You are a vain fellow. You want to be a hero. That is why you do such silly things. A hero!... I don't quite know what that is: but, you see, I imagine that a hero is a man who does what he can. The others do not do it.

Each man must learn his own ideal and try to accomplish it: that is a surer way of progress than to take the ideas of another.

Thousands of animals (now billions) are butchered every day without a shadow of remorse. It cries vengeance upon all the human race.

Passion is like genius: a miracle.

The friend who understands you, creates you.

There is no joy other than the joy of creating. There is no man who is truly alive other than one who is creating. All others are just shadows on the earth with nothing to do with being alive. The joy of living, whether it is love or action, is the joy of creating.

To understand everything is to hate nothing.
