On Truth and Lie in an Extra-Moral Sense
www.kth.seOnly through forgetfulness can man ever achieve the illusion of possessing a "truth" in the sense just designated. If he does not wish to be satisfied with truth in the form of a tautology—that is, with empty shells—then he will forever buy illusions for truths. What is a word? The image of a nerve stimulus in sounds.
