V. Connections Between Organic Processes and the Mental Life of Man

At all events, we gain a more exact knowledge of the configuration of the soul. To begin with, we learn to give up the preconceived idea that our psychic constitution is merely an adjunct of the sensory and nervous system. Only the world of representations is correlated to the nervous system, the world of feeling not at all. The world of feeling is connected directly with the rhythmic organization; and the world of will is adjusted to the metabolic and limb system. If I will something, a corresponding activity is induced in my metabolic and limb system, the nervous system being there only in order that concepts may be formed in regard to what takes place in the will. There are no nerves of will, as I have often stated; the division of nerves into sensory nerves and nerves of will is absurd. The nerves are all of one kind, and the so-called nerves of will exist for no other purpose than the inner observation of the processes of will. They too are sensory nerves.
