Custom is valuable, if for nothing else, in the fact that it makes possible some accommodation or adjustment of competing individual interests—and on the basis of a widely considered social welfare. Customs are social, they are binding on all; they apply to all, and to the extent that they do promote welfare, they promote, within limits, the welfare of all. A man conforming to custom is thereby consulting something other than his arbitrary caprice or personal desire. On the level of customary morality, action through conformity to custom is referred to a wider context than unconsidered individual impulse; it is, for better or worse, performed with reference to the group with whose standards it is in conformity. It is the beginning of the socialization of human interests. Though unconsciously, the man conforming to a custom is considering his fellows, and the values and traditions which have become current among them.

Customs, moreover, are the first invasion of moral chaos. They establish enduring standards; they give common and permanent bases of action. It is only through the establishment and transmission of customary standards that one generation is in any way superior to its predecessors. Customs, in civilized life, include all the established effective ways of civilization, its arts, its sciences, its industries, and its useful modes of coöperation.

If a plague carried off the members of a society all at once, it is obvious that the group would be permanently done for. Yet the death of each of its constituent members is as certain as if a plague took them off all at once. But the graded difference in age, the fact that some are born as some die, makes possible through transmission of ideas and practices the constant reweaving of the social fabric. Yet this renewal is not automatic. Unless pains are taken to see that genuine and thorough transmission takes place, the most civilized group will relapse into barbarism and then into savagery.[1]

[Footnote 1: Dewey: Democracy and Education, p. 4.]

In all levels of civilization, there is a conscious transmission of those social habits which are regarded as of importance. If this transmission were suddenly to cease, not only would each generation have to start afresh, but it would be altogether impossible for it to grow to maturity.

The defects of customary morality. While custom is thus valuable as a moral agent in establishing standards of social life and rendering them continuous and enduring, a morality that is completely based upon it has serious defects. Though customs may start as allegedly or actually useful practices, they tend, so strong is the influence of habit over the individual, to outlive their usefulness, and may become, indeed, altogether disadvantageous conventions. "Dr. Arthur Smith tells of the advantage it would be in some parts of China to build a door on the south side of the house, in order to get the breeze, in hot weather." The simple and sufficient answer to such a suggestion is, "We don't build doors on the south side."

We have but to examine our own civilization to see that there are many customs which are practiced not for any good assignable reason, but simply because they have become fixed and traditional. This is not to say that everything that has become "merely conventional" is evil. It is to suggest how, even in civilized society, groups may fall into modes of action that are practiced simply because they have been practiced, rather than from any reasoned consideration that they should be. An illustration may be taken from the experience of civilians drawn into the military routine during the Great War. Men engaged in war work at Washington in civilian capacities reported repeatedly their impatience at the "red tape" of tradition with which certain classes of business were conducted by the military establishment. In law also, progressive practitioners and students have pointed out the well-known fact of the immense and beclogging ritual which has come to surround legal procedure. It is the contention of critics of one or another of our contemporary social habits and institutions that traditionalism, the persistence of custom simply because it is custom, is responsible for many of the anachronisms in our social, political, and industrial life. Space does not permit here a detailed consideration of this question, but it must be noted that social habits, when they are acquired, as they are, unreflectively by the vast majority of people, will tend to be repeated and supported, apart from any consideration of their consequences. This tendency toward social inertia, earlier noted in connection with habit, can only be checked by reflective criticism and appraisement of our current accustomed ways of action.[1]

In the case of the group, too complete a domination by custom is dangerous in that it sanctions and promotes the continuance of habits that have become useless or harmful. In the case of the individual, the determination of action by custom alone has its specific dangers and defects. Even though the individual happens to conform to useful customs, his conformity is purely mechanical. It involves no intelligent discrimination. Merely to conform places one at the disposition of the environment in which one chances to be. There is not necessary any intelligent analysis on the part of the agent, of the bearings and consequences of his actions. He takes on with fatal facility the color of his environment. To all men, however critical and reflective, a certain degree of conformity to custom is both necessary and useful. There must, in any social enterprise, be some common basis of action. Because taking the right-hand side of the road is a convention, it is none the less a useful one. But reflective acquiescence in a custom differs from merely mechanical conformity. It transforms a custom from a blind mechanism into a consciously chosen instrument for achieving good.

The trivial and the important in a morality based upon custom receive the same unconsidered support. "Tithing mint, anise, and cummin are quite likely to involve the neglect of weightier matters of the law." Physical, emotional, and moral energies that should be devoted to matters genuinely affecting human welfare are lavished upon the trivial and the incidental. We may come to be concerned more with manners than with morals; with ritual, than with right. Customary morality tends to emphasize, moreover, the letter rather than the spirit of the law. It implies complete and punctilious obedience, meticulous conformity. It emphasizes form rather than content. Since conformity is the only criterion, the appearance of conformity is all that is required. The individual may fear to dissent openly rather than actually. This is seen frequently in the ritualistic performance or fulfillment of a duty in all its external details, rather than the actual and positive performance of its content. It is just such Pharisaism that is protested against in the Sermon on the Mount:
