The biophilosophic justification for the idea that “brain death” is death needs to support two claims: that what dies in human death is a human organism, not merely a psychological entity distinct from it; that total brain failure signifies the end of the human organism as a whole. Defenders of brain death typically assume without argument that the first claim is true and argue for the second by defending the “integrative unity” rationale. Yet the integrative unity rationale has fallen on (...) hard times. In this article, I give reasons for why we should think of ourselves as organisms, and why the “fundamental work” rationale put forward by the 2008 President’s Council is better than the integrative unity rationale, despite persistent objections to it.

In this article, I present a novel argument against abortion. In short, what makes it wrong to kill someone is that they are a counterfactual person; counterfactual persons are individuals such that, were they not killed, they would have been persons. My view accommodates two intuitions which many views concerning the wrongness of killing fail to account for: embryo rescue cases and the impermissibility of infanticide. The view avoids embryo rescue cases because embryos in the rescue scenarios are not counterfactual (...) people: they are not counterfactual people because it is false to say that, were they not killed, they would have been persons. As a result, it does not follow from my account that there is a prohibition against allowing embryos to die. On the other hand, infants are counterfactual people: an infant is an individual such that, were she not killed, she would have been a person. (shrink) | |
Alongside a revival of interest in Thomism in philosophy, scholars have realised its relevance when addressing certain contemporary issues in bioethics. This book offers a rigorous interpretation of Aquinas's metaphysics and ethical thought, and highlights its significance to questions in bioethics. Jason T. Eberl applies Aquinas’s views on the seminal topics of human nature and morality to key questions in bioethics at the margins of human life – questions which are currently contested in the academia, politics and the media such (...) as: When does a human person’s life begin? How should we define and clinically determine a person’s death? Is abortion ever morally permissible? How should we resolve the conflict between the potential benefits of embryonic stem cell research and the lives of human embryos? Does cloning involve a misuse of human ingenuity and technology? What forms of treatment are appropriate for irreversibly comatose patients? How should we care for patients who experience unbearable suffering as they approach the end of life? _Thomistic Principles and Bioethics_ presents a significant philosophical viewpoint which will motivate further dialogue amongst religious and secular arenas of inquiry concerning such complex issues of both individual and public concern.

Recent scientific advances have indicated that it may be technically feasible to sustain human embryos in vitro beyond 14 days. Research beyond this stage is currently restricted by a guideline known as the 14-day rule. Since the advances in embryo culturing there have been calls to extend the current limit. Much of the current debate concerning an extension has regarded the 14-day rule as a political compromise and has, therefore, focused on policy concerns rather than assessing the philosophical foundations of (...) the limit. While there are relevant political considerations, I maintain that the success of extension arguments will ultimately depend on the strength of the justifications supporting the current 14-day limit. I argue that the strongest and most prevalent justifications for the 14-day rule—an appeal to individuation and neural development—do not provide adequate support for the limit of 14 days. I instead suggest that an alternative justification based on sentience would constitute a more defensible basis for embryo protection and that a consideration of such grounds appears to support an amendment to the current limit, rather than the retention of it. While these conclusions do not establish conclusively that the current limit should be extended; they do suggest that an extension may be warranted and permissible. As such, this paper offers grounds on which a reassessment of the 14-day rule may be justified. (shrink) | |
Setting aside some complexities, Koplin and Wilkinson1 argue: 1. Moral status is uncertain if there is a non-zero chance that an entity has, or would develop, full moral status. 2. If its moral status is uncertain, then moral caution is warranted towards that entity. 3. The moral status of both non-chimeric pigs and human-pig chimaeras is uncertain. (Conclusion 1) Therefore, consistency demands that moral caution is warranted towards both non-chimeric pigs and human-pig chimaeras. 4. The commonly held view is that (...) moral caution is warranted towards human-pig chimaeras, but not non-chimeric pigs. (Conclusion 2) Therefore, the commonly held view is inconsistent. This is a valid argument. The authors claim that the inconsistency they expose in conclusion 2 could be resolved in favour of either commonly held view, or by revising both to equivalency. However, it is clear from conclusion 1, and the paper more generally, that the authors are arguing for moral caution to be applied to the treatment of pigs of both types. I will focus on evaluating premises 1 and 2, and the generalisability of the argument in light of this. In doing so, I will attempt to show that the argument has implausible logical implications, and that the moral caution warranted towards human-pig chimaeras of uncertain moral status does not require confidence that they lack full moral status, as the authors claim. According to premise 1, if an entity might currently have moral …. (shrink) | |
Some form of potential or "capacity" is often seen as evidence of human moral status. Opinions differ as to whether the potential of the embryo should be regarded as such evidence. In this paper, I discuss some common arguments against regarding the embryo's potential as a sign of human status, together with some less common arguments in favour of regarding the embryo's potential in this way. | |
This study is a contribution to the bioethical debate about new and possibly emerging reproductive technologies. Its point of departure is the intuition, which many people seem to share, that using such technologies to select non-disease traits – like sex and emotional stability - in yet unborn children is morally problematic, at least more so than using the technologies to avoid giving birth to children with severe genetic diseases, or attempting to shape the non-disease traits of already existing children by (...) environmental means, like education. The study employs philosophical analysis for the purpose of making this intuition intelligible and judging whether it is justified. Different ways in which the moral problems posed by reproductive technologies are often framed in bioethical debates are criticised as inadequate for this task. In particular, it is argued that the intuition cannot fully be made sense of in terms of harm to the children that such technologies help create. The study attempts to elaborate an alternative to that broadly consequentialist approach, by drawing on Martin Heidegger’s philosophy of technology, Hans Jonas’s ethics, and Aristotle’s practical philosophy, as it has been received and developed in the hermeneutical tradition. It is suggested that reproductive choices, unlike decisions for already born children, are characterised by a peculiar one-sidedness: the future child appears to the parents as something wholly theirs to decide about, not as a concrete other with whom they must interact in a responsive and attuned way. This is problematic because it means that such choices cannot call upon the particularised moral understanding only gained in interpersonal encounters. In particular, it makes them easily shaped by various tendencies, to which parents are always susceptible, to relate to children in instrumentalising ways, and at risk of reinforcing such tendencies. However, this does not mean that all uses of reproductive technologies are equally troubling. When selecting against severe disease the parents can rely on a widely shared illness experience to escape the dangers that one-sidedness involves. It is concluded that the intuition under discussion, thus explicated and in some ways qualified, makes sense morally. (shrink) | |
This paper explores how current United States policies for funding nonreproductive cloning are justified and argues against that justification. I show that a common conceptual framework underlies the national prohibition on the use of public funds for cloning research, which I call the simple argument. This argument rests on two premises: that research harming human embryos is unethical and that embryos produced via fertilization are identical to those produced via cloning. In response to the simple argument, I challenge the latter (...) premise. I demonstrate there are important ontological differences between human embryos (produced via fertilization) and clone embryos (produced via cloning). After considering the implications my argument has for the morality of publicly funding cloning for potential therapeutic purposes and potential responses to my position, I conclude that such funding is not only ethically permissible, but also humane national policy.

The debate about the moral status of the embryo has gained new impetus because of the advances in reproductive technology that have made early human embryo experimentation a possibility, and because of the public concern that this arouses. Several philosophical arguments claiming that fertilisation is the event that accords moral status to the embryo were initially formulated in the context of the abortion debate. Were they formulated with sufficient precision to account for the scientific facts as we now understand them? (...) Or do these arguments need modification? Aspects of three arguments for moral status being acquired at fertilisation are examined in relation to current scientific knowledge, highlighting the reasons why such arguments, at present, seem to provide an inadequate basis for the determination of moral status.

Recent advancements in developmental biology enable the creation of embryo-like structures from human stem cells, which we refer to as human embryo-like structures (hELS). These structures provide promising tools to complement—and perhaps ultimately replace—the use of human embryos in clinical and fundamental research. But what if these hELS—when further improved—also have a claim to moral status? What would that imply for their research use? In this paper, we explore these questions in relation to the traditional answer as to why human (...) embryos should be given greater protection than other (non-)human cells: the so-called Argument from Potential (AfP). According to the AfP, human embryos deserve special moral status because they have the unique potential to develop into persons. While some take the development of hELS to challenge the very foundations of the AfP, the ongoing debate suggests that its dismissal would be premature. Since the AfP is a spectrum of views with different moral implications, it does not need to imply that research with human embryos or hELS that (may) have ‘active’ potential should be completely off-limits. However, the problem with determining active potential in hELS is that this depends on development passing through ‘potentiality switches’ about the precise coordinates of which we are still in the dark. As long as this epistemic uncertainty persists, extending embryo research regulations to research with specific types of hELS would amount to a form of regulative precaution that as such would require further justification.

Medical stem cell research is currently the cause of much moral controversy. Those who would confer the same moral status to embryos as we do to humans consider that harvesting such embryonic cells entails sacrificing embryos. In this paper, the author analyses critically the arguments given for such a perspective. Finally, a theory of moral status is outlined that coherently and plausibly supports the use of embryonic stem cells in therapeutic research. | |
