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.
Oracle
She allegedly also proclaimed that there was no man wiser than Socrates, to which Socrates said that, if so, this was because he alone was aware of his own ignorance. After this confrontation, Socrates dedicated his life to a search for knowledge that was one of the founding events of western philosophy. He claimed that she was "an essential guide to personal and state development." This oracle's last recorded response was given in 362 AD, to Julian the Apostate.
