### 33. Natural Science at a Crossroads

More than in any other form of learning, however wise, it is often in simple myths and legends that we find deep, profound wisdom and truth. It seems as if an ancient truth from the human breast were speaking to our soul when we hear a very simple but deeply moving Mongolian fairy tale. This fairy tale goes something like this: There is an old woman. This old woman has only one large eye at the top of her head, and no other eyes with which she could see. She goes all over the world, and everything she encounters along the way, she picks up: every stone, every plant, everything, everything; and then she takes what she has picked up to her only eye to look at it, and when she has looked at it, something like a tremendous horror expresses itself on her face. Then she throws the object far away from her. This story goes on to tell us: This old woman once lost her only child, and now she searches the whole world for this only child, believing she will find this child in every stone, in every object she encounters. When she has raised an object to her eye and once again realized that it is not what belongs so deeply to her, disappointment paints itself on her face and she throws the object away.

Now, if we wanted to interpret fairy tales and legends, we could find a deep wisdom in this fairy tale, which is rooted in the most primitive folk minds. We don't want that now. In such fairy tales, one can find many, many interpretations; but it seems to us that this fairy tale expresses a yearning in every human breast. Every human being, when he becomes clear and distinct about his deepest soul values, feels that he must seek something in the whole world, something that is most deeply related to the innermost part of his soul, something that he must believe can manifest itself in every stone, in every being. And every human being feels that what he is actually seeking cannot be seen with the outer eyes and perceived directly. Every human being feels within himself a higher spiritual eye with which he walks through the world, and he senses that what meets the outer senses are only the means of expression for something that lives behind them, and so he walks around in the world like that woman, looking at every object. As long as he only looks at it with his external senses, it gives him something that, when he holds it up to the eye of his longing, deeply disappoints him. And he throws it away, saying to himself: Again, again not what I feel, what must live in all external things. For it is indeed the spirit behind all sensual physical beings that man seeks unalterably and perpetually, the spirit of which he knows that it lives within him, and of which he knows that he must somehow find it behind external objects as well. It is spiritual science that points man to what is behind sensual things and what can truly satisfy his spiritual gaze.

This spiritual science, if we look at things objectively, has, despite its short life, found a fairly wide distribution among the educated of our world in recent decades. Nevertheless, the strangest prejudices are in circulation among many people who only deal with this subject superficially. We always hear: This theosophy wants nothing more than to transplant some oriental worldview into Europe. We hear that it is a sect, that it leads to the most blatant superstition.

Not a single trace of this is true. However, it is true that if a person wants to see what this spiritual science can give them, they have to delve deeper and deeper into it. If it really gives the spiritual, if it satisfies the human longing that has been characterized, then it is more than what mere curiosity can satisfy. It is something that man needs for his life. It makes it clear to man again that in the spirit is the origin, the germ, the source of everything, including the physical, and if that is the case, then with the spirit it gives man strength at the same time, the source of life in general. Those who engage with it more deeply find this to the fullest extent.

Nothing is more fundamental, more significant for this spiritual science than the proposition that the spiritual in us, our thoughts, perceptions, feelings, are facts that have a deep effect and significance for our outer life. If we apply this specifically, if we single out one of these facts, we can say: true, genuine thoughts of the spirit give a person satisfaction, inner harmony. But inner harmony and contentment mean, if the spirit is really power, health in its effect on the physical organism, while doubt, the isolation from the spiritual world, gives man inner insecurity, hopelessness, inability to work. It gnaws at his deepest being. And because thoughts are facts, doubt and hopelessness affect his health in such a way that they weaken it. This is an assertion at first. But anyone who delves deeper will gradually be convinced of its validity.

Nowadays, there are many obstacles for people who want to approach this spiritual science. Anyone who is familiar with this spiritual science is by no means inclined to underestimate the serious obstacles that stand in the way of a person's understanding of spiritual science if he looks at things impartially. Among these manifold obstacles, there is something that is directly related to the greatest advances and most significant achievements of our age: natural science. But not to the facts of natural science! To claim that the humanities, or any kind of pursuit of truth, could come into conflict with the facts of science is madness. Facts are facts. And there can be nothing that somehow comes into conflict with the facts of science.

But when we talk about science today, for most people who lean on this science, it is not just about facts, but rather about a confession, a kind of belief that has been gained from science. And in particular, it has been the last 60s and 70s of the last century that have gradually produced a kind of scientific confession for many. This confession is expressed in the fact that there are many people who say that speaking of spirit, of a divine-spiritual background, is impossible for today's man; childish-fantastic ages spoke of spirit or soul. It is impossible for today's mature humanity to speak of these things, because scientific facts force us to do otherwise. And that which is spreading today as a kind of scientific religion and gaining more and more followers captures the imaginative life of many to such an extent that it is simply true that many who are caught up in this captivity must regard what spiritual science has to say as pure nonsense, as mere reverie.

The humanities scholar must understand what is at stake here. We can certainly experience the following. The humanities scholar comes forward with what he believes he can say based on his faithful observation of the spiritual world, with manifold teachings about what lies beyond the physically perceptible. These things have often been spoken of here, spoken of what we call the higher aspects of human nature, of the fate of man between death and rebirth, of worlds other than the physical. What is said here must seem like fantasy, if not something much worse, to many who today profess some kind of scientific doctrine. And today our consideration is specifically devoted to this fact, to the fact: What must someone who, over the last sixty years, has developed out of what is not directly given by the natural sciences, but what has developed on the basis of them and professes them, what must he think of Theosophy or spiritual science, or what can he easily think of them?

Before we go into the position of these contemporaries, who believe they have a scientific creed, we must characterize the essential point of the points of spiritual science in question. The point of spiritual science is to show in everything that the spirit is the original, matter is the derivative, that is, what appears as the effect of the spirit. So, for the spiritual researcher, substance, matter, sensuality is also spirit, but like spirit in another form. Take a child, for example. It comes to you with a piece of ice. You say to the child: This is water, real water, just in a different form. The child will say: Yes, but this ice is not water! — Then you will say: If you familiarize yourself with the nature of ice, you will understand it. Thus, when someone has matter, something sensory, before them, the spiritual scientist will say: This is spirit in another form. The materialist, on the other hand, will say: But this is matter. And the spiritual researcher will say, just as you would answer the child: You must first familiarize yourself with the extent to which matter appears in another form than spirit.

And this, which has been presented to your soul in a very abstract way, is what spiritual science seeks to explain in detail, for example, to show that what you recognize as a sensual person, see with your eyes, touch with your hands, that this outer material person is nothing more than the result of a spiritual person. Just as ice is water in a different form, so is the physical person a spiritual person in a different form.

Now, of course, when we present something like this in a few strokes today, we have to remind ourselves of what has been said in other lectures. It is difficult for those who have not heard these lectures. This spiritual science shows that if you go further and further back in time from the present, you will find other forms in the course of development, ever simpler and simpler outer physical human forms. These physical bodies of man would appear to you, if you go back far enough, more and more simple, until, if you go back far enough, you would find very simple, primitive human forms. But the further you go back, the more primitive the physical forms become, the more you find an invisible human form linked to this physical form. And if you go back even further into the times when the physical human being became smaller and smaller, the physical body becomes inconspicuous, but the spiritual human being is there, and that is the creator of this physical human form. And if you go back even further, the human form disappears altogether, and you come to the original human being, out of whom the physical one has concentrated. He is a spiritual human being.

Let us visualize how the formation of man happens now, through a comparison. Take a certain amount of water. In this, let a small amount of it freeze into ice. Then there is a small amount of ice in the middle and water all around. Now let more freeze. Then you have a more complicated ice shape. If there is already less water than before, then the water is combined into ice. The more water that freezes into ice, the less water remains. More and more ice should be created until we have almost allowed all the water to freeze into ice, so that what used to be water is now expressed in the hard, tangible form of ice.

This is roughly how we have to imagine the development of man if we stick to the comparison. We can only see the water, we can no longer see the spiritual man. Out of him begins to shine the first primitive, original form of man, which stands at the lowest level of organization. All around is this spiritual man, he condenses. This is how it continues to this day. Our present human being, as he stands before us, has been formed out of the spiritual man into the physical. The spiritual form has become more and more material. Today's human being is the expression, the revelation of the invisible man who has become visible.

Now we take up another train of thought, assuming that we had not allowed just one lump of water to solidify, but a number of them. We would have allowed the first one to solidify, then we would have taken it out. It now remains as it was and shows us the stage of development that existed at a certain phase. Now, if we had allowed a second lump to solidify at a higher level, we would have taken it out. It remains as it is. A third one as well. Finally, we can now present the whole long series of developments, where more and more water freezes into ice, until finally a point is reached where there is only one lump of ice. We have bits of ice that have lost the ability to attach other bits of ice because we have separated them from the water. This is how, in the sense of spiritual science, one imagines the development of man in his relationship to the animal world.

Once upon a time there was a spiritual man; he originally formed primitive bodies for himself. The part that retained and further developed the spiritual man reached up to today's humanity. But where a stage of development broke away, it stopped. Thus, on the first stage, when the spiritual man had developed the primitive form, a small gelatinous ball broke away, remained as that piece of ice and formed today's lowest animals. They lost their spiritual foundation. At a later stage, creatures remained behind that took the form of worms. Later still, others took the form of fish, then amphibians and so on, until finally, in a time that is not long for the spiritual researcher, the ape family emerged from the spirit, so that it could no longer keep up. Man has also progressed beyond this stage.

So you can never say that man derived from any form that now exists. Rather, it is the other way around: the forms outside, which surround you everywhere, these forms present us with developmental epochs that man has overcome because he retained the original spiritual human being within himself, because he did not tear out what had become physical from the spirit. When man looks out into his surroundings, he says to himself: I am the first in our evolutionary series; I was already there at the time when the most primitive animals had not yet appeared. I have gone through all these stages; I see my stages in my surroundings.

This is how the spiritual researcher thinks about the development of man, who, as a spiritual being, descended from the bosom of the Godhead, who has progressed while the animals crumbled away and had to remain at an earlier stage because they lost the source. When we look at any physical being, we see how it is formed out of the spirit.

But the spiritual researcher goes further. He sees in everything around him, not only in living beings, in all matter he sees, as it were, solidified spirit. Atoms are nothing other than solidified spirit. For him, the spiritual is the original, the material the derivative. When we see a stone outside, how should we think of it? That even this stone is condensed spirit.

This view has nothing to do with the extreme view that wanted to deny matter. By tracing all matter back to spirit, one does not deny it, because existence does not depend on not seeing spirit, but on becoming aware of the effect. Of course, the condensed spirits in matter have different properties than the spiritual beings themselves; that much is clear. It is only necessary to think these things through to the end. The confessions that have emerged from natural science since the 1960s are now directed against this basic fact of spiritual science. They only accept the sensual as the original and do not want to recognize the spiritual.

Who does not remember the two other trains of thought that confront one in today's world when what has been said is mentioned! Who does not remember what is emerging today as a monistic theory of evolution, whereby animals related to humans are not understood to have split off, but rather as if only the lower animals had originally existed, so that humans are the composite product of the individual building blocks of animals? It is pointed out: once only simple organisms existed. So now, according to the other theory of evolution, a higher being should have developed up to man. So man would then have simply arisen from the lower animal being in terms of his entire inner meaning.

And who does not remember the other thing that is said? Let us look at an object as it appears to us. What does it consist of? Of the smallest parts of matter, molecules, atoms, they say. And these smallest particles of matter are the only truly real things. All beings have come into being only through the interaction of these [particles of matter]. These two things are so certain for many people today, they are such suggestive concepts that many people cannot associate any sense with other things. They must be given their due. These two lines of thought are connected with the most fruitful lines of development in the nineteenth century.

We do not want to go back very far, but we will recall two fundamental facts of natural science, facts that are related to each other, the two great achievements of Schleiden and Schwann. Schleiden came to the conclusion in his studies of plants that they consist of the smallest parts, the cells, that every plant body is composed of cells, the smallest living organisms, and from there the thought takes hold: one has actually studied the plant when one has studied the nature of the cell, because these are the actual reality. The plant is only a composition of them. When Schwann found the same for the animal kingdom, this view that you can recognize a being by studying the parts of which it is composed, was also decisive for the animal kingdom. The wonders that opened up to microscopic research were admirable. What has been found through it is something great and powerful. But there were other things to come. The great discoveries in the fields of chemistry, physics, and biology came.

I will mention just a few: Darwin made a great impression by showing the transformability of animal and plant life. With tremendous diligence and great scientific rigor, he compiled facts that revealed the relationship between animals and plants, all the way up to humans. We need only recall how, through spectral analysis, man was able to look out into the heavens to find that the substances of the heavenly bodies are the same as those of our earth. The discoveries of Kirchhoff and Bunsen, which revealed the composition of the universe, are rightly called great. But these were also very much facts that bound these human minds to the material.

Those who can still look back a little on the development of intellectual life know how it happened, how, before Schleiden and Schwann, attempts were made to understand the whole plant by applying intellectual powers, and how it then became clear that the primeval organism was present in the cell organism that could still be perceived by the senses. The eye has conquered such wonders that man believed there was nothing more. Through such a thing as spectral analysis, the human mind had to be bound to the material. He had looked into the material events of the universe. It was not surprising that he forgot that there is also spirit in it, so that these conquests at the end of the nineteenth century in particular gave rise to atomism, the view that one only has to go to the smallest material and ever smaller, and find the explanation in the smallest material.

If this had remained a mere theory, it would not have had such a great significance for the spiritual path of humanity. But it could not remain that. With those bold minds of the nineteenth century, who unashamedly accommodated themselves to crass materialism, we see where such material thinking must lead. There we have minds such as Büchner's, Moleschott's and so on. Today they are already much maligned, but that is a half measure, not the whole. People say they have moved beyond them. They abandon the most crass assertions, but stand on the same ground as they did. They do not see that the ground has only been more consistently developed.

Only spiritual science is called upon to overcome this. We need only recall what Carl Vogt said, that thoughts are exudates of the brain, like any other metabolic process. Just as the kidneys exude certain substances, so the movement of the brain particles exudes thoughts. Something like that cannot remain a theory if it is believed. If that is the case, if a person's thoughts and feelings are products of the material movement of the brain parts, then with death, when the materials that make up the human being dissolve, all of the innermost essence of the human being disappears, and there is not the slightest possibility of speaking of spiritual and soul entities that outlast the human being. If the smallest material parts are the essence, then Vogt's way of thinking is consistent: when a person is buried, he disintegrates, and nothing should remain of him. These thinkers drew these conclusions and were basically much more consistent than some who wanted to be idealists at the time and who actually thought materialistically in their hearts. A dispute between Vogt and a Munich scholar who held on to soul and spirit and published articles in a Munich magazine in which he opposed Vogt was characteristic of the way in which the way of thinking was eaten away by materialism at the time. Wagner was the man's name, and Vogt wrote a spirited pamphlet against him. It was easy to refute the man with the spiritual doctrine and the materialistic way of thinking. For how did this Wagner roughly imagine the transition of the soul from parents to children? As if a measure is divided into eighths. That is, to believe in a soul substance, just as if one could weigh it. Something like that was easy to refute. That is what matters; not whether you have a spiritual doctrine, but whether you can really live in the spirit. Those who believed spiritually at the time could not do that. They were so firmly held in the spell of the material achievements of that time that, little by little, everything around us became an expression of the movement of the smallest material parts for people.

In the field of living beings, people were not satisfied with cells; instead, they were made up of atoms. From then on, life was nothing more than a complicated process of movement of the smallest parts. Complicated movement was then the movement in our brain; and that, as this movement presented itself, was human thoughts and feelings. And even those who only studied physics and physiology in this field twenty or thirty years ago experienced something that has now become rarer, what is called the reduction of all experiences to processes of moving atoms. They said: Besides us, there is only matter. What do you call color? It is nothing more than a certain movement of atoms that vibrate. The vibrations reach the eye. One form of vibration, one speed appears to us as red, the other as blue, the third as green. Red, blue and green are nothing more than subjective impressions of what exists outside. And out there are only vibrational processes in the smallest ether particles. If you turn your eye so that what vibrates outside can reach you, you become aware of it as the impression of red, blue or green. If you turn away, then nothing else is present but a vibrating process.

Then the students were tormented with the mechanical theory of heat. That which burns your fingers is nothing more than a subjective impression. Objectively present are the vibrating atoms. Imagine a container with billions of the smallest globules of a gaseous body. They vibrate in confusion, moving, bumping into each other, colliding with the walls and back again. This tremendous, structured form of motion is what manifests itself as a sensation of warmth when we put our hand down. Nothing of what we experience is external to us, but only the motion of the smallest parts. There is no warmth, there is no light, only the motion of the smallest parts. There is no electricity, only the motion of atoms. For those people, atoms had become the only reality, the absolute existence. If we dissect a human being, everything we see is a subjective impression. The human being before us is nothing more than an enormously complicated process of motion. What remains are the atoms, which, when a person dies, merge into other motion processes and form new groups. The eternal, the immortal, became the atom!

Now chemistry had found a number of substances, some 70. These substances were characterized by the fact that they could not initially be broken down into simpler ones. Water can be broken down; oxygen cannot, so it is a simple substance. What was such a simple substance? In their way, they were something eternal; but how eternal? Each element represents the cohesion of the smallest parts. These were jumbled up in the most diverse ways in the universe, here simpler, there more complicated. But the world was always only the jumble of the 72 different “eternal” elements. These were the only reality. At most, the forces were still accepted. For those who think in materialistic terms, the following must apply: an eternal thing is the individual atom. It must have existed since time immemorial and must remain in existence into time immemorial, that is the eternal. The indifferent atom, the unconscious atom, that is the original building block. And if everything is only the jumbled confusion of atoms, it is only logical to regard everything else as appearance and vapor, as something insubstantial that rises like a fog. This is a concept that has great suggestive power. There have always been people who knew what an enormity it is to assert the eternity of matter as the cornerstone of all worldviews. Du Bois-Reymond's “We cannot know” caused a certain stir when it was spoken at a natural science conference. What did he mean by that? He said: Yes, suppose you had got so far as to know, when you entertain a thought, how the atoms in your brain move. Have you grasped why certain atoms move one way and others another? What you experience inwardly: I see red, I smell the scent of roses? — He had taken up a saying of Leibniz: From a certain point of view, the brain is a material composition of atoms. — Let us assume, says Du Bois-Reymond, we could see its composition, let us assume that the brain were so gigantic that you could walk around in it, that you could understand the whole mechanism of the brain. Imagine that someone tries to understand: If there is such a movement, what this person, to whom the brain belongs, actually experiences in his soul during this movement, whether, when the parts move in one way or another, he has this or that sensation! We see movements, we see mechanical processes! We can never perceive the transition from this mechanical process to the inner experiences of the soul.

Du Bois-Reymond went even further. He said: If a person is sleeping and you examine the movements of his brain, the fact is not present in the person: I see red, I smell the scent of roses. You can understand this sleeping person, he said. But as soon as he wakes up, scientific understanding of the mechanism ceases.

This was something where theosophy or spiritual science looked in through the window of the natural world. The spiritual researcher shows that when we sleep, our physical and etheric bodies lie in bed, and outside of them is the astral body with the ego, so that the spiritual and the soul-like human being are lifted out of the physical body. What remains, Du Bois-Reymond finds explainable. However, there is still an error in this: life was overlooked. You see, here you have the first outpost of theosophy, but at the same time something that expresses the desolation of such a scientific view: we will not know, says Du Bois-Reymond. Even if it is true that one cannot understand, there is never any other explanation than that which arises from the movements. This means renouncing any explanation of the mind.

There is another matter. A chemist, Ostwald, spoke at the naturalists' meeting in Lübeck about overcoming materialism from his chemical-physical point of view. He showed that there is no sense in speaking of matter. He made a rough comparison. If someone hits another person with a stick, it does not matter to the stick, because the stick is material. What you feel, he said, is the force that is acting on you. So Ostwald tried to establish the view that everything consists of individual forces. The force that we perceive is what matters.

What were atoms? In the past, they were the smallest parts. For Ostwald, they were a small combination of forces; when they crystallize, they become atoms, matter. There we have the first step away from atomism. A person like Ostwald is not capable of rising to the view that everything is spirit. He said that everything is force, the parts of matter clenched together out of force. That was speculation. But there were innumerable reasons for it. In those days one could remember something that had been said long ago. And it was precisely I who pointed out the following in the sharpest possible way: Goethe, who is as great a naturalist as he is a poet, said: If only people did not look for anything behind appearances! The phenomena themselves are the teaching.

For a view of the world that is held in the spirit of Goethe, the following applies: What we perceive is reality. What are atoms for such a view? What is an atom? Can we associate an idea with it? What we imagine are the properties of things. We perceive things through their properties. Does the atom have such properties? Does it have a color? According to the atomistic view: no. Color, after all, is only produced by motion. Do they smell, do they taste? No! Because this, too, is only produced by motion. Do they show a certain temperature? No. All the properties around us must be denied to the atom. What is the atom for healthy thinking without properties? A fantastic construction, nothing more. Every property is denied to that which lives in the environment. The atom is something imagined as a lump in space, but it is denied all the properties it would have to have. That is the characteristic of the atomistic theory, of this basic tenet of materialism, that this theory is the most fantastic thing one can think of, pure dreaming. What one has recognized as the eternal is invented; it contradicts all healthy thinking.

Materialism attempts to conjure up such a fantastic reality in space. Without realizing it, materialism has built up the most blatant superstition. There is no difference between fetishism, which worships pieces of wood, and materialism, which worships small material lumps. The “savage” at least sees his piece of wood; the materialists imagine billions of little idols that can never appear in experience. Atomism has set up the idolatry of the atom, built on pure fantastic thought. The 72 elements exist for us insofar as they have properties. If we imagine them as consisting of atoms, then this falls prey to the most blatant materialistic superstition. All those jumbled-up atoms, all those chess pieces are inventions, are the fantastic basis of a thought.

Now, as I said, a person like the chemist Ostwald had at least pointed out that it makes no sense to speak of a pure substance, that everything dissolves into energy. We perceive energy, we do not perceive substance at all.

That was the situation in the 1980s and 1990s. Since then, things have changed completely. Until then, despite all the efforts to overcome materialism, one had to rely on sound thinking. Now, although this is the surest way to overcome it, it does not help much in our age. Anyone who, like the person speaking to you, has had to think through all the big formulas with which, for example, the red light rays have been calculated – movement of the ether atoms – anyone who has had to watch as everyone believed that the waves of the ether move in such and such a way, and then you perceive red; when, as in a vessel filled with gas, the molecules are thrown back and forth, then this degree of warmth arises, and so on. Anyone who has seen this knows something about the physiology of these things and knows that it can be difficult to achieve anything with healthy reason and real spiritual science. That was the case in the early 1890s. Today it is different.

A saying made by an English thinker, a physicist, and a good one at that, Minister Balfour, is extremely curious. He is an extraordinarily astute physical thinker. He said: If we want to think about what an atom is according to the newer views, what is the atom? He saw in it something that solidified out of flowing electricity, similar to how ice solidifies out of water. Balfour saw something more in the atom than Ostwald did. He saw flowing currents of electricity in which the individual particles of matter arise out of condensed electricity. So atoms are actually condensed electricity. You see, we still do not have a healthy view of the physical as condensed spirit; but we are now at the point where we can hear that the physical is something condensed. Think of the tremendous progress! What was electricity just a short time ago? Atom! The little fetishes had movement and the expression of that was electricity. Now the atom had already become condensed electricity. This is the real thing. That is an interesting turnaround. What was this turnaround based on? It was not based merely on the experience of the spiritual researcher or on sound thinking, but on specific experience. Physics itself, in its progress, had forced people to think in this way. This includes the phenomena observed in glass tubes through which electricity is conducted after they have been pumped dry – Crookes tubes. These phenomena led to the realization that what flows in such a tube is flowing electricity; that electricity flows in space at all. What was previously only a property was now something real.

Of course, it didn't all happen in one go. For the humanities scholar, heat is just as real as electricity, and light as well. Matter comes into being just as much through the solidification of light and heat as through the solidification of electricity. In twenty years, it won't be nonsense to say this. They will speak of what heat and light are, they will no longer claim that these little fetishes of atoms are the original, but solidified properties, solidified perceptions. What is around us is an emanation, a manifestation of the mind. Today this is still nonsense to the physicist, in twenty years it will be a fact.

This is the way to gradually arrive at the realization that all matter is solidified spirit. Physical thinking is moving directly in this direction, which leads to seeing spirit as condensed matter. This direction continues in this way. It then causes materialistic thinking to rack its brains. But it must be said: today, for materialistic thinkers, spirit does not so easily break away from the atomistic way of thinking. People have noticed that when chlorine and copper are mixed, something strange happens. In their view, chlorine is an element consisting of vibrating atoms; and these atoms would be something original. The copper atoms would be something original again. When the compound is formed, the atoms are pushed into each other, and then chlorine copper is formed. But now something strange happens. When chlorine and copper really combine, it happens with a fire effect. Heat occurs. This is something just as real as copper and chlorine. That it is something very real is shown when we want to separate the chlorine copper again. Then we have to reintroduce the heat, the same amount that was taken out.

Certain people who cannot get away from materialistic atomism have considered this. They came up with the following: Now, if we have chlorine on its own and copper on its own, which consists of atoms, then we have to think of these atoms as sacks that are puffed up by heat; and now, when we bring chlorine and copper together so that they combine, the heat is expelled, and now the empty sacks are pressed together in a jumbled fashion. When the bodies are put together, the sacks are squeezed out. When the elements are driven apart, the heat inflates the sacks.

You see, the atom has already disappeared, heat has become something very real. If we don't want to talk about sacks – the materialists did that themselves, we might have used the image of a balloon – then we have to say: if you separate the shells again, they will be filled.

What we see here is that what actually makes up the atom has already melted down to a very small size, to the shell. What gives the atom size is the heat it absorbs. This is extremely interesting. We are not far from a time when the skins will finally have been removed. For why should we not be able to imagine that if heat can puff itself up, it can be dispensed with altogether? Why should it not be conceivable to imagine the atom as frozen heat? We will come to that. Let us consider further. Even more interesting is the next step that science has taken. After the point where the atom had literally dissolved into flowing properties, came what begins with Becquerel's discoveries, which led to the magnificent and powerful discoveries in this very field, to the discoveries about radium. What do we have before us with this? We do not want to decide whether the ideas to which the physicists have been led are correct. It is our responsibility to establish that the physicists were forced to a crossroads by the phenomenon of radium. Radium emits various types of rays, electrical and so on, the effects of which can be seen on a photographic plate. But above all, it emits what is called emanations. These emanations have certain properties, properties that differ from radium itself, but are similar to it again, that dissipate over time, so that the emanation merges into something else. It throws parts of its own substance out of itself. These lose their properties and become something else. Physics has even had to accept that it has been proven that this emanation transforms into helium. Oh, what do we have now! Something flows out of the element radium and has different properties, something flows out and turns into an element again. This led chemists to say: the atom itself decays, decays into something completely different, so that it can turn into a completely new atom, even into a different element!

Imagine what that means! The parts of an element, which are called atoms, should be the most solid. Now, however, the experiment shows that these atoms crumble under our hands and become something completely different. This is something like the realization of the alchemists' dreams, that one substance can be transformed into another! Today, all this is still in its early stages, but already scientists are forced to say to themselves: the atom is not something original, it has come into being and will dissolve again. Long ago, atoms did not exist at all, although people spoke of them as the smallest fetishes. Gradually they came into being and will pass away again, as radium shows by the way it gradually crumbles its atom. Today, the physicist's atom disintegrates at our very hands. We shall no longer be able to speak of the atom in the old way. This is something different from what Ostwald brought. He still relied on conclusions; today the facts already speak; today the world of facts itself destroys the fantastic structure of the “atom”.

This brings us to an important point. Imagine the consequences of the atom being scattered, this firm support. It dissolves not only in thought, but in appearance, in space, in fact. The atom ceases to be before our eyes what it has been presented as. As ice melts again, so does the atom. Today, materialistic thinkers cannot go far enough; they can imagine that electricity accumulates; but the path leads to seeing that the original is the spirit. That is what the first step taken today is towards.

Thus, today, natural science, if it wants to understand itself correctly, stands at the beginning of the way of thinking that leads directly into spiritual science. It cannot help itself. When the mantle falls, the duke falls after it. What has led to the materialistic theory of evolution are thoughts that could not get away from matter. It sees human beings as a composite of animal species. Once we can grasp that what happens outside in the physical world comes from the spirit, then we will also be able to comprehend the way of thinking that was discussed at the beginning, of the spiritual primeval man who has become denser. Comprehension depends on our thinking habits. Physicists will force people to see spirit condensed in all material things. Then, when it is known that the atom is not eternal but has come into being and is changing into spiritual substance, it will also be possible to understand that man comes from spirit and goes to spirit. All this will lead to such a conclusion. What is happening today in the world of natural science must be viewed from within. Those who speak of it cannot yet renounce this tendency of development, which is afflicted by materialistic ideas.

But the facts guarantee that natural science will lead to spiritual science, that both will celebrate reconciliation. Spiritual science is something that must be presented to people in order to proclaim the spirit as the cause of the physical. Spiritual science will be needed when natural science can no longer go forward on its own; then natural science will be ready to merge into spiritual science. The latter is the outpost that establishes what people will need to know when the facts are ripe to unite with the spiritual-scientific facts. By itself, natural science would lead to the incomprehensible. At most, one would see solidified electricity in the atoms. To understand the final consequences, spiritual science is needed.

When we look back over centuries of thinking and feeling, we have to say that a hundred years ago, what we call natural science was just on the way to descending into the coarsest materiality. In the middle of the nineteenth century, the lowest level had been reached. In Vogt's saying that thought is a secretion of the brain as bile is a secretion of the liver, it had reached the point of extinguishing all spirit and explaining it as subjective appearance. Natural science was on this path; it was not ripe to turn its gaze up to spirit. Where was spiritual science a hundred years ago? It was immersed in abstractions, in concepts that shine deeply into the spirit. But there was one thing it could not do: bring down the great concepts of the spiritual world to the level of direct comprehension of what appeared externally.

Today we have a natural science that has plunged into the material, where the atom itself speaks, a natural science in which the atom disintegrates at our hands. We have spiritual science in theosophy, which descends to the most concrete facts, which shows that something has emerged in the physical body that the astral body, the etheric body, the I, has formed. We have natural science that reaches up to the boundaries of spiritual science, and we have spiritual science that has descended to the boundaries of natural science. That is the course of development.

A hundred years ago, looking at two currents – a natural science that did not reach up to spiritual science, and a philosophy that did not reach down to natural science – Schiller said: Oh, you are called to go one way, but for the time being you must still go separate ways so that each one becomes strong enough to help the other. This has been quickly fulfilled. In a way, natural science is strong through its weakness, in that it overcomes itself through its own facts. It will lead upwards. And spiritual science is strong because it can embrace the material. What Schiller recognized and hoped for seems to be coming true. Hopefully there will soon be many people who, with the one spiritual eye, like the woman in the fairy tale told at the beginning, no longer have to take the external beings and hurl them away because they tell them nothing, but there will be people who take every stone in their hands, lead it to a spiritual eye and recognize it as an expression of the spiritual world, because all matter is from the spirit and proclaims it. For materialism there was only matter; nothing was found there and things were thrown away. Spiritual science united with natural science will give man a spiritual aspect in every material thing. We will grow to love everything again because everything is an expression of the spiritual world.

Natural science is at a crossroads. It must either go to one side and be lost, or to the other, where it will stand united with spiritual science as the one world view; so that the two together lead man up to a way of life in which the spirit permeates life, so that in this union - which is brought about by facts themselves - a great goal for the good of humanity is achieved. We see it before us today. Let us try to visualize more clearly what we see before us by cultivating spiritual science. Then we will see that we are not doing it to satisfy mere curiosity, but to free ourselves inwardly from all doubts and to make us strong and vigorous and healthy for life. That will be the fruit of the union of natural science and spiritual science: health and strength and security in life!
