Wilhelm (Forthcom Synth 199:6357–6369, 2021) has recently defended a criterion for comparing structure of mathematical objects, which he calls Subgroup. He argues that Subgroup is better than SYM \(^*\), another widely adopted criterion. We argue that this is mistaken; Subgroup is strictly worse than SYM \(^*\). We then formulate a new criterion that improves on both SYM \(^*\) and Subgroup, answering Wilhelm’s criticisms of SYM \(^*\) along the way. We conclude by arguing that no criterion that looks only to the (...) automorphisms of mathematical objects to compare their structure can be fully satisfactory. (shrink)

In this paper, we examine the relationship between general relativity and the theory of Einstein algebras. We show that according to a formal criterion for theoretical equivalence recently proposed by Halvorson and Weatherall, the two are equivalent theories.

A classic result in the foundations of Yang-Mills theory, due to J. W. Barrett ["Holonomy and Path Structures in General Relativity and Yang-Mills Theory." Int. J. Th. Phys. 30, ], establishes that given a "generalized" holonomy map from the space of piece-wise smooth, closed curves based at some point of a manifold to a Lie group, there exists a principal bundle with that group as structure group and a principal connection on that bundle such that the holonomy map corresponds (...) to the holonomies of that connection. Barrett also provided one sense in which this "recovery theorem" yields a unique bundle, up to isomorphism. Here we show that something stronger is true: with an appropriate definition of isomorphism between generalized holonomy maps, there is an equivalence of categories between the category whose objects are generalized holonomy maps on a smooth, connected manifold and whose arrows are holonomy isomorphisms, and the category whose objects are principal connections on principal bundles over a smooth, connected manifold. This result clarifies, and somewhat improves upon, the sense of "unique recovery" in Barrett's theorems; it also makes precise a sense in which there is no loss of structure involved in moving from a principal bundle formulation of Yang-Mills theory to a holonomy, or "loop", formulation.

Consciousness emerges as the key topic in this second edition of Owen Flanagan's popular introduction to cognitive science and the philosophy of psychology....

This volume presents cutting-edge theory and research on emotions as constructed events rather than fixed, essential entities. It provides a thorough introduction to the assumptions, hypotheses, and scientific methods that embody psychological constructionist approaches. Leading scholars examine the neurobiological, cognitive/perceptual, and social processes that give rise to the experiences Western cultures call sadness, anger, fear, and so on. The book explores such compelling questions as how the brain creates emotional experiences, whether the "ingredients" of emotions also give rise to other (...) mental states, and how to define what is or is not an emotion. Introductory and concluding chapters by the editors identify key themes and controversies and compare psychological construction to other theories of emotion. (shrink)

A self-fulfilling prophecy is, roughly, a prediction that brings about its own truth. Although true predictions are hard to fault, self-fulfilling prophecies are often regarded with suspicion. In this article, we vindicate this suspicion by explaining what self-fulfilling prophecies are and what is problematic about them, paying special attention to how their problems are exacerbated through automated prediction. Our descriptive account of self-fulfilling prophecies articulates the four elements that define them. Based on this account, we begin our critique by showing (...) that typical self-fulfilling prophecies arise due to mistakes about the relationship between a prediction and its object. Such mistakes—along with other mistakes in predicting or in the larger practical endeavor—are easily overlooked when the predictions turn out true. Thus we note that self-fulfilling prophecies prompt no error signals; truth shrouds their mistakes from humans and machines alike. Consequently, self-fulfilling prophecies create several obstacles to accountability for the outcomes they produce. We conclude our critique by showing how failures of accountability, and the associated failures to make corrections, explain the connection between self-fulfilling prophecies and feedback loops. By analyzing the complex relationships between accuracy and other evaluatively significant features of predictions, this article sheds light both on the special case of self-fulfilling prophecies and on the ethics of prediction more generally.

Currently, there is widespread skepticism that higher cognitive processes, given their apparent flexibility and globality, could be carried out by specialized computational devices, or modules. This skepticism is largely due to Fodor’s influential definition of modularity. From the rather flexible catalogue of possible modular features that Fodor originally proposed has emerged a widely held notion of modules as rigid, informationally encapsulated devices that accept highly local inputs and whose opera- tions are insensitive to context. It is a mistake, however, to (...) equate such features with computational devices in general and therefore to assume, as Fodor does, that higher cognitive processes must be non-computational. Of the many possible non-Fodorean architectures, one is explored here that offers possible solutions to computational problems faced by conventional modular systems: an ‘enzymatic’ architecture. Enzymes are computational devices that use lock-and-key template matching to iden- tify relevant information (substrates), which is then operated upon and returned to a common pool for possible processing by other devices. Highly specialized enzymes can operate together in a common pool of information that is not pre-sorted by information type. Moreover, enzymes can use molecular ‘tags’ to regulate the operations of other devices and to change how particular substrates are construed and operated upon, allowing for highly interactive, context-specific processing. This model shows how specialized, modular processing can occur in an open system, and suggests that skepti- cism about modularity may largely be due to failure to consider alternatives to the standard model.

Kant’s arguments for the reality of human freedom and the normativity of the moral law continue to inspire work in contemporary moral philosophy. Many prominent ethicists invoke Kant, directly or indirectly, in their efforts to derive the authority of moral requirements from a more basic conception of action, agency, or rationality. But many commentators have detected a deep rift between the _Groundwork for the Metaphysics of Morals_ and the _Critique of Practical Reason_, leaving Kant’s project of justification exposed to conflicting (...) assessments and interpretations. In this major re-reading of Kant, Owen Ware defends the controversial view that Kant’s mature writings on ethics share a unified commitment to the moral law’s primacy. Using both close analysis and historical contextualization, Owen Ware overturns a paradigmatic way of reading Kant’s arguments for morality and freedom, situating them within Kant’s critical methodology at large. The result is a novel understanding of Kant that challenges much of what goes under the banner of Kantian arguments for moral normativity today. (shrink)

Psychological construction constitutes a different paradigm for the scientific study of emotion when compared to the current paradigm that is inspired by faculty psychology. This new paradigm is more consistent with the post-Darwinian conceptual framework in biology that includes a focus on (a) population thinking (vs. typologies), (b) domain-general core systems (vs. physical essences), and (c) constructive analysis (vs. reductionism). Three psychological construction approaches (the OCC model, the iterative reprocessing model, and the conceptual act theory) are discussed with respect to (...) these ideas. (shrink)

Widely recognized as the finest definition of existentialist Philosophy, this book introduced existentialism to America in 1958. Barrett discusses the views of 19th and 20th century existentialists Kierkegaard, Nietzsche, Heidegger, and Sartre and interprets the impact of their thinking on literature, art, and philosophy.

This paper examines the impact of TikTok on the public's understanding and engagement with psychiatric and psychological concepts. The rise of mental health-related content on social media has been linked to an increase in adults seeking a diagnosis of ADHD (Yeung et al., 2022). By reviewing a case study: the revision of the term "object permanence" from a developmental stage to an attention-deficit/hyperactivity disorder symptom, I argue that a looping effect, modeled after Hacking (1999), can explain the pattern of language (...) revision for psychological terms on TikTok. Interviews with TikTok users provide preliminary evidence for this looping effect and the research is contextualized within the broader psychiatric discourse. (shrink)

In this chapter, it is argued that the Mind-Body Powers model of neural correlates of consciousness provides a metaphysical framework that yields the theoretical possibility of empirically detecting consciousness. Since the model is informed by an Aristotelian-Thomistic hylomorphic ontology rather than a physicalist ontology, it provides a philosophical foundation for the science of consciousness that is an alternative to physicalism. Our claim is not that the Mind-Body Powers model provides the only alternative, but rather that it provides a sufficient framework (...) for empirically detecting and scientifically studying consciousness. Elsewhere, the integrated information theory’s prediction about the neural correlate of being conscious has been used to illustrate how the Mind-Body Powers model grounds the possibility of empirically detecting consciousness (see M. Owen, 2021, ch. 8). The theory’s prediction was used as one plausible example of a hypothesis about the nature and location of the neural correlate that can be combined with the model. However, there is no settled conclusion about which neurobiological theory of consciousness accurately identifies the neural mechanisms corresponding to being conscious (NAS, 2021, p. 39; Sattin et al., 2021; Seth, 2017; Seth & Bayne, 2022). Therefore, this work will employ another plausible neurobiological prediction provided by the Temporal Circuit Hypothesis. The hypothesis is combined with the Mind-Body Powers model to demonstrate that empirically detecting consciousness is metaphysically plausible wholly apart from a physicalist framework. (shrink)

_Kant’s Reason_ (2023) is an excellent study that develops an original set of interpretive claims and shows their relevance for contemporary theories of rationality. At the core of Karl Schafer’s project is the following thesis: that Kant’s account of reason is unified as a power of comprehension in both its theoretical and practical activities. The aim of my paper is to examine this thesis against Kant’s doctrine of the Highest Good. In §1, I question some claims Schafer makes about the (...) Highest Good. Then, in §2 and §3, I consider how we might develop a more detailed reading of this doctrine along the lines of Schafer’s project. §4 concludes. (shrink)

We consider how human subjects establish signaling conventions in the context of Lewis-Skyrms signaling games. These experiments involve games where there are precisely the right number of signal types to represent the states of nature, games where there are more signal types than states, and games where there are fewer signal types than states. The aim is to determine the conditions under which subjects are able to establish signaling conventions in such games and to identify a learning dynamics that approximates (...) how they succeed when they do. Our results suggest that human agents tend to use a win-stay/lose-shift with inertia dynamics to establish conventions in such games. We briefly consider the virtues and vices of this low-rationality dynamics. (shrink)

To investigate possible cognitive factors influencing the cross-cultural incidence of spirit possession concepts and to develop a more refined understanding of the precise contours of 'intuitive mind-body dualism', two studies were conducted that explored adults' intuitions about the relationship between minds and bodies. Specifically, the studies explored how participants reason about the effects of a hypothetical mind-migration across a range of behaviours. Both studies used hypothetical mind-transfer scenarios in which the mind of one person is transferred into the body of (...) another person. Participants were asked to reason about the new post-transfer person's behaviours and aptitudes. In Study 1, participants were provided with a scale on which they indicated their answers; in Study 2, participants responded to open-ended questions. In both studies, the majority of participants reasoned that while the post-transfer person's performance on physical tasks would be similar to the host performance on mental tasks would be similar to the person whose mind has been transferred. Further, participants tended to assume a complete displacement of minds, such that the post-transfer person's performance on mental task items was reasoned to be identical to incoming person's performance normally. The relevance of these findings for explaining the variable incidence and spread of different possession concepts is discussed. (shrink)

In this paper I describe the history of the surreal trajectories problem and argue that in fact it is not a problem for Bohm's theory. More specifically, I argue that one can take the particle trajectories predicted by Bohm's theory to be the actual trajectories that particles follow and that there is no reason to suppose that good particle detectors are somehow fooled in the context of the surreal trajectories experiments. Rather than showing that Bohm's theory predicts the wrong particle (...) trajectories or that it somehow prevents one from making reliable measurements, such experiments ultimately reveal the special role played by position and the fundamental incompatibility between Bohm's theory and relativity. They also provide a striking example of the theory-ladenness of observation. (shrink)

This chapter examines the place of India in eighteenth-century debates over the chronology of human history. It begins with Voltaire, who strategically praised ancient Brahmanic religion for upholding a pure form of monotheism and an equally pure form of morality. Voltaire’s aim was to upset the primacy assigned to the Mosaic tradition foundational to the Catholic church. The chapter then turns to Herder and his effort to improve upon the historical methods of Voltaire. While Herder is often considered to have (...) developed positive views toward ancient Indian culture, the chapter shows that his commitment to a biblical chronology was consistent throughout his career.

Discussions of what minds are and what they do is a contentious issue. This is particularly so when considering non‐human animals, for here the questions become: do they have minds at all? And if so, what kinds of minds are they? Alternatives to Cartesian or computational models of mind open up a whole new space of possibility for how we should conceive of animal minds, while also highlighting how Skinner's pragmatist‐inspired radical behaviourism has much more to offer than most researchers (...) in animal cognition would like to admit. Pragmatism, or ‘American Naturalism' is also highlighted by Chemero as the alternative for human cognition. The challenge, then, is to build an understanding of mind along pragmatist lines in a way that does justice to both human and non‐human animals. A clear understanding of embodiment, and commitment to a radical form of enactivism, can, perhaps, begin to generate a better kind of continuity. (shrink)

There is a long tradition of trying to find a satisfactory interpretation of Everett's relative-state formulation of quantum mechanics. Albert and Loewer recently described two new ways of reading Everett: one we will call the single-mind theory and the other the many-minds theory. I will briefly describe these theories and present some of their merits and problems. Since both are no-collapse theories, a significant merit is that they can take advantage of certain properties of the linear dynamics, which Everett apparently (...) considered to be important, to constrain their statistical laws.

Because of the conceptual difficulties it faces, quantum mechanics provides a salient example of how alternative metaphysical commitments may clarify our understanding of a physical theory and the explanations it provides. Here we will consider how postulating alternative quantum worlds in the context of Hugh Everett III’s pure wave mechanics may serve to explain determinate measurement records and the standard quantum statistics. We will focus on the properties of such worlds, then briefly consider other metaphysical options available for interpreting pure (...) wave mechanics. These reflections will serve to illustrate both the nature and the limits of naturalized metaphysics. (shrink)

argued that there are two options for what he called a realistic solution to the quantum measurement problem: (1) select a preferred set of observables for which definite values are assumed to exist, or (2) attempt to assign definite values to all observables simultaneously (1810–1). While conventional wisdom has it that the second option is ruled out by the Kochen-Specker theorem, Vink nevertheless advocated it. Making every physical quantity determinate in quantum mechanics carries with it significant conceptual costs, but it (...) also provides a way of addressing the preferred basis problem that arises if one chooses to pursue the first option. The potential costs and benefits of a formulation of quantum mechanics where every physical quantity is determinate are herein examined.

Given the ever-present subject of consciousness wherever consciousness is, it is peculiar that consciousness researchers often mention mental states as if they are conscious independently of being the conscious states of someone [1, p. 132]. We refer to visual perceptions that become conscious, when in reality no one has ever studied mere conscious visual perceptions. What are studied are visual perceptions belonging to conscious human or animal subjects; it is the subjects who are conscious of visual stimuli, not the visual (...) perceptions. I do not know all the reasons why conscious subjects are rarely mentioned in consciousness science, but one could be pragmatic. Explaining the mysterious jump from the nonconscious nuts and bolts of neurons to the aurora borealis of consciousness is a hard problem. But it is an easy problem compared to explaining the emergence of a single conscious subject from the human brain’s 86 billion neurons [cf. 5]. Perhaps it is more practically realistic to solve the less hard problem before attempting to solve the harder hard problem. On the other hand, if we ignore a necessary condition for the presence of consciousness, our explanations of it could be plagued by inadequacy. And how can we explain our whole data set regarding consciousness if we neglect the most fundamental aspect of the data? (shrink)

The idea that the changing entropy of a system is relevant to explaining why we know more about the system's past than about its future has been criticized on several fronts. This paper assesses the criticisms and clarifies the epistemology of the inference problem. It deploys a Markov process model to investigate the relationship between entropy and temporally asymmetric inference.

Grievance landscapes form in rapidly industrialising contexts where social and environmental impacts are inevitable. This paper focuses on the complex operational and organisational settings in which grievances arise and the industrial pathologies that form around resource development projects. The arguments draw on classic and contemporary literature on “grievance”, “right” and “entitlement”, and the authors’ own sustained engagement with global mining companies and local communities. Our contention is that the grievance landscape is far more critical to understanding environmental, human rights, and (...) mining interactions than the managerial systems that companies construct to signal compliance with voluntary international norms. These managerial systems, or operational-level grievance mechanisms, map the procedural contours of how a local grievance would travel once it is made visible to the company. In practice, however, it is fiction, illegibility and invisibility that dominate. Across the pathologies, the common denominator is the corporate propensity to avoid recognising the legitimacy of a local grievance and the source of its cause. (shrink)

This paper is concerned with the possibility and nature of relativistic hidden-variable formulations of quantum mechanics. Both ad hoc teleological constructions of spacetime maps and frame-dependent constructions of spacetime maps are considered. While frame-dependent constructions are clearly preferable, they provide neither mechanical nor causal explanations for local quantum events. Rather, the hiddenvariable dynamics used in such constructions is just a rule that helps to characterize the set of all possible spacetime maps. But while having neither mechanical nor causal explanations of (...) the values of quantummechanical measurement records is a significant cost, it may simply prove too much to ask for such explanations in relativistic quantum mechanics.

On Bohm''s formulation of quantum mechanics particles always have determinate positions and follow continuous trajectories. Bohm''s theory, however, requires a postulate that says that particles are initially distributed in a special way: particles are randomly distributed so that the probability of their positions being represented by a point in any regionR in configuration space is equal to the square of the wave-function integrated overR. If the distribution postulate were false, then the theory would generally fail to make the right statistical (...) predictions. Further, if it were false, then there would at least in principle be situations where a particle would approach an eigenstate of having one position but in fact always be somewhere very different. Indeed, we will see how this might happen even if the distribution postulate were true. This will help to show how loose the connection is between the wave-function and the positions of particles in Bohm''s theory and what the precise role of the distribution postulate is. Finally, we will briefly consider two attempts to formulate a version of Bohm''s theory without the distribution postulate. (shrink)

Certainty has proved to be a troublesome epistemological concept, which motivates many philosophers to be fallibilists. But fallibilism proves troublesome, too, as it is hard to state in a way that does not either imply skepticism, or deny that there are necessary truths. The Sellarsian idea of a space of reasons in which there are normative proprieties attached to epistemic positions allows for an understanding of fallibilism which allows that there is knowledge, there are necessary truths, and yet we can (...) be wrong about anything. This result is accomplished by taking the fallibilist claim as a normative recommendation, not a descriptive thesis. (shrink)

Everett proposed resolving the quantum measurement problem by dropping the nonlinear collapse dynamics from quantum mechanics and taking what is left as a complete physical theory. If one takes such a proposal seriously, then the question becomes how much of the predictive and explanatory power of the standard theory can one recover without the collapse postulate and without adding anything else. Quantum mechanics without the collapse postulate has several suggestive properties, which we will consider in some detail. While these properties (...) are not enough to make it acceptable given the usual standards for a satisfactory physical theory, one might want to exploit these properties to cook up a satisfactory no-collapse formulation of quantum mechanics. In considering how this might work, we will see why any no-collapse theory must generally fail to satisfy at least one of two plausible-sounding conditions. (shrink)

Skyrms-Lewis sender-receiver games with invention allow one to model how a simple mathematical language might be invented and become meaningful as its use coevolves with the basic arithmetic competence of primitive mathematical inquirers. Such models provide sufficient conditions for the invention and evolution of a very basic sort of arithmetic language and practice, and, in doing so, provide insight into the nature of a correspondingly basic sort of mathematical knowledge in an evolutionary context. Given traditional philosophical reflections concerning the nature (...) and preconditions of mathematical knowledge, these conditions are strikingly modest. (shrink)
