Recently the Freudian school has endeavored to penetrate more deeply to the nucleus of the problem and to solve it. Freud has delimited what he calls obsessional or compulsion neurosis (Zwangsneurosis), which is classed under psychasthenia by the French and under neurasthenia by others. The Freudians regard this as a distinct neurosis, sometimes complicated by neurasthenic or hysterical symptoms. The characteristic symptom is a feeling of compulsion. The symptoms may be motor (obsessional acts, impulsions), sensory (obsessional hallucinations or sensations), ideational (obsessions), and affective (obsessive emotions, particularly doubt and fear). In this condition we find that there is an excessive psychical significance attached to certain thoughts. Obsessions are characterized by dissociations from the main personality. They thus exist in the unconsciousness. The original unconscious mental processes have brought about, by displacement, an excess of psychical significance to these thoughts. Ernest Jones[5] states that Freud found, by his work in psychoanalysis, that obsessions represented, symbolically, the return of self-reproaches of ancient, infantile and early childhood origin, which had been repressed and buried until the obsession made its appearance. "They always refer to active sexual performances or tendencies;" and, as Jones further explains, "there occurs early in life an exaggerated divorce between the instincts of hate and love, and the conflict and antagonism between the two dominate the most important reactions of the person. A fundamental state of doubt, an incapacity for decision, results from this paralyzing doubt. The patient oscillates between the two conditions of not being able to act (when he wants to), and of being obliged to act (when he doesn't want to). The symptom symbolizes the conflicting forces. These are not, as in hysteria, fused into a compromise-formation, but come to separate and alternating expression; one set of manifestations, therefore, symbolizes the repressed forces, another the repressing."
