Man lives consciously for himself, but is an unconscious instrument in the attainment of the historic, universal, aims of humanity.

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!

No one accuses without an underlying notion of punishment and revenge, even when he accuses his fate or himself. All complaint is accusation, all self-congratulation is praise.

Man is a rope, tied between beast and overman - a rope over an abyss. What is great in man is that he is a bridge and not an end: what can be loved in man is that he is an overture and a going under.

Whoever has witnessed another's ideal becomes his inexorable judge and as it were his evil conscience.

We hear only those questions for which we are in a position to find answers.
