izations is the _oral_,
or if we wish, the cannibalistic. Here the sexual activity is not yet
separated from the taking of nourishment, and the contrasts within the
same not yet differentiated. The object of the one activity is also that
of the other, the sexual aim consists in the _incorporating_ into one's
own body of the object, it is the prototype of that which later plays
such an important psychic role as _identification_. As a remnant of this
fictitious phase of organization forced on us by pathology we can
consider thumbsucking. Here the sexual activity became separated from
the nourishment activity and the strange object was given up in favor of
one from his own body.

A second pregenital phase is the sadistic-anal organization. Here the
contrasts which run through the whole sexual life are already developed,
but cannot yet be designated as _masculine_ and _feminine_, but must be
called _active_ and _passive_. The activity is supplied by the
musculature of the body through the mastery impulse; the erogenous
mucous membrane of the bowel manifests itself above all as an organ with
a passive sexual aim, for both strivings there are objects present,
which however do not merge together. Besides them there are other
partial impulses which are active in an autoerotic manner. The sexual
polarity and the strange object can thus already be demonstrated in this
phase. The organization and subordination under the function of
propagation are still lacking.

*Ambivalence.*--This form of the sexual organization could be retained
throughout life and continue to draw to itself a large part of the
sexual activity. The prevalence of sadism and the role of the cloaca of
the anal zone stamps it with an exquisitely archaic impression. As
another characteristic belonging to it we can mention the fact that the
contrasting pair of impulses are developed in almost the same manner, a
behavior which was designated by Bleuler with the happy name of
_ambivalence_.

The assumption of the pregenital organizations of the sexual life is
based on the analysis of the neuroses and hardly deserves any
consideration without a knowledge of the same. We may expect that
continued analytic efforts will furnish us with still more disclosures
concerning the structure and development of the normal sexual function.

To complete the picture of the infantile sexual life one must add that
frequently or regularly an object selection takes place even in
chil
