This is a new edition of "Sexual Inversion," originally published in 1915 by F. A. Davis Company, Publishers, of Philadelphia. Part of Adeptio's "The Best of Havelock Ellis Collection," from the "Unforgettable Classic Series," this is not a facsimile reprint. Obvious typographical errors have been carefully corrected and the entire text has been reset and redesigned by Adeptio Editions to enhance readability, while respecting the original edition."Sexual Inversion" was the first English medical textbook on the topic of homosexuality. The book became a part of Ellis's six-volume "Studies in the Psychology of Sex." Havelock Ellis and John Addington Symonds agreed to collaborate on a new study that would combine Symonds's historical analysis on homosexuality with Ellis's experience with medical and scientific theory. Symonds died in 1893 before the book was concluded. "Sexual Inversion" was first published in German in 1896 (Leipzig, by Georg H. Wigand's Verlag) entitled "Das Konträre Geschlechtsgefühl," under Havelock Ellis and John Addington Symonds. Ellis further revised the text and edited several of Symonds's contributions, with almost every page being rewritten or enlarged. This is the third edition."Sexual Inversion" is considered one of Havelock's masterpieces and helped establish Havelock's reputation throughout the world.About the Author: Havelock Ellis was a social activist, a physician and a psychologist, whose best-known works concern sexuality and criminology. Among his over forty books, in 1890 he published "The Criminal," a remarkable work on criminal anthropology. In the same year, he published "The New Spirit," a collection of literary essays on Diderot, Heine, Whitman, Ibsen, and Tolstoy, and Ellis's attempt to synthesize science and religious mysticism. In 1898 he wrote "Affirmations," which contains essays on Nietzsche, Casanova, Zola, Huysmans, and St. Francis. In 1897, he published "Sexual Inversion," the first medical text in English about homosexuality, which he had co-authored with John Addington Symonds in an earlier edition, and which became a part of Ellis's six-volume "Studies in the Psychology of Sex." In 1922, he published "Little Essays of Love and Virtue," which aimed primarily at young people, youths and girls at the period of adolescence, who were in the author's thoughts in all the studies he wrote of sex because he was of that age when he first vaguely planned them. These titles are part of our "Unforgettable Classic Series: The Best of Havelock Ellis Collection." Born in Surrey, England, in 1859, Havelock Ellis was considered by the overwhelming majority of critics as the best translator of "Germinal," Émile Zola`s masterpiece. Ellis was associated with the Decadent movement and with the "Lutetian Society," a secret literary society, through which authors and translators like himself were able to provide British readers with translations of works which were often antagonistic to the Victorian ideals of morality-such as some of Émile Zola's controversial novels-aiming at expanding the cultural horizons of the few lucky readers who had access to them. Havelock Ellis died in Suffolk, England, in 1939.
