Generating Difference

Explores the intersection of racial thought and reproductive science and policy across the British Empire.

In Generating Difference, Andrew Wells traces the entwined histories of race, sex, and reproduction in Britain and its empire during the long eighteenth century. Challenging the assumption that the concept of race evolved in the modern era solely through new forms of biological science, Wells argues that older ideas of lineage, sexual reproduction, and bodily difference remained central to how race was understood, categorized, and enforced well into the nineteenth century.

From the pages of Enlightenment science to colonial policy in the Caribbean, South Asia, and the Pacific, Wells shows how reproductive sex served as a primary framework for defining human differences. Concepts of identity were written onto bodies-especially those marked as non-white or non-male-through perceived differences in anatomy, fertility, and sexuality, albeit never unproblematically. Whether in debates about slavery, interracial relationships, embryology, or population policy, the reproductive body became the crucible in which ideas about race and sex were forged and maintained.

Offering a global scope beyond the Atlantic, including South Asia and the Pacific, and drawing from a wide range of sources-from satire to scientific treatises-Generating Difference brings the scholarship of race and sexuality into direct and compelling conversation. Wells uncovers how deeply reproduction structured imperial ideologies and how the policing of bodies helped naturalize hierarchy, control, and exclusion. At its core, the book reconsiders what made difference "visible" in a period before the dominance of the idea of racial biology.
