Abstract

The main target of this paper is to provide a basis for the thesis that the core of Aristotle’s theory of human agency lies in the fact that the agent is in a relevant sense able to do otherwise. To this effect, a distinction is drawn between Aristotelian theory of action, and his moral psychology. The former is taken to be governed by the notion of a power to choose between contraries when the agent is about to do something, whereas the latter is focused on the notion of character, which imposes fixity and regularity to the agent’s actions. The distinction proposed is reached at by means of a reappraisal of NE 1112a31-33, passage in which Aristotle declares that (practical) intellect is a cause alongside nature, chance, and necessity.
