Knowledge and hedonism in Plato'sProtagoras

Abstract

The argument in theProtagoraswhich starts with an analysis of giving in to pleasure in terms of ignorance, and leads into a demonstration that courage is knowledge, is certainly one of the most brilliant in Plato and equally certainly one of the trickiest. My discussion deals mainly with three problems: (I) Precisely what absurdity is detected in the popular account of moral weakness, and where is it located in the text? On the basis of largely formal considerations I believe that the absurdity is a much less subtle affair than has been thought, and that it is located at 355c-d. (II) What is the connection between knowledge and belief in 358b-d, and how do these two concepts figure in the arguments which precede and follow this passage? Here I want to comment on differences between theProtagorasand other Socratic arguments. (III) How good is the argument at 356–357e which analyses moral weakness as ignorance? There are several problems here, including a fundamental puzzle of the dialogue, namely that, apparently, Plato uses a non-Socratic hedonism to establish the Socratic thesis that virtue is knowledge. Here I agree with those critics who see irony at the expense of the sophists—sophistic teaching is shown to be grounded in hedonism—but in addition I suggest that Plato also offers an oblique criticism of hedonism itself in the course of which basic points of real substance are made. This interpretation fits in with various other features of the dialogue, including the curious fact that, though the main argument proceeds on a thorough-going hedonistic basis, Socrates is subtly but distinctly not committed to that basis. Hence the unity of the dialogue is supported, and as well an attitude to hedonism is given which is more consistent with that of other dialogues, while we are able to see the Socratic paradox in its regular role as a tool of ethical exploration.
