remains, so far as the sexual impulse itself is concerned, heterosexual,
that is to say, normal. Inversion of this kind leads a person to feel like
a person of the opposite sex, and to adopt, so far as possible, the
tastes, habits, and dress of the opposite sex, while the direction of the
sexual impulse remains normal. This condition I term sexo-esthetic
inversion, or Eonism.

The nomenclature of the highly important form of sexual
perversion with which we are here concerned is extremely varied,
and most investigators have been much puzzled in coming to a
conclusion as to the best, most exact, and at the same time most
colorless names to apply to it.

The first in the field in modern times was Ulrichs who, as early
as 1862, used the appellation "Uranian" (Uranier), based on the
well-known myth in Plato's _Banquet_. Later he Germanized this
term into "Urning" for the male, and "Urningin" for the female,
and referred to the condition itself as "Urningtum." He also
invented a number of other related terms on the same basis; some
of these terms have had a considerable vogue, but they are too
fanciful and high-strung to secure general acceptance. If used in
other languages than German they certainly should not be used in

term "Urning" in English. "Uranian" is more correct.

In Germany the first term accepted by recognized scientific
authorities was "contrary sexual feeling" (Konträre
Sexualempfindung). It was devised by Westphal in 1869, and used
by Krafft-Ebing and Moll. Though thus accepted by the earliest
authorities in this field, and to be regarded as a fairly
