 Some regard Nietzsche’s 1873 unpublished essay, “On Truth and Lies in a Nonmoral Sense” (“Über Wahrheit und Lüge im außermoralischen Sinn”) as a keystone in his thought; some believe that it is a peripheral, conflicted and non-representative fragment in his writings. In this essay, Nietzsche rejects the idea of universal constants, and claims, presumably as a truth, that what we call “truth” is only “a mobile army of metaphors, metonyms, and anthropomorphisms.” His view at this time is that arbitrariness prevails within human experience: concepts originate via the transformation of nerve stimuli into images, and “truth” is nothing more than the invention of fixed conventions for practical purposes, especially those of repose, security and consistency. Nietzsche regards our “knowledge” as human, all-too-human, mostly a matter of self-deception that issues from a deep-seated exercise of metaphorical thought. Viewing our existence from a vast and sobering distance, Nietzsche further notes that there was an eternity before human beings came into existence, and believes that after humanity dies out, nothing significant will have changed in the great scheme of things.
