We take up the challenge of developing an international network with capacity to survey the world's scientists on an ongoing basis, providing rich datasets regarding the opinions of scientists and scientific sub-communities, both at a time and also over time. The novel methodology employed sees local coordinators, at each institution in the network, sending survey invitation emails internally to scientists at their home institution. The emails link to a ‘10 second survey’, where the participant is presented with a single statement (...) to consider, and a standard five point Likert scale. In June 2023, a group of 30 philosophers and social scientists invited 20,085 scientists across 30 institutions in 12 countries to participate, gathering 6,807 responses to the statement 'Science has put it beyond reasonable doubt that COVID-19 is caused by a virus'. The study demonstrates that it is possible to establish a global network to quickly ascertain scientific opinion on a large international scale, with high response rate, low opt-out rate, and in a way that allows for significant (perhaps indefinite) repeatability. Measuring scientific opinion in this new way would be a valuable complement to currently available approaches, potentially informing policy decisions and public understanding across diverse fields.

We show that, like singular cardinals, and weakly compact cardinals, Jensen's core model K for measures of order zero [4] calculates correctly the successors of Jónsson cardinals, assuming $O^{Sword}$ does not exist. Namely, if $\kappa$ is a Jónsson cardinal then $\kappa^+ = \kappa^{+K}$ , provided that there is no non-trivial elementary embedding $j:K \longrightarrow K$ . There are a number of related results in ZFC concerning $\cal{P}(\kappa)$ in V and inner models, for $\kappa$ a Jónsson or singular cardinal.

Family involvement in healthcare decision-making for competent patients occurs to varying degrees in many communities around the world. There are different attitudes about who should make treatment decisions, how and why. Legal and professional ethics codes in most jurisdictions reflect and support the idea that competent patients should be enabled to make their own treatment decisions, even if others, including their healthcare professionals, disagree with them. This way of thinking contrasts with some cultural norms that put more emphasis on the (...) family as a decision-making entity, in some circumstances to the exclusion of a competent patient. Possible tensions may arise between various combinations of patient, family members and healthcare professionals, and healthcare professionals must tread a careful path in navigating family involvement in the decision-making process. These tensions may be about differences of opinion about which treatment option is best and/or on who should have a say or influence in the decision-making process. While some relevant cultural, legal and policy considerations vary from community to community, there are ethical issues that healthcare professionals need to grapple with in balancing the laws and professional codes on decision-making and the ethical principle of respecting patients and their autonomy. This paper will highlight and propose that a partial resolution to these issues may lie in relational understandings of autonomy, which in principle justify interventions by healthcare professionals and family that support patients in decision-making.

Therapeutic privilege is a defence that may be available to doctors who fail to disclose to the patient relevant information when seeking informed consent for treatment if they have a reasonable belief that providing that information would likely cause the patient concerned serious physical or mental harm. In a landmark judgement, the Singapore Court of Appeal introduced a novel interpretation of TP, identifying circumstances in which it might be used with patients who did not strictly lack capacity but might be (...) inclined to refuse recommended treatments. In this paper, we explore the conceptual and practical challenges of this novel interpretation of TP. We propose that more emphasis should be placed on forms of shared and supported decision-making that foster the autonomy of patients with compromised mental capacity while being mindful of the need to safeguard their well-being. The kind of privilege that doctors might need to invoke is one of time and supportive expertise to ensure a flexible, responsive approach calibrated to the individual patients’ needs. The provision of such service would extinguish the need for the novel TP proposed by the Singapore Court of Appeal. (shrink)

The import of Petrarch's description of Laura extends well beyond the confines of his own poetic age; in subsequent times, his portrayal of feminine beauty became authoritative. As a primary canonical text, the Rime sparse consolidated and disseminated a Renaissance mode. Petrarch absorbed a complex network of descriptive strategies and then presented a single, transformed model. In this sense his role in the history of the interpretation and the internalization of woman's "image" by both men and women can scarcely be (...) overemphasized. When late-Renaissance theorists, poets, and painters represented woman's body, Petrarch's verse justified their aesthetic choices. His authority, moreover, extended beyond scholarly consideration to courtly conversation, beyond the treatise on beauty to the after-dinner game in celebration of it. The descriptive codes of others, both ancients and contemporaries, were, of course, not ignored, but the "scattered rhymes" undeniably enjoyed a privileged status: they informed the Renaissance norm of a beautiful woman.1· 1.

We consider the following question of Kunen: Does Con(ZFC + ∃M a transitive inner model and a non-trivial elementary embedding j: M $\longrightarrow$ V) imply Con (ZFC + ∃ a measurable cardinal)? We use core model theory to investigate consequences of the existence of such a j: M → V. We prove, amongst other things, the existence of such an embedding implies that the core model K is a model of "there exists a proper class of almost Ramsey cardinals". Conversely, (...) if On is Ramsey, then such a j, M are definable. We construe this as a negative answer to the question above. We consider further the consequences of strengthening the closure assumption on j to having various classes of fixed points. (shrink)

Editors' introduction to 3rd thematic issue on philosophy of medicine.

Although there is a long tradition, going back at least to the tenth century, that would see Aristophanes' Birds as somehow related to the exile in Lacedaemon of Alcibiades, and to the fortification of the Attic township of Decelea by his Spartan hosts , current scholarship surrounding Birds is firmly in the hands of those who are antipathetic to seeing the creation of Cloudcuckooland in terms of a political allegory. ‘The majority of scholars today…flatly reject a political reading’; Birds has (...) ‘no strong and obvious connection with a topical question of public interest’; ‘attempts to find in Birds any extensive allegorical comment…are unconvincing’. Not only is it widely believed that ‘Birds… is strangely free of political concerns’. but also that ‘the theme of the Birds is absurdity itself…it is about meaninglessness’ . This is a tradition that descends from A. W. von Schlegel, for whom Birds was ‘merely a “Lustspiel”, full of imagination and the marvellous, with amusing touches at everything, but with no particular object’. This approach was reinforced by the fact that by the second half of the nineteenth century, the allegorists had apparently spun out of control. By 1879, there were no fewer than 79 accounts of the Tendenz of the Birds —some political, some ‘escapist fantasy’–on offer. The most influential allegorical interpretation of Birds was J. W. Suvern's study of 1826, but which is now generally dismissed, and only mentioned to be held up as a warning to those who might be tempted to take the allegorical route. This paper takes a different point of departure, namely Pierre Brumoy's Le thétre des grecs , an allegorical treatment that is full of good sense, and which was too hastily dismissed by Suvern, and ignored by others.

The essays in this volume are based on addresses given during a colloquium on free logic, modal logic, and related areas held at the University of California in 1968. The majority of the contributors are well known for their writings in these fields and their papers are as illuminating as they are technical. In the first paper, Lambert and Bas C. Van Fraassen apply free logic to several controversies in quantified modal logic. One of these is Putman's argument that 'Nothing (...) is both red and green all over' can be had as a theorem of modal logic. Lambert and Van Fraassen provide a counter example to this claim and then show that the argument only holds in systems allowing possible individuals. Jaako Hintikka's essay also deals with 'free' modal logics in much the same way as Hintikka's other papers and discusses some of the criticisms of Quine of the entire enterprise of quantified modal logic. In another paper, H. Leblanc and R. K. Meyer provide truth-value semantics for the theory of types and hence an alternative semantic structure for functional calculi of any order. In addition to these essays, there are papers by R. Thomason and Dana Scott on modal logic, J. Vickers on probability logic, and Peter Woodruff on truth value gaps. To anyone interested in these various areas this collection is sure to be welcome.--R. P. M. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 40.1 (2002) 121-122 [Access article in PDF] Book Review Humanism and Early Modern Philosophy Jill Kraye and M. W. F. Stone, editors. Humanism and Early Modern Philosophy. New York: Routledge, 2000. Pp. xii + 270. Cloth, $75.00 Early-modern philosophy begins in the seventeenth century. This book, based on a colloquium at the Warburg Institute, London in 1997, strives at extending the limits of (...) this period into the sixteenth and fifteenth centuries. Thus "the long-standing exclusion of the Renaissance from the standard philosophical curriculum" (xii) should come to an end by acknowledging its being an integral part of early modern philosophy and its relevance for an understanding of modern thought. The distinctive element of the Renaissance was, according to the editors, humanism, understood as the revival of ancient sources from the fourteenth century on, and its impact on the shaping of modern thought by these sources.One can identify the following types of argument offered in the twelve contributions to this book: (1) Renaissance humanists mediated classical sources into the seventeenth and following centuries either by translating Greek texts into Latin (Lohr on Aristotle commentaries) or by offering new interpretations that were to become standard (Hankins on Ficino and Galileo, and Mercer on the German Platonists). (2) Ancient modes of thought, mediated through the Renaissance, shaped modern philosophy (Stone on Aristotelian and Reformed ethics, Levi on Stoicism in Justus Lipsius, Kraye on Marcus Aurelius editions, and Osler on Gassendi and Aristotle). (3) Humanist literary forms and mentalities survived in modern thought (Bianchi on dialogue, Vickers on rhetoric in Bacon, and James on 'grandeur' and scientific argument).Two papers do not fit into this scheme: in "The Theology of Lorenzo Valla," the only paper dealing directly with a Renaissance humanist, Monfasani wants to prove that "Valla was no theologian." Monfasani does this on the basis of a very narrow concept of dogmatic correctness, blaming Valla continuously for being banal, to the effect that the paper does not contribute to the topic of the book. One could well connect Valla's theological issues (free will, summum bonum, trinity, etc.) with his provocative stirring up of philosophy in general and show his influence on Protestant theology and on modern ethics.The other paper is by J. R. Milton, which is enlightening because it summarizes the prejudices against humanism in modern philosophy ("'Delicate learning,' erudition and the enterprise of philosophy"). He endorses "one of the most familiar narratives in European philosophy" (161), namely that Descartes's breakthrough was due to his total rupture [End Page 121] with the philosophical tradition, especially with contemporary humanist and scholastic thought. Thus Descartes's triumph was that of the myth of the irrelevance of history to philosophy as evident in Galileo, Locke, and even Hume. If antecedents are acknowledged, e.g., in Berkeley, then accepting that they "provide us either with an irreplaceable source of wisdom or with equally irreplaceable models for imitation, or indeed both" (167), still fails to recognize that the history of a philosophical problem is a part of that problem rather than just some general "wisdom" or a model for imitation. Of course, Milton repeats the myth of Bacon's anti-humanism, masterly refuted in this very book by Brian Vickers, and Milton believes that Valla "enthroned" "custom and example" and therefore for him "it would be difficult if not impossible to state Hempel's Raven Paradox" (169). One might wonder whether the conclusion: "All ravens are black --all non-black things are non-ravens," is the paramount of modern philosophy. But a thorough reader of Valla's logic might discover similarities to pragmatism, which are fostered by his deep criticism of language with the tools of Renaissance humanism. However, Descartes's indebtedness to Renaissance method and rhetoric is handbook knowledge today.The audience for this collection of samples are specialists either in seventeenth- or eighteenth-century philosophy, or in Renaissance thought, or even philosophers in the narrow sense of the disciplines. The latter are difficult to convince of the usefulness of historic studies or "erudite activity" (Milton... (shrink)

Where does consciousness come from and how does it work? Is it a purely biological thing? Where does the brain leave off and the mind begin? These questions, once viewed as ethereal and impossible to study empirically, are now being addressed by science in bold and startling new ways.In Consciousness, world-renowned neuropsychiatrist J. Allan Hobson presents a witty and introspective consideration of this mysterious concept, connecting it to specific areas of the brain and their chemical and physical states. Hobson guides (...) his readers through the various states of waking, dreaming, and nonconsciousness using the theories and data of neuroscience, psychiatry, and neurophysiology. Although his ideas are based in science, his imaginative approach keeps us in touch with the mysterious and seductive nature of his subject.Richly woven, with references to literature, philosophy, and the author's personal experiences, Consciousness is a delightful and compact introduction to a concept central to the human experience.

Over the past twenty years, economic theory has begun to play a central role in antitrust matters. In earlier days, the application of antitrust rules was viewed almost entirely in formal terms; now it is widely accepted that the proper interpretation of these rules requires an understanding of how markets work and how firms can alter their efficient functioning. The Handbook of Antitrust Economics offers scholars, students, administrators, courts, companies, and lawyers the economist's view of the subject, describing the application (...) of newly developed theoretical models and improved empirical methods to antitrust and competition law in both the United States and the European Union. After a general discussion of the use of empirical methods in antitrust cases, the Handbook covers mergers, agreements, abuses of dominance, and market features that affect the way firms compete. Chapters examine such topics as analyzing the competitive effects of both horizontal and vertical mergers, detecting and preventing cartels, theoretical and empirical analysis of vertical restraints, state aids, the relationship of competition law to the defense of intellectual property, and the application of antitrust law to "bidding markets," network industries, and two-sided markets.ContributorsMark Armstrong, Jonathan B.

We would like to thank Dolega and Dewhurst for a thought-provoking and informed deconstruction of our article, which we take as applause from valued members of our audience. In brief, we fully concur with the theatre-free formulation offered by Dolega and Dewhurst and take the opportunity to explain why we used the Cartesian theatre metaphor. We do this by drawing an analogy between consciousness and evolution. This analogy is used to emphasize the circular causality inherent in the free energy principle. (...) We conclude with a comment on the special forms of active inference that may be associated with selfawareness and how they may be especially informed by dream states. (shrink)

J. Hillis Miller (1928–2021) was one of the most prominent figures in literary criticism and theory. After receiving his Ph.D. from Harvard University, he taught at Johns Hopkins University, Yale University and the University of California at Irvine. He retired as Professor Emeritus in 2002. Miller was president of the Modern Language Association of America in 1986 and contributed significantly to professional academic institutions and organizations throughout his career. As an important representative of the Yale School, he had close relationships (...) with Derrida, Paul de Man, Geoffrey Hartman and Harold Bloom. Dr. Ning Yizhong did postdoctoral research under his supervision at UCI from 1997 to 1998. This is part of his interviews with Professor Miller during that time. In this interview, Miller talks about the Yale School in general, and Jacques Derrida, Paul de Man and Harold Bloom in particular. 1. (shrink)

Prominent philosophers have argued that contradictions contain either too much or too little information to be useful. We dispute this with what we call the “Paradox of the Two Firefighters.” Suppose you are awakened in your hotel room by a fire alarm. You open the door. You see three possible ways out: left, right, straight ahead. You see two firefighters. One says there is exactly one safe route and it is to your left. The other says there is exactly one (...) safe route and it is to your right. While the two firemen are giving you contradictory information, they are also both giving you the perhaps useful information that there is a safe way out and it is not straight ahead. We give two analyses. The first uses the “Opinion Tetrahedron,” introduced by Dunn as a generalization of Audun Jøsang’s “Opinion Triangle.” The Opinion Tetrahedron in effect embeds the values of the “Belnap-Dunn 4-valued Logic” into a context of subjective probability generalized to allow for degrees of belief, disbelief, and two kinds of uncertainty—that in which the reasoner has too little information and that in which the reasoner has too much information. Jøsang had only a single value for uncertainty. We also present an alternative solution, again based on subjective probability but of a more standard type. This solution builds upon “linear opinion pooling.” Kiefer had already developed apparatus for assessing risk using expert opinion, and this influences the second solution. Finally, we discuss how these solutions might apply to “Big Data” and the World Wide Web. (shrink)

An important role of the philosopher is to critically reflect on what is often taken for granted, using the tools of argument and analysis. This article engages with six different papers that offer critical reflections on conventional concepts and beliefs in bioethics regarding informed consent, continuous deep sedation, traditional moral theories underlying bioethical thinking, the definition of mental disease, and codes of ethics for particular medical specialties.

Whereas previous research has focused on the link between workload and task performance, less is known about the intervening mechanisms influencing this relationship. In the present study, we test the moderating roles of daily recovery and total sleep time in the relationship between work pressure and daily task performance. Using performance and recovery theories, we hypothesized that work pressure relates positively to daily task performance, and that both daily recovery in the form of psychological detachment and relaxation, and total sleep (...) time independently enhance this relationship. Our hypotheses were tested in a 30-day diary study with 110 officer cadets on a cross-Atlantic voyage on a Naval sail ship. The results of multilevel modeling lend support to all three hypotheses. Taken together, our findings suggest that recovery and sleep duration between shifts play a key role in the relationship between daily work pressure and task performance. We discuss the implications of these findings for the stressor-detachment model. (shrink)

ABSTRACT Scholarship in the area of social movements points to the importance of inter-group collaboration and alliance building. In the case of Indigenous-led movements and the issue of solidarity with non-Indigenous movement participants, scholarship at the intersection of Native studies and social movements suggests that such alliances can be built and sustained but that unlearning colonial attitudes and behaviors is central to this process. Through in-depth interviews with non-Native solidarity participants, this article considers how engagement with Indigenous thought and action (...) re-shapes particpants’ conceptions of environment and place. Findings suggest that such involvement calls attention to histories of violence as well as ongoing practices of dispossession causing activists to grapple not only with their personal and family histories but also with their evolving relationship with environmentalism.

Evolving from both Gifford Pinchot and his utilitarian philosophy of wise use, and John Muir and the preservation philosophy of wilderness, Aldo Leopold espoused--and practices--integrating a degree of wildness into the working agricultural landscape. As newly published essays show, his articulation of "land health" prefigures current definitions of ecosystem health, and the practices he preached anticipate today's prescriptions for ecosystem management. Although the science of ecology has evolved and terminology has changed, Leopold's formulation may help both standardize and institutionalize the (...) concept of ecosystem health, and his example may inspire an ambitious new goal in public and private land management.

A Heyting algebra is supplemented if each element a has a dual pseudo-complement \, and a Heyting algebra is centrally supplement if it is supplemented and each supplement is central. We show that each Heyting algebra has a centrally supplemented extension in the same variety of Heyting algebras as the original. We use this tool to investigate a new type of completion of Heyting algebras arising in the context of algebraic proof theory, the so-called hyper-MacNeille completion. We show that the (...) hyper-MacNeille completion of a Heyting algebra is the MacNeille completion of its centrally supplemented extension. This provides an algebraic description of the hyper-MacNeille completion of a Heyting algebra, allows development of further properties of the hyper-MacNeille completion, and provides new examples of varieties of Heyting algebras that are closed under hyper-MacNeille completions. In particular, connections between the centrally supplemented extension and Boolean products allow us to show that any finitely generated variety of Heyting algebras is closed under hyper-MacNeille completions.
