Public opinion, in respect to the manner in which it is formed and the manner in which it exists—that is to say relatively independent of the individuals who co-operate to form it—has the characteristics of collective representation in general. Collective representations are objective, in just the sense that public opinion is objective, and they impose themselves upon the individual as public opinion does, as relatively but not wholly external forces—stabilizing, standardizing, conventionalizing, as well as stimulating, extending, and generalizing individual representations, percepts.

The collective representations are exterior to the individual consciousness because they are not derived from the individuals taken in isolation but from their convergence and union (concours).... Doubtless, in the elaboration of the common result, each (individual) bears his due share; but the private sentiments do not become social except by combining under the action of the forces sui generis which association develops. As a result of these combinations, and of the mutual alterations which result therefrom, they (the private sentiments) become something else (autre chose). A chemical synthesis results, which concentrates, unifies, the elements synthetized, and by that very process transforms them.... The resultant derived therefrom extends then beyond (deborde) the individual mind as the whole is greater than the part. To know really what it is, one must take the aggregate in its totality. It is this that thinks, that feels, that wills, although it may not be able to will, feel, or act save by the intermediation of individual consciousnesses.[41]

This, then, after nearly a century of criticism, is what remains of Comte's conception of the social organism. If society is, as the realists insist, anything more than a collection of like-minded individuals, it is so because of the existence (1) of a social process and (2) of a body of tradition and opinion—the products of this process—which has a relatively objective character and imposes itself upon the individual as a form of control, social control. This process and its product are the social consciousness. The social consciousness, in its double aspect as process and product, is the social organism. The controversy between the realists and the nominalists reduces itself apparently to this question of the objectivity of social tradition and of public opinion. For the present we may let it rest there.

Meanwhile the conceptions of the social consciousness and the social mind have been adopted by writers on social topics who are not at all concerned with their philosophical implications or legitimacy. We are just now seeing the first manifestations of two new types of sociology which call themselves, the one rural and the other urban sociology. Writers belonging to these two schools are making studies of what they call the "rural" and the "urban" minds. In using these terms they are not always quite certain whether the mind of which they are thinking is a collective mind, in Durkheim's realistic sense of the word, or whether it is the mind of the typical inhabitant of a rural or an urban community, an instance of "like-mindedness," in the sense of Giddings and the nominalists.

A similar usage of the word "mind," "the American mind," for example, is common in describing characteristic differences in the attitudes of different nations and their "nationals."

The origin of the phrase, "the American mind," was political. Shortly after the middle of the eighteenth century, there began to be a distinctly American way of regarding the debatable question of British Imperial control. During the period of the Stamp Act agitation our colonial-bred politicians and statesmen made the discovery that there was a mode of thinking and feeling which was native—or had by that time become a second nature—to all the colonists. Jefferson, for example, employs those resonant and useful words "the American mind" to indicate that throughout the American colonies an essential unity of opinion had been developed as regards the chief political question of the day.[42]

Here again, it is not quite clear, whether the American mind is a name for a characteristic uniformity in the minds of individual Americans; whether the phrase refers rather to an "essential unity of opinion," or whether, finally, it is intended to cover both the uniformity and the unity characteristic of American opinion.

Students of labor problems and of the so-called class struggle, on the other hand, use the term "psychology" in much the same way that the students of rural and urban sociology use the term "mind." They speak of the "psychology" of the laboring class, the "psychology" of the capitalistic class, in cases where psychology seems to refer indifferently either to the social attitudes of the members of a class, or to attitude and morale of the class as a whole.

The terms "class-conscious" and "class-consciousness," "national" and "racial" consciousness are now familiar terms to students although they seem to have been used, first of all, by the so-called "intelligentsia", who have been the leaders in the various types of mass movement to which these terms apply. "Consciousness," in the sense in which it is here used, has a similar, though somewhat different, connotation than the word "mind" when applied to a group. It is a name not merely for the attitudes characteristic of certain races or classes, but for these attitudes when they are in the focus of attention of the group, in the "fore-consciousness" to use a Freudian term. In this sense "conscious" suggests not merely the submergence of the individual and the consequent solidarity of the group, but it signifies a mental mobilization and preparedness of the individual and of the group for collective or corporate action. To be class-conscious is to be prepared to act in the sense of that class.

There is implicit in this rather ambiguous popular usage of the terms "social mind" and "social consciousness" a recognition of the dual aspect of society and of social groups. Society may be regarded at the same time from an individualistic and a collectivistic point of view. Looking at it from the point of view of the individual, we regard as social just that character of the individual which has been imparted to, and impressed upon, him as a result of his participation in the life of the group. Social psychology, from Baldwin's first studies of the development of personality in the child to Ellwood's studies of the society in its "psychological aspects" has been mainly concerned with the investigation of the effects upon the individual of his contacts with other individuals.[43]
