Incorporeal Nous and the Science of the Soul in Aristotle’s De anima

In this essay I argue first that De anima 3.4–5 shows Aristotle answering affirmatively a question that he raises near the beginning of the work, namely, whether any of the soul’s affections are proper to it alone. Second, I argue that this initial conclusion reveals something important about the very first question that Aristotle broaches in the work, viz., the method and starting-points employed in the science of the soul. Aristotle’s position, I claim, shows that investigating the human soul is not merely an empirical concern discharged by natural science but also a rational concern discharged by logic, epistemology, and possibly even metaphysics. I defend these views against two rival interpretations of the passage, the “transcendental interpretation,” on which it does not describe a faculty immanent to human beings at all, and the “bad science interpretation,” on which it does but only as the result of Aristotle’s faulty physiology of cognition.
