Alexander of Aphrodisias was a Peripatetic (Aristotelian) and his "On the Soul" (referred to as "De anima" in its traditional Latin title), explained that by his interpretation of Aristotle, potential intellect in man, that which has no nature but receives one from the active intellect, is material, and also called the "material intellect" ("nous hulikos") and it is inseparable from the body, being "only a disposition" of it. He argued strongly against the doctrine of immortality. On the other hand, he identified the active intellect ("nous poietikos"), through whose agency the potential intellect in man becomes actual, not with anything from within people, but with the divine creator itself. In the early Renaissance his doctrine of the soul's mortality was adopted by Pietro Pomponazzi against the Thomists and the Averroists. For him, the only possible human immortality is an immortality of a detached human thought, more specifically when the "nous" has as the object of its thought the active intellect itself, or another incorporeal intelligible form.
