Abstract

Ancient philosophy has been a source of inspiration for contemporary philosophy in recent decades. An outstanding example is the renaissance of hylomorphism in the field of philosophy of biology. For the philosophy of mind, hylomorphism has been little discussed so far. Therefore, ancient models in the philosophy of mind are still of interest. This article argues that Plato’s Phaedo can act as a source for contemporary debates. As a starting point, Simmias’s objections to the immortality of the soul are analyzed. Plato does not simply reject these objections, but introduces conditions for a hylomorphistic understanding of the soul in Socrates’ reply. These conditions are the following: (A) the mind supervenes on the body; (B) this supervenience must allow the strong emergence of the mind; (C) the mind comprises causal powers; (D) teleological explanations are a necessary ingredient of a suitable model for the mind-body problem. With these conditions, Plato already introduces central components that are present in contemporary philosophical debates, but have not yet been unified into a hylomorphistic concept in the philosophy of mind. The present article proposes this unification.
