I argue that we can and should extend Tarski's model-theoretic criterion of logicality to cover indefinite expressions like Hilbert's ɛ operator, Russell's indefinite description operator η, and abstraction operators like 'the number of'. I draw on this extension to discuss the logical status of both abstraction operators and abstraction principles.

It is regrettably common for theorists to attempt to characterize the Humean dictum that one can’t get an ‘ought’ from an ‘is’ just in broadly logical terms. We here address an important new class of such approaches which appeal to model-theoretic machinery. Our complaint about these recent attempts is that they interfere with substantive debates about the nature of the ethical. This problem, developed in detail for Daniel Singer’s and Gillian Russell and Greg Restall’s accounts of Hume’s dictum, is (...) of a general type arising for the use of model-theoretic structures in cashing out substantive philosophical claims: the question of whether an abstract model-theoretic structure successfully interprets something often involves taking a stand on non-trivial issues surrounding the thing. In the particular case of Hume’s dictum, given reasonable conceptual or metaphysical claims about the ethical, Singer’s and Russell and Restall’s accounts treat obviously ethical claims as descriptive and vice versa. Consequently, their model-theoretic characterizations of Hume’s dictum are not metaethically neutral. This encourages skepticism about whether model-theoretic machinery suffices to provide an illuminating distinction between the ethical and the descriptive. (shrink)

I revisit my paper, ‘Grace de Laguna’s 1909 Critique of Analytic Philosophy’ and respond to the commentary on it. I respond to James Chase and Jack Reynolds by further analysing the difference between speculative philosophy as de Laguna conceived of it and analytic philosophy, by clarifying how her critique of analytic philosophy remains relevant to some of its more speculative forms, and by explaining what justifies the criticism of established opinion that goes along with her rejection of analytic philosophy’s (...) epistemic conservatism. In response to Andreas Vrahimis, I contextualise my reading of de Laguna’s work in 1909. This clarifies her critique of pragmatism, distinguishes it from her critique of epistemically conservative philosophy, and shows that she was not only already aware of the full scope of the latter critique but is likely to have identified the then incipient analytic philosophy as its primary target. Also, contra Vrahimis, her argument is effective against Bertrand Russell’s later, epistemically conservative approach to philosophy. In response to Cheryl Misak, I point out that her argument that de Laguna is, despite herself, a pragmatist rests on a misunderstanding of the differences between pragmatism and idealism, and I show that de Laguna’s main early influences were Herbert Spencer and her teacher, James Edwin Creighton. I further argue that Misak’s rejection of de Laguna’s critique of pragmatism rests on a misrepresentation of the critique. (shrink)

In this paper, I argue that for the purposes of ordinary reasoning, sentences about properties of concrete objects can be replaced with sentences concerning how things in our universe would be related to inscriptions were there a pluriverse. Speaking loosely, pluriverses are composites of universes that collectively realize every way a universe could possibly be. As such, pluriverses exhaust all possible meanings that inscriptions could take. Moreover, because universes necessarily do not influence one another, our universe would not be any (...) different intrinsically if there were a pluriverse. These two facts enable anti-realists about abstract objects to replace, e.g. talk of anatomical features with talk of the inscriptions concerning anatomical structure that would exist were there a pluriverse. The availability of such replacements enables anti-realists to carry out essential ordinary reasoning without referring to properties, thereby making room for a consistent anti-realist worldview. The inscriptions of the would-be pluriverse are so numerous and varied that sentences about them can play the roles in ordinary reasoning served by simple sentences about properties of concrete objects. (shrink)

I investigate syntactic notions of theoretical equivalence between logical theories and a recent objection thereto. I show that this recent criticism of syntactic accounts, as extensionally inadequate, is unwarranted by developing an account which is plausibly extensionally adequate and more philosophically motivated. This is important for recent anti-exceptionalist treatments of logic since syntactic accounts require less theoretical baggage than semantic accounts.

Seeking a decision theory that can handle both the Newcomb problems that challenge evidential decision theory and the unstable problems that challenge causal decision theory, some philosophers recently have turned to ‘graded ratifiability’. However, the graded ratifiability approach to decision theory is, despite its virtues, unsatisfactory; for it conflicts with the platitude that it is always rationally permissible for an agent to knowingly choose their best option.

Expressivists explain the expression relation which obtains between sincere moral assertion and the conative or affective attitude thereby expressed by appeal to the relation which obtains between sincere assertion and belief. In fact, they often explicitly take the relation between moral assertion and their favored conative or affective attitude to be exactly the same as the relation between assertion and the belief thereby expressed. If this is correct, then we can use the identity of the expression relation in the two (...) cases to test the expressivist account as a descriptive or hermeneutic account of moral discourse. I formulate one such test, drawing on a standard explanation of Moore's paradox. I show that if expressivism is correct as a descriptive account of moral discourse, then we should expect versions of Moore's paradox where we explicitly deny that we possess certain affective or conative attitudes. I then argue that the constructions that mirror Moore's paradox are not incoherent. It follows that expressivism is either incorrect as a hermeneutic account of moral discourse or that the expression relation which holds between sincere moral assertion and affective or conative attitudes is not identical to the relation which holds between sincere non-moral assertion and belief. A number of objections are canvassed and rejected. (shrink)

The paper offers a solution to the generality problem for a reliabilist epistemology, by developing an “algorithm and parameters” scheme for type-individuating cognitive processes. Algorithms are detailed procedures for mapping inputs to outputs. Parameters are psychological variables that systematically affect processing. The relevant process type for a given token is given by the complete algorithmic characterization of the token, along with the values of all the causally relevant parameters. The typing that results is far removed from the typings of folk (...) psychology, and from much of the epistemology literature. But it is principled and empirically grounded, and shows good prospects for yielding the desired epistemological verdicts. The paper articulates and elaborates the theory, drawing out some of its consequences. Toward the end, the fleshed-out theory is applied to two important case studies: hallucination and cognitive penetration of perception. (shrink)

A natural suggestion and increasingly popular account of how to revise our logical beliefs treats revision of logic analogously to the revision of scientific theories. I investigate this approach and argue that simple applications of abductive methodology to logic result in revision-cycles, developing a detailed case study of an actual dispute with this property. This is problematic if we take abductive methodology to provide justification for revising our logical framework. I then generalize the case study, pointing to similarities with more (...) recent and popular heterodox logics such as naïve logics of truth. I use this discussion to motivate a constraint—logical partisanhood—on the uses of such methodology: roughly: both the proposed alternative and our actual background logic must be able to agree that moving to the alternative logic is no worse than staying put. (shrink)

Is perception cognitively penetrable, and what are the epistemological consequences if it is? I address the latter of these two questions, partly by reference to recent work by Athanassios Raftopoulos and Susanna Seigel. Against the usual, circularity, readings of cognitive penetrability, I argue that cognitive penetration can be epistemically virtuous, when---and only when---it increases the reliability of perception.

Etiquette and other merely formal normative standards like legality, honor, and rules of games are taken less seriously than they should be. While these standards are not intrinsically reason-providing in the way morality is often taken to be, they also play an important role in our practical lives: we collectively treat them as important for assessing the behavior of ourselves and others and as licensing particular forms of sanction for violations. This chapter develops a novel account of the normativity of (...) formal standards where the role they play in our practical lives explains a distinctive kind of reason to obey them. We have this kind of reason to be polite because etiquette is important to us. We also have this kind of reason to be moral because morality is important to us. This parallel suggests that the importance we assign to morality is insufficient to justify it being substantive. (shrink)

Philosophical debates about the metaphysics of time typically revolve around two contrasting views of time. On the A-theory, time is something that itself undergoes change, as captured by the idea of the passage of time; on the B-theory, all there is to time is events standing in before/after or simultaneity relations to each other, and these temporal relations are unchanging. Philosophers typically regard the A-theory as being supported by our experience of time, and they take it that the B-theory clashes (...) with how we experience time and therefore faces the burden of having to explain away that clash. In this paper, we investigate empirically whether these intuitions about the experience of time are shared by the general public. We asked directly for people’s subjective reports of their experience of time—in particular, whether they believe themselves to have a phenomenology as of time’s passing—and we probed their understanding of what time’s passage in fact is. We find that a majority of participants do share the aforementioned intuitions, but interestingly a minority do not. (shrink)

Sometimes a fact can play a role in a grounding explanation, but the particular content of that fact make no difference to the explanation—any fact would do in its place. I call these facts vacuous grounds. I show that applying the distinction between-vacuous grounds allows us to give a principled solution to Kit Fine and Stephen Kramer’s paradox of ground. This paradox shows that on minimal assumptions about grounding and minimal assumptions about logic, we can show that grounding is reflexive, (...) contra the intuitive character of grounds. I argue that we should never have accepted that grounding is irreflexive in the first place; the intuitions that support the irreflexive intuition plausibly only require that grounding be non-vacuously irreflexive. Fine and Kramer’s paradox relies, essentially, on a case of vacuous grounding and is thus no problem for this account. (shrink)

In this paper, I argue that all expressions for abstract objects are meaningless. My argument closely follows David Lewis’ argument against the intelligibility of certain theories of possible worlds, but modifies it in order to yield a general conclusion about language pertaining to abstract objects. If my Lewisian argument is sound, not only can we not know that abstract objects exist, we cannot even refer to or think about them. However, while the Lewisian argument strongly motivates nominalism, it also undermines (...) certain nominalist theories. (shrink)

This paper develops an argument against causal decision theory. I formulate a principle of preference, which I call the Guaranteed Principle. I argue that the preferences of rational agents satisfy the Guaranteed Principle, that the preferences of agents who embody causal decision theory do not, and hence that causal decision theory is false.

I argue that certain species of belief, such as mathematical, logical, and normative beliefs, are insulated from a form of Harman-style debunking argument whereas moral beliefs, the primary target of such arguments, are not. Harman-style arguments have been misunderstood as attempts to directly undermine our moral beliefs. They are rather best given as burden-shifting arguments, concluding that we need additional reasons to maintain our moral beliefs. If we understand them this way, then we can see why moral beliefs are vulnerable (...) to such arguments while mathematical, logical, and normative beliefs are not—the very construction of Harman-style skeptical arguments requires the truth of significant fragments of our mathematical, logical, and normative beliefs, but requires no such thing of our moral beliefs. Given this property, Harman-style skeptical arguments against logical, mathematical, and normative beliefs are self-effacing; doubting these beliefs on the basis of such arguments results in the loss of our reasons for doubt. But we can cleanly doubt the truth of morality. (shrink)

In order to better understand the topic of hope, this paper argues that two separate theories are needed: One for hoping, and the other for hopefulness. This bifurcated approach is warranted by the observation that the word ‘hope’ is polysemous: It is sometimes used to refer to hoping and sometimes, to feeling or being hopeful. Moreover, these two senses of 'hope' are distinct, as a person can hope for some outcome yet not simultaneously feel hopeful about it. I argue that (...) this distinction between hoping and hopefulness is not always observed or fully appreciated in the literature and has consequently caused much confusion. This paper then sketches what theorizing about hope looks like in light of this clarification and discusses some of its implications. (shrink)

Phenomenology has been described as a “non-argumentocentric” way of doing philosophy, reflecting that the philosophical focus is on generating adequate descriptions of experience. But it should not be described as an argument-free zone, regardless of whether this is intended as a descriptive claim about the work of the “usual suspects” or a normative claim about how phenomenology ought to be properly practiced. If phenomenology is always at least partly in the business of arguments, then it is worth giving further attention (...) to the role and form of phenomenological argumentation, how it interacts with its more strictly descriptive component, and the status of phenomenological claims regarding conditions for various kinds of experience. I contend that different versions of phenomenological reasoning encroach upon argument forms that are commonly thought to be antithetical to phenomenology, notably abductive reasoning, understood in terms of its role in both hypothesis generation and in terms of justification. This paper identifies two main steps to making this case. The first step takes seriously the consequences of the intrinsically dialectical aspect of phenomenology in intersection with other modes of philosophy, the natural attitude, and non-philosophy. The second step focuses on transcendental reflection and arguments about the conditions/structures they contain. Together, these two steps aim to rescue phenomenology from the objection that it has an “ostrich epistemology” with regard to the ostensible purity of description, the intuition of essences, or the “conditions” ascertained through transcendental reflection.

Nearly everyone agrees that perception gives us justification and knowledge, and a great number of epistemologists endorse a particular two-part view about how this happens. The view is that perceptual beliefs get their justification from perceptual experiences, and that they do so by being based on them. Despite the ubiquity of these two views, I think that neither has very much going for it; on the contrary, there’s good reason not to believe either one of them.

This paper proposes a new framework for thinking about hope, with certain unexpected consequences. Specifically, I argue that a shift in focus from locutions like “x hopes that” and “x is hoping that” to “x is hopeful that” and “x has hope that” can improve our understanding of hope. This approach, which emphasizes hopefulness as the central concept, turns out to be more revealing and fruitful in tackling some of the issues that philosophers have raised about hope, such as the (...) question of how hope can be distinguished from despair or how people can have differing strengths in hope. It also allows us to see that many current accounts of hope, far from being rivals, are actually compatible with one another. (shrink)

In this paper, I develop a "safety result" for applied mathematics. I show that whenever a theory in natural science entails some non-mathematical conclusion via an application of mathematics, there is a counterpart theory that carries no commitment to mathematical objects, entails the same conclusion, and the claims of which are true if the claims of the original theory are "correct": roughly, true given the assumption that mathematical objects exist. The framework used for proving the safety result has some advantages (...) over existing nominalistic accounts of applied mathematics. It also provides a nominalistic account of pure mathematics. (shrink)

This paper develops a form of moral actualism that can explain the procreative asymmetry. Along the way, it defends and explains the attractive asymmetry: the claim that although an impermissible option can be self-conditionally permissible, a permissible option cannot be self-conditionally impermissible.

I distinguish two ways of developing anti-exceptionalist approaches to logical revision. The first emphasizes comparing the theoretical virtuousness of developed bodies of logical theories, such as classical and intuitionistic logic. I'll call this whole theory comparison. The second attempts local repairs to problematic bits of our logical theories, such as dropping excluded middle to deal with intuitions about vagueness. I'll call this the piecemeal approach. I then briefly discuss a problem I've developed elsewhere for comparisons of logical theories. Essentially, the (...) problem is that a pair of logics may each evaluate the alternative as superior to themselves, resulting in oscillation between logical options. The piecemeal approach offers a way out of this problem andthereby might seem a preferable to whole theory comparisons. I go on to show that reflective equilibrium, the best known piecemeal method, has deep problems of its own when applied to logic. (shrink)

What is the phenomenology of hope? A common view is that hope has a generally positive and pleasant affective tone. This rosy depiction, however, has recently been challenged. Certain hopes, it has been objected, are such that they are either entirely negative in valence or neutral in tone. In this paper, I argue that this challenge has only limited success. In particular, I show that it only applies to one sense of hope but leaves another sense—one that is implicitly but (...) widely employed in the hope literature—untouched. Moreover, I argue that hope construed in this latter sense is inherently positively valenced. The paper concludes by discussing some of the implications of this defense of hope's positive phenomenology, including the ontological question of whether hope is an emotion. (shrink)

The New Evil Demon Problem is supposed to show that straightforward versions of reliabilism are false: reliability is not necessary for justification after all. I argue that it does no such thing. The reliabilist can count a number of beliefs as justified even in demon worlds, others as unjustified but having positive epistemic status nonetheless. The remaining beliefs---primarily perceptual beliefs---are not, on further reflection, intuitively justified after all. The reliabilist is right to count these beliefs as unjustified in demon worlds, (...) and it is a challenge for the internalist to be able to do so as well. (shrink)

Response to Horgan, Goldman, and Graham. Part of a book symposium on my _Perception and Basic Beliefs_.

Recasting Hume and Early Modern Philosophy is a collection of essays that are all concerned with major figures and topics in the early modern philosophy. Most of the essays are concerned, more specifically, with the philosophy of David Hume (1711-1776). The sixteen essays included in this collection are divided into five parts. These parts are arranged under the headings of: (1) Metaphysics and Epistemology; (2) Free Will and Moral Luck; (3) Ethics, Virtue and Optimism; (4) Skepticism, Religion and Atheism; and (...) (5) Irreligion and the Unity of Hume’s Thought. A particularly important theme running through many of these essays is the subject of Hume’s irreligious aims and intentions. The fifth and final part of the collection is devoted to an articulation and defence of this specific understanding of Hume’s philosophical thought. (shrink)

Can beliefs that are not consciously formulated serve as part of an agent's evidence for other beliefs? A common view says no, any belief that is psychologically immediate is also epistemically immediate. I argue that some unconscious beliefs can serve as evidence, but other unconscious beliefs cannot. Person-level beliefs can serve as evidence, but subpersonal beliefs cannot. I try to clarify the nature of the personal/subpersonal distinction and to show how my proposal illuminates various epistemological problems and provides a principled (...) framework for solving other problems. (shrink)

I argue that the social dimension of alienation, as discussed by Williams and Railton, has been underappreciated. The lesson typically drawn from their exchange is that moral theory poses a threat to the internal integrity of the agent, but there is a parallel risk that moral theory will implicitly construe agents as constitutively alienated from one another. I argue that a satisfying account of agency will need to make room for what I call ‘genuine ethical contact’ with others, both as (...) concrete objects in the world external to ourselves and as subjects who can recognize us reciprocally. (shrink)

Cognitive penetration of perception is the idea that what we see is influenced by such states as beliefs, expectations, and so on. A perceptual belief that results from cognitive penetration may be less justified than a nonpenetrated one. Inferentialism is a kind of internalist view that tries to account for this by claiming that some experiences are epistemically evaluable, on the basis of why the perceiver has that experience, and the familiar canons of good inference provide the appropriate standards by (...) which experiences are evaluated. I examine recent defenses of inferentialism by Susanna Siegel, Peter Markie, and Matthew McGrath and argue that the prospects for inferentialism are dim. (shrink)

Consequentialists often assume rational monism: the thesis that options are always made rationally permissible by the maximization of the selfsame quantity. This essay argues that consequentialists should reject rational monism and instead accept rational pluralism: the thesis that, on different occasions, options are made rationally permissible by the maximization of different quantities. The essay then develops a systematic form of rational pluralism which, unlike its rivals, is capable of handling both the Newcomb problems that challenge evidential decision theory and the (...) unstable problems that challenge causal decision theory.

Iris Murdoch’s The Sovereignty of Good—especially the first essay, “The Idea of Perfection”—is often associated with a critique of a certain picture of agency and its proper place in ethical thought. There is implicit in this critique, however, an alternative, much richer one. I propose a reading of Murdochian agency in terms of the continuous activity of cultivating and refining a distinctive practical standpoint, and I apply this reading to her account of moral progress. For Murdoch moral progress depends on (...) transcending egoism and achieving clear perception of a normatively-saturated reality, but it would be a mistake to think of egoism in terms of selfishness, or clarity in terms of altruism. Rather, I argue, Murdochian moral progress requires overcoming socially-conditioned and often ideological forms of alienation, and making the social conditions that inform our practical standpoints self-conscious.

This paper will seek firstly to understand Deleuze’s main challenges to phenomenology, particularly as they are expressed in The Logic of Sense and What is Philosophy?, although reference will also be made to Pure Immanence and Difference and Repetition. We will then turn to a discussion of one of the few passages in which Deleuze directly engages with Merleau-Ponty, which occurs in the chapter on art in What is Philosophy? In this text, he and Guattari offer a critique of what (...) they call the “final avatar” of phenomenology – that is, the “fleshism” that Merleau-Ponty proposes in his unfinished but justly famous work, The Visible and the Invisible. It will be argued that both Deleuze’s basic criticisms of phenomenology, as well as he and Guattari’s problems with the concept of the flesh, do not adequately come to grips with Merleau-Ponty’s later philosophy. Merleau-Ponty is not obviously partisan to what Deleuze finds problematic in this tradition, despite continuing to identify himself as a phenomenologist, and is working within a surprisingly similar framework in certain key respects. In fact, in the more positive part of this paper, we will compare Merleau-Ponty’s notion of flesh, and Deleuze’s equally infamous univocity of being, as a means to consider the broader question of the ways in which the two philosophers consider ontological thought, its meaning and its conditions. It is our belief that through properly understanding both positions, a rapprochement, or at least the foundation for one, can be established between these two important thinkers. (shrink)

I argue that metaethicists should be concerned with two kinds of alienation that can result from theories of normativity: alienation between an agent and her reasons, and alienation between an agent and the concrete others with whom morality is principally concerned. A theory that cannot avoid alienation risks failing to make sense of central features of our experience of being agents, in whose lives normativity plays an important role. The twin threats of alienation establish two desiderata for theories of normativity; (...) however, I argue that they are difficult to jointly satisfy. (shrink)

As neither a classical naturalist nor a non-naturalist, Merleau-Ponty appears to be a moderate or liberal naturalist. But can a phenomenologist really be a naturalist, even a liberal one? A lot hinges on how we tease this out, both as to whether it is plausible to claim Merleau-Ponty as a liberal naturalist (I argue it is), and as to whether it is an attractive and coherent position. Indeed, despite its important challenges to orthodox naturalism, there are arguably two traps to (...) avoid. If it becomes too liberal, we get: dualism or an ontological pluralism that is difficult to distinguish from a constructivism; or, in seeking to sidestep that metaphysical dilemma, there is sometimes an insistence on an overly neat methodological separation between description/understanding and explanation that is belied in practice (both scientific and philosophical). It is doubtful that such positions can legitimately claim to be naturalist in orientation, liberal or not. Merleau-Ponty’s philosophy avoids these traps, however, and it is thus a useful resource for contemporary work trying to navigate between scientific naturalism and non-naturalism. (shrink)

Domestic violence and abuse (DVA) are at last coming to be recognised as serious global public health problems. Nevertheless, many women with personal histories of DVA decline to disclose them to healthcare practitioners. In the health sciences, recent empirical work has identified many factors that impede DVA disclosure, known as barriers to disclosure. Drawing on recent work in social epistemology on testimonial silencing, we might wonder why so many people withhold their testimony and whether there is some kind of epistemic (...) injustice afoot here. In this paper, I offer some philosophical reflections on DVA disclosure in clinical contexts and the associated barriers to disclosure. I argue that women with personal histories of DVA are vulnerable to a certain form of testimonial injustice in clinical contexts, namely, testimonial smothering, and that this may help to explain why they withhold that testimony. It is my contention that this can help explain the low rates of DVA disclosure by patients to healthcare practitioners. (shrink)

The Psychosis of Race offers a unique and detailed account of the psychoanalytic significance of race, and the ongoing impact of racism in contemporary society. Moving beyond the well-trodden assertion that race is a social construction, and working against demands that simply call for more representational equality, The Psychosis of Race explores how the delusions, anxieties, and paranoia that frame our race relations can afford new insights into how we see, think, and understand race's pervasive appeal. With examples drawn from (...) politics and popular culture--such as Candyman, Get Out, and the music of Kendrick Lamar--critical attention is given to introducing as well as explicating on several key concepts from Lacanian psychoanalysis and the study of psychosis, including foreclosure, phallus, the Name-of-the-Father, sinthome, and the objet petit a. By elaborating a cultural mode to psychosis and its understanding, an original and critical exposition of the effects of racialization, as well as our ability to discern the very limits of our capacity to think through, or even beyond, the idea of race, is provided. The Psychosis of Race speaks to an emerging area in the study of psychoanalysis and race, and will appeal to scholars and academics across the fields of psychology, sociology, cultural studies, media studies, and the arts and humanities.

The paper argues that Spinoza may have deepened his conception of poetry as not only a resource for the understanding but as the highest peak of the understanding. I begin by reviewing selected literature on Spinoza’s views on language and show how Spinoza’s presentation of his philosophy builds on a conception of what language can do. I then make a succinct case for a reading of Ethics Part 5 Proposition 24, where we find an attempt at a poetic expression of (...) thought, as Spinoza explores what he considers the highest form of knowledge: intuitive science.

This paper develops a view on which: (a) all fundamental facts are absolute, (b) some facts do not supervene on the fundamental facts, and (c) only relative facts fail to supervene on the fundamental facts.

By a `denoting phrase' I mean a phrase such as any one of the following: a man, some man, any man, every man, all men, the present King of England, the present King of France, the center of mass of the solar system at the first instant of the twentieth century, the revolution of the earth round the sun, the revolution of the sun round the earth. Thus a phrase is denoting solely in virtue of its form. We may distinguish (...) three cases: (1) A phrase may be denoting, and yet not denote anything; e.g., `the present King of France'. (2) A phrase may denote one definite object; e.g., `the present King of England' denotes a certain man. (3) A phrase may denote ambiguously; e.g. `a man' denotes not many men, but an ambiguous man. The interpretation of such phrases is a matter of considerably difficulty; indeed, it is very hard to frame any theory not susceptible of formal refutation. All the difficulties with which I am acquainted are met, so far as I can discover, by the theory which I am about to explain. (shrink)

Why do promises give rise to reasons? I consider a quadruple of possibilities which I think will not work, then sketch the explanation of the normativity of promising I find more plausible—that it is constitutive of the practice of promising that promise-breaking implies liability for blame and that we take liability for blame to be a bad thing. This effects a reduction of the normativity of promising to conventionalism about liability together with instrumental normativity and desire-based reasons. This is important (...) for a number of reasons, but the most important reason is that this style of account can be extended to account for nearly all normativity—one notable exception being instrumental normativity itself. Success in the case of promises suggests a general reduction of normativity to conventions and instrumental normativity. But success in the cases of promises is already quite interesting and does not depend essentially the general claim about normativity. (shrink)

The Limits of Free Will presents influential articles by Paul Russell concerning free will and moral responsibility. The problems arising in this field of philosophy, which are deeply rooted in the history of the subject, are also intimately related to a wide range of other fields, such as law and criminology, moral psychology, theology, and, more recently, neuroscience. These articles were written and published over a period of three decades, although most have appeared in the past decade. Among the (...) topics covered: the challenge of skepticism; moral sentiment and moral capacity; necessity and the metaphysics of causation; practical reason; free will and art; fatalism and the limits of agency; moral luck, and our metaphysical attitudes of optimism and pessimism.

Two lines of evidence indicate that there exists a reciprocal inhibitory relationship between opposed brain networks. First, most attention-demanding cognitive tasks activate a stereotypical set of brain areas, known as the task-positive network and simultaneously deactivate a different set of brain regions, commonly referred to as the task negative or defaultmode network. Second, functional connectivity analyses show that these same opposed networks are anti-correlated in the resting state. Wehypothesize that these reciprocally inhibitory effects reflect two incompatible cognitive modes, each of (...) which may be directed towards understanding the external world. Thus, engaging onemode activates one set of regions and suppresses activity in the other.Wetest this hypothesis by identifying two types of problem-solving task which, on the basis of prior work, have been consistently associated with the task positive and task negative regions: tasks requiring social cognition, i.e., reasoning about the mental states of other persons, and tasks requiring physical cognition, i.e., reasoning about the causal/mechanical properties of inanimate objects. Social and mechanical reasoning tasks were presented to neurologically normal participants during fMRI. Each task type was presented using both text and video clips. Regardless of presentation modality, we observed clear evidence of reciprocal suppression: social tasks deactivated regions associated with mechanical reasoning and mechanical tasks deactivated regions associated with social reasoning. These findings are not explained by self-referential processes, task engagement, mental simulation,mental time travel or external vs. internal attention, all factors previously hypothesized to explain default mode network activity. Analyses of resting state data revealed a close match between the regions our tasks identified as reciprocally inhibitory and regions of maximal anti-correlation in the resting state. These results indicate the reciprocal inhibition is not attributable to constraints inherent in the tasks, but is neural in origin. Hence, there is a physiological constraint on our ability to simultaneously engage two distinct cognitive modes. Furtherwork is needed tomore precisely characterize these opposing cognitive domains.

Much of the intuitive appeal of evidentialism results from conflating two importantly different conceptions of evidence. This is most clear in the case of perceptual justification, where experience is able to provide evidence in one sense of the term, although not in the sense that the evidentialist requires. I argue this, in part, by relying on a reading of the Sellarsian dilemma that differs from the version standardly encountered in contemporary epistemology, one that is aimed initially at the epistemology of (...) introspection but which generalizes to theories of perceptual justification as well.

This volume celebrates the various facets of Alan Turing (1912–1954), the British mathematician and computing pioneer, widely considered as the father of computer science. It is aimed at the general reader, with additional notes and references for those who wish to explore the life and work of Turing more deeply. -/- The book is divided into eight parts, covering different aspects of Turing’s life and work. -/- Part I presents various biographical aspects of Turing, some from a personal point of (...) view. -/- Part II presents Turing’s universal machine (now known as a Turing machine), which provides a theoretical framework for reasoning about computation. His 1936 paper on this subject is widely seen as providing the starting point for the field of theoretical computer science. -/- Part III presents Turing’s working on codebreaking during World War II. While the War was a disastrous interlude for many, for Turing it provided a nationally important outlet for his creative genius. It is not an overstatement to say that without Turing, the War would probably have lasted longer, and may even have been lost by the Allies. The sensitive nature of Turning’s wartime work meant that much of this has been revealed only relatively recently. -/- Part IV presents Turing’s post-War work on computing, both at the National Physical Laboratory and at the University of Manchester. He made contributions to both hardware design, through the ACE computer at the NPL, and software, especially at Manchester. Part V covers Turing’s contribution to machine intelligence (now known as Artificial Intelligence or AI). Although Turing did not coin the term, he can be considered a founder of this field which is still active today, authoring a seminal paper in 1950. -/- Part VI covers morphogenesis, Turing’s last major scientific contribution, on the generation of seemingly random patterns in biology and on the mathematics behind such patterns. Interest in this area has increased rapidly in recent times in the field of bioinformatics, with Turing’s 1952 paper on this subject being frequently cited. -/- Part VII presents some of Turing’s mathematical influences and achievements. Turing was remarkably free of external influences, with few co-authors – Max Newman was an exception and acted as a mathematical mentor in both Cambridge and Manchester. -/- Part VIII considers Turing in a wider context, including his influence and legacy to science and in the public consciousness. -/- Reflecting Turing’s wide influence, the book includes contributions by authors from a wide variety of backgrounds. Contemporaries provide reminiscences, while there are perspectives by philosophers, mathematicians, computer scientists, historians of science, and museum curators. Some of the contributors gave presentations at Turing Centenary meetings in 2012 in Bletchley Park, King’s College Cambridge, and Oxford University, and several of the chapters in this volume are based on those presentations – some through transcription of the original talks, especially for Turing’s contemporaries, now aged in their 90s. Sadly, some contributors died before the publication of this book, hence its dedication to them. -/- For those interested in personal recollections, Chapters 2, 3, 11, 12, 16, 17, and 36 will be of interest. For philosophical aspects of Turing’s work, see Chapters 6, 7, 26–31, and 41. Mathematical perspectives can be found in Chapters 35 and 37–39. Historical perspectives can be found in Chapters 4, 8, 9, 10, 13–15, 18, 19, 21–25, 34, and 40. With respect to Turing’s body of work, the treatment in Parts II–VI is broadly chronological. We have attempted to be comprehensive with respect to all the important aspects of Turing’s achievements, and the book can be read cover to cover, or the chapters can be tackled individually if desired. There are cross-references between chapters where appropriate, and some chapters will inevitably overlap. -/- We hope that you enjoy this volume as part of your library and that you will dip into it whenever you wish to enter the multifaceted world of Alan Turing.

Exploring online criticisms of the ‘take the knee’ protest during ‘Euro 2020’, this article examines how alt- and far-right conspiracies were both constructed and communicated via the social media platform, Twitter. By providing a novel exploration of alt-right conspiracies during an international football tournament, a qualitative thematic analysis of 1,388 original tweets relating to Euro 2020 was undertaken. The findings reveal how, in criticisms levelled at both ‘wokeism’ and the Black Lives Matter movement, antiwhite criticisms of the ‘take the knee’ (...) protest were embroiled in alt-right conspiracies that exposed an assumed Cultural Marxist, ‘woke agenda’ in the tournament’s organization and mainstream media coverage. In conclusion, it is argued that conspiratorial discourses, associated with the alt-right, provided a framework through which the protest could be understood. This emphasises how the significance of conspiracy functions to promote the wider dissemination of alt-right ideology across popular cultural contexts, such as sport. (shrink)

Outside of philosophy, ‘intuition’ means something like ‘knowing without knowing how you know’. Intuition in this broad sense is an important epistemological category. I distinguish intuition from perception and perception from perceptual experience, in order to discuss the distinctive psychological and epistemological status of evaluative property attributions. Although it is doubtful that we perceptually experience many evaluative properties and also somewhat unlikely that we perceive many evaluative properties, it is highly plausible that we intuit many instances of evaluative properties as (...) such. The resulting epistemological status of evaluative property attributions is very much like it would be if we literally perceived such properties. (shrink)

Despite the widespread presence of public arts funding in liberal societies, some liberals find it unjustified. According to the Neutrality Objection, arts funding preferences some ways of life. One way to motivate this challenge is to say that a public goods-styled justification, although it could relieve arts funding of these worries of partiality, cannot be argued for coherently or is, in the end, too susceptible to impressions of partiality. I argue that diversity-based arts funding can overcome this challenge, because it (...) invests in non-excludable infrastructure that fosters cultural literacy. We all have some interest as citizens in living in a society which fosters cultural literacy, seeing as this helps others to understand us, supports us to understand ourselves, and helps alleviate confusion and alienation we feel toward social difference. While some of these benefits can be enjoyed by those who make and consume art, they are also gained by those who don’t, because arts funding affects the makeup of public spaces and the communicative practices we all use to make sense of the world.
