Some philosophers claim that emotions are, at best, hindrances to the discovery of evaluative truths, while others omit them entirely from their epistemology of value. I argue, however, that this is a mistake. Drawing an evaluative parallel with Frank Jackson’s Mary case, I show there is a distinctive way in which emotions epistemically enhance evaluative judgment. This is, in fact, a conclusion philosophers of emotion have been eager to endorse. However, after considering several influential proposals—such as the view that emotions (...) generate evaluative concepts, or the view that emotions justify evaluative beliefs on the model of perception—I conclude that the most promising contender is the notion that emotional experience acquaints us with evaluative properties.

This article addresses the challenge philosophical realism poses to the field of rhetoric by exploring the possibility of symbolic communion with nonhuman entities. As a matter of framing, I invoke Timothy Morton’s concept of the hyperobject to better understand the complexities of communicating with and about sublime nonhuman objects such as black holes. I then delineate how the stylistic modality of the weird best exploits the chasm between autonomous thingness and human presentation that is a primary source of consternation for (...) rhetorical realism. Finally, I draw from Kathe Koja’s novel The Cipher to reconsider a bizarre rhetoric of black holes which displays the omnipresent tension of accessible-alterity characteristic of the struggle to rhetorically breach the nonhuman world.

ABSTRACT Most theorists agree that our social order includes a distinctive legal dimension. A fundamental question is that of whether reference to specific legal phenomena always involves a commitment to a particular moral view. Whereas many philosophers advance the ‘positivist’ claim that any correspondence between morality and the law is just a function of political circumstance, natural law theorists insist that law is intrinsically moral. Each school claims the crucial advantage of consistency with our folk concept. Drawing on the notion (...) of dual character concepts, we develop a set of hypotheses about the intuitive relation between a rule’s moral and legal aspects. We then report a set of studies that conflict unexpectedly with the predictions by legal positivists. Intuitively, an evil rule is not a fully-fledged instance of law. (shrink)

In a recent article in this journal, David Faraci argues that the value of fairness can plausibly be appealed to in order to vindicate the view that consensual, mutually beneficial employment relationships can be wrongfully exploitative, even if employers have no obligation to hire or otherwise benefit those who are badly off enough to be vulnerable to wage exploitation. In this commentary, I argue that several values provide potentially strong grounds for thinking that it is at least sometimes better, morally (...) speaking, for employers to hire worse-off people at intuitively exploitative wages than to hire better-off people at intuitively fair wages. Rather than suggesting that hiring badly off people at intuitively exploitative wages is permissible, however, I suggest that this gives us reason to think that employers can be obligated to hire worse-off people rather than better-off people and to pay them nonexploitative wages.

Perceptual illusionism is the view that perceptual experience is, in general, radically illusory. That is, perceptual experience presents objects as having certain sensible properties and standing in certain sensible relations, but nothing in the subject’s environment has those properties or stands in those relations. This paper makes the case for perceptual illusionism by showing how a broad set of philosophical and scientific considerations converge to support illusionism about the full range of sensible properties and relations. After clarifying the illusionist thesis, (...) I set out the argument in three parts. First, I briefly make the case for an illusionist view of color. I then argue for illusionism about the spatial/temporal properties presented in experience on the assumption that some “radical” view of space (and/or time) is correct—that is, some view according to which nothing like our ordinary three-dimensional space (or four-dimensional spacetime) exists at the fundamental level. Finally, I argue that there is a strong case for illusionism even if all radical views turn out to be false. (shrink)

The demandingness of a moral prescription is generally understood exclusively in terms of the welfare costs involved in complying with that prescription. I argue that psychological difficulty is a second aspect of demandingness, whose relevance cannot be reduced to that of welfare costs. Appeal to psychological difficulty explains intuitive verdicts about the permissibility of favouring oneself over others, favouring loved ones over strangers, and favouring one’s short-term good over one’s long-term good. There are also significant implications for the morality of (...) addressing severe global poverty. (shrink)

This article argues that, in public and policy contexts, the ways in which many scientists talk about uncertainty in simulations of future climate change not only facilitates communications and cooperation between scientific and policy communities but also affects the perceived authority of science. Uncertainty tends to challenge the authority of chmate science, especially if it is used for policy making, but the relationship between authority and uncertainty is not simply an inverse one. In policy contexts, many scientists are compelled to (...) talk about uncertainty but do not wish to imply that uncertainty is a serious challenge to the authority of scientific knowledge or to its substantial use in policy making. "Boundary-ordering devices, " the contextual discursive attempts to reconcile uncertainty and authority in science, depend critically for their success on their "dual" interpretation: at a general level across a boundary and differently on either side of it. The authors empirically identify a range of such boundary-ordering devices in the climate field. (shrink)

This paper develops and defends a new argument against physicalist views of consciousness: the inconceivability argument. The argument has two main premises. First, it is not (ideally, positively) conceivable that phenomenal truths are grounded in physical truths. (For example, one cannot positively conceive of a situation in which someone has a vivid experience of pink wholly in virtue of the movements of colorless, insentient atoms.) Second, (ideal, positive) inconceivability is a guide to falsity. I attempt to show that the inconceivability (...) argument enjoys a significant advantage over the more familiar conceivability argument. One can reasonably endorse the inconceivability argument without endorsing the conceivability argument, but one cannot reasonably endorse the conceivability argument without also endorsing the inconceivability argument.

The question of what makes someone the same person through time and change has long been a preoccupation of philosophers. In recent years, the question of what makes ordinary or lay people judge that someone is—or isn’t—the same person has caught the interest of experimental psychologists. These latter, empirically oriented researchers have sought to understand the cognitive processes and eliciting factors that shape ordinary people’s judgments about personal identity and the self. Still more recently, practitioners within an emerging discipline, experimental (...) philosophical bioethics or “bioxphi”—the focus of this chapter—have adopted a similar aim and employed similar methodologies, but with two distinctive features: (a) a special concern for enhanced ecological validity in the examples and populations studied; and (b) an interest in contributing to substantive normative debates within the wider field of bioethics. Our aim in this chapter is to sample illustrative work on personal identity in bioxphi, explore how it relates to studies in psychology covering similar terrain, and draw out the implications of this work for matters of bioethical concern. In pursuing these issues, we highlight recent work in bioxphi that includes the perceived validity of advance directives following neurodegeneration, the right of psychologically altered study participants to withdraw from research, how drug addiction may cause one to be regarded by others as “a completely different person,” the effect of deep-brain stimulation on perceptions of the self, and the potential influence of moral enhancement interventions on intuitive impressions of a person’s character.

For a long time before the ‘climategate’ emails scandal of late 2009 which cast doubt on the propriety of science underpinning the Intergovernmental Panel on Climate Change (IPCC), attention to climate change science and policy has focused solely upon the truth or falsity of the proposition that human behaviour is responsible for serious global risks from anthropogenic climate change. This article places such propositional concerns in the perspective of a different understanding of the relationships between scientific knowledge and public policy (...) issues from the conventional ‘translation’ model, in which prior scientific research and understanding is communicated and translated into corresponding policies — or not, if it remains disputed and overly uncertain. Explaining some of the key contingencies and bases for uncertainty in IPCC climate projections and human influences, I show how social and technical analysis of climate science is not about denial of the scientific propositional claims at issue, but about understanding the conditional and essentially ambiguous epistemic character of any such knowledge, however technically sophisticated and robust it may be. Contrary to conventional wisdom, it is entirely plausible that existing scientific representations of climate change and its human causes may understate the risks induced by prevailing social-economic processes rather than exaggerate them. As the article shows, the public meanings given to climate science, and to ‘the climate problem’, and thus also the public culture which that knowledge is supposed to inform, are themselves already in key respects presumed and (attemptedly) imposed by the science and its framing. This gives rise to perverse effects on public readiness to take informed democratic responsibility for ‘the global climate problem’, and associated cross-cutting issues which existing scientific framings of public policy erase from view.

Political institutions can be transparent or secret. If they are transparent, then we have access to information about how agents act within them. If they are secret, then we do not have access to this information. The presence and extent of transparency has tremendous impact on how political institutions function. The purpose of this article is to offer a brief overview of what political philosophers have thus far had to say about transparency as it pertains to political institutions. In doing (...) so, I hope to connect philosophical questions about transparency to relevant social scientific work and to highlight areas where more work needs to be done. (shrink)

This article integrates arguments and evidence from my 2019 monograph Heart to Heart: How Your Emotions Affect Other People. The central claim is that emotions operate as processes of relation alignment that produce convergence, complementarity, or conflict between two or more people’s orientations to objects. In some cases, relation alignment involves strategic presentation of emotional information for the purpose of regulating other people’s behaviour. In other cases, emotions consolidate from socially distributed reciprocal adjustments of cues, signals, and emerging actions without (...) any explicit registration or communication of emotional meaning by parties to the exchange. The relation-alignment approach provides a fresh perspective on issues relating to emotion’s interpersonal, intragroup, and organizational functions and clarifies how emotions are regulated for social purposes.

Since its publication in 1965 _Political Argument_ has come to be recognized as occupying a key position in the revival of Anglo-American political philosophy. A number of the ideas introduced by Barry have become part of the standard vocabulary, such as the distinction between ideal-regarding and want-regarding principles and the division of principles into aggregative and distributive. _Political Argument_ provided the first precise analysis, still frequently cited, of the conception that political values have trade-off relations; the analysis of the notion (...) of the public interest has also enjoyed wide influence. For this long-awaited reprint, the author has prepared a substantial, new introductory essay in which he recounts the process of writing the book and sets it in the intellectual milieu of its time. He then offers extensive comments on the subsequent fate of some of the leading ideas and assesses the book in light of criticisms and later developments. Finally, Barry evaluates current approaches to political philosophy as they look today. This new edition of _Political Argument_ will interest political theorists, philosophers, economists, and a range of other scholars. Brilliant and incisive, it will engender discussion and debate from many quarters. (shrink)

Neuroscience was the basic science behind Freud's psychoanalytic theory and technique. He worked as a neurologist for 20 years before being aware that a new approach to understand complex diseases, namely the hysterias, was needed. Solms coined the term neuropsychoanalysis to affirm that neuroscience still belongs in psychoanalysis. The neuropsychoanalytic field has continued Freud's original ideas as stated in 1895. Developments in psychoanalysis that have been created or revised by the neuropsychoanalysis movement include pain/relatedness/opioids, drive, structural model, dreams, cathexis, and (...) dynamic unconscious. Neuroscience has contributed to the development of new psychoanalytic theory, such as Bazan's ( 2011 ) description of anxiety driven by unconscious intentions or “phantoms.” Results of adopting the “dual aspect monism” approach of idiographic psychoanalytic clinical observation combined with nomothetic investigation of related human phenomena include clarification and revision of theory, restoration of the scientific base of psychoanalysis, and improvement of clinical treatments. By imbricating psychoanalytic thinking with neuroscience, psychoanalysts are also positioned to make contributions to neuroscience research. Freud's original Project for a Scientific Psychology/Psychology for Neurologists can be carried forward in a way that moves psychoanalysis into the twenty-first century as a core contemporary science (Kandel, 1999 ). Neuroscience as the basic science of psychoanalysis both improves the field, and enhances its scientific and cultural status. (shrink)

Dominant social sciences approaches to complexity suggest that awareness of complexity in late-modern society comes from various recent scientific insights. By examining today’s plant and human genomics sciences, I question this from both ends: first suggesting that typical public culture was already aware of particular salient forms of complexity, such as limits to predictive knowledge (which are often denied by scientific cultures themselves); second, showing how up-to-date genomics science expresses both complexity and its opposites, predictive determinism and reductionism, as coexistent (...) representations of nature and scientific knowledge. I suggest we can understand this self-authored epistemic confusion in modern science by avoiding ‘the usual suspects’ – fading simpler discourses left over from previous scientific times; media oversimplifications; or the need to ‘simplify’ to essentials, for ignorant publics – and looking instead at the silent imaginations of extra-scientific reference groups reflected and projectively performed in scientific discourses-practices themselves. Thus contradictions of complex scientific understandings are systematically created by science’s own embodiment of epistemic commitments influenced by commercial cultures, and by imagined publics who are important new constructed objects of institutional scientific concerns – over authority and trust. New dimensions of complexity thus come alive through paying attention to neglected tacit dimensions of science–society interrelations. (shrink)

The central thesis of this paper is that fake news and related phenomena serve as defeaters for knowledge transmission via journalistic channels. This explains how they pose a threat to democracy; and it points the way to determining how to address this threat. Democracy is both intrinsically and instrumentally good provided the electorate has knowledge (however partial and distributed) of the common good and the means of achieving it. Since journalism provides such knowledge, those who value democracy have a reason (...) to protect it. Hostile agents, however, can undermine both the effectiveness of democratic decision-making and faith in democracy itself, by deliberately promulgating fake news and hyper-partisan views; moreover, these effects can come about unintentionally on social media. I conclude that we may need to change, not just the way we process information online, but also the informational environment in which we operate. (shrink)

It is morally negligent or reckless to believe without sufficient evidence. The foregoing proposition follows from a rule that is a modified expression of W. K. Clifford's ethics of belief. Clifford attempted to prove that it is always wrong to believe without sufficient evidence by advancing a doxastic counterpart to an act utilitarian argument. Contrary to various commentators, his argument is neither purely nor primarily epistemic, he is not a non-consequentialist, and he does not use stoicism to make his case. (...) Clifford's conclusion is a universal generalisation that is in a precarious position because of potential counterexamples. But the counterexamples do not preclude a rule against going beyond the available evidence and it is worthwhile making a moral case for such a rule. (shrink)

Discussions of diversity tend to paint a mixed picture of the practical and epistemic value of diversity. While there are expansive and detailed accounts of the value of cognitive diversity, explorations of identity diversity typically focus on its value as a source or cause of cognitive diversity. The resulting picture on which identity diversity only possesses a derivative practical and epistemic value is unsatisfactory and fails to account for some of its central epistemic benefits. In response, I propose that collective (...) virtue epistemology offers theoretical models that can further our understanding of the benefits of diversity. And I offer a case study to illustrate how this approach could be used to explore the logic of the identity diversity bonus. (shrink)

Not long ago, under the influence of Michel Foucault, one spoke of the conjunction of knowledge and power, but in this post-truth era power appears singularly uninterested in knowledge, even as the supporters of Donald Trump claim that he alone of all politicians speaks the truth. This essay proposes to examine the relations of power and knowledge under the present populist assault. This analysis begins in the work of Claude Lefort, who spoke of the separation of knowledge and power in (...) democracy’s symbolic regime, and is then counterposed to Ernesto Laclau’s understanding of ‘populist reason’ in order to explore the present torsion of this relation to the point where power can appear not just separated from, but opposed to knowledge. It will be argued that it is less a question of post-truth than of different forms of truth with different truth claims, borne by different imperatives, and tied to different forms of representation – truth claims that can, in relation to each other, be indifferent, complementary, or conflictual. With this in mind, the essay asks: what is the relation of the people to truth? Do those who claim to represent the people seek possession of a different kind of truth? What is the relation of populism to ideology? And what is populism’s relation to ‘post-modernism’? (shrink)

When we have asked Hadza whether married couples should live with the family of the wife (uxorilocally) or the family of the husband (virilocally), we are often told that young couples should spend the first years of a marriage living with the wife’s family, and then later, after a few children have been born, the couple has more freedom—they can continue to reside with the wife’s kin, or else they could join the husband’s kin, or perhaps live in a camp (...) where there are no close kin. In this paper, we address why shifts in kin coresidence patterns may arise in the later years of a marriage, after the birth of children. To do so, we model the inclusive fitness costs that wives might experience from leaving their own kin and joining their husband’s kin as a function of the number of children in their nuclear family. Our model suggests that such shifts should become less costly to wives as their families grow. This simple model may help explain some of the dynamics of postmarital residence among the Hadza and offer insight into the dynamics of multilocal residence, the most prevalent form of postmarital residence among foragers.

Teleosemantics explains mental representation in terms of etiological history: a mental state’s representational contents are the result of natural selection, or some other selection process. Critics have argued that the “swampman” thought experiment poses a counterexample to teleosemantics. In several recent papers, Papineau has argued that a merely possible swampman cannot serve as a counterexample to teleosemantics, but has acknowledged that actual swampmen would pose a problem for teleosemantics. In this paper, I argue that there are real-world cases of swampman-like (...) representation, in the form of functional tetrachromacy. People with functional tetrachromacy are born with four types of cones in each eye, rather than the usual three, and as a result can represent a wider variety of colors than the average person. I argue that the functional tetrachromat’s additional color representations are not the result of a selection process. Functional tetrachromacy is therefore a real-world case of mental representation without an etiological history, and therefore poses a genuine counterexample to teleosemantics. (shrink)

This article catalogs social processes contributing to construction of emotions across three time-scales, covering: natural selection; ontogenesis; and moment-by-moment transactions. During human evolution, genetic and cultural influences operate interdependently, not as separate forces working against each other. Further, leaving infants’ environment-open serves adaptive purposes. During ontogenesis, cultural socialization affects emotion development in various ways, not all of which depend on internalization of cultural meanings as emphasized in some earlier social constructionist accounts. Construction also operates over the moment-by-moment time-scale of real-time (...) interpersonal interactions, as emotions adjust to the constraints and affordances of immediate cultural environments. Claims that emotions are constructed, and that social processes contribute to their construction, are no longer contestable. Now the project is to specify how these processes operate and what materials they use. (shrink)

This abridgement of _Reflections on the Revolution in France_ preserves the dynamism of Edmund Burke’s polemic while excising a number of detail-laden passages that may be of less interest to modern readers. Brian R. Clack’s introduction offers a compelling overview of the text and explores the consistency and coherence of Burke’s views on revolution. Burke’s critique of revolutionary politics is illuminated further by the extensive supplementary materials collected in a number of themed appendices.

Drawing on interviews and observational work with practicing U.K. plant scientists, this article uses Michel Callon's work as a tool to explore the issue of collaboration between academic science and business, in particular, calls by the Biotechnology and Biological Sciences Research Council for a return to “public good” plant science. In an article titled “Is Science a Public Good?” Callon contributed to the debate about the commercialization of science by suggesting that commercialization and the public good need not be incompatible. (...) Moving away from arguments that center on the effects of business involvement in science, he suggested that analysts use another model, centered on “diversity.” This model allows us to ask what society might want from science, what public good science might look like, and how public good science can be ensured while also recognizing that science cannot be easily separated from the market.

We live in a world of gross inequality. While a minority live in unprecedented wealth, the majority live in considerable poverty. Though much money has been given in aid by the rich countries to the poor, both by secular and Christian institutions, there has been much criticism that much of that aid has been wasted, indeed much of it has been actually harmful. But while there is truth in some of these criticisms, there is also increasing evidence of where community (...) development has been effective, and sustainable. This article considers the strengths and limitations, and examples, of such a church-based, bottom-up, approach to transforming the physical and spiritual needs of the individuals and their communities. We will see that it is, arguably, the only way that truly holistic transformation can be delivered, and consider some of the implications for Western Christians and Christian NGOs. (shrink)

There has, over the last few decades, been a considerable growth in the development ‘business’ where, largely western, donors have sought to help the poorer nations develop. Much of this growth has been driven by Christian motivation. Increasingly such projects are being held accountable to try to ensure that the money and the effort being spent are being well spent. The question that is being asked of, and by, development workers is ‘how do we know that we are making a (...) difference?’ and a range of practices have been developed to assess, to measure, to evaluate such effects. Terms like impact assessment, objectives, log-frames, objective verifiable indicators, baselines, clients, have become part of the language. In this paper the author raises various fundamental questions about this practice of evaluating development projects, and in so doing challenges the suitability of some of the current practices for development work.

See the external link on this entry for a "widget" supplied by Bloomsbury, which will give you access to the first chapter. -/- Today, we find ourselves surrounded by numerous reasons to despair, from loneliness, suffering and death at an individual level to societal alienation, oppression, sectarian conflict and war. No honest assessment of life can take place without facing up to these facts and it is not surprising that more and more people are beginning to suspect that the human (...) story will end in tragedy. However, this focus on despair does not paint a complete and accurate picture of reality, which is also inflected with beauty and goodness. Working with examples from poetry and literature, including Virginia Woolf and Jack Gilbert and the films of Terrence Malick, Melancholic Joy offers an honest assessment of the human condition. It unflinchingly acknowledges the everyday frustrations and extraordinary horrors that generate despair and argues that the appropriate response is to take up joy again, not in an attempt to ignore or dismiss evil, but rather as part of a “melancholic joy” that accepts the mystery of a world both beautiful and brutal.

We provide a new interpretation of Zeno’s Paradox of Measure that begins by giving a substantive account, drawn from Aristotle’s text, of the fact that points lack magnitude. The main elements of this account are (1) the Axiom of Archimedes which states that there are no infinitesimal magnitudes, and (2) the principle that all assignments of magnitude, or lack thereof, must be grounded in the magnitude of line segments, the primary objects to which the notion of linear magnitude applies. Armed (...) with this account, we are ineluctably driven to introduce a highly constructive notion of (outer) measure based exclusively on the total magnitude of potentially infinite collections of line segments. The Paradox of Measure then consists in the proof that every finite or potentially infinite collection of points lacks magnitude with respect to this notion of measure. We observe that the Paradox of Measure, thus understood, troubled analysts into the 1880’s, despite their knowledge that the linear continuum is uncountable. The Paradox was ultimately resolved by Borel in his thesis of 1893, as a corollary to his celebrated result that every countable open cover of a closed line segment has a finite sub-cover, a result he later called the “First Fundamental Theorem of Measure Theory.” This achievement of Borel has not been sufficiently appreciated. We conclude with a metamathematical analysis of the resolution of the paradox made possible by recent results in reverse mathematics. (shrink)

C.S. Peirce begins his 1903 lectures on pragmatism from the premise that the starting point for pragmatic philosophy as he envisions it must not be a concept of Being but rather of Feeling. Pragmatism, he explains, will be ‘an extreme realism’. Its first category will be ‘immediate consciousness’ conceived as a ‘pure presentness’ whose self-appearing is elemental to experience. Firstness cannot be couched in terms of recognition, cannot be contained in any first-person accounting of experience, and most of all can (...) in no way be construed as being ‘in the mind’ of a subject, however the subject is conceived. This article follows some of the byways of Peirce’s thinking on this constitutive field of experience prior to subject/object determinations, making links to James’s ‘pure experience’, Whitehead’s ‘critique of pure feeling’, and Deleuze/guattari’s ‘being of sensation’.

Do adolescents have the decisional capacity of adults? Or, are they in crucial ways still immature, that is, are they deficient decisionmakers? This questi.

Adolescents present a puzzle. There are foundational unclarities about how they should be regarded as decision-makers. Although superficially adolescents may appear to have mature decisional capacity, their decision-making is in many ways unlike that of adults. Despite this seemingly obvious fact, a concern for the claims of autonomy has led to the development of the legal doctrine of the mature minor. This legal construct considers adolescents, as far as possible, as equivalent to adults for the purpose of medical decision-making. The (...) movement to support independent decision-making by adolescents through providing information to them and securing their consent apart from their parents is encouraged by those legal understandings that hold that unemancipated minors should generally be considered as possessing effective decisional capacity. Such legal structures, however, do not adequately take account of the wide variations in adolescent capacities, the immaturity of most adolescent decision-makers, or the important contributions made by parents to the development of their adolescents through parental partnering in the adolescent’s decision-making. The data available indicate that in general adolescents should be regarded as apprentice decision-makers who should make decisions in collaboration with their parents until at least the age of 18. Steps should not be taken pre-emptively to isolate adolescents from the guidance of their parents. As a general rule, what Piker has referred to as “collaborative paternalism” appears most likely both to protect adolescents from their own untoward choices, while also very importantly helping them with parental guidance to develop into mature decision-makers with the capacity to make medical choices on their own.

Should we understand our lives as stories? Narrativism answers Yes, a view that has recently been the subject of vigorous debate. But what should Christian philosophers make of narrativism? In this essay, I argue that, in fact, narrativism is a commitment of Christian teaching. I argue that there are practices which Christians have decisive reasons to engage in, which require us to see our lives as narratives, practices such as confession and thanksgiving.

Clarke and Beck propose that the approximate number system (ANS) represents rational numbers. The evidence cited supports only the view that it represents ratios (and positive integers). Rational numbers are extensive magnitudes (i.e., sizes), whereas ratios are intensities. It is also argued that WHAT a system represents and HOW it does so are not as independent of one another as the authors assume.
