What is true
is not necessarily life
what is moral
is not necessarily true
what is life
a fiction?
Friedrich Nietzsche
Beyond Good and Evil
Section one on the prejudices of philosophers
4. The falseness of a judgment is, for us not necessarily an objection to a judgment; in this respect our new language may sound strangest The question is to what extent it is life-promoting, life-preserving, species-preserving, perhaps even species-cultivating And we are fundamentally inclined to claim that the falsest Judgments (which include the synthetic judgments a priori” are the most indispensable for us; that without accepting the fictions of logic, without measuring reality against the purely invented world of the unconditional and self-identical, without a constant falsification of the world by means of numbers, man could not live-that renouncing false judgments would mean renouncing life and a denial of life. To recognize untruth as a condition of life-that certainly means resisting accustomed value feelings in a dangerous way; and a philosophy that risks this would by that token alone place itself beyond good and evil.
