traits characteristic of the other sex. But such inversion of character
can be expected with some regularity only in inverted women; in men the
most perfect psychic manliness may be united with the inversion. If one
firmly adheres to the hypothesis of a psychic hermaphroditism, one must
add that in certain spheres its manifestations allow the recognition of
only a very slight contrary determination. The same also holds true in
the somatic androgyny. According to Halban, the appearance of individual
stunted organs and secondary sex characters are quite independent of
each other.[10]

A spokesman of the masculine inverts stated the bisexual theory in its
crudest form in the following words: "It is a female brain in a male
body." But we do not know the characteristics of a "female brain." The
substitution of the anatomical for the psychological is as frivolous as
it is unjustified. The tentative explanation by v. Krafft-Ebing seems to
be more precisely formulated than that of Ulrich but does not
essentially differ from it. v. Krafft-Ebing thinks that the bisexual
predisposition gives to the individual male and female brain centers as
well as somatic sexual organs. These centers develop first towards
puberty mostly under the influence of the independent sex glands. We
can, however, say the same of the male and female "centers" as of the
male and female brains; and, moreover, we do not even know whether we
can assume for the sexual functions separate brain locations ("centers")
such as we may assume for language.

After this discussion, two notions, at all events, persist; first, that
a bisexual predisposition is to be presumed for the inversion also, only
we do not know of what it consists beyond the anatomical formations;
and, second, that we are dealing with disturbances which are experienced
by the sexual impulse during its development.[11]
