Note 194 — Chapter V

In a book on degeneration it is not possible wholly to avoid the subject of eroticism, which includes precisely the most characteristic and conspicuous phenomena of degeneration. I dwell, however, on principle as little as possible on this subject, and will, therefore, in reference to the characterization of Wagner’s erotic madness, quote only one clinical work: Dr. Paul Aubry, ‘Observation d’Uxoricide et de Libéricide suivis du Suicide du Meurtrier,’ Archives de l’Anthropologie criminelle, vol. vii., p. 326: ‘This derangement [erotic madness] is characterized by an inconceivable fury of concupiscence at the moment of approach.’ And in a remark on the report of a murder perpetrated on his wife and children by an erotic maniac—a professor of mathematics in a public school—whom Aubrey had under his observation, he says, ‘Sa femme qui parlait facilement et à tous des choses que l’on tient ordinairement le plus secrètes, disait que son mari était comme un furieux pendant l’acte sexuel.’ See also Ball, La Folie érotique. Paris, 1891, p. 127.
