In this paper, we consider how certain longstanding philosophical questions about mental representation may be answered on the assumption that cognitive and perceptual systems implement hierarchical generative models, such as those discussed within the prediction error minimization framework. We build on existing treatments of representation via structural resemblance, such as those in Gładziejewski :559–582, 2016) and Gładziejewski and Miłkowski, to argue for a representationalist interpretation of the PEM framework. We further motivate the proposed approach to content by arguing that it (...) is consistent with approaches implicit in theories of unsupervised learning in neural networks. In the course of this discussion, we argue that the structural representation proposal, properly understood, has more in common with functional-role than with causal/informational or teleosemantic theories. In the remainder of the paper, we describe the PEM framework for approximate Bayesian inference in some detail, and discuss how structural representations might arise within the proposed Bayesian hierarchies. After explicating the notion of variational inference, we define a subjectively accessible measure of misrepresentation for hierarchical Bayesian networks by appeal to the Kullbach–Leibler divergence between posterior generative and approximate recognition densities, and discuss a related measure of objective misrepresentation in terms of correspondence with the facts.

Recent work on rationality has been increasingly attentive to “coherence requirements”, with heated debates about both the content of such requirements and their normative status (e.g., whether there is necessarily reason to comply with them). Yet there is little to no work on the metanormative status of coherence requirements. Metaphysically: what is it for two or more mental states to be jointly incoherent, such that they are banned by a coherence requirement? In virtue of what are some putative requirements genuine (...) and others not? Epistemologically: how are we to know which of the requirements are genuine and which aren’t? This paper tries to offer an account that answers these questions. On my account, the incoherence of a set of attitudinal mental states is a matter of its being (partially) constitutive of the mental states in question that, for any agent that holds these attitudes jointly, the agent is disposed, when conditions of full transparency are met, to give up at least one of the attitudes.

Research suggests that interventions involving extensive training or counterconditioning can reduce implicit prejudice and stereotyping, and even susceptibility to stereotype threat. This research is widely cited as providing an “existence proof” that certain entrenched social attitudes are capable of change, but is summarily dismissed—by philosophers, psychologists, and activists alike—as lacking direct, practical import for the broader struggle against prejudice, discrimination, and inequality. Criticisms of these “debiasing” procedures fall into three categories: concerns about empirical efficacy, about practical feasibility, and about the (...) failure to appreciate the underlying structural-institutional nature of discrimination. I reply to these criticisms of debiasing, and argue that a comprehensive strategy for combating prejudice and discrimination should include a central role for training our biases away. (shrink)

Response-dependence theories have historically been very popular in aesthetics, and aesthetic response-dependence has motivated response-dependence in ethics. This chapter closely examines the prospects for such theories. It breaks this category down into dispositional and fittingness strands of response-dependence, corresponding to descriptive and normative ideal observer theories. It argues that the latter have advantages over the former but are not themselves without issue. Special attention is paid to the relationship between hedonism and response-dependence. The chapter also introduces two aesthetic properties that (...) lead to wrong kinds of reasons problems for aesthetic response-dependence: insightfulness and the capacity to change one’s perspective. These properties do not have obvious parallels in the ethical domain, and so present an obstacle for response-dependence even in aesthetics. The chapter ends by examining replies on behalf of the response-dependence theorist, ultimately suggesting that a restricted form of response-dependence is the most promising way forward for fans of such theories.

This book explores how our minds represent things in the world, asking whether these representations necessarily have the structure of propositions about the world. The hope is that this will lead towards a more complete understanding of the puzzle of intentionality -- how it is that our minds make contact with the world.

In this paper, I argue that theories of perception that appeal to Helmholtz’s idea of unconscious inference (“Helmholtzian” theories) should be taken literally, i.e. that the inferences appealed to in such theories are inferences in the full sense of the term, as employed elsewhere in philosophy and in ordinary discourse. -/- In the course of the argument, I consider constraints on inference based on the idea that inference is a deliberate acton, and on the idea that inferences depend on the (...) syntactic structure of representations. I argue that inference is a personal-level but sometimes unconscious process that cannot in general be distinguished from association on the basis of the structures of the representations over which it’s defined. I also critique arguments against representationalist interpretations of Helmholtzian theories, and argue against the view that perceptual inference is encapsulated in a module. (shrink)

We situate the debate on intentionality within the rise of cognitive neuroscience and argue that cognitive neuroscience can explain intentionality. We discuss the explanatory significance of ascribing intentionality to representations. At first, we focus on views that attempt to render such ascriptions naturalistic by construing them in a deflationary or merely pragmatic way. We then contrast these views with staunchly realist views that attempt to naturalize intentionality by developing theories of content for representations in terms of information and biological function. (...) We echo several other philosophers by arguing that these theories over-generalize unless they are constrained by a theory of the functional role of representational vehicles. This leads to a discussion of the functional roles of representations, and how representations might be realized in the brain. We argue that there’s work to be done to identify a distinctively mental kind of representation. We close by sketching a way forward for the project of naturalizing intentionality. This will not be achieved simply by ascribing the content of mental states to generic neural representations, but by identifying specific neural representations that explain the puzzling intentional properties of mental states.

Discussions of aesthetic reasons and normativity are becoming increasingly popular. This piece outlines six basic questions about aesthetic reasons, normativity, and value and discusses the space of possible answers to these questions. I divide the terrain into two groups of three questions each. First are questions about the shape of aesthetic reasons: what they favour, how strong they are, and where they come from. Second are relational questions about how aesthetic reasons fit into the wider normative landscape: whether they are (...) distinctive, what their normative status is, and how they interact with each other and with non-aesthetic reasons. This piece aims to provide a taxonomy to clarify and organise the burgeoning literature and to make a few concrete suggestions for avenues of future research. (shrink)

In order for the so-called strengthened impairment argument to succeed, it must posit some reason R that causing fetal alcohol syndrome is immoral, one that also holds in cases of abortion. In formulating SIA, Blackshaw and Hendricks borrow from Don Marquis to claim that the reason R that causing FAS is immoral lies in the fact that it deprives an organism of a future like ours. I argue here that SIA fails to show that it is immoral to cause FAS (...) and abort fetuses that will not be born because it deprives them of an FLO. This is because fetuses that will not be born have no chance of having an FLO in the first place, so causing FAS for and aborting them cannot deprive them of one. I then consider three responses to my argument. I conclude that each fails. SIA does not accomplish its task of showing why it is immoral to impair fetuses that will not be born. Perhaps it can accomplish the task of showing why it is immoral to impair fetuses that will be born, but not without sacrificing at least some of its alleged significance. (shrink)

I provide an opinionated overview of the literature on the relationship of contextualism to knowledge norms for action, assertion, and belief. I point out that contextualists about ‘knows’ are precluded from accepting the simplest versions of knowledge norms; they must, if they are to accept knowledge norms at all, accept “relativized” versions of them. I survey arguments from knowledge norms both for and against contextualism, tentatively concluding that commitment to knowledge norms does not conclusively win the day either for contextualism (...) or for its rivals. But I also suggest that an antecedent commitment to contextualism about normative terms may provide grounds for suspicion about knowledge norms, and a debunking explanation of some of the data offered in favor of such norms.

This paper tries to do three things. First, it tries to make it plausible that correct rules of reasoning do not always preserve justification: in other words, if you begin with a justified attitude, and reason correctly from that premise, it can nevertheless happen that you’ll nevertheless arrive at an unjustified attitude. Attempts to show that such cases in fact involve following an incorrect rule of reasoning cannot be vindicated. Second, it also argues that correct rules of reasoning do not (...) even correspond to permissions of “structural rationality”: it is not always structurally permissible to base an attitude on other attitudes from which it follows by correct reasoning. Third, from these observations it tries to build a somewhat positive account of the correctness of rules of reasoning as a more sui generis notion irreducible to either justification or structural rationality. This account vindicates an important unity of theoretical and practical reasoning as well as a qualified version of the thesis that deductive logic supplies correct rules of reasoning. (shrink)

Adverbialist theories of thought such as those advanced by Hare and Sellars promise an ontologically sleek understanding of a variety of intentional states, but such theories have been largely abandoned due to the ‘many-property problem’. In an attempt to revitalize this otherwise attractive theory, in a series of papers as well as his recent book, Uriah Kriegel has offered a novel reply to the ‘many-property problem’ and on its basis he argues that ‘adverbialism about intentionality is alive and well’. If (...) true, Kriegel will have shown that the logical landscape has long been unnecessarily constrained. His key idea is that the many-property problem can be overcome by appreciating that mental states stand in the determinable–determinate relation to one another. The present paper shows that this relation can’t save adverbialism because it would require thinkers to think more thoughts than they need be thinking. (shrink)

Intersubjectivity refers to the variety of possible relations between perspectives. It is indispensable for understanding human social behaviour. While theoretical work on intersubjectivity is relatively sophisticated, methodological approaches to studying intersubjectivity lag behind. Most methodologies assume that individuals are the unit of analysis. In order to research intersubjectivity, however, methodologies are needed that take relationships as the unit of analysis. The first aim of this article is to review existing methodologies for studying intersubjectivity. Four methodological approaches are reviewed: comparative self-report, (...) observing behaviour, analysing talk and ethnographic engagement. The second aim of the article is to introduce and contribute to the development of a dialogical method of analysis. The dialogical approach enables the study of intersubjectivity at different levels, as both implicit and explicit, and both within and between individuals and groups. The article concludes with suggestions for using the proposed method for researching intersubjectivity both within individuals and between individuals and groups. (shrink)

Robotic warfare has now become a real prospect. One issue that has generated heated debate concerns the development of ‘Killer Robots’. These are weapons that, once programmed, are capable of finding and engaging a target without supervision by a human operator. From a conceptual perspective, the debate on Killer Robots has been rather confused, not least because it is unclear how central elements of these weapons can be defined. Offering a precise take on the relevant conceptual issues, the article contends (...) that Killer Robots are best seen as executors of targeting decisions made by their human programmers. However, from a normative perspective, the execution of targeting decisions by Killer Robots should worry us. The article argues that what is morally bad about Killer Robots is that they replace human agency in warfare with artificial agency, a development which should be resisted. Finally, the article contends that the issue of agency points to a wider problem in just war theory, namely the role of moral rights in our normative reasoning on armed conflict. (shrink)

Despite increasing prominence, ‘ought’-contextualism is regarded with suspicion by most metaethicists. As I’ll argue, however, contextualism is a very weak claim, that every metaethicist can sign up to. The real controversy concerns how contextualism is developed. I then draw an oft-overlooked distinction between “parochial” contextualism—on which the contextually-relevant standards are those that the speaker, or others in her environment, subscribe to—and “aspirational” contextualism—on which the contextually-relevant standards are the objective standards for the relevant domain. However, I argue that neither view (...) is acceptable. I suggest an original compromise: “ecumenical contextualism”, on which some uses of ‘ought’ are parochial, others aspirational. Ecumenical contextualism is compatible with realism or antirealism, but either combination yields interesting results. And though it’s a cognitivist view, it is strengthened by incorporating an expressivist insight: for robustly normative usages of ‘ought’, the contextually-relevant standards must be endorsed by the speaker.

Dispositional theories of colour have been attacked by McGinn and others on the ground that ‘Colours do not look like dispositions’. Langsam has argued that on the contrary they do, in ‘Why Colours Do Look Like Dispositions’, The Philosophical Quarterly, 50 , pp. 68–75. I make three claims. First, neither side has made its case. Secondly, it is true, at least on one interpretation, that colours do not look like dispositions. Thirdly, this does not show that dispositionalism about colours is (...) false. (shrink)

An overview of the hedonistic theory of wellbeing.

Intentionalism about demonstratives is the view that the referent of a demonstrative is determined solely by the speaker's intentions. Intentionalists can disagree about the nature of these intentions, but are united in rejecting the relevance of other factors, such as the speaker's gestures, her gaze, and any facts about the addressee or the audience. In this paper, I formulate a particular version of this view, and I defend it against six objections, old and new.

This paper is a critique of Norman Daniels' and James Sabin's ‘Accountability for Reasonableness’ framework for making priority-setting decisions in health care in the face of widespread disagreement about values. Accountability for Reasonableness has been rapidly gaining worldwide acceptance, arguably to the point of becoming the dominant paradigm in the field of health policy. The framework attempts to set ground rules for a procedure that ensures that whatever decisions result will be fair, reasonable, and legitimate to the extent that even (...) those who would be adversely affected will have reason to abide by them. I argue that the framework's four conditions are inadequate to this task. While we certainly require a fair and legitimate procedure for making priority setting decisions in health care despite a lack of consensus on relevant ethical and political issues, we must significantly revise the four conditions, and we cannot avoid facing our substantive disagreements head on if we hope to arrive at decisions that would (and should) be acceptable to everyone. I offer two suggestions. First, there is need for greater public involvement in all stages of deliberation. Second, we should give up on the idea that we can simplify the task of democratic deliberation by disallowing particular kinds or reasons and types of reasoning. Reasons of all kinds should be on the table, but then should be judged on their merits, such as consistency, plausibility and explanatory power, without any regard for their alleged sources of authority.

This paper presents a formal account of how to determine the discourse relations between propositions introduced in a text, and the relations between the events they describe. The distinct natural interpretations of texts with similar syntax are explained in terms of defeasible rules. These characterise the effects of causal knowledge and knowledge of language use on interpretation. Patterns of defeasible entailment that are supported by the logic in which the theory is expressed are shown to underly temporal interpretation.

This essay examines a recent line of thought in aesthetics that challenges realist-leaning aesthetic theories. According to this line of thought, aesthetic diversity and disagreement are good, and our aesthetic judgments, responses, and attachments are deeply personal and even identity-constituting. These facts are further used to support anti-realist theories of aesthetic normativity. I aim to achieve two goals: (1) to disentangle arguments concerning diversity, disagreement, and personality; and (2) to offer realist-friendly replies to all three.

There have been many readings of Mead's work, and this paper proposes yet another: Mead, theorist of the social act. It is argued that Mead's core theory of the social act has been neglected, and that without this theory, the concept of taking the attitude of the other is inexplicable and the contemporary relevance of the concept of the significant symbol is obfuscated. The paper traces the development of the social act out of Dewey's theory of the act. According to (...) Mead, Dewey's theory does not sufficiently account for consciousness. Grappling with this problematic leads Mead to several key ideas, which culminate in his theory of the social act. The social act and taking the attitude of the other are then illustrated by the analysis of a game of football. The interpretation presented has two novel aspects: first, symbolisation arises not simply through self taking the attitude of the other, but through the pairing of this attitude with the complementary attitude in self; second, self is able to take the attitude of the other to the extent that self has in actuality or in imagination previously been in the social position of the other. From this standpoint the key issue is how the attitude of self and other become integrated. New directions for empirical research, aimed at advancing this question are outlined. Finally, the paper shows how the social act can contribute to our contemporary concerns about the nature of the symbolic. (shrink)

Many philosophers believe that truth is grounded: True propositions depend for their truth on the world. Some philosophers believe that truth’s grounding has implications for our ontology of time. If truth is grounded, then truth supervenes on being. But if truth supervenes on being, then presentism is false since, on presentism, e.g., that there were dinosaurs fails to supervene on the whole of being plus the instantiation pattern of properties and relations. Call this the grounding argument against presentism. Many presentists (...) claim that the grounding argument fails because, despite appearances, supervenience is compatible with presentism. In this paper, I claim that the grounding argument fails because, despite appearances, truth’s grounding gives the presentist no compelling reason to adopt the sort of supervenience principle at work in the grounding argument. I begin by giving two precisifications of the grounding principle: truthmaking and supervenience. In Sect. 2, I give the grounding argument against presentism. In Sect. 3, I argue that we should distinguish between eternalist and presentist notions of grounding; once this distinction is in hand, the grounding argument is undercut. In Sect. 4, I show how the presentist’s notion of grounding leads to presentist-friendly truthmaking and supervenience principles. In Sect. 5, I address some potential objections. (shrink)

At the heart of John Broome’s research program in the philosophy of normativity is a distinction between reasons, on one hand, and requirements of rationality, on the other. I am a friend of Broome’s view that this distinction is deep and important, and that neither notion can be analyzed in terms of the other. However, I also think there are major challenges that this view is yet to meet. In the first part of the paper, I’ll raise four such challenges, (...) and programmatically indicate how I think such challenges might be headed off. In the second part of the paper, I’ll discuss a third normative notion that Broome is interested in: that of (rules of) correct reasoning. On Broome’s view, correct reasoning is closely tied to requirements of rationality. More particularly, every rule of correct reasoning corresponds to a “basing permission”, which states that it’s rationally permissible to base one attitude on one or more other attitudes. I’ll argue that this proposal can’t be made to work. If I’m right, this suggests that the same kind of pulling-apart that Broome has effected so persuasively with respect to reasons and requirements of rationality needs to be effected again to separate rules of correct reasoning from both of those other categories.

: The debate over when medical research may be performed in developing countries has steered clear of the broad issues of social justice in favor of what seem more tractable, practical issues. A better approach will reframe the question of justice in international research in a way that makes explicit the links between medical research, the social determinants of health, and global justice.

An approach to implementing variational Bayesian inference in biological systems is considered, under which the thermodynamic free energy of a system directly encodes its variational free energy. In the case of the brain, this assumption places constraints on the neuronal encoding of generative and recognition densities, in particular requiring a stochastic population code. The resulting relationship between thermodynamic and variational free energies is prefigured in mind–brain identity theses in philosophy and in the Gestalt hypothesis of psychophysical isomorphism.

Hendricks’ The Impairment Argument (TIA) claims that it is immoral to impair a fetus by causing it to have fetal alcohol syndrome (FAS). Since aborting a fetus impairs it to a greater degree than causing it to have FAS, then abortion is also immoral. In this article, I argue that TIA ought to be rejected. This is because TIA can only succeed if it explains why causing an organism to have FAS impairs it to a morally objectionable degree, entails that (...) abortion impairs an organism to a morally objectionable and greater degree than causing FAS, and satisfies The Impairment Principle’s ceteris paribus clause. In order to do all three things, TIA must presuppose some theory of well-being. Even then, no theory of well-being accomplishes all three tasks that TIA must in order to succeed. However, even if this is false and TIA can meet all three objectives by presupposing some theory of well-being, it would not do very much to advance the debate about the morality of abortion. As I argue, TIA would essentially restate well-established arguments against abortion based on whatever theory of well-being it must presuppose in order to be successful. (shrink)

We analyse the tensions in a hybrid collaboration and how these are mitigated using boundary-spanning community impact, leading to compatibility between distinctive institutional logics. Our qualitative longitudinal study undertaken during 2011–2016 involved reviewing literature and archival data, key informant interviews, workshop and focus groups. We analysed common themes within the data, relating to our two research questions concerning how and why hybrids collaborate, and how resulting tensions are mitigated. The findings suggest a viable model of service delivery termed hybridized collaboration (...) in which the inherent tensions from different institutional logics do not prevent success. Paradoxically, multiple logics are a basis for the partnership’s existence, but the ability to achieve different and occasionally conflicting aims simultaneously can be difficult, resulting in tensions. We offer two novel insights. First, we highlight how social enterprise hybrids collaborate locally and in multi-organizational relationships. We found that the initial opportunity to collaborate was catalysed by the existence of shared objectives. Pre-existing relationships between organizations, and the existence of synergistic capabilities also influence the choice of partners. Secondly, we identify how tensions arise, and are mitigated via several factors including the pre-existing relationships, allowing for regular “spaces of negotiation” between collaborators, the shared social mission, community social impact, the resulting public relations, and shared resources and knowledge.

Epistemologists typically assume that the acquisition of knowledge from testimony is not threatened at the stage at which audiences interpret what proposition a speaker has asserted. Attention is instead typically paid to the epistemic status of a belief formed on the basis of testimony that it is assumed has the same content as the speaker’s assertion. Andrew Peet has pioneered an account of how linguistic context sensitivity can threaten the assumption. His account locates the threat in contexts in which an (...) audience’s evidence under-determines which proposition a speaker is asserting. I argue that Peet’s epistemic uncertainty account of the threat is mistaken and I propose an alternative. The alternative locates the threat in contexts that provide factors that give audiences a mistaken psychological certainty or confidence that a speaker has asserted a proposition she has not.

This chapter focuses on what’s novel in the perspective that the prediction error minimization (PEM) framework affords on the cognitive-scientific project of explaining intelligence by appeal to internal representations. It shows how truth-conditional and resemblance-based approaches to representation in generative models may be integrated. The PEM framework in cognitive science is an approach to cognition and perception centered on a simple idea: organisms represent the world by constantly predicting their own internal states. PEM theories often stress the hierarchical structure of (...) the generative models they posit. The novel explanatory power of the PEM account derives largely from the way in which pairs of generative and recognition models interact. “Predictive coding” refers to an encoding strategy in which predicted portions of an input signal are subtracted from the actual signal received, so that only the difference between the two is passed as output to the next stage of information processing.

I outline and defend two egalitarian theories, which yield distinctive and, I argue, complementary answers to why health-related inequalities matter: a brute luck egalitarian view, according to which inequalities due to unchosen, differential luck are bad because unfair, and a social egalitarian view, according to which inequalities are bad when and because they undermine people’s status as equal citizens. These views identify different objects of egalitarian concern: the brute luck egalitarian view directs attention to health-related well-being, while social egalitarianism focuses (...) on health-related capabilities that are central to a person’s status as a citizen. I argue that both views are correct and should jointly guide priority-setting in health. (shrink)

Blackshaw and Hendricks recently developed a strengthened version of the impairment argument (SIA) that imports Marquis’ account of the wrongness of abortion. I then argued that if SIA imports Marquis’ account, then it restates Marquis’ position and thus is not very significant. In turn, Blackshaw and Hendricks explained why they take SIA to be importantly different from Marquis’ account. I have two aims in this response. First, I reconstruct Blackshaw and Hendricks’ arguments for the claim that SIA is importantly different (...) from Marquis’ account. Second, I argue that SIA is not importantly different from Marquis’ account in the respect that Blackshaw and Hendricks take it to be. (shrink)

It has become an intellectual commonplace to claim that we have entered the era of 'postmodernity'. Three themes are embraced in this claim the poststructurist critique by Foucault, Derrida and others of the philosophical heritage of the Enlightenment the supposed impasse of High Modern art and its replacement by new artistic forms and the alleged emergence of 'post-industrial' societies whose structures are beyond the ken of Marx and other theorists of industrial capitalism. Against Postmodernism takes issue with all these themes. (...) It challenges the idealist irrationalism of post-structuralism. It questions the existence of any radical break separating allegedly Postmodern from Modern art. And it denies that recent socio-economic developments represent any fundamental shift from classical patterns of capital accumulation. Drawing on philosophy and history, Against Postmodernism takes issue also with some of the most forthright critics of postmodernism -- Jurgen Habermas and Fredric Jameson, for example. But it is most distinctive in that it offers a historical reading of the theories of such currently fashionable thinkers as Baudrillard and Lyotard. Postmodernism, Alex Callinios argues, reflects the disappointed revolutionary generation of '68, and the incorporation of many of its members into the porfessional and managerial 'new middle class'. It is best read as a symptom of political frustration and social mobility rather than as a significant intellectual or cultural phenomenon in its own right. (shrink)

I argue here that the impairment principle requires clarification. It needs to explain what makes one impairment greater than another, otherwise we will be unable to make the comparisons it requires, the ones that enable us to determine whether b really is a greater impairment than a, and as a result, whether causing b is immoral because causing a is. I then develop two of what I think are the most natural accounts of what might make one impairment greater than (...) another. The quantitative understanding of greater impairment is problematic because it leaves the impairment principle vulnerable to counterexamples; just because impairment b impairs a larger number of abilities or the same number of abilities but for a longer period or to a higher degree does not mean that b is a greater impairment than a. The qualitative understanding of greater impairment is problematic because it does not explain examples of greater impairment used in the literature, means that an abortion is always a qualitatively more severe impairment than causing fetal alcohol syndrome regardless of how the organism is affected, and/or entails that lethal impairment is always greater than nonlethal impairment.

The 2016 CIOMS International ethical guidelines for health‐related research involving humans states that ‘health‐related research should form an integral part of disaster response’ and that, ‘widespread emergency use [of unproven interventions] with inadequate data collection about patient outcomes must therefore be avoided’ (Guideline 20). This position is defended against two lines of criticism that emerged during the 2014 Ebola outbreak. One holds that desperately ill patients have a moral right to try unvalidated medical interventions (UMIs) and that it is therefore (...) unethical to restrict access to UMIs to the clinical trial context. The second holds that clinical trials in contexts of high‐mortality diseases are morally suspect because equipoise does not exist between a standard of care that offers little prospect of clinical benefit and a UMI that might offer some clinical advantage.

In what circumstances is it legitimate to use force? How should force be used? These are two of the most crucial questions confronting world politics today. The Just War tradition provides a set of criteria which political leaders and soldiers use to defend and rationalize war. This book explores the evolution of thinking about just wars and examines its role in shaping contemporary judgements about the use of force, from grand strategic issues of whether states have a right to pre-emptive (...) self-defence, to the minutiae of targeting. Bellamy maps the evolution of the Just War tradition, demonstrating how it arose from a myriad of sub-traditions, including scholasticism, the holy war tradition, chivalry, natural law, positive law, Erasmus and Kant's reformism, and realism from Machiavelli to Morgenthau. He then applies this tradition to a range of contemporary normative dilemmas related to terrorism, pre-emption, aerial bombardment and humanitarian intervention. (shrink)

In this paper, we offer a novel analysis of presuppositions, paying particular attention to the interaction between the knowledge resources that are required to The analysis has two main features. First, we capture an analogy between presuppositions, anaphora and scope ambiguity (cf. van der Sandt 1992), by utilizing semantic under-specification (c£ Reyle 1993). Second, resolving this underspecification requires reasoning about how the presupposition is rhetorically connected to the discourse context. This has several consequences. First, since pragmatic information plays a role (...) in computing the rhetorical relation, it also constrains the interpretation of presuppositions. Our account therefore provides a formal framework for analysing problematic data, which require pragmatic reasoning. Second, binding presuppositions to the context via rhetorical links replaces accommodating them, in the sense of adding them to the context (cf. Lewis 1979). The treatment of presupposition is thus generalized and integrated into the discourse update procedure. We formalize this approach in SDRT (Asher 1993; Lascarides & Asher 1993), and demonstrate that it provides a rich framework for interpreting presuppositions, where semantic and pragmatic constraints are integrated.

What must linguistic knowledge be like if it is to explain our capacity to use language? All linguists and philosophers of language presuppose some answer to this critical question, but all too often the presupposition is tacit. In this collection of sixteen previously unpublished essays, a distinguished international line-up of philosophers and linguists address a variety of interconnected themes concerning our knowledge of language.

It is commonly assumed that ‘ought’ implies ‘can’, that is, that if we ought to do something, then it must be the case that we can do it. It is a frequent quip about this thesis that any account must specify three things: what is meant by the ‘ought’, what is meant by the ‘implies’, and what is meant by the ‘can’. Something is missed, though, when we state the thesis in its shortened, three-word form. We overlook what it means (...) to do something. It is, I think, not mere coincidence that nobody has discussed this issue: It is very difficult to specify what it means to do something in the relevant sense. This paper is devoted to fleshing out one way of doing something that is a problem for the thesis. (shrink)

Our moral convictions cannot, on the face of it, count in evidence against scientific claims with which they happen to conflict. Moral anti-realists of whatever stripe can explain this easily: science is immune to moral refutation because moral discourse is defective as a trustworthy source of true and objective judgments. Moral realists, they can add, are unable to explain this immunity. After describing how anti-realists might implement this reasoning, the paper argues that the only plausible realist comeback turns on the (...) practical nature of moral reasoning. This comeback, however, places significant constraints on the structure of evidence for moral judgments. These constraints cannot be met by coherentist defenders of reflective-equilibrium methodology or by anyone sympathetic to bottom-up, case-driven foundationalism, including those who claim we have perceptual or perception-like access to moral truths. Unfortunately for realists in these categories, alternative realism-friendly accounts of science’s apparent moral immunity are unpromising. These neither explain nor explain away our unwillingness to infer an is from an ought, as Hume might have put it. Science’s apparent immunity to moral refutation therefore poses a serious problem for any realist unhappy with top-down, theory-driven conceptions of the structure of moral evidence. (shrink)

English has plural terms as well as singular terms. But our standard formal languages, e.g., the predicate calculus, feature only singular terms. How can the plural idiom be formalized?‘Changing the subject’ is by far the most common plurals strategy among both philosophers and linguists: a plural term is replaced by a singular term standing for some complex object that ‘contains’ the individuals to which the plural term alludes. For example, one might simply replace ‘A, B imply C’ with ‘{A, B} (...) implies [singular] C’. We uncover a surprising variety of ways to change the subject, of ever‐increasing complexity and ingenuity. Our question is whether any can made to work. (shrink)

In the last decade there has been a torrent of work at the intersection of philosophy and linguistics on predicates of personal taste, subjective expressions like fun and tasty that are used to express opinions rather than matters of fact. In each section of this paper I discuss a phenomenon that has been largely overlooked in the literature on PPTs. In Section 1, I identify a neglected experiential reading of these adjectives. All other theories of expressions like fun take them (...) to express some standing property, but distributional and compositional considerations suggest that the basic meaning of fun adjectives is experiential. In Section 2, I discuss the relation between fun claims relativized to particular experiencers and their unrelativized counterparts, arguing that previous theories fail to capture the evaluativity unique to the latter. Finally, I argue... (shrink)

This paper examines the concept of a 'standard of care' as it has been used in recent arguments over the ethics of international human-subjects research. It argues that this concept is ambiguous along two different axes, with the result that there are at least four possible standard of care arguments that have not always been clearly distinguished. As a result, it has been difficult to assess the implications of opposing standard of care arguments, to recognize important differences in their supporting (...) rationales, and even to locate the crux of the disagreement in some instances. The goal of the present discussion, therefore, is to disambiguate the concept of a 'standard of care' and to highlight the areas of genuine disagreement among different standards. In the end it is argued that one standard of care argument in particular is more complex than either its proponents or its critics may have recognized and that understanding this possibility opens up a potentially promising avenue of inquiry that remains to be carefully explored.

Going about our daily lives in an orderly manner requires us, once we are aware of them, to dismiss many metaphysical possibilities. We take it for granted that we are not brains in vats, or living in the Matrix, or in an extended dream. Call these things that we take for granted “anti-skeptical assumptions”. What should a reflective agent who believes these things think of these beliefs? For various reasons, it can seem that we do not have evidence for such (...) anti-skeptical assumptions. Are anti-skeptical assumptions, then, beliefs that one may rationally hold without evidence for them – indeed, even in the face of a positive judgment that one lacks evidence for them? I survey and criticize some prominent answers to this question, and then offer a positive view that blends externalism about evidence with a mild, qualified kind of pragmatism. The view I offer aims to do justice to the sense that anti-skeptical assumptions are evidentially groundless while also maintaining that one cannot rationally believe something that one judges oneself to lack sufficient evidence for.

This paper examines the role of equipoise in evaluating international research. It distinguishes two possible formulations of the equipoise requirement that license very different evaluations of international research proposals. The interpretation that adopts a narrow criterion of similarity between clinical contexts has played an important role in one recent controversy, but it suffers from a number of problems. An alternative interpretation that adopts a broader criterion of similarity does a better job of avoiding both exploitation of the brute fact of (...) social deprivation and the exploitation of needy populations for the benefit of more well-off populations. It also holds out the promise of reconciling the need to find interventions that can be employed in developing world contexts with the cluster of moral values that must constrain the way such research is carried out.

What is medicine? One obvious answer in the context of the contemporary clinical tradition is that medicine is the process of curing sick people. However, this “curative thesis” is not satisfactory, even when “cure” is defined generously and even when exceptions such as cosmetic surgery are set aside. Historian of medicine Roy Porter argues that the position of medicine in society has had, and still has, little to do with its ability to make people better. Moreover, the efficacy of medicine (...) for improving population health has been famously doubted by historians and epidemiologists. The curative thesis demands that we have mostly been stupid, duped, or staggeringly hopeful, given that medicine has not until recently offered more than a handful of effective cures. I suggest, in this article, that the core medical competence is neither to cure, nor to prevent, disease, but to understand and to predict it. I argue that this approach does a better job than the curative thesis at explaining why not all medicine is concerned with curative efforts and that it enjoys historical support from the ancient entanglement of prophecy and medicine and from the fact that medicine thrived for centuries with almost no effective cures and continues to thrive today in various forms that are mostly without curative efficacy. I suggest that this approach grounds a fairer approach to alternative, traditional, and other medical practices, as well as some fresh lessons for the development of mainstream medicine. (shrink)

Following a boom in investment and overinflated expectations in the 1980s, artificial intelligence entered a period of retrenchment known as the “AI winter.” With advances in the field of machine learning and the availability of large datasets for training various types of artificial neural networks, AI is in another cycle of halcyon days. Although medicine is particularly recalcitrant to change, applications of AI in health care have professionals in fields like radiology worried about the future of their careers and have (...) the public tittering about the prospect of soulless machines making life‐and‐death decisions. Medicine thus appears to be at an inflection point—a kind of Groundhog Day on which either AI will bring a springtime of improved diagnostic and predictive practices or the shadow of public and professional fear will lead to six more metaphorical weeks of winter in medical AI.

It follows from David Lewis's counterpart-theoretic analysis of modality and his counterfactual theory of causation that causal claims are relativized to a set of counterpart relations. Call this Shlewis's view. I show how Shlewis's view can provide attractively unified solutions to similar modal and causal puzzles. I then argue that Shlewis's view is better motivated, by his own lights, than the view Lewis actually held, and also better motivated than a similar approach which relativizes causal claims to sets of ‘contrast (...) events’.
