The self-interaction spin-2 approach to GR has been extremely influential in the particle physics community. Leaving no doubt regarding its heuristic value, we argue that any view of the metric field of GR as nothing but a stand-in for a self-coupling field in at spacetime runs into a dilemma: either the view is physically incomplete in so far as it requires recourse to GR after all, or it leads to an absurd multiplication of alternative viewpoints on GR rendering any understanding (...) of the metric field as nothing but a spin-2 field in at spacetime unjustified.

Human vision supports social perception by efficiently detecting agents and extracting rich information about their actions, goals, and intentions. Here, we explore the cognitive architecture of perceived animacy by constructing Bayesian models that integrate domain‐specific hypotheses of social agency with domain‐general cognitive constraints on sensory, memory, and attentional processing. Our model posits that perceived animacy combines a bottom–up, feature‐based, parallel search for goal‐directed movements with a top–down selection process for intent inference. The interaction of these architecturally distinct processes makes perceived (...) animacy fast, flexible, and yet cognitively efficient. In the context of chasing, in which a predator (the “wolf”) pursues a prey (the “sheep”), our model addresses the computational challenge of identifying target agents among varying numbers of distractor objects, despite a quadratic increase in the number of possible interactions as more objects appear in a scene. By comparing modeling results with human psychophysics in several studies, we show that the effectiveness and efficiency of human perceived animacy can be explained by a Bayesian ideal observer model with realistic cognitive constraints. These results provide an understanding of perceived animacy at the algorithmic level—how it is achieved by cognitive mechanisms such as attention and working memory, and how it can be integrated with higher‐level reasoning about social agency.

We investigated people's ability to infer others’ mental states from their emotional reactions, manipulating whether agents wanted, expected, and caused an outcome. Participants recovered agents’ desires throughout. When the agent observed, but did not cause the outcome, participants’ ability to recover the agent's beliefs depended on the evidence they got. When the agent caused the event, participants’ judgments also depended on the probability of the action ; when actions were improbable given the mental states, people failed to recover the agent's (...) beliefs even when they saw her react to both the anticipated and actual outcomes. A Bayesian model captured human performance throughout, consistent with the proposal that people rationally integrate information about others’ actions and emotional reactions to infer their unobservable mental states.

We can understand viewed scenes and extract task-relevant information within a few hundred milliseconds. This process is generally supported by three cortical regions that show selectivity for scene images: parahippocampal place area (PPA), medial place area (MPA) and occipital place area (OPA). Prior studies have focused on the visual information each region is responsive to, usually within the context of recognition or navigation. Here, we move beyond these tasks to investigate gaze allocation during scene viewing. Eye movements rely on a (...) scene’s visual representation to direct saccades, and thus foveal vision. In particular, we focus on the contribution of OPA, which is i) located in occipito-parietal cortex, likely feeding information into parts of the dorsal pathway critical for eye movements, and ii) contains strong retinotopic representations of the contralateral visual field. Participants viewed scene images for 1034 ms while their eye movements were recorded. On half of the trials, a 500 ms train of five transcranial magnetic stimulation (TMS) pulses was applied to the participant’s cortex, starting at scene onset. TMS was applied to the right hemisphere over either OPA or the occipital face area (OFA), which also exhibits a contralateral visual field bias but shows selectivity for face stimuli. Participants generally made an overall left-to-right, top-to-bottom pattern of eye movements across all conditions. When TMS was applied to OPA, there was an increased saccade latency for eye movements toward the contralateral relative to the ipsilateral visual field after the final TMS pulse (400ms). Additionally, TMS to the OPA biased fixation positions away from the contralateral side of the scene compared to the control condition, while the OFA group showed no such effect. There was no effect on horizontal saccade amplitudes. These combined results suggest that OPA might serve to represent local scene information that can then be utilized by visuomotor control networks to guide gaze allocation in natural scenes. (shrink)

BackgroundThe ARRIVE (Animal Research: Reporting of In Vivo Experiments) guidelines are widely endorsed but compliance is limited. We sought to determine whether journal-requested completion of an ARRIVE checklist improves full compliance with the guidelines.MethodsIn a randomised controlled trial, manuscripts reporting in vivo animal research submitted to PLOS ONE (March–June 2015) were randomly allocated to either requested completion of an ARRIVE checklist or current standard practice. Authors, academic editors, and peer reviewers were blinded to group allocation. Trained reviewers performed outcome adjudication (...) in duplicate by assessing manuscripts against an operationalised version of the ARRIVE guidelines that consists 108 items. Our primary outcome was the between-group differences in the proportion of manuscripts meeting all ARRIVE guideline checklist subitems.ResultsWe randomised 1689 manuscripts (control: n = 844, intervention: n = 845), of which 1269 were sent for peer review and 762 (control: n = 340; intervention: n = 332) accepted for publication. No manuscript in either group achieved full compliance with the ARRIVE checklist. Details of animal husbandry (ARRIVE subitem 9b) was the only subitem to show improvements in reporting, with the proportion of compliant manuscripts rising from 52.1 to 74.1% (X2 = 34.0, df = 1, p = 2.1 × 10−7) in the control and intervention groups, respectively.ConclusionsThese results suggest that altering the editorial process to include requests for a completed ARRIVE checklist is not enough to improve compliance with the ARRIVE guidelines. Other approaches, such as more stringent editorial policies or a targeted approach on key quality items, may promote improvements in reporting. (shrink)

We defend Joseph Melia's thesis that the role of mathematics in scientific theory is to 'index' quantities, and that even if mathematics is indispensable to scientific explanations of concrete phenomena, it does not explain any of those phenomena. This thesis is defended against objections by Mark Colyvan and Alan Baker.

We discuss a recent attempt by Chris Daly and Simon Langford to do away with mathematical explanations of physical phenomena. Daly and Langford suggest that mathematics merely indexes parts of the physical world, and on this understanding of the role of mathematics in science, there is no need to countenance mathematical explanation of physical facts. We argue that their strategy is at best a sketch and only looks plausible in simple cases. We also draw attention to how frequently Daly (...) and Langford find themselves in conflict with mathematical and scientific practice. (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)

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.

A timely, well-grounded analysis that reveals an inconvenient truth: we can't save capitalism and save the planet.

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.

Science and its philosophical companion, Naturalism, represent reality in wholly nonpersonal terms. How, if at all, can a nonpersonal scheme accommodate the first-person perspective that we all enjoy? In this volume, Lynne Rudder Baker explores that question by considering both reductive and eliminative approaches to the first-person perspective. After finding both approaches wanting, she mounts an original constructive argument to show that a non-Cartesian first-person perspective belongs in the basic inventory of what exists. That is, the world that contains (...) us persons is irreducibly personal.After arguing for the irreducibilty and ineliminability of the first-person perspective, Baker develops a theory of this perspective. The first-person perspective has two stages, rudimentary and robust. Human infants and nonhuman animals with consciousness and intentionality have rudimentary first-person perspectives. In learning a language, a person acquires a robust first-person perspective: the capacity to conceive of oneself as oneself, in the first person. By developing an account of personal identity, Baker argues that her theory is coherent, and she shows various ways in which first-person perspectives contribute to reality. (shrink)

We have good reason to believe that Nicomachean Ethics VI. 2 is a Nicomachean revision of an originally Eudemian text. Aristotle seems to have inserted lines 1139a31-b11 by means of a marginal note, which the first editor then mistakenly added in the wrong place, and I propose that we move these lines so that they follow the word κοινωνεῖν at 1139a20. The suggested note appears to be Nicomachean for several reasons but most importantly because it contains a desire-based account of (...) the practical intellect as teleologically oriented to action. The NE articulates consequences of this account regarding practical philosophy’s methodology and teleological orientation to action. The EE does not articulate such consequences, and instead seems to assume an object-based account of the practical intellect. Consequently, it would seem that, between the EE and the NE, Aristotle revised his conception of the practical intellect and consequently his conception of practical philosophy. (shrink)

My aim is twofold: first, to root out the metaphysical assumptions that generate the problem of mental causation and to show that they preclude its solution; second, to dissolve the problem of mental causation by motivating rejection of one of the metaphysical assumptions that give rise to it. There are three features of this metaphysical background picture that are important for our purposes. The first concerns the nature of reality: all reality depends on physical reality, where physical reality consists of (...) a network of events.1 The second concerns the nature of causation, and the third concerns the conception of behavior. I try to vindicate a robust idea of mental causation. (shrink)

Persons and Bodies develops and defends an account of persons and of the relation between human persons and their bodies. Human persons are constituted by bodies, without being identical to the bodies that constitute them—just as, I argue, statues are constituted by pieces of bronze, say, without being identical to the pieces of bronze that constitute them. The relation of constitution, therefore, is not peculiar to persons and their bodies, but is pervasive in the natural world.

Explaining Attitudes offers an important challenge to the dominant conception of belief found in the work of such philosophers as Dretske and Fodor. According to this dominant view beliefs, if they exist at all, are constituted by states of the brain. Lynne Rudder Baker rejects this view and replaces it with a quite different approach - practical realism. Seen from the perspective of practical realism, any argument that interprets beliefs as either brain states or states of immaterial souls is (...) a 'non-starter'. Practical realism takes beliefs to be states of the whole persons, rather like states of health. What a person believes is determined by what a person would do, say and think in various circumstances. Thus beliefs and other attitudes are interwoven into an integrated, commonsensical conception of reality. (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.

Self-consciousness, many philosophers agree, is essential to being a person. There is not so much agreement, however, about how to understand what self-consciousness is. Philosophers in the field of cognitive science tend to write off self-consciousness as unproblematic. According to such philosophers, the real difficulty for the cognitive scientist is phenomenal consciousness--the fact that we have states that feel a certain way. If we had a grip on phenomenal consciousness, they think, self-consciousness could be easily handled by functionalist models. For (...) example, recently Ned Block commented. (shrink)

Was Descartes a Cartesian Dualist? In this controversial study, Gordon Baker and Katherine J. Morris argue that, despite the general consensus within philosophy, Descartes was neither a proponent of dualism nor guilty of the many crimes of which he has been accused by twentieth century philosophers. In lively and engaging prose, Baker and Morris present a radical revision of the ways in which Descartes' work has been interpreted. Descartes emerges with both his historical importance assured and his philosophical (...) importance redeemed. (shrink)

"This book is a comprehensive attack on several of the views that have been most influential in the philosophy of psychology during the last two decades. Professor Baker argues that mentalistic notions should not be eliminated, and need not be explained in terms of other notions, in cognitive science.' The book is interesting and shows an honest concern for clear argumentation. It deserves a wide readership." --Tyler Burge, University of California at Los Angeles"This book is a provocative and relentlessly (...) argued treatment of a deep and important topic: the fate of intentionality. Baker's arguments oblige those who wish to defend the current conception of cognitive science to rethink the discipline. She has put the ball squarely in the physicalists' court. ... Despite the technical character of the topic, the book is wonderfully readable."--John Heil, Visiting Fellow, University of California, BerkeleyThis stimulating book critically examines a wide range of physicalistic conceptions of mind in the works of Jerry A. Fodor, Stephen P. Stich, Paul M. Churchland, Daniel C. Dennett, and others. Part I argues that intentional concepts cannot be reduced to nonintentional (and nonsemantic) concepts; Part II argues that intentional concepts are nevertheless indispensable to our cognitive enterprises and thus need no foundation in physicalism.As a sustained challenge to the prevailing interpretation of cognitive science, this timely book fills a large gap in the philosophical literature. It is sure to spark controversy, yet its clarity makes it attractive as a text in upper-level undergraduate and graduate courses in philosophy of mind and cognitive science. Saving Belief should be read byphilosophers, psychologists, and others interested in the philosophy of language, philosophy of mind, and cognitive science. (shrink)
