What does not destroy me, makes me stronger.

Whatever a theologian regards as true must be false: there you have almost a criterion of truth.

You must be born for your physician, otherwise you are bound to perish because of your physician.

So live your life of obedience and of war! What matter about long life! What warrior wisheth to be spared!

But thus I counsel you, my friends: Mistrust all in whom the impulse to punish is powerful. They are people of a low sort and stock; the hangmen and the bloodhound look out of their faces. Mistrust all who talk much of their justice! Verily, their souls lack more than honey. And when they call themselves the good and the just, do not forget that they would be pharisees, if only they had-power.

Whoever wants to set a good example must add a grain of foolishness to his virtue: then others can imitate and yet at the same time surpass the one they imitate-which human beings love to do.

One must first be firmly set in oneself, one must stand securely on one's own two legs otherwise one cannot love at all.
