Denn was ist Freiheit? Dasz man den Willen zur Selbstverantwortlichkeit hat.

The definition of morality: Morality is the idiosyncrasy of decadents having the hidden desire to revenge themselves upon life - and being successful.

And we should consider every day lost on which we have not danced at least once. And we should call every truth false which was not accompanied by at least one laugh.

Without the perpetual counterfeiting of the universe by number, man could not continue to live

Death. The certain prospect of death could sweeten every life with a precious and fragrant drop of levity- and now you strange apothecary souls have turned it into an ill-tasting drop of poison that makes the whole of life repulsive.

This life as you now live it and have lived it, you will have to live once more and innumerable times more; and there will be nothing new in it, but every pain and every joy and every thought and sigh and everything unutterably small or great in your life will have to return to you, all in the same succession and sequence - even this spider and this moonlight between the trees, and even this moment and I myself. The eternal hourglass of existence is turned upside down again and again, and you with it, speck of dust!

One must repay good and ill; but why just to the person who did us good or ill?
