Thus a minor degree of the masochistic tendency may be said to be fairly common, while its more pronounced manifestations are more common than pronounced sadism.[94] It very frequently affects persons of a sensitive, refined, and artistic temperament. It may even be said that this tendency is in the line of civilization. Krafft-Ebing points out that some of the most delicate and romantic love-episodes of the Middle Ages are distinctly colored by masochistic emotion.[95] The increasing tendency to masochism with increasing civilization becomes explicable if we accept Colin Scott’s “secondary law of courting” as accessory to the primary law that the male is active, and the female passive and imaginatively attentive to the states of the excited male. According to the secondary law, “the female develops a superadded activity, the male becoming relatively passive and imaginatively attentive to the psychical and bodily states of the female."[96] We may probably agree that this “secondary law of courting” does really represent a tendency of love in individuals of complex and sensitive nature, and the outcome of such a receptive attitude on the part of the male is undoubtedly in well-marked cases a desire of submission to the female’s will, and a craving to experience in some physical or psychic form, not necessarily painful, the manifestations of her activity.
When we turn from vague and unpronounced forms of the masochistic tendency to the more definite forms in which it becomes an unquestionable sexual perversion, we find a very eminent and fairly typical example in Rousseau, an example all the more interesting because here the subject has himself portrayed his perversion in his famous Confessions. It is, however, the name of a less eminent author, the Austrian novelist, Sacher-Masoch, which has become identified with the perversion through the fact that Krafft-Ebing fixed upon it as furnishing a convenient counterpart to the term “sadism.” It is on the strength of a considerable number of his novels and stories, more especially of Die Venus im Pelz, that Krafft-Ebing took the scarcely warrantable liberty of identifying his name, while yet living, with a sexual perversion.
