Abstract

Simplicius claims in his Commentary on Aristotle’s Categories that quality is prior to the qualified according to nature. However, in an interesting passage in the same commentary, Simplicius describes the relation between quality and qualified in such a way that it strongly suggests an ontological simultaneity. The aim of this paper is to clarify Simplicius’ notion of natural priority and to investigate the extent to which the assumption of a natural priority of the quality over the qualified is compatible with the assumption of a co-existence of quality and qualified.
