In their paper, “Autonomy and the ethics of biological behaviour modification”, Savulescu, Douglas, and Persson discuss the ethics of a technology for improving moral motivation and behaviour that does not yet exist and will most likely never exist. At the heart of their argument sits the imagined case of a “moral technology” that magically prevents people from developing intentions to commit seriously immoral actions. It is not too much of a stretch, then, to characterise their paper as a thought experiment in service of a thought experiment. In order for an argument involving a thought experiment to progress debate in applied ethics three things must be true. First, the thought experiment must accurately represent and illuminate a pressing ethical dilemma. Second – and most obviously – the central claims of the argument regarding the thought experiment must be plausible. Third, it must be possible to apply or develop the arguments established with reference to the thought experiment to the real world cases the experiment is intended to illuminate. In this commentary, I argue that there are serious reasons to question the extent to which their argument meets each of these challenges involved in the use of thought experiments in applied ethics. While Savulescu et al. succeed in showing how behavioural modification might be compatible with freedom and autonomy – and perhaps justifiable even if it were not — in the fantastic case they consider, there is little we can conclude from this about any technology of “moral bioenhancement” in the foreseeable future. Indeed, there is a real danger that their argument will license attempts to manipulate behaviour through drugs and brain implants, which raise profound moral issues that they barely mention.

Should significant enhancement of human capacities using genetic technologies become possible, each generation will have an unprecedented power over the next. I argue that it is implausible to leave decisions about the genetic traits of children entirely up to individuals and that communities will sometimes be justified in intervening to protect the interests of children against their parents. While a number of influential authors have suggested that the primary interest that the community should aim to protect is the child’s right to “an open future”, when we examine closely what we desire for our children, it is clear that sometimes we have good reasons to try to restrict their opportunities to pursue dangerous, corrupting, or meaningless projects. Rather than maximise the openness of their future, then, we should strive to ensure that children have access to sufficient opportunities to make available a reasonable range of valuable life-choices. Importantly, both the assessment of what counts as a reasonable range and our judgements about which forms of life are valuable must inevitably make reference to substantive notions about the nature of human flourishing. A more appropriate formulation, then, of what should be protected by law and/or regulation, is the child’s right to a “decent future”, understood as a future which promises a reasonable range of opportunities to lead a life of human flourishing. I then proceed to highlight the challenge posed by the task of settling upon an idea of what counts as a decent future, for multicultural societies wherein ideas about the standards against which we should evaluate human flourishing are likely to be highly contested.

The willingness of some scientists, futurists … and now philosophers to contemplate—or even actively pursue—their own obsolescence is a source of genuine wonder. Writers such as Hans Moravec,1 Ray Kurzweil2 and Nick Bostrom3 blithely maintain that we will soon be outclassed by our own cybernetic creations as though this were a prospect that could only be celebrated and not feared. In this context, one can only applaud Agar's clearheaded investigation4 of the prospects for creating ‘post-persons’ and his eminently sensible conclusion that there might be good reasons to avoid doing so. His discussion of the significance of the difference between ‘weak’ and ‘strong’ thresholds in moral status and his inductive argument to the existence of higher levels of moral status than humans currently possess constitute significant advances in the philosophical literature on this topic. In these largely sympathetic remarks I will, however, argue both that post-persons are more easily conceived of than Agar suggests and that the threat posed by post-persons, should they eventuate, is greater than Agar allows.Agar's paper needs to be read in the context of Buchanan's discussion5 of the implications of post-personhood to which it is a response. Buchanan's discussion proceeds, for the most part, with reference to an essentially Kantian account of moral status as founded in the ability to engage in practical reasoning or practices of mutual accountability. Talk of ‘animals’, ‘persons’ …

In this paper I describe a future in which persons in advanced old age are cared for entirely by robots and suggest that this would be a dystopia, which we would be well advised to avoid if we can. Paying attention to the objective elements of welfare rather than to people’s happiness reveals the central importance of respect and recognition, which robots cannot provide, to the practice of aged care. A realistic appreciation of the current economics of the aged care sector suggests that the introduction of robots into an aged care setting will most likely threaten rather than enhance these goods. I argue that, as a result, the development of robotics is likely to transform aged care in accordance with a trajectory of development that leads towards this dystopian future even when this is not the intention of the engineers working to develop robots for aged care. While an argument can be made for the use of robots in aged care where the people being cared for have chosen to allow robots in this role, I suggest that over-emphasising this possibility risks rendering it a self-fulfilling prophecy, depriving those being cared for of valuable social recognition, and failing to provide respect for older persons by allowing the options available to them to be shaped by the design choices of others.

This paper uses the fictional case of the ‘Babel fish’ to explore and illustrate the issues involved in the controversy about the use of cochlear implants in prelinguistically deaf children. Analysis of this controversy suggests that the development of genetic tests for deafness poses a serious threat to the continued flourishing of Deaf culture. I argue that the relationships between Deaf and hearing cultures that are revealed and constructed in debates about genetic testing are themselves deserving of ethical evaluation. Making good policy about genetic testing for deafness will require addressing questions in political philosophy and anthropology about the value of culture and also thinking hard about what sorts of experiences and achievements make a human life worthwhile.

The United States Army’s Future Combat Systems Project, which aims to manufacture a “robot army” to be ready for deployment by 2012, is only the latest and most dramatic example of military interest in the use of artificially intelligent systems in modern warfare. This paper considers the ethics of a decision to send artificially intelligent robots into war, by asking who we should hold responsible when an autonomous weapon system is involved in an atrocity of the sort that would normally be described as a war crime. A number of possible loci of responsibility for robot war crimes are canvassed; the persons who designed or programmed the system, the commanding officer who ordered its use, the machine itself. I argue that in fact none of these are ultimately satisfactory. Yet it is a necessary condition for fighting a just war, under the principle of jus in bellum, that someone can be justly held responsible for deaths that occur in the course of the war. As this condition cannot be met in relation to deaths caused by an autonomous weapon system it would therefore be unethical to deploy such systems in warfare.

In this paper I will argue that contemporary non-Aboriginal Australians can collectively be held responsible for past injustices committed against the Aboriginal peoples of this land. An examination of the role played by history in determining the nature of the present reveals both the temporal extension of the Australian community that confronts the question of responsibility for historical injustice and the ways in which we continue to participate in those same injustices. Because existing injustices suffered by indigenous Australians are essentially continuous with the racist history of the invasion of the Australian continent and dispossession of the Australian Aboriginal peoples, we may be held responsible for the wrongs committed in the course of that history.

‘Terraforming’ is hypothetical climatic and geo-physical engineering of other planets on a grand scale, with the aim of turning the so-called ‘barren’ planets in our (or for that matter another) solar system into habitable earth-like eco-systems. Although terraforming sounds like an idea from science fiction (where it indeed has appeared), it has been seriously proposed as a future project for the human race. With such a technology we could colonise the solar system and perhaps eventually others, moulding them in an image of our own making. In this chapter I consider the ethics of terraforming through the lens of an ‘agent-based’ virtue ethics. I argue that advocacy of - and any attempt at - terraforming is likely to demonstrate two significant character flaws in agents: an insensitivity to beauty; and, hubris, an excessive pride or faith in our own abilities in the course of transcending the proper limits of human activities.

In so far as long-range tele-operated weapons, such as the United States’ Predator and Reaper drones, allow their operators to fight wars in what appears to be complete safety, thousands of kilometres removed from those whom they target and kill, it is unclear whether drone operators either require courage or have the opportunity to develop or exercise it. This chapter investigates the implications of the development of tele-operated warfare for the extent to which courage will remain central to the role of the warrior and for the future culture of the armed services in the age of drone warfare.

Ravelingien et al have suggested that early human xenotransplantation trials should be carried out on patients who are in a permanent vegetative state (PVS) and who have previously granted their consent to the use of their bodies in such research in the event of their cortical death. Unfortunately, their philosophical defence of this suggestion is unsatisfactory in its current formulation, as it equivocates on the key question of the status of patients who are in a PVS. The solution proposed by them rests on the idea that it should be up to people themselves to determine when they should be treated as dead. Yet the authors clearly believe (and state) that patients who are in a PVS are in fact dead. Finally, given the public good that their proposal is intended to achieve, the moral importance they place on the consent of a person to the use of his or her body in research is ultimately only defensible in so far as this consent represents the wishes of a living person. It is thus only a gentle caricature of their position to suggest that according to their account, consent to participation in xenotransplantation research is a “right of the living dead”. The equivocation by Ravelingien et al on the question of whether these people are living or dead means that they avoid confronting the implications of their argument. The solution proposed by Ravelingien et al to the problem of how we should proceed with xenotransplantation research is therefore not as neat as it first seems to be

Disability activists influenced by queer theory and advocates of “human enhancement” have each disputed the idea that what is “normal” is normatively significant, which currently plays a key role in the regulation of pre-implantation genetic diagnosis (PGD). Previously, I have argued that the only way to avoid the implication that parents have strong reasons to select children of one sex (most plausibly, female) over the other is to affirm the moral significance of sexually dimorphic human biological norms. After outlining the logic that generates this conclusion, I investigate the extent to which it might also facilitate an alternative, progressive, opening up of the notion of the normal and of the criteria against which we should evaluate the relative merits of different forms of embodiment. This paper therefore investigates the implications of ideas derived from queer theory for the future of PGD and of PGD for the future of queerness

Arming uninhabited vehicles is an increasing trend. Widespread deployment can bring dangers for arms-control agreements and international humanitarian law. Armed UVs can destabilise the situation between potential opponents. Smaller systems can be used for terrorism. Using a systematic definition existing international regulation of armed UVs in the fields of arms control, export control and transparency measures is reviewed; these partly include armed UVs, but leave large gaps. For preventive arms control a general prohibition of armed UVs would be best. If that is unattainable, several measures should be taken. An explicit prohibition of autonomous attack, that is without a human decision, should be added to IHL. Concerning armed UVs remotely controlled by a human soldier, recommendations differ according to type or mission. New kinds of uninhabited nuclear-weapon carriers should be banned. Space weapons should be prohibited in general. UVs smaller than 0.2–0.5 m should be banned. Bigger remotely controlled armed UVs not equipped with weapons of mass destruction should be subject to numerical limitations in various categories. For these the Treaty on Conventional Armed Forces in Europe is an important precedent.

Since the 1980s, a number of medical researchers have suggested that in the future it might be possible for men to become pregnant. Given the role played by the right to reproductive liberty in other debates about reproductive technologies, it will be extremely difficult to deny that this right extends to include male pregnancy. However, this constitutes a reductio ad absurdum of the idea of reproductive liberty. One therefore would be well advised to look again at the extent of this purported right in other contexts in which it is deployed.

The risk posed to the community by possible xenozoonosis after xenotransplantation suggests that some form of 'community consent' is required before whole organ animal-to-human xenotransplantation should take place. I argue that this requirement places greater obstacles in the path of ethical xenotransplantation than has previously been recognised. The relevant community is global and there are no existing institutions with democratic credentials sufficient to establish this consent. The distribution of the risks and benefits from xenotransplantation also means that consent is unlikely to be forthcoming. Proceeding on the basis of hypothetical consent to a package of global health measures that includes xenotransplantation, as Rothblatt has recently advocated, is more problematic than she acknowledges. Given that it may place the lives of citizens of poor nations at risk to benefit the citizens of wealthy nations, xenotransplantation raises significant questions of international justice.

This chapter will sketch a political critique of recent arguments for human enhancement. While on paper it may be possible to sketch out visions of a world in which the pursuit of genetic enhancement of human beings does not lead to a renewed interest in racial hygiene and widespread violations of human rights, the political assumptions one must make in order to hold that this is possible in the real world are – I will argue – excessively optimistic. In reality, the pursuit of human enhancement is all-too-likely to lead us back to something that looks very much like the old eugenics wherein the state is, as a matter of routine, licensing who is allowed to have children and what sort of children they are allowed to have, and thus infringing the reproductive liberty of parents. Similarly, the notion that states will confine the use of technologies of genetics enhancement to the promotion of the welfare of those who are “enhanced” and will resist the temptation to engineer some for the benefits of others also relies on a number of dubious assumptions about the political cultures of the societies in which genetic technologies are likely to be used. A more realistic politics should lead us to be much more cautious about defending the “rights” of parents to enhance their children.

This paper attempts some predictions about the social consequences of nanotechnology and the ethical issues they raise. I set out four features of nanotechnology that are likely to be important in determining its impact and argue that nanotechnology will have significant social impacts in—at least—the areas of health and medicine, the balance of power between citizens and governments, and the balance of power between citizens and corporations. More importantly, responding to the challenge of nanotechnology will require confronting “philosophical” questions about the sort of society we wish to create and the role that technology might play in creating it. This in turn will require developing institutions and processes that allow the public to wield real power in relation to technological trajectories. My ultimate contention is that the immediate task established by the likely social impacts of nanotechnology is not so much to develop an ethics of nanotechnology as to facilitate an ethical conversation about nanotechnology.

Since the first sex reassignment operations were performed, individual sex has come to be, to some extent at least, a technological artifact. The existence of sperm sorting technology, and of prenatal determination of fetal sex via ultrasound along with the option of termination, means that we now have the power to choose the sex of our children. An influential contemporary line of thought about medical ethics suggests that we should use technology to serve the welfare of individuals and to remove limitations on the opportunities available to them. I argue that, if these are our goals, we may do well to move towards a “post sex” humanity. Until we have the technology to produce genuine hermaphrodites, the most efficient way to do this is to use sex selection technology to ensure that only girl children are born. There are significant restrictions on the opportunities available to men, around gestation, childbirth, and breast-feeding, which will be extremely difficult to overcome via social or technological mechanisms for the foreseeable future. Women also have longer life expectancies than men. Girl babies therefore have a significantly more “open” future than boy babies. Resisting the conclusion that we should ensure that all children are born the same sex will require insisting that sexual difference is natural to human beings and that we should not use technology to reshape humanity beyond certain natural limits. The real concern of my paper, then, is the moral significance of the idea of a normal human body in modern medicine

The argument of Julian Savulescu’s 2001 paper, “Procreative Beneficence: Why We Should Select the Best Children” is flawed in a number of respects. Savulescu confuses reasons with obligations and equivocates between the claim that parents have some reason to want the best for their children and the more radical claim that they are morally obligated to attempt to produce the best child possible. Savulescu offers a prima facie implausible account of parental obligation, as even the best parents typically fail to do everything they think would be best for their children let alone everything that is in fact best for their children. The profound philosophical difficulties which beset the attempt to formulate a plausible account of the best human life constitute a further independent reason to resile from Savulescu’s conclusion. Savulescu’s argument also requires parents to become complicit with racist and homophobic oppression, which is yet another reason to reject it. Removing the equivocation from Savulescu’s argument allows us to see that the assertion of an obligation to choose the “best child” has much more in common with the “old” eugenics than Savulescu acknowledges

ABSTRACTJesse Kirkpatrick's ‘Drones and the Martial Virtue Courage’ constitutes the most thorough attempt to date to show that the operators of remotely piloted aircraft can display martial courage and therefore that it may sometimes be appropriate to award them military honours. I argue that while Kirkpatrick's account usefully draws our attention to the risks faced by drone operators and to the possibility that courage may be required to face these risks, he is much less successful in establishing that operators are capable of cultivating and displaying martial courage. The risks that drone operators face are also faced by members of other professions who are very far from being ‘warriors’

When doubts were first raised about the veracity of the dramatic advances in stem cell research announced by Professor Hwang Woo-Suk, a significant minority response was to question the qualifications of journalists to investigate the matter. In this paper I examine the contemporary relationships between science, scientists, the public, and the media. In the modern context the progress of science often relies on the media to mobilise public support for research and also for the purpose of communication within the scientific community. As a result, attempts to counterpose "science" and "the media" should be treated with some caution. I argue that because of the essential role played by ethics in good science, journalists may in fact sometimes be well placed to investigate scientists. At the conclusion of my paper I draw out some of the implications of my analysis for the ethics of investigative journalism directed towards scientific research.

I argue that the existence of sexual dimorphism poses a profound challenge to those philosophers who wish to deny the moral significance of the idea of ‘normal human capacities’ in debates about the ethics of human enhancement. The biological sex of a child will make a much greater difference to their life prospects than many of the genetic variations that the philosophical and bioethical literature has previously been concerned with. It seems, then, that bioethicists should have something to say about the choice between a male and a female embryo. Either, 1) parents have reason to choose boys over girls; (2) parents have reason to choose girls over boys; or, (3) parents have neither reason to choose girls over boys nor reason to choose boys over girls. Embracing either of the first two alternatives has strongly counterintuitive – and arguably morally repugnant – consequences. To motivate the third option we must either make reference to the idea of ‘normal human capacities’ or argue that parents should consider the interests of society when thinking about what sort of children they should bring into the world – an implication that should be extremely controversial in debates about the ‘new eugenics’. I conclude, then, that the idea of ‘normal human capacities’ is properly crucial to reasoning about the ethics of shaping future persons

The cochlear implant controversy involves questions about the nature of disability and the definition of “normal” bodies; it also raises arguments about the nature and significance of culture and the rights of minority cultures. I defend the claim that there might be such a thing as “Deaf culture” and then examine how two different understandings of the role of culture in the lives of individuals can lead to different conclusions about the rights of Deaf parents in relation to their children, and about the ethics of public funding for research on cochlear implants. An argument asserting the rights of minority cultures to equal respect and consideration within a multicultural society, informed by communitarian political philosophy, offers the best prospect for the defence of the unique culture(s) of the Deaf.
