Many subscribe to an Ethic of Life, an ethical perspective on which all living things deserve some level of moral concern. Within philosophy, the Ethic of Life has been clarified, developed, and rigorously defended; yet it has also found its harshest critics. Between biocentrists, those that endorse the Ethic of Life, and those that accept a more restricted view of moral status, the debate has reached a standstill, with few new resources for shifting or complicating it. In The Death of the Ethic of Life, John Basl seeks to end this comfortable stalemate by emphasizing a simple truth: the well-being of non-sentient beings, such as plants, species, and ecosystems, is morally significant only to the extent that it matters to sentient beings. Basl first develops a version of The Ethic of Life that best meets traditional challenges: the Ethic, if it is to survive criticism, must be able to explain how it is that all living things have a welfare or a good of their own. The best hope of offering such an explanation is to ground that welfare in teleology or goal-directedness, and then to ground that goal-directedness in the workings of natural selection. While a naturalistic account of teleology is crucial to defending an Ethic of Life, it is also its downfall. This Ethic ultimately entails that not only are ecosystems and collectives morally considerable, but so, too, are artifacts: everything from can openers to computers. Basl shows that evaluation of the resources for distinguishing artifacts from organisms forces us to abandon, for good, the Ethic of Life. The Death of the Ethic of Life provides not only a new answer to a fundamental question in environmental ethics, but a new way to conceive of fundamental concepts and issues in debates over who or what matters from the moral point of view, with wide-ranging implications in the philosophy of technology and bioethics.

A range of views on the morality of synthetic biology and its place in public policy and political discourse. Synthetic biology, which aims to design and build organisms that serve human needs, has potential applications that range from producing biofuels to programming human behavior. The emergence of this new form of biotechnology, however, raises a variety of ethical questions-first and foremost, whether synthetic biology is intrinsically troubling in moral terms. Is it an egregious example of scientists "playing God"? Synthetic Biology and Morality takes on this threshold ethical question, as well as others that follow, offering a range of philosophical and political perspectives on the power of synthetic biology. The contributors consider the basic question of the ethics of making new organisms, with essays that lay out the conceptual terrain and offer opposing views of the intrinsic moral concerns; discuss the possibility that synthetic organisms are inherently valuable; and address whether, and how, moral objections to synthetic biology could be relevant to policy making and political discourse. Variations of these questions have been raised before, in debates over other biotechnologies, but, as this book shows, they take on novel and illuminating form when considered in the context of synthetic biology.

Advances in our scientific understanding and technological power in recent decades have dramatically amplified our capacity to intentionally manipulate complex ecological and biological systems. An implication of this is that biological and ecological problems are increasingly understood and approached from an engineering perspective. In environmental contexts, this is exemplified in the pursuits of geoengineering, designer ecosystems, and conservation cloning. In human health contexts, it is exemplified in the development of synthetic biology, bionanotechnology, and human enhancement technologies. Designer Biology: The Ethics of Intensively Engineering Biological and Ecological Systems consists of thirteen chapters (twelve of them original to the collection) that address the ethical issues raised by technological intervention and design across a broad range of biological and ecological systems. Among the technologies addressed are geoengineering, human enhancement, sex selection, genetic modification, and synthetic biology. The aim of the collection is to advance and enrich our understanding of the ethical issues raised by these technologies, as well as to identify general lessons about the ethics of engineering complex biological and ecological systems that can be applied as new technologies and practices emerge. The insights that emerge will be especially valuable to students and scholars of environmental ethics, bioethics, or technology ethics.
