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.

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.

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)

Daniel Greco (forthcoming) argues that there cannot be epistemic dilemmas. I argue that he is wrong. I then look in detail at a would-be epistemic dilemma and argue that no non-dilemmic approach to it can be made to work. Along the way, there is discussion of octopuses, lobsters, and other ‘inscrutable cognizers’; the relationship between evaluative and prescriptive norms; a failed attempt to steal a Brueghel; epistemic and moral blame and residue; an unbearable guy who thinks he’s God’s gift to (...) women; excuses; stupid games involving hats; radical permissivism; how I’ll never be able to afford to buy a house in Hampstead; and many other exciting topics.

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.

I consider a number of reasons one might think we should only accept epistemic dilemmas in our normative epistemology as a last resort and argue that none of them is compelling.

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.

Hyman (1999, 2006) argues that knowledge is best conceived as a kind of ability: S knows that p iff S can φ for the reason that p. Hyman motivates this thesis by appealing to Gettier cases. I argue that it is counterexampled by a certain kind of Gettier case where the fact that p is a cause of the subject’s belief that p. One can φ for the reason that p even if one does not know that p. So knowledge (...) is not best conceived as an ability of this kind. (shrink)

Recently it has been increasingly popular to argue that knowledge is the norm of belief. I present an argument against this view. The argument trades on the epistemic situation of the subject in the bad case. Notably, unlike with other superficially similar arguments against knowledge norms, knowledge normers preferred strategy of appealing to the distinction between permissibility and excusability cannot help them to rebut this argument.

I argue that evidentialism should be rejected because it cannot be reconciled with empirical work on bias in cognitive and social psychology.

I argue that it is epistemically permissible to believe that P when it is epistemically rational to believe that P. Unlike previous defenses of this claim, this argument is not vulnerable to the claim that permissibility is being confused with excusability.

It is widely thought that moral obligations are necessarily guidance giving. This supposed fact has been put to service in defence of the ‘ought-implies-can’ principle according to which one cannot be morally obligated to do the impossible, since impossible-to-satisfy obligations would not give guidance. It is argued here that the supposed fact is no such thing; moral obligations are not necessarily guiding giving, and so the ‘guidance argument’ for ought-implies-can fails. This is the result of no non-trivial condition being ‘luminous’.

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.

It is often argued that the requirement that moral obligations be ‘action guiding’ motivates the claim that one can be obligated to ϕ only if one can ϕ. I argue that even on its most plausible interpretation, this argument fails, since the reasoning behind it leads to the absurd conclusion that one is permitted to ϕ if one cannot ϕ.

ABSTRACTI describe two ways of thinking about what constitutes a knowledgeable assertion – the ‘orthodox view’ and the ‘isomorphic view’. I argue that we should discard the orthodox view and replace it with the isomorphic view. The latter is more natural and has greater theoretical utility than the former.

Population-level biomedical research offers new opportunities to improve population health, but also raises new challenges to traditional systems of research governance and ethical oversight. Partly in response to these challenges, various models of public involvement in research are being introduced. Yet, the ways in which public involvement should meet governance challenges are not well understood. We conducted a qualitative study with 36 experts and stakeholders using the World Café method to identify key governance challenges and explore how public involvement can (...) meet these challenges. This brief report discusses four cross-cutting themes from the study: the need to move beyond individual consent; issues in benefit and data sharing; the challenge of delineating and understanding publics; and the goal of clarifying justifications for public involvement. The report aims to provide a starting point for making sense of the relationship between public involvement and the governance of population-level biomedical research, showing connections, potential solutions and issues arising at their intersection. We suggest that, in population-level biomedical research, there is a pressing need for a shift away from conventional governance frameworks focused on the individual and towards a focus on collectives, as well as to foreground ethical issues around social justice and develop ways to address cultural diversity, value pluralism and competing stakeholder interests. There are many unresolved questions around how this shift could be realised, but these unresolved questions should form the basis for developing justificatory accounts and frameworks for suitable collective models of public involvement in population-level biomedical research governance.

This paper examines an ideology I call techno-colonialism. I argue that techno-colonialism represents an attempt to selectively reproduce settler colonial practices adjusted to twenty-first century realities. This argument has implications for contemporary settler colonialism, the radical right, and climate change politics. In what follows, I discuss the techno-colonial doctrines of Nick Land, Curtis Yarvin, Peter Thiel, and Patri Friedman. These figures articulate a political theory about exploiting new technologies to escape the state and found new societies. To explore techno-colonial (...) ideology, I focus on Seasteading—the practice of creating floating city-states to colonize the ocean––as an attempted realization of techno-colonial ideals. As I claim, techno-colonialism attempts to humanize the politics of settlement. But I argue that techno-colonialism's ambitions fail, and techno-colonialism fails to create a harmless politics of settlement. I conclude that we should be attentive to the relations of political and economic power in which such exit projects are embedded. Moreover, this paper also promotes our understanding of climate change and the radical right's politics. While scholars most naturally associate the radical right with climate change denialism, the techno-colonists illustrate another possibility. They welcome catastrophe, and see rising-sea levels as an opportunity to start society afresh. (shrink)

Jennifer Hornsby has defended the Reasons-Knowledge Thesis : the claim that \-ing because p requires knowing that p, where the ‘because’ at issue is a rationalising ‘because’. She defends by appeal to the thought that it provides the best explanation of why the subject in a certain sort of Gettier case fails to be in a position to \ because p. Dustin Locke and, separately, Nick Hughes, present some modified barn-façade cases which seem to constitute counterexamples to and (...) undermine Hornsby’s way of motivating it by rendering their alternative Reasons-Explanation Thesis a better explanation of Hornsby’s datum. This paper defends and Hornsby’s argument for it against those objections. First, I point out that their supposedly intuitive verdict about the relevant barn-façade cases is not as intuitive as they think. Second, I point out that even if we share the intuition: we have strong reason to doubt the verdict anyway. And finally, I point out that since is independently implausible, the two problems can be tackled anyway. (shrink)

Proposals to make us smarter than the greatest geniuses or to add thousands of years to our life spans seem fit only for the spam folder or trash can. And yet this is what contemporary advocates of radical enhancement offer in all seriousness. They present a variety of technologies and therapies that will expand our capacities far beyond what is currently possible for human beings. In _Humanity's End,_ Nicholas Agar argues against radical enhancement, describing its destructive consequences. Agar examines the (...) proposals of four prominent radical enhancers: Ray Kurzweil, who argues that technology will enable our escape from human biology; Aubrey de Grey, who calls for anti-aging therapies that will achieve "longevity escape velocity"; Nick Bostrom, who defends the morality and rationality of enhancement; and James Hughes, who envisions a harmonious democracy of the enhanced and the unenhanced. Agar argues that the outcomes of radical enhancement could be darker than the rosy futures described by these thinkers. The most dramatic means of enhancing our cognitive powers could in fact kill us; the radical extension of our life span could eliminate experiences of great value from our lives; and a situation in which some humans are radically enhanced and others are not could lead to tyranny of posthumans over humans.

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.

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)

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.

Increasingly the body is a possession that does not belong to us. It is bought and sold, bartered and stolen, marketed wholesale or in parts. The professions - especially reproductive medicine, transplant surgery, and bioethics but also journalism and other cultural specialists - have been pliant partners in this accelerating commodification of live and dead human organisms. Under the guise of healing or research, they have contributed to a new 'ethic of parts' for which the divisible body is severed from (...) the self, torn from the social fabric, and thrust into commercial transactions -- as organs, secretions, reproductive capacities, and tissues -- responding to the dictates of an incipiently global marketplace. Breaking with established approaches which prioritize the body as 'text', the chapters in this book examine not only images of the body-turned-merchandise but actually existing organisms considered at once as material entities, semi-magical tokens, symbolic vectors and founts of lived experience. The topics covered range from the cultural disposal and media treatment of corpses, the biopolitics of cells, sperm banks and eugenics, to the international trafficking of kidneys, the development of 'transplant tourism', to the idioms of corporeal exploitation among prizefighters as a limiting case of fleshly commodity. This insightful and arresting volume combines perspectives from anthropology, law, medicine, and sociology to offer compelling analyses of the concrete ways in which the body is made into a commodity and how its marketization in turn remakes social relations and cultural meanings.

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)

I argue that at least one of the following propositions is true: the human species is very likely to become extinct before reaching a ’posthuman’ stage; any posthuman civilization is extremely unlikely to run a significant number of simulations of its evolutionary history ; we are almost certainly living in a computer simulation. It follows that the belief that there is a significant chance that we shall one day become posthumans who run ancestor-simulations is false, unless we are currently living (...) in a simulation. I discuss some consequences of this result. (shrink)

Philosophers often characterize discourse in general as aiming at some sort of convergence (in beliefs, plans, dispositions, feelings, etc.), and many views about aesthetic discourse in particular affirm this thought. I argue that a convergence norm does not govern aesthetic discourse. The conversational dynamics of aesthetic discourse suggest that typical aesthetic claims have directive force. I distinguish between dynamic and illocutionary force and develop related theories of each for aesthetic discourse. I argue that the illocutionary force of aesthetic utterances is (...) typically invitational because its dynamic force is influenced by a ‘communal’ norm. I draw on dynamic pragmatics to develop a formal account of this dynamic force that explains why invitation has pride of place in aesthetic conversation. It turns out that the end of aesthetic discourse is not convergence but a distinctive form of community, a kind of harmony of individuality, that is compatible with aesthetic disagreement. If this is right, then convergence theories of aesthetic and normative discourse, and of conversation in general, need to be revised. (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)

_Anthropic Bias_ explores how to reason when you suspect that your evidence is biased by "observation selection effects"--that is, evidence that has been filtered by the precondition that there be some suitably positioned observer to "have" the evidence. This conundrum--sometimes alluded to as "the anthropic principle," "self-locating belief," or "indexical information"--turns out to be a surprisingly perplexing and intellectually stimulating challenge, one abounding with important implications for many areas in science and philosophy. There are the philosophical thought experiments and paradoxes: (...) the Doomsday Argument; Sleeping Beauty; the Presumptuous Philosopher; Adam & Eve; the Absent-Minded Driver; the Shooting Room. And there are the applications in contemporary science: cosmology ; evolutionary theory ; the problem of time's arrow ; quantum physics ; game-theory problems with imperfect recall ; even traffic analysis. _Anthropic Bias_ argues that the same principles are at work across all these domains. And it offers a synthesis: a mathematically explicit theory of observation selection effects that attempts to meet scientific needs while steering clear of philosophical paradox. (shrink)

According to one understanding of the problem of dirty hands, every case of dirty hands is an instance of moral conflict, but not every instance of moral conflict is a case of dirty hands. So, what sets the two apart? The dirty hands literature has offered widely different answers to this question but there has been relatively little discussion about their relative merits as well as challenges. In this paper I evaluate these different accounts by making clear which understanding of (...) concept distinctness underlies them and which of them is, ultimately, the most plausible one in the case of dirty hands and ordinary moral conflict. In order to do so, I will borrow from the terminology employed in recent debates in the philosophy of evil which have tackled a similar problem to the one at hand, i.e. defining what sets evil apart from ordinary wrongdoing. Here it has been argued that concepts could be distinct in three ways: they can have a quantitative difference, a strong qualitative or a moderate qualitative difference. I conclude that the most convincing definition of dirty hands draws a moderate qualitative distinction between ordinary moral conflict according to which dirty hands are those moral conflicts that involve a serious violation or betrayal of a core moral value.

Survivors of trauma commonly report feeling as though a part of themselves has died. This article provides a theoretical interpretation of this phenomenon, drawing on Waldenfels' notion of the split self. We argue that trauma gives rise to an explicit tension between the lived and corporeal body which is so profoundly distressing that it can be experienced by survivors as the death of part of oneself. We explore the ways in which this is manifest in the posttraumatic phenomena of dissociation; (...) indescribability; and the fragmentation and repetition of time. Acknowledging that the traumatic loss of part of oneself involves significant grief, we then consider whether the bereavement literature might be helpfully applied. We focus specifically upon the continuing bonds model, which emphasizes an ongoing and meaningful relationship with the deceased through an active process of memorializing. In considering how this might be appropriated to the death of the self in trauma, we suggest that the development of an intrapersonal relationship between parts lost and living might, over time, offer a unique way in which to adapt to loss and approach the future.
