“4. The falseness of an opinion is not for us any objection to it: it is here, perhaps, that our new language sounds most strangely. The question is, how far an opinion is life-furthering, life- preserving, species-preserving, perhaps species-rearing, and we are fundamentally inclined to maintain that the falsest opinions (to which the synthetic judgments a priori belong), are the most indispensable to us, that without a recognition of logical fictions, without a comparison of reality with the purely IMAGINED world of the absolute and immutable, without a constant counterfeiting of the world by means of numbers, man could not live—that the renunciation of false opinions would be a renunciation of life, a negation of life. TO RECOGNISE UNTRUTH AS A CONDITION OF LIFE; that is certainly to impugn the traditional ideas of value in a dangerous manner, and a philosophy which ventures to do so, has thereby alone placed itself beyond good and evil.”

“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.”

“The logic of worldly success rests on a fallacy: the strange error that our perfection depends on the thoughts and opinions and applause of other men! A weird life it is, indeed, to be living always in somebody else's imagination, as if that were the only place in which one could at last become real!”

“Our second danger is to associate tradition with the immovable; to think of it as something hostile to all change; to aim to return to some previous condition which we imagine as having been capable of preservation in perpetuity, instead of aiming to stimulate the life which produced that condition in its time. . . . a tradition without intelligence is not worth having . . .”

“I considered the case and realized that if something can exist in opinion without existing in reality, or exist in reality without existing in opinion, the conclusion is that of the two parallel lives, only opinion is necessary – not reality, which is only a secondary consideration.”

“There is a very popular opinion that choosing life is inherently superior to choosing death. This belief that life isinherently preferable to death is one of the most widespread superstitions. This bias constitutes one of the most obstinate mythologies of the human species.”
