‘These teachings are, therefore, no novelties, no inventions of today, but long since stated, if not stressed; our doctrine here is the explanation of an earlier, and can show the antiquity of these opinions on the testimony of Plato himself.’ This quotation, from Enn. V 1.8, where Plotinus is actually presenting his doctrine of the three hypostases – a metaphysical elaboration never envisaged by Plato – encapsulates the interesting relationship which links this great original mind to the other great original mind whom he wished to claim as his master. There is, of course, nothing strange, in the intellectual world of late antiquity, in this desire to base one's doctrine on some time-honoured authority; what is unusual is the degree of originality of the man who is doing this.

Amsterdam, 1967)Google Scholar; Blumenthal, H., Plotinus' Psychology: His Doctrine of the Embodied Soul, The Hague, 1971CrossRefGoogle Scholar; Emilsson, E., Plotinus on Sense-Perception: A Philosophical Study, Cambridge, 1988CrossRefGoogle Scholar; O'Daly, G.

2. All aspects of Porphyry's Life of Plotinus are very fully discussed in the excellent French volume, Porphyre, La Vie de Plotin I: Travauxpréliminaires, ed. Brisson, Luc et al. , Paris, 1982Google Scholar.
3. What follows essentially corresponds to my introductory essay to the Penguin edition of MacKenna's, Stephen translation of Plotinus' Enneads (Harmonsworth, 1991)Google Scholar. Note that, in what follows, I use capital letters (e.g. the One, Intellect, Soul) to designate ‘hypostases’ or other basic realities of Plotinus' system.
4. A certain overlap and tension ensues between the concept of this second god, who is an active intellect, and Soul, since the rational aspect of Soul is hardly distinguishable from Intellect.

8. Whether or not this is a genuine work of Plato's is irrelevant, since it was universally accepted as genuine by later Platonists.
