The Matter at Hand: Prime Matter as an Unqualified Body in a Post-Hellenistic Pseudepigraphic Text

Abstract The treatise On the Nature of the Universe , attributed to the Pythagorean Ocellus, has frequently been the subject of scholarly attention due to its engagement with Aristotle’s theory of elemental transformation or its role in the late Hellenistic debate on the eternity of the universe. In this paper, I argue that its author endorses a peculiar conception of matter: prime matter is an unqualified body, only potentially perceptible. Ps.-Ocellus draws this doctrine from Stoicism but reworks it for his purposes outside the framework of Stoic corporealism. The author presents it as an antecedent to both Plato’s receptacle and Aristotle’s prime matter. As it turns out, the doctrine was meant to address some of the challenges posed by an incorporeal material principle.
