III. The Human Eye — Albinism

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.
