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.

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.

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)

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)

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)

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.

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)

Everett's relative-state formulation of quantum mechanics is an attempt to solve the measurement problem by dropping the collapse dynamics from the standard von Neumann-Dirac theory of quantum mechanics. The main problem with Everett's theory is that it is not at all clear how it is supposed to work. In particular, while it is clear that he wanted to explain why we get determinate measurement results in the context of his theory, it is unclear how he intended to do this. There (...) have been many attempts to reconstruct Everett's no-collapse theory in order to account for the apparent determinateness of measurement outcomes. These attempts have led to such formulations of quantum mechanics as the many-worlds, many-minds, many-histories, and relative-fact theories. Each of these captures part of what Everett claimed for his theory, but each also encounters problems. (shrink)

A leading contemporary theory of consciousness in theoretical neuroscience apparently shares significant common ground with a philosophical system of thought from Antiquity. Although chronologically disparate, the integrated information theory of consciousness and Aristotelian metaphysics seem to be akin with regards to fundamental ontology, epistemic priority, and causal powers. In this article, I explore these areas of common ground. Additionally, I consider an apparent dissimilarity regarding panpsychism and suggest that an Aristotelian understanding of powers provides a natural way for IIT to (...) reasonably regulate its ascription of consciousness.

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)

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)

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)

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)

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)

Although Penn et al's incisive critique of comparative cognition is welcomed, their heavily computational and representational account of cognition commits them to a purely internalist view of cognitive processes. This perhaps blinds them to a distributed alternative that raises the possibility that the human cognitive revolution occurred outside the head, and not in it.

Joanna Leidenhag’s research monograph Minding Creation: Theological Panpsychism and the Doctrine of Creation argues that theologians should seriously consider and perhaps even support panpsychism. In light of rekindled interest in panpsychism amongst philosophers of mind and a noteworthy minority of cognitive neuroscientists, which comes in the wake of physicalism’s faltering, Leidenhag’s thesis is timely. This work briefly analyzes some key aspects of Minding Creation.

Within the context of general relativity, the Heraclitus asymmetry property requires that no distinct pair of spacetime events have the same local structure Manchak and Barrett (2023). Here, we explore Heraclitus-maximal worlds – those which are “as large as they can be” with respect to the Heraclitus property. Using Zorn’s lemma, we prove that such worlds exist and highlight a number of their properties. If attention is restricted to Heraclitus-maximal worlds, we show senses in which observers have the epistemic (...) resources to know which world they inhabit. (shrink)

Ontological monists hold that there is only one way of being, while ontological pluralists hold that there are many; for example, concrete objects like tables and chairs exist in a different way from abstract objects like numbers and sets. Correspondingly, the monist will want the familiar existential quantifier as a primitive logical constant, whereas the pluralist will want distinct ones, such as for abstract and concrete existence. In this paper, we consider how the debate between the monist and pluralist relates (...) to the standard test for logicality. We deploy this test and show that it favors the monist. (shrink)

These lines, presented as they appear in the O.C.T., are among the most difficult and hotly disputed that Juvenal wrote. The poet defends his decision not to attack contemporary politicians directly: ‘expose a Tigellinus’, he says, ‘and you know what the consequences will be’. It has long been recognized that the consequences related are probably inspired by those suffered by the Christians in A.D. 64 during the reign of Nero, and so vividly described by Tacitus.

In lieu of an abstract, here is a brief excerpt of the content:76 AN UNNOTICED ERROR IN HUME'S TREATISE "...the conformity between love and hatred in the agreeableness of their sensation makes them always be excited by the same objects..." Treatise, Book II, Part II, Sec. X. This passage from Hume's A Treatise of Human Nature is taken from the first edition of 1739. It can also be found in the Everyman Edition, the editions of Selby-Bigge Mossner, and Green and (...) Grosse, without editorial comment of any kind. Yet it contains a glaring and obvious error. The most superficial reading of Book II will convince one that it is love and pride that conform in the agreeableness of their sensation they are both indirect passions that aire pleasant in feeling. On the other hand, humility and hatred share in being disagree able or unpleasant impressions. This might have been a printer's error, or Hume's own mistake, and the reason for it is not hard to find. This part of Book II was called "Of love and hatred" ; the expression "love and hatred" recurs several times throughout the whole. In ei»ther the writing of the manuscript or the type setting of the text, a habit was established. Habit, which Hume himself used to explain so much else, must here be cited as the explanation of this slip. What is more interesting is the reason why such an obvious error has gone so long unnoticed. Here an ambiguity in Hume's use of the word "object" should be noticed. It is sometimes used simply as a synonym for "thing" and this is the usage in "excited by the same objects". Hume is merely saying that love and pride have the same sorts of cause. When this cause is found in oneself it leads to pride and when in another it leads to love. This of course is connected with the fact that both these passions are aggreeable or pleasant in sensation. 77 "Object" also has a special technical use in Book II when it refers to the person towards whom the passion is directed, as in "the object of the passion". Now love and hatred do have a similar sort of object, i.e. another person, whereas the object of pride and humility is, according to Hume, always oneself. In this usage, the object of a passion is carefully distinguished by Hume from its cause. It is possible that a careless and superficial reading of this passage might lead one to think that Hume meant to say that love and hatred agree in having the same sort of object, i.e. another person. Such inattention is to be deplored, but after all, until very recently, such inattention was typical of the attitude of philosophers towards Book II 2 as a whole. D. W. D. Owen University of Stirling 1.See for instance the previous paragraph; "I have suppos'd all along, that the passions of love and pride, and those of humility and hatred are similar in their sensations, and that the two former are always agreeable, and the two latter painful." 2.Thanks are due to Mr. Roland Hall for checking the first edition on my behalf....
