Mark Doyle's Utopian and Dystopian Themes in Tolkien's Legendarium reads Tolkien's work through the history of utopian and dystopian thought. The aim of this new study is not to prove that Tolkien set out to write dystopian fiction or create a blueprint for a utopian society, but that utopian and dystopian societies and settings crucially inform his legendarium. By placing his study outside of its usual fantasy context, Doyle gives us a valuable societally focused and historicized contribution to both Tolkien (...) and utopian studies respectively, yet one occasionally marred by the author's own unexamined value judgments.The book examines several aspects of Tolkien's legendarium, from its utopian and dystopian literary...

Anna Vaninskaya's Fantasies of Time and Death: Dunsany, Eddison, Tolkien brings together three major writers of fantasy and studies their treatment of temporality and mortality. This book is about our ongoing conversation regarding time and death and the unique ability for fantasy to tackle these biggest of subjects. If writers have long envisioned time as a river and death as the sea, for instance, what Vaninskaya's new book discusses is how fantasy allows us, through the use of impossible creations and (...) new metaphors, to imagine new ways of understanding our ontological trap. The genre attempts to try to see the world as one of the gods creating it, or to understand time as the eternal burden of the elves; we may... (shrink)

My remarks in this brief commentary focus on Chris Calvert-Minor’s (2014) article on Karen Barad’s philosophical writings, and are only indirectly relevant to an assessment of Barad’s work. I have limited acquaintance with Barad’s writings, and even less with Nils Bohr’s. Barad explicitly borrows from Bohr’s theoretical writings when developing her version of feminist epistemology. Barad’s recruitment of Bohr to support her philosophy creates a dilemma for me and other readers who are not conversant with Bohr’s physics/philosophy. To my (...) understanding, the general lessons that Barad draws from Bohr about physical phenomena seem roughly in line with Husserl’s conception of phenomena or Merleau-Ponty’s account of “the intertwining,”Barad is not the first to identify a phenomenological position with a feminist standpoint (see Smith 1992). Although she refers to the tendency to feminize “nature” as the passive object of science, she distinguishes her feminist view of “nature as agent” from. (shrink)

Humanism is blurry. It can have some clarity, but it is mainly blurry. To say anything otherwise is to fool oneself. Yes, we can construct reasonable humanistic theories that attempt to organize our understanding, such as methodologicalhumanism where one unifies discourses or practices according to human subjects or substantivehumanism that touts the importance of humanity via some shared attribute or substance. But to suggest that one can delineate and define the full salience of humanity, whether great or small, in the (...) world we live and understand is to suppose a divine clarity that eludes our possession. Theorists use terms like ‘social causes,’ ‘matter,’ ‘construction,’ and ‘interpretation’ to help us figure out how our cognition and rationality work, and yet they woefully fail to capture the richness of our experiences, which blur distinctions between society and matter all the time. Every account of humanism should take stock of this difficulty, being careful to say only what one. (shrink)

Eight prominent historians and social scientists give their perspectives on the fate of Marxist approaches to history and the direction of the discipline in coming decades. The volume offers rigorous and approachable analysis from several political and intellectual positions and will be an important contribution to current historical debates.

We define a program size complexity function $H^\infty$ as a variant of the prefix-free Kolmogorov complexity, based on Turing monotone machines performing possibly unending computations. We consider definitions of randomness and triviality for sequences in ${\{0,1\}}^\omega$ relative to the $H^\infty$ complexity. We prove that the classes of Martin-Löf random sequences and $H^\infty$-random sequences coincide and that the $H^\infty$-trivial sequences are exactly the recursive ones. We also study some properties of $H^\infty$ and compare it with other complexity functions. In particular, $H^\infty$ (...) is different from $H^A$, the prefix-free complexity of monotone machines with oracle A. (shrink)

This book provides a systematic analysis of many common argumentation schemes and a compendium of 96 schemes. The study of these schemes, or forms of argument that capture stereotypical patterns of human reasoning, is at the core of argumentation research. Surveying all aspects of argumentation schemes from the ground up, the book takes the reader from the elementary exposition in the first chapter to the latest state of the art in the research efforts to formalize and classify the schemes, outlined (...) in the last chapter. It provides a systematic and comprehensive account, with notation suitable for computational applications that increasingly make use of argumentation schemes. (shrink)

The primary purpose of Institutional Review Boards (IRBs) is to protect the rights and welfare of human research participants. Evaluation and measurement of how IRBs satisfy this purpose and other important goals are open questions that demand empirical research. Research on IRBs, and the Human Research Protection Programs (HRPPs) of which they are often a part, is necessary to inform evidence-based practices, policies, and approaches to quality improvement in human research protections. However, to date, HRPP and IRB engagement in empirical (...) research about their own activities and performance has been limited. To promote engagement of HRPPs and IRBs in self-reflective research on HRPP and IRB quality and effectiveness, barriers to their participation need to be addressed. These include: extensive workloads, limited information technology systems, and few universally accepted or consistently measured metrics for HRPP/irb quality and effectiveness. Additionally, institutional leaders may have concerns about confidentiality. Professional norms around the value of participating in this type of research are lacking. Lastly, obtaining external funding for research on IRBs and HRPPs is challenging. As a group of HRPP professionals and researchers actively involved in a research consortium focused on IRB quality and effectiveness, we identify potential levers for supporting and encouraging HRPP and IRB engagement in research on quality and effectiveness. We maintain that this research should be informed by the core principles of patient- and community-engaged research, in which members and key stakeholders of the community to be studied are included as key informants and members of the research team. This ensures that relevant questions are asked and that data are interpreted to produce meaningful recommendations. As such, we offer several ways to increase the participation of HRPP professionals in research as participants, as data sharers, and as investigators. (shrink)

For the past few decades postmodernism has been at the center of debates about philosophy, history, culture, and politics, including feminist theory and politics. Its theoretical rationale can be found in poststructuralist modes of social and cultural analysis and its concerns are echoed in postmodern cultural practices. The range of theories broadly described as “postmodern” includes writers as diverse as Lyotard, Baudrillard, Derrida, Lacan and Foucault. Among women theorists Julia Kristeva and Luce Irigaray have been particularly important.

From gender and identity to welfare and consumerism, sociology is the study of how societies are organized and what helps them function or go wrong. Questions posed include: What is my "tribe"? Why do people commit crimes? Who decides if someone has a mental illness? What's work for? Does aid do any good? Heads Up Sociology explores these fascinating questions and more.

Minimalists generally see themselves as engaged in a descriptive project. They maintain that they can explain everything we want to say about truth without appealing to anything other than the T-schema, i.e., the idea that the proposition that p is true iff p. I argue that despite recent claims to the contrary, minimalists cannot explain one important belief many people have about truth, namely, that truth is good. If that is so, then minimalism, and possibly deflationism as a whole, must (...) be rejected or recast as a profoundly revisionary project. (shrink)

Gene–environment covariance is the phenomenon whereby genetic differences bias variation in developmental environment, and is particularly problematic for assigning genetic and environmental causation in a heritability analysis. The interpretation of these cases has differed amongst biologists and philosophers, leading some to reject the utility of heritability estimates altogether. This paper examines the factors that influence causal reasoning when G–E covariance is present, leading to interpretive disagreement between scholars. It argues that the causal intuitions elicited are influenced by concepts of agency (...) and blame-worthiness, and are intimately tied with the conceptual understanding of the phenotype under investigation. By considering a phenotype-specific approach, I provide an account as to why causal ascriptions can differ depending on the interpreter. Phenotypes like intelligence, which have been the primary focus of this debate, are more likely to spark disagreement for the interpretation of G–E covariance cases because the concept and ideas about its ‘normal development’ relatively ill-defined and are a subject of debate. I contend that philosophical disagreement about causal attributions in G–E covariance cases are in essence disagreements regarding how a phenotype should be defined and understood. This moves the debate from one of an ontological flavour concerning objective causal claims, to one concerning the conceptual, normative and semantic dependencies. (shrink)

We consider the question of randomness of the probability ΩU[X] that an optimal Turing machine U halts and outputs a string in a fixed set X. The main results are as follows: ΩU[X] is random whenever X is $\Sigma _{n}^{0}$-complete or $\Pi _{n}^{0}$-complete for some n ≥ 2. However, for n ≥ 2, ΩU[X] is not n-random when X is $\Sigma _{n}^{0}$ or $\Pi _{n}^{0}$ Nevertheless, there exists $\Delta _{n+1}^{0}$ sets such that ΩU[X] is n-random. There are $\Delta _{2}^{0}$ sets (...) X such that ΩU[X] is rational. Also, for every n ≥ 1, there exists a set X which is $\Delta _{n+1}^{0}$ and $\Sigma _{n}^{0}$-hard such that ΩU[X] is not random. We also look at the range of ΩU as an operator. We prove that the set {ΩU[X]: X ⊆ 2<ω} is a finite union of closed intervals. It follows that for any optimal machine U and any sufficiently small real r, there is a set X ⊆ 2<ω recursive in ∅′ ⊕ r, such that ΩU[X] = r. The same questions are also considered in the context of infinite computations, and lead to similar results. (shrink)

Using possibly infinite computations on universal monotone Turing machines, we prove Martin-Löf randomness in ∅' of the probability that the output be in some set.

Human microbiome research makes causal connections between entire microbial communities and a wide array of traits that range from physiological diseases to psychological states. To evaluate these causal claims, we first examine a well-known single-microbe causal explanation: of Helicobacter pylori causing ulcers. This apparently straightforward causal explanation is not so simple, however. It does not achieve a key explanatory standard in microbiology, of Koch’s postulates, which rely on manipulations of single-microorganism cultures to infer causal relationships to disease. When Koch’s postulates (...) are framed by an interventionist causal framework, it is clearer what the H. pylori explanation achieves and where its explanatory strengths lie. After assessing this ‘simple’, single-microbe case, we apply the interventionist framework to two key areas of microbiome research, in which obesity and mental health states are purportedly explained by microbiomes. Despite the experimental data available, interventionist criteria for explanation show that many of the causal claims generated by microbiome research are weak or misleading. We focus on the stability, specificity and proportionality of proposed microbiome causal explanations, and evaluate how effectively these dimensions of causal explanation are achieved in some promising avenues of research. We suggest some conceptual and explanatory strategies to improve how causal claims about microbiomes are made. (shrink)

Recent clinical trials show that psychedelics such as LSD and psilocybin can be given safely in controlled conditions, and can cause lasting psychological benefits with one or two administrations. Supervised psychedelic sessions can reduce symptoms of anxiety, depression, and addiction, and improve well-being in healthy volunteers, for months or even years. But these benefits seem to be mediated by "mystical" experiences of cosmic consciousness, which prompts a philosophical concern: do psychedelics cause psychological benefits by inducing false or implausible beliefs about (...) the metaphysical nature of reality? This book is the first scholarly monograph in English devoted to the philosophical analysis of psychedelic drugs. Its central focus is the apparent conflict between the growing use of psychedelics in psychiatry and the philosophical worldview of naturalism. Within the book, Letheby integrates empirical evidence and philosophical considerations in the service of a simple conclusion: this "Comforting Delusion Objection" to psychedelic therapy fails. While exotic metaphysical ideas do sometimes come up, they are not, on closer inspection, the central driver of change in psychedelic therapy. Psychedelics lead to lasting benefits by altering the sense of self, and changing how people relate to their own minds and lives-not by changing their beliefs about the ultimate nature of reality. The upshot is that a traditional conception of psychedelics as agents of insight and spirituality can be reconciled with naturalism (the philosophical position that the natural world is all there is). Controlled psychedelic use can lead to genuine forms of knowledge gain and spiritual growth-even if no Cosmic Consciousness or transcendent divine Reality exists. Philosophy of Psychedelics is an indispensable guide to the literature for researchers already engaged in the field of psychedelic psychiatry, and for researchers-especially philosophers-who want to become acquainted with this increasingly topical field.

In the 1980s, philosophical, historical and social studies of science underwent a change which later evolved into a turn to practice. Analysts of science were asked to pay attention to scientific practices in meticulous detail and along multiple dimensions, including the material, social and psychological. Following this turn, the interest in scientific practices continued to increase and had an indelible influence in the various fields of science studies. No doubt, the practice turn changed our conceptions and approaches of science, but (...) what did it really teach us? What does it mean to study scientific practices? What are the general lessons, implications, and new challenges? This volume explores questions about the practice turn using both case studies and theoretical analysis. The case studies examine empirical and mathematical sciences, including the engineering sciences. The volume promotes interactions between acknowledged experts from different, often thought of as conflicting, orientations. It presents contributions in conjunction with critical commentaries that put the theses and assumptions of the former in perspective. Overall, the book offers a unique and diverse range of perspectives on the meanings, methods, lessons, and challenges associated with the practice turn. (shrink)

This paper is an enquiry into the logical, metaphysical, and physical possibility of time travel understood in the sense of the existence of closed worldlines that can be traced out by physical objects. We argue that none of the purported paradoxes rule out time travel either on grounds of logic or metaphysics. More relevantly, modern spacetime theories such as general relativity seem to permit models that feature closed worldlines. We discuss, in the context of Gödel's infamous argument for the ideality (...) of time based on his eponymous spacetime, what this apparent physical possibility of time travel means. Furthermore, we review the recent literature on so-called time machines, i.e., of devices that produce closed worldlines where none would have existed otherwise. Finally, we investigate what the implications of the quantum behaviour of matter for the possibility of time travel might be and explicate in what sense time travel might be possible according to leading contenders for full quantum theories of gravity such as string theory and loop quantum gravity.

Users of psychedelic drugs often report that their sense of being a self or ‘I’ distinct from the rest of the world has diminished or altogether dissolved. Neuroscientific study of such ‘ego dissolution’ experiences offers a window onto the nature of self-awareness. We argue that ego dissolution is best explained by an account that explains self-awareness as resulting from the integrated functioning of hierarchical predictive models which posit the existence of a stable and unchanging entity to which representations are bound. (...) Combining recent work on the ‘integrative self' and the phenomenon of self-binding with predictive processing principles yields an explanation of ego dissolution according to which self-representation is a useful Cartesian fiction: an ultimately false representation of a simple and enduring substance to which attributes are bound which serves to integrate and unify cognitive processing across levels and domains. The self-model is not a mere narrative posit, as some have suggested; it has a more robust and ubiquitous cognitive function than that. But this does not mean, as others have claimed, that the self-model has the right attributes to qualify as a self. It performs some of the right kinds of functions, but it is not the right kind of entity. Ego dissolution experiences reveal that the self-model plays an important binding function in cognitive processing, but the self does not exist. (shrink)

The chapter introduces and characterizes the notion of fittingness. It charts the history of the relation and its relevance to contemporary debates in normative and metanormative philosophy and proceeds to survey issues to do with fittingness covered in the volume’s chapters, including the nature and epistemology of fittingness, the relations between fittingness and reasons, the normativity of fittingness, fittingness and value theory, and the role of fittingness in theorizing about responsibility. The chapter concludes with a brief discussion of issues to (...) do with fittingness that aren’t covered extensively by the volume’s chapters in order to indicate avenues for further research.

The second edition of Doing Ethics in Media continues its mission of providing an accessible but comprehensive introduction to media ethics, with a theoretical grounding in moral philosophy, to help students think clearly and systematically about dilemmas in the rapidly changing media environment. Each chapter highlights specific considerations, cases, and practical applications for the fields of journalism, advertising, digital media, entertainment, public relations, and social media. Six fundamental decision-making questions - the "5Ws and H" around which the book is organized (...) - provide a path for students to articulate the issues; understand applicable law and ethics codes; consider the needs of stakeholders; work through conflicting values; integrate philosophic principles; and pose a "test of publicity." Students are challenged to be active ethical thinkers through the authors' reader-friendly style and use of critical early-career examples. While most people will change careers several times during their lives, all of us are life-long media consumers, and Doing Ethics in Media prepares readers for that task. Doing Ethics in Media is aimed at undergraduate and graduate students studying media ethics in mass media, journalism, and media studies. It also serves students in rhetoric, popular culture, communication studies, and interdisciplinary social sciences. The book's companion website-doingethicsin.media, or www.doingmediaethics.com-provides continuously updated real-world media ethics examples and collections of essays from experts and students. The site also hosts ancillary materials for students and for instructors, including a test bank and instructor's manual. (shrink)

> Wealthy nations must step up support for Africa and vulnerable countries in addressing past, present and future impacts of climate change The 2022 report of the Intergovernmental Panel on Climate Change paints a dark picture of the future of life on earth, characterised by ecosystem collapse, species extinction and climate hazards such as heatwaves and floods.1 These are all linked to physical and mental health problems, with direct and indirect consequences of increased morbidity and mortality. To avoid these catastrophic (...) health effects across all regions of the globe, there is broad agreement—as 231 health journals argued together in 2021—that the rise in global temperature must be limited to <1.5°C compared with pre-industrial levels. While the Paris Agreement of 2015 outlines a global action framework that incorporates providing climate finance to low-income and middle-income countries, this support has yet to materialise.2 COP27 is the fifth Conference of the Parties (COP) to be organised in Africa since its inception in 1995. Ahead of this meeting, we—as health journal editors from across the continent—call for urgent action to ensure it is the COP that finally delivers climate justice for Africa and vulnerable countries. This is essential for the health of those countries, and for the health of the whole world. The climate crisis has had an impact on the environmental and social determinants of health across Africa, leading to devastating health effects.3 Impacts on health can result directly from environmental shocks and indirectly through socially mediated effects.4 Climate change-related risks in Africa include flooding, drought, heatwaves, reduced food production and reduced labour productivity.5 Droughts in sub-Saharan Africa ….

The moral enhancement of humans by biological or genetic means has recently been urged as a response to the pressing concerns facing human civilization. In this paper, I argue that proponents of biological moral enhancement have misrepresented the facts of human moral psychology. As a result, the likely effectiveness of traditional methods of moral enhancement has been underestimated, relative to biological or genetic means. I review arguments in favor of biological moral enhancement and argue that the complexity of moral psychology (...) raises serious problems for such interventions. I offer a programmatic sketch of the ways in which our improved understanding of moral psychology can help facilitate more traditional methods of moral enhancement. I conclude that the best response to the dangers faced by human civilization is the continued use of traditional methods of moral enhancement and the use of our improved understanding of moral psychology to further refine and develop these methods.

When payment is offered for controlled human infection model research, ethical concerns may be heightened due to unfamiliarity with this study design as well as perceptions—and misperceptions—regarding risk. Against this backdrop, we commend Grimwade et al 1 for their careful handling of the relevant issues, coupling empirical and conceptual approaches. We agree with foundational elements of the authors’ analysis, including the acceptability of payment for research risk.1 However, in our view, it is preferable to treat payment for risk as a (...) discretionary incentive to achieve adequate recruitment and retention, rather than compensation owed as a matter of fairness. Grimwade et al 1 note that although their ‘Payment for Risk Model’ was ‘created specifically in the context of CHIM research, it has the potential to inform payment in other areas of medical research.’ We agree and would go further: we do not need a special payment framework for CHIMs because there is nothing so novel about them compared with other types of research as to demand a distinct approach. Any successful payment framework must address the following ethical issues: preserving informed consent ; treating participants fairly ; encouraging adequate recruitment and retention; avoiding deception by participants; and preserving public trust.2 Some of these issues may have particular salience in the context of CHIMs, but this study design does not demand consideration of entirely distinct ethical factors when evaluating offers of payment.2 We also agree with Grimwade et al 1 about several other key points.2 Given the burdens involved and ….
