Who is Callicles from Gorgias and what is their importance?

Callicles of Acharnae in Attica, the Athenian Demos, was the son of Pyrilampes. He is one of the three main subjects in Gorgias. Callicles takes part in the dialogue when Socrates recognizes that his knowledge and frankness benefit the discussion. Socrates later accuses him of having evil spirit. Callicles has a high regard for the art of business, and he encourages Socrates to undertake it. An accomplished and worldly man, Callicles is direct and can defend himself, although he has a quick temper, which is easily provoked. Callicles is the enemy of sophists and despises philosophy.
