This volume offers a carefully argued, compelling theory of bioethics while eliciting practical implications for a wide array of issues including medical assistance-in-dying, the right to health care, abortion, animal research, and the definition of death. The authors' dual-value theory features mid-level principles, a distinctive model of moral status, a subjective account of well-being, and a cosmopolitan view of global justice. In addition to ethical theory, the book investigates the nature of harm and autonomous action, personal identity theory, and the 'non-identity problem' associated with many procreative decisions. Readers new to particular topics will benefit from helpful introductions, specialists will appreciate in-depth theoretical explorations and a novel take on various practical issues, and all readers will benefit from the book's original synoptic vision of bioethics. This title is also available as Open Access on Cambridge Core.
