In The Inner Life of Race, Leerom Medovoi turns away from conventional views of race as a politics of the phenotypical body to theorize race instead as a politics of populational threat. Racism’s genealogy, argues Medovoi, invokes longstanding theological distinctions between the body and the soul. While the body can be seen and marked, the soul signals potentially threatening interiorities: dangerous intentions, beliefs, or desires. Race is the power-effect of reading the body in order to police the political threat of the soul. Medovoi’s genealogy begins with medieval deployments of inquisition and confession to wage war against heretics, infidels, and their threat to the salvation of souls. In early modern Spain, these pastoral technologies of power catalyzed the invention of race as a language for the danger of formerly Jewish and Muslim converts. Medovoi shows how this discourse expanded into anti-blackness and anti-indigeneity throughout the colonial world and modern Europe, laying the foundation for racialized capitalism and liberal governmentality. Medovoi weaves histories of color-line racism, nativism, Islamophobia, antisemitism, and anticommunism into a pathbreaking account of the political work populational racism accomplishes.
