Free will in antiquity
In Plato's Gorgias (and in the Protagoras 345c4-e6), Socrates argues that no one does wrong willingly, one of the most famous doctrines to be associated with him. When framed in modern (Western) terms, the implication is that it is ignorance, rather that free individual agency, that is responsible for morally wrong actions.
Free will in antiquity
One view, going back to the 19th century historian Carlo Giussani, is that Epicurus' atomic swerves are involved directly in every case of human free action, not just somewhere in the past that breaks the causal chain of determinism. In 1928 Cyril Bailey agreed with Giussani that the atoms of the mind-soul provide a break in the continuity of atomic motions, otherwise actions would be necessitated. Bailey imagined complexes of mind-atoms that work together to form a consciousness that is not determined, but also not susceptible to the pure randomness of individual atomic swerves, something that could constitute Epicurus' idea of actions being "up to us" (πὰρ' ἡμάς). Bailey states that Epicurus did not "identify" freedom of the will with chance.
