"The first essential in determining how to deal with the great industrial combinations is knowledge of the facts—publicity. In the interest of the public, the Government should have the right to inspect and examine the workings of the great corporations engaged in interstate business. Publicity is the only sure remedy which we can now invoke. What further remedies are needed in the way of governmental regulation, or taxation, can only be determined after publicity has been obtained, by process of law, and in the course of administration. The first requisite is knowledge, full and complete—knowledge which may be made public to the world. Artificial bodies, such as corporations and joint stock or other associations, depending upon any statutory law for their existence or privileges, should be subject to proper governmental supervision, and full and accurate information as to their operations should be made public regularly at reasonable intervals."

“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.”
