"What is the lesson to us to-day? Are we to go the way of the older civilizations? The immense increase in the area of civilized activity to-day, so that it is nearly coterminous with the world's surface; the immense increase in the multitudinous variety of its activities; the immense increase in the velocity of the world movement—are all these to mean merely that the crash will be all the more complete and terrible when it comes? We can not be certain that the answer will be in the negative; but of this we can be certain, that we shall not go down in ruin unless we deserve and earn our end. There is no necessity for us to fall; we can hew out our destiny for ourselves, if only we have the wit and the courage and the honesty."

“I don’t go so far as to think that the only good Indian is the dead Indian, but I believe nine out of every ten are, and I shouldn’t like to inquire too closely into the case of the tenth.”

“The most vicious cowboy has more moral principle than the average Indian.”

“By God, if you try anything like that, I'll kick you, I'll bite you, I'll kick you in the balls. I'll do anything to you — you'd better leave me alone.”

“When a judge decides a constitutional question, when he decides what the people as a whole can or cannot do, the people should have the right to recall that decision if they think it wrong. We should hold the judiciary in all respect; but it is both absurd and degrading to make a fetish of a judge or of anyone else.”

“If there ever was a pursuit which stultified itself by its very conditions, it is the pursuit of pleasure as the all-sufficing end of life. Happiness can not come to any man capable of enjoying true happiness unless it comes as the sequel to duty well and honestly done. To do that duty you need to have more than one trait.”
