"We have come to recognize that franchises should never be granted except for a limited time, and never without proper provision for compensation to the public. It is my personal belief that the same kind and degree of control and supervision which should be exercised over public-service corporations should be extended also to combinations which control necessaries of life, such as meat, oil, or coal, or which deal in them on an important scale. I have no doubt that the ordinary man who has control of them is much like ourselves. I have no doubt he would like to do well, but I want to have enough supervision to help him realize that desire to do well. I believe that the officers, and, especially, the directors, of corporations should be held personally responsible when any corporation breaks the law."

“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.”
