Nietzsche devoted a great deal of time during his first period of activity to similar examinations of Christian ideas and he did a great deal to supplement the historical investigations of those English and German savants whose ruthless exposure of fictions and frauds gave birth to what we now call the higher criticism. But his chief service was neither in the field of historical criticism nor in that of the criticism of dogmas. Toward the end of his life he left the business of examining biblical sources to the archeologists and historians, whose equipment for the task was necessarily greater than his own, and the business of reducing Christian logic to contradiction and absurdity to the logicians. Thereafter, his own work took him a step further down and in the end he got to the very bottom of the subject. The answer of the theologians had been that, even if you denied the miracles, the gospels, the divinity of Christ and his very existence as an actual man, you would have to admit that Christianity itself was sufficient excuse for its own existence; that it had made the world better and that it provided a workable scheme of life by which men could live and die and rise to higher things. This answer, for awhile, staggered the agnostics and Huxley himself evidently came near being convinced that it was beyond rebuttal.[9] But it only made Nietzsche spring into the arena more confident than ever. "Very well," he said, "we will argue it out. You say that Christianity has made the world better? I say that it has made it worse! You say that it is comforting and uplifting? I say that it is cruel and degrading! You say that it is the best religion mankind has ever invented? I say it is the most dangerous!"
Having thus thrown down the gage of battle, Nietzsche proceeded to fight like a Tartar, and it is but common fairness to say that, for a good while, he bore the weight of his opponents' onslaught almost unaided. The world was willing enough to abandon its belief in Christian supernaturalism and as far back as the early 80's the dignitaries of the Church of England--to employ a blunt but expressive metaphor--had begun to get in out of the wet. But the pietists still argued that Christianity remained the fairest flower of civilization and that it met a real and ever-present human want and made mankind better. To deny this took courage of a decidedly unusual sort--courage that was willing to face, not only ecclesiastical anathema and denunciation, but also the almost automatic opposition of every so-called respectable man. But Nietzsche, whatever his deficiencies otherwise, certainly was not lacking in assurance, and so, when he came to write "Der Antichrist" he made his denial thunderous and uncompromising beyond expression. No medieval bishop ever pronounced more appalling curses. No backwoods evangelist ever laid down the law with more violent eloquence. The book is the shortest he ever wrote, but it is by long odds the most compelling. Beginning allegro, it proceeds from forte, by an uninterrupted crescendo to allegro con moltissimo molto fortissimo. The sentences run into mazes of italics, dashes and asterisks. It is German that one cannot read aloud without roaring and waving one's arm.
Christianity, says Nietzsche, is the most dangerous system of slave-morality the world has ever known. "It has waged a deadly war against the highest type of man. It has put a ban on all his fundamental instincts. It has distilled evil out of these instincts. It makes the strong and efficient man its typical outcast man. It has taken the part of the weak and the low; it has made an ideal out of its antagonism to the very instincts which tend to preserve life and well-being.... It has taught men to regard their highest impulses as sinful--as temptations."[10] In a word, it tends to rob mankind of all those qualities which fit any living organism to survive in the struggle for existence.
