supposed that there may be an anatomical "homosexual center" in the brain;
i.e., a feminine libido-center in the inverted man, and a masculine
libido-center in the inverted woman. He expressed a hope that in the
future the brains of inverted persons would be more carefully
investigated.

[233] I do not present this view as more than a picture which helps us to
realize the actual phenomena which we witness in homosexuality, although I
may add that so able a teratologist as Dr. J.W. Ballantyne considers that
"it seems a very possible theory."

[234] This explanation of homosexuality has already been tentatively put
forth. Thus, Iwan Bloch (_Sexual Life of Our Time_, ch. xix, Appendix)
vaguely suggests a new theory of homosexuality as dependent on chemical
influences. Hirschfeld also believes (_Die Homosexualitaet_, ch. xx) that
the study of the internal secretions is the path to the deepest
foundations of inversion.

[237] After this chapter was first published (in the _Centralblatt fuer
Nervenheilkunde_, February, 1896), Fere also compared congenital inversion
to color-blindness and similar anomalies (Fere, "La Descendance d'un
Inverti," _Revue Generale de Clinique et Therapeutique_, 1896), while
Ribot referred to the analogy with color-hearing (_Psychology of the
Emotions_, part ii, ch. vii).

[239] Magnan has in recent years reaffirmed this view ("Inversion Sexuelle
et Pathologic Mentale," _Revue de Psychotherapie_, March, 1914): "The
invert is a diseased person, a degenerate."

[240] It is this fact which has caused the Italians to be shy of using the
word "degeneration;" thus, Marro, in his great work, _I Caratteri del
Delinquenti_, made a notable attempt to analyze the phenomena lumped
together as degenerate into
