Very rare edition ( the first, virtually unobtainable, had appeared in Venice, 1497). The treatise is a commentary on the famed Tahāfut al-Tahāfut, in which Averroes (1126–1198) defends the use of Aristotelian philosophy within Islamic thought and tries to create harmony between faith and philosophy. Agostino Nifo (born c. 1473, Sessa, Naples — died after 1538, possibly Salerno) was a philosopher noted for his development from an anti-Christian interpreter of Aristotelian philosophy into an influential Christian apologist for the immortality of the individual soul. While attending the University of Padua about 1490, Nifo studied the Averroist Aristotelianism of Nicoletto Vernia and Siger of Brabant, emphasizing the eternity of the world and an immortal, universal intellect subsuming the souls of all individuals at death. Later, however, he made a critical edition of Averroës’s commentaries on Aristotle with conclusions more open to Christian doctrine. Nifo's commentary is based on the Latin translation prepared in the 14th century by Calonymos ben Calonymos (Arles, 1286 – died after 1328).
