In his efforts to account for the origin of Christianity, Nietzsche was less happy, and indeed came very near the border-line of the ridiculous. The faith of modern Europe, he said, was the result of a gigantic effort on the part of the ancient Jews to revenge themselves upon their masters. The Jews were helpless and inefficient and thus evolved a slave-morality. Naturally, as slaves, they hated their masters, while realizing, all the while, the unmanliness of the ideals they themselves had to hold to in order to survive. So they crucified Christ, who voiced these same ideals, and the result was that the outside world, which despised the Jews, accepted Christ as a martyr and prophet and thus swallowed the Jewish ideals without realizing it. In a word, the Jews detested the slave-morality which circumstances thrust upon them, and got their revenge by foisting it, in a sugar-coated pill, upon their masters.
It is obvious that this idea is sheer lunacy. That the Jews ever realized the degenerating effect of their own slave-morality is unlikely, and that they should take counsel together and plan such an elaborate and complicated revenge, is impossible. The reader of Nietzsche must expect to encounter such absurdities now and then. The mad German was ordinarily a most logical and orderly thinker, but sometimes the traditional German tendency to indulge in wild and imbecile flights of speculation cropped up in him.
