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.
Groundwork of the Metaphysic of Morals
According to Kant, we think of ourselves as having free will. This lets us make judgments such as “you ought to have done that thing that you did not do.” Kant argues that this notion of freedom cannot be derived from our experience. We can be sure that this concept of freedom doesn't come from experience because experience itself contradicts it. Our experience is of everything in the sensible world and in the sensible world, everything that happens does so in accord with the laws of nature and there is no room for a free will to influence events.
