Callicles

Callicles is thought to have been an ancient Athenian political philosopher. He figures prominently in Plato’s dialogue Gorgias, where he "presents himself as a no-holds-barred, bare-knuckled, clear-headed advocate of Realpolitik". In terms of dramatic action, his function in the dialogue is to provide a counter-argument to Plato's philosophical ideas. The absence of contemporaneous sources external to this single text attesting to his existence has suggested to some that he may be no more than a character created by Plato for the dialogue. In this vein, it has also been proposed that Callicles may have been devised by Plato as he imagined what kind of intellectual he might have become had he not met with Socrates and undergone his formative philosophical life under the latter's tutelage. He is the antithesis to Socrates.
