Again, it is Nordau who chiefly voices the second of the objections noted at the beginning of this chapter, though here many another self-confessed serpent of wisdom follows him. Nietzsche, he says, tore down without building up, and died without having formulated any workable substitute for the Christian morality he denounced. Even to the reader who has got no further into Nietzsche than the preceding chapters of this book, the absurdity of such a charge must be manifest without argument. No man, indeed, ever left a more comprehensive system of ethics, not even Comte or Herbert Spencer, and if it be true that he scattered it through a dozen books and that he occasionally modified it in some of its details, it is equally true that his fundamental principles were always stated with perfect clearness and that they remained substantially unchanged from first to last. But even supposing that he had died before he had arranged his ideas in a connected and coherent form, and that it had remained for his disciples to deduce and group his final conclusions, and to rid the whole of inconsistency--even then it would have been possible to study those conclusions seriously and to accept them for what they were worth. Nordau lays it down as an axiom that a man cannot be a reformer unless he proposes some ready-made and perfectly symmetrical scheme of things to take the place of the notions he seeks to overturn, that if he does not do this he is a mere hurler of bricks and shouter of blasphemies. But all of us know that this is not true. Nearly every considerable reform the world knows has been accomplished, not by one man, but by many men working in series. It seldom happens, indeed, that the man who first points out the necessity for change lives long enough to see that change accomplished, or even to define its precise manner and terms. Nietzsche himself was not the first critic of Christian morality, nor did he so far dispose of the question that he left no room for successors. But he made a larger contribution to it than any man had ever made before him, and the ideas he contributed were so acute and so convincing that they must needs be taken into account by every critic who comes after him.
