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.

This book explores Hume's account of reason and its role in human understanding, seen in the context of other notable accounts by philosophers of the early modern period. David Owen offers new interpretations of many of Hume's most famous arguments about induction, belief, scepticism, the passions, and moral distinctions.

The Shape of Thought: How Mental Adaptations Evolve presents a road map for an evolutionary psychology of the twenty-first century. It brings together theory from biology and cognitive science to show how the brain can be composed of specialized adaptations, and yet also an organ of plasticity. Although mental adaptations have typically been seen as monolithic, hard-wired components frozen in the evolutionary past, The Shape of Thought presents a new view of mental adaptations as diverse and variable, with distinct functions (...) and evolutionary histories that shape how they develop, what information they use, and what they do with that information. The book describes how advances in evolutionary developmental biology can be applied to the brain by focusing on the design of the developmental systems that build it. Crucially, developmental systems can be plastic, designed by the process of natural selection to build adaptive phenotypes using the rich information available in our social and physical environments. This approach bridges the long-standing divide between "nativist" approaches to development, based on innateness, and "empiricist" approaches, based on learning. It shows how a view of humans as a flexible, culturally-dependent species is compatible with a complexly specialized brain, and how the nature of our flexibility can be better understood by confronting the evolved design of the organ on which that flexibility depends.

Kant is well known for claiming that we can never really know our true moral disposition. He is less well known for claiming that the injunction "Know Yourself" is the basis of all self-regarding duties. Taken together, these two claims seem contradictory. My aim in this paper is to show how they can be reconciled. I first address the question of whether the duty of self-knowledge is logically coherent (§1). I then examine some of the practical problems surrounding the duty, (...) notably, self-deception (§2). Finding none of Kant's solutions to the problem of self-deception satisfactory, I conclude by defending a Kantian account of self-knowledge based on his theory of conscience (§3). (shrink)

Todd Moody’s Zombie Earth thought experiment is an attempt to show that ‘conscious inessentialism’ is false or in need of qualification. We defend conscious inessentialism against his criticisms, and argue that zombie thought experiments highlight the need to explain why consciousness evolved and what function(s) it serves. This is the hardest problem in consciousness studies.

In Measuring the Immeasurable Mind: Where Contemporary Neuroscience Meets the Aristotelian Tradition, Matthew Owen argues that despite its nonphysical character, it is possible to empirically detect and measure consciousness. -/- Toward the end of the previous century, the neuroscience of consciousness set its roots and sprouted within a materialist milieu that reduced the mind to matter. Several decades later, dualism is being dusted off and reconsidered. Although some may see this revival as a threat to consciousness science aimed at (...) measuring the conscious mind, Owen argues that measuring consciousness, along with the medical benefits of such measurements, is not ruled out by consciousness being nonphysical. Owen proposes the Mind-Body Powers model of neural correlates of consciousness, which is informed by Aristotelian causation and a substance dualist view of human nature inspired by Thomas Aquinas, who often followed Aristotle. In addition to explaining why there are neural correlates of consciousness, the model provides a philosophical foundation for empirically discerning and quantifying consciousness. En route to presenting and applying the Mind-Body Powers model to neurobiology, Owen rebuts longstanding objections to dualism related to the mind-body problem. With scholarly precision and readable clarity, Owen applies an oft forgotten yet richly developed historical vantage point to contemporary cognitive neuroscience. (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)

Maturity and Modernity examines Nietzsche, Weber and Foucault as a distinct trajectory of critical thinking within modern thought which traces the emergence and development of genealogy in the form of imminent critique. David Owen clarifies the relationship between these thinkers and responds to Habermas' (and Dews') charge that these thinkers are nihilists and that their approach is philosophically incoherent and practically irresponsible by showing how genealogy as a practical activity is directed toward the achievements of human autonomy. The scope (...) of the book covers the critical methodologies developed by these thinkers with respect to the analysis of how we have become what we are and the implication which they draw for the possibility of human autonomy in the present. It proceeds by detailed analysis of each thinker in turn showing the structure of their approach, their historical account of the emergence of modernity, and the politics of their attempts to facilitate the achievement of human autonomy.

I examine several alleged grounds of the principle of sufficient reason in Leibniz’s philosophy. These include the nature of a requisite and a sufficient condition, the nature of truth, and the nature of harmony. I argue that Leibniz does not ground the PSR in any of these ways. Instead, he is committed to a value-based grounds of the PSR: God creates the best possible world, and the fact that the PSR obtains in this world contributes to it being the best. (...) I conclude by considering some objections to this way of grounding the PSR. (shrink)

Hume’s celebrated argument concerning miracles, and an 18th century criticism of it put forward by Richard Price, is here interpreted in terms of the modern controversy over the base-rate fallacy. When considering to what degree we should trust a witness, should we or should we not take into account the prior probability of the event reported? The reliability of the witness (’Pr’(says e/e)) is distinguished from the credibility of the testimony (’Pr’(e/says e)), and it is argued that Hume, as a (...) good proto-Bayesian, argued that the credibility of the testimony should be calculated in terms of both the reliability of the witness and the prior probability of the event reported.

Kant's remark may sound harsh to our modern sensibility but it raises an issue that is central to an understanding of Nietzsche's critique of "the democratic movement of our times" (BGE 203) and, thus, to an understanding of Nietzsche's salience for contemporary democratic theory. This issue is self-respect—and, more generally, the topic of duties to oneself. The relationship between this issue and democratic theory may not appear a wholly obvious one but, on Nietzsche's account, it is crucial to the kind (...) of equality that is expressed by democratic practices. Nietzsche's concern, I'll argue, is that "the democratic movement of our times" expresses a levelling mode of equality that undermines the conditions of self-respect in the relevant sense. Consequently, the aim of this article will be to elucidate Nietzsche's understanding of self-respect, to clarify the grounds on which he attacks "the democratic movement of our times" and to consider the relationship between these arguments and his advocacy of the agon as a model of cultural and political relations. It concludes by drawing out the implications of this interpretation of Nietzsche for democratic theory. (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)

This article addresses three questions about well-being. First, is well-being future-sensitive? I.e., can present well-being depend on future events? Second, is well-being recursively dependent? I.e., can present well-being depend on itself? Third, can present and future well-being be interdependent? The third question combines the first two, in the sense that a yes to it is equivalent to yeses to both the first and second. To do justice to the diverse ways we contemplate well-being, I consider our thought and discourse about (...) well-being in three domains: everyday conversation, social science, and philosophy. This article’s main conclusion is that we must answer the third question with no. Present and future well-being cannot be interdependent. The reason, in short, is that a theory of well-being that countenances both future-sensitivity and recursive dependence would have us understand a person’s well-being at a time as so intricately tied to her well-being at other times that it would not make sense to consider her well-being an aspect of her state at particular times. It follows that we must reject either future-sensitivity or recursive dependence. I ultimately suggest, especially in light of arguments based on assumptions of empirical research on well-being, that the balance of reasons favors rejecting future-sensitivity. (shrink)

We are engineers, and our view of consciousness is shaped by an engineering ambition: we would like to build a conscious machine. We begin by acknowledging that we may be a little disadvantaged, in that consciousness studies do not form part of the engineering curriculum, and so we may be starting from a position of considerable ignorance as regards the study of consciousness itself. In practice, however, this may not set us back very far; almost a decade ago, Crick wrote: (...) 'Everyone has a rough idea of what is meant by consciousness. It is better to avoid a precise definition of consciousness because of the dangers of premature definition. Until the problem is understood much better, any attempt at a formal definition is likely to be either misleading or overly restrictive, or both'. This seems to be as true now as it was then, although the identification of different aspects of consciousness by Block has certainly brought a degree of clarification. On the other hand, there is little doubt that consciousness does seem to be something to do with the operation of a sophisticated control system, and we can claim more familiarity with control systems than can most philosophers, so perhaps we can make up some ground there.

The success of digital COVID-19 contact tracing requires a strategy that successfully addresses the digital divide—inequitable access to technology such as smartphones. Lack of access both undermines the degree of social benefit achieved by the use of tracing apps, and exacerbates existing social and health inequities because those who lack access are likely to already be disadvantaged. Recently, Singapore has introduced portable tracing wearables (with the same functionality as a contact tracing app) to address the equity gap and promote public (...) health. We argue that governments have an ethical obligation to ensure fair access to the protective benefits of contract tracing during the pandemic and that wearables are an effective way of addressing some important equity issues. The most contentious issues about contact tracing apps have been the potential infringements of privacy and individual liberty, especially where the use of apps or other technology (such as wearables or QR codes) is required for access to certain spaces. Here we argue that wearables, as opposed to apps alone, will make a digital contact tracing mandate more practical and explain some conditions under which such a mandate would be justified. We focus on Singapore as a case study that has recently deployed contact tracing wearables nationally, but also reference debate about wearables in Australia and New Zealand. Our analysis will be relevant to counties trialling similar portable tracing wearables. (shrink)

Consciousness and evolution are complex phenomena. It is sometimes thought that if adaptation explanations for some varieties of consciousness, say, conscious visual perception, can be had, then we may be reassured that at least those kinds of consciousness are not epiphenomena. But what if other varieties of consciousness, for example, dreams, are not adaptations? We sort out the connections among evolution, adaptation, and epiphenomenalism in order to show that the consequences for the nature and causal efficacy of consciousness are not (...) as dire as has sometimes been supposed.

This book takes a theoretical enterprise in Christian philosophy of religion and applies it to Buddhism, thus defending Buddhism and presenting it favorably in comparison. Chapters explore how the claims of both Christianity and Theravada Buddhism rest on people's experiences, so the question as to which claimants to religious knowledge are right rests on the evidential value of those experiences. The book examines mysticism and ways to understand what goes on in religious experiences, helping us to understand whether it is (...) good grounds for religious belief. The author argues that religious language in both Christian and Buddhist traditions is intelligible as factual discourse, and so reports of mystical experience are true or false. The book contends that those experiences can be fruitfully thought of as perceptual in kind and that they are therefore good prima facie grounds for religious belief, in the absence of defeating conditions. The work goes on to explore Christian and Buddhist testimony and how the likelihood of self-deception, self-delusion, imaginative elaboration and the like constitutes a defeating condition. It is shown that this defeater has less scope for operation in the Buddhist case than in the Christian case, and therefore Theravada Buddhism is better grounded. This work will appeal to students and scholars of philosophy and philosophy of religion, and those interested in the study of religious experience. (shrink)

‘ANY state of mind in which anyone takes a great interest is very likely to be called “knowledge”, because no other word in psychology has such emotive virtue’, wrote Ogden and Richards apropos of those who claim that art affords us a kind of knowledge uniquely its own. While one may agree with the implications of this remark, and it is a salutary warning to anyone tempted to make extravagant claims for art, it does less than justice to the intentions (...) of those who make these claims. They are at least facing up to a real problem—a problem which has troubled philosophers since the time of Plato. For, beyond doubt, the arts have been held in high regard in every society with a well developed culture. To dismiss art as mere entertainment or pleasant deception or fantasy gratification or play only raises the question why intelligent and educated people take such trivial stuff seriously, why they consider it important and often find it profound. One way of meeting this problem is to say that art gives us a special kind of knowledge or insight which other branches of human learning—history, science and even philosophy—do not and cannot give us. This may not be a solution to the problem, but it is a view that deserves to be taken seriously, and I propose in this article to consider one aspect of it. (shrink)
