Civilization is a race between disaster and education.

Seek knowledge from the cradle to the grave.

Study hard what interests you the most in the most undisciplined, irreverent and original manner possible.

The first idea the child must acquire is that of the difference between good and evil.

The only true wisdom is in knowing you know nothing.

The white man is very clever. He came quietly and peaceably with his religion. We were amused at his foolishness and allowed him to stay. Now he has won our brothers, and our clan can no longer act like one. He has put a knife on the things that held us together and we have fallen apart.

I am a part of everything that I have read.

You can never be overdressed or overeducated.
