Progress from this point is chiefly in the way of a greater definiteness, fulness, and inwardness in the imagination of the other’s state of mind. A little child thinks of and tries to elicit certain visible or audible phenomena, and does not go back of them; but what a grown-up person desires to produce in others is an internal, invisible condition which his own richer experience enables him to imagine, and of which expression is only the sign. Even adults, however, make no separation between what other people think and the visible expression of that thought. They imagine the whole thing at once, and their idea differs from that of a child chiefly in the comparative richness and complexity of the elements that accompany and interpret the visible or audible sign. There is also a progress from the naïve to the subtle in socially self-assertive action. A child obviously and simply, at first, does things for effect. Later there is an endeavor to suppress the appearance of doing so; affection, indifference, contempt, etc., are simulated to hide the real wish to affect the self-image. It is perceived that an obvious seeking after good opinion is weak and disagreeable. I doubt whether there are any regular stages in the development of social self-feeling and expression common to the majority of children. The sentiments of self develop by imperceptible gradations out of the crude appropriative instinct of new-born babes, and their manifestations vary indefinitely in different cases. Many children show “self-consciousness” conspicuously from the first half year; others have little appearance of it at any age. Still others pass through periods of affectation whose length and time of occurrence would probably be found to be exceedingly various. In childhood, as at all times of life, absorption in some idea other than that of the social self tends to drive “self-consciousness” out. Nearly everyone, however, whose turn of mind is at all imaginative goes through a season of passionate self-feeling during adolescence, when, according to current belief, the social impulses are stimulated in connection with the rapid development of the functions of sex. This is a time of hero-worship, of high resolve, of impassioned reverie, of vague but fierce ambition, of strenuous imitation that seems affected, of _gêne_ in the presence of the other sex or of superior persons, and so on.
