What Has Aristotelian Dialectic to Offer a Neoplatonist? A Possible Sample of Iamblichus at Simplicius on the Categories 12,10-13,12

Abstract

Abstract Simplicius in Cat. 12,10-13,12 presents an interesting justification for the study of Aristotle’s Categories, based in Neoplatonic psychology and metaphysics. I suggest that this passage could be regarded as a testimonium to Iamblichus’ reasons for endorsing Porphyry’s selection of the Categories as an introductory text of Platonic philosophy. These Iamblichean arguments, richly grounded in Neoplatonic metaphysics and psychology, may have exercised an influence comparable to Porphyry’s.
