Abstract
In De Anima III 10, Aristotle introduces the notion of phantasía logistikē as one of the principles of rational action. On the basis of some texts from De Anima and the Nicomachean Ethics, the paper seeks to interpret the place of that type of imagination in practical reasoning. To that e ect, it rst sets forth Aristotle’s doctrine regarding the principles of action and the issue of their articulation, and then goes on to discuss the role of rational imagination in the con guration of the object of desire.
