Third Edition, Revised and Enlarged. Sexual inversion is a term used by sexologists, primarily in the late 19th and early 20th century, to refer to homosexuality. Sexual inversion was believed to be an inborn reversal of gender traits: male inverts were, to a greater or lesser degree, inclined to traditionally female pursuits and dress and vice versa. The sexologist Richard von Krafft-Ebing described female sexual inversion as "the masculine soul, heaving in the female bosom". In its emphasis on gender role reversal, the theory of sexual inversion resembles transgender, which did not yet exist as a separate concept at the time. Initially confined to medical texts, the concept of sexual inversion was given wide currency by Radclyffe Hall's 1928 lesbian novel The Well of Loneliness, which was written in part to popularize the sexologists' views. Published with a foreword by the sexologist Havelock Ellis, it consistently used the term "invert" to refer to its protagonist, who bore a strong resemblance to one of Krafft-Ebing's case studies. Theory - According to this theory, gay men and lesbians were sexual "inverts", people who appeared physically male or female on the outside, but felt internally that they were of the "opposite" anatomical sex (according to the binary view of gender). Therefore, same-gender desires and attraction were explained as "latent heterosexuality", and bisexual desire was known as psychosexual hermaphroditism – in other words, gay men and lesbians were really just heterosexuals who were "born in the wrong body", and "bisexuals" were what modern-day sexologists would call intersexuals (formerly hermaphrodites) by this theory (the bisexual person's "male" part supposedly has attractions towards females, and the "female" part have attractions towards males). There can be no doubt that a peculiar amount of ignorance exists regarding the subject of sexual inversion. I know medical men of many years' general experience who have never, to their knowledge, come across a single case. We may remember, indeed, that some fifteen years ago the total number of cases recorded in scientific literature scarcely equaled those of British race which I have obtained, and that before my first cases were published not a single British case, unconnected with the asylum or the prison, had ever been recorded. Probably not a very large number of people are even aware that the turning in of the sexual instinct toward persons of the same sex can ever be regarded as inborn, so far as any sexual instinct is inborn. And very few, indeed, would not be surprised if it were possible to publish a list of the names of sexually inverted men and women who at the present time are honorably known in church, state, society, art, or letters. It could not be positively affirmed of all such persons that they were born inverted, but in most the inverted tendency seems to be instinctive, and appears at a somewhat early age. In any case, however, it must be realized that in this volume we are not dealing with subjects belonging to the lunatic asylum, or the prison. We are concerned with individuals who live in freedom, some of them suffering intensely from their abnormal organization, but otherwise ordinary members of society. In a few cases we are concerned with individuals whose moral or artistic ideals have widely influenced their fellows, who know nothing of the peculiar organization which has largely molded those ideals.
