Friedrich Nietzsche

The Will Too Power

Book Three

473 The intellect cannot criticize itself, simply because it cannot be compared with other species of intellect and because its capacity to know would be revealed only in the presence of “true reality,” i.e., because in order to criticize the intellect we should have to be a higher being with “absolute knowledge.” This presupposes that, distinct from every perspective kind of outlook or sensual-spiritual appropriation, something exists, an “in-itself.”- But the psychological derivation of the belief in things forbids us to speak of ”things-in-themselves.”
