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.

Aristophanes’ Frogs was first performed at the Lenaea festival of 405 in competition with Plato's Cleophon and Phrynichus’ Muses. This paper argues that Frogs contains a series of agonistic jokes against Phrynichus, most of which have gone unnoticed because he shares his name with a tragic poet and a politician; Aristophanes plays with the ambiguity of the name Phrynichus to mock his Lenaean rival by comparing him unfavourably with his namesakes. Aristophanes ultimately claims that his comedy is superior to that (...) of Phrynichus because he is more successful than his rival in appropriating and redeploying other comedians’ material.

The own-age bias (OAB) refers to recognition memory being more accurate for people of our own-age than other-age groups (e.g., Wright and Stroud, 2002). This paper investigated whether the OAB effect is present during construction of human faces (also known as facial composites, often for forensic/police use). In doing so, it adds to our understanding of factors influencing both facial memory across the life span as well as performance of facial composites. Participant-witnesses were grouped into younger(19-35) and older(51-80) adults, and (...) each constructed a single composite from memory of an own- or cross-age target face using the feature-based composite system PRO-fit. They also completed the 40-item Glasgow Face Matching Test (GFMT; Burton, White and McNeill, 2010). A separate group of participants who were familiar with the relevant identities attempted to name the resulting composites. Correct naming of the composites revealed the presence of an OAB for older adults, who constructed more-identifiable composites of own-age than cross-age faces. For younger adults, age of target face did not influence correct naming and their composites we named at the same level as those constructed by older adults for younger targets. Also, there was no reliable correlation between face perception ability and composite construction. (shrink)

The essays in this collection treat historical, literary, and philosophical topics related to Ayn Rand's Anthem, an anti-utopia fantasy set in the future. The first book-length study on Anthem, this collection covers subjects such as free will, political freedom, and the connection between freedom and individual thought and privacy.

David Lewis has argued that “having an experience is the best way or perhaps the only way, of coming to know what that experience is like”; when an experience is of a sufficiently new sort, mere science lessons are not enough. Developing this Lewisian line, L.A. Paul has suggested that some experiences are epistemically transformative. Until an individual has such an experience it remains epistemically inaccessible to her. No amount of stories and theories and testimony from others can teach (...) her what it is like to have it, nor is she able to achieve this knowledge by way of imaginative projection. It’s this last claim that is the focus of this paper. In particular, I explore the case for the claim that some experiences are in principle imaginatively inaccessible to someone who has not undergone the experience itself or one relevantly similar. As I will suggest, this case is not as strong as is often thought. Close attention to the mechanisms of imagination, and in particular, to cases of skilled imaginers, suggests how techniques of imaginative scaffolding can sometimes be used to give us epistemic access to experiences we have not had, even ones that are radically different from any that we have had before. As a result, considerably fewer experiences remain imaginatively out of reach than proponents of transformative experience would have us believe. Experience may well be the best teacher, but this paper aims to show that imagination comes in a close second. (shrink)

What if Immanuel Kant floated down from his transcendental heights, straight through Alice’s rabbit hole, and into the fabulous world of Lewis Carroll? For Ben-Ami Scharfstein this is a wonderfully instructive scenario and the perfect way to begin this wide-ranging collection of decades of startlingly synthesized thought. Combining a deep knowledge of psychology, cultural anthropology, art history, and the history of religions—not to mention philosophy—he demonstrates again and again the unpredictability of writing and thought and how they can teach (...) us about our experiences. Scharfstein begins with essays on the nature of philosophy itself, moving from an autobiographical account of the trials of being a comparativist to philosophy’s function in the outside world to the fear of death in Kant and Hume. From there he explores an impressive array of art: from China and Japan to India and the West; from an essay on sadistic and masochistic body art to one on the epistemology of the deaf and the blind. He then returns to philosophy, writing on Machiavelli and political ruthlessness, then on the ineffable, and closes with a review of Walter Kaufmann’s multivolume look at the essence of humanity, _Discovering the Mind_. Altogether, these essays are a testament to adventurous thought, the kind that leaps to the furthest reaches of the possible. (shrink)

In this introduction to a special section on the philosophy of Bat-Ami Bar On, guest editor Court Lewis introduces Jennifer Kling’s article on equitable resettlement of refugees, Wim Laven’s article on meaningful political citizenship, and his own work on the analysis of the violent threat of citizen culture-warriors.

In tribute to the philosophy of Bat-Ami Bar On, this article draws upon her Arendtian analysis of fascism to explore recent dynamics of ethnic nationalism in the US. Whereas Bar On analyzed the problem of citizen-soldiers, this study extends analysis toward the citizen culture-soldier, suggesting that recent dynamics in the US are suggestive of a Cultural Revolution that threatens the inclusive practice of citizenship required of democracy. Bar On’s work motivates philosophers to not be lulled into acceptance of anti-democratic practices (...) of citizenship. The values of respect, equality, and equity suggest that another form of citizenship should be practically pursued. (shrink)

The essay discusses the March 5, 1944 "Discussion on Sin," an event that was held between French intellectual Georges Bataille and the Jesuit priest and patristics scholar Jean Daniélou, along with other important Christian and non-Christian intellectuals. I argue that the event is the best recorded wartime intellectual encounter between the founders of contestation (subsequently so important in deconstructive thought) and serious practitioners of Christianity. Aspects of the thought of French thinker Maurice Blanchot and Swiss theologian Hans Urs Von Balthasar (...) are also profiled. (shrink)

We often talk of people as being more or less imaginative than one another – as being better or worse at imagining – and we also compare various feats of imagination to one another in terms of how easy or hard they are. Facts such as these might be taken to suggest that imagination is often implicitly understood as a skill. This implicit understanding, however, has rarely (if ever) been made explicit in the philosophical literature. Such is the task of (...) this chapter. I first attempt to flesh out several conditions for an activity to count as a skill. I then attempt to show how imagination can meet such conditions. The chapter concludes with an attempt to answer various worries that might be raised to the claim that imagination should be thought of as a skill. (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.

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.

The intellectual history of the last quarter of this century has been marked by the growing influence of Africana thought--an area of philosophy that focuses on issues raised by the struggle over ideas in African cultures and their hybrid forms in Europe, the Americas, and the Caribbean. Existentia Africana is an engaging and highly readable introduction to the field of Africana philosophy and will help to define this rapidly growing field. Lewis R. Gordon clearly explains Africana existential thought to (...) a general audience, covering a wide range of both classic and contemporary thinkers--from Douglass and DuBois to Fanon, Davis and Zack.

The challenge of handling fictional discourse is to find the best way to resolve the apparent inconsistencies in our ways of speaking about fiction. A promising approach is to take at least some such discourse to involve pretense, but does all fictional discourse involve pretense? I will argue that a better, less revisionary, solution is to take internal and fictionalizing discourse to involve pretense, while allowing that in external critical discourse, fictional names are used seriously to refer to fictional characters. (...) I then address two objections to such realist theories of fiction: One, that they can’t adequately account for the truth of singular nonexistence claims involving fictional names, and two, that accepting that there are fictional characters to which we refer is implausible or ontologically profligate.

While post- and decolonial theorists have thoroughly debunked the idea of historical progress as a Eurocentric, imperialist, and neocolonialist fallacy, many of the most prominent contemporary thinkers associated with the Frankfurt School--Jürgen Habermas, Axel Honneth, and Rainer Forst--have persistently defended ideas of progress, development, and modernity and have even made such ideas central to their normative claims. Can the Frankfurt School's goal of radical social change survive this critique? And what would a decolonized critical theory look like? Amy Allen fractures (...) critical theory from within by dispensing with its progressive reading of history while retaining its notion of progress as a political imperative, so eloquently defended by Adorno. Critical theory, according to Allen, is the best resouce we have for achieving emancipatory social goals. In reimagining a decolonized critical theory after the end of progress, she rescues it from oblivion and gives it a future. (shrink)

Elegant, suggestive, and clarifying, Lewis Thomas's profoundly humane vision explores the world around us and examines the complex interdependence of all things. Extending beyond the usual limitations of biological science and into a vast and wondrous world of hidden relationships, this provocative book explores in personal, poetic essays to topics such as computers, germs, language, music, death, insects, and medicine. Lewis Thomas writes, "Once you have become permanently startled, as I am, by the realization that we are a (...) social species, you tend to keep an eye out for the pieces of evidence that this is, by and large, good for us.".

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.

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)

Bailey (2021) offers a clever argument for the compatibility of determinism and moral responsibility based on the nature of intrinsic intentions. The argument is mistaken on two counts. First, it is invalid. Second, even setting that first point aside, the argument proves too much: we would be blameworthy in paradigm cases of non-blameworthiness. I conclude that we cannot reason from intentions to responsibility solely from the “inside out”—our possessing a blameworthy intention cannot tell us whether this intention is also blameworthy (...) in deterministic worlds.

This paper is about the similarity between the appreciation of a piece of art, such as a cherished music album, and the loving appreciation of a person whom one knows well. In philosophical discussion about the rationality of love, the Qualities View (QV) says that love can be justified by reference to the qualities of the beloved. I argue that the oft-rehearsed trading-up objection fails to undermine the QV. The problems typically identified by the objection arise from the idea that (...) love-worthy qualities could be coarse-grained, when in fact they must be fine-grained. The analogy with appreciation of aesthetic qualities helps to draw out this point. Once the fine-grained nature of love-worthy qualities is properly understood, it is clear that critics of the QV cannot rely on the trading-up objection to motivate its rejection. Moreover, the paper’s core argument helps to illuminate the persistently aesthetic nature of interpersonal affections. (shrink)

In his note "can there be vague objects?" ("analysis", 1978), Gareth evans presents a purported proof that there can be no vague identity statements. Some readers think that evans endorses the proof and its false conclusion. Not so. His point is that those who put vagueness in the world, Rather than in language, Will have no way to fault the proof and no way to escape the false conclusion.

According to a recent paper by Tim Maudlin, Bell’s theorem has nothing to tell us about realism or the descriptive completeness of quantum mechanics. What it shows is that quantum mechanics is non-local, no more and no less. What I intend to do in this paper is to challenge Maudlin’s assertion about the import of Bell’s proof. There is much that I agree with in the paper; in particular, it does us the valuable service of demonstrating that Einstein’s objections to (...) quantum mechanics have nothing to do with its indeterminism. But I do think that Maudlin’s conclusion is overly cut-and-dried. Quantum mechanics is far from a unified edifice, and what Bell’s theorem shows depends on what version of quantum mechanics you look at. In particular, I’ll try to make the case that there’s an interesting, if ultimately uncompelling anti-realist construal of the import of Bell’s theorem. And I also want to suggest that locality isn’t quite as decisively defeated as Maudlin claims. (shrink)

While Roman Ingarden is well known for his work in aesthetics and studies in ontology, one of his most important and lasting contributions has been largely overlooked: his approach to a general ontology of social and cultural objects. Ingarden himself discusses cultural objects other than works of art directly in the first section of “The Architectural Work”1, where he develops a particularly penetrating view of the ontology of buildings, flags, and churches. This text provides the core insight into how his (...) more lengthy studies of the ontology of works of art in The Literary Work of Art and the rest of The Ontology of the Work of Art, combined with the ontological distinctions of Der Streit um die Existenz der Welt, may be used to understand social and cultural objects. The view that results, I will argue, is based in foreseeing problems with the reductivist and projectivist views that remain popular, and is capable of resolving central problems still thought to plague those who would offer a theory of cultural objects.

I offer a new interpretation of Heidegger’s analysis of anxiety in Being and Time as an account of the relationship between individual agents and the public normative practices of their communities. According to a prominent recent interpretation, Heidegger’s discussions of anxiety, death and the “call of conscience” together explain how we can respond to the norms of our practices as reasons and subject them to critical reflection. I argue that this is only part of the story. Anxiety is an occasion (...) for Dasein to take responsibility for its ongoing activity of interpreting the possibilities for living and acting made available by the normative practices of its community, which is presupposed and overlooked from the perspective of everyday Dasein. Public normativity underdetermines Dasein’s conception of what it would mean to take up any of the possibilities available in its world as a way of living its own life. (shrink)

Shows that many of our understandings about scientific thought can be corrected once we realise just how unnatural science is. Quoting scientists from Aristotle to Einstein, the book argues that scientific ideas are, with rare exceptions, counter-intuitive and contrary to common sense.

Empathy has for a long time, at least since the eighteenth century, been seen as centrally important in relation to our capacity to gain a grasp of the content of other people's minds, and predict and explain what they will think, feel, and do; and in relation to our capacity to respond to others ethically. In addition, empathy is seen as having a central role in aesthetics, in the understanding of our engagement with works of art and with fictional characters. (...) A fuller understanding of empathy is now offered by the interaction of research in science and the humanities. This volume draws together nineteen original chapters by leading researchers across several disciplines, together with an extensive Introduction by the editors. The individual chapters reveal how important it is, in a wide range of fields of enquiry, to bring to bear an understanding of the role of empathy in its various guises. It offers the ideal starting-point for the exploration of this intriguing aspect of human life. (shrink)

Imagination is celebrated as our vehicle for escape from the mundane here and now. It transports us to distant lands of magic and make-believe, and provides us with diversions during boring meetings or long bus rides. Yet the focus on imagination as a means of escape from the real world minimizes the fact that imagination seems also to furnish us with knowledge about it. Imagination seems an essential component in our endeavor to learn about the world in which we live--whether (...) we're planning for the future, aiming to understand other people, or figuring out whether two puzzle pieces fit together. But how can the same mental power that allows us to escape the world as it currently is also inform us about the world as it currently is? Ten original essays grapple with this neglected question; in doing so, they present a diverse array of positions ranging from cautious optimism to deep-seated pessimism. Blending perspectives from philosophy of mind, cognitive science, epistemology, aesthetics, and ethics, Knowledge Through Imagination sheds new light on the epistemic role of imagination. (shrink)

Opponents of abortion sometimes hold that it is impermissible because fetuses are persons from the moment of conception. But miscarriage, which ends up to 89 % of pregnancies, is much deadlier than abortion. That means that if opponents of abortion are right, then miscarriage is the biggest public-health crisis of our time. Yet they pay hardly any attention to miscarriage, especially very early miscarriage. Attempts to resolve this inconsistency by adverting to the distinction between killing and letting die or to (...) the difficulty of preventing miscarriage fail, leaving a dilemma. Opponents of abortion should either advocate a substantial shift in our political and medical priorities or else give up the view that fetuses are persons from the moment of conception. (shrink)

ABSTRACT A thriving project in contemporary epistemology concerns identifying and explicating the epistemic virtues. Although there is little sustained argument for this claim, a number of prominent sources suggest that curiosity is an epistemic virtue. In this paper, I provide an account of the virtue of curiosity. After arguing that virtuous curiosity must be appropriately discerning, timely and exacting, I then situate my account in relation to two broader questions for virtue responsibilists: What sort of motivations are required for epistemic (...) virtue? And do epistemic virtues need to be reliable? I will sketch an account on which curiosity is only virtuous when rooted in a non-instrumental appreciation of epistemic goods, before arguing that curiosity can exhibit intellectual virtue irrespective of whether one is reliable in satisfying it.
