Professor Cooley stresses the unconscious character of many of these social relations. "Although the growth of social consciousness is perhaps the greatest fact of history, it has still but a narrow and fallible grasp of human life." Cooley objects to the Cartesian postulate, which makes "_cogito_," "I think," the fundamental and most absolutely certain fact in the world. He holds that it grows out of the idiosyncrasy of a highly specialized, introspective philosopher's mind, and that, for the normal mind, "_cogitamus_," "we think," is just as obvious.[113] The "I" feeling, and the "we" feeling are differentiated together out of the inchoate experience of the child. And "I" and "we" are alike social in their nature. The self, for Professor Cooley, is not a scholastic "soul-substance" or transcendental ego, but simply a relatively differentiated portion of the social mind. "'Social organism' using the term in no abstruse sense, but merely to mean a vital unity in human life, is a fact as obvious to enlightened common sense as individuality."[114]
I pause here to contrast this view of the "social mind" with that of some other writers, of whom I may take Professor Giddings as representative. I quote from page 134 of the 1905 edition of Professor Giddings' _Principles of Sociology_:--
The social mind is the phenomenon of many individual minds in interaction, so playing upon one another that they simultaneously feel the same sensation or emotion, arrive at one judgment and perhaps act in concert. It is, in short, the mental unity of many individuals, or of a crowd.
The social mind for Professor Giddings is thus made to depend upon an _identity of content_ in many individual minds. For Professor Cooley, it is an organization and integration of many differentiated and divergent minds, in a complementary activity. Professor Cooley's conception, thus, takes in all minds, while that of Professor Giddings would exclude the dissenters. Further, Professor Giddings emphasizes the element of consciousness; unconscious processes are included by Professor Cooley, whose conception really finds a place for the total psychosis of every individual in society. It may be noted, however, that Professor Giddings, in the more detailed exposition of the classroom, does not stress either the agreement or the consciousness in the absolute fashion that the brief passage quoted would indicate, and readily concedes that for theoretical purposes the more inclusive conception of Professor Cooley's is a very useful one. The difference between his viewpoint, as set forth in the classroom, and that of Professor Cooley, is primarily a matter of emphasis.[115]
