Nietzsche, “On Truth and Lying In An Extra-Moral Sense”

“What is truth? a mobile army of metaphors, metonyms, anthropomorphisms, in short, a sum of human relations which were poetically and rhetorically heightened, transferred, and adorned, and after long use seem solid, canonical, and binding to a nation. Truths are illusions about which it has been forgotten that they are illusions, worn-out metaphors without sensory impact, coins which have lost their image and now can be used only as metal, and no longer as coins.”
