The relations to one another and to the mind of the various persons one thinks of might be rudely pictured in some such way as this. Suppose we conceive the mind as a vast wall covered with electric-light bulbs, each of which represents a possible thought or impulse whose presence in our consciousness may be indicated by the lighting up of the bulb. Now each of the persons we know is represented in such a scheme, not by a particular area of the wall set apart for him, but by a system of hidden connections among the bulbs which causes certain combinations of them to be lit up when his characteristic symbol is suggested. If something presses the button corresponding to my friend A, a peculiarly shaped figure appears upon the wall; when that is released and B’s button is pressed another figure appears, including perhaps many of the same lights, yet unique as a whole though not in its parts; and so on with as many people as you please. It should also be considered that we usually think of a person in relation to some particular social situation, and that those phases of him that bear on this situation are the only ones vividly conceived. To recall someone is commonly to imagine how this or that idea would strike him, what he would say or do in our place, and so on. Accordingly, only some part, some appropriate and characteristic part, of the whole figure that might be lighted up in connection with a man’s symbol, is actually illuminated. To introduce the self into this illustration we might say that the lights near the centre of the wall were of a particular color—say red—which faded, not too abruptly, into white toward the edges. This red would represent self-feeling, and other persons would be more or less colored by it accordingly as they were or were not intimately identified with our cherished activities. In a mother’s mind, for instance, her child would lie altogether in the inmost and reddest area. Thus the same sentiment may belong to the self and to several other persons at the same time. If a man and his family are suffering from his being thrown out of work his apprehension and resentment will be part of his idea of each member of his family, as well as part of his self-idea and of the idea of people whom he thinks to blame.
