What methods are available for the study of the sexual life of the child? Three methods have to be considered: first, the observation of children; secondly, experiment; and thirdly, reports made by individuals regarding their own experiences. As regards the last mentioned, we must distinguish clearly between accounts reproduced from memory long after the incidents to which they relate, and accounts given by children of their state at the time of narration. But both varieties of clinical history are defective. The child is often incompetent to describe his sensations—think, for instance, of the processes of the earliest years of life. Even when the child is able to make reports, a sense of shame will often interfere with the truthfulness of his account. Whilst as regards the memory-pictures of adults, recourse to this method often fails us because the experiences are so remote as to have been largely, if not entirely, forgotten. The autobiographies of sexually perverse individuals have drawn my attention to the fallacious nature of memory. Its records are uncertain, but that especially is recorded which has aroused interest. Not only the interest felt in the experiences at the time determines what shall be recorded, but also the interest felt later when reviving these experiences in memory. Childish experiences are very readily forgotten, either if they were uninteresting at the time, or if subsequently they have become uninteresting. During childhood, a homosexual woman has experienced sexual feeling, directed now towards boys, now towards girls. Later in life, when the homosexuality has developed fully, the memory of the inclination towards boys fades away, and her homosexual sentiments only are remembered. As a result, we often find that the homosexual woman—and the converse is equally true of the homosexual man—declares at first, when inquiries are made, that she has never experienced any inclination for members of the other sex; whereas, at any rate in a large proportion of cases, a stricter examination of her memory, or the reports of other individuals, will reveal beyond dispute that in childhood heterosexual inclinations were not lacking.
A further defect of memory has been made manifest to me by the study of perversions. Processes which in childhood were entirely devoid of any sexual tinge, but which later became associated with sex-feelings, very readily acquire false sexual associations also when they are revived in memory. Consider, for instance, the case of a homosexual man. He remembers that, as a small boy, he was very fond of sitting on his uncle's knees, and he believes that the pleasure he formerly experienced was tinged by sexual feeling. In reality this was by no means the case. His uncle took the boy on his knee in order to tell him a story. Possibly, also, the riding movements which the uncle imitated by jogging his knees up and down gave the child pleasure, which, however, was entirely devoid of any admixture of sexual feeling. But in the consciousness of the full-grown man, in whom homosexual feeling has later undergone full development, all this becomes distorted. The non-sexual motives are forgotten; he believes that even in early childhood he had homosexual inclinations, and that for this reason it gave him pleasure to ride on his uncle's knees.
Nor is observation in any way adapted to furnish us with a clear picture of the sexual life of the child. So little can be directly observed, that in the absence of reports much would remain entirely unknown. From the moment when the children gain a consciousness, however obscure, of the nature of sexual processes, they almost invariably endeavour to conceal their knowledge as much as possible, so that we shall discover its existence only by a rare chance. None the less, the results of direct observation are often important; sometimes because we are able to watch children when they are unaware of our attention, and sometimes because they do not as yet fully understand the nature of the processes under observation, and for this reason are less secretive.
The third method, that of experiment, is available to us only in the form of castration. I need not dilate on the inadequacy of this application of the experimental method, even apart from the fact that it subserves our purposes almost exclusively in respect of the male sex—for in the case of young girls, castration (oöphorectomy) is almost entirely unknown.
Thus we see that all our methods of investigation exhibit extensive lacunæ, and further, that they are all in many respects fallacious; we shall therefore endeavour to supplement each by the others, in order to arrive at results which shall be as free from error as possible. Thus guided, we learn that sexual incidents occur in childhood far more frequently than is usually supposed. So common are they, that they cannot possibly escape the notice of any practising physician or educationalist who pays attention to the question, provided, of course, that he enjoys the confidence of the parents. These latter have often been aware of such sexual manifestations in their children for a long time, but a false shame has prevented them from asking the advice of the physician. They have been afraid lest he should regard the child as intellectually or morally deficient, or as the offspring of a degenerate family. In addition, we have to take into account self-deception on the part of the parents, who, indeed, often deceive themselves willingly, saying to themselves that the matter is of no importance, and that the symptoms will disappear spontaneously.
Having given this brief account of the terminology to be employed and of the methods of investigation, I propose to sketch no less briefly the history of the subject.
Casual references to the sexual life of the child are to be found even in the older scientific literature. In the latter half of the eighteenth century, and at the beginning of the nineteenth, interest in the subject became more general. Two works, in especial, published almost simultaneously, attracted the attention of physicians and educationalists. One of these, Rousseau's Émile, discusses the proper conduct of parents and elders in relation to the awakening sexual life, and what they should do in order to delay that awakening as much as possible. The other, the celebrated work of Tissot, depicts the dangers of masturbation, but deals chiefly with persons who have attained sexual maturity. None the less, in consequence of this book, much attention was directed to the sexual life of the child. Earlier works on masturbation, such as that of Sarganeck, for instance, had not succeeded in arousing any enduring interest in this question. But Rousseau's and Tissot's books induced a large number of physicians and educationalists to occupy themselves in this province of study. Thus at this early day many authorities were led to advocate the sexual enlightenment of children, in order to guide them in the avoidance of the dangers of the sexual life. An excellent historical and critical study of this movement, written by Thalhofer, has recently been published.[4] Among the educationalists who took part in it may be mentioned Basedow, Salzmann, Campe, and Niemeyer. The modern movement in favour of sexual enlightenment originated chiefly in the endeavour to prevent the diffusion of venereal diseases; but the earlier movement, occurring at a time when much less was known about venereal diseases, had a different aim. This was rather to prevent masturbation and other sexual excesses, on account of their direct effect upon the organism; an aim not neglected by the modern movement for sexual enlightenment, though subsidiary to the object of the prevention of the venereal diseases. Teachers of that day touched, of course, upon the subject of the sexual life of the child. But this was done cursorily, for when instruction was given on the sexual life, not the actual experience of children, but the sexual life of mature persons, was the subject of discourse. This must be said also of the works of those physicians who, like Hufeland in his Makrobiotik (written as a sequel to the work of Tissot), spoke of the dangers of masturbation.
A few of the numerous medical books dealing with the puberal development deserve mention in this place; for instance, Marro, La Pubertà (first edition, published in 1897), and Bacqué, La Puberté (Argenteuil, 1876). A number of recent works on masturbation have also touched on the topic of the sexual life of the child.
Apart from these recent special investigations, the older and the more recent medical and anthropological literature contains numerous observations which concern the subject of this book. More especially do we find reports of cases in which the external manifestations of sexual maturity appeared in very early childhood. Now we find an account of a girl menstruating at four years of age, now an account of a three-year-old boy who exhibited many of the external signs of sexual maturity. Even in the older, purely psychological works we find occasional references to the sexual life of the child—a fact that will surprise no one who is acquainted with the high development of the empirical psychology (Erfahrungspsychologie) of that day (1800). The Venus Urania of Ramdohr, for instance, a work on the psychology of love, emphasises the frequency of amatory sentiments in children.
In works dealing with the history of civilisation, we also encounter occasional references to our subject. Take, for instance, the knightly Code of Love (Liebeskodex), a work highly esteemed in the days of chivalry, and legendarily supposed to have originated in King Arthur's Court. Paragraph 6 of this Code runs: "A man shall not practise love until he is fully grown." According to Rudeck,[5] from whom I quote this instance, the aim of the admonition was to protect the youth of the nobility from unwholesome consequences. Obviously, the love affairs of immature persons must have been the determining cause of any allusion to the matter. We may also draw attention in this connexion to many marriage laws, which show that the subject has come under consideration, either because they expressly sanction the marriages of children, or, conversely, because they forbid such unions. At the present day, among many peoples (as, for instance, the Hindus), child-marriages are frequent; and in many countries in which such marriages are now illegal, they were sanctioned in former ages. Many works on prostitution also touch on our chosen subject. Parent-Duchâtelet, in his great book, refers to girls who had become prostitutes at the ages of twelve or even ten years. I shall show later that in individual instances such early prostitution is directly dependent upon the sexuality of the children concerned. Many ethnological works also contribute to our knowledge of the sexual life of the child, describing, as they do, in certain races, the early awakening of sexual activity.
