This case is interesting as an uncomplicated example of almost purely ideal sadism. It is interesting to note the feelings of the sadist subject toward her imaginary lover's feelings. It is probably significant that, while his pleasure is regarded as essential, his pain is regarded as even more essential, and the resulting apparent confusion may well be of the very essence of the whole phenomenon. The pleasure of the imaginary lover must be secured or the manifestation passes out of the sexual sphere; but his pleasure must, at all costs, be conciliated with his pain, for in the sadist's eyes the victim's pain has become a vicarious form of sexual emotion. That, at the same time, the sadist desires to give pleasure rather than pain finds confirmation in the fact that he often insists on pleasure being feigned even though it is not felt. Some years ago a rich Jewish merchant became notorious for torturing girls with whom he had intercourse; his performances acquired for him the title of "_l'homme qui pique_," and led to his prosecution. It was his custom to spend some hours in sticking pins into various parts of the girl's body, but it was essential that she should wear a smiling face throughout the proceedings. (Hamon, _La France Sociale et Politique_, 1891, p. 445 et seq.) We have thus to recognize that sadism by no means involves any love of inflicting pain outside the sphere of sexual emotion, and is even compatible with a high degree of general tender-heartedness. We have also to recognize that even within the sexual sphere the sadist by no means wishes to exclude the victim's pleasure, and may even regard that pleasure as essential to his own satisfaction. We have, further, to recognize that, in view of the close connection between sadism and masochism, it is highly probable that in some cases the sadist is really a disguised masochist and enjoys his victim's pain because he identifies himself with that pain.
