Plato's Critique of Impure Reason: On Goodness and Truth in the Republic

Plato's Critique of Impure Reason offers a dramatic interpretation of the Republic, at the center of which lies a novel reading of the historical person of Socrates as the "real image" of the good. Schindler argues that a full response to the attack on reason introduced by Thrasymachus at the dialogue's outset awaits the revelation of goodness as the cause of truth. This revelation is needed because the good is what enables the mind to know and makes things knowable. When we read Socrates' display of the good against the horizon of the challenges posed by sophistry, otherwise disparate aspects of Plato's masterpiece turn out to play essential roles in the production of an integrated whole.
