Purpose of review The purpose of this review is to present and analyse recent literature on the patterns, trends, and developments of ethical considerations concerning xenotransplantation by appraising normative aspects within a coherent framework. Recent findings Developments within xenotransplantation may soon allow for pig-to-human xenotransplantation to take place. Ethical analysis of xenotransplantation commonly follows an anthropocentric cost–benefit analysis, which may imprecisely measure costs. Xenotransplantation should not merely be approached from an anthropocentric perspective. Rather, the potential risks presented to human and nonhuman donors, recipients, and third parties should all be thoroughly considered. Summary The range of feasible alternatives to xenotransplantation to increase organ supply should be examined before resorting to xenotransplantation because of the moral distinction between imposing certain risks on others before, or after, alternative solutions have been exhausted.
Synthetic biology is a cutting-edge area of research that holds the promise of unprecedented health benefits. However, in tandem with these large prospective benefits, synthetic biology projects entail a risk of catastrophic consequences whose severity may exceed that of most ordinary human undertakings. This is due to the peculiar nature of synthetic biology as a 'threshold technology' which opens doors to opportunities and applications that are essentially unpredictable. Fears about these potentially unstoppable consequences have led to declarations from civil society groups calling for the use of a precautionary principle to regulate the field. Moreover, the principle is prevalent in law and international agreements. Despite widespread political recognition of a need for caution, the precautionary principle has been extensively criticized as a guide for regulatory policy. We examine a central objection to the principle: that its application entails crippling inaction and incoherence, since whatever action one takes there is always a chance that some highly improbable cataclysm will occur. In response to this difficulty, which we call the 'precautionary paradox,' we outline a deliberative means for arriving at threshold of probability below which potential dangers can be disregarded. In addition, we describe a Bayesian mechanism with which to assign probabilities to harmful outcomes. We argue that these steps resolve the paradox. The rehabilitated PP can thus provide a viable policy option to confront the uncharted waters of synthetic biology research.
Applied ethics is home to numerous productive subfields such as procreative ethics, intergenerational ethics and environmental ethics. By contrast, there is far less ethical work on ageing, and there is no boundary work that attempts to set the scope for ‘ageing ethics’ or the ‘ethics of ageing’. Yet ageing is a fundamental aspect of life; arguably even more fundamental and ubiquitous than procreation. To remedy this situation, I examine conceptions of what the ethics of ageing might mean and argue that these conceptions fail to capture the requirements of the desired subfield. The key reasons for this are, first, that they view ageing as something that happens only when one is old, thereby ignoring the fact that ageing is a process to which we are all subject, and second that the ageing person is treated as an object in ethical discourse rather than as its subject. In response to these shortcomings I put forward a better conception, one which places the ageing person at the centre of ethical analysis, has relevance not just for the elderly and provides a rich yet workable scope. While clarifying and justifying the conceptual boundaries of the subfield, the proposed scope pleasingly broadens the ethics of ageing beyond common negative associations with ageing.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
