This book explores the role of the missing in human communities, asking an urgent question: How does a person become a nonperson, whether by disappearance, disenfranchisement, or civil, social, or biological death? Only somebody can become a "nobody," but, as Daniel Heller-Roazen shows, the ways of being a nonperson are as diverse and complex as they are mysterious and unpredictable. Heller-Roazen treats the variously missing persons of the subtitle in three parts: Vanishings, Lessenings, and Survivals. In each section and with multiple transhistorical and transcultural examples, he challenges the categories that define nonpersons in philosophy, ethics, law, and anthropology.
