Life Before Birth provides a coherent framework for addressing bioethical issues in which the moral status of embryos and fetuses is relevant. It is based on the "interest view" which ascribes moral standing to beings with interests, and connects the possession of interests with the capacityfor conscious awareness or sentience. The theoretical framework is applied to ethical and legal topics, including abortion, prenatal torts, wrongful life, the crime of feticide, substance abuse by pregnant women, compulsory cesareans, assisted reproduction, and stem cell research. Along the way,difficult philosophical problems, such as identity and the non-identity problem are thoroughly explored. The book will be of interest not only to philosophers, but also physicians, lawyers, policy makers, and anyone perplexed by the many difficulties surrounding the unborn.
