It might at first sight appear from what has been said that the literature of the sexual life of the child was extremely voluminous, but this is not in reality the case. Almost always, this important question is handled in a casual or cursory manner. A thorough presentation of the subject has not, as far as my knowledge extends, hitherto been attempted. Freud rightly insists that even in all, or nearly all, the works on the psychology of the child, this important department is ignored. Quite recently, indeed, special works have appeared upon the sexual life of the child, among which I must first of all mention Freud's own contribution to the subject, forming part of his _Drei Abhandlungen zur sexuellen Theorie_ (_Three Essays on the Sexual Theory_, Leipzig and Vienna, 1905).[7] But what this writer describes as an indication of infantile sexuality, viz., certain sucking movements, has, in my opinion, nothing to do with the sexual life of the child--as little to do with sexuality as have the functions of the stomach or any other non-genital organ. A number of other processes occurring in childhood, which Freud and his followers have recently described as sexual in nature, and as playing a great part later in life in connexion with hysteria, neurasthenia, compulsion-neuroses, the anxiety-neurosis, and dementia praecox, have very little true relationship to the sexual life of the child. In any case, Freud has not systematically studied the individual manifestations of the sexual life of the child. I must also mention a small work by Koetscher, _Das Erwachen des Geschlechtsbewusstseins und seine Anomalien_ (_The Awakening of the Consciousness of Sex and its Anomalies_, Wiesbaden, 1907). Koetscher, however, does not give any detailed account of the sexual life of the child; he starts, rather, from the sexual life of the adult, and only as a supplement to his account of this does he give a few data regarding the awakening of the consciousness of sex. In the _American Journal of Psychology_, July 1902, we find an elaborate study of the sexual life of the child. In this paper, _A Preliminary Study of the Emotion of Love between the Sexes_, the writer, Sanford Bell, devotes much attention to the love-sentiments in childhood. He discusses, indeed, only heterosexual, qualitatively normal inclinations, and his essay deals only with the psychological aspects of the question. The processes taking place in the genital organs do not come within the scope of the writer's observations, and, indeed, are outside the limits of his chosen theme. A great many other points connected with the question are also left untouched. None the less, the paper is full of matter. The same must be said of the works of the English investigator, Havelock Ellis, who is, in my opinion, the leader of all those at present engaged in the study of sexual psychology and pathology. Unfortunately his writings are not so well known in Germany as they deserve to be, the reason being that
