observation that a man who proposes to take care of other people must have himself and his family taken care of, after some sort of a fashion, and must have an as yet unexhausted store of energy. The danger of minding other people's business is twofold. First, there is the danger that a man may leave his own business unattended to; and, second, there is the danger of an impertinent interference with another's affairs. The "friends of humanity" almost always run into both dangers. I am one of humanity, and I do not want any volunteer friends. I regard friendship as mutual, and I want to have my say about it. I suppose that other components of humanity feel in the same way about it. If so, they must regard any one who assumes the _role_ of a friend of humanity as impertinent. The reference to the friend of humanity back to his own business is obviously the next step. Yet we are constantly annoyed, and the legislatures are kept constantly busy, by the people who have made up their minds that it is wise and conducive to happiness to live in a certain way, and who want to compel everybody else to live in their way. Some people have decided to spend Sunday in a certain way, and they want laws passed to make other people spend Sunday in the same way. Some people have resolved to be teetotalers, and they want a law passed to make everybody else a teetotaler. Some people have resolved to eschew luxury, and they want taxes laid to make others eschew luxury. The taxing power is especially something after which the reformer's finger always itches. Sometimes there is an element of self-interest in the proposed reformation, as when a publisher wanted a duty imposed on books, to keep Americans from reading books which would unsettle their Americanisms; and when artists wanted a tax laid on pictures, to save Americans from buying bad paintings. I make no reference here to the giving and taking of counsel and aid between man and man: of that I shall say something in the last chapter. The very sacredness of the relation in which two men stand to one another when one of them rescues the other from vice separates that relation from any connection with the work of the social busybody, the professional philanthropist, and the empirical legislator. The amateur social doctors are like the amateur physicians--they always begin with the question of _remedies_, and they go at this without any diagnosis or any knowledge of the anatomy or physiology of society. They never have any doubt of the efficacy of their remedies. They never take account of any ulterior effects which may be apprehended from the remedy itself. It generally troubles them not a whit that their remedy implies a complete reconstruction of society, or even a reconstitution of human nature. Against all such social quackery the obvious injunction to the quacks is, to mind their own business.
