A tempestuous defence of Aristotle was made by George of Trebizond,
who was at this time translating, for Pope Nicholas V, works of both Plato
and Aristotle as well as many Greek Fathers. His Comparison of Plato and
Aristotle (1458) makes Aristotle a Christian hero and Plato a heretical villain.
George claims that Aristotle believed in creation out of nothing, in divine
providence, and in a Trinity of divine persons. Plato, on the other hand,
propounded disgusting doctrines such as the beauty of pederasty and the
transmigration of souls into animals, and encouraged gymnastics for both
sexes together in the nude. Devotion to Plato had led the Greek Church
into heresy and schism; Latin Aristotelians had combined philosophy with
orthodoxy. Only scholars who were more concerned with style than
content could prefer Plato to Aristotle.
Two cardinals entered the debate to redress the balance. Nicholas of
Cusa, for whom George had translated Plato’s Parmenides, wrote a dialogue,
On the Not Other, in which he stressed the limitations of both Aristotelian
logic and Platonic metaphysics, while endeavouring to build on both of
them in attaining knowledge of God, the divine Not-Other. More soberly,
Bessarion wrote a treatise, published in both Greek and Latin, entitled
Against the Calumniator of Plato. He pointed out that many Christian saints had
been admirers of Plato. While neither Plato nor Aristotle agreed at all fully
with Christian doctrine, the points of conX ict between them were few, a nd
there were as many points of similarity between Plato and Aristotle as
between Aristotle and Christianity.
Aristotle, he said, pace George of Trebizond, did not believe that God
freely created the world out of nothing, and Plato was much closer to the
Christian belief in divine providence. Aristotle, again, did not prove that
individual human souls were immortal. The way in which Aristotle
explains concept-formation by the inXuence of the agent intellect is very
close to Plato’s theory of human links to the Ideas in recollection. Bessarion
balances George’s citation of licentious passages from the dialogues with
others in which Plato exhorts to continence and virtue. Both Plato and
Aristotle were outstanding thinkers, sent by providence to bring humans
to the truth by diVerent paths. Plato’s anthropology, Bessarion maintains,
is closer to what life would have been without original sin; Aristotle gives a
more realistic account of fallen humanity.
By the 1460s it was universally accepted that the study of Plato was
appropriate for Catholic scholars in the West. The fall of Constantinople to
