(a) through a comparison between the other and one’s self, or (b) through a comparison altogether within the other, or (c) through a comparison altogether within one’s self. In the first case the other would appear to me as a child, in the second he would put himself on the level of a child, and in the third I would find the child in myself. To the first class belong the comic of movement and of forms, of psychic activity and of character. The infantile corresponding to it would be the motion-impulse and the inferior mental and moral development of the child, so that the fool would perhaps become comical to me by reminding me of a lazy child, and the bad person by reminding me of a naughty child. The only time one might speak of a childish pleasure lost to grown-ups would be where the child’s own motion pleasure came into consideration. The second case, in which the comic altogether depends on identification with the other, comprises numerous possibilities such as the comic situation, exaggeration (caricature), imitation, degradation, and unmasking. It is under this head that the presentation of infantile viewpoints mostly take place. For the comic situation is largely based on embarrassment, in which we feel again the helplessness of the child. The worst of these embarrassments, the disturbance of other activities through the imperative demands of natural wants, corresponds to the child’s lack of control of the physical functions. Where the comic situation acts through repetitions it is based on the pleasure of constant repetition peculiar to the child (asking questions, telling stories), through which it makes itself a nuisance to grown-ups. Exaggeration, which also affords pleasure even to the grown-up in so far as it is justified by his reason, corresponds to the characteristic want of moderation in the child, and its ignorance of all quantitative relations which it later really learns to know as qualitative. To keep within bounds, to practice moderation even in permissible feelings is a late fruit of education, and is gained through opposing inhibitions of the psychic activity acquired in the same association. Wherever this association is weakened as in the unconscious of dreams and in the monoideation of the psychoneuroses, the want of moderation of the child again makes its appearance.
