Abstract

This material object, my body, is no different in the constitution of its matter from the rest of the physical universe. And my knowledge of it uniquely from inside has led us to the conclusion that what in its outer nature is matter in motion is, in its inner nature, activity of will. This puts into my hand the key to understanding the inner nature of the world: the whole empirical world, what we have called the phenomenal, appears to be matter in motion, but in its hidden inner nature it is will. The noumenal will, however, is unknowable, not self‐experiencing but a blind, purposeless force, such as moves the galaxies. In keeping with this, in human beings it is the Unconscious.
