Lecture III
Rudolf Steiner: Good morning, gentlemen! You will have realized from all we've said that our earth in its present form is only the last remains of what was once essentially different. If we want to compare its earlier condition with anything, we can only compare it really—as you have seen—with what one has in an egg cell. Our earth today has a solid kernel of all sorts of minerals and metals. And we have the air around us, and in the air two substances which especially affect us-we could not live without them: oxygen and nitrogen. We can say therefore that in the earth we have a hard kernel of all kinds of substances, seventy to eighty of them, and around us the air-envelope containing mainly nitrogen and oxygen.
Nitrogen and oxygen, however, are only the main constituents. The air always contains other substances, though in very small quantities, such as carbon, hydrogen, sulphur, among others. But these are also the substances contained in the white of an egg, in the white of a hen's egg. Oxygen, nitrogen, hydrogen, carbon and sulphur! The difference is merely that in the egg white the sulphur, hydrogen and carbon are closely combined with the oxygen and nitrogen, while in the outer air they are present in a much looser way. So the same substances are in the air that are in the hen's egg. The same substances are present in a much smaller amount in the yolk, and we can therefore say that when it hardens, densifies, it becomes what the earth is. One must observe such things if one wants to know what the earth once looked like.
Today, however, things are done in quite a different way, and in order that your judgment of what I am telling you here may not be confused by what is commonly accepted, I would like to give you a small view of this general knowledge. It agrees perfectly with what I say if only one considers it in the right way.
People today do not think about things as we have done here in the last two lectures. They say: Here is the earth; it is made of mineral substance. This mineral earth is convenient to investigate, so let us examine first what lies on top, what we walk on. Then if we make quarries, if we make railway cuttings and open up the ground, we find there are certain layers or strata of earth. The uppermost layer is the one on which we walk. If we go somewhere or other into the depths, we find deeper-lying strata. But these strata are not always lying so nicely above one another that we can say: the one is always above the other.
When you really examine the earth, here you have one stratum [See drawing-red], it is curved over, not level; another stratum below is also curved [green]. And above them comes the stratum on which we walk [white]. Now, as long as we remain on foot on this side of a hill we find an upper layer that could become good arable land if we would use the right manuring methods and so on. But if we are building a railway we may have to remove certain strata and by making these cuttings we come into the depths of the earth. That has led to the discovery that strata are superimposed on one another, not level, but they have been jumbled up in all sorts of ways.
But these strata are sometimes very remarkable. People have asked how one can determine the age of the strata—which layer is older. Of course the most obvious answer is this: When the strata lie above one another, then the lowest is the oldest, the next above, younger, and the one at the very top the youngest of all. But, you see, that is not always the case. In some places it is so, but not everywhere. And one can show in the following way why it is not the case everywhere.
We are accustomed, as you know, in our civilized lands to bury our domestic animals when they die, so that they may not be injurious to people. But if the human race were not so far evolved, what would happen with the animals then? Wherever the animal died, there it would lie. Now at first it remains on the surface. But, as you know, when it rains the soil gets washed up and after a time part of the decaying creature is mingled with the soil thrown up by the rain. There it will remain, and after some time the whole animal is penetrated with earth by the rain or by water that flows down over a slope and then the rest of the earth goes over the animal. Now someone can come along and say: Heavens! The earth looks so uneven there, I must dig and have a look! He need not dig very far, just a little, and then he finds what is left of the skeleton, let us say, of a wild horse. Then he says: Well, now I'm walking on a stratum that only appeared later, the one below was formed when there were wild horses like that. And one can know that that is the next stratum, that the age in which this man lives was preceded by an age in which these horses lived.
You see, what that man does is what the geologists have been doing with all the strata of the earth, ever since the time when they could be reached by quarries, railway cuttings, excavations, and so on. One learns in geology to investigate quarries everywhere, with a hammer or some other instrument, in order to record what is exposed in the mountains through landslides or something similar. One goes hammering everywhere, makes various statements and then one finds in some stratum the so-called fossils. Then one can say: There are strata beneath the ground that contain animals quite different from those of today. Then one discovers in excavating the earth's strata what the animals were like that existed in other ages.
This is nothing so very special, for people often underestimate the time it takes for something like this to happen. People find today in southern regions churches or other buildings just standing there. The people come along, do some digging for some reason or other, and Heavens! there's something under this church that is hard; that's not earth. They dig down and find a pagan temple underneath! What had happened? A relatively short time ago this surface layer on which the church or building stands was not there at all. It was pushed up by man, perhaps with the help of nature-forces, and underneath there is the pagan temple. What was once above, is now below. Layer upon layer has in fact been piled up in the earth. And one must find out, not from the way the strata lie, but from the nature of the fossils, how these animals and the various plants have come into the strata.
Then, however, the following comes about: You find one layer of the earth [See drawing below, yellow], you find another [green]; you are able for some reason or other to excavate [arrow], and if you look merely at the stratification, then it seems as if what I have marked green were the lower layer and what I have marked yellow were the upper layer. You cannot get in here at all, you cannot excavate, there is no railway, no tunnel nor anything else by which one can get in. You make a note that the yellow is the upper stratum, the green the lower. But you must not decide immediately, you must first look for fossils.
Now one very frequently finds fossils in the upper stratum which are earlier, of fish, for example, strange fish-skeletons which are earlier. And perhaps below, one finds interesting mammal skeletons which are more recent. Now the fossils contradict the strata, up above appear the older, the earlier; below, the more recent, the younger. One must realize how that has happened. You see, it is because some sort of earthquake, some inner movement has flung what was below up above the top layer. It is the same as if I were to lay a chair on the table and the original position would be: here the chair-back and here the table-top, and then through an earthquake the table would be turned over the chair.
One can perceive in the most varied instances that there has been an inversion, a turning upside down. And one can come to the following conclusions as to when the inversion took place: It must have happened later than when all the animals were alive, it must have happened after the fossils were formed, otherwise they would lie differently.
One comes in this way not to judge the strata simply as they lie one above the other, but one must be able to see how they have changed their positions. The Alps, this mighty chain of mountains stretching from the Mediterranean Sea to the region of the Danube, this main mountain range in Switzerland, is not to be understood at all unless one can go into such things. For all the strata that were built up in the Alps have later been thoroughly jumbled up. There what was lowest often lies at the top, and what was at the top is lowest of all. One must first find out how all these shifts have taken place.
It is only when all this is taken into account that one can tell which are the oldest strata and which are the newest. Modern natural science, only going by the externals of research, then naturally says: Those strata are the oldest in which the remains of the very simplest animals and plants are found. Later on, animals and plants grew more complicated, and so we find the most complicated remains in the latest strata. In the oldest strata one finds fossils because the calcium or quartz structure of the animal has been preserved, while everything else has been dissolved. When one comes to the later strata the skeleton has been preserved.
Now there is another remarkable way in which fossils are formed. Sometimes this is very interesting. Picture that there once existed some simple type of ancient creature; it had a body, perhaps with tentacles in front. I am drawing it rather large; in the strata known to geology it will as a rule be smaller. Now this creature perishes lying on this piece of ground, and this particular soil does not penetrate and permeate the creature; it avoids, so to say, the acids in the body. Then something very remarkable occurs: the earth in which the animal lies approaches it from all sides and envelops it, and a hollow space is made in the shape of the animal. That has happened very frequently; such hollow spaces are formed, earth is shaped around the animal. But there is nothing inside; the soil has not been absorbed by the body, but round about, because the animal was scaly, a hollow space is formed. Later, the scales are dissolved and still later a brook winds through.
This then fills the hollow space with stony gravel, [green] and there within, a cast of the animal is finely modeled, by a quite different material. Such casts are particularly interesting, for there we don't have the animals themselves, but their casts.
However, you must not imagine that things are always so easy. Of present man, for instance, with his organism of soft substance, there is extraordinarily little left—nor of the higher animals. There are animals of which only the casts of their teeth have remained. One finds casts of the teeth of a kind of primeval shark which were formed in this way. One comes to realize that every animal has its own form of teeth and man has a different form. The dental formation is always in keeping with the whole structure of the creature. One must have the talent to imagine the appearance of the whole animal from the form of its teeth. So things are by no means simple.
But as one studies these strata one finds out how things really developed. And then it simply becomes clear that there was a time when such animals as we have now did not exist, when there were much, much simpler creatures, somewhat like our snails, mussels, and so on. But one has to know how much has remained of them. Let us imagine that the following could happen. Just suppose that a small boy who did not like to eat crab sneaked a crab from his parents' dinner-table and played with it. He is not caught and buries it in the garden. Now there is earth over it and the whole business is forgotten. Later the garden belongs to new owners; they dig about and in one place they see some funny little things looking like lime-shells. (You know about the so-called crab's eyes which are not eyes, but little lime-shells in the body of the crab.) Those are the only traces left.
Now one cannot say that those are fossils of some kind of animal; they are fossils of only part of the creature. Similarly in older strata, especially in the Alps, one finds some sort of fossil having that shell-like appearance. That is how they look; they no longer exist today but are found in the earlier strata. One must not suppose, however, that this had been the whole creature. One must assume that there was something around it that dissolved, and only a small piece of the animal is left.
Modern science goes into this very little. Why? Well, it simply says that in this mighty Alpine mass the layers have been mixed with one another, the lowest flung to the top, the uppermost to the lowest—that the strata show it. But can you imagine, gentlemen, that with the present earth-forces such massive mountains could be flung up in that way? The little that happens now on earth is by comparison a dancing through, one fleck lightly tossed on another—today that is all, a sort of dancing through!
If a man lived 720 years instead of seventy-two, he would experience in his old age that he was walking on ground a little higher than before. But we live too short a life. Just think if a fly that only lives from morning till evening were to relate what it experiences! Since it lives only in the summer, it would tell us of nothing but flowers, that there were always flowers. It would have no idea of what goes on in the winter; it would believe that each summer joined on to the one before. We human beings are certainly a little longer-lived than a one-day fly, but still we have a little of the fly nature with our seventy to seventy-two years! We see indeed little of what goes on. Even with the scanty forces prevailing today, there is no doubt that more happens than man usually sees. Yet, comparatively speaking, all that happens is that rivers flow along to the sea and leave alluvial soil behind. So a little soil is deposited, and this then reaches beyond the shores and the fields get a new stratum. That is comparatively little. When one considers how something like this great mountain mass of the Alps has been jolted and shaken through and through, it is obvious that the forces which are active today were active in quite a different way in earlier times.
But now we must try to picture how such a thing can happen. Take, for instance, an egg cell from some mammal. It looks at first quite simple, a nucleus in the center with an albuminous mass all around. Now suppose that the egg is fructified. When it is fructified, the nucleus changes into all sorts of little forms; it develops very strangely into a number of spirals that go up like tails. And then the moment these little coils arise, star-formed structures develop out of the mass. The whole mass comes into formation because there is life in it. What goes on there is very different from what goes on in our earth today. The upheavals and over-turnings that are taking place in the egg cell are the same as what once took place in the massive Alps!
What then is more natural than to say: Well, then the earth must once have been alive, or these convulsions of inverting and overthrusting could not possibly have occurred! The present form of the earth does in fact show us that in past ages when neither man nor higher animal existed, the earth itself was alive. This obliges us to say that the present dead earth has come forth from a living earth. Yet animals can only live on this present dead earth! Just think if the oxygen and nitrogen in the air had not separated off and had not condemned hydrogen, carbon and sulphur to an almost complete passivity: we would then have to breathe in something like egg white—for that was what surrounded the earth.
Now we could imagine—for anything can happen in this world!—that instead of our lungs, we had developed organs able to draw in an albuminous atmosphere like that. Today, of course, we can take it in as food through the mouth. Why could not a sort of lung-organ have evolved, up nearer to the mouth? Anything can originate in this world; any possible thing might come about—even though we would never guess at such changes from observing man's present body. But think, gentlemen—we look today into lifeless air. It has died. Formerly the albumen was living. The air has died because the sulphur, hydrogen and carbon have gone and the nitrogen and oxygen have therefore also perished. We gaze into light-filled air that has died, but this has allowed our eyes to be physical, as they are indeed physical. If everything in our surroundings were living, then our eyes would have to be living too. But if they were living, we would be unable to see with them, and we would always be in a state of unconsciousness: just as a person becomes unconscious when there begins to be too much life in his head, when instead of the regularly developed organs he has all sorts of growths. He is then unconscious intermittently, and later it becomes so severe that he lies there as if he were dead. Likewise in our original condition on the earth, as it was then, we could not have lived consciously. The human being could only awake to consciousness as the earth gradually died. And so mankind evolves on an earth that is dead.
So it is, gentlemen! And this is true not only of nature but also of civilization. If you think back to what I said just now—that below the earth there could be pagan temples and above Christian churches—you will see that the Christian churches are related to the pagan temples just as the upper strata to the lower, only that in one case we have to do with nature, in the other with culture. But one will not understand how the Christian element evolved if one does not observe that it evolved out of paganism as its foundation. In culture too we have to consider these strata.
Now I have said that the human being has actually been there all the time, but as a spiritual being, not a physical being. And that again leads us to look for the real reason why man did not evolve as a physical being earlier. We have said that in the air today there are nitrogen and oxygen, with carbon, hydrogen and sulphur to a lesser degree. In our breathing we ourselves unite the carbon that is in us with the oxygen we inhale and exhale the two together as carbon dioxide. In our human existence we breathe in oxygen and breathe out carbon dioxide; our life consists of that. We would long, long ago have filled the earth and the air of the earth with carbon dioxide had there not been something else on the earth: the plants. They have the same hunger for carbon that we have for oxygen. They take up the carbon dioxide eagerly, hold on to the carbon and give out the oxygen again.
You see, gentlemen, how wonderfully these things complement each other! We human beings need the oxygen out of the air, we inhale it, unite it with the carbon we have within us and exhale carbon and oxygen together as carbon dioxide. The plants breathe this in and breathe the oxygen out again, and so there is always oxygen in the air.
Well, this is true today but in human evolution on the earth it was not always like that. When we find the fossilized creatures that lived long ago, we realize that they could not have been like our modern animals and plants, particularly not like our present plants. All the primeval plants must have been much more like our sponges, mushrooms, algae. There is a difference between our mushrooms and our other present plants. The latter take in the carbon and form their body from it. When they sink into the ground, their body remains as coal. The coal we mine today is the remains of plants.
All the research we are able to pursue into the kinds of plants that originally existed tells us the following: Our present plants, including the plants which are now providing us with coal, are built up from carbon. But much earlier plants were formed not from carbon but from nitrogen. That was possible because just as carbon dioxide is exhaled today by animal and man, in ancient times a combination of carbon and nitrogen was exhaled. That is prussic acid, the terribly poisonous hydrocyanic acid fatal to all life today. This poisonous prussic acid was once exhaled, and nothing that exists today could then have arisen. The early mushroom-like plants took in the nitrogen and formed their body from it. The creatures about which I spoke last time, the bird-like beings and the heavy, coarse animal-beings, breathed out this poisonous acid, and the plants around them took the nitrogen to form their plant-body. Here, too, we can see that substances still existing today were used in quite a different way in ancient times.
I spoke of this once before to those of you who have been here for some time. I related how in 1906 I had to give some lectures in Paris4Paris, May 25-June 16, 1906: L'Esotérisme chrétien / Esquisse d'une cosmogonie psychologique, Paris 1957. on the evolution of the earth, the origin of man, and so forth. The subject led me to say: Can anything in this world show that carbon and oxygen have not always had the role they play today, that nitrogen once had that role, and that once the atmosphere consisted of prussic acid, of hydrocyanic acid?
Now you know that there are old people and young children. Well, if a man of seventy stands here and a child of two next to him, they are both human beings; they stand beside each other, and the one who is now seventy was like the two-year-old sixty-eight years ago. Things of different ages stand side by side. And it is the same in the universe; there, too, the older and the younger are side by side. Our earth, from what I have just now described and what you can still see today, our earth is a greybeard, an ancient fellow, almost dead already-if one does not count the life newly sprung up, one can call it almost dead. But at its side in the universe there are again younger forms which will only later become what our present life is. For instance, we must regard the comets as one of these. We can know, therefore, that since the comets are younger, they must still have conditions that belong to a younger age. The comets are to the earth what the child is to the old man. And if the earth once had prussic acid, the comets must now have it, they must have hydrocyanic acid! If with today's body one were to touch a comet, one would instantly die. It is diluted prussic acid that is in them.
I said in Paris in 1906 that this follows from the premises of spiritual science. Those who acknowledge spiritual science accepted my statement even though it astonished them. Then later, a fairly long time afterward, a comet made its appearance. By that time people had got the necessary instruments and it was then found by ordinary scientific methods that comets do have cyanide, prussic acid, as I had said in Paris in 1906. So it was confirmed.
Naturally, when people hear of this, they call it a coincidence: Oh sure, Steiner made that statement in Paris, and then there was the discovery—just a coincidence. They say this because they know nothing else. But I have now told you why one must take it for granted that there is prussic acid in the comets. It was no accident, it was genuine science by which one first reached this knowledge. Physical research only confirmed it later. People realize now that this is true for all that anthroposophy sets forth; for everything is confirmed later. Quite a number of things will be discovered today outside the Anthroposophical Movement that were already given out many years ago by anthroposophy in a rather different way.
Yes, there are many other things that could be carefully investigated today by science. I am always saying that if people could really travel to a star, they would be amazed to find it different from the modern ideas about it determined by their life on earth. They imagine that it contains a glowing gas. But that is not at all what is found out there. Actually, where the star is, there is empty space, empty space that would immediately suck one up. Suction forces are there. They would suck you up instantly, split you to pieces. If people would work with the same consistent research and the same unprejudiced thinking as we do here, they would also come to see with intricate spectroscopes that there are not gases out there, but negative suctional space.
Some time ago I gave certain individuals the task of investigating the sun and stars with the spectroscope, simply in order to prove by external methods that the stars are hollow spaces, not glowing gases. That can be proved. The persons to whom I gave this task were tremendously enthusiastic when they started: “Oh! then we shall get somewhere!” But sometimes enthusiasm fades away; they delayed too long. And then a year-and-a-half ago news came from America that people were starting to investigate the stars and were gradually finding out that they were not glowing gases but hollowed-out space! It is no disaster, of course, for such a thing to happen. But naturally, it would have been more useful to us – externally—if we had done it. But it doesn't matter, as long as truth comes to light.
On the other hand, however, it can be seen through just such things that anthroposophy really wants to work in collaboration with ordinary science. So it would also like to work with ordinary science on the strata of the earth. One thoroughly accepts what science has to say about the upheavals and overturnings in the Alps. But one cannot go along with the scientists when they assume that these upheavals were caused by forces that are still existing today. The fact is that there were life-forces there then; only life-forces could have flung and tossed these strata of living substance through one another. Anthroposophy already incorporates ordinary science and extends far beyond it, but science always wants to stop whenever it is too lazy to approach things more closely.
So—we will continue on Wednesday at nine o'clock.
Dritter Vortrag
Nun, meine Herren, Sie haben gesehen aus demjenigen, was wir besprochen haben, daß eigentlich in unserer Erde ein Zustand vorliegt, der nur der letzte Rest von vielem anderem ist, das wesentlich anders ausgeschaut hat. Und wenn wir heute den früheren Zustand der Erde mit etwas vergleichen wollen, so können wir ihn eigentlich nur, wie Sie gesehen haben, vergleichen mit demjenigen, was wir in einem Eikeim haben. Wir haben heute in der Erde einen festen Kern aus allerlei Mineralien und Metallen; wir haben ringsherum die Luft und haben in der Luft zwei Stoffe, die uns vor allen Dingen auffallen, weil wir ohne sie nicht leben können: den Sauerstoff und den Stickstoff. So daß wir also sagen können: Wir haben in unserer Erde einen festen Erdenkern mit allen möglichen Stoffen, siebzig bis achtzig Stoffen, und ringsherum die Lufthülle, vorzugsweise drinnen Stickstoff und Sauerstoff (es wird gezeichnet).
Aber das ist ja nur, daß vorzugsweise drinnen sind Stickstoff und Sauerstoff! Immer sind in der Luft auch andere Stoffe enthalten, nur eben in sehr geringer Menge, unter anderem Kohlenstoff, Wasserstoff, Schwefel. Aber das sind ja auch die Stoffe, die zum Beispiel in dem Weißen im Ei, im Weißen eines Hühnereies enthalten sind: Sauerstoff, Stickstoff, Wasserstoff, Kohlenstoff und Schwefel! Die sind auch im Weißen eines Hühnereies enthalten. Der Unterschied ist bloß der, daß in dem Weißen eines Hühnereies, ich möchte sagen, der Schwefel, der Wasserstoff, der Kohlenstoff mehr sich anschmiegen an den Sauerstoff und Stickstoff, während sie in der äußeren Luft viel loser vorhanden sind. Also eigentlich ist doch dasselbe in der Luft vorhanden, was in dem Hühnerei drinnen enthalten ist. In ganz geringer Menge sind auch dieselben Stoffe im Eidotter drinnen vorhanden. So daß wir also sagen können, daß es, wenn es sich verhärtet, verdichtet, zu dem wird, was die Erde ist. Sie sehen also, man muß auf solche Dinge hinschauen, wenn man wissen will, wie es in der Welt einmal ausgesehenhat. Heute aber macht man die Sache auf eine ganz andere Art, und damit Sie in der Beurteilung desjenigen, was ich Ihnen hier vorbringe, nicht beirrt werden durch dasjenige, was eben allgemein anerkannt ist, möchte ich Ihnen doch einiges von dem sagen, was allgemein anerkannt ist, und was dennoch durchaus übereinstimmt mit demjenigen, was ich sage. Man muß es nur richtig betrachten. Sehen Sie, heute denkt man ja nicht so, wie hier gedacht worden ist in den zwei letzten Stunden, sondern heute denkt man so, daß man sagt: Da haben wir die Erde. Die Erde ist einmal mineralisch. Diese mineralische Erde, die ist bequem zu untersuchen. Zunächst einmal untersuchen wir dasjenige, was obenauf ist, was wir mit unseren Füßen betreten. Dann sehen wir da, wenn wir Steinbrüche machen, wenn wir die Erde aufschließen, um Einschnitte zu machen beim Eisenbahnbau, wie gewisse Schichten vorhanden sind in der Erde. Da ist die oberste Schicht, auf die wir treten. Kommen wir irgendwo in die Tiefe hinein, dann finden wir tieferliegende Schichten. Aber diese Schichten liegen nicht so übereinander, daß man sagen kann, sie haben sich so hübsch übereinander aufgetürmt, immer ist die eine über der anderen -, sondern die Sache ist ja so: Sehen Sie einmal, nehmen Sie an, da haben Sie eine solche Schichte (siehe Zeichnung, rot); die ist nicht eben, diese Schichte, die ist gebogen; eine andere Schichte ist darunter (grün), die ist auch gebogen. Und jetzt kommt darüber diejenige Schichte, welche wir mit den Füßen betreten (weiß). Solange wir, sagen wir, auf dieser Seite eines Berges Fußgänger bleiben, so lang sehen wir da oben diejenige Schicht, die auch, wenn es gut geht, Ackererde werden kann, wenn wir die entsprechende Düngungsmethode und so weiter finden. Wenn wir aber eine Eisenbahn bauen, dann kann es sein, daß wir so heraufgehen müssen, daß wir also gewisse Schichten abbauen müssen. Und dann kommen wir dadurch, daß wir einen solchen Einschnitt machen, in die Tiefen der Erde hinein. Und auf eine solche Weise hat man gefunden, daß eben übereinander Schichten sind, nicht ebene, sondern in der verschiedensten Weise durcheinandergeworfene Schichten der Erde.
Aber diese Schichten sind manchmal sehr merkwürdig. Man hat sich gefragt: Wie kann man das Alter der Schichten bestimmen? Welche Schichte ist älter? - Nun ja, das Nächstliegende ist ja das, daß einer sagt: Wenn die Schichten übereinander sind, so ist die unterste die älteste, die darauf folgende ist jünger, und die oben liegende ist die allerjüngste. Aber sehen Sie, so ist die Geschichte nicht überall; manchmal ist es so, aber nicht überall ist es so. Und daß es nicht überall so ist, das kann man auf folgende Weise konstatieren.
Wir sind ja in unseren kultivierten Gegenden gewöhnt, unsere Haustiere, wenn sie sterben, zu verscharren, damit sie für die Menschen nicht schädlich werden. Wäre aber das Menschengeschlecht noch nicht entwickelt, was würde dann mit den Tieren, die da schon da wären, geschehen? Die Tiere würden an irgendeiner Stelle verenden, würden da liegenbleiben. Nun liegt das Tier zunächst da oben. Aber Sie wissen ja, wenn es regnet, wird die Erde aufgespült, und nach einiger Zeit könnte man sehen, wenn da ein Tier verendet wäre, daß dieses Tier, indem es anfängt zu verwesen, in seinen Überresten, die übrig bleiben, sich vermischt mit der vom Regen herangeschlagenen Erde. Und nach einer Zeit ist das ganze Tier durchzogen mit der vom Regen herangeschwemmten Erde oder von dem Regenwasser, das herunterfließt über einen Abhang; dann geht über das Tier die andere Erde darüber. Nun kann einer kommen hinterher und kann sagen: Donnerwetter, die Erde schaut ja da so geringelt aus, da muß ich mal nachgraben! - Da braucht er nicht viel nachzugraben; er gräbt etwas nach und findet darinnen — sagen wir, wenn die Menschen noch nicht dagewesen wären und eben hinterher der gekommen wäre, der nachgegraben hätte -, da findet er dasjenige, was übrig ist vom Knochengerüste, sagen wir, von einem wilden Pferd. Da kann er sich sagen: Ja, jetzt gehe ich über eine Erdschichte, die erst später geworden ist; aber die drunter ist eine, die ist gebildet worden zu einer Zeit, wo schon solche wilden Pferde da waren. — Und man kann erkennen, daß das die nächste Schichte ist, daß also der Zeit, in der dieser Mensch lebt, eine vorangegangen ist, worin diese Pferde gelebt haben.
Sehen Sie, so wie es der Mensch hier macht, haben es nun die Geologen mit allen Schichten der Erde gemacht; sie haben sie einfach, seit sie zu erreichen sind in Steinbrüchen, in Eisenbahnaufschließungen und so weiter, abgegraben. Man lernt ja in der Geologie, daß man mit einem Hammer oder auch mit einem anderen Instrument überall Steinbrüche aufsucht, um eben aufzuschließen dasjenige, was im Gebirge durch Abrutschungen bloßgelegt ist oder dergleichen. Da hämmert man überall ein, sägt unter Umständen auch das eine oder andere aus, und da findet man in irgendeiner Schichte sogenannte Versteinerungen. Da kann man sagen: Unter unserem Erdboden sind die Schichten erhalten, die ganz andere Tiere als die heutigen enthalten haben. - Und man kommt dann darauf, wie die Gestalt der Tiere ist, die in alten Zeiten vorhanden waren, wenn man in dieser Weise die Schichten der Erde abgräbt.
Das ist gar nicht so etwas Besonderes, denn, sehen Sie, in welcher Zeit so etwas geschieht, das unterschätzen die Leute eigentlich. Sie finden heute in südlicheren Gegenden Kirchen oder andere Gebäude; die stehen da. Sie kommen durch irgend etwas darauf — Donnerwetter, da unter dieser Kirche, das ist ja etwas, was hart ist, was nicht Erde ist. Sie graben hinein und finden, daß da drunter ein heidnischer Tempel ist! Ja, was ist denn da geschehen? Vor verhältnismäßig kurzer Zeit, da war diese Oberschicht überhaupt nicht da, auf der diese Kirche oder dieses Gebäude steht, sondern das ist erst angetragen, angeschleppt worden vielleicht von Menschen, aber vielleicht auch durch Mithelfen der Naturkräfte, und drunten ist der heidnische Tempel. Das war oben, was jetzt drunten ist. So ist es. Aber in der Erde, da ist Schichte auf Schichte aufgeschichtet worden. Und man muß herausfinden, nicht aus der Art, wie die Schichten liegen, sondern aus der Art und Weise, wie diese Versteinerungen, wie diese versteinerten Tiere liegen — und dazu kommen auch die verschiedenen Pflanzen —, wie diese in die Schichten hereingekommen sind.
Da stellt sich aber folgendes heraus. Sehen Sie, da kann folgendes passieren: Sie finden eine Erdschichte (siehe Zeichnung, gelb); Sie finden eine andere Erdschichte (grün); Sie sind in der Lage durch irgend etwas, hier hineinzugraben (Pfeil). Wenn Sie jetzt bloß auf die Schichtungen schauen, dann kommt es Ihnen doch vor, wie wenn das, was ich da grün gezeichnet habe, die untere Schichte wäre, und dasjenige, was ich gelb gezeichnet habe, die obere Schichte. Hierher können Sie einfach nicht; da können Sie nicht eingraben, da ist keine Eisenbahn, kein Tunnel, noch irgend etwas anderes, wodurch man hinkommen kann. Da merken Sie: Das Gelbe ist die Oberschichte, das Grüne ist die untere Schichte. Aber Sie dürfen das nicht gleich sagen, sondern Sie müssen erst die Versteinerungen suchen. Nun findet man sehr häufig in dem, was da oben liegt, Versteinerungen, die älter sein müssen. Man findet zum Beispiel da oben merkwürdige Fischskelette, und unten findet man, sagen wir, merkwürdige Säugetierskelette, die jünger sind. Jetzt widersprechen die Versteinerungen der Lage: Oben erscheint das Ältere, unten erscheint das Jüngere. Jetzt muß man sich eine Vorstellung machen, woher das kommt. Ja, sehen Sie, das kommt davon her, daß durch irgendein Erdbeben oder eine innere Erschütterung dasjenige, was hier unten war, sich herumgeschmissen hat über das Obere, so daß also dieses entstanden ist, daß, wenn ich hier Ihnen den Stuhl über den Tisch legen würde, wenn das die ursprüngliche Lage wäre der Stuhliehne und hier der Tischplatte -, so würde es geschehen, daß durch einen Erdstoß, der hier erfolgt ist, die Tischplatte sich über die Stuhllehne drüberstülpt.
Sehen Sie, das kann man an dem Verschiedensten wahrnehmen: es hat sich das umgestülpt. Und man kann, wie Sie gleich daraus sehen, auch folgendes noch wissen. Man kann fragen: Wann ist diese Umstülpung geschehen? Diese Umstülpung ist ja erst geschehen, nachdem diese Versteinerungen sich gebildet haben; sonst müßten diese anders drinnen liegen. Also man weiß, daß diese Umstülpung, diese Umschichtung später entstanden ist als diese Tiere gelebt haben.
Auf diese Weise kommt man darauf, die Erdschichten nicht so zu beurteilen, wie sie einfach übereinanderliegen, sondern so zu beurteilen, wie sie sich auch umgeschichtet haben. Und sehen Sie, die Alpen, dieser mächtige Gebirgszug, der sich vom Mittelländischen Meere hinüberzieht bis in die österreichischen Donaugegenden — diesen mächtigen Alpenzug, der das Hauptgebirge der Schweiz ist, den kann man überhaupt nicht verstehen, wenn man nicht auf solche Dinge eingehen kann. Denn in diesen Alpen ist alles, was schichtweise sich aufgebaut hat, später einmal durcheinandergeschmissen worden. Da liegt oft das Unterste zuoberst und das Oberste zuunterst und man muß erst suchen, wie da die Dinge durcheinandergeschmissen worden sind.
Nun, erst wenn man das berücksichtigt, kommt man darauf, welches die ältesten Schichten sind und welches die jüngsten Schichten sind. Und da sagt natürlich diese heutige, nur aufs Äußerliche dieser Forschung bauende Wissenschaft: Diejenigen Schichten sind die ältesten, in denen die allereinfachsten Überreste von Tieren und Pflanzen gefunden werden können. Später werden die Tiere und Pflanzen kompliziert - also finden sich die komplizierteren der Tiere und Pflanzen in den jüngeren Schichten. Wenn man an ältere Schichten herankommt, so findet man Versteinerungen, die davon herrühren, daß sich dasjenige, was die Tiere an Kalk- oder Kieseleinschlüssen gehabt haben, erhalten hat; das andere hat sich ja aufgelöst. Wenn man an jüngere Schichten kommt, hat sich das Skelett erhalten. - Nur bilden sich nämlich, merkwürdigerweise, auch auf andere Art Versteinerungen. Diese anderen Versteinerungen sind unter Umständen sehr interessant.
Sehen Sie, sie bilden sich auch so, diese Versteinerungen: Denken Sie sich, irgendein einfaches älteres Tier sei einmal vorhanden gewesen, ein Tier, das einen Leib hat, meinetwillen vorne Fangarme (weiß) — ich zeichne es so groß, es wird in den Schichten, die aus dem Geologischen bekannt sind, in der Regel kleiner sein. Nun, dieses Tier verendet, indem es auf diesem Erdreiche liegt. Nehmen wir an, das Erdreich ist so, daß es nicht recht hinein kann in das Tier; dieses Erdreich, das meidet sozusagen irgendeine Säure, die in dem Tier enthalten ist. Dann entsteht etwas sehr Merkwürdiges; dann geht die Erde, in der dieses Tier dadrinnen liegt, überall an das Tier heran und umhüllt das Tier (gelb), und es bildet sich ein Hohlraum von der Form des Tieres.
Das ist sehr häufig entstanden, daß sich solche Hohlräume bilden (grün). Um das Tier herum lagert sich die Erde. Aber es ist nichts drinnen, es durchsaugt nicht das Tier, sondern ringsherum, weil das Tier schalig war, bildet sich solch ein Hohlraum. Nun, später wird aber die Schale aufgelöst; und noch später windet sich irgendein Bach da durch; der füllt dann mit seiner Gesteinsmasse das, was ein Hohlraum ist, aus (grün), und da drinnen wird fein modelliert ein Abdruck des Tieres mit einer ganz anderen Materie, mit einem ganz anderen Stoffe. Solche Abdrücke sind ganz besonders interessant, denn da haben wir nicht die Tiere selber, sondern Abgüsse der Tiere.
Nun, sehen Sie, Sie dürfen sich aber auch die Dinge nicht so ganz leicht vorstellen. Von dem heutigen Menschen zum Beispiel mit seiner verhältnismäßig weichen Stofforganisation bleibt außerordentlich wenig vorhanden, und von höheren Tieren ist auch verhältnismäßig wenig vorhanden gewesen. So zum Beispiel gibt es Tiere, von denen nur Abgüsse der Zähne vorhanden geblieben sind; eine Art Abgüsse urweltlicher Haifischzähne, die sich auf diese Weise gebildet haben, findet man. Jetzt muß man schon die Fähigkeit haben, sich zu sagen: Jede Tierform hat ihre eigene Zahnform — der Mensch hat eine andere Zahnform -, und die Zahnform richtet sich immer nach der ganzen Gestalt, dem ganzen Wesen. Jetzt muß man das Talent haben, aus den Zähnen, die man da findet, sich vorstellen zu können, wie das ganze Tier gewesen sein kann. Also so ganz leicht ist die Sache doch nicht.
Aber sehen Sie, man kommt, indem man diese Schichten da studiert, auch darauf, wie eigentlich sich die ganze Sache entwickelte. Und daraus geht einfach hervor, daß es Zeiten gegeben hat, in denen solche Tiere, wie sie heute da sind, nicht da waren, sondern in denen Tiere dagewesen sind, die viel, viel einfacher waren, die so ausgeschaut haben wie unsere ganz niederen Tiere, das Schnecken-, das Muschelgetier und so weiter. Aber Sie müssen überall wissen, was von diesen Tieren übriggeblieben ist. Denken Sie nur einmal, es könnte ja folgendes eintreten.
Nehmen Sie einmal an, ein kleiner Junge, der Krebse nicht mag, stibitze sich einen Krebs von der Mahlzeit seiner Eltern und spiele mit ihm. Er wird nicht erwischt und gräbt ihn ein in den Garten. Nun hat der im Garten den Krebs eingegraben. Über die ganze Sache kommt Erde drüber; es wird vergessen. Den Garten hat ein anderer später; der gräbt um, wird aufmerksam an einer Stelle: Da findet er komischerweise zwei kleine Dinger, die so wie kleine Kalkschalen ausschauen. Sie wissen, daß es die sogenannten Krebsaugen gibt, die ja nicht Augen sind, sondern kleine Kalkschalen, die im Leibe des Krebses sind. Das sind die einzigen Zeichen, die von seinen Spuren geblieben sind. Jetzt können Sie nicht sagen: Das sind Versteinerungen von irgendeinem Tier -, sondern das sind Versteinerungen nur von einem Teil des Tieres. So kann man in älteren Schichten irgendwelche Gebilde finden, meinetwillen so aussehend, wie eine Schale aussehend, namentlich in den Alpen. Die sehen so ähnlich aus; die gibt es heute nicht mehr, die findet man in älteren Schichten. Man darf nicht annehmen, daß dies die ganzen Tiere gewesen sind, sondern man muß eben annehmen: Da war eben etwas herum, das hat sich aufgelöst, und nur ein kleines Stück von dem Tier ist geblieben.
Darauf geht schon die heutige Wissenschaft wenig ein. Warum? Ja, weil sie eben nur so sagt: Dieses mächtige Alpenmassiv, das zeigt ja, daß es durcheinandergeschmissen worden ist, das Unterste zuoberst, das Oberste zuunterst; das zeigen die Schichten. — Aber, meine Herren, können Sie sich vorstellen, daß mit den Kräften, die heute auf der Erde vorhanden sind, solch ein Alpenmassiv in der Weise durcheinandergeschmissen werden kann? Das bißchen, was heute geschieht auf der Erde, geschieht ja so, daß vergleichsweise die Erde durchtanzt wird, daß die Erde von einem Fleck ein bißchen auf einen anderen geworfen wird; das ist heute alles, dieses Durchtanztwerden. Würde der Mensch statt zweiundsiebzig Jahre siebenhundertzwanzig Jahre alt, dann würde er erleben, wie er in seinem Greisenalter schon über einen ein wenig höheren Boden geht als vorher. Aber wir leben ja zu kurz. Denken Sie nur, wenn uns eine Eintagsfliege, die nur vom Morgen bis zum Abend lebt, erzählen würde, was sie erlebt, die würde uns erzählen, da sie nur im Sommer lebt: Es gibt überhaupt nur Blüten, die ganze Zeit nur Blüten. — Die würde ja gar keine Ahnung davon haben, was im Winter geschieht und so weiter; sie würde glauben, der nächste Sommer schließe sich an den vorigen an. Wir Menschen sind zwar ein bißchen länger dauernde Eintagsfliegen, aber etwas von Eintagsfliegen haben wir doch schon an uns mit unseren siebzig bis zweiundsiebzig Jahren! Nun, die Sache ist schon so, daß wir wenig sehen von dem, was vorgeht. Und so muß man sagen: Mit den Kräften, die heute wirksam sind, geschieht zwar mehr, als der Mensch gewöhnlich sieht, aber es geschieht doch verhältnismäßig nur das, daß der Boden ein bißchen aufgeschwemmt wird, daß Flüsse gegen das Meer hinfließen, Flußsand zurücklassen, daß dann an den Ufern der Flußsand weitergeht, daß die Felder eine neue Schichte bekommen. Das ist verhältnismäßig wenig. Hält man sich vor Augen, wie so etwas wie dieses Alpenmassiv durchgerüttelt und durchgeschüttelt worden ist, dann muß man sich klar sein, daß die Kräfte, die heute wirksam sind, früher in einer ganz anderen Weise wirksam waren.
Nun aber müssen wir uns Bilder machen, wie so etwas vor sich gehen kann. Ja, nehmen Sie nur einmal irgendeinen Eikeim, einen Eikeim von irgendeinem Säugetier. Der schaut anfangs verhältnismäßig sehr einfach aus: ringsherum Eiweißmasse, drinnen ein Kern (es wird gezeichnet). Aber nehmen Sie an, dieser Eikeim wird befruchtet. Sehen Sie, wenn er befruchtet wird, da macht der Kern dann allerlei Sperenzchen; er bildet sich, sehr merkwürdig, zu einer Summe von solchen Spiralen aus, die wie ein Schwanz heraufgehen. So bildet sich der Kern aus. In dem Moment, wo diese Knäuelchen entstehen, entstehen aus der Masse heraus sternförmige Gebilde; da kommt die ganze Masse dadurch, daß Leben in ihr ist, in Gestaltungen hinein. Da geht es schon anders zu als heute auf unserer Erde! Dadrinnen entstehen schon solche Umstülpungen und Überwerfungen, wie wir sie im Alpenmassiv sehen!
Was ist natürlicher, als daß wir sagen: Also war die Erde einmal lebendig, sonst hätten diese Umstülpungen und Überwerfungen gar nicht entstehen können! Die heutige Gestalt der Erde zeigt uns eben, daß sie in der Zeit, in der noch nicht Menschen, in der noch nicht höhere Tiere gelebt haben, selber lebendig war! So daß wir auch aus dieser Erscheinung heraus sagen müssen: Aus der lebendigen Erde ist die heutige tote Erde erst hervorgegangen. — Aber nur in dieser heutigen toten Erde können die Tiere leben! Denn denken Sie einmal, es hätte in der Luft sich nicht abgesondert für sich der Sauerstoff und Stickstoff und hätte sozusagen den Wasserstoff, den Kohlenstoff, den Schwefel zu einer verhältnismäßigen Tatenlosigkeit verdammt, so müßten wir atmen in so etwas, was ähnlich wäre dem Eiweiß im Hühnerei, denn so war es ringsherum um die Erde.
Nun könnte man sich zum Beispiel denken — denn in der Welt kann ja alles entstehen -, daß sich statt unserer Lunge auch Organe gebildet hätten, durch die man einsaugen könnte solch ein atmosphärisches Eiweiß. Wir können es ja heute durch den Mund verzehren. Warum sollte nicht etwas mehr gegen den Mund hinüber eine Art Lungenorgane entstanden sein? Auf der Welt kann alles entstehen. Es entsteht auch das, was da noch möglich ist. Also am Menschen liegt es eigentlich, zunächst so, wie er heute ist, eigentlich körperlich nicht. Aber bedenken Sie doch nur, meine Herren: Wir gucken, wenn wir heute in die Luft gucken, in die tote Luft hinein. Die ist abgestorben. Früher war das Eiweiß lebendig. Die Luft ist abgestorben; gerade dadurch, daß der Schwefel, der Wasserstoff, der Kohlenstoff weg ist, ist der Stickstoff und Sauerstoff abgestorben. Wir gucken hinein in die lichterfüllte Luft, die abgestorben ist. Dadurch können unsere Augen auch physikalisch sein, sind auch physikalisch. Wäre in unserer Umgebung alles lebendig, so müßten auch unsere Augen lebendig sein. Wenn sie lebendig wären, könnten wir nichts mit ihnen sehen, und wir wären fortwährend in einer Ohnmacht, geradeso wie wir in Ohnmacht kommen, wenn es in unserem Kopf zu stark zu leben anfängt, wenn wir in unserem Kopf, statt daß wir die regelmäßig ausgebildeten Organe haben, allerlei Gewächse haben, werden wir auch ohnmächtig, zuerst ab und zu und später wird die Anzahl so stark, daß Sie wie tot daliegen. Also so, wie wir ursprünglich waren, hätten wir doch nicht mit Bewußtsein leben können in dieser Erde. Das Menschenwesen konnte erst zum Bewußtsein erwachen, als die Erde allmählich abgestorben war. So daß wir uns als Menschenwesen entwickeln eben auf der abgestorbenen Erde.
So ist es ja auch, meine Herren! So ist es ja nicht nur mit der Natur, sondern auch mit der Kultur. Wenn Sie noch einmal auf das hinschauen, was ich gesagt habe, daß da unten heidnische Tempel sein konnten, oben christliche Kirchen, so verhalten sich diese christlichen Kirchen zu den heidnischen Tempeln geradeso wie die oberen zu den unteren Schichten; nur in dem einen Fall haben wir es mit der Natur, im anderen Fall mit der Kultur zu tun. Aber man kann auch nicht verstehen, wie das Christliche sich entwickelt, wenn man es nicht betrachtet, wie es sich auf der Grundlage des Heidentums entwickelte. So ist es schon mit der Kultur. Auch da muß man diese Schichten beobachten.
Nun sagte ich Ihnen aber: Der Mensch war eigentlich immer da, nur nicht als solches physisches Wesen, sondern als mehr geistiges Wesen. — Und das wiederum führt uns dazu, den eigentlichen Grund einzusehen, warum der Mensch nicht schon früher sich als physisches Wesen entwickelte. Sehen Sie, ich habe Ihnen gesagt: Da sind in der Luft heute Stickstoff, Sauerstoff — Kohlenstoff, Wasserstoff und Schwefel weniger. Heute bringen wir selber den Kohlenstoff, den wir in uns haben, bei der Atmung mit dem Sauerstoff, den wir einatmen, zusammen, verbinden den Kohlenstoff mit dem Sauerstoff, stoßen den miteinander verbundenen Kohlenstoff und Sauerstoff, was man Kohlensäure nennt, wieder aus. Wir Menschen leben also so, daß wir Sauerstoff einsaugen durch die Atmung und Kohlensäure ausstoßen. Darin besteht unser Leben. Längst hätten wir als Menschen die Erde, die Erdenluft ganz angefüllt mit Kohlensäure, wenn nicht etwas anderes wäre. Das sind die Pflanzen; die haben einen ebensolchen Hunger, wie wir nach dem Sauerstoff haben, nach dem Kohlenstoff. Die Pflanzen wiederum nehmen gierig die Kohlensäure auf, behalten den Kohlenstoff zurück und geben Sauerstoff wieder her.
Sie sehen, meine Herren, wie wunderbar sich eigentlich das ergänzt! Es ergänzt sich ganz famos. Wir Menschen brauchen aus der Luft den Sauerstoff, den atmen wir ein; wir geben ihm den Kohlenstoff mit, den wir in uns haben, atmen Kohlenstoff und Sauerstoff zusammen aus als Kohlensäure. Die Pflanzen atmen sie ein und atmen den Sauerstoff wieder aus. Und so ist immer wiederum in der Luft Sauerstoff da.
Ja, das ist heute so; aber in der Entwickelung der Menschheit auf Erden war es nicht immer so. Gerade wenn wir die alten Wesen finden, die da gelebt haben, die wir sogar noch in den Versteinerungsschichten drinnen finden können, dann sagen wir uns: Ja, die können nicht so gewesen sein, wie unsere heutigen Tiere und Pflanzen sind, namentlich nicht so, wie die Pflanzen heute sind, sondern alle diese Wesen, die ursprünglich da waren als Pflanzen, die müssen viel ähnlicher gewesen sein unseren Schwämmen, den Pilzen und den Algen. Nun besteht aber ein Unterschied zwischen unseren Pilzen und unseren heutigen Pflanzen. Der Unterschied liegt darinnen: Unsere heutigen Pflanzen nehmen den Kohlenstoff auf, bilden sich daraus ihren Leib. Wenn dann solche Pflanzen versinken in der Erde, dann bleibt der Leib als Kohle darinnen. Was wir heute als Kohle ausgraben, sind Pflanzenleiber.
Meine Herren, alles das, was wir untersuchen können in bezug darauf, was für Pflanzen ursprünglich gelebt haben, zeigt uns: Die heutigen Pflanzen, auch diejenigen Pflanzen, die uns einmal unsere Kohlen geliefert haben, die wir heute aus der Erde ausgraben, die bauen sich aus Kohlenstoff auf. Aber viel frühere Pflanzen haben sich nicht aus Kohlenstoff aufgebaut, sondern aus Stickstoff. Geradeso wie sich unsere heutigen Pflanzen aus Kohlenstoff aufbauen, so haben sich diese Pflanzen aus Stickstoff aufgebaut. Wodurch ist denn das möglich geworden? Sehen Sie, das ist dadurch möglich geworden, daß geradeso, wie heute die Kohlensäure ausgeatmet wird von den Tieren und Menschen, in alten Zeiten ausgeatmet wurde eine Verbindung von Kohlenstoff und Stickstoff. Heute atmen wir eine Verbindung von Kohlenstoff und Sauerstoff aus, früher wurde ausgeatmet eine Verbindung von Kohlenstoff und Stickstoff. Aber, meine Herren, das ist die Blausäure, die für alles, was heute lebt, so furchtbar giftige Blausäure, die Zyansäure! Diese giftige Blausäure, die wurde einmal ausgeatmet, und die verhinderte, daß so etwas, wie es heute lebt, entstehen konnte. Diese Blausäure ist eben eine Verbindung von Stickstoff und Kohlenstoff. Da wird der Kohlenstoff noch nicht angenommen von diesen pilzartigen Pflanzen, sondern da wird der Stickstoff angenommen. Diese alten Pflanzen, die bauten sich aus dem Stickstoff auf. Und die Wesenheiten, von denen ich Ihnen gesprochen habe, diese vogelartigen Gebilde, und diese plumpen Tiere, von denen ich Ihnen das letzte Mal gesprochen habe, die atmeten diese giftige Säure aus, und die Pflanzen, die um sie herum waren, nahmen den Stickstoff und bildeten sich daraus ihren Leib, ihren Pflanzenleib. So daß wir auch da sehen können, daß die Stoffe, die heute noch da sind, eben in ganz anderer Weise verwendet worden sind in alten Zeiten.
Und das ist es eben, wovon ich einmal aus der Anthroposophie heraus gesprochen habe; ich habe es den Herren, die länger da sind, schon erzählt: 1906 hatte ich Vorträge in Paris zu halten über Erdentwickelung, Menschenentstehung und so weiter, und da mußte ich sagen aus dem ganzen Zusammenhang heraus: Kann man heute noch irgendwo etwas finden, was uns darauf hinweist, daß einmal auch auf der Erde nicht der Kohlenstoff und der Sauerstoff die Rolle gespielt haben, die sie heute spielen, sondern daß da der Stickstoff eine solche Rolle gespielt hat, daß gewissermaßen eine Atmosphäre von Blausäure da war, von Zyansäure?
Nun wissen Sie ja das Folgende: Es gibt alte Leute und kleine Kinder. Da kann einer stehen mit siebzig Jahren und neben ihm ein Kind von zwei Jahren — das eine ist ein Mensch, und der andere ist ein Mensch. Sie stehen eben nebeneinander, und derjenige, der heute siebzig Jahre alt ist, war eben vor achtundsechzig Jahren wie das kleine Kind. Die Dinge, die verschiedenalterig sind, stehen doch im Leben nebeneinander. So wie es aber im Menschenleben ist, ist es eben auch in der Welt. Auch da stehen gewissermaßen ältere Dinge und jüngere nebeneinander. In unserer Erde mit dem, was ich Ihnen jetzt beschrieben habe, was Sie heute noch sehen, ist ein richtiges Greisenhaftes, sogar schon fast Erstorbenes — wenn man nicht das Leben, das wieder neu aufgesprossen ist, nimmt -, ein sogar fast Erstorbenes vorhanden. Aber daneben sind im Weltenall wieder jüngere Gebilde, die erst so werden, wie unser heutiges Leben ist. Und als solche muß man zum Beispiel die Kometen anschauen. Daher kann man wissen, daß die Kometen, weil sie eben jünger sind, auch noch diejenigen Zustände haben müssen, die ihrem Jüngersein entsprechen. So wie das Kind dem Greis gegenüber, so stehen die Kometen der Erde gegenüber: Hat die Erde einmal Blausäure gehabt, so müssen die Kometen jetzt noch Blausäure haben; Zyanverbindungen müßten sie haben! So daß man mit einem heutigen Körper, wenn man lecken würde an dem Kometen, sogleich sterben müßte. Das ist allerdings verdünnte Blausäure, die dadrinnen ist.
Nun, sehen Sie, das habe ich 1906 in Paris gesagt, daß dies aus der Geisteswissenschaft folgt. Nun ja, zunächst haben diejenigen, die Geisteswissenschaft anerkennen, das angenommen; man kann sich sogar über so etwas verwundern. Dann später, längere Zeit darauf, ist wieder ein Komet erschienen. Da hatte man schon die Instrumente, die nötig sind, und da fand man auch durch die gewöhnliche Naturforschung, daß die Kometen wirklich Zyan haben, Blausäure —- was ich damals in Paris gesagt hatte! So werden die Dinge eben bestätigt. Natürlich sagen dann die Leute, weil sie nur dieses hören: Der Steiner hat in Paris gesagt, die Kometen haben Blausäure, nachher ist es gefunden worden — das ist ein Zufall! — So sagen die Leute, weil sie nichts anderes als dieses wissen: Das ist ein Zufall. - Aber ich habe Ihnen jetzt gesagt, warum man in den Kometen Blausäure annehmen muß. Da sehen Sie, es ist kein Zufall, es ist eine wirkliche Wissenschaft, durch die man darauf gekommen ist! Nur eben, mit der sinnlichen Forschung wird das erst später bestätigt. Und so könnten die Leute schon ansehen das, was in der Anthroposophie ist: Alles wird später bestätigt. Sogar häufig wird es heute schon außerhalb der anthroposophischen Bewegung, eben auf eine etwas andere Art, gefunden werden, was aber von der Anthroposophie schon vor vielen Jahren gegeben worden ist.
Ja, es kommen sogar noch andere Sachen vor, meine Herren. Das ist etwas, was heute ganz wissenschaftlich untersucht werden könnte. Ich muß immer sagen: Wenn die Menschen zu einem Stern wirklich hinausfahren könnten, da würden sie sehr erstaunt sein, daß der anders ausschaut, als sie sich ihn aus den heutigen Erdenvorstellungen vorstellen. Da stellt man sich vor, da ist so ein glühendes Gas drinnen. Aber das findet man gar nicht draußen, sondern wo der Stern ist, da ist eigentlich leerer Raum, aber ein leerer Raum, der einen gleich aufsaugt. Saugekräfte sind da! Es saugt einen gleich auf und zersplittert: einen. Und wenn man nun mit derselben Forschung so konsequent vorgeht und eine solche unbefangene Denkweise hat, wie wir es hier haben, so kann man auch darauf kommen, mit komplizierten Spektroskopen zu sehen: Da sind nicht Gase, sondern da ist der saugende Raum. — Und ich habe schon vor längerer Zeit gewissen unserer Leute die Aufgabe gegeben, mit dem Spektroskop einmal die Sonne und die Sterne zu untersuchen, um einfach nachzuweisen mit äußeren Erfahrungen, daß die Sterne Hohlräume sind, nicht glühende Gase. Und das kann man nachweisen. Aber diejenigen Leute, denen ich diese Aufgabe gegeben habe, waren anfangs furchtbar begeistert: Oh, da wird etwas gemacht! — Aber manchmal erlischt diese Begeisterung; sie haben zu lange gewartet — und schon vor anderthalb Jahren kam von Amerika herüber die Nachricht, daß man auf dem Weg ist, die Sterne zu untersuchen, und nach und nach findet, daß die Sterne gar nicht glühende Gase sind, sondern ausgesparte Hohlräume! Es schadet ja auch nichts, wenn das so geschieht. Natürlich, äußerlich wäre es uns nützlicher, wenn wir es machten. Aber es kommt ja nicht darauf an; wenn nur die Wahrheit herauskommt.
Auf der anderen Seite aber könnte gerade durch solche Sachen gesehen werden, wie Anthroposophie eigentlich mit der gewöhnlichen Wissenschaft zusammenarbeiten will. Und so möchte sie auch durchaus zusammenarbeiten mit der gewöhnlichen Wissenschaft, zum Beispiel in bezug auf die Erdschichten. Man nimmt ja durchaus an, was die gewöhnliche Wissenschaft zu sagen hat über das Durcheinanderschmeißen und Durcheinanderwürfeln in den Alpen. Nur kann man nicht mitgehen, wenn man annimmt, das wird so herumgeschmissen mit den Kräften, die heute noch da sind; sondern da waren eben Lebenskräfte da, die nur dieses Lebendige durcheinanderschmeißen können! — Also, Anthroposophie steckt wahrlich in der gewöhnlichen Wissenschaft schon drinnen. Die gewöhnliche Wissenschaft will nur da überall aufhören, wo sie zu faul ist, an diese Dinge wirklich heranzukommen.
Dann am Mittwoch um neun Uhr Fortsetzung.
Third Lecture
Well, gentlemen, you have seen from what we have discussed that the state of our Earth is actually only the last remnant of many other states that looked very different. And if we want to compare the former state of the Earth with something today, we can really only compare it, as you have seen, with what we have in an egg. Today, we have a solid core of all kinds of minerals and metals in the Earth; we have the air around it, and in the air we have two substances that strike us above all else because we cannot live without them: oxygen and nitrogen. So we can say that we have a solid core in our Earth with all kinds of substances, seventy to eighty substances, and around it the air envelope, primarily containing nitrogen and oxygen (drawing is made).
But that only means that nitrogen and oxygen are predominantly present! The air always contains other substances as well, but only in very small quantities, including carbon, hydrogen, and sulfur. But these are also the substances that are contained in the white of an egg, for example: oxygen, nitrogen, hydrogen, carbon, and sulfur! They are also contained in the white of a chicken egg. The only difference is that in the white of a chicken egg, I would say, the sulfur, hydrogen, and carbon cling more closely to the oxygen and nitrogen, whereas in the outside air they are present in a much looser form. So, in fact, the same substances are present in the air as are contained in the chicken egg. The same substances are also present in very small quantities in the egg yolk. So we can say that when it hardens and condenses, it becomes what the earth is. So you see, you have to look at things like this if you want to know what the world once looked like. Today, however, things are done in a completely different way, and so that you are not misled in your assessment of what I am presenting to you here by what is generally accepted, I would like to tell you some of what is generally accepted and which nevertheless is entirely consistent with what I am saying. You just have to look at it correctly. You see, today people don't think the way we have been thinking here for the last two hours, but today people think that we have the earth. The earth is mineral. This mineral earth is easy to study. First of all, we examine what is on top, what we walk on with our feet. Then we see, when we quarry, when we open up the earth to make cuts for railroad construction, how certain layers are present in the earth. There is the top layer, which we walk on. If we go somewhere deep down, we find deeper layers. But these layers are not stacked on top of each other in such a way that one can say they are neatly piled up, with one always above the other – rather, the situation is as follows: suppose you have a layer like this (see drawing, red); this layer is not flat, it is curved; another layer is underneath it (green), which is also curved. And now comes the layer above it, which we walk on (white). As long as we remain pedestrians on this side of a mountain, so to speak, we see the layer above us, which, if all goes well, can become arable land if we find the right fertilization method and so on. But if we build a railroad, we may have to go up, which means we have to remove certain layers. And then, by making such an incision, we enter the depths of the earth. And in this way, it has been discovered that there are layers on top of each other, not flat, but layers of earth thrown together in the most diverse ways.
But these layers are sometimes very strange. People have asked themselves: How can we determine the age of the layers? Which layer is older? Well, the most obvious answer is that if the layers are on top of each other, the lowest is the oldest, the next one is younger, and the one on top is the youngest. But you see, that's not always the case; sometimes it is, but not everywhere. And the fact that this is not the case everywhere can be established in the following way.
In our civilized regions, we are accustomed to burying our pets when they die so that they do not become harmful to humans. But if the human race had not yet developed, what would happen to the animals that were already there? The animals would die somewhere and remain lying there. At first, the animal would lie there. But you know that when it rains, the earth is washed away, and after a while, if an animal had died there, you would see that as it began to decay, its remains would mix with the earth washed away by the rain. And after a while, the whole animal is permeated with the soil washed up by the rain or by the rainwater flowing down a slope; then the other soil covers the animal. Now someone can come along afterwards and say: Wow, the soil looks so curled up there, I'll have to dig it up! He doesn't need to dig very far; he digs a little and finds inside — let's say, if humans hadn't been there yet and the one who dug had come along afterwards — he finds what is left of the skeleton, let's say, of a wild horse. Then he can say to himself: Yes, now I am walking on a layer of earth that was formed later; but the one underneath was formed at a time when such wild horses already existed. — And one can recognize that this is the next layer, that the time in which this man lives was preceded by a time in which these horses lived.
You see, just as this person is doing here, geologists have done with all the layers of the earth; they have simply dug them up wherever they can be reached in quarries, railway excavations, and so on. In geology, you learn that you use a hammer or another instrument to search for quarries everywhere in order to uncover what has been exposed in the mountains by landslides or similar events. You hammer everywhere, saw out one thing or another, and then you find so-called fossils in some layer. One can say that beneath our soil, layers have been preserved that contain animals that are completely different from those of today. And one can then figure out what the animals that existed in ancient times looked like by digging up the layers of the earth in this way.
This is not so unusual, because, you see, people actually underestimate the time it takes for something like this to happen. Today, in more southern regions, you find churches or other buildings; they are just standing there. You come across something — blimey, under this church, there is something hard, something that is not earth. You dig into it and find that there is a pagan temple underneath! Yes, what happened there? Relatively recently, the top layer on which this church or building stands was not there at all, but was brought in, perhaps by people, but perhaps also with the help of natural forces, and underneath is the pagan temple. What is now below was above. That's how it is. But in the earth, layer upon layer has been piled up. And one must find out, not from the way the layers lie, but from the way these fossils, these fossilized animals lie — and to this we must add the various plants — how they got into the layers.
But then the following turns out. You see, the following can happen: You find a layer of earth (see drawing, yellow); you find another layer of earth (green); you are able to dig into it (arrow) by some means. If you now look only at the layers, it seems to you as if what I have drawn in green is the lower layer and what I have drawn in yellow is the upper layer. You simply cannot get there; you cannot dig there, there is no railroad, no tunnel, or anything else that would allow you to get there. Then you realize: the yellow is the upper layer, the green is the lower layer. But you cannot say that right away; first you have to look for the fossils. Now, very often you find fossils in what lies above that must be older. For example, you find strange fish skeletons up there, and down below you find, say, strange mammal skeletons that are younger. Now the fossils contradict the location: the older ones appear above, the younger ones appear below. Now you have to figure out where that comes from. Yes, you see, it comes from the fact that some earthquake or internal tremor caused what was down here to be thrown up over what was above, so that this is what happened: if I were to place the chair over the table here, if that were the original position of the chair back and the tabletop here, then what would happen is that an earth tremor occurring here would cause the tabletop to flip over the back of the chair.
You see, this can be observed in a variety of ways: it has been turned upside down. And, as you will soon see, we can also know the following. One can ask: When did this overturning happen? This overturning only happened after these fossils were formed; otherwise, they would have to lie differently inside. So we know that this overturning, this rearrangement, occurred later than when these animals lived.
In this way, one comes to the conclusion that the layers of the earth should not be judged simply as lying on top of each other, but as having been rearranged. And look at the Alps, this mighty mountain range that stretches from the Mediterranean Sea to the Austrian Danube region—this mighty Alpine range, which is the main mountain range of Switzerland, cannot be understood at all if one cannot grasp such things. For in these Alps, everything that was built up in layers was later thrown into confusion. Often the lowest layer is at the top and the highest layer is at the bottom, and one must first search to find out how things were thrown into confusion.
Only when you take this into account can you determine which layers are the oldest and which are the youngest. And of course, today's science, which is based solely on the external aspects of this research, says: The oldest layers are those in which the simplest remains of animals and plants can be found. Later, the animals and plants become more complex—so the more complex animals and plants are found in the younger layers. When you get to older layers, you find fossils that originate from the fact that what the animals had in the way of calcium or silica inclusions has been preserved; the rest has dissolved. When we reach younger layers, the skeleton has been preserved. Strangely enough, however, fossils also form in other ways. These other fossils can be very interesting under certain circumstances.
You see, these fossils also form in this way: Imagine that there was once a simple older animal, an animal with a body, let's say with tentacles (white) at the front — I'm drawing it this big, but in the layers known from geology, it will usually be smaller. Now, this animal dies while lying on this soil. Let's assume that the soil is such that it cannot really penetrate the animal; this soil, so to speak, avoids any acid contained in the animal. Then something very strange happens; the earth in which this animal lies approaches the animal from all sides and envelops it (yellow), and a cavity is formed in the shape of the animal.
It has happened very often that such cavities form (green). The earth accumulates around the animal. But there is nothing inside, it does not suck the animal dry, but because the animal was shelled, such a cavity forms around it. Later, however, the shell dissolves, and even later, a stream winds its way through, filling the cavity (green) with its rock mass, and inside it, an impression of the animal is finely modeled with a completely different material, with a completely different substance. Such impressions are particularly interesting, because we do not have the animals themselves, but casts of the animals.
Now, you see, you must not imagine things to be so simple. Very little remains of modern humans, for example, with their relatively soft tissue structure, and relatively little has remained of higher animals as well. For example, there are animals of which only casts of the teeth have remained; one finds a kind of cast of primeval shark teeth that have formed in this way. Now one must have the ability to say to oneself: Every animal form has its own tooth shape — humans have a different tooth shape — and the tooth shape always corresponds to the whole form, the whole being. Now one must have the talent to be able to imagine, from the teeth that one finds there, what the whole animal might have been like. So it's not that easy after all.
But you see, by studying these layers, you also come to understand how the whole thing actually developed. And from this it simply follows that there were times when animals such as those we have today did not exist, but instead there were animals that were much, much simpler, that looked like our very lowly animals, snails, shellfish, and so on. But you have to know what has remained of these animals everywhere. Just think, the following could happen.
Suppose a little boy who doesn't like crabs steals a crab from his parents' meal and plays with it. He doesn't get caught and buries it in the garden. Now he has buried the crab in the garden. The whole thing is covered with earth; it is forgotten. Someone else has the garden later; he digs it up and notices something in one spot: strangely enough, he finds two small things that look like little calcareous shells. You know that there are so-called crab eyes, which are not eyes at all, but small calcareous shells that are inside the crab's body. These are the only signs that remain of its traces. Now you cannot say: these are fossils of some animal – rather, they are fossils of only part of the animal. In older layers, one can find structures that look like shells, especially in the Alps. They look similar; they no longer exist today, but can be found in older layers. One must not assume that these were whole animals, but rather that there was something around that has dissolved, and only a small piece of the animal remains.
Today's science pays little attention to this. Why? Because it simply says: this mighty Alpine massif shows that it has been thrown into confusion, the bottom at the top, the top at the bottom; the layers show this. But, gentlemen, can you imagine that with the forces present on Earth today, such an Alpine massif could be thrown into confusion in this way? The little that happens on earth today happens in such a way that, comparatively speaking, the earth is shaken up, that the earth is thrown a little from one spot to another; that is all there is today, this shaking up. If human beings lived to be seven hundred and twenty years old instead of seventy-two, then they would experience how, in their old age, they are already walking on slightly higher ground than before. But we live too short a life. Just imagine if a mayfly, which only lives from morning to evening, told us what it experiences. Since it only lives in summer, it would tell us that there are only flowers, flowers all the time. It would have no idea what happens in winter and so on; it would believe that the next summer follows on from the previous one. We humans are mayflies that live a little longer, but with our seventy to seventy-two years, we still have something of the mayfly about us! Well, the fact is that we see little of what is going on. And so one has to say: with the forces that are at work today, more is happening than humans usually see, but relatively speaking, all that is happening is that the soil is being washed up a little, that rivers are flowing towards the sea, leaving behind river sand, that the river sand then continues along the banks, that the fields are getting a new layer. That is relatively little. If we consider how something like the Alpine massif has been shaken and stirred, then we must realize that the forces that are at work today were once at work in a completely different way.
But now we must try to imagine how something like this can happen. Yes, just take any egg cell, an egg cell from any mammal. At first it looks relatively simple: surrounded by protein mass, with a nucleus inside (it is drawn). But suppose this egg cell is fertilized. You see, when it is fertilized, the nucleus does all sorts of things; it forms, very strangely, into a sum of spirals that rise up like a tail. This is how the nucleus forms. At the moment when these little balls arise, star-shaped structures emerge from the mass; the whole mass, because there is life in it, takes on form. Things are already different from how they are today on our Earth! Inside, there are already such inversions and overthrows as we see in the Alpine massif!
What could be more natural than for us to say: So the Earth was once alive, otherwise these inversions and overthrows could not have arisen at all! The present form of the earth shows us that in the time when there were no humans and no higher animals, it was itself alive! So that we must also say from this phenomenon: the present dead earth emerged from the living earth. — But only in this present dead earth can animals live! For just imagine if oxygen and nitrogen had not separated themselves in the air and had, so to speak, condemned hydrogen, carbon, and sulfur to a state of relative inactivity. We would then have to breathe something similar to the protein in a chicken egg, for that is what surrounded the Earth.
Now one could imagine, for example—because anything can happen in the world—that instead of our lungs, organs could have formed through which we could inhale such atmospheric protein. We can consume it today through our mouths. Why shouldn't something more like a lung organ have developed closer to the mouth? Anything can happen in the world. Whatever is still possible also comes into being. So, in humans, it is not actually a matter of the body as it is today. But just consider, gentlemen: when we look into the air today, we are looking into dead air. It is dead. In the past, the protein was alive. The air is dead; precisely because the sulfur, hydrogen, and carbon are gone, the nitrogen and oxygen are dead. We look into the light-filled air that is dead. This allows our eyes to be physical, and they are physical. If everything in our environment were alive, our eyes would also have to be alive. If they were alive, we would not be able to see anything with them, and we would be in a constant state of unconsciousness, just as we faint when our head begins to feel too alive, when we have all kinds of growths in our head instead of regularly formed organs, we also faint, first now and then, and later the number becomes so great that you lie there as if dead. So, as we were originally, we could not have lived with consciousness on this earth. Human beings could only awaken to consciousness when the earth had gradually died. So we develop as human beings precisely on the dead earth.
That is how it is, gentlemen! It is not only true of nature, but also of culture. If you look again at what I said, that there could be pagan temples below and Christian churches above, these Christian churches relate to the pagan temples just as the upper layers relate to the lower layers; only in one case we are dealing with nature, in the other with culture. But one cannot understand how Christianity developed unless one considers how it developed on the basis of paganism. The same is true of culture. Here, too, one must observe these layers.
Now, I told you that human beings have always been there, only not as physical beings, but as more spiritual beings. — And that in turn leads us to understand the real reason why human beings did not develop as physical beings earlier. You see, I told you that today there is less nitrogen, oxygen, carbon, hydrogen, and sulfur in the air. Today, we ourselves combine the carbon we have within us with the oxygen we breathe in, connect the carbon with the oxygen, and expel the combined carbon and oxygen, which is called carbon dioxide. So we humans live in such a way that we inhale oxygen through breathing and exhale carbon dioxide. That is what our life consists of. As humans, we would have long since filled the earth and the earth's air with carbon dioxide if it weren't for something else. That something else is plants; they have the same hunger for carbon as we have for oxygen. Plants, in turn, greedily absorb carbon dioxide, retain the carbon, and release oxygen back into the air.
You see, gentlemen, how wonderfully this actually complements each other! It complements each other splendidly. We humans need oxygen from the air, which we breathe in; we give it the carbon we have inside us, breathe out carbon and oxygen together as carbon dioxide. Plants breathe it in and breathe out oxygen again. And so there is always oxygen in the air again.
Yes, that is how it is today, but in the development of humanity on earth, it was not always so. When we find the ancient beings that lived there, which we can even find in the fossil layers, we say to ourselves: Yes, they cannot have been like our animals and plants today, especially not like the plants of today, but all these beings that were originally there as plants must have been much more similar to our sponges, fungi, and algae. But there is a difference between our fungi and our plants today. The difference lies in the fact that our plants today absorb carbon and use it to form their bodies. When such plants sink into the earth, their bodies remain there as coal. What we dig up today as coal are plant bodies.
Gentlemen, everything we can investigate in relation to what plants originally lived shows us that today's plants, including those plants that once supplied us with coal, which we now dig out of the earth, are made up of carbon. But much earlier plants were not made up of carbon, but of nitrogen. Just as our plants today are built from carbon, these plants were built from nitrogen. How did this become possible? You see, it became possible because, just as carbon dioxide is exhaled by animals and humans today, in ancient times a compound of carbon and nitrogen was exhaled. Today we exhale a compound of carbon and oxygen, but in the past a compound of carbon and nitrogen was exhaled. But, gentlemen, that is hydrocyanic acid, the hydrocyanic acid that is so terribly poisonous to everything that lives today, cyanide! This poisonous hydrocyanic acid was once exhaled, and it prevented anything like what lives today from coming into being. This hydrocyanic acid is a compound of nitrogen and carbon. The carbon is not yet accepted by these fungus-like plants, but the nitrogen is accepted. These ancient plants built themselves up from nitrogen. And the beings I told you about, these bird-like creatures and these clumsy animals I told you about last time, exhaled this poisonous acid, and the plants around them took the nitrogen and formed their bodies, their plant bodies, from it. So we can see here, too, that the substances that are still there today were used in a completely different way in ancient times.
And that is precisely what I once spoke about from an anthroposophical perspective; I have already told the gentlemen who have been here longer: in 1906, I had to give lectures in Paris on the development of the Earth, the origin of humankind, and so on, and there I had to say, based on the whole context: Can we still find anything today that indicates that carbon and oxygen did not always play the role they play today on Earth, but that nitrogen played such a role that there was, in a sense, an atmosphere of prussic acid, of hydrocyanic acid?
Now you know the following: there are old people and small children. There may be a seventy-year-old standing next to a two-year-old child — one is a human being and the other is a human being. They are standing next to each other, and the one who is seventy years old today was just like the little child sixty-eight years ago. Things of different ages stand side by side in life. But just as it is in human life, so it is in the world. There, too, older things and younger things stand side by side, so to speak. On our Earth, with what I have just described to you, what you still see today, there is something truly aged, even almost dead — if one does not take into account the life that has sprouted anew — something almost dead. But alongside this, there are younger formations in the universe that are only just becoming what our life is today. Comets, for example, must be viewed in this way. We can therefore know that comets, because they are younger, must still have conditions that correspond to their youth. Just as a child stands in relation to an old man, so comets stand in relation to the earth: if the earth once had hydrocyanic acid, then comets must still have hydrocyanic acid; they must have cyanide compounds! So that if you were to lick a comet with your present-day body, you would die immediately. Of course, it is diluted hydrocyanic acid that is inside.
Now, you see, I said this in Paris in 1906, that this follows from spiritual science. Well, at first, those who recognize spiritual science accepted this; one can even be surprised at such a thing. Then later, some time after that, another comet appeared. By then, the necessary instruments were available, and through ordinary natural science it was discovered that comets really do contain cyanide, hydrocyanic acid — just as I had said in Paris! That is how things are confirmed. Of course, because that is all they hear, people say: Steiner said in Paris that comets contain hydrocyanic acid, and afterwards it was found — that's a coincidence! — That's what people say, because they know nothing else: it's a coincidence. But I have now told you why we must assume that comets contain hydrocyanic acid. So you see, it's no coincidence, it's real science that led to this discovery! It's just that sensory research will only confirm this later. And so people could already see what is in anthroposophy: everything will be confirmed later. Even today, outside the anthroposophical movement, it is often found in a slightly different way, but it was already given by anthroposophy many years ago.
Yes, there are even other things, gentlemen. This is something that could be investigated scientifically today. I always say: if people could really travel out to a star, they would be very surprised to find that it looks different from what they imagine it to be based on today's earthly concepts. People imagine that there is some kind of glowing gas inside. But you don't find that out there at all. Where the star is, there is actually empty space, but an empty space that immediately sucks you in. There are suction forces there! It immediately sucks you in and shatters you. And if you proceed with the same research as consistently and have such an unbiased way of thinking as we have here, you can also come to the conclusion, using complicated spectroscopes, that there are no gases, but rather suction space. — And some time ago, I gave certain people the task of using the spectroscope to examine the sun and the stars in order to prove, simply through external experiments, that the stars are hollow spaces, not glowing gases. And this can be proven. But the people to whom I gave this task were terribly enthusiastic at first: Oh, something is being done! — But sometimes this enthusiasm fades; they have waited too long — and a year and a half ago, news came from America that they are in the process of examining the stars and are gradually discovering that the stars are not glowing gases at all, but hollow spaces! There is no harm in that happening. Of course, outwardly it would be more useful to us if we did it. But that's not what matters; as long as the truth comes out.
On the other hand, however, it is precisely through such things that one can see how anthroposophy actually wants to work together with conventional science. And so it certainly wants to work together with conventional science, for example in relation to the layers of the earth. One certainly accepts what conventional science has to say about the upheaval and confusion in the Alps. But one cannot agree with the assumption that the forces that are still there today are being thrown around in this way; rather, there were life forces there that could only throw this living matter into confusion! — So, anthroposophy is truly already present in conventional science. Conventional science only wants to stop where it is too lazy to really approach these things.
Then on Wednesday at nine o'clock, continuation.
