This paper has been prompted by the conviction that a number of ethical and political doctrines in Plato remain obscure and somewhat unintelligible unless related to the contemplative experience of the Platonic philosopher.1 I shall concentrate here on one such doctrine, the distinction between philosophic and popular virtue, especially as it appears in the Phaedo and the Gorgias. But in order first to clarify our conception of the relationship between contemplation and virtue, I shall examine the fourteenth-century English classic, The Cloud of Unknowing, which is mainly concerned with the practice of contemplation and only remotely connected with Plato.2 One finds in The Cloud a perceptive account of the contemplative's acquisition of ‘perfect’ virtue which enables us to see the distinction between philosophic and popular virtue in Plato in a fresh light. After discussing the important passage in the Phaedo (69A–C) where the distinction is drawn, I shall criticise the account of virtue in Plato given by D. Z. Phillips and H. O. Mounce in Moral Practices where the contemplative context is minimised by their endeavour to see morality wholly in terms of conventions (albeit, for Plato, ‘non-conventional’ conventions).3 In this section, the argument between Socrates and Polus in the Gorgias will be discussed in light of the way Phillips and Mounce distinguish their respective ethical positions. The object of the paper is not only to point to the significance of contemplation in Plato's ethics which has been overlooked by many modern philosophers, but also to note the way our understanding of the dialogue form in Plato depends on the unique perspective of the contemplative philosopher.
