 Aristotle’s treatise is relevant for Avempace in its description of the various powers of the soul, i.e., nutritive, sense-perceptive, imaginative, rational faculties, although Avempace may have not had any Arabic translation of Aristotle’s De  anima.[25]  Avempace often digresses into general reflections; for instance, at the beginning of his chapter on the nutritive faculty he talks about possibility and impossibility. But, in other places, there are some references to Aristotle, for instance, when it comes to the imaginative faculty. Avempace writes that “The imaginative faculty is the faculty by which the ‘reasons’ (ma‛ani) of the sensibles are apprehended” (IB-S1a: 133. 3; IB-S1e: 106).
