For Nietzsche, the goal is not to discover the unvarnished truth, for there is no such thing. Rather, the aim is to understand the forces—such as the need to communicate and the will to power—that have produced those ideas about truth that have driven philosophy through its long history.
Bizzell and Herzberg, 1170
"Let us be on guard against the dangerous old conceptual fiction that posited a ‘pure, will-less, plainless, 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 opposed to be lacking…. There is only a perspectival seeing, only a perspectival ‘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."
Nietzsche, On the Genealogy of Morals, III, 12
#word as metaphor
Every concept arises from the equation of unequal things.
We obtain the concept, as we do the form, by overlooking what is individual and actual…
What then is truth? …a sum of human relations which have been poetically and rhetorically intensified, transferred, and embellished, and which, after long usage, seem to a people to be fixed, canonical, and binding.
Nietzsche, On Truth and Lies in a Nonmoral Sense, 1174
