Book excerpt: Late in life, Foucault identified with &“the critical tradition of Kant,&” encouraging us to read both thinkers in new ways. Kant&’s &“Copernican&” strategy of grounding knowledge in the limits of human reason proved to stabilize political, social-scientific, and medical expertise as well as philosophical discourse. These inevitable limits were made concrete in historical structures such as the asylum, the prison, and the sexual or racial human body. Such institutions built upon and shaped the aesthetic judgment of those considered &“normal.&” Following Kant through all of Foucault&’s major works, this book shows how bodies functioned as &“problematic objects&” in which the limits of post-Enlightenment European power and discourse were imaginatively figured and unified. It suggests ways that readers in a neoliberal political order can detach from the imaginative schemes vested in their bodies and experiment normatively with their own security needs.
