In this special issue, contributors trace how sexual scientific thought circulated throughout the late nineteenth and twentieth centuries and how that thought continues to shape sexuality. The authors situate the science of sex within a broader context of sexuality studies, which examines the social, psychological, and political aspects of desires, acts, identities, and sexology. Articles-addressing topics such as early gender clinics and transsexual etiology, the taxonomy of queer identities, and blackness and sexology-examine the current and historical ways in which racial science and colonial knowledge constitute sexual science as an amorphous object, one with a problematically vast reach that buttresses racial hierarchy and undergirds colonial infrastructures. The authors urge readers to explore how the taxonomies of sexual science structure identitarian frameworks of gender and sexuality. Contributors: Kadji Amin, Howard Chiang, Stephanie D.

Statue-fondlers, wanderlusters, sex magicians, and nymphomaniacs: the story of these forgotten sexualities—what Michel Foucault deemed “minor perverts�—has never before been told. In The Book of Minor Perverts, Benjamin Kahan sets out to chart the proliferation of sexual classification that arose with the advent of nineteenth-century sexology. The book narrates the shift from Foucault’s “thousand aberrant sexualities� to one: homosexuality. The focus here is less on the effects of queer identity and more on the lines of causation behind a surprising array of minor perverts who refuse to fit neatly into our familiar sexual frameworks. The result stands at the intersection of history, queer studies, and the medical humanities to offer us a new way of feeling our way into the past.

In this innovative study, Benjamin Kahan traces the elusive history of modern celibacy. Arguing that celibacy is a distinct sexuality with its own practices and pleasures, Kahan shows it to be much more than the renunciation of sex or a cover for homosexuality. Celibacies focuses on a diverse group of authors, social activists, and artists, spanning from the suffragettes to Henry James, and from the Harlem Renaissance's Father Divine to Andy Warhol. This array of figures reveals the many varieties of celibacy that have until now escaped scholars of literary modernism and sexuality. Ultimately, this book wrests the discussion of celibacy and sexual restraint away from social and religious conservatism, resituating celibacy within a history of political protest and artistic experimentation. Celibacies offers an entirely new perspective on this little-understood sexual identity and initiates a profound reconsideration of the nature and constitution of sexuality.

"With Heinrich Kaan's book we have then what could be called the date of birth, or in any case the date of the emergence, of sexuality and sexual aberrations in the psychiatric field." Michel Foucault, Abnormal: Lectures at the College de France, 1974-1975. Heinrich Kaan's fascinating work-part medical treatise, part sexual taxonomy, part activist statement, and part anti-onanist tract-takes us back to the origins of sexology. He links the sexual instinct to the imagination for the first time, creating what Foucault called "a unified field of sexual abnormality." Kaan's taxonomy consists of six sexual aberrations: masturbation, pederasty, lesbian love, necrophilia, bestiality, and the violation of statues. Kaan not only inaugurated the field of sexology, but played a significant role in the regimes of knowledge production and discipline about psychiatric and sexual subjects. As Benjamin Kahan argues in his Introduction, Kaan's text crucially enables us to see how homosexuality replaced masturbation as the central concern of Euro-American sexual regulation. Kaan's work (translated into English for the first time here) opens a new window onto the history of sexuality and the history of sexology and reconfigures our understanding of Richard von Krafft-Ebing's book of the same name, published some forty years later.
