If the suckling could express himself, he would probably recognize the act of sucking at his mother’s breast as the most important thing in life. He is not so far wrong, for in this one act he satisfies two great needs of life. With no small degree of surprise we learn through psychoanalysis how much of the physical significance of this act is retained through life. The sucking at the mother’s breast becomes the term of departure for all of sexual life, the unattained ideal of later sex gratification, to which the imagination often reverts in times of need. The mother’s breast is the first object for the sexual instinct; I can scarcely bring home to you how significant this object is for centering on the sexual object in later life, what profound influence it exerts upon the most remote domains of psychic life through evolution and substitution. The suckling, however, soon relinquishes it and fills its place by a part of his own body. The child sucks his thumb or his own tongue. Thereby he renders himself independent of the consent of the outer world in obtaining his sensual satisfactions, and moreover increases the excitement by including a second zone of his body. The erogenous zones are not equally satisfactory; it is therefore an important experience when, as Dr. Lindner puts it, the child while touching his own body discovers the especially excitable genitals, and so finds the way from sucking to onanism.
Through the evaluation of sucking we become acquainted with two decisive characteristics of infantile sexuality. It arises in connection with the satisfaction of great organic needs and behaves auto-erotically, that is to say, it seeks and finds it objects on its own body. What is most clearly discernible during the taking in of food is partially repeated during excretion. We conclude that the nursling experiences pleasure during the excretion of urine and the contents of the intestine and that he soon strives to arrange these acts in a way to secure the greatest possible amount of satisfaction by the corresponding excitement of the erogenous membrane zones. Lou Andreas, with her delicate perceptions, has shown how at this point the outer world first intervenes as a hindrance, hostile to the child’s desire for satisfaction — the first vague suggestion of outer and inner conflicts. He may not let his excretions pass from him at a moment agreeable to him, but only when other persons set the time. To induce him to renounce these sources of satisfaction, everything relating to these functions is declared indecent and must be concealed. Here, for the first time, he is to exchange pleasure for social dignity. His own relation to his excretions is originally quite different. He experiences no disgust toward his faeces, values them as a part of his body from which he does not part lightly, for he uses them as the first “present” he can give to persons he esteems particularly. Even after education has succeeded in alienating him from these tendencies, he transfers the evaluation of the faeces to the “present” and to “money.” On the other hand, he appears to regard his achievements in urination with especial pride.
I know that you have been wanting to interrupt me for a long time and to cry: “Enough of these monstrosities! Excretion a source of sexual gratification that even the suckling exploits! Faeces a valuable substance! The anus a sort of genital! We do not believe it, but we understand why children’s physicians and pedagogues have decidedly rejected psychoanalysis and its results.” No, you have merely forgotten that it was my intention to present to you infantile sexuality in connection with the facts of sexual perversion. Why should you not know that in the case of many grown-ups, homosexuals as well as heterosexuals, the locus of intercourse is transferred from the normal to a more remote portion of the body. And that there are many individuals who confess to a pleasurable sensation of no slight degree in the emptying of the bowels during their entire lives! Children themselves will confirm their interest in the act of defecation and the pleasure in watching the defecation of another, when they are a few years older and capable of giving expression to their feelings. Of course, if these children have previously been systematically intimidated, they will understand all too well the wisdom of preserving silence on the subject. As for the other things that you do not wish to believe, let me refer you to the results of analysis and the direct observation of children, and you will realize that it is difficult not to see these things or to see them in a different light. I do not even object to making the relation between child-sexuality and sexual perversion quite obvious to you. It is really only natural; if the child has sexual life at all, it must necessarily be perverse, because aside from a few hazy illusions, the child does not know how sexuality gives rise to reproduction. The common characteristic of all perversions, on the other hand, is that they have abandoned reproduction as their aim. We term sexual activity perverse when it has renounced the aim of reproduction and follows the pursuit of pleasure as an independent goal. And so you realize that the turning point in the development of sexual life lies in its subjugation to the purpose of reproduction. Everything this side of the turning point, everything that has given up this purpose and serves the pursuit of pleasure alone, must carry the term “perverse” and as such be regarded with contempt.
Permit me, therefore, to continue with my brief presentation of infantile sexuality. What I have told you about two organic systems I could supplement by a discussion of all the others. The sexual life of the child exhausts itself in the exercise of a series of partial instincts which seek, independently of one another, to gain satisfaction from his own body or from an external object. Among these organs the genitals speedily predominate. There are persons who continue the pursuit of satisfaction by means of their own genitals, without the aid of another genital or object, uninterruptedly from the onanism of the suckling to the onanism of necessity which arises in puberty, and even indefinitely beyond that. The theme of onanism alone would occupy us for a long period of time; it offers material for diverse observations.
In spite of my inclination to shorten the theme, I must tell you something about the sexual curiosity of children. It is most characteristic for child sexuality and significant for the study of neurotic symptoms. The sexual curiosity of children begins very early, sometimes before the third year. It is not connected with the differences of sexes, which means nothing to the child, since the boy, at any rate, ascribes the same male genital to both sexes. When the boy first discovers the primary sexual structure of the female, he tries at first to deny the evidence of his senses, for he cannot conceive a human being who lacks the part of his body that is of such importance to him. Later he is terrified at the possibility revealed to him and he feels the influence of all the former threats, occasioned by his intensive preoccupation with his little organ. He becomes subject to the domination of the castration complex, the formation of which plays an important part in the development of his character, provided he remains healthy; of his neurosis, if he becomes diseased; of his resistance, if he is treated analytically. We know that the little girl feels injured on account of her lack of a large, visible penis, envies the boy his possession, and primarily from this motive desires to be a man. This wish manifests itself subsequently in neurosis, arising from some failure in her role as a woman. During childhood, the clitoris of the girl is the equivalent of the penis; it is especially excitable, the zone where auto-erotic satisfaction is achieved. In the transition to womanhood it is most important that the sensations of the clitoris are completely transferred at the right time to the entrance of the vagina.
