Why is Pain a Sexual Stimulant?—It is the Most Effective Method of Arousing Emotion—Anger and Fear the Most Powerful Emotions—Their Biological Significance in Courtship—Their General and Special Effects in Stimulating the Organism—Grief as a Sexual Stimulant—The Physiological Mechanism of Fatigue Renders Pain Pleasurable.
We have seen that the distinction between "sadism" and "masochism" cannot be maintained; not only was even De Sade himself something of a masochist and Sacher-Masoch something of a sadist, but between these two extreme groups of phenomena there is a central group in which the algolagnia is neither active nor passive. "Sadism" and "masochism" are simply convenient clinical terms for classes of manifestations which quite commonly occur in the same person. We have further found that—as might have been anticipated in view of the foregoing result—it is scarcely correct to use the word "cruelty" in connection with the phenomena we have been considering. The persons who experience these impulses usually show no love of cruelty outside the sphere of sexual emotion; they may even be very intolerant of cruelty. Even when their sexual impulses come into play they may still desire to secure the pleasure of the persons who arouse their sexual emotions, even though it may not be often true that those who desire to inflict pain at these moments identify themselves with the feelings of those on whom they inflict it. We have thus seen that when we take a comprehensive survey of all these phenomena a somewhat general formula will alone cover them. Our conclusion so far must be that under certain abnormal circumstances pain, more especially the mental representation of pain, acts as a powerful sexual stimulant.
The reader, however, who has followed the discussion to this point will be prepared to take the next and final step in our discussion and to reach a more definite conclusion. The question naturally arises: By what process does pain or its mental representation thus act as a sexual stimulant? The answer has over and over again been suggested by the facts brought forward in this study. Pain acts as a sexual stimulant because it is the most powerful of all methods for arousing emotion.
The two emotions most intimately associated with pain are anger and fear. The more masculine and sthenic emotion of anger, the more passive and asthenic emotion of fear, are the fundamental animal emotions through which, on the psychic side, the process of natural selection largely works. Every animal in some degree owes its survival to the emotional reaction of anger against weaker rivals, to the emotional reaction of fear against stronger rivals. To this cause we owe it that these two emotions are so powerfully and deeply rooted in the whole zoölogical series to which we belong. But anger and fear are not less fundamental in the sexual life. Courtship on the male's part is largely a display of combativity, and even the very gestures by which the male seeks to appeal to the female are often those gestures of angry hostility by which he seeks to intimidate enemies. On the female's part courtship is a skillful manipulation of her own fears, and, as we have seen elsewhere, when studying the phenomena of modesty, that fundamental attitude of the female in courtship is nothing but an agglomeration of fears.
The biological significance of the emotions is now well recognized. "In general," remarks one of the shrewdest writers on animal psychology, "we may say that emotional states are, under natural conditions, closely associated with behavior of biological value—with tendencies that are beneficial in self-preservation and race preservation—with actions that promote survival, and especially with the behavior which clusters round the pairing and parental instincts. The value of the emotions in animals is that they are an indirect means of furthering survival." (Lloyd Morgan, Animal Behavior, p. 293.) Emotional aptitudes persist not only by virtue of the fact that they are still beneficial, but because they once were; that is to say, they may exist as survivals. In this connection I may quote from a suggestive paper on "Teasing and Bullying," by F. L. Burk; at the conclusion of this study, which is founded on a large body of data concerning American children, the author asks: "Accepting for the moment the theories of Spencer and Ribot upon the transmission of rudimentary instincts, is it possible that the movements which comprise the chief elements of bullying, teasing, and the egotistic impulses in general of the classes cited—pursuing, throwing down, punching, striking, throwing missiles, etc.—are, from the standpoint of consciousness, broken neurological fragments, which are parts of old chains of activity involved in the pursuit, combat, capture, torture, and killing of men and enemies?... Is not this hypothesis of transmitted fragments of instincts in accord with the strangely anomalous fact that children are at one moment seemingly cruel and at the next affectionate and kind, vibrating, as it were, between two worlds, egotistic and altruistic, without conscious sense of incongruity?" (F. L. Burk, "Teasing and Bullying," Pedagogical Seminary, April, 1897.)
The primitive connection of the special emotions of anger and fear with the sexual impulse has been well expressed by Colin Scott in his remarkable study of "Sex and Art": "If the higher forms of courting are based on combat, among the males at least anger must be intimately associated with love. And below both of these lies the possibility of fear. In combat the animal is defeated who is first afraid. Competitive exhibition of prowess will inspire the less able birds with a deterring fear. Young grouse and woodcock do not enter the lists with the older birds, and sing very quietly. It is the same with the very oldest birds. Audubon says that the old maids and bachelors of the Canada goose move off by themselves during the courting of the younger birds. In order to succeed in love, fear must be overcome in the male as well as in the female. Courage is the essential male virtue, love is its outcome and reward. The strutting, crowing, dancing, and singing of male birds and the preliminary movements generally of animals must gorge the neuromotor and muscular systems with blood and put them in better fighting trim. The effects of this upon the feelings of the animal himself must be very great. Hereditary tendencies swell his heart. He has 'the joy that warriors feel.' He becomes regardless of danger, and sometimes almost oblivious of his surroundings. This intense passionateness must react powerfully on the whole system, and more particularly on those parts which are capable, such as the brain, of using up a great surplus of blood, and on the naturally erethic functions of sex. The flood of anger or fighting instinct is drained off by the sexual desires, the antipathy of the female is overcome, and sexual union successfully ensues.... Courting and combat shade into one another, courting tending to take the place of the more basal form of combat. The passions which thus come to be associated with love are those of fear and anger, both of which, by arousing the whole nature and stimulating the nutritive sources from which they flow, come to increase the force of the sexual passion to which they lead up and in which they culminate and are absorbed," (Colin Scott, "Sex and Art," American Journal of Psychology, vol. vii, No. 2, pp. 170 and 215.)
It must be remembered that fear is an element liable to arise in all courtship on one side or the other. It is usually on the side of the female, but not invariably. Among spiders, for instance, it is usually the male who feels fear, and very reasonably, for he is much weaker than the female. "Courtship by the male spider" says T. H. Montgomery ("The Courtship of Araneads," American Naturalist, March, 1910, p. 166), "results from a combination of the state of desire for and fear of the female." It is by his movements of fear that he advertises himself to the female as a male, and it is by the same movements that he is unconsciously impelled to display prominently his own ornamentation.
We are thus brought to those essential facts of primitive courtship with which we started. But we are now able to understand more clearly how it is that alien emotional states became abnormally associated with the sexual life. Normally the sexual impulse is sufficiently reinforced by the ordinary active energies of the organism which courtship itself arouses, energies which, while they may be ultimately in part founded on anger and fear, rarely allow these emotions to be otherwise than latent. Motion, it may be said, is more prominent than emotion.
