I defend the argument that if embryo loss in stem cell research is morally problematic, then embryo loss in in vivo conception is similarly morally problematic. According to a recent challenge to this argument, we can distinguish between in vivo embryo loss and the in vitro embryo loss of stem cell research by appealing to the doctrine of double effect. I argue that this challenge fails to show that in vivo embryo loss is a mere unintended side effect while in (...) vitro embryo loss is an intended means and that, even if we refine the challenge by appealing to Michael Bratman's three roles of intention, the distinction is still unwarranted.

It is now 10 years ago that human embryonic stem cell research appeared as a major topic of societal concern following significant scientific breakthroughs.1 2 During these 10 years it has become obvious that stem cell research is embedded in a narrative characterised by hope and hype and that it has created heated moral and political debate. Although it would be tempting to try to deconstruct the importance attributed to hope in this story or to unmask the different instigators active (...) in promoting hype,3–5 the main aim of this editorial is to briefly review the controversies underlying the debate and propose some possible answers to a set of inter-related questions: What are the main disagreements in the stem cell debate? Is there any hope that we can resolve these main disagreements? Has the debate been a fruitful model for future debates about ethically contentious issues in biomedicine, or has it been characterised more by rhetoric than by argument? What kind of ethical debates are most efficient as models for future debates?The two authors agree with regard to the importance of asking these questions, but they disagree about at least some of the answers. Let us start with the questions about the debate and its use as a model for future debates.WHAT KIND OF ETHICAL DEBATE IS MOST EFFICIENT AS A MODEL FOR FUTURE DEBATES?Could it be the case that ethical debates that are characterised by overselling of the potential of the technology are more efficient as models for future debates about ethically contentious issues in biomedicine than more sober and “neutral” debates? The narratives of stem cell research are full of examples of overselling and underselling, and we will suggest that it is precisely for this reason that there is a lot to learn morally from reviewing the narratives. The two main forms of overselling are therapeutic …. (shrink)

The stem cell story is not a simple story but a complex narrative: one that requires careful analysis in order to identify major themes and plots. This paper offers an analysis of the ethics of the clinical application of stem cells and argues that even quite risky therapies can be ethical. These arguments cannot be used to justify all aspects of contemporary stem cell science, including human embryonic stem cell science, which remains theoretical and speculative. It is argued that the (...) homogenisation of stem cell science obscures the distinction between clinical application and experimental laboratory science in a morally problematic way. (shrink)

A number of areas of biology raise questions about what is of value in the natural environment and how we ought to behave towards it: conservation biology, environmental science, and ecology, to name a few. Based on my experience teaching students from these and similar majors, I argue that the field of environmental ethics has much to teach these students. They come to me with pent-up questions and a feeling that more is needed to fully engage in their subjects, and (...) I believe some exposure to environmental ethics can help focus their interests and goals. I identify three primary areas in which environmental ethics can con- tribute to their education. The first is an examination of who (or what) should be considered to be part of our moral community (i.e., the community to whom we owe direct duties). Is it humans only? Or does it include all sentient life? Or all life? Or ecosystems considered holistically? Often, readings implicitly assume one or more of these answers; the goal is to make the student more sensitive to these implicit claims and to get them to think about the different reasons that support them. The second area, related to the first, is the application of the different answers concerning the extent of the ethical community to real environmental issues and problems. Students need to be aware of how the different answers concerning the moral community can imply conflicting answers for how we should act in certain cases and to think about ways to move toward conflict resolution. The third area in which environmental ethics can contribute is a more conceptual one, focusing on central concepts such as biodiversity, sustainability, species, and ecosystems. Exploring and evaluating various meanings of these terms will make students more reflective and thoughtful citizens and biologists, sensitive to the implications that different conceptual choices make.

Human reproductive cloning has become the most palpable example of the globalization of science. Throughout the world, events and conjectures in the media, such as the birth and death in the United Kingdom of the cloned sheep Dolly and projects to clone human beings by Korean scientists, by members of the Canadian-based Raelian cult, and by the Italian physician Antinori in an undisclosed country, have galvanized the political will of individual countries to ban human reproductive cloning.Yet, international attempts to harmonize (...) policies in the area of biomedical ethics and human research, such as the 1997 Council of Europe’s Convention on Human Rights and Biomedicine, and most recently, the United Nations’ efforts to adopt an international convention against human reproductive cloning, have been insufficient to trigger a substantial global policy design process on issues relating to these new technologies.
