“We are so fond of being out in Nature because it has no opinions of us.”

“One sticks to an opinion because he prides himself on having come to it on his own, and another because he has taken great pains to learn it and is proud to have grasped it: and so both do so out of vanity.”

“It is not conflict of opinions that has made history so violent but conflict of belief in opinions, that is to say conflict of convictions.”

“we often refuse to accept an idea merely because the way in which it has been expressed is unsympathetic to us.”

“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.”

“We talk so abstractly about poetry because all of us are usually bad poets.”

“When we have to change an opinion about any one, we charge heavily to his account the inconvenience he thereby causes us.”
