I reject the traditional picture of philosophical withdrawal in the Hellenistic Age by showing how both Epicureans and Stoics oppose, in different ways, the Platonic and Aristotelian assumption that contemplative activity is the greatest good for a human being. Chrysippus the Stoic agrees with Plato and Aristotle that the greatest good for a human being is virtuous activity, but he denies that contemplation exercises virtue. Epicurus more thoroughly rejects the assumption that the greatest good for a human being is virtuous activity. He maintains that the greatest good for a human being is the tranquility that virtuous activity always and contemplative activity sometimes brings about.

Plato's Republic centers on a simple question: is it always better to be just than unjust? The puzzles in Book One prepare for this question, and Glaucon and Adeimantus make it explicit at the beginning of Book Two. To answer the question, Socrates takes a long way around, sketching an account of a good city on the grounds that a good city would be just and that defining justice as a virtue of a city would help to define justice as a virtue of a human being. Socrates is finally close to answering the question after he characterizes justice as a personal virtue at the end of Book Four, but he is interrupted and challenged to defend some of the more controversial features of the good city he has sketched. In Books Five through Seven, he addresses this challenge, arguing (in effect) that the just city and the just human being as he has sketched them are in fact good and are in principle possible. After this long digression, Socrates in Books Eight and Nine finally delivers three "proofs" that it is always better to be just than unjust. Then, because Socrates wants not only to show that it is always better to be just but also to convince Glaucon and Adeimantus of this point, and because Socrates' proofs are opposed by the teachings of poets, he bolsters his case in Book Ten by indicting the poets' claims to represent the truth and by offering a new myth that is consonant with his proofs.

I defend the Stoicizing view that Socrates in the Euthydemus really means what he says when he says that wisdom is the only good for a human being. By taking the deniers' case seriously and extending my Stoicizing interpretation to the Euthydemus as a whole, I aim to show how the dialogue calls into question three prominent assumptions that the deniers make, assumptions that reach far beyond the Euthydemus and that are made by more than just the deniers. First, the deniers misread Socrates' argument that wisdom is the only good because they misunderstand what makes a protreptic argument successful. I show that the Euthydemus both raises a difficult question about reasons one might have for radical change in view and suggests a sophisticated answer. Second, the deniers' philosophical doubts about the Stoic claim rest on a mistaken interpretation of Socrates' ethical theory. I show that the Euthydemus offers a more plausible picture of Socratic eudaimonism that accommodates the Stoic claim. Third, when the deniers rely on evidence outside the Euthydemus to cast doubt on the Stoicizing reading, they rely on a dubious methodological assumption about how to read Plato's Socratic dialogues. I argue that the Euthydemus calls for a different approach
