All religions bear traces of the fact that they arose during the intellectual immaturity of the human race - before it had learned the obligations to speak the truth. Not one of them makes it the duty of its god to be truthful and understandable in his communications.
Verily, a polluted stream is man. One must actually be a sea to take in a polluted stream without becoming impure. Behold, I teach you the superman: he is the this sea, in him can your great contempt go under.
The reasons and purposes for habits are always lies that are added only after some people begin to attack these habits and to ask for reasons and purposes. At this point the conservatives of all ages are thoroughly dishonest: they add lies.
Historical refutation as the definitive refutation.- In former times, one sought to prove that there is no God - today one indicates how the belief that there is a God arose and how this belief acquired its weight and importance: a counter-proof that there is no God thereby becomes superfluous.- When in former times one had refuted the 'proofs of the existence of God' put forward, there always remained the doubt whether better proofs might not be adduced than those just refuted: in those days atheists did not know how to make a clean sweep.
When, however, you have an enemy, then do not requite him good for evil: for that would shame him. Instead, prove that he did some good for you. And rather be angry than put to shame! And when you are cursed, I do not like it that you want to bless. Rather curse a little also! And if you are done a great injustice, then quickly add five small ones. Hideous to behold is he who is obsessed with an injustice.
A noble soul is not the one that can manage the highest flights but the one that rises very little and falls very little but always dwells in a free, resplendent atmosphere and altitude.
Science offends the modesty of all real women. It makes them feel as though it were an attempt to peek under their skin--or, worseyet, under their dress and ornamentation!
It may be that until now there has been no more potent means for beautifying man himself than piety: it can turn man into so much art, surface, play of colors, graciousness that his sight no longer makes one suffer.---
