A crucially important part of the biosphere – the virosphere – is too often overlooked. Inclusion of the virosphere into the global picture of protein structure space reveals that 63 protein domain superfamilies in viruses do not have any structural and evolutionary relatives in modern cellular organisms. More than half of these have functions which are not virus‐specific and thus might be a source of new folds and functions for cellular life. The number of viruses on the planet exceeds that (...) of cells by an order of magnitude and viruses evolve up to six orders of magnitude faster. As a result, cellular species are subject to a constitutive ‘flow‐through’ of new viral genetic material. Due to this and the relaxed evolutionary constraints in viruses, the transfer of domains between host‐to‐virus could be a mechanism for accelerated protein evolution. The virosphere could be an engine for the genesis of protein structures, and may even have been so before the last universal common ancestor of cellular life. (shrink)

Recent sequencing of the metazoan Oikopleura dioica genome has provided important insights, which challenges the current understanding of eukaryotic genome evolution. Many genomic features of O. dioica show deviation from the commonly observed trends in other eukaryotic genomes. For instance, O. dioica has a rapidly evolving, highly compact genome with a divergent intron‐exon organization. Additionally, O. dioica lacks the minor spliceosome and key DNA repair pathway genes. Even with a compact genome, O. dioica contains tandem repeats, comparable to other eukaryotes, (...) and shows lineage‐specific expansion of certain protein domains. Here, we review its genomic features in the context of current knowledge, discuss implications for contemporary biology and identify areas for further research. Analysis of the O. dioica genome suggests that non‐adaptive forces such as elevated mutation rates might influence the evolution of genome architecture. The knowledge of unique genomic features and splicing mechanisms in O. dioica may be exploited for synthetic biology applications, such as generation of orthogonal splicing systems. (shrink)

Mandatory vaccination, including for COVID-19, can be ethically justified if the threat to public health is grave, the confidence in safety and effectiveness is high, the expected utility of mandatory vaccination is greater than the alternatives, and the penalties or costs for non-compliance are proportionate. I describe an algorithm for justified mandatory vaccination. Penalties or costs could include withholding of benefits, imposition of fines, provision of community service or loss of freedoms. I argue that under conditions of risk or perceived (...) risk of a novel vaccination, a system of payment for risk in vaccination may be superior. I defend a payment model against various objections, including that it constitutes coercion and undermines solidarity. I argue that payment can be in cash or in kind, and opportunity for altruistic vaccinations can be preserved by offering people who have been vaccinated the opportunity to donate any cash payment back to the health service.

There are no egalitarians in a pandemic. The scale of the challenge for health systems and public policy means that there is an ineluctable need to prioritize the needs of the many. It is impossible to treat all citizens equally, and a failure to carefully consider the consequences of actions could lead to massive preventable loss of life. In a pandemic there is a strong ethical need to consider how to do most good overall. Utilitarianism is an influential moral theory (...) that states that the right action is the action that is expected to produce the greatest good. It offers clear operationalizable principles. In this paper we provide a summary of how utilitarianism could inform two challenging questions that have been important in the early phase of the pandemic: (a) Triage: which patients should receive access to a ventilator if there is overwhelming demand outstripping supply? (b) Lockdown: how should countries decide when to implement stringent social restrictions, balancing preventing deaths from COVID‐19 with causing deaths and reductions in well‐being from other causes? Our aim is not to argue that utilitarianism is the only relevant ethical theory, or in favour of a purely utilitarian approach. However, clearly considering which options will do the most good overall will help societies identify and consider the necessary cost of other values. Societies may choose either to embrace or not to embrace the utilitarian course, but with a clear understanding of the values involved and the price they are willing to pay. (shrink)

According to what we call the Principle of Procreative Beneficence, couples who decide to have a child have a significant moral reason to select the child who, given his or her genetic endowment, can be expected to enjoy the most well-being. In the first part of this paper, we introduce PB, explain its content, grounds, and implications, and defend it against various objections. In the second part, we argue that PB is superior to competing principles of procreative selection such as (...) that of procreative autonomy. In the third part of the paper, we consider the relation between PB and disability. We develop a revisionary account of disability, in which disability is a species of instrumental badness that is context- and person-relative. Although PB instructs us to aim to reduce disability in future children whenever possible, it does not privilege the normal. What matters is not whether future children meet certain biological or statistical norms, but what level of well-being they can be expected to have. (shrink)

In an article in this journal, Christopher Cowley argues that we have ‘misunderstood the special nature of medicine, and have misunderstood the motivations of the conscientious objectors’. We have not. It is Cowley who has misunderstood the role of personal values in the profession of medicine. We argue that there should be better protections for patients from doctors' personal values and there should be more severe restrictions on the right to conscientious objection, particularly in relation to assisted dying. We argue (...) that eligible patients could be guaranteed access to medical services that are subject to conscientious objections by: removing a right to conscientious objection; selecting candidates into relevant medical specialities or general practice who do not have objections; demonopolizing the provision of these services away from the medical profession.

Since 1945, and particularly since the facts of the 'Heidegger case' became widely known in 1987, an enormous number of words have been devoted to establishing not only Heidegger's involvement with Nazism, but also that his philosophy is irredeemably discredited thereby. This book, while in no way denying the depth or seriousness of Heidegger's political involvement, challenges this tide of opinion, arguing that his philosophy is not compromised in any of its phases, and that acceptance of it is fully consistent (...) with a deep commitment to liberal democracy. This striking thesis is grounded in an astute examination of Heidegger's thought that will provide the reader with a clear and valuable exposition of the philosophy of one of the twentieth century's greatest thinkers.

In this paper, we investigate how data about public preferences may be used to inform policy around the use of controversial novel technologies, using public preferences about autonomous vehicles (AVs) as a case study. We first summarize the recent ‘Moral Machine’ study, which generated preference data from millions of people regarding how they think AVs should respond to emergency situations. We argue that while such preferences cannot be used to directly inform policy, they should not be disregarded. We defend an (...) approach that we call ‘Collective Reflective Equilibrium in Practice’ (CREP). In CREP, data on public attitudes function as an input into a deliberative process that looks for coherence between attitudes, behaviours and competing ethical principles. We argue that in cases of reasonable moral disagreement, data on public attitudes should play a much greater role in shaping policies than in areas of ethical consensus. We apply CREP to some of the global preferences about AVs uncovered by the Moral Machines study. We intend this discussion both as a substantive contribution to the debate about the programming of ethical AVs, and as an illustration of how CREP works. We argue that CREP provides a principled way of using some public preferences as an input for policy, while justifiably disregarding others. (shrink)

If a doctor is trying to decide whether or not to provide a medical treatment, does it matter ethically whether that treatment has already been started? Health professionals sometimes find it harder to stop a treatment (withdraw) than to refrain from starting the treatment (withhold). But does that feeling correspond to an ethical difference? In this article, we defend equivalence—the view that withholding and withdrawal of treatment are ethically equivalent when all other factors are equal. We argue that preference for (...) withholding over withdrawal could represent a form of cognitive bias—withdrawal aversion. Nevertheless, we consider whether there could be circumstances in which there is a moral difference. We identify four examples of conditional nonequivalence. Finally, we reflect on the moral significance of diverging intuitions and the implications for policy. We propose a set of practical strategies for helping to reduce bias in end-of-life decision making, including the equivalence test. (shrink)

There has been considerable recent debate on the ethics of human enhancement. A number of prominent authors have been concerned about or critical of the use of technology to alter or enhance human beings, citing threats to human nature and dignity as one basis for these concerns. Frances Kamm has given a detailed rebuttal of Sandel's arguments, arguing that human enhancement is permissible. Nicholas Agar, in his book Liberal Eugenics, argues that enhancement should be permissible but not obligatory. He argues (...) that what distinguishes liberal eugenics from the objectionable eugenic practices of the Nazis is that it is not based on a single conception of a desirable genome and that it is voluntary and not obligatory. This article takes a more provocative position. It aims to argue that, far from its being merely permissible, we have a moral obligation or moral reason to enhance ourselves and our children. Indeed, we have the same kind of obligation as we have to treat and prevent disease. It begins by considering the current interests in and possibilities of enhancement. It then offers three arguments that we have very strong reasons to seek to enhance. (shrink)

Neuroimaging studies of brain-damaged patients diagnosed as in the vegetative state suggest that the patients might be conscious. This might seem to raise no new ethical questions given that in related disputes both sides agree that evidence for consciousness gives strong reason to preserve life. We question this assumption. We clarify the widely held but obscure principle that consciousness is morally significant. It is hard to apply this principle to difficult cases given that philosophers of mind distinguish between a range (...) of notions of consciousness and that is unclear which of these is assumed by the principle. We suggest that the morally relevant notion is that of phenomenal consciousness and then use our analysis to interpret cases of brain damage. We argue that enjoyment of consciousness might actually give stronger moral reasons not to preserve a patient's life and, indeed, that these might be stronger when patients retain significant cognitive function.

Recent advances in the Super Linguistics of pictures have laid the Super Semantic foundation for modelling the phenomena of narrative sequencing and co-reference in pictorial and mixed linguistic-pictorial discourses. We take up the question of how one arrives at the pragmatic interpretations of such discourses. In particular, we offer an analysis of: (i) the discourse composition problem: how to represent the joint meaning of a multi-picture discourse, (ii) observed differences in narrative sequencing in prima facie equivalent linguistic vs pictorial discourses, (...) and (iii) the phenomenon of co-referencing across pictures. We extend Segmented Discourse Representation Theory to spell out a formal Super Pragmatics that applies to linguistic, pictorial and mixed discourses, while respecting the particular ‘genius’ of either medium and computing their distinctive pragmatic interpretations.

Reasoning that compares two objects or situations to draw conclusions about previously unknown properties of one of them has traditionally been taken to be ampliative and probabilistic. I propose that it is apodeictic reasoning from a premise about isomorphic structures that is often uncertain, but which we may have good reasons to believe. I characterize the structures and their isomorphism, describe patterns of reasoning appropriate to them, and discuss some complications not immediately obvious.

There are ethical obligations to conduct research that contributes to generalisable knowledge and improves reproductive health, and this should include embryo research in jurisdictions where it is permitted. Often, the controversial nature of embryo research can alarm ethics committee members, which can unnecessarily delay important research that can potentially improve fertility for patients and society. Such delay is ethically unjustified. Moreover, countries such as the UK, Australia and Singapore have legislation which unnecessarily captures low-risk research, such as observational research, in (...) an often cumbersome and protracted review process. Such countries should revise such legislation to better facilitate low-risk embryo research.We introduce a philosophical distinction to help decision-makers more efficiently identify higher risk embryo research from that which presents no more risks to persons than other types of tissue research. That distinction is between future person embryo research and non-future person embryo research. We apply this distinction to four examples of embryo research that might be presented to ethics committees.Embryo research is most controversial and deserving of detailed scrutiny when it potentially affects a future person. Where it does not, it should generally require less ethical scrutiny. We explore a variety of ways in which research can affect a future person, including by deriving information about that person, and manipulating eggs or sperm before an embryo is created. (shrink)

This book argues that correspondence theories of truth fail because the relation that holds between a true thought and a fact is that of identity, not correspondence. Facts are not complexes of worldly entities which make thoughts true they are merely true thoughts. According to Julian Dodd, the resulting modest identity theory, while not defining truth, correctly diagnoses the failure of correspondence theories, and thereby prepares the ground for a defensible deflation of the concept of truth.

ABSTRACT It is accepted that treatment of previously competent, now incompetent patients can be limited if that is what the patient would desire, if she were now competent. Expressed past preferences or an advance directive are often taken to constitute sufficient evidence of what a patient would now desire. I distinguish between desires and rational desires. I argue that for a desire to be an expression of a person's autonomy, it must be or satisfy that person's rational desires. A person (...) rationally desires a course of action if that person desires it while being in possession of all available relevant facts, without committing relevant error of logic, and “vividly imagining” what its consequences would be like for her. I argue that some competent, expressed desires obstruct autonomy. I show that several psychological mechanisms operate to prevent a person rationally evaluating what future life in a disabled state would be like. Rational evaluation is difficult. However, treatment limitation, if it is to respect autonomy, must be in accord with a patient's rational desires, and not merely her expressed desires. I illustrate the implications of these arguments for the use of advance directives and for the treatment of competent patients. (shrink)

In this paper, we offer a new account of disability. According to our account, some state of a person's biology or psychology is a disability if that state makes it more likely that a person's life will get worse, in terms of his or her own wellbeing, in a given set of social and environmental circumstances. Unlike the medical model of disability, our welfarist approach does not tie disability to deviation from normal species’ functioning, nor does it understand disability in (...) essentialist terms. Like the social model of disability, the welfarist approach sees disability as a harmful state that results from the interaction between a person's biology and psychology and his or her surrounding environment. However, unlike the social model, it denies that the harm associated with disability is entirely due to social prejudice or injustice. In this paper, we outline and clarify the welfarist approach, answer common objections and illustrate its usefulness in addressing a range of difficult ethical questions involving disability.

In 2011 the English Court of Protection ruled that it would be unlawful to withdraw artificial nutrition and hydration from a woman, M, who had been in a minimally conscious state for 8 years. It was reported as the first English legal case concerning withdrawal of artificial nutrition and hydration from a patient in a minimally conscious state who was otherwise stable. In the absence of a valid and applicable advance decision refusing treatment, of other life-limiting pathology or excessively burdensome (...) suffering, the judgement makes it clear that the obligation on health professionals falls strongly in favour of preserving life. Although the Court sought to limit the judgement as closely as possible to the facts of the case, it is likely to have a significant impact on life-sustaining treatment decisions for people in states of low awareness. This paper outlines the main legal features of the judgement. (shrink)

In this review article we describe the current scope, methods, and contents of medical ethics education in medical schools in Western English speaking countries (mainly the United Kingdom, the United States, and Australia). We assess the strengths and weaknesses of current medical ethics curricula, and students’ levels of satisfaction with different teaching approaches and their reported difficulties in learning medical ethics concepts and applying them in clinical practice. We identify three main challenges for medical ethics education: counteracting the bad effects (...) of the “hidden curriculum,” teaching students how to apply ethical knowledge and critical thinking to real cases in clinical practice, and shaping future doctors’ right character through ethics education. We suggest ways in which these challenges could be addressed. On the basis of this analysis, we propose practical guidelines for designing, implementing, teaching, and assessing a medical ethics program within a four-year medical course. (shrink)

The psychedelic psilocybin has shown promise both as treatment for psychiatric conditions and as a means of improving well-being in healthy individuals. In some jurisdictions (e.g., Oregon, USA), psilocybin use for both purposes is or will soon be allowed and yet, public attitudes toward this shift are understudied. We asked a nationally representative sample of 795 US Americans to evaluate the moral status of psilocybin use in an appropriately licensed setting for either treatment of a psychiatric condition or well-being enhancement. (...) Showing strong bipartisan support, participants rated the individual’s decision as morally positive in both contexts. These results can inform effective policy-making decisions around supervised psilocybin use, given robust public attitudes as elicited in the context of an innovative regulatory model. We did not explore attitudes to psilocybin use in unsupervised or non-licensed community or social settings. (shrink)

According to Bertrand Russell, Nietzsche's only value is the flourishing of the exceptional individual. The well-being of ordinary people is, in itself, without value. Yet there are passages in Nietzsche that appear to regard the flourishing of the community as a whole alongside, perhaps even above, that of the exceptional individual. The ten essays that comprise this volume wrestle with the tension between individual and community in Nietzsche's writings. Some defend a reading close to Russell's. Others suggest that Nietzsche's highest (...) value is the flourishing of the community as a whole and that exceptional individuals find their highest value only in promoting that flourishing. In viewing Nietzsche from the perspective of community, the essays also cast new light on other aspects of his philosophy, for instance, his ideal of scientific research and his philosophy of language.

Anti-realism is plagued by Fitch’s paradox: the remarkable result that if one accepts that all truths are knowable, minimal assumptions about the nature of knowledge entail that every truth is known. Dorothy Edgington suggests to address this problem by understanding p is knowable to be a counterfactual claim, but her proposal must contend with a forceful objection by Timothy Williamson. I revisit Edgington’s basic idea and find that Williamson’s objection is obviated by a refined understanding of counterfactual knowability that is (...) grounded in possible courses of inquiry. I arrive at a precise definition of knowability that is not just a technical avoidance of paradox, but is metaphysically sound and does justice to the anti-realist idea. (shrink)

Stephen Read presented harmonious inference rules for identity in classical predicate logic. I demonstrate here how this approach can be generalised to a setting where predicate logic has been extended with epistemic modals. In such a setting, identity has two uses. A rigid one, where the identity of two referents is preserved under epistemic possibility, and a non-rigid one where two identical referents may differ under epistemic modality. I give rules for both uses. Formally, I extend Quantified Epistemic Multilateral Logic (...) with two identity signs. I argue that a uniform meaning for identity tout court can be given by adopting Maria Aloni’s account of reference using conceptual covers. We obtain a harmonious set of rules for identity that is sound and complete for Aloni’s model theory. (shrink)

In her excellent and comprehensive article, Friesen argues that utilising personal responsibility in healthcare is problematic in several ways: it is difficult to ascribe responsibility to behaviour; there is a risk of prejudice and bias in deciding which behaviours a person should be held responsible for; it may be ineffective at reducing health costs. In this short commentary, I will elaborate the critique of personal responsibility in health but suggest one way in which it could be used ethically. In doing (...) so, I will introduce the concepts of reasonable risk and golden opportunity. I previously argued that it is both difficult to disentangle responsibility and that we risk prejudice and bias in singling out behaviours that are socially disapproved of.1 So I am sympathetic to Friesen’s concerns. I also discussed another way in which ascribing personal responsibility for health is problematic which Friesen does not discuss and which, in my view, is the most concerning and further supports her arguments. It represents a back door assault on liberalism and neutrality towards concepts of the good life. Even if one were to accurately and in an unbiased way divine the personal contribution to disease, the greatest problem would remain: those who voluntarily take on risk would be penalised. That is, such a system would be risk-averse. Those lives which avoided risk would be prioritised, while those who chose to take on risky activities in their conception of the good life would be penalised. Yet risk is necessary, both for the good life, and social progress. Columbus, Edmund Hilary, Florence Nightingale, Ernest Hemingway and countless monumental figures in human history took risks in order to achieve something great. Should we aim for a society of trembling, teetotalling health nuts? Surely that prospect is horrific. It is horrific because it elevates health …. (shrink)

We examine the philosophical and ethical issues associated with conjoined twins and their surgical separation. In cases in which there is an extensive sharing of organs, but nevertheless two distinguishable functioning brains, there are a number of philosophical and ethical challenges. This is because such conjoined twins: 1. give rise to puzzles concerning our identity, about whether we are identical to something psychological or biological;2. force us to decide whether what matters from an ethical point of view is the biological (...) life of our organisms or the existence of our consciousness or mind; 3. raise questions concerning when, if ever, it is morally acceptable to sacrifice one of us to save another;4. force us to reflect on the conditions for ownership of organs and the justification of removal of organs for transplantation which causes the death of the donor; 5. raise questions about who should take decisions about life-risking treatments when this cannot be decided by patients themselves.We examine and suggest answers to these questions.

We review recent research to introduce human brain organoids into the brains of infant rats. This research shows these organoids integrate and function to affect behaviour in rats.

We situate this research in the broader context of the biological revolution, arguing we already have the technological power to create fully human embodied animals. This raises profound, (...) so far unaddressed ethical issues which call for urgent attention. (shrink)

In January 2012, the Journal of Medical Ethics published online Giubilini and Minerva's paper, ‘After-birth abortion. Why should the baby live?’.1 The Journal publishes articles based on the quality of their argument, their contribution to the existing literature, and relevance to current medicine. This article met those criteria. It created unprecedented global outrage for a paper published in an academic medical ethics journal. In this special issue of the Journal, Giubilini and Minerva's paper comes to print along with 31 articles (...) from some of the best scholars in the world, from the broadest range of perspectives on abortion and infanticide, including those strongly critical of Giubilini and Minerva.The killing of a baby is among the most shocking of human practices. I am strongly opposed to the legalisation of infanticide along the lines discussed by Giubilini and Minerva. But I would like to explain why a journal of medical ethics published an article examining infanticide and now devotes a special issue to bringing a wide range of perspectives for further examination of these issues.Infanticide has been practised throughout human history for various reasons and continues to be practised today throughout the world. In rare cases, infanticide can be practised openly and legally—for example, as specified under the ‘Groningen Protocol’, in the Netherlands. The Groningen Protocol allows doctors to end the life of neonates at the request of their parents if the infant is experiencing hopeless and unbearable suffering.2But medical infanticide arguably occurs elsewhere other than in the Netherlands today.In neonatal intensive care, it is not uncommon for a doctor to withdraw artificial ventilation with the consequence that a baby dies.3 If anyone else performed that act, including the parents of the child, it would be viewed as an act of homicide, in some cases ….

Much disease and disability is the result of lifestyle behaviours. For example, the contribution of imprudence in the form of smoking, poor diet, sedentary lifestyle, and drug and alcohol abuse to ill-health is now well established. More importantly, some of the greatest challenges facing humanity as a whole – climate change, terrorism, global poverty, depletion of resources, abuse of children, overpopulation – are the result of human behaviour. In this chapter, we will explore the possibility of using advances in the (...) cognitive sciences to develop strategies to intentionally manipulate human motivation and behaviour. While our arguments apply also to improving prudential motivation and behaviour in relation to health, we will focus on the more controversial instance: the deliberate targeted use of biomedicine to improve moral motivation and behaviour. We do this because the challenge of improving human morality is arguably the most important issue facing humankind (Persson and Savulescu, forthcoming). We will ask whether using the knowledge from the biological and cognitive sciences to influence motivation and behaviour erodes autonomy and, if so, whether this makes it wrong. (shrink)

The knowledge norm of assertion is the subject of a lively debate on when someone is in a position to assert something. However, not much has been said about the logic that underlies such debate.

Afterwards, I investigate some problems that this formalisation makes visible. This reveals some significant limitations of the underlying logic: it can neither contain (...) Axiom 4 nor Axiom C4. Moreover, sentences of the form p and I have not asserted that p appear to licence a violation of deontic rules. (shrink)
