Abstract

This article applies Russon's principles of reading Plato's dialogues to solve a problem arising from both the dramatic and philosophical aspects of Plato's Republic: persuasive speech seems effective only when its audience is already willing to listen and be convinced. Yet if so, then either persuasive speech is powerless to persuade anybody truly, or it is unclear how it differs from simple manipulation or brainwashing. This article resolves this dilemma by using Russon’s insights about the kind of rationality Plato invites us to assume, namely a “concrete rationality,” and by analyzing the first three interlocutors of Socrates in the Republic: Polemarchus, Cephalus, and, of course, Thrasymachus. This approach enables us to differentiate these three interlocutors, explain Thrasymachus’s persistence in listening to the conversation until the end despite his unwillingness to listen, as well as the therapeutic function of theōria for providing him some momentary relief from his “hatred of speech” (misologia).
