It should be noted that for Aristotle soul and nous are not the same. He did not rule out the possibility that nous might survive without the rest of the soul, as in Plato, but he specifically says that this immortal nous does not include any memories or anything else specific to an individual's life. In his Generation of Animals Aristotle specifically says that while other parts of the soul come from the parents, physically, the human nous, must come from outside, into the body, because it is divine or godly, and it has nothing in common with the energeia of the body.[30] This was yet another passage which Alexander of Aphrodisias would link to those mentioned above from De Anima and the Metaphysics in order to understand Aristotle's intentions.
