"If I could ask but one thing of my fellow countrymen, my request would be that, whenever they go in for reform, they remember the two sides, and that they always exact justice from one side as much as from the other. I have small use for the public servant who can always see and denounce the corruption of the capitalist, but who cannot persuade himself, especially before election, to say a word about lawless mob-violence. And I have equally small use for the man, be he a judge on the bench or editor of a great paper, or wealthy and influential private citizen, who can see clearly enough and denounce the lawlessness of mob-violence, but whose eyes are closed so that he is blind when the question is one of corruption of business on a gigantic scale. Also, remember what I said about excess in reformer and reactionary alike. If the reactionary man, who thinks of nothing but the rights of property, could have his way, he would bring about a revolution; and one of my chief fears in connection with progress comes because I do not want to see our people, for lack of proper leadership, compelled to follow men whose intentions are excellent, but whose eyes are a little too wild to make it really safe to trust them."

“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.”
