The essay examines Thomas Hill Green’s idealistic reading of Aristotle’s Metaphysics and De anima, starting from his “monopsychist” view of human understanding. His criticism of the Aristotelian notion of substance leads him to a recalibration of hylomorphism and a “noetization” of matter, which could be seen as an averroizing move. Green holds that there is only one “Eternal Consciousness” and that the individual thinking subjects are particular manifestations of it. As for Averroes’ unity of intellect, this idea derives from a (...) “left-wing” account of the potency of thought. But there are several other ontological, ethical, religious, and political consequences in making potency something essentially spiritual. The comparison between the two philosophers could help to throw light on the ‘obscure’ conception of “Eternal Consciousness”. (shrink)
