of action, sucking clings entirely to the domain of the function of nutrition, but it presents also a far wider aspect, it is no mere function of nutrition, it is a rhythmical activity, with its goal in a pleasure and satisfaction of its own, distinct from the obtaining of nourishment. The hand comes into play as an accessory organ. In the epoch of the displaced rhythmical activity it stands out still more as an accessory organ, when the oral zone ceases to give pleasure, which must now be obtained in other directions. The possibilities are many. As a rule the other openings of the body become the first objects of interest of the libido; then follow the skin in general and certain places of predilection upon it.
The actions carried out at these places generally take the form of rubbing, piercing, tugging, etc., accompanied by a certain rhythm, and serve to produce pleasure. After a halt of greater or less duration at these stations, the libido proceeds until it arrives at the sexual zone, where it may next provoke the first onanistic attempts. During its "march," the libido carries over not a little from the function of nutrition into the sexual zone; this readily explains the numerous close associations between the function of nutrition and the sexual function.
This "march" of the libido takes place at the time of the pre-*sexual stage, which is characterized by the fact that the libido gradually relinquishes the special character of the instinct of nutrition, and by degrees acquires the character of the sexual instinct. At this stage we cannot yet speak of a true sexual libido. Therefore we are obliged to qualify the polymorphous perverse sexuality of early infancy differently. The polymorphism of the tendencies of the libido at this time is to be explained as the gradual movement of the libido away from the sphere of the function of nutrition towards the sexual function.
The Infantile "Perversity."—Thus rightly vanishes the term "perverse"—so strongly contested by our opponents—for it provokes a false idea.
When a chemical body breaks up into its elements, these elements are the products of its disintegration, but it is not permissible on that account to describe elements as entirely products of disintegration. Perversities are disorders of fully-developed sexuality, but are never precursors of sexuality, although there is undoubtedly an analogy between the precursors and the products of
