In his heart every man knows quite well that, being unique, he will be in the world only once and that no imaginable chance will for a second time gather together into a unity so strangely variegated an assortment as he is: he knows it but hides it like a bad conscience.
Out of damp and gloomy days, out of solitude, out of loveless words directed at us, conclusions grow up in us like fungus: one morning they are there, we know not how, and they gaze upon us, morose and gray. Woe to the thinker who is not the gardener but only the soil of the plants that grow in him.
Over immense periods of time the intellect produced nothing but errors. A few of these proved to be useful and helped to preserve the species: those who hit upon or inherited these had better luck in their struggle for themselves and their progeny. Such erroneous articles of faith... include the following: that there are things, substances, bodies; that a thing is what it appears to be; that our will is free; that what is good for me is also good in itself.
With deep men, as with deep wells, it takes a long time for anything that falls into them to hit bottom. Onlookers, who almost never wait long enough, readily suppose that such men are callous and unresponsive--or even boring.
Nobody can build the bridge for you to walk across the river of life, no one but you yourself alone. There are, to be sure, countless paths and bridges and demi-gods which would carry you across this river; but only at the cost of yourself; you would pawn yourself and lose. There is in the world only one way, on which nobody can go, except you: where does it lead? Do not ask, go along with it.
Nothing is beautiful, only man: on this piece of naivete rests all aesthetics, it is the first truth of aesthetics. Let us immediately add its second: nothing is ugly but degenerate man - the domain of aesthetic judgment is therewith defined.
You say 'I' and you are proud of this word. But greater than this- although you will not believe in it - is your body and its great intelligence, which does not say 'I' but performs 'I'.
Whereas the man of action binds his life to reason and its concepts so that he will not be swept away and lost, the scientific investigator builds his hut right next to the tower of science so that he will be able to work on it and to find shelter for himself beneath those bulwarks which presently exist.
You shall not steal! You shall not kill! Such words were once called holy; before them people bowrd their knees and heads, and removed their shoes. But I ask you: where have there ever been better thieves and killers in the world than such holy words have been? Is there not in all of life itself - robbing and killing? And when such words were called holy, was not truth itself thereby - killed?
It is so little true that martyrs offer any support to the truth of a cause that I am inclined to deny that any martyr has ever had anything to do with the truth at all.
People who comprehend a thing to its very depths rarely stay faithful to it forever. For they have brought its depths into the light of day: and in the depths there is always much that is unpleasant to see.
