Many people accept, at least implicitly, what I call the asymmetry claim: the view that moral realism is more defensible than aesthetic realism. This article challenges the asymmetry claim. I argue that it is surprisingly hard to find points of contrast between the two domains that could justify their very different treatment with respect to realism. I consider five potentially promising ways to do this, and I argue that all of them fail. If I am right, those who accept the (...) asymmetry claim have a significant burden of proof. (shrink)

There is a substantial literature on evolutionary debunking arguments (EDAs) in metaethics. According to these arguments, evolutionary explanations of our moral beliefs pose a significant problem for moral realism, specifically by committing the realist to an unattractive pessimism about the prospects of our having moral knowledge. In this paper, I argue that EDAs exploit an equivocation between two distinct readings of their central claim. One is plausibly true but has no epistemic relevance, and the other would have epistemic consequences for (...) realism, but is false. If I'm right, this undermines attempts to use evolutionary explanations to debunk belief in other domains too. (shrink)

It has become increasingly common for philosophers to make use of the concept of artistic value, and, further, to distinguish artistic value from aesthetic value. In a recent paper, ‘The Myth of (Non-Aesthetic) Artistic Value’, Dominic Lopes takes issue with this, presenting a kind of corrective to current philosophical practice regarding the use of the concept of artistic value. Here I am concerned to defend current practice against Lopes's attack. I argue that there is some unclarity as to what aspect (...) of this practice Lopes is objecting to, and I distinguish three kinds of objection that he could be read as making. I argue that none of these is adequately supported by Lopes's arguments, and that the corresponding three aspects of current philosophical practice are on firmer footing than Lopes's paper suggests. A new, plausible characterisation of artistic value will emerge from this discussion. (shrink)

It is common to distinguish between attributive and predicative goodness. There are good reasons to think that artistic value is a kind of attributive goodness. Surprisingly, however, much debate in philosophical aesthetics has proceeded as though artistic value is a kind of predicative goodness. As I shall argue, recognising that artistic value is attributive goodness has important consequences for a number of debates in aesthetics.

Can artworks be morally good or bad? Many philosophers have thought so. Does this moral goodness or badness bear on how good or bad a work isas art?This is very much a live debate.Autonomistsargue that moral value is not relevant to artistic value;interactionistsargue that it is. In this paper, I argue that the debate between interactionists and autonomists has been conducted unfairly: all parties to the debate have tacitly accepted a set of constraints which prejudices the issue against the interactionist. (...) I identify two demands which are routinely placed on arguments seeking to establish interaction and argue that they are, in fact, mutually conflicting.There are two upshots. First, in light of this, it is unsurprising that arguments for interaction have failed to meet with everybody’s satisfaction. The constraints are such that no argument can meet them. Second, recognizing this helps us uncover a new, promising, but hitherto overlooked strategy for establishing artistic-ethical interaction. (shrink)

The Acquaintance Principle has been the subject of extensive debate in philosophical aesthetics. In one of the most recent developments, it has become popular to claim that some works of conceptual art are counterexamples to it. It is further claimed that this is a genuinely new problem in the sense that it is a problem even for versions of the Acquaintance Principle modified to deal with previous objections. I argue that this is essentially correct; however, the claim as it stands (...) needs some work. I draw attention to, and defend, two assumptions on which the claim rests but which have so far gone unrecognized. I also address an objection that has recently been made to the claim and threatens to raise further complications for it. In doing this, we arrive at a fuller, more robust version of the initial claim. (shrink)

When a chimpanzee stockpiles rocks as weapons or when a frog sends out mating calls, we might easily assume these animals know their own motivations--that they use the same psychological mechanisms that we do. But as Beyond the Brain indicates, this is a dangerous assumption because animals have different evolutionary trajectories, ecological niches, and physical attributes. How do these differences influence animal thinking and behavior? Removing our human-centered spectacles, Louise Barrett investigates the mind and brain and offers an alternative (...) approach for understanding animal and human cognition. Drawing on examples from animal behavior, comparative psychology, robotics, artificial life, developmental psychology, and cognitive science, Barrett provides remarkable new insights into how animals and humans depend on their bodies and environment--not just their brains--to behave intelligently. Barrett begins with an overview of human cognitive adaptations and how these color our views of other species, brains, and minds. Considering when it is worth having a big brain--or indeed having a brain at all--she investigates exactly what brains are good at. Showing that the brain's evolutionary function guides action in the world, she looks at how physical structure contributes to cognitive processes, and she demonstrates how these processes employ materials and resources in specific environments. Arguing that thinking and behavior constitute a property of the whole organism, not just the brain, Beyond the Brain illustrates how the body, brain, and cognition are tied to the wider world.

The Halpern–Läuchli theorem, a combinatorial result about trees, admits an elegant proof due to Harrington using ideas from forcing. In an attempt to distill the combinatorial essence of this proof, we isolate various partition principles about products of perfect Polish spaces. These principles yield straightforward proofs of the Halpern–Läuchli theorem, and the same forcing from Harrington’s proof can force their consistency. We also show that these principles are not ZFC theorems by showing that they put lower bounds on the size (...) of the continuum. (shrink)

In ”Embodiment and Epistemology,” Louise Antony considers a kind of ”Cartesian epistemology” according to which, so far as knowing goes, knowers could be completely disembodied, that is, pure Cartesian egos. Antony examines a number of recent challenges to Cartesian epistemology, particularly challenges from feminist epistemology. She contends that we might have good reason to think that theorizing about knowledge can be influenced by features of our embodiment, even if we lack reason to suppose that knowing itself varies relative to (...) such features. She also argues that a masculinist bias can result in mishandling of cognitive differences in cases where they actually exist and she examines a number of the ways in which the maleness of philosophy has, according to feminists, distorted epistemology. Even if a Cartesian approach offers one indispensable part of a comprehensive epistemology, according to Antony, we still need an epistemology that answers questions raised by our everyday, embodied lives.

Stress in health care is affected by moral factors. When people are prevented from doing ‘good’ they may feel that they have not done what they ought to or that they have erred, thus giving rise to a troubled conscience. Empirical studies show that health care personnel sometimes refer to conscience when talking about being in ethically difficult everyday care situations. This study aimed to construct and validate the Stress of Conscience Questionnaire (SCQ), a nine-item instrument for assessing stressful situations (...) and the degree to which they trouble the conscience. The items were based on situations previously documented as causing negative stress for health care workers. Content and face validity were established by expert panels and pilot studies that selected relevant items and modified or excluded ambiguous ones. A convenience sample of 444 health care personnel indicated that the SCQ had acceptable validity and internal consistency (Cronbach’s alpha exceeded 0.83 for the overall scale). Explorative factor analysis identified and labelled two factors: ‘internal demands’ and ‘external demands and restrictions’. The findings suggest that the SCQ is a concise and practical instrument for use in various health care contexts. (shrink)

We have been discussing some of the fundamental features of the classical calculus of probability. The equiprobability of rival events was seen to be a major assumption of the calculus. Moreover, it is an assumption which the pure mathematician need not bother to justify. He need only present his formal system as follows.

In a 1955 lecture the physicist Richard Feynman reflected on the place of doubt within scientific practice. ‘Permit us to question, to doubt, to not be sure’, proposed Feynman, ‘it is possible to live and not to know’. In our contemporary world, the science of machine learning algorithms appears to transform the relations between science, knowledge and doubt, to make even the most doubtful event amenable to action. What might it mean to ‘leave room for doubt’ or ‘to live and (...) not to know’ in our contemporary culture, where the algorithm plays a major role in the calculability of doubts? I propose a posthuman mode of doubt that decentres the liberal humanist subject. In the science of machine learning algorithms the doubts of human and technological beings nonetheless dwell together, opening onto a future that is never fully reduced to the single output signal, to the optimised target.

Generic language (e.g., “tigers have stripes”) leads children to assume that the referenced category (e.g., tigers) is inductively informative and provides a causal explanation for the behavior of individual members. In two preregistered studies with 4- to 7-year-old children (N = 497), we considered the mechanisms underlying these effects by testing how correcting generics might affect the development of these beliefs about novel social and animal kinds (Study 1) and about gender (Study 2). Correcting generics by narrowing their scope to (...) a single individual limited beliefs that the referenced categories could explain what their members would be like while broadening the scope to a superordinate category (Study 2) uniquely limited endorsement of gender norms. Across both studies, correcting generics did not alter beliefs about feature heritability and had mixed effects on inductive inferences, suggesting that additional mechanisms (e.g., causal reasoning about shared features) contribute to the development of full-blown essentialist beliefs. These results help illuminate the mechanisms by which generics lead children to view categories as having rich inductive and causal potential; in particular, they suggest that children interpret generics as signals that speakers in their community view the referenced categories as meaningful kinds that support generalization. The findings also point the way to concrete suggestions for how adults can effectively correct problematic generics (e.g., gender stereotypes) that children may hear in daily life. (shrink)

Motivated by a characterization of weakly compact cardinals due to Todorcevic, we introduce a new cardinal characteristic, the C-sequence number, which can be seen as a measure of the compactness of a regular uncountable cardinal. We prove a number of ZFC and independence results about the C-sequence number and its relationship with large cardinals, stationary reflection, and square principles. We then introduce and study the more general C-sequence spectrum and uncover some tight connections between the C-sequence spectrum and the strong (...) coloring principle U(. . .), introduced in Part I of this series.

We investigate questions involving Aronszajn trees, square principles, and stationary reflection. We first consider two strengthenings of introduced by Brodsky and Rinot for the purpose of constructing κ‐Souslin trees. Answering a question of Rinot, we prove that the weaker of these strengthenings is compatible with stationary reflection at κ but the stronger is not. We then prove that, if μ is a singular cardinal, implies the existence of a special ‐tree with a cf(μ)‐ascent path, thus answering a question of Lücke.

The current studies (N = 255, children ages 4–5 and adults) explore patterns of age‐related continuity and change in conceptual representations of social role categories (e.g., “scientist”). In Study 1, young children's judgments of category membership were shaped by both category labels and category‐normative traits, and the two were dissociable, indicating that even young children's conceptual representations for some social categories have a “dual character.” In Study 2, when labels and traits were contrasted, adults and children based their category‐based induction (...) decisions on category‐normative traits rather than labels. Study 3 confirmed that children reason based on category‐normative traits because they view them as an obligatory part of category membership. In contrast, adults in this study viewed the category‐normative traits as informative on their own (not only as a cue to obligations). Implications for continuity and change in representations of social role categories will be discussed. (shrink)

This paper discusses the relationship between internationalisation, mobility, quality and equality in the context of recent developments in research policy in the European Research Area (ERA). Although these developments are specifically concerned with the growth of research capacity at European level, the issues raised have much broader relevance to those concerned with research policy and highly skilled mobility. The paper draws on a wealth of recent research examining the relationship between mobility and career progression with particular reference to a recently (...) completed empirical study of doctoral mobility in the social sciences (Ackers et al. Doctoral Mobility in the Social Sciences. Report to the NORFACE ERA-Network, 2007). The paper is structured as follows. The first section introduces recent policy developments including the European Charter for Researchers and Code of Conduct for the Recruitment of Researchers and the European Commission’s Green Paper on the ERA. The discussion focuses on concerns around the definition of ‘mobility’ and the tendency (in both policy circles and academic research) to conflate different forms of mobility and to equate these with notions of excellence or quality. Scientific mobility is shaped as much by ‘push’ factors (limited opportunity) as it is by the ‘draw’ of excellence. Scientists are exercising a degree of ‘choice’ within a specific and individualised framework of constraints. The following sections consider some of the ‘professional’ and ‘personal’ factors shaping scientific mobility and the influence that these have on the relationship between mobility, internationalisation and excellence. The paper concludes that mobility is not an outcome in its own right and must not be treated as such (as an implicit indicator of internationalisation). To do so contributes to differential opportunity in scientific labour markets reducing both efficiency and equality. (shrink)

In the past few years, scholars have been questioning whether the current approach in data ethics based on the higher level case studies and general principles is effective. In particular, some have been complaining that such an approach to ethics is difficult to be applied and to be taught in the context of data science. In response to these concerns, there have been discussions about how ethics should be “embedded” in the practice of data science, in the sense of showing (...) how ethical issues emerge in small technical choices made by data scientists in their day-to-day activities, and how such an approach can be used to teach data ethics. However, a precise description of how such proposals have to be theoretically conceived and could be operationalized has been lacking. In this article, we propose a full-fledged characterization of ‘embedding’ ethics, and how this can be applied especially to the problem of teaching data science ethics. Using the emerging model of ‘microethics’, we propose a way of teaching daily responsibility in digital activities that is connected to the higher level ethical challenges discussed in digital/data ethics. We ground this microethical approach into a virtue theory framework, by stressing that the goal of a microethics is to foster the cultivation of moral virtues. After delineating this approach of embedding ethics in theoretical detail, this article discusses a concrete example of how such a ‘micro-virtue ethics’ approach could be practically taught to data science students.

Viale introduced covering matrices in his proof that SCH follows from PFA. In the course of the proof and subsequent work with Sharon, he isolated two reflection principles, CP and S, which, under certain circumstances, are satisfied by all covering matrices of a certain shape. Using square sequences, we construct covering matrices for which CP and S fail. This leads naturally to an investigation of square principles intermediate between □κ and □ for a regular cardinal κ. We provide a detailed (...) picture of the implications between these square principles. (shrink)

Many children and adults experience significant breakdown in the use of language. The resulting pragmatic disorders present a considerable barrier to effective communication. This book is the first critical examination of the current state of our knowledge of pragmatic disorders and provides a comprehensive overview of the main concepts and theories in pragmatics. It examines the full range of pragmatic disorders that occur in children and adults and discusses how they are assessed and treated by clinicians. Louise Cummings attempts (...) to integrate the fields of pragmatics, language pathology and cognitive science by examining the ways in which pragmatics can make a useful contribution to debates about cognitive theories of autism. The reader is encouraged to think in a critical fashion about how clinicians, experimentalists and theorists deal with pragmatic issues. (shrink)

We continue our study of strongly unbounded colorings, this time focusing on subadditive maps. In Part I of this series, we showed that, for many pairs of infinite cardinals $\theta < \kappa $, the existence of a strongly unbounded coloring $c:[\kappa ]^2 \rightarrow \theta $ is a theorem of $\textsf{ZFC}$. Adding the requirement of subadditivity to a strongly unbounded coloring is a significant strengthening, though, and here we see that in many cases the existence of a subadditive strongly unbounded coloring (...) $c:[\kappa ]^2 \rightarrow \theta $ is independent of $\textsf{ZFC}$. We connect the existence of subadditive strongly unbounded colorings with a number of other infinitary combinatorial principles, including the narrow system property, the existence of $\kappa $ -Aronszajn trees with ascent paths, and square principles. In particular, we show that the existence of a closed, subadditive, strongly unbounded coloring $c:[\kappa ]^2 \rightarrow \theta $ is equivalent to a certain weak indexed square principle $\boxminus ^{\operatorname {\mathrm {ind}}}(\kappa, \theta )$. We conclude the paper with an application to the failure of the infinite productivity of $\kappa $ -stationarily layered posets, answering a question of Cox. (shrink)

[Anne:] “I can't, I'm in the depths of despair. Can you eat when you are in the depths of despair?”“I've never been in the depths of despair, so I can't say,” said Marilla.“Weren't you? Well did you ever try to imagine you were in the depths of despair?”” No, I didn't.”“Then I don't think you can understand what it's like. It's a very uncomfortable feeling indeed. When you try to eat a lump comes right up in your throat and you (...) can't swallow anything, not even if it was a chocolate caramel.”—L.M. Montgomery, Anne of Green Gables.Emotion, as a “suprarational” property, transcends rationality in that it can be thought of as a group, contextual rather than as a solely individual trait, and thus is a higher order property, as the above quote suggests. This proposal arises from a metatheoretical analysis of models available to broach questions of emotion. I use metatheoretical in the sense of both the context of theory production and the theory of theory. From the first arose the idea that emotion, through the use of irrationality, has surfaced as a working equivalent to inexplicability or rational relativity, and can be modelled more adequately as suprarational, with a unique nature in its own right. The latter led me to propose that the concept of emotion as contextual, a higher order group level property, is possible and tentatively profitable. (shrink)

Parallogic models the relationship between mind and context. It, as does the excerpt above, suggests that systems of logic are context specific and therefore parallel. This model points out that perceived departures in mental process, reasoning, may be more apparent than real. It also suggests a new way to conceive of mental illness by separating breakdowns in mental process from shifts in mental process.

When attempting to answer the question, in the context of clinical healthcare, one might be tempted to leap to either of two rather obvious, but seemingly contradictory conclusions. On the one hand, we might have a general impression of religion not making much of a distinctive and clear difference, at least in the actions and outcomes of most cases of clinical interaction. Those of us in the bioethics world of discourse are likely to think only of the less common cases (...) of Christian Scientists, Jehovah's Witnesses, Orthodox Jews, or certain religious groups who seem to the majority of the population to hold especially sectarian, if not beliefs about medical matters. The so-called mainstream religious groups do not get much attention because they largely don't cause much trouble ; they have learned to bracket their religious commitments from at least any professional settings ; or they don't hold views entailing consequences any different from those of most nonbelieving, generally upright individuals. Furthermore, although religious believers may have some distinctive views, these views don't often noticeably manifest themselves in distinctive or significant ways. (shrink)

How do people gather samples of evidence to learn about the world? Adults often prefer to sample evidence from diverse sources—for example, choosing to test a robin and a turkey to find out if something is true of birds in general. Children below age 9, however, often do not consider sample diversity, instead treating non‐diverse samples (e.g., two robins) and diverse samples as equivalently informative. The current study (N = 247) found that this discontinuity stems from developmental changes in standards (...) for evaluating evidence—younger children chose to learn from samples that best approximate idealized views of what category members are supposed to be like (e.g., the fastest cheetahs), with a gradual shift across age toward samples that cover more within‐category variation (e.g., cheetahs of varying speeds). These findings have implications for the relation between conceptual structure and inductive reasoning, and for the mechanisms underlying inductive reasoning more generally. (shrink)

The first truly multidisciplinary text of its kind, this book offers an original analysis of the current state of linguistic pragmatics. Cummings argues that no study of pragmatics can reasonably neglect the historical and contemporary influences on this.

Following the publication of her 2017 book, Unthought: The Power of the Cognitive Nonconscious, N. Katherine Hayles discusses the themes of the book with Louise Amoore and Volha Piotukh. From the development of a theory of nonconscious cognition, to the capacities of novels to enact the connections between disparate phenomena, Hayles reflects on what is at stake ethically in new human-technical assemblages.

As embodied theories of cognition are increasingly formalized and tested, care must be taken to make informed assumptions regarding the nature of concepts and representations. In this study, we outline three reasons why one cannot, in effect, represent the same concept twice. First, online perception affects offline representation: Current representational content depends on how ongoing demands direct attention to modality-specific systems. Second, language is a fundamental facilitator of offline representation: Bootstrapping and shortcuts within the computationally cheaper linguistic system continuously modify (...) representational content. Third, time itself is a source of representational change: As the content of underlying concepts shifts with the accumulation of direct and vicarious experience, so too does the content of representations that draw upon these concepts. We discuss the ramifications of these principles for research into both human and synthetic cognitive systems. (shrink)

In our contemporary moment, when machine learning algorithms are reshaping many aspects of society, the work of N. Katherine Hayles stands as a powerful corpus for understanding what is at stake in a new regime of computation. A renowned literary theorist whose work bridges the humanities and sciences among her many works, Hayles has detailed ways to think about embodiment in an age of virtuality, how code as performative practice is located, and the reciprocal relations among human bodies and technics. (...) This special issue follows the 2017 publication of her book Unthought: The Power of the Cognitive Nonconscious, in which Hayles traces the nonconscious cognition of biological life-forms and computational media. The articles in the special issue respond in different ways to Hayles’ oeuvre, mapping the specific contours of computational regimes and developing some of the ‘inflection points’ she advocates in the deep engagement with technical systems.

Shaun Gallagher applies enactivist thinking to a staggeringly wide range of topics in philosophy of mind and cognitive science, even venturing into the realms of biological anthropology. One prominent point Gallagher makes that the holistic approach of enactivism makes it less amenable to scientific investigation than the cognitivist framework it seeks to replace, and should be seen as a “philosophy of nature” rather than a scientific research program. Gallagher also gives truth to the saying that “if you want new ideas, (...) read old books”, showing how the insights of the American pragmatists, particularly Dewey and Mead, offer a variety of resources and tools that can be brought to bear on modern day enactivism. Here, I suggest that the adoption of enactivist thinking would undermine the assumptions of certain scientific positions, requiring their abandonment, rather than simply making it more difficult to conduct research within an enactivist framework. I then discuss how Mead’s work has been used previously as a “pragmatist intervention” to help resolve problems in a related 4E endeavour, Gibson’s ecological psychology, and make a case for the inclusion of radical behaviorism as another pragmatist resource for 4E cognition. I conclude with a plea for further enactivist intervention in studies of comparative cognition. (shrink)

The nature of moral judgments, and, more specifically, the question of how they relate, on the one hand, to objective reality and, on the other, to subjective experience, are issues that have been central to metaethics from its very beginnings. While these complex and challenging issues have been debated by analytic philosophers for over a century, it is only relatively recently that more interdisciplinary and empirically-oriented approaches to such issues have begun to see light. The present chapter aims to make (...) a contribution of that kind. We will present the results of an empirical – specifically, corpus linguistic – study that offers evidence that moral predicates exhibit hallmarks of subjectivity at the linguistic level, but also, that they differ significantly from paradigmatically subjective predicates.

Complaining about humanitarian refugees is rarely an unequivocal activity for society members. Their talk appears dilemmatic: ‘sympathy talk’, comprising rhetorical displays of ‘care’, tolerance and aesthetic evaluations, is woven together with more pejorative messages. In this article we investigate how ‘sympathy talk’ functions as a discursive resource in talk-in-interaction when people give accounts of minority group individuals. A ‘synthetic’ discursive psychological approach was employed to analyse a corpus of 12 talkback radio calls to an evening ‘shock jock’ radio personality in (...) Adelaide, Australia, after the stabbing death of a Sudanese-Australian refugee. Analysis shows how host and callers dialogically negotiate and orientate to various sympathetic and humanitarian descriptions/evaluations. We contend that sympathetic talk advances the activity of conversation, softening complaints that could be made accountable as prejudiced. Sympathy talk also functions as a counter-argument to perceived punitive or ‘racist’ complaints. Moreover, this article proposes that such rhetoric shares an ideological thread that potentially undermines Sudanese refugees’ social positioning. Dialogue that deploys sympathetic formulations may be an element in the increasingly varied and subtle activity of ‘new racism’. We discuss how sympathetic accounts contain, within their semantic structure, their own antithesis for their deployment in anti-racist practice; for the development of counter discourses fundamental to the disruption of pervasive ideological representations and the construction of alternative refugee identities.

Using multisource data and multilevel analysis, we propose that the ethical stance of supervisors influences subordinates’ perceptions of corporate social responsibility which in turn influences subordinates’ trust in the organization resulting in their taking increased personal social responsibility and engagement in organizational citizenship behaviors oriented toward both the organization and other individuals. Using a multilevel model, we assessed the extent to which ethical leadership and CSR at the work unit level impacts subordinates’ behaviors mediated by organizational trust at the individual (...) level. We employed a sample of 71 work unit supervisors and 308 subordinates from five businesses of a conglomerate company located in mainland China. Subordinates were asked to rate supervisory ethical leadership practices, CSR, and their extent of organizational trust. Supervisors were asked to rate the personal social responsibility taking and OCB of their respective subordinates. A multilevel path analysis revealed that ethical leadership has a positive effect on CSR at the work unit level and that CSR has a positive cross-level effect on organizational trust at the individual level, which in turn significantly and positively impacts OCB through the mediating effect of taking personal social responsibility. Results are discussed in the context of China’s manufacturing sector. (shrink)

In this paper I argue that there can be genuine (as opposed to merely verbal) disputes about whether a sentence form is logically true or an argument form is valid. I call such disputes ?cases of deviance?, of which I distinguish a weak and a strong form. Weak deviance holds if one disputant is right and the other wrong, but the available evidence is insufficient to determine which is which. Strong deviance holds if there is no fact of the matter. (...) In section 2 I argue that weak deviance need not be trivial and may even be interesting. Section 3 considers what it could mean to say that logic is determined by a theory, especially a theory of meaning, an idea that arises in section 2. In section 4 I discuss the dispute between classical and relevance logicians over entailment and argue that it is a case of strong deviance. Finally, in section 5 I show that the result of the previous section is not absolute but relative to the background logic used in reaching it. (shrink)
