 The third book, as indicated above, reviews a number of problematic issues in George of Trebizond’s treatment of Aristotle. Lighter topics—such as those related to sacrifices, and the reliance on poets and women—give way to more complex issues, such as Aristotle’s purported knowledge of Trinitarian dogma, his views on the immortality of the soul, and the place of providence in Peripatetic cosmology.  Particularly important here are the chapters centered on the impossibility of the individual immortality of the soul in via Aristotelis, since it contrasts with the eternity of the world defended in On the Heavens. Bessarion, conversely, finds both Averroes’ and Alexander of Aphrodisias’ interpretations of the soul acceptable according to the Aristotelian tenets, despite their contrast with the Christian faith.
