The Rhetoric of Plato's Republic Democracy and the Philosophical Problem of Persuasion

As Kastely shows, the Republic begins with two interrelated crises: one rhetorical, one philosophical. In the first, democracy is defended by a discourse of justice, but no one can take this discourse seriously because no one can see-in a world where the powerful dominate the weak-how justice is a value in itself. That value must be found philosophically, but philosophy, as Plato and Socrates understand it, can reach only the very few. In order to reach its larger political audience, it must become rhetoric; it must become a persuasive part of the larger culture-which, at that time, meant epic poetry. Tracing how Plato and Socrates formulate this transformation in the Republic, Kastely isolates a crucial theory of persuasion that is central to how we talk together about justice and organize ourselves according to democratic principles.
