The passion for dealing with social questions is one of the marks of our time. Every man gets some experience of, and makes some observations on social affairs. Except matters of health, probably none have such general interest as matters of society. Except matters of health, none are so much afflicted by dogmatism and crude speculation as those which appertain to society. The amateurs in social science always ask: What shall we do? What shall we do with Neighbor A? What shall we do for Neighbor B? What shall we make Neighbor A do for Neighbor B? It is a fine thing to be planning and discussing broad and general theories of wide application. The amateurs always plan to use the individual for some constructive and inferential social purpose, or to use the society for some constructive and inferential individual purpose. For A to sit down and think, What shall I do? is commonplace; but to think what B ought to do is interesting, romantic, moral, self-flattering, and public-spirited all at once. It satisfies a great number of human weaknesses at once. To go on and plan what a whole class of people ought to do is to feel one's self a power on earth, to win a public position, to clothe one's self in dignity. Hence we have an unlimited supply of reformers, philanthropists, humanitarians, and would-be managers-in-general of society. Every man and woman in society has one big duty. That is, to take care of his or her own self. This is a social duty. For, fortunately, the matter stands so that the duty of making the best of one's self individually is not a separate thing from the duty of filling one's place in society, but the two are one, and the latter is accomplished when the former is done. The common notion, however, seems to be that one has a duty to society, as a special and separate thing, and that this duty consists in considering and deciding what other people ought to do. Now, the man who can do anything for or about anybody else than himself is fit to be head of a family; and when he becomes head of a family he has duties to his wife and his children, in addition to the former big duty. Then, again, any man who can take care of himself and his family is in a very exceptional position, if he does not find in his immediate surroundings people who need his care and have some sort of a personal claim upon him. If, now, he is able to fulfill all this, and to take care of anybody outside his family and his dependents, he must have a surplus of energy, wisdom, and moral virtue beyond what he needs for his own business. No man has this; for a family is a charge which is capable of infinite development, and no man could suffice to the full measure of duty for which a family may draw upon him. Neither can a man give to society so advantageous an employment of his services, whatever they are, in any other way as by spending them on his family. Upon this, however, I will not insist. I recur to the
