Abstract
This paper deals with the philosophical purpose of the Gorgias. I argue that this dialogue, both in its form and content, yields a dramatic demonstration that the success of the Socratic inquiry depends on the character of his interlocutors and their sense of what is shameful or not. To read the Gorgias is to inquire whether Socrates’ refutations have demonstrated anything. Although there is no definition of justice, happiness or the art of rhetoric, the dialogue nevertheless shows that justice and trustworthiness concern both the practitioners of rhetoric and those of dialectic.
