once paid a great sum for a collection of cabalistic manuscripts which turned out to be forgeries; and the story might well stand as a parable of all he ever seemed to gain in the way of actual knowledge. He had sought knowledge, and passed from system to system, and hazarded much; but less for the sake of positive knowledge than because he believed there was a spirit of order and beauty in knowledge, which would come down and unite what men's ignorance had divided, and renew what time had made dim. And so while his actual work has passed away, yet his own qualities are still active, and he himself remains, as one alive in the grave, caesiis et vigilibus oculis, as his biographer describes him, and with that sanguine clear skin, decenti rubore interspersa, as with the light of morning upon it; and he has a true place in that group of great Italians who fill the end of the fifteenth century with their names, he is a true humanist. For the essence of humanism is that one belief of which he seems never to have doubted, that nothing which has ever interested living men and women can wholly lose its vitality—no language they have spoken, nor oracle by which they have hushed their voices, no dream which has once been entertained by actual human minds, nothing about which they have ever been passionate or expended time and zeal.
