I consider a quantum system that possesses key features of quantum shape dynamics and show that the evolution of wave-packets will become increasingly classical at late times and tend to evolve more and more like an expanding classical system. At early times however, semiclassical effects become large and lead to an exponential mismatch of the apparent scale as compared to the expected classical evolution of the scale degree of freedom. This quantum inflation of an emergent and effectively classical system, occurs (...) naturally in the quantum shape dynamics description of the system, while it is unclear whether and how it might arise in a constrained Hamiltonian quantization.

Moral theories can be distinguished, not only by the answers they give, but also by the questions they ask. Utilitarianism's central commitment is to the promotion of well-being, impartially considered. This commitment shapes utilitarianism in a number of ways. If scarce resources should be directed where they will best promote well-being, and if theoretical attention is a scarce resource, then moral theorists should focus on topics that are most important to the future promotion of well-being. A theme of this Element (...) is that, as times change, the priorities of utilitarianism also change. Questions that were once theoretical curiosities move centre stage. And themes from earlier utilitarians that have become unfashionable may come to the fore again. Utilitarianism is a living tradition, not an abstract set of timeless principles or a purely historical artefact. (shrink)

This study investigates the types of misinformation spread on Twitter that evokes scientific authority or evidence when making false claims about the antimalarial drug hydroxychloroquine as a treatment for COVID-19. Specifically, we examined tweets generated after former U.S. President Donald Trump retweeted misinformation about the drug using an unsupervised machine learning approach called the biterm topic model that is used to cluster tweets into misinformation topics based on textual similarity. The top 10 tweets from each topic cluster were content coded (...) for three types of misinformation categories related to scientific authority: medical endorsements of hydroxychloroquine, scientific information used to support hydroxychloroquine’s use, and a comparison group that included scientific evidence opposing hydroxychloroquine’s use. Results show a much higher volume of tweets featuring medical endorsements and use of supportive scientific information compared to accurate and updated scientific evidence, that misinformation-related tweets propagated for a longer time frame, and the majority of hydroxychloroquine Twitter discourse expressed positive views about the drug. Metadata from Twitter accounts found that prominent users within misinformation discourse were more likely to have media or political affiliation and explicitly expressed support for President Trump. Conversely, prominent accounts within the scientific opposition discourse primarily consisted of medical doctors or scientists but had far less influence in the Twitter discourse. Implications of these findings and connections to related social media research are discussed, as well as cognitive mechanisms for understanding susceptibility to misinformation and strategies to combat misinformation spread via online platforms.

Values based practice (VBP) is a radical view of the place of values in medicine which develops from a philosophical analysis of values, illness and the role of ethical principles. It denies two attractive and traditional but misguided views of medicine: that diagnosis is a merely factual matter and that the values that should guide treatment and management can be codified in principles. But, in the work of KWM (Bill) Fulford, it goes further in the form of a radical liberal (...) view: that the idea of an antecedently good outcome should be replaced by that of a right process. That however leads to a dilemma as to whether it can account for its own normative status. Given that difficulty, why might one adopt the radical version? I sketch a possible motive drawing on Rorty’s rejection of authoritarianism which replaces objectivity with solidarity as the aim of judgement. But I argue that, nevertheless, this does not justify the rejection of the more modest particularist version of VBP. (shrink)

Many passages in early Confucian texts such as the Analects and Mengzi are focused on virtue, recommending qualities like humaneness (ren 仁), righteousness (yi 義), and trustworthiness (xin 信). Still others emphasize roles: what it means to be a good son, a good ruler, a good friend, a good teacher, or a good student. How are these teachings about virtues and roles related? In the past decade there has been a growing debate between two interpretations of early Confucian ethics, one (...) that sees virtues as fundamental, and the other of which starts from roles. Recently there have been two new contributions to the debate: Virtue Ethics and Confucianism (2013), edited by Stephen C. Angle and Michael Slote, which develops the virtue ethical interpretation, and Henry Rosemont, Jr.’s Against Individualism: A Confucian Rethinking of the Foundations of Morality, Politics, Family, and Religion (2015), which defends the role-based interpretation. This paper lays out the main contours of the debate between Virtue Ethical Confucianism and Confucian Role Ethics, as well as examines the distinctive contributions of these two new works. (shrink)

This is a comprehensive resource of original essays by leading thinkers exploring the newly emerging interdisciplinary field of the philosophy of psychiatry. The contributors aim to define this exciting field and to highlight the philosophical assumptions and issues that underlie psychiatric theory and practice, the category of mental disorder, and rationales for its social, clinical, and legal treatment.

This paper examines the changing meanings of the concept of 'biology', and of its opposition to 'culture', through an analysis of the ways in which anthropologists have sought to refute the idea that humanity is divided into distinct races. Efforts to redefine all extant humans as belonging to a single sub-species, or to replace 'race' with 'culture', only serve to perpetuate raciological thinking. This kind of thinking had its origins in the moral evaluation of physical difference, the construction of hierarchy (...) and essentialist typology. In its 1996 'Statement on Race', the American Association of Physical Anthropologists ruled out any connection between the biological and cultural characteristics of human beings. Yet the statement is internally inconsistent in the meanings it attributes to both biology and culture. These shifts in meaning correspond to phases in the history of anthropology, identified here as the Enlightenment phase (culture as a process of civilisation drawing on universal biopsychological capacities), the Consensual phase (culture as diverse traditions inscribed upon a common biological substrate) and the Interactionist phase (behaviour as the product of an interaction between culturally and genetically transmitted information in a given environment). The paper seeks an alternative, relational approach that focuses on the dynamics of developmental systems. Only through such an approach, it is argued, can we wrest biology away from the combination of geneticism and essentialism that continues to perpetuate the logic of raciology even in the course of its vehement denial.

Eventualities and worlds are analysed uniformly as schedules of certain descriptions of eventuality-types (reversing the reduction of eventuality-types to eventualities). The temporal interpretation of modals in Condoravdi 2002 is reformulated to bring out what it is about eventualities and worlds that is essential to the account. What is essential, it is claimed, can be recovered from schedules that may or may not include worlds.

This issue opens an inquiry into the tension between solidity and fluidity. This tension is ingrained in the Western intellectual tradition and informs theoretical debates across the sciences and humanities. In physics, solid is one phase of matter, alongside liquid, gas and plasma. This, however, assumes all matter to be particulate. Reversing the relation between statics and dynamics, we argue to the contrary, that matter exists as continuous flux. It is both solid and fluid. What difference would it make were (...) we to start from our inescapable participation in a world of solid fluids? Is solid fluidity a condition of being in the midst of things, or of intermediacy on a solid-fluid continuum? Does the world appear fluid in the process of its formation, but solid when you look back on things already formed? Here we open new paths for theorizing matter and meaning at a time of ecological crisis. (shrink)

The principal aim of this article is to examine the relations between positioning and belonging in terms of the potential for critique of existing social conditions. The underlying purpose is to inform social scientific engagement with social life in order to illuminate the potential for social transformation via reflexivity. These discussions will be informed by the division of reflexivity into two dimensions: endogenous and referential. It is argued that this enables the social scientist to highlight the pre-reflexive world and render (...) it problematic and demonstrates how the objectivity of the social world is both a presupposition and ongoing achievement of everyday interactions. To that extent, the possibility for social conditions to be otherwise is then open to scrutiny. (shrink)

Person Centred Medicine is a substantial and contentious view of healthcare that carries both ontological and epistemological presuppositions. This chapter examines two key aspects: that the person is a central, basic irreducible element in ontology and that person-level knowledge is both important and possible. Some reasons for holding both of these are sketched.

Harry Collins’s Tacit and Explicit Knowledge characterises tacit knowledge through a number of antonyms: explicit, explicable, and then explicable via elaboration, transformation, mechanization and explanation and, most fundamentally, what can be communicated via “strings”. But his account blurs the distinction between knowledge and what knowledge can be of and has a number of counter-intuitive consequences. This is the result of his adoption of strings themselves rather than the use of words or signs as the mark of what is explicit and, (...) I suggest, it may stem from his earlier response to Wittgenstein’s rules regress. (shrink)

This letter responds to the article “On the Authority of Advance Euthanasia Directives for People with Severe Dementia: Reflections on a Dutch Case,” by Henri Wijsbek and Thomas Nys, in the September‐October 2022 issue of the Hastings Center Report.

This paper demonstrates that John Wheeler and Richard Feynman's strategy for avoiding causal paradoxes threatened by backward causation and time-travel can be defeated by designing self-interacting mechanisms with a non-simple topological structure. Time-travel therefore requires constraints on the allowable data on space-like hypersurfaces. The nature and significance of these constraints is discussed.

This paper discusses a role playing ethics case suitable for business students in which participants must balance shareholder and stakeholder concerns. Students take on the role of operations manager and are challenged to consider the effects of their choices on the local society as they balance the demands of stockholders, employees, and family when the concerns of the groups come into conflict. The exercise helps students understand the need to consider the ethicalcomponents of business decisions and the difficulties of handling (...) values in conflict. Students learn more about their own values through playing the role of manager. Suggested discussion questions are provided. This note also reviews some of the extant literature on the goals of stakeholder versus shareholder wealth and the role of ethics, and it discusses areas of common ground between the stakeholder/shareholder theories.

This paper looks at Sartre's 1957 papers on Jacopo Tintoretto to examine his reading of action and space in Tintoretto's St George and the Dragon . I suggest that Sartre offers an idea of grace which, far from shoring up a sense of decisive resolution to the action depicted in the painting, speaks instead of an abandonment in the subjective situation. This notion of abandonment appears through the erasure of a conclusive causal point, the disappearance of which lies at the (...) heart of Sartre's reading. Once freed from causal moorings existence is not loosened but rather becomes weighed down in its very situation. Taking support from the work of Levinas this paper considers how Sartre follows the cursive lines of this burdened subjectivity within the deceptive play of Tintoretto's painting. (shrink)

Shanker & King's (S&K's) dynamic systems approach converges with developments in social anthropological studies of communication which were long ago anticipated in the writings of Volosinov and Schutz. Following a review of these writings, this commentary suggests that a dynamic systems approach should distinguish communion from communication. It concludes with a remark on the evolutionary implications of the approach.

A common objection to _act consequentialism (AC) is that it makes unreasonable demands on moral agents. _Rule consequentialism (RC) is often presented as a less demanding alternative. It is argued that this alleged virtue of RC is false, as RC will not be any less demanding in practice than AC. It is then demonstrated that RC has an additional (hitherto unnoticed) vice, as it relies upon the undefended simplifying assumption that the best possible consequences would arise in a society in (...) which everyone followed the same rules. Once this "_homogeneity assumption" is rejected, RC is unable to provide a workable alternative to AC. (shrink)

Climate change has obvious practical implications. It will kill millions of people, wipe out thousands of species, and so on. My question in this paper is much narrower. How might climate change impact on moral theory – and especially on the debate between utilitarians and their non-utilitarian rivals? I argue that climate change creates serious theoretical difficulties for non-utilitarian moral theories – especially those that based morality or justice on any contract or bargain for reciprocal advantage. Climate change thus tips (...) the dialectical balance in favour of utilitarianism. However, I also argue that, because it upsets assumptions that lie behind the most plausible forms of modern utilitarianism, climate change may also push utilitarianism in a more austere and demanding direction.
