"What then is truth? A movable host of metaphors, metonymies, and anthropomorphisms: in short, a sum of human relations which havebeen poetically and rhetorically intensified, transferred, and embellished, and which, after long usage, seem to a people to be fixed, canonical, and binding. Truths are illusions which we have forgotten are illusions; they are metaphors that have become worn out and have been drained of sensuous force, coins which have lost their embossing and are now considered as metal and no longer as coins."
"We have no organ at all for knowledge, for "truth": we "know" (or believe or imagine) precisely as much as may be useful in the interest of the human herd, the species: and even what is here called "usefulness" is in the end only a belief, something imagined and perhaps precisely that most fatal piece of stupidity by which we shall one day perish."
"Could truth perhaps be a woman who has reasons for not permitting her reasons to be seen? Could her name perhaps be--to speak Greek--Baubo?... Oh, those Greeks! They understood how to live: to do that it is necessary to stop bravely at the surface, the fold, the skin, to adore the appearance, to believe in forms, in tones, in words, in the whole Olympus of appearance! Those Greeks were superficial--out of profundity!"
