Psychopathia sexualis: With especial reference to contrary sexual instinct / A medico-legal study

by R. von Krafft-Ebing

The perfect counterpart of masochism is sadism. While in the former there is a desire to suffer and be subjected to violence, in the latter the wish is to inflict pain and use violence.

The parallelism is perfect. All the acts and situations used by the sadist in the active rôle become the object of the desire of the masochist in the passive rôle. In both perversions these acts advance from purely symbolic acts to severe maltreatment. Even murder, in which sadism reaches its acme, finds, as is shown by Case 54,—of course, only in fancy,—its passive counterpart. Under favoring conditions, both perversions may occur with a normal vita sexualis; in both, the acts in which they express themselves are preparatory for coitus or substitutes for it.[^[85]]

But the analogy does not exist simply in external manifestation; it also extends to the subjective character of both perversions. Both are to be regarded as original psychopathies in mentally abnormal individuals, who, in particular, are affected with psychical hyperæsthesia sexualis, and, as a rule, also with other abnormalities; and for each of these perversions two constituent elements may be demonstrated, which have their roots in psychical facts lying within physiological limits. For masochism, as shown above, these elements lie in the fact (1) that in the state of sexual emotion every impression produced by the consort, independently of the manner of its production, is, per se, attended with lustful pleasure, which, where there is hyperæsthesia sexualis, may go so far as to over-compensate all painful sensation; and in the fact (2) that “sexual bondage,” dependent on mental factors that are in themselves not perverse, may, under pathological conditions, become a perverse, pleasurable desire for subjection to the opposite sex, which—even if it be quite unnecessary to assume its inheritance from the female side—represents a pathological degeneration of the character belonging to woman,—of the instinct of subordination, physiological in woman.

In harmony with this, there are, likewise, two constituent elements explanatory of sadism, the origin of which may also be traced back within physiological limits. These are: the fact (1) that in sexual emotion, to a certain extent, as an accompanying psychical excitation, an impulse may arise to influence the object of desire in every possible way and with the greatest possible intensity, which, in individuals sexually hyperæsthetic, may become an impulse to inflict pain; and the fact (2) that, under pathological conditions, the man’s active rôle of winning woman may become an unlimited desire for subjugation.

Thus masochism and sadism represent perfect counterparts. It is also in harmony with this that the individuals affected with these perversions regard the opposite perversion in the other sex as their ideal, as shown by Case 44 and Case 50, and also by “Rousseau’s Confessions.”

But the contrast of masochism and sadism may also be used to invalidate the assumption that the former has its origin in the reflex effect of passive flagellation; and that all the rest is the product of associations of related ideas, as Binet, in explanation of Rousseau’s case, thinks, and as Rousseau himself believed.

In the active maltreatment forming the object of the sadist’s sexual desire there is, in fact, no irritation of his own sensory nerves by the act of maltreatment; so that there can be no doubt of the purely psychical character of the origin of this perversion. Sadism and masochism, however, are so related to each other, and so correspond in all points with each other, that the one allows, by analogy, a conclusion for the other; and this is alone sufficient to establish the purely psychical character of masochism.

According to the above-detailed contrast of all the elements and phenomena of masochism and sadism, and as a résumé of all observed cases, lust in the infliction of pain and lust in inflicted pain appear but as two different sides of the same psychical process, of which the primary and essential thing is the consciousness of active or passive subjection, in which the combination of cruelty and lustful pleasure has only a secondary psychological significance. Acts of cruelty serve to express this subjection; first, because they are the most extreme means for the expression of this relation; and, again, because they represent the most intense effect that one person, either with or without coitus, can exert on another.

The cases in which sadism and masochism occur simultaneously in one individual are interesting, but they present some difficulties of explanation. Cases 49, 50, 58, etc., are of this kind, and also particularly Case 30. From the latter it is evident that it is especially the idea of subjection that, both actively and passively, forms the nucleus of the perverse desires. Traces of the same thing are also to be observed, with more or less clearness, in many other cases. At any rate, one of the two perversions is always markedly predominant.

Owing to this marked predominance of one perversion, and the later appearance of the other, in such cases it may well be assumed that the predominating perversion is original, and that the other has been acquired in the course of time. The ideas of subjection and maltreatment, colored with lustful pleasure, either in an active or passive sense, have become deeply impressed in such an individual.
