 The hierarchy of hypostases the One, Intellect and Soul has already been sketched. Given the available texts with certainty attributable to Porphyry, in particular the Sententiae, there would be no strong reason for supposing Porphyry’s metaphysics to differ significantly from that of Plotinus, though he does not always follow his vocabulary. Furthermore, Porphyry has a different and more Aristotelian conception of the branches of philosophy than Plotinus, who claims dialectic as the supreme philosophical method (Hadot 1966; Strange 2007; cf. Plotinus, Ennead I. 3). This different conception is shown, for instance, in his arrangement of Plotinus’ treatises which follows a pattern of ethics, physics, psychology, and ontology.
