Far smaller and far slower social changes in earlier periods triggered civil wars, rebellions, and violent intellectual and spiritual crises. The extreme social transformations of this century have caused hardly any stir. They have proceeded with a minimum of friction, with a minimum of upheavals, and, indeed, with a minimum of attention from scholars, politicians, the press, and the public. To be sure, this century of ours may well have been the cruelest and most violent in history, with its world and civil wars, its mass tortures, ethnic cleansings, genocides, and holocausts. But all these killings, all these horrors inflicted on the human race by this century's murderous "charismatics," hindsight clearly shows, were just that: senseless killings, senseless horrors, "sound and fury, signifying nothing." Hitler, Stalin, and Mao, the three evil geniuses of this century, destroyed. They created nothing.
