"In new and wild communities where there is violence, an honest man must protect himself; and until other means of securing his safety are devised, it is both foolish and wicked to persuade him to surrender his arms while the men who are dangerous to the community retain theirs. He should not renounce the right to protect himself by his own efforts until the community is so organized that it can effectively relieve the individual of the duty of putting down violence. So it is with nations. Each nation must keep well prepared to defend itself until the establishment of some form of international police power, competent and willing to prevent violence as between nations. As things are now, such power to command peace throughout the world could best be assured by some combination between those great nations which sincerely desire peace and have no thought themselves of committing aggressions. The combination might at first be only to secure peace within certain definite limits and on certain definite conditions; but the ruler or statesman who should bring about such a combination would have earned his place in history for all time and his title to the gratitude of all mankind."

“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.”
