Studied by criminologists, doctors, nurses, psychologists, psychiatrists and sociologists, the actions of those who harm themselves are often alienating and bewildering. This book provides a historical and conceptual roadmap for understanding self harm across a range of times and places: in modern high schools and in modern warfare; in traditional religious practices and in avant-garde performance art. Describing the diversity of self harm as well as responses to it, this book challenges the understanding of it as a single behavior associated with a specific age group, gender or cultural identity.
