This article explores the relationship between sexual science and evolutionary models of human development and progress. It examines the ways in which late 19th- and early 20th-century Western European sexual scientists constructed the sexual instinct as an evolutionary force that not only served a reproductive purpose, but was also pivotal to the social, moral, and cultural development of human societies. Sexual scientists challenged the idea that non-reproductive sexualities were necessarily perverse, pathological, or degenerative by linking sexual desire to the evolution (...) of sociality, often focusing on forms of relationality and care that exceeded biological kinship. As a result, non-reproductive sexual expressions, including homosexual and non-reproductive heterosexual behaviours, were interpreted as manifestations of a sexual instinct operating in the service of human development. These claims were reliant on cross-cultural and historical comparisons of sexual values, behaviours, and customs that rehearsed and reinforced imperial narratives of development premised on racialized, gendered, and classed hierarchies. Sexual scientists mapped diverse sexual behaviours in terms of their perceived evolutionary benefits, contributing to colonial narratives that distinguished between different cultures according to imagined trajectories of development. These contestations around the sexual instinct and its developmental functions played a vital role in allowing sexual science to authorize itself as a field of knowledge that promised to provide expertise required to manage sexual life and secure the global development of human civilization.

This article discusses the term erotology, which was applied to medieval Islamicate ‘ilm al-bah (the science of coitus), as well as other world traditions of sexual knowledge, by European sexologists of the late 19th and early 20th centuries, who contrasted it with their own forms of inquiry into sexual matters in the modern field of sexual science. It argues that the homogenisation and minimisation of all ancient and non-European forms of medical knowledge about sex, even one as substantial as the (...) ‘ilm al-bah tradition, supported a particular story about the origins of sexology's own emergence as a new and unprecedented biomedical and scientific way of knowing, characterised by an opposition assumed between sexuality and religion, by a view of sexual variations as perversions or pathologies, and by a view of Arabs and Muslims as sexually excessive. The article focusses on French, English, German, Austrian, and Italian sources of the 19th century that discussed the history of sexual medicine, relating these accounts to recent attempts to historicise sexology. It considers how forms of colonial hierarchy and exoticist views of non-European cultures impacted the dismissal of ‘ilm al-bah among European sexual scientists and how they may continue to exert an influence on forms of modern historical inquiry that are not attentive to scholarship on medieval Islamicate sexual medicine.
