Most of the voluntary associations of our modern life are of a character chiefly impersonal; that is they tend to a specialization by which one interest of the individual is allied with the similar interests of others, leaving his personality as a whole outside the group. The ordinary active citizen of our day joins a dozen or more organizations, for profit, for culture, for philanthropy, or what-not, into each of which he puts only a fragment of himself, and for which he feels no serious responsibility. It is very commonly the case, however, that one or a few individuals—zealous employees or unpaid enthusiasts for the cause—do identify themselves with the life of the association and put personality into it. And this may happen with those social growths which we have noticed as peculiarly impersonal—even with language, as when an enthusiast sets out to revive Irish or promote Volapük.

May we not say, indeed, that whenever two persons associate we have a new whole whose life cannot altogether be understood by regarding it merely as the sum of the two? This is clearly the case with husband and wife, and no doubt, in measure, with other relations.

If we inquire more closely into the interaction and growth of these forms of life we come upon what I will call the tentative process. This is no other than what is vaguely known to popular thought as the process of evolutionary “selection,” or the survival of the fittest, and is also described as the method of trial and error, the pragmatic method, the growth of that which “works” or functions, and by other terms similar to these. Perhaps as simple a description as any is to say that it is a process of experiment which is not necessarily conscious. That is, the trial of various activities and the guidance of behavior by the result of the trial may require no understanding of what is taking place.

The growth of social forms is for the most part roughly analogous to that of the wild-grape vine which has extended itself over trellises and fences and into trees in my back yard. This vine has received from its ancestry a certain system of tendencies. There is, for example, the vital impulse itself, the general bent to grow. Then there is its habit of sending out straight, rapidly growing shoots with two-branched tendrils at the end. These tendrils revolve slowly through the air, and when one touches an obstacle, as a wire or branch, it hooks itself about it and draws up in the form of a spiral spring, pulling the shoot up after it. A shoot which thus gets a hold grows rapidly and sends out more tendrils; if it fails to get a hold it by and by sags down and ceases to grow. Thus it feels its way and has a system of behavior which insures its growth along the line of successful experiment.

So in the human world we find that forms of life tending to act in certain ways come into contact with situations which stimulate some of their activities and repress others. Those that are stimulated increase, this increase acts upon the structures involved in it—usually to augment their growth—and so a “selective” development is set in motion. Intelligence may have a part in this or it may not; nothing is essential but active tendencies and conditions which guide their operation.

You may sometimes see one vine growing upon another, involving the mutual adaptation of two living forms. In human life this is the usual condition, the environment being not something fixed but another plastic organism, interacting in turn with still other organisms, giving rise to an endless system of reciprocal growth. One form of life feels about among the various openings or stimuli offered by another, and responds to those which are most congruous with its own tendencies. The two experiment with each other and discover and develop some way, more or less congenial, of getting along. This is evidently true of persons, and the principle applies equally to groups, ideas, and institutions.

We have, at any given moment, a complex of personal and impersonal wholes each of which is charged with energy and tendency in the form of heredity and habit coming from its past. If we fix our attention upon any particular whole—a person, a party, a state, a doctrine, a programme of reform, a myth, a language—we shall find it in the act of making its way, of growing if it can, in the direction of its tendencies. As we have seen, it is alive, however impersonal, and has human flesh, blood, and nerves to urge it on. It already has adapted structure—hands and feet as Luther said of the Word of God—because if it had not developed something of the sort, some fitness to live in the general stream of human life, we should not in fact find it there. As its means of further growth it has a repertory of available activities; and these, consciously or otherwise, are tried upon the situation. If not guided by something in the nature of intelligence they act blindly, and may nevertheless act effectively. In general some one or some combination of these activities will work better in the situation than others, finding more scope or stimulus of some sort, and will grow accordingly; the energies of the whole, so far as they are available, tending to find an outlet at this point. Thus the more a thing works the more it is enabled to work, since the fact that it functions draws more and more energy to it. And the whole to which it belongs, in thus continuing and enhancing the successful activity, behaves very much as if it were conducting a deliberate experiment. The enhanced activity also involves changes in the whole and in the situation at large; and thus we move on to new situations and new operations of the same principle.

Take, for illustration, the growth of a man at any point of his career; let us say a youth starting out to make his living. He has energies and capacities of which he is for the most part but vaguely aware. Young people wave their instincts and habits about for something to catch on very much as a vine does its tendrils. Suggestions as to possible lines of work, drawn from what he sees about him, are presented to his mind and, considering these with such light as he may have, he seeks a job. He selects as among his opportunities, and at the same time his opportunities, in the form of possible employers, select as between him and other seekers. Having undertaken a job he may find that he cannot do the work, or that it is too repugnant to his inclinations, in which case he presently drops it and tries another. But if he succeeds and likes it his energy more and more flows into it, his whole mind is directed toward it, he grows in that sense. And his success usually secures to him a larger and larger part to play in his chosen field, thus opening new opportunities for growth in the same direction. Life is constantly revealing openings which we could not have anticipated. It is like paddling toward the outlet of a lake, which you cannot locate until you are almost in it. We think that our course must extend in one of two directions; but further advance shows that there is a third more practicable than either. A little idea that we have overlooked or deemed insignificant often grows until it renders obsolete those we thought great.

In the case of a group under personal leadership the process is not greatly different. A political party, a business enterprise, a social settlement, a church, a nation, develops by means of a mixture of foresight and unforeseen experience. It feels its way, more or less intelligently, until it finds an opening, in the form of policies that prove popular, unexploited markets, neglected wrongs, more timely doctrines, or the like; and then, through increased activity at the point of success, develops in the propitious direction.

Fashion well illustrates the tentative growth of an impersonal form. Thus fashions in women’s dress are initiated, it appears, at Paris, this city having a great prestige in the matter which it has achieved by some centuries of successful leadership. In Paris there are a large number of professional designers of dress who are constantly endeavoring to foresee the course of change, and to produce designs that will “take.” They compete with one another in this, and those who succeed gain wealth and reputation for themselves and the commercial establishments with which they are connected. Although they initiate they by no means have the power to do this arbitrarily, but have to adapt themselves to vague but potent tendencies in the mind of their public. It is their business to divine these and to produce something which will fit the psychological situation. At the seasons when new styles are looked for the rival artists are ready with their designs, which they try upon the public by causing professional models, actresses, or other notabilities to appear in them. Of the many so presented only a few come into vogue, and no designer can be certain of success: no one can surely foresee what will work and what will not. But the designs that win in Paris spread almost without opposition over the rest of the fashionable earth.
