"Vulnerable Subjects" explores a range of life-writing scenarios - from the "celebrity" to the "ethnographic" - and a number of life-writing genres from parental memoir to literary case studies by Oliver Sacks. G. Thomas Couser addresses complex contemporary issues; he investigates the role of disability in narratives of euthanasia and explores the implications of the Human Genome Project for life-writing practices in an age when many regard DNA as a code that "scripts" lives and shapes identity. Throughout, his book is concerned with the ethical implications of the political and economic, as well as the mimetic, aspects of life writing.
