Eros and Illness explores the place of desire in illness. We urgently need such an exploration because illness is no longer simply a natural feature of the human condition. Most people fall ill, but illness now falls under the supervision of biomedicine, a science-based, state-regulated system dominated by the new molecular gaze. The use of a person's distinctive genetic data to guide treatment and to forestall disease--called "personalized medicine"-- reflects how the molecular gaze can produce valuable advances in biomedical healthcare. What does this indispensable super-vision, however, tend to overlook? Eros and Illness proposes that biomedicine ignores, in clinical practice and in bench science, the powerful role of desire in illness. Desire, always double-edged, requires attention because it can do both great harm and great good. Patients, caregivers, family members, and physicians, as they recognize the role of desire, gain access to a power that can make the passage through illness much less onerous and far more healing: truly "personalized." --
