropsy and similar edematous conditions.

In taking a step upward in our study of the plants, let us consider the green leafy parts of the plant. We will take a characteristic plant like marjoram (majorana origanum). We must realize, when we come to the leaf, that nature herself completes certain processes that we must first carry to completion in the roots. When we take the leaf therefore, it is not good to prepare a decoction directly. We need the finer forces of the leaf and can obtain these by preparing an infusion. The forces that we really need are made available through preparing the leaf in an infusion. Here again you can grasp what we are dealing with by means of the senses. The infusion of marjoram has the peculiar flavor that might be called the “warming” flavor. At the same time, it has a certain bitterness. Then you have the aromatic smell, the ethereal oil, that proves so clearly that here something is working outward. In addition, you have something that need only be added to intensify all this, but whose physical effect does not manifest as early as other products. This aspect does not appear in its physical effect until it has passed through the stomach and has reached the intestines. These are the various kinds of salts present in the leaf, especially in marjoram. You may therefore say that this leaf-infusion has a particularly strong effect on the breathing activity of the inner organs: it calls forth a certain breathing activity in the inner organs. This finds expression in the sweat-provoking effect of this infusion, i.e., the inner organic activity in the form of breathing is stimulated. It has a diaphoretic effect, and the reaction therefore strengthens the activity of the inner organs. With infusions of marjoram leaves, one can work on the one hand against upper respiratory congestions, rhinitis, etc. and on the other hand against uterine weaknesses.

All this will become clearer when we move on to the effect of blossoms. Let us look at this effect in an instance where the plant shows it with special clearness, for example, where many small blossoms are clustered together in an inflorescence, as in the elder (sambucus nigra) or lilac. Let us be quite clear that here the plant is penetrated by precisely those forces that have a great deal to do with the environment of the earth, that contain cosmic influences, cosmic radiations. From this we note that elder flowers also contain ethereal oils. We notice it particularly from the fact that these flowers contain sulfur. In these flowers we therefore have something from the mineral kingdom that proves especially effective if we wish to stimulate breathing, but now from the other side: to stimulate the actual breathing organization, whereas earlier we spoke of stimulating breathing in the digestive organs and organs near them, before the breathing of the actual respiratory organs intervened. When we use elder flowers in the form of an infusion we stimulate particularly the etheric activity of the human organism, and only by way of this etheric activity do we stimulate the activity of the astral body. It is especially the breathing in the upper, posterior organs that is stimulated, not so much the head organs as those belonging to the actual respiration. Of course, reactions such as purging and sweating naturally appear everywhere. Now, however, the organs of breathing are stimulated. The normal breathing activity is intensified and—because this has to have an effect on the blood—the blood circulation is stimulated from inside the human being.

We can immediately conclude from these observations that it is possible to work against catarrhs by such means, and also inhibited sweat-formation, hoarseness, and coughing. And, because the effect that before appeared directly, now appears polarically, we can also use this remedy in rheumatic conditions. It is always a question of determining what curative forces a remedy may contain from the way it acts.

Let us now consider situations in which it may be necessary to act especially upon the head organization. What is it that really depends on the head organization? Digestion, its polar opposite, depends on it. Indeed, the cruder digestive processes, the cause of so many serious illnesses, depend on the head organization. Hence we must realize that we can influence the head through the cruder digestive processes. If we want to support what takes place within the human being—thus having an effect on digestion—so that the substances stream up into the head and are therefore able to unfold their effect from there, we must naturally do everything we can to bring this about. Therefore, although we want first of all to introduce the plant substance to the inner part of the body, we must form it in such a way that it works into the head. We can observe such an effect especially when we make use of seeds. Seeds by their very nature are especially suitable to influence the cruder digestive processes. And by acting directly on the cruder digestive processes, they act on the head in calling forth reactions. Nevertheless, it is very difficult to promote the effect from the digestion to the head. Therefore it will be useful to make a very concentrated decoction of the seeds, if this agrees with the patient. We can study this especially well if we consider the effects of decoctions of caraway seeds. These contain ethereal oils, which act essentially upon the ego; wax, which has a very strong physical effect; and also resins, which also unfold strong effects in the physical. The powerful effect is also shown by the aromatic smell. In addition, this decoction contains levulose.

If we consider all this in connection with what we have studied in the last few days, we will see that it strengthens the activity of the ego to an extraordinary degree. It affects the nerve-sense activity concealed in the digestive organs. It works especially on this weak nerve-sense activity in the digestive organs—this activity extends throughout the digestive organs in a very faintly formed metamorphosis. The effect of such a decoction on the lower human being resembles what one might call a subconscious metamorphosis of our outer sense perception. We are stimulated to perceive with the digestive system what is developing as process there. Hence this remedy is very valuable when administered through an enema. When given by enema, it calls forth a process that must act on the nerve-sense activity. This is an outer administration of the finer forces of the caraway seeds, and in this way a kind of subconscious perception is evoked in the digestive organs. The lethargic tissue fluid is especially stimulated by this means. By thus introducing a process strengthening the nerve-sense activity, perception is driven much further into the human being. The patient becomes a perceiver in his digestive organs, and this works against the opposite pole that we find when an inner activity begins that can also be perceived—consisting, indeed, of inner perception—when our organism begins to express itself in eruption-like states. By our strong perception of our organism when it develops such an organic activity, so that we are actually perceiving ourselves, we dampen down such activity and therefore have a curative effect on it. Such an activity represents a perception from within outward, a nerve-sense activity similar to, though a metamorphosis of, outer perception. Thus we can work beneficially with this remedy in cases of stomach cramps, colicky conditions, and flatulence.

Yet another process is extremely interesting to observe. Picture vividly to yourselves the subconscious process developed in such a case. This subconscious activity is extraordinarily similar to the activity of outer sense perception, but it takes place within. Consider that the outer activity of perception and the reflex activity are connected in a certain way. Perceptions that appear subconsciously can call forth defensive movements immediately. Study this cooperation of perceptive activity and the reflex reaction against it, and carry this over to the inner activity of the tissue fluid. You carry out this outer perceptive activity in floating in the air, in a sense. Sketching this schematically, let this be the air in which we carry ourselves (see drawing, bright). It is permeated with light, etc. Outer perception (red) unfolds in this direction; the inner reaction (blue) unfolds in this direction. In every sense organ there is a cooperation between external action and inner reaction. If you want an outer, abstract picture of this process, you should not choose the one chosen by the modern materialistic view, namely, that of a centrifugal and a centripetal nerve activity. Such a view is no more intelligent than saying: when a rubber ball is pressed it recovers its former shape by means of another force, i.e., by the counterpart of the pressure itself. It is no more intelligent to speak of motor-nerves than to explain the elasticity of a rubber ball by ascribing to it some center within that pushes out what has been pushed in. What happens in both cases is really no more than the restitution of the original form; it is the reaction that sets in, requiring no special nerves, because the whole phenomenon—action and reaction—is embedded in the astrality and ego nature.

Now picture this whole process working by way of the etheric activity in the tissue fluid (see drawing, yellow). Of course, a sense process does not take place in the tissue fluid under normal conditions, but it can be evoked in the way I have just indicated. A kind of contracting tendency arises, a tendency to work in toward the organism, and I will sketch that in this way, just as I indicate here the action of perception. But this (see drawing, red) is a process that in a sense assaults the outwardly directed forces in the tissue fluid (violet). Here is the action, and this is the reaction. Thus one is inserting a sense process, a metamorphosis of the sense process, into the tissue fluid. It is extraordinarily interesting to observe this insertion of a metamorphosis of the outer sense process into the tissue fluid. Now we must search for something similar that takes place in normal life, that is, some condition in which a kind of metamorphosis of these sense processes within the human being, a densified sense process, arises in the tissue fluid. This takes place when a woman secretes milk. Here, in fact, we have a densified metamorphosis of the outer sense process transferred inward. Now, if this milk secretion is deficient when it is supposed to be there, we have every cause to intensify this densified internal sense process in the tissue fluid. We can evoke this process with a decoction of caraway seeds, thus supporting the secretion of milk.

I have presented these things as examples of the way the whole working and weaving of the human organism and its connection with the outer world can be considered. Consider precisely what I have said: that a decoction of caraway seeds contains resin and wax, i.e., something whose consistency evokes very strong physical effects. Resin and wax are thereby very similar to what makes an impression on me from outside, only inwardly densified. This seed also contains etheric oils and levulose. This is something that stimulates the reaction of the ego. Taking all this together, you have everything contained in the sense process: action from outside, and the reaction extending to the ego from within. If you now metamorphose this sense process by not creating a sense impression but transferring this interaction inward into the tissue fluid's system of forces, you then have what evokes an inner sense process in you. The secretion of milk is such a process. You will see how the entire organization can be understood in this way.

These are the matters you must study if you wish to consider the effects of the substances of the outer world within the body. For example, if you study the effect of metal-mineral remedies, you will readily understand what you have learned from the influence of the plant element, but you will also realize something else: that the mineral element has undergone a change in passing into the plant process and continuing its activity there. In this mineralizing and “vegetabilizing” process, a transformation of the mineral forces has taken place. Part of the healing process thus depends on the transformation of the mineral forces. Imagine we were to build a sanatorium in the country. Then we could surround it with fields and manure these fields with various mineral substances, creating a soil whose content is known to us. We can sow there various plants from which we will use the root, leaf, fruit, and so on. Thus we will have control of the process by which the plant transforms the mineral into a remedy. We can strengthen this process by growing the plants we have just discussed and treating them in the way I just mentioned. We want to do this at our Research Institute in Stuttgart, but this must still be arranged. One can go still further, however. One can take what has been obtained from the plant itself as a remedy and can use it as a kind of manure, thereby intensifying its force. In this way ordinary triturated preparations will be made much more effective, for nature herself, and the forces active in nature, are allowed to do some of the work of preparation.

Of course we have to be clear about the following: for example, how should a mineral-metallic remedy act in order to have an effect? Salts, which are really mineral remedies, produce effects more toward the inside of the human being. The most peripheral activities, however, are influenced by just those mineral-metallic substances that are most firm. Here we have a direction for research, but always on the basis of spiritual scientific knowledge, for otherwise our thoughts will split up and run in every possible wrong direction. The thoughts of spiritual science guide our thinking in the right direction. When we look at a metal, we know it can only be weakly taken hold of by the inner human organism. There the activity of the ego must be highly stimulated, for it is the ego that, in a sense, undermines and penetrates into the interior of the substance, shaping this for its own purposes and summoning it to ego activity in the organism. The ego can be strengthened in this activity by the astral body. Thus when we make use of metals or minerals, we must always see whether we are stimulating the ego activity or the astral activity that then works back on the ego, or whether we are stimulating the interaction between the astral and ego activity.

Such stimulation can be achieved, for example, in the following way: We prepare a metallic ointment and apply it, let us say, to a skin eruption; we thereby stimulate the peripheral ego activity. This ego activity is similarly stimulated by a reaction within the human being. This arises within the human being first in an intensified nerve-sense activity in some organ. This leads from there to an intensified breathing activity, passing over to the astral. The effect is that those forces within the body then work against the skin eruption. We appeal to the whole body to work against the skin eruption.

On this basis the various metallic and mineral substances can be studied in a similar way. In lead, for instance, you have a substance that acts with extraordinary strength on nerve-sense activity, and then, dependent on this, on the inner breathing activity, including the inner breathing activity that takes place in the outer, peripheral organs, for example. If we use lead, either as an ointment or internally, we can achieve a good deal when it is necessary to evoke what I have just described. When we give it internally, however, we must realize that we are evoking the reaction of the upper human being by means of the activity stimulated in the digestive organs. If we apply carefully prepared lead ointment to the upper human being, we act directly on this upper system. In patients suffering from weaknesses in the head region—i.e., in which the upper human being develops neither a proper nerve-sense activity nor a proper breathing activity—we will be able to achieve a great deal with such lead cures, provided we do not go too far and cause lead-poisoning.

We must take into account something else with everything we may gather from the presentations in the last few days and in the previous course. It is most important to be aware of a great contrast here. Those substances tending more toward silver have a polar relationship to those tending more toward lead. In regard to these matters our classifications of minerals are most deficient. These defects are fundamental, for a reasonable classification of minerals would have to take into account these family relationships of the metals. We should see lead and its compounds at one pole, and at the other pole silver, while gold, for example, would be in the middle, and the other metals arrayed appropriately. I call silver and lead opposites because silver acts directly on the metabolic- limb system, especially on its periphery, on the part of the metabolic-limb organism that lies nearer the surface. Lead acts, likewise, on the part of the head organism lying closer to the surface. Thus silver stimulates the nerve-sense activity in the metabolic-limb system and from there calls forth the activity that permeates the whole body and that stimulates the breathing in everything that yesterday I called a metamorphosis of the central heart organ.

On the other hand, what proceeds from lead works on the nerve-sense activity of the head and on the breathing activity stimulated from there. Hence it stimulates the head formation, lung formation, and liver formation, that is, the organs belonging to the other path of metamorphosis. These organs in a sense surround the other organization of the human being, just as the lungs surround the heart, showing us the archetypal form of that which, as the “circulatory human being,” is in a certain respect the whole human being. We have the lungs surrounding the heart, the lungs embracing, as it were, the circulatory being with the respiratory being. Likewise, when we study the human being in regard to his brain formation, lung formation, and liver formation, that is, the whole upper posterior human being, we have a more all-encompassing breathing embracing all the blood vessels together with the heart. The digestive organization and also the sexual organization are surrounded in this way by the upper posterior human being. The human organization is such that the upper posterior human being surrounds the lower anterior human being. We must thoroughly understand the mutual relationships and differentiations of the upper posterior human being and the lower anterior human being, which comes to expression primarily in the interrelationship of heart and lungs; we must study this properly, the rhythmic interplay involved in this, the nerve-sense activity lying above and to the back, and the opposite pole in the metabolic-limb processes lying below and to the front. We must study the other manifestations of the upper and lower human being, and only then will we have the whole human being before us. Only in this way can we then master his other processes as well.

From this starting point, we will move on tomorrow to a special discussion of our individual remedies. In doing so, we will naturally be led to deal with some of the questions that have been posed here.

Today's lecture will be an assortment of various topics I would like to add to what I have already said to you, including reference to our remedies. I would like to begin by saying that processes related to the mineral element that affect the human being can be interpreted similarly to the way done yesterday regarding the plant world. However, the insights we must gain here are more complicated, because as soon as we move on to the mineral world we are no longer dealing with definite, self-contained entities encountering each other, as was the case with plants and the human being; instead we are dealing with a realm in which one object passes directly into the other, so that it is difficult to make distinctions.

In the preparation of remedies—to this you must pay particular attention in our remedies—it is not merely a question of using some substance or other; the process in which the substance lives must be captured in another process. Thus when the effect of some remedy is known to you, it is often a matter of taking the effect you evoke on one side and damming it in from the other. You can see this clearly, for example, with the remedy we prepare from lead and treat in a certain way with honey (you will find this process described in detail elsewhere). You can see how the effect of lead must be held in check in one direction by the effect of the honey. Lead exerts a very strong influence on the formative process proceeding from the ego in the human being. We have spoken of the fact that in the head formation of the human being—or, said better, in the head formation proceeding from the human being—there lies a physical influence, but also an etheric imprint, an astral imprint, and an ego imprint. We said that the ego essentially imprints itself into the system of movement. The effect of lead works especially strongly on this imprint of the ego and takes place in conjunction with the astral imprint.

In the effect of lead we have a force of nature that is extraordinarily well-hidden, and for occult observation it is of exceptionally deep significance to experience this effect of lead. The effects of lead are extraordinarily important for the human being before he prepares to descend into physical life. This is when the effects of lead must be taken into account. Indeed, lead acts not only in the ways we know, but it has effects that are the polar opposite as well.

These polar effects radiate in from the cosmos, whereas those known to us radiate into the cosmos from the earth. This could be represented schematically like this. If this is the surface of the earth, the lead activities known to us radiate outward from the earth (see figure 1, arrows); the polar opposite effects stream in from all sides. They have no center from which they radiate, for they are not central forces but forces operating from the periphery (red). These peripheral forces are especially concerned with the formation of the soul-spiritual in the human being, and their domain must essentially be left when the human being prepares to descend into the earthly sphere. Hence in the earthly sphere lead is induced to unfold its opposite forces, and these are the poisonous ones. Everything connected spatially with the soul-spiritual in the human being, that is everything that can be spoken about in relation to space, is poison in the human organism.

This is a universal mystery to which one cannot pay too much attention. The meaning of the concept of poisoning must be sought here. We have to do with a strong stimulation, a powerful excitation of these ego-imprinting forces in human nature. Everything that arises in lead poisoning tends to destroy the form of the human being in so far as he is an ego. It dehumanizes him. In fact, all the symptoms of lead poisoning terminate in an individual gradually passing into nothingness corporeally. These symptoms include failure of the voice, stupor, and syncope, and attest to the fundamental destruction of the inborn formative force in the human being. Of course a person dies before this point is reached. The human formation is being destroyed from the upper human being, which is the polar opposite of the lower human being. What in greater quantities acts destructively in the upper human being acts in small quantities—in dilutions—constructively in the lower human being.

At this point I would like to interject something. I believe the never-ending conflict between homeopathy and allopathy will not be set right until one is able to enter into a study of man's constitution as given by spiritual science. On the one hand, the rich treasure of experience does not—or at least, should not—allow us to doubt the principle of homeopathy; on the other hand, people who are not in the habit of judging purely by experience but are swayed by all sorts of prejudices and opinions about the human organism cannot easily understand that what can make a person ill in larger doses in smaller doses makes him well. The homeopath is always more of a phenomenalist than the allopathic physician, who is always swayed in his therapeutic rationale by all sorts of prejudices. The facts are not fully revealed by this simpler statement, however. They are discovered only when we say: what makes a person ill when working in large quantities in the lower system will make him well when working in small quantities if its effect can proceed from the upper system and vice versa. This restatement of the homeopathic rule is the means to set right the conflict between homeopathy and allopathy.

Let us return now to the attempt of preparing a remedy from lead and honey. You can see how lead, greatly diluted and acting from below up, works against the destructive force acting on the human form. This is part of lead's effect. However, if one tries to build up this ego-shaping force, one transfers the activity of the ego into the physical organism and, while making the patient healthy bodily, one renders him psychically weak regarding everything that should work from below upward, that should work even organically. This weakening can go so far that one may, on the one hand, restore the individual to his human form, as it were, having been led by certain processes of disease to use the effect of lead because the formative processes are lacking. On the other hand, one may easily undermine the forces proceeding from the ego and astral body—especially those from the ego—when one causes the individual to develop his formative forces again. You could say that one brings about a cure for what the individual has not acquired, or has acquired only incompletely on entering life, but one weakens him regarding what he ought to do organically for himself during life. The effect of the honey when added to the remedy, however, opposes this weakening, that is, it strengthens the forces radiating from the ego. You see, in arriving at such a remedy, it is essentially a question of gaining insight into what is really taking place in the human being.

If we wish to understand the effects of the mineral element in the human being, however, we must look at the general effect of the mineral in the earth. It is necessary first to become acquainted with the significance of salts in the evolution of the earth. The significance of the salts in earthly evolution is that the earth actually produces them. In salt processes we find what the earth brings into being. In developing salts, the earth builds itself up. And when we turn from the salts to the acids—looking, for example, at the acid's element present in the watery earth regions, we have the earthly process corresponding to, though the polar opposite of, the inner digestive process in the human being, that is, the digestive process beyond the stomach.

We need to study all these processes taking place in earthly development, inasmuch as they represent a relation between acids and salts. When we consider the process that develops from bases through acids to salts, which can be observed outwardly today in chemistry, we see that, regarded in this way, the process leading from base to acid to salt coincides with the earth-forming process.

This process is essentially a negative electrical process. To put it more exactly: this process, expressed in its external, spatial aspect—i.e., as a process working its way out of the spiritual into the physical—can be represented schematically as follows. We have here an effect proceeding from the bases through the acids to the salts; it is indicated only in its direction here (see figure 2, red arrows), but it is actually a process of deposition expressed schematically. Now, when we express this process in reverse, passing from the salts through acids to bases, we must always remove these lines of deposition. They would act in a compressing way, and the opposite radiations appear, which radiate out (see figure 2 on right, arrows). Then we have to do with a positive electrical process. If you look at this sketch, I believe you will hardly doubt that it has been drawn by nature herself. Just look once at the anodes and cathodes and you will find this picture sketched by nature herself.

Now, if we approach the metallic process, that is, if we approach the metals themselves, we find in the metals that element by which the earth “unbecomes” (“ent-wird”) most, if I may use this expression, though it has long disappeared from the German language, despite the fact that it corresponds to reality: werden—entwerden—to become—to unbecome. With metals we find the tendency for the earth to disintegrate, to shatter in pieces, rather than the tendency to preserve or consolidate themselves in the earthly kingdom. They actually represent the “unbecoming” or passing away of the earth, and as a result they develop hidden radiating events, concealed even to external observation. You have this radiating effect everywhere. It is very important to observe this wherever we approach the metallic element with our interpretations of nature in an attempt to derive remedies.

It is especially interesting to study individual metals from this viewpoint. Such a study leads us to the viewpoint represented outwardly by this table of the mineral remedies we consider valuable. To arrive at these things it is necessary to gather everything yielded by such a correct interpretation of observations. They will be reliable, because we have prepared only those remedies that have their basis in a comprehensive interpretation of observations. Here we can elaborate on this interpretation, for I am really not concerned with simply repeating this list to you. Any additions that have to be made can be given in a written exposition. At some point this will have to be done. I am less concerned with repeating this list than with guiding your thoughts in the direction that could lead to such a list in the first place.

Let us now study the metals—I would prefer to say: the metallic nature—from this viewpoint. There we find what I have just described as a radiation, and it is present in the most varied forms. It can exist in the emanating form of radiation, destroying the earthly and passing into cosmic space. This is especially the case with the lead-activity. Through this lead-activity the human being has implanted into his organism those forces that would like to disperse him into the world. This dispersing into the world is an aspect of lead-activity, so that we can best regard this effect as a radiating one. Such radiating effects appear in a different way in other metals, for example, magnesium. This can be seen clearly and is the basis for the role magnesium plays in the teeth. Through the human organism this must be brought to the point of a metallic activity. This actually happens, but the radiation must then be able to metamorphose itself again. And when this radiation has metamorphosed, it becomes what I would like to call simply “direction.” The radiation is now only “direction,” what happens, however, is an oscillation, a pendular movement to and from this direction.

We must study such effects in the healthy and sick person. In the healthy person, these radiating effects are present in the radiations of the sense organs, as remnants, you could say, of the life before birth, of prenatal existence. These are always present. What radiates from the sense organs consists basically of after-effects of lead, in which lead itself is no longer present. These radiations occur throughout the entire organism wherever there is sense activity. Nerve activity, that is, the functional activity going on in the nerves, has its basis essentially on a weakening of the sense activity in this direction. This activity is therefore based on a weaker radiation. You can see from this why I said in my book, Riddles of the Soul (Von Seelenrätseln), that it is difficult to describe the actual nerve-sense activity, because I would first have had to introduce everything I have now presented to you.

In this oscillatory process, this pendular movement, in which the radiation is only considered in regard to its direction, we have to do with what functionally underlies all breathing in the human organism, in fact all rhythmic activity. Rhythmic activity is based on setting up such pendular movements, on setting up a movement more consolidated in itself than the movement of radiations. Among the metals or metallic nature, tin, for example, has such a movement. The beneficial effect of tin in fairly high potencies on everything that bears upon the rhythmic system is based on this fact.

This radiating, pendular movement can be modified further, however, and this third modification is of great significance. This third modification maintains its direction and also its pendular motion only latently. On the other hand, it consists of spheres continually forming and dissolving in the direction of the radiation. What has an effect on the metabolism in the human being depends on these forces, and among metals it is iron that develops especially these forces. Hence the iron in the blood works against the effect of metabolism as a third metamorphosis of the radiating activity.

When we are dealing with the first metamorphosis, the effect is especially on everything that organically concerns the ego; when dealing with the second metamorphosis, the effect is organically on everything that concerns the astral body; and with regard to the third metamorphosis, the effect is organically on everything related to the etheric body (see figure 3).

Now let us go further. What develops there as the continuous “radiation of spheres”—if I may call it so—must be continually received because it acts, in a sense, from the upper human being toward the lower. It only goes as far as the etheric. Now it must also be received by the physical by means of a force acting polarically, for something that envelops the spheres from outside must come to meet such a sphere-formation. The sphere must be taken hold of and enveloped (see figure 4).

It can be that the sphere-formation and this enveloping action are approximately balanced. This is naturally the case in a normal person, where everything that works downward from the upper human being is counterbalanced by the effect of the lower human being on the upper. This adjustment takes place especially in the damming-up activity of the heart. When this balance is disturbed, however, the metal that can bring equilibrium is gold, au rum. This restores the balance between this enveloping process and what lies in the middle. One will have to use gold when disturbances of the circulation and breathing occur that do not appear as results of something else; that is, when the causes are not to be found in the rest of the organism, gold will be applied. If, on the other hand, you notice that the causes proceed from a region other than the boundary between the lower and upper human being, you will be led to say, “There are not enough of these enveloping material processes coming from the individual to meet the more etheric-spiritual processes taking place here.” And if the activity you find here lies more toward the inside, in the digestive processes beyond the intestinal wall, you will assist this enveloping process by applying copper.

This leads us to the ways of using copper, which is included among our remedies. It is generally used in connection with a form of malnutrition manifesting outwardly in disturbances of the circulation that are consequences of the malnutrition. If we are dealing with circulatory disturbances that cannot be regarded as results of malnutrition, then we give gold; if circulatory disturbances are connected with malnutrition, we use copper.

Now, there must be counterprocesses also for the other processes of radiation, material counterprocesses to the etheric-spiritual processes. Consider the process that we must now regard as an inner process, which brings about this pendular movement, this oscillation. When it becomes abnormal, when it grows too strong, it can be observed in everything constituting the digestion, in working through the absorbed food by the intestines, and, coming more to the outside, all that is situated on this side. This therefore includes what occurs in sexuality, for example. The sexual processes are radiations from the human being that run their course in this way (see figure 3) like the staff of Mercury. This played a part in establishing the ancient so-called symbols. If what is active here is not to degenerate, it must be opposed by material, formative forces holding it in check and preventing this degeneration. These formative forces are essentially to be found in mercury. We are here pointing to a realm in which it is extremely important to bring together what I said in the last course with what a more inner study now teaches us. If you bring these two things together you will have the whole process before you. This is now something that plays entirely into the astral, arising through such pendular, radiating movements and through the corresponding counter-images. It now passes over entirely into the astral (see figure 3).

We may also be concerned with the actual radiation process that is present in the human organism in the most manifold ways. On the one hand, we find this process in everything that radiates out through the skin, in everything that has this directional radiation in it. We find this process in everything that causes urination, in everything that has an evacuating action in the human being. Just as in the gastrula stage of embryonic development the outside is drawn inward, so in this radiation we have to do with something that acts toward the outside through the skin but that also takes on the opposite direction and works in the processes causing urination and bowel evacuation. Usually we find the polar process expressing itself in an opposite direction, but here we have something that is, in a sense, reversed and yet similar. You see, one must not try to treat things in the world schematically. Errors always arise when we start from theories. It is impossible to start from a theory and not succumb to error. Thus if someone says to himself, “Polarity is at work in the world,” and then proceeds to construct a scheme or formula for polarity, saying that polarity must act in this or that way, he will be able to coordinate certain series of facts but he will have to abandon his formula in the face of other phenomena, where things are different. If only we could gain insight into this terrible tyranny exerted by theorizing in science!

Of course, one must be willing to make theories, for otherwise it would be impossible to coordinate any realm of phenomena. At the same time, however, one must be willing to drop one's theory in the right place and penetrate further to the point where this theory has no more value. Natural science must also pay heed to this. If one wishes to work on the theory of evolution in an outer sense, one must keep to the outer theory, modifying it where necessary. If one wishes to understand the human being from within, one must keep to what anthroposophy has to offer. But neither an anthroposophical nor an anthropological theory can be applied in any other way than by leaving it behind at the right point and passing into the other domain. With what we call anthroposophy, of course, we enter the soul-spiritual domain and return again to outer, sense-perceptible phenomena. You can observe how, in my early writings, I followed this path as a matter of course, and how in my more recent writings I am now trying to embrace the other domain as well. Only fools find devious contradictions in this and so construct their idiotic attacks. Then German journals, run by people who are incapable of judgment, publish idiotic attacks as a serious discussion on anthroposophy.

The point is that we must take into account this process that can be described as a radiation, as I have just done. Then we have to work against this, and we can do so by appealing to the opposite radiation, one active in silver, for example. In this connection we must realize that silver must be applied as an ointment if it is to have an effect on the kind of radiation that expresses itself through the skin; however, it must be injected in some form if it is to deal with the other activity that follows the direction of evacuation in some way. Here you have what I might call a “guideline” for the particular way in which to handle such matters. Basically, just as much depends on the way such things are handled as on the quality of the remedy.

This study has led us to the remedies, and I would like to conclude it with some comments in reply to questions that have been posed. If I have not been able to complete our program this time, I must ask you to excuse this due to the shortness of time. If you pay attention to my method of answering questions, however, I believe you will see from it that I have tried to shape the lectures of the last few days so as to lead to the answers to these questions. To demonstrate this, I will select a characteristic question that someone has posed. It was asked about the widespread popular notion that women during menstruation have a kind of withering effect on flowers nearby, particularly if they touch them. This notion has its basis in reality, though it has not been observed often enough and is therefore frequently overlooked. All you need to do is to take the view of the human being that we have developed here, and you will find the inner cause of this phenomenon. Just consider that what works in the flower and the formation of the blossom strives upward from the earth; in the human being, what corresponds to this blossoming force works from above downward. This is certainly a cosmological-organic polarity. You need only picture that this normal process striving upward in the blossoms of plants is the opposite of the human process working from above downward (see figure 5). There must be a balance, and this is present in the normal human being.

Now picture the forces from above downward intensified, which is what manifests during menstruation. Then you have an intensification of forces in the human being that work against the blossoming forces of plants. So you see how an understanding of the connection of these facts enables you, if you proceed in this way, to understand this remarkable relationship that finds expression in popular views surviving from ancient, instinctive perceptions.

Here is another question: “What can one do for a type of asthma that starts with cramp state and includes among its symptoms a surplus of blood below and a deficiency of blood above?” How do we treat this form of asthma? What is going on in such a case? In such a case, the nerve-sense process has slipped down into the breathing process. This is nothing other than an excessive activity within the breathing process, and clearly this excessive activity is due to the slipping down of the nerve-sense process. You must work against this polarically; you must approach from the other side. You must oppose what has entered from outer nature with forces that have the opposite direction. You call forth such forces when you introduce the acid process through the skin, that is, by giving carbonic acid baths or other acidic baths. These will be especially beneficial in asthmatic diseases of this type. If you keep in mind the other things I have spoken about, you will be led to use many other remedies as well.

Now, a question has been asked about milk injection in cases of excessive mucous discharge. This procedure has indeed caused tremendous astonishment and satisfaction in clinics. From what I have presented in these lectures about milk secretion you will readily see that in a large number of cases this treatment is connected with what I said. You need only recall what we said about the secretion of milk: that it is also a sense-process, but one that has slipped down deeper. I have already described the abnormalities that arise there. Now, directive forces remain, of course, in the secreted product. This is a process in which what has taken place within the organism continues. If you now inject a patient with milk, you can obviously work against a process that depends on fairly similar things. This is a case in which empirical chance has in fact worked in an extraordinarily ingenious way, for this treatment has only been discovered by chance, that is, by experimenting. It is generally of the greatest importance to look into the metamorphosis of a process. If a person cannot gain insight into how processes are metamorphosed, he will be unable to judge the simplest things correctly.

A question has surfaced about the causes of colds, of all those things designated by the somewhat diffuse concept of a “cold.” Here also a sense activity is displaced, pushed down into the breathing activity, but now in a different way from before. The secretions that arise are only reactions to this. This is something that takes place in the organism more toward the surface, something that continually takes place within the organism through the interaction of the nerve-sense activity and the metabolic activity. This is going on inside continually. You should not be surprised that these things are treated by the simplest methods, with poultices and the like, in which a kind of nerve-sense activity is inserted where otherwise it is not present. All poultices and so on push a nerve-sense activity into the organism, an activity that is half-conscious and otherwise would not be there.

I have also been asked how muscle forces are related to bone forces. Their relationship is such that the effects that have come to rest or are dying in bone forces are in full movement in muscle forces. Bones are simply transformed muscles, not in the genetic sense, but from the point of view of the idea. For this reason it is really absurd to look for a genetic connection between bones and muscles, or even between cartilage and bone. Many people have correctly drawn attention to the difficulty of finding a genetic connection here. Bunge, for instance, has pointed to this difficulty in finding a genetic connection between cartilage and bone, but he has not, of course, pointed to the source of this difficulty. It is due to the fact that there is a metamorphosis here. Just picture, however, the time when the whole muscle formation has not yet passed into the organic-visible sphere (see figure 6, red). This is also the case with cartilage formation, only much less so. Picture the time when the muscle and bone formation are still undifferentiated (see figure 6, light). When differentiation proceeds into this state of undifferentiation, these processes are subject at the same time to polarity, and it is naturally extraordinarily difficult to detect this metamorphosis. You can detect an outer, genetic metamorphosis only if, in the differentiation of one tissue from another, polarity does not have an essential effect during the transformation, but the original direction is maintained. When polarity immediately exerts influence on differentiation, quite another structure will naturally result, and this will no longer resemble the first.

We will address some of the other questions in the next lecture. There is however a question which I beg you to recognize as typical for questions which lead to a realm where confusion sets in strongly and where one ought to avoid drawing analogies. The question is whether one could construct something like a spectrum of taste, going from sweet through bitter, sour, chalky, to salty, and then also perhaps a spectrum of smell. There is so little objectivity regarding taste and smell, in fact, that it is especially useless to try to find analogies. Such things are of minor significance in practical application. On leaving the domain of the eye and ear and passing into the domain of taste and smell, we come into a totally different realm. In visual perceptions one has to do with revelations entirely from the etheric world, whereas in the processes of smell and taste one has to do with something involved very powerfully in material processes, in effects of substances, in metabolic processes. Thus in passing over to these sense activities, one can keep to the more robust processes that come to expression in metabolism.

Another question has been posed that deals with a significant principle: “Can a human being, without taking anything, produce out of himself bromine, morphine, iodine, quinine, arsenic, and other remedies?” This is a question that leads to very deep foundations of man's whole organization. One cannot produce the substances, but one can produce the processes. It can be said emphatically that one is, of course, quite unable to produce the substance ‘lead’ in oneself. However it is quite possible to produce the lead process in oneself from out of the etheric and then to let it radiate into the physical body. Here it may be asked whether it is not possible then to dilute a substance homeopathically to such a degree that by this process I try to work into the etheric body, calling forth this process of ‘self-metallization,’ of ‘self-radiation,’ that corresponds to a process of metallic radiation? In a certain sense this is absolutely possible, but it is a matter of advancing to the process of radiation that proceeds from the metallic element.

If you remain stuck in the allopathic way of thinking, you cannot approach these things, of course. You must think of them as follows: The radiating forces of magnesium are present in the process of tooth formation. These are forces that have a significance for the whole human organism, for the teeth are pushed out of the whole human being. You may use magnesium salt, any magnesium salt—magnesium sulphate, let us say—applying it in such a way that you put aside all allopathic approaches and prepare an especially strong dilution. Here we are led to the necessity of using quite high dilutions. You now have a twofold effect: you have first the effect of magnesium that basically stops where the teeth are. In the normal person the magnesium forces do not extend beyond this region. You must intensify them so that they extend their effect further, irradiating the whole human being. One can achieve this especially well by using the salt, magnesium sulphate, for this furthers the magnesium radiation even into the head forces. You allow it to radiate back from there. In fact, this process that proceeds from the etheric—remaining in the etheric by this homeopathizing process—is called forth where one has only the forces but not the substance, where one has proceeded from a totally different substance. You know, of course, that magnesium sulfate has been used empirically here, but one will only be able to use it rationally if this connection is borne in mind. It will then be noticed that one can depend on the sulfate only halfway; one must also depend on the magnesium for the other half, so that anyone who believes another sulfate would do as well will be making a mistake. This is the sort of thing that results if one proceeds from considerations that are supported only by the methods of the outer sense world and a combining intellect.

I would now like to point out briefly that all these matters that have been presented to you must be studied in the following way: In order to get behind the effects that must be observed, one must first select single features; then, however, one must see them again as a whole. With these lectures in particular, I am requiring you to exert yourselves to see things in their interrelationships. And now I would like to suggest how you might do this. I have been asked, for example, about exophthmalic goiter, Graves' disease. You may turn to what I explained in the first lecture on curative eurythmy, where I pointed out that the thyroid gland is a brain that has not attained completion. If you recall this and notice how the forces that act abnormally in Graves' disease tend toward the thyroid gland and, in doing so, produce all the other symptoms associated with Graves' disease, you will find how to work against it by measures that oppose this overly strong tendency of the human being to become a “head.” Here we are led to what is to occupy the next lecture. We are led to see that such conditions can really be opposed beneficially by significant movements, especially by significant movements associated with consonants. And you will achieve results in the initial stage of Graves' disease if you thoroughly apply what we have just spoken about in the curative eurythmy lecture. You see, in connecting all these things you must also look in that direction. We will not bring these studies to a close with these lectures but will continue with them another time. There is still one lecture remaining, however.

What I have to say to you today about eurythmy will require the aid of the findings of physiology and the like. How this should happen will no doubt become clear to you as a matter of fact in the course of your work. Precisely when investigating a bodily and spiritual process such as the one which occurs in doing eurythmy, we cannot do otherwise than point to deeper physical and spiritual connections.

To begin with, we will look at that extra-human cosmic process usually considered only with respect to its external details and not explored with respect to what is inwardly active. Just consider that “earth formation” means that a formative tendency is working in from the collective planetary sphere and that in addition a formative impulse into the earth emanates from what lies even beyond the planetary sphere, through continually in-streaming cosmic forces which manifest themselves in individual force entities on the earth.

We can come to understand these cosmic forces (this can also include everything which I previously said about radiations) by considering them as working towards the center and forming from outside what is on the earth and in the earth. It is, for example, a fact that the metals of the earth, in their entirety, are not primarily formed by forces inside the earth but are placed into the earth from out of the cosmos. These forces, which work through the ether (from the planetary sphere, not from the planets, for then they would be working centrally again—the planets are there to modify them) we can call formative forces, the formative forces working from outside. They encounter forces which in man and in the earth receive the formative forces, consolidate them and gather them around a center so that the earth can come into being. Thus we can call these forces the consolidating forces (see diagram).

They are present in man as forces which plastically shape the organs, whereas the other forces, the formative forces, push the organs, as it were, from the spiritual-etheric world into the physical world.

This is a process which, if I could say it this way, is almost palpable in the contrast between the pushing forces of magnesium and the forces of fluorine which round off. It is a process which can be found everywhere; in the teeth it occurs from below upwards, rounding itself above, and it also occurs from front to back and from back to front, and from above to below, rounding itself below. Again you can get an almost palpable comprehension of this process if you imagine that with the tendency to push something spherical towards the back, from outside towards the inside, something is formed there, and this is opposed by a sphere-forming process from below to above (see figure 2, red). Between these processes there is mediation by the secretory processes, including also the assimilation of what is secreted by other processes; in short, everything one can call secretory processes in the widest sense because, after all, assimilation depends on the reabsorption of something which is secreted towards the inside. Thus what is active in between can best be called secretory processes.

Again you can have a palpable comprehension of such a secretory process if you think that, on the one hand, something is present here which wants to continuously excrete carbon (see figure 3, orange) and that there is something else which assimilates it again in the formation of carbonic acid (white) through breathing from the front. Then such a secretory process continues behind it.

If you go still further down into the metabolic-limb process, you have a real consolidation process. However, this consolidation process is also present in the other direction. You can see it everywhere, and you can have a palpable experience, as it were, if you look at the eye. As embryology shows us, it is formed from outside towards the inside, and is consolidated from within; the formation is internalized. The development of the eye depends on this (see figure 4, orange). Then as we go on to the soul and spirit in man, and therefore to the organs of the soul and spirit, to the sense organs, we see this consolidation process spiritualizing itself—really ensouling and spiritualizing itself in perception. This, in a way, is the descending process which leads to the formation of organs (see figure 1). We find the perceptual process, or objective perception, at the lower end.

If this develops further, then perception goes back towards what is consolidating; if what is consolidating becomes conscious it becomes Imagination. If Imagination develops further and becomes conscious through the secretory process, it becomes Inspiration. And if Inspiration develops further towards the formative process and consciously encounters the formative process and thus understands formations, then it becomes Intuition. One can thus develop these stages of soul life from objective perception to Imagination, Inspiration and Intuition.

This process, developed in the soul, is based on the process of becoming, but as you can see (in figure 1), it is the reversal of the process of becoming. One goes towards what has become, and ascends into becoming again in the reverse direction. Forming goes in a descending direction. One climbs up in the reverse direction and goes towards becoming. So, what one develops as perception and cognitional forces in Imagination, Inspiration and Intuition always has a counter-effect in the creative forces which express themselves in the formative forces, the secretory and consolidation processes.

From this you will see that something is active in the human organism in a reverse direction in creating and becoming from what one gets into if one ascends in cognition. This will show you that it is true that in Imagination we come to the same forces which assert themselves—without our consciousness—in growth phenomena, in formative growth phenomena. If we ascend to Inspiration, we come to forces which inspire man from without and thoroughly shape him in breathing, and which weave themselves into the plastic-formative forces and elaborate them. And if we ascend to Intuition, we ascend to the active entity (Agens) which enters our plastic forms as substantial beingness from the outer world.

Thus you see that we are taking hold of man as he shapes himself out of the cosmos here, and if we use the findings which we have acquired in anatomy or physiology and illumine them with what is given us here, then we will begin to understand the organs and their functions. So this is an indication for the understanding of organs and their functions.

Those forces which continually work plastically on man, which normally shape him through, live, on the other hand, in the consonantal movements. These, as I said yesterday, call forth the unconscious forces of Imagination, namely a kind of streaming-through of the organism. Here you can see how consonantal eurythmy takes hold of deficient formative-plastic forces in man and leads them over into the correct formation.

One could observe a child and notice that the body form is either deficient or is proliferating too strongly. What does it mean that the form is proliferating too strongly? It means that the form is working centrifugally and making the head big, and because it is getting too big, it does not get around to permeating itself with forces of Imagination in the right way. So these forces need to be supplied; one lets the child do consonantal eurythmy.

There is a question here about “a two-year old boy with a large head who is apparently healthy otherwise, not hydrocephalic.”—In properly used consonantal eurythmy, you have an antidote to overcome this. This is where a thorough observation of deeper morphological aspects points precisely to a treatment with eurythmy.

Then there is “a 12-3/4-year old boy whose longitudinal growth is clearly retarded, with no organic findings, he has worms, is intelligent but easily becomes mentally fatigued.”—This is an extraordinarily interesting complex of symptoms which all point to insufficient unconscious forces of Imagination, and which indicate that the plastic organ forces are rampant because there are not enough inner, or soul-, plastic forces. The plastic forces of the soul are also the ones which destroy parasites; if they are insufficient, it is no wonder that he has worms. So the antidote is to let him do consonants in eurythmy.

These connections show you exactly where you have to intervene with eurythmy. Even when these symptoms occur in a somewhat concealed way, eurythmy can still have an extraordinarily favorable effect if, in addition, one deals with the matter in a material, therapeutic way.

Here is an interesting question which of course I will have to answer only in principle. If complications occur, they would have to be specifically considered, but, even if something else has to be added, what I have to say here is to the point.—“I have a 5-year old child as a patient who lost a lot of blood from a bullet wound; two years ago his joints started to get deformed. He also has signs and symptoms which later lead to chlorosis (iron deficiency anemia) and the like in adults. How could one deal with this therapeutically?”

Here you have joint deformation. This is a working outwards of plastic forces which cannot stay inside anymore, and which radiate outwards so that they leave man instead of working inside him. They are radiated back most effectively precisely through the use of consonantal eurythmy, for with it you summon the objectively effective Imaginations which offset deformities. In the future (the question already quite correctly points to this), people in general will increasingly tend to deformities in manifold ways because they will not be able to form a normal shape with the unconsciously active forces anymore. Man is becoming free, and eventually he will be free even with respect to shaping his own form; but then he will have to be able to do something with this freedom. Therefore, he has to go over to the creation of Imaginations, which always counteract deforming tendencies.

Here we have deficient objective Imagination, but one might also have to deal with deficient objective Inspiration, which manifests itself through (if I might be permitted to express it in this way) a ‘deforming’ of the rhythmic system. This deforming of the rhythmic system expresses itself especially where the objective Inspiration, which goes inwards, does not meet the circulation rhythm in the right way. And here one works in a normalizing way if one uses vowel eurythmy. This vowel eurythmy also works on inner irregularities but now not accompanied by morphological changes, just as consonantal eurythmy works on morphological deformities, or on tendencies to develop morphological deformities.

Earlier I said that it might be necessary to support something like this if it occurs in a particularly radical fashion, as in the deforming of joints which we just discussed. Then it is necessary to therapeutically assist this process of consonantal eurythmy which, through this Imagination, stimulates the inner breathing of the organs which go from outside to inside, and which are situated beyond the intestinal walls: the lungs, kidneys and liver. It is a fact that if one does consonantal eurythmy, then especially the back part of the head, lungs, liver and kidneys begin to sparkle and scintillate, which shows the soul and spirit reaction to what is done outwardly in the moving of consonants. The whole man becomes a shining being in these organs, and the movements made outwardly are always met by shining movements within. Especially with certain consonant movements a whole shining reproduction of the kidneys' secretion processes occurs; one gets a picture of the whole secreting process of the kidneys. This then works over into unconscious Imaginations, and the entire process is the same one I have described as being under the influence of cuprum; it is the same process.

Here is an occasion to draw the physicians' attention to the fact that there are people who have certain forms of illness. Yesterday, these forms of illness were brought towards me again in the form of extraordinarily admired colored drawings, and people asked whether they were particularly occult. Of course they are occult in a certain way, but it is extraordinarily difficult to talk to people about these matters because such wonderful drawings are actually objectively-fixed kidney-luminescence (Nierenleuchten), they are an objectively-fixed urine formation process. If this urinary process becomes a luminescent process in an abnormal way in certain pathologically disposed people—if a certain congestion of urinary secretion occurs (a purely metabolic disease) and if the kidneys then begin to shine, and if a particular introverted clairvoyance sets in—then they begin to draw furiously. This always turns out to be beautiful, at least in an external, formal sense. The applied colors are always beautiful. Of course, people are not satisfied if one tells them: you have really painted something very beautiful there—that is your congested urinary secretion.—I can assure you that obstructed urinary secretion and suppressed sexual desires, which may also bring about irregularities of the metabolism, may well be presented to you by mystically inclined personalities as deeply mystical drawings and paintings, but much that appears in the world in this way needs to be recognized as symptoms of just barely tolerable pathological human conditions.

You see, anthroposophically oriented spiritual science is not mysticism in the way many people understand this, because it does not delude itself about matters such as the ones just characterized. Rather, it investigates them and then people are offended. For example, they were already offended when I went so far in public lectures as to indicate (even though the artistic productions were poems and not drawings) that the beautiful poetry of Mechthild von Magdeburg or of St. Theresa are copies, or the inspirational reflexes, of processes which arise through restrained sexuality. Of course, people find it disagreeable if one describes a Mechthild on Magdeburg or a St. Theresa as personalities with a strong sexuality which they suppressed because it became too strong for them, and that their beautiful poetic creations were then the reaction to certain metabolic and circulatory processes arising from such a suppression. Seen from a higher point of view, this phenomenon leads deeply into the secrets of existence, but one must be able to elevate oneself to such a view.

One should have at least an inkling of these peculiar processes which light up as inner processes when one does eurythmy. If what is hidden in a poem is eurythmized, as I showed you yesterday, if a beautiful poem is read and eurythmy is done to it in an appropriate way with consonants or vowels, then this also is accompanied by something else—then an inner, silent speaking joins what is done there externally in the eurythmy movements. And, if the process is not sweltered out in sultry poems, but if the process simply accompanies beautiful poems eurythmically, then what takes place in people is not a representing of something mystical but is a process which definitely makes a person healthy. If one lets the patient do eurythmy by always telling him to pay attention to what he is hearing and to be strongly aware of the sound heard, and of the heard context of the sentence he is eurythmizing, one will then let him arise to the external formative forces, to the objective intuiting forces.

If one wants to work on what are called inborn errors, defects, etc. (which materialism calls heredity, but a large part of this was brought along from the pre-existent life of soul and spirit) then one will do well to work with eurythmy especially at a young age, by repeatedly challenging the person doing eurythmy to make very clear to himself what he is hearing outwardly. In this way one drives away all those tendencies which want to inwardly fix what may possibly want to arise into something like mystical drawings or poems. This focused listening while doing eurythmy is then attached to the outer, beautiful poem. It is a reverse process. A true mystic knows that there is always something questionable about a beautiful object which is a reflection of an abnormality. On the other hand, if what is beautiful in the outer world is inwardly experienced, one cannot say that it presents itself as a particularly great and beautiful figure; on the contrary, it becomes schematic and abstract in the way that a drawing is abstract. But precisely this is a healthy thing, this is what is desired. It is true that this beautiful, historical process would not have come about—but if, for example, Mechthild von Magdeburg had been induced to do eurythmy to some good poems, she would have been protected from her whole mystical destiny. Of course, when one gets to this point, one arrives where good and evil cease to be. One comes to the amoral Nietzsche sphere beyond good and evil, and of course one should not be narrow-minded and say that all Mechthild von Magdeburgs should be destroyed, bones and all. On the other hand, you can be sure that it is well taken care of from the spiritual worlds, that, even though man does not let these things proliferate, the appropriate connections with the super-sensible world nevertheless remain.

Even though the hour is late, I would like to go into a few things which might clarify the following question:—“Could therapeutic eurythmy exercises be supported by rational breathing exercises? It does not have to be Hatha Yoga right away.”—Rational breathing exercises to supplement eurythmy exercises for present human nature, which is developing as it is today, can only be treated in the following way; one will notice that, under the influence of vowel eurythmy, a tendency to change the breathing rhythm occurs by itself. This one will notice. Then one is faced with the difficulty of not forming mental stereotypes or saying anything in general, but of first observing to come to insight about what should be done.

In a single individual case where one wants to help to heal with vowel eurythmy in accordance with other findings one should observe the breathing, the change in breathing, and then draw the patient's attention to it so that he consciously continues this tendency. For, unlike the old orientals, we can no longer take the reverse path and influence the whole man through prescribed breathing. This is something which under all circumstances leads to inner shocks, whether it is prescribed in this or that way, and it should be avoided. We must learn to observe what vowel eurythmy teaches us about its influence on the breathing process. Then we can consciously continue what appears eurythmically in the individual case. From this you will see that the breathing process is continued in a specifically individual way—that is, differently in different people.

So this, my esteemed friends, is about all that could still be answered. There are a few things we cannot get to because of a lack of time. In conclusion, my dear friends, I would briefly like to tell you that you will have to be prepared for the battle which will proceed just as much from your medical colleagues in the world, once they become strongly aware that some of our kind of thinking is asserting itself, and you will certainly need a strong power of conviction to paralyze what will come to meet you. Of course, opposition should never make one stop doing things, but we should also have no illusions about all the antagonistic forces which will be stirred up.

At the end of this course I would again like to say that to make the movement which is now to be inaugurated in the medical field possible, I will everywhere strictly adhere to the principle of not directly intervening in the healing processes of patients and will only advise the physicians themselves, so that you will always be in a position to reject suggestions that I myself have entered into the doctor-patient relationship in perhaps an unjustified manner. I already said this at the end of the last course. One should not remain silent about the fact that this is made extraordinarily difficult from anthroposophical quarters because, of course, people come with all kinds of unreasonable demands in this respect. It is also definitely the case that there is a tendency among anthroposophists not to get beyond their egotism but to sometimes get even more egotistical than normal people, and in some cases, they become highly indifferent to the well-being of the movement and to the fact that the well-being of the movement depends on not practicing what the outer world calls quackery. For a healing process of all of medicine should occur, and it should not be disturbed by the demands which individuals sometimes make because of their personal aspirations. This becomes very difficult, but it has to be done along these lines. We will succeed in this area only if in reply to false accusations from the outer world we can say: what is said there is definitely a lie, it is definitely made up. We will be able to say this simply because we know what is going on in the anthroposophical movement. In certain cases we will simply always have to be able to say this. However, we can only say this if we are inwardly initiated into everything which consists of such things as the ones to which I have drawn your attention here, namely that I will not directly intervene in therapy, but that the people who function as physicians within our anthroposophical movement are there to heal the patients.

In conclusion I would like to express to you my hope that these beginning impulses, although still mere indications, may be developed further by you, and that they become effective for the well-being of mankind. Hopefully we will have an opportunity to continue what we have now begun twice, and will at least make an effort to continue this in some way. With this wish I close these contemplations, my dear friends, and I hope that our deeds will correspond to our wishes in all these directions. It was very satisfying to see you here. It will be satisfying to think back to the days which you wanted to stay here, precisely for the enrichment of medical science, and the thoughts which shall hold us together will accompany you on the paths, my dear friends, on which you will walk to transform into deed what to begin with we tried to stimulate here in thoughts.

I must ask my audience to be considerate with me to-day, because I have only just arrived after a very tiring journey and shall probably not feel able to speak to you adequately until tomorrow.

I want this first lecture to be a kind of introduction to the series I am to deliver here. I had not really intended to speak during the Conference, because I think the stimulus given by anthroposophical research to medicine and to scientific thought ought to be worked out by those who are specialists in the various domains. Indeed, all that comes from anthroposophical investigation in regard to medicine and, for instance, physiology, can be nothing more than a stimulus which must then be worked out empirically. Only on the basis of this empirical study can there arise valid and convincing judgments of the matters in question—and this is the kind of judgment that is needed in the domain of therapy.

These lectures, however, are given at the request of doctors who are working with us and I shall try to deal with just those points where Anthroposophy can throw light into the realm of medicine. I shall endeavour to show, first of all, that an understanding of the human being in health and disease can be enriched and deepened through anthroposophical conceptions.

By way of introduction, I may perhaps be permitted to speak of the sense in which the anthroposophical mode of thought should be understood to-day, in our own age. People so readily confuse what is here called Anthroposophy with older traditional ideas. I have no wish to waste words about the value of these old conceptions, or to criticise them in any way. But it must be emphasised that the conceptions put forward by me are founded on a basis quite different from that of the various mystical, theosophical and so-called gnostic ideas which have arisen traditionally in the course of human history. In order to make myself clear, I need mention only the main points of difference between the conceptions which will be put forward here and those of earlier times. Those earlier conceptions arose in human thought at a time when there was no science in our sense; mine have been developed in an age when science has not only come into being but has reached a certain—albeit provisional—perfection. This must always be remembered if we would understand the meaning and significance of our studies, for it applies to all that may be said and discovered by Anthroposophy in regard to the different domains of human knowledge and capacity.

You all know—there is no need to enlarge upon it—that in those earlier times man had a real but non-scientific conception of the super-sensible world. Medicine, too, was permeated with conceptions of the human being that did not originate, as is the case to-day, from empirical research. We need go back only to the age shortly before that of Galen, and, if we are open-minded enough, we shall everywhere find traces of spiritual conceptions of the being of man on which medical thought, too, was based. Permeating these conceptions of the form of man, of his organs and organic functions, were thoughts of the Supersensible. According to the modern empirical way of thinking, there are no grounds for connecting anything super-sensible with the nature and constitution of man, but in those older conceptions the super-sensible was as much a part of man as colours, forms and inorganic forces now seem to us part and parcel of the objects in the outer world.

Only prejudice will speak of those earlier ages in the development of medicine as if its ideas were merely childish, compared with those that have been evolved to-day. Nothing could be more inadequate than what history has to tell in this connection, and anyone who has the slightest understanding of the historical evolution of mankind, who does not take the point of view that perfection has been reached and that everything earlier is mere foolishness, will realise that even now we have arrived only at relative perfection and that there is no need to look back upon what went before with a supercilious eye. Indeed, this is patent when we consider the results that were achieved. On the other hand, a man concerned with any branch of knowledge to-day must never overlook all that science has accomplished for humanity in this age. And when—to use the Goethean expression—a spiritual conception of the human being in sickness and health strives to express itself to-day, it must work with and not against modern scientific research.

After what I have said, you will not accuse me of any desire to rail against the concepts of modern science. Indeed, I must emphasise at the outset that such a thing is out of the question and for a very fundamental reason. When we consider the medical views that were held in an earlier period of civilisation, we find that although they were by no means so childish as many people imagine nowadays, they did lack what modern science has been able to give us, for the simple reason that man's faculty of cognition was not then adapted to the study of objects as we approach them with modern empirical thought, which is assisted, moreover, by all kinds of scientific instruments. The doctor, or I might just as well say the physiologist or biologist of olden times, had an entirely different outlook from the outlook of modern man. In the ages that really came to an end with Galen, medical consciousness had quite another orientation. What Galen saw in his four elements of the human organism, in the black and yellow gall, in the phlegm and in the blood, was utterly different from the modern conception.

When Galen describes all this and we understand the terminology—as a rule, of course, words handed down by tradition are not understood—we get the impression of something vague and nebulous. To Galen, it was a reality; in what he called phlegm he did not see the substance we call phlegm. To him, phlegm was not only a state of fluidity permeated with life, but a state of fluidity permeated with soul. This was as clear a perception to him as our perception of the red or blue colour of some object in front of us. But precisely because he was able to perceive something outside the range of modern scientific perception, Galen was not able to see many things that are brought to light to-day by our scientific consciousness. Suppose, for example, a man with not so very abnormal sight looks through spectacles, and by this means the contours of objects become more definite. As the result of modern empiricism, all that was once seen in a cloud, but none the less permeated by Spirit and soul, has disappeared and given place to the sharp contours of empirical observation. The sharp contours were not there in olden times. Healings were performed out of a kind of instinct which was bound up with a highly developed sensitiveness to one's fellow-men. A sort of participation in the patient's disease, which could even be painful, arose in the doctor of olden times, and on the basis of this he set about his cure.

Now for the reason that the advance to objective empiricism is rooted in the evolutionary process of man, we cannot merely brush it aside and return to the old. Only if we develop certain atavistic faculties shall we perceive Nature as the ancients perceived her, in all domains of knowledge, including that of medicine. When we pass out into modern culture, equipped with the kind of training given in our elementary schools—not to speak of higher education—it is simply impossible to see things as the ancients saw them. It is impossible, and moreover, if such a thing were to happen, a man would be regarded as being if not gravely, at any rate mildly pathological, not quite ‘normal’—and, indeed, not altogether unjustly. For there is something pathological to-day in all instinctive ‘clairvoyance,’ as it is called. Upon that point we must be quite clear. But what lies in our power is to work our way up to a perception of the spiritual by developing inner faculties otherwise latent in our being, just as in the course of generations the eye has worked itself up from indefinite vision to clear, concrete vision.

To-day, then, it is possible to develop faculties of spiritual perception. I have described this development in my book, Knowledge of the Higher Worlds and How to Attain It, and in other writings. When these faculties have developed in a man he perceives, to begin with, a world not previously visible to him, a world embracing a spiritual Cosmos as well as the Cosmos revealed to sense-perception to-day, including all the discoveries and calculations of astronomy. To the material Cosmos that is permeated with natural law, a spiritual Cosmos is added. And when we seek to discover what exists in this spiritual Cosmos, we also find man. We contact a spiritual universe, a universe permeated with soul, where man has his rightful place.

If we pursue ordinary science, we begin either with the simplest living being or with the simplest form of life—the cell—and then trace the simple on into the more complex, ascending thus from what most resembles purely physically organised substance to the highly intricate organism of man. If we seriously pursue Spiritual Science, we begin really at the other end. We descend from a comprehension of the spiritual in the universe, regarding this as complex, and the cell as the simplest thing in the organism. Viewed in the light of Spiritual Science, the universe is the summit of complexity, and just as we elaborate our own act of cognition in order, let us say, to pass from the cell to the human being, so do we progressively simplify what the Cosmos reveals and then come to man. We go an opposite way—that is to say, we begin at exactly the opposite starting-point—but when to-day we thus pursue Spiritual Science, we are not led all the way into the regions embraced by material empiricism. I lay great stress upon this point and hope there will be no misunderstanding. That is why I must ask you to-day to forgive certain pedantic ideas.

It is quite conceivable that someone might think it useless to adopt the methods of empirical thought in physiology or biology. What need is there for any specialised branch of science?—he might ask. One develops spiritual sight, looks into the spiritual world, arrives at a conception of man, of the being of man in health and disease, and then it is possible to found a kind of spiritualised medicine. As a matter of fact that is just the kind of thing many people do, but it leads nowhere. They abuse empirical medicine but they are, after all, abusing something which they do not understand in the very least. There can be no question of writing off empirical science as worthless and taking refuge in a spiritualised science brought down from the clouds. That is quite the wrong attitude to adopt.

Now it must be remembered that spiritual-scientific investigation does not lead to the same things that can be examined under the microscope. If anyone tries to pretend that with the methods of Spiritual Science he has found exactly the same things as he finds under a microscope, he may safely be summed up as a charlatan. The results of modern empirical investigation are there and must be reckoned with. Those who seriously pursue Spiritual Science must concern themselves with the phenomena of the world in the sense of ordinary empiricism. From Spiritual Science we discover certain guiding lines for empirical research, certain ruling principles, showing us, for instance, that what exists at some particular place in the organism, must also be studied in reference to its position.

Many people will say: ‘Yes, but a cell is a cell, and purely empirical observation must determine the distinguishing feature of this cell—whether it is a liver-cell or a brain-cell and so on.’ Now that is not correct. Suppose, for example, I walk past a Bank at 9 o'clock in the morning and see two men sitting there side by side. I look at them and form certain ideas about them. At 3 o'clock in the afternoon it happens that I again walk past the Bank. There are the two men, sitting just as before. The empirical state of affairs is exactly the same—allowing for very slight differences. But now, think of it: one of the men may have remained sitting there for the whole six hours. The other may have been sent out on quite a journey directly after I first passed the Bank, and may have only just returned. This changes the picture fundamentally and has nothing to do with what I actually perceive with my senses. So far as my senses are concerned, the same state of things presents itself at 9 o'clock in the morning and 3 o'clock in the afternoon, but the objective fact must be judged from its connections, its attendant circumstances.

In this sense our conception of a liver-cell must differ essentially from our conception of a cell in the brain or the blood. For only if it were correct to say, for the sake of example, that the basis of everything is a primeval germ-cell which has been fertilised and that the whole organism can be explained by a process of simple fission and differentiation of this primeval germ-cell—only then could we proceed to treat a liver-cell exactly the same as a brain-cell in accordance with the purely empirical facts. Yes, but now suppose that this is by no means correct; that by virtue of its very position in the organism the relation of a liver-cell to forces outside man, outside the bounds of the skin, is not at all the same as the relation of a brain-cell to these forces. In that case it will not be correct to look on what is happening merely as a continuation of the process of fission and subsequent location in the body. We must rather assume that the relation of the brain-cell to the universe outside is quite different from that of the liver-cell.

Suppose a man looks at the needle of a compass, finds it pointing from South to North, from North to South, and then decides that the forces which set the needle in this direction lie in the needle itself. He would certainly not be considered a physicist to-day. A physicist brings the needle of the compass into connection with what is called terrestrial magnetism. No matter what theories may be evolved, it is simply impossible to attribute the direction of the needle to forces lying within the needle itself. It must be brought into relation with the universe.

In the study of organic life to-day, its relations to the universe are usually regarded as quite secondary. But suppose it were indeed true that merely on account of their different positions the liver and the brain are actually related quite differently to cosmic forces outside man. In that case we could never arrive at an explanation of the being of man by way of purely empirical thought. An explanation is possible only if we are able to say what part the whole universe plays in the moulding of the brain and again of the liver, in the same sense as the Earth plays its part in the direction taken by the needle in the compass.

Suppose we are tracing back the stream of heredity. We go to the forefathers, pass on to the present generation and then to the progeny, both in the case of animals and of human beings. We take account of what we find—as naturally we must—but we reckon merely with processes observed to lie immediately within the human being. It hardly ever occurs to us to ask whether under certain conditions it is possible for cosmic forces to work in the most varied ways upon the fertilised germ. Neither do we ask: Is it perhaps, impossible to explain the formation of the fertilised germ-cell if we remain within the confines of the human being himself? Must we not relate this germ-cell to the whole universe? In orthodox science to-day, the forces that work in from the Cosmos are secondary. To a certain limited extent they are taken into consideration, but they are always secondary. And now you may say: ‘Yes, but modern science leads us to a point where such questions no longer arise. It is antiquated to relate the human organs to the Cosmos!’ In the way in which this is often done, it is antiquated. The fact that as a rule such questions do not arise to-day is due entirely to our scientific education. Our education in science confines us to this purely objective and empirical mode of research, and we never come to the point of raising such questions as I have indicated by way of introduction. But the extent to which man is able to advance in knowledge and action in every sphere of life depends upon the raising of questions. If questions never arise, it means that a man is living in a kind of fog. He himself is dimming his free outlook upon reality, and it is only when things will no longer fit into his scheme of thought that he begins to realise the limitations of his conceptions.

Now I think that in the domain of modern medicine there may be a feeling that the processes taking place in the being of man are not wholly reconcilable with the simple, straightforward theories upon which most cures are based. There is a certain feeling that it must somehow be possible to approach the whole subject from another angle. And I think that what I shall have to say in this connection will mean something to those who are specialists in their particular branches of science, who have practical experience of the processes of health and disease and have realised that current conceptions and theories are too limited to grapple with the intricate organism of man.

Let us be quite honest with ourselves. During the nineteenth century a kind of axiom was put forward by nearly every branch of scientific thought. With a persistence that was enough to drive one to despair, it was constantly being said: ‘Explanations must be absolutely simple.’ And indeed they were! Yes, but if facts and processes are complicated it is prejudging the issue to say that the explanations must be simple. The thing is to accustom ourselves to deal with their complexities. Unspeakable harm has been done in the realms of science and art by the insistent demand for simplification. In all her manifestations, small and great, Nature is highly complicated, never simple. We can really grapple with Nature only if we realise from the outset that the most seemingly comprehensive ideas are related to the reality just as photographs of a tree, taken from one side only, are related to the tree. I can photograph the tree from every side and the photographs may be very different. The more photographs I have, the more nearly will my idea approximate to the reality of the tree.

The prevalent opinion to-day is this: such and such a theory is correct. Therefore some other theory—one with which we do not happen to agree—must be wrong. But that is just as if a man were to photograph a tree from one side only. He has his particular photograph. Somebody else takes a photograph from another side and says to the first man: ‘Your photograph is absolutely false; mine, and mine alone, represents the truth. In short, my particular view is correct.’ All controversies about materialism, idealism, realism and the like, have really taken this form. They are by no means dissimilar to the seemingly trivial example I have given. At the very outset of our studies I ask you not to take what I have to say as if it were meant to tend in the direction of materialism, idealism, or mysticism, but merely as an attempt to go straight for reality to the extent which the capacity of human thought permits. Materialistic conceptions often achieve great results when it is a question of mastering reality, but the spiritual aspect must be introduced as well. If it is impossible to keep the various aspects separate, our ideas will appear rather as if one took many different photographs all on the same plate. Indeed, many things are like this to-day. It is as if photographs from many different aspects had been taken on one plate.

Now when the forces lying latent in the soul of man are energised by the methods outlined in my book Knowledge of the Higher Worlds, we rise above the ordinary condition of knowledge—to which the latest phase in biology pays special devotion—and reach what I have described as Imaginative Cognition. A still higher level is that of ‘Knowledge by Inspiration,’ and the highest—if I may use this expression—is that of true Intuition, Intuitive Knowledge. In Imaginative Knowledge one comes to pictures of reality, knowing very well that they are pictures, but also that they are pictures of reality, and not merely dream-pictures. The pictures arising in Imaginative Cognition are true pictures but not the reality itself. At the stage of Knowledge by Inspiration reality begins to stream into these pictures, something lives within them; they tell us more than the picture alone. They themselves bear witness to a spiritual reality. And in acts of Intuitive Knowledge we live within the spiritual reality itself.—These are the three stages described in Knowledge of the Higher Worlds.

Now these three modes of higher knowledge give us, to begin with, an understanding of spiritual worlds, of a spiritual universe and of man as a being of Spirit and soul; they do not, in the early stages, reveal to us the findings of empirical research in the realm, say of, biology. When Imagination, or Inspiration, or Intuition, is used for gaining understanding of the being of man, a different way is followed.

Take, for instance, the structure of the human brain. It does not perhaps strike physiologists and doctors as very extraordinary, but to those who call themselves psychologists it is remarkable in the extreme. Psychologists are a strange phenomenon in our civilisation because they have managed to develop a science without subject-matter—a psychology without a soul! Think for a moment of a psychologist who takes his start purely from empirical science. In recent times people have really been at a loss to know what to make of philosophy, because it has been impossible to know whether philosophers know anything or not. Scientists, however, are supposed to know something, and so certain scientists who dabble in philosophy have been given Chairs of Philosophy. Current opinion has been this: the scientists must have some knowledge, because although it is quite possible in philosophy to talk round and round a subject, it is not possible in science to talk hot air about something that has been observed under a microscope, through a telescope, or by means of Röntgen rays. All these things can be tested and proved, but in philosophy it is not so easy to prove whether or not a man is talking out of the clouds.

And now, think of how Theodor Ziehen speaks of the structure of the brain. In this connection I once had a very interesting experience, and perhaps I can make the point more concrete by telling you a certain anecdote. Many years ago I once attended a meeting where an eminent doctor was speaking about the structure of the brain. He analysed the structure of the brain in relation to the soul-life of man from a point of view which might justly be called materialistic. He was an out-and-out materialist, one who had analysed the structure of the brain quite well to the extent to which it has been investigated in our times, and he then proceeded to explain the life of soul in connection with the brain and its structure. The chairman of the meeting was a follower of Herbart, and he, therefore, was not concerned with analysing the structure of the brain but the life of conception and ideation, as Herbart, the philosopher, had once done. He—the chairman—then said the following: ‘Here we have something very remarkable. The physiologist or the doctor makes diagrams and figures of the structure of the brain. If I, as a Herbartian, make drawings of the complicated associations of ideas—I mean a picture of the ideas which associate and not of the nerve fibres connecting one nerve-cell with another—if I, as a genuine Herbartian who does not concern himself with the brain as a structure, make symbolic diagrams of what I conceive to be the process underlying the concatenation of ideas, my drawings look exactly the same as the physiologist's sketches of the structure of the brain!’

This comparison is not unjustified. Science has taught us more and more about the structure of the brain. It has been proved in ever greater measure that the physical structure of the brain does, indeed, correspond in a marvelous way with the organisation of our life of ideation. Everything in the life of ideation can be found again in the structure of the brain. It is as if Nature herself had intended to create in the brain a plastic image of man's life of ideation. Something of the kind strikes us forcibly when we read statements like those of Meynert—nowadays they are already considered rather out-of-date. Meynert was a materialist, but an excellent brain-physiologist and psychologist. What he, as a materialist, tells us is a wonderful contribution to what is discovered when the actual brain is left out of account and we deal only with the way in which ideas unite, separate, etc., and then draw figures and diagrams. In short, if anything could make a man a materialist it is the structure of the human brain. At all events this much must be admitted: If, indeed, the Spirit and soul exist, they have in the human brain so perfect an expression that one is almost tempted to ask why the Spirit and soul in themselves are necessary for the life of ideation, even if people still hanker after a soul that can at least think. The brain is such a true mirror-image of the Spirit and soul—why should the brain itself not be able to think?

All these things must of course be taken with reservations. To-day I only want to indicate the tenor of our studies as a whole. The human brain, especially when we begin to make detailed research, is well calculated to make us materialists. The mystery that really underlies all this clears up only when we reach the stage of Imaginative Knowledge, where pictures arise—pictures of the spiritual world not previously visible. The pictures actually remind us of the configurations in the human brain formed by the nerve-fibres and nerve-cells.

What, then, is this Imaginative Knowledge, which functions, of course, entirely in the super-sensible world? If I were to attempt to give you a concrete picture of what Imaginative Knowledge is, in the way that a mathematician uses figures to illustrate a mathematical problem, I should say the following: Imagine that a man, living in the world, knows more than sense-cognition can tell him because he can rise to a world of pictures which express a reality, just as the human brain expresses the life of soul. In the brain, Nature has given us as a real Imagination, an Imagination that is real in the concrete sense, something that is attained in Imaginative Knowledge at a higher level.

This, you see, leads us more deeply into the mysteries of the constitution of man. As we shall find later on, this marvelous structure of the human brain is not an isolated formation. Through Imagination we behold a super-sensible world, and it is as though a part of this world had become real in a lower world; in the human brain a world of Imagination lies there, in concrete fact, before us. I do not believe that anyone can speak adequately about the human brain unless he sees in its structure an Imaginative replica of the life of soul. It is just this that leads us into difficulties when we take our start from ordinary brain-physiology and try to pass to an understanding of the life of soul. If we confine ourselves to the brain itself, a life of soul over and above this does not seem to be necessary. The only persons with a right to speak of a life of soul over and above the brain are those who have a knowledge of it other than that which is acquired by customary methods. For when, in the act of spiritual knowledge, we come to know this life of soul, we realise that it has its complete reflection in the structure of the human brain, and that the brain, moreover, can do everything that the super-sensible organ of soul can do by way of conceptual activity. Down to its very functions the brain is a mirror-image. With brain-physiology, therefore, no one can prove or disprove materialism. It simply cannot be done. If man were merely a being of brain, he would never need to say to himself: ‘Over and above this brain of mine, I possess a soul.’

In contrast to this—and I shall now describe in an introductory way something that will be developed in the subsequent lectures—let us consider a different function of the human organism, not the life of ideation, but the process or function of breathing. Think of the breathing process and of what passes into consciousness with regard to it. When we say to ourselves: ‘I have an idea which reminds me of another idea I had three years ago and I link the one to the other’—we may well be able to make diagrams, especially if we take a series of ideas. Such diagrams will bear a great resemblance, for instance, to Meynert's sketches of the structure of the brain. Now this cannot be done when we try to find an expression in the organism of man of what is contained in the breathing-processes. We can find no adequate expression of the breathing process in the structures and formations of the physical organs. The breathing process is something for which there is no adequate expression in the human organism, in the same sense as the structure of the brain is an adequate expression for the life of ideation and perception.

In Imaginative Knowledge pictures arise before us, but if we rise to knowledge by Inspiration, reality streams through the pictures from behind, as it were. If, then, we rise to Inspiration and gaze into the super-sensible world in such a way that the Imaginations teem with spiritual reality, we suddenly find ourselves standing in a super-sensible process which has its complete analogy in the connection between the breathing process, the structure of lungs and arachnoidal cavity, central canal of the spinal cord and the continuous flow of the breath into the brain. In short, if we rise to Inspiration, we learn to understand the whole meaning of the breathing process, just as Imaginative Knowledge leads to an understanding of the structure of the brain. The brain is an Imagination made concrete; everything connected with the breathing process is an Inspiration made real, an Inspiration brought down into the world of sense. A man who strives to reach the stage of Knowledge by Inspiration enters a world of Spirit and soul, but this world lies there tangibly before him when he observes the whole breathing process and its significance in the human organism.

Imaginative Knowledge, then, is necessary to an understanding of the structure of the brain; Knowledge by Inspiration is necessary before we can understand the rhythm of breathing and everything connected with it. The relation of the breathing process to the Cosmos is quite different from that of the brain. The outer, plastic structure of the brain is so completely a mirror-image of the Spiritual that it is possible to understand this structure without penetrating very deeply into the super-sensible world. Indeed, we need only rise to Imagination, which lies quite near the boundaries of ordinary cognition. The breathing process cannot be understood by means of Imagination; here we must have Inspiration, we must rise higher in the super-sensible world.

To understand the metabolic process we must rise higher still. The metabolic process is really the most mysterious of all processes in the human being. The following lectures will show that we must think of the metabolic process quite differently from the way in which it is thought of in empirical physiology. The changes undergone by the substances as they pass from the tongue to the point where they bring about something in the brain cells, for instance, cannot, unfortunately, be followed by means of purely empirical research, but only by means of Intuition. Intuition leads us beyond the mere perception of the object into the very object itself. In the brain, the Spirit and soul create for themselves an actual mirror-image, but they remain, in essence, outside this image. As Spirit and soul they influence and pass into the breath-rhythm but constantly withdraw. In the metabolism, however, the Spirit and soul submerge themselves completely; as Spirit and soul they disappear in the actual process. They are not to be found—neither are they to be found by empirical research.

And now think of Theodor Ziehen's subtle descriptions of the structure of the human brain. It is, indeed, also possible to make symbolic pictures of the memory in such a way that the existence in the brain of physiological-anatomical mirror-images of the faculty of memory can be proved. But when Ziehen comes to the sentient processes, there is already a hitch, and that is why he does not speak of feelings as independent entities, but only of mental conceptions coloured with feeling. And of the will, modern physiologists have ceased to speak I Why? Very naturally they say nothing. Now when I want to raise my arm—that is to say, to accomplish an act of will—I have, first of all, the idea. Something then descends into the region that, according to current opinion, is wholly ‘unconscious.’ Everything that cannot be actually observed in the life of soul, but is none the less believed to be there, is thrown into the reservoir of the ‘unconscious.’ And then I observe how I move my hand. Between the intention and the accomplished fact lies the will, which plays right down into the material nature of the physical organism.

This process can be followed in detail by Intuitive Knowledge; the will passes down into the innermost being of the organism. The act of will enters right into the metabolism. There is no act of will performed by physical man which cannot be traced by Intuitive Knowledge to a corresponding metabolic process. Nor is there any process of will which does not find its expression in demolition, dissolution—call it what you will—within the metabolic processes. The will first demolishes what exists somewhere or other in the organism, in order that it may act. It is just as if I had to burn up something in my arm before being able to use this limb for the expression of my will. Something must first be done away with, as we shall see in the following lectures.

I know that this would be considered a fearful heresy in science to-day, but nevertheless it will reveal itself to us as a truth. Something that is of the nature of substance must be destroyed before the will can come into play. Spirit and soul must establish themselves where substance existed. Understanding of this belongs to the very essence of Intuitive Knowledge, and we shall never be able to explain the metabolic processes in the human being unless we investigate them by its means.

These three processes—the nerve-sensory process, the rhythmic processes (breathing and blood circulation) and the metabolic processes—include, fundamentally speaking, every function in the human organism. Man is really objective knowledge, knowledge made actual—no matter whether we merely observe him from outside or dissect him. Take the human head. We understand what is going on in the head when we realise that there is such a thing as Imaginative Knowledge; the processes in the rhythmic system become clear when we know of the existence of Knowledge by Inspiration; we understand the metabolic processes when we know of the existence of Intuition. Thus do the principles of reality interpenetrate in the being of man. Take, for example, the specific organs of the will—they can be understood only by an act of Intuitive Knowledge.

As long as we apply a rigidly objective mode of cognition to the being of man, we shall not realise that he is, in fact, not at all as he is usually supposed to be. Modern physiology knows, of course, that to a great extent the human being is a column of fluid. But now ask yourselves quite honestly whether physiology does in fact reckon with man as a column of fluid, or whether it does not proceed merely as if he were a being consisting of solid forms. You will probably have to admit that little account is taken of the fact that he is essentially a fluidic being and that the solids have merely been inserted into this fluid. But, as a matter of fact, man is also an airy, gaseous being, and a being of warmth as well. The solid part of man can well be understood by means of ordinary objective cognition. Just as in the laboratory I can become familiar with the nature of sulphide of mercury, so by chemical and physical investigation of the human organism I can acquaint myself with all that is solid. It is different with the fluids in the being of man. The fluids live in a state of perpetual integration and disintegration and cannot be observed in the same way as the stomach or heart are observed and then drawn. If I make drawings of these organs as if they were solid objects, a great deal can be said about them. But it is not the same if we take this watery being of man as something real. In the fluids something is always coming into being and disappearing again. It is as if we were to conceive of the heart as continually coming into being and disappearing—although the process there is not a very rapid one. The watery being of man must be approached with Imaginative Knowledge.

The importance of the organic functions in the human organism, and their connection with the circulation, are of course well known, but how these functions play into one another—that follows precisely the pattern of Inspiration. Only through Inspiration can the airy part of man be understood.

And now let us pass to the warmth in the human being. Try to realise that man is something very special by virtue of the fact that he is a being of warmth; that in the most various parts of his structure warmth and cold are found present in the most manifold ways. Before we can realise how the Ego lives in the warmth in man, we must ourselves live in the process. There must be an act of Intuitive Knowledge.

Before man can be known in his whole being—not as if he were simply a mass of solid organs with sharp contours—we must penetrate into the organism from many different angles. Just as we feel the need to exercise Imagination, Inspiration and Intuition as we pass from the brain to the other organic phenomena, so it is when we study the aggregate states of matter within him. The solid part of man, his solid bodily nature, hardly differs at all from the state in which substances exist outside the human organism. There is an essential difference in the case of the fluids and gases, and above all in the case of the warmth. This will have to be considered in the next lecture. But it is, indeed, a fact that only when our observation of man widens out in this way do we realise the full significance of the organs and systems of organs.

Empirical physiology hardly enables us to follow up the functions of the human organism further than the point where the chyle passes from the intestines into the lymphatic vessels. What follows is merely a matter of conjecture. All ideas about the subsequent processes in the substances we take in from the outside world, for instance the processes in the blood stream, are really nothing but fantasy on the part of modern physiology. The part played by the kidneys in the organism can be understood only if we observe the katabolic processes side by side with the anabolic processes, which today are almost invariably regarded as the only processes of significance. A long time ago I once said to a friend: ‘It is just as important to study those organs which are grouped around the germ of the human embryo, and which are later discarded, as to study the development of the germ itself from conception to birth.’ The picture is complete only when we observe the division of the cells and the structure arising from this, and also trace the katabolic processes which take their course side by side with the anabolic processes. For we not only have this katabolic process around us in the embryonic period; we bear it within us continually in later life. And we must know in the case of each single organ, to what extent it contains anabolic and to what extent katabolic processes. The latter are, as a general rule, bound up with an increase of consciousness. Clear consciousness is dependent on katabolic processes, on the demolition of matter.

The same must be said of the excretory processes. The kidneys are organs of excretion. But now the question arises: Although from the point of view of material empiricism the kidneys are primarily excretory organs, have they no other purpose in the constitution of man beyond this? Do they not, perhaps, play a more important part in building up the human being virtue of something other than their excretory functions? If we then follow the functions still further, passing from the kidneys to the liver, for example, we find this interesting phenomenon:—The kidneys secrete in the last resort, outwards; the liver, inwards. And the question arises: How is the relation of the kidney process to the liver process affected by the fact that the kidneys send their excretory products outwards and the liver inwards? Is the human being at one time communing, as it were, with the outer world and at another with himself?

Thus we are led gradually to penetrate the mysteries of the human organism, but we must bring to our aid matters that are approached in the ways of which I have to-day given only preliminary hints. I will proceed from this point in the following lectures, showing how these things lead to a true understanding of pathology and therapy, and how far they may become guiding principles in orthodox empirical research. No attack on this kind of research is implied. The only object is to show that guiding principles are necessary.

I am not out to attack scientific research or scientific medicine in any sense. My aim is to show that in this scientific medicine there is a mine of opportunity for a much wider knowledge than can be attained by modern methods, and above all by the current outlook on the world.~ We have no wish to scoff at the scientific mode of observation but on the contrary to give it a true foundation. When it is founded upon the Spirit, then, and only then, does it assume its full significance.

To-morrow I will speak further on this subject.

If I were asked to map out a course of medical study to cover a certain period of time, I should begin—after the necessary scientific knowledge had been acquired—by distinguishing the various functions in the organism of man. I should feel bound to advise a study, both in the anatomical and physiological sense, of the transformation of the foodstuffs from the stage where they are worked upon by the ptyalin and pepsin to the point where they are taken up into the blood. Then, after considering the whole alimentary canal concerned with digestion in the narrower sense, I should pass on to the system of heart and lungs and all that is connected with it. This would be followed by a study of the kidneys and, later on, their relation to the system of nerves and senses—a relation not properly recognised by orthodox science to-day. Then I should lead on to the system of liver, gall and spleen, and this cycle of study would gradually open up a vista of the human organism, leading to the knowledge which it is the task of Spiritual Science to develop. Then, with the illumination which would have been shed upon the results of empirical research, one would be able to pass on to therapy.

In the few days at our disposal, it is of course possible for me to give only a few hints about this wide and all-embracing domain. A great deal, therefore, of what I have to say will be based upon an unusual conception of empirical facts, but I think it will be quite comprehensible to anyone who possesses the requisite physiological and therapeutic knowledge. I shall have to use somewhat unfamiliar terms, but there will really be nothing that cannot in some way be brought into harmony with the data of modern empirical knowledge—if these data are studied in all their connections. Everything I say will be aphoristic, merely hinting at ultimate conclusions. Our starting point, however, must be the objective and empirical investigations of modern times, and the intermediate stages will have to be mastered by the work of our doctors. This intermediate path is exceedingly long but it is absolutely essential, for the reason that, as things are to-day, nothing of what I shall bring before you will be whole-heartedly accepted if these intermediate steps are not taken—at all events in regard to certain outstanding phenomena. I do not believe that this will prove to be as difficult as it appears at present, if people will only condescend to bring the preliminary work that has already been done into line with the general conceptions I am trying to indicate here. This preliminary work is excellent in many respects, but its goal still lies ahead.

In the last lecture I tried to show you how a widening out of ordinary knowledge can give us insight into the being of man. And now, bearing in mind what I have just said, let me add the following. It may, to begin with, be a stumbling-block to hear it said in Anthroposophy that man, as he stands before us in the physical world, consists of a physical organisation, an etheric organisation, an astral organisation and an Ego-organisation. These expressions need not be an obstacle. They are used merely because some kind of terminology is necessary. By virtue of this Ego-organisation, the point where his inner experiences are focused and unified, man is able to unfold that inner cohesion of soul-life which is not present in the animal. The Ego is really the focus whence the whole organic activity of man proceeds, in waking consciousness at all events. A further expression of the Ego is the fact that during earthly life the relation of man to sexual development is not the same as that of the animal. Essentially—though of course exceptions are always possible—the constitution of the animal is such that sexual maturity represents a certain point of culmination. After this, deterioration sets in. This organic deterioration may not begin in a very radical sense after the first occurrence of sexual activity, but to a certain extent it is there. On the other hand, the physical development of the human being receives a certain stimulus at puberty. So that even in the outer empirical sense—if we take all the factors into account—there is already a difference here between the human being and the animal.

You may say that it is really an abstraction to speak of physical, etheric, astral and Ego organisations. The objection has in fact often been made, especially from the side of philosophy, that this is an abstract classification, that we take the functions of the organism, distinguish between them, and—since distinctions do not necessarily point back to any objective causes—people think that it is all an abstraction. Now that is not so. In the course of these lectures we shall see what really lies behind this classification and division, but I assure you they are not merely the outcome of a desire to divide things into categories.

When we speak of the physical organisation of man, this includes everything in the organism that can be dealt with by the same methods that we adopt when we are making experiments and investigations in the laboratory. All this is included when we think or speak of the physical organisation of man. In regard to the etheric organisation that is woven into the physical, however, our mode of thought can no longer confine itself to the ideas and laws obtaining when we are making experiments and observations in the laboratory. Whatever we may think of the etheric organisation of man as revealed by super-sensible knowledge, and without having to enter into mechanistic or vitalistic theory in any way, it is apparent to direct perception (and this is a question which would be the subject of lengthy study in my suggested curriculum) that the etheric organisation as a whole is involved—functionally—in everything of a fluid, watery nature in the human organism. The purely physical mode of thought, therefore, must confine itself to what is solid in the organism, to the solid structures and aggregations of matter. We understand the organism of man aright only when we conceive of its fluids as being permeated through and through with life, as living fluids—not merely as the fluids of outer Nature. This is the sense in which we say that man has an etheric body. It is not necessary to enter into hypotheses about the nature of life, but merely to understand what is implied by saying that the cell is permeated with life. Whatever views we may hold—mechanistic, idealistic, animistic or the like—when we say, as the crass empiricist also says, that the cell has life, this direct perception to which I am referring shows that the fluid nature of man is likewise permeated with life. But this is the same as saying: Man has an etheric body. We must think of everything solid as being embedded in the fluid nature. And here already we have a contrast, in that we apply the ideas and laws obtaining in the inorganic world to the solid parts of man's being, whereas we think not only of the cells—the smallest organisms present in man—as living, but of the fluid nature in its totality as permeated with life.

Further, when we come to the airy nature of man, it appears that the gases in his being are in a state of perpetual permutation. In the course of these lectures we shall have to show that this is neither an inorganic permutation nor merely a process of permutation negotiated by the solid organs, but that an individual complex of law controls the inner permutation of the gases in man. Just as there is an inner law in the solid substances, expressing itself, among other things, in the relationship between the kidneys and the heart, so we must postulate the existence of a law within the airy or gaseous organism—a law that is not confined to the physical, solid organs. Anthroposophy describes this complex of law, which underlies the gaseous organism, as astral law, as the astral organisation. These astral laws would not be there in man if his airy organisation had not permeated the solid and the fluid organisations. The astral organisation does not penetrate directly into the solids and the fluids. It does, however, directly penetrate the airy organisation. This airy organisation penetrates the solids and the fluids, but only because the presence of an organised astral nature gives it definite, though fluctuating, inner form. A study of the aggregate conditions thus brings us to the following conclusions: In the case of the solid substances in man we need assume nothing more than a physical organisation; in the case of the living fluidity which permeates the solid, physical organisation, we must assume the existence of something that is not exhausted in the forces of physical law, and here we come to the etheric organism—a system that is self-contained and complete in itself. In the same sense I give the name of astral organisation to that which does not directly penetrate into the solids and fluids but first of all into the airy organisation. I prefer to call this the astral organism because it again is a self-contained system.

And now we come to the Ego-organisation, which penetrates directly only into the differentiations of warmth in the human organism. We can therefore speak of a warmth organism, a warmth ‘being.’ The Ego-organisation penetrates directly into this warmth being. The Ego-organisation is a super-sensible principle and brings about the various differentiations of the warmth. In these differentiations of warmth the Ego-organisation has its immediate life. It also has an indirect life in so far as the warmth works upon the airy fluid and solid organisations.

In this way we gradually gain insight into the human organism. Now all that I have been describing expresses itself in physical man as he lives on the earth. The most intangible organisation of all—the Ego-warmth-organisation—works down indirectly upon the gaseous, fluid and solid organisations; and the same is true of the others. So that the way in which this whole configuration penetrates the constitution of man, as known to empirical observation, will find expression in any solid system of organs, verifiable by anatomy. Hence, taking the various organ-systems, we find that only the physical

—I mean the physically solid system—is directly related to its corresponding (physical) system of laws; the fluid is less directly related, the gaseous still less directly, and the element of warmth least directly of all, although even here there is still a certain relation.

Now all these things—and I can indicate them here only in the form of ultimate conclusions—can be confirmed by an extended empiricism merely from the phenomena themselves. As I say, on account of the short time at our disposal I can only give you certain ultimate conclusions.

In the anatomy and physiology of the human organism we can observe, to begin with, the course taken by the foodstuff. It reaches the intestines and the other intricate organs in that region, and is absorbed into the lymph and blood. We can follow the process of digestion or nourishment in the widest sense, up to that point. If we limit ourselves to this, we can get on quite well with the mode of observation (and it is not entirely mechanistic) that is adopted by natural science to-day. An entirely mechanistic mode of observation will not lead to the final goal in this domain, because the complex of laws observed externally in the laboratory, and characterised by natural science as inorganic law, is here functioning in the digestive tract: that is to say, already within the living organism. From the outset, the whole process is involved in life, even at the stage of the ptyalin-process.

If we merely pay heed to the fact that the complex of outer, inorganic law is involved in the life of the digestive tract, we can get on well quite, so far as this limited sphere is concerned, by confining ourselves merely to what can be observed within the physical organisation of man. But then we must realise that something of the digestive activity still remains, that the process of nourishment is still not quite complete when the intestinal tract has been passed, and that the subsequent processes must be studied from a different point of view. So far as the limited sphere is concerned, we can get on quite well if, to begin with, we study all the transformations of substance by means of analogies, just as we study things in the outer world. But then we find something that modern science cannot readily acknowledge but which is none the less a truth, following indeed from science itself. It will be the task of our doctors to investigate these matters scientifically and then to show from the empirical facts themselves that as a result of the action of the ptyalin and pepsin on the food-stuff, the latter is divested of every trace of its former condition in the outer world.

We take in foodstuff—you may demur at the expression ‘foodstuff’ but I think we understand each other—we take in foodstuff from the mineral, plant and animal kingdoms. It belongs originally to these three realms. The substance most nearly akin to the human realm is, of course, the mother's milk; the babe receives the milk immediately it has left the womb. The process enacted within the human organism during the process of nourishment is this: When the foodstuff is received into the realm of the various glandular secretions, every trace of its origin is eliminated. It is really true to say that the human organisation itself conduces to the purely scientific, inorganic mode of observation. In effect, the product of the assimilation of foodstuffs in man comes nearest of all to the outer physical processes in the moment when it is passing as chyle from the intestines into the lymph and blood-streams. The human being finally obliterates the external properties which the foodstuff, until this moment, still possessed. He wants to have it as like as possible to the inorganic state. He needs it thus, and this again distinguishes him from the animal kingdom.

The anatomy and physiology of the animal kingdom reveal that the animal does not eliminate the nature of the substances introduced to its body to the same extent, although we cannot say quite the same of the products of excretion. The substances that pass into the body of the animal retain a greater resemblance to their constitution in the outer world than is the case with man. They retain more of the vegetable and animal nature and proceed on into the blood-stream still in their external form and with their own inner laws. The human organisation has advanced so far that when the chyle passes through the intestinal wall, it has become practically inorganic. The purely physical nature comes to expression in the region where the chyle passes from the intestines into the sphere of the activity of heart and lungs.

It is really only at this point that our way of looking at things becomes heretical as regards orthodox science. The system connected with the heart and the lungs—the vascular system—is the means whereby the foodstuffs (which have now entered the inorganic realm) are led over into the realm of life. The human organisation could not exist if it did not provide its own life. In a wider sense, what happens here resembles the process occurring when the inorganic particles of albumen, let us say, are transformed into organic, living albumen, when dead albumen becomes living albumen. Here again we need not enter into the question of the inner being of man, but only into what is continually being said in physiology. On account of the shortness of time we cannot speak of the scientific theories as to how the plant produces living albumen, but in the human being it is the system of heart and lungs, with all that belongs to it, which is responsible for the transformation of the albumen into living substance after the chyle has become almost inorganic.

We can therefore say: The system of heart and lungs is there in order that the physical system may be drawn up into the etheric organisation. The system of heart and lungs brings about a vitalising process whereby inorganic substance is raised to the organic stage, is drawn into the sphere of life. (In the animal it is not quite the same, the process being less definite.) Now it would be absolutely impossible for this process to take place in the physical world if certain conditions were not fulfilled in the human organism. The raising and transformation of the chyle into an etheric organisation could not take place within the sphere of earthly law unless other factors were present. The process is possible in the physical world only because the whole etheric system pours down, as it were, into the physical, is membered into the physical. This comes to pass as a result of the absorption of oxygen in the breath. And so man is a being who can walk physically upon the Earth because his etheric nature is made physical by the absorption of oxygen. The etheric organisation is projected into the physical world as a physical system; in effect, that which otherwise could only be super-sensible expresses itself as a physical system, as the system of heart and lungs. And so we begin to realise that just as carbon is the basis of the organisms of animal, plant and man (only in the latter case in a less solid form) and ‘fixes’ the physical organisation as such, so is oxygen related to the etheric organisation when this expresses itself in the physical domain.

Here we have the two substances of which living albumen is essentially composed. But this mode of observation can be applied equally well to the albuminous cell, the cell itself. Only we widen out the kind of observation that is usually applied to the cell by substituting a macroscopic perception for the microscopic perception of the cell in the human being. We observe the processes which constitute the connection between the digestive tract and the system of heart and lungs. We observe them in an inner sense, seeing the relation between them, perceiving how an etheric organisation comes into play and is ‘fixed’ into the physical as the result of the absorption of oxygen.

But you see, if this were all, we should have a being in the physical world possessed merely of a digestive system and a system of heart and lungs. Such a being would not be possessed of an inner life of soul; the element of soul could have its life in only the super-sensible; and it is still our task to show how that which makes man a sentient being inserts itself into his solid and fluid constitution, permeating the solids and fluids and making him a sentient being, a being of soul. The etheric organisation in the physical world, remember, is bound up with the oxygen.

Now the organisation of soul cannot come into action unless there is a point d'appui, as it were, for the airy being, with a possibility of access to the physical organisation. Here we have something that lies very far indeed from modern habits of thought. I have told you that oxygen passes into the etheric organisation through the system of heart and lungs; the astral nature makes its way into the organisation of man through another system of organs. This astral nature, too, needs a physical system of organs. I am referring here to something that does not take its start from the physical organs but from the airy nature (not only the fluid nature) that is connected with these particular organs—that is to say from the airy organisation that is bound up with the solid substance. The astral-organic forces radiate out from this gaseous organisation into the human organism. Indeed, the corresponding physical organ itself is first formed by this very radiation, on its backward course. To begin with, the gaseous organisation radiates out, makes man into an organism permeated with soul, permeates all his organs with soul and then streams back again by an indirect path, so that a physical organ comes into being and plays its part in the physical organisation. This is the kidney system, which is regarded in the main as an organ of excretion. The excretory functions, however, are secondary. I will return to this later on, for I have yet to speak of the relation between the excretions and the higher function of the kidneys. As physical organs the kidneys are excretory organs (they too, of course, have entered the sphere of vitality), but besides this, in their underlying airy nature, they radiate the astral forces which now permeate the airy nature and from thence work directly into the fluids and the solids.

The kidney system, therefore, is that which from an organic basis imbues man with sentient faculties, with qualities of soul and the like—in short with an astral organism. Empirical science has a great deal to say about the functions of the kidneys, but if you will apply a certain instinctive inner perception to these functions, you will be able to discover the relations between inner sentient experience and the functions of the kidneys—remembering always that the excretions are only secondary indications of that from which they have been excreted. In so far as the functions of the kidneys underlie the sentient faculties, this is expressed even in the nature of the excretions.

If you want to extend scientific knowledge in this field, I recommend you to make investigations with a man of the more sensitive type and try to find out the essential change that takes place in the renal excretions when he is thinking in a cold or in a hot room. Even purely empirical tests like this, suitably varied in the usual scientific way, will show you what happens. If you make absolutely systematic investigations, you will discover what difference there is in the renal excretions when a man is thinking either in a cold or a warm room. You can also make the experiment by asking someone to think concentratedly and putting a warm cloth round his head. (The conditions for the experiment must of course be carefully prepared.) Then examine the renal excretions, and examine them again when he is thinking about the same thing and cold compresses have been put on his feet.

The reason why there is so little concern with such inquiries to-day is because people are averse from entering into these matters. In embryological research into cell-fission, science does not study the allantois and the amnion. True, the discarded organs have been investigated, but to understand the whole process of embryonic development the accessory organs must be studied much more exactly even than the processes which arise from the division of the germ-cell. Our task here, therefore, is to establish starting-points for true investigation. This is of the greatest significance, for only so shall we find the way, as we must do, towards seeing man, not as a visible but as an invisible “giant” cell.

To-day, science does not speak of the cell as it speaks of the human being, because microscopy does not lead so far. The curious thing is that if one studies the realm of the microscopic with the methods I am here describing, wonderful things come to light—as for instance the results achieved by the Hertwig school. The cell can be investigated up to a certain point in the microscope, but then there is no possibility of, further research into the more complicated life-processes. Ordinary empiricism comes to a standstill here, but with Spiritual Science we can follow the facts further. We now look at man in his totality, and the tiny point represented by the cell grows out, as it were, into the whole being of man.

From this we can proceed to learn how the purely physical organisation is connected with the structure of carbon, just as the transition to the etheric organisation is connected with the structure of oxygen. If, next, we make exact investigations into the kidney system, we find a similar connection with nitrogen. Thus we have carbon, oxygen, nitrogen; and in order to trace the part played by nitrogen in the astral permeation of the organism, you need only follow, through a series of accurate experiments, the metamorphoses of uric acid and urea. Careful study of the secondary excretions of uric acid and urea will give definite evidence that the astral permeation of man proceeds from the kidney system. This will also be shown by other things connected with the activity of the kidneys, even to the point where pathological conditions are present—when, let us say, we find blood corpuscles in the urine. In short, the kidney system radiates the astral organisation into the human organism. Here we must not think of the physical organisation, but of the airy organisation that is bound up with it. If nitrogen were not present, the whole process would remain in the domain of the super-sensible, just as man would be merely an etheric being if oxygen were not to play its part. The outcome of the nitrogen process is that man can live on earth as an earthly being. Nitrogen is the third element that comes into play.

There is thus a continual need to widen the methods adopted in anatomy and physiology by applying the principles of Spiritual Science. It is not in any sense a matter of fantasy. We ask you to study the kidney system, to make your investigations as accurately as you possibly can, to examine the urea and the excretions of uric acid under different astral conditions, and step by step you will find confirmation of what I have said. Only in this way will the mysteries of the human organism reveal themselves to you.

All that enters into man through the absorption of foodstuff is carried into the astral organism by the kidney system. There still remains the Ego-organisation. The products of digestion are received into the Ego-organisation primarily as a result of the working of liver and gall. The warmth and the warmth-organisation in the system of liver and gall radiate out in such a way that man is permeated with the Ego-organisation, and this is bound up with the differentiations of warmth in the organism as a whole.

Now it is quite possible to make absolutely exact investigations into this. Take certain lower animals where there is no trace at all of an Ego-organisation in the psychological sense, and you will find no developed liver, and still less any bile. These develop in the phylogeny of the animal kingdom only when the animal begins to show traces of an Ego-organisation. The development of liver and gall runs absolutely parallel with the degree to which the Ego-organisation unfolds in a living being. Here, too, you have an indication for a series of physiological investigations in connection with the human being, only of course they must cover the different periods of his life. You will gradually discover the relation of the Ego-organisation to the functions of the liver.

In certain diseases of children you will find, for instance, that a number of psychical phenomena, tending not towards the life of feeling but towards the Ego-activities, are connected with the secretion of gall. This might form the basis for an exceedingly fruitful series of investigations. The Ego-organisation is connected with hydrogen, just as the physical organisation is connected with carbon, the etheric organisation with oxygen and the astral organisation with nitrogen. It is, moreover, possible to relate all the differentiations of warmth—I can only hint at this—to the specific function carried out in the human organism by hydrogen in combination with other substances. And so, as we ascend from the material to the super-sensible and make the super-sensible a concrete experience by recognising its physical expressions, we come to the point of being able to conceive the whole being of man as a highly complicated cell, a cell that is permeated with soul and Spirit.

It is really only a matter of taking the trouble to examine and develop the marvelous results achieved by natural science and not simply leaving them where they are. My understanding and practical experience of life convince me that if you will set yourselves to an exhaustive study of the results of the most orthodox empirical science, if you will relate the most obvious with the most remote, and really study the connections between them, you will constantly be led to what I am telling you here. I am also convinced that the so-called ‘occultists’ whom you may consult—especially ‘occultists’ of the modern type—will not help you in the least. What will be of far more help is a genuine examination of the empirical data offered by orthodox science. Science itself leads you to recognise truths which can be actually perceived only in the super-sensible world, but which indicate, nevertheless, that the empirical data must be followed up in this or that direction. You can certainly discover the methods on your own account; they will be imposed by the facts before you. There is no need to complain that such guiding principles create prejudice or that they influence by suggestion. The conclusions arise out of the things themselves, but the facts and conditions prove to be highly complicated, and if further progress is to be made, all that has been learned in this way about the human being must now be investigated in connection with the outer world.

I want you now to follow me in a brief line of thought. I give it merely by way of example, but it will show you the path that must be followed. Take the annual plant which grows out of the earth in spring and passes through its yearly cycle. And now relate the phenomena which you observe in the annual plant with other things—above all with the custom of peasants who, when they want to keep their potatoes through the winter, dig pits of a certain depth and put the potatoes into them so that they may keep for the following year. If the potatoes were kept in an ordinary open cellar, they would not be fit to eat. Investigations have proved that the forces originating from the interplay between the sunshine and the earth are contained within the earth during the subsequent winter months. The dynamic forces of warmth and the forces of the light are at work under the surface of the earth during the winter, so that in winter the after-effects of summer are contained within the earth. The summer itself is around us, above the surface of the Earth. In winter, the after-effects of summer work under the earth's surface. And the consequence is that the plant, growing out of the earth in its yearly cycle, is impelled to grow, first and foremost, by the forces that have been poured into the earth by the sun of the previous year. The plant derives its dynamic force from the soil. This dynamic force that is drawn out of the soil can be traced up into the ovary and on into the developing seed. So you see, we arrive at a botany which really corresponds to the whole physiological process, only if we do not confine ourselves to a study of the dynamic forces of warmth and light during the year when the plant grows. We must take our start from the root, and so from the dynamic forces of light and warmth of at least the year before. These forces can be traced right up into the ovary, so that in the ovary we have something that really is brought into being by the forces of the previous year.

Now examine the leaves of a plant, and, still more, the petals. You will find that in the leaves there is a compromise between the dynamic forces of the previous year and those of the present year. The leaves contain the elements that are thrust out from the earth and those which work in from the environment. It is in the petals that the forces of the present year are represented in their purest form. The colouring and so forth of the petals represents nothing that is old—it all comes from the present year.

You cannot follow the processes in an annual plant if you take only the immediate conditions into consideration. Examine the structural formations which follow one another in two consecutive years—all that the sun imparts to the earth, however, has a much longer life. Make a series of experiments into the way in which the plants continue to be relished by creatures such as the grub of the cockchafer, and you will realise that what you first thought to be an element belonging to the present year must be related to the sun-forces of the previous year.—You know what a prolonged larval stage the cockchafer passes through, devouring the plant with relish all the time.

These matters must be the subject of exact research; only the guiding principles can be given from the spiritual world. Research will show that the nature of the substances in the petals and leaves, for instance, is essentially different from that of the substances in the root or even the seed. There is a great difference between a decoct ion prepared from the petals or leaves of plants and an extract of substances found in roots or seeds. The effect of a decoction prepared from petals or leaves upon the digestive system is quite different from that of an extract prepared from roots or seeds. In this way you relate the organisation of man to the surrounding world, and all that you discover can be verified in a purely material sense. You will find, for instance, that disturbances in the process of the transition of the chyle into the etheric organisation, which is brought about by the system of heart and lungs, will be influenced by a preparation decocted from the petals of plants. An extract of roots or seeds influences the wider activity that works on into the vascular system and even into the nervous system. Along these lines we shall discover the rational connection between what is going on within the human organism and the substances from which our store of remedies may be derived.

In the next lecture I shall have to continue this subject, showing that there is an inner connection between the different structures of the plants and the systems of nerves and senses and digestion in man.

As we begin more and more to view the human organism in the way which I have unfortunately been able to indicate only very briefly, many things not otherwise appreciated in their full significance assume great importance. Very little heed is paid nowadays to what I have called in the appendix to my book, Riddles of the Soul, the threefold organisation of the physical being of man. Yet a right understanding of this threefold organisation is of the greatest significance for pathology and therapy. According to this threefold organisation of physical man, the system of nerves and senses is to be conceived of as being localised mainly in the head, only of course in this sense the head-organisation really extends over the whole being. The nervous and sensory functions of the skin, and also those within the organism, must be included. We cannot, however, arrive at a well-founded conception of the modes of activity in the organism unless—theoretically in the first place—we differentiate the system of nerves and senses from the rest of the organism as a whole.

The second, or rhythmic, system includes, in the functional sense, all that is subject to rhythm—primarily, therefore, the breathing system and its connection with the blood circulation. In the wider sense, too, there is the rhythm that is essentially present in the life of man, although he can break through it in many ways—I mean the rhythm of day and night, of sleeping and waking. Then there are other rhythms, the rhythmic assimilation of foodstuffs and the like. These latter rhythms are constantly broken by man, but the consequences have to be brought into equilibrium by certain regulative factors which are present in the organism. As a second member of the human organisation, then, we have the rhythmic system; and, as a third member, the metabolic organism, in which I include the limb-formations because the functional processes that arise as a result of the movements of the limbs are inwardly connected with the metabolism in general.

When we consider this threefold nature of man, we find that the organisation described in the last lecture as being mainly connected with the Ego has a definite relation to the metabolism in so far as the metabolic system extends over the whole being. Again, the rhythmic system has a definite connection with the system of heart and lungs. The functions of the kidneys, the forces that go out from the kidney system, are related to the astral organisation of the human being. In short, in his threefold physical nature man is related to the different members of his super-sensible being and also to the several organic systems—as I showed yesterday. But these relationships must be studied in more precise detail if they are to prove of practical value for an understanding of man in health and disease. And here we shall do best to start from a consideration of the rhythmic being of man.

This rhythmic organisation is very frequently misunderstood in respect of a very definite characteristic, namely the relation that is set up between the rhythm of the blood circulation and the rhythm of the breath. In the grown-up person, this relationship is approximately in the ratio of four to one. This, of course, is only the average, approximate ratio, and its variations in individuals are an expression of the measure of health and disease in the organism. Now, that which reveals itself in the rhythmic man as a ratio of four to one, continues in the organism as a whole. We have again a ratio of four to one in the relationship of the processes of the metabolic system (including the limbs) to the system of nerves and senses. This again can be verified by empirical data as in the case of other things mentioned in these lectures. Indeed, so far-reaching is this relationship that we may say: All the processes connected with metabolism in man take their course four times more quickly than the work done by the nervous and sensory activities for the growth of the human being.

The second teeth which appear in the child are an expression of what is proceeding in the metabolic system as a result of its coming continually into contact with the system of nerves and senses. All that flows from the metabolic system towards the middle, rhythmic system, set against that which flows from the nerves and senses system into the rhythmic system, is in the ratio of four to one. To speak precisely, we may take the breathing system to be the rhythmic continuation of the system of nerves and senses, and the circulatory system to be the rhythmic continuation of the metabolic system. The metabolic system sends its workings, as it were, up into the rhythmic man. In other words, the third member works into the second, and this expresses itself through the rhythm of blood circulation in daily life. The system of nerves and senses, again, sends its workings into the breathing system and this is expressed through the rhythm of the breath. In the rhythmic being of man we can perceive the ratio of four to one—for there are some seventy pulse-beats or so to eighteen breaths. In the relationships of the rhythms, the rhythmic being of man represents the contact between the system of nerves and senses and the metabolic system; and this can again be observed in any given life-period of man by studying the relation of all that proceeds from the metabolism in the general organic processes to all that goes out from the head system—the system of nerves and senses. This is a relationship of great significance.

In the child's second teeth there is an upward thrust of the metabolic system into the head, but the point about this meeting between the metabolic system and the system of nerves and senses is that the latter, to begin with, gets the upper hand. The following will make this clear to you. The second dentition at about the age of seven represents a contact between the metabolic system and the system of nerves and senses, but the nervous and sensory action dominates. The outcome of this contact of forces—which proceed from the nerves and senses on the one hand and the metabolic system on the other—is the development of the second teeth.

Again, in the period when the human being reaches puberty, a new contact occurs between the metabolic system and the system of nerves and senses, but this time the metabolic system dominates. This is expressed in the male sex by the change in the voice itself, which up to this period of life has been, essentially, a form of expression of the system of nerves and senses. The metabolic system pulses upwards and makes the voice deeper.

We can understand these workings by observing the extent to which they embrace the radiations in the human organism which originate in the kidney system and the liver-gall system on the one hand, and in the head and skin organisations on the other. This is an exceedingly interesting connection, and one which leads us into the deepest depths of the organisation of man. We can envisage the building and moulding of the organism thus: Radiations go out from the system of kidneys and liver, and they are met by the plastic, formative forces proceeding from the head. The forces from the system of kidneys and liver (naturally they do not only stream upwards but to all sides) have the tendency to work in a semi-radial direction, but they are everywhere thwarted by the plastic, formative forces which proceed from the head. We can thus understand the form of the lungs by thinking of it as being organised by the forces of the liver and kidneys, which are then met by the rounding-off forces proceeding from the head. The whole structure of man comes into being in this way: radiation from the systems of kidneys and liver, and then the rounding off of what has been radiated out by the forces proceeding from the head.

In this way we arrive at a fact of the greatest importance and one which can be confirmed empirically in every detail. In the process of man's development, in his growth, two sets of forces are at work: (1) forces that proceed from the systems of liver and kidneys, and (2) forces that proceed from the system of nerves and senses, which round off the forms and give them their surfaces. Both components play into each other, but not with the same rhythm. All that takes its start from the systems of liver and gall has the rhythm of metabolic man. All that proceeds from the head system has the rhythm of the man of nerves and senses. So that when the organism is ready for the coming of the second teeth, at about the seventh year of life, the metabolic system, with all that proceeds from the liver and kidneys (which is met by the rhythm of the heart), is subject to a rhythm that is related to the other rhythm, proceeding from the head, in the ratio of four to one. Thus not until the twenty-eighth year of life is the head organisation of man developed to the point reached by the metabolic organisation at the age of seven. The plastic principle in man, therefore, develops more slowly than the radiating, principle—in effect, four times as slowly. Connected with this is the fact that at the end of the seventh year of life, in respect of what proceeds from the metabolic activities, we have developed to the point reached by growth in general (in so far as this is subject to the system of nerves and senses) only at the twenty-eighth year.

Man is thus a complicated being. Two streams of movement subject to a different rhythm are at work in him. And so we can say: The coming of the second teeth is due in the first place to the fact that everything connected with the metabolism comes into contact with the slower, but more intense plastic principle, and in the teeth the plastic element dominates. At the time of puberty, the metabolic element preponderates the plastic influences withdraw more into the background, and the whole process is expressed in the male sex by the familiar phenomenon of the deepened voice.

Many other things in the being of man are connected with this: for instance the fact that the greatest possibility of illness occurs, fundamentally speaking, during the period of life before the coming of the second teeth—the first seven years of life. When the second teeth appear, the inner tendency of the human being to disease ceases to a very great extent. The system of education which it was our task to build up compelled me to make a detailed study of this matter, for it is impossible to found a rational system of education without these principles which concern the human being in health and disease. In his inner being, man is in the healthiest state during the second period of life, from the change of teeth to puberty. After puberty, an epoch begins again when it is easy for him to fall a prey to illness. Now the tendency to illness in the first period of life is of quite a different nature from the tendency to illness after puberty. These two possibilities of illness are as different, shall I say, as the phenomena of the second dentition and the change in the male voice.

During the first period of life, up to the change of teeth, everything goes out from the child's organisation of nerves and senses to the outermost periphery of the organism. The system of nerves and senses still has the upper hand at the change of teeth. You will be able to form a general conception of pathological phenomena during the first seven years of life if you say to yourselves: It is quite evident here that the radiations from the system of liver and kidneys are rounded off, stultified in a sense, by the plastic principle working from the system of nerves and senses. This plastic element is the main field of action of everything which I have described in these lectures as being connected with the Ego-organisation and astral organisation of man.

Now it may seem strange that I previously spoke of the Ego-organisation as going out from the system of liver and gall and the astral organisation from the kidney system, and that I now say: everything connected with the Ego and astral organisations emanates from the head. But we shall never understand the human organism with all its complexities if we say baldly that the Ego-organisation proceeds from the system of liver and gall and the astral organisation from the system of kidneys. We must realise that in the first life-period, up to the change of teeth, these radiations from the system of liver and kidneys are worn down by the action of nerves and senses. This rounding-off process is the essential thing. Strange to say, the forces supplied to the Ego and astral organisations by the systems of liver, gall and kidneys reveal themselves as a counter-radiation, not in their direct course from below upwards, but from above downwards. Thus we have to conceive of the child's organisation as follows: The astral nature radiates from the kidney system, and the Ego-organisation from the liver system, but these radiations have no direct significance. Both the liver system and the kidney system are, as it were, reflected back from the head system and the reflection in the organism is alone the active principle.

How, then, are we to think of the astral organisation of the child? We must think of the workings of the kidneys as being radiated back from the head system. What of the Ego-organisation in the child? The workings of the system of liver and gall also are radiated back from the head system. The physical system proper and the etheric system work from below upwards, the physical organisation having its point of departure in the digestive system and the etheric organisation in the system of heart and lungs. These organisations work from below upwards and the others from above downwards during the first epoch of life. And in the radiation from below upwards works the rhythm which is related as four to one to the radiation working from above downwards.

It is a pity that the indications here have to be so brief, but they really are the key to the processes of childhood. If you want to study the most typical diseases of children, you may divide them into two classes. On the one side you will find that the forces streaming from below upwards meet the forces streaming from above downwards with a rhythm of four to one, but that there is no co-ordination. If it is the upward-streaming forces with their rhythm of four that refuse to incorporate themselves into the individuality, while the inherited rhythm of the head system (representing the one) is in order, then we find all those organic diseases of childhood which are diseases of the metabolism, arising from a kind of congestion between the system of nerves and senses and the metabolic system. I mean that the metabolism is not quite able to adapt itself to that which radiates out from the system of nerves and senses. Then we get, for example, that strange disease in children which leads to the formation of a kind of purulent blood. All other children's diseases which may be described as diseases of the metabolism arise in this way.

On the other hand, suppose the metabolic organism is able to adapt itself to the individuality of the child, and the hygienic conditions are such that the child lives healthily in its environment—if, for example, we give the proper kind of food. But if, as a result of some inherited tendency, the system of nerves and senses working from above downwards does not rightly harmonise with the radiations from liver, gall and kidneys, diseases accompanied by fits or cramp-like conditions arise, the cause of them being that the Ego and astral organisations are not coming down properly into the physical and etheric organisation.

Diseases of children, therefore, arise from two opposite sides. But it is always true that we can understand these diseases of the child's organism only by directing our attention to the head and the system of nerves and senses. The metabolic processes in the child must not only be brought into harmony with outer conditions but also with the system of nerves and senses. In the first period of life, up to the change of teeth, a practical and fundamental knowledge of the system of nerves and senses is necessary, and we must observe that while in the child everything radiates from the head organisation, it is none the less possible for the metabolism to press too far forward, if it so be that the metabolism is normal, while the head organisation through hereditary circumstances is too feeble.

Now when the second life-period, from the change of teeth to puberty, sets in, it is the rhythmic organism which is the centre of activity. The astral and etheric organisations are essentially active here. Into the astral and etheric organisations between the change of teeth and puberty, streams everything that arises from the functions of the breathing and circulatory systems. The reason why the organism itself can afford the human being the greatest possibility of health during this period of life is that these systems of breathing and circulation can be regulated from outside. The health of school-children of this age is very dependent on hygienic and sanitary conditions, whereas during the first period of life external conditions cannot affect it to the same extent.

The tremendous responsibility resting upon us in regard to the medical aspect of education is that a true knowledge of man tells us that we may have dealt wrongly with the tendencies to disease which make their appearance between the seventh and fourteenth years of life. During this period the human being is not really dependent on himself; he is adjusting himself to his environment by breathing in the air and by means of all that arises in his blood circulation as a result of the metabolic processes. Metabolism is bound up with the limb-organisation. If children are given the wrong kind of drilling or are allowed to move wrongly, outer causes of disease are set up. Education during the Elementary School age should be based upon these principles. They should be taken into strictest account through all the teaching.

This is never done in our days. Experimental psychology—as it is called—has a certain significance which I well appreciate, but among other errors it makes the mistake of speaking like this: Such and such a lesson causes certain symptoms of fatigue in the child; such and such a lesson gives rise to different symptoms of fatigue, and so forth. And according to the conditions of fatigue thus ascertained, conclusions are drawn as to the right kind of curriculum. Yes—but, you see, the question is wrongly put. From the seventh to the fourteenth years, all that really concerns us is the rhythmic system, which does not tire. If it were to tire, the heart, for instance, could not continue to act during sleep through the whole of earthly life. Neither does the action of breathing cause fatigue. So when it is said: heed must be paid to the degree of fatigue arising from an experiment—the conclusion should be that if there is fatigue at all, something is amiss. Between the seventh and fourteenth years our ideal must be to work upon the rhythmic system of the child and not, primarily, upon the head system. In effect, education must be imbued with the quality of art. Then we shall be working upon the rhythmic system, and it will be quite possible to correct all the conditions of fatigue arising from false methods of teaching. Excessive strain on the memory, for example, will always affect the breathing action, even though it be in a mild way, and the results will appear only in later life.

At puberty and afterwards, the opposite holds good. Causes of disease may then again arise in the organism itself, in the metabolic-limb-system. This is because the food substances assert their own inherent laws, and then we are faced with an excessively strong working of the physical and etheric organisms.

In the organism of the very young child, therefore, we are essentially concerned with the Ego-organisation and the astral organisation working by way of the system of nerves and senses; in the period between the change of teeth and puberty we are concerned mainly with the activity of the astral and etheric organisations arising from the rhythmic system; after puberty we have to do with the predominance of the physical and etheric organisations arising from the metabolic system. Pathology confirms this, and I need only call your attention to certain typical diseases of women; metabolic diseases proper arise from out of the inner being after puberty—metabolism has the upper hand. The products of metabolism get the better of the system of nerves and senses instead of duly harmonising with its activities. In diseases of children before the change of teeth there is a wrongful predominance on the part of the system of nerves and senses. The healthy period lies between the change of teeth and puberty; and after puberty the metabolic organism, with its quicker rhythm, begins to dominate. This quicker rhythm then expresses itself in all that is connected with metabolic deposits which form because the plastic forces from the head do not make a right contact with them. The result of this is that the metabolism invariably gets the upper hand.

I am very sorry that I can speak of these things only in a cursory, aphoristic way, but my aim is to indicate at least the final conclusion, which is that the functional activities in the human being are the primary factors, and that formations and deformations must be regarded as proceeding from these functional activities. In the outer sense this means that up to the seventh year of the child's life the plastic, rounding-off forces work with particular strength. The plastic structure of the organs is brought to such a point by the forces arising from the system of nerves and senses that the plastic moulding of the teeth, for example, up to the time of the second dentition, is an activity that never occurs again. As against this, the permeation of the organism with forces coming from the metabolism enters upon an entirely new phase when—as happens at puberty—some of the metabolic activities are given over to the sex organs. This leads to an essential change in the metabolic processes.

It is all-important to make a methodical and detailed study of the matters I have indicated to you. The results thus obtained can then be co-ordinated in the truly scientific sense if they are brought into line with what I told you at the end of the last lecture, and related to the working of the Cosmos outside man.

How then can we approach therapeutically all that radiates out so complicatedly from the kidney system, from the liver system? We have simply to call forth changes by working on it from outside. We can approach it if we hold fast to what is observable in the plant—I mean, the contrast between the principle of growth which is derived rather from the preceding year or years, and, on the other hand, those principles of growth which come from the immediate present. Let us return once more to the plant. In the root and up to the ovary and seed-forming process we have that which is old in the plant, belonging essentially to the previous year. In all that develops around the corona we have that which belongs to the present. And in the formation of the green leaves there is a working together of the present and the past. Past and present, as two component factors, have united to produce the leaves.

Now everything in Nature is interrelated, just as everything is interrelated in the human organism, in the intricate way I have described. The point is to understand the relationships. Everything in Nature is interrelated, and by a simpler classification of what is revealed in the plant we come to the following.

In the terminology of an older, more instinctive conception of medicine we find constant mention of the sulphurous or the phosphoric. These sulphurous or phosphoric elements exist in those parts of the plant which represent in the blossom—not in the ovary and stigma—the forces of the present year. When, therefore, you make a decoction from these particular organs of the plant (thereby extracting also what is minerally active in them) you obtain the phosphoric or sulphurous principle. It is quite incorrect to imagine that the doctors of olden times thought of phosphorus and sulphur in the sense of modern chemistry. They conceived of them in the way I have indicated. According to older medicine, a decoction prepared from the petals of the red poppy, for instance, would have been “phosphoric” or “sulphurous.”

On the other hand, in a preparation derived from a treatment of the leaves of a plant, we get the mercurial principle, as it was called in ancient terminology. This, of course, means the mercurial nature, not the substance of quicksilver in our sense. (To use pine-needles, for example, is quite a different thing from using, say, the leaves of cabbages).

Everything connected with root, stem or seed was called the salt-like in older medical terminology. I am saying these things only for the sake of clarity, for with our modern scientific knowledge we cannot go back to older conceptions. A series of investigations should be made to show, let us say, the effects of an extract prepared from the roots of some plant on the head organisation, and hence on certain diseases common to childhood.

A highly significant principle will come to light if we investigate the effects of substances drawn from the roots and seeds of plants on the organisation of the child before the change of teeth. Again, for illnesses of the kind that come from outside—and, fundamentally speaking, all illnesses between the change of teeth and puberty are of this kind—we obtain remedies, or at least preparations which have an effect upon such illnesses, from leaves and everything akin to the nature of leaves in the plant. I am speaking in the old sense here of the mercurial principle, which we meet in a stronger form in quicksilver itself. The fact that mercury is a specific remedy for certain sexual diseases, externally acquired, is connected with this. Sexual diseases are really nothing but the intensification of illnesses that may arise in an extremely mild form in the second period of life, from the seventh to the fourteenth years. They do not then develop into sexual diseases proper because the human being is not yet sexually mature. If it were otherwise, a great many diseases would attack the sexual organs. Those who can really perceive this transition from the eleventh, twelfth and thirteenth years, on into the fourteenth, fifteenth and sixteenth years, will realise that at this age symptoms that arise in earlier life in quite another form express themselves as abnormalities of the sexual life.

Further, there are diseases which have their origin in the metabolism. In so far as the metabolism is bound up with the physical and etheric systems of man, we find diseases which must be considered in connection with the workings of the petal nature of plants.

The cursory way of dealing with these matters which is necessary here may make a great deal appear fantastic. Everything can, nevertheless, be verified in detail. The obstacles that make it so difficult to approach orthodox medicine are really due to the fact that, to begin with, it all seems beyond the range of verification. We have to reckon with such intricate phenomena in the human organism as the particularly striking example of which I spoke at the beginning of this lecture, describing it in such a way that it was apparently irreconcilable with what I said yesterday. It clears up, however, when we realise that what goes out from the system of liver and kidneys emerges first in the reactions it calls forth, and in this sense it represents something quite essential for the Ego-organisation and astral organisation of man. In this case it is especially evident. But there is a similar principle of immediate co-operation and counter-action between the rhythms of the blood and of the breathing. Here, too, many an influence that proceeds from the rhythm of the blood must first be looked for in the counter-beat of the breathing rhythm, and vice versa.

And now connect this with the fact that the Ego-organisation really lives in the inner warmth of man, and that this warmth permeates the airy, gaseous being. In the forces proceeding from the Ego and astral organisms, we have, from a physical point of view, something that is working primarily from the warmth organisation and the airy, gaseous organisation. This is what we have to observe in the organism of the very young child. We must seek the cause of children's diseases by studying the warmth and airy organisations in the human being. The effects that appear when we work upon the warmth and airy organisations with preparations derived from roots or seeds, are caused by the fact that two polaric forces come into contact, the one stimulating the other. Substances taken from seeds or roots and introduced into the organism stimulate all that goes out from the warmth organisation and the airy organisation of the human being.

Now in the influences working, so to speak, from above downwards, we can discern in the human being, from the very outset, a warmth and air vibration which is strongest of all in childhood, although in reality it is not a vibration but a time-structure of a living kind—an organic structure in the flow of time. And on the other hand we have that in the physical-etheric organism which goes from below upwards—that is to say, the solid and fluid organisation of man. Moreover these two are in mutual interaction, inasmuch as the fluid and gaseous organisations permeate one another in the middle, bringing forth an intermediate phase by their mutual penetration, just as there exists in the human organism the well-known intermediate stage between the solid and the fluid. So likewise in the living and sentient organism we must look for an intermediate phase between the fluid and the gaseous, and again a phase between the gaseous and the element of warmth.

Please note that everything I am saying here in a physiological sense is of importance for pathology and therapy. When we observe this intricate organism of man we find, of course, that one system of organs is perpetually pouring out its influences into another system of organs. If we now observe the whole organic action expressed in one of the sense-organs, in the ear, for example, we find the following: Ego-organisation astral organisation, etheric and physical organisations are all working together in a definite way. The metabolism permeates the nerves and senses; rhythm is brought into this by the processes of breathing in so far as they work into the ear, and by the blood circulation. All that I have thus tried to make plain to you in diverse ways, threefold and fourfold (in the three members of the human being and in the fourfold organisations which I explained)—all this finds expression in definite relationships in every single organ. And in the long run, all things in man are in constant metamorphosis.

For instance—that which occurs normally in the region of the ear, why do we call it normal? Because it appears precisely as it does in order that the human being as a whole, even as he lives and moves on earth, may come into existence. We have no other reason to call it normal. But consider now the special circumstances, the special formative forces that work here in the ear by virtue of the ear's position, notably by virtue of the fact that the ear is at the periphery of the organism. Suppose that these circumstances are working in such a way that a similar relationship arises by metamorphosis at some other place in the interior of the body. Instead of the relationship which is proper to that place in the body, there arises a relationship among the various members similar to what is normal in the region of the ear. Then there will grow at this place in the body something that really tends to become an ear—forgive this very sketchy way of hinting at the facts. I cannot express what I want to say in any other way, as I am obliged to say it in the briefest outline. For instance, this something may grow in the region of the pylorus, in place of what should arise there. In a pathological metamorphosis of this kind we have to see the origin of tumours and similar formations. All tumour formations, up to carcinoma, are really misplaced attempts at the formation of sense-organs.

If, then, you bear in mind that the origin of a morbid growth is a misplaced attempt at the formation of a sense-organ, you will find what part is played in the child's constitution—even in embryonic existence—by the organisms of warmth and air in order that these sense-organs may come into being. These organs can indeed be brought into being only through the organisms of warmth and air by virtue of the resistance of the solid and fluid organisms, which results in a formation composed of both factors. This means that we must observe the relationship existing between the physical organism (in so far as this expresses itself in the metabolism, for example) and the formative, plastic organism (in so far as this expresses itself in the system of nerves and senses). We must, so to speak, perceive how the metabolic system radiates out the forces which bear the substance along with them, and how the substance is plastically moulded in the organs by the forces brought to meet it by the system of nerves and senses.

Bearing this in mind, we shall learn to understand what a tumour-formation really is. On the one side there is a false relationship between the physical-etheric organism in so far as it expresses itself in the radiating metabolic processes on the one side, and between the Ego-organisation and astral organism on the other (in so far as the Ego and astral organisations express themselves in the warmth and airy organisations respectively). Ultimately, therefore, we have above all to deal with the relation between the metabolism and the warmth organisation in man, and in the case of an internal tumour—although it is also possible with an external tumour—the best treatment is to envelop it in warmth. (I shall speak of these things tomorrow when we come to consider therapy). The point is to succeed in enveloping the tumour with warmth. This brings about a radical change in the whole organisation. If we succeed in surrounding the tumour with warmth, then—speaking crudely—we shall also succeed in dissolving it. This can actually be achieved by the proper use of certain remedies which are injected into the organism. We may be sure that in every case a preparation of viscum, applied in the way we advise around the abnormal organ—for instance around the carcinomatous growth—will generate a mantle of warmth, only we must first have ascertained its specific effect upon this or that system of organs. We cannot, of course, apply exactly the same preparation to carcinoma of the breast as to carcinoma of the uterus or of the pylorus. Further, we can be sure that no result will be achieved if we do not succeed in producing the right reaction—namely, a state of feverishness. The injection must be followed by a certain rise in the patient's temperature. You can at once expect failure if no condition of feverishness is produced.

I wanted to tell you this as a principle in order to make you understand that these things depend upon a ratio; but the ratio is merely a regulating principle. You will find that the statements based on this principle can be verified, as all such facts are verified by the methods of modern medicine. There is no question of asking you to accept these things before they have been tested, but it is really true that anyone who enters into them can make remarkable discoveries.

Although this brief exposition may be first be somewhat confusing, everything will clear up if you will go into the subject deeply.

To-morrow I propose to speak of certain matters in the realm of therapy, and then a great deal which seems to have been left rather in the air will be further explained.

In these lectures, of course, it can be a question only of describing certain ways of approach and therapeutic methods, as revealed by Spiritual Science. The short time at our disposal makes it impossible to enter into details. My own opinion, however, is that at the beginning of the work which it is the aim of Spiritual Science to carry through in the domain of medicine, the most important thing is for our point of view and our method of approach to be made quite clear. In certain specific details this point of view has been carefully followed in the preparation of our remedies. How we can proceed to form more general conceptions in special cases of illness will perhaps not be so immediately evident, but in describing certain principles of method to-day I will do my best to indicate matters which will help in this direction also.

The human organism in health and in disease—or rather in its state of health and in its approach towards health—is really unintelligible unless the so-called normal functions are regarded as being, fundamentally, metamorphoses of those functions which must be called into action in order to combat pathological conditions. And here we must always take account of the fact that the human organism is inwardly filled with processes which are not the same as those in the outer world. To begin with, let us remind ourselves that everything man takes into himself from the plant world, for instance, must be worked upon by the digestive system before it can be carried to a higher stage of life. The process of vitalization must be an activity of the human being himself; indeed, the human organism could not exist without it. Now it must be clear to us from the outset that the plant-covering of our earth is passing through the opposite process from that which takes its course within the organism of man. When we speak of a process of vitalisation along the path traversed by the foodstuffs in the organism—that is to say of a curve ascending, as it were, from the essentially inorganic to the state of vitalisation, from there to a condition which can be the bearer of feeling and finally to a condition which can be the bearer of the Ego-organisation—when we speak of the transformation of the foodstuff up to the point where it is received into the astral organism (the bearer of feeling), we are describing a process of increasing vitalisation of what is taken in through the food.

The reverse occurs in the plant. In all the peripheral organs of the plant, that is to say in the development of the plant from below upwards, in the production of the leaves and blossoms, we have, fundamentally speaking, a process of devitalisation. The vitality per se is preserved for the seed only. If we are speaking of the actual plant itself—for the seed in the ovary really represents the next plant that will come into being, that which is stored up for the future plant—if, as I say, we are speaking of the plant, it is not a process of vitalisation that is taking place from below upwards. The vitality is drawn from what is stored up by the earth out of the warmth and sunlight of the previous summer. The strongest life-force inheres in the root-nature, and there is a gradual process of devitalisation from below upwards.

In flower-petals which contain strong ethereal oils, we have an expression of the most powerful devitalising process of all. Such a process is, for instance, often connected with the actual production of sulphur. The sulphur is then contained, as substance, in the ethereal oil of the petals—or is at any rate closely akin to it and is responsible for the process whereby the plant is led over into the realm of the most delicate inorganic substance—which is still, however, on the borderline of the organic. It is essential to realise what it is that we are bringing into the human organism when we introduce plant-substances. The plant is engaged in the opposite process from that which occurs in the organism of man.

If we start from this and turn to consider illness and disease, we shall say to ourselves: Plant-substance—it is the same with other substances in outer Nature, and to a much higher degree with animal-substance—plant-substance is really opposed to that which unfolds in the human organism as a tendency to generate this or that process. So that when, without any kind of preconception, we study the process of nourishment in man, we must admit that all foodstuff introduced into the organism is something which this organism has utterly to transform. Fundamentally speaking, all nourishment is the beginning of a certain poisoning. Actual poisoning is only a radical metamorphosis of what arises in a mild form when any foodstuff is brought into touch, let us say, with the ptyalin. The further course of the digestive process, namely what is brought about by the activity of the kidneys which I described to you, is always a process of eliminating the poisoning. So that we pass through the rhythm of a mild poisoning and its elimination simply when we eat and digest our daily food. This represents the most delicate metamorphosis of the process which arises in greater intensity when a remedy is introduced into the organism. That is why in the nature of things it is nonsense to be fanatical about medicine that is ‘free from poison.’ It is nonsense because the only point at issue is this: In what way are we intensifying what already happens in ordinary digestion by introducing something into the organism that will give rise to a process more foreign to this organism than ordinary digestion?

A very profound understanding of the human organism is necessary before we can estimate the value for it of an external remedy. Let us begin with something that is always present as a remedial agent in the human organism—the iron in the blood. The iron in the blood unceasingly plays the role of a remedial agent, protecting man from his innate tendency to disease. I will describe it to you, to begin with, in a primitive way. You know that if the brain, with its weight of some 1,500 grammes, were to rest upon its base, the cerebral blood-vessels there would obviously be crushed. The brain does not rest upon its base but swims in the cerebral fluid, and in accordance with the principle of buoyancy, loses as much of its weight as the weight of the volume of fluid displaced. Thus the brain presses on its base with a weight of only about 20 grammes, instead of 1,500 grammes. This is a fact of fundamental importance because it shows us that the force of gravity is not the determining factor in that which underlies the functions of the brain, in Ego-activity, for instance. This Ego-activity and also, to a great extent, conceptual activity—in so far as it is not volitional but purely conceptual, ideative activity—is not dependent on the gravity of the substance in question but on the force of buoyancy. (I am speaking here entirely of the physical correlate, namely, the brain activity.) It is dependent on the force which strives to alienate the substance from the earth. In our Ego and our thoughts we do not live in the element of weight, but in the force of buoyancy.

The same thing holds good for much else in the human organism—above all, the iron-bearing corpuscles swimming in the blood. Each of these corpuscles loses as much of its weight as the weight of the volume of fluid displaced. And now, if our soul-being lives in the force of buoyancy, just think what this possession of iron-bearing blood corpuscles must mean for the whole life of feeling and perception, indeed for the whole life of the organism. In other words: If in a given case there is irregularity in what is going on in the blood simply as a result of the buoyancy of the iron-bearing corpuscles, we know that iron in some form or other must be introduced, but in such a way, of course, that the iron will unfold a right action in the blood, and not elsewhere.

In terms of Spiritual Science, this means that the relation of the etheric to the astral organism of man is bound up with the iron-content of the blood. And if we understand how the activities of heart and lungs lead over into the realm of life all that is taken up by the organism, and how the kidneys in turn lead this over into the astral organism, we shall not be far from the realisation that balance must reign here. If there is no balance, if either the etheric or the astral activity becomes too intense, the whole organism is bound to fall into disorder. The possibility, however, of promoting the corresponding balance, of enabling the organism to lead the necessary amount of foodstuff into the domain of the kidney activities, is provided by regulating the iron-content in the blood. And by imbuing the actual dynamic element in the blood either with weight or with the force of buoyancy—according to how we regulate the iron-content—we are thereby regulating the whole circulation of blood, which in turn reacts upon the kidney activities. In adding to or decreasing the iron-content we have brought about a fundamental regularisation of the blood circulation: that is, of the interplay between the etheric and astral parts of man.

And now let us take a concrete case. Suppose we have flatulence as a primary symptom. I am choosing a crude example for the sake of clarity. What does flatulence indicate to one who has insight into the human organism? It indicates the presence of aeriform organisations in which the astral organism is working with excessive strength and which are being dispersed too slowly. They are formations which have been brought about by the astral organism—which works, of course, in the gaseous being of man—and they conglomerate instead of forming and dissolving in the regular way. That is what is happening when flatulence is present. Now because the astral activity is excessively strong it influences the whole activity of the senses, especially the activity of the head. The astral activity congests and does not properly distribute itself in the organism; hence it does not work as it should into the metabolic processes, but turns back to the system of nerves and senses with which it is more closely related. And so we shall very soon find that something is amiss with the system of nerves and senses, too—or at all events we may assume that here is a complex of symptoms where the nerves and senses are not working in the right way. And now I must add something in connection with the irregular working of the nerves and senses.

Physiology really talks nonsense about the nerves and senses. Forgive me for saying this—I am expressing myself radically only in order that we may understand each other. You must take such statements with the familiar ‘grain of salt,’ for if I compromise too much in what I say we shall not find it so easy to understand these things.

Supersensible observation of the human organism reveals that any given function which can be demonstrated in the sense of objective empiricism, is, from the higher point of view, the material reflection of something spiritual. The whole human organism is the material reflection of Spirit. But the interaction between the Spirit and soul and the physical-organic nature of man is by no means so simple in the case of the system of nerves and senses as is generally imagined.

Take the physical organisation of man. It is not true—as many people would like to assume—that with the exception of the nervous system and the senses, the physical organisation constitutes one whole, and that the nervous system is inserted into this structure in order independently to serve the life of soul. That is putting it rather radically, of course, but if we come down to the practical considerations underlying the physiological theory, something of the sort comes to light. That is why it is almost impossible to-day to form any rational opinion of functional diseases, nerve-troubles and the like, as they are often called. There is nothing in the human organism that does not belong to the whole organism; that does not interact with other organs. It is not a question of the rest of the organism being left to its own devices and an independent nervous system being inserted, heaven knows by what divine power, in order that the organism may become soul! Look for evidence of this and you will not need to look far. The nervous system is primarily that from which the formative, rounding-off forces of the organism go out. The form of the nose, the form of the whole organism is shaped, fundamentally, by the influences proceeding from the nervous system. The kidney system radiates out the forces of matter, and the nervous system is there to give the organism its forms, both inwardly and outwardly. To begin with, the nervous system has nothing to do with the life of soul; it is the moulder, the form-giver of the human organism, inwardly and outwardly. In short, the nervous system is the sculptor.

In the early stages of individual development, a certain portion of nerve-activity which the organism does not use for formative functions separates off, as it were, and to this the being of soul adapts itself more and more. That, however, is secondary; we must observe this separation of a part of the nerve-process in very early childhood, and the adaptation of the soul-life to these formative principles, if we are to get down to the empirical facts. There is no question of the nervous system being laid into the human organism as the result of some kind of divine ordinance to form the basis for the life of volition, feeling and thought. The life of nerves and senses comes into being with a sort of hypertrophy, part of which is preserved, and to this the activity of the soul then adapts itself. The primary function of the system of nerves and senses is formative, form-giving. The forms of all the organs are sculptured by the system of nerves and senses.

If you want to verify this, begin by taking the senses that have their seat in the skin, are spread out over the whole skin—the senses of warmth and of touch—and try to envisage how the whole form of the human organism is plastically moulded by these senses, whereas the forms of the special organs are built up by other senses. Sight itself is due to the fact that something remains over from the formative force proceeding originally from the visual tract for the building of the cerebral organs, and then all the psychical elements developed in the faculty of sight adapt themselves to this “something” that has been left over.

We shall never have real insight into the being of man if we do not realise that as metabolism goes on unceasingly within us, day by day, year by year, our organs must first be provided for by all that radiates out from the kidneys, and then rounded off. The substance that is radiated out by the kidneys must continually be rounded off, worked upon plastically. Throughout the whole span of man's life this is done by the nerve-organs which extend from the senses towards the inner parts of the human organism. Higher sense-activity, image-building mental activity and the like, are simply the result of an adaptation of the being of soul to this particular tract of organs.

Now, if flatulence in the complex of symptoms confirms the fact that the astral organisation is working too strongly, this shows that the excessive astral activity is tending in the direction of the formative forces of the senses. In the upward direction and towards the periphery there is not only a congestion of astral activity, but these gas-bubbles, which are really striving to become organs, are rounded off still more completely. In other words, as the result of excessive activity on the part of the kidneys, a continual attempt is being made in the upper man to hold back the Ego-organisation above and not to allow what passes into the organism through the blood to return in the proper way. Hence, associated with the complex of symptoms of which I am now speaking, we shall often find cramp-like conditions, even fits, which are due to the fact that the astral forces are not passing rightly into the rest of the organism. If they are congested above, they do not pass into the other parts of the organism. In these other parts of the organism we notice cramp-like phenomena which are always due to the fact that the astral forces are being held back. In such cases the astral nature is being checked, and by studying a complex of symptoms of this kind in the light of the super-sensible, we can eventually relate the outer facts to their inner causes.

Think of it: the astral is held back above, and as a result the metabolism is drawn upwards; the astral body is not making proper provision for the kidneys, and even less for the stomach; the stomach which is receiving too little from the astral organism begins to fend for itself. Outwardly, there will be colic and cramp-like conditions of the stomach. Again, spasmodic conditions may arise in the sexual organs because they are not properly permeated by the astral organisation, or there may be stoppages of the periods, due to the fact that the Ego-organisation is held back above.

Now let us ask ourselves: How can we influence irregularities of this kind? The best thing, to begin with, is to realise that the magical names given to illnesses merely serve the purpose of conventional understanding; the essential point is to observe what really groups itself together and interweaves among the several symptoms. But we must be able to judge of the nature of these symptoms. Suppose we are considering the function attaching to a flower containing sulphur. If a flower contains a certain amount of sulphur, this means that an active process is on its way to an inorganic state which is still akin to the organic. If we introduce a remedy prepared from such a flower, or even the sulphur produced by the flower, into the human organism, the processes in the digestive tract will be roused to greater activity. The stomach, and subsequently the intestinal activity, will be stimulated by a decoction of flower-petals containing sulphur, because, as I have already said, a process of devitalisation which must be reversed is taking place in the plant. And again, indirectly, the irregularity which has appeared in the action of the kidneys is stimulated to a strong reaction, and we have, to begin with, the possibility of counteracting the congestion above by means of a strong counter-pressure from below. (The forces working here are for the most part only fleeting in their effect, but if we give temporary help to the organism it will usually begin to help itself.) The astral organisation will, as it were, again be drawn into the digestive tract, and the result will be a cessation of the attacks of colic and gastric convulsions. Such a remedy by itself, of course, will suffice only in the rarest cases. It will probably be adequate when the gastric trouble is slight. The organism must never be over-stimulated; whenever it is possible to use a weaker remedy we should avoid a stronger one.

Suppose we have before us a complex of symptoms such as I have just described. The disturbance being very severe, we will assume that demands are being made on the overactive astral body by an excessive activity on the part of the kidneys. The astral body works with undue strength into the sense-organisation, which is thereby weakened and undermined. As sense-organisation it is not really undermined, but the astral organism is working in it so strongly that the formative forces of the nerves and senses are, as it were, smothered by the activities of the astral organism. Neither the sense-organs nor the system of nerves and senses as a whole are in themselves less active, but they do not work in their own characteristic way. They take on, as it were, the organisation of the astral and become as active as the astral organism itself. This means that they are not rightly performing their form-giving functions. We must apply something whereby this astral activity is lifted out of the system of nerves and senses: namely, a remedy that works upon the system of nerves and senses which stands in closest connection with the outer world and which, as organisation, is nearest of all to the inorganic state.

The physiology of the senses is fortunate because in the sense-organs there are so many inorganic, so many purely physical and chemical elements. Think how much in the eye lies in the domain of pure optics. A great deal in the eye can be beautifully depicted if one treats it merely as a kind of photographic apparatus. In saying this I want only to indicate that we are co-ordinated with the outer world precisely through the sense-organs, and that the senses are channels through which the outer world flows into us by way of the inorganic.

Now when it is a question of giving support to this particular activity of the nerves and senses, we can do it very well by introducing silicic acid into the organism, for silicic acid has an affinity with these inorganic activities at the periphery. We drive the astral organisation out, as it were, by means of the forces inherent in everything that underlies the formation of silicic acid, for this inclines so very strongly, even in outer appearance, towards the inorganic state. When silicic acid is present in any flower you will invariably find that the flower is brittle or prickly, pressing on to the inorganic state. Thus we can relieve the sense-organs by administering silicic acid, and also by supplying the organism with more sugar than it has in the ordinary way. Sugar, too, is a substance that is so worked upon in the human organism that it finally comes very near to the inorganic. Thus everything we introduce by way of sugar relieves the sense-organs. If conditions allow, this process can also be strengthened by the administration of alkaline salts, which are well calculated to relieve the nervous system of astral activity. These are matters which should be verified by a series of empirical investigations.

Spiritual Science thus enables us to arrive at guiding principles. With the faculty developed by intuitive knowledge we can perceive, for instance, the after-effects of sugar, particularly in those parts of man's nervous system which run from the central nervous system to the senses; the after-effects of silicic acid tend towards the peripheral activities unfolding in the senses. These things can all be verified and proved. And so, when a severe complex of symptoms such as I have described, is present, we shall find the following of benefit: remedies composed simply of alkaline salts, which do much to relieve the nerve-activity of the astral nature; of sugar (not of course administered in the ordinary amount but in an unusual one); and of silicic acid.

The best remedial effects of these substances will be obtained simply by the administration of a proper preparation of the roots of chamomile. It may surprise you that I speak of a root, but the points of view intersect and we must realise that when the symptoms are severe, sulphur and blossom-products are not efficacious. What we do need is a substance that is contained still in a highly vitalised state in the plant, so that the long process it has to undergo will make the reaction vigorous enough. If we introduce a suitable dosage of these substances, as they are found in the root of the chamomile, into the digestive tract, the reaction in this case will not be strong enough to allow the vitalisation to take place at the point of transition from the intestines to the blood; what is contained particularly in the sugar and silicic acid, but also in the alkaline salts, will simply be forced through in an untransformed state. This gives the kidneys a chance to absorb it into their radiations, and the substances so absorbed are then impelled by the action of the kidneys towards the sphere of activity of the nerves and senses, which are thereby relieved of the astral functions.

If we really have insight into these matters, if we realise that this mode of therapeutic procedure leads to the best results, much can be learnt. Moreover, we can very easily be led to other things. We can see how what is absorbed is transformed in the human organisation: thereupon the activity of the kidneys sets to work, receiving what is supplied to it along the channels of the blood and radiating it out; the plastic activity then reacts in its turn. Then we begin to perceive that this plastic activity in its pure form is restored by the administration of silicic acid, sugar and alkaline salts. To super-sensible vision, silicic acid, alkaline salts and sugar, in the right proportions, form a kind of human phantom; something like a phantom is there before us if we think of these substances in regard to their form-building forces. They are pre-eminently sculptors; they bear the plastic principle within them—as is evident even in their outer formation.

The strong action of silicic acid is due, in the first place, to the fact that when the substance appears in the inorganic realm, it has the tendency to form itself into elongated crystals. The results obtainable with silicic acid could not be reached with substances which have the tendency to develop into rounder, less elongated crystals. With such substances it might conceivably be possible to cure a hedgehog but not a human being, whose very principle of growth shows tendencies to elongation.

Those who have no feeling for this artistry in Nature—an artistry with which the organism is moulded chiefly by the activity of nerves and senses-cannot discover in any rational sense the relations between substances in the outer world and what is taking place in the human organism. Yet there is indeed a rational therapy—a therapy which is able to perceive processes which run their course in the outer world, are broken down, as it were, in the human organism, and can then be radiated out by the kidneys and taken hold of, finally, by the plastic activity of the organisation of nerves and senses.

Let us take another example. Suppose that the radiating action of the kidneys, instead of being too strong, is too weak—that is to say, too little of the foodstuff is being drawn up into the astral organisation.

All that I described in the previous complex of symptoms is due to excessive working of the astral organism. The astral organism is active particularly in the upper man and holds itself aloof from the activities of digestion, heart and lungs; and as an accompanying phenomenon we shall find the formation of phlegm and the like, which is quite easy to understand. Thus in the previous case we have to do with an excessive astral activity.

Now suppose that the astral activity is too feeble. The radiating activity of the kidneys is unduly weak, so that the astral organism is not in a position to supply to the formative, plastic forces what it ought to give them when it enters their domain. The formative force cannot then work itself into the astral organism because the latter does not reach sufficiently to the periphery. The result is that no active contact is established between the formative force and the force proceeding from the circulation of the food-substances and their distribution. The substance is distributed without being taken in hand by the formative force. Insufficient plastic force is unfolded and the substance is abandoned to its own life; the activity of the astral body is too fleeting and does not work properly in the transformation of the substances.

Such a state of affairs may certainly be regarded as a complex of symptoms. How it will express itself? Above all, that which is coursing in the blood-vessels will not be taken up in the proper way by the feeble action of the kidneys; that is, by the astral organisation which is working with insufficient power. It collapses, as it were, resulting in hæmorrhoids or excessive menstruation. The contact fails and the metabolism lapses back into itself. In this condition of the organism it is specially easy for a state of ‘fever of occult origin’—as it is called—to arise, or a condition of intermittent fever.

And now the question is: How can we attack this complex of symptoms? The activity of the astral organism is too feeble. We must stimulate the action of the kidneys in order that sufficient material may be sent up into the astral organism. The best thing to do here is to restore the balance between the etheric and astral organisms. Then, simply on account of what passes from the digestive tract into the system of lungs and heart, we get the proper transition to the activity of the kidneys. We obtain a kind of balance, and in many cases we can control it precisely by regulating the iron-content in the organism which governs the circulation. This will now stimulate a strong, inner activity of the kidneys which will be demonstrated outwardly in a change in the excretions of urea through the kidneys, as well as through the perspiration. This will be quite evident. But of course in very many cases we must realise that this balance is always very delicately poised, and that only in the crudest cases will the remedial agent in question here, which man already bears within him, be of assistance.

Whereas in the digestive tract substances containing sulphur in some form are the most effective, and in the system of nerves and senses (the formative principle) substances such as silicic acid and alkaline salts, pure metals are the substances which regulate the balance between the forces of gravity and buoyancy. We need only try out how they must be applied in order to restore the disturbed balance in the most varied ways. We start from iron. According to the complex of symptoms, the most suitable metal may be gold, or perhaps copper. If the form of disease makes us sure of our ground, highly important results will be obtained from the pure metals. If the interplay between the functions of form-building and the breaking-down of form is such that there is too little form-building and this state of affairs becomes organic—if, therefore, the primary cause of the trouble is that the relation between the system of heart and lungs and the kidney system is upset—we shall achieve the best results with iron.

But if, as the result of lengthy disturbances in the processes, the organs themselves are impaired, and have already suffered from a lack of plastic activity because the plastic forces have not been able to reach them, we may have to apply quicksilver. Because quicksilver already has the forces of form, the durable metallic drop-form within itself, it has a definite effect upon the lower organs of man. In the same way we can discover definite connections between metals and the organs of the head that have been attacked and injured, for instance when the nervous system itself is involved. But here it will be a good thing not to confine ourselves to setting up a stable balance as against the vacillating balance. This is extraordinarily difficult. This balance is just like a very sensitive pair of scales. We try in every possible way to make the scales balance and it is almost impossible. We shall get at it more easily, however, if we do not merely concern ourselves with the balancing, but with the pans themselves. We can give support, for instance, to the working of the iron by introducing sulphur into the digestive tract, and providing a counter-action in the nerves and senses system by means of alkaline salts. Then in the middle, rhythmic system of man we shall have iron at work; potassium, calcium or alkaline salts in the nerves and senses, and sulphur in the rhythm of digestion. That is the better way to set about restoring the balance.

Now the remarkable thing is that we find the very opposite state of affairs in the leaves of certain plants. If, for instance, we prepare the leaf of urtica dioica, the ordinary stinging-nettle, in the right way, we have a remedy composed of sulphur, iron and certain salts. But we must really know how to relate the devitalising force that is present in the plant to the vitalising force that is present in the human organism. In the root of urtica dioica it is indeed true that the whole sulphur-process is tending gradually to the inorganic state. The human organism takes the opposite course, and so transforms the sulphur by way of the albumen that it gradually brings the digestion into order. The iron in urtica dioica works from the leaves in such a way that in the very seed, and thereby once more in next year's leaves, this plant thrusts apart the very thing that brings together the rhythmic process in the human organism. In fact, the stinging power of the nettle leaves is this destructive process that must be overcome if the rhythmic process in the human organism is to be regulated. Again, the alkaline salt content of the plant is least of all transformed into inorganic matter. Therefore it has the longest way to go. It goes right up to the nerves and senses organisation; goes up quite easily because, in any case, with the complex of symptoms we are now considering, the activity of the kidneys is asleep and suppressed. In the human organism we have actually the opposite of what is expressing itself outwardly in the formation of the plants. But there is no need to confine ourselves merely to plant-remedies; synthetic remedies may also be prepared and cures effected by combining the substances I have mentioned in a suitable dosage.

These are matters which will gradually transform therapy into a rational science, but a science that is really an art, for it can no more exclusively be science than a man who is not an artist can be a sculptor. He may have a splendid knowledge of how to guide his chisel and how to mould the clay, but there must always be an element leading over into the realm of art. Without this, true therapy is impossible. We must really get the right touch—in a spiritual sense, of course—for determining the dosage. This will not suit all those who would like to turn medicine into a pure science, but it is true, nevertheless.

And now let me indicate, merely by way of example, another state of affairs that may arise. There may be a disturbance of the interaction between what the organism produces by way of inorganic material, as a preliminary to leading it over into the realm of organic life, and the subsequent intervention of the etheric body and the action of heart and lungs. A disturbance may arise here. The greater the age of a man, the more apparent is the disturbance. The digestive tract and the vascular system are not working properly together. When this sets in, we must remember that the consequence will be an accumulation of the products of metabolism. If the substances are not being properly distributed in the organism, the natural result is an accumulation of the products of metabolism. And here we come to the whole domain of diseases of metabolism, from the very mild to the most severe forms. We must realise that in such cases something is amiss with the activity of the kidneys, too, for the reason that because of the antecedent congestion the kidneys are receiving nothing which they can radiate out.

This gives rise to highly complicated forms of disease. On the one hand the action of the digestion and the kidneys provides nothing by way of material upon which the plastic, form-giving activity can work, and on the other, as the result of a stultification of this plastic activity, we have a disturbance of the organic balance from the other side. The plastic force, too, gradually ceases to function. The products of metabolism spread themselves out in the organism but fail, little by little, to be received into the field of the plastic activities and used as modeling material. And then there arise certain metabolic diseases which are so highly resistant to treatment. The proper course is to stimulate in the digestive tract, and then also in the domain of heart and lungs, all that is akin to elements that are on their way to the inorganic state—akin, that is, to the sulphuric or phosphoric elements connected, in the blossoms of plants, with the ethereal oils. We attempt to stimulate this in the digestive system and in the system of heart and lungs; also we stimulate the activity of the kidneys and thereby help the plastic forces. In this type of disease it is of great importance to bring influence to bear on the digestive apparatus.

Now the activity of the kidneys and the excretion of sweat are in a certain sense polar opposites; in other words they are intimately related to one another. And if, as a consequence of what I have described, the kidneys are not acting properly, we shall always find that there is less perspiration. Great attention should be paid to this, for whenever there is a decrease in the perspiration, we may be sure that something is amiss with the action of the kidneys. What is happening, as a rule, when the perspiration decreases, is that the kidneys are like a machine which has nothing to work upon but continues to act, while the products of digestion are already congested and are spreading unduly over the organism. If by the outer or inner application of sulphur treatments (for we can work just as well from the skin as from the kidneys themselves) we succeed in stimulating the digestive tract to such an extent that it, in turn, stimulates the activity of heart and lungs so that material is again supplied to the kidneys, instead of lying fallow before it reaches them, we may also succeed in getting the better of these diseases of metabolism.

But in all these matters we must be quite clear that the human organism is something that does not want to be absolutely cured, but only stimulated to unfold the healing process. This is a fact of supreme importance. In the state of illness, the human organism wants to be stimulated to unfold the healing process. If the healing is to be permanent we must actually limit ourselves to giving a mere stimulus. For a cure which apparently happens at once leads much more readily to relapses than a cure which merely stimulates the healing process. The organism has first to accustom itself to the course of the healing process, and is then able to continue it by virtue of its own activity. In this way the organism binds itself much more intimately to the healing process, until such time as the reaction again sets in. If for a certain length of time the organism can be made to adjust itself to the healing process, that is the best possible cure, for then the organism actually absorbs what has been transmitted to it.

I have been able only to give you certain hints as to method, but you will realise that in what I call a spiritual-scientific enlightenment of physiology, pathology and therapy, it is a question of understanding that man is not an isolated being but that he belongs to the whole Cosmos, further, that in connection with any process taking place in the human being in an ascending curve, let us say, we must seek outside man, in Nature, for the descending curve. In this way we shall be able to modify curves that are ascending too abruptly. Medicine indeed demands in a certain respect a knowledge of the whole world. I have given only a tiny fragment, but it indicates that there must be an entirely different understanding of the nature of urtica dioica, colchicum autumnale, or indeed of any other plant. The plants themselves must tell us whither their descending tendency is leading.

Take the case of colchicum autumnale, the autumn crocus. First you must perceive when you approach this plant that the time of the year in which it appears is not without significance for its whole structure, for this brings about a certain relation to the devitalising process. That the devitalisation is very slight in colchicum autumnale, you can see from the very colour of its petals and the time of its flowering. If you then experiment with colchicum autumnale, you will find that the human organism must exert itself up to a very high level to bring about the opposite vitalisation, that is to say—if I may express it crudely—to get the plant dead and then alive again. Indeed, this whole process plays right up into the thyroid gland. And now you have the basis for a series of investigations with colchicum autumnale as a remedy for enlargements of the thyroid gland.

Let me assure you once again that there is no question of a profitless, amateurish abuse of modern scientific methods, but rather of giving guiding lines which will actually lead to more tangible results than mere experimentation. I do not by any means say that this cannot also be fruitful. It does indeed lead to certain goals, but a great deal passes us completely by, especially many things we can learn by observing Nature. Although it is not difficult to produce a synthetic preparation composed of iron, sulphur and alkali, it is a good thing to know how all these substances are brought together by Nature herself in a particular plant. Even in the production of synthetic remedies we can learn very much by understanding what is going on in Nature outside.

It would be fascinating to enter into many things in detail, and I think that some of our doctors will have done so in other lectures. A great deal, too, can be found in our literature, and there are many subjects which I hope will soon be dealt with there. I am convinced that as soon as these matters are presented in a clear, concise form and people are not afraid to go straight ahead, they will take this point of view: “Yes, I must above all heal if I want to be a doctor, and so I will turn to what, in the first place, seems rather against the grain. If it really helps, I cannot do otherwise than try to profit by it.”

In this sense I think it would be a good thing if as soon as possible we could produce literature of a kind that would be a bridge between Spiritual Science and modern material science. It would encourage the opinion that these things help and so they cannot after all be such utter nonsense! I am quite sure that when our work is properly in train, the verdict will be that it does indeed help.—And here I will conclude. Try it all out and you will find that it will help. That too, will not be without significance, for many things that are used in orthodox medicine do not help. And between what does and does not help there must play all that we would like to introduce from the side of Spiritual Science.

I must ask my audience to be considerate with me today, because I have just arrived after a very tiring journey and probably will not feel able to speak to you adequately until tomorrow.

I want this first lecture to be a kind of introduction to the series I am to deliver here. I had not really intended to speak during this medical conference, because I think the stimulus given by anthroposophical research to medicine and to natural scientific thinking ought to be worked out by those who are specialists in the various domains. Indeed, all that comes from anthroposophical investigation regarding medicine and, for instance, physiology, can be no more than a stimulus that must then be worked out empirically. Only on the basis of this empirical study can there arise valid and convincing judgments of the matters in question—and this is the kind of judgment that is needed in the domain of therapy.

These lectures, however, are given at the special request of our doctors here, and I shall try to deal with those points where anthroposophy can illuminate the realm of medicine. I shall endeavor to show, first of all, that an understanding of the human being in both health and disease can be enriched and deepened through the anthroposophical view.

By way of introduction perhaps you will permit me to speak of the sense in which the anthroposophical approach should be understood today, in our own age. People so readily confuse what is here called anthroposophy with older traditional ideas about humanity. I have no wish to waste words about the value of these old conceptions or to criticize them in any way, but it must be emphasized that the conceptions I am putting forward are founded on a very different basis from that of the various mystical, theosophical, and gnostic ideas that have arisen traditionally in the course of human history. In order to make myself clear, I need mention only the main points of difference between the conceptions that will be presented here and those of earlier times.

Those earlier conceptions arose in human thought at a time when there was no natural science in our sense; mine have been developed in an age when natural science has not only come into being but has reached a certain—albeit provisional—perfection. This must always be remembered if we wish to understand the meaning and significance of our studies, for it applies to everything that may be said and discovered by anthroposophy about the most varied branches of human knowledge and ability.

You all know—and I don't need to enlarge upon it for you—that in those earlier times man had a non-scientific (in our sense) conception of the super-sensible world. Medicine, too, was permeated with super-sensible conceptions, with conceptions of the human being that did not originate, as is the case today, from empirical research. We need go back only to the age shortly before that of Galen, and if we are open-minded enough we shall find everywhere spiritual conceptions of the being of man on which medical thought, too, was based. Permeating these conceptions of the form of the human being, the form of his organs and of human functions, were thoughts about the super-sensible. According to our modern empirical way of thinking, there are no grounds for connecting anything super-sensible with the nature and constitution of the human being, but in those older conceptions the super-sensible was as much a part of human nature as colors, forms, and inorganic forces now seem to us bound up with the objects in the outer world.

Only a person with preconceptions will speak of those earlier ages in the development of medicine as if its ideas were merely childish, compared with those that have evolved today. Nothing could be more inadequate than what history tells us in this connection, and anyone who has the slightest understanding of the historical evolution of humanity, who does not take the point of view that perfection has been reached and that everything earlier is mere foolishness, will realize that even now we have arrived only at relative perfection and that there is no need to look back with a supercilious eye upon what went before. Indeed, this is obvious when we consider the results that were achieved. On the other hand, an individual concerned with any branch of knowledge today must never overlook all that natural science has accomplished for humanity in this age. And when—to use the Goethean expression—a spiritual way of considering the human being in sickness and health wishes to become active today, it must work with and not against natural scientific research.

After what I have said I hope you will not accuse me of wishing to cast aspersions on the concepts of natural science. Indeed, I must emphasize at the beginning that such a thing is out of the question and for a very fundamental reason. When we consider the medical views that were held in an earlier period of civilization, we find that although they were by no means as foolish as many people believe nowadays, they did lack what we have gained through natural science, for the simple reason that man's faculty of cognition was not then adapted to see objects as we see them today by means of our senses and the products of empirical thought. The doctor (or I might just as well say the physiologist or biologist of ancient times) saw in an entirely different way from the way modern man sees. In the times that really come to an end with Galen, medical consciousness had quite another orientation. What Galen saw in his four elements of the human organism, in the black and yellow gall, in the phlegm and in the blood, was utterly different from what the human being sees today.

If we understand Galen's words—as a rule, of course words handed down from ancient times are not understood—then what he describes appears nebulous today. He saw as a reality what to us appears nebulous; in what he called phlegm he did not see the substance we call phlegm. To him phlegm was not only a fluidity permeated with life but a fluidity permeated with soul. He saw this. He saw this as clearly as we see something as red or blue. But precisely because he was able to see something outside the range of modern scientific consciousness, Galen was not able to see many things that are brought to light today by our scientific consciousness.

Suppose, for example, that a man with slightly abnormal vision looks through glasses, and by this means the contours of objects become sharper than they would otherwise appear to him. In the same way, as the result of modern empiricism all that was once seen hazily, but nonetheless permeated by spirit and soul, has disappeared and been replaced by the sharp contours of our modern empirical observation. The sharp contours were not there in ancient times. Healings were performed out of a kind of instinct that was bound up with an intense development of human compassion. A sort of participation in the patient's disease, which could even be painful, arose in the doctor of ancient times, and on the basis of this he set about his cure. The sharp boundaries that we perceive today through our empiricism based in the senses were not seen at all.

Because the advance to this sense-oriented empiricism is rooted in the evolution of man, we cannot merely brush it aside and return to the old. Only if we develop certain atavistic faculties will we perceive nature as the ancients perceived her, in all domains of knowledge, including that of medicine. In our modern civilization, when we grow up equipped with the kind of training given in our lower schools—not to speak of higher education—it is simply impossible to see things as the ancients saw them; moreover, if a person did see things in this way he would be regarded as being if not gravely, at any rate mildly psychopathic, not quite “normal.” Indeed, this would not be altogether unjust, for there is something psychopathic today in all instinctive “clairvoyance,” as it is called. We must be quite clear about this. What we are able to do, however, is to work our way up to a perception of the spiritual by developing inner faculties otherwise latent in the soul, just as in the course of evolution the eye has evolved itself from indefinite vision to sharply contoured vision.

Today, then, it is possible to develop faculties of spiritual perception. I have described this development in my book, Knowledge of the Higher Worlds and How to Attain It, and in my other writings. When an individual has developed these faculties, he sees, to begin with, a world not previously visible to him, a world encompassing a kind of spiritual cosmos beyond the cosmos revealed to sense perception today, including the discoveries and calculations of astronomy. To the sense-perceptible cosmos that is permeated by natural law, a spiritual cosmos is added. And when we seek to discover what exists in this spiritual cosmos, we also find the human being. We take hold of a spiritual universe, a universe permeated with soul and spirit, and we see the human being as a member of this universe.

If we pursue ordinary natural science, we begin either with the simplest living being or with the simplest form of life—the cell—and then trace the simple on into the more complex, ascending thus from what most resembles purely physically organized substance to the highly intricate human organism. If we are seriously pursuing spiritual science, we begin at the other end. We descend from a comprehension of the spiritual in the universe, regarding this as complex, and we look at the cell as the simplest thing in the organism. Viewed in the light of spiritual science, the universe is the summit of complexity, and just as we gradually elaborate the elements of our own cognition in order, let us say, to pass from the cell to the human being, so we progressively simplify what the cosmos reveals and then come to the human being. We follow an opposite path—that is to say, we begin at exactly the opposite starting point—but when we pursue spiritual science today in this way, we are not at first led all the way into the regions encompassed by modern material empiricism. I wish to stress this point strongly and hope that there will be no misunderstanding particularly regarding these fundamentals. This is why I must ask you today to forgive these somewhat pedantically formed concepts.

It is quite conceivable that someone might think it useless to adopt the methods of empirical thought in physiology or biology. “What need is there for any specialized branch of science?” he might ask. “One develops spiritual capacities, looks into the spiritual world, arrives at a view of man, of the being of man in health and disease, and then it is possible to found a kind of spiritualized medicine.” This is just the kind of thing many people do, but it leads nowhere. They abuse empirical medicine, but they are abusing something they do not understand in the least. We should not even consider writing off ordinary sense-oriented empirical science as worthless and taking refuge in a spiritualized science brought down from the clouds. That is quite the wrong attitude to adopt.

Spiritual scientific investigation does not lead to the same things that are examined under the microscope. If anyone tries to pretend that with the methods of spiritual science he has found exactly the same things he finds under a microscope, he may safely be summed up as a charlatan. The results of modern empirical investigation are there and must be reckoned with. Those who seriously pursue science also in the sense of spiritual scientific anthroposophy do not simply depart from sense-oriented empiricism; it is necessary to take such empiricism into account. One who might be called an expert in an anthroposophical spiritual science must first concern himself with the phenomena of the world in the sense of ordinary empiricism.

From spiritual science we discover at first certain guidelines for empirical research, certain ruling principles, showing us, for instance, that what exists at a particular place in the organism must be studied also in reference to its position. Many people will say, “Yes, but a cell is a cell, and purely empirical observation must determine the distinguishing feature of this cell—whether it is a liver cell or a brain cell and so on.” This is not the case. Suppose, for example, I walk past a bank at nine o'clock in the morning and see two men sitting there side by side. I look at them and form certain judgments about various things in relation to them. At three o'clock in the afternoon it happens that I again walk past the bank. There are the two men, sitting just as before. The empirical state of affairs is exactly the same in both cases, allowing for very slight differences. But now, think of it: one of the men may have remained sitting there for the whole six hours. The other may have been sent out on quite a journey right after I first passed the bank and may have just returned. This essentially alters the picture and has nothing to do with what I actually perceive with my senses. As far as my senses are concerned, the same state of affairs presents itself at nine o'clock in the morning and three o'clock in the afternoon, but the state of affairs determined by sense observation must be judged in accordance with its constituents.

In this sense our conception of a liver cell must differ essentially from our conception of a cell in the brain or the blood. Only if it were correct to say, for the sake of example, that the basis of everything is a primeval germ cell that has been fertilized and that the whole organism can be explained by a process of simple division and differentiation of this primeval germ cell—only then could we proceed to treat a liver cell exactly the same as a brain cell in accordance with the purely empirical facts. Yes, but now suppose that this is by no means correct, that by virtue of its very position in the organism the relation of a liver cell to forces outside man, outside the bounds of the skin, is not at all the same as the relation of a brain cell to these forces. In that case it will not be correct to look on what is happening merely as a continuation of the process of division and subsequent location in the body. We must rather assume that the relation of the brain cell to the universe outside is quite different from that of the liver cell.

Suppose someone looks at the needle of a compass, finds it pointing from South to North, from North to South, and then decides that the forces that set the needle in the North-South direction lie in the needle itself. He would certainly not be considered a physicist today. A physicist brings the needle of the compass into connection with what is called earthly magnetism. No matter what theories people evolve, it is simply impossible to attribute the direction of the needle to forces lying within the needle itself. It must be brought into relation with the universe.

In studying organic life today, the relationship of the organic to the universe is usually regarded as quite secondary. But suppose it were indeed true that merely on account of their different positions the liver and the brain are actually related quite differently to universal forces outside the human being. In that case we could never arrive at an explanation of the human being by way of pure empiricism. An explanation is possible only if we are able to say what part the whole universe plays in molding the brain and the liver, in the same sense as the earth plays its part in the direction taken by the needle in the compass.

Suppose we are tracing back the stream of heredity. We begin with the ancestors, pass on to the present generation, and then to the offspring, both in the case of animals and of human beings. We take into account what we find—as naturally we must—but we reckon merely with processes observed to lie immediately within the human being. It hardly ever occurs to us to ask whether under certain conditions in the human organism it is possible for universal forces to work in the most varied ways upon the fertilized germ. Nor do we ask: Is it perhaps impossible to explain the formation of the fertilized germ cell if we remain within the confines of the human being himself? Must we not relate this germ cell to the whole universe?

In orthodox science today, the forces that work in from the universe are considered secondary. To a certain limited extent they are taken into consideration, but they are always secondary. And now you may say: “Yes, but modern science leads us to a point where such questions no longer arise. It is antiquated to relate the human organs to the universe!” In the way in which this is often done, it is antiquated, but the fact that generally such questions do not arise today is due entirely to our scientific education. Our education in science confines us to this purely sense-oriented empirical mode of research, and we never come to the point of raising questions such as I have posed hypothetically by way of introduction. But the extent to which man is able to advance in knowledge and action in every sphere of life depends upon raising questions. Where questions never arise, a person is living in a kind of scientific fog. Such an individual is himself dimming his free outlook upon reality, and it is only when things no longer fit into his scheme of thought that he begins to realize the limitations of his conceptions.

I believe that in the domain of modern medicine there may be a feeling that the processes taking place in the human being are not wholly reconcilable with the simple, straightforward theories upon which most cures are based. There is a certain feeling that it must be possible to approach the whole subject from another angle. And I think that what I will have to say in this connection will mean something especially to those who are specialists in their particular branches of science, who have practical experience of the processes of health and disease and have realized that current conceptions and theories are everywhere too limited to grapple with the complexity of the facts.

Let us be quite honest with ourselves in this regard. During the entire nineteenth century a kind of axiom was put forward by nearly every branch of scientific and practical thought. With a persistence that was enough to drive one to despair, it was constantly being said, “Explanations must be as simple as possible.” And that is just what people tried to do. But if facts and processes are complicated, it is prejudging the issue to say that the explanations must be simple. We must accustom ourselves to deal with complexities. Unspeakable harm has been done in the realms of science and art by the insistent demand for simplification. In all her manifestations, small and great, nature is not simple but highly complicated. We can really grapple with nature itself only if we realize from the outset that the most seemingly comprehensive ideas are related to reality in the same way that photographs of a tree, taken from one side only, are related to the tree. I can photograph the tree from every side, and the photographs may be very different under different circumstances. The more photographs I have, the more nearly will my mental image approach the reality of the tree.

The prevalent opinion today is this: such and such a theory is correct. Therefore some other theory—one with which we do not happen to agree—must be wrong. But that is just as if a person were to photograph a tree from one side only. He has his particular photograph. Someone else takes a photograph from another side and says to the first person, “Your photograph is absolutely false; mine, and mine alone, represents the truth.” He claims his particular view to be the correct one. All controversies about materialism, idealism, realism, and the like have really taken this form. The squabbles in such realms are by no means different from the seemingly trivial example I have given as a comparison. At the very outset of our studies I ask you not to take what I have to say as if it were meant to tend in the direction of materialism, idealism, or spiritualism, but merely as an attempt to go straight for reality to the extent to which the capacity of human thought permits. If we wish to master what is real, we can occasionally achieve tremendous results with materialistic conceptions if we are then able to introduce the opposite aspect into our considerations. If it is impossible to keep the various aspects separate, our ideas will appear as if we took many different photographs all on the same piece of film. Indeed, many things are like this today. It is as if photographs from many different aspects had been taken on the same piece of film. Now when the forces lying latent in the soul of man are realized by the methods outlined in my book, Knowledge of the Higher Worlds and How to Attain It, we rise above the ordinary standpoint of knowledge—to which the latest phase in biology pays special attention—and reach what I have described as Imaginative cognition or knowing. A still wider standpoint is that of Inspired knowing, and the highest, if I may use this expression, is that of the Intuitive, of real Intuitive knowing. In Imaginative cognition, I receive pictures of reality, knowing very well that they are pictures, but also that they are pictures of reality and not merely dream-pictures. In Imaginative cognition I do not have reality yet, but I have pictures of a reality. At the stage of knowing by Inspiration, these pictures acquire a certain consistency, a viscosity, something lives within them; I know more through the pictures than the pictures alone yielded me. I know by means of the pictures that they are related to a spiritual reality. And in the acts of Intuitive knowing I stand within this spiritual reality itself. This is the ascent through the three stages described in Knowledge of the Higher Worlds and How to Attain It.

Now these three modes of higher knowledge give us, to begin with, knowledge of spiritual worlds, a knowledge that goes beyond ordinary, sense-oriented factual knowledge. They give knowledge of a spiritual universe and of man as a soul-spiritual being; they do not, in the early stages, reveal to us today's findings of empirical research in the realm of, say, biology. When Imagination, Inspiration, or Intuition is used to gain understanding of the being of man, a different approach is applied.

Take, for instance, the structure of the human brain. Perhaps it does not strike physiologists and doctors as very extraordinary, but to those who call themselves psychologists it is remarkable. Psychologists are a strange phenomenon in our civilization because they have managed to develop a science without subject matter—a psychology without a soul! For the psychologist this structure of the brain is very remarkable. Think for a moment of a psychologist who takes his start purely from empirical science. In recent times it has been impossible to distinguish whether a philosopher knows something or not. Natural scientists, however, are always supposed to know something, and so in modern times certain scientists who dabble in philosophy have been given Chairs of Philosophy. Current opinion has been this: natural scientists must have some knowledge, because although it is quite possible in philosophy to talk around and around a subject, it is not possible in natural science to spout hot air about something that has been observed under a microscope, through a telescope, or by means of x-rays. All these things can be tested and proven, but in philosophy it is not so easy to prove whether or not a man is speaking out of the clouds.

Think of how Theodor Ziehen speaks about the structure of the brain. In this connection I once had a very interesting experience, and perhaps I can make the point more concrete by telling you an anecdote. Many years ago I attended a meeting where an eminent doctor was lecturing about the life of soul in connection with the brain and its structure. The chairman of the meeting was a follower of Herbart, and he, therefore, was not concerned with analyzing the structure of the brain but the conceptual life, as Herbart, the philosopher, had once done. The chairman then said, “Here we have something very remarkable. The physiologist or the doctor makes diagrams and figures of the structure of the brain. If I, as a Herbartian, make drawings of the complicated association of ideas—I mean a picture of the ideas that associate and not of the nerve fibers connecting one nerve cell with another—if I, as a genuine Herbartian who does not concern himself with the brain as a structure, make symbolic diagrams of what I conceive to be the process underlying the linking together of ideas, my drawings look exactly the same as the physiologist's sketches of the physical structure of the brain.”

This comparison is not unjustified. Natural science has taught us more and more about the structure of the brain. It has been proven in ever greater measure that the outer structure of the brain does, indeed, correspond in a marvelous way with the organization of our conceptual life. Everything in the conceptual life can be found again in the structure of the brain. It is as if nature herself—please take this with a grain of salt—had intended to create in the brain a sculptural image of man's conceptual life. Something of the kind strikes us forcibly when we read statements like those of Meynert (which nowadays are already considered rather out of date). Meynert was a materialist but an excellent neurophysiologist and psychiatrist. As a materialist, he offers us a wonderful contribution to what is discovered when the actual human brain is left out of account and we deal only with the way in which mental images unite, separate, etc., and then sketch these symbols. In short, if anything could make a person a materialist it is the structure of the human brain. In any event it must be conceded that if the spirit and soul do indeed exist, they have an expression so perfect in the human brain that one is almost tempted to ask why the spirit and soul in themselves are necessary for the conceptual life, even if people do still long for a soul that can at least think. The brain is such a true mirror-image of the soul-spiritual—why should the brain itself not be able to think?

All these things must of course be taken with the well-known grain of salt. Today I only wish to indicate the tenor of our studies as a whole. The human brain, especially when we undertake detailed research, is well calculated to make us materialists. The mystery that really underlies all this clears up only when we reach the stage of Imaginative knowledge, where pictures arise, pictures of the real spiritual world not previously visible. These pictures actually remind us of the configurations in the human brain formed by the nerve fibers and nerve cells.

What, then, is this Imaginative cognition, which naturally functions entirely in the super-sensible world? If I attempted to give you a symbolic representation of what Imaginative knowledge is, in the way that a mathematician uses figures to illustrate a mathematical problem, I would say the following: imagine that a person living in the world knows more than sense-cognition can tell him because he can rise to pictures that yield a reality, just as the human brain yields the reality of the human soul. In the brain, nature itself has given us as a real Imagination, an Imagination perceptible to the senses, something that is attained in Imaginative knowledge at a higher level.

This, you see, leads us more deeply into the constitution of the human being. As we shall see in the next few days, this marvelous structure of the human brain is not an isolated formation. Through Imagination we behold a world, a super-sensible world, and it is as though a part of this world had become real in a lower world; in the human brain we behold a world of Imagination in concrete fact. I do not believe that anyone can speak adequately about the human brain unless he sees in its structure an Imaginative replica of the life of soul. It is just this that leads us into a dilemma when we take our start from ordinary neurophysiology and try to pass to an understanding of the life of soul. If we confine ourselves to the brain itself, a life of soul over and above this does not seem necessary. The only individuals with a right to speak of a life of soul over and above the structure of the human brain are those who have knowledge of it other than what is acquired by customary methods in this world. For when we come to know this life of soul in the spiritual world, we realize that it has its complete reflection in the structure of the human brain, and that the brain, moreover, can do everything that the super-sensible organ of soul can do by way of conceptual activity. Down to its very function the brain is a mirror-image. With neurophysiology, therefore, no one can prove or disprove materialism. It simply cannot be done. If the human being were merely a being of brain, he would never need to say to himself, “Over and above this brain of mine, I possess a soul.”

In contrast to this—and I shall now describe in an introductory way something that will be developed in the following lectures—let us turn to a different function of the human being, not the conceptual life but the process of breathing, considered functionally. Think of the breathing processes and what comes into human consciousness with regard to them; with these you will not come to something similar in the organism, as you did regarding the conceptual life. When you say to yourselves, “I have an idea that reminds me of another idea I had three years ago, and I link the one to the other,” you may well be able to make diagrams (especially if you take a series of ideas) that bear a great resemblance, for instance, to Meynert's sketches of the structure of the brain. Now this cannot be done when you try to find an expression in the human organism for what is contained in the breathing processes. You can find no adequate expression for the breathing processes in the structures and formations of the physical organs, as you were able to for the conceptual life in the brain. The breathing processes are something for which there is no adequate expression in the human organism, in the same sense as the structure of the brain is an adequate expression for the conceptual life, the perceptual life.

In Imaginative knowledge pictures arise before us, but if we rise to knowledge by Inspiration, reality streams through the pictures from behind, as it were. If, then, we rise to Inspiration and gaze into the super-sensible world in such a way that the Imaginations teem with spiritual reality, we suddenly find ourselves standing in something super-sensible that has its complete analogy in the connection between the breathing processes, the structure of the lungs, the structure of the arachnoidal space, the central canal of the spinal cord, and the penetration of the impulse of the breath into the brain. In short, if you rise to Inspiration, you learn to understand the whole meaning of the breathing process, just as Imaginative knowledge leads to an understanding of the meaning of the structure of the brain. The brain is an: Imagination made concrete; everything connected with breathing is an Inspiration made real, an Inspiration brought down into the world of the senses. One who strives to reach the stage of Inspired knowledge is transplanted into a world of spirit and soul, but this world lies there tangibly before him when he observes the whole breathing process and its significance in the human organism.

Imagination, then, is necessary for an understanding of the structure of the brain; Inspiration is necessary in order to understand the rhythm of breathing and everything connected with it. The relation of the breathing rhythm to the universe is quite different from that of the brain's structure. The outer, sculptural structure of the brain is so completely a mirror-image of the spiritual that it is possible to understand this structure without penetrating deeply into the super-sensible world. Indeed, we need only rise to Imagination, which borders quite closely on ordinary cognition. The breathing process cannot be understood by means of Imagination; here you must have Inspired knowledge, you must rise higher in the super-sensible world.

To understand the metabolic process one must rise still higher in the super-sensible world. The metabolic process is really the most mysterious of all processes in the human being. The following lectures will show that we must think of this metabolic process quite differently from the way in which it is thought of today in empirical physiology. The changes undergone by the substances as they pass from the tongue to the point where they bring about something in the brain cells, for instance, cannot, unfortunately, be followed by means of merely empirical research but only by means of Intuitive knowledge. This Intuitive knowledge leads us beyond the mere perception of the object into the object itself. In the brain, the spirit and soul of man create for themselves a mere image of themselves but otherwise remain outside this image. Spirit and soul permeate the breathing rhythm but constantly withdraw again. In the metabolism, however, the human spirit and soul immerse themselves completely so that as spirit and soul they even disappear. They are not to be found—nor are they to be found by empirical research.

And now think of Theodor Ziehen's subtle descriptions of the structure of the human brain. It is also possible, in fact, to make symbolic pictures of the memory in such a way that their physiological-anatomical counterparts in the brain can be pointed out. But when Ziehen comes to the sentient processes of feeling, there is already a hitch, and that is why he does not speak of feelings as independent entities but only of mental images colored with feeling. And modern physiologists no longer speak about the will at all. Why? Of course they say nothing! When I want to raise my arm—that is to say, to enact an act of will—I have, first of all, the mental image. Something then descends into the region that, according to current opinion, is wholly “unconscious.” Everything that cannot be actually observed in the life of soul, but is nonetheless believed to be there, is thrown into the reservoir of the “unconscious.” And then I observe how I move my hand. Between the intention and the accomplished fact lies the will, which plays right down into the material nature of the physical organism.

This process can be followed in detail by Intuition; the will passes down into the innermost being of the organism. The act of will enters right into the metabolism. There is no act of will performed by physical, earthly man that cannot be traced by Intuitive knowledge to a corresponding metabolic process. Nor is there any process of will that does not find its expression in disintegration or dissolution—call it what you will—within the metabolic processes. The will first removes what exists somewhere in the organism in order that it may unfold its own activity. It is just as if I were to burn up something in my arm before being able to use this limb for the expression of my will. Something must first be done away with, as we shall see in the following lectures. I know that this would be considered a terrible heresy in natural science today, but nevertheless it will reveal itself to us as a truth. Something substantial must be destroyed before the will can come into play. Spirit and soul must establish themselves where substance existed. This is the essence of Intuitive knowledge, and you will never be able to explain the metabolic processes in the human being unless you investigate them by means of this knowledge.

These three processes—the nerve-sense process, the rhythmic processes (processes of breathing and blood circulation), and the metabolic processes—encompass fundamentally every function in the human organism. Man is really objective knowledge, knowledge made real—regardless of whether we merely observe him from outside or dissect him. Take the human head. We understand what is going on in the head when we realize that it yields Imaginative knowledge; the processes in the rhythmic system become clear when we know that it yields knowledge by Inspiration; we understand the metabolic processes when we know what Intuitive knowledge is. Thus the principles of reality interpenetrate in the human being. Take, for example, the specific organs of the will—they can be understood only by Intuitive knowledge.

As long as we apply a uniformly objective mode of cognition to the human being, we shall not realize that, in fact, he is not at all as he is usually assumed to be. Modern physiology knows, of course, that to a great extent the human being is a column of fluid. But now ask yourselves quite honestly whether physiology does in fact reckon with the human being as a column of fluid, or whether it does not proceed merely as if he were a being consisting of sharply contoured solid forms. You will probably have to admit that little account is given to the fact that he is essentially a fluid being and that the solids have merely been inserted into this fluid. But the human being is also an airy, gaseous being, and a being of warmth as well.

The solid part of the human being can well be understood by means of ordinary objective knowledge. Just as in the laboratory I can become familiar with the nature of sulphide of mercury, so by chemical and physical investigation of the human organism I can acquaint myself with all that is solid. It is different with the fluids in the human being. The fluids live in a state of continual integration and disintegration and cannot be observed in the same way as the stomach or heart are observed and then drawn. If I make drawings of these organs as if they were solid objects, a great deal can be said about them, but it is not the same if we really take seriously this watery being of man. In the fluids something is always coming into being and disappearing again. It is as if we were to conceive of the heart as continually coming into being and disappearing, although the process there is not a very rapid one. The watery being of man must be approached with Imagination.

We must also consider what is gaseous, what is aeriform in us. It is known, of course, how the functions that take place in the aeriform are greatly significant in the organism, it is known how to and from everywhere the aeriform substances in the human organism are in movement, how everything connected with the aeriform is in circulation. When one region of the aeriform interacts with another, however, it follows precisely the pattern of Inspiration. Only through Inspiration can the airy part of the human being be understood.

And now let us pass to the warmth realm in the human being. Try to realize that the human being is something very special by virtue of the fact that he is a structure of warmth, that in the most varied parts of his structure warmth and cold are found present in the most manifold ways. Before we can realize how the human being lives with his ego in his own warmth, we must ourselves live into the process. There must be an act of Intuitive knowledge.

Before you are able to know the whole human being, in his totality—not as if he were simply a mass of solid organs with sharp contours—you must penetrate into the human being from many different angles. Just as we are led from Imagination to Inspiration to Intuition as we pass from the brain to the other organic structures, so it is when we study the different aggregate states of matter within the human being. The solid part of the human being, his solid bodily nature, hardly differs at all within the human organism from the state in which substances exist outside the human organism. There is an essential difference, however, in the case of what is fluid and gaseous, and above all in the case of the warmth. This will have to be considered in the next lectures. But it is indeed a fact that only when our study of the human being widens in this way do we come to know the real significance for knowledge of the organs within human nature.

Sense-oriented, empirical physiology hardly enables you to follow the functions of the human organism further than the point where the chyle passes from the intestines into the lymphatic vessels. What follows is merely a matter of conjecture. All ideas about the subsequent processes that take place with the substances we take in from the outside world, for instance the processes in the bloodstream, are really nothing but fantasy on the part of modern physiology. The part played in the organization by the kidneys, for example, can be understood only if we observe the catabolic processes side by side with the anabolic processes, which today are almost invariably regarded as the only processes of significance for the human constitution. A long time ago I said to a friend, “It is just as important to study those organs which are grouped around the germ of the human embryo, and which are later discarded, as to study the development of the human germ itself from conception to birth.” The picture is complete only when we observe the division of the cells and the structure arising from this division, and also trace the catabolic processes that take their course side by side with the anabolic processes. For we do not have this catabolic process around us only in the embryonic period; we bear it within us continually in later life. And we must know in the case of each single organ to what extent it contains anabolic and to what extent catabolic processes. The latter are, as a general rule, bound up with an increase of consciousness. Clear consciousness is dependent on catabolic processes, on the disintegration, the destruction, the removal of matter.

The same must be said about the processes of elimination. The kidneys are organs of elimination. But now the question arises: although from the point of view of sense-oriented empiricism the kidneys are primarily organs of elimination, have they no other significance in the constitution of man beyond this? Do they not, perhaps, play a more important part in building up the human being by virtue of something other than their functions of elimination? If we then follow the functions still further, passing from the kidneys to the liver, for example, we find this interesting phenomenon: the kidneys ultimately excrete outward, the liver inward. And the question arises: How is the relation of the kidney process to the liver process affected by the fact that the kidneys send their products of elimination outward and the liver inward? Is the human being at one time communing with the outer world, as it were, and at another time with himself?

Thus we are led to a gradual penetration of the human organization, but to assist us in this penetration we need to consider matters that are approached in the ways of which I have given only hints today. I will proceed from this point in the next lecture, showing how these things lead to a real understanding of pathology and therapy, and to what extent they may become guiding principles in the empirical research acknowledged today. This does not imply an attack on such research. The only object is to show that guiding principles are necessary for it to attain its true value.

I am not out to attack natural scientific research or scientific medicine in any sense. My aim is simply to show that in this natural scientific medicine there is a mine of opportunity for a much wider knowledge than can be attained by modern methods and above all by the current outlook of the world. We have no wish to scoff at the natural scientific mode of observation but on the contrary to give it a true foundation. When it is founded upon the spirit, then, and only then, will it assume its full significance.

Tomorrow I will speak further on this subject.
