According to the dogmatism puzzle, for any S and any p, if S knows that p, then she’s entitled to be dogmatic about p, and so disregard any evidence against p, for she knows that (or is in a position to know that) that evidence is misleading. But this seems clearly problematically dogmatic. The standard solution to the dogmatism puzzle involves appealing to the view that acquiring new evidence (even misleading evidence) can undermine one’s knowledge that p. That’s why one (...) can’t rightly disregard any future evidence against p. This solution to the dogmatism puzzle has come to be called ‘the defeat solution’. Maria Lasonen-Aarnio has recently argued, however, that the defeat solution leaves unsolved a partial defeat version of the dogmatism puzzle, where some subject acquires weak misleading evidence against p, but, since it is weak, it doesn’t rob her of knowledge that p. Lasonen-Aarnio argues that solving this partial defeat version of the dogmatism puzzle requires those who endorse the defeasibility of knowledge to either go dogmatist or reject an extremely plausible principle that she calls ‘Entitlement’ (roughly, for any S and any e, if S knows that evidence e is misleading, then S can rightly disregard e). In this paper, however, I argue that defeasibilists face no such challenge from any version of the dogmatism puzzle, since the dogmatism puzzle, in both its original and partial defeat form, rests on an assumption that we have very good reason to think is mistaken. Specifically, the assumption that, for any S and any p, if S knows that p, then S knows (or is in a position to know) that any evidence against p is misleading. I further argue that rejecting this assumption also yields a neat solution to the dogmatism puzzle involving intention originally proposed by Saul Kripke and recently adapted by R.E. Fraser.

Is there a world beyond the senses? Can we perceive future events before they occur? Is it possible to communicate with others without need of our complex sensory-perceptual apparatus that has evolved over hundreds of millions of years? Can our minds/souls/personalities leave our bodies and operate with all the knowledge and information-processing ability that is normally dependent upon the physical brain? Do our personalities survive physical death?

Abstract:Disturbing cases continue to be published of patients declared brain dead who later were found to have a few intact brain functions. We address the reasons for the mismatch between the whole-brain criterion and brain death tests, and suggest solutions. Many of the cases result from diagnostic errors in brain death determination. Others probably result from a tiny amount of residual blood flow to the brain despite intracranial circulatory arrest. Strategies to lessen the mismatch include improving brain death determination training (...) for physicians, mandating a test showing complete intracranial circulatory arrest, or revising the whole-brain criterion.

This paper defends an invariance-based account of laws of nature: Laws are generalizations that remain invariant under various sorts of changes. Alternatively, laws are generalizations that exhibit a certain kind of independence from background conditions.

Baggs and Chemero (2018)propose that certain tensions between enaction and ecological psychology arise due different interpretations about what is meant by the “environment.” In the enactive approach the emphasis is on the umwelt, which describes the environment as the “meaningful, lived surroundings of a given individual.” The ecological approach, on the other hand, emphasises what they refer to as the habitat “the environment as a set of resources for a typical, or ideal, member of a species.” By making this distinction, (...) these authors claim they are able to retain the best of both the ecological and the enactive approaches. Herein I propose an account of the individuation of habits that straddles this distinction, what I call a compatabilist account. This is done in two parts. The first part teases out a host of compatibilities that exist between the enactive account as developed byDi Paolo et al. (2017)and the skilled intentionality framework as developed byBruineberg and Rietveld (2014)andRietveld and Kiverstein (2014). In part two these compatibilities are brought together with the philosophy of Gilbert Simondon to develop the notion of enhabiting. Enhabiting describes a set of ongoing processes by which an umwelt emerges from and is reproduced within the relationship between an embodied subject and their habitat. Thus, enhabiting points toward a point of intersection between enaction and ecological psychology. To enhabit is bring forth (to enact), within (to inhabit). (shrink)

Research involving human subjects is much more stringently regulated than many other nonresearch activities that appear to be at least as risky. A number of prominent figures now argue that research is overregulated. We argue that the reasons typically offered to justify the present system of research regulation fail to show that research should be subject to more stringent regulation than other equally risky activities. However, there are three often overlooked reasons for thinking that research should be treated as a (...) special case. First, research typically involves the imposition of risk on people who do not benefit from this risk imposition. Second, research depends on public trust. Third, the complexity of the moral decision making required favors ethics committees as a regulative solution for research. (shrink)

In this paper, I review recent attempts by experimental philosophers and psychologists to study folk metaethics empirically and discuss some of the difficulties that researchers face when trying to construct the right kind of research materials and interpreting the results that they obtain. At first glance, the findings obtained so far do not look good for the thesis that people are everywhere moral realists about every moral issue. However, because of difficulties in interpreting these results, I argue that better research (...) is needed to move the debate forward. (shrink)

In a seminal 1977 article, Rumelhart argued that perception required the simultaneous use of multiple sources of information, allowing perceivers to optimally interpret sensory information at many levels of representation in real time as information arrives. Building on Rumelhart's arguments, we present the Interactive Activation hypothesis—the idea that the mechanism used in perception and comprehension to achieve these feats exploits an interactive activation process implemented through the bidirectional propagation of activation among simple processing units. We then examine the interactive activation (...) model of letter and word perception and the TRACE model of speech perception, as early attempts to explore this hypothesis, and review the experimental evidence relevant to their assumptions and predictions. We consider how well these models address the computational challenge posed by the problem of perception, and we consider how consistent they are with evidence from behavioral experiments. We examine empirical and theoretical controversies surrounding the idea of interactive processing, including a controversy that swirls around the relationship between interactive computation and optimal Bayesian inference. Some of the implementation details of early versions of interactive activation models caused deviation from optimality and from aspects of human performance data. More recent versions of these models, however, overcome these deficiencies. Among these is a model called the multinomial interactive activation model, which explicitly links interactive activation and Bayesian computations. We also review evidence from neurophysiological and neuroimaging studies supporting the view that interactive processing is a characteristic of the perceptual processing machinery in the brain. In sum, we argue that a computational analysis, as well as behavioral and neuroscience evidence, all support the Interactive Activation hypothesis. The evidence suggests that contemporary versions of models based on the idea of interactive activation continue to provide a basis for efforts to achieve a fuller understanding of the process of perception.

I present a new perspective on the meaning of indistinguishability of classical particles. This leads to a solution to the problem in statistical mechanics of justifying the inclusion of a factor N! in a probability distribution over the phase space of N indistinguishable classical particles.

Within the corporate social responsibility research field, the construct of organizational reputation has been extensively scrutinized as a crucial mediator between the firm CSR engagement and valuable organizational outcomes. Yet, the existing literature on organizational reputation suffers from substantive divergence between the studies in terms of defining the construct’s domain, dimensional structure, and the methodological operationalization. The current study aims to refine the organizational reputation construct by reconciling varying theoretical perspectives within the construct’s definitional landscape, suggesting a holistic but parsimonious (...) triadic view on the organizational reputation construct for customer stakeholders. Based on commonly used extant organizational reputation measures, we theoretically and empirically develop the customer-based triadic organizational reputation scale and position it as a superordinate multidimensional construct influencing three distinct first-order dimensions: product and service efficacy, societal ethicality, and market prominence. Results show that the proposed triadic conceptualization of organizational reputation is theoretically defensible, and the resulting scale is cross-culturally generalizable and performs well compared with existing, longer measures of organizational reputation. Together, the organizational reputation model developed here suggests that, for cognitive economy and functional efficiency, customers will access a second-order reflective model of organizational reputation as the default implicit attitude, which in turn will activate reflections of the implicit attitude in the form of first-order dimensions.

Individuals and businesses make numerous payments every day. They sometimes have choices about what forms of payment to make or accept, and at other times are effectively forced to use a particular form. Often there is an asymmetric power relationship between payer and payee that raises the issue of whether one side unfairly exploits the other. Is it unethical exploitation for an employer to pay employees with a fee-laden payroll card over other more convenient forms of payment? Does the fee (...) structure of payment networks such as Visa and MasterCard unfairly exploit merchants? The bitcoin payment system is an ethical as well as technological evolution as it was designed to be an electronic payment system that does not rely upon trust. Can an entire payment system like bitcoin be “evil,” as charged by Krugman? Payment tools as such are ethically neutral, but can be used in an ethical or unethical manner. (shrink)

Background The ethical governance of Artificial Intelligence (AI) in health care and public health continues to be an urgent issue for attention in policy, research, and practice. In this paper we report on central themes related to challenges and strategies for promoting ethics in research involving AI in global health, arising from the Global Forum on Bioethics in Research (GFBR), held in Cape Town, South Africa in November 2022. Methods The GFBR is an annual meeting organized by the World Health (...) Organization and supported by the Wellcome Trust, the US National Institutes of Health, the UK Medical Research Council (MRC) and the South African MRC. The forum aims to bring together ethicists, researchers, policymakers, research ethics committee members and other actors to engage with challenges and opportunities specifically related to research ethics. In 2022 the focus of the GFBR was “Ethics of AI in Global Health Research”. The forum consisted of 6 case study presentations, 16 governance presentations, and a series of small group and large group discussions. A total of 87 participants attended the forum from 31 countries around the world, representing disciplines of bioethics, AI, health policy, health professional practice, research funding, and bioinformatics. In this paper, we highlight central insights arising from GFBR 2022. Results We describe the significance of four thematic insights arising from the forum: (1) Appropriateness of building AI, (2) Transferability of AI systems, (3) Accountability for AI decision-making and outcomes, and (4) Individual consent. We then describe eight recommendations for governance leaders to enhance the ethical governance of AI in global health research, addressing issues such as AI impact assessments, environmental values, and fair partnerships. Conclusions The 2022 Global Forum on Bioethics in Research illustrated several innovations in ethical governance of AI for global health research, as well as several areas in need of urgent attention internationally. This summary is intended to inform international and domestic efforts to strengthen research ethics and support the evolution of governance leadership to meet the demands of AI in global health research.

Following Jacques Hadamard, applied mathematicians typically investigate their models in the form of well-set problems, which actually consist of a family of applicational circumstances that vary in specific ways with respect to their initial and boundary values. The chief motive for investigating models in this wider manner is to avoid the improper behavioral conclusions one might reach from the consideration of a more restricted range of cases. Suitable specifications of the required initial and boundary variability typically appeal to previously established (...) experimental conclusions as to how the target system will behave under a range of eternally applied manipulations of the form “If the conditions pertaining to S were altered in manner M, internal features X would/would not alter”. In his investigations of causal reasoning within other parts of science, our first author has emphasized the conceptual importance of counterfactuals of this nature, for which he was been often criticized by authors of a self-styled “metaphysical” inclination. The purpose of this note is to argue, pace these objections, that closely analogous considerations have long been part of the practice of investigating differential equation models in a sensible way.

Why worry about Wittgenstein’s Tractatus? Did not Wittgenstein himself come to think it was largely a mistaken work? Is not Wittgenstein’s important work his later work? And does not his later work consist in a rejection of his earlier views? So does not the interest of the Tractatus mostly lie in its capacity to furnish a particularly vivid exemplar of the sort of philosophy that the mature Wittgenstein was most concerned to reject? So is it not true that the only (...) real reason to worry about the Tractatus is to become clear about what sort of thing it was that the later Wittgenstein was most against in philosophy? Is the interest of the book therefore not largely exhausted by its capacity to show us what the later Wittgenstein did not think? Much of the secondary literature on Wittgenstein’s Tractatus, either implicitly or explicitly, answers these questions largely in the affirmative. The aim of this paper is to suggest that the manner in which it has done so has done much to obstruct the possibility of an understanding of Wittgenstein’s philosophy – both early and late. The aim is not to suggest that these questions should be answered instead in the negative, but rather to furnish a prolegomenon to the possibility of a proper understanding of what – and how much – ought to be affirmed in answering them in the affirmative. As the present volume makes evident, there is currently a debate underway about how to read (and how not to read) Wittgenstein’s Tractatus. This paper will not attempt a direct contribution to that debate,2 it will attempt instead to bring out some of what might be at stake in that debate. It is natural to think that all that ought to be at stake is a fairly parochial question concerning the proper interpretation of Wittgenstein’s work during a single, relatively early phase of his philosophical development. Thus it is natural to conclude that, whatever differences may divide the parties to this debate concerning how to read the Tractatus, nonetheless, au fond these interpreters of Wittgenstein may be in broad agreement about how to read most of the rest of Wittgenstein’s work – or, at least, whatever their disagreements may be about the early work, they are ones that can be independently adjudicated, without substantial cost to anyone’s prior....

Understanding Poststructuralism presents a lucid guide to some of the most exciting and controversial ideas in contemporary thought. This is the first introduction to poststructuralism through its major theorists - Derrida, Deleuze, Foucault, Lyotard, Kristeva - and their central texts. Each chapter takes the reader through a key text, providing detailed summaries of the main points of each and a critical and detailed analysis of their central arguments. Ideas are clearly explained in terms of their value to both critical thinking (...) and to contemporary issues. Criticisms of poststructuralism are also assessed. The aim throughout is to illuminate the main methods of poststructuralism - deconstruction, libidinal economics, genealogy and transcendental empiricism - in context. A balanced and up-to-date assessment of poststructuralism, the book presents the ideal introduction to this most revolutionary of philosophies. (shrink)

In the wake of Locke’s Essay, empiricists faced the challenge of giving an empiricist account of the origins of moral knowledge. Locke did not rise to this challenge and relied on revelation as the source of moral knowledge. Other empiricists, including Hume and Hutcheson, opted for either emotivism or subjectivism. Clarke and others opted for rationalism and non-naturalism. In contrast, Catharine Cockburn’s meta-ethics combined Locke’s empiricism with naturalism. She held that moral good is natural good and that natural good is (...) known just as any other matters of natural fact are known: empirically. Cockburn’s position was unusual for its time, and the full originality and appeal of her meta-ethical position have not been fully appreciated. (shrink)

This article criticises David Chalmers’ ‘Reality+’ by interrogating its distinction of virtual reality (VR) from 2D, non-VR video games, a distinction made on the grounds that VR is immersive and these types of video games are not because immersion is a distinct characteristic of 3D perceptually represented VR. Building on the Balcerak Jacksons’ account of ‘representational immersion’, which they acknowledge has ‘perceptual’ and ‘non-perceptual’ elements, I develop an account of ‘non-perceptual representational immersion’ and use it to critique Chalmers’ treatment of (...) VR, immersion, and video games, indirectly problematizing his central ontological claim that ‘virtual reality is genuine reality’ and the reflections he makes about future society which rest upon it. I argue that video games are rich in non-perceptual representational immersion, which includes the representation of non-perceptual information about the structure and behaviour of a virtual world and its systems, the non-perceptual cognitive states that are generated in the player by the virtual world, and the immersion which comes from the constitutively cognitive nature of the player’s engagement with the virtual world, a cognitive engagement construed in an enactive sense. These are just as crucial to the phenomenon of digital immersion as perception. Immersion generally is a much more complicated phenomenon than Chalmers allows for, and it is better conceived as taking place on a spectrum which includes both 3D and 2D experiences of virtual worlds, not as hinging on 3D perceptual representation. I use ‘immersive simulation’ games as a case study. (shrink)

Prior work has demonstrated that young children in the US and the Ecuadorian Amazon preferentially remember information about the dangerousness of an animal over both its name and its diet. Here we explore if this bias is present among older children and adults in Fiji through the use of an experimental learning task. We find that a content bias favoring the preferential retention of danger and toxicity information continues to operate in older children, but that the magnitude of the bias (...) diminishes with age and is absent in adults. We also find evidence that fitness costs likely impact the types of mistakes that participants make in their attributions of dangerousness and poisonousness. These results suggest that natural selection has shaped the way in which we learn and make inferences about unfamiliar animal species over ontogeny, and that future research is needed on how content biases may vary across the life course.

Notably absent from much of the psychological literature on emotion regulation are attempts to answer explicitly normative questions about the phenomenon. It is one thing to explain how emotional states are regulated. It is another thing to say something about what reasons there are to regulate our emotions, whether and why we might sometimes be obligated to regulate our emotions, and how we regulate our emotions well, or optimally. This paper is an attempt at the latter task, focused specifically on (...) a type of emotion regulation also receiving little attention in the literature—what I call dispositional emotion regulation. Dispositional regulation occurs, when it does, at some point or period of time significantly prior to the onset of affected emotional states or episodes, and by means of modifying the subject’s emotional dispositions. And it is done well, or optimally, I argue, when it is done with an aim toward achieving and maintaining a coherent and comprehensible self, in the sense Shaftesbury had in mind. (shrink)

SummaryThe effects of infant suckling patterns on the post-partum resumption of ovulation and on birth-spacing are investigated among the Gainj of highland New Guinea. Based on hormonal evidence, the median duration of lactational anovulation is 20·4 months, accounting for about 75% of the median interval between live birth and next successful conception. Throughout lactation, suckling episodes are short and frequent, the interval changing slowly over time, from 24 minutes in newborns to 80 minutes in 3-year olds. Maternal serum prolactin concentrations (...) decline in parallel with the changes in suckling patterns, approaching the level observed in non-nursing women by about 24 months post-partum. A path analysis indicates that the interval between suckling episodes is the principal determinant of maternal prolactin concentration, with time since parturition affecting prolactin secretion only in so far as it affects suckling frequency. The extremely prolonged contraceptive effect of breast-feeding in this population thus appears to be due to a slow decline in suckling frequency with time since parturition and absence of a decline over time in hypothalamic–pituitary responsiveness to the suckling stimulus.
