"A perfectly stupid race can never rise to a very high plane; the negro, for instance, has been kept down as much by lack of intellectual development as by anything else; but the prime factor in the preservation of a race is its power to attain a high degree of social efficiency. Love of order, ability to fight well and breed well, capacity to subordinate the interests of the individual to the interests of the community, these and similar rather humdrum qualities go to make up the sum of social efficiency. The race that has them is sure to overturn the race whose members have brilliant intellects, but who are cold and selfish and timid, who do not breed well or fight well, and who are not capable of disinterested love of the community. In other words, character is far more important than intellect to the race as to the individual. We need intellect, and there is no reason why we should not have it together with character; but if we must choose between the two we choose character without a moment's hesitation."

“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.”
