Anti-Platonism in De Anima III.5

Famously, Plato argues that the soul pre-exists the body, continues to exist after the body dies, and can come to exist afterwards in another body. Aristotle argues against the transmigration of souls in On Generation and Corruption and for the most part appears not to endorse these Platonic doctrines. But in De Anima III.5 Aristotle also seems to argue that a part of the soul, usually dubbed the nous poiētikos, is separable from the body and eternal. This has presented interpreters of Aristotle with a problem: how can we reconcile Aristotle the naturalist philosopher with the apparently Platonist philosopher of De Anima III.5? Can we understand Aristotle’s position in De Anima III.5 in a way that does not conflict with the anti-Platonism he expresses in texts like On Generation and Corruption? I will argue that we can and offer an interpretation of De Anima III.5 that does not commit Aristotle to the position that the human soul is eternal. Even if Plato is right about the concept of the human soul, about what the human soul is in its own nature, he is wrong on ontological grounds. There are no eternal human souls.
