The Gorgias (Greek: Γοργίας) is a dialogue by Plato depicting a debate between Socrates and a prominent sophist. It is set at the home of Callicles, where Socrates and his friend Chaerephon are invited to an audience with Gorgias after he has given a speech. The discussion centres on the nature of the art of rhetoric, which Socrates criticises because it does not teach how to use the skills it imparts justly.
