Such, at least, was the hatred in the heart of Savonarola. He was making war against no trivial human sins, but against godless and thankless quiescence, against getting used to happiness, the mystic sin by which all creation fell. He was preaching that severity which is the sign-manual of youth and hope. He was preaching that alertness, that clean agility and vigilance, which is as necessary to gain pleasure as to gain holiness, as indispensable in a lover as in a monk. A critic has truly pointed out that Savonarola could not have been fundamentally anti-æsthetic, since he had such friends as Michael Angelo, Botticelli, and Luca della Robbia. The fact is that this purification and austerity are even more necessary for the appreciation of life and laughter than for anything else. To let no bird fly past unnoticed, to spell patiently the stones and weeds, to have the mind a storehouse of sunset, requires a discipline in pleasure, and an education in gratitude.
The civilisation which surrounded Savonarola on every side was a civilisation which had already taken the wrong turn, the turn that leads to endless inventions and no discoveries, in which new things grow old with confounding rapidity, but in which no old things ever grow new. The monstrosity of the crimes of the Renaissance was not a mark of imagination; it was a mark, as all monstrosity is, of the loss of imagination. It is only when a man has really ceased to see a horse as it is, that he invents a centaur, only when he can no longer be surprised at an ox, that he worships the devil. Diablerie is the stimulant of the jaded fancy; it is the dram-drinking of the artist. Savonarola addressed himself to the hardest of all earthly tasks, that of making men turn back and wonder at the simplicities they had learnt to ignore. It is strange that the most unpopular of all doctrines is the doctrine which declares the common life divine. Democracy, of which Savonarola was so fiery an exponent, is the hardest of gospels; there is nothing that so terrifies men as the decree that they are all kings. Christianity, in Savonarola's mind, identical with democracy, is the hardest of gospels; there is nothing that so strikes men with fear as the saying that they are all the sons of God.
