"In the Middle Ages and in the Renaissance (which was, in certain times and respects, a much gloomier period) this idea of the skeleton had a vast influence in freezing the pride out of all earthly pomps and the fragrance out of all fleeting pleasures. But it was not, surely, the mere dread of death that did this, for these were ages in which men went to meet death singing; it was the idea of the degradation of man in the grinning ugliness of his structure that withered the juvenile insolence of beauty and pride. And in this it almost assuredly did more good than harm. There is nothing so cold or so pitiless as youth, and youth in aristocratic stations and ages tended to an impeccable dignity, an endless summer of success which needed to be very sharply reminded of the scorn of the stars. It was well that such flamboyant prigs should be convinced that one practical joke, at least, would bowl them over, that they would fall into one grinning man-trap, and not rise again. That the whole structure of their existence was as wholesomely ridiculous as that of a pig or a parrot they could not be expected to realize; that birth was humorous, coming of age humorous, drinking and fighting humorous, they were far too young and solemn to know. But at least they were taught that death was humorous."
