Schopenhauer and the problem of the movement: will and causality. An essay about the chapter “Physical Astronomy” of “On the will in nature”

Abstract

The text “Physical Astronomy” presents the central idea of Schopenhauer philosophy, expressed in movement terms. Dealing with this problem of movement at its origin, we can observe important resemblances between philosophers like Thales of Miletus and our author. All in all, Schopenhauer suggests that there are not two origins of the movement, one internal and own, which belongs to the man, and other external and causal, which acts in the rest of the things, but an only source of movement that joins the both properties and which appears equally in every being. This idea breaks down the barrier between human and natural things, and according to the first philosophers we can say that “all is one”.
