This humanism was in fact pagan, and became more and more so as its sphere widened in the fifteenth century. Its representatives, whom we have already described as the advance guard of an unbridled individualism, display as a rule such a character that even their religion, which is sometimes professed very definitely, becomes a matter of indifference to us. They easily got the name of atheists, if they showed themselves indifferent to religion and spoke freely against the Church; but not one of them ever professed, or dared to profess, a formal, philosophical atheism. If they sought for any leading principle, it must have been a kind of superficial rationalism - a careless inference from the many and contradictory opinions of antiquity with which they busied themselves, and from the discredit into which the Church and her doctrines had fallen This was the sort of reasoning which was near bringing Galeotto Martio to the stake, had not his former pupil, Pope Sixtus IV, perhaps at the request of Lorenzo de' Medici, saved him from the hands of the Inquisition. Galeotto had ventured to write that the man who lived uprightly, and acted according to the natural law born within him, would go to heaven, whatever nation he belonged to.
