10. The Supernatural Human Being III
This is based on the fact — and today I want to go further than I thought necessary to go in that book — that human beings do not merely have in their organization what is progressive evolution, which natural science considers solely and exclusively. In recent months, I have argued that such a view considers the whole matter one-sidedly and that it has introduced all the false perspectives into scientific thinking that are found there today. One must also look at a retrograde development, a devolution. The human organism is truly a wonderful structure; it is not only in a life that can be described with the concepts used by natural science today that life proceeds in a certain ascending development; rather, human nature itself undergoes a retrograde development, and the strongest retrograde development in this human organization is everything connected with the sense organs, with the head.
