Lecture III

Now, you will perhaps recall how, in my book The Case for Anthroposophy,[^5] I tried to explain the human organization in a way corresponding to modern thinking. I divided the human organization—meaning the physical one—into the nerve-sense system, the rhythmic system, and the metabolic-limb system. I need not point out to you that I did not divide man into separate members placed side by side in space, although certain academic persons have accused[^6] me of such a caricature. I made it clear that these three systems interpenetrate each other. The nerve-sense system is called the “head system” because it is centered mainly in the head, but it spreads out into the whole body. The breathing and blood rhythms of the chest system naturally extend into the head organization, and so on. The division is functional, not local. An inward grasp of this threefold membering will give you true insight into the human being.
