Aristotle Categories

Dexippus, a pupil or follower of lamblichus, preserves a crucial moment in the Neoplatonist interpretation of Aristotle. Aristotle's" Categories" has been attacked by Plotinus, but Porphyry's defence proved decisive, so that the "Categories" was acceptable as compatible with Platonism and an essential introduction to the Neoplatonist curriculum.
Porphyry's main commentary on the "Categories," however, containing the vital defence, is lost, as is that of his pupil lamblichus. The ideas of these two principal Neoplatonists can be reconstructed, in part, from Dexippus.
