God is dead. God remains dead. And we have killed him.

Cogito, ergo sum. I think, therefore I am.

The world is will and representation.

Hell is other people.

Man is condemned to be free.

The life of man, solitary, poor, nasty, brutish, and short.

Whereof one cannot speak, thereof one must be silent.

To know what you know and what you do not know, that is true knowledge.

One cannot step into the same river twice.

In the beginning was the Word.

To be is to be perceived.

The present is the only thing that has no end.

What does not kill me makes me stronger.

The soul, fortunately, has an interpreter — often an unconscious but still a faithful interpreter — in the eye.

Out of life's school of war: What does not kill me, makes me stronger.

The most courageous act is still to think for yourself. Aloud.

All that is gold does not glitter, not all those who wander are lost.
