For what purpose humanity is there should not even concern us: why you are here, that you should ask yourself: and if you have no ready answer, then set for yourself goals, high and noble goals, and perish in pursuit of them!

Not necessity, not desire - no, the love of power is the demon of men. Let them have everything - health, food, a place to live, entertainment - they are and remain unhappy and low-spirited: for the demon waits and waits and will be satisfied.

The secret of reaping the greatest fruitfulness and the greatest enjoyment from life is to live dangerously.

Human existence basically is──a never to be completed imperfect tense.

Whoever has character also has his typical experience, which returns over and over again.

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.
