Policymakers and institutions have developed an increasing interest in applying principles from cognitive science to encourage individuals to adopt behaviors, attitudes and perspectives that enable them to reach higher levels of personal and collective well-being. We focused on the value of nudging people to adopt a broader farsighted view when making their day-to-day decisions, overcoming the temporal discounting bias which leads them to prefer smaller immediate gains to larger future rewards. Following recent advances in the literature, we tried to mitigate (...) this myopia promoting the connection that individuals feel between their present and future selves through a nudge which capitalizes on their natural tendency to illusory superiority. We defined and tested a paradigm to exploit persuasively this optimistic bias to mitigate temporal discounting through the mediation of an increased future self-continuity. Implications for well-being and public policies are discussed. (shrink)

This is an opinionated guide to the literature on epistemic dilemmas. It discusses seven kinds of situations where epistemic dilemmas appear to arise; dilemmic, dilemmish, and non-dilemmic takes on them; and objections to dilemmic views along with dilemmist’s replies to them.

Dementia affects millions of people throughout the world. Thinking through Dementia offers a critique of the main models used to understand dementia-the biomedical, neuropsychological, and social constructionist. It discusses clinical issues and cases, together with philosophical work that might help us to better understand and treat this illness.

Epistemologists spend a great deal of time thinking about how we should respond to our evidence. They spend far less time thinking about the ways that evidence can be acquired in the first place. This is an oversight. Some ways of acquiring evidence are better than others. Many normative epistemologies struggle to accommodate this fact. In this article I develop one that can and does. I identify a phenomenon – epistemic feedback loops – in which evidence acquisition has gone awry, (...) with the result that even beliefs based on the evidence are irrational. Examples include evidence acquired under the influence of confirmation bias and evidence acquired under the influence of cognitively penetrated experiences caused by implicit bias. I then develop a theoretical framework which enables us to understand why beliefs that are the outputs of epistemic feedback loops are irrational. Finally, I argue that many popular approaches to epistemic normativity may need to be abandoned on the grounds that they cannot comfortably explain feedback loops. The scope of this last claim is broad: it includes almost all contemporary theories of justified/rational belief and of the epistemology of cognitive penetration. (shrink)

R.I.G Hughes offers the first detailed and accessible analysis of the Hilbert-space models used in quantum theory and explains why they are so successful.

Epistemologists often appeal to the idea that a normative theory must provide useful, usable, guidance to argue for one normative epistemology over another. I argue that this is a mistake. Guidance considerations have no role to play in theory choice in epistemology. I show how this has implications for debates about the possibility and scope of epistemic dilemmas, the legitimacy of idealisation in Bayesian epistemology, uniqueness versus permissivism, sharp versus mushy credences, and internalism versus externalism.

Transhumanism, the belief that technology can transcend the limitations of the human body and brain, is part of the family of Enlightenment philosophies. As such, transhumanism has also inherited the internal tensions and contradictions of the broad Enlightenment tradition. First, the project of Reason is self-erosive and requires irrational validation. Second, although most transhumanists are atheist, their belief in the transcendent power of intelligence generates new theologies. Third, although most transhumanists are liberal democrats, their belief in human perfectibility and governance (...) by reason can validate technocratic authoritarianism. Fourth, transhumanists are divided on the balance between democracy and the market. Fifth, teleological expectations of unstoppable progress are in tension with awareness of the indeterminacy of the future. Sixth, transhumanists are divided between advocates of ethical universalism and ethical relativism. Seventh, the rational materialist denial of discrete persistent selves calls into question the transhumanist project of individual longevity and enhancement. (shrink)

This article draws on a five-year, multi-sited transnational research project on the global traffic in human organs, tissues, and body parts from the living as well as from the dead as a misrecognized form of human sacrifice. Capitalist expansion and the spread of advanced medical and surgical techniques and developments in biotechnology have incited new tastes and traffic in the skin, bones, blood, organs, tissues, marrow and reproductive and genetic marginalized other. Examples drawn from recent ethnographic research in Israel, the (...) Palestinian Authority and Turkey serve to cast light on the dark side of organs harvesting and transplantation. The article focuses on the dangers of the `fetishized kidney' for both sellers and buyers, for whom this new commodity has become an organ of opportunity and an organ of last resort. The bodily sacrifice is disguised as a donation, rendered invisible by its anonymity, and hidden under the medical rhetoric of `life saving' and `gift giving'. It suggests that the ultimate fetish as recognized long ago by Ivan Illich is the idea of `life' as object of manipulation. (shrink)

Many assume that whenever government is entitled to make a law, it is entitled to enforce that law coercively. I argue that the justification of legal authority and the justification of governmental coercion come apart. Both in ideal theory and in actual human societies, governments are sometimes entitled to make laws that they are not entitled to enforce coercively.

Disturbances to one's sense of self, the feeling that one has ‘lost a part of oneself’ or that one ‘no longer feels like oneself,’ are frequently recounted throughout the bereavement literature. Engaging Allan Køster's important contribution to this issue, this article reinforces his suggestion that, by rupturing the existential texture of self-familiarity, bereavement can result in experiences of estrangement that can be meaningfully understood according to the concept of self-alienation. Nevertheless, I suggest that whilst Køster's relational interpretation of alienation as (...) the withdrawal of heteronomy can be applied to the experience of world-collapse in bereavement, what sets bereavement apart from other limit situations is the fact that it involves an intersubjective relation between the living and the dead. In contrast to Køster, therefore, I suggest that the experience of self-alienation that is distinctive to bereavement results from the fact that the bereaved is exposed to, and co-opted by, the absolute alterity of death itself.

Williamson (2000) appeals to considerations about when it is natural to say that a hypothesis is consistent with one’s evidence in order to motivate the claim that all and only knowledge is evidence. It is argued here that the relevant considerations do not support this claim, and in fact conflict with it.

When a loved one dies, it is common for the bereaved to feel profoundly lonely, disconnected from the world with the sense that they no longer belong. In philosophy, this experience of ‘loss and loneliness’ has been interpreted according to both a loss of possibilities and a loss of the past. But it is unclear how these interpretations apply to the distinctive way in which loss and loneliness manifest in old age. Drawing on the phenomenological analyses of old age given (...) by de Beauvoir and Améry, I consider how the diminishment of the capacity for projection and recollection complicate recent interpretations of loss and loneliness, whilst nevertheless reinforcing the conclusion that in old age subjectivity is necessarily impoverished. Developing a critical stance on de Beauvoir and Améry’s underlying conception of subjectivity, I turn to Levinas in considering whether or not there is a way to reimagine subjectivity such that the estrangement and alienation of older adults might be ameliorated rather than exacerbated. Grounded in the passive body-in-itself rather than the self-transcending capacity of the body-for-itself, I suggest it becomes possible to reconceptualise the experience of loss and loneliness in old age; both in terms of what is lost and what needs to be restored if older adults are to be helped to find themselves at home in the world in the midst of, and indeed because of, manifold loss.

This paper sets out to defend human genetic engineering with a new bioethical approach, post-humanism, combined with a radical democratic political framework. Arguments for the restriction of human genetic engineering, and specifically germ-line enhancement, are reviewed. Arguments are divided into those which are fundamental matters of faith, or "bio-Luddite" arguments, and those which can be addressed through public policy, or "gene-angst" arguments.The four bio-Luddite concerns addressed are: Medicine Makes People Sick; There are Sacred Limits of the Natural Order; Technologies Always (...) Serve Ruling Interests; The Genome is Too Complicated to Engineer. I argue that these are matters of faith that one either accepts or rejects, and that I reject.The non-fundamentalist or pragmatic concerns I discuss are: Fascist Applications; The Value of Genetic Diversity; The Geneticization of Life; Genetic Discrimination and Confidentiality; Systematically Bad Decisions by Parents; Discrimination Against the Disabled; Unequal Access; The Decline of Social Solidarity. I conclude that all these concerns can be adequately addressed through a proactive regulative framework administered by a liberal democratic state. Therefore, even germ-line genetic enhancement should eventually made available since the potential benefits greatly outweigh the potential risks. (shrink)

This article argues that there can be epistemic dilemmas: situations in which one faces conflicting epistemic requirements with the result that whatever one does, one is doomed to do wrong from the epistemic point of view. Accepting this view, I argue, may enable us to solve several epistemological puzzles.

I develop a broadly reliabilist theory of non-ideal epistemic rationality and argue that if it is correct we should reject the recently popular idea that the standards of non-ideal epistemic rationality are mere social conventions.

Enlightenment values are built around the presumption of an independent rational self, citizen, consumer and pursuer of self-interest. Even the authoritarian and communitarian variants of the Enlightenment presumed the existence of autonomous individuals, simply arguing for greater weight to be given to their collective interests. Since Hume, however, radical Enlightenment empiricists have called into question the existence of a discrete, persistent self. Today neuroscientific reductionism has contributed to the rejection of an essentialist model of personal identity. Contemporary transhumanism has yet (...) to grapple with the radical consequences of the erosion of liberal individualism on their projects of individually chosen enhancement and longevity. Most transhumanists still reflect an essentialist idea of personal identity, even as they embrace projects of radical cognitive enhancement that would change every constituent element of consciousness. Transhumanists need to grapple with how their projects and ethics would change if personal identity is an arbitrary, malleable fiction. (shrink)

Philosophers often claim that humility is a dependent virtue: a virtue that depends on another virtue for its value. I consider three views about this relation: Specific Dependence, Unspecific Dependence, and Fittingness. I argue that, since humility cannot uniquely depend on another virtue, and since this uniqueness is desirable, we should reject Specific and Unspecific Dependence. I defend a Fittingness view, according to which the humble person possesses some objectively good quality fitting for humility. I show beyond Slote’s original characterization (...) of the dependence relation that, even if humility’s value depends on having objectively good qualities, humility itself can be one such quality. So, humility can depend on itself. I call this view Bootstrapped Fittingness. (shrink)

Does the content of a physically dangerous job affect the moral permissibility of hiring for that job? To what extent may employers consider costs in choosing workplace safety measures? Drawing on Kantian ethical theory, this article defends two strong ethical standards of workplace safety. First, the content of a hazardous job does indeed affect the moral permissibility of offering it. Unless employees need hazard pay to meet basic needs, it is permissible to offer a dangerous job only if prospective employees (...) have a reason other than hazard pay to choose this job instead of safer alternatives. Second, employers typically cannot justify omitting expensive safety measures by paying employees more, even if employees prefer higher pay to greater safety. Employers offering dangerous jobs must meet these two standards to avoid treating their employees merely as means. (shrink)

Contemporary debates on obedience and consent, such as those between Thomas Senor and A. John Simmons, suggest that either political obligation must exist as a concept or there must be natural duty of justice accessible to us through reason. Without one or the other, de facto political institutions would lack the requisite moral framework to engage in legitimate coercion. This essay suggests that both are unnecessary in order to provide a conceptual framework in which obedience to coercive political institutions can (...) be understood. By providing a novel reading of Hobbes’s Leviathan, this article argues that both political obligation and a natural duty to justice are unnecessary to ground the ability of political institutions to engage in legitimate coercion. This essay takes issue with common readings of Hobbes which assume consent is necessary to generate obedience on the part of citizens, and furthermore that political obligation is critical for the success of political institutions. While the failure of the traditional Hobbesian narrative of a consenting individual would seem to suggest the Leviathan is indefensible as a project, this paper argues that the right of war in the state of nature was more central for Hob- bes’s understanding of political institutions than obligation. Furthermore, Hobbes provides an adequate defense of political institutions even if his arguments about consent, obligation and punishment are only rhetorical. In this way Hobbesian law is best understood as a set of practical requirements to avoid war, and not as moral requirements that individuals are bound to comply with. Thus Hobbesian political institutions are not vulnerable to contemporary philosophical anarchist criticisms about political obligation and political institutions as such. To develop this reading, I focus primarily on the Leviathan, including interpretations by Skinner, Kateb, Flathman, and Oakeshott. Ultimately, this argument provides insight into contem- porary political institutions of the state, citizenship, criminality, and the law in a world where political obligation has not been adequately justified.

Boredom is an affective experience that can involve pervasive feelings of meaninglessness, emptiness, restlessness, frustration, weariness and indifference, as well as the slowing down of time. An increasing focus of research in many disciplines, interest in boredom has been intensified by the recent Covid-19 pandemic, where social distancing measures have induced both a widespread loss of meaning and a significant disturbance of temporal experience. This article explores the philosophical significance of this aversive experience of ‘pandemic boredom.’ Using Heidegger’s work as (...) a unique vantage point, this article draws on survey data collected by researchers in an ongoing project titled ‘Experiences of Social Distancing During the Covid-19 Pandemic’ to give an original phenomenological interpretation of the meaninglessness and monotony of pandemic boredom. On a Heideggerian interpretation, pandemic boredom involves either a situative confrontation with relative meaninglessness that upholds our absorption in the everyday world, or an existential confrontation with absolute meaninglessness that forces us to take up the question of our existence. Arguing that boredom during the pandemic makes this distinction difficult to sustain, I consider some of the ways in which pandemic boredom might be seen to expose and then exceed the distinctive methodological limitations of Heidegger’s philosophical interpretation of boredom.

The author explores the connection between morality and principles of critical thinking as a way to encourage students to take ethic and moral concepts seriously in introductory courses. The skeptical attitude of students in introductory courses often hampers students critically engaging with questions of morality. Moral values and judgments are only valid for students if contextualized in historical epochs or cultures, and often are conceived as opinions. The author examines Bishop Butler's moral theory and argues for its incorporation into the (...) introductory philosophy curriculum. Butler’s moral theory introduces students to philosophical method and moral reasoning, which the author argues counteracts students’ initial skeptical responses to ethical and moral theory. Butler’s theory demonstrates the importance of the clarification of terms, connections between thought and truth, and the overall importance of philosophical argumentation in moral theory. (shrink)

Recently, dramatic price increases by several pharmaceutical companies have provoked public outrage. These scandals raise questions both about how pharmaceutical firms should be regulated and about how pharmaceutical executives ethically ought to make pricing decisions when drug prices are largely unregulated. Though there is an extensive literature on the regulatory question, the ethical question has been largely unexplored. This article defends a Kantian approach to the ethics of pharmaceutical pricing in an unregulated market. To the extent possible, pharmaceutical companies must (...) price drugs so that those who genuinely need them can get them without financial ruin. This requirement is an ethical side constraint, like the moral prohibitions on deception and theft, that takes precedence over a business’s interest in maximizing profit. That said, the requirement’s application is sensitive to the need to recoup the costs of research and to produce a return that financially justifies the original investment. It may not be either feasible or desirable for government to attempt to enforce the ethical requirements concerning just pharmaceutical pricing. Either price regulation or subsidy could fulfill government’s obligation to protect patients from being objectionably vulnerable to pricing decisions by private companies. (shrink)

R.I.G. Hughes presents a series of eight philosophical essays on the theoretical practices of physics. The first two essays examine these practices as they appear in physicists' treatises (e.g. Newton's Principia and Opticks ) and journal articles (by Einstein, Bohm and Pines, Aharonov and Bohm). By treating these publications as texts, Hughes casts the philosopher of science in the role of critic. This premise guides the following 6 essays which deal with various concerns of philosophy of physics such (...) as laws, disunities, models and representation, computer simulation, explanation, and the discourse of physics.

Moshe Tati, a sanitation worker in Jerusalem, was among the first of more than a thousand mortally sick Israelis who signed up for illicit and clandestine ‘transplant tour’ packages that included: travel to an undisclosed foreign and exotic setting; five-star hotel accommodation; surgery in a private hospital unit; a ‘fresh’ kidney purchased from a perfect stranger trafficked from a third country. Although Tati’s holiday turned into a nightmare and he had to be emergency air-lifted from a rented transplant unit in (...) a private hospital in Adana, Turkey back to Israel, Moshe became a poster-boy of transplant tourism for the next decade. João Cavalcanti was among the first of 38 residents of the slums of Recife recruited by retired military Captain Ivan da Silva and his sidekick Captain Gadddy Tauber to travel to Durban, South Africa to provide a spare kidney to an Israeli transplant tourist in Durban. This article examines the logics and practices through which kidney buyers and kidney sellers, organs brokers, surgeons and their accessories convince themselves that they are engaged in an illegal but still mutually beneficial ‘medical-recreational’ adventure, an ‘extreme medical sport’ of sorts. While life, health and survival motivate ‘transplant tourism’, a euphemism for human trafficking in spare body parts, the freedom to roam, mobility, is an essential feature of transplant tours for kidney buyers and kidney sellers.

People have sought ways to improve their physical and mental capabilities for thousands of years. For those of us who believe that human enhancement technologies include clothes, tools and weapons, the politics of enhancement started in prehistory. The norms of pre-industrial societies that only certain castes or genders could touch specific tools or wear certain clothes were preliminary politics of enhancement. Prosthetic limbs are thousands of years old, and by the 15th century, there were multiple experiments with vaccination around the (...) world. Although it would be appropriate to write a history of the various forms of empowerment that have taken place since the dawn of civilisation, this volume – that now we can present to the lectors – will be on the debates about human enhancement that began in the early 20th century, once modern medicine had begun to suggest actual technologies for human augmentation. Before examining the relationship between human enhancement and biopolitics (the subject of our work), it is helpful to say a few words about the series in which this volume appears, a series that bears the same title as this first text and which opens with contributions from the best scientific experts on the subject.

Originally published in 1965. This is a textbook of modern deductive logic, designed for beginners but leading further into the heart of the subject than most other books of the kind. The fields covered are the Propositional Calculus, the more elementary parts of the Predicate Calculus, and Syllogistic Logic treated from a modern point of view. In each of the systems discussed the main emphases are on Decision Procedures and Axiomatisation, and the material is presented with as much formal rigour (...) as is compatible with clarity of exposition. The techniques used are not only described but given a theoretical justification. Proofs of Consistency, Completeness and Independence are set out in detail. The fundamental characteristics of the various systems studies, and their relations to each other are established by meta-logical proofs, which are used freely in all sections of the book. Exercises are appended to most of the chapters, and answers are provided. (shrink)

The neurodiversity paradigm is presented by its proponents as providing a philosophical foundation for the activism of the neurodiversity movement. Its central claims are that autism and other neurodivergent conditions are not disorders because they are not intrinsically harmful, and that they are valuable, natural and/or normal parts of human neurocognitive variation. This paper: (a) identifies the non‐disorder claim as the most central of these, based on its prominence in the literature and connections with the practical policy claims that the (...) paradigm is supposed to support; (b) describes the heterogeneity of autism at the behavioural and causal levels, and argues that at the behavioural level this encompasses ways of being autistic that are harmful in ways that cannot be not wholly attributed to discrimination or unjust social arrangements, challenging the claim that autism is not a disorder; (c) considers and rejects responses to this challenge based on separation of high‐ and low‐functioning autism, separation of autism from co‐occurring conditions, and viewing autism as part of an individual’s identity. Two of these responses fail for reasons that are themselves connected with the behavioural and/or causal heterogeneity of autism. (shrink)

In a recent article in this journal, Savulescu and Schuklenk defend and extend their earlier arguments against a right to medical conscientious objection in response to criticisms raised by Cowley. I argue that while it would be preferable to be less accommodating of medical conscientious than many countries currently are, Savulescu and Schuklenk's argument that conscientious objection is ‘simply unprofessional’ is mistaken. The professional duties of doctors should be defined in relation to the interests of patients and society, and for (...) reasons set out in this article, these may support limited accommodation of conscientious objection on condition that it does not impede access to services. Moreover, the fact that conscientious objection appears to involve unjustifiable compromise from the objector's point of view is not a reason for society not to offer that compromise. Arguing for robust enforcement of the no-impediment condition, rather than opposing conscientious objection in principle, may be a more effective way of addressing the harms resulting from an over-permissive conscientious objection policy.

In their recent article, ‘Why lockdown of the elderly is not ageist and why levelling down equality is wrong’, Savulescu and Cameron argue for selective isolation of the elderly as an alternative to general lockdown. An important part of their argument is the claim that the latter amounts to ‘levelling down equality’ and that this is ‘unethical’ or even ‘morally repugnant’. This response argues that they fail to justify either part of this claim: the claim that levelling down is always (...) morally wrong is subject to challenges that Savulescu and Cameron do not consider; and a policy of maintaining general lockdown does not constitute levelling down, as it provides absolute benefits to those who would be worse off under selective isolation.

Government’s use of imprisonment raises distinctive moral issues. Even if government has broad authority to make and to enforce law, government may not be entitled to use imprisonment as a punishment for all the criminal laws it is entitled to make. Indeed, there may be some serious crimes that it is wrong to punish with imprisonment, even if the conditions of imprisonment are humane and even if no adequate alternative punishments are available.
