the libido that we bestow upon an object that makes it attractive and interesting.
The causes for the withdrawal of libido may be various and are usually quite different from those that the persons offer in explanation. It is the task of psychoanalysis to discover the real reasons, which are usually hidden and unknown. On the other hand, when an individual exhibits an exaggerated interest or places an over-emphasis upon an idea or situation, then we know there is too much libido here and that we may find as a consequence a corresponding depletion elsewhere.
This leads directly into the second point of difference between Jung’s views and those of Freud. This is concerned with those practically universal childish manifestations of sexuality called by Freud “polymorphous perverse” because of their similarity to those abnormalities of sexuality which occur in adults and are called perversions.
Jung takes exception to this viewpoint. He sees in the various manifestations of childhood the precursors or forerunners of the later fully developed sexuality, and instead of considering them perverse he considers them preliminary expressions of sexual coloring. He divides human life into three stages. The first stage up to about the third or fourth year, generally speaking, he calls the presexual stage, for there he sees the libido or life energy occupied chiefly in the functions of nutrition and growth, and he draws an analogy between this period and that of the caterpillar stage of the butterfly.
The second stage includes the years from this time
