One cannot maintain that the world was very grateful to psychoanalytic research for its discovery of the Oedipus-complex. On the contrary, it called forth the strongest resistance on the part of adults; and persons who had neglected to take part in denying this proscribed or tabooed feeling-relationship later made good the omission by taking all value from the complex through false interpretations. According to my unchanged conviction there is nothing to deny and nothing to make more palatable. One should accept the fact, recognized by the Greek myth itself, as inevitable destiny. On the other hand, it is interesting that this Oedipus-complex, cast out of life, was yielded up to poetry and given the freest play. O. Rank has shown in a careful study how this very Oedipus-complex has supplied dramatic literature with a large number of motives in unending variations, derivations and disguises, also in distorted forms such as we recognize to be the work of a censor. We may also ascribe this Oedipus-complex to those dreamers who were so fortunate as to escape in later life these conflicts with their parents, and intimately associated therewith we find what we call the _castration complex_, the reaction to sexual intimidation or restriction, ascribed to the father, of early infantile sexuality. By applying our former researches to the study of the psychic life of the child, we may expect to find that the origin of other forbidden dream-wishes, of excessive sexual impulses, may be explained in the same manner. Thus we are moved to study the development of sex-life in the child also, and we discover the following from a number of sources: In the first place, it is a mistake to deny that the child has a sexual life, and to take it for granted that sexuality commences with the ripening of the genitals at the time of puberty. On the contrary--the child has from the very beginning a sexual life rich in content and differing in numerous respects from that which is later considered normal. What we call "perverse" in the life of the adult, differs from the normal in the following respects: first, in disregard for the dividing line of species (the gulf between man and animal); second, being insensible to the conventional feeling of disgust; third, the incest-limitation (being prohibited from seeking sexual satisfaction with near blood-relations); fourth, homosexuality, and fifth, transferring the role of the genitals to other organs and other parts of the body. None of these limitations exist in the beginning, but are gradually built up in the course of development and education. The little child is free from them. He knows no unbridgable chasm between man and animal; the arrogance with which man distinguishes himself from the animal is a later acquisition. In the beginning he is not disgusted at the sight of excrement, but slowly learns to be so disgusted under the pressure of education; he lays no special stress on the difference
