_Bloch_ introduces a third type, the pseudo-Don Juan, or more correctly, the pseudo-Cassanova,—the adventurer perennially disappointed in his conquests, of whom Retif de la Bretonne is the nearest widely known type. He is continually looking for the true love and never finds it. While I admit that the seducer as a type belongs to one of these categories, I must designate all three classes mentioned above, that is, the Don Juan, the Cassanova, and the would-be type of either, as bearers, alike, of a latent homosexuality. None of them finds his ideal. Retif de la Bretonne is the perennially disappointed type, and true love is something he can never find; in his love he displays considerable dependence on woman. He portrays the hopeless flight to woman and away from man. Cassanova feels all the time impelled to prove to himself how seductive a fellow and man he is and every new conquest gives him a new opportunity to do so. Woman is to him but a means to enhance his sense of virility. He must not depreciate his conquest for the glory of his achievement would be lessened in his own eyes if he were to do so. The Don Juan type is close to the level which leads directly to the well known Marquis de Sade type of character. He scorns woman because she is incapable of yielding to him all the gratification for which he yearns. He is perennially searching for release and in that respect bears some resemblance to the Flying Dutchman who is similarly in quest of love and whom the quest leads eventually to death. But I cannot concur with the idea that these types are so sharply differentiated as _Schmitz_ and _Bloch_ are inclined to maintain. We meet the finest gradations and the most varied combinations. Moreover individuals change, their character shifting from one type to another by imperceptible degrees in the course of time. I propose to consider Don Juan as the representative of the type of seducer, irrespective of further variations. In fact it is characteristic of all the types mentioned above that they are alike unable to remain loyal in their love. And, in my view, this is the most important characteristic.
