other childish bad habits, we conclude that these habits have a sexual character, in so far as they are used to obtain physical satisfaction from the child’s own body. This new standpoint is comprehensible and perhaps necessary. It is only a few steps from this point of view to regarding the infant’s act of sucking as of a sexual character. As you know, Freud took the few steps, but you have just heard me reject them. We have come to a difficulty which is very hard to solve. It would be relatively easy if we could accept two instincts side by side, each an entity in itself. Then the act of sucking the breast would be both an action of nutrition and a sexual act. This seems to be Freud’s conception. We find in adults the two instincts separated, yet existing side by side, or rather we find that there are two manifestations, in hunger, and in the sexual instinct. But at the sucking age, we find only the function of nutrition, rewarded by both pleasure and satisfaction. Its sexual character can only be argued by a petitio principii, for the facts show that the act of sucking is the first to give pleasure, not the sexual function. Obtaining pleasure is by no means identical with sexuality. We deceive ourselves if we think that in the suckling both instincts exist side by side, for then we project into the psyche of the child the facts taken from the psychology of adults. The existence of the two instincts side by side does not occur in suckling, for one of these instincts has no existence as yet, or, if existing, is quite rudimentary. If we are to regard the striving for pleasure as something sexual, we might as well say paradoxically that hunger is a sexual striving, for this instinct seeks pleasure by satisfaction. If this were true, we should have to give our opponents permission to apply the terminology of hunger to sexuality. It would facilitate matters, were it possible to maintain that both instincts existed side by side, but it contradicts the observed facts and would lead to untenable consequences. Before I try to resolve this opposition, I must first say something more about Freud’s sexual theory, and its transformations. The Polymorphic Perverse Sexuality of Infancy
