The worst possible way to resolve this issue is to leave it up to individual choice. There is no known social good coming from the conquest of death (Bailey, 1999). - Daniel Callahan Dramatically extending the human lifespan seems increasingly possible. Many bioethicists object that life-extension will have Malthusian consequences as new Methuselahs accumulate, generation by generation. I argue for a Life-Years Response to the Malthusian Objection. If even a minority of each generation chooses life-extension, denying it to them deprives (...) them of many years of extra life, and their total extra life-years are likely to exceed the total life-years of a majority who do not want life-extension. This is a greater harm to those who want extended life than the Malthusian harms to those who refuse extended life, both because losing an extra year of life is worse than enduring a year of Malthusian conditions, and because the would-be Methuselahs have more life-years at stake. Therefore, even if life-extension seems likely to cause severe overcrowding and resource shortages, that threat is not sufficient to justify society in restricting the development or availability of life-extension.

The prospect of human genetic enhancement requires an institutional response, and probably the creation of new institutions. The governance of genetic enhancement technologies, moreover, needs to be global in scope. In this article, I analyze the debate on the global governance of human genetic enhancement. I begin by offering a philosophical justification for the need to adopt a global framework for governance of technologies that would facilitate the improvement of non-pathological genetic traits. I then summarize the main concrete proposals that (...) have recently emerged to govern genome editing at the global level. Finally, I develop some impediments that limit the impetus for global governance of genetic enhancement. (shrink)

New scientific advances have created previously unheard of possibilities for enhancing combatants' performance. Future war fighters may be smarter, stronger, and braver than ever before. If these technologies are safe, is there any reason to reject their use? In this article, I argue that the use of enhancements is constrained by the importance of maintaining the moral responsibility of military personnel. This is crucial for two reasons: the military's ethical commitments require military personnel to be morally responsible agents, and moral (...) responsibility is necessary for integrity and the moral emotions of guilt and remorse, both of which are important for moral growth and psychological well-being. Enhancements that undermined combatants' moral responsibility would therefore undermine the military's moral standing and would harm combatants' well-being. A genuine commitment to maintaining the military's ethical standards and the well-being of combatants therefore requires a careful analysis of performance-enhancing technologies before they are implemented.

Many opinions and ideas about aging exist. Biological theories have taken hold of the popular and scientific imagination as potential answers to a “cure” for aging. However, it is not clear what exactly is being cured or whether aging could be classified as a disease. Some scientists are convinced that aging will be biologically alterable and that the human lifespan will be vastly extendable. Other investigators believe that aging is an elusive target that may only be “statistically” manipulatable through a (...) better understanding of the operational principles of systems situated within complex environments. Not only is there confusion over definitions but also as to the safety of any potential intervention. Curing cell death, for example, may lead to cell cancer. The search for a cure for aging is not a clearly beneficial endeavour. This paper will first, describe contemporary ideas about aging processes and second, describe several current life extension technologies. Third, it analyses these theories and technologies, focusing on two representative and differing scientific points of view. The paper also considers the public health dilemma that arises from life extension research and examines two issues, risk/benefit ratio and informed consent, that are key to developing ethical guidelines for life extension technologies.

The range of opportunities people enjoy in life largely depends on social, biological, and genetic factors for which individuals are not responsible. Philosophical debates about equality of opportunities have focussed mainly on addressing social determinants of inequalities. However, the introduction of human bioenhancement should make us reconsider what our commitment to equality entails. We propose a way of improving morally relevant equality that is centred on what we consider a fair distribution of bioenhancements. In the first part, we identify three (...) main positions in the debate on bioenhancement and equality, and we show how each of them fails to meet the demands of a serious commitment to equality. In the second part, we formulate a new proposal that we think better promotes equality of opportunities: people from disadvantaged socio-economic backgrounds should be given access to bioenhancements while people from privileged socio-economic background should be prohibited from using them. We argue that those who are concerned about the inequality implications of bioenhancement should embrace this solution, rather than reject bioenhancement. (shrink)

In this article, I argue that lawmakers must abandon their previous reluctance to engage with questions of personal identity (PI). While frequently seen as an esoteric subject, of limited interest outside of academic philosophy departments, I attempt to show that, in fact, assumptions about PI—and its durability in the face of certain psychological or genetic changes—underpin many current legal rules. This is most perhaps obviously exemplified with regard to reproductive technologies. Yet the Parfitian challenge to identify a victim of ‘bad’ (...) reproductive choices has been largely overlooked in framing legislative responses to such technologies. Furthermore, I argue, it is not only with regard to emerging technologies that questionable assumptions about PI play a role; legal responses to questions about the attribution of criminal responsibility, and about the treatment of demented or brain-injured people, necessitate a frank engagement with such questions. It may be, however, that a multi-faceted approach to PI, which takes account of genetic, psychological and social factors—will prove a better fit for the myriad needs of the legal system than any sort of ‘unified theory of identity’.

In the newly emerging debates about genetics and justice three distinct principles have begun to emerge concerning what the distributive aim of genetic interventions should be. These principles are: genetic equality, a genetic decent minimum, and the genetic difference principle. In this paper, I examine the rationale of each of these principles and argue that genetic equality and a genetic decent minimum are ill-equipped to tackle what I call the currency problem and the problem of weight. The genetic difference principle (...) is the most promising of the three principles and I develop this principle so that it takes seriously the concerns of just health care and distributive justice in general. Given the strains on public funds for other important social programmes, the costs of pursuing genetic interventions and the nature of genetic interventions, I conclude that a more lax interpretation of the genetic difference principle is appropriate. This interpretation stipulates that genetic inequalities should be arranged so that they are to the greatest reasonable benefit of the least advantaged. Such a proposal is consistent with prioritarianism and provides some practical guidance for non-ideal societies–that is, societies that do not have the endless amount of resources needed to satisfy every requirement of justice.

It is sometimes claimed that those who succeed with the aid of enhancement technologies deserve the rewards associated with their success less, other things being equal, than those who succeed without the aid of such technologies. This claim captures some widely held intuitions, has been implicitly endorsed by participants in social–psychological research and helps to undergird some otherwise puzzling philosophical objections to the use of enhancement technologies. I consider whether it can be provided with a rational basis. I examine three (...) arguments that might be offered in its favour and argue that each either shows only that enhancements undermine desert in special circumstances or succeeds only under assumptions that deprive the appeal to desert of much of its dialectic interest.

What justifies our holding a person morally responsible for some past action? Why am I justified in having a special prudential concern for some future persons and not others? Why do many of us think that maximizing the good within a single life is perfectly acceptable, but maximizing the good across lives is wrong? In these and other normative questions, it looks like any answer we come up with will have to make an essential reference to personal identity. So, for (...) instance, it seems we are justified in holding X responsible for some past action only if X is identical to the person who performed that action. Further, it seems I am justified in my special concern for some future person only if he will be me. Finally, many of us think that while maximization within a life affects only one person, a metaphysical unity, maximization across lives affects many different, metaphysically distinct, persons, and so the latter is wrong insofar as it ignores this fundamental separateness of persons.
