Friedrich Nietzsche

Convictions are more dangerous enemies of truth than lies.

Whoever does not know how to find the way to his ideal lives more frivolously and impudently than the man without an ideal.

Shedding one's skin. The snake that cannot shed its skin perishes. So do the spirits who are prevented from changing their opinions; they cease to be spirit.

He who has always spared himself much will in the end become sickly of so much consideration. Praised be what hardens!

One is most dishonest to one's god: he is not allowed to sin.

One must still have chaos in oneself to be able to give birth to a dancing star.

Once the decision has been made, close your ear even to the best counter argument: sign of a strong character. Thus an occasional will to stupidity.

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.

Woman was God's second mistake.

A woman may very well form a friendship with a man, but for this to endure, it must be assisted by a little physical antipathy.
