one may imagine, this primeval problem was not solved by exactly gentle answers and gentle means; perhaps there is nothing more awful and more sinister in the early history of man than his system of mnemonics. "Something is burnt in so as to remain in his memory: only that which never stops hurting remains in his memory." This is an axiom of the oldest (unfortunately also the longest) psychology in the world. It might even be said that wherever solemnity, seriousness, mystery, and gloomy colours are now found in the life of the men and of nations of the world, there is some survival of that horror which was once the universal concomitant of all promises, pledges, and obligations. The past, the past with all its length, depth, and hardness, wafts to us its breath, and bubbles up in us again, when we become "serious." When man thinks it necessary to make for himself a memory, he never accomplishes it without blood, tortures and sacrifice; the most dreadful sacrifices and forfeitures (among them the sacrifice of the first-born), the most loathsome mutilation (for instance, castration), the most cruel rituals of all the religious cults (for all religions are really at bottom systems of cruelty)—all these things originate from that instinct which found in pain its most potent mnemonic. In a certain sense the whole of asceticism is to be ascribed to this: certain ideas have got to be made inextinguishable, omnipresent, "fixed," with the object of hypnotising the whole nervous and intellectual system through these "fixed ideas"—and the ascetic methods and modes of life are the means of freeing those ideas from the competition of all other ideas so as to make them "unforgettable."
