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.
Ethics
Virtue ethics describes the character of a moral agent as a driving force for ethical behavior, and it is used to describe the ethics of Socrates, Aristotle, and other early Greek philosophers. Socrates (469–399 BC) was one of the first Greek philosophers to encourage both scholars and the common citizen to turn their attention from the outside world to the condition of humankind. In this view, knowledge bearing on human life was placed highest, while all other knowledge was secondary. Self-knowledge was considered necessary for success and inherently an essential good. A self-aware person will act completely within his capabilities to his pinnacle, while an ignorant person will flounder and encounter difficulty. To Socrates, a person must become aware of every fact (and its context) relevant to his existence, if he wishes to attain self-knowledge. He posited that people will naturally do what is good if they know what is right. Evil or bad actions are the results of ignorance. If a criminal was truly aware of the intellectual and spiritual consequences of his or her actions, he or she would neither commit nor even consider committing those actions. Any person who knows what is truly right will automatically do it, according to Socrates. While he correlated knowledge with virtue, he similarly equated virtue with joy. The truly wise man will know what is right, do what is good, and therefore be happy.
