The Origin of Society.—From the definition of society that we have given it is evident that society is something which springs from the very processes of life itself. It is not something which has been invented or planned by individuals. Life, in its higher forms at least, could not exist without association. From the very beginning the association of the sexes has been necessary for reproduction and for the care and rearing of offspring, and it has been not less necessary for the procuring of an adequate food supply and for protection against enemies. From the association necessary for reproduction has sprung family life and all the altruistic institutions of human society, while from the association for providing food supply have sprung society's industrial institutions. Neither society nor industry, therefore, has had a premeditated, reflective origin, but both have sprung up spontaneously from the needs of life and both have developed down to the present time at least with but little premeditated guidance. It is necessary that the student should understand at the outset that social organization is not a fabrication of the human intellect to any great degree, and the old idea that individuals who existed independently of society came together and deliberately planned a certain type of social organization is utterly without scientific validity. The individual and society are correlatives. We have no knowledge of individuals apart from society or society apart from individuals. What we do know is that human life everywhere is a collective or associated life, the individual being on the one hand largely an expression of the social life surrounding him and on the other hand society being largely an expression of individual character. The reasons for these assertions will appear later as we develop our subject.
What is Sociology?—The science which deals with human association, its origin, development, forms, and functions, is sociology. Briefly, sociology is a science which deals with society as a whole and not with its separate aspects or phases. It attempts to formulate the laws or principles which govern social organization and social evolution. This means that the main problems of sociology are those of the organization of society on the one hand and the evolution of society on the other. These words, organization and evolution, however, are used in a broader sense in sociology than they are generally used. By organization we mean any relation of the parts of society to each other. By evolution we mean, not necessarily change for the better, but orderly change of any sort. Sociology is, therefore, a science which deals with the laws or principles of social organization and of social change. Put in more exact terms this makes sociology, as we said at the beginning, the science of the origin, development, structure, and function of the forms of association. We may pass over very rapidly certain faulty conceptions of sociology. The first of these is that it is the study of social evils and their remedies. This conception is faulty because it makes sociology deal primarily with the abnormal rather than the normal conditions in society, and secondly, it is to be criticized because it makes sociology synonymous with scientific philanthropy. It is rather the science of philanthropy, which is an applied science resting upon sociology, that studies social evils and their remedies. This is not saying, of course, that sociology does not consider social evils, but that it considers them as incidents in the normal processes of social evolution rather than as its special matter. A second conception of sociology which is to be dismissed as inadequate is the conception that it is the science of social phenomena. This conception is not incorrect, but is somewhat vague, as there are manifestly other sciences of social phenomena, such as economics and political science. Such a conception of sociology would make it include everything in human society. A third faulty conception is that it is the science of human institutions. This is faulty because it again is too narrow. An institution is a sanctioned form of human association, while sociology deals with the ephemeral and unsanctioned forms, such as we see in the phenomena of mobs, crazes, fads, fashions, and crimes, as well as with the sanctioned forms. A fourth conception which might be criticized is that sociology is the science of social organization. This makes sociology deal with the laws or principles of the relations of individuals to one another, and of institutions to one another. It is to be criticized as faulty because it fails to emphasize the evolution of those relations. All science is now evolutionary in spirit and in method and believes that things cannot be understood except as they are understood in their genesis and development. It would, therefore, perhaps be more correct to define sociology as the science of the evolution of human interrelations than to define it simply as the science of social organization.
The Problems of Sociology.—The problems of sociology fall into two great classes; first, problems of the organization of society, and second, problems of the evolution of society. The problems of the organization of society are problems of the relations of individuals to one another and to institutions. Such problems are, for example, the influence of various elements in the physical environment upon the social organization; or, again, the influence of various elements in human nature upon the social order. These problems are, then, problems of society in a hypothetically stationary condition or at rest. For this reason Comte, the founder of modern sociology, called the division of sociology which deals with such problems Social Statics. But the problems which are of most interest and importance in sociology are those of social evolution. Under this head we have the problem of the origin of society in general and also of various forms of association. More important still are the problems of social progress and social retrogression; that is, the causes of the advancement of society to higher and more complex types of social organization and the causes of social decline. The former problem, social progress, is in a peculiar sense the central problem of sociology. The effort of theoretical sociology is to develop a scientific theory of social progress. The study of social evolution, then, that is, social changes of all sorts, as we have emphasized above, is the vital part of sociology; and it is manifest that only a general science of society like sociology is competent to deal with such a problem. Inasmuch as the problems of social evolution are problems of change, development, or movement in society, Comte proposed that this division of sociology be called Social Dynamics.
The Relations of Sociology to Other Sciences. [Footnote: For a fuller discussion of the relations of sociology to other sciences and to philosophy see my article on "Sociology: Its Problems and Its Relations" in the American Journal of Sociology for November, 1907.]—(A) Relations to Biology and Psychology. In attempting to give a scientific view of social organization and social evolution, sociology has to depend upon the other natural sciences, particularly upon biology and psychology. It is manifest that sociology must depend upon biology, since biology is the general science of life, and human society is but part of the world of life in general. It is manifest also that sociology must depend upon psychology to explain the interactions between individuals because these interactions are for the most part interactions between their minds. Thus on the one hand all social phenomena are vital phenomena and on the other hand nearly all social phenomena are mental phenomena. Every social problem has, in other words, its psychological and its biological sides, and sociology is distinguished from biology and psychology only as a matter of convenience. The scientific division of labor necessitates that certain scientific workers concern themselves with certain problems. Now, the problems with which the biologist and the psychologist deal are not the problems of the organization and evolution of society. Hence, while the sociologist borrows his principles of interpretation from biology and psychology, he has his own distinctive problems, and it is this fact which makes sociology a distinct science.
Sociology is not so easily distinguished from the special social sciences like politics, economics, and others, as it is from the other general sciences. These sciences occupy the same field as sociology, that is, they have to do with social phenomena. But in general, as has already been pointed out, they are concerned chiefly with certain very special aspects or phases of the social life and not with its most general problems. If sociology, then, is dependent upon the other general sciences, particularly upon biology and psychology, it is obvious that its relation to the special sciences is the reverse, namely, these sciences are dependent upon sociology. This is only saying practically the same thing as was said above when we pointed out that industry, government, and religion are but expressions of human social life. In other words, sociology deals with the more general biological and psychological aspects of human association, while the special sciences of economics, politics, and the like, generally deal with certain products or highly specialized phases of society.
(B) Relations to History. [Footnote: For a discussion of the practical relations between the teaching of history and of sociology, see my paper on "How History can be taught from a Sociological Point of View," in Education for January, 1910.] A word may be said about the relation of sociology to another science which also deals with human society in a general way, and that is history. History is a concrete, descriptive science of society which attempts to construct a picture of the social past. Sociology, however, is an abstract, theoretical science of society concerned with the laws and principles which govern social organization and social change. In a sense, sociology is narrower than history inasmuch as it is an abstract science, and in another sense it is wider than history because it concerns itself not only with the social past but also with the social present. The facts of contemporary social life are indeed even more important to the sociologist than the facts of history, although it is impossible to construct a theory of social evolution without taking into full account all the facts available in human history, and in this sense history becomes one of the very important methods of sociology. Upon its evolutionary or dynamic side sociology may be considered a sort of philosophy of history; at least it attempts to give a scientific theory which will explain the social changes which history describes concretely.
(C) Relations to Economics. Economics is that special social science which deals with the wealth-getting and wealth-using activities of man. In other words, it is concerned with the commercial and industrial activities of man. As has already been implied, economics must be considered one of the most important of the special social sciences, if not the most important. Yet it is evident that the wealth-getting and wealth-using activities of man are strictly an outgrowth of his social life, and that economics as a science of human industry must rest upon sociology. Sometimes in the past the mistake has been made of supposing that economics dealt with the most fundamental social phenomena, and even at times economists have spoken of their science as alone sufficient to explain all social phenomena. It cannot be admitted, however, that we can explain social organization in general or social progress in terms of economic development. A theory of progress, for example, in which the sole causes of human progress were found in economic conditions would neglect political, religious, educational, and many other conditions. Only a very one-sided theory of society can be built upon such a basis. Economics should keep to its own sphere of explaining the commercial and industrial activities of man and not attempt to become a general science dealing with social evolution. This is now recognized by practically all economists of standing, and the only question which remains is whether economics is independent of sociology or whether it rests upon sociology.
The view which has been presented thus far and which will be adhered to is that economics should rest upon sociology. That economics does rest upon sociology is shown by many considerations. The chief problem of theoretical economics is the problem of economic value. But economic value is but one sort of value which is recognized in society, moral and aesthetic values being other examples of the valuing process, and all values must express the collective judgment of some human group or other. The problem of economic value, in other words, reduces itself to a problem in social psychology, and when this is said it is equivalent to making economics dependent upon sociology, for social psychology is simply the psychological aspect of sociology. Again, industrial organization and industrial evolution are but parts or phases of social evolution in general, and it is safe to say that industry, both in its organization and evolution, cannot be understood apart from the general conditions, psychological and biological, which surround society. Again, many non-economic forces continually obtrude themselves upon the student of industrial conditions, such as custom, invention, imitation, standards, ideals, and the like. These are general social forces which play throughout all phases of human social life and so show the dependence of industry upon society in general, and, therefore, of economics upon sociology. Much more might be said in the way of concretely illustrating these statements, but the purpose of this text precludes anything but the briefest and most elementary statement of these theoretical facts.
(D) Relations to Politics. We have already said that the state is one of the chief forms of human association. The science which treats of the state or of government is known as political science or politics. It is one of the oldest of the social sciences, having been more or less systematized by Aristotle. The problems of politics are those of the origin, nature, function, and development of government. It is manifest that politics, both on its practical and theoretical sides, has many close relations to sociology. While the state or nation must not be confused with society in general, yet because the state is the most imposing, if not the most important, form of human association, the relations of politics and sociology must be very intimate. On the one hand, political scientists can scarcely understand the origin, nature, and proper functions of government without understanding more or less about the social life generally; and, on the other hand, the sociologist finds that one of the most important facts of human society is that of social control, or of authority. While political science deals only with the organized authority manifested in the state, which we call government, yet inasmuch as this is the most important form of social control, and inasmuch as political organization is one of the chief manifestations of social organization, the sociologist can scarcely deal adequately with the great problems of social organization and evolution without constant reference to political science.
An important branch of political science is jurisprudence, or the science of law. This, again, is closely related with sociology, on both its theoretical and practical sides. Law is, perhaps, the most important means of social control made use of by society, and the sociologist needs to understand something of the principles of law in order to understand the nature of the existing social order. On the other hand, the jurist needs to know the principles of social organization and evolution in general before he can understand the nature and purpose of law.
