"Practical equality of opportunity for all citizens, when we achieve it, will have two great results. First, every man will have a fair chance to make of himself all that in him lies; to reach the highest point to which his capacities, unassisted by special privilege of his own and unhampered by the special privilege of others, can carry him, and to get for himself and his family substantially what he has earned. Second, equality of opportunity means that the commonwealth will get from every citizen the highest service of which he is capable. No man who carries the burden of the special privileges of another can give to the commonwealth that service to which it is fairly entitled."

“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.”
