"Exactly as each man, while doing first his duty to his wife and the children within his home, must yet, if he hopes to amount to much, strive mightily in the world outside his home, so our nation, while first of all seeing to its own domestic well-being, must not shrink from playing its part among the great nations without. Our duty may take many forms in the future as it has taken many forms in the past. Nor is it possible to lay down a hard-and-fast rule for all cases. We must ever face the fact of our shifting national needs, of the always-changing opportunities that present themselves. But we may be certain of one thing: whether we wish it or not, we cannot avoid hereafter having duties to do in the face of other nations. All that we can do is to settle whether we shall perform these duties well or ill."

“There is much talk about "jingoism". If by "jingoism" they mean a policy in pursuance of which Americans will with resolution and common sense insist upon our rights being respected by foreign powers, then we are "jingoes".”

“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.”

“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.”

“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.”
