 The activities of the rational soul are not generated from it by virtue of its being rational. Therefore, I can reply to my critic that a material agent may act upon it from the aspect of its not being rational, a fortiori that an immaterial agent may act upon it. Moreover, the human soul is not entirely separate from matter, but only the acquired intellect, which is the agent intellect. Its activity takes place only through the intermediary of the intellect that is acted upon, which Aristotle considered to be subject to generation and destruction. (ʿEzer ha-Dat: 140)
