The world is a dangerous place to live, not because of the people who are evil, but because of the people who don't do anything about it.

You should be the change that you want to see in the world.

Sometimes I wonder whether the world is being run by smart people who are putting us on, or by imbeciles who really mean it.

An eye for an eye will make the whole world blind.

Don't go around saying the world owes you a living. The world owes you nothing. It was here first.

It is curious that physical courage should be so common in the world and moral courage so rare.

Why change the world when we can change ourselves?

What really interests me is whether God had any choice in the creation of the world. Remark to Ernst Straus, one of his assistants.

I am not an Athenian or a Greek, but a citizen of the world.

To be yourself in a world that is constantly trying to make you something else is the greatest accomplishment.
