much in common with the primitive mind, which, as mythology and folklore show, attributes great importance to the excretory functions." Many of these ceremonials one regularly discovers in the analyses of neurotics. We shall not dwell further here upon the erogenous zones activity in the suckling, but emphasizing again its importance along with the importance of autoeroticism in the sexuality of the suckling will pass to the next phase of the psycho-sexual evolution of man--the latent period. The germs of sexual excitement in the new-born develop for a time, then undergo a progressive suppression in a period of partial or complete sexual latency. During this period, which is normally interrupted at about the third or fourth year, as result of organic evolutionary processes and the indispensable help of education, those mental forces are formed which appear later as inhibitions to the sexual instinct and narrow its course like dams; mental forces such as disgust, the feeling of shame, the esthetic and moral standards of ideas. During this "latent period" a part of these sexual energies is separated from the sexual aim and applied to cultural and social ends, a process which Freud has designated by the name sublimation as important for culture, history and the individual. Sublimation or the socialization of the sexuality therefore is the transformation and utilization of certain components of the sexual instinct for aims no longer sexual in nature. At the end of the latency period the child's sexuality reappears, frequently but not necessarily induced prematurely by seduction. In addition to the autoerotic gratifications spoken of above, the child is now capable of the choice of a love-object accompanied by erotic feelings. Because of the dependency of the child this first choice of a love-object is directed towards parents and nurses either of his own or of the opposite sex. "Incest complex"--Now too the child under the influence of occasional seduction may become polymorphous-perverse, that is, may become subject to any form of sexual perversion. He likewise shows a preference in the selection of his love-object for his own sex, homo-sexuality.
