A. PHYSICAL CONTACT AND SOCIAL CONTACT
1. The Frontiers of Social Contact[121]
Sociology deals especially with the phenomena of contact. The reactions which result from voluntary or involuntary contact of human beings with other human beings are the phenomena peculiarly "social," as distinguished from the phenomena that belong properly to biology and psychology.
In the first place, we want to indicate, not the essence of the social, but the location, the sphere, the extent, of the social. If we can agree where it is, we may then proceed to discover what it is. The social, then, is the term next beyond the individual. Assuming, for the sake of analysis, that our optical illusion, "the individual," is an isolated and self-sufficient fact, there are many sorts of scientific problems that do not need to go beyond this fact to satisfy their particular terms. Whether the individual can ever be abstracted from his conditions and remain himself is not a question that we need here discuss. At all events, the individual known to our experience is not isolated. He is connected in various ways with one or more individuals. The different ways in which individuals are connected with each other are indicated by the inclusive term "contact." Starting, then, from the individual, to measure him in all his dimensions and to represent him in all his phases, we find that each person is what he is by virtue of the existence of other persons, and by virtue of an alternating current of influence between each person and all the other persons previously or at the same time in existence. The last native of Central Africa around whom we throw the dragnet of civilization, and whom we inoculate with a desire for whiskey, adds an increment to the demand for our distillery products, and affects the internal revenue of the United States, and so the life-conditions of every member of our population. This is what we mean by "contact." So long as that African tribe is unknown to the outside world, and the world to it, so far as the European world is concerned, the tribe might as well not exist. The moment the tribe comes within touch of the rest of the world, the aggregate of the world's contacts is by so much enlarged; the social world is by so much extended. In other words, the realm of the social is the realm of circuits of reciprocal influence between individuals and the groups which individuals compose. The general term "contact" is proposed to stand for this realm, because it is a colorless word that may mark boundaries without prejudging contents. Wherever there is physical or spiritual contact between persons, there is inevitably a circuit of exchange of influence. The realm of the social is the realm constituted by such exchange. It extends from the producing of the baby by the mother, and the simultaneous producing of the mother by the baby, to the producing of merchant and soldier by the world-powers, and the producing of the world-powers by merchant and soldier.
The most general and inclusive way in which to designate all the phenomena that sociology proper considers, without importing into the term premature hypotheses by way of explanation, is to assert that they are the phenomena of "contact" between persons.
In accordance with what was said about the division of labor between psychology and sociology, it seems best to leave to the psychologist all that goes on inside the individual and to say that the work of the sociologist begins with the things that take place between individuals. This principle of division is not one that can be maintained absolutely, any more than we can hold absolutely to any other abstract classification of real actions. It serves, however, certain rough uses. Our work as students of society begins in earnest when the individual has become equipped with his individuality. This stage of human growth is both cause and effect of the life of human beings side by side in greater or lesser numbers. Under those circumstances individuals are produced; they act as individuals; by their action as individuals they produce a certain type of society; that type reacts on the individuals and helps to transform them into different types of individuals, who in turn produce a modified type of society; and so the rhythm goes on forever. Now the medium through which all this occurs is the fact of contacts, either physical or spiritual. In either case, contacts are collisions of interests in the individuals.
2. The Land and the People[122]
Every clan, tribe, state, or nation includes two ideas, a people and its land, the first unthinkable without the other. History, sociology, ethnology, touch only the inhabited areas of the earth. These areas gain their final significance because of the people who occupy them; their local conditions of climate, soil, natural resources, physical features, and geographic situation are important primarily as factors in the development of actual or possible inhabitants. A land is fully comprehended only when studied in the light of its influence upon its people, and a people cannot be understood apart from the field of its activities. More than this, human activities are fully intelligible only in relation to the various geographic conditions which have stimulated them in different parts of the world. The principles of the evolution of navigation, of agriculture, of trade, as also the theory of population, can never reach their correct and final statement, unless the data for the conclusions are drawn from every part of the world and each fact interpreted in the light of the local conditions whence it sprang. Therefore anthropology, sociology, and history should be permeated by geography.
Most systems of sociology treat man as if he were in some way detached from the earth's surface; they ignore the land basis of society. The anthropogeographer recognizes the various social forces, economic and psychologic, which sociologists regard as the cement of societies; but he has something to add. He sees in the land occupied by a primitive tribe or a highly organized state the underlying material bond holding society together, the ultimate basis of their fundamental social activities, which are therefore derivatives from the land. He sees the common territory exercising an integrating force—weak in primitive communities where the group has established only a few slight and temporary relations with its soil, so that this low social complex breaks up readily like its organic counterpart, the low animal organism found in an amœba; he sees it growing stronger with every advance in civilization involving more complex relations to the land—with settled habitations, with increased density of population, with a discriminating and highly differentiated use of the soil, with the exploitation of mineral resources, and, finally, with that far-reaching exchange of commodities and ideas which means the establishment of varied extra-territorial relations. Finally, the modern society or state has grown into every foot of its own soil, exploited its every geographic advantage, utilized its geographic location to enrich itself by international trade, and, when possible, to absorb outlying territories by means of colonies. The broader this geographic base, the richer, more varied, its resources, and the more favorable its climate to their exploitation, the more numerous and complex are the connections which the members of a social group can establish with it, and through it with each other; or, in other words, the greater may be its ultimate historical significance.
