from the other animals only dawns in him at a later period. He shows at the beginning of life no disgust for excrement, but only learns this feeling slowly under the influence of education; he attaches no particular importance to the difference between the sexes, in fact he thinks that both have the same formation of the genital organs; he directs his earliest sexual desires and his curiosity to those nearest to him or to those who for other reasons are specially beloved—his parents, brothers and sisters or nurses; and finally we see in him a characteristic which manifests itself again later at the height of some love-relationship—namely, he does not look for gratification in the sexual organs only, but discovers that many other parts of the body possess the same sort of sensibility and can yield analogous pleasurable sensations, playing thereby the part of genital organs. The child may be said then to be _polymorphously perverse_, and even if mere traces of all these impulses are found in him, this is due on the one hand to their lesser intensity as compared with that which they assume in later life and, on the other hand, to the fact that education immediately and energetically suppresses all sexual manifestations in the child. This suppression may be said to be embodied in a theory; for grown-up people endeavour to overlook some of these manifestations, and, by misinterpretation, to rob others of their sexual nature, until in the end the whole thing can be altogether denied. It is often the same people who first inveigh against the sexual “naughtiness” of children in the nursery and then sit down to their writing-tables to defend the sexual purity of the same children. When they are left to themselves or when they are seduced children often display perverse sexual activity to a really remarkable extent. Of course grown-up people are right in not taking this too seriously and in regarding it, as they say, as “childish tricks” and “play,” for the child cannot be judged either by a moral or legal code as if he were mature and fully responsible; nevertheless these things do exist, and they have their significance both as evidence of innate constitutional tendencies and inasmuch as they cause and foster later developments: they give us an insight into the child’s sexual life and so into that of humanity as a whole. If then we find all these perverse wishes behind the distortions of our dreams, it only means that dreams in _this respect also_ have regressed completely to the infantile condition.
