The Will to Power: An Attempted Transvaluation of All Values. Book III and IV

by Friedrich Wilhelm Nietzsche

C.

Then the "Will to Truth" would have to be examined psychologically: it is not a moral power, but a form of the Will to Power. This would have to be proved by the fact that it avails itself of every immoral means there is; above all, of the metaphysicians.

At the present moment we are face to face with the necessity of testing the assumption that moral values are the highest values, Method in research is attained only when all moral prejudices have been overcome: it represents a conquest over morality....

The aberrations of philosophy are the outcome of the fact that, instead of recognising in logic and the categories of reason merely a means to the adjustment of the world for utilitarian ends (that is to say, especially, a useful falsification), they were taken to be the criterion of truth—particularly of reality. The "criterion of truth" was, as a matter of fact, merely the biological utility of a systematic falsification of this sort, on principle: and, since a species of animals knows nothing more important than its own preservation, it was indeed allowable here to speak of "truth." Where the artlessness came in, however, was in taking this anthropocentric idiosyncrasy as the measure of things, as the canon for recognising the "real" and the "unreal": in short, in making a relative thing absolute. And behold, all at once, the world fell into the two halves, "real" and "apparent": and precisely that world which man's reason had arranged for him to live and to settle in, was discredited. Instead of using the forms as mere instruments for making the world manageable and calculable, the mad fancy of philosophers intervened, and saw that in these categories the concept of that world is given which does not correspond to the concept of the world in which man lives.... The means were misunderstood as measures of value, and even used as a condemnation of their original purpose....

The purpose was, to deceive one's self in a useful way: the means thereto was the invention of forms and signs, with the help of which the confusing multifariousness of life could be reduced to a useful and wieldy scheme.

But woe! a moral category was now brought into the game: no creature would deceive itself, no creature may deceive itself—consequently there is only a will to truth. What is "truth"?

The principle of contradiction provided the scheme: the real world to which the way is being sought cannot be in contradiction with itself, cannot change, cannot evolve, has no beginning and no end.

That is the greatest error which has ever been committed, the really fatal error of the world: it was believed that in the forms of reason a criterion of reality had been found—whereas their only purpose was to master reality, by misunderstanding it intelligently....
