III. The Human Eye — Albinism

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.
