he flows over, he consumes himself, he does not spare himself,—and does all this with fateful necessity, irrevocably, involuntarily, just as a river involuntarily bursts its dams. But, owing to the fact that humanity has been much indebted to such explosives, it has endowed them with many things, for instance, with a kind of _higher morality_.... This is indeed the sort of gratitude that humanity is capable of: it _misunderstands_ its benefactors. 45 _The criminal and his like._—The criminal type is the type of the strong man amid unfavourable conditions, a strong man made sick. He lacks the wild and savage state, a form of nature and existence which is freer and more dangerous, in which everything that constitutes the shield and the sword in the instinct of the strong man, takes a place by right. Society puts a ban upon his virtues; the most spirited instincts inherent in him immediately become involved with the depressing passions, with suspicion, fear and dishonour. But this is almost the recipe for physiological degeneration. When a man has to do that which he is best suited to do, which he is most fond of doing, not only clandestinely, but also with long suspense, caution and ruse, he becomes anæmic; and inasmuch as he is always having to pay for his instincts in the form of danger, persecution and fatalities, even his feelings begin to turn against these instincts—he begins to regard them as fatal. It is society, our tame, mediocre, castrated society, in which an untutored son of nature who comes to us from his mountains or from his adventures at sea, must necessarily degenerate into a criminal. Or almost necessarily: for there are cases in which such a man shows himself to be stronger than society: the Corsican Napoleon is the most celebrated case of this. Concerning the problem before us, Dostoiewsky’s testimony is of importance—Dostoiewsky who, incidentally, was the only psychologist from whom I had anything to learn: he belongs to the happiest windfalls of my life, happier even than the discovery of Stendhal. This profound man, who was right ten times over in esteeming the superficial Germans low, found the Siberian convicts among whom he lived for many years,—those thoroughly hopeless criminals for whom no road back to society stood open—very different from what even he had expected,—that is to say carved from about the best, hardest and most valuable material that grows on Russian soil.[7] Let us generalise the case of the criminal; let us imagine creatures who for some reason or other fail to meet with public approval, who know that they are regarded neither as beneficent nor useful,—the feeling of the Chandala, who are aware that they are not looked upon as equal, but as proscribed, unworthy, polluted. The thoughts and actions of all such natures are tainted with a subterranean mouldiness; everything in them is of a paler hue than in those on whose existence the sun shines. But almost all those
