"The welfare of each of us is dependent fundamentally upon the welfare of all of us, and therefore in public life that man is the best representative of each of us who seeks to do good to each by doing good to all; in other words, whose endeavor it is not to represent any special class and promote merely that class's selfish interests, but to represent all true and honest men of all sections and all classes and to work for their interests by working for our common country. We can keep our government on a sane and healthy basis, we can make and keep our social system what it should be, only on condition of judging each man, not as a member of a class, but on his worth as a man. It is an infamous thing in our American life, and fundamentally treacherous to our institutions, to apply to any man any test save that of his personal worth, or to draw between two sets of men any distinction save the distinction of conduct, the distinction that marks off those who do well and wisely from those who do ill and foolishly."

“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.”

“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.”
