### III. The Human Eye — Albinism

Gentlemen, the question that has been asked is:

Is the iris in the eye the mirror of the soul in a healthy and diseased state?

I think the second question can be added, they are probably meant together:

What causes albinism or leukopathy in black people?

If we want to answer this question, we must first take a closer look at the workings of the human eye. The question relates to the fact that certain people can tell whether a person's entire body is healthy or sick by looking at the color of the iris, the colored ring-shaped body in the eye that surrounds the black of the so-called pupil. Not only, as you know, is a person's iris colored blue or black or brown or gray or even greenish brown, but the iris also has lines drawn in one way or another, which are created by fine vessels. So that, just as the general facial expression of one person is different from that of another, the finer structure of this iris or rainbow skin is quite different in different people, and much more different from each other than the actual physiognomy of people is different from each other.

Now we have to go into the structure of the eye a little if we want to talk about such a thing. This is connected with the other question you have asked. Namely, that especially in Negroes, but also otherwise, in non-black people, an abnormal, not quite ordinary skin coloration occurs, which is connected with the special coloration of the iris. This is connected in a certain way. Now this skin color is particularly noticeable in naturally black people, because they are just black, and then they have all kinds of white spots, and are then mottled like a tiger. They are very rarely completely pale and completely white; this occurs very rarely among Negroes, extremely rarely. But such so-called albinos also occur in other races that are not completely black. But this albinism also occurs in white people, in the so-called cockroaches – that's what they're called – they have a very pale skin color, almost milk-white skin color. Then they usually have a light reddish iris, and the pupil, which is otherwise black in humans, is then dark red. I once saw a female cockroach like this who even exhibited herself in all kinds of sideshows and let herself be seen. She had milky-white skin, a red iris or rainbow-shaped pupil, dark red pupils instead of black eye stars, and would then say in an extremely weak voice: “I am all white, have red eyes and see very weakly.” That was true, she saw very weakly.

If we want to get into this matter, we must, above all, study the structure of the eye itself. Over time, I have told you many things about the eye. Therefore, today you will perhaps understand what I have to say. You see, the eye is located inside the very firm bony body of the head. The bone structure of the head bulges inside, and in this bone cavity, which is open towards the brain at the back (see drawing), the eye sits inside. The eye is now first limited from the outside by a hard skin, which is opaque here. The so-called eyeball is limited by the cornea. This skin becomes transparent towards the front, here, where it bulges out a little. Otherwise, one could not approach the light with the inside of the eye if this outer cornea were not transparent. It is called the cornea because it is horny. Inwards from this is a skin, which consists of fine veins. The blood network of the body extends into the eye and also sends very small, fine veins into the eye. So here we have the hard cornea, which becomes transparent towards the front, and then the so-called choroid, which is adjacent to it. The third skin inside is formed from nerves; this is the so-called retina. So I still have to draw a third membrane, the retina. And the retina goes backwards into the brain, as does the choroid, of course. And this is called the optic nerve because it is a nerve substance, it goes to the eye. You know that people say: you feel through the nerves. — So with the optic nerve you see.

Now, the strange thing is that everyone has to admit that, as people say, you can see with the optic nerve everywhere here, except precisely where it enters; there it is blind, you see nothing there! So if someone looks just enough to somehow see out there, or if the nerves around it are diseased and only the spot where the optic nerve enters is healthy, then you still see nothing where the optic nerve enters. Now people say: with the optic nerve you see, it is there for that, that you see. Have you now heard the following? Just imagine: there is a group of workers, let us say thirty workers. Twenty-five of them have to work very hard; they are standing everywhere. And there is a group of five – they won't do it, but I'll assume they do it – these five are allowed to laze around while the others work hard. So we can say: there are the 25 hard-working laborers, and there are five who laze around all the time, sitting on padded chairs and lazing around. If someone were to tell you that the work is being done just as well by the five idlers – or perhaps he can't say that because he doesn't see it, but the work is accomplished by idling – you won't believe it, will you? That is nonsense. But now science teaches us that the optic nerve sees. But precisely at the point where it is most, it sees nothing! It is just as if you were to say: the work is done by what the five loafers are doing. You see, one knows such things—that is precisely the strange thing—one knows such things, but one nevertheless continues to assert quite ordinary nonsense. Isn't it, from the fact that here is the so-called blind spot—that's what it's called—and that you see nothing at all at the point where the optic nerve attaches the most, it is quite clear from this that the optic nerve cannot be what you see with.

The thing is this: there is something in the human body that is very similar to this thing in the optic nerve; namely, your two arms and hands. Imagine picking up a chair. You strain your arms all the way down to your hands. But what connects them stays up there, doesn't it. It's the same with the optic nerve. They are aiming at something that is affected by light, and in the middle it is as it is between the two arm approaches here. But it is not the optic nerve that is affected - because if it were the optic nerve, it would have to see the most of all - but what is affected is something of the very invisible that I have described to you. That is precisely the I, the ego organization. It is not the physical body, not the etheric body, it is not even the astral body; it is the I. And so I have to draw something else in there besides what is already there: there is the invisible I that is spreading out. Only it is not as if there were two such arms, but rather as if the arms were closing and becoming a sphere. We already begin to make a sphere with our hands when we touch something. So there is the supersensible I; it is reaching out there. And what is the nerve for? Yes, gentlemen, the nerve is for this purpose - because it is the work of the invisible human being - that something is secreted. Substance is secreted everywhere, and it remains there everywhere. With the supersensible self, one sees. But the nerve is there to secrete something.

Think of the nonsense that science says, just as if one were to examine the large intestine and what is inside it, and then immediately say, from what is now being excreted from the large intestine, that this is how humans nourish themselves! Just as what is excreted is inside the large intestine, so the nerve substance is excreted here. And this (the blind spot) is then the place where it is excreted the most. What is not needed in the eye is excreted into the brain, then goes further and is excreted at all. You see, this is something that you can easily understand, but about which the most fantastic stories are told to you today. It's just that people don't realize what it means when it is said that the nerve substance is seen or felt or something is perceived. That would be just as if one were nourishing oneself with the contents of the rectum. So you see that this business of the blind spot has no significance for vision, because the optic nerve does not see around it either, only here, where the blind spot is, is where the most secretion occurs. And just as nutrition ends in the rectum, where it is only for excretion, so here too vision ends, because that is where most is excreted, and because it makes no sense for vision to be in the middle.

Imagine you have a stick lying there and want to pick it up with your head! You can't. You have to pick it up with your arm, with your hand, with what is attached at the side. You can't see with your nerve either. You have to see with what is attached.

Now, gentlemen, everything that is there (pointing to the drawing) ends here in a kind of muscle. This muscle carries the lens. This is a completely transparent body. Why transparent? So that you can get to the light. And behind this body here is a thick liquid. In front of it is an even thicker liquid, and in this thicker liquid at the front floats the iris or rainbow skin, which is located here near the veins. It really floats in the liquid and leaves a hole open for the light. This hole appears black when you look into it, because you look through the entire eye to the background, which is black.

This iris is fairly transparent at the front, but at the back it is black. This black skin at the back is quite thin in some people. Because if it is thin, when you look through the transparent part into the black, certain people have blue eyes. And in those with thicker skin here, where you look at the thick back skin at the iris, they have black eyes or dark eyes. We will talk about brown eyes in a moment.

Now, gentlemen, we need to educate ourselves about what it is that causes the skin here, which actually determines the blue or brown or black, to be thicker or thinner in some people. I have already told you: what is called the I, the noblest, supersensible part of the human being, goes into the eye. The I goes into it. The I is more or less strong in different people. Now suppose a person has a very strong ego. You see, such a person is capable of completely dissolving the iron that is in the blood and that he also gets into the eye through this choroid. So someone with a very strong ego completely dissolves the iron, and the result of this is that little iron enters this skin, which is at the very outermost edge of the body, because it is completely dissolved. So little iron enters, and the result of this is that this skin becomes thin. Because it becomes thin, you get blue eyes. Now imagine that a person has a weak ego; then he does not dissolve the iron as much, and the result of this will be that a lot of undissolved iron gets into this skin. The skin becomes thicker because of this undissolved iron and the person gets dark, black eyes. So it depends on the ego whether the person has black or blue eyes.

Now, gentlemen, there is also another substance in the blood: sulfur. And even if the ego can process the iron, it is sometimes still unable to process the sulfur. If the ego lets the sulfur into the skin without processing it, then a yellowish-brown color develops in the iris, and that is how brown eyes come about. And if a lot of sulfur gets into the eyes, then a reddish iris develops. Because of the sulfur shimmering behind it, even the pupil does not turn black. You do not see the black, but the emitted, sprayed sulfur itself makes the pupil dark red. This is the case with cockroaches and humans who otherwise cannot supply their skin with the right color. So you can say: there are people who can inject sulfur into their eyes. The ego can inject it, and this is how the iris gets its special color.

But what goes into the eye in the way of sulfur or iron goes into the whole body, because it comes from the blood. There are only small blood vessels here in the eye. So if someone injects sulfur into the eye, he injects sulfur into his entire skin everywhere. And the consequence of injecting sulfur into his entire skin everywhere is that he does not have his natural skin color at the points where the sulfur has been injected; because the natural skin color comes from the processing of iron. So when a person processes their iron only slightly, but instead spews sulfur, then they get such mottled spots in their skin, and at the same time you can see it in the color of their eyes.

So you see: when you look at this invisible human being that is in every human being, you can understand the human being right down to the material level, right down to the substance. Anthroposophy is not so stupid that it does not understand the material. Materialism does not understand the material. Read somewhere about albinism, what can you read? The one of you who asked me the question will probably have read somewhere: the cause of albinism is unknown! — Materialism always comes to this strange conclusion: the cause is unknown! — because it does not trouble itself at all with those cases where the causes can be found. Of course it is easy to say: There is a red pupil. Yes, but one must know what is actually working inside and what history injects, because the red coloration and the pale coloration of the body comes from sulfur.

Now you can understand what real science is. Imagine you come to a place on earth where something has been worked on; someone looks at it and says: The work is already there, the cause is unknown. He does not care what happened before; that is why he states: the cause is unknown. He does not care that, for example, thirty people have been working there for many days. That is how science does it when it says: the cause of the red coloration of the pupil and the pale coloration of the skin is unknown. — But the cause lies precisely in the I that works in the matter, in the substance.

But from this you can also see that the iris really does contain a true reflection of how the whole body works with iron and sulfur. But take such an albino, such a cockroach; that is actually a kind of disease. There is too much sulfuric work in the body, but the body gets used to it, and it is organized. But now it can happen that this enters the eyes to a much lesser extent. You see, apart from the cockroaches I told you about, apart from the lady who exhibited herself in the show, I have seen many cockroaches. You can always tell that there is something very special about such cockroaches. You can say: There is a cockroach, an albino like this, and it has this peculiar reddish coloration of the iris, pale red, has the dark red coloration of the pupil, has the pale body. If you examine it further, you get from the nature of its body the view that in its case the connection between heart and kidney is particularly weak. He is not only weak in the eyes, he is weak in the connection between heart and kidneys. The kidneys of such a person are supplied with blood with great difficulty, so they work very hard. If he were to deposit the sulfur that he carries throughout his body in his kidneys, he would die as a child. Therefore, he releases the sulfur through the surface of the body – the skin turns white, the eyes turn red – so that the kidneys can work gently. Such albinos have kidneys that work very gently, for example. This can also occur in other people. But if, in people who are not cockroaches (most of them are not cockroaches), some kind of defect occurs in the kidneys, then doesn't it have to show up in the iris as well? What the sulfur and iron do together there is also expressed here. From the nature of the human iris, one can therefore conclude whether there is any damage in the human body. Therefore, if there is a spot here or there in the fine appearance of the iris, which is not actually normal, one can see: there is damage in the body. But, gentlemen, you have to bear this in mind: the human body is a unified whole, and what you see in the iris you would also see, if you were clever enough, if you cut out a small piece of skin and took it out – something would also appear in the skin that would not be normal – or even if you cut the nail of your big toe. There is also a very fine structure that could show if the liver, kidneys or lungs were not working properly, although it is a little different again. So if someone were particularly clever and, instead of examining the iris, were to examine the cut fingernails, for example – it would be much more difficult because it is not as pronounced – they would also be able to recognize the healthy or diseased condition there. It is only noticeable in the eye because the eye is an especially delicate structure, and the delicate is easy to grasp. It is most pronounced in the eye. But you can see that things are most pronounced on the surface of the body. For example, I have rarely seen someone put something on their shoulders when they want to feel a particularly fine material or something like that. If it were the case that it would be more advantageous, we would do something about it, so that when we have to feel something fine, we could free ourselves up there on the shoulder and feel it. But that doesn't help us. We feel it with the fingertips. And at the fingertips we are particularly sensitive to feeling things. There you have the same thing again. If the nervous system were what actually makes up feeling, then we should feel the most where we are close to the brain. But we don't feel the most close to the brain; instead, we feel the most where we are furthest from the brain, in the outermost fingertips, because the I sits most on the surface of the body. What a person is in their inner self can best be recognized on the outermost surface. Therefore, because the eyes are closest to the surface, they can also recognize the most, because the eyes are delicate and far away from the brain.

You may say: The eyes are in the skull and close to the brain. But there are quite a few bones in the way, and where the eye is connected to the brain, where there is no bone, nothing can be seen. So at the fingertips, it is due to the vastness of space that they are particularly sensitive; in the case of the eyes, it is because they are most protected from the brain.

There is something else that is strange. When any lower animal develops its brain, it develops the brain in such a way that the brain leaves the cavity free for the eye, and the eye does not grow out of the brain in that way, but rather it starts from the side and grows into it (it is drawn). The eye grows from the outside, not from the brain; the eye grows into the brain. So it is formed from the outside.

From all this you can see that what is formed on the surface, whether in the skin or in the eye, is connected with the way in which a person is actually most in touch with the outside world. In a person who is always in bed, who cannot use his will for his body, one cannot say that he is developing his ego strongly. In a person who is very mobile, one can say that he expresses his ego strongly. And that which otherwise brings us into contact with the outside world, that is precisely in smelling, seeing and so on, these are the senses. And the eye is just the most delicate sense that brings us into contact with the outside world. So you can say: because the I is particularly strong in these fine veins – there are terribly fine veins in this iris – you can see a lot from this, how the whole I works inwards, whether a person is healthy or sick.

That is the original truth and knowledge that can be gained about this matter. But the fact that I have just described to you is also one of the most difficult, because one must be very thoroughly informed about what such a small irregularity in the iris means if one wants to draw conclusions about a healthy or sick person. I will give you an example. You see, it may be, for example, that in some irises there are dots, dark dots, here or there. These dark dots naturally mean that the person has something that is not there otherwise, if these dark dots are not in the iris. But suppose the person in whom these dark dots appear were a terribly stupid fellow. Then he will have some kind of illness that these dark spots indicate. But in the case of the person with these dark spots, it may also be that in his youth he was overstrained with some kind of learning, had to learn beyond his physical strength. Then, as a result of having used certain organs too much in his youth, he may have developed a certain weaker activity in the eyes, and then these small iron deposits, these very fine iron deposits, can occur as a result of overexertion in childhood. So they can occur as a result of an illness in later life, but they can also occur as a result of overexertion in childhood. Most people think: if I see black spots in the iris, then there must be this or that in the body. But it depends on knowing not only the present life of the person concerned, but especially if you want to recognize something like this in terms of the causes of the disease, you have to go through the whole life of the person with him; you have to let him remember what he has already done here or there in childhood. Thus, what one sees in the iris can point to many things. And to draw conclusions from something like this to something in particular is one of the most complicated forms of knowledge.

That is why it is so outrageous that all kinds of little books are being written today; the things that are written there are usually very short and are called: On Eye Diagnosis. There you get a fifty-page instruction on how to examine the iris. Like this, right? There is the iris classification, there is the pupil, drawn quite schematically, then the disease is indicated; spleen disease is then indicated; lung disease, syphilis and so on. Now the eye diagnostician in question, who is familiar with what is recorded in this way, when he looks at the iris with a moderate magnifying glass, need only refer to his little book; and when he notices what is written where lung disease is written, he states: lung disease! And that is how numerous eye diagnosticians do it today after a study of an hour. They then leave the rest to the little book they have; they just make the diagnosis. Yes, gentlemen, but that is outrageous. Because what is most difficult is to be learned in the easiest way. This does not lead to the acquisition of something valuable, but on the contrary, it damages the whole medical system. And one must distinguish whether someone seriously wants to achieve something in the medical field, or whether someone just wants to make money.

Of course, people are upset about science today; and rightly so, because, according to the example of the optic nerve that I told you about, science actually does not pay attention to what a person really is, but most appreciates the filth of a person, the filth in the eye, for example, which is the optic nerve. Of course, people don't know that, but they feel it and become disgusted by science. This outrage can be understood. But what the eye diagnostician usually does is not better than science, but usually much worse. Science, unsuspecting because of materialism, considers dirt to be the noblest components of the human being. Of course, the dirt is also very necessary, because if it were to remain in the body, it would kill the body very soon; so it is necessary. But science thinks that dirt is the most valuable thing about a person! But that means it is on the path of good and does not just want to make money. It is just blinded. It just has a very large blind spot in its knowledge; but with all that, one must acknowledge the good will. But with these little eye diagnostic devices, one can no longer speak of good will, only of the desire to make money. That is why you always have to ask yourself about all these things: a good truth can underlie any endeavor, but it is precisely the best truths, gentlemen, that are most often misused by the world. You see, it is truly wonderful that in this little iris the healthy and the sick person are both completely reflected. But on the other hand, because the healthy and the sick person are both completely reflected, the iris is also most difficult to recognize in its entirety, and it must be said that anyone who practices eye diagnosis without recognizing the whole person, without really knowing something about the whole person, is practicing nonsense.

And what does it mean to recognize the whole person? You see, we have learned that the human being consists of a physical body, an etheric body, an astral body and the I. So not only do we need to know something about the physical person, but, especially if we are doing eye diagnosis, we also need to know something about the spiritual person. The usual anatomy, which only deals with the corpse, can, under certain circumstances, suffice with what it offers; it can actually offer relatively good things. Even if it does not know that the eye nerve is the dirt of the eye, at least it finds the eye nerve. But the eye diagnostician usually has no idea how the nerve runs, but has his little book of fifty pages and the classification of the iris and diagnoses away, without examining the person. Now, of course, he needs some other little book, again of fifty pages. There is the rubric “lung disease” and the remedy for it. But lung disease is something that can come from many causes. Knowing that the lungs are affected is not enough. The lungs can be affected by digestion. You have to know where it comes from. Many people suffer from lung disease. For many, the lung disease has a wide variety of causes. This is precisely where you have to be extremely careful, because where the most beautiful things are present, there is the most nonsense. How much have I told you in these lessons about the fact that man does not depend only on the earth, but on the whole starry sky. But that is precisely what requires the most complicated insight. You must not do any nonsense with it. After all, the various astrologers in the world today are doing a great deal of fraud and nonsense. It is similar with eye diagnostics as with astrology. There is also something very noble and magnificent underlying astrology; but for those who practice astrology today, there is nothing very noble underlying it. For them, speculation about the wallets of their fellow human beings is usually the underlying basis.

And so you can understand the connection, gentlemen: on the one hand, there are the phenomena that change the entire surface of the human being externally. The person gets pale spots where the skin is otherwise darker; his eyes change color, he is an albino. A certain activity is driven to the surface, diverted from the internal organs. But if the person is not a cockroach, not an albino, then the same things, the outer appearance of the eye, are present in the iris; but the finer structure, the finer arrangement then points to the inside. An albino is not a completely sick person just because he is an albino, but he is only afflicted with a predisposition to disease because he has it from an early age and his physical makeup becomes accustomed to it later.

You see, it is not at all good to call the albino a leukopath. This already indicates, because leukocytes, for example, are certain bodies in the blood, that the blood of such people is different. We do not know the cause. But if the blood becomes paler on the surface, then the general pallor does not occur, but the skin becomes paler on the surface. That is the difference between the disease of anemia, where the blood simply becomes paler on the inside, and leukopathy or albinism, where the blood is pushed more to the surface. So it is the case that in the case of people with anemia, an activity in the interior is not in order. The ego is more active on the surface, the astral body more in the interior. Therefore, all the bodies with which one sees and hears are more pushed to the surface. You need them for the ego. You need your liver in the inner being. And if you felt everything as strongly as your liver does, then you would constantly observe only your inner being and say: Aha, now I have just received a little cabbage soup in my stomach, the stomach walls are beginning to absorb it. It is like a radiance, very interesting. Now it goes through the pylorus into the small intestine; now it goes into the villi that are on the intestinal walls. You would observe all this, and all this, that would be very interesting; but you would not have time to observe the outside world! It is very interesting and there is plenty to observe and in some things much more beautiful than the outside world, but the human being is just quite distracted by it. So in general, what is inside does not come to consciousness; what lies on the surface comes to consciousness. So if someone does not process the iron properly in his inner being, where the astral person is more active, he will become an anemic person. If he does not process the iron properly on the outside, but dissolves it as I have described to you, then he will become an albino - which is very rare - or he will get leukopathy.

So you see, the question I was asked is related to this: albinism comes from an irregular processing of sulfur or iron by the ego. Anemia comes from an irregular processing of iron by your astral body and has more of an effect on the inside of the blood. Thus, if one only understands the human being correctly in what is going on inside him, one can also see which supersensible part of the human being is actually involved. He who properly understands the physical human being also understands the superphysical, the supersensible human being. But with materialism it is just the opposite: he does not understand the supersensible human being at all, and therefore he does not understand the physical human being either.

I will let you know whether I will be back next Wednesday. Perhaps someone will have another question by the next lesson, so that a similar discussion can take place as a result of this question.
