[Sidenote: Cosmo de' Medici. Florence.] As if to prove that the impending crisis was not the offspring of human intentions, and not occasioned by any one man, though that man might be the sovereign pontiff, Nicolas V. found in his patronage of letters and art a rival and friend in Cosmo de' Medici. An instructive incident shows how great a change had taken place in the sentiments of the higher classes: Cosmo, the richest of Italians, who had lavished his wealth on palaces, churches, hospitals, libraries, was comforted on his death-bed, not, as in former days would have been the case, by ministers of religion, but by Marsilius Ficinus, the Platonist, who set before him the arguments for a future life, and consoled his passing spirit with the examples and precepts of Greek philosophy, teaching him thereby to exchange faith for hope, forgetting that too often hopes are only the day-dreams of men, not less unsubstantial and vain than their kindred of the night. Ficinus had perhaps come to the conviction that philosophy is only a higher stage of theology, the philosopher a very enlightened theologian. [Sidenote: Reappearance of Platonism in Italy.] He was the representative of Platonism, which for so many centuries had been hidden from the sight of men in Eastern monasteries since its overthrow in Alexandria, and which was now emerging into existence in the favouring atmosphere of Italy. His school looked back with delight, and even with devotion, to the illustrious pagan times, commemorating by a symposium on November 13th the birthday of Plato. The Academy of Athens was revived in the Medicean gardens of Florence. Not that Ficinus is to be regarded as a servile follower of the great philosopher. [Sidenote: Doctrines of Marsilius Ficinus.] He alloyed the doctrines of Plato with others derived from a more sinister source--the theory of the Mohammedan Averroes, of which it was an essential condition that there is a soul of humanity, through their relations with which individual souls are capable of forming universal ideas, for such, Averroes asserted, is the necessary consequence of the emanation theory.
