Abstract

This paper deals with an aspect of John Philoponus’ psychology, a 6th century Byzantine writer, which marks the early phase of his philosophical career. It is the ochēma/pneûma theory, which in Philoponus’ case represents an unusual fusion of Aristotelian, Platonic, and Stoic philosophy with Galenic physiology and anatomy. In this paper, we examine how this Christian Neoplatonist attempts to assimilate elements of two ancient traditions – philosophical and medical – into a peculiar psychological concept.
