It is argued that Weyl’s theory of gravitation and electricity came out of ‘mathematical justice’: out of the equal rights direction and length. Such mathematical justice was manifestly at work in the context of discovery, and is enough to derive all of source-free electromagnetism. Weyl’s repeated references to coordinates and gauge are taken to express equal treatment of direction and length.

The standard $\mathbb{U}(1)$ “gauge principle” or “gauge argument” produces an exact potential A=dλ and a vanishing field F=d 2 λ=0. Weyl (in Z. Phys. 56:330–352, 1929; Rice Inst. Pam. 16:280–295, 1929) has his own gauge argument, which is sketchy, archaic and hard to follow; but at least it produces an inexact potential A and a nonvanishing field F=dA≠0. I attempt a reconstruction.

The determination of inertia by matter is looked at in general relativity, where inertia can be represented by affine or projective structure. The matter tensor T seems to underdetermine affine structure by ten degrees of freedom, eight of which can be eliminated by gauge choices, leaving two. Their physical meaning---which is bound up with that of gravitational waves and the pseudotensor t, and with the conservation of energy-momentum---is considered, along with the dependence of reality on invariance and of causal explanation (...) on conservation.

For a novice this book is a mathematically-oriented introduction to modal logic, the discipline within mathematical logic studying mathematical models of reasoning which involve various kinds of modal operators. It starts with very fundamental concepts and gradually proceeds to the front line of current research, introducing in full details the modern semantic and algebraic apparatus and covering practically all classical results in the field. It contains both numerous exercises and open problems, and presupposes only minimal knowledge in mathematics. A specialist (...) can use the book as a source of references. Results and methods of many directions in propositional modal logic, from completeness and duality to algorithmic problems, are collected and systematically presented in one volume. (shrink)

This new edition of Alexander Miller’s highly readable introduction to contemporary metaethics provides a critical overview of the main arguments and themes in twentieth- and twenty-first-century contemporary metaethics. Miller traces the development of contemporary debates in metaethics from their beginnings in the work of G. E. Moore up to the most recent arguments between naturalism and non-naturalism, cognitivism and non-cognitivism. From Moore’s attack on ethical naturalism, A. J. Ayer’s emotivism and Simon Blackburn’s quasi-realism to anti-realist and best opinion accounts (...) of moral truth and the non-reductionist naturalism of the ‘Cornell realists’, this book addresses all the key theories and ideas in this field. As well as revisiting the whole terrain with revised and updated guides to further reading, Miller also introduces major new sections on the revolutionary fictionalism of Richard Joyce and the hermeneutic fictionalism of Mark Kalderon. The new edition will continue to be essential reading for students, teachers and professional philosophers with an interest in contemporary metaethics. (shrink)

Nicholas Dixon’s Kantian argument for why mixed martial arts (MMA) is intrinsically immoral has received several critical responses. We offer an additional critical response. Unlike previous responses, ours does not rely on an interpretation of the categorical imperative that Dixon would find tendentious. Instead, we grant that Dixon’s views about what makes other sports consistent with the categorical imperative are correct and argue from this assumption that MMA is also consistent with the categorical imperative. Our argument focuses on Dixon’s claims (...) about certain cycling tactics, which we call ‘pain-leveraging cycling tactics’. We argue that MMA is consistent with the categorical imperative for the same sort of reasons that Dixon claims make pain-leveraging cycling tactics consistent with the categorical imperative.

In this paper, we argue that a distinction ought to be drawn between two ways in which a given world might be logically impossible. First, a world w might be impossible because the laws that hold at w are different from those that hold at some other world (say the actual world). Second, a world w might be impossible because the laws of logic that hold in some world (say the actual world) are violated at w. We develop a novel (...) way of modelling logical possibility that makes room for both kinds of logical impossibility. Doing so has interesting implications for the relationship between logical possibility and other kinds of possibility (for example, metaphysical possibility) and implications for the necessity or contingency of the laws of logic.

Toby Svoboda (2011, 2015) argues that humans cannot ever justifiably attribute intrinsic value to nature because we can never have evidence that any part of non-human nature has intrinsic value. We argue that, at best, Svoboda's position leaves us with uncertainty about whether there is intrinsic value in the non-human natural world. This uncertainty, however, together with reason to believe that at least some non-human natural entities would possess intrinsic value if anything does, leaves us in a position to acquire (...) evidence that non-human nature has intrinsic value. We appeal to Michael Huemer's (2013) Probabilistic Reasons Principle to argue that we have direct reasons to not act in ways destructive to non-human nature, even if this reason is defeasible. Hence, if having intrinsic value just is being a source of direct reasons, it also implies that non-human nature has intrinsic value. (shrink)

In this paper the concept of supervenience is employed to explain the relationship between fitness as employed in the theory of natural selection and population biology and the physical, behavioral and ecological properties of organisms that are the subjects of lower level theories in the life sciences. The aim of this analysis is to account simultaneously for the fact that the theory of natural selection is a synthetic body of empirical claims, and for the fact that it continues to be (...) misconstrued, even by biologists, for a tautological system. The notion of supervenience is then employed to provide a new statement of the relation of Mendelian predicates to molecular ones in order to provide for the commensurability and potential reducibility of Mendelian to molecular genetics in a way that circumvents the theoretical complications which appear to stand in the way of such a reduction.

Regularity is the thesis that all contingent propositions should be assigned probabilities strictly between zero and one. I will prove on cardinality grounds that if the domain is large enough, a regular probability assignment is impossible, even if we expand the range of values that probabilities can take, including, for instance, hyperreal values, and significantly weaken the axioms of probability.

The rule-following debate, in its concern with the metaphysics and epistemology of linguistic meaning and mental content, goes to the heart of the most fundamental questions of contemporary philosophy of mind and language. This volume gathers together the most important contributions to the topic, including papers by Simon Blackburn, Paul Boghossian, Graeme Forbes, Warren Goldfarb, Paul Horwich, John McDowell, Colin McGinn, Ruth Millikan, Philip Pettit, George Wilson, and José Zalabardo. This debate has centred on Saul Kripke's reading of the rule-following (...) sections in Wittgenstein and his consequent posing of a "sceptical paradox" that threatens our every day notions of linguistic meaning and mental content. These essays are attempts to respond to this challenge and represent some of the most important work in contemporary theory of meaning. They examine the notion of meaning; whether it is possible to find a suitable meaning-constituting fact from our previous behaviour or mental histories; objections to, and defenses of, dispositional accounts of meaning; the plausibility of non-factualism about meaning; our attempts to develop non-reductionist accounts of meaning; and the sources of the normativity which attaches to meaning, such as the linguistic practice of the community or the dispositions of the individual. With an introductory essay and a comprehensive guide to further reading the book is an excellent resource for courses in philosophy of mind, philosophy of language, Wittgenstein, and metaphysics, as well as for all philosophers, linguists, and cognitive scientists with interests in these areas. Contributors include Simon Blackburn, Paul Boghossian, Graeme Forbes, Warren Goldfarb, Paul Horwich, John McDowell, Colin McGinn, Alexander Miller, Ruth Garrett Millikan, Philip Pettit, George. M. Wilson, Crispin Wright, and José L. Zalabardo. (shrink)

One powerful argument for dualism is provided by Chalmers: the ‘zombie’ or conceivability argument. This paper aims to establish that if one adopts the ‘Powerful Qualities’ account of properties developed by Martin and Heil, this argument can be resisted at the first premise: the claim that zombies are conceivable is, by the lights of Chalmers’ own account of conceivability, false. The Powerful Qualities account is outlined. Chalmers’ argument, and several distinctions which underlie it, are explained. It is argued that to (...) make sense of the claim that zombies are conceivable, some account of properties must be given. The paper’s central claim is presented and defended from potential responses: given the Powerful Qualities view, zombies are in fact inconceivable. Finally, an error theory is presented, which offers an explanation of why so many have taken the conceivability of zombies to be unproblematic, and the view is briefly contrasted with Russellian monism.

The diversity, complexity and adaptation of the biological realm is evident. Until Darwin, the best explanation for these three features of the biological was the conclusion of the “argument from design.” Darwin's theory of natural selection provides an explanation of all three of these features of the biological realm without adverting to some mysterious designing entity. But this explanation's success turns on the meaning of its central explanatory concept, ‘fitness’. Moreover, since Darwinian theory provides the resources for a purely causal (...) account of teleology, wherever it is manifested, its reliance on the concept of ‘fitness’ makes it imperative that conceptual problems threatening the explanatory legitimacy of this notion be solved.

One of the problems that Bayesian regularity, the thesis that all contingent propositions should be given probabilities strictly between zero and one, faces is the possibility of random processes that randomly and uniformly choose a number between zero and one. According to classical probability theory, the probability that such a process picks a particular number in the range is zero, but of course any number in the range can indeed be picked. There is a solution to this particular problem on (...) the books: a measure that assigns the same infinitesimal probability to each number between zero and one. I will show that such a measure, while mathematically interesting, is pathological for use in confirmation theory, for the same reason that a measure that assigns an infinitesimal probability to each possible outcome in a countably infinite lottery is pathological. The pathology is that one can force someone to assign a probability within an infinitesimal of one to an unlikely event. (shrink)

Renormalization group (RG) methods are an established strategy to explain how it is possible that microscopically different systems exhibit virtually the same macro behavior when undergoing phase-transitions. I argue – in agreement with Robert Batterman – that RG explanations are non-causal explanations. However, Batterman misidentifies the reason why RG explanations are non-causal: it is not the case that an explanation is non- causal if it ignores causal details. I propose an alternative argument, according to which RG explanations are non-causal explanations (...) because their explanatory power is due to the application mathematical operations, which do not serve the purpose of representing causal relations.

Brain states, which correlate with specific motor, cognitive, and emotional states, may be monitored with noninvasive techniques such as electroencephalography and magnetoencephalography that measure macroscopic cortical activity manifested as oscillatory network dynamics. These rhythmic cortical signatures provide insight into the neuronal activity used to identify pathological cortical function in numerous neurological and psychiatric conditions. Sensory and transcranial stimulation, entraining the brain with specific brain rhythms, can effectively induce desired brain states correlated with such cortical rhythms. Because brain states have distinct (...) neural correlates, it may be possible to induce a desired brain state by replicating these neural correlates through stimulation. To do so, we propose recording brain waves from a “donor” in a particular brain state using EEG/MEG to extract cortical signatures of the brain state. These cortical signatures would then be inverted and used to entrain the brain of a “recipient” via sensory or transcranial stimulation. We propose that brain states may thus be transferred between people by acquiring an associated cortical signature from a donor, which, following processing, may be applied to a recipient through sensory or transcranial stimulation. This technique may provide a novel and effective neuromodulation approach to the noninvasive, non-pharmacological treatment of a variety of psychiatric and neurological disorders for which current treatments are mostly limited to pharmacotherapeutic interventions.

Non-reductive physicalists have made a number of attempts to provide the relation of supervenience between levels of properties with enough bite to analyze interesting cases without at the same time losing the relation's acceptability for the physicalist. I criticize some of these proposals and suggest an alternative supplementation of the supervenience relation by imposing a requirement of robustness which is motivated by the notion of structural stability familiar from dynamical systems theory. Robust supervenience, I argue, captures what the non-reductive physicalist (...) wants from supervenience; most importantly, it provides a natural background for reconstructing the notion of (diachronic) property emergence in a way acceptable to physicalists.

As the USA contends with another surge in COVID-19 cases, hospitals may soon need to answer the unresolved question of who lives and dies when ventilator demand exceeds supply. Although most triage policies in the USA have seemingly converged on the use of clinical need and benefit as primary criteria for prioritisation, significant differences exist between institutions in how to assign priority to patients with identical medical prognoses: the so-called ‘tie-breaker’ situations. In particular, one’s status as a frontline healthcare worker (...) has been a proposed criterion for prioritisation in the event of a tie. This article outlines two major grounds for reconsidering HCW prioritisation. The first recognises trust as an indispensable element of clinical care and mistrust as a hindrance to any public health strategy against the virus, thus raising concerns about the outward appearance of favouritism. The second considers the ways in which proponents of HCW prioritisation deviate from the very ‘ethics frameworks’ that often preface triage policies and serve to guide resource allocation—a rhetorical strategy that may undermine the very ethical foundations on which triage policies stand. By appealing to trust and consistency, we re-examine existing arguments in favour of HCW prioritisation and provide a more tenable justification for adjudicating on tie-breaker events during crisis standards of care.

We are largely in agreement with the Findlay & Walker model. However, they appear to dismiss the role of covert spatial attention in tasks in which people are free to move their eyes. We argue that an account of the facts about the perceptual span in reading requires a window of attention not centered around the fovea. Moreover, a computational model of reading that we (Reichle et al. 1998) developed gives a good account of eye movement control in reading and (...) would be unable to do so without relying heavily on covert attention.

According to David Lewis's extreme modal realism, every waythat a world could be is a way that some concretely existingphysical world really is. But if the worlds are physicalentities, then there should be a set of all worlds, whereasI show that in fact the collection of all possible worlds is nota set. The latter conclusion remains true even outside of theLewisian framework.

This paper is a survey of results concerning embeddings of intuitionistic propositional logic and its extensions into various classical modal systems.

Laws in the special sciences are usually regarded to be non-universal. A theory of laws in the special sciences faces two challenges. (I) According to Lange's dilemma, laws in the special sciences are either false or trivially true. (II) They have to meet the ?requirement of relevance?, which is a way to require the non-accidentality of special science laws. I argue that both challenges can be met if one distinguishes four dimensions of (non-) universality. The upshot is that I argue (...) for the following explication of special science laws: L is a special science law just if (1) L is a system law, (2) L is quasi-Newtonian, and (3) L is minimally invariant.

To understand the future of informed consent, we should pay attention to two ethical-legal sources in addition to the revised Common Rule. Physicians acting as investigators and patients serving as research subjects bring to that relationship a long history regarding consent to treatment, and everyone dealing with research ethics needs to be aware of the Nuremberg Code and other human-rights documents. These three streams make separate and distinctly different contributions to informed consent doctrine.

Gödel's ontological argument is a formal argument for a being defined in terms of the concept of a positive property. I shall defend several versions of Gödel's argument, using weaker premises than Anderson's (1990) version, and avoiding Oppy's (1996 and 2000) parody refutations.

Constructivism is the idea that we construct our own world rather than it being determined by an outside reality. Its most consistent form, Radical Constructivism (RC), claims that we cannot transcend our experiences. Thus it doesn't make sense to say that our constructions gradually approach the structure of an external reality. The mind is necessarily an epistemological solipsist, in contrast to being an ontological solipsist who maintains that this is all there is, namely a single mind within which the only (...) world exists. RC recognizes the impossibility of the claim that the world does not exist. Yet, RC has the potential to go much further. I claim that RC provides the foundation of a new world-view in which we can overcome hard scientific problems. Thus, the paper is urging us to carry RC further, not just on philosophical grounds, but also into the domain of science. (shrink)

In several places we have argued that ‘fitness’ is a primitive term with respect to the theory of evolution properly understood. These arguments have relied heavily on the axiomatization of the theory provided by one of us. In contrast, both John Beatty and Robert Brandon have separately argued for a “propensity“ interpretation of “fitness” ; and in Brandon and Beatty they attack our view that “fitness“ is a primitive term in evolutionary theory, concluding that a definition by way of propensities (...) is possible and preferable. Here we reply to their criticisms, and argue that, at most, the view that fitness is a statistical propensity is a terminological variant on our thesis that it is a primitive in evolutionary theory.

_Laruelle_ is one of the first books in English to undertake in an extended critical survey of the work of the idiosyncratic French thinker François Laruelle, the promulgator of non-standard philosophy. Laruelle, who was born in 1937, has recently gained widespread recognition, and Alexander R. Galloway suggests that readers may benefit from colliding Laruelle’s concept of the One with its binary counterpart, the Zero, to explore more fully the relationship between philosophy and the digital. In _Laruelle_, Galloway argues that (...) the digital is a philosophical concept and not simply a technical one, employing a detailed analysis of Laruelle to build this case while referencing other thinkers in the French and Continental traditions, including Alain Badiou, Gilles Deleuze, Martin Heidegger, and Immanuel Kant. In order to explain clearly Laruelle’s concepts such as the philosophical decision and the principle of sufficient philosophy, Galloway lays a broad foundation with his discussions of “the One” as it has developed in continental philosophy, the standard model of philosophy, and how philosophers view “the digital.” Digital machines dominate today’s world, while so-called digital thinking—that is, binary thinking such as presence and absence or self and world—is often synonymous with what it means to think at all. In examining Laruelle and digitality together, Galloway shows how Laruelle remains a profoundly non-digital thinker—perhaps the only non-digital thinker today—and engages in an extensive discussion on the interconnections between media, philosophy, and technology.

The commentary interprets the practices of remembering and the creation of memory as an attempt at academic and public-media self-understanding, which exhibit past-political, present-oriented and future-oriented perspectives and intentions. Academic politics of history and remembrance can hardly be imagined without reference to and interaction with the public and politics. The contributions in this special issue make it clear that a large number of public and private actors and interest groups are usually involved in memory policy controversies surrounding academics. When discussing (...) prizes, street names or school names named after academics, for example, very different logics and ideas about remembering and memory often clash. This fundamental dilemma is particularly evident in debates about controversial academics who worked before, during and after the Nazi era. (shrink)

This paper argues that if creatures are to have significant free will, then God's essential omni-benevolence and essential omnipotence cannot logically preclude Him from creating a world containing a moral evil. The paper maintains that this traditional conclusion does not need to rest on reliance on subjunctive conditionals of free will. It can be grounded in several independent ways based on premises that many will accept.

This article develops a novel theory of sport that I call ‘Confucian mutualism’. Confucian mutualism is underpinned by the Confucian Golden Rule and the Confucian conception of human dignity. It resembles the mutualist theory of sport developed by Robert L. Simon in maintaining that sport participants ethically ought to prioritize promoting sporting excellence both in themselves and in their co-participants. However, while Simon’s mutualism maintains that sporting excellence consists in proficiency at sport constitutive skills, Confucian mutualism maintains that sporting excellence (...) consists in success at achieving the Confucian virtues through sport participation. I provide a preliminary case for why Confucian mutualism’s virtue-centric conception of sporting excellence makes it better able than Simon’s mutualism to explain why sporting excellence is stance-independently ethically significant for all sport participants. I do so by trying to show that we have prima facie justification for believing that Confucian mutualism is not vulnerable to certain kinds of criticisms that have been leveled at Simon’s mutualism.

Always connect—that is the imperative of today’s media. But what about those moments when media cease to function properly, when messages go beyond the sender and receiver to become excluded from the world of communication itself—those messages that state: “There will be no more messages”? In this book, Alexander R. Galloway, Eugene Thacker, and McKenzie Wark turn our usual understanding of media and mediation on its head by arguing that these moments reveal the ways the impossibility of communication is (...) integral to communication itself—instances they call excommunication. In three linked essays, _Excommunication_ pursues this elusive topic by looking at mediation in the face of banishment, exclusion, and heresy, and by contemplating the possibilities of communication with the great beyond. First, Galloway proposes an original theory of mediation based on classical literature and philosophy, using Hermes, Iris, and the Furies to map out three of the most prevalent modes of mediation today—mediation as exchange, as illumination, and as network. Then, Thacker goes boldly beyond Galloway’s classification scheme by examining the concept of excommunication through the secret link between the modern horror genre and medieval mysticism. Charting a trajectory of examples from H. P. Lovecraft to Meister Eckhart, Thacker explores those instances when one communicates or connects with the inaccessible, dubbing such modes of mediation “haunted” or “weird” to underscore their inaccessibility. Finally, Wark evokes the poetics of the infuriated swarm as a queer politics of heresy that deviates from both media theory and the traditional left. He posits a critical theory that celebrates heresy and that is distinct from those that now venerate Saint Paul. Reexamining commonplace definitions of media, mediation, and communication, _Excommunication_ offers a glimpse into the realm of the nonhuman to find a theory of mediation adequate to our present condition.

American criminal law is committed to some version of the doctrine of double effect. In this paper, I defend a new variant of the agent-centered rationale for a version of DDE that is of particular relevance to the criminal law. In particular, I argue for a non-absolute version of DDE that concerns the relative culpability of intending a bad or wrongful state of affairs as opposed to bringing it about merely knowingly. My aim is to identify a particular feature of (...) the former in virtue of which it is pro tanto more culpable than the latter. Providing an agent-centered argument of this kind for a culpability version of DDE, I argue, is an especially attractive route to take for those who are interested in vindicating the way the criminal law actually encodes DDE.

One recently popular way to characterise strong emergence is to say that emergent entities possess novel causal powers. However, there is little agreement concerning the nature of powers. One controversy involves whether powers are single- or multi-track; that is, whether each power has only one manifestation type, or whether a single power can be directed towards a number of distinct manifestations. Another concerns how powers operate: whether a lone power manifests when triggered by the presence of a suitable stimulus, or (...) whether powers operate mutually such that several powers must ‘work together’ to bring about a particular manifestation. This paper examines how these distinctions—which can be cross-combined to frame four distinct accounts of the nature of powers—bear on the debate between emergentists and reductionists. (shrink)

Social and behavioral scientists - that is, students of human nature - nowadays hardly ever use the term ‘human nature’. This reticence reflects both a becoming modesty about the aims of their disciplines and a healthy skepticism about whether there is any one thing really worthy of the label ‘human nature’.
