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.
Symposium (Plato)
Alcibiades thought at the time that Socrates really only wanted him sexually, and by letting Socrates have his way with him he would entice Socrates to teach him everything he knew (217a). Yet Socrates made no move, and Alcibiades began to pursue Socrates "as if I were the lover and he my young prey!" (217c). When Socrates continually rebuffed him, Alcibiades began to view Socrates as the only true and worthy lover he had ever had. So he told Socrates that it seemed to him now that nothing could be more important than becoming the best man he could be, and Socrates was best fit to help him reach that aim (218c-d). Socrates responded that if he did have this power, why would he exchange his true (inner) beauty for the image of beauty that Alcibiades would provide. Furthermore, Alcibiades might be wrong and Socrates may be of no use to him (218e-219a). Alcibiades spent the night sleeping beside Socrates yet, to the deep humiliation of Alcibiades, Socrates made no sexual attempt (219b-d).
