The fundamental form of so-called sadism may be discovered in an erotic type which I will call the seeker of love. A lover of this type is characterised by an unappeasable longing for pure, spiritual love; he passes from woman to woman in the hope of realising this desire, but owing to his own material disposition he is unable to do so. Time after time he succumbs to sexual promptings. Thus groping, frequently quite unconsciously--for a fictitious being, he hates every woman whose fate it is to rouse his desire, for each one cheats him out of that which he seeks. A genuine illusionist, he knows nothing of the woman of flesh and blood, and continues seeking his ideal, only to be again and again disappointed. He blames every woman he conquers for what is really his own insufficiency; he despises her or revenges himself on her, punishes and ill-treats her; we recognise the true Don Juan and his morbid caricature, the sadist. But even the most brutal representative of this type may still be psychologically described as "a man who seeks spiritual love in woman after woman and, finding only sexuality, revenges himself on her." Quite a number of men harbour sadistic feelings for only one woman, and that the one to whom they owe their great disillusionment. Doubtless many men have almost lost the psychical roots of their perversions and are completely involved in physical acts. There is nothing remarkable in this fact; it occurs in every sphere of human life. The vague instinct of revenge on woman animates also, though perhaps unconsciously, the pathological sadist.
