7. The Conscious Life of Man
We have been able, in the course of these lectures, to form the impression that the different systems of organs and structural parts of the human being participate in the greatest variety of ways in the combination of processes within the organism. We have referred to various facts in this connection, and have found ourselves already compelled to ascribe as a preliminary the activities at work in the different systems of organs to higher, super-sensible members of the human organism. We had to assert, for instance, that in man the circulation of the blood bears an intimate relation to what we call the human ego, so that we had to speak of the blood as an instrument of the human ego; and, further, we have been able to attribute to the nervous system everything which as conscious life comes to meet this ego. We have at the same time shown how one special portion of the nerve-system, the sympathetic nerve-system, has a function to a certain extent contrary to that of the rest of this system, a function which consists in holding back everything that goes on in the depths of man's organisation, everything that is brought about by the activity of the members of the inner cosmic system in man, so that for the normal consciousness it does not at first force its way up to the horizon of the ego. Yesterday, moreover, we attempted to arrive at an approximate understanding of the fact that what has constructed itself into the firm bony scaffolding, withdraws itself most of all from this conscious life of man; yet at the same time we had to emphasise the fact that, even in this solid scaffolding, a quality of Being must be active such as enables man to evolve an organ for the life of his ego, namely, the circulation of the blood.
We may, therefore, draw the conclusion that the significance of the depositing of the bony system in man, as related to his whole organisation, consists in the fact that he can maintain a human form at all; and that everything expressed in the processes which take place in this solid bony system is kept in the subconscious. We have always to do with something of this kind in the human organisation, and we must be especially clear that something within it is shielded from the influences that play a part in our environment in the great world. We have stated, for example, that the seven members of the inner cosmic system, especially that most spiritual one among them, the spleen, restrain the working of the external laws natural to what we take in as nourishment; that they convey the nutritive substances into the organism in such a manner that they are finally filtered into a form which enables them to exert their powers in conformity with laws and a vital activity of their own. This shielding of the inner processes, this transforming and implanting of outside matter, is most visible and obvious in the warmth of the blood. This blood-warmth, which operates within strict limits of temperature, is regulated by conformity to its own inner laws; and, in this conformity it is, in normal life, independent of what takes place in the warmth-processes of the macrocosm, of the great world about us. Here in the stability of the temperature of the blood we have a perfectly obvious fundamental phenomenon. We must point out, therefore, that one of the most essential elements in the inner organisation of man is that something possessed of Being is cut off within set limits from the macrocosm and develops a vital activity of its own.
Now in order to advance still further in our understanding of the human organism, it will be well for us to-day to proceed for a short while from another direction, so as to direct our attention briefly to the conscious life. We know already from the preceding lectures that the conscious life of man employs the instruments of the blood and the nervous system. We have not, however, been able to go into the finer processes; for this investigation is something, we must frankly confess, still liable to startle the outside world which so depends upon present-day customary science. On the other hand, anyone who has a basis of genuine and true occultism will tell you that the tendency of modern science is leading toward a confirmation, in the course of the next few decades, of those things which we are able to bring forward at the present time, though, to be sure, only through occult observations. If I could hold lectures for half a year, instead of this short series, it would be possible out of the findings of modern science alone to bring forward all that is necessary for external proof of what must be only briefly intimated to-day.1See Grundlegendes fur eine Erweiterung der Heilkunst nach geisteswissenschaftlichen Erkenntnissen, 1925 Philosophisch-Anthroposophischer Verlag, Dornach. As it is, however, I must leave very much to the good will of my audience. It is possible, indeed, in the case of everything stated here, to trace our way to external science which is already in a position, provided it begins with facts and not theoretical prejudices, to discover confirmation, on the basis of its present-day findings, for what may be learned in the sphere of occultism.
Now if we are to start out from our conscious life—and I beg you to understand all these discussions as having such a basis and to consider the relation of the more or less conscious soul-life to our organism—we must keep in mind, as indeed is done in ordinary physiology, all that we call our thought-activity in its most comprehensive sense. We do not need in this connection to go into all the niceties of logical and psychological distinctions, but must simply realise that we have here to do with the thought-life of man, and furthermore, within the realm of our soul's life, with the life of feeling and willing.
You will never find any contradiction among those who have a foundation of true occultism, when it is asserted that all processes in our soul-life which take place on the physical plane, and which fall into any one of the categories of our thinking, feeling, or willing life, are accompanied, in a normal state of consciousness, by actual material processes in the organism, whether endued with life or not. We may find, therefore, that for literally everything which takes place in our soul there are corresponding material processes within our organism. And it is precisely this fact that is of the very greatest interest. For it will be for the first time possible in the next few decades, as a result of certain tendencies in contemporary science, for the present still only tendencies, actually to discover these correspondences between soul-processes and physiological processes, and thus to confirm what we have attained through occultism.
For every thought-process there is a corresponding process within our organism; and the same is true in the case of every emotional process, and every process which may be denoted as an “impulse of will.” We might put it in this way: whenever something takes place in our soul-life it produces a wave which repeats itself as far down as the physical organism. Let us take first the process of thinking, what occurs in thought. And here I wish to call attention to the fact that it is best to fix our minds upon a thought process that is either purely mathematical, or one which is equally objective and which leaves our feeling and willing in a certain sense uninfluenced; that is, we shall first consider thought-processes in pure and unalloyed form. What happens in our organism when such thought-processes go on within our soul-life? Every time we fix upon a thought, there takes place in our organism a process which we may compare with another one of a different kind; by this I do not mean that what I am here stating is an analogy, for it is not an analogy, but an actual fact; and, when I say “we may compare” I mean that this comparison is to lead us to the facts of the matter. We may compare it with what takes place when we dissolve any kind of salt in a glass of water heated to a certain temperature, and by allowing this water to cool cause the salt to crystallise, thus bringing about the very opposite of the process of solution. When the salt is entirely dissolved the water is transparent; but when the water has cooled again, and the opposite process takes place in it, the salt separates itself from the water and crystallises again. There comes about a re-formation of the salt, a depositing of salt in the water. And when we observe water which at first was warm and then is brought to a state in which the salt re-crystallises in it, we see that there within the liquid a solid substance takes form. Something solid settles again, a salt-deposit. (As I said before, I have taken it for granted that these statements as to results of occult research will at first startle anyone who accepts quite pedantically, and in a purely conventional way, the facts recorded by external science.)
Now exactly the same process takes place within our organism when we think. This corresponding process of thinking is a salt-depositing process, so to speak, which is caused by a certain activity in our blood and which irritates and reacts upon our nerve-system, a process, that is, which goes on on the “frontiers” between our blood- and nerve-systems. And just as we can look at the water in the glass and observe the formation of the salt as it separates and crystallises, so we may see, when we observe a human being exercising thought, that just such a process, supersensibly perceptible in all its exactness to the clairvoyant eye, actually does take place. Thus we have here brought before our minds the physical correlative of the process of thought.
At this point we may ask what is the nature of the corresponding correlative of feeling? Here we do not have to do with a depositing of solidifying salt, which is the opposite of the process of solution; but we find that within our organism what we may call refined processes take place which are somewhat like that of a fluid becoming semi-solid. Let us imagine, for instance, a fluid which is just solid enough to take on form—about as much form as there is in very thick albumen: a coagulation, that is, or the thickening of a fluid. Whereas, in the case of thought-processes, we have to do with the direct production of a salt-substance which is deposited out of a fluid, in everything pertaining to feeling we have to do with a transition from an inwardly more fluid state to a semi-fluid one. The substance is here transformed into a somewhat more dense condition which, with clairvoyant sight, may be identified as the formation of small flakes, just as if, in a glass containing a fluid, you were to bring about through certain processes the process of a flake-formation, or an inner changing of a fluid substance into tiny semi-liquid drops.
When we go on to what we may call the cherishing of a will-impulse in the soul, we find that the physical correlative of this again is different. It is, moreover, even easier to grasp; in fact, we come here to that aspect in which the physical is considerably more manifest. The physical correlative of what conforms to will-impulse is a sort of warming-process, a process, indeed, which in some way or other produces certain degrees of heightened temperature within the organism, a becoming hot, in a certain sense. Now we may also conclude from this, since this becoming warm is connected with the whole pulsation of our blood, that it is precisely and altogether with this that the impulses of will are connected. It is not very difficult, if one has even only a moderate capacity for true observation, to be able actually to see that such processes, both in the human and also in the animal organisation, can have their physical correlatives.
Thus we may to a certain extent characterise in this way the physical correlatives which accompany the inner soul-processes. What I have just been characterising is obviously not something of a crude physical nature, but rather extraordinarily fine and minute processes, fine to such a degree, indeed, as cannot usually be imagined. With the exception, perhaps, of the processes of warmth, they are of such a nature that, in comparison with all that we know of similar processes in the outside physical world, they manifest an extreme delicacy. They are processes which the organism carries out by means of all its forces, when the ego is active, with the help of the instrument of the blood: from the process of salt-depositing to the coagulation of fluid and the producing of warmth. They are in part of such a nature that we might say the entire organism is affected by them; or, in the case of the thinking process for example that one part of our organisation, the brain or the spinal cord, is chiefly affected by them. Moreover these processes, which are the results of the influence of soul- processes, are distributed in the most varied way possible in the human organism. When we gradually learn to know that these are facts we come to the point where we are compelled to admit that what we call thoughts or feelings are actual forces, which have a real influence within the physical organisation and which express themselves in real effects; so that, as a result of purely occult observation, we are obliged to speak of a real action of the soul upon the human organism. These real effects in the finer processes will, during the next few decades, reveal themselves gradually and ultimately become entirely accessible to the more refined methods of science, even to external investigation. There will then be an end to that opposition which, arising not out of the facts of science but obviously out of certain preconceived theories with reference to these facts, combats such affirmations as may be based upon occult knowledge.
Now we have also pointed out that what we look upon as a conscious activity of the ego is after all only one part of man's being; and that, below the threshold of what enters in this manner within the horizon of our consciousness there are processes which occur in the subconsciousness, and which are held back from our consciousness, by means of the sympathetic nervous system. We have been able to indicate from various points of view that these processes which take place below the level of consciousness have also a certain kind of connection with our ego. We have said, with regard to the most unconscious part of us, our bony system, that it is organised throughout in such a way as to be able to give to the instrument of the conscious ego the basis for an ego. Thus, out of the unconscious, an ego-organisation arises to meet the conscious ego-organisation. Man is thus divided, as it were, into two parts: from one direction the conscious ego-organisation works into the organism, and from the other there flows into man the unconscious ego-organisation. We have seen that the blood-system and the bony system really form a certain antithesis; they act like opposite poles. The blood in its inner activity responds to and follows, as an instrument, the activity of the ego; on the contrary, that part which is organised as the other pole of the ego so that the ego is able to express itself in the blood, namely the bony system, withdraws itself from the quickened inner life of the ego to such an extent that the ego has no consciousness of anything that goes on within this bony system, and the processes here take their course below the surface of what goes on in the actually conscious ego-life. These are processes, therefore, which correspond to our ego-activity yet at the same time are as truly dead as our blood-processes are living; and they are, as a matter of fact, only one portion of those processes which remain unconscious to the ego, and which only gradually rise more and more up into the conscious.

If we study this bony system thoughtfully with regard to its functioning as a whole in the human organism, we cannot but be struck by the fact that it really withdraws itself, as it were, from all conscious life, and that it does this to a greater degree than any of the other systems of organs. If at the same time we go on from this bony system to the other organic systems, for example, to that inner cosmic system of the liver and spleen, the heart and lungs, etc., we are compelled to affirm that the processes within these systems are also to a very high degree withdrawn from our conscious life, although not so completely as those in our bony system. We certainly need to give far less conscious thought and attention to our bony system than to these other organs just mentioned. Some of these latter make known very clearly in their functions, in the case of some people at any rate, that they do reach up into the plane of consciousness. Just as beings which dwell in the waters of the ocean push the waves up to the surface, so does much of what goes on in the heart or the other organs belonging to these systems push its way up into our conscious life. We know how hypochondriacs, to their own injury, naturally, are partly aware of these things even though in an entirely different way, to be sure, from that in which they actually take place below. I do not here refer at all to the fact that a certain degree of illness may be developed in these organs, for then it is, of course, something quite different which causes the person to become conscious of them. I mean that one need not come anywhere near that borderline which a healthy man may designate as “bordering on being ill.” This border-line, unfortunately, gets very much displaced nowadays, to the great injury of humanity. We know, at the same time, that we are protected from becoming conscious of what goes on below by means of the sympathetic nervous system opposing these inner processes.
If we recognise in the bony system something that so builds man up, as regards his form and structure, that the blood-system can be a fitting instrument within it for the ego, we must have a certain understanding, after what has just been stated, of the fact that the other organs, for example, those organs belonging to the inner cosmic system, are in their turn in a certain sense in the process of growing to meet the conscious life of man which is destined to unfold itself as the flowering of man's organisation. We must see clearly that all of these organs, although they are not permeated with fully conscious life, do nevertheless contain that something which is growing toward our soul-life, just as we have seen that our bony system is growing toward the ego-life.
Now we must ask ourselves at this point: to what extent then, does this inner system, which we may designate as an inner cosmic system, grow toward man's conscious soul-life? If, on the one hand, it is clear to us that in the bony system we have our surest support for what brings order into the blood-system, enabling this blood-system to evolve into an instrument of our ego, and its separate parts to occupy the right places, we must admit, on the other hand, that the function of the bony system as the fundamental basis of our organisation is such that it also supports, at the same time, those organs constituting an inner cosmic system, and brings them into the right position. For the same thing in the bony system which is advantageous to the blood-system is also advantageous to these organs. And, if we make even a purely external study of these organs, we shall be especially struck by the fact that we can discover nothing in them, either in their disposition or even in their form, that is so intimately related to the outer limits of man's form as is the bony system.
We have something then, in man, which we may describe by saying that the bony system is the foundation, and whatever is disposed around it can be thus disposed only because it gives man his basic form. If we recognise in man's skin his external boundary, we must affirm that to a great extent this external skin-boundary is already forecast by the whole structure of the bony system, a fact which led to Goethe saying in such impressive words, not merely aesthetically impressive but wonderfully fine also as a scientific expression: “There is nothing in the skin which is not also in the bones.” That is to say, in the external skin-formation, by means of which man's being is expressed in form, is demonstrated what is already there as a model in the bony system. This we cannot say with regard to our inner cosmic system. Yet, on the other hand, the fact that the functioning of this inner cosmic system thrusts itself up into lower levels of consciousness shows us that it has something to do with our astral body; for the astral body is the bearer of consciousness. And the reason why the astral body as the bearer of consciousness does not consciously experience what goes on in this inner cosmic system is that the sympathetic nerve-system holds it back. This we have already mentioned.
We must affirm, therefore, that this inner cosmic system does not appear to be an expression of the subconscious self, that self which is to be found as a model deep down in the foundation of man's being but, rather, that it is so incorporated in us through the universal cosmic process, that its relation to our astral body is similar to that other relation which enables the human form as expressed in the bony system to offer a basis for the most comprehensive form of the ego. We may say, therefore, that in the bony system, but deep down in the unconscious, we have an already highly developed pattern of the human ego; and that in what we call our inner cosmic system we have the pattern of our so-called astral body. It is important to keep this disposition clearly in mind: the bony system serves as a basic model for all that we call our ego—naturally, we mean this in the sense in which we are here discussing it—and the inner cosmic system for what we call our astral body.
Of course this inner cosmic system, in its entire organisation, since it still lies almost wholly below the level of consciousness, does not in any way derive from the conscious soul-life but is implanted in us, through our external organisation, out of the cosmos. This means that something we may call a cosmic astral element merges with us in such a way that it expresses itself in our inner cosmic system. In our bony system, there is merged into our whole organism, here again out of our whole environment, that which the cosmic process is able to bestow upon us. Since this is connected with the entire form of our physical organisation, we must say that this bony system is really, as a result, the basis of our physical body so far as this appears before us within the boundary of its physical form. A macrocosmic element or, to put it plainly, a cosmic system, which has given us the physical form we have as human beings, has been deposited in our bony system; a macrocosmic astral world-system is deposited in our inner cosmic system. The ego, in so far as it appears as a conscious ego, has the blood-system for its instrument; but, in so far as it is forecast as form, as structure, there lies at its foundation a cosmic force-system which presses into the ego-organisation, into the firm ego-formation, and which sets its deepest imprint in our bony system.
Let us grasp the matter clearly from still another point of view. We know that everything which manifests itself in the ego as a thought-element comes to expression through a kind of salt-deposit, if I may use such an expression as this; for you can well understand that ordinary expressions are scarcely to be found for things which are not in the least understood by the ordinary human consciousness, yet are known by clairvoyant consciousness to be a process of salt-deposit of the finest possible kind. In our bony system, in which our ego was modelled beforehand out of the cosmos, and where it has its firmest support so that the whole organism possesses this support, there also we may accordingly expect to find that a “salt-deposit” must have been forecast for us as thinking beings, and here again through the physical process of salt-depositing. In other words we may expect to find salt-deposits in the bony system. And, in actual fact, we do find that the bones consist of phosphate of lime and calcium carbonate, that is, of salt-deposits.
Thus we have, here again, two opposite poles. Man is a thinking being, and it is the thought-process that makes him inwardly a stable being (for, in a certain sense, our thought-system is our inner bony system; we have definite, sharply-outlined thoughts; and though our feelings are more or less indefinite, wavering, and different in each one of us, the thought-systems are inserted in stable form in the feeling system). Now whereas these stable insertions of thought in the conscious life manifest themselves through a sort of animated, mobile process of salt-depositing, that which prepares the way for these in the bony system, giving them the right support, expresses itself in the fact that the macrocosm out of its own formative processes so builds up our bony system that a part of its nature consists of deposited salts. These deposited salts of the bony system are the quiescent element in us: they are the opposite pole to those inner vital activities which are at play in the process of salt-depositing corresponding to the principle of thought. Thus we are made capable of thought through influences acting from two sides upon our organisation: from one side unconsciously through the fact that our bony system is built up within us; from the other side consciously in that we ourselves bring about, after the model of our bone-building process, conscious processes which manifest themselves as of like nature in our organism, and of which we may say that they are inwardly active processes. For the salt that is here formed must again at once be dissolved by sleep, must be got rid of, for otherwise it would induce destructive processes, causing dissolution. Thus we have processes that begin with salt-depositings and then are followed by destructive processes, constituting a sort of reactionary process. In the re-dissolving of the deposits, beneficent sleep acts upon us in the way we need, to the end that we may ever anew develop conscious thought in our fully awake life of day.
If we proceed further, we can understand that all processes which occur within the human organism must take place between these two polar-extremes of salt-formation. It is with the process of salt-formation in the spiritual sense that we have here to do, but this must be conceived as I have to-day explained it. It will not do simply to say: “Thinking is a process of salt-formation”; for people will then imagine what is now popularly conceived by the untrained person as the process of salt-formation; and then it will be easy to say that Spiritual Science maintains absurdities and nonsense. Between these processes, which must be conceived only in the sense we have indicated, there lie all the other processes to which we have called attention. For, if we have salt-formation occurring in a vitally active thought-process, and the opposite pole of this in the salt-formation of our bony system which has to a certain extent come to rest, we can likewise affirm that we have all through our organs the opposite pole of what we may designate as the liquefying process, as inner coagulation, as a flocculent process, albumen-like insertions or something similar. In this case, again, it is not to be found only under the influence of our own feeling life, which takes its course more in the depths of the soul, but from the bone-building process also. In this connection we must say that all processes which are more inward in character (which belong more to the soul and to the central processes of our organism than does the bone-forming process) are involved in the unconscious liquefying processes and thickening of substances which are formed and deposited as we have described. Now the first thing we come upon here is something in which the bone-building process is actually involved, namely, those liquefying processes to be found in what is mingled with the bone-salts as the so-called bone-glue. In these processes the other pole of our bony system participates and thereby meets that which forms the physical correlative of our feeling process. The process connected with the will impulse expresses itself in a warmth process, an inner warming process, so to speak. Processes of combustion, the formation of combinations which we call inner processes of oxidation, occur throughout our entire organisation; and, in so far as these go on below the threshold of consciousness and have nothing to do with the conscious life, will-impulses and the like, they belong to that other part of our organisation which is shut off by the corresponding organs and is susceptible to influence from the subconscious life.
The human being is thus protected inwardly on one side by a part of his organism in which these processes take their course much as they do outwardly in the macrocosm; and on the other side his protection is such that these processes are connected with his soul-processes, and are of a finer kind as has been explained. And so these physiological processes take place in our organism, salt-forming, liquefying, and warmth producing processes, which are the result of our conscious life; and others which take place outside our conscious life, in such a way that they furnish the basis for what prepares itself beforehand in the human organism in order that the processes adapted to the conscious life may take place. Our organism as a whole is thus a texture woven of those processes which we must describe as belonging in part to our conscious life and in part to the unconscious. It is an extraordinarily significant fact that our organism actually does represent a union formed out of two polaric extremes: that processes of coarser nature take place in such a way that they radiate into the organism, as it were, out of the macrocosm; and that, on the other hand, there are processes of a finer sort which arise out of our conscious life.
Now, since the organism is a single whole and all these parts interpenetrate and influence one another, the situation in this organism, as we have it to-day, is such that all these processes likewise play into one another and that we cannot so separate them one from another as to fix definite boundaries between them. One process plays into another. You need consider only the blood, the most vitally active and finest element. In this element you may perceive a stimulator of the salt-forming process, the process of condensation of a fluid, and the warming process. And likewise in all the systems of organs you may perceive how these processes take their course, and how they are stimulated. Let us therefore say, for example, that when we take nutritive substances from without into our digestive canal these nutritive substances have within themselves what I have called “external vital activity.” They pass through what we may call the first stage of filtering by being taken in and digested by the stomach and what pertains to it; and they are then worked up in more special details by the inner cosmic system, and conveyed to where they can also nourish the finest instrument of the organism, the blood. Thus it is the inner cosmic system which undertakes this first filtering of the nutritive substances, which then have to be conveyed to all the other systems. At the same time, since we have recognised a series of stages in the organic systems of man, we may readily conceive that the most delicate system of all, the blood, must take into itself the most completely filtered vital activities of the nutriment, and that, when anything whatever enters into the blood, it contains by that time only the very least possible amount of that inner vital activity that was in the substances when they were taken in by the stomach. When the substances enter into the stomach they still contain a considerable part of their own nature and essential character, their own vital activity. But when once they are in the blood they must have surrendered all this, in so far as they are nutritive substances that have been conducted into the blood, and must have become something new. The blood is thus something which shields inwardly, in the highest degree, all its processes, something that carries on its processes in the greatest measure independently of the outer world. Such is the blood from he one point of view.
But we have already indicated that this blood is like a tablet which is equally exposed on its two sides, exposed, that is, to impressions coming from both directions. It is turned on the one side to the subconscious processes in the deeper regions of the human organism, where the nutritive substances, after going through filtering processes, come up and force their way to the blood. The influence of everything occurring there is diminished by the sympathetic nervous system, so that it does not reach our consciousness. And the other side of the tablet must be turned by the blood to the experiences of the conscious life of the soul. Not only the unconscious activities of the ego, which work up from the bony system, but also the conscious soul-activities, belonging to the other ego, must penetrate into the blood. They must be able to metamorphose themselves by the time they reach the blood, in order that they then may become the expression of what we have about us in our environment as physical-sensible world; for of course that which is woven into the plant world as ether-body, for example, is not visible to normal consciousness. It is the physical world, first of all, that we have around us; and, for the normal consciousness, we ourselves belong only to the physical world. Thus we expose this other side of our “blood-tablet” to the physical-sensible world which then becomes the content of our consciousness. The entire soul-life, as it is stimulated into thought through the impressions of the physical-sensible world and as it flames into feelings and is stirred into impulses of will, must find its instrument in the blood-system in so far as it is conscious ego-life.
And what does this signify? Nothing other than this: that not only are we able to have in our blood that into which the nutritive substances have been changed, when they have been driven upward from the subconscious and filtered to the point where they may lead a life of their own in the blood, shielded from all macrocosmic laws; but also that there must be inscribed on the other side of the tablet of the blood all that occurs in the physical-sensible realm, in the lifeless matter of the physical-sensible world, which is known to us through sense-impressions and appears to our consciousness, at first, in the form of everything that can make impressions. For whatever goes to make up life can become known to the normal consciousness only through combinations of physical sense-impressions. In reality it becomes known only through the next higher super-sensible member, the ether-body. Thus the blood must be capable of being also related to the physical-sensible world just as this immediately surrounds us.
We may, accordingly, expect to find that something is incorporated into the blood which, we might say, does not manifest itself there as if it were due to the influence of processes working up from the lower depths of our nature, but rather as if it were due to the influence of external macrocosmic laws and vital activities. We must have in our blood, therefore, something that is similar in character and action to direct external processes, which take their course outside of us in the same way in which they gradually come later to take their course within our organism. That is, there must be physical, chemical, inorganic processes which take their course within our blood, which are necessary to enable our ego to take part in the physical world. Thus we shall have to seek in the blood for processes wherein substances can act through their physical-sensible character, in accordance with what they are in the macrocosm. And this we do find, as a matter of fact, in that something is presented to us in the red corpuscles which shows us that it is just beginning to live, and is at the point where it passes over to the state of lifelessness. And from the other side of the tablet something is incorporated into the blood which we may call a process easily comparable to an external process of combustion. In short we have in the blood, disposed on the other side, and recognisable even physically, everything that makes man a physical-sensible being through the fact that in the blood he has an instrument for his ego which is living in this physical-sensible world.
Thus, even concerning the organisation of the blood, physical chemical research itself can show us how significant, how illuminating, occult premisses may be for what is presented to direct inquiry into the physiology of man.
From all the foregoing we may say that we have in the human organism, in the first place, processes which are stimulated by the blood-process in so far as this is related to the outside world, and which constitute physical-sensible processes of the outside world; but that we have also other processes which reach as far as the blood-system from the other direction, and are fitted into this system after they have been filtered to the last degree. Only when we clearly perceive this will the blood appear to us the truly important organ it is. We shall see that it has on the one hand turned its entire being, so to speak, toward life in the very lowest and most basic forms that we know round about us, so that it almost becomes a material substance which tends continually to evoke physical chemical processes in order to be able to serve as an instrument for the ego; and on the other hand that it is the most completely shielded of substances, which carries on inner processes that could not be carried on anywhere else, because everything which is pre-requisite to those processes is dependent upon all the other processes that fit themselves into the processes of the blood. In other words the finest and highest processes which are stimulated out of the depths of our organism unite, within the circuit of our blood, with the other, the physical chemical processes, which obey the laws of the external world. In no other substance does the physical-sensible world come into such direct contact, as does the blood, with something of an entirely different character which, for its very existence, presupposes the activity of super-sensible systems of force. In fact, this blood is something in which the lowliest that man can see in processes around him is blended with the loftiest that can take on organic form within his nature.
It will be entirely clear to us, therefore, that in these blood-processes we have before us something which, if it becomes irregular, unrhythmical, must cause irregularities in the greatest measure in our entire organism. And since the blood is the expression of the whole collection of organic processes we shall have to consider carefully, in connection with irregularities of the blood, where abnormal phenomena are manifest, difficult to distinguish individually, to which particular course of processes we must attribute these irregularities. If, for instance, they are to be found in those processes in the blood-channels which follow the pattern of physical chemical processes in the outer world, we shall then have to be quite clear that these irregularities, which we must learn to recognise and not confuse them, must be dealt with from the side of consciousness, in so far as this consciousness is associated with the physical plane. And here a field is opened, a therapeutic field, which we may think of as one by way of which we shall learn to see whether certain irregularities in the circulation of the blood are connected with such processes as we may call in the true sense of the term physical chemical processes. We shall then be able to intervene by means of such external impressions and appropriate control of external sense-impressions as we can evoke in dealing with a human being, in this case such external impressions as can produce physical chemical processes, that is, through everything which we can convey to the physical organism from without. By this we mean not so much the soul and spiritual impressions we can employ, though these are also included, as all those especially which we can effect through a control of the breathing process, through watching over the breathing process and also over the reciprocal action of the human organism and the external world through the skin.
Then again we can also see in the blood-organism the most delicate organic processes working from the other direction. And we shall have to understand, with reference to this blood-organism, that it represents the third stage in the refinement of our nutritive substances. If the blood-organism, because it evokes those delicate processes of salt forming, liquefaction and warmth under the influence of external impressions, is thereby predetermined from without in its physical chemical course by the soul-processes themselves, we may ask how this process as a blood-process is determined from within. We must distinguish the function belonging to the blood by reason of the fact that it is blood; but we must also understand that it needs to be nourished just like any other organ: we must consider it in the same way as any other organ that needs to be nourished. And on the other hand we must also recognise it as the organ standing at the highest stage of organic activity. With regard to this activity we must consider especially what we call the inner support of human life. The blood, which is the opposite extreme, so to speak, from the bony system, must be most of all protected in order that in our thinking it may create, as the instrument of thought in so far as this thought has ego-consciousness—that it may be able to create the process we have called salification. This protection must proceed from the blood itself; therefore the blood must above everything be capable of calling forth, spiritually as it were, a spiritual bony system, must be able itself to cause the process of salt-forming. This is a task to which the blood must so devote itself that it can be independent of the other organs, and need only receive from the other organs the least possible support for its own work. Least of all do the vital activities of the other organs play into this salifying process of the blood, so that in respect to this process of salification, in relation to thought, the blood is what most of all makes the organism an inner one.
And how can we fail to recognise this, since our thought is the most inward thing we have, that in which we most completely interiorise ourselves to our normal consciousness? Whereas in our feelings we are, to our normal consciousness, at the border-line between the inner and the outer, and in our will-impulses we come into such strong contact with the outer world that under ordinary circumstances the human being no longer recognises himself in his will-impulses! Man recognises himself always in his thoughts, but not in his impulses of will. This may be seen from the fact that there has been so much controversy in the world over the question of the freedom or absence of freedom of the human will, as well as over its other qualities. In our thought-system, which has its physical correlative in a process of salification, we have the innermost aspect of what the blood has to accomplish as an instrument of the ego. And since the process of salification must be completely interiorised and protected against the other organs, this capacity of the blood may be most of all hindered by abnormalities within it. When we note that the blood is so hindered that it no longer manifests its capacity in this direction, we must understand that it needs to be stimulated to that sort of activity which has fallen below a certain border-line in its own particular life.
But the other situation may come about, in which the inner vital activity of an organ, let us say, in this case, the organ of the blood, whose inner vital activity is destined to develop a life of its own, passes beyond a certain limit, exercises unduly this life of its own. Among all occurring human irregularities this is by far the most serious, since it has most of all to do with cases of illness. Only very seldom have we to deal with the opposite condition. It is generally the case that certain parts of the inner organisation are too little protected and therefore too intensely stimulated. When the blood shows itself to be most highly stimulated, when it shows an excessive tendency to develop this activity, it then becomes necessary to counteract this. We can remedy this by introducing the appropriate vital activities from without. In other words, we co-operate in the process of salification, of salt-depositing, by the therapeutic introduction of such substances as contribute to bring it about. This leads us at once to see that a kind of system may be introduced into the way in which we have to deal with the irregularities of our organism.
We may now proceed still farther in this direction. When the organs of our inner astral world, our inner cosmic system, spleen, liver, gall-bladder, etc., are excessive in their inner vital activity, as regards the special character of their functions, how can we deal with them? Here we must call to our minds, above all, that these organs are appointed to a work which goes on all the way up to the circulation of the blood; that they have to prepare beforehand, so to speak, the entire organism, have to direct the nutritive substances as far as the blood by taking them over as they are conveyed into the digestive canal and leading them, with their vital activities transformed, to the blood-system. Hence they are the mediators between these two systems. Just as the blood-system manifests the greatest quickening of inner activity, in so far as it constitutes the thought-system, so it takes on an activity that manifests a connection with our life of feeling, in the way we described when we said that in the process of condensation, of inner liquefaction, the blood-system is supported by what radiates from our inner cosmic system. The blood is left almost entirely to itself in so far as it is the instrument of the element of thought in us; it is stimulated by what radiates upward, by that in which the organs of the inner cosmic system participate, through their own action—so that we have here to call attention to an activity which goes even beyond the individual life of the blood and directs us to the individual life of these organs belonging to the inner cosmic system.
Now, when the functions of these organs, liver, gallbladder, kidneys, lungs, and the rest, develop too intense a vital activity, an overflow of life, we are then concerned with the question how we may in similar fashion deal therapeutically with these processes. We have to paralyse the inner vital activities by introducing something which is adapted to maintain the activity, the vitality, of external cosmic life and thus to paralyse the exaggerated inner vitality. Just as we combat the excessive inner vital activities of the blood, paralyse them, so to speak, by introducing salt-containing substances, so we may also reduce the excessive activity of these organs by introducing substances which develop their own inner vital activities and work in opposition to those of the organs concerned.
Thus the question now arises for us, how we can work on these organs and also on the lowest organs, which have a still lower function: on those digestive organs, namely, which have to do with the preliminary preparation of the nutritive substances for the inner cosmic system. In other words, how shall we deal with the individual organic systems when we consider their gradual upbuilding, stage by stage? In tomorrow's lecture we shall answer the question, “How does the picture of a diseased organ appear to us in the light of occult physiology?” And we shall also show how other organs are incorporated, for example, the system of muscles. And we shall bring our reflections to an end by showing that what confronts us in the already evolved organism is quite plainly connected with the becoming organism, with the human germinal life, indeed, it is precisely here that this is so very distinct, if we are able to presuppose occult principles. It will then become clear to us, quite of itself, how the remaining members participate in the work of the human physical organisation.
Siebenter Vortrag
Wir haben im Verlaufe dieser Vorträge wohl den Eindruck bekommen können, daß sich die verschiedenen Organsysteme und Gliederungen des menschlichen Organismus in der allerverschiedensten Weise beteiligen an dem Gesamtprozesse dieses menschlichen Organismus. Wir haben auf verschiedenes in dieser Richtung hinweisen können und uns schon im Verlaufe der bisherigen Vorträge bemüßigt gesehen, die Tätigkeiten, die in den verschiedenen Organsystemen wirken, vorläufig einmal zuzuteilen höheren, übersinnlichen Gliedern der menschlichen Organisation. So zum Beispiel mußten wir sagen, daß mit dem, was wir das menschliche Ich nennen, in einem innigen Zusammenhange steht der menschliche Blutkreislauf, so daß wir das Blut ansprechen konnten als ein Werkzeug des menschlichen Ich. Wir haben ferner das, was wir Bewußtseinsleben nennen, zuteilen können dem Nervensystem. Wir haben aber auch gezeigt, wie ein besonderer Teil des Nervensystems — das sympathische Nervensystem — in gewisser Weise eine entgegengesetzte Aufgabe hat wie der andere Teil des Nervensystems, eine Aufgabe, welche darin besteht, alles, was in den Tiefen des Organismus des Menschen sich abspielt, was hervorgerufen wird durch die Tätigkeit des inneren Weltsystems, sozusagen zurückzuhalten, so daß es bei normaler körperlicher Verfassung nicht bis zum Horizonte des Ich, also bis ins Tagesbewußtsein heraufdringt. Wir haben gestern ferner versucht, wenigstens annähernd zu erkennen, daß sich dem bewußten Leben des Menschen am meisten das entzieht, was sich in dem festen Knochengerüst aufbaut; wir haben aber doch betonen müssen, wie schon in diesem festen Knochengerüst des Menschen tätig sein muß ein solches Wesenhaftes, das zuletzt den Menschen fähig macht, das Organ seines bewußten Ich-Lebens, den Blutkreislauf, zu entfalten. So können wir auch sagen: die Einlagerung des menschlichen Knochensystems bedeutet für den Gesamtorganismus des Menschen, daß er überhaupt eine menschliche Form erhalten kann und daß alles, was vorgeht innerhalb der Prozesse, die sich in dem festen Knochensystem abspielen, unterhalb der Schwelle des Bewußtseins gehalten wird. Immer haben wir es in der menschlichen Organisation mit etwas ähnlichem zu tun, nämlich damit — wir wollen uns insbesondere in diesem Punkte richtig verstehen -, daß das, was innerhalb dieser menschlichen Organisation ist, gleichsam behütet wird vor den Einflüssen, die in unserem Umkreise und in der großen Welt des Kosmos sich abspielen. Wir haben gesagt, daß die Glieder des iinneren Weltsystems, jene sieben Organe, die gewissermaßen das äußere Planetensystem in unserem Innern spiegeln — insbesondere die Milz -, die äußeren Gesetze dessen, was wir als Nahrung aufnehmen, zurückhalten, gleichsam von diesen Gesetzen befreien, und daß die Nahrungsstoffe so in den menschlichen Organismus aufgenommen werden, daß sie sich als filtriert erweisen, so daß sie nicht in einer solchen Gestalt in den menschlichen Organismus hineinkommen, daß sie innerhalb desselben in einer eigenen Gesetzmäßigkeit und eigenen Regsamkeit walten können. In der, ich möchte sagen, gröbsten Weise haben wir für den Menschen und die höheren Tiere dieses Behüten innerer Vorgänge gegenüber den äußeren Einflüssen ja schon in der Blutwärme gegeben. Diese Blutwärme, die innerhalb enger Temperaturgrenzen liegt, wird durch eine innere Gesetzmäßigkeit erhalten und ist unabhängig von den Wärmevorgängen des Makrokosmos, der großen Welt, die um uns herum sich abspielen. Hier haben Sie recht anschaulich eine Art von Grundphänomen in dieser Konstanz der Blutwärme. So müssen wir immer darauf hinweisen, wie ein Wesentlichstes der inneren Organisation des Menschen darin besteht, daß ein begrenztes Wesenhaftes abgeschlossen wird gegenüber dem Makrokosmos und seine eigenen Regsamkeiten entwickelt.
Nun werden wir heute gut tun, um dem menschlichen Organismus noch weiter beizukommen, ein wenig von der anderen Seite auszugehen und auf das bewußte Leben einen kurzen Blick zu werfen. Wir wissen schon aus den vorhergehenden Vorträgen, wie das bewußte Leben des Menschen sich der Werkzeuge des Blutes und des Nervensystems bedient, wir konnten aber noch nicht auf die feineren Vorgänge eingehen. Was ich jetzt sagen werde, ist etwas, was geeignet ist, die äußere Welt, die heute gebräuchliche Wissenschaft — das sei ganz offen gestanden — noch in hohem Grade zu schockieren. Aber ein jeder, der auf dem Boden des echten, wahren Okkultismus wahrhaft steht, wird Ihnen sagen, daß die Tendenz der Wissenschaft dahin geht, daß durch sie im Verlaufe von wenigen Dezennien auch diejenigen Dinge bestätigt und anerkannt werden, die wir heute noch nur aus okkulten Beobachtungen heraus sagen können. Wenn ich statt einer so kurzen Reihe von Vorträgen ein halbes Jahr über diese Dinge hier sprechen könnte, so wäre es möglich, aus den Ergebnissen der heutigen Wissenschaft alles das herbeizutragen, was geeignet ist, auch äußerlich zu belegen, was im heutigen Vortrag gesagt werden soll. Aber ich muß da manches schon dem eigenen guten Willen und den Fähigkeiten der verehrten Zuhörer überlassen. Es ist ja überall möglich, die Wege zu suchen zur äußeren Wissenschaft, die, wenn sie nicht von theoretischen Vorurteilen, sondern von den Tatsachen ausgeht, auch heute schon überall Bestätigungen finden kann für das, was auf dem Felde des Okkultismus gesagt wird. Ich bitte, alle diese Ausführungen in diesem Sinne zu nehmen.
Wenn wir von unserem bewußten Leben ausgehen, namentlich wenn wir das Verhältnis unseres bewußten Seelenlebens zu unserem Organismus betrachten, ist es zunächst notwendig, alles das ins Auge zu fassen, was wir unsere Denktätigkeit im umfassendsten Sinne nennen. Wir brauchen uns dabei nicht einzulassen auf feinere logische oder psychologische Unterscheidungen, wir brauchen uns zunächst nur vor unsere Seele zu stellen, daß wir es zu tun haben mit dem denkerischen Leben des Menschen, mit dem Gefühlsleben und mit dem Willensleben des Menschen.
Nun werden Sie unter denjenigen, die auf dem Boden des wahren Okkultismus stehen, niemals einen Widerspruch finden, wenn gesagt wird, daß durch alle solche Prozesse, die sich in unserem Seelenleben im wachen Tagesbewußtsein abspielen und die unter die Kategorien des Denkerischen, des Gefühlsmäßigen oder des Willensimpulsmäßigen fallen, im Organismus wirklich materielle — sei es belebte oder andere — Vorgänge bewirkt werden, so daß wir überall für ein jegliches, was in unserer Seele vorgeht, die entsprechenden materiellen Prozesse in unserem Organismus finden können. Das ist von allerhöchstem Interesse. Denn erst in unserer Zeit wird es aus gewissen Tendenzen, die erst heute in der Wissenschaft vorhanden sind, in den nächsten Jahrzehnten möglich sein, diese Entsprechungen von Seelenvorgängen und physiologischen Vorgängen im Organismus wirklich herauszufinden und das aus dem Okkultismus Gewonnene zu bestätigen.
Jedem denkerischen Vorgange entspricht ein Vorgang in unserem Organismus, ebenso jedem Gefühlsvorgange und ebenso jedem Vorgange, der mit dem Ausdruck Willensimpuls bezeichnet werden muß. Gleichsam könnten wir sagen: Wenn in unserem Seelenleben etwas vorgeht, wird eine Welle angeschlagen, die sich bis hinunter in den physischen Organismus fortpflanzt. - Nehmen wir zunächst den Vorgang des Denkens. Da ist es am besten, einen solchen Gedankenprozeß ins Auge zu fassen, der wie das rein mathematische Denken oder ein ähnliches objektives Denken unsere Gefühle und unseren Willen unbeeinflußt läßt. Solche Gedankenprozesse, die denkerische Prozesse «in Reinkultur» sind, wollen wir zunächst ins Auge fassen. Was geht in unserem Organismus vor, wenn sich solche Gedankenprozesse in unserem Seelenleben abspielen? Jedesmal, wenn wir denken, wenn wir Gedanken fassen, findet in unserem Organismus ein Prozeß statt, den wir vergleichen können - ich sage das nicht als Analogie, sondern als eine Tatsache, der Vergleich soll uns auf Tatsachen führen -, den wir vergleichen können mit dem Prozeß einer Kristallisation. Wenn wir in einem Glase Wasser haben, das bis zu einem gewissen Grade erwärmt ist, und darin irgendein Salz, Steinsalz zum Beispiel, aufgelöst haben und bringen nun durch Abkühlung des Wassers dieses aufgelöste Salz zur Kristallisation, dann vollzieht sich der der Auflösung entgegengesetzte Prozeß. Wenn das Salz ganz aufgelöst ist, ist das Wasser durchsichtig. Wenn aber das Wasser wieder abgekühlt wird und der der Auflösung entgegengesetzte Prozeß im Wasser sich vollzieht, dann wird das Salz wieder herauskristallisiert aus dem Wasser; es geschieht eine Salzrückbildung, eine Salzeinlagerung im Wasser. Der Prozeß stellt sich also so dar, daß wir sehen: In dem vorher warmen Wasser entsteht, wenn wir es abkühlen, ein Festes; es lagert sich im Flüssigen ein Festes ein, eine Salzablagerung. Wie gesagt, ich habe vorausgesetzt, daß durch die Angaben okkulter Resultate derjenige, der nur pedantisch im rein philiströsen Sinne die Tatsachen zugeben will, die von der Wissenschaft registriert sind, zunächst schockiert werden kann.
Ein ganz gleicher Prozeß spielt sich nun ab in unserem Organismus, wenn wir denken. Es ist der Prozeß des Denkens entsprechend einem Einlagerungsprozeß von Salzen, der ausgeht von einer Wirkung unseres Blutes und der irritierend zurückwirkt auf unser Nervensystem, ein organischer Prozeß also, der sich abspielt an der Grenze unseres Blutes und unseres Nervensystems. Und geradeso, wie wir beim Anschauen des Wassers in dem Wasserglase das Auskristallisieren des Salzes beobachten können, so können wir sehen, wenn wir einen Menschen beobachten, der in der befriedigenden Lage ist zu denken, wie sich in der Tat — für das hellseherische Auge sehr genau übersinnlich wahrnehmbar - ein solcher Prozeß abspielt. So haben wir das physische Korrelat des Denkprozesses einmal vor unsere Seele hingestellt.
Fragen wir uns jetzt: Wie nimmt sich das Entsprechende beim Fühlen aus? — Beim Fühlen haben wir es nicht mit einer Einlagerung von festwerdenden Salzen, also nicht mit einem umgekehrten Auflösungsprozeß zu tun, sondern es finden in unserem Organismus feine Prozesse statt, die sich etwa so abspielen, wie wenn ein Flüssiges halbfest wird. Denken Sie sich: Ein Flüssiges wird so halbfest wie etwa flüssiges Eiweiß, es koaguliert zur Konsistenz von verdicktem Eiweiß; also es findet ein Festwerden eines Flüssigen statt. Während wir es beim Denkprozeß zu tun haben mit einem Herausholen eines Festen, Salzartigen aus einem Flüssigen, das sich ablagert, haben wir es beim Gefühlsmäßigen zu tun mit einem Übergehen gewisser Teilchen im Blut aus einem mehr flüssigen Zustand in einen dichteren Zustand. Die Substanz selber wird durch eine Art Gerinnung in einen dichteren Zustand gebracht. Dem hellseherischen Auge zeigt sich das wie ein Sichbilden kleiner Flöckchen, geradeso, wie Sie in einem Glase, in welchem eine bestimmte Flüssigkeit ist, durch bestimmte Vorgänge einen Prozeß innerer Flockenbildung bewirken können, ein Ausscheiden quellbarer kleiner Tröpfchen aus einer flüssigen Substanz.
Wenn wir jetzt übergehen zu dem, was wir unsere Willensimpulse nennen können, so ist das physische Korrelat dafür wiederum anders. Das ist nun sogar leichter zu fassen, denn da kommen wir nach der Seite, wo die Sache schon etwas offenbarer wird. Der unseren Willensimpulsen entsprechende physische Prozeß ist eine Art Erwärmungsprozeß, der Temperaturerhöhungen im Organismus hervorruft, eine Art Heißwerden des Organismus in gewisser Beziehung. Da nun diese Erwärmung eng mit der ganzen Pulsation des Blutes zusammenhängt, so können wir sagen, daß die Willensimpulse mit einer Temperatursteigerung des Blutes verbunden sind. Dazu gehört nicht viel; wenn man nur einigermaßen Sinn hat für wirkliche Beobachtungen, kann man auch schon am tierischen Organismus beobachten, daß die Willensimpulse in der Erwärmung des Blutes ihr physisches Korrelat haben.
So können wir die physischen Korrelate, die sich abspielen bei inneren, seelischen Vorgängen, einigermaßen charakterisieren. Was ich Ihnen jetzt charakterisiert habe, ist natürlich nicht etwas, was sich sehr im groben abspielt, sondern das sind außerordentlich feine, minuziöse Prozesse, Prozesse von einer Feinheit, von welcher man sich allerdings gewöhnlich gar keine Vorstellung machen kann. Aber mit Ausnahme der Erwärmungsprozesse spielen sich diese Prozesse so ab, daß sie in bezug auf alles, was wir an ähnlichen Prozessen in der äußeren physischen Welt kennen, eben eine ungeheure Feinheit darbieten. Alles dieses sind Prozesse, die der Organismus durch seine gesamten Kräfte ausführt, wenn das Ich in Tätigkeit ist, mit Hilfe des Instrumentes des Blutes. Von der Salzablagerung bis zur Quellbarkeit und zur Erwärmung spielen sich diese Prozesse so ab, daß der ganze Organismus ergriffen wird oder auch, zum Beispiel beim denkerischen Prozeß, hauptsächlich ein Teil unseres Organismus, Gehirn und Rückenmarksystem. In der mannigfaltigsten Weise im menschlichen Organismus verteilt sind diese Prozesse, welche Folgen der Einwirkung der seelischen Prozesse sind. Wenn man diese Dinge allmählich als Tatsachen kennenlernt, kommt man dahin, allerdings zugeben zu müssen, daß das, was man Gedanken oder Gefühle oder Willensimpulse nennt, reale Kräfte sind, die reale Wirkungen haben innerhalb des physischen Organismus und sich in realen Wirkungen aussprechen. Wir müssen rein aus der okkulten Beobachtung heraus sprechen von einer realen Wirkung der Seele auf den menschlichen Organismus. Es werden sich diese realen Wirkungen auf den menschlichen Organismus nach und nach in den folgenden Jahrzehnten der Wissenschaft schon enthüllen. Diese feinen Prozesse im Organismus werden den sorgfältigeren und subtileren Untersuchungsmethoden der Wissenschaft schon zugänglich werden; und dann wird jenes Sträuben mehr und mehr von selber aufhören, das heute — nicht aus den Tatsachen, die die Wissenschaft erforscht hat, wohl aber aus gewissen vorurteilsvollen Theorien, die an diese Tatsachen sich anknüpfen - sich erhebt gegen Behauptungen, die aus der okkulten Erkenntnis gemacht werden können.
Nun haben wir noch darauf hingewiesen, daß das, was wir als eine bewußte Tätigkeit des Ich auffassen, im Grunde genommen nur ein Teil der menschlichen Wesenheit ist und daß unter der Schwelle dessen, was auf diese Art in unseren Bewußtseinshorizont hereindringt, Prozesse sich abspielen, die unterhalb des Bewußtseins liegen und die gleichsam ferngehalten werden von unserem Bewußtsein durch das sympathische Nervensystem. Wir haben von verschiedenen Seiten her darauf hinweisen können, wie das, was wir dergestalt unbewußt in uns tragen, auch in einer gewissen Art im Zusammenhange steht mit unserem Ich. Wir haben von dem Unbewußtesten, von unserem Knochensystem, gesagt, daß es von vornherein so organisiert ist, daß es dem Werkzeuge des bewußten Ich geradezu die Grundlage geben kann. So wächst aus dem Unbewufßten heraus eine unbewußte Ich-Organisation der bewußten Ich-Organisation entgegen. Gleichsam teilt sich für uns der Mensch in zwei Teile: Es wirkt von der einen Seite her die bewußte Ich-Organisation und von der anderen Seite her die unbewußte Ich-Organisation in den Menschen hinein (siehe Zeichnung S. 136). Wir haben in dieser Beziehung gesehen, daß Blutsystem und Knochensystem einen gewissen Gegensatz bewusste Ich-Organisation bilden, sich wie entgegengesetzte Pole ausnehmen. Während das Blut in seiner inneren Regsamkeit als ein schmiegsames Werkzeug der Tätigkeit des Ich folgt, entzieht sich der andere Pol, das Knochensystem, der Regsamkeit des Ich so, daß von allem, was im Knochensystem geschieht, das Ich kein Bewußtsein hat, das heißt, daß alle im Knochensystem vorgehenden Prozesse vollständig unter der Oberfläche der eigentlichen bewußten Ich-Geschehnisse ablaufen. Es sind zwar Prozesse, welche unserer Ich-Tätigkeit entsprechen, aber sie sind ebenso tot, wie unsere Blutprozesse lebendig sind; sie sind damit im Grunde genommen ein Teil solcher Prozesse, die dem Ich unbewußt bleiben, die sich nur stufenweise herauferheben aus dem Unbewußten zum Bewußtsein.

Wenn wir das Knochensystem in seiner Gesamtfunktion im menschlichen Organismus einmal eingehend betrachten, so muß uns ja überall auffallen, daß es sich allem bewußten Leben entzieht, und zwar am stärksten von allen Organsystemen. Wenn wir aber nun vom Knochensystem übergehen zu den Organsystemen, die wir das innere Weltsystem des Menschen genannt haben, zum Leber-GalleMilzsystem, zum Lungen-Herzsystem und so weiter, so müssen wir nach dem in den früheren Vorträgen hierüber Mitgeteilten sagen: In hohem Grade sind die Vorgänge innerhalb dieser Systeme auch unserem Bewußtsein entzogen, aber doch nicht ganz so, wie die Vorgänge in unserem Knochensystem. An unser Knochensystem brauchen wir doch viel weniger zu denken, auf dasselbe zu achten als auf die Organe, die eben genannt worden sind. Einige dieser genannten Organe geben sich dem Menschen sogar sehr deutlich in ihren Funktionen kund als etwas, was über das Unbewußte herausragt. Es ist etwa so, wie wenn ein Gegenstand, der im Wasser des Meeres schwimmt, teilweise heraufstößt und wie eine Insel über der Oberfläche sichtbar wird. So dringt zum Beispiel manches von dem, was im Herzen vorgeht, in das Bewußtsein herauf. Sie wissen ja aus Erfahrung, wie besonders hypochondrische Naturen — zu ihrem Schaden natürlich — etwas von den Dingen verspüren, die in ihren inneren Organen vorgehen, allerdings wird es ihnen ganz anders bewußt, als es drinnen vorgeht, aber sie empfinden es doch. Ich spreche jetzt nicht davon, wie es ist, wenn ein gewisser Grad von Erkrankung in den Organen schon eingetreten ist. Beim Krankwerden nämlich wird man sich der Organe bewußt; da liegt aber eine wirkliche Ursache vor, wodurch die Wirkungen der inneren Weltsysteme heraufsteigen bis in das Bewußtsein; sondern ich spreche davon, daß lange nicht diese Grenze erreicht zu werden braucht, welche ein gesunder Mensch gegenüber dem Kranksein hat. Diese Grenze verschiebt sich aber leider recht oft. Was oft schon als Krankheit angesprochen wird, kann durchaus als ein geringerer oder höherer Grad des Hinaufdringens innerer Vorgänge in das Bewußtsein angesehen werden. Wir müssen also wirklich die Ursachen der verschiedenen Krankheiten immer so untersuchen, daß wir uns fragen: Liegen die Ursachen der Schmerzen in Krankheiten der Organe, oder haben wir sie anderswo zu suchen? - Wir wissen ja, daß wir vor dem Ins-Bewußtsein-Treten dessen, was sich da unten im Organismus abspielt, geschützt sind durch das sympathische Nervensystem.
Wenn wir im Knochensystem etwas sehen, was den Menschen seiner Form, seiner Gestaltung nach so aufbaut, daß das Blutsystem darin in der entsprechenden Weise ein Werkzeug für sein Ich sein kann, so müssen wir uns nach dem, was eben jetzt gesagt worden ist, darüber klar sein, daß auch die anderen Organsysteme in einer gewissen Weise dem bewußten Leben des Menschen, das sich zuletzt wie eine Blüte entfalten soll, entgegenwachsen. Wir müssen uns klar sein, daß alle diese Organe auch schon, obwohl sie nicht durchdrungen sind von vollbewußtem Leben, das enthalten, was unserem bewußten Seelenleben entgegenwächst, so wie wir gesehen haben, daß unser Knochensystem entgegenwächst dem Ich-Leben.
Wir müssen uns nun die Frage vorlegen: In welchem Grade wächst denn dieses innere System, das wir als ein inneres Weltsystem bezeichnet haben, dem bewußten Seelenleben des Menschen entgegen? — Wenn wir auf der einen Seite bedenken, daß wir in dem Knochensystem die festeste Stütze in unserem physischen Körper haben, die dem Blutsystem so seine Anordnung gibt, daß es an den richtigen Orten wirkt, um sich als Werkzeug des Ich entfalten zu können, so müssen wir auf der anderen Seite auch sagen, daß das Knochensystem diejenigen Organe stützt und in der richtigen Lage hält, die wir früher als innere Weltsysteme bezeichnet haben. Denn was mit dem Blute geschieht, das kommt auch diesen Organen zugute. Wenn Sie alle diese Organsysteme betrachten, wird Ihnen auffallen, daß Sie in deren Anordnung nichts entdecken können, was so wesentlich und innig mit der äußeren Form des Menschen zusammenhängt wie das Knochensystem. Es ist die Grundlage der menschlichen Form, und was sich um das Knochensystem herum hineinbaut und auflagert, das kann sich nur so hineinbauen und auflagern, weil das Knochensystem die Grundform abgibt. Auch die Haut als äußere Körperbegrenzung ist gleichsam vorgebildet durch die ganze Gestaltung des Knochensystems. Goethe hat das in einem schönen Ausspruch gesagt, nicht bloß vom ästhetischen, sondern auch vom wissenschaftlichen Standpunkt aus: «Es ist nichts in der Haut, was nicht im Knochen ist.» Das heißt, in der äußeren Hautgestaltung drückt sich dasjenige aus, was schon durch das Knochensystem vorgebildet ist. Dasselbe können wir von unserem inneren Weltsystem nicht sagen. Andererseits zeigt aber gerade das Heraufrücken der Wirkungen des inneren Weltsystems zu niederen Graden des Bewußtseins, daß dieses innere Weltsystem etwas zu tun hat mit unserem Astralleib; denn der Astralleib ist der Träger des Bewußtseins. So müssen wir daher sagen, daß zwar dieses innere Weltsystem uns nicht erscheinen kann als ein Ausdruck des unterbewußten Ich, des in tiefen Untergründen gelegenen formbildenden Ich, daß es uns aber als das erscheinen kann, was uns durch den ganzen Weltenprozeß als Ausdruck der Umwelt so eingegliedert ist, daß es einen ähnlichen Bezug hat zu unserem Astralleib, wie das Knochensystem die Grundlage abgibt zu der das Ich umfassenden menschlichen Form. Wir können daher sagen: Wir haben im Knochensystem schon vorgebildet, tief unten im Unterbewußten, das menschliche Ich, und in dem, was wir unser inneres Weltsystem nennen, haben wir dasjenige vorgebildet, was wir unseren Astralleib nennen.
Nun stammt dieses innere Weltsystem in seiner ganzen Organisation, weil es eben noch unter dem Bewußtsein liegt, gar nicht aus dem bewußten Seelenleben; es ist unserem Organismus eingefügt aus dem Makrokosmos. Es ist also damit dem Menschen etwas, was wir ein kosmisches Astrales nennen können, so eingefügt, daß es sich ausdrückt als unser inneres Weltsystem. Und in unserem Knochensystem haben wir wiederum in unseren Organismus etwas eingegliedert bekommen aus unserer Umgebung, aus dem großen Weltsystem, und weil das zusammenhängt mit der gesamten Form unseres physischen Organismus, müssen wir sagen: Dieses Knochensystem ist eigentlich dadurch die Grundlage für unser Ich in unserem physischen Leib, weil es ein makrokosmisches oder schlechtweg ein kosmisches System ist, das uns zu diesem physisch gestalteten Menschen macht. Neben diesem Knochensystem wird uns eingelagert ein makrokosmisches astrales Weltsystem als unser inneres Weltsystem. Insofern unser Ich als bewußtes Ich auftritt, hat es zum Werkzeug das Blutsystem, insofern unser Ich vorgebildet ist als Form und Gestalt, liegt ihm zugrunde ein kosmisches Kraftsystem, das hindrängt zur festen Gestaltung, das sich am dichtesten zum Ausdruck bringt in unserem Knochensystem.
Fassen wir die Sache noch von einem anderen Gesichtspunkt ins Auge. Wir wissen ja jetzt, daß alles, was wir als bewußte Denktätigkeit, die vom Ich bewirkt wird, bezeichnet haben, sich zum Ausdruck bringt durch eine Art von feinster Salzablagerung im Blut. Es gibt sich also das bewußte Denken zu erkennen durch eine Art von innerer Salzablagerung. Wir können daher also erwarten, daß da, wo aus dem Kosmischen heraus unser Knochensystem vorgebildet wird, so daß der Organismus die materielle Stütze bilden kann für den Menschen als denkerisches Wesen, wir auch den physischen Prozeß einer Salzablagerung finden müßten. Wir müßten also Salzablagerungen im Knochensystem finden können; und tatsächlich bestehen die Knochen zum Teil aus phosphorsaurem und kohlensaurem Kalk, also aus abgelagerten Kalksalzen.
So haben wir auch hier die beiden entgegengesetzten Pole. Indem der Mensch denkerisch tätig ist, sind die Gedankenprozesse dasjenige, was uns innerlich zu einem festen Wesen macht. Unsere Gedanken sind in einer gewissen Weise unser inneres Knochengerüst. Der Mensch hat bestimmte scharfumrissene Gedanken; unsere Gefühle dagegen sind unbestimmt, lavierend, bei jedem Menschen mehr oder weniger anders. Die Gedanken bilden feste Einschlüsse im Gefühlssystem. Während diese festen Einschlüsse im bewußten Leben sich ausdrücken im Blut durch eine Art von regsamem, beweglichem Salzablagerungsprozeß, drückt sich das, was das Ich vorbereitet, im Knochensystem so aus, daß der Makrokosmos unser Knochensystem so bildet, daß es zum größten Teil aus abgelagerten Salzen aufgebaut ist. Diese sind nun das ruhende Element in uns, der andere, der entgegengesetzte Pol zu den Vorgängen der inneren Regsamkeit, welche in den Salzablagerungsprozessen im Blut sich abspielen. So werden wir als Menschen von zwei Seiten her in unserer Organisation zum Denker gemacht, von der einen Seite her unbewußt, indem unser Knochensystem aufgebaut wird, von der anderen Seite aus bewußt, indem wir — nach dem Muster unseres Knochenaufbauprozesses — dieselben Prozesse bewußt vollziehen, die sich im Organismus als solche Salzablagerungsprozesse zeigen, von denen wir sagen können, daß sie innerlich regsame sind. Die beim Denken gebildeten Salze müssen sogleich durch den Schlaf wieder aufgelöst, fortgeräumt werden, sonst würden sie etwas wie Zersetzungsprozesse, Auflösungsprozesse im Organismus herbeiführen. Wir haben also im Denken einen wirklichen Zerstörungsprozeß zu sehen. Und durch den wohltätigen Schlaf wird ein Rückbildungsprozeß ausgeübt, der bewirkt, daß das Blut wieder frei wird von Salzablagerungen, so daß wir von neuem bewußte Gedanken im wachen Tagesleben entwickeln können.
Es geht aber nicht an, daß man nun einfach sagt: Denken ist ein Salzbildungsprozeß -, denn wenn die Menschen das nicht in der richtigen Weise verstehen, könnte wohl jemand sagen, die Geisteswissenschaft behaupte das dümmste Zeug.
Gehen wir nun weiter. Wir können uns denken, daß zwischen diesen beiden äußersten Polen der Salzbildung sich alle anderen Prozesse im menschlichen Organismus abspielen, und zwar im wesentlichen diejenigen, auf die wir schon hingewiesen haben. Wie wir regsame Salzbildungsprozesse haben durch das Denken, die ihren Gegenpol haben im Salzbildungsprozeß in den Knochen, der bis zu einem gewissen Grade zur Ruhe gekommen ist, so haben wir auch einen Gegenpol zu demjenigen, was wir bezeichnet haben als den innerlichen Quellungsprozeß, als Koagulation, als Flockenbildungsprozeß, als etwas Ähnliches wie eiweißartige Einschlüsse, welche unter dem Einflusse unseres Gefühlslebens entstehen, als äußeren Ausdruck unseres Gefühlslebens. Dieser Gegenpol zeigt sich in dem, was mehr innere Prozesse unseres Organismus sind, und nimmt teil an einem solchen unbewußten Quellen, an einem Dichterwerden von Substanzen, welche sich bilden und einlagern als Wirkung des makrokosmischen Astralsystems. Es ist der Knochenleim, der teilnimmt an dem Knochenbildungsprozeß und der den anderen Knochensubstanzen eingefügt wird. Das ist der andere Pol des Quellungsprozesses gegenüber dem, was als physisches Korrelat durch unser Gefühl entsteht.
Unsere Willensimpulse drücken sich ja organisch in einem Wärmeprozeß, in einem inneren Erwärmungsprozeß aus. Verbindungen, die sich bilden und die wir bezeichnen können als Produkte innerer Verbrennungsprozesse, als innere Oxidationsprozesse, finden sich durch unseren ganzen Organismus hindurch. Und insofern sie unter der Schwelle des Bewußtseins verlaufen und nichts zu tun haben mit dem bewußten Leben, gehören sie der anderen Seite an, dem Gegenpol, der abgeschlossen ist von dem, wovon das bewußte Leben Einflüsse erhalten kann. Dadurch ist der Mensch durch einen Teil seines Organismus innerlich geschützt vor Störungen, damit sich innerhalb desselben Prozesse vollziehen können, die von größter Zartheit sind, die von dem Seelenleben veranlaßt sind.
Wie wir erfahren haben, finden also in unserem Organismus solche physiologische Vorgänge wie Salzbildung, Quellbildung und Wärmebildung statt, die unserem bewußten Leben folgen, und solche Prozesse, die außerhalb unseres bewußten Lebens sich so abspielen, daß sie erst die Grundlage abgeben für das, was sich vorbereitet im menschlichen Organismus, damit das bewußte Leben sich überhaupt entfalten kann. So also ist unser gesamter Organismus ein Durcheinanderweben von Prozessen, die wir als unserem bewußten Leben zugehörig, und solchen, die wir als unserem unbewußten Leben zugehörig zu bezeichnen haben. Das ist eine außerordentlich bedeutungsvolle Tatsache, daß unser Organismus wirklich etwas darstellt wie ein Zusammengehöriges aus zwei Polaritäten: daß sich gleichartige Prozesse einmal so vollziehen, daß sie hereinragen in den Organismus aus dem Makrokosmos und gleichsam im gröberen sich abspielen, und auf der anderen Seite solche Prozesse, welche als Folgen des bewußten Lebens des Menschen im feineren vor sich gehen können.
Nun ist im heutigen fertigen Organismus die Sache so, daß alle diese Prozesse durchaus ineinanderspielen und daß wir sie, so wie der Organismus vor uns steht, nicht eigentlich so voneinander trennen können, daß wir überall bestimmte Grenzen zu bezeichnen vermöchten; der eine Prozeß spielt in den anderen hinein. Sie brauchen nur das Blutsystem, das regsamste, feinste Element zu betrachten. Im Blut sehen Sie sowohl den Erreger der Salzablagerungsprozesse wie auch der Prozesse der Koagulierung einer flüssigen Substanz und auch der Erwärmungsprozesse. In ähnlicher Art finden wir diese Prozesse auch bei anderen Organsystemen miteinander in enger Beziehung stehend. Wenn wir zum Beispiel Nahrungsmittel von außen in unseren Verdauungskanal aufnehmen, so haben diese Nahrungsmittel noch das, was ich als ihre äußere Regsamkeit bezeichnet habe. Sie machen eine erste Stufe der Durchsiebung durch, indem sie aufgenommen werden im Munde und durch den Kauprozeß vorbereitet werden für den Verdauungsprozeß im Magen; in weiterer Stufenfolge werden sie verarbeitet durch die Organe, die wir als das innere Weltsystem bezeichnet haben, und endlich werden sie herangeführt bis dahin, wo sie das feinste Instrument des menschlichen Organismus, das Blut, ernähren können. Nachdem wir so in gewisser Beziehung eine Stufenfolge der Durchsiebung der Nahrungsstoffe durch die inneren Organsysteme angedeutet haben, können wir uns jetzt leicht denken, daß in der Tat das feinste System, das Blutsystem, sozusagen die durchgesiebtesten Nahrungsregsamkeiten in sich aufnehmen muß und daß das, was an das Blut herantritt, schon am allerwenigsten von demjenigen enthält, was die Nahrungsstoffe an eigener Regsamkeit in sich hatten, als sie aufgenommen wurden. Wenn die Stoffe aufgenommen werden, haben sie noch ein gut Teil ihrer eigenen Natur und Gesetzmäßigkeit. Sie haben diese im Magen und den weiteren Organsystemen, die sie passierten, aufgeben müssen, und soweit sie sich im Blut befinden, sind sie zu etwas vollständig Neuem geworden. Daher ist das Blut auch dasjenige Organ, das am meisten von allen geschützt ist gegen die Eindrücke der Außenwelt, das seine Prozesse am meisten unabhängig von der Außenwelt vollzieht. Das ist die eine Seite; aber wir haben schon eingehend gezeigt, daß das Blut nach zwei Seiten sich wendet, daß es wie eine Tafel sowohl nach der einen wie nach der anderen Seite hin Einwirkungen ausgesetzt ist. Das Blut wird auf der einen Seite ja zu denjenigen Organen in den tieferen Regionen des menschlichen Organismus hingeführt, wo alles, was an Prozessen vorgeht, durch das sympathische Nervensystem zurückgehalten, abgewehrt wird, so daß es nicht zum Bewußtsein kommt. Nun muß das Blut sich ja auch der anderen Seite zuwenden, den Erlebnissen des bewußten Seelenlebens. Es muß nicht nur die unbewußten Vorgänge aufnehmen, sondern es muß auch das bewußte Ich sich einprägen dem Blut. Unsere bewußten Seelentätigkeiten müssen sich so wandeln können, bis sie das Blut erreichen, damit sie in diesem Blute zum Ausdruck werden für das, was wir um uns haben. Was haben wir denn um uns? Die physisch-sinnliche Welt; denn das, was der Pflanzenwelt eingegliedert ist - der Ätherleib -, das ist für das normale Bewußtsein nicht da. Für das helle Tagesbewußtsein gehört der Mensch nur der physischen Welt an; die Lebenswelt ist für uns unsichtbar.
So stehen wir mit der anderen Seite der Blutstafel der physischsinnlichen Welt gegenüber. Das ganze Seelenleben, wie es verläuft unter den Eindrücken der physisch-sinnlichen Welt, wie es zu Gedanken erregt wird, wie es zu Gefühlen entflammt wird, wie es zu Willensimpulsen angeregt wird, das muß alles im Blutsystem sein Werkzeug finden können, insofern es bewußtes Ich-Leben ist. Das alles muß im Blut pulsieren können. Was heißt das? Das heißt nichts anderes, als daß wir in unserem Blut nicht nur dasjenige haben dürfen, was aus den Nahrungsstoffen ist, nachdem sie in hohem Grade filtriert, ihrer Eigenregsamkeit enteignet, geschützt von allen makrokosmischen Gesetzen sind, sondern es muß — damit das Einschreiben auf die Blutstafel auch von der anderen Seite möglich ist — in dem Blut auch etwas zu finden sein, was verwandt ist mit dem Physisch-Sinnlichen, mit dem Unlebendigen der physisch-sinnlichen Welt. Was das Leben ausmacht, kann ja für das gewöhnliche Bewußtsein nur durch Kombination der physisch-sinnlichen Eindrücke erkannt werden, in seiner Wirklichkeit kann es erst erkannt werden durch das unterste übersinnliche Glied der menschlichen Wesenheit, durch den Ätherleib.
Das Blut muß also verwandt sein mit der physisch-sinnlichen Welt, so wie diese unmittelbar ist. Wir werden nun sehen, daß sich dem Blute etwas eingliedert, wovon wir sagen können: Das ist nun nicht so in unserem Blut, wie wenn es bestimmt würde durch die Prozesse, die aus unserem Wesen, aus den Tiefen unseres Organismus heraufdringen zum Blut, deren Gesetzmäßigkeit also der unsrigen angepaßt ist, sondern es ist so, als ob es durch die Wirkungen äußerer makrokosmischer Gesetzmäßigkeiten und Regsamkeiten unserem Blut eingegliedert würde. Wir müssen in unserem Blut etwas haben, was so ist und so wirkt wie unmittelbare äußere Prozesse, die aber innerlich sich geradeso abspielen wie äußerlich im Makrokosmos, die also ihre Eigengesetzmäßigkeit nicht verlieren. Es müssen also in unser Blut physische, chemische, anorganische Prozesse hineinspielen; die sind notwendig, damit unser Ich Teilnehmer werden kann an der physischen Welt. Wir werden also in dem Blut solche Stoffe zu suchen haben, die so wirken können, daß ihr physischer Charakter, ihre Eigengesetzmäßigkeit beibehalten wird. Das finden wir in der Tat im Blut. In unseren roten Blutkörperchen ist uns etwas gegeben, das deutlich zeigt, daß es eben erst zu leben anfängt und an dem Punkte ist, wo es vom Leben in die Leblosigkeit übergeht. Auf der anderen Seite haben wir dem Blut eingegliedert einen fortwährenden Erwärmungsprozeß, der sich vergleichen läßt mit einem äußeren Verbrennungsprozeß, wo der Oxidationsprozeß wieder neue Lebensmöglichkeiten gibt. Wir haben also dem Blute eingeordnet dasjenige, was den Menschen zu einem physisch-sinnlichen Wesen macht.
So zeigt sich uns bis in die Organisation des Blutes hinein, wie bedeutsam die physische, die chemische Untersuchung erleuchtet werden kann durch das, was aus okkulter Anschauung mitgeteilt werden kann, und wie diese erst verständlich macht, was sich dem unmittelbaren äußeren Anblick darbietet.
So können wir sagen: Wir haben im menschlichen Organismus, im Blut, Prozesse, die angeregt werden durch die Einwirkung der Außenwelt, die physisch-sinnlicher Art sind; wir haben außerdem aber auch solche Prozesse im Blut, die von der inneren Seite her heraufreichen und die auf der Einlagerung der bis zum äußersten Grade filtrierten und veränderten Nahrungsstoffe beruhen. Wenn wir das ins Auge fassen, so wird uns das Blut erst recht bedeutungsvoll als «ein ganz besonderer Saft» erscheinen, kehrt es doch auf der einen Seite seine Wesenheit dem niedersten, untersten uns bekannten Reiche zu und zeigt sich als eine Materie, die fähig ist, äußere chemische Prozesse auszuführen, um dadurch ein Werkzeug sein zu können für das Ich. Auf der anderen Seite ist das Blut jene Substanz, die am geschütztesten ist, um innerliche Prozesse auszuführen, die sonst nirgends ausgeführt werden können, weil alle übrigen Organprozesse dazu als Voraussetzung notwendig sind.
Die feinsten, die höchsten Prozesse, die angeregt werden aus den Tiefen unseres Organismus, verbinden sich in unserem Blut mit physikalisch-chemischen Prozessen, wie wir sie überall in der Welt vor Augen haben. In keiner anderen Substanz trifft so unmittelbar die physisch-sinnliche materielle Welt mit einer anderen, inneren Welt zusammen, die voraussetzt das Dasein, die Tätigkeit von übersinnlichen Kraftsystemen, wie in unserer Blutsubstanz. Das tritt in keiner anderen Substanz so zutage wie in dem Blut, das unseren Organismus durchfließt. Dieses Blut ist in der Tat etwas, worin sich das Niederste, das der Mensch um sich herum schauen kann, zusammenfügt mit dem Höchsten, das sich in seiner Natur organisch ausbilden kann. Daher wird es uns wohl klar sein, daß wir in bezug auf diese im Blut sich abspielenden komplizierten Vorgänge etwas vor uns haben, das, wenn es etwas unregelmäßig wird oder Störungen eintreten, in einem hohen Maße Unregelmäßigkeiten in unserem Gesamtorganismus hervorrufen muß. Und daß wir da, wo solche Unregelmäßigkeiten sich zeigen, immer überlegen müssen, wie diese entstanden sind. Es wird schwierig sein, auseinanderzuhalten, ob wir diese Unregelmäßigkeiten im einzelnen Falle solchen Prozessen zuzuschreiben haben, die nach dem Muster physischer chemischer Prozesse verlaufen, oder ob sie anderen Prozessen des Blutes entsprechen. Wenn die Unregelmäßigkeiten verlaufen nach dem Muster physisch-chemischer Prozesse, dann müssen wir uns klar sein, daß ihnen begegnet werden muß von der Seite des Bewußtseins her, und zwar in dem Sinne, wie das Bewußtsein mit dem physischen Plan zusammenhängt. Hier eröffnet sich ein therapeutisches Gebiet, dessen Charakteristisches ist, darauf zu achten, ob gewisse Unregelmäßigkeiten zusammenhängen mit solchen Prozessen, die wir als physisch-chemische bezeichnen können. Bei dieser Voraussetzung ist es günstig, einzugreifen durch äußere Impressionen, durch entsprechende Regelung der äußeren Eindrücke, welche diese physisch-chemischen Prozesse hervorrufen können. Damit sind weniger seelisch-geistige Impressionen gemeint, dagegen namentlich alles dasjenige, was wir bewirken können durch eine Regelung des Atmungsprozesses und durch Überwachung der Prozesse der Wechselwirkung des inneren ÖOrganismus mit der Außenwelt durch die Haut.
Dann können wir aber auch von der anderen Seite her im Blut die feinsten organischen Vorgänge feststellen, und wir werden uns klar sein müssen, daß wir darin sozusagen die dritte Stufe der Verfeinerung unserer vorverarbeiteten Nahrungsstoffe zu sehen haben. Wenn im Blutorganismus jene feinen Prozesse der Salzbildung, der Quellbarkeit, der Wärme hervorgerufen werden durch äußere Vorgänge, also von außen in ihrem chemischen Verlauf bestimmt werden, so dürfen wir auf der anderen Seite fragen, wodurch die Prozesse im Blut von der inneren Seite her bestimmt werden. Wir müssen da unterscheiden zwischen der Aufgabe, die das Blut hat, und der Tatsache, daß es so ernährt werden muß wie jedes andere Organ auch. Zugleich müssen wir es auch als das Organ erkennen, das auf der höchsten Stufe der organischen Tätigkeit steht. Es kommt hier dasjenige in Betracht, was wir als die innerliche Stütze des menschlichen Lebens bezeichnen können. Das Blut muß vor allen Dingen davor geschützt werden, daß die äußere Welt auf dem Wege der Nahrungsstoffe unmittelbar in das Blut hineinwirkt, es wird sonst seine Tätigkeit als Werkzeug unseres Denkens unterbunden, es wird der Vorgang gestört, den wir als einen Prozeß der Salzablagerung früher bezeichnet haben. Dieser Schutz muß vom Blute selbst ausgehen; es muß imstande sein, nach der geistigen Seite hin gerichtet gleichsam ein geistiges Knochensystem aufzubauen durch die sich täglich wiederholenden Salzablagerungsprozesse. Das ist eine Aufgabe des Blutes, die es unterscheidet von anderen Organen. Von den anderen Organen des menschlichen Organismus erhält es dabei am wenigsten Unterstützung. Am wenigsten spielen die anderen Organe in diesen Salzbildungsprozeß des Blutes herein, so daß das Blut in bezug auf die durch das Denken bedingten Prozesse am meisten verinnerlicht ist, wie Ja in der Tat unsere Gedanken das Innerlichste sind, was wir haben. Mit unseren Gefühlen stehen wir an der Grenze von außen und innen, und mit seinen Willensimpulsen strömt der Mensch so stark nach außen, daß er sich unter Umständen gar nicht wiedererkennt. In seinem Denken wird sich der Mensch immer wiedererkennen, aber in seinen Willensimpulsen nicht. Daß es nicht so klar ist, wie die Willensimpulse entspringen, das können Sie schon daraus sehen, daß in bezug auf Freiheit und Unfreiheit des menschlichen Willens so viel in der Welt gestritten wird. In unserem Denken haben wir also das Innerlichste dessen, was das Blut als Werkzeug des Ich zu verrichten hat. Und weil nun der Prozeß der Salzablagerung am meisten verinnerlicht ist und auch am meisten geschützt sein muß, so kann durch Unregelmäßigkeiten oder Abnormitäten des Blutes auch diese Tätigkeit des Blutes am meisten behindert werden. Und wenn wir merken, daß das Blut so behindert ist, daß es nach dieser Richtung hin seine Tätigkeiten nicht mehr zeigt, so müssen wir uns darüber klar sein, daß es angeregt werden muß zu einer regelmäßigen Tätigkeit, wenn sein Eigenleben unter eine gewisse Grenze heruntergesunken ist.
Es kann aber auch der andere Fall eintreten, daß die innere Regsamkeit des Blutes über ein gewisses Maß hinausgeht, daß dieses Eigenleben stürmischer wird. Das ist der weitaus wichtigere Fall, weil er bei Erkrankungen viel häufiger vorkommt. In den seltensten Fällen haben wir es mit dem Entgegengesetzten zu tun. Meist haben wir es damit zu tun, daß die Tätigkeit der sonst geschützten inneren Organe zu stark angeregt wird und in gleichem Sinne auf das Blutsystem wirkt. Wenn sich das Blut so zeigt, daß es übermäßig nach der Richtung der Willenstätigkeit sich entfalten will, dann muß diesem Drang therapeutisch entgegengewirkt werden. Das können wir tun durch die Zuführung von solchen Substanzen, die zur normalen Salzbildung, zur normalen Salzablagerung im Sinne von seelischgedanklichen Prozessen führen. Das führt uns dazu einzusehen, daß ein gewisses System hineingebracht werden kann in die Art, wie wir solchen Unregelmäßigkeiten unseres Organismus entgegenwirken können. Es kann hier natürlich nur darauf hingewiesen werden, eine genauere Angabe würde über die Grenzen dieses Vortragszyklus hinausgehen.
Wie wir Erkrankungen einer zu großen Regsamkeit im Blutsystem zuschreiben mußten, so können wir uns auch fragen, wie wir den Organen unserer inneren astralischen Welt, unseres inneren Weltsystems, Milz, Leber, Galle und so weiter, beikommen können, wenn sie in ihrer Tätigkeit in einer zu großen inneren Regsamkeit sind. Da müssen wir uns vor allen Dingen vor die Seele führen, daß diese Organe ja bestimmt sind, heraufzuwirken bis zur Blutzirkulation, daß sie die Nahrungsstoffe so zu übernehmen haben, wie sie vom Verdauungskanal zugeführt werden, und diese hinzuleiten haben in umgewandelter Regsamkeit bis zum Blut, daß sie also die Vermittler zwischen diesen beiden Systemen sind. Wie das Blutsystem sich als Werkzeug erweist der größten inneren Regsamkeit, des bewußten denkerischen Lebens, so wird es auch zu einer Tätigkeit angeregt, die sich als zusammenhängend zeigt mit unserem Gefühlsleben, das wir schon beschrieben haben als Prozeß des inneren Verdichtens, des inneren Quellens. Hier wird das Blut — abgesehen von äußeren Einwirkungen — angeregt von der Tätigkeit der inneren Weltsysteme, die in ihrer charakteristischen Eigenart ihre Wirkungen in das Blut hineinstrahlen können. Wir haben hier auf eine Tätigkeit im Blut hingewiesen, die schon über das Eigenleben des Blutes hinausgehen, deren Ursache aber dem inneren Weltsystem angehört. Wir können nun die Frage aufwerfen: Können nicht auch diese Organe — Leber, Galle, Milz, Nieren, Lunge, Herz — eine zu große Regsamkeit, ein überquellendes Leben und damit eine unregelmäßige Einwirkung auf das Blut entwickeln? Und wenn sie das tun, wie können wir — in ähnlicher Weise wie beim Blut — die zu große Regsamkeit dieser Organe therapeutisch paralysieren? Da müssen wir — da diese Organe in direktem Zusammenhang stehen mit dem kosmischen Astralsystem — solche Stoffe zuführen, die die Regsamkeit des kosmischen Lebens entfalten. So wie wir durch Zuführen von salzhaltigen Stoffen die innere übertriebene Regsamkeit des Blutes verhindern können, so können wir die krankhafte Regsamkeit der inneren Organe abdämpfen und ihr entgegenwirken, indem wir Stoffe zuführen, deren Energie derjenigen der betreffenden Organe entspricht und die geeignet sind, sie wieder in Zusammenklang zu bringen mit der allgemeinen Gesetzmäßigkeit.
Für uns entsteht also jetzt die Frage: Wie können wir auf diese Organe einwirken? Wie können wir den Unregelmäßigkeiten der einzelnen Organsysteme und auch dem Verdauungssystem beikommen? Damit stellt sich die Frage überhaupt: Wie stellt sich uns ein Krankheitsbild im okkult-physiologischen Sinne dar, und wie sind die Krankheitserscheinungen zu heilen? - Wir werden morgen darauf zu antworten haben und dabei auch Rücksicht nehmen zum Beispiel auf das Muskelsystem. Unsere Betrachtungen werden darin ausklingen, daß wir zeigen, wie das, was als bewundernswerter fertiger Organismus uns entgegentritt, sich als werdender Organismus im Keimesleben deutlich ankündigt. Dann wird sich uns ganz von selbst ergeben, wie sich die übersinnlichen Glieder beteiligen an der menschlichen Organisation.
Seventh Lecture
In the course of these lectures, we have gained the impression that the various organ systems and structures of the human organism participate in the overall process of this human organism in the most diverse ways. We have been able to point out various things in this direction and have already felt compelled in the course of the previous lectures to provisionally assign the activities that work in the various organ systems to higher, supersensible members of the human organization. For example, we had to say that what we call the human ego is intimately connected with the human blood circulation, so that we could refer to the blood as an instrument of the human ego. We have also been able to assign what we call conscious life to the nervous system. But we have also shown how a special part of the nervous system—the sympathetic nervous system—has, in a certain sense, a task opposite to that of the other part of the nervous system, a task which consists in holding back, so to speak, everything that takes place in the depths of the human organism, everything that is brought about by the activity of the inner world system, so that in a normal physical condition it does not rise up to the horizon of the ego, that is, to the level of daily consciousness. Yesterday we also attempted to recognize, at least approximately, that what is most hidden from human conscious life is what is built up in the solid skeleton; but we had to emphasize how, even in this solid skeleton, there must be something essential at work that ultimately enables the human being to develop the organ of his conscious ego life, the blood circulation. We can also say that the incorporation of the human skeletal system means for the entire human organism that it can take on a human form at all and that everything that goes on within the processes taking place in the solid skeletal system is kept below the threshold of consciousness. In the human organization, we are always dealing with something similar, namely — and let us be clear on this point — that what is within this human organization is, as it were, protected from the influences that are at work in our surroundings and in the greater world of the cosmos. We have said that the members of the inner world system, those seven organs that in a sense mirror the outer planetary system within us — especially the spleen — hold back the outer laws of what we take in as food, freeing us, as it were, from these laws, and that the nutrients are thus taken into the human organism in such a way that they are filtered, so that they do not enter the human organism in such a form that they can operate within it according to their own laws and their own activity. In the crudest way, I might say, we have already given this protection of inner processes against external influences in the form of blood warmth for humans and higher animals. This blood warmth, which lies within narrow temperature limits, is maintained by an inner law and is independent of the heat processes of the macrocosm, the great world around us. Here you have a very clear example of a kind of fundamental phenomenon in this constancy of blood warmth. So we must always point out that one of the most essential aspects of the inner organization of the human being is that a limited essence is closed off from the macrocosm and develops its own activities.
Now we will do well today to gain a deeper understanding of the human organism by approaching it from a slightly different angle and taking a brief look at conscious life. We already know from previous lectures how the conscious life of the human being makes use of the tools of the blood and the nervous system, but we have not yet been able to go into the finer processes. What I am about to say is something that is likely to shock the outer world, the science commonly accepted today — let us be quite frank about that — to a high degree. But anyone who stands firmly on the ground of genuine, true occultism will tell you that the tendency of science is such that, within a few decades, even those things that we can only say today on the basis of occult observations will be confirmed and recognized. If, instead of such a short series of lectures, I could speak here for half a year about these things, it would be possible to bring forth from the results of present-day science everything that is suitable for proving, even outwardly, what is to be said in today's lecture. But I must leave some things to your own good will and the abilities of my esteemed listeners. It is possible everywhere to seek paths to external science which, if they proceed not from theoretical prejudices but from facts, can already find confirmation everywhere for what is said in the field of occultism. I ask you to take all these remarks in this sense.
If we start from our conscious life, especially if we consider the relationship of our conscious soul life to our organism, it is first necessary to take into account everything that we call our thinking activity in the most comprehensive sense. We need not go into subtle logical or psychological distinctions here; we need only stand before our soul and realize that we are dealing with the thinking life of the human being, with the feeling life and with the will life of the human being.
Now, among those who stand on the ground of true occultism, you will never find any contradiction when it is said that through all such processes that take place in our soul life in our waking consciousness and that fall under the categories of thinking, feeling, or volitional impulses, truly material processes—whether animated or otherwise—are brought about in the organism, so that we can find the corresponding material processes in our organism for everything that goes on in our soul. This is of the utmost interest. For only in our time, thanks to certain tendencies that are only now emerging in science, will it be possible in the coming decades to really discover these correspondences between soul processes and physiological processes in the organism and to confirm what has been gained from occultism.
Every thought process corresponds to a process in our organism, as does every emotional process and every process that must be described as an expression of the will. We could say, as it were, that when something happens in our soul life, a wave is set in motion that propagates down into the physical organism. Let us first take the process of thinking. It is best to consider a thought process that, like purely mathematical thinking or similar objective thinking, leaves our feelings and will uninfluenced. Let us first consider such thought processes, which are thought processes “in their purest form.” What happens in our organism when such thought processes take place in our soul life? Every time we think, every time we form thoughts, a process takes place in our organism that we can compare—I am not saying this as an analogy, but as a fact; the comparison is intended to lead us to facts—that we can compare with the process of crystallization. If we have a glass of water that has been heated to a certain temperature and have dissolved some salt, rock salt for example, in it, and then cool the water, causing the dissolved salt to crystallize, the opposite process to dissolution takes place. When the salt is completely dissolved, the water is transparent. But when the water is cooled again and the process opposite to dissolution takes place in the water, the salt crystallizes out of the water again; a salt reduction occurs, a salt deposit in the water. The process is therefore such that we see: When we cool the previously warm water, a solid forms; a solid is deposited in the liquid, a salt deposit. As I said, I have assumed that the occult results may initially shock those who, in a purely philistine sense, are only willing to admit facts that have been recorded by science.
A completely identical process takes place in our organism when we think. It is the process of thinking corresponding to a process of salt deposition, which originates from an effect of our blood and has an irritating effect on our nervous system, an organic process, therefore, which takes place at the boundary between our blood and our nervous system. And just as we can observe the crystallization of salt when we look at the water in the glass, so we can see, when we observe a person who is in a satisfactory position to think, how such a process actually takes place—very precisely perceptible to the clairvoyant eye. In this way, we have placed the physical correlate of the thought process before our soul.
Let us now ask ourselves: How does the corresponding process appear in feeling? — In feeling, we are not dealing with the deposition of salts that solidify, i.e., not with a reverse dissolution process, but rather with subtle processes taking place in our organism that occur in much the same way as when a liquid becomes semi-solid. Think of it this way: a liquid becomes semi-solid, like liquid egg white, it coagulates to the consistency of thickened egg white; in other words, a liquid becomes solid. While in the thought process we are dealing with the extraction of a solid, salt-like substance from a liquid that is deposited, in the emotional process we are dealing with the transition of certain particles in the blood from a more liquid state to a denser state. The substance itself is brought into a denser state through a kind of coagulation. To the clairvoyant eye, this appears as the formation of small flakes, just as in a glass containing a certain liquid, certain processes can cause internal flake formation, a separation of small droplets from a liquid substance.
If we now move on to what we can call our will impulses, the physical correlate for this is again different. This is even easier to grasp, because we are now coming to the side where things become a little more obvious. The physical process corresponding to our will impulses is a kind of heating process that causes temperature increases in the organism, a kind of heating of the organism in a certain sense. Since this heating is closely related to the entire pulsation of the blood, we can say that the will impulses are connected with an increase in the temperature of the blood. This does not require much; if one has even a modicum of sense for real observation, one can already observe in the animal organism that the impulses of the will have their physical correlate in the warming of the blood.
In this way, we can characterize to some extent the physical correlates that occur in inner, mental processes. What I have just characterized is, of course, not something that occurs in a very crude form, but rather extremely fine, minute processes, processes of a subtlety that we cannot usually even imagine. But with the exception of the heating processes, these processes take place in such a way that, in relation to everything we know of similar processes in the external physical world, they display an enormous delicacy. All these are processes that the organism carries out through its entire forces when the ego is active, with the help of the instrument of blood. From salt deposition to swelling and heating, these processes take place in such a way that the entire organism is affected or, for example in the case of the thinking process, mainly a part of our organism, the brain and spinal cord system. These processes, which are the consequences of the influence of the soul processes, are distributed in the most diverse ways in the human organism. When one gradually comes to know these things as facts, one must admit that what we call thoughts, feelings, or impulses of the will are real forces that have real effects within the physical organism and express themselves in real effects. We must speak purely from occult observation of a real effect of the soul on the human organism. These real effects on the human organism will gradually be revealed in the coming decades of science. These subtle processes in the organism will become accessible to the more careful and subtle methods of scientific investigation; and then the resistance that today arises not from the facts that science has investigated, but from certain prejudiced theories which are linked to these facts, against assertions that can be made from occult knowledge.
Now we have pointed out that what we understand as a conscious activity of the ego is, in essence, only a part of the human being, and that beneath the threshold of what penetrates our consciousness in this way, processes take place that lie below the threshold of consciousness and are, as it were, kept away from our consciousness by the sympathetic nervous system. We have been able to point out from various sides how what we carry within us in this unconscious state is also connected in a certain way with our ego. We have said that the most unconscious part of us, our skeletal system, is organized from the outset in such a way that it can provide the very foundation for the instrument of the conscious ego. Thus, an unconscious ego organization grows out of the unconscious and develops toward the conscious ego organization. For us, the human being is divided into two parts, as it were: on the one hand, the conscious ego organization works within the human being, and on the other hand, the unconscious ego organization works within the human being (see drawing on p. 136). In this connection, we have seen that the blood system and the bone system form a certain contrast to the conscious ego organization, appearing as opposite poles. While the blood, in its inner activity, follows the ego's activity as a pliable tool, the other pole, the skeletal system, withdraws itself from the activity of the ego in such a way that the ego has no consciousness of anything that happens in the skeletal system, that is, all processes taking place in the skeletal system occur completely beneath the surface of the actual conscious ego events. These are processes that correspond to our ego activity, but they are as dead as our blood processes are alive; they are thus basically part of those processes that remain unconscious to the ego, which only gradually rise from the unconscious to consciousness.

If we take a close look at the bone system in its overall function in the human organism, we cannot fail to notice that it eludes all conscious life, and indeed more than any other organ system. But if we now move from the skeletal system to the organ systems, which we have called the inner world system of the human being, to the liver-gallbladder-spleen system, to the lung-heart system, and so on, we must say, in accordance with what has been said in previous lectures on this subject: The processes within these systems are also largely hidden from our consciousness, but not quite as much as the processes in our skeletal system. We need to think about our skeletal system much less and pay less attention to it than to the organs just mentioned. Some of these organs even reveal their functions to humans very clearly as something that protrudes from the unconscious. It is somewhat like an object floating in the sea that partially rises and becomes visible above the surface like an island. In the same way, some of what goes on in the heart rises into consciousness. You know from experience how particularly hypochondriacal natures—to their own detriment, of course—feel something of what is going on in their internal organs, although they are aware of it quite differently from how it is going on inside, but they do feel it nonetheless. I am not talking now about what it is like when a certain degree of disease has already set in in the organs. When one becomes ill, one becomes conscious of one's organs; but there is a real cause that causes the effects of the inner world systems to rise up into consciousness. Rather, I am talking about the fact that it does not take long to reach the limit that a healthy person has in relation to illness. Unfortunately, this boundary shifts quite often. What is often referred to as illness can certainly be regarded as a lesser or greater degree of inner processes rising up into consciousness. We must therefore always investigate the causes of various illnesses by asking ourselves: Do the causes of pain lie in organ diseases, or must we look elsewhere? We know that we are protected from becoming conscious of what is happening down there in the organism by the sympathetic nervous system.
When we see something in the skeletal system that builds up the human being in such a way that the blood system can be a tool for the ego in the appropriate manner, we must be clear, according to what has just been said, that the other organ systems also grow in a certain way toward the conscious life of the human being, which is ultimately to unfold like a flower. We must be clear that all these organs, even though they are not permeated by fully conscious life, already contain what grows toward our conscious soul life, just as we have seen that our skeletal system grows toward the ego life.
We must now ask ourselves the question: To what degree does this inner system, which we have called an inner world system, grow toward the conscious soul life of the human being? If we consider, on the one hand, that we have in the skeletal system the most solid support in our physical body, which gives the blood system its arrangement so that it works in the right places to develop as an instrument of the ego, then we must also say, on the other hand, that the skeletal system supports and holds in the right position those organs which we previously called inner world systems. For what happens to the blood also benefits these organs. If you consider all these organ systems, you will notice that you cannot discover anything in their arrangement that is as essential and intimately connected with the outer form of the human being as the skeletal system. It is the foundation of the human form, and what builds itself up and layers itself around the skeletal system can only do so because the skeletal system provides the basic form. Even the skin, as the outer boundary of the body, is, as it were, preformed by the entire structure of the skeletal system. Goethe expressed this beautifully, not only from an aesthetic but also from a scientific point of view: “There is nothing in the skin that is not in the bones.” This means that the outer structure of the skin expresses what has already been preformed by the skeletal system. We cannot say the same about our inner world system. On the other hand, however, it is precisely the emergence of the effects of the inner world system at lower levels of consciousness that shows that this inner world system has something to do with our astral body, for the astral body is the carrier of consciousness. We must therefore say that although this inner world system cannot appear to us as an expression of the subconscious ego, the form-giving ego lying in deep foundations, it can appear to us as something that is so integrated into us through the entire world process as an expression of the environment that it has a similar relationship to our astral body as the bone system provides the foundation for the human form that encompasses the ego. We can therefore say: We have already preformed the human ego in the skeletal system, deep down in the subconscious, and in what we call our inner world system we have preformed what we call our astral body.
Now, because it lies beneath consciousness, this inner world system in its entire organization does not originate from conscious soul life; it is inserted into our organism from the macrocosm. Thus, something that we can call a cosmic astral is inserted into the human being in such a way that it expresses itself as our inner world system. And in our skeletal system, we have again incorporated into our organism something from our environment, from the great world system, and because this is connected with the entire form of our physical organism, we must say: This skeletal system is actually the foundation for our ego in our physical body, because it is a macrocosmic or, simply put, a cosmic system that makes us into these physically formed human beings. In addition to this skeletal system, a macrocosmic astral world system is stored within us as our inner world system. Insofar as our ego appears as a conscious ego, it has the blood system as its tool; insofar as our ego is preformed as form and shape, it is based on a cosmic force system that pushes toward solid formation and finds its densest expression in our skeletal system.
Let us consider the matter from another point of view. We now know that everything we have described as conscious thought activity brought about by the ego is expressed through a kind of fine salt deposit in the blood. Conscious thinking thus reveals itself through a kind of inner salt deposit. We can therefore expect that where our skeletal system is preformed out of the cosmic, so that the organism can form the material support for the human being as a thinking being, we should also find the physical process of salt deposition. We should therefore be able to find salt deposits in the bone system; and indeed, bones consist partly of phosphoric acid and carbonic acid calcium, i.e., deposited calcium salts.
Here, too, we have the two opposing poles. Through our thinking activity, thought processes are what make us into solid beings internally. In a certain sense, our thoughts are our inner skeleton. Human beings have certain sharply defined thoughts; our feelings, on the other hand, are indefinite, fluctuating, and more or less different in each individual. Thoughts form fixed inclusions in the emotional system. While these fixed inclusions express themselves in conscious life through a kind of active, mobile salt deposition process in the blood, what the ego prepares is expressed in the skeletal system in such a way that the macrocosm forms our skeletal system so that it is largely made up of deposited salts. These are now the resting element in us, the other, opposite pole to the processes of inner activity that take place in the salt deposition processes in the blood. Thus, as human beings, we are made thinkers from two sides in our organization: on the one hand, unconsciously, through the formation of our skeletal system; on the other hand, consciously, in that we consciously carry out the same processes — following the pattern of our skeletal formation process — which manifest themselves in the organism as salt deposition processes, which we can say are internally active. The salts formed during thinking must be dissolved and removed immediately through sleep, otherwise they would cause something like decomposition processes, dissolution processes in the organism. We must therefore see a real process of destruction in thinking. And through beneficial sleep, a process of regression is brought about which causes the blood to become free of salt deposits again, so that we can develop conscious thoughts anew in our waking daily life.
But it is not enough to simply say that thinking is a process of salt formation, because if people do not understand this correctly, someone might say that spiritual science is claiming the most ridiculous things.
Let us now go further. We can imagine that between these two extreme poles of salt formation, all other processes in the human organism take place, essentially those we have already pointed out. Just as we have active salt formation processes through thinking, which have their opposite pole in the salt formation process in the bones, which has come to rest to a certain degree, so we also have a counterpole to what we have described as the internal swelling process, as coagulation, as flocculation, as something similar to protein-like inclusions that arise under the influence of our emotional life, as an external expression of our emotional life. This opposite pole manifests itself in what are more internal processes of our organism and participates in such unconscious swelling, in a poeticization of substances that form and are deposited as an effect of the macrocosmic astral system. It is the bone glue that participates in the bone formation process and is incorporated into the other bone substances. This is the other pole of the swelling process, as opposed to what arises as a physical correlate through our feelings.
Our impulses of will are expressed organically in a process of heat, in an inner warming process. Connections that form and that we can describe as products of internal combustion processes, as internal oxidation processes, can be found throughout our entire organism. And insofar as they occur below the threshold of consciousness and have nothing to do with conscious life, they belong to the other side, the opposite pole, which is closed off from anything that can influence conscious life. This means that humans are internally protected from disturbances by part of their organism, so that processes of the utmost delicacy, initiated by the soul life, can take place within it.
As we have learned, physiological processes such as salt formation, swelling, and heat generation take place in our organism that follow our conscious life, and processes that take place outside our conscious life in such a way that they first provide the basis for what is being prepared in the human organism so that conscious life can unfold at all. Thus, our entire organism is a tangled web of processes that we must describe as belonging to our conscious life and those that we must describe as belonging to our unconscious life. It is an extraordinarily significant fact that our organism really represents something like a unity of two polarities: that processes of the same kind take place in such a way that they protrude into the organism from the macrocosm and, as it were, take place in the coarser realm, and on the other hand, there are processes which, as consequences of the conscious life of the human being, can take place in the finer realm.
Now, in today's finished organism, the situation is such that all these processes interact with each other and that, as the organism stands before us, we cannot actually separate them from each other in such a way that we can designate certain boundaries everywhere; one process plays into the other. You need only consider the blood system, the most active and finest element. In the blood, you see both the stimulus for the processes of salt deposition and the processes of coagulation of a liquid substance, as well as the processes of warming. We find these processes closely related to each other in a similar way in other organ systems. When we take food from outside into our digestive tract, for example, this food still has what I have called its external activity. They undergo a first stage of sifting by being taken in through the mouth and prepared for the digestive process in the stomach through the chewing process; in a further stage, they are processed by the organs that we have called the inner world system, and finally they are brought to the point where they can nourish the finest instrument of the human organism, the blood. Having thus indicated, in a certain sense, a series of stages in the sifting of food substances through the internal organ systems, we can now easily imagine that the most refined system, the blood system, must take in the most refined food activities, so to speak, and that what reaches the blood contains very little of the nutrients' own activity that they had when they were absorbed. When the substances are absorbed, they still retain a good part of their own nature and laws. They had to give these up in the stomach and the other organ systems they passed through, and to the extent that they are now in the blood, they have become something completely new. Therefore, blood is also the organ that is most protected against impressions from the outside world, the organ whose processes are most independent of the outside world. That is one side of the coin; but we have already shown in detail that blood has two sides, that it is exposed to influences from both sides, like a board. On the one hand, blood is carried to those organs in the deeper regions of the human organism where all processes are held back and repelled by the sympathetic nervous system so that they do not reach consciousness. Now, blood must also turn to the other side, to the experiences of conscious soul life. It must not only take in the unconscious processes, but the conscious I must also impress itself upon the blood. Our conscious soul activities must be able to transform themselves until they reach the blood, so that in this blood they become an expression of what we have around us. What do we have around us? The physical-sensory world; for that which is incorporated into the plant world—the etheric body—does not exist for normal consciousness. For bright daytime consciousness, human beings belong only to the physical world; the world of life is invisible to us.
Thus we stand opposite the other side of the blood tablet of the physical-sensory world. The entire soul life, as it proceeds under the impressions of the physical-sensory world, as it is aroused to thoughts, as it is inflamed to feelings, as it is stimulated to impulses of the will, must be able to find its instrument in the blood system, insofar as it is conscious ego-life. All of this must be able to pulsate in the blood. What does this mean? It means nothing other than that we must not only have in our blood that which comes from nutrients after they have been highly filtered, deprived of their own activity, and protected from all macrocosmic laws, but that — so that the inscription on the blood tablet is also possible from the other side — there must also be something in the blood that is related to the physical-sensory, to the lifeless of the physical-sensory world. that is related to the physical-sensory, to the inanimate of the physical-sensory world. What constitutes life can only be recognized by ordinary consciousness through the combination of physical-sensory impressions; in its reality, it can only be recognized through the lowest supersensible member of the human being, through the etheric body.
Blood must therefore be related to the physical-sensory world as it is in itself. We will now see that something is incorporated into blood about which we can say: This is not the case in our blood, as if it were determined by processes that rise up from our being, from the depths of our organism, to the blood, whose laws are therefore adapted to ours, but rather it is as if it were incorporated into our blood through the effects of external macrocosmic laws and activities. We must have something in our blood that is and acts like immediate external processes, but which internally take place just as they do externally in the macrocosm, and thus do not lose their own laws. Physical, chemical, inorganic processes must therefore play a role in our blood; they are necessary so that our ego can participate in the physical world. We must therefore look for substances in the blood that can act in such a way that their physical character, their inherent laws, are preserved. We do indeed find this in the blood. In our red blood cells, we have something that clearly shows that it is just beginning to live and is at the point where it passes from life to lifelessness. On the other hand, we have incorporated into the blood a continuous warming process that can be compared to an external combustion process, where the oxidation process gives rise to new possibilities of life. We have thus incorporated into the blood that which makes human beings physical, sensory beings.
Thus, even in the organization of blood, we see how significant physical and chemical research can be illuminated by what can be communicated from occult observation, and how this makes what is immediately apparent to the external view understandable.
We can therefore say that in the human organism, in the blood, there are processes that are stimulated by the influence of the external world and are of a physical-sensory nature; but we also have processes in the blood that originate from within and are based on the storage of food substances that have been filtered and transformed to the utmost degree. When we consider this, blood appears even more significant as a “very special fluid,” since on the one hand its essence belongs to the lowest, most basic realm known to us and it manifests itself as a substance capable of carrying out external chemical processes, thereby enabling it to be a tool for the ego. On the other hand, blood is the substance that is most protected for carrying out internal processes that cannot be carried out anywhere else, because all other organ processes are necessary for this.
The finest, highest processes that are stimulated from the depths of our organism combine in our blood with physical-chemical processes such as we see everywhere in the world. In no other substance does the physical-sensory material world come into such direct contact with another, inner world that presupposes the existence and activity of supersensible force systems as in our blood substance. This is evident in no other substance as it is in the blood that flows through our organism. This blood is indeed something in which the lowest, which man can see around him, merges with the highest, which can develop organically in his nature. It will therefore be clear to us that, with regard to these complex processes taking place in the blood, we are dealing with something which, if it becomes irregular or if disturbances occur, must cause a high degree of irregularity in our entire organism. And that where such irregularities appear, we must always consider how they arose. It will be difficult to distinguish whether, in individual cases, these irregularities are attributable to processes that follow the pattern of physical-chemical processes, or whether they correspond to other processes of the blood. If the irregularities follow the pattern of physical-chemical processes, then we must be clear that they must be countered from the side of consciousness, in the sense that consciousness is connected with the physical plane. This opens up a therapeutic field whose characteristic feature is to pay attention to whether certain irregularities are connected with processes that we can describe as physical-chemical. Given this prerequisite, it is beneficial to intervene through external impressions, through appropriate regulation of the external impressions that can trigger these physical-chemical processes. This refers less to mental and spiritual impressions and more to everything we can achieve by regulating the respiratory process and monitoring the processes of interaction between the inner organism and the outside world through the skin.
But then we can also observe the finest organic processes in the blood from the other side, and we must realize that we are seeing, so to speak, the third stage of refinement of our pre-processed nutrients. If those subtle processes of salt formation, swelling, and heat generation in the blood organism are caused by external processes, i.e., determined from outside in their chemical course, then we may ask, on the other hand, what determines the processes in the blood from within. We must distinguish between the task of the blood and the fact that it must be nourished like any other organ. At the same time, we must also recognize it as the organ that stands at the highest level of organic activity. What we can call the inner support of human life comes into consideration here. Above all, the blood must be protected from the external world acting directly on it through nutrients, otherwise its activity as an instrument of our thinking will be inhibited and the process we previously described as salt deposition will be disrupted. This protection must come from the blood itself; it must be able to build up, as it were, a spiritual bone system directed toward the spiritual side through the daily repeating processes of salt deposition. This is a task of the blood that distinguishes it from other organs. It receives the least support from the other organs of the human organism. The other organs play the least role in this salt formation process of the blood, so that the blood is most internalized in relation to the processes conditioned by thinking, just as our thoughts are indeed the most internal thing we have. With our feelings, we stand at the boundary between the external and the internal, and with his impulses of will, man flows so strongly outward that under certain circumstances he does not even recognize himself. In his thinking, man will always recognize himself, but not in his impulses of will. That it is not so clear how the impulses of will arise can be seen from the fact that there is so much controversy in the world about the freedom and lack of freedom of the human will. In our thinking, therefore, we have the innermost part of what the blood has to accomplish as the tool of the I. And because the process of salt deposition is most internalized and must also be most protected, irregularities or abnormalities in the blood can also hinder this activity of the blood the most. And when we notice that the blood is so impeded that it no longer shows its activities in this direction, we must be clear that it must be stimulated to regular activity if its own life has fallen below a certain limit.
However, the opposite case can also occur, in which the internal activity of the blood exceeds a certain level and this inner life becomes more turbulent. This is by far the more important case because it occurs much more frequently in diseases. In the rarest of cases do we encounter the opposite. Mostly we are dealing with a situation in which the activity of the otherwise protected internal organs is stimulated too strongly and has the same effect on the blood system. If the blood shows signs of wanting to develop excessively in the direction of volitional activity, then this urge must be counteracted therapeutically. We can do this by administering substances that lead to normal salt formation and normal salt deposition in the sense of mental and emotional processes. This leads us to realize that a certain system can be introduced into the way we counteract such irregularities in our organism. Of course, only a general indication can be given here; more detailed information would go beyond the scope of this lecture series.
Just as we had to attribute illnesses to excessive activity in the blood system, we can also ask ourselves how we can help the organs of our inner astral world, our inner world system, the spleen, liver, gallbladder, and so on, when they are too active. We must first of all bear in mind that these organs are designed to work their way up to the blood circulation, that they have to take up the nutrients as they are supplied by the digestive tract and convey them in a transformed state of activity to the blood, that they are therefore the mediators between these two systems. Just as the blood system proves to be the instrument of the greatest inner activity, of conscious, thinking life, so it is also stimulated to an activity that is connected with our emotional life, which we have already described as a process of inner condensation, of inner wellspring. Here, apart from external influences, the blood is stimulated by the activity of the inner world systems, which, in their characteristic nature, can radiate their effects into the blood. We have pointed out here an activity in the blood that goes beyond the life of the blood itself, but whose cause belongs to the inner world system. We can now ask the question: Can't these organs — liver, gallbladder, spleen, kidneys, lungs, heart — also develop excessive activity, an overflowing life, and thus an irregular effect on the blood? And if they do, how can we—in a similar way to the blood—therapeutically paralyze the excessive activity of these organs? Since these organs are directly connected to the cosmic astral system, we must supply substances that unfold the activity of cosmic life. Just as we can prevent excessive inner activity of the blood by supplying substances containing salt, we can dampen and counteract the pathological activity of the internal organs by supplying substances whose energy corresponds to that of the organs concerned and which are suitable for bringing them back into harmony with the general laws of nature.
This raises the question: How can we influence these organs? How can we address the irregularities of the individual organ systems and also the digestive system? This raises the fundamental question: How does a disease manifest itself in an occult-physiological sense, and how can the symptoms of the disease be healed? We will answer these questions tomorrow, taking into account, for example, the muscular system. Our considerations will conclude by showing how what appears to us as an admirable finished organism clearly announces itself as an organism in the making in the germ life. Then it will become clear to us how the supersensible members participate in the human organization.
