Bioethics

A guide to the rapidly progressing Age of Biotechnology, Brutes or Angels provides basic information on a wide array of new technologies in the life sciences, along with the ethical issues raised by each. With stem cell research, Dolly the cloned sheep, in vitro fertilization, age retardation, and pharmaceutical mind enhancement, humankind is now faced with decisions that it has never before had to consider. The thoughtfulness, or lack of it, that we bring to those decisions will largely determine the future character of the living world. Brutes or Angels will facilitate informed choice making about the personal use of biotechnologies and the formulation of public policies governing their development and use. Ten biotechnologies that impact humans are considered: stem cell research, embryo selection, human genomics, gene therapies, human reproductive cloning, age retardation, cognition enhancement, the engineering of nonhuman organisms, nanobiology, and synthetic biology. With deft and assured use of metaphors, analogies, diagrams, and photographs, James T. Bradley introduces important biological principles and the basic procedures used in biotechnology. Various ethical issues--personhood, personal identity, privacy, ethnic discrimination, distributive justice, authenticity and human nature, and the significance of mortality in the human life cycle--are presented in a clear and unbiased manner. Personal reflection and group dialogue are encouraged by questions at the end of each chapter, making this book not only a general guide to better informed and nuanced thinking on these complex and challenging topics but also an appropriate text for bioethics courses in university science departments and for adult education classes. Standing at the beginning of the twenty-first century, with burgeoning abilities to enhance and even create life in ways unimaginable just a few decades ago, humans have an awesome responsibility to themselves and other species. Brutes or Angelsinvites us to engage each other in meaningful dialogue by listening, gathering information, formulating thoughtful views, and remaining open to new knowledge and ethical argumentation.

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. This collection advances and enriches our understanding of the ethical issues raised by these technologies and identifies 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.

Colin Farrelly contemplates the various ethical and social quandaries raised by the genetic revolution. Recent biomedical advances such as genetic screening, gene therapy and genome editing might be used to promote equality of opportunity, reproductive freedom, healthy aging, and the prevention and treatment of disease. But these technologies also raise a host of ethical questions: Is the idea of "genetically engineering" humans a morally objectionable form of eugenics? Should parents undergoing IVF be permitted to screen embryos for the sex of their offspring? Would it be ethical to alter the rate at which humans age, greatly increasing longevity at a time when the human population is already at potentially unsustainable levels? Farrelly applies an original virtue ethics framework to assess these and other challenges posed by the genetic revolution. Chapters discuss virtue ethics in relation to eugenics, infectious and chronic disease, evolutionary biology, epigenetics, happiness, reproductive freedom and longevity. This fresh approach creates a roadmap for thinking ethically about technological progress that will be of practical use to ethicists and scientists for years to come. Accessible in tone and compellingly argued, this book is an ideal introduction for students of bioethics, applied ethics, biomedical sciences, and related courses in philosophy and life sciences.

Explores the ethical, legal, and societal issues arising from brain imaging, psychopharmacology, and other new developments in neuroscience.Neuroscience increasingly allows us to explain, predict, and even control aspects of human behavior. The ethical issues that arise from these developments extend beyond the boundaries of conventional bioethics into philosophy of mind, psychology, theology, public policy, and the law. This broader set of concerns is the subject matter of neuroethics. In this book, leading neuroscientist Martha Farah introduces the reader to the key issues of neuroethics, placing them in scientific and cultural context and presenting a carefully chosen set of essays, articles, and excerpts from longer works that explore specific problems in neuroethics from the perspectives of a diverse set of authors. Included are writings by such leading scientists, philosophers, and legal scholars as Carl Elliot, Joshua Greene, Steven Hyman, Peter Kramer, and Elizabeth Phelps. Topics include the ethical dilemmas of cognitive enhancement; issues of personality, memory and identity; the ability of brain imaging to both persuade and reveal; the legal implications of neuroscience; and the many ways in which neuroscience challenges our conception of what it means to be a person.Neuroethics is an essential guide to the most intellectually challenging and socially significant issues at the interface of neuroscience and society. Farah's clear writing and well-chosen readings will be appreciated by scientist and humanist alike, and the inclusion of questions for discussion in each section makes the book suitable for classroom use.
