Friedrich Wilhelm Nietzsche,
The Will to Power: An Attempted Transvaluation of All Values…
“ The valuation, "I believe that this and that is so," is the essence of "truth." In all valuations, the conditions of preservation and of growth find expression. All our organs and senses of knowledge have been developed only in view of the conditions of preservation and growth. The trust in reason and its categories, the trust in dialectics, and also the valuation of logic, prove only that experience has taught the usefulness of these things to life: not their "truth." ”
