"Lately has risen amongst us a second Mahomet: and this second, if we do not take care, will exceed in greatness the first, by the dreadful consequences of his wicked doctrine, as the first has exceeded Plato. A disciple and rival of this philosopher in philosophy, in eloquence, and in science, he had fixed his residence in the Peloponnese. His common name was _Gemisthus_, but he assumed that of _Pletho_. Perhaps Gemisthus, to make us believe more easily that he was descended from heaven, and to engage us to receive more readily his doctrine and his new law, wished to change his name, according to the manner of the ancient patriarchs, of whom it is said, that at the time the name was changed they were called to the greatest things. He has written with no vulgar art, and with no common elegance. He has given new rules for the conduct of life, and for the regulation of human affairs; and at the same time has vomited forth a great number of blasphemies against the Catholic religion. He was so zealous a platonist that he entertained no other sentiments than those of Plato, concerning the nature of the gods, souls, sacrifices, &c. I have heard him myself, when we were together at Florence, say, that in a few years all men on the face of the earth would embrace with one common consent, and with one mind, a single and simple religion, at the first instructions which should be given by a single preaching. And when I asked him if it would be the religion of Jesus Christ, or that of Mahomet? he answered, 'Neither one nor the other; but a _third_, which will not greatly differ from _paganism_.' These words I heard with so much indignation, that since that time I have always hated him: I look upon him as a dangerous viper; and I cannot think of him without abhorrence." The pious writer might have been satisfied to have bestowed a smile of pity or contempt. When Pletho died, full of years and honours, the malice of his enemies collected all its venom. This circumstance seems to prove that his abilities must have been great indeed, to have kept such crowds silent. Several Catholic writers lament that his book was burnt, and regret the loss of Pletho's work; which, they say, was not designed to subvert the Christian religion, but only to unfold the system of Plato, and to collect what he and other philosophers had written on religion and politics.
