the different erogenous zones. This conception can be compared with the position of physics before Robert Mayer, when only isolated forces, having elementary qualities, were recognized, whose interchanges were little understood. The law of the conservation of energy brought order into the inter-relationship of the forces, at the same time abolishing the conception of those forces as absolute elements, but regarding them as interchangeable manifestations of one and the same energy.
The Sexual Components as Energic Manifestations
Conceptions of great importance do not arise only in one brain, but are floating in the air and dip here and there, appearing even under other forms, and in other regions, where it is often very difficult to recognize the common fundamental idea. Thus it happened with the splitting up of sexuality into the polymorphic perverse sexuality of childhood.
Experience forces us to accept a constant exchange of isolated components as we notice more and more that, for instance, perversities exist at the expense of normal sexuality, or that the increase of certain kinds of sex-manifestations causes corresponding deficiencies of another kind. To make the matter clearer, let me give you an instance: A young man had a homo-sexual phase lasting for some years, during which time women had no interest for him. This abnormal condition changed gradually toward his twentieth year and his erotic interest became more and more normal. He began to take great interest in girls, and soon the last traces of his homo-sexuality were conquered. This condition lasted several years, and he had some successful love-affairs. Then he wished to get married; he had here to suffer a great disappointment, as the girl to whom he proposed refused him. During the ensuing phase he absolutely abandoned the idea of marriage. After that he experienced a dislike of all women, and one day he discovered that he was again perfectly homo-sexual, that is, young men had an unusually irritating influence upon him. To regard sexuality as composed of a fixed hetero-sexual component, and a like homo-sexual element, will never suffice to explain this case, for the conception of the existence of fixed components excludes any kind of transformation.
