### 5. The Nature of Comets

Good morning, gentlemen! Does anyone have a question?

Questioner: A few lectures ago, the great cosmic world was mentioned; I would like to ask about comets with a large tail. What does that mean?

Dr. Steiner: Well, you see, gentlemen, we have to remember what I have said just recently. I will repeat some of what we said a few lectures ago.

When we look at the human being, we have to say: Two things are necessary for his whole life, namely for his spiritual development. Firstly, that carbon dioxide rises to the head. After all, humans constantly excrete carbon within themselves. Actually, one can say: Man, insofar as he is a solid body, is made of carbon. So humans constantly excrete carbon from themselves. Now, this carbon would eventually become so in us that we would all become black pillars. We would become black pillars if this carbon were to remain. We need it to live, but we have to constantly convert it again so that it becomes something else. This is done by the oxygen. Now, in the end, we exhale the oxygen with the carbon as carbonic acid. There is carbonic acid in our exhaled air. But you need this carbonic acid. It can also be found, for example, in mineral water, and the bubbles inside contain carbonic acid. This carbonic acid, which is not exhaled, constantly rises to the human head, and we need it so that we are not stupid, so that we can think; otherwise marsh gas, which consists of carbon and hydrogen, would rise to the human head. So for thinking we need carbonic acid.

Now, I have already hinted at what we need for our will, for our volition. So let's start with walking, moving our hands, moving our arms – that's actually where this volition begins: we always have to form a compound of carbon and nitrogen and then break it down again. But this cyanide or prussic acid must constantly, so to speak, enter our limbs. It then combines with potassium in the limbs. Potassium cyanide is formed, but this is also immediately broken down again. In order for us to be able to live at all, there must be a constant process of poisoning and detoxification within us. That is the secret of human life: carbonic acid on the one hand, potassium chloride, which is connected to potassium, on the other. With every movement, with every finger, a little cyanic acid is formed, and the thing is then that we dissolve the thing again immediately by moving our fingers. So that must also be there in man.

But everything that must be there in man must also be there in the universe, must somehow be present in the universe. It is now the case that comets have always been examined again. And with comets in particular, I would say, a kind of little story has taken place in the anthroposophical movement. I once gave lectures in Paris and, purely out of inner knowledge, said that there must be some cyanic acid in comets, that cyanic acid is present in comets. Until then, scientists had not yet noticed that cyanic acid is present in comets. But then, shortly afterwards, a comet came along. It was the one you are talking about. And it was precisely on this comet that it was discovered, using the more sophisticated instruments that were available at the time, that the comet material really does contain cyanic acid! So that one can point to this when people always ask: Has anthroposophy predicted anything? Yes, this discovery of cyanic acid in comets, for example, was clearly predicted. It was the same with many other things, but in the case of the comet it was quite obvious. Well, today there is no doubt, even in the natural sciences, that in the atmosphere of a comet, in the comet's air - after all, a comet is actually made of very fine material, it is actually only ether, only air - there is cyanic acid.

Yes, what does that mean, gentlemen? It means that the same thing that we constantly have to produce in our bodies is also present outside in the comet's atmosphere. Now imagine how often I have said here that the egg is formed from the whole universe - so humans, animals and plants are also formed from the whole universe, in that they are formed from the egg. I would like to explain this to you using the example of the human being, so that you can see exactly what these comets actually mean in the whole universe.

Let us start with something historical, which may seem strange to some, but you will see that what you want is best explained by it. Centuries before Christianity was founded, there were ancient people in present-day Greece, the Greeks. The ancient Greeks achieved so much for intellectual life that even today our high school students still have to learn Greek because it is believed that if you learn Greek today, you will become a particularly clever person. Well, the Greeks really did achieve an extraordinary amount for intellectual life. Today, people do not learn Indian or Egyptian, but Greek. By doing so, people want to express that the Greeks have achieved a great deal for intellectual life. The simple fact that we cultivate Greek with our high school students shows this. The Greeks themselves only did Greek with their children, even though they achieved so much for intellectual life.

Now there were two main tribes in Greece that were of particular importance, but which were very different from each other: one was the inhabitants of Sparta, the other the inhabitants of Athens. Sparta and Athens were the two most important cities in Greece. In addition, there were a few others that were also important, but not as important as Sparta and Athens. The inhabitants of these two cities were therefore very different from each other. I will ignore the other differences today, but they were different in that they spoke quite differently. The Spartans always sat quietly together and spoke little. They did not like to talk. But when they did talk, they wanted what they said to have a certain meaning; it should have power over people. But because man cannot always say something meaningful when he babbles, they remained silent when they had nothing significant to say, and always spoke in short sentences. These short sentences were famous throughout the ancient world. People talked about the short sentences of the Spartan people, and those that became famous were often tremendous sayings of wisdom.

It was different with the Athenians. They loved beautiful speech; they loved it when it was spoken beautifully. The Spartans: short, measured, calm in their speech. The Athenians wanted to speak beautifully. They learned rhetoric by speaking beautifully. They did indeed prattle more; not as much as we do today, but they did prattle more than the Spartans.

What was the difference between the Athenian who talked a lot and the Spartan who talked less but meaningfully and powerfully? It was based on education. The art of education is of course little studied today. But what I am saying is based on education. The Spartan boys in particular were educated quite differently from the Athenian boys. The Spartan boys had to do a lot more gymnastics: dance, wrestling, all kinds of gymnastic arts. And oratory, the actual gymnastics of the tongue, was not practiced at all by the Spartans. They let speaking come naturally.

Everything that lies in language is formed through the rest of the human body's movements. You can observe it correctly: if a person has slow, measured movements that are truly gymnastic, then they will also speak properly. In particular, if a person walks with proper steps, then they will also speak properly. Of course, it depends on the child's age. If a person gets gout in old age, it doesn't matter anymore; they have already learned to speak. It depends on the time when one learns to speak. But the Spartans attached great importance to practicing a lot of gymnastics, and they supported this gymnastics by rubbing the children's bodies with oil and smearing them with sand; then they let them do gymnastics. The Athenians also did gymnastics – gymnastics were done throughout Greece – but much less, and they let the older boys do tongue gymnastics, oratory. The Spartans did not do that.

Now, this has a very specific consequence. You see, when those little Spartan boys did their gymnastics with their bodies oiled and rubbed with sand, they had to develop a great deal of inner warmth – develop a great deal of inner warmth. And when the Athenians did their gymnastics, it was something very special for the Athenians. If it had been a day like today and the boys had not wanted to do their gymnastics outdoors with the Spartans, well, that would have been it! The gymnasts, the educators, would have treated those boys properly! When the Athenians had a day like today, so stormy, they gathered their boys more in the interior of the rooms and let them do oratory. But they called them out when the sun shone brightly, when everything sparkled. Then the Athenian boys had to do their gymnastic exercises outside. For the Athenians thought somewhat differently from the Spartans. The Spartans thought: All the movements that boys make must be done from the inner body; it may be stormy and hailing and raging and windy outside, it does not matter. They said to themselves: It must come from within.

The Athenian said differently. He said: We live by the sun, and when the sun wakes us up to move, then we want to move; when the sun is not there, we do not want to move. So said the Athenian, and therefore the Athenians looked at the external solar heat. The Spartans looked at the inner warmth of the sun, the warmth of the sun that man had already processed, and the Athenians looked at the outer sun, which shines beautifully on the skin - the skin is not rubbed with sand, at least not as much as it is by the Spartans, but the skin is supposed to be worked by the sun. That was the difference. And when schoolbooks today speak of the difference between the Athenians and Spartans, the only impression you get is that there must have been something wonderful about why the Spartans were quiet, measured in their speech, and also hardy, while the Athenians practiced the art of oratory, which was then further developed by the Romans. People today cannot practice history and natural science at the same time. History speaks for itself, and science speaks for itself. But if I tell you that the Spartans rubbed their boys with oil and sand and then let them practice their Spartan arts in all weathers, and the Athenians did not rub their boys with so much sand and oil and otherwise practiced their oratory inside the palestra, then you know how this difference between the neighboring Spartans and Athenians was actually brought about by natural facts.

So let us say that when we have the earth (it is drawn) and the sun here: if you look at the sun as it shines and there is the Athenian, then the Athenian emerges; and if you look not so much at the sun as at what the sun has already done in man, and you look at the more inner warmth, then the Spartan emerges from that. You see, there you have history and natural history combined. That's how it is.


Now we can say: When a person ensures that he develops a great deal of warmth within himself, his speech becomes short and measured. Why? Because he turns more to the universe with his whole mind. But if a person allows himself to be illuminated by the sun like the Athenian, then he turns less to the universe with his mind; then he turns more inward with his mind, outward with warmth; the Spartan: inward with warmth, outward with mind. And from reason, the Spartan has learned the language of the universe; it is wise, it has been developed within him. The Athenian has not learned the language of the universe, but only the movement of the universe, because he has abandoned himself to gymnastics in the warmth of the sun.

When we look at what remains of the Spartans today, we say to ourselves: Oh, these Spartans have rendered the wisdom of the world in their short sentences. The Athenians began to express more of the mind that is within man in their beautiful turns of phrase. What the Spartans had in their language has been lost to humanity for the most part; it disappeared in Greece with the Spartans. Man can no longer live with the language of the universe today. But what the Athenians began to do: beautifully winding sentences - it became particularly great in Rome with the art of fine speech. And the Romans at least still spoke beautifully. In the Middle Ages, too, people still learned to speak beautifully. Today, however, people speak terrible sentences. You only have to look at it in detail – well, you could take any other city, but in Vienna, for example, the elections have been going on for weeks: yes, they are not beautifully spoken, but terribly, a whole flood of speeches, but not beautifully! And that is what has gradually become of what was still cultivated by the Athenians, albeit beautifully. It comes from within man. The universe, truly, does not make speeches – but man does! The Spartans did not make speeches; the Spartans expressed in their short sentences how the universe speaks. They looked up at the stars and thought: Man, he runs around in the world and is a busybody. The star moves slowly, so that it does not move slowly now, quickly now, but always evenly. Then the saying arose that has remained for all time: haste with Weile - and so on. The star still reaches its goal! And so the Spartans in particular have learned a great deal from what is out there in space.

And now we can move on to something that I have already noticed in your case: we can move from warmth to light. I would just like to say the following about warmth. Consider that if a person needs to develop a great deal of warmth, then he should become a strong person. And if a person has the opportunity to be in the sun a lot, then he should become a person who talks a lot. Now you only need to take a quick look at geography: go to Italy, where people are more exposed to the sun, and you will see what a chatty people they are! And go to the north, where people are more exposed to the cold: yes, you may despair sometimes – people do not talk because, when you always have to develop inner warmth, it drives away the inner urge to talk. Even here with us it seems almost strange when someone comes from the north; he stands there to speak – yes, he stands there but doesn't speak yet. Not so when an Italian agitator steps onto the rostrum, he speaks even before he gets up there, he is already talking down below. Then it continues, then it just gushes! When a Nordic person, who needs to generate a lot of warmth because there is no external warmth, is supposed to speak: a Nordic person like that, he stands there - you get desperate because he doesn't even start; he wants to say something, but he doesn't even start. It's true: inner warmth drives away the desire to speak, while external warmth fuels the desire to speak. Of course, all this can be transformed by art. The Spartans developed this speaking calm not through art but through their own racial character, even though they were neighbors of the Athenians because they mixed a lot with people coming from the north. Among the Athenians, for example, there were many who came from hot climates and intermarried with the Athenians; this is how they developed their flow of speech. So there we see how even the oratorical person is connected to the sun and warmth. Now let's move on to light.

All we need to do is remember something I have already told you. Think of a mammal. A mammal develops the germ for a new mammal internally. The germ is carried internally by the mother animal; everything happens internally. Take the butterfly, on the other hand. I told you: the butterfly lays the egg, the caterpillar crawls out of the egg, the caterpillar pupates itself into a cocoon, and the sunlight drives the multicolored butterfly out of the cocoon. On the other hand, look at the mammal (it is being drawn), this mammal develops the new animal hidden in its uterus. Here we have two contrasts again, wonderful contrasts. Look at the egg: it is uncovered. When the caterpillar crawls out, the light is already coming. The caterpillar, I told you, goes to the light, spins its cocoon, the shell that it becomes a pupa, after the light, and the light in turn causes the butterfly. And the light does not rest and does not rest, gives the butterfly its colors. The colors are caused by the light; the light treats the butterfly.

Take, on the other hand, the cow, the dog. Yes, the little cub inside the maternal uterus cannot have the external light; it is closed off in darkness from the outside. So it must develop inside, in the darkness.

But nothing that lives can develop in darkness. It is simply nonsense to believe that something can develop in darkness. But what is the story here? I will give you a comparison. One can indeed hope that once the Earth becomes very poor in coal, direct solar heat will be able to be used for heating through some kind of transformation; but today that is just not yet possible, that one uses the heat of the sun directly for heating. Perhaps it will not take much longer before one comes up with how it can be done; but today we use coal, for example. Yes, gentlemen, coal is nothing more than solar heat, only solar heat that flowed to Earth many, many thousands of years ago, was trapped in the wood and stored as coal. When we heat, we bring out the solar heat that accumulated in the earth thousands and thousands of years ago.

Do not think that only coal behaves towards the sun as I have just described! Other beings, too, behave towards the sun as I have just described, and that includes all living beings. If you look at a mammal, you have to say: every little young animal has a mother, who in turn has a mother, and so on. They have always absorbed the warmth of the sun; it is still inside the animal itself, it is inherited. And just as we bring the warmth of the sun out of the coal, so the small child in the maternal womb now takes the sunlight, which is stored there, from within. — Now you have the difference between what arises in the dog or in the cow and what arises in the butterfly. The butterfly goes straight into the outer sunlight with its egg, allowing it to be completely transformed by the outer sunlight until it becomes the colorful butterfly. The dog or the cow are just as colorful on the inside, but you cannot see it. Just as the warmth of the sun is not perceived in coal – it must first be coaxed out – so too, with the higher contemplation of dog and cow, one must first coax out what light is stored up within. There is light stored up within! The butterfly is colorful on the outside; sunlight has worked from the outside. Yes, in the dog or the cow, I would say, invisible light is everywhere inside.

What I have described to you, people today could easily determine with our perfect instruments, prove it in their laboratories, if they wanted to. They should just make a laboratory, completely dark, totally dark, and then they should compare in this laboratory a newly laid egg and a cow or dog germ in its early state, then you would see that the dimming that can occur in the dark room shows this difference that I am describing. And if one were to photograph what one does not see with one's eyes - the eyes are not sensitive enough for that - one would be able to prove that the butterfly egg has the spectrum yellow and the dog and cow egg has the spectrum blue in the photograph. These things, which one can see spiritually - one does not need the external when one can see them spiritually - will still be proved with the most perfect instruments.

Now we can say: the butterfly is formed in the external sunlight, the cow or the dog is formed from the sunlight that is stored internally. Thus we have come to know the difference between warmth, which works externally, which makes a person talkative, the light that works externally, which causes the many colors in the butterfly, and the warmth within, which makes a person silent and measured – the light within a being that gives birth to living young, which must receive the light internally. And now we can move on from there to the subject of our question.

There are also things that a person needs inside, but which he must not develop in excess inside, because otherwise he would die from them. And that includes prussic acid, which is also known as hydrogen cyanide. If a person were to continually produce hydrogen cyanide throughout the day, beyond the little bit that is already there, well, that wouldn't work, that would be too much. A person does produce a little prussic acid in himself, but very little. But he also needs some from outside; he absorbs it with what he inhales. It is not much, but a person does not need more.

Now, gentlemen, this potassium cyanide is not present in ordinary air. If comets did not appear from time to time, this potassium cyanide would not be present in the air. Comets and then these meteors, shooting stars, which, as you know, fly through the air in such great numbers, especially in midsummer, bring down this potassium cyanide. And man actually draws his strength from it. Therefore, people who have become weak in their muscles should be sent into the air, which has not only become fresh from the earth, but has become fresh from the whole universe, which has experienced meteorite influences. And it is the case that people who suffer from what used to be called consumption, for example, who become weak in their muscles and for whom this weakness is particularly pronounced towards spring, are sent in the fall to breathe this air that has been refreshed by the universe. In spring there is nothing that can be done; that is why such people most easily die in spring. You have to take precautions, because you can't really do anything for such people until the fall. When the meteor forces deposit their cyanide with the small amounts of potassium cyanide that come in from the universe during the summer, these people should then, when August ends and fall comes, with their weak limbs, come to areas where summer has deposited its best, namely potassium cyanide. Then their limbs become strong again. So for people you notice this happening to, the next year will be very bad for them, because they become weak, and you should actually take precautions in the spring, when you can't do much with external things. You should say to yourself: When spring comes, I will give such people, depending on how weak they have become, the juice of certain plants, for example the juice of blackthorn. If you store the blackthorn juice – you know the tart, acidic plant – and bring it into the mouth of a person who becomes weak in spring, you can sustain them throughout spring and summer. Why? Well, you see, when you give a person the juice of blackthorn, this blackthorn juice forms all kinds of salts. These go to the head and take the carbonic acid with them. So we tilt the head to help this person through spring and summer. And in the fall we have to take him to an area where he is able to take the other thing, which has to go more to the limbs. Carbonic acid goes to the head; we insert it after the head by introducing blackthorn. If we have been fortunate enough to have brought a person through the summer in this way, we can take him to a suitable area in the fall. He should stay for two or three weeks in such air, which we know has just received meteorical influences. Then it is the case that the person, having been strengthened during the spring and summer, really does regain the strength of his limbs.

Yes, gentlemen, there you have the two effects side by side. There you have the earthly effect, which is actually a lunar effect, the earthly effect in the blackthorn juice, and there you have the cosmic effect in what the comets, and when there is no comet, the shooting stars have left behind – it is the same with them, only small; but there are many – which has an effect from the universe. Just as you basically have nothing earthly in the butterfly with its transformation, but light from the universe, just as you have warmth from the universe, from the sun, in the protected eggs, so you also have human warmth within you, which you must develop inwardly in your substance and which stimulates exactly the opposite of the external warmth.

Thus we can see everywhere how there is an alternation in man, but also how there is an alternation in the whole universe: sometimes things must come from the outside of the universe, sometimes from within the earth or from within man. Now you will say: Yes, certain things are regular; but they cannot alone bring about what they are supposed to bring about. Day and night change regularly; they bring about the one thing that comes from the earth. Now, comets appear more or less irregularly; shooting stars too. And that is also the case. There is no such regularity with shooting stars as with the rest. If an astronomer wants to observe a solar eclipse, he can find the exact time when it begins – that can be calculated –; it belongs to the regular, but does not work from the sun. So he can still go to supper beforehand and still get to the solar eclipse. If he wants to observe the meteoritic swarming of shooting stars at the right time, he has to watch the whole night, otherwise he cannot find them. That is the difference between what comes irregularly from the universe to Earth and what is regular.

Now you can raise an interesting question. You can say: The comets that are connected with the cyan - which is connected with our will in our human being - these comets appear irregularly; one comes soon, then it is long absent. - It always also gives rise to superstition in people; but precisely that which does not always appear makes them superstitious when it comes. In the sunrise and sunset, only the formerly prepared human minds have seen the divine; later, superstitious minds have then dreamed up all sorts of things about comets. You may now ask: Why is it not the case with comets that, just as the sun appears at certain hours of the year in the morning, a comet also appears? Well, if that were the case, if comets could regularly appear and disappear with their tails just as regularly as the sun and moon rise and set, then we humans would have no freedom; then everything else in us would be as regular as sunrise and sunset, moonrise and moonset. And what is connected with this regularity in the universe is also a natural necessity in us. We must eat and drink with a certain regularity, and sleep with a certain regularity. If the comets rose and set with the same regularity as the sun and moon, we could not begin to move arbitrarily, but would have to wait: we would be in a state of rigor; the comet would appear, and we could leave! If it disappeared again, we would fall into a state of rigor again. We would have no freedom. These so-called wandering stars are what give man his freedom from the universe. And so we can say: that which is necessary in man, hunger, thirst in their course, sleep, waking and so on, comes from the regular phenomena; and that which is arbitrary in man, which is freedom, comes from the comet-like phenomena and this gives man the strength for the power that works in his muscles.

In recent times, people have completely forgotten how to look at what is free in a person. People no longer have any sense of freedom. That is why, in more recent times, people have become obsessed with what is only necessity. Now people express their attitudes in their festivals. For example, they have festivals for necessity: Christmas, Easter; but they have dropped the autumn festival, the Michaelmas festival, because it is connected with freedom, with the inner strength of the human being. And so, actually, people study at most the material side of the comets. The other, they say: Yes, you can not know about that. - And on the one hand, you see today that people shy away from freedom; on the other hand, you see that they have no real mind, no reason to study the irregularities in space. If they were not there, then you would have no freedom. So we can say: the Athenians took up what was inside people. That made them talkative. On the one hand, materialism has become terribly talkative. But this also makes it insensitive, dull to everything that can be used to strengthen one's resistance to meteorite influences. That is why Michaelmas is at most a farmers' festival, and the other festivals are something that is related to necessities, although they are no longer as respected as they were in ancient times because people have forgotten the connection with the spiritual world altogether.

In this way, everything becomes transparent. When people understand again how beneficial the influence of the comet is, they will probably remember that they like to celebrate some kind of festival in the fall to have a kind of freedom celebration. That belongs in the fall: a kind of Michaelmas festival, a freedom celebration. People today let this pass because they have no understanding of it at all; they have no understanding of freedom in nature outside, and therefore also no understanding of freedom in man. You see, the honorable Lady Moon and the majestic Lord Sun, they sit on their thrones, they want to have everything measured because they have no right sense for freedom in the universe, in the cosmos. Of course, it must also be. But the comets are the freedom heroes in the universe; they therefore also have within them the substance that is connected with activity in humans, with free activity, with arbitrariness, with the activity of the will. And so we can say: When we look up at the sun, we have in it that which always plays rhythmic games within us, the heart and breathing. If we look at a comet, then we should actually write a poem about freedom every time a comet appears, because it is connected with our freedom! We can say: Man is free because in the universe, freedom also reigns for these enthusiasts in the universe, the comets. And just as the sun mainly owes its nature to the acid character, so the comet owes its nature to the cyanic character.

You see, gentlemen, that's where you come to the nature of comets, and that is an extraordinarily significant connection, as you can see that suddenly there is something in the whole universe that is alive, but that lives in a way that is similar to us humans. So you can also say: the Spartans had more sense for the non-withdrawal from the sun, and that is why they appreciated everything that was connected with the universe - this did not arise from external arbitrariness. And Lykurgos, the lawmaker of Sparta, had iron money made. In the schoolbooks you will find: Lykurgos had iron money made so that the Spartans should remain fine Spartans. That is nonsense. In truth, Lykurgos was instructed by those who still knew these things in Sparta; they told him that comets contain cyanide of iron, and so he had iron minted in Sparta as a symbol of the comets for the money. That was something that arose from wisdom; while other nations were changing over to gold coinage, which expresses that which is more in the sun, the image of the solar life in us.

Thus it is that one sees that in the customs of ancient peoples there is still something more of what they knew of the universe.
