Abstract

This essay presents an interpretation of the theory of animal movement that emphasizes the place Aristotle accords the good as the object of desire and the coordinate importance he assigns to desire and discernment. This interpretation is based on two competing models: the desire-based model, where the shape of the account of any action is based on some one occurrent desire; and the good-based model, where the account starts from some object aimed at as good. It is argued that the texts of De Anima 3. 9-11 better fit the good-based model of animal motion than the desire-based model.
