Abstract

This chapter focuses on the human body and how it falls out of Spinoza's physical picture in a natural way that it is a modification of something more fundamental. Spinoza's further view that the human mind is Substance's understanding of the universe when restricted to the human body implies that the mind, too, is a modification of something more basic, namely, Substance's thought. The appearance of a human body in Spinoza's plenum is merely the emergence of a new pattern of motion and rest within Extension. The Aristotelian thesis that the real definition of a human being is rational animal may sound to us too “logical” or “formal” to count as a piece of natural philosophy, a piece of natural science. Spinoza's view that finite things depend on the invariant structure of some more basic order brings his natural philosophy much closer to ours than to Aristotelian natural philosophy.
