In 1970 Van Rensselaer Potter was the first to use the term "bioethics" in a publication to advocate the development of a new discipline to address the basic problems of human flourishing. This article analyzes Potter's notion of bioethics in order to understand its origins, sources, and substance. In early publications, Potter conceptualized bioethics as a bridge: between present and future, nature and culture, science and values, and finally between humankind and nature. In later publications, disappointed by a predominant focus (...) on individual and medical issues, and with a wish to underscore the need for a broader perspective, Potter introduced the new term "global bioethics," meant to transcend ethics specialties and integrate them into a new interdisciplinary endeavor to address global problems. A growing interest in global bioethics today means that Potter's original insights are more timely than ever. (shrink)

At the end of a thoughtful article on the future of nuclear war, Wiesner and York concluded that: "Both sides in the arms race are... confronted by the dilemma of steadily increasing military power and steadily decreasing national security. It is our considered professional judgment that this dilemma has no technical solution. If the great powers continue to look for solutions in the area of science and technology only, the result will be to worsen the situation.".

Climate change has substantial impacts on public health and safety, disease risks and the provision of health care, with the poor being particularly disadvantaged. Management of the associated health risks and changing health service requirements requires adequate responses at local levels. Health-care providers are central to these responses. While climate change raises ethical questions about its causes, impacts and social justice, medicine and bioethics typically focus on individual patients and research participants rather than these broader issues. We broaden this focus (...) by examining awareness among health-care providers in the Caribbean region, where geographic and socioeconomic features pose particular vulnerabilities to climate change. In focus groups, Caribbean providers described rises in mosquito-borne, flood-related, heat-related, respiratory and mental illnesses, and attributed these to local impacts of climate change. Their discussions showed that the significance of these impacts differs in different Caribbean nations, raising policy and social justice questions. Bioethics and public health ethics are situated to frame, inform and initiate public and policy dialog about values and scientific evidence associated with climate change. We urge readers to initiate such dialog within their own institutions about the context-dependent nature of the burdens of climate change, and values and policies that permit it to worsen. (shrink)

In this paper I argue that bioethics is in crisis and that it will not have a future unless it begins to embrace a more Socratic approach to its leading assumptions. The absence of a critical and sceptical spirit has resulted in little more than a dominant ideology. I focus on three key issues. First, that too often bioethics collapses into medical ethics. Second, that medical ethics itself is beset by a lack of self-reflection that I characterize here as a (...) commitment to three dogmas. Third, I offer a more positive perspective by suggesting how bioethics may benefit from looking towards public health ethics as a new source of inspiration and direction. (shrink)
