"In every wise struggle for human betterment one of the main objects, and often the only object, has been to achieve in large measure equality of opportunity. In the struggle for this great end, nations rise from barbarism to civilization, and through it people press forward from one stage of enlightenment to the next. One of the chief factors in progress is the destruction of special privilege. The essence of any struggle for healthy liberty has always been, and must always be, to take from some one man or class of men the right to enjoy power, or wealth, or position, or immunity, which has not been earned by service to his or their fellows. That is what you fought for in the Civil War, and that is what we strive for now."

“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.”
