Basically Spiritual Science aims at understanding humanity in its essence, tasks, and strivings in the course of evolution. We have often talked about how the outside world misunderstands our spiritual science. This is largely because people nowadays have a hard time getting used to certain fundamental truths—truths that simply must be perceived and acknowledged if we are to understand the life and nature of humanity at all.

Let us begin today by asking what modern scientific thinking, whose great and significant triumphs over the last four centuries we must fully acknowledge and appreciate, is based on. It is based on what it can perceive, on what is manifest, in physical existence. Now, of course, it goes without saying that first we trust in what we perceive as so-called reality in our environment, and then we try to explain this reality on the basis of all that we find within its domain. It is naturally difficult for us to be aware at the outset that this reality itself may well contain an element of semblance or illusion, that it may well be deceiving us. Those who truly want to understand spiritual science must first overcome this stumbling block. They must realize that the reality around us can indeed deceive us—it can mislead us into interpreting it falsely. Much of what we have learned in spiritual science over the years has convinced us that immediate reality, as it surrounds us, may indeed be deceptive.

Today we will start from a particular point that can only be reached through spiritual science. In spiritual science we must first understand things; then, when we have understood them, we can find them confirmed in reality. Some of the most important things in spiritual science must first be understood before they can be seen. It would be easy to show that this same method is frequently applied in the outer world, notably in the sciences, but we will not go into that today. It is not always possible to develop everything from the beginning.

Now one aspect of the outer appearance or physiognomy of reality that is most apt to deceive us about this reality is the differences, the diversities among human beings. When we look at the human beings inhabiting the earth, we realize that no two of them are alike on the physical plane. Here in the physical realm all human beings are different from one another. Once we have accepted this diversity of human beings as a fact—I mean the diversity of their physical bodies—it is quite natural that people then try to find out, on the basis of the facts of earthly life, why human beings are different, why they look so different.

However, from the point of view of spiritual science we see something very different. According to spiritual science, if we consider only the forms the physical body can take through the forces of the earth, we find that human beings could not be different but rather would all have to be alike and have the same outer form. Indeed, the forces that exist on earth to give us our physical shape are such that if only these formative forces were to work on us, we would all have the same outer, physical form. This is because the physical human body has undergone a long preparation. We know it was prepared through the epochs of Saturn, Sun, and Moon.¹ It was prepared by forces that worked during these three epochs in such a way that the forces of the earth itself could influence our physical body in no other way than to give it a uniform shape if they had indeed been the only forces at work. I might put it this way: Through all the forces that have been incorporated into our physical body during the Saturn, Sun, and Moon epochs, we human beings are so fortified against any diversities coming from earthly forces that if we were left to the earthly forces alone, we would be alike everywhere on earth. Spiritual science, therefore, must start from the fact that a single and uniform shape is predestined for humanity so far as the terrestrial forces are concerned.

Even if we consider just the difference between male and female what I have just said is true. This difference is not caused by the work of earthly forces; it is the result of quite other forces, which we will speak of presently. Thus, we can assume a certain totality of earth forces that works formatively upon human beings and wants to produce absolutely identical human forms everywhere on earth.

Of course, we must now ask why human beings are so different after all. We know we must consider not only our physical body, but also the etheric body that stands behind it. Spiritual science shows us that while we should all be alike in our physical body, in regard to our etheric body we must be different because earthly forces are not the only ones that work on our etheric body. Forces coming out of the cosmos work on our etheric body, forming and shaping it.

We must therefore distinguish between the uniform earthly forces working all over the earth that would make all human forms the same and the forces working out of the universe on the earth, making each etheric body different. We can see the differences between etheric bodies through spiritual scientific research. At the one extreme are those etheric bodies that have strong forces and are tough, retaining their form almost as much as we do our physical form. This is one kind of etheric body. There is a second kind that is mobile, like something that is fluttering and always in movement, flowing and moving. But these two kinds of etheric bodies still reveal themselves in such a way that we can describe their inner tone and shading as being more or less alike. There is another kind of etheric body that is inwardly tinted, inwardly shimmering, not uniform in color but having various tones and colors. There is a fourth kind of etheric body that has one primary color throughout its whole substance, but this color changes over time though we cannot pinpoint other than purely inward causes for this. These etheric bodies are not shimmering in different colors or shaded in many tones; they have only one color, but they change it in the course of time. We may call them chameleon-like etheric bodies.

Then there are those etheric bodies that have a strong tendency to light up inwardly, growing at times brighter and brighter. Other etheric bodies have a powerful faculty to reproduce the harmonies of the spheres. Finally, there are those etheric bodies that appear especially in inventive people and persons of genius—etheric bodies that, if I may say so, reveal forces within them that are rare and strange in this earthly world. Whereas the above-mentioned six kinds of etheric bodies are found among ordinary, even average, human beings, the last kind of etheric body produces the type of human being with powerfully developed faculties, those we often say are “not of this earth”—poets, artists, and the like.

It is not by arbitrarily picking the number seven that we distinguish these seven forms of etheric bodies. We simply have to count, and we find no others besides those I have just described as typical. For this simple reason, there are seven kinds of etheric bodies. There are seven different kinds of human etheric bodies, and in the etheric bodies we have forces that are not earthly, but come in from the cosmos.

Our etheric body forms and molds the physical body. If only earthly forces worked on us, we would all be alike in our physical body. However, the influence of the etheric body makes us different. The astral body brings about further differences, such as those between male and female bodies, through forces it develops between death and a new birth, during the time when we prepare ourselves for the gender that karma requires us to have in the next incarnation.

But for the moment, let us just look at the etheric body. If we take only earthly forces into account, we can say that our physical bodies would have to be alike. However, because our etheric bodies differ in their constitution, composition, and structure in the cosmos, there would have to be seven groups of human beings. This is the fact we gradually arrive at when we investigate the relationship between our etheric body and our physical body with the methods of spiritual science. Now this difference is connected with the racial diversities on the earth. Basically, because of this difference in etheric bodies, the several races can always be reduced to the number seven. Even though certain typical forms atrophy, and though natural science may distinguish fewer than seven basic races, there are really seven basic racial distinctions in the human species. These diversities are brought about by the etheric body; they do not result from the earthly forces that work during our evolution, but originate in cosmic forces.

Now, when we trace the evolution of the earth back into the Atlantean or even into the Lemurian epochs, we find that initially impulses and tendencies existed that would have prevented our physical body from developing the physiognomy it now has through the power of the etheric body—that is, the diversities. Instead, if everything had gone a certain way (we shall see directly in what way), the seven-colored etheric body would have brought about diversities in our physical form, but successively, one after the other. Thus, the etheric body would have created one form of human being in the fifth period of Atlantis, a second in the sixth period of Atlantis, a third in the seventh, a fourth in the first post-Atlantean period, a fifth in the second post-Atlantean period, a sixth in the third, and a seventh in the fourth post-Atlantean period, that is, in the Greco-Roman time.

That is what would have happened; various types of human beings would have appeared one after the other. Thus, in the fifth Atlantean period we would have had human beings in whose physical formation one type of etheric body would have predominated. In the sixth Atlantean period, the second of the etheric bodies just described would have been at work, and so on right until the fourth post-Atlantean period. That was the original conception. However, Lucifer and Ahriman opposed this; they did not want it to happen that way. They fought against this harmonious tendency of development in the evolution of humanity, and they managed to change the whole process so that various developments were shifted and displaced. While there should have been basically only one form of human being in the fifth Atlantean period that was to develop gradually into another type, Lucifer and Ahriman preserved the form of the fifth Atlantean period into the sixth, and again that of the sixth Atlantean period into the seventh, and even into the time after the Atlantean flood.

Thus, forms that should have disappeared remained. Instead of racial diversities developing consecutively, older racial forms remained unchanged and newer ones began to evolve at the same time. Instead of the intended consecutive development of races, there was a coexistence of races. That is how it came about that physically different races inhabited the earth and are still there in our time although evolution should really have proceeded as I have described it. Even when we consider only what resulted from the development of the etheric body, we see everywhere that Lucifer and Ahriman play their part in the earthly evolution of humanity.

Now we must ask what the intended consecutive development of humanity up until the Greco-Roman epoch meant in the larger cosmic context. As we know, around the Atlantean time, human souls gradually came down from the planets to which they had ascended. You may remember that I described in my An Outline of Occult Science that the souls had ascended and then came down again and that the life of earthly incarnations, properly speaking, begins with their descent.² Thus, the I of human beings, their individualities, would have gone through the various human forms mentioned above in consecutive periods. In the fifth Atlantean period, the I would have had one human form, in the sixth another, in the seventh again another; in the first post-Atlantean epoch it would have had yet another form, and so on. We would all have lived through these types of humanity, one after the other.

Indeed, it was planned that human beings would thus complete the necessary schooling of human individuality by passing through various etheric formations that had different effects on their physical body. In fact, according to the original plan, there could have been a type of human being on the earth who would have been the result, as it were, of seven successive periods of development, each of which would have contributed to the perfection of that human type. In the fifth post-Atlantean period, then, there would have been one united type of human being spread over the whole face of the earth.

However, Lucifer and Ahriman interfered and thwarted the original design. As a result, the ancient Greeks could only dream of an ideal, superhuman type, which they tried to represent in various ways, for example, in the form of Apollo, Zeus, or Athena. They could not fully encompass this type simply because it did not really exist. But if we have a sense for Greek sculpture, we can feel how the ancient Greeks dreamed of a uniform, perfect, beautiful type of human being that should have developed. This development did not occur because Lucifer and Ahriman preserved older racial forms that had developed, so that there was a coexistence of races rather than a succession.

In the fourth post-Atlantean period, in the Greco-Roman era, human evolution was faced with the fact that what the gods guiding the evolution of the earth had intended for the outer forms on this earth had not been realized because of the luciferic-ahrimanic influence. The spirits of the hierarchy of form had intended that the harmonious working of the various hierarchies of form should really lead to a human type with perfect physical development. As it turned out, the ancient Greeks could only dream of this perfect type and express it in their art.

It is a deeply moving experience to realize in the course of spiritual research why the Greeks created such perfection in their plastic art. They did it because through a soul-spiritual instrument they perceived that Lucifer and Ahriman had disappointed the good divine-spiritual beings, whose plans for humanity were different from the development that actually occurred. What should have developed through the work of these good divine-spiritual beings weighed on the ancient Greeks' minds, and so they wanted to at least represent it even though it did not exist in outer reality. It is great and wonderful and also deeply moving to behold these inner forces of human evolution that appear there in artistic forms, striving to express what could not be achieved in outer reality. Such insights shed new light on Greek art as it was developed so uniquely and unrepeatably at that time.

The Greek era was also the time when humanity faced a crisis because of the luciferic-ahrimanic influence. Lucifer and Ahriman had caused races to live side by side instead of one after the other. At the same time, however, all the forces the spirits of form were pouring into human evolution on the earth were immobilized. Now they could do no more than stimulate and inspire the creative imagination of the Greeks so that it developed as I have described it. The spirits of form had to decide whether the human race should continue to develop so that human beings would never again be united in earthly evolution. For this indeed is what would have happened. If earthly evolution had continued beyond the fourth, the Greco-Roman period, in the same way it was prior to that, then humanity would have become separated into seven groups due to luciferic and ahrimanic forces. These seven groups would have been as different from each other as the various species of animals. Animal species do not understand each other, but regard each other as foreign. Similarly, toward the end of the fourth post-Atlantean period and in the fifth one, in which we live, people would have had to develop more and more the view that there are seven groups of human beings on earth that see each other as completely different species. This view would still have prevailed in our time; in fact, the separation between the seven groups would not yet have reached its culmination or completion, but would still be developing and widening. The term “human being” for all people on earth would have seemed wrong; we would have had seven different terms, one for each of the seven groups.

Therefore, in the fourth post-Atlantean age, in the Greco-Roman period, something had to be done in the universe to forestall the development that threatened to result in the future, at the end of earth evolution, namely, the evolution of seven groups of human beings, each called by a different name, just as each animal species has a different name. These groups would not have regarded each other as belonging to the same species, and at most there would have been handed down to them some copy of the Greek forms, such as the statues of Zeus or Apollo. They would have regarded these statues as something alien to them—something that could never have existed on earth. Precautions had to be taken to prevent such a development. Physical evolution had already gone too far and could not be changed anymore. Therefore, precautions had to be taken for our etheric body; an impulse had to enter our etheric body that would counteract the separating of earthly humanity into seven groups. This impulse that was to counteract the growing fragmentation of humanity and that was to make it possible for the term “human being” to retain—and, in fact, increase—its true meaning over the whole face of the earth was the Mystery of Golgotha, which we can now see in a new light.

The first attempt that had been made with earthly humanity before the luciferic and ahrimanic impulses interfered in evolution was to create unity among human beings everywhere through the forming of the physical body. This attempt by the spirits of form failed because of luciferic-ahrimanic interference. But it could not be allowed to fail altogether; precautions had to be taken to prevent complete failure and to immobilize and offset the work of Lucifer and Ahriman. The physical body could no longer be worked on as was originally intended; therefore, the etheric body had to be worked on. This was done by the divine-spiritual being we have so often spoken of—the Christ Being—taking on human form at the time in human evolution when the possibility to express the archetype of humanity was the greatest.

At what period in human evolution was this? All the forces that counteract the original, identical design of our physical body are at work in us mostly in the first seven years of life, when the physical body is still soft and pliant. They do not allow our physical body to become the same everywhere, but from within the body they immobilize the forces for the original identical design.³ These opposing forces can still go on working in the second seven years until puberty; indeed, they can even continue to work in the third and fourth seven-year periods during the development of the astral body and the sentient soul. However, in the middle of the development of the intellectual or mind soul, which evolved above all in the fourth post-Atlantean or Greco-Roman time, the extra-earthly forces are less and less able to reach us. And in the very midst of this development, that is, in the period between our twenty-eighth and thirty-fifth years, they have least access to us. If we add two years at the beginning of this period and subtract two years at the end, the time in question is that between the thirtieth and the thirty-third year. In the time following those years, extra-earthly forces once more have the greatest influence. The period from the thirtieth to the thirty-third year, however, is the time of the greatest influence of earthly forces on the human being. And if in this period of three years there remained only the degree of diversity that existed in younger years and only what is to appear in later years would be added—in short, if only what works on human beings between the thirtieth and the thirty-third year remained effective, then people would indeed be much more alike.

Christ had to use these three years—very special and unique years—to unite with those earthly forces in human beings that had retained most of the earthly element in the human being. To this end, as we have discussed, the body for Christ was prepared through the two Jesus bodies up to the thirtieth year. Then, from the thirtieth to the thirty-third year, Christ took possession of this body. Where the earth forces were most active and where deformations could have set in, there no further development was possible, and physical death occurred. Thus, the sun-being, Christ, really entered into the earth sphere and united with the whole etheric body of the earth, as I have often explained. He then entered into the earth aura and now continues to work there. This sun-being must work for us in such a way that we realize more and more that in Christ the divine spirit was sent to us who was to counterbalance and redeem from within the separation and diversification in humanity created by Lucifer and Ahriman's opposition to the original impulses.

In outer human nature, the good spiritual beings work together with Lucifer and Ahriman. But what human beings originally, at the beginning of earth evolution, were intended to have on the outside, namely, uniformity and the applicability of the term “human being” everywhere on earth, was now to be brought forth out of the innermost essence of the human being through the Christ-Spirit. It is one of the many meanings of the Mystery of Golgotha that with the Christ-Spirit something was given to the earth that, when rightly understood, makes the name “human being” again applicable to all earthly humanity. The real substance of Christianity, which has already been partially revealed through its teachings, will be explored by those who, in regard to Christ, seek in the spiritual world what Christ is continually revealing in accordance with his words: “I am with you always, to the close of the age.” When what can be conveyed to human beings in the name of Christ from within thus gradually becomes known, then, as a result, what Lucifer and Ahriman did in earthly humanity can more and more be made up for and redeemed.

We may, of course, ask now if there is any meaning in this detour. This is really a childish question, and it is often raised by people who think themselves cleverer than the cosmic wisdom—and indeed there are many who aspire to such superior cleverness. Such people say, “If there are mighty divine beings, could they not have eliminated the luciferic-ahrimanic influence at the beginning of earthly evolution in order to protect their work?” This may be human wisdom, but in St. Paul's sense it is “folly with God.” It is nothing more than mere human wisdom.

In our lectures, we must look at things as we are now doing, and then what has developed through the opposition of Lucifer and Ahriman does not seem absolutely evil to us, but only relatively evil. For let us now consider the other side of the matter. Let us assume the original, divine cosmic plan for the earth had been fulfilled. Imagine that in the regular course of evolution the Greco-Roman era would have arrived, as I have pointed out, and that beautiful, harmonious type of human being the Greeks dreamed of would not only have been created by their sculptors, but would have lived among them and would gradually have spread over the whole earth. All other human forms would gradually have disappeared, and only what lives in the Apollo type, the Zeus type, the Diana type, and the Athena type would have spread over the earth. Since such beings would have recognized each other as belonging to the same species, they would have given themselves the name “human being.” Then the term “human being” would indeed have been applicable, and at the same time there would have been a sense of the equality of all people.

In that case, a human race of Grecian beauty would have spread over the earth, and in our age we would already see humanity approaching more and more this beautiful Grecian type, which would reach its perfection when the earth arrives at its goal in the seventh post-Atlantean epoch, after which it will pass over into other stages of existence. However, human beings would have advanced to this common humanity in unfreedom—that is what we must bear in mind. We would have been compelled to see all human beings everywhere as the same beings. It is only because such an identical form did not develop that all the other things could happen that allow us to see others as different, so that each sees the other as unlike himself and does not love his neighbor as himself. You will probably understand that if human beings had really become outwardly as alike as the original divine-spiritual forces had intended if Lucifer and Ahriman had not interfered, the feeling that one must love one's neighbor as oneself would necessarily have developed. There would not have been any choice; for anything else would have seemed to be nonsense, both in terms of feeling and of perception.

However, this development was not supposed to come from the outside because then it would have made us into beings who love automatically—that is, we would have loved others because they are our own kind, but without knowing the force that urges us to this love. Thus, what would otherwise have come to us in unfreedom was prepared for freedom through Lucifer and Ahriman's opposition. This sanction of the opposition is therefore inherent in the original plan of divine wisdom. Indeed, we may say that in still earlier periods of earthly evolution, the opposition against the harmonious progressive divine-spiritual powers was created precisely so that it could later bring about freedom.

At this point, we must realize that our concepts must change when we leave the sphere of physical observation and ascend to a higher order of perception. Many of you probably know that philosophy speaks of antinomies, and that Kant has even gone so far as to claim that it can be proven with equal conclusiveness that the two statements “the world is infinite in terms of space” and “the world is finite in terms of space” are correct. Similarly, both “the world has had a beginning” and “the world has had no beginning” can be proven conclusively. Why is this? It is because logic does not apply when we come into a sphere that can no longer be comprehended by physical means. We finally have to realize that our physical logic works neither in the realm of philosophy nor anywhere else where we concern ourselves with other than physical forms of existence. We must not make the mistake of looking at the opposition of Lucifer and Ahriman as we would at the antagonism between a good and an evil person on earth. This kind of mistake occurs when we continue to carry over the earthly into the super-earthly realm.

Most people picture Ahriman and Lucifer as evil beings—albeit much more intensely evil than human beings. But this is not true; we must keep in mind that certain earthly feelings we associate with our concepts lose their meaning when we go beyond the earthly realm. Thus we cannot say that there are good gods on the one hand and the evil gods Ahriman and Lucifer on the other. We must not assume that a trial should be held in the universe where a highly qualified cosmic judge would sit on the cosmic judgment seat and sentence Lucifer and Ahriman to be locked up once and for all, so that only the good gods can get to work. True, locking somebody up can at times make sense in earthly life; in the cosmos it would not make any sense because there such ideas and concepts have no meaning. The opposing forces were created by the good gods themselves in an earlier period so that they would be able to bring to bear their full force for the development I have described.

For freedom to enter in so that human beings did not develop an unfree love through their outer shape or form, the luciferic and ahrimanic elements had to be part of our evolution. Only in this way can we arrive from within ourselves at the unity indicated by the term “humanity.” Thus, the gods allowed humanity to be fragmented by the opposing forces, so that later, after their bodily nature had been thus separated, human beings could again be brought into a unity in their spiritual nature through Christ.

This is one of the meanings of the Mystery of Golgotha: the attainment of the unity of humanity from within. Externally human beings are becoming more and more different. The result will be not sameness but difference over the earth, and human beings must exert all the more force from within to attain unity. There will always be setbacks in this process of achieving unity—we can see them coming if we look for them. What was actually intended only for an earlier epoch is preserved into a later epoch, and what was to create differences in consecutive periods coexists. Human beings form different groups, and while they are struggling for unity all over the world in the name of Christ, through the Christ impulse, differences remain as aftereffects and setbacks. Such differences will always exist because human beings will only gradually be able to attain unity. At the same time, different groups will fight each other tooth and nail about everything concerning their outer life. There are setbacks from earlier epochs that run counter to the Christ impulse, rather than in harmony with it.

Indeed, here we see a very profound meaning of this Christ impulse. Based on true knowledge, we can say Christ is our savior who keeps humankind from being fragmented into groups. This is not yet fully understood by all people because the old still exists alongside the new. Today, people hardly understand the community of life in the Christ impulse, and this is connected with the fact that this understanding must proceed from our innermost being. We must realize that the Christ impulse has worked in the earth aura for the last two thousand years, but has not been understood. As we have often emphasized, this Christ impulse can only be fully understood through what spiritual science gives us. It is only when a growing number of people can more and more grasp, think, and feel what actually entered our earthly evolution in the fourth post-Atlantean period that understanding for that event will increase. To expect modern humanity to understand the Christ impulse is really asking too much. After all, just think how unwilling people are to acknowledge that this fourth post-Atlantean period of evolution, the Greco-Roman epoch, is of such paramount, such mighty significance in human evolution. Just think how unwilling people are to recognize any such post-Atlantean age at all with the Greco-Latin epoch as its pivotal point. To accept such truths, people need to take in the ideas of spiritual science. Without them one cannot understand these things at all—that is, one cannot understand the evolution of humanity if one has not taken in these concepts.

We have to understand the significance of the spirits of form, who had intended to develop a homogeneous human race in seven successive stages. This homogeneous human race was fragmented by Lucifer and Ahriman, but the force that wants to spread the one name “human being” over all the earth and unto the end of time—in spite of the outer differences between people—was revived from within by the Christ impulse. One of the chief tasks of the immediate future is to understand that Christ stands between Lucifer and Ahriman and to grasp his significance in relation to them. Therefore, we must always call Lucifer and Ahriman by their true names—we must call a spade a spade, so to speak—and look to the Christ impulse as the one combating them and saving the earth from this one-sided luciferic-ahrimanic impulse. This is what must be presented more and more often.

In our Dornach building we have therefore placed the statue The Representative of Humanity in the most prominent place; it presents the archetype of humanity that is to be recreated by Christ from within, surrounded by the luciferic-ahrimanic elements.⁴ That is the meaning of this central statue in our building. Looking at this central figure, people will realize that this is indeed what the good gods had intended. The human race was fragmented, Lucifer and Ahriman made their appearance, but the Christ impulse triumphs and recreates from within, from within us, what was originally intended for the outside. In the process, our freedom is created. Our building and what will be in it are to place before humanity what must be accomplished in terms of understanding human evolution. What is most needed for humanity in the immediate future is to be revealed in our building; we want people to understand human evolution showing and telling them what is most important for the near future.

Of course, many objections can be raised, and some of them have already been brought to our attention. After seeing the paintings and sculptures in the Goetheanum, some people have said that a true work of art must be understandable immediately to everyone without requiring an explanation. Here, on the other hand, people need theoretical explanations to understand our art works. Well, if people would only think a little! Imagine a Turk, for example, understanding nothing at all except what is contained in the Koran, a Turk who has heard nothing about Christ except that he must fight against Christianity. Suppose you took this Turk to see the Sistine Madonna and showed it to him without any explanations. Naturally, a work of art can only be understood by those who live in the same spiritual stream out of which the work was created. Thus, our ideal figure surrounded by Lucifer and Ahriman will only be understood by those who live in our spiritual stream.

This is true for all works of art in all ages: they are comprehensible only to those who live in the same spiritual stream. Only within that stream are they true works of art. The spiritual orientation must be inherent in them. Those who understand Raphael's Sistine Madonna or, let us say, his Transfiguration must know something of the spiritual stream in which the pictures were created. Similarly, to understand what they have seen in our building, people must have some element belonging to our spiritual stream in their souls and hearts. If they have this element within them, then the work of art must speak for itself, and no labels, identifying names, or other comments will be needed to explain or interpret it.

For example, when people look at one of our glass windows, they see in the bottom part a kind of coffin with a dead man in it; above that, they see an old man, a youth, a young woman, and a child standing on a winding path. If people have taken in our spiritual stream, they will realize that this is the review of life. Immediately after we have passed through the gate of death, we will see the course of our earthly life in reverse. Of course, you have to know this fact to make sense of the picture in the window. But if you know this, then the picture works by virtue of what it contains, just as the Sistine Madonna works upon those who know the Christian history behind it, but it has no such effect on the Turk. By the same token, what is presented in our building cannot work upon those who have not taken in our spiritual stream. These things just have to be seen in the right way.

Today, I wanted above all to explain that Christ was that spirit from the cosmos who, in the course of earthly evolution, brought spiritually what was originally intended for our outer form but could not develop externally, because we would then have become automatons of love and equality. On the physical plane there prevails the fundamental law that everything must operate through antitheses, through polarities. The gods could not simply have sent down Christ at the very beginning of earth evolution, as our naive wisdom might suggest they should have done. For then the antithesis of external fragmentation and inner concentration could never have developed. Humanity, however, must live in this antithesis and polarity. We have the right feelings for Christ only when we see in him the savior, rescuing humanity from dispersion and separateness; only then can Christ fill our own innermost I. Christianity lives wherever people are able to understand this union of all humanity through Christ. In the future, it will not matter much whether what Christ is will still be called by that name. However, a lot will depend on our finding in Christ the spiritual uniter of humanity and accepting that external diversity will increase more and more.

We will also have to accept that there will still be many setbacks for this spiritual understanding of the Christ impulse. What developed at the same time instead of consecutively will for a long time continue to evoke forces that fight against a spiritual understanding of global human equality. There will be many and terrible onslaughts, and, for the most part, their purpose will be to continue the luciferic-ahrimanic war against the Christ impulse. And it will be one of the greatest, most beautiful and significant achievements of our age if we can be among the few who understand this thought of the unifying of all human beings, who understand how remnants of the luciferic-ahrimanic elements strive to bring to the fore what is unique in various groups of human beings so as to exclude all others. It is very difficult to say anything at this time about the final outcome of these matters. As human hearts are now, to speak about that outcome would only be upsetting and bewildering; it may lead to opposition, perhaps even to hatred and abuse rather than to working in accordance with the Christ impulse. However, what can be said about this principle in the Christ impulse, namely, the salvation of humanity out of bodily fragmentation into spiritual unity, must be told, for it must become more and more effective in human evolution.

We have to be able to face calmly and courageously the increasing diversity in human nature because we know that we can carry a word into all these diversities that is not merely a word of speech but one of power. Though there may be groups that fight against each other and though we may even belong to one of them, we know that we can bring something that will express: “It is no longer I who live, but Christ who lives in me” into every group. We know that this “Christ who lives in me” will not lead to the forming of groups; rather, it will bring about the spreading of the glory of the name “human being” over the whole earth.

The understanding of spiritual science brings to life the realization that we can carry the power that comes from the words “It is no longer I who live, but Christ who lives in me” into the groups that are fighting each other—no matter into which group we bring our I. This is one of the practical and moral-ethical aspects of our strivings in spiritual science. With the force of these words we bring something into the group that does not belong exclusively to one or the other group but to all humanity. It is only through this that we can arrive at a true spiritual understanding of Christianity.

It is the hallmark of mighty spiritual paths that they are finally expressed in simple words. Think of the simple words that can express the whole of Christianity, which has permeated the world for nearly two thousand years. But these simple words can only be found on the basis of big, long-term developments. These simple words that express Christianity were not just there all at once; they had to be worked for. We must be aware that we are among those people working to make it possible that someday simple words may be found to express, in a basic, elementary way, the truths we have to spread and develop today. Without such development the simple could never come about. We may not yet be able to put our spiritual science into simple words in any language—words that would condense it on a quarter of a page—so that all striving people would understand it, as was done for Christianity when it originated two thousand years ago. Yet, we can be sure that those simple words will contain something of what I said today, something that will direct our attention to the Greco-Roman age, especially to the Mystery of Golgotha during that time, as well as to the contrast or polarity between Christ and Lucifer-Ahriman.

What can be seen everywhere will be concentrated in a few simple words that can then be handed down to future humanity in the same way as the commandment, “You shall love the Lord your God with all your heart, and with all your soul, and with all your strength, and with all your mind; and your neighbor as yourself.” Just as this commandment expresses something that had to be attained as a result of a long development, so, in the future, the findings of spiritual science will be put into simple words, and then all people will understand them.

This requires our spiritual work, for the simple can only arise in the spiritual evolution of humanity when people have been willing to spend long periods of time learning about the details. You are called upon to help in this development, which will lead to something appearing to people in bright clarity, something we cannot yet express because we do not have the words for it in our languages, yet something spiritual science works toward. When you feel you belong to such a spiritual stream, and feel at home in it, because you see that it is necessary for human evolution, then you have the right understanding of our spiritual movement—you belong to it in such a way that you rightly understand the greatest of its goals based on your increasing understanding of the contrast between Christ and Lucifer-Ahriman. You understand that this contrast is vital and had to exist.

This is what I wanted to bring before your souls today. It is all connected with the question of the meaning of our whole earthly evolution. For when spirits from other planets look down upon the earth and ask what the meaning of this earthly evolution is, they will understand it when they learn about the Mystery of Golgotha. Everything that happens in the course of earthly evolution has its meaning only through the Mystery of Golgotha. The Mystery of Golgotha radiates out into the cosmos and imparts to everything else that radiates out from the earth its meaning, its central meaning.

Today I want to bring up a theme which may seem somewhat remote, but it will be important for the further development of subjects we are studying. We have been able to gather together many essential details for a knowledge of the human being. On the one side, we are gradually discovering its place in the life of the cosmos, and on the other, its place in the social life. But it will be necessary today to consider certain matters which make for a better understanding of the human being and nature.

When the human being is studied by modern scientific thinking, generally only one part of the being is taken into consideration. No account whatever is taken of the fact that in addition to the physical body, there are also higher members. We will leave this aside today and consider something that is more or less recognized in science and has also made its way into the general consciousness.

In studying the human being, only those elements which can be pictured as solid, or solid-fluidic, are regarded as belonging to his organism. It is, of course, acknowledged that the fluid and the airy elements pass into and out of the human being, but these are not in themselves considered to be integral members of the organism. The warmth of the organism which is greater than that of the environment is regarded as a state or condition of the organism, but not as an actual component. We shall see what I mean by saying this. I have already drawn attention to the fact that when we study the rising and falling of the cerebral fluid through the spinal canal, we can observe a regular up-and-down oscillatory movement caused by inhalation and exhalation; when we breathe in, the cerebral fluid is driven upwards and strikes, as it were, against the brain; when we breathe out, the fluid descends. These processes in the purely liquid components of the human organism are not considered to be part and parcel of the organism itself. The general idea is that, as a physical structure, the human organism consists of the more or less solid, or at most, solid-fluid substances found in it. It is generally pictured as a structure built up from these more or less solid substances (Illustration I).

The other elements, the fluid element, as I have shown by the example of the cerebral fluid, and the airy element, are not regarded by anatomy and physiology as belonging to the human organism as such. It is said: Yes, the human being draws in the air which follows certain paths in his body and also has certain definite functions. The air is breathed out again.—Then people speak of the warmth-condition of the body, but in reality they regard the solid element as the only organizing factor and do not realize that in addition to this solid structure they should also see the whole organism as a column of fluid (blue), as being permeated with air (red) and as having a definite degree of warmth (yellow).(Illustration II) More exact study shows that just as the solid or solid-fluid constituents are an integral component of the organism, so the fluid should not be thought of as so much uniform fluid, but differentiated and organized—though the process here is a more fluctuating one—and having its own particular significance.

In addition to the solid components, therefore, we must bear in mind the 'fluid' and also the 'air'. For the air that is within us, in regard to its organization and its differentiations, is an organism in the same sense as the solid organism, only it is gaseous, airy, and in motion. And finally, the warmth in us is not a uniform warmth extending over the whole human being, but is also delicately organized. As soon, however, as we begin to speak of the fluid organism which fills the same space that is occupied by the solid organism, we realize immediately that we cannot speak of this fluid organism in the earthly human without speaking of the etheric body which permeates this fluid organism and fills it with forces. The physical organism exists for itself, as it were; it is the physical body; in so far as we consider it in its entirety, we regard it, to begin with, as a solid organism. (blue) This is the physical body.

We then come to consider the fluid organism, which cannot, of course, be investigated in the same way as the solid organism, by dissection, but which must be conceived as an inwardly mobile, fluidic organism. It cannot be studied unless we think of it as permeated by the etheric body.

Third, there is the airy organism which again cannot be studied unless we think of it as permeated with forces by the astral body.

Fourth, there is the warmth organism with all its inner differentiation. It is permeated by the forces of the Ego.—That is how the human as earthly being today is constituted.

Physical organism: Physical body

Regarded in a different way

1) Solid organism	Physical body
2) Fluid organism	Etheric body
3) Airy organism	Astral body
4) Warmth organism	Ego

Let us think, for example, of the blood. Inasmuch as it is mainly fluid, inasmuch as this blood belongs to the fluid organism, we find in the blood the etheric body which permeates it with its forces. But in the blood there is also present what is generally called the warmth-condition. But that ‘organism’ is by no means identical with the organism of the fluid blood as such. If we were to investigate this—it can also be done with physical methods of investigation—we would find in registering the warmth in the different parts of the human organism that the warmth cannot be identified with the fluid or with any other organism.

As soon as we reflect in this way we find that it is impossible for our thought to come to a standstill within the limits of the human organism itself. We can remain within these limits only if we are thinking merely of the solid organism which is shut off by the skin from the outside. Even this, however, is only apparently so. The solid structure is generally regarded as if it were a firm, self-enclosed block; but it is also inwardly differentiated and is related in manifold ways to the solid earth as a whole. This is obvious from the fact that the different solid substances have, for example, different weights; this alone shows that the solids within the human organism are differentiated, have different specific weights. In regard to the physical organism, therefore, the human being is related to the earth as a whole. Nevertheless it is possible, according at least to external evidence, to place spatial limits around the physical organism.

It is different when we come to the second, the fluid organism that is permeated by the etheric body. This fluid organism cannot be strictly demarcated from the environment. Whatever is fluid in any area of space adjoins the fluid element in the environment. Although the fluid element as such is present in the world outside us in a rarefied state, we cannot make such a definite demarcation between the fluid element within and the fluid element outside the human organism, as in the case of the solid organism. The boundary between the inner fluid organism and the fluid element in the external world must therefore be left indefinite.

This is even more emphatically the case when we come to consider the airy organism which is permeated by the forces of the astral body. The air within us at a certain moment was outside us a moment before, and it will soon be outside again. We are drawing in and giving out the airy element all the time. We can really think of the air which surrounds our earth, and say: it penetrates into our organism and withdraws again; but by penetrating into our organism it becomes an integral part of it. In our airy organism we actually have something that constantly builds itself up out of the whole atmosphere and then withdraws again into the atmosphere. Whenever we breathe in, something is built up within us, or, at the very least, each indrawn breath causes a change, a modification, in an upbuilding process within us. Similarly, a destructive, partially destructive, process takes place whenever we breathe out. Our airy organism undergoes a certain change with every indrawn breath; it is not exactly newly born, but it undergoes a change, both when we breathe in and when we breathe out. When we breathe out, the airy organism does not, of course, die; it merely undergoes a change; but there is constant interaction between the airy organism within us and the air outside. The usual trivial conceptions of the human organism can only be due to the failure to realize that there is but a slight degree of difference between the airy organism and the solid organism.

And now we come to the warmth organism. It is of course quite in keeping with materialistic-mechanistic thought to study only the solid organism and to ignore the fluid organism, the airy organism, and the warmth organism. But no real knowledge of the human organism can be acquired unless we are willing to acknowledge this membering into a warmth organism, an airy organism, a fluid organism, and an earth organism (solid).

The warmth organism is paramountly the field of the Ego. The Ego itself is that spirit-organization which imbues with its own forces the warmth that is within us, and governs and gives it configuration, not only externally but also inwardly. We cannot understand the life and activity of the soul unless we remember that the Ego works directly upon the warmth. It is primarily the Ego in man which activates the will, generates impulses of will.—How does the Ego generate impulses of will? From a different point of view we have spoken of how impulses of will are connected with the earthly sphere, in contrast to the impulses of thought and ideation which are connected with forces outside and beyond the earthly sphere. But how does the Ego, which holds together the impulses of will, send these impulses into the organism? This is achieved through the fact that the will works primarily in the warmth organism. An impulse of will proceeding from the Ego works upon the warmth organism. Under present earthly conditions it is not possible for what I shall now describe to you to be there as a concrete reality. Nevertheless it can be envisaged if we disregard the physical organization within the space bounded by the human skin, if we disregard also the fluid organism, and the airy organism. The space then remains filled with nothing but warmth which is, of course, in communication with the warmth outside. But what is active in this warmth, what stirs it into movement, makes it into an organism—is the Ego.

The astral body contains the forces of feeling; it brings these forces of feeling into physical operation in the human airy organism.

The constitution of the human as earthly being is such that, by way of the warmth organism, the Ego gives rise to what comes to expression when we act in the world as a being of will. The feelings experienced in the astral body and coming to expression in the earthly organization manifest in the airy organism. And when we come to the etheric body, we find within it the conceptual process, insofar as this has a pictorial character—more strongly pictorial than we are consciously aware of to begin with, for the physical body still intrudes and tones down the pictures into mental concepts. This process works upon the fluid organism.

This shows us that by taking these different organisms into account we come nearer to the life of soul. Materialistic observation, which stops short at the solid structure and insists that in the very nature of things water cannot become an organism, is bound to confront the life of soul with complete lack of understanding; for it is precisely in these other organisms that the life of soul comes to immediate expression. The solid organism itself is, in reality, only that which provides support for the other organisms. The solid organism stands there as a supporting structure composed of bones, muscles, and so forth. Into this supporting structure is membered the fluid organism with its own inner differentiation and configuration; in this fluid organism vibrates the etheric body, and within this fluid organism the thoughts are produced.

How are the thoughts produced? Through the fact that within the fluid organism something asserts itself in a particular metamorphosis—namely, what we know in the external world as tone. Tone is, in reality, something that leads the ordinary mode of observation very much astray. As earthly human beings we perceive the tone as being borne to us by the air. But in point of fact the air is only the transmitter of the tone, which actually weaves in the air. And anyone who assumes that the tone in its essence is merely a matter of air-vibrations is like a person who says: Man has only his physical organism, and there is no soul in it. If the air-vibrations are thought to constitute the essence of the tone, whereas they are in truth merely its external expression, this is the same as seeing only the physical organism with no soul in it. The tone which lives in the air is essentially an etheric reality. And the tone we hear by way of the air arises through the fact that the air is permeated by the Tone Ether (see diagram III) which is the same as the Chemical Ether. In permeating the air, this Chemical Ether imparts what lives within it to the air, and we become aware of what we call the tone.

This Tone Ether or Chemical Ether is essentially active in our fluid organism. We can therefore make the following distinction: In our fluid organism lives our own etheric body; but in addition there penetrates into it (the fluid organism) from every direction the Tone Ether which underlies the tone. Please distinguish carefully here. We have within us our etheric body; it works and is active by giving rise to thoughts in our fluid organism. But what may be called the Chemical Ether continually streams in and out of our fluid organism. Thus we have an etheric organism complete in itself, consisting of Chemical Ether, Warmth Ether, Light Ether, Life Ether, and in addition we find in it, in a very special sense, the Chemical Ether which streams in and out by way of the fluid organism.

The astral body which comes to expression in feeling operates through the air organism. But—still another kind of Ether by which the air is permeated is connected especially with the air organism. It is the Light Ether. Earlier conceptions of the world always emphasized this affinity of the outspreading physical air with the Light Ether which permeates it. This Light Ether that is borne, as it were, by the air and is related to the air even more intimately than tone, also penetrates into our air organism and it underlies what there passes into and out of it. Thus we have our astral body which is the bearer of feeling, which is especially active in the air organism, and is in constant contact there with the Light Ether.

And now we come to the Ego. This human Ego, which by way of the will is active in the warmth organism, is again connected with the outer warmth, with the instreaming and outstreaming Warmth Ether.

Thus we obtain the following relations:

Ego—Will—Warmth organism—Warmth Ether.
Astral body—Feeling—Air Organism—Light Ether.
Etheric body—Thinking—Fluid Organism—Chemical Ether.

Now consider the following. The etheric body remains in us also during sleep, from the moment of falling asleep to the moment of waking; therefore the interworking of the Chemical Ether and the etheric body continues within our being, via the fluid organism, also while we are asleep. It is different in the case of the astral body and feeling. From the moment of falling asleep to the moment of waking, the astral body is outside the human organism; then the astral body and feeling do not then work upon the air organism, but the air organism—connected as it is with the whole surrounding world—is sustained from outside during sleep. And the human being, with astral body and feeling, goes out of the body and passes into a world with which it is related primarily through the Light Ether. While asleep we live directly in an element that is transmitted to our astral body by the air organism during waking life. We can speak in a similar way of the Ego and the warmth organism.

It is obvious from this that an understanding of our connection with the surrounding universe is possible only as the result of thorough study of these members of being, of which ordinary, mechanistic thinking takes no account at all. But everything in us interpenetrates, and because the Ego is in the warmth organism it also permeates the air organism, the fluid organism, and the solid organism; it permeates them with the warmth which is all-pervading. Thus the warmth organism lives within the air organism; the warmth organism, permeated as it is with the forces of the Ego, also works in the fluid organism.

This indicates how, for example, we should look for the way in which the Ego works in the circulating blood. It works in the circulating blood by way of the warmth organism—works as the spiritual entity which, as it were, sends down the will out of the warmth, via the air, into the fluid organism. Thus everything in the human organism works upon everything else. But we will get nowhere if we have only general abstract ideas of this interpenetration; we will reach a result only if we can evolve a concrete idea of our constitution and of how everything that is around us participates in our make-up.

The condition of sleep, too, can be understood only if we go much more closely into these matters. During sleep it is only the physical body and the etheric body that remain as they are during the waking state; the Ego and the astral body are outside. But in the sleeping human being the forces that are within the physical and etheric bodies are then also active on the airy organism and the warmth organism as well.

When we turn to consider waking life, from what has been said we shall understand the connection of the Ego with the astral body and with the whole organism. During sleep, when the Ego and the astral body are outside, the four elements are nevertheless within the human organism: the solid supporting structure, the fluid organism, but also the air organism in which the astral body otherwise works, and the warmth organism in which the Ego otherwise works. These elements are within the human organism and they work in just as regularly organized a way during sleep as during the waking state, when the Ego and the astral body are active within them.

During the sleeping state we have within us, instead of the Ego—which is now outside—the spirit which permeates the cosmos and which in waking life we have driven out through our Ego which is part of that spirit. During sleep our warmth-body is permeated by cosmic spirituality, our air organism by what may be called cosmic astrality (or world-soul), which we also drive out while we are awake.

Waking life and sleeping life may therefore also be studied from this point of view. When we are asleep our warmth organism is permeated by the cosmic spirituality which on waking we drive out through our Ego, for in waking life it is the Ego that brings about in the warmth organism what is otherwise brought about by the cosmic spirituality. It is the same with the cosmic astrality; we drive it out when we wake up and readmit it into our organism when we fall asleep. Thus we can say: By leaving our body during sleep, we allow the cosmic spirit to draw into our warmth organism, and the world-soul, or the cosmic astrality, into our airy organism.

If we study the human being without preconceived ideas, we acquire understanding not only of our relation to the surrounding physical world, but also of our relation to the cosmic spirituality and to the cosmic astrality.

This is one aspect of the subject. We can now consider it also from the aspect of knowledge, of cognition, and you will see how the two aspects tally with each other. It is customary to call 'knowledge' only what one experiences through perception and the intellectual elaboration of perceptions from the moment of waking to that of falling asleep. But thereby we come to know our physical environment only. If we adhere to the principles of spiritual-scientific thinking and do not indulge in fantasy, we shall not, of course, regard the pictures of dream-life as immediate realities in themselves, neither shall we seek in dreams for knowledge as we seek it in waking mental activity and perception. Nevertheless at a certain lower level, dreaming is a form of knowledge. It is a particular form of physical self-knowledge. Roughly, it can be obvious that a man has been 'dreaming' inner conditions when, let us say, he wakes up with the dream of having endured the heat of an intensely hot stove and then, on waking, finds that he is feverish or is suffering from some kind of inflammatory condition. In other ways too, dreams assume definite configuration. Another person may dream of coiling snakes when something is out of order in the intestines; or she may dream of caves into which she is obliged to creep, and then wakes up with a headache, and so on. Obscurely and dimly, dreams point to our inner organic life, and we can certainly speak of a kind of lower knowledge as being present in dreams. There is merely an enhancement of this when the dreams of particularly sensitive people present very exact reflections of the organism.

It is generally believed that deep, dreamless sleep contributes nothing at all in the way of knowledge, that dreamless sleep is quite worthless as far as knowledge is concerned. But this is not the case. Dreamless sleep has its definite task to perform for knowledge—knowledge that has an individualpersonal bearing. If we did not sleep, if our life were not continually interrupted by periods of sleep, we would be incapable of reaching a clear concept of the ‘I’, the Ego; we could have no clear realization of our identity. We would experience nothing except the world outside and lose ourselves entirely in it. Insufficient attention is paid to this, because people are not in the habit of thinking in a really unprejudiced way about what is experienced in the life of soul and in the bodily life.

We look back over our life, at the series of images of our experiences to the point to which memory extends. But this whole stream of remembrances is interrupted every night by sleep. In the backward survey of our life the intervals of sleep are ignored. It does not occur to us that the stream of memories is ever and again interrupted by periods of sleep. The fact that it is so interrupted means that, without being conscious of it, we look into a void, a nothingness, as well as into a sphere that is filled with content.

If here we have a white sphere with a black area in the middle, we see the white and in the middle the black, which, compared with the white, is a void, a nothingness. (This is not absolutely accurate but we need not think of that at the moment.) We see the black area, we see that in the white sphere something has been left free, but this is equally a positive impression although not identical with the impressions of the white sphere. The black area also gives a positive impression. In the same way the experience is a positive one when we are looking back over our life and nothing flows into this retrospective survey from the periods of sleep. What we slept through is actually included in the retrospective survey, although we are not directly conscious of it because consciousness is focused entirely on the pictures left by waking life. But this consciousness is inwardly strengthened through the fact that in the field of retrospective vision there are also empty places; this constitutes the source of our consciousness insofar as it is inward consciousness. We would lose ourselves entirely in the external world if we were always awake, if this waking state were not continually interrupted by sleep. But whereas dream-filled sleep mirrors back to us in chaotic pictures certain fragments of our inner, organic conditions, dreamless sleep imparts to us the consciousness of our organization as human—again, therefore, knowledge. Through waking consciousness we perceive the external world. Through dreams we perceive—but dimly and without firm definition—fragments of our inner, organic conditions. Through dreamless sleep we come to know our organization in its totality, although dimly and obscurely. Thus we have already considered three stages of knowledge: dreamless sleep, dream-filled sleep, the waking state.

Then we come to the three higher forms of knowledge: Imagination, Inspiration, Intuition. These are the stages which lie above ordinary waking consciousness and as states of consciousness become ever clearer, yielding more and more data of knowledge; whereas below the ordinary consciousness we come to those chaotic fragments of knowledge which are nevertheless necessary for ordinary forms of experience.

This is how we must think of the field of consciousness. We should not speak of having only the ordinary waking consciousness any more than we should speak of having only the familiar solid organism. We must speak to the effect that the solid organism is something that exists within a clearly demarcated space, so that if we think in an entirely materialistic way, we shall take this to be the human organism itself. We must remember that ordinary consciousness is actually present, that its ideas and mental pictures come to us in definite outlines. But we should neither think that we have the solid body only, nor that we have this day-consciousness only. For the solid body is permeated by the fluid body which has an inwardly fluctuating organization, and again the clear day-consciousness is permeated by the dream-consciousness, yielding pictures which have no sharp outlines but fluctuating outlines, for consciousness here itself becomes 'fluid' in a certain sense. And as well as the fluid organism we have the air organism, which during the sleeping state is sustained by something that is not ourselves, and hence is not entirely, but only partially and transiently, connected with our own life of soul—namely in waking life only; nevertheless we have it within us as an actual organism.

We have also a third state of consciousness, the dark consciousness of dreamless sleep, in which ideas and thought-pictures become not only hazy but dulled to the degree of inner darkness; in dreamless sleep we cease altogether to experience consciousness itself, just as under certain circumstances, while we are asleep, we cease to experience the airy body.

So you see, no matter whether we study the human being from the inner or the outer aspect, we reach an ever fuller and wider conception of its nature, and constitution. Passing from the solid body to the fluid body to the air body to the warmth body, we come to the life of soul. Passing from the clear day-consciousness to the dream-consciousness, we come to the body. And we come to the body in a still deeper sense through the knowledge of being within it through dreamless sleep. When we carry the waking consciousness right down into the consciousness of dreamless sleep and observe the human being in the members of its consciousness, we come to the bodily constitution. When we consider the bodily constitution itself, from its solid state up to its warmth-state, we pass out of the bodily constitution.

This shows you how necessary it is not simply to accept what is presented to biased, external observation. There, on the one side, is the solid body, to which materialistic-mechanistic thought is anchored; and on the other side there is the life of soul which to modern consciousness appears endowed with content only in the form of experiences belonging to the clear day-consciousness. Thought based on external observation alone does not go downwards from this state of consciousness. (See diagram I: Ego), for if it did it would come to the body. It does not go downwards from the spiritual body (warmth-body), for if it did it would be led to the solid body. This kind of thinking studies the solid body without either the fluid body, the air body or the warmth body, and the day-consciousness without that which in reality reflects the inner bodily nature—without the dream-consciousness and the consciousness of dreamless sleep.

On the basis of academic psychology, the question is asked: How does the soul and spirit live in the physical body?—In reality we have the solid body, the fluid body, the air body and the warmth body. (Diagram V.) By way of the warmth body the Ego unfolds the clear day-consciousness. But coming downwards we have the dream-consciousness, and still farther downwards the consciousness of dreamless sleep. Descending even farther (diagram V, horizontal shading), we come—as you know from the book Occult Science—to still another state of consciousness which we need not consider now. If we ask how what is here on the right (diagram V) is related to what is on the left, we shall find that they harmonize, for here (arrow at left side), ascending from below upwards, we come to the soul-realm; and here (arrow at right side) we come to the bodily constitution: the right and the left harmonize.

The externalized thinking of today takes account only of the solid body, and again only of this state of consciousness (Ego). The Ego hovers in the clouds and the solid body stands on the ground—and no relation is found between the two. If you read the literature of modern psychology you will find the most incredible hypotheses of how the soul works upon the body. But this is all due to the fact that only one part of the warmth body is taken into account, and then something that is entirely separated from it—one part of the soul. (Diagram VI, oblique shading.)

That Spiritual Science aims everywhere for wholeness of view, that it must build the bridge between the bodily constitution on the one side and the life of soul on the other, that it draws attention to states of being where the soul element becomes a bodily element, the bodily element a soul element—all this riles our contemporaries, who insist upon not going beyond what presents itself to external, prejudiced contemplation.

I tried yesterday to give certain indications about the constitution of the human being, and at the end it was possible to show that a really penetrating study of human nature is able to build a bridge between the external constitution, and what it unfolds through self-consciousness, and the inner life. As a rule no such bridge is built, or only very inadequately built, particularly in the science current today. It became clear to us that in order to build this bridge we must know how the human constitution is to be regarded. We saw that the solid or solid-fluid organism—which is the sole object of study today and is alone recognized by modern science as organic in the real sense—we saw that this must be regarded as only one of the organisms in the human constitution; that the existence of a fluid organism, an airy organism, and a warmth organism must also be recognized. Naturally, up to the warmth organism itself, everything is to be conceived as physical body. But it is paramountly the etheric body that takes hold of the fluid body, of everything that is fluid in the human organism; in everything airy, the astral body is paramountly active, and in the warmth organism, the Ego. By recognizing this we can, as it were, remain in the physical but at the same time reach up to the spiritual.

We also studied consciousness at its different levels. As I said yesterday, it is usual to take account only of the consciousness known to us in waking life from the moment of waking to the moment of falling asleep. We perceive the objects around us and reason about these perceptions with our intellect; we also have feelings in connection with these perceptions, and we have our will impulses. But we experience this whole nexus of consciousness as something which, in its qualities, differs completely from the physical which alone is taken account of by ordinary science.

It is not possible, without further ado, to build a bridge from these imponderable, incorporeal experiences in the domain of consciousness to the other objects of perception studied in physiology or physical anatomy. In regard to consciousness too, we know from ordinary life that in addition to the waking consciousness, there is dream consciousness, and we heard yesterday that dreams are essentially pictures or symbols of inner organic processes. Something is going on within us all the time, and in our dreams it comes to expression in pictures. I said that we may dream of coiling snakes when we have some intestinal disorder, or we may dream of an excessively hot stove and wake up with palpitations of the heart. The overheated stove symbolized irregular beating of the heart, the snakes symbolized the intestines, and so forth. Dreams point us to our organism. The consciousness of dreamless sleep is, as it were, an experience of nullity, of the void. But I explained that this experience of the void is necessary in order that we feel ourselves connected with our bodily nature. As an Ego we would feel no connection with our body if we did not leave it during sleep and seek for it again on waking. It is through the deprivation undergone between falling asleep and waking that we are able to feel ourselves united with the body. So from the ordinary consciousness which has really nothing to do with our own essential being beyond the fact that it enables us to have perceptions and ideas, we are led to the dream-consciousness which has to do with actual bodily processes. We are therefore led to the body. We are led to the body even more strongly when we pass into the consciousness of dreamless sleep.

Thus we can say: On the one hand our conception of the life of soul is such that it leads us to the body. And our conception of the bodily constitution, comprising as it does the fluid organism, the airy organism, the warmth organism and thus becoming by degrees more rarefied, leads us to the realm of soul. It is absolutely necessary to take these things into consideration if we are to reach a view of the world that can really satisfy us.

The great question with which we have been concerning ourselves for weeks, the cardinal question in one's conception of the world, is this: How is the moral world order connected with the physical world order? As has been said so often, the prevailing world view—which relies entirely upon natural science for knowledge of the outer physical world—can only resort to earlier religious beliefs when it is a matter of any comprehensive understanding of the life of soul. In modern psychology there really is no longer any such understanding—this world view is unable to build a bridge. There, on the one side, is the physical world; according to contemporary views this is a conglomeration from a primeval nebula and everything will eventually become a kind of slag heap in the universe. This is the picture of the evolutionary process presented to us by the science of today, and it is the one and only picture in which a really honest modern scientist can find reality.

Within this picture there is no room for a moral world order. It is there on its own. One receives the moral impulses into oneself as impulses of soul. But if the assertions of natural science are true, that first everything was astir with life, then finally the human being emerged out of the primeval nebula and only then the moral ideals well up within. And when, as is alleged, the world becomes a slag heap, this will also be the graveyard of all moral ideals. They will have vanished.—No bridge can possibly be built, and what is worse, modern science cannot, without being inconsistent, admit the existence of morality in the world order. Only if modern science is inconsistent can it accept the moral world order as valid. It cannot do so if it is consistent. The root of all this is that the only kind of anatomy in existence is concerned exclusively with the solid organism and no account is taken of the fact that the human being also has a fluid organism, an airy organism, and a warmth organism. If you picture to yourselves that as well as the solid organism with its configuration into bones, muscles, nerve fibers and so forth, you also have a fluid organism and an airy organism—though these are of course fluctuating and inwardly mobile—and a warmth organism, if you picture this you will more easily understand what I shall now have to say on the basis of spiritual-scientific observation.

Think of a person whose soul is fired with enthusiasm for a high moral ideal, for the ideal of generosity, of freedom, of goodness, of love, or whatever it may be. That person may also feel enthusiasm for examples of the practical expression of these ideals. But nobody can conceive that the enthusiasm which fires the soul penetrates into the bones and muscles as described by modern physiology or anatomy. If you really take counsel with yourself, however, you will find it quite possible to conceive that when one has enthusiasm for a high moral ideal, this enthusiasm has an effect upon the warmth organism.—There, you see, we have come from the realm of soul into the physical!

Taking this as an example, we may say: Moral ideals come to expression in an enhancement of warmth in the warmth organism. Not only is one warmed in soul through what is experienced in the way of moral ideals, but one becomes organically warmer as well—though this is not so easy to prove with physical instruments. Moral ideals, then, have a stimulating, invigorating effect upon the warmth organism. You must think of this as a real and concrete happening: enthusiasm for a moral ideal—stimulation of the warmth organism. There is more vigorous activity in the warmth organism when the soul is fired by a moral ideal.

Neither does this remain without effect upon the rest of one's constitution. As well as the warmth organism there is also the air organism. We inhale and exhale the air; but during the inbreathing and outbreathing process the air is within us. It is of course inwardly in movement, in fluctuation, but equally with the warmth organism it is an actual air organism in us. Warmth, quickened by a moral ideal, works in turn upon the air organism, because warmth permeates the whole human organism, permeates every part of it. The effect upon the air organism is not that of warming only, for when the warmth, stimulated in the warmth organism, works upon the air organism, it imparts to it something that I can only call a source of light. Sources of light, as it were, are imparted to the air organism, so that moral ideals which have a stimulating effect upon the warmth organism produce sources of light in the air organism. To external perception and for ordinary consciousness these sources of light are not in themselves luminous, but they manifest in the astral body. To begin with, they are curbed—if I may use this expression—through the air that is within us. They are, so to speak, still dark light, in the sense that the seed of a plant is not yet the developed plant. Nevertheless we have a source of light within us through the fact that we can be fired with enthusiasm for moral ideals, for moral impulses.

We also have within us the fluid organism. Warmth, stimulated in the warmth organism by moral ideals, produces in the air organism what may be called a source of light which remains, to begin with, curbed and hidden. Within the fluid organism—because everything in the human constitution interpenetrates—a process takes place which underlies the outer tone conveyed in the air. I said that the air is only the body of the tone, and anyone who regards the essential reality of tone as a matter of vibrations of the air, speaks of tones just as he would speak of a person as having nothing except the outwardly visible physical body. The air with its vibrating waves is nothing but the outer body of the tone. In the human being this tone, this spiritual tone, is not produced in the air organism through the moral ideal, but in the fluid organism. The sources of tone, therefore, arise in the fluid organism.

We regard the solid organism as the densest of all, as the one that supports and bears all the others. Within it, too, something is produced as in the case of the other organisms. In the solid organism there is produced what we call a seed of life—but it is an etheric, not a physical, seed of life such as issues from the female organism at a birth. This etheric seed which lies in the deepest levels of subconsciousness is actually the primal source of tone and, in a certain sense, even the source of light. This is entirely hidden from ordinary consciousness, but it is there within us.

Think of all the experiences in your life that came from aspiration for moral ideas—be it that they attracted you merely as ideas, or that you saw them coming to expression in others, or that you felt inwardly satisfied by having put such impulses into practice, by letting your deeds be fired by moral ideals—all this goes down into the air organism as a source of light, into the fluid organism as a source of tone, into the solid organism as a source of life.

These processes are withdrawn from the field of our normal consciousness but they are active nevertheless. They become free when we lay aside our physical body at death. What is thus produced in us through moral ideals, or through the loftiest and purest ideas, does not bear immediate fruit. For during the life between birth and death, moral ideas as such become fruitful only insofar as we remain in the life of ideas, and insofar as we feel a certain satisfaction in moral deeds performed. But this is merely a matter of remembrance, and has nothing to do with what actually penetrates down into the different organisms as the result of enthusiasm for moral ideals.

So we see that our whole constitution, beginning with the warmth organism, is, as a matter of fact, permeated by moral ideals. And when at death the etheric body, the astral body, and the Ego emerge from the physical body, these higher members of our human nature are filled with all the impressions we have had. Our Ego was living in the warmth organism when it was quickened by moral ideas. We were living in our air organism, into which were implanted sources of light which now, after death, go forth into the cosmos together with us. In our fluid organism, tone was kindled which now becomes part of the Music of the Spheres, resounding from us into the cosmos. And we bring life with us when we pass out into the cosmos through the portal of death.

You will now begin to have an inkling of what the life that permeates the universe really is. Where are the sources of life? They lie in that which quickens those moral ideals which fire us with enthusiasm. We come to the point of saying to ourselves that if today we allow ourselves to be inspired by moral ideals, these will carry forth life, tone and light into the universe and will become world-creative. We carry out into the universe world-creative power, and the source of this power is the moral element.

So when we study the whole human being we find a bridge between moral ideals and what works as life-giving force in the physical world, even in the chemical sense. For tone works in the chemical sense by assembling substances and dispersing them again. Light in the world has its source in the moral stimuli, in the warmth organisms of human beings. Thus we look into the future—new worlds take shape. And as in the case of the plant we must go back to the seed, so in the case of these future worlds that will come into being, we must go back to the seeds which lie in us as moral ideals.

And now think of theoretical ideas in contrast to moral ideals. In the case of theoretical ideas everything is different, no matter how significant these ideas may be, for theoretical ideas produce the very opposite effect to that of moral ideals They cool down the warmth organism—that is the difference.

Moral ideas, or ideas of a moral-religious character, which fire us with enthusiasm and become impulses for deeds, work as world-creative powers. Theoretical ideas and speculations have a cooling, subduing effect upon the warmth organism. Because this is so, they also have a paralyzing effect upon the air organism and upon the source of light within it; they have a deadening effect upon tone, and an extinguishing effect upon life. In our theoretical ideas the creations of the pre-existing world come to their end. When we formulate theoretical ideas a universe dies in them. Thus do we bear within us the death of a universe and the dawn of a universe.

Here we come to the point where he who is initiated into the secrets of the universe cannot speak, as so many speak today, of the conservation of energy or the conservation of matter. It is simply not true that matter is conserved forever.[1] Matter dies to the point of nullity, to a zero-point. In our own organism, energy dies to the point of nullity through the fact that we formulate theoretical thoughts. But if we did not do so, if the universe did not continually die in us, we should not be human in the true sense. Because the universe dies in us, we are endowed with self-consciousness and are able to think about the universe. But these thoughts are the corpse of the universe. We become conscious of the universe as a corpse only, and it is this that makes us human.

A past world dies within us, down to its very matter and energy. It is only because a new universe at once begins to dawn that we do not notice this dying of matter and its immediate rebirth. Through our theoretical thinking, matter—substantiality—is brought to its end; through our pictorial thinking, matter and cosmic energy are imbued with new life. Thus what goes on inside the boundary of the human skin is connected with the dying and birthing of worlds. This is how the moral order and the natural order are connected. The natural world dies away in man; in the realm of the moral a new natural world comes to birth.

Because of unwillingness to consider these things, the ideas of the imperishability of matter and energy were invented. If energy were imperishable and matter were imperishable there would be no moral world-order. But today it is desired to keep this truth concealed and modern thought has every reason to do so, because otherwise it would have to eliminate the moral world-order—which in actual fact it does by speaking of the law of the conservation of matter and energy. If matter is conserved, or energy is conserved, the moral world-order is nothing but an illusion, a mirage. We can understand the course of the world's development only if we grasp how out of this 'illusory' moral world order—for so it is when it is grasped in thoughts—new worlds come into being.

Nothing of this can be grasped if we study only the solid component of man's constitution. To understand it we must pass from the solid organism through the fluid and airy organisms to the warmth organism. Our connection with the universe can be understood only if the physical is traced upwards to that rarefied state wherein the soul can be directly active in the rarefied physical element, as for example in warmth. Then it is possible to find the connection between body and soul.

However many treatises on psychology may be written—if they are based upon what is studied today in anatomy and physiology it will not be possible to find any transition to the life of soul from this solid, or solid-fluid bodily constitution. The life of soul will not be revealed as such. But if the bodily substance is traced back to warmth, a bridge can be built from what exists in the body as warmth to what works from out of the soul into the warmth in the human organism.

There is warmth both outside and inside the human organism. As we have heard, in the human constitution warmth is an organism; the soul, the soul and spirit, takes hold of this warmth organism and by way of the warmth all that becomes active which we inwardly experience as the moral. By the ‘moral’ I do not of course mean what Philistines mean by it, but I mean the moral in its totality, that is to say, all those impulses that come to us, for example when we contemplate the majesty of the universe, when we say to ourselves: We are born out of the cosmos and we are responsible for what goes on in the world.—I mean the impulses that come to us when the knowledge yielded by Spiritual Science inspires us to work for the sake of the future. When we regard Spiritual Science itself as a source of the moral, this, more than anything else, can fill us with enthusiasm for the moral, and this enthusiasm, born of spiritual-scientific knowledge, becomes in itself a source of morality in the higher sense. But what is generally called 'moral' represents no more than a subordinate sphere of the moral in the universal sense.

All the ideas we evolve about the external world, about Nature in her finished array, are theoretical ideas. No matter with what exactitude we envisage a machine in terms of mathematics and the principles of mechanics, or the universe in the sense of the Copernican system—this is nothing but theoretical thinking, and the ideas thus formulated constitute a force of death within us; a corpse of the universe is within us in the form of thoughts, of ideas.

These matters create deeper and deeper insight into the universe in its totality. There are not two orders, a natural order and a moral order in juxtaposition, but the two are one. This is a truth that must be realized by us today. Otherwise we must ever and again be asking ourselves: How can any moral impulses take effect in a world in which a natural order alone prevails?—This indeed was the terrible problem that weighed upon thinkers in the nineteenth century and early twentieth century: How is it possible to conceive of any transition from the natural world into the moral world, from the moral world into the natural world?—The fact is that nothing can help to solve this perplexing, fateful problem except spiritual-scientific insight into Nature on the one side and into the Spirit on the other.

With the premises yielded by this knowledge we shall also be able to get to the root of something that is presented as a branch of science today and has already penetrated into the general consciousness of mankind. Our worldview today is based upon Copernicanism. Until the year 1827 the Copernican conception of the universe which was elaborated by Kepler and then diluted into theory by Newton, was tabooed by the Roman Catholic Church. No orthodox Catholic was allowed to believe it. Since that year the prohibition has been lifted and the Copernican view of the universe has taken root so strongly in the general consciousness that anyone who does not base his own worldview upon it is regarded as a fool.

What is this Copernican picture of the universe?—It is in reality a picture built up purely on the basis of mathematical principles, mathematical-mechanical principles. The rudiments of it began, very gradually, to be unfolded in Greece[2] where, however, echoes of earlier thought—for example in the Ptolemaic view of the universe—still persisted. And in the course of time this developed into the Copernican system that is taught nowadays to every child.

We can look back from this world-conception to ancient times when the prevailing picture of the universe was very different. All that has remained of it are those traditions which in the form in which they exist today—in astrology and the like—are sheer dilettantism. That is what has remained of ancient astronomy, and it has also remained, ossified and immobilized, in the symbols of certain secret societies, Masonic societies and the like. There is usually complete ignorance of the fact that these things are relics of an ancient astronomy. This ancient astronomy was quite different from that of today, for it was based, not upon mathematical principles but upon ancient clairvoyant vision.

Entirely false ideas prevail today of how an earlier humanity acquired its astronomical-astrological knowledge. This was acquired through an instinctive-clairvoyant vision of the universe. The earliest Post-Atlantean peoples saw the heavenly bodies as spirit forms, spirit entities, whereas we today regard them merely as physical structures. When the ancient peoples spoke of the celestial bodies, of the planets or of the fixed stars, they were speaking of spiritual beings. Today, the sun is pictured as a globe of burning gas which radiates light into the universe. But for the people of ancient times the sun was a living Being and they regarded the sun, which their eyes beheld, simply as the outward manifestation of this Spirit Being at the place where the sun stands in the universe; and it was the same in regard to the other heavenly bodies—they were seen as Spirit Beings. We must think of an age which came to an end long before the time of the Mystery of Golgotha, when the sun out yonder in the universe and everything in the stars was conceived of as living spirit reality, living Being.

Then came an intermediary period when people no longer had this vision, when they regarded the planets, at any rate, as physical, but still thought of them as pervaded by living souls. In times when it was no longer known how the physical passes over by stages into what is of the soul, how what is of the soul passes over by stages into the physical, how in reality the two are united, people postulated physical existence on the one side and soul existence on the other. They thought of the correspondences between these two realms just as most psychologists today—if they admit the existence of a soul at all—still think, namely that the soul and the physical nature of the human being are identical. This, of course, leads thought to absurdity; or there is the so-called ‘psycho-physical parallelism’, which again is nothing else than a stupid way of formulating something that is not understood.

Then came the age when the heavenly bodies were regarded as physical structures, circling or stationary, attracting or repelling one another in accordance with mathematical laws. To be sure, in every epoch there existed a knowledge—in earlier times a more instinctive knowledge—of how things are in reality. But in the present age this instinctive knowledge no longer suffices; what in earlier times was known instinctively must now be acquired by conscious effort. And if we inquire how those who were able to view the universe in its totality—that is to say, in its physical, psychical and spiritual aspects—if we inquire how these people pictured the sun, we must say: They pictured it first and foremost as a Spirit-Being. Those who were initiated conceived of this Spirit-Being as the source of the moral. In my Philosophy of Spiritual Activity I have said that 'moral intuitions' are drawn from this source—but drawn from it in the earthly world, for the moral intuitions shine forth from us, from what can live in us as enthusiasm for the moral.

Think of how greatly our responsibility is increased when we realize: If here on the earth there were no soul capable of being fired with enthusiasm for true and genuine morality, for the spiritual moral order in general, nothing could be contributed towards the progress of our world, towards a new creation; our world would be led towards its death.

This force of light that is on the earth (diagram VII) rays out into the universe. This is, to begin with, imperceptible to ordinary vision; we do not perceive how human moral impulses ray out from the earth into the universe. If a grievous age were to dawn over the earth, an age when millions and millions of people would perish through lack of spirituality—spirituality conceived of here as including the moral, which indeed it does—if there were only a dozen people filled with moral enthusiasm, the earth would still ray out a spiritual, sun-like force! This force rays out only to a certain distance. At this point it mirrors itself, as it were, in itself, so that here (diagram VIII) there arises the reflection of what radiates from humans. And in every epoch the initiates regarded this reflection as the sun. For as I have so often said, there is nothing physical here. Where ordinary astronomy speaks of the existence of an incandescent globe of gas, there is merely the reflection of a spiritual reality in physical appearance.

You see, therefore, how great is the distance separating the Copernican view of the world, and even the old astrology, from what was the inmost secret of Initiation. The best illustration of these things is provided by the fact that in an epoch when great power was vested in the hands of groups of people, who, as they declared, considered that such truths were dangerous for the masses and did not wish them to be communicated, one who was an idealist—the Emperor Julian (called for this reason ‘the Apostate’)—wanted to impart these truths to the world and was then brought to his death by cunning means. There are reasons which induce certain occult societies to withhold vital secrets of world-existence, because by so doing they are able to wield a certain power. If in the days of the Emperor Julian certain occult societies guarded their secrets so strictly that they acquiesced in his murder, it need not surprise us if those who are the custodians of certain secrets today do not reveal them but want to withhold them from the masses in order to enhance their power—it need not surprise us if such people hate to realize that at least the beginnings of such secrets are being unveiled. And now you will understand some of the deeper reasons for the bitter hatred that is leveled against Spiritual Science, against what Spiritual Science feels it a duty to bring to mankind at the present time. But we are living in an age when either earthly civilization will be doomed to perish, or certain secrets will be restored to mankind—truths which hitherto have in a certain way been guarded as secrets, which were once revealed to people through instinctive clairvoyance but must now be reacquired by fully conscious vision, not only of the physical but also of the spiritual that is within the physical.

What was the real aim of Julian the Apostate?—He wished to make clear to the people: You are becoming more and more accustomed to look only at the physical sun; but there is a spiritual Sun of which the physical sun is only the mirror-image! In his own way he wished to communicate the Christ-Secret to the world. But in our age it is desired that the connection of Christ, the spiritual Sun, with the physical sun, shall be kept hidden. That is why certain authorities rage most violently of all when we speak of the Christ Mystery in connection with the Sun Mystery. All kinds of calumnies are then spread abroad.—But Spiritual Science is assuredly a matter of importance in the present age, and those alone who regard it as such view it with the earnestness that is its due.

As human beings we stand in the world as thinking, contemplative beings on the one hand, and as doers, as beings of action, on the other; with our feelings we live within both these spheres. With our feelings we respond, on the one side, to what is presented to our observation; on the other side, feelings enter into our actions, our deeds. We need only consider how we may be satisfied or dissatisfied with the success or lack of success of our deeds, how in truth all action is accompanied by impulses of feeling, and we shall see that feeling links the two poles of our being: the pole of thinking and the pole of deed, of action. Only through the fact that we are thinking beings are we human in the truest sense. Consider too, how everything that gives us the consciousness of our essential humanity is connected with the fact that we can inwardly picture the world around us; we live in this world and can contemplate it. To imagine that we cannot contemplate the world would entail forfeiting our essential humanity.

As doers we have our place in social life and everything we accomplish between birth and death has a certain significance in this social life. Insofar as we are contemplative beings, thought operates in us; insofar as we are doers, that is to say, social beings, will operates in us. It is not the case in human nature, nor is it ever so, that things can simply be thought of intellectually side by side; the truth is that whatever is an active factor in life can be characterized from one aspect or another; the forces of the world interpenetrate, flow into each other. Mentally we can picture ourselves as beings of thought and also as beings of will. But even when we are entirely engrossed in contemplation, when the outer world is completely stilled, the will is continually active. And again, when we are performing deeds, thought is active in us. It is inconceivable that anything should proceed from us in the way of actions or deeds—which may also take effect in the realm of social life—without our identifying ourselves in thought with what thus takes place. In everything that is of the nature of will, the element of thought is contained; and in everything that is of the nature of thought, will is present. It is essential to be quite clear about what is involved here if we seriously want to build the bridge between the moral-spiritual world order and natural-physical world order.

Imagine that you are living for a time purely in reflection as usually understood, that you are engaging in no kind of outward activity at all, but are wholly engrossed in thought. You must realize, however, that in this life of thought, will is also active; will is then at work in your inner being, raying out its forces into the realm of thought. When we picture the thinking human being in this way, when we realize that the will is radiating all the time into the thoughts, something will certainly strike us concerning life and its realities. If we review all the thoughts we have formulated, we shall find in every case that they are linked with something in our environment, something that we ourselves have experienced. Between birth and death we have, in a certain respect, no thoughts other than those brought to us by life. If our life has been rich in experiences we have a rich thought content; if our life experiences have been meager, we have a meager thought content. The thought content represents our inner destiny—to a certain extent. But within this life of thought there is something that is inherently our own; what is inherently our own is how we connect thoughts with one another and dissociate them again, how we elaborate them inwardly, how we arrive at judgments and draw conclusions, how we orientate ourselves in the life of thought—all this is inherently our own. The will in our life of thought is our own.

If we study this life of thought in careful self-examination, we shall certainly realize that thoughts, as far as their actual content is concerned, come to us from outside, but that it is we ourselves who elaborate these thoughts. Therefore, in respect to our world of thought we are entirely dependent upon the experiences brought to us by our birth, by our destiny. But through the will, which rays out from the depths of the soul, we carry into what thus comes to us from the outer world, something that is inherently our own. For the fulfillment of what self-knowledge demands of us it is highly important to keep separate in our minds how, on the one side, the thought content comes to us from the surrounding world and how, on the other, the force of the will, coming from within our being, rays into the world of thought.

How, in reality, do we become inwardly more and more spiritual?—Not by taking in as many thoughts as possible from the surrounding world, for these thoughts merely reproduce in pictures this outer world, which is a physical, material world. Constantly to be running in pursuit of sensations does not make us more spiritual. We become more spiritual through the inner, will-permeated work we carry out in our thoughts. This is why meditation, too, consists in not indulging in haphazard thoughts but in holding certain easily envisaged thoughts in the very center of our consciousness, drawing them there with a strong effort of will. And the greater the strength and intensity of this inner radiation of will into the sphere of thinking, the more spiritual we become. When we take in thoughts from the outer material world—and between birth and death we can take in only such thoughts—we become, as you can easily realize, unfree; for we are given over to the concatenations of things and events in the external world; as far as the actual content of the thoughts is concerned, we are obliged to think as the external world prescribes; only when we elaborate the thoughts do we become free in the real sense.

It is possible to attain complete freedom in our inner life if we increasingly efface and exclude the actual thought content, insofar as this comes from outside, and kindle into greater activity the element of will which streams through our thoughts when we form judgments, draw conclusions and the like. Thereby, however, our thinking becomes what I have called in my Philosophy of Spiritual Activity ‘pure thinking’. We think, but in our thinking there is nothing but will. I have laid particular emphasis on this in the new edition of the book (1918). What is thus within us lies in the sphere of thinking. But pure thinking may equally be called pure will. Thus from the realm of thinking we reach the realm of will, when we become inwardly free; our thinking attains such maturity that it is entirely irradiated by will; it no longer takes anything in from outside, but its very life is of the nature of will. By progressively strengthening the impulse of will in our thinking we prepare ourselves for what I have called in the Philosophy of Spiritual Activity, ‘Moral Imagination’. Moral Imagination rises to the 'Moral Intuitions' which then pervade and illuminate our will that has now become thought, or our thinking that has now become will. In this way we raise ourselves above the sway of the 'necessity' prevailing in the material world, permeate ourselves with the force that is inherently our own, and prepare for Moral Intuition. And everything that can stream into us from the spiritual world has its foundation, primarily, in these Moral Intuitions. Therefore freedom dawns when we enable the will to become an ever mightier and mightier force in our thinking.

Now let us consider the human being from the opposite pole, that of the will. When does the will present itself with particular clarity through what we do? When we sneeze, let us say, we are also doing something, but we cannot, surely, ascribe to ourselves any definite impulse of will when we sneeze! When we speak, we are doing something in which will is undoubtedly contained. But think how, in speaking, deliberate intent and absence of intent, volition and absence of volition, intermingle. You have to learn to speak, and in such a way that you are no longer obliged to formulate each single word by dint of an effort of will; an element of instinct enters into speech. In ordinary life at least, it is so, and it is emphatically so in the case of those who do not strive for spirituality. Garrulous people, who are always opening their mouths in order to say something or other in which very little thought is contained, give others an opportunity of noticing—they themselves, of course, do not notice—how much there is in speech that is instinctive and involuntary. But the more we go out beyond our organic life and pass over to activity that is liberated, as it were, from organic processes, the more do we carry thoughts into our actions and deeds. Sneezing is still entirely a matter of organic life; speaking is largely connected with organic life; walking really very little; what we do with the hands, also very little. And so we come by degrees to actions which are more and more emancipated from our organic life. We accompany such actions with our thoughts, although we do not know how the will streams into these thoughts. If we are not somnambulists and do not go about in this condition, our actions will always be accompanied by our thoughts. We carry our thoughts into our actions, and the more our actions evolve towards perfection, the more are our thoughts being carried into them.

Our inner life is constantly deepened when we send will, our own inherent force, into our thinking, when we permeate our thinking with will. We bring will into thinking and thereby attain freedom. As we gradually perfect our actions we finally succeed in sending thoughts into these actions; we irradiate our actions—which proceed from our will—with thoughts. On the one side (inwards) we live a life of thought; we permeate this with the will and thus find freedom. On the other side (outwards) our actions stream forth from our will, and we permeate them with our thoughts.

But by what means do our actions evolve to greater perfection? How do we achieve greater perfection in our actions? We achieve this by developing in ourselves the force which can only be designated by the words: devotion to the outer world.—The more our devotion to the outer world grows and intensifies, the more does this outer world stir us to action. But it is just through unfolding devotion to the outer world that we succeed in permeating our actions with thoughts. What, in reality, is devotion to the outer world? Devotion to the outer world, which permeates our actions with thoughts, is nothing else than love.

Just as we attain freedom by irradiating the life of thought with will, so do we attain love by permeating the life of will with thoughts. We unfold love in our actions by letting thoughts radiate into the realm of the will; we develop freedom in our thinking by letting what is of the nature of will radiate into our thoughts. And because, as human beings, we are a unified whole, when we reach the point where we find freedom in the life of thought and love in the life of will, there will be freedom in our actions and love in our thinking. Each irradiates the other: action filled with thought is wrought in love; thinking that is permeated with will gives rise to actions and deeds that are truly free.

Thus you see how in the human being the two great ideals, freedom and love, grow together. Freedom and love are also that which we, standing in the world, can bring to realization in ourselves in such a way that, through us, the one unites with the other for the good of the world.

We must now ask: How is the ideal, the highest ideal, to be attained in the will-permeated life of thought?—If the life of thought were something that represented material processes, the will could never penetrate fully into the realm of the thoughts and increasingly take root there. The will would at most be able to ray into these material processes as an organizing force. Will can take real effect only if the life of thought is devoid of outer, physical reality. What, then, must it be?

You will be able to envisage what it must be if you take a picture as a starting point. If you have here a mirror and here an object, the object is reflected in the mirror; if you then go behind the mirror, you find nothing. In other words, you have a picture—nothing more. Our thoughts are pictures in this same sense. How is this to be explained?—In a previous lecture I said that the life of thought as such is not a reality of the immediate moment. The life of thought rays in from our existence before birth, or rather, before conception. The life of thought has its reality between death and a new birth. And just as here the object stands before the mirror and what it presents is a picture—only that and nothing more—so what we unfold as the life of thought is lived through in the real sense between death and a new birth, and merely rays into our life since birth. As thinking beings, we have within us a mirror reality only. Because this is so, the other reality which, as you know, rays up from the metabolic process, can permeate the mirror pictures of the life of thought. If, as is very rarely the case today, we make sincere endeavors to develop unbiased thinking, it will be clear to us that the life of thought consists of mirror-pictures if we turn to thinking in its purest form—in mathematics. Mathematical thinking streams up entirely from our inner being, but it has a mirror-existence only. Through mathematics the make-up of external objects can, it is true, be analyzed and determined, but the mathematical thoughts in themselves are only thoughts, they exist merely as pictures. They have not been acquired from any outer reality.

Abstract thinkers such as Kant also employ an abstract expression. They say: mathematical concepts are a priori.—A priori, apriority, means ‘existing in the mind independent of experience’. But why are mathematical concepts a priori? Because they stream in from the existence preceding birth, or rather, preceding conception. It is this that constitutes their ‘apriority’. And the reason why they appear real to our consciousness is because they are irradiated by the will. This is what makes them real. Just think how abstract modern thinking has become when it uses abstract words for something which, in its reality, is not understood! Men such as Kant had a dim inkling that we bring mathematics with us from our existence before birth, and therefore they called the findings of mathematics ‘a priori’. But the term ‘a priori’ really tells us nothing, for it points to no reality, it points to something merely formal.

In regard to the life of thought, which with its mirror existence must be irradiated by the will in order to become reality, ancient traditions speak of semblance. (Diagram XI, Schein.)

Let us now consider the other pole of man's nature, where the thoughts stream down towards the sphere of will, where deeds are performed in love. Here our consciousness is, so to speak, held at bay; it rebounds from reality. We cannot look into that realm of darkness—a realm of darkness for our consciousness—where the will unfolds whenever we raise an arm or turn the head, unless we take super-sensible conceptions to our aid. We move an arm; but the complicated process in operation there remains just as hidden from ordinary consciousness as what takes place in deep sleep, in dreamless sleep. We perceive our arm; we perceive how our hand grasps some object. This is because we permeate the action with thoughts. But the thoughts that are in our consciousness are still only semblance. We live in what is real, but it does not ray into our ordinary consciousness. Ancient traditions spoke here of Power (Gewalt), because the reality in which we are living is indeed permeated by thought, but thought has nevertheless rebounded from it in a certain sense, during the life between birth and death. (Diagram XI.)

Between these two poles lies the balancing factor that unites the two—unites the will that rays towards the head with the thoughts which, as they flow into deeds wrought with love, are, so to say, felt with the heart. This means of union is the life of feeling, which is able to direct itself towards the will as well as towards the thoughts. In our ordinary consciousness we live in an element by means of which we grasp, on the one side, what comes to expression in our will-permeated thought with its predisposition to freedom, while on the other side, we try to ensure that what passes over into our deeds is filled more and more with thoughts. And what forms the bridge connecting both has since ancient times been called Wisdom. (Diagram XI.)

In his fairy tale, The Green Snake and the Beautiful Lily, Goethe has given indications of these ancient traditions in the figures of the Golden King, the Silver King, and the Brazen King. We have already shown from other points of view how these three elements must come to life again, but in an entirely different form—these three elements to which ancient instinctive knowledge pointed and which can come to life again only if we acquire the knowledge yielded by Imagination, Inspiration, and Intuition.

But what is it that is actually taking place as we unfold our life of thought?—Reality is becoming semblance! It is very important to be clear about this. We carry about with us our head, which with its hard skull and tendency to ossification, presents, even outwardly, a picture of what is dead, in contrast to the rest of the living organism. Between birth and death we bear in our head that which, from an earlier time when it was reality, comes into us as semblance. From the rest of our organism we permeate this semblance with the element issuing from our metabolic processes; we permeate it with the real element of the will. There we have within us a seed, a germinating entity which, first and foremost, is part of our humanity, but also means something in the cosmos. Think of it—an individual is born in a particular year; before then she was in the spiritual world. When she passes out of the spiritual world, thought which there is reality, becomes semblance, and she leads over into this semblance the forces of her will which come from an entirely different direction, rising up from parts of her organism other than the head. That is how the past, dying away into semblance, is kindled again to become reality of the future.

Let us understand this rightly. What happens when we rise to pure thinking, to thinking that is irradiated by will?—On the foundation of the past that has dissolved into semblance, through fructification by the will which rises up from our egohood, there unfolds within us a new reality leading into the future. We are the bearers of the seed into the future. The thoughts of the past, as realities, are as it were the mother-soil; into this mother-soil is laid that which comes from the individ ual egohood, and the seed is sent on into the future for future life.

On the other side, we evolve by permeating our deeds and actions, our will-nature, with thoughts; deeds are performed in love. Such deeds detach themselves from us. Our deeds do not remain confined to ourselves; they become world happenings. If they are permeated by love, then love goes with them. As far as the cosmos is concerned, an egotistical action is different from an action permeated by love. When, out of semblance, through fructification by the will, we unfold that which proceeds from our inmost being, then what streams forth into the world from our head encounters our thought-permeated deeds. Just as when a plant unfolds it contains in its blossom the seed to which the light of the sun, the air outside, and so on, must come, to which something must be brought from the cosmos in order that it may grow, so what is unfolded through freedom must find an element in which to grow through the love that lives in our deeds.

Thus do we stand within the great process of world evolution, and what takes place inside the boundary of our skin and flows out beyond our skin in the form of deeds, has significance not only for us but for the world, the universe. We have our place in the arena of cosmic happenings. By reality in earlier times becoming semblance in us, reality is ever and again dissolved, and in that the semblance is quickened again by the will, new reality arises. Here we have—as if spiritually we could put our very finger upon it—what has also been spoken of from other points of view.—There is no eternal conservation of matter! Matter is transformed into semblance and semblance is transformed into reality by the will. The law of the conservation of matter and energy affirmed by physics is a delusion, because account is taken of the natural world only. The truth is that matter is continually passing away in that it is transformed into semblance; and a new creation takes place in that through the human being, who stands before us as the supreme achievement of the cosmos, semblance is again transformed into Being (Sein).

We can also see this if we look at the other pole—only there it is not so easy to perceive. The processes which finally lead to freedom can certainly be grasped by unbiased thinking. But to see rightly in the case of this other pole needs a certain degree of spiritual-scientific development. For here, to begin with, ordinary consciousness rebounds when confronted by what ancient traditions called Power. What is living itself out as Power, as Force, is indeed permeated by thoughts; but the ordinary consciousness does not perceive that just as more and more will, a greater and greater faculty of judgment, comes into the world of thought, so, when we bring thoughts into the will-nature, when we overcome the element of Power more and more completely, we also pervade what is merely Power with the light of thought. At the one pole of man's being we see the overcoming of matter; at the other pole, the new birth of matter.

As I have indicated briefly in my book, Riddles of the Soul (Mercury Press, 1996), the human being is a threefold being: as nerve-and-sense being, the bearer of the life of thought, of perception; as rhythmic being (breathing, circulating blood), the bearer of the life of feeling; as metabolic being, the bearer of the life of will. But how then does the metabolic process operate in us when will is ever more and more unfolded in love? It operates in that, as we perform such deeds, matter is continually overcome. And what is it that unfolds in us when, as a free being, we find our way into pure thinking, which is, however, really of the nature of will?—Matter is born!—We behold the coming-into-being of matter! We bear in ourselves that which brings matter to birth: our head; and we bear in ourselves that which destroys matter, where we can see how matter is destroyed: our metabolic-limb organism.

This is the way in which to study the whole human being. We see how what consciousness conceives of in abstractions is an actual factor in the process of World-Becoming; and we see how that which is contained in this process of World-Becoming and to which the ordinary consciousness clings so firmly that it can do no other than conceive it to be reality—we see how this is dissolved into nothingness. It is reality for the ordinary consciousness, and when it obviously does not tally with outer realities, then recourse has to be taken to the atoms, which are considered to be firmly fixed realities. And because one cannot free oneself in one's thoughts from these firmly fixed realities, one lets them mingle with each other, now in this way, now in that. At one time they mingle to form hydrogen, at another, oxygen; they are merely differently grouped. This is simply because people are incapable of any other belief than that what has once been firmly fixed in thought must also be as firmly fixed in reality.

It is nothing else than feebleness of thought into which one lapses when accepting the existence of fixed, ever-enduring atoms. What reveals itself to us through thinking that is in accordance with reality is that matter is continually dissolved away to nothingness and continually rebuilt out of nothingness. It is only because whenever matter dies away, new matter comes into being, that people speak of the conservation of matter. They fall into the same error into which they would fall, let us say, if a number of documents were carried into a house, copied there, but the originals burned and the copies brought out again, and then they were to believe that what was carried in had been carried out—that it is the same thing. The reality is that the old documents had been burned and new ones written. It is the same with what comes into being in the world, and it is important for our knowledge to advance to this point. For in that realm of the human being, where matter dies away into semblance and new matter arises, there lies the possibility of freedom, and there lies the possibility of love. And freedom and love belong together, as I have already indicated in my Philosophy of Spiritual Activity.

Those who, on the basis of some particular conception of the world, speak of the imperishability of matter, annul freedom on the one side and the full development of love on the other. For only through the fact that in us the past dies away, becomes semblance, and the future is a new creation in the condition of a seed, does there arise in us the feeling of love, the devotion to something to which we are not coerced by the past, and freedom, action that is not predetermined. Freedom and love are, in reality, comprehensible only to a spiritual-scientific conception of the world, not to any other. Those who are conversant with the picture of the world that has appeared in the course of the last few centuries will be able to assess the difficulties that will have to be overcome before the habits of thought prevailing in modern humanity can be induced to give way to this unbiased, spiritual-scientific thinking. For in the picture of the world existing in natural science there are really no points from which we can go forward to a true understanding of freedom and love.

How the natural-scientific picture of the world on the one side, and on the other, the ancient, traditional picture of the world, are related to a truly progressive, spiritual-scientific development of humanity—of this we will speak on some other occasion.

I should like, first of all, to speak to you about certain principles in medical study. Medical study today is based upon a scientific conception of the world, or, better said, upon scientific interpretations, which do not lead to the human being in his reality and which at the present time are not capable of giving a true description of the human being.

And so young physicians approach a sick human being without having any real picture of a healthy human being. For if, after having studied anatomy and physiology, we picture the essence of the human organism to be the organs, systems of organs, bones, muscles, all with their definite contours, and get into the habit of looking at these systems within rigid contours, we have an entirely erroneous view of the human being. All that is drawn and pictured in this way and then becomes the content of knowledge, is in reality involved in a perpetual process of becoming, in a perpetual process of build-up and breakdown (anabolism and catabolism). There is perpetual becoming, perpetual arising, and passing away. If we think deeply about this process of arising and passing away, it is at once apparent that we must pass over from what has contours within the human organism to what is fluid and has, therefore, no contours. We realize that the human being must be pictured as the product of streamings—which persist at certain locations—and that we must add to the solid body (which is, after all, the smallest part of the human being) the fluid man, if I may so express myself, the being who is no longer subject to the laws to which the bodies with definite contours are subject. The conceptions arising from modern anatomy and physiology usually give rise to the opinion that if fluid is taken to quench thirst and then more and more fluid is taken, the fourth or fifth glassful passes through the same process in the organism as does the first. But this is not the case. Up to the point where the thirst is quenched, the first glass of water passes through a complicated process; the second glass of water, when the thirst is no longer so intense, passes through the organism without this process, much more rapidly than the first. It does not go through the complicated ways of the first, and in the case of the second glass of water, what takes place is simply a kind of increased streaming of the fluid man, if I may put it so.

A true knowledge of the human being must, therefore, reckon, to begin with, with the sharply outlined organs but also with what is in flow in the organism. Physiology does, of course, also speak of what is in flow, but the flowing fluids in the human organism are only investigated from the point of view of the laws of dynamics or mechanics. The truth is that the moment the fluid man comes into consideration, we must realize that the so-called etheric body is working in this fluid man.

The drawings to be found in books on anatomy have merely to do with the human physical body. The streaming of the fluids in the organism is left out of account. This streaming of fluids within the organism is not dependent upon earthly forces, fundamentally speaking. It is dependent upon planetary forces. Therefore, we must realize that as long as we are concerned with rigidly outlined organs and systems of organs, earthly forces, pure and simple, come into consideration. The moment we are concerned with what is in circulation, whether it be the circulation of the digestive juice or of the digestive juice that has already been transformed in the blood, the ruling forces are not earthly but planetary. We will go into this more closely. It is merely a question, now, of the principle.

Thus, the physical laws of the physical body apply to the solid man; while the laws of the etheric body rule the fluid Man. But the aeriform, the gaseous, also plays a part in the human organism, a greater part, indeed, than is conjectured. Insofar as the gaseous works within and enlivens the human organism, it is entirely dependent upon the astral body. Human breathing, for instance, in its physical manifestation, is a function of the astral body.

I spoke of the physical man (physical body), of the fluid man (etheric body), of the gaseous man (astral body). So far as the fourth man, the warmth man, is concerned, there is not the slightest doubt that differentiated warmth is present in the space physically occupied by the human being, and even beyond this. If you put a thermometer behind the ear or under the armpit you will find evidence of differentiation in the warmth organism; the degrees of warmth are everywhere different. As the liver has its definite place in the organism, and the intestinal organs have theirs, so do they also have quite different temperatures. The liver temperature is quite different, for the liver has a very special kind of warmth organization. This warmth organization is subject to the ego organization.

Now, and really for the first time, you can picture the human being, insofar as he bears within himself the substances that exist on the earth in the solid, fluid, aeriform, and warmth conditions. The warmth is ruled from the ego organization. When something or other is in a certain condition of warmth, this condition of warmth has an effect upon what it is permeating. And here we come to how things really are as regards the ego organization. What the ego organization does in the human organism is done by way of the warmth organization. Suppose I am walking, simply walking. When I am walking, I take hold of my warmth organization with my ego organization. What the warmth does within the fluids which fill out the solid constituents of the legs is, indirectly, a consequence of the ego organization, but the ego organization only takes direct hold within the warmth organization. In the whole organism, in the solids, fluids, gases, and warmth, therefore, we see the intervention of the ego organization, but the intervention takes place by way of the warmth organization. The astral body also intervenes in the whole organism, but the astral body takes direct hold only in the aeriform organization, and so on. You can work out the rest for yourselves.

This helps you to understand something else. If you take what is presented to you today in physiology and anatomy all that is so beautifully drawn and is regarded as being the whole man, if you take this, you will never be able to pass over from this human being (who in reality does not exist in this form) to the soul, let alone to the spiritual. Just tell me where and how the soul or spirit could possibly be connected with the human being as pictured by physiology or anatomy today? This is the reason why all kinds of apparently well-thought-out theories have arisen concerning the interactions that take place between the soul and spirit and the body. The most ingenious of them—No, I ought to say the most nonsensical—is that of psycho-physical parallelism. It is said that the life of soul and spirit and the bodily life run their courses simultaneously and parallel to each other. No attempt is made to find a bridge. But the moment you pass on to the differentiation of the warmth and see therein the intervention of the ego organization, you realize: Yes, it is conceivable that the ego organization intervenes in the warmth ether, and by way of the warmth organization in the whole human being, down to the sharply outlined physical organization.

The reason why the bridge between the physical nature and the life of soul in the human being could not be found was because no account was taken of the existence of these organizations of which the soul and spirit take hold in successive stages. It is a known fact that the simple psychical condition of fear, for example, affects the bodily warmth. It is inconceivable that the psychical experience of fear should be capable of actually making the legs tremble. The thing is inconceivable, so a theory like that of psycho-physical parallelism has arisen. But it is conceivable that the organization of soul which is anchored in the warmth ether should be affected by fear, and then that the fear should live itself out in the corresponding change of the warmth, the warmth organization communicates itself to the airy organization, the fluid organization, and downwards to the solid body of the human being. Only in this way is it possible to build a bridge from the physical to the life of soul.

Unless you have this insight into the healthy human being you will never get insight into the sick human being. Take, for example, some part of the human organization, such as the liver or kidneys. In the so-called normal state, the liver or kidney receives impulses from the ego organization inasmuch as these impulses of the ego organization take hold, first of all, of the warmth organization and then pass down to the liver or kidney with its definite outlines. If we understand this process, it is possible to conceive that this intervention on the part of the ego by way of the warmth organization may cause the ordinary process of this warmth organization to be inwardly intensified, to deviate from its ordinary process, in such a way that the ego organization works too strongly upon the warmth organization in the liver or the kidneys. A certain state of balance must prevail in the organism in order that the ego organization can work in it. If this balance is upset, the organism may fall ill. But the organism as pictured by modern anatomy and physiology is, in reality, incapable of illness. From whence could the condition of illness possibly proceed? Somewhere or other the possibility of illness must exist in the organism. Now, the ego organization must work in with a certain strength upon the heart, that is to say, by way of the warmth organization upon the heart. Suppose it happens through some circumstance or other, and remember that in the external world, too, warmth can be guided to some other place where it is not desirable—suppose it happens that what ought to work by way of the warmth organization upon the heart works in the kidneys or liver. Something happens that must happen, but here it is out of place, has gone astray—and then the possibility of illness arises.

Only by remembering this principle will you begin to understand the possibility of illness; otherwise you will not understand. You will have to say to yourselves: Everything that goes on in the human organism is a process of nature. Illness is, however, also a process of nature. Where does a healthy process cease? Where does a process of disease begin? These questions are unfortunately unanswerable if you go no further than the teachings of orthodox physiology and anatomy. You can only get a conception of the possibility of illness when you know that what constitutes illness when it takes place in the liver, may be healthy when it takes place in the heart and so on. For if the human organism, working from out of the ego organization, could not bring forth the warmth that must be present in the region of the heart, the organism would, for example, be unable to think, to feel. But if these same forces were to invade the liver or kidneys it becomes necessary to drive them out again, to put them back, as it were, within their original boundaries. Now, in external nature there are substances and activities of substances which can take over, in the case of every organ, the activity of the etheric body, of the astral body, of the ego organization. Suppose the ego organization is taking too strong a hold of the kidneys. By giving equisetum arvense in a certain way, you enable the kidneys to do what the ego organization is doing in this abnormal, pathological condition. In this pathological condition, the ego organization is taking hold of the kidneys but in the way that ought only to happen in the heart, not in the kidneys. Something is going on in the kidneys which ought not to be there but which is there because the ego organization is pouring in its activity too intensely. We only get rid of this condition if we introduce artificially into the kidneys an activity which is an equivalent of this activity of the ego organization. That is what you can introduce into the kidneys if you really succeed in making equisetum arvense active in the kidneys. The kidneys have a great affinity with equisetum arvense. The activity of this substance throws itself into the kidneys, and the ego organization is sent out. And when the ego organization is given back to its own tasks it has a curative influence upon the diseased organ. You can call up the higher bodies, so-called, into health-giving activity when you drive them out of the diseased organ and set them again at their own proper tasks. Then, through a reactionary force which arises, these higher bodies can actually work curatively upon the diseased organ.

If we are to understand such forces and the connection of the human organism with the cosmos and with the three kingdoms of nature around man on the earth, we must cultivate a different kind of natural science from what is cultivated today. I will give you an example.

You all know that formic acid comes from ants. Certain things are known by chemists and pharmaceutical chemists about formic acid, but the following is not known. A forest in which no ants are carrying on their work causes great harm to the earth through the roots that are falling into decay. In the organic fragments that are falling into dust the earth goes to pieces. Just think of wood from which the vegetative process has gone and which has passed over into a kind of mineral condition; it is pulverized, is falling into dust. But when the ants are doing their work, formic acid in an extremely high potency is always present in the soil and in the air within the area of the forest. This formic acid permeates what is falling into dust and the connection of the formic acid with the dust safeguards the development of the earth; the dust is not just scattered away in the universe but can provide material for the earth's further evolution. Substances which seem merely to be the excretions of insects or other forms of animal life are seen, in very truth, to be the saviors of the further evolution of the earth when we know what their true function is.

The way in which the modern chemist investigates substances will never lead to a knowledge of the cosmic tasks of these substances. And without knowledge of the cosmic tasks of substances it is quite impossible to know the tasks of substances that are introduced into the human being. What formic acid does in external nature, quite without being noticed, is going on all the time within the human organism. And so I said in another lecture that the human organism must always have a certain quantity of formic acid in it because the formic acid restores the physical substances that are succumbing to the process of growing old. In certain cases it may be found that the patient has too little formic acid in his organism. It is essential to know that the different organs must each have different quantities of formic acid. When we discover that some organ has too little formic acid, this substance must be introduced into the organism. There will be cases where the introduction of formic acid gives no help, others again where it is a very great help. There may also be a case where the organism strongly resists the direct introduction of formic acid but will be inclined, when its oxalic acid content is increased, to manufacture formic acid itself, out of the oxalic acid. In cases where nothing can be done with formic acid, it is often necessary to apply an oxalic acid cure, because formic acid is produced out of the oxalic acid in the organism. This is only one indication of how necessary it is not only to understand the nature of the organs with definite contours but also the nature of the fluids, the fluid process outside in the cosmos as well as within the human organism. This must be known in all detail.

You see, certain processes outside in nature which are occasioned by man can be observed, but their whole significance cannot be revealed by scientific interpretations. Let me tell you about a very simple phenomena. Fig trees grow in the South. There are fig trees which produce wild figs and specially cultivated trees which produce sweet figs. People are shrewd in the way they produce sweet figs. They do the following: they cause a certain species of wasp to lay eggs in a fig, an ordinary fig. A wasp maggot comes from this germ and passes into the chrysalis stage. This process is interrupted and the young wasp is caused to lay a second lot of eggs in the same season. The result of this second lot of eggs from the wasps which have been generated in the same year is that sweetness is produced in the fig in which the second generation of wasps has laid eggs. In the South, people take figs that are nearly ripe, tie two together with string and hang them on a branch. The wasps come and deposit the eggs in the figs; the ripening process is very much accelerated through the fruit being cut away from the tree and the first generation of wasps develop very quickly; then the wasps go over to other figs that have not been cut, and they become very much sweeter.

This process is very important because here, within the fig substance itself, there takes place, in concentration, the same thing that happens when wasps, or, if you will, bees, take nectar from the flowers into the hive and produce honey. The bees take the nectar from the flowers and then produce honey in the hive. This same process takes place within the fig itself. The people in the South set a honey-producing process going in the fig by way of the young generation of wasps. A honey-producing process is generated in the fig which is inoculated by the young generation of wasps.

Here you have the metamorphosis of two nature processes. The one is spread out, so to say, over nature, when the bee fetches the nectar from the flowers at a distance and produces honey from this nectar in the hive. The other process is concentrated in the same tree on which the two figs are hung. These figs ripen more quickly, and the generation of wasps arises more quickly; other figs are inoculated and these become sweet. We must study such processes of nature for they are the processes which come into consideration in medical work.

There are processes at work within the human being of which modern physiology and anatomy have not the slightest inkling because their observation does not extend to nature processes such as I have now described. We must observe the more delicate processes in nature and then we shall unfold a real knowledge of the human being. For all these things, my dear friends, an inner understanding of nature is required and a comprehensive view of the warmth, the streamings of air, the warming and cooling of the air, the play of the sun's rays in this warming and cooling of air, the water vapor in the atmosphere, the wonderful play of the morning dew over the flowers and plants, the marvelous process which takes place, for example, in a gall apple which is also produced by a wasp's sting and the laying of an egg. A sense for nature is required in all these things. And this sense for nature is certainly not present when, as in the modern way of observation, everything is made dependent on what is seen under the microscope where things are taken right away from nature. There is a dreadful illusion here. What is the aim of looking through the microscope? The aim is to be able to see what cannot be seen by the ordinary eye. When the object is enormously magnified people imagine that its workings will be the same as they are in the minute. But in microscopy we are looking at something that is untrue. Microscopy is only of value if you yourselves have a sufficiently true sense for nature to be able, with your own inner activity, to modify the particular object to the corresponding minuteness. Then the whole thing is different. If you see an object magnified, you must be able to reduce it again, simply through its own inner nature. This is not done in the ordinary way. As a rule, people have no inkling of the fact that the magnitudes of the things of nature are not relative. The theory of relativity is great and fine and in most domains simply incontestable. But when it comes to the human organism, that is another matter altogether. Three years ago I was present at a discussion among certain professors. They simply did not understand when one said to them that the human organism cannot be twice as large, for example, as it actually is, for it could not endure such a size. The size of the human organism is determined by the cosmos; its size is not relative, but absolute. When the size is super-normal, as in a giant, or subnormal as in a dwarf, this immediately brings us to conditions of illness. And so when we see an object under the microscope, we see a lie, to begin with. It is a question of reducing objects back to truth, and this is possible only when we have a sense for nature, a sense for what is really happening outside in nature.

It is very important to study a beehive. The single bee is stupid; it has instincts, but it is stupid by itself. The beehive as a whole, however, is exceedingly wise. Quite recently a very interesting discussion took place with workmen at the Goetheanum to whom, in normal times, I give two lectures a week. We had been speaking of bees and a very interesting question was put. People who keep bees know quite well that when a beekeeper who is loved by the inhabitants of the hive falls ill, or dies, the whole bee population falls into disorder. This actually happens. One of the workmen who has the typically modern way of thinking said that surely a bee cannot see such a thing, it cannot possibly have any picture of the beekeeper. How, then, can such a feeling of interconnection arise? He also brought forward the point that a beekeeper looks after the hive one year but the next year there is quite a different population in the hive; even the queen bee is another insect and all the bees in the hive are young bees. How, therefore, can there be this feeling of interconnection? I answered in the following way: It is well-known that in certain periods all the substances in the human organism are changed. Suppose we make the acquaintance of someone who goes to America and comes back after ten years. The person who comes back is really quite different from the one who went away ten years ago. All the substances in his organism have been exchanged for others. Things are exactly the same as in the beehive, where the bees have changed but the feeling of the interconnection between the hive and the beekeeper remains. This feeling of interconnection is due to the fact that there is tremendous wisdom in the beehive. The hive is not merely a cluster of single bees; the hive has an individual soul, a real soul.

The perception that a beehive has a soul is also something that must form part of our sense for nature. Such perceptions are part of a true sense for nature and can be applied in many other things. We can only begin to understand the human being in health and in disease when our knowledge is reinforced by a sense for nature that is not only microscopic but also macroscopic, if I may use the expression. We shall try to understand health and disease in this way during the lectures, my dear friends, and we shall consider, too, what I will call the moral side of medical studies and medical science.

As we shall be able to make use of the eight hours at our disposal for this course of lectures, I need not hurry, and this will certainly be all to the good.

I want to develop the material given yesterday by speaking of the characteristic qualities of the several members of the human being. I spoke of the physical body which is to be connected with everything that has definite contours in the organism. There is also the fluid organism. This fluid organism is permeated with the forces of the etheric body, forces which are, however, united with the physical body as primary components of it. These are the peripherically working forces. So far as the astral body is concerned, conceptions of space will not help us at all; the astral body cannot be understood from the quantitative aspect, but only from the purely qualitative aspect. We must picture the astral body in a world that is not the world of space, as we know it, but lies outside this spatial world. And this is all the more true when we come to the ego organization.

The easiest way will be to start from the ego organization. What is this ego organization, in reality? In the physical world, it is to be perceived in the form of the physical body. In the physical world, of course, both the inner and the outer form must be included. Looking at the physical body of man as it stands in the physical world, we must realize that it has nothing fundamentally in common with the forces working in the physical world. For the moment a human being passes through the Gate of Death, and the ego organization leaves the physical body, this body begins to be subject to the forces of the external world. This means that the body is no longer built up but is destroyed. If you remember that the physical body is destroyed by the forces that are working in external nature, you will realize at once that the body cannot, in its form, be subject in any way to the forces of the physical world. When the ego organization is forming and shaping the physical body, therefore, this means that it removes the body from the forces that are present in man's earthly environment. In other words, the ego organization is something quite different from all that is to be found in the physical world.

This ego organization is connected with death. What happens in death, all at once, goes on continually throughout the period of earthly life, through the ego organization. The human being is really continually dying, but this process of dying is balanced out. To get a picture of this, think of a modified version of the legend of Penelope. Suppose you were occupied every day in doing away with a heap of earth near your house, and during the night, in your absence, someone were to come and shovel the earth back again. As long as the earth is put back you have to shovel it away again. Your activity only ceases when the heap of earth gradually gets smaller and smaller on account of decrease of activity on the part of the one who puts the earth back again. This, approximately, is a picture of the ego organization in its relation to the physical body. Nourishment of the physical body consists in bringing into it substances from the earthly environment. These substances have their own inner forces, a certain complex of forces which belongs to them, and when, for example, you take common salt as an adjunct to food, this salt, to begin with, because it comes from outside, has the same inner tendency of action which it has, as salt, in the external world. But you begin to take these qualities away from it even when it is in the mouth, and then more and more, so that, finally, if the ego organization is working properly, there is nothing any longer within you of the salt, as it was in the external world. The salt has become something completely different. The activity of the ego organization consists precisely in transforming the in-taken foodstuffs. When it is no longer possible for the physical body to take food, the ego has no more to do, just as you had no more to do when nobody was shoveling the earth heap back again. When the body is no longer capable of taking food, it is impossible for the ego to work from out of the warmth, in the physical body. We can say that death occurs when it is impossible for the ego organization to so transform the external substances that nothing remains of the outer characteristics instead of being totally in the service of the ego organization.

What does the ego organization do with the physical body? It destroys the body all the time. It does the same as death, only the process is continually balanced out by the physical body being able to take external substances as food. Ego organization and the process of nourishment, therefore, are polar opposites. The ego organization betokens for man exactly the same—but in a process of continuous activity—as death betokens, but, in death, the process is concentrated, it happens all at once. Through your ego organization you are dying all the time, that is to say, you are destroying your physical body inwardly, whereas when you die, external nature destroys your physical body outwardly. The physical body is capable of destruction in two different directions and the ego organization is simply the sum total of the destructive forces working inwards. It really seems, at first, as if the ego organization had no other task than to bring about continual death in the human being—a process that is only prevented because there is fresh reinforcement, so that this activity only begins to bring about death. In the qualitative sense, therefore, ego organization is identifiable with death, and the physical organism is identifiable with the process of nourishment. We will speak in greater detail later on.

Ego organization = Death

Physical organism = Nourishment

Between these two polar processes in the human being lie the etheric body and the astral body. Astral body and etheric body lie between the ego organization and the physical organism. The astral body, as you heard, only works directly in the aeriform part of the human organism, from there by way of the etheric body upon the fluid organism and the physical organism or organism of nourishment. In every single organ there is a working together of etheric organism and astral organism.

When the etheric organism works upon an organ, this organ is imbued with budding, sprouting life. The life force in any single organ, or in the organism as a whole, comes from the etheric organism. The astral organism has at every moment the tendency to paralyze this budding, sprouting life—not to kill it, but to damp it down, to lame it. The ego organization strives all the time to kill the organism and the single organs, and in opposition to this there must be the reinforcement from the foodstuffs taken from the external world whereby life is continually poured into the organs. This process is especially active in childhood and youth.

The etheric impulses are opposed by the activity of the astral body which damps down the etheric activity all the time. If there were only etheric activity, budding and sprouting life in your organism, you would never have a life of soul, you would never unfold consciousness and would have to vegetate in a plant existence. No consciousness unfolds in a process that is simply one of growing, budding, sprouting. For consciousness to develop, the etheric, budding and sprouting life must be damped down. Therefore in any organ where the etheric life is damped down or lamed, we have, even in normal human life, the perpetual beginning of illness. There can be no development of consciousness without this perpetual tendency to illness. If you wanted just to be healthy—well, that is possible, but then you would have to lead a vegetative existence. If you want to unfold a life of soul, if you want to have consciousness, the vegetative process must be present, but it must be damped down.

The polar contrast is not so marked between the etheric and astral organizations as it is between physical organism and ego organization, but it exists, nonetheless, in a modified form. The astral organism must continually damp down what is brought about by the etheric organism. In reality, therefore, what the astral organism does day by day in the life of man, amounts to a tendency to illness. The etheric organism brings about rampant healthiness. Just as in abstract language, we can say: Man consists of physical body, etheric body, astral body, and ego organization—so we can also say: Man consists of the process of nourishment, of the building, sprouting, health-bringing process, of the perpetually in-working processes of disease, and of a continuous dying that is checked until the death-bringing processes gather together as it were into an integer and death occurs.

Think of this astral organism with its perpetual tendency to make an organ, or the whole man, ill. Genuine observation will show you that this is so. For no feeling could arise in you if this astral organism were not present. Just picture it.

The etheric organism unfolds life and the astral organism damps down the life. In the waking state (I shall yet have to speak of sleep), there must be a continual swinging to and fro in a labile state of equilibrium, between etheric organism and astral organism. This enables a human being to feel. He would feel nothing if this swinging to and fro did not take place. But now suppose the astral activity is not immediately driven back by the etheric activity. When it is driven back, when the astral activity is driven back in statu nascendi by the etheric activity, normal feeling arises. We shall see how this is connected, in the physical, with the activity of the glands. But when the astral organism becomes more powerful, so that the organ cannot work with sufficient strength in its etheric activity, then this organ will be laid hold of too strongly by the astral activity and instead of a swinging to and fro there will arise a deformation of the organ. When the astral body oversteps the mark in this activity of damping down, when it goes beyond the process that is balanced out in statu nascendi—then the cause of illness is located in the astral body. And there is indeed such a close connection between illness and feeling that we can say: The life of feeling in man is simply the reflection, in the life of soul, of the life of illness. If there is a swinging to and fro, there underlies the life of feeling—but always in statu nascendi, in the moment of ‘becoming’—the same process which is a process of illness when the astral organism gets the upper hand.

Now it may also happen that the etheric organism gets the upper hand of the astral, which withdraws. Then there will be rampant growth, which is illness in the other direction. When the astral body gets the upper hand, inflammatory conditions arise; when the etheric activity gets the upper hand, swellings or growths appear. In the entirely normal life of feeling, a delicately poised balance is always maintained between growths and the inflammatory process. The normal life of man needs this possibility of becoming ill, only a continual balancing must take place.

Thus if we are able to perceive truly, we can see in the normal life of feeling a great deal of what is represented by the processes of illness. If we can observe such things truly, we can ascertain the approach of the illness a long time before it can be physically diagnosed, in a wrong functioning of the life of feeling. Illness is only an abnormal life of feeling in the human being.

The life of feeling lies in the realm of the soul, because a continual equalization or balancing takes place in the etheric. When the balancing no longer takes place, the life of feeling strikes down into the physical body, unites with the body. Illness is present, therefore, as soon as the life of feeling shoots down into the organ. If, in the normal way, a person can keep his feeling within the realm of soul, he is healthy. If he cannot do this, if feeling shoots down into some organ, illness arises.

I say this by way of introduction, because you will realize from it how necessary it is for the physician to have a quick and delicate eye for the soul life as well. There can be no aptitude for true diagnosis without a faculty of delicate perception for the life of soul. We will speak of details later on and this will become still more intelligible.

But now, what of the ego organization and the physical organism? Think, first, of the process of nourishment. This process of nourishment is all the time destroying the substances as they are in the external world; the astral organism damps down what the human being is, inwardly, through his etheric organism. An inner balance is established between astral organism and etheric organism. Between the ego and the physical organism there is also a balance—here between outer world and inner world. Salt, as we know it, is outer world. When the salt is taken hold of by the forces of nourishment and by the ego organization, the ego organization must be in a position completely to transform the salt as it is in the external world, to leave nothing of it behind in this form. If anything is left behind, this means that a foreign body is within the organism, but you must not merely think of this ‘foreign body’ in the organism as necessarily having definite contours, for this is least often the case. A foreign body in this sense may also be the external warmth. There should be no warmth in the organism that is not engendered by the ego organization. You must be able to conceive of a person being seized, somewhere or other, by a condition of external warmth upon which he himself does not work—it is just like a piece of wood being seized by some condition of outer warmth. An external condition of warmth may not be only a stimulus to the human being to work up a warmth of his own, but the external warmth (or cold) may begin to work directly, and this outer cold or warmth would also have to be regarded as a foreign body in itself. Thus we can say: The inner balance between illness and health is produced by the astral organism and etheric organism. The balance between the human being and the world is produced by the polar contrast between physical body and the ego organization.

The thing of importance is to get a true perception of the activities of these four members of the human organism. You realize now, surely, that illness is simply not to be understood from the external, physical organism. The process that constitutes illness lies entirely in the super-sensible. Before we can understand illness at all we must have a conception of the astral organism. And you will get this conception if you will consider the following state of things: pain arises in some organ. When the astral body becomes too powerful, the organ is ‘deformed’, and pain arises. If the organ immediately balances the influence of the astral body in statu nascendi, feeling arises. Pain is really feeling, but an enhanced feeling, proceeding from the deformation, so we can understand why illness is accompanied by pain. Without knowing this, it is very easy to ask: What is it that really causes pain in manifestations of illness? It is easy to understand why pain arises when we know that this illness is merely caused by such a strong expression of the life of feeling that this life of feeling is deforming the organ concerned. You will see now that all manifestations of feeling can be judged truly through a thorough and deep study of man's life of soul.

But these things can only be seen in their right light when we say to ourselves: Conditions differ according to which organ in the human being is laid hold of by excessive activity of the astral body. Suppose, for example, it is the liver which is being thus laid hold of by the astral body. The liver behaves quite differently from other organs. The astral body can cause much deformation without pain being produced, without pain arising exactly in the liver itself. The reason why liver diseases are so hidden, so treacherous, is because they do not announce themselves through pain. This is because the liver is an organ which, in its whole make-up, is an enclave in the human organism. There are processes in the liver which, of all processes which arise in the organism, most resemble the processes of the external world. The fact, therefore, is that in the liver, man is least man. In the liver he really ceases to be man. He becomes outer world; he has a piece of the outer world within him. This is very interesting. We have the external world; we have the human being; and within the human being, inside him, we have something like a piece of the external world. It is as if a kind of cavity were hollowed out in the organism and just as it would not hurt if the astral body were to press into this cavity, just as little is there pain when the astral body presses into the liver. The astral body can destroy but cannot cause pain where the liver is concerned, for the liver is an organ where a piece of the external world appears in the organism, as it were, in an enclave.

Without entering into such things, we shall never be able to understand the human organism. In ordinary textbooks of anatomy and physiology you will find all kinds of indications about the liver. You will understand them when you know that the liver is an organ within the human being which is most foreign to him. Why is this?

Think of an eye, or some other sense organ. It lies in a cavity which digs itself into the human being from the external world. There are processes in the human eye which can almost be explained by physics. It is easy for a physicist to speak rationally about the human eye. A physicist makes a sketch with some lines on it which, although it is all really nonsense, gives a picture of the process of the breaking-up of the light and the production of an image by an ordinary lens. The same kind of drawings are made of the eye. People draw a ray of light which passes through a lens, is broken up and then forms a picture in the background of the eye. People have really become physicists in regard to the eye and since the days of Helmholz the ear, too, has almost become a kind of piano. It has become common to apply to the sense organs conceptions that are applicable to external nature. In the sense organs, something is being continued from outside inwards, a piece of the external world is continuing

on into the inner world. There is even biological proof of this. In certain lower animals the eye is formed through an indentation which is then filled from outside. The eye is built into the organism, as it were; it does not grow out of the organism. The sense organs, therefore, are a piece of the external world within the organism. But they open outwards. In the sense organs the external world passes into the organism like a gulf. The liver is enclosed on all sides, but nonetheless it is a sense organ, a sense organ which, in the unconscious, shows a high degree of sensibility for the value of the different substances we take as foodstuffs. We can only understand what is going on in digestion, in the process of nourishment, when we no longer ascribe to the liver only those physical processes which are ascribed to it today. These processes are the expression of the spirit and soul. We must see the liver as an inner sense organ for the perception of the process of nourishment. For this reason the liver is much more closely related to the substances of the earth than are the familiar sense organs. With the eye we are exposed to the working of the ether, with the ear we are exposed to the air; but the liver is directly exposed to the qualities of the substances in the external world and it has to perceive these qualities.

The heart is a sense organ of a different kind. The perceptive faculty of the liver is exposed to external substances that come into the human being. The heart is a sense organ for perceiving the inner being of man. I have often said that it is nonsense to regard the heart as a kind of pump which drives the blood through the arteries. The movement of the blood is the result of the activity of the ego and astral body, and the heart is merely a sense organ which perceives the circulation, particularly the circulation from the lower to the upper man. The task of the liver is to perceive, in the digestive process, what value a carbohydrate, let us say, has for the human being. The task of the heart is to see how astral body and ego are working on the human being. Therefore the heart is an entirely spiritual sense organ, the liver a wholly material one. This distinction must be made. We must develop a qualitative knowledge of the organs.

What are the methods of the natural science upon which medicine is based today? Some tissue or other—it really does not matter very much which—is taken from some part of the organism, perhaps from the heart or the liver. The outer structure and make-up of this tissue are then examined. But this tells us nothing about the organ as it actually is, within the human organism. Suppose I have, here, a knife, and, there, a knife. I examine them. This is a knife, and that is a knife, only the one, when I examine its form, has a blunt edge on one side and a cutting edge on the other, and the blade is in a handle. The same could be said of the other knife—therefore the net result is, here, a knife; there, a knife. But to find the difference between a table knife and a razor I must go beyond this kind of examination. I must relate the knives to something that is a whole. Regarded externally, a razor might also be a table knife; therefore, merely from the form, I cannot know whether I have to do with a table knife or with a razor. Each thing must be observed in its whole nexus. Out of the kind of observation that is applied today to an organ, one cannot know anything about the significance of this organ in reality. It must always be regarded in the whole nexus of things. Mere examination of the structure and the make-up of an organ leads nowhere. The human being must be studied with quite different methods from those of chemistry which merely examines the chemical affinities and forces. In this respect, people are terribly naive today. In a certain physiological institute, experiments were made to see how mice could be nourished with milk. The result was splendid, for the mice flourished and became fat and big. At the same time, for the purpose of proving that there is something more in milk than its component parts, these components were separated and given to the mice. They perished within three or four days and could not be kept alive. And then people said: Milk does not only contain its known components, but it contains, as well, another substance—the vitamin. They were obliged to affirm the existence of yet another, very fine substance, namely, the vitamin. The point of importance is not the discovery of such a 'substance' but that to take the separate components of the milk is like taking a clock and looking at the brass, the silver, the other metals in it, the glass and so on. Yes, but the brass, the silver, the glass and all the other metals do not make a clock. The clock depends upon what the mind of the mechanic makes out of these substances. And in the case of milk and its components we are thinking with the mind of the mechanic, when we are concerned with the fact that earthly qualities are contained within these components—qualities which they get from the earth. Up to a certain point of time the peripheric forces from the etheric body are still present, as well as the earthly components. People must finally bring themselves to accept these things. It is not so much a question of things being hidden, and then ‘found’. The discovery of vitamins, for example, simply confirms what exists. Quite a different mode of observation must become current.

Suppose you are eating too many potatoes. You will never find out anything with the ordinary methods of investigation. It will be useless to try to ascertain the effect of potatoes in the human organism by computing the quantity of carbohydrates. The other carbohydrates which are present, for example, not in roots but in leaves or in fruits, are worked up in the digestive tract. There is something very remarkable about the potato. The potato passes with its forces so intensely into the human organism, that, what in the case of the bean happens while still within the digestive tract, happens in the case of the potato only in the brain. In the brain, too, processes of nourishment are continually taking place. I am only indicating these things in order to speak in greater detail later on. A person who eats too many potatoes may, under certain circumstances, overwork his brain. He transfers processes which ought to take place below the brain to the brain itself. It will only be possible to get something from medical science for hygiene and for social life in general by learning the relations of the human being to the substances around him, not from their chemical make-up but from their world connections. Whether a substance appears in leaf or in root constitutes a fundamental difference. It is much more important to know from which part of the plant a substance comes than to know whether it contains carbohydrates. Roots are more connected with the head organization of man; flowers and leaves more with the lower man. The chemical make-up really plays no outstanding part. The relations of the human being to the surrounding world must be learned from quite other things if we really want to understand the curative and the disease-producing factors, the disease itself, and its remedy. The heed that is paid to the indications given by abstract chemistry has really, little by little, buried all knowledge of the human being, because knowing the chemical make-up of a substance does not tell us anything about the real relations of man to the surrounding world.

Take another example—the point of view derived from chemistry is that oxygen is necessary in the air but that nitrogen is not necessary to the same extent. From what is commonly thought about oxygen and nitrogen, we might imagine that it does not matter so much to the breathing when there is too little nitrogen in the air, provided there is enough oxygen. But the truth is, that when air contains too little nitrogen, the human being gives off nitrogen in order to replace it in the air around him. The human being is so constituted that there must be a certain relation between his own nitrogen content and the nitrogen content of the surrounding air quite apart from the breathing process.

All these things are exceedingly important for an understanding of the nature of man. But although they are investigated and known, here and there, they remain fruitless for the modern world of science as long as there is no basis for understanding how man is membered into the world around him. We will try to find this basis in order to get insight into the healthy as well as the ill human being.

From tomorrow onwards I want you to think about what questions you would like to ask, and then give these questions to me so that I may remember them as these lectures go on.

Today I want to say something in direct continuation of what was said in the two preceding lectures about the nature of the human being and his relation to the world. In our anthroposophical studies here it is useless to bother about the ‘views’—in reality they are not ‘views’ at all—that are held by modern science in connection with the human being. It would be equally useless to make up our minds to deviate as little as possible from things that have become customary and habitual. For the state of affairs at present is that in certain great and significant directions the truth deviates very considerably from what has become customary. It deviates in an extraordinarily high degree. And so those who are striving after truth today will also need to have the courage to acknowledge many things that modern science would consider quite absurd. On the other hand, if you really want to heal, it will be necessary for you—not here, but in other places—to mix with those who set out to heal today by the methods customary in the external world. You will have to have dealings with science as it is in the modern world. Otherwise, among all the errors of the times, you will feel insecure with the truth you possess.

The current idea today is that there are about seventy to eighty substances on the earth, with certain forces of attraction and repulsion. These forces are supposed to work through certain atomic weights and the like. A number of theoretical laws of nature are then evolved according to which people try to find out how the substances are formed, and then, out of the different forces whose origin is looked for in the substances, a phantasmal picture is built up which is supposed to represent “man.”

But the truth is that neither in his form nor in the forces which maintain his processes of growth and nourishment is the human being subject only to the influences proceeding from the substances of the earth. In speaking of the etheric body, we found that it is entirely under the influence of forces which stream in from the periphery, from the cosmos. Taking these two kinds of forces—those which proceed from the substances of the earth, and those which stream in from the periphery—you will realize that a balancing, a harmonizing of these two kinds of forces, is necessary for each organ in the body. The several systems of organs in the human being differ very considerably in the way in which this balance is established.

Let us now consider the human head from this point of view. To begin with, attention must be called—and I have often done this—to the weight of the human brain which is very largely eliminated because the brain, with its definite outline, floats in the cerebral fluid. The brain floats in the cerebral fluid which circulates through the spinal column. The actual weight of the brain is about thirteen hundred to fifteen hundred grams. But when it is within the human being, it weighs much less—at most, twenty grams. This is because it floats in the cerebral fluid, and, according to the Law of Archimedes, every body, when it floats in fluid, loses as much of its weight as is equivalent to the weight of the volume of fluid displaced. In the fluid, the brain is subject to buoyancy so that only about twenty to twenty-five grams of its weight remains, and this is the weight with which the brain presses downwards. If it were to press downwards with its full weight there could be no blood vessels underneath it; they would be crushed. The earthly quality of heaviness is actually taken away from the brain. It is not the earthly quality of heaviness that enables us to be alive in the brain, but the buoyancy, the force that is in opposition to heaviness. In the case of the brain, this earthly heaviness amounts to, at most, twenty grams. The force of attraction exercised by the earth upon the human head is very little.

We see from this that the earthly characteristic of the brain vanishes—vanishes because of the way man is organized. The human organization is such that the earthly forces vanish. The Law of Archimedes has taught humanity about buoyancy, but it is not always taken account of in technical contrivances. I am not sure whether people realize it, but it is quite obvious that they acknowledge laws which happen to suit them and ignore those which do not. What I have told you about heaviness disappearing applies not only to the human head but to the whole inner structure of the head. Something else happens as a result of the special

arrangement of the breathing process, of certain static conditions which hold sway between in-breathing and out-breathing. When we draw a breath, a force is exercised, and then comes a counter force when we breathe out again. The relationship between this force and counter force in breathing is similar to the relationship between gravity and buoyancy.

The curious thing is that when we are walking, the head, the brain, remains at rest. On account of buoyancy, the brain is not heavy, and its inner condition of rest, its inner static condition, is not changed when we are walking. Nor is this true only of our walking, but, in a curious manner, it is especially true also of the movement we make together with the earth. We only share in the movement with the rest of the body, not with the brain. The movement is quashed, so far as the brain is concerned. We may move the head itself as rapidly as the rest of the body, but even then the brain remains at rest. It is harder to conceive that something that is momentarily in movement is, in reality, at rest, than to conceive that something that is subject to gravity is, in reality, not heavy. But it is so, nevertheless. Thinking of the inner organization of the human being, we must say that the head remains at rest all the time. All the forces adjust themselves; there is a slight pull of gravity in the downward direction, in a proportion of twenty to fifteen hundred, and in the forward direction there is a very slight propelling force of movement. In essentials, however, the movement is balanced out.

We can, therefore, say that the human head, as regards its inner existence, is like a person who is sitting quietly in an automobile and not moving at all while the car moves forward. The experience of the human head is just as it would be if it had no weight. Neither does it move when the human being moves and when the earth is moving together with the human being. The head is, therefore, a very special organ, for it excludes itself, exiles itself from what is happening on the earth; the earth only participates to a small extent in the activities of the head. The head is an image of the cosmos. In its essential nature, it has nothing to do with the forces of the earth. The inner structure of the brain is an image of the cosmic forces. Its form cannot be explained from anything of an earthly nature but only from the in-working cosmos. I must speak rather crudely here, but you will understand me. The earth works only to this extent, that it breaks through the cosmic formation and inserts into the human being that which tends towards the earth. You can see this readily by looking at a skeleton. Take away the skull and you have taken away the part of the skeleton that is an image of the cosmos. The arrangement of the ribs is only half cosmic for here the skeleton is already impressed by the earthly forces. In the long bones of the legs and the long

bones of the arms, you have a purely earthly formation. The spinal vertebrae to which the ribs are connected have arisen from the condition of equilibrium between the cosmic and the earthly. In the head, with its covering skull you have a form in which the cosmos deprives the earthly forces of the possibility of taking shape; this form of the skull is an image of the cosmos. In this way we must study the forms of the human body.

When we study the forms of the human body in this way, knowing that the inner life of the head, the soft substances and fluids of the head remain at rest and in this state of rest are an image of the cosmos, we shall realize that anatomy and physiology, as presented today, cannot really be said to be true because they do not acknowledge the existence of cosmic influences. I have spoken of forces which proceed from the periphery and stream inwards. They stream in from all sides upon the human head. But it makes a difference if these forces are intercepted by the moon, by the sun, or by Saturn. There peripheric forces are modified by the planetary bodies standing in the heavens. The directions from which these forces stream in are, therefore, not without significance. The in-streaming is essentially modified according to the position of the constellation from which it comes.

This is a thought around which there is nothing but dilettantism today, but in olden times it was the basis of great astronomical wisdom. The dreadful treatises that exist on such subjects today give no picture at all of the reality. Understanding of what I have said is essential before we can have insight into the structure and make-up of the human being. For the fact that in his head the human being is subject entirely to the cosmos, and in the long bones of arms and legs entirely to the earthly forces, is an expression, right down into substance, of how the cosmic formative forces behave. You know that human bone contains calcium carbonate. But it also contains calcium phosphate. Both substances are very important for the bones. Through the calcium carbonate the bones become subject to the earth. If the bone substance was not permeated by calcium carbonate, the earth could not approach the bones. The calcium carbonate constitutes the substantial point of contact for the earth which is thereby able to shape the bones in accordance with its formative forces. The thigh bones could not have their extension from above downwards if this was not made possible by the calcium carbonate. But there would be no femoral head without CaPO3. This fact is not changed by the objection which anatomists will raise, that the quantities of CaCO3 and CaPO3 do not essentially differ in the shaft of a long bone and its neck or head. To begin with, this statement is not quite accurate, for minute research will reveal a difference, but something else comes into consideration here. The human organism must have within it both up-building processes and processes of demolition—processes out of which something is built up and processes by means of which what is not used in the up-building is separated off.

A very decided difference between these up-building forces and forces of demolition in substances themselves is shown, for example, by fluorine. The physiologist would say that fluorine plays a part in the up-building of the teeth and is also present in the urine. Fluorine, therefore, exists here and there in the human body. But that is not the point of importance. In the up-building of the teeth, the activity of the fluorine is a positive one. The teeth could not develop without fluorine. In urine, there is fluorine which has been broken down and is excreted. The essential thing is to distinguish between whether a substance is being eliminated at some place in the body or whether it is an absolute necessity in the up-building process. If part of a bone is built in from the cosmos, as it were, CaPO3 has here an up-building activity. In another part of a bone the CaPO3 is being eliminated. In the shafts of the long bones, CaCO3 builds up, but it is being eliminated in that part of the bone which is built in from the cosmos (head of the bone). The essential thing is not the actual presence, here or there, of a substance. The point of importance is what the substance is doing, what significance it has at some particular place in the organism.

I once tried to give a picture of these things by saying the following: Suppose I am going for a walk one morning at nine o'clock and see two men sitting together on a bench. At three o'clock in the afternoon I pass the bench again and the two men are together there again. These two facts in themselves really tell me nothing, because it may be that one of the men had taken his lunch with him and had remained sitting on the bench from nine o'clock until three o'clock, while the other had gone off for a walk and had come back again just before three o'clock. One of them is quite rested, the other terribly tired. In this respect there is an inner difference between them. The point of importance is not the presence of the one person or the other, but what each of them has been doing, how has life brought him to this particular place. Therefore, so far as understanding of the human being is concerned, the presence of some substance in an organ is not really a matter of importance. It is a question of knowing in what kind of process the substance is involved—a process of up-building or a process of demolition.

We shall never find the transition from the quality of a substance that is necessary to the human organism, to a remedy, unless we keep this process in mind. This is the only way which will lead to the realization that the distribution of substances in the cosmos is quite different from what is usually thought. It is a striking fact—a fact to which no thought has been given for five or six centuries—that while certain analytical processes prove the existence of iron in the human organism (it can be said quite certainly that there is iron in the blood), attempts to prove the existence of lead in the human organism will fail, if the organism is in a normal state. Lead is only known in the form of lead ores, or heavy lumps. But just think of it—all metals which exist in the coarse, lumpy form as earthly substances were once present during the epochs of Saturn, Sun and Moon, in the fluid condition, even in the condition of warmth ether. Now, the human being—in a different form of course—was already in existence on Old Saturn. He has been involved in all these processes, among them the process whereby, out of a fluid, delicate etheric condition, iron has become what it is today. Man has been involved in the whole process of the world's evolution.

The strange thing is that the human being has taken iron and also magnesium into his own structure, but not lead. He has united the magnesium process with his own being. But he threw out the lead process. So far as the magnesium is concerned, therefore, we see that there are working, within the human being, the same forces as are working in magnesium in the external world; the human being has to master them inwardly. But before man was enclosed in his skin, when he was still a structure that was involved in a process of metamorphosis and united with the cosmos, he overcame the lead process and still has within him the forces for the elimination of the lead process. He has within him the up-building forces of magnesium and the forces for the elimination of the lead process.

What does this mean, in reality? You need only study what happens to the human organism in lead poisoning. It becomes inwardly brittle, sclerotic. It is therefore correct to say that the organism cannot tolerate lead and when there is lead poisoning there is lead within the organism. The organism begins to fight against the process that is contained in the lead substance—substances are always processes. Lead spreads out within the organic process, and the organism, exerting itself in opposition, tries to drive out the lead. When it succeeds it gets well. If the lead proves itself to be the stronger, the organism does not get well, and the well-known process of decay that is connected with lead poisoning sets in, because the organism can only tolerate those processes which overcome the lead process. It cannot tolerate the formative forces of lead. If we now try to find out what it means to the human being that he will not put up with having lead in his organism, we are led to the following: man is a being of sense. He perceives things around him and then thinks about them. He needs both forms of activity. He must perceive things in order that he may be connected with the world; he must also think about them. He must repress the act of actual perception and then unfold his own, independent activity. If we were only to perceive, we should lose ourselves all the time in acts of external seeing. But by retreating from the things themselves, by thinking about them—thereby, we become a personality, an individuality. We do not lose ourselves in the things. If we study the human etheric body, we find that it has within it a center for the forces which throw out lead. This center, approximately, lies where the hairs grow in a kind of vortex at the back of the crown of the head. That is the center of the forces which overcome lead. They stream into all parts of the organism in order that the formative forces of lead may not get into the organism. The forces which the body has developed for the overcoming of lead have great significance, for they are the same forces which enable me, when I am looking, say, at this piece of chalk, not to be entirely caught up in the simple act of looking at the chalk. Otherwise I should identify myself with the object of perception. But I make myself independent, I dampen down the perception of the object observed by means of those forces which overcome lead. It is due to these forces that the human being can be a self-contained personality; these forces enable the human being to separate himself from the world.

I will now speak of something that is very striking in connection with the forces which overcome lead. Not only have they a physical-etheric significance but also a psychical and moral significance.

The human being takes certain metallic substances into himself, unites them with his own bodily organism; other metallic substances he overcomes and has them within him only in the form of processes of rejection, processes which are master of these substances. Now why is it that in the course of his long evolution from the Saturn period and the Sun period, man has separated off certain external substances and has received others into his organism? In that man has this process of elimination within, he is able to receive into himself independent moral forces. We can imagine that the human organism, as constituted presently, may be unable to make use of lead but contains certain forces which compensate for lead; we can imagine the organism containing lead in the same way as it now contains iron. If this were so the human being would bring into himself semi-moral qualities; for it is so with lead. He would then have a morbid affinity (we should call it a 'morbid' or pathological affinity) to the impurities existing in the outside world. Such a person would always be on the lookout for vile-smelling substances and like to smell them. If we notice that some child has perverted instincts of this kind—and there are children who are partial to everything that smells,—they will sniff petroleum, for instance—then we may be sure that the quality of the blood that rejects lead is not present. And it is then a matter of calling up this lead-rejecting power by clinical methods or even by medicaments. It is possible to do this.

And now let us think of magnesium, a substance which plays a significant role in the human organism. There is something very interesting about magnesium. When speaking about education I have said many times that the first period of life, the period which lasts to the time of the change of teeth, must be sharply differentiated from the following periods. The second period lasts from the change of teeth until puberty. Magnesium, as well as fluorine, is necessary for the development of the teeth. But the process of the development of the teeth is not localized in the upper and lower jaws—the whole organism participates in it. The magnesium process takes place over the whole organism. And this is the most important process of all up to the time of the change of teeth. After the teeth have changed, magnesium has no longer its former significance. For the magnesium forces in the human being harden the organism; they enclose it in itself. This consolidation of the organism, this incorporation of the forces and substances, comes to an end at the second dentition.

Until then, the magnesium forces are exceedingly important for the organism. This organism, so far as its development is concerned, must now be considered a self-contained whole. It must contain and it must enfold the magnesium process, for if this process were absent the organism would lack the necessary forces of consolidation. The organism cannot cease generating the magnesium forces. This goes on after the change of teeth just as it did before. The magnesium forces must be worked upon in the organism, and after the change of teeth the essential thing in regard to magnesium is that it must be overcome, must be thrown out. It enters particularly into the secretion of milk, is excreted with the milk. The secretion of milk is connected with puberty, so you have here a periodic process. Up to the change of teeth magnesium is consumed, as it were, by the organism; after the change of teeth, up to the time of puberty, it is thrown off, separated. And magnesium, now a substance to be secreted, is one of the forces which form the milk. After puberty there is a kind of rebound and the magnesium forces are used for the more delicate consolidation of the muscles.

Substances are only a combination of processes. Lead is only in semblance the heavy, gray substance—with which we are familiar. It is nonsense to say that lead is a piece of coarse substance. In reality, lead is the process that goes on within the boundaries which mark the extent of the spread of lead. Everything is a process. One cannot say, once and for all, that certain 'substance processes' are worked up in the human being, and certain others, like the lead process, for which we must always have the power of elimination, are thrown off. It is not correct to say this because there are other processes, like the magnesium process, in connection with which there is rhythmic alternation; in periods which alternate rhythmically we have to consume the magnesium process, and then again throw it out.

This will show you that it means nothing to say, as the result of mere analysis: the human organism contains magnesium. It means nothing, for in the twelfth year of life these substances have quite a different significance than they have in the fourth or fifth year of life. We unfold a real knowledge of the human being when we know the period during which certain substance processes are important in the human organism. If we want to know how substances outside in nature can work further within the human organism, it is of very little importance to study the chemical composition of these substances. We must study something that is hardly studied at all today. If we trace back the study of substances to the thirteen or fourteenth century, we find the beginnings of modern chemistry. These beginnings are to be found in the alchemical processes which are so often scoffed at nowadays. But alchemy contained something else too, of which there has been no continuation. It is what might be called today the doctrine of signatures. This Doctrine of Signatures was applied especially in the study of plants but also of minerals, and it has not been developed or continued.

The characteristic quality of antimony is its well-known spiky, crystalline formation. If you apply a certain metallurgical treatment to antimony, you get the familiar “antimony mirror” when the volatilizing antimony is precipitated on a cold surface. Antimony has the tendency to develop forms which reveal themselves very clearly as forms of the etheric body. The shapes taken by antimony are very similar to the forms of certain simple plants which have an affinity to the etheric body. When one studies antimony one has the feeling at once that this antimony is very sensitive to etheric forces. It has an affinity with etheric forces. Everyone can confirm this by bringing antimony to the cathode. There will be a series of slight explosions which show the relation of antimony to the etheric forces. This is a striking case, but at one time people had a great faculty for understanding these things. This faculty is now quite lost and no attention or respect is paid to such indications as I have given. And for this reason, certain significant observations leave people in complete perplexity.

Think of diamond, graphite, anthracite, common coal. They are all carbon, but yet so different from each other. Why are they different? If people were capable of not limiting their investigations to the chemical composition but of finding out about the ‘Signature’, as it was called in olden times, they would begin to understand what the difference is between common coal and graphite. Common coal came into being during the Earth evolution, graphite during the preceding Moon evolution. Diamond came into being during the Sun evolution. When you study these things in the cosmic aspect, you realize once again that what is of essential importance is not the substance itself but the conditions and times under which and during which a substance assumed a definite form. Physical reality is subject to the element of time, and time has a definite significance. If you think of what I have said, you will realize: common coal is a child, it has as yet no great age; graphite is a youth, but older than common coal; diamond, though not exactly ancient, is very mature. If you have to set a task which demands the power of maturity, you will not give it to a child. Everything depends on the age. So you will realize that simply because of its cosmic age, coal, in whatever form it appears, has a different task from graphite which is more mature.

Insight into cosmic processes is necessary if we want to understand the relationship of the human being to what is out there in the cosmos. Antimony has a particular connection with the human etheric body, and if you introduce it into the human organism as a medicament, you must understand what antimony is outside the human being before you can know what is stimulated in the etheric body by the use of antimony. You must study the delicate processes in nature if you want to understand how a medicament is to act within the human organism.

In the three previous lectures I have tried to give you an outline of the kind of knowledge that should serve as a foundation for physicians. Owing to the very brief time at our disposal, it has only been the merest sketch. But you will have realized that to speak in detail would need considerable time. The kind of knowledge I have given as a foundation for medicine would constitute, as it were, a first course which would take at least a year and longer still if that were possible. It is impossible for me to do more than give a general description of these things, so I should like you to regard what I have said in the three previous lectures as a sketch of what a physician ought to have as a basis. Let me call it the exoteric side of medical knowledge, and it ought really to be followed by the esoteric side, of which we will speak now.

This esoteric side must be built upon the foundation of the exoteric knowledge. In your medical studies you must not be too proud to master the exoteric side; you must master this with all earnestness. It is difficult at the present time, but, as we shall see, much will be achieved in this direction by the establishment of the Medical Section here at Dornach.

After all, it is possible now to expand the short sketch that has been given by many details contained in my lecture courses and writings. Up to now, very little has been done in this direction and the work will only begin to develop in the real sense of anthroposophical medicine when this work that I am preparing with the help of Frau Dr. Wegman comes to the fore. It will then be apparent that Anthroposophy can give a great stimulus to medicine and medical studies. But you must realize quite clearly that medicine is a very special kind of study, with definite preliminary requirements—a study in which the results of Spiritual Science simply cannot be ignored. There can be no true medicine without the knowledge that results from Spiritual Science. The chaotic conditions prevailing today are due to the fact that the current trend of study and knowledge is utterly unsuited to medicine. We have a science of nature that has found its way even into theology, a science that is suited only to technical purposes and not at all to a real knowledge of the being of man. This science is not able to impart a true knowledge of man's nature. Medical science in the real sense demands something quite special and you will realize that this is so when I come to speak of how the human being really comes into existence.

I spoke yesterday from the exoteric side and will now make the transition to the esoteric aspect: external substances are, in reality, processes. Salt is only a precipitation of processes; the magnesium process, the iron process are processes which exist outside in nature. The lead and mercury processes are processes in external nature which the human being cannot have within his physical organism. For all that, it is only in outward semblance that these processes are not within the human being.

How does the human being come into existence? The physical germ comes into being through fertilization and there must be a union between this physical germ and the etheric body of the human being. But fertilization does not create the etheric body. The etheric body forms around what are, later on, ego organization and astral organization, in order to receive the being of spirit and soul who comes down from the spiritual worlds, the being who has been living in pre-earthly existence. The real kernel of man is of the spirit and soul. It has come firstly, from earlier incarnations, secondly, from the period between death and rebirth, and has been in existence long before any fertilization takes place. This kernel of spirit and soul exists before a connection is made with the physical germ cell which is the result of fertilization. It unites, first, with the etheric body which in turn unites with the physical embryo. Ego, astral organization, etheric organization—this trinity unites with what comes into being through the physical fertilization. You must regard the etheric body as something that is built in from out of the cosmos. Now at the time when the etheric body first unites with the physical organization it contains within itself the forces which are not suitable for the physical organization, namely, the lead forces, the tin forces and so on. It is only in semblance that the human being is not a complete microcosm because certain substances are not within him physically. The substances that are not contained in the physical organism of man are of the greatest importance for the constitution of the etheric body, and in the etheric body, before it unites with the physical body, there are lead processes, tin processes, mercury processes, and so on.

And now the etheric body (and the other members, too, of course) unite with the physical body. All the forces derived by the etheric body from the substances that are not contained within the physical body now pass over to the astral body—this happens to a slight degree during the embryonic period but in a high degree when the real breathing begins at birth. The etheric body then takes on those forces which the physical body works up within itself. Thus the etheric body passes through a very significant metamorphosis. It takes on the content and constitution of the physical body and gives over to the astral body its own constitution, its relationship with the environment of the human being. The astral body is now inwardly linked with what the human being is capable of knowing, and the moment you begin, my dear friends, to acquire not merely a theoretical but a true and inwardly digested medical knowledge—in that moment you make alive within you the knowledge that is already within the astral body. It is there, but it remains unconscious, and it is, in reality, a knowledge of man's relationship with his environment.

Let me take a special case. Think of some district that is depressing—on account of the soil containing gneiss and the mineral known to you as mica. Mica has a very strong influence on the physical constitution of a person who is born in such a district. The physical body is different in a district where there is much mica. The mica forces work upon the physical body from out of the soil. Now you will find that many rhododendrons grow in districts where the soil contains a great deal of mica. This plant grows plentifully in the Alps and in Siberia and so forth. The rhododendron substance is something that is intimately connected with the etheric body before it comes down into the physical body in such regions. This relationship with the rhododendron the ether body gives over to the astral body. And now, suppose that illnesses occur which are due to a preponderating working of the mica by way of the ground water. The etheric body has given over what came to it from the rhododendron, to the astral body. This element is present externally, in the rhododendron plants. This indicates that the rhododendron contains a sap that has a remedial effect upon this illness. In many cases, though not in all, a specific remedy is to be found in regions where particular illnesses occur.

And now suppose you are a physician. Every night when you go to sleep, you pass, in your astral body, into the environment which was once connected with the etheric body but is now connected with the astral body. If you have medical knowledge, if you know what healing forces exist in the environment, that knowledge becomes experience during sleep, and so you have continually the confirmation of what you learn, externally, through dialectics. And this factor must be reckoned with in medical study, because no outer dialectic learning of medical science really helps. It becomes fragmentary and chaotic if there cannot arise during every sleep, within the span of the astral body, the confirmation that is necessary. If medical knowledge is not acquired in such a way that the astral body, in the intercourse with the environment, is able to say “Yes” to what the student has learned, it is just as if he were listening to something that he cannot understand and only confuses him. So you see, medical knowledge is intimately connected with the sleeping state.

Such things convince us that medical knowledge must be acquired by the whole man, by man as a living, feeling being, for together with this ‘nightly’ intercourse with the healing substances, something else grows up, something that can never be acquired through dialectic—I mean, the true desire to help. Without the sincere desire to heal, the feeling of sympathy on the part of the physician with the person he has to cure, without this strong desire to give personal help, no healing in the real sense is possible.

And here I must say something that may seem very strange and paradoxical, but as you want to know in what way things are wrong today and what ought to be done, I must say it, for in Dornach we are working from esoteric impulses. People have often said to me that steps might have to be taken to protect the remedies that are prepared in our pharmaceutical laboratory, so that they shall not be copied by other people. I once replied that I was not so very anxious about this, provided we succeeded in bringing true esoteric impulses into our medical work. Then people will realize that the remedies are made with an esoteric background, and that it is not the same if the remedies are made here, with the esoteric life behind the work, or whether some factory copies them. This may seem very strange, but it is true nevertheless. Much more important than protecting things by business devices is the growth of an attitude which aims at making the remedies effective from out of the Spiritual. This is not superstition—it is something that can be substantiated in Spiritual Science. Therefore, people possessed of understanding will begin to realize that with the taking of remedies that are produced here, a beginning has been made in the right direction.

Such objections as have been made to me are due to the fact that people do not realize in the least how seriously the esoteric, spiritual life must be taken, above all, in medicine. If you once grasp this, you see that a center for medicine must be instituted here as a reality, not as a mere formality.

And now you will understand that a first, exoteric course of medical study should be followed by a second which approaches the human being esoterically, which merges medical knowledge into what becomes a true medical consciousness, a true medical attitude. There have, of course, always been individuals who sought instinctively for this. And in the last third of the nineteenth century, at a time when there was so little that was capable of producing this attitude, one could see, but only in isolated individuals who were then regarded as cranks, sporadic manifestations of this medical consciousness. The basis of the reputation enjoyed by the Viennese School of Medicine at the time when I was growing up was connected with its attitude to therapy, where the actual therapy hardly mattered at all, especially treatment of pneumonia, an illness where one can do very little for the central disease itself. You have all heard of medical nihilism, and this is its origin. The most eminent physicians in Vienna were deliberate advocates of medical nihilism In other words, they held the point of view that no remedy heals. To a certain extent, Rudolf Virchow (1821–1902), too, held this view. His view was: If a hundred patients are said to have been cured, one can assume with fifty percent of them that it did not matter whether they had been given a remedy or not; they would have got well without it; with 30 percent it could be said that the remedy had done actual harm; and with the remainder, chance might have brought it about that the remedy selected had helped. It is not I who make this statement, but Virchow, who had a great reputation in the medical world last century. I know eminent men today, too, who adhere to this view, although they may be advocates of therapy. No true medical consciousness is expressed in this view. Medical consciousness can never be regarded as a merely formal attitude. It must be a reality. Therefore, the second medical course would have to contain the human aspect that is built up on the basis of the exoteric material. There must be that human factor that worked, in a somewhat degenerate form, but, for all that so magnificently and attractively, in a person like Paracelsus.

Certainly, objections to Paracelsus can be made in certain details, but this medical consciousness lived in him, in a splendid way. Whenever he came to a district where the soil was strikingly red, he knew that a number of diseases—especially those that are due to diseases of the blood—were caused by the red sandstone in the soil. {Translator's note: The word in the German is the name of a substance described as a system of sandstone, shale and conglomerates of the lower terrain of Germany.}

The way in which a process of illness develops is very characteristic. We find that the people living in a district where there is this red sandstone soil have accustomed themselves to this soil and have a certain characteristic temperament. They have a very lively activity of the spleen. Coming as a stranger to the district, one does not easily take a liking to them. They are frightfully stubborn, dogmatic, obstinate, and when one considers what they do to be foolish—they just return the ‘compliment!’ But suppose a stranger comes and wants to set up a business or something of the kind. He cannot stand the soil, especially not the water, and he will show certain symptoms of illness. Paracelsus said that illnesses which are contracted in such a district are then passed on to the natives who are born there. He said that something must be present in the etheric body (which he calls the ‘Archaeus’). He said that the ‘Archaeus’ must have undergone something before it entered the embryo. Now in these districts we always find that laburnums are prevalent and in the blossoms, leaves and sometimes also in the roots of the laburnum there is a fluid which can provide a very useful remedy.

What is important is to unfold a quite different perception of nature through this medical consciousness. In my young days I knew a physician whom one often met in the meadows and fields—among the plants and insects and flowers. In the place where he carried on an unpretentious practice, there were three or four very learned men. But the work of this unpretentious physician who had such a love for the wildflowers in the meadows was much more fruitful for the sick people than that of the city physician and the other learned men. Their wisdom came from the schools, but his wisdom and understanding of remedies came from that direct intercourse with nature which leads to a real medical knowledge when we can love nature, in all her details. To look at fragments of nature under the microscope is not to love her. We must love nature. We must all be able to expand her to the macrocosmic. This shows you how necessary it is to call up this subconscious life of the astral body, particularly for medical knowledge, to call it up in reality.

It is not at all my wish to revive the stock-in-trade of ancient medicine, my dear friends, but only to lay before you the results of present-day observation. One is obliged to resort to the terminology of ancient tradition, because neither modern language nor modern medical terminology contain the right expressions. It might even be more favorable for the spreading of our views if we were to devise an altogether new terminology. But that would take years, and as you want to hear about these things now, I shall have to use the old expressions with certain modifications.

It will be a good thing to look, first of all, at the plant world—not because I want to recommend plant remedies for everything, but because much can be learned from the plants, above all for an esoteric deepening.

It is very important to study three things connected with medical tradition, but not to study them in the way that is current in present-day science. When a student has learned something of today, he knows it and he thinks: Well, that's all right, I know it and I can apply it. But a religiously-minded person learns the Lord's Prayer. He, too, knows it, but he does not think that the mere fact of knowing it is sufficient. He says it every day as a prayer. What he knows, he prays, every day. He lets what he knows pass through his soul every day, and that is a very different matter—very different, indeed.

Or think of an Initiate. We presuppose that he knows the elements of occult science. He himself attaches no importance to the mere fact of knowing them, to the fact that he once assimilated them. He knows that it is much more important to let the very first rudiments and then all that follows flow through his soul from time to time so that his soul can always be receiving new forces of inspiration. A person who is fundamentally religious has quite different experiences from one who merely regards nature as something that is there before us in the physical world. We must live in the rhythms of nature again and again if we desire a living and not a dead kind of knowledge. There must be constant, rhythmic repetition of knowledge and the activity of knowledge. That is what I mean when I say that a real medical consciousness must be the basis for medical science. The acquisition of medical knowledge from the nature of the human being and from his environment—that is what is so important, in therapy as well. Again and again you must let the plants really come to life in the soul.

Three things are of particular significance in the plant. One is the scent that is connected with the oils. The scent, or aromatic element is that which attracts certain elementary spirits who like to come down into plants. The activity (not the substance) which underlies this aromatic nature, is to be found, in its most concentrated form, in the mineral kingdom, in sulfur. This spiritual extract that is active in the aroma of the plants gives rise to a kind of longing in the elementary beings who come down through the scent. In ancient medicine, this element was known as the sulfuric nature of the plants. If we contemplate the sulfuric nature of the plants we can acquire an understanding for their scent, if we know that something spiritual is in play above and below when the plant gives off its scent. That is the first thing.

A second thing that we acquire is an inner feeling-filled understanding of what is growing in the leaf. The form and character of leaves is so manifold; they may be serrated, with pointed or round ends, geniculated, and so forth. We should evolve a delicate perception of this leaf nature of the plants. For those spiritual beings who come down through the scent can draw life from this leaf nature. And streaming from the cosmic periphery inwards, there is everywhere the striving to the drop formation. This can give you a marvelous feeling for the cosmic, form-loving principle that is contained in the leaf. And then, think of the plant covered with glistening drops of dew in the morning. In their essential nature these drops of dew are a reflection of the striving of the cosmic periphery to produce the spherical form, the drop form in the plant kingdom. The principle of drop formation is at the basis of the leaf nature in the plant. If the peripheric, cosmic forces alone were spiritually active in the plant, it would always produce this spherical form. The spherical formation is particularly to the fore when the cosmic forces get the upper hand in the formation of berries, also in the formation of many leaves, but the drop formation here is immediately taken possession of by the earthly forces, and manifold forms arise.

This striving towards drop formation is concentrated, in the mineral world, in quicksilver. Therefore, ancient medicine called this 'striving towards drop formation', the Mercurial principle. In ancient medicine, Mercury was not the substance of quicksilver but the dynamic striving towards the drop formation.

On the earth, quicksilver is the metal which has the drop form because the conditions for this exist. On the earth, quicksilver has the form which silver has on the moon, where it would also have to exist in the drop form. The point is that ancient medicine called everything that had the drop form Mercury. All metals were also 'Mercury' in ancient medicine. This ancient medicine had living, mobile concepts, and we, too, must develop them. We must gradually grow into a frame of mind which makes us say: “When I walk over the fields in the morning and see the silver pearls of dew on the leaves, these pearls of dew reveal to me what is living spiritually in the leaves themselves; it is the striving towards the cosmic form of the sphere.” But this must become a feeling within us, so that we are able to understand the plants. We must understand them in their cosmic, spherical form.

If you get such an insight into the nature of the plants that you understand the forces in them which are striving towards drop formation, and then again think of their scent, you will gradually begin to understand everything that works centrifugally in the human being. There is a centrifugal force at work when the nails are cut. The centrifugal forces working through the human being make the nails grow again. During the first seven years of life particularly, the forces which come to a conclusion with the second dentition, work out centrifugally through the human being. They express themselves strongly in the formation of sweat. The element which in the scent of plants strives upwards and attracts the Nature Spirits is also active in the smell of sweat which works in the centrifugal direction. And so if you want to look for the plant nature in the human being, you must seek it where it strives outwards, and in this way you unfold an intimate knowledge of the connection between what is outside and what is within the human being. For you see, when the etheric body gives over its special features to the astral body, the whole thing is changed. The inclination of the etheric body would be to unfold what it takes from the environment, in the upward direction; inasmuch as this is given over to the astral body, it unfolds in the centrifugal direction. In this respect, too, the human being bears the plant existence within him.

And now think of how the plant sinks into the earth with its root; how with its root it enters into a close connection with the salts in the soil. A process takes place here that is exactly the opposite of the one we know in the material world. Take sodium chloride which, in solution, tastes salty, and now think of the process being exactly reversed, the solution being arrested, a congealment taking place and the smell and the taste become latent. There you have the process which goes on between the soil and the root of a plant. That is what was known as the salt process in ancient medicine. Ancient medicine did not use the word salt in the way we use it today, but meant by salt that element which, in the downward-pointed root of the plant, enters into a connection with the substances of the earth. That is the salt nature.

By directing your attention rhythmically to these wonderful secrets of nature you fill your medical knowledge with life that is capable of practical application. If you try in this way to fill your medical knowledge with life, you will begin to regard nature and the human being in such a way that the capacity to heal will be born of the strong impulse to give help, of which I have spoken. The capacity to heal can only come from this foundation. It must be quickened by keen, diligent, and zealous exoteric learning, for otherwise mere vagueness will be the result. But it is necessary to know that the real foundation of medical knowledge lies in this rhythmic, meditative absorption in the natural environment of the human being, and not in theoretical study.

What I am now going to write on the blackboard is not there in order that you may “learn” it, but in order that it may quicken life in your medical thinking.

You healing Spirits,
You unite
With Sulfur's blessing
In the ethereal fragrance;

You come to life
In upward springing Mercury
Dewdrop
Of growing
And becoming.

You make your halting place
In the Earth Salt
Which nourishes the root
In the soil.

Ihr heilenden Geister
Ihr verbindet euch
Dem Sulphursegen
Des Ätherduftes;

Ihr belebet euch
Im Aufstreben Merkurs
Dem Tautropfen
Des Wachsenden
Des Werdenden.

Ihr machet Halt
In dem Erdensalze
Das die Wurzel
Im Boden ernährt.

This is what the soul receives in looking out into the universe around. The human being answers:

I will unite
The Knowledge of my Soul
With Fire of the flower's fragrance;

I will bestir
The Life of my Soul
On the glistening drop of leafy morning;

I will make strong
The Being of my Soul
With the all hardening Salt
Whereby the Earth with loving care
Nurtures the root.


Ich will mein Seelenwissen
Verbinden dem Feuer
Des Blütenduftes;

Ich will mein Seelenleben
Erregen am glitzernden Tropfen
Des Blättermorgens;

Ich will mein Seelensein
Erstarken an dem Salzerhärtenden
Mit dem die Erde
Sorgsam die Wurzel pflegt.

If over and over again, as the pious are wont to do in prayer, we make this inwardly living, it will quicken in the soul the forces which render us capable of medical work. The ordinary powers that are educated in the schools cannot awaken true medical knowledge, for true medical knowledge must be drawn forth from the soul. And so at the very summit of the esoteric studies which we are to pursue, I always place this thought: that the powers of the soul must first be quickened in order to bring to birth in the soul the faculty that can lead to true medical knowledge.

I have now studied your questions, which are all connected with the matters of which we spoke yesterday. A first category of questions has arisen out of a certain uneasiness. Single questions will find their answer in the course of the lectures: in the case of others which are fundamentally similar, it will not be possible to give theoretical answers—the answers will only emerge as a result of the whole course of lectures. Fundamentally, the trend of all these questions is: How can those who are attending this course develop their medical work in association with Dornach? The true development of the impulse of which I spoke in the esoteric sense yesterday and shall speak of again tomorrow—this true and real development of our work is the foundation of everything, although, naturally, such matters can only be inadequately dealt with in so few lectures. To begin with, I will make certain general remarks in connection with what was said yesterday.

Little is accomplished, my dear friends, if we simply direct a person's general attention, or if he does this himself, from the material world to the spiritual world. In every sphere of life—and most strongly of all in the medical sphere and for the physician—this general indication towards the spiritual does correspond with an innermost need of the soul. But in many respects this need requires much greater definition and clarity and also possibly most important of all—a greater inner strength than that with which it usually arises. It is a striving in you, my dear friends, but a definite path must be taken. The impulse towards this path can, in the first place, be given by me, but having received this impulse you yourselves must continue to work in association with Dornach—definitely those of you who have set yourselves this task.

It is not enough to strive, in a general way, towards the spiritual; this striving towards the spiritual must be concrete and real in every domain of life. We must enter into a real communion with the being of the world, with the being and reality of the external cosmos. Man has no experience of the cosmos today and because he does not experience the cosmos, he does not experience spirituality, for spirituality can only be acquired by way of the cosmos. In its external form, medical science yields no spiritual knowledge concerning existence. It is only by being able to place things in their whole cosmic connection that we learn to see through the veil of nature to the spiritual forces behind her.

For more than twenty years now within the Anthroposophical movement, it has been possible to study and to get a very exact knowledge of the difficulties that may arise in the pursuit of the spiritual life. And it may sound rather trivial when one describes, in a few brief words, in what these difficulties have consisted. They have consisted simply in the fact that those who were striving for esotericism in some domain or other wished to make things too easy, too comfortable for themselves. The esoteric path is either difficult or it is no path at all! Esoteric development is not to be obtained along an easy or comfortable path. We must take in complete and solemn earnestness the general and often repeated statement that it is a matter of overcoming difficulties, of man growing out of and beyond himself. From now onwards, from the time that began with our Dornach Christmas Foundation Meeting, a kind of change must take place in our whole conception of the anthroposophical movement. This change must also take place in the individual sections of the work. And you who are seeking to find your path in the medical sphere, must, from the very beginning, share in this essential change. There can be no question of regarding the esoteric path as a mere adjunct to life; one's path of life must be completely filled with esoteric impulses. The help that can be given will be given in the lectures. But, as I shall say at the end of this lecture, something else must be added as well.

Let us first consider one particular detail. For if you have not the will to enter into details in spiritual studies, you will not be able to find the way to the spiritual. Let it not be imagined that one can really find the spiritual as a dreamer, or as a person who gives himself up to all kinds of vague inspirations and the like. The spiritual must be attained today by the most intensely earnest, inner striving. And it can only be attained through the knowledge that comes from the spiritual world.

I have already said that much can be learned from the world of the plants. And now let us think of a plant. People study plants today by looking at the root, stem, leaves, flowers, pistil, stamens, seed. The seed develops in the ovary, and then people describe what they thus see in the plant more or less as they would describe an armchair, adding that they often sit in one! This, more or less, is the way in which a plant is described. We are told how the roots are set in the soil, how they draw in physical and chemical forces and substances, how the saps rise up through capillary action, or the like. To speak of a spiral arrangement of the leaves is considered an error, an aberration. At any rate, it is not known that this spiral arrangement is connected with the cosmos. So far as the blossoms and flowers are concerned, the most that can be said is that botanists picture some kind of force in connection with the colors and substances of the flowers, or with fertilization. The whole thing is described entirely from the external point of view, just as one describes how a person sits in an armchair. Yes, but the reality that must be grasped simply cannot be grasped by these methods. In studying a plant we must realize that a wonderful mystery is indicated as it stands there with its root sunk in the soil. The stem with the leaves points to another mystery and the processes in the blossom to yet another mystery.

Think of it, my dear friends—the root, sinking into the soil, represents the end of the plant existence in the direction of the solid earth. But this root could receive nothing from the soil if the soil of the earth had not first come under the influence of the cosmic environment. The cosmic environment, not only the warmth and light of the sun but also those forces which proceed from the rest of the planetary system belonging to the earth, influence the earth from the surface a little way inwards. And the forces that are quickened in this way in the earth's substances make it possible for the root to be within the earth.

Now in the human head we find the same forces that play around the roots of plants, but in the human head we find them in quite a different form from that in which they exist around the roots of plants in the soil. Inner perception of these things will never unfold if we go no further than what can be learned today from natural science. Many of your questions speak of this as the chaotic knowledge given you by contemporary natural science. What is necessary is to understand, out of real experience, the nature of what was once called the earthy, the watery, the airy, the fiery. For if you simply go on speaking about hydrogen, oxygen, carbon, nitrogen, sulfur, phosphorus, in the way modern chemistry speaks, these things will always remain something quite external. You will never be able to think in any other way than that you stand there as a human being and somewhere outside there is oxygen or nitrogen. What modern physiology or chemistry tells you about oxygen or nitrogen is something quite direct. Physiology tells you that nitrogen exists in the organism, but you do not experience nitrogen in the organism. What is necessary is to take one's start from what can be experienced. And things that can be experienced must be deeply united with our whole being, if it is our aim to place ourselves in the service of the shaping of the world. And that is what we are doing when we heal.

Now so far as one of the elements of antiquity is concerned, everyone can know that he experiences it. This element is warmth, warmth as a quality of nature. We experience warmth, for we feel warm, or we feel cold. We are not as external to warmth as we are to oxygen and nitrogen.

It was characteristic of ancient study of nature that it took as its fundamental element something that could actually be experienced, something in which a man can be, not something that he must remain outside of. Let us first take this element of warmth, of fire, because here it is easiest to grasp the factor of actual experience. We know that as human beings we experience warmth. Now what is, for the plant, the earth—the earthy element is, for the human head, warmth.

Suppose you have here the earth, and 'think away' from it what appears to you as the earthy element; also think away the fluid and the airy, but let the warmth remain, so that you have a kind of ‘soil’ of warmth. You can picture this quite easily. Now take the whole thing (See Illustration I on the next page) and turn it round, so that what was formerly below is now above (See Illustration I on the next page)—it is a polar opposite.

You can now say: I behold the root of the plant, it is within the earthy soil; I behold the human head, it is in the 'warmth' soil, but the soil is in the reverse position. That is because what happens here (See Illustration I on the next page) lies four stages further back than this. (See Illustration I on the next page) If you speak of what goes on in the plant root as an earth happening, you must speak of what goes on in the human head, out of the warmth, as a Saturn happening. Between them are Sun and Moon happenings. And now 'think away' from the human head everything that came into it at later stages. Think away the earthy, the watery, the airy, and picture merely the warmth working in the human head, the warmth that provides the rest of the organism with differentiated warmth—and then you have the human head as it is today, a miniature Saturn. In the human head today you have the old Saturn organization. And if you understand the connection, then you say to yourselves: In the cosmos, untold millennia ago, there was a structure that anticipated everything that exists today as warmth in the human head. And the plant root in the earthy element today creates an image of the condition that thus preceded it.

There you have a connection. You behold ancient Saturn in the warmth organization of the human head. But if this act of beholding is to be true, it must be connected not merely with theoretical ideas but with inner, moral impulses. Looking at the human head must be an experience that moves us inwardly; we feel that the human head is the living, embodied remembrance of a very ancient evolutionary period of the cosmos, of the old Saturn period. Try, for once, to let this feeling permeate you. I am a human being who has reached a certain age. My childhood stands before me; the remembrance of childhood rises up. As one who has grown older, I sink myself into the remembrances of my childhood. This in itself gives rise to a certain inner experience which we can confront with moral power. And now expand this feeling to the point where you say to yourselves: “As a human being I was present during the old Saturn period. If, in this present time I understand my head truly, it is like a living remembrance of a primeval evolutionary period of the cosmos.” All that takes shape through the remembrances of childhood is infinitely multiplied when contemplation of the living head leads us back to the time of Old Saturn.

Such knowledge is only of value when it is steeped in moral feeling, when one can really be filled with awe by the fact that our own activity leads us into a real experience of the cosmos. Meditation, above all for the physician, does not consist in merely brooding over thoughts; meditation consists in actually bringing such interrelationships before the soul and having, in regard to them, manifold feelings through which one may experience all kinds of inner shocks and emotions. Suppose I meet a human being whom I have not seen for, say, forty years. As he comes before me in his present form, the picture of his childhood stands before my soul. I see him before me as a child. This gives rise to certain inner emotion or shock. I look at the root nature of the plant, I acquire the capacity to relate this root nature to the human head, and the human head leads me back to the time of Old Saturn. Meditation must penetrate to the very soul; it must quicken a deep inward life.

This is an indication of how, after the foundation has been laid by a course of exoteric study, everything in the esoteric domain must aim at promoting intuitive experience of the cosmos in connection with the whole being of man. For just as the Old Saturn existence can arise within you when you study the connection between the human head and the root of a plant, so too can the Old Sun existence arise within you when you study the connection between the human heart and the development of the stem and leaves of a plant. The stem and leaf development in the plant is, again, a remembrance that has now become living, of the Old Sun existence.

The flower in which the seed is produced is connected with the human metabolic system, the limb-metabolic system. And when we study what goes on in the flower in connection with the metabolic or limb system in man, a remembrance of the Old Moon period arises. And if you have this inner experience, if in deepest meditation you feel these connections inwardly, then you experience still more.

Something of great significance is experienced. If with this deepened feeling you turn your soul to the root of the plant, you will begin to feel as if no plant root were really still, but as if it were moving. You learn to recognize this movement. I can only give an outline of these things. I can only point to an impulse, to the way in which inner experience must be built up and how knowledge of nature becomes a real wisdom. You will experience this movement in the root of the plant. And contemplating it, you will feel as if, together with the root, you were moving through cosmic space. Through this very experience, in which you seem to be in the chariot which travels with you through the cosmos with the swiftness of the plant root, you will discover that what you are really experiencing is the movement of the planetary system through cosmic space. In the root of the plant you experience the movement of the whole planetary system through cosmic space. And if then, in the same way, you experience the growth of the leaves, again you experience a movement in which you yourselves participate. And this is the true movement, the inwardly experienced movement of the earth.

What the Copernican system has to say about the revolution of the earth around the sun is nothing but a series of constructions. The true movement of the earth becomes an

inner experience when we deepen ourselves in the connection which exists between stem and leaves. In your contemplation of stem and leaves you move, together with the earth, in the wake of the sun, so that the earth really seems to be doing what the Copernican system describes. But the movement is, in reality, a much more complicated one.

If you contemplate the processes in the blossom around the stamens and the pistil deeply enough, you will experience the movement which the moon carries out around the earth. In experiencing the flower you experience the movement of the moon—a movement that is already separate from the earth. The planetary system as a whole is experienced in the root of the plant, the earth's movement in the stem and leaves; the moon's movement which has been separated off, is experienced in the generation of the seed in the plant.

I say this to you, my dear friends, in the first place, in order that you may learn to have insight into things of which ordinary science takes no account at all, because it considers that such matters are neither knowable nor worth knowing. But they must be known—otherwise nothing of reality can be known. And I tell you all this for yet another reason. I do not think that, in the ordinary way, anybody gets a shock or feels emotion from what he learns about the plants. It causes him no inner concern—he simply assimilates it. And he experiences nothing at all, in reality. But in a second medical course such as that of which we spoke, if you begin to know the planets' movements, the earth's movement, the moon's movement from your contemplation of the plants, the minerals, (though here things are rather different) and also of the human being—then these things will not leave you indifferent.

It is essential for us today, my dear friends, to bring activity of knowledge into these things. The heart feels that these are the ways which knowledge should take. But what is offered to the heart is something that is merely didactic, containing nothing of the realities. People think they have the realities in what is nothing more than a tiny fragment.

What is the attitude of science today? It always seems to me to be rather like this—suppose someone were to go to Dresden and were looking at the Sistine Madonna. A scientist might come up to him and say: This Sistine Madonna is, after all, nothing but an external impression which comes to you from outside. Then he might proceed to take the Madonna out of the frame and break it up into fragments getting smaller and smaller until they were mere atoms. And then he might say: Now you have real knowledge of this Madonna. But this is all wrong. If we want to have a real understanding of the Sistine Madonna we must first be able to enter into the aims of religion, then into all that poured into this Madonna figure from Raphael's spirituality, then into many other things too, but this is the first: we must try to enter into the intentions of the Gods, of the Divine Spiritual Beings behind the physical world. This would have to form part of the second medical course of which I have spoken. Only in such ways is it possible to bring people near to reality.

If you will take what I have just said as a stimulus, you will understand the two meditations which will awaken the power of medical understanding within you. In this meditation you may proceed as follows: First of all you can deepen yourselves in contemplation of the external phenomenon of fire, of fire that gives warmth, realizing in this contemplation that this external manifestation of fire is Maya, semblance, illusion. Behind the fire there is something quite different. Behind the fire there is working, active will.

You may ask: Yes, but how do I get to know that there is active, working will behind the fire? All true esoteric instruction addresses itself to the powers in the pupils themselves. If you will allow what I have said today really to enter into your hearts, there will arise within you the realization that wherever there is fire, there, too, is active working will—just as when you see the form of a human countenance, a human figure, you realize that here there is spirit and soul. Wherever you have fire, even in the tiniest match, there is active, working will. In order that you may also be able to penetrate the other substances of nature, you must reach the point where a burning match is no longer merely the external phenomenon that would be described today, but where you actually see it as active, working will. When you are able in this way to transform your minds and hearts, you will find that your soul learns to experience quite differently, to have quite a different attitude to the environment in which you find yourselves. You will find that your own working, active will is akin to fire. You will live out into the world from your own inner being and you will have a much more subtle and delicate perception of fire than before, because you realize its kinship with your own will. You will find this kinship wherever there is fire. You must learn to realize: I am really within this fire, for it is active, working will; it belongs to me, just as my own finger belongs to me.

Air must be encouraged in you as courage. Wherever wind blows, you will experience it in your own soul as courage. What you see in outer nature as air—this is courage. Courage is air. This must be an experience in your soul.

Water is the outer manifestation of feeling. In feeling there is the same inner activity as is present in the external world, in water. Water is feeling.

Earth, solid earth, is the same as thought. In thought, life freezes.

If you can grasp these four points in meditation; if you can learn to think of fire as active, working will—if you can take the external appearance of fire as manifestations of this active will—if you see in the fire this active will just as you see spirit and soul in the form of a human being—if you can feel that the external form of the fire is maya—if you can feel that the blowing wind and the clouds are phenomena which are a revelation of courage—if you can see water as an expression of feeling, and the earth as something that resembles your own thoughts—then you will discover that this organic process, which arises in your own being as an earthly going out from the head and stretching downwards, is a continuation of the earth formation, the uniting of a substance of earth formation which has weight, and this is the nature of thought.

If you then pass to the breathing and feel how, in the breathing the aeriform nature of the human being is circulating, then you will recognize, in the activity of man's aeriform nature, everything that may be called activity in the human being, that takes him into the outer world, in order that he may assert himself within this outer world. And you will try to learn from the study of many phenomena in outer nature, what it is that happens to the air in the human being.

And you will know that the watery organism of man, the fluid organism with its inner mobility, is the seat of feeling, the feeling that flows in the centrifugal and centripetal directions. You will know that the movement of air is a semicircular movement, from above downwards. You will know that what lives in the fluid nature has a centrifugal and centripetal movement in man and strives everywhere to hold the balance.

Thus, from observation of what exists outside in nature, you will find the transition to what happens with these elements in the human being. The essential point is that we shall not rest content with observation of the ordinary kind, for this makes us earthy ourselves, dried up and rigid, and we lose our mobility.

Much has been given in what I have sketched today. Intermediary stages have been left out because it would take too long to give you every detail. I can only give suggestions. You will have realized from what I have said that the whole method, the whole way of medical study must become different. And now see to it that what I have told you here really bears fruit within you. Many of the questions which you have put with heavy hearts and which I have read with a heavy heart because they point so tellingly to what is needed in our times, will be answered if you always remain in connection with the Goetheanum. If you do this, your medical studies, wherever they may be, will constantly be enriched.

It is, of course, essential that you should realize the necessity of earnest striving, earnest learning. You must work seriously and earnestly. And you must have a second feeling which arises in you in all sincerity—you must decide whether you will follow this feeling, or whether you will not. This feeling must be that the enrichment of medical study is to proceed, in future, from Dornach; in Dornach we shall try to give the enrichment that is so needed today. You must choose the path you are going to take in medicine. For one thing, there will be the problem of karma. In the nature of things, those who want to heal must have an intimate understanding of karma in the world. I shall speak of this again. In healing, one cannot run counter to karma; one can only heal in accordance with karma. But where karma is concerned one cannot say superficially: When someone is ill, it is his karma to remain ill; and when he is well again, his karma has given him health. It is not right to speak thus. The question of how karma works in human life needs a real, fundamental deepening, a cosmic deepening. These things will be taken care of in Dornach for those who seek them.

I have already said that in the future, impulses will be given from esoteric sources, for account must be taken of the realities which exist and which were reckoned with in the foundation of the General Anthroposophical Society at the Christmas Meeting. As I said yesterday, the question of others copying the remedies causes me no anxiety, if in Dornach, it is really understood that esoteric medical study must be carried on in a much deeper connection with Dornach. To this end it will be necessary to carry out this medical work in the same way as other branches of the spiritual life in Dornach.

In the life of the Anthroposophical Society it was always the case that those who wanted to become esotericists did not pay enough heed to the inner conditions of the esoteric life. And so the years went by. It has only been in two spheres that we have been able to achieve what is necessary, namely, in the sphere of General Anthroposophy and in the sphere of Eurythmy and the Art of Speech. But the independent, inner activity that has developed in these spheres must be developed in all the Sections now to be formed. And to this end you must really submit to the conditions that will be made; you must submit to them in full confidence and trust.

One of these conditions is that I shall carry out everything connected with the medical sphere in association with Dr. Wegman, who in the course of years within the anthroposophical movement has prepared herself for medicine and whose place in this medical movement is such that it will be led by her in association with me. And so those who join Dr. Wegman with confidence will get help from Dornach as they go along. An arrangement will have to be made that those who want to remain permanently connected with the Section for the renewal of medicine shall address themselves, with their requests, to Dr. Wegman, in complete confidence.

Periodically—perhaps about every month—we will answer, in a circular letter, the questions of those who, at the end of this lecture course, want to become pupils at the Goetheanum. It will be the same in all the sections. This circular letter will answer the questions put by individuals and all those who are members of the corresponding section will receive the answers. But unless there is inner confidence, there will be no success. A real link will be created by these means, and all your human and medical needs will be satisfied.

This is how things will be arranged to begin with, until we can take further steps. The great failing that has existed in the esoteric life hitherto is that people have been arrogant enough to think that they should always receive their esoteric exercises from me. They all wanted to come to me, not to others. That is where the esotericism has foundered hitherto. For inner, occult reasons, the only possible way is for what lives in the well-spring of esotericism to be led and guided by the personalities who are suited for this work. This leadership by persons who are destined for it by fate—this is part of esotericism. It is a principle that has been rejected because people were immodest. If this principle is not adopted we shall not make progress, even in the newly founded Anthroposophical Society.

Thus I have sketched, and I will still further develop, how the true esotericism must work on into the future. Tomorrow I will try to answer the greater part of the questions which have been put and will all amount to this: How can I find my way into a training that has its center in Dornach? You will be able to find the way, but you must have confidence. It is not a matter of belief in authority but of an intelligent building upon an inner foundation, and an acceptance of conditions that are created by destiny.

For reasons I will not now mention, I will postpone the more esoteric lecture I had intended to give today, to the end of this course, and speak to you now about something else.

A certain amount of astonishment may have been caused when it was said yesterday that if we want to get at the realities, we must think, for instance, of thought being behind solid, earthy phenomena, and courage behind all that is of the nature of air. There is a significance from the point of view of medical history in having our attention drawn to the fact that thought is to be connected with all that is solid, earthy, all that stands before us with definite contours. For this leads us to say to ourselves that thought—thought as a force—is not to be connected with the watery, with the circulation of fluids in the human organism. Neither is thought to be connected with the airy and the warmth nature in man. We have spoken of the conception we must have of the air and the warmth in the cosmos. Within the human being, too, all these things are present, but in a particular form. Within the human being it is like this—only that which has contours, including that which, although it may be soft and pliable, has, nevertheless, the character of solidity, only this may be thought of as corresponding to thought. We have said that behind the fluid, or the watery element which confronts us in the physical world, we have to think of something spiritual—namely, something that is of the nature of feeling.

This element of feeling within the human organism must be thought of in a special way. We usually think of subjective feeling in this connection; we think of feeling that is connected with the psychical and bodily constitution of the human being. But within the human being, feeling is not merely this direct experience; feeling has an up-building activity within the human being. The watery or fluid body, as a formation of the universal, cosmic fluidity, contains feeling as its very essence. This etheric activity that works within the fluid body must be understood, but it cannot be understood by the same kind of knowledge that we apply to something that is outside the human being, because the substances and processes within the human organism do not work in the same way as they do in the external environment. The moment we come to the fluid organism—when we have to do with a part of the human organization which is in fluid circulation, although there are vascular organs within it—in that moment the knowledge forces which can be applied to what is outside the human being in the physical world are no longer adequate.

That is why medicine lost its knowledge of the fluid man—that was the last of the higher members of which knowledge was lost. One may say that up to the middle forties of the nineteenth century, medicine still had an inkling of the existence of this fluid man. People spoke of the humors, of the circulation of the fluids, of the mixture and the separation of the fluids. Medicine was not confined to the physiology and pathology of cells but actually perceived the combinations and separation of fluids. In the nineteenth century, of course, it was all tradition, but this tradition led back to the time before the fifteenth and sixteenth centuries, when men had not only tradition but also actual knowledge—knowledge in the form in which we today wrestle for in Anthroposophy and should be able to reach in imagination. Knowledge in those days had, it is true, an illusionary character, but men had instinctive imaginations. It was known that the human organism cannot be understood by mere sense perception and cogitation; it was known that thinking and sense observation could only be applied to those parts of the organism which have firm contours, and that knowledge of the circulation of the fluids in the watery man must be gained through imagination. It is, therefore, not to be wondered at that the perception of this fluid man was lost. Perception of the fluid man can only come again when we attain to imaginations in full consciousness.

Let us go over what has been said, once again. When the bony system is building itself up from out of the human organism taken as a totality, when the human being is, as it were, crystallizing into the skeleton—this is not a good way of expressing it, but you will understand what I mean—cosmic thoughts are weaving in him. The organs that have definite outlines have these outlines only because they are subject to the same forces to which the building of the bones is subject. It is only the bony structure in the physical sense that is of the nature of thought, and the other organs with definite outlines have been built up out of the etheric world by an activity of thought. Inasmuch as they have definite outlines and contours, an activity of the nature of thought has been working. The forms in the human organism of which physiology and pathology speak are the result of an activity that is of the nature of thought.

But this is only one member of the human organization, and it must fall out of the human organization if one does not rise to imagination. It is imagination that can lead us to the fluid man, to the way in which the muscles are formed out of the fluidity and how the being of man pours into the muscles. Muscles appear to be solid, but this is mere semblance.

Imagination is indispensable if one wants to comprehend the uniting of the solid nature of the bony structure with the fluid nature of the blood into what has the semblance of another solid structure—muscle.

We must therefore realize: Thought, which is of course, supported by physical perception, can in reality, only grasp the bony system, and apart from the bony system everything else that thought may say about the human being is fantasy.

We must ascend from thinking to imagination. With imagination we can grasp the nature of the fluid man and understand how this fluid man shoots into the muscular system. The fundamental nature of the muscles can only be grasped by imagination. Why is this? You see, if you apply thoughts, you cannot help applying, too, those laws which are discovered by thought, namely, mechanical laws. You apply the laws of statics and dynamics, and this is possible with the bony system. But just try to apply statics and dynamics to the muscular system and see how you get on! Try to calculate from the laws of statics how you can crush a cherry pit, or a peach pit, by biting it. Try to find out by an experiment how much weight of pressure is necessary to crush this cherry stone. Some—not all of us perhaps—try to bite them! But try to reckon out whether, according to the laws of mechanics, a muscle is capable of crushing a cherry pit. Thought alone will never help you to understand the muscular system. It is quite impossible. The moment we come to the muscles, the principles of mechanics become futile. We must be able to pass over to a form of knowledge that can leave the laws of mechanics behind and which grasps the whole picture of the muscles through imagination. Ordinary gravity is non-existent here. For the moment you come to the watery element you have to do with pure buoyancy.

In the things that you do with your etheric body, you have nothing to do with weight but with what overcomes weight to a great extent. Even this will make you realize that quite a different form of knowledge must be applied to the muscular system. This form of knowledge is imagination. The muscular system is comprehended through imagination—though there are transitions everywhere. It is not possible to understand the muscular system unless we conceive of it as a structure that has not arisen in the same way as the bony system. It has taken shape, as it were, through a coagulation of blood. This is just as inadequate an expression as when I say that the bony system crystallizes, but it is a comparatively correct picture. Suppose you take some bone—the radius or the ulna, or upper arm—and apply the laws of leverage to it. This is quite all right. But while you can understand by the laws of leverage and other laws of mechanics what goes on in the radius or upper arm, just think whether these laws help you to understand what is going on in a muscle. Your mental pictures here must all become mobile, must be transformed. The essential characteristic of imagination is that it can always yield and give way and so embrace the substance of things that have their being in the process of metamorphosis. And this is the characteristic of the muscle; the muscle has its life in its metamorphosis. In contrast to the bones to which the laws of mechanics can be applied, the muscle is just as mobile as the pictures of metamorphosis—say pictures, not thoughts—which we have in imagination.

In the bony system we have the solid, earthy man; in the muscular system we have the fluid man, the watery man.

At the stage of inspiration, above imagination, we come to the airy man, to what is aeriform within the human being. In inspiration we approach a mode of cognition that very much resembles the hearing of musical tones, melodies. Inspiration has nothing any longer to do with concepts but with something that is like the cognition, the realization of music. Music must not always be heard; inasmuch as it is spiritual, it can also be felt, experienced. All inspiration has, fundamentally, something musical about it. It is a strange fact that the form of the inner organs of man, of those organs which really provide for the growing organization during life in nourishment, breathing, etc., that none of these organ forms can be explained by any laws of mechanics. Not even by imaginative knowledge are they to be explained. It is just nonsense to try to explain the form of the lungs, of the liver, through their position, through the lie of the cells or through weight. Just try to discover if anyone has succeeded in explaining the form of the liver or the lung and you will find that there is nobody. For these organs, which look after the life that is coming into being during earthly life, are present, in germ, at a very early stage, although later on they are much metamorphosed. They are all of them the outcome of the formative forces of the air.

Modern science says: Air is composed of oxygen, nitrogen and a few other substances. The aeriform substance is more or less uniform, only differentiated through inner mechanical movement, such as can be observed in wind. But the air that is described by physics today does not exist, in reality. The air that surrounds our earth is permeated throughout with formative forces. We breathe in these formative forces together with the physical substantiality of the air. Once our organs are complete and we breathe in the air, these formative forces coincide, as it were, with the form of the lung and are not particularly significant except for the purposes of growth. But during the embryonic period, while there is a physical isolation from the external air—then these formative forces of the air work by way of the body of the mother. They build up the lungs and the other organs, with the exception of the muscles and bones. All the inner organs that are to receive life are built up out of the formative forces of the air.

What happens here can be compared—although the comparison is a crude one—to the Chladnic sound figures. Plates covered with fine dust are secured at some point, a violin bow is drawn across the edge of the plate, and then the dust forms itself into certain patterns according to how the violin bow is drawn across the plate. The figures in the dust are formed out of the formative forces produced in the air. So too, the inner organs of man are formed out of the universal formative forces of the air. The lung is formed out of the breathing forces, also the other organs, only the other organs are formed more or less indirectly, the lungs directly. This fact, that the organs are built out of the formative forces of the air, is only to be grasped through inspiration. What has been built out of the air, formed out of the air, has something of the nature of music about it, just as the musical element is at the basis of the Chladnic sound figures.

Much of what modern physiology says is so fundamentally false that one sometimes is embarrassed to say what is correct, so greatly does it differ from what is stated in the ordinary way. In acts of hearing, all the organs of the human being, not only the inner organs of hearing, vibrate together with the air. The whole man vibrates, if only slightly; and the ear is not the organ of hearing just because it vibrates but because it brings to consciousness what is present in the rest of the organism. There is a great but also a subtle, delicate distinction in saying that man hears through the ear, or through the ear is brought to consciousness what has been heard. The human being is built out of sound, although not from sound that is actually heard. Inspiration is required for comprehension of the inner organs. The organization of man's inner organs, of the aeriform man, must be understood by means of inspiration. It is really not to be wondered at that real understanding of the inner organs of man was already lost in days of antiquity, for inspiration was lost and inspiration is the only means whereby the inner organs can be understood. They can be taken from the corpse and diagrams can be made of them, but they cannot be understood by this means.

You see, therefore, that the whole human organism stands really towards the background of the physical world. After reading my book Knowledge of the Higher Worlds, people always get the picture: Here is the physical world and behind it, the spiritual world, in stages or degrees. We reach the nearest spiritual world through imagination, a further spiritual world through inspiration and a further world through intuition. But people do not picture to themselves that of all that is within the human being, the bony system alone is built up by the elementary spirits, whereas the muscular system is built up by spiritual beings of a higher hierarchy. This must be known and understood. A man must be able to reach these beings through imagination if he is to understand the muscles.

To understand the inner organs, still higher spiritual beings must be reached through inspiration. The inner structure of a skeleton, too, can only be truly understood with inspiration. Just think of the following. A modern scientist investigates a plant by analyzing its substance by the methods current today. But this is by no means the plant in its reality. The plant is built up from out of the cosmos, as I said yesterday. It is only the root that is built up from earthly forces. The whole form of the plant is a spiritual reality, a super-sensible reality; this super-sensible reality is then filled with matter. And a man who merely examines this physical matter in the plant is like someone who has a document in front of him that is wet with ink, that he has covered with sand to dry and who then imagines that the sand is the essential thing of the document. The document is covered with this sand and then it is scratched away and the man says: I am examining the sand and I read what the document contains out of the sand. This, more or less, is the way in which people explain the root of a plant, whereas in reality the root is spiritual, filled with physical substance in its framework. So too, the human organs merely receive physical substance.

The reality is that only the bony system is physical; the muscles are etheric, the organs are astral.

If we can attain true intuition we get to the warmth man, the organization that is a space of warmth, inwardly differentiated. The human being actually experiences himself in warmth; his relationship to warmth is not the same as to carbon or nitrogen. Warmth is within him and the human being is within it when he experiences warmth.

The experience of warmth is intense and real and a modern man cannot deny that he has it, whereas he has no inkling of the fact that he experiences air, water, earth. He has no inkling of this because he has grown out of these experiences. Understanding of the warmth involves the application of intuition to the human organization, but it is the delicate differentiations of the warmth in the forms of the organs themselves which have to be perceived and experienced. When intuition can be applied to the warmth organism through the whole body, this form of cognition leads, not, in this case, to an understanding of the inner organs as such, but to the activity of these inner organs. The activity of the inner organs must be grasped by an understanding of the organization within the warmth ether. Every other kind of knowledge is incapable of bringing about understanding of the activity of the organs. The activity of the warmth ether, of the warmth man, must be cognized by intuition.

It will not do simply to think: There is the physical world and one must acquire imagination, inspiration and intuition in order to attain the other worlds. The other worlds are actually present; the etheric world is present in the muscular system, the astral world in the organs and the devachanic world, the spirit world, is present in the warmth man. The spiritual is always around us; it is actually present. Man is a spirit and this spirit is merely filled with physical substance. To say that man is a physical being is an illusion; man in himself is a spirit who actually reaches up into the higher world through his warmth organization.

That is why it is so odd that spiritualists should sit around a table and address themselves to spirits who are far, far inferior to those eight or ten people who are sitting around the table without knowing that they are spirits! This is a truth that must be taken very, very deeply to heart, and then progress can be made.

If through initiation we have grasped the nature of this wonderful activity from organ to organ which goes on in the warmth ether, we find that there are two kinds of warmth. The warmth ether is a quite special element. When any process calls forth a change in the warmth ether, there is always a counter-working. There is always action and reaction with streamings of warmth. The warmth ether is differentiated within itself. There is always a coarser etheric substance which runs counter to a more delicate one.

Suppose you are in a room that is comfortably warm. You make it warmer—so warm that you cannot stand it. That is not merely a physical condition but also a condition of the life of soul. The more delicate warmth is experienced by the soul. The experience of warmth is really always twofold; there is the warmth that we experience psychically and the warmth in which we live, the warmth that is outside the soul; there is the warmth that is within our warmth organism and the warmth that is external to us. Warmth is of the nature of the soul. We can therefore speak of a physical warmth and a soul warmth.

If we pass on to the inner organs, to the aeriform man, where inspiration is needed, here we have the airy element in its main form. Whereas the finer warmth works within warmth, in the aeriform there works light. Intuition reveals warmth within warmth; warmth remains warmth when it is differentiating itself within itself. But this is not the case with air. The real air is not the fantastic air of the physicists which surrounds our earth like another skin. The real air is inconceivable without some condition of light—for darkness is also a condition of light. Light and air belong together; light is an active, organizing force in the whole airy organism. Here we come still further into the realm of soul. There is not only external light but also metamorphosed inner light which permeates the whole human being, which lives in him. The light lives within him together with the air.

Equally, the chemical forces (chemism) are within the human being, together with the water, with the fluid element. Water conceived as physical water, the water of the physicists, is pure fantasy. To picture the fluid element within the human being without the chemical forces is just like picturing a human organism without a head. It can be drawn without a head and the life of soul can be entirely eliminated, but then there is no longer any reality. If you cut the head away from your body, the body cannot live, it is no longer an organism. In the same way, the fluid nature in man is not what the physicists fantastically describe as water. Just as the organism, with the head, forms one whole, so is the fluid organism bound up with the chemical forces. The solid or earthy in the human organism only exists in statu nascendi. Like the water in the human being, it is immediately transformed. Within the human being the earthy is bound up with life.

The physical body and its corresponding etheric body form one whole; they are one unit, seen from two sides. We have the ether stages: warmth, light, chemical forces, life—and we have the physical stages: warmth, air, water, earth. When we give an abstract description of the ethers we give the first place to the warmth ether; when we start from the fluid or solid as the lowest ether, then the highest ether is the life ether. But when we describe the human being we say that the warmth man, the inner activity of the organs, is known by means of intuition. As we descend to the coarsest stage, from the warmth to the earthy in the physical organism, we ascend, in the etheric body, from warmth into life. What does this mean? Think of it. It means that the human being really reverses his own attributes, or qualities. He expends the warmth ether only upon the warmth organism, the light ether upon the airy organism, the chemical ether upon the fluid organism, the life ether upon his solid organization. If you really grasp this, then you cannot think as people ordinarily think. If you insist upon thinking along the ordinary lines, you can, in reality, grasp only the bony system, the earthy human being. It is necessary for you to pass over from ordinary thinking to an inner comprehension of the world, as I have said before.

The fact that medical science has a certain peculiarity is connected with these things. Medical knowledge was an outstanding part of the ancient mysteries where man had real insight into the treatment of a sick human being. The physicians were trained in the mysteries—they were not merely medical men, but they were also sages, wise men who looked after the religious cults. It is natural that the physician should have kept his knowledge secret, as was the case with all mystery knowledge. For you see, if a man wants to know something, he must clothe this knowledge in thoughts; otherwise he floats about in indefiniteness. The picture that comes in imagination, what is heard spiritually (inspiration) and also what is beheld in intuition must all be clothed in thoughts. In ancient times it was known that medical knowledge must be clothed in thoughts. But by clothing it in thoughts it is deprived of some of its efficacy. I am touching here upon deep matters. It cannot be denied that the knowledge of remedies in a sense takes away their power and a really serious physician must deny himself the use of these therapeutic measures which he uses for his patients; he must deny himself and use, for himself, other kinds of healing. Please think about this last sentence and you will realize, in a much deeper sense than before, that the physician must personally cultivate the mood of helping. He must deny himself the healing forces which he applies to his patients. If a man ascribes the efficacy of a remedy merely to the chemical forces, if he imagines that remedies work like steam in a locomotive, he is not submitting to these spiritual laws. But the moment it is realized that the human being reaches up into the spiritual, it will never be doubted that spiritual laws are at the basis of what is contained in the different remedies. In its real essence, medicine is the most wonderful means of education towards selflessness. To demand that therapy should be taught as mechanics or similar subjects are taught is a crude and coarse misunderstanding. The laws of mechanics can, of course, be applied to the human being, but that is valid then to humanity as a whole. And the physician's work is entirely individual. If a physician has a really profound knowledge of some remedy, it is necessary for him, to a certain extent, to deny healing himself by means of this remedy. This is the great education towards selflessness. I will indicate sometime how the physician can help himself. But you must understand in your hearts what underlies these facts. If you take seriously and earnestly what I have said, it will become a world necessity to introduce into medicine not egoism but altruism. Altruism, selflessness, is the basic principle of medicine. Medical morality is not something that has been invented but proceeds from heavenly laws, from laws which the cosmos itself has formed in order to create remedies which follow its own laws.

The more earnestly a communication like this is taken, the more it will be able to contribute to an understanding of the real basis of all remedies.
