"Justice and fair dealings among nations rest upon principles identical with those which control justice and fair dealing among the individuals of which nations are composed, with the vital exception that each nation must do its own part in international police work. If you get into trouble here, you can call for the police; but if Uncle Sam gets into trouble, he has got to be his own policeman, and I want to see him strong enough to encourage the peaceful aspirations of other people's in connection with us. I believe in national friendships and heartiest good-will to all nations; but national friendships, like those between men, must be founded on respect as well as on liking, on forbearance as well as upon trust. I should be heartily ashamed of any American who did not try to make the American government act as justly toward the other nations in international relations as he himself would act toward any individual in private relations. I should be heartily ashamed to see us wrong a weaker power, and I should hang my head forever if we tamely suffered wrong from a stronger power."

“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.”
