[11] According to a report in Vol. 6 of the Jahrbuch f. sexuelle
Zwischenstufen, E. Gley is supposed to have been the first to mention
bisexuality as an explanation of inversion. He published a paper (Les
Abérrations de l'instinct Sexuel) in the Revue Philosophique as early as
January, 1884. It is moreover noteworthy that the majority of authors
who trace the inversion to bisexuality assume this factor not only for
the inverts but also for those who have developed normally, and justly
interpret the inversion as a result of a disturbance in development.
Among these authors are Chevalier (Inversion Sexuelle, 1893), and v.
Krafft-Ebing ("Zur Erklärung der konträren Sexualempfindung," Jahrbücher
f. Psychiatrie u. Nervenheilkunde, XIII), who states that there are a
number of observations "from which at least the virtual and continued
existence of this second center (of the underlying sex) results." A Dr.
Arduin (Die Frauenfrage und die sexuellen Zwischenstufen, 2d vol. of the
Jahrbuch f. sexuelle Zwischenstufen, 1900) states that "in every man
there exist male and female elements." See also the same Jahrbuch, Bd.
I, 1899 ("Die objektive Diagnose der Homosexualitat," by M. Hirschfeld,
pp. 8-9). In the determination of sex, as far as heterosexual persons
are concerned, some are disproportionately more strongly developed than
others. G. Herman is firm in his belief "that in every woman there are
male, and in every man there are female germs and qualities" (Genesis,
das Gesetz der Zeugung, 9 Bd., Libido und Manie, 1903). As recently as
1906 W. Fliess (Der Ablauf des Lebens) has claimed ownership of the idea
of bisexuality (in the sense of double sex). Psychoanalytic
investigation very strongly opposes the attempt to separate homosexuals
from other persons as a group of a special nature. By also studying
sexual excitations other than the manifestly open ones it discovers that
all men are capable of homosexual object selection and actually
accomplish this in the unconscious. Indeed the attachments of libidinous
feelings to persons of the same sex play no small rôle as factors in
