"Gentlemen: you have now reached the last point. If anyone of you doesn't mean business let him say so now. An hour from now will be too late to back out. Once in, you've got to see it through. You've got to perform without flinching whatever duty is assigned you, regardless of the difficulty or the danger attending it. If it is garrison duty, you must attend to it. If it is meeting fever, you must be willing. If it is the closest kind of fighting, anxious for it. You must know how to ride, how to shoot, how to live in the open. Absolute obedience to every command is your first lesson. No matter what comes you mustn't squeal. Think it over — all of you. If any man wishes to withdraw he will be gladly excused, for others are ready to take his place."

“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.”
