Callicles (/ˈkælɪkliːz/; Greek: Καλλικλῆς; c. 484 – late 5th century BCE) was an ancient Athenian political philosopher best remembered for his role in Plato’s dialogue Gorgias, where he "presents himself as a no-holds-barred, bare-knuckled, clear-headed advocate of Realpolitik." While he provides a counter-argument to Plato’s philosophical ideas, there is belief that he may be no more than a character created by Plato for the dialogue. Another idea proposed is that Callicles is a fragment of what Plato may be, had he not Socrates to guide him. He is the antithesis to Socrates.
Callicles is depicted as a young student of the sophist Gorgias. In the dialogue named for his teacher, he argues the position of an oligarchic amoralism, stating that it is natural and just for the strong to dominate the weak and that it is unfair for the weak to resist such oppression by establishing laws to limit the power of the strong. He asserts that the institutions and moral code of his time were not established by gods but by men who naturally were looking after their own interests.
Despite the scant surviving sources for his thought, he served as influential to modern political philosophy, notably including Friedrich Nietzsche.
Callicles poses an immoralist argument that consisted of 4 parts: “(1) a critique of conventional justice, (2) a positive account of ‘justice according to nature’, (3) a theory of the virtues, and (4) a hedonistic conception of the good.” For the first aspect of the argument, Callicles supports the ruling of strong individuals and criticizes the weak for trying to undermine them. He views democracy as “the tyranny of the many over the exceptional individual,” and stresses that society should allow themselves to be ruled by these strong individuals. This ties in to the second part of his argument – Callicles cites nature, saying “[nature] shows that this is what justice has been decided to be: that the superior rule the inferior and have a greater share than they.” Socrates argues that men should work together, while Callicles stresses that the superior individuals should be the one to rule, reaffirming this idea of Socrates and Callicles being antagonists.
