To address longstanding workforce shortages, increase efficiency and control the costs associated with the modern health-care provision, there has been a worldwide policy to promote increased flexibility within the health-care workforce. This is being done primarily by extending the ‘scope of practice’ of existing occupational roles into what is referred to as ‘advanced’ practice. The development of the advanced practice nurse (APN) has occurred within the context of a shortage of medical staff, and the need to control cost. However, the (...) means by which substantially repurposed occupational groups such as these, are incorporated into complex, hierarchical organisations such as the UK national health service (NHS) remains poorly understood. Using modern sociological theory, the development of the APN role has been examined in terms of power, control, professional identity and gender relations. Each of the theoretical approaches used adds to the quality of the discussion, although none provide a comprehensive picture. However, when synthesised, they do provide an enhanced insight into the evolution of the role. It is argued here that by critically examining the development of the APN role, this will enable both a better understanding of, and the means to influence, its future direction of travel. (shrink)

Neural substrates of fatigue in traumatic brain injury are not well understood despite the considerable burden of fatigue on return to productivity. Fatigue is associated with diminishing performance under conditions of high cognitive demand, sense of effort, or need for motivation, all of which are associated with cognitive control brain network integrity. We hypothesize that the pathophysiology of TBI results in damage to diffuse cognitive control networks, disrupting coordination of moment-to-moment monitoring, prediction, and regulation of behavior. We investigate the cingulo-opercular (...) and frontoparietal networks, which are engaged to sustain attention for task and maintain performance. A total of 61 individuals with mild TBI and 42 orthopedic control subjects participated in functional MRI during performance of a constant effort task requiring altering the amount of effort utilized to manually squeeze a pneumostatic bulb across six 30-s trials. Network-based statistics assessed within-network organization and fluctuation with task manipulations by group. Results demonstrate small group differences in network organization, but considerable group differences in the evolution of task-related modulation of connectivity. The mild TBI group demonstrated elevated CO connectivity throughout the task with little variation in effort level or time on task, while CO connectivity diminished over time in controls. Several interregional CO connections were predictive of fatigue in the TBI group. In contrast, FP connectivity fluctuated with task manipulations and predicted fatigue in the controls, but connectivity fluctuations were delayed in the mild traumatic brain injury group and did not relate to fatigue. Thus, the mTBI group’s hyper-connectivity of the CO irrespective of task demands, along with hypo-connectivity and delayed peak connectivity of the FP, may allow for attainment of task goals, but also contributes to fatigue. Findings are discussed in relation to performance monitoring of prediction error that relies on internal cues from sensorimotor feedback during task performance. Delay or inability to detect and respond to prediction errors in TBI, particularly evident in bilateral insula-temporal CO connectivity, corresponds to day-to-day fatigue and fatigue during task performance.

David Lewis is widely credited with the first formulation of common knowledge and the first rigorous analysis of convention. However, common knowledge and convention entered mainstream game theory only when they were formulated, later and independently, by other theorists. As a result, some of the most distinctive and valuable features of Lewis' game theory have been overlooked. We re-examine this theory by reconstructing key parts in a more formal way, extending it, and showing how it differs from more (...) recent game theory. In contrast to current theories of common knowledge, Lewis' theory is based on an explicit analysis of the modes of reasoning that are accessible to rational individuals and so can be used to analyse the genesis of common knowledge. Lewis' analysis of convention emphasises the role of inductive reasoning and of salience in the maintenance of conventions over time.

Mechanisms are the how of chemical reactions. Substances are individuated by their structures at the molecular scale, so a chemical reaction is just the transformation of reagent structures into product structures. Explaining a chemical reaction must therefore involve different hypotheses about how this might happen: proposing, investigating and sometimes eliminating different possible pathways from reagents to products. One distinctive aspect of mechanisms in chemistry is that they are broken down into a few basic kinds of step involving the breaking and (...) making of bonds between atoms. This is necessary for chemical kinetics, the study of how fast reactions happen, and what affects it. It draws on G.N. Lewis’ identification of the chemical bond as involving shared electrons, which from the 1920s achieved the commensuration of chemistry and physics. The breaking or making of a bond just is the transfer of electrons, so a chemical bond on one side of an equation might be balanced on the other side by the appearance of a corresponding quantity of excess charge. A bond is understood to have been exchanged for a pair of electrons. Since reaction mechanisms rely on identities, doesn’t the establishment of a reaction mechanism explain away the chemical phenomena, showing that they are no more than the movement of charges and masses? In one sense yes: these mechanisms seem to involve a conserved-quantity conception of causation. But in another sense no: the ‘lower-level’ entities can do what they do only when embedded in higher-level organisation or structure. There need be no threat of reduction. (shrink)

We present a new class of models of players’ reasoning in non-cooperative games, inspired by David Lewis's account of common knowledge. We argue that the models in this class formalize common knowledge of rationality in a way that is distinctive, in virtue of modelling steps of reasoning; and attractive, in virtue of being able to represent coherently common knowledge of any consistent standard of individual decision-theoretic rationality. We contrast our approach with that of Robert Aumann, arguing that the former (...) avoids and diagnoses certain paradoxes to which the latter may give rise when extended in particular ways. (shrink)

Carpendale & Lewis (C&L) rightly emphasise the central role of social interaction in the development of children's understanding of mind. Further support and justification for their theoretical focus are provided by research on advanced reasoning about socio-emotional and socio-motivational processes. Variability in social experience can explain both developmental change and within-age-group differences in such social understanding.

In this article I sketch G. N. Lewis’s views on chemical bonding and Linus Pauling’s attempt to preserve Lewis’s insights within a quantum‐mechanical theory of the bond. I then set out two broad conceptions of the chemical bond, the structural and the energetic views, which differ on the extent in which they preserve anything like the classical chemical bond in the modern quantum‐mechanical understanding of molecular structure. †To contact the author, please write to: Department of Philosophy, Durham University, (...) 50 Old Elvet, Durham DH1 3HN, UK; e‐mail: [email protected].

One of the most widely accepted explanations for the peculiarity of the modern European is his addiction to the ideal of romantic love. Its invention is supposed to have so radically transformed ethics, imagination and daily life, that we can hardly imagine the mental world of the ancients or the Orient where such an ideal of love is unknown. In the classic source for this view, The Allegory of Love , C. S. Lewis traces the modern ideal back to (...) medieval tales of courtly love. But he sees the devotion to romantic love as a distinguishing mark of the modern individualistic consciousness, which began, he says, with a new interest in ‘the inner workings of the human heart’.

Abstract Some fictions, it seems, represent the future as closed, in the sense that some future-tensed propositions are true in those fictions. Yet it is surprisingly difficult to accommodate this plausible thesis within an account of truth in fiction. A number of putative examples of closed fictional futures are discussed (Macbeth, Oedipus, Time and the Conways, The Time Machine) and the problems encountered in reconciling them with various accounts of truth in fiction (David Lewis', Gregory Currie's, Alex Byrne's) elaborated. (...) Connections are drawn between metaphysical views on time and theories of fiction, and an attempt is made to show how the tenseless theory of time (roughly, the denial that time flows) can illuminate accounts of fictional truth, and in particular the issue of how there can be true beliefs about what will happen in a fiction.

This essay examines three works by three women writers whose strategies for rewriting the past include a revisionary engagement with the cultural legacies of Ancient Greece and Rome: The Emperor’s Babe: A Novel, Looking for Livingstone: An Odyssey of Silence, and Voyage of the Sable Venus. It argues that each embodies a mode of resistance that both protests the historic oppression of women of colour and asserts a black female agency, insisting on an empowered present and future. In achieving this, (...) all three transgress or subvert conventional generic distinctions between verse and prose, and, in Lewis’s case, between the cultural forms and academic disciplines of art, art history and literature. Each work insists on a transnational conception of black identity, implicitly tracing black diasporic experience through Africa, Europe and the Americas, and asserting the continued interconnections between these three. And, in their confrontations with the histories of colonialism, empire and slavery, each invokes not just the history of the seventeenth to twenty-first centuries ce but also the cultures of Ancient Greece and Rome, the legacies of which underpinned these modern European processes of domination. Of the three works discussed here, those by Evaristo and Lewis ultimately constitute works of greater subversive power than does that of Philip. (shrink)

Robin McKenna argues that we need to make space for an approach to epistemology that avoids the idealizations typical of the field. He applies this approach to topics in applied and social epistemology, such as what to do about science denial, whether we should try to be intellectually autonomous, and what our obligations are to other inquirers.

Many of us hold false beliefs about matters that are relevant to public policy such as climate change and the safety of vaccines. What can be done to rectify this situation? This question can be read in two ways. According to the descriptive reading, it concerns which methods will be effective in persuading people that their beliefs are false. According to the normative reading, it concerns which methods we are permitted to use in the service of persuading people. Some effective (...) methods—a programme of brainwashing, say—would not be permissible. In this paper I compare “methods of rational persuasion” with what you might call “marketing methods” such as how one frames the problem of climate change. My aim is to show that “marketing methods” are preferable to “methods of rational persuasion”. My argument has two parts. First, I argue that the evidence suggests that “marketing methods” are more effective in persuading people to change their minds. Second, I argue that “marketing methods” are an acceptable response to the normative question. (shrink)

This volume is devoted to Lewis's work in metaphysics and epistemology. Topics covered include properties, ontology, possibility, truthmaking, probability, the mind-body problem, vision, belief, and knowledge. The purpose of this collection, and the volumes that precede and follow it, is to disseminate more widely the work of an eminent and influential contemporary philosopher. The volume will serve as a useful work of reference for teachers and students of philosophy.

This work defends an interrelated set of theses in value-theory, normative ethics and meta-ethics. The three Parts correspond to these three areas. Part One (Value) defends a biocentric theory of moral standing, and then the coherence and objectivity of belief in intrinsic value, despite recent objections. Intrinsic value is located in the flourishing of living creatures; specifically, a neo-Aristotelian, species-relative account is supplied of wellbeing or flourishing, in terms of the development of the essential capacities of one's species. There follows (...) a theory of priorities, or of relative intrinsic value, in which the satisfaction of basic needs takes priority over other needs and over wants, and the interests of complex and sophisticated creatures over those of others, where they are at stake. Part Two defends a practice-consequentialist theory of the criteria of rightness and of obligation, which leaves room for supererogation, underpins our intuitions about justice, commends population growth only where it is genuinely desirable, and responds better than act-consequentialism to objections like that concerned with the separateness of persons. Part Three sifts meta-ethical theories, rejects moral relativism, and defends a cognitivist and naturalist meta-ethic. In defending analytical naturalism, it takes into account the latest literature on supervenience. By responding to recent discussions, this study supersedes my _Theory of Value and Obligation_ (1987). It is equipped with detailed end-notes and an ample bibliography, which could prove a research tool of itself. (shrink)

Science is not a great way to make money, or these days, even a job. But there are great riches in it, and in this book too. Tim Bradford, 'New Scientist'.

In this paper, we defend two main claims. The first is a moderate claim: we have a negative duty to not use binary gender-specific pronouns he or she to refer to genderqueer individuals. We defend this with an argument by analogy. It was gravely wrong for Mark Latham to refer to Catherine McGregor, a transgender woman, using the pronoun he; we argue that such cases of misgendering are morally analogous to referring to Angel Haze, who identifies as genderqueer, as he (...) or she. The second is a radical claim: we have a negative duty to not use any gender-specific pronouns to refer to anyone, regardless of their gender identity. We offer three arguments in favor of this claim (which appeal to concerns about inegalitarianism and risk, invasions of privacy, and reinforcing essentialist ideologies). We also show why the radical claim is compatible with the moderate claim. Before concluding, we examine common concerns about incorporating either they or a neologism such as ze as a third-person singular gender-neutral pronoun. These concerns, we argue, do not provide sufficient reason to reject either the moderate or radical claim. (shrink)

This book is a defense of modal realism; the thesis that our world is but one of a plurality of worlds, and that the individuals that inhabit our world are only a few out of all the inhabitants of all the worlds. Lewis argues that the philosophical utility of modal realism is a good reason for believing that it is true.

We live in a world saturated in both racial and gendered divisions. Our focus is on one place where attitudes about these divisions diverge: language. We suspect most everyone would be horrified at the idea of adding race-specific pronouns, honorifics, generic terms, and so on to English. And yet gender-specific terms of the same sort are widely accepted and endorsed. We think this asymmetry cannot withstand scrutiny. We provide three considerations against incorporating additional race-specific terms into English, and argue that (...) these considerations also support eliminating the analogous gender-specific terms. With respect to these parts of speech, English should be no more gender-specific than it already is race-specific. (shrink)

In this paper I develop a version of contextualism that I call interests contextualism. Interests contextualism is the view that the truth-conditions of knowledge ascribing and denying sentences are partly determined by the ascriber’s interests and purposes. It therefore stands in opposition to the usual view on which the truth-conditions are partly determined by the ascriber’s conversational context. I give an argument against one particular implementation of the usual view, differentiate interests contextualism from other prominent versions of contextualism and argue (...) that, unlike those versions, interests contextualism can mitigate against the epistemic descent objection put forward by Duncan Pritchard in his ‘Contextualism, Scepticism, and the Problem of Epistemic Descent’ (the objection is that, on the contextualist view, an ascriber of knowledge cannot, for some subject S and proposition p, properly ascribe knowledge that p to S if that ascriber has previously retracted an earlier ascription of knowledge that p to S).

Gender classifications often are controversial. These controversies typically focus on whether gender classifications align with facts about gender kind membership: Could someone really be nonbinary? Is Chris Mosier really a man? I think this is a bad approach. Consider the possibility of ontological oppression, which arises when social kinds operating in a context unjustly constrain the behaviors, concepts, or affect of certain groups. Gender kinds operating in dominant contexts, I argue, oppress trans and nonbinary persons in this way: they marginalize (...) trans men and women, and exclude nonbinary persons. As a result, facts about membership in dominant gender kinds should not settle gender classification practices. (shrink)

What’s important about ‘coming out’? Why do we wear business suits or Star Trek pins? Part of the answer, we think, has to do with what we call agential identity. Social metaphysics has given us tools for understanding what it is to be socially positioned as a member of a particular group and what it means to self-identify with a group. But there is little exploration of the general relationship between self-identity and social position. We take up this exploration, developing (...) an account of agential identity—the self-identities we make available to others. Agential identities are the bridge between what we take ourselves to be and what others take us to be. Understanding agential identity not only fills an important gap in the literature, but also helps us explain politically important phenomena concerning discrimination, malicious identities, passing, and code-switching. These phenomena, we argue, cannot be understood solely in terms of self-identity or social position. (shrink)

Alex Byrne’s article, “Are Women Adult Human Females?”, asks a question that Byrne treats as nearly rhetorical. Byrne’s answer is, ‘clearly, yes’. Moreover, Byrne claims, 'woman' is a biological category that does not admit of any interpretation as (also) a social category. It is important to respond to Byrne’s argument, but mostly because it is paradigmatic of a wider phenomenon. The slogan “women are adult human females” is a political slogan championed by anti-trans activists, appearing on billboards, pamphlets, and anti-trans (...) online forums. In this paper, I respond to Byrne’s argument, revealing significant problems with its background assumptions, content, and methodology. (shrink)

David Lewis (1941-2001) was Class of 1943 University Professor of Philosophy at Princeton University. His contributions spanned philosophical logic, philosophy of language, philosophy of mind, philosophy of science, metaphysics, and epistemology. In On the Plurality of Worlds, he defended his challenging metaphysical position, "modal realism." He was also the author of the books Convention, Counterfactuals, Parts of Classes, and several volumes of collected papers.

Atheism has had a strong presence on YouTube since its founding in the mid-2000s, which coincided with the rise of the new atheism movement, and lay atheists were quick to use the platform to spread new atheist ideas. Drawing from a sample of sixty-five atheist YouTube channels located and observed through online ethnographic methods, this article views YouTube videos as educational resources for atheists. It investigates different types of educational videos and ways of thinking about science, philosophy, and religion that (...) atheist content creators utilize and promote. The analysis reveals that they consistently frame these domains of knowledge through the truth claims they make and generally construct them within a hierarchical framework, with scientific knowledge at the top and religious knowledge at the bottom. Overall, their educational content reproduces new atheist discourses around these subjects, revealing the continuing influence of new atheism, two decades after its emergence. Furthermore, the popularity of videos that debunk arguments from religious apologists suggests that the intended audience of these videos includes both atheists, who are expected to need to learn to defend their atheism in debate with religious others, and “potential atheists”, religious believers who can be deconverted using rational arguments.

In the 4th edition of this best-selling textbook, the authors introduce students to the business of philosophizing, thereby inducting them into the art of reasoning and analyzing key concepts in education. This introductory text, continuously in print for more than thirty years, is a classic in its field. It shows, first and foremost, the importance of philosophy in educational debate and as a background to any practical activity such as teaching. What is involved in the idea of educating a person (...) or the idea of educational success? What, if anything, can be known and how should we organize what we know for curriculum purposes? What are the criteria for establishing the optimum balance between formal and informal teaching techniques? How trustworthy is educational research? In addition to these questions, which strike to the heart of the rationale for the educative process as a whole, the authors explore such concepts as culture, creativity, autonomy, indoctrination, needs, interests and learning by discovery. In this new updated edition, the authors draw on the latest research in genetics to argue that education is uniquely human and is essentially what develops us as humans. Resisting modern tendencies to equate knowledge with opinion, and value judgments with taste, this book leads the reader into the business of philosophizing and champions the cause of reason in education.

A lineage of prominent philosophers who have discussed the second-person relation can be regarded as advancing structural accounts. They posit that the second-person relation effects one transformative change to the structure of practical reasoning. In this paper, I criticise this orthodoxy and offer an alternative, substantive account. That is, I argue that entering into second-personal relations with others does indeed affect one's practical reasoning, but it does this not by altering the structure of one's agential thought, but by changing what (...) reasons can become available. The importance of second-personal thought for action is heterogenous. Second-person relations make possible the emergence of a wide variety of different kinds of practical reasons: creating some, revealing others. Recognising this diminishes the appeal of the traditional, structural accounts of the practical significance of such second-personal relations. Moving away from structural accounts facilitates a more thorough understanding of the intersubjective form of action. (shrink)

What responsibility do individuals bear for structural injustice? Iris Marion Young has offered the most fully developed account to date, the Social Connections Model. She argues that we all bear responsibility because we each causally contribute to structural processes that produce injustice. My aim in this article is to motivate and defend an alternative account that improves on Young’s model by addressing five fundamental challenges faced by any such theory. The core idea of what I call the “Role-Ideal Model” is (...) that we are each responsible for structural injustice through and in virtue of our social roles, i.e. our roles as parents, colleagues, employers, citizens, etc., because roles are the site where structure meets agency. In short, the Role-Ideal Model explains how individual action contributes to structural change, justifies demands for action from each particular agent, specifies what kinds of acts should be undertaken, moderates between demanding too much and too little of individual agents, and provides an account of the critical responses appropriate for holding individuals accountable for structural injustice.
