The demonic interpretation of the Don Juan legend, created by the seventeenth-century French playwright Moliere, and immortalized by Mozart in his opera, 'Don Giovanni', received support in the twentieth century from a strange quarter. The scientific investigation into the private sexual lives of the bourgeoisie and masses was begun early in the twenteith century through the discipline of psychoanalysis. Intially, a psychological therapy for mental illness, psychoanalysis evolved psuedo-scientific theories aimed at explaining such things like character development and differentiation. A famous psychoanalyst by the name of Wilhelm Stekel wrote a book titled, 'Bisexual Love', in which he resurrected the demonic interpretation of the Don Juan character. Basing his claims and conclusions on the clinical study and psychoanalysis of several Don Juan character-types, he reached the startling conclusion that Don Juan was really a repressed homo. In this way, he tries to explain Don Juans' frequent flight and dissatisfation with women. Counterposing Don Juan to Casanova, he argues Don Juan is really a misogynist (woman-hater) and a truly disturbed character-type.
