"There can be no effective control of corporations while their political activity remains. To put an end to it will be neither a short nor an easy task, but it can be done. We must have complete and effective publicity of corporate affairs, so that the people may know beyond peradventure whether the corporations obey the law and whether their management entitles them to the confidence of the public. It is necessary that laws should be passed to prohibit the use of corporate funds directly or indirectly for political purposes; it is still more necessary that such laws should be thoroughly enforced. Corporate expenditures for political purposes, and especially such expenditures by public-service corporations, have supplied one of the principal sources of corruption in our political affairs."

“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.”
