On the other hand, a corporeally existent person is not socially real unless he is imagined. If the nobleman thinks of the serf as a mere animal and does not attribute to him a human way of thinking and feeling the latter is not real to him in the sense of acting personally upon his mind and conscience. And if a man should go into a strange country and hide himself so completely that no one knew he was there, he would evidently have no social existence for the inhabitants. In saying this I hope I do not seem to question the independent reality of persons or to confuse it with personal ideas. The man is one thing and the various ideas entertained about him are another; but the latter, the personal idea, is the immediate social reality, the thing in which men exist for one another, and work directly upon one another’s lives. Thus any study of society that is not supported by a firm grasp of personal ideas is empty and dead—mere doctrine and not knowledge at all. I believe that the vaguely material notion of personality, which does not confront the social fact at all but assumes it to be the analogue of the physical fact, is a main source of fallacious thinking about ethics, politics, and indeed every aspect of social and personal life. It seems to underlie all four of the ways of conceiving society and the individual alleged in the first chapter to be false. If the person is thought of primarily as a separate material form, inhabited by thoughts and feelings conceived by analogy to be equally separate, then the only way of getting a society is by adding on a new principle of socialism, social faculty, altruism, or the like. But if you start with the idea that the social person is primarily a fact in the mind, and observe him there, you find at once that he has no existence apart from a mental whole of which all personal ideas are members, and which is a particular aspect of society. Every one of these ideas, as we have seen, is the outcome of our experience of all the persons we have known, and is only a special aspect of our general idea of mankind.
