"The man who works, the man who does great deeds, in the end dies as surely as the veriest idler who cumbers the earth's surface; but he leaves behind him the great fact that he has done his work well. So it is with nations. While the nation that has dared to be great, that has had the will and the power to change the destiny of the ages, in the end must die, yet no less surely the nation that has played the part of the weakling must also die; and whereas the nation that has done nothing leaves nothing behind it, the nation that has done a great work really continues, though in changed form, to live forevermore. The Roman has passed away exactly as all the nations of antiquity which did not expand when he expanded have passed away; but their very memory has vanished, while he himself is still a living force throughout the wide world in our entire civilization of today, and will so continue through countless generations, through untold ages."

“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.”
