(c) The partial desires which usually appear in contrasting pairs, play a very prominent role among the symptom-creators in psychoneuroses. They are known as carriers of new sexual aims, such as peeping mania, exhibitionism and the actively and passively formed impulses of cruelty. The contribution of the last is indispensable for the understanding of the morbid nature of the symptoms; it almost regularly controls some portion of the social behavior of the patient. The transformation of love into hatred, of tenderness into hostility, which is characteristic of paranoiacs, takes place by means of the union of cruelty with the libido. The significance of the erogenous zones in relation to inversion is important. Moll’s concept, which divides the sexual impulse into the impulse of contrectation and detumescence, is useful in this field. (Contrectation signifies a desire to touch the skin; detumescence the subsidence of the state of physical sexual preparedness.) “In the perversions, which claim sexual significance for the oral cavity and the anal opening,” as Freud remarks, “the part played by the erogenous zone is quite evident. It behaves in every way like a part of the sexual apparatus. In hysteria, these parts of the body, as well as the tracts of mucous membrane proceeding from them, become the seat of new sensations and innervating changes in a manner similar to the genitals when under the excitement of normal sexual processes.” HOMO-SEXUAL PANIC. Dr. Edward J. Kempf refers to the pressure of uncontrollable perverse cravings as “_acute homosexual panic_,” which is frequently observed whenever men or women are grouped alone for prolonged periods, as in army camps, aboard ships, on exploring expeditions, in prisons, asylums, and schools. The acute panic of the personality is due to the perverse sexual cravings which threaten to overcome the ego, and disestablish the individual’s self-control. At the same time, the affections for winning social esteem are pushed into an eccentric adjustment. The weakness of the ego may be attributed to fatigue, debilitating illness, loss of the love object, homesickness, misfortunes, imposition on the part of a superior, or erotic companions. As the individual shows his eccentricities and irritability, he is often teased and tormented by his fellows. With this there comes a loss of social influence, which develops a sense of inferiority, or strengthens the feeling of inferiority that already exists. The attempt to overcome the fear of inferiority spurs the subject on to intense compensating efforts which, however, because of their eccentric character, further increases the antagonism. Thus we have a vicious circle in the realm of the emotions and affective nature, which gradually becomes a persecution. The erotic individual, under these circumstances, as the perverse sexual impulses tend to force him into further danger, becomes panic-stricken.
