"Our country has been populated by pioneers, and therefore it has in it more energy, more enterprise, more expansive power than any other in the wide world. They have shown the qualities of daring, endurance, and far-sightedness, of eager desire for victory and stubborn refusal to accept defeat, which go to make up the essential manliness of the American character. Above all, they have recognized in practical form the fundamental law of success in American life—the law of worthy work, the law of high, resolute endeavor. We have but little room among our people for the timid, the irresolute, and the idle; and it is no less true that there is scant room in the world at large for the nation with mighty thews that dares not to be great."

“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.”
