Nietzsche on Objectivity
On the Geneology of Morals - Third Essay
Precisely because we seek knowledge, let us not be ungrateful to such resolute reversals of accustomed perspectives and valuations with which the spirit has, with apparent mischievousness and futility, raged against itself for so long: to see differently in this way for once, to want to see differently, is no small discipline and preparation of the intellect for its future 'objectivity'- the latter understood not as 'contemplation without interest' (which is a nonsensical absurdity), but as the ability to control one's Pro and Con and to dispose of them, so that one knows how to employ a variety of perspectives and affective interpretations in the service of knowledge.
Let us be on guard against the dangerous old conceptual fiction that posited a 'pure, will-less, painless, timeless knowing subject'; let us guard against the snares of such contradictory concepts as 'pure reason', 'absolute spirituality', 'knowledge in itself': these always demand that we should think of an eye that is completely unthinkable, an eye turned in no particular direction, in which the active and interpreting forces, through which alone seeing becomes seeing something, are supposed to be lacking; these always demand of the eye an absurdity and a nonsense. There is only a perspective seeing, only a perspective 'knowing'; and the more affects we allow to speak about one thing, the more eyes, different eyes, we can use to observe one thing, the more complete will our concept of this thing, our 'objectivity', be. But to eliminate the will altogether, to suspend each and every affect, supposing we were capable of this- what would that mean but to castrate the intellect?
