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.

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)

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)

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)

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)

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)

Anti-realism about the foundations of logic are curiously absent from the literature. This is especially striking given natural analogies with moral anti-realis.

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.

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.

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.

To what extent are cognitive capacities, especially perceptual capacities, informationally encapsulated and to what extent are they cognitively penetrable? And why does this matter? Two reasons we care about encapsulation/penetrability are: (a) encapsulation is sometimes held to be definitional of modularity, and (b) penetrability has epistemological implications independent of modularity. I argue that modularity does not require encapsulation; that modularity may have epistemological implications independently of encapsulation; and that the epistemological implications of the cognitive penetrability of perception are messier than (...) is sometimes thought.

In our wakeful conscious lives, the experience of time and dynamic temporal phenomena—such as continuous motion and change—appears to be ubiquitous. How is it that temporality is woven into our conscious experience? Is it through perceptual experience presenting a series of instantaneous states of the world, which combine together—in a sense which would need to be specified—to give us experience of dynamic temporal phenomena? In this paper, I argue that this is not the case. -/- Several authors have recently proposed (...) dynamic snapshot models of temporal experience— such as Prosser and Arstila, building upon Le Poidevin— according to which perceptual experience has no temporal content of a non‐zero extent. I argue that there is an absence of motivation for such a view; I develop and defend the claim that perceptual experience minimally presents something of some non‐zero temporal extent as such.

This paper argues for two propositions. (I) Large asymmetries of power, status and influence exist between economists. These asymmetries constitute a hierarchy that is steeper than it could be and steeper than hierarchies in other disciplines. (II) This situation has potentially significant epistemic consequences. I collect data on the social organization of economics to show (I). I then argue that the hierarchy in economics heightens conservative selection biases, restricts criticism between economists and disincentivizes the development of novel research. These factors (...) together constrain economics’ capacity to develop new beliefs and reduce the likelihood that its outputs will be true. (shrink)

This paper is concerned with the senses in which paintings do and do not depict various temporal phenomena, such as motion, stasis and duration. I begin by explaining the popular – though not uncontroversial – assumption that depiction, as a pictorial form of representation, is a matter of an experiential resemblance between the pictorial representation and that which it is a depiction of. Given this assumption, I illustrate a tension between two plausible claims: that paintings do not depict motion in (...) the sense that video recordings do, and that paintings do not merely depict objects but may depict those objects as engaged in various activities, such as moving. To resolve the tension, I demonstrate that we need to recognise an ambiguity in talk of the appearance of motion, and distinguish between the depiction of motion and the depiction of an object as an object that is moving. Armed with this distinction, I argue that there is an important sense in which paintings depict neither motion, duration, nor – perhaps more controversially – stasis. (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.

Jason Brown started his career as a neurologist specializing in language disorders, perceptive illusions, and impaired action. But beyond his activity as a physician he is a man of genuinely theoretical appetite. As satisfying as it is to help improve the situation of sick fellow humans, this alone does not characterize him well. Those who know him closer know his insistent urge to find a philosophical framework for his clinical practice and research, together with his desire for a more humane (...) society. Those who do not know him will see this immediately when they read his most recent book Process and the authentic life (Brown 2006). This is, in a nutshell, how and why Brown came to look into process philosophy, as an alternative to philosophical systems focusing on substances such as the Cartesian res cogitans and res extensa, on which science and technology are essentially based. Process philosophy holds some radical deviations from these systems, and may be regarded as complementary to them (Roemer 2006), although any such convergence is hotly contested (e.g., Bickhard 2004). Best known among adherents of a process worldview is Whitehead with his opus magnum Process and Reality. Brown’s approach is clearly in the spirit of Whitehead’s. However, due to his medical and psychological background it differs in motivation, and consequently it differs in the way it is carried out. While Whitehead, originally a mathematician, tried to be as precise and detailed as possible in his definitions, arguments and conclusions, Brown strives for his humanistic goal more directly. His accounts are based on examples rather than formal inferences, everyday experiences rather than abstract constructions. (shrink)

This essay posits the existence of two forms of disavowal: cynical and fetishistic. It explores how cynical disavowal involves maintaining a manipulative distance by obscuring the gap between belief and action, allowing the cynic to disavow their investment in an unattainable object and their knowledge of the Other’s lack. In contrast, fetishistic disavowal acknowledges both the objective reality of things and their subjective appearance to the fetishist. Unlike cynicism, fetishism does not rely on obscuring the gap between belief and action; (...) instead, it recognizes and embraces both aspects. In doing so, the essay highlights significant differences between the manipulative distance of the cynic and the self-awareness of the fetishist. It acknowledges the role of cynicism in maintaining the limits and prohibitions within ideology and authority, through examples of banality, while also emphasizing the unique qualities of fetishistic disavowal.

We regularly talk of the experience of time passing. Some theorists have taken the supposed phenomenology of time passing to provide support for metaphysical accounts of the nature of time; opposing theorists typically granted that there is a phenomenology of time passing while seeking to dispute that any metaphysical conclusions about time can be drawn from this. In recent debates theorists have also begun to dispute that there is a phenomenology of time passing – plausibly, if there is not, then (...) there is no relevant experience to be explained away, or for metaphysical conclusions to be drawn from. In the present paper I offer one explanation of why such disputes about the experience of time passing may seem intractable. However, I suggest that there is a distinct and more tractable issue lurking in this area, concerning our experience of how certain phenomena persist over time. Interestingly, articulating how we experience different phenomena as persisting over time doesn't simply provide a challenge to one metaphysical view of persistence rather than another; instead, it generates an explanatory challenge for a variety of competing views of persistence and, by extension, a challenge for popular combinations of views of the metaphysics of persistence and of time.

Ascriptions of objectivity carry significant weight. But they can also cause confusion because wildly different ideas of what it means to be objective are common. Faced with this, some philosophers have argued that objectivity should be eliminated. I will argue, against one such position, that objectivity can be useful even though it is plural. I will then propose a contextualist approach for dealing with objectivity as a way of rescuing what is useful about objectivity while acknowledging its plurality.

There are many tangled normative and technical questions involved in evaluating the quality of software used in epidemiological simulations. In this paper we answer some of these questions and offer practical guidance to practitioners, funders, scientific journals, and consumers of epidemiological research. The heart of our paper is a case study of the Imperial College London covid-19 simulator, set in the context of recent work in epistemology of simulation and philosophy of epidemiology.

It has recently been argued that hope is polysemous in that it sometimes refers to hoping and other times to being hopeful. That it has these two distinct senses is reflected in the observation that a person can hope for an outcome without being hopeful that it will occur. Below, I offer a new argument for this distinction. My strategy is to show that accepting this distinction yields a rich account of two distinct ways in which hope can be lost, (...) ways that map onto the two senses of hope: A person can lose hope either by ceasing to hope for an outcome (hopelessness) or by ceasing to be hopeful that it will obtain (despair). Thinking about these negative attitudes in these two ways, I contend, is explanatorily rich and fruitfully reveals how they differ in phenomenology, behavioral differences, and the ways in which a person can escape them.

Near the end of the long and often convoluted discussion of freedom in the chapter ‘Of Power’ in An Essay concerning Human Understanding, Locke states that in ‘The care of ourselves, that we mistake not imaginary for real happiness, is the necessary foundation of our liberty’. He goes on to explain that ‘we are by the necessity of preferring and pursuing true happiness as our greatest good, obliged to suspend the satisfaction of our desire in particular cases’. Locke then adds (...) that the ability to suspend our desires in particular cases is ‘the hinge on which turns the liberty of intellectual Beings’. Unfortunately, this hinge has proved a serious stumbling block for commentators. After three hundred years, serious scholarly disagreement remains about even the central orientation of Locke’s views on freedom. Locke was aware of the opacity surrounding portions of his discussion of liberty. In letters to several correspondents, he confesses to almost leaving it out of the first edition, fearing that ‘the novelty and subtlety of the matter itself... [would be taken] as the paradoxes of an innovator or the stumblings of an ill-advised wanderer’. As evidence that his worries were not far wrong, Locke adds that amongst his friends, ‘more have entered into discussion with... [me] about this one subject than about all the remaining chapters of the book’. My entry into this controversy will be by way of Leibniz, one of Locke’s earliest and most astute commentators.

A study of selected popular literature on Spinoza for the Blackwell Companion to Spinoza.

Raftopoulos’s most recent book argues, among other things, for the cognitive impenetrability of early vision. Before we can assess any such claims, we need to know what’s meant by “early vision” and by “cognitive penetration”. In this contribution to this book symposium, I explore several different things that one might mean – indeed, that Raftopoulos might mean – by these terms. I argue that whatever criterion we choose for delineating early vision, we need a single criterion, not a mishmash of (...) distinct criteria. And I argue against defining cognitive penetration in partly epistemological terms, although it is fine to offer epistemological considerations in defending some definitions as capturing something of independent interest. Finally, I raise some questions about how we are to understand the “directness” of certain putative cognitive influences on perception and about whether there’s a decent rationale for restricting directness in the way that Raftopoulos apparently does.

Having initially not had the attention of Sartre or Heidegger, Merleau-Ponty's work is arguably now more widely influential than either of his two contemporaries. "Merleau-Ponty: Key Concepts" presents an accessible guide to the core ideas which structure Merleau-Ponty's thinking as well as to his influences and the value of his ideas to a wide range of disciplines. The first section of the book presents the context of Merleau-Ponty's thinking, the major debates of his time, particularly existentialism, phenomenology, the history of (...) philosophy and the philosophy of history and society. The second section outlines his major contributions and conceptual innovations. The final section focuses upon how his work has been taken up in other fields besides philosophy, notably in sociology, cognitive science, health studies, feminism and race theory. (shrink)

Rather, to ensure their own health, doctors should discover other passions that permit them periodically to disconnect from medical practice.

Hope helps alleviate suffering. In the case of terminal illness, recent experience in palliative medicine has taught physicians that hope is durable and often thrives even in the face of imminent death. In this article, I examine the perspectives of philosophers, theologians, psychologists, clinicians, neuroscientists, and poets, and provide a series of observations, connections, and gestures about hope, particularly about what I call “deep hope.” I end with some proposals about how such hope can be sustained and enhanced at the (...) end of life. Studies of terminally ill patients have revealed clusters of personal and situational factors associated with enhancement or suppression of hope at the end of life. Interpersonal connectedness, attainable goals, spiritual beliefs and practices, personal attributes of determination, courage, and serenity, lightheartedness, uplifting memories, and affirmation of personal worth enhance hope, while uncontrollable pain and discomfort, abandonment and isolation, and devaluation of personhood suppress hope. I suggest that most of these factors can be modulated by good medical care, utilizing basic interpersonal techniques that demonstrate kindness, humanity, and respect. (shrink)

That Piagetian epistemology has the dynamics of knowledge growth as its core consideration predetermines a need to consider it as potentially applicable to teaching. This paper addresses that need by first outlining the Piagetian theory of equilibration and then applying it to the construction of methods of teaching science.

Best-selling books such as Freakonomics and The Undercover Economist have paved the way for the flourishing economics-made-fun genre. While books like these present economics as a strong and explanatory science, the ongoing economic crisis has exposed the shortcomings of economics to the general public. In the face of this crisis, many people, including well-known economists such as Paul Krugman, have started to express their doubts about whether economics is a success as a science. As well as academic papers, newspaper columns (...) with a large audience have discussed the failure of economic to predict and explain ongoing trends. The emerging picture is somewhat confusing: economics-made-fun books present economics as a method of thinking that can successfully explain everyday and "freaky" phenomena. On the other hand, however, economics seems to fail in addressing and explaining the most pressing matters related to the field of economics itself. This book explores the confusion created by this contradictory picture of economics. Could a science that cannot answer its own core questions really be used to explain the logic of everyday life? This book was originally published as a special issue of the Journal of Economic Methodology. (shrink)

This paper examines transhuman technologies that seek to eradicate disability - primarily prostheses and implants. While most would agree that disability denies individuals the same quality of life as those deemed “abled,” this eradication ultimately relies upon secular humanist notions of the perfect human. Transhuman technologies hold obvious implications for the human body, however they also hold implications for what it means to be an acceptable body; ultimately these technologies aim to create the perfect human by eradicating the disabled Other. (...) This paper uses these notions to question concepts of “hierarchies of life,” at which disabled individuals are most commonly moved towards the bottom, or at the very least considered nonhuman. This article seeks to provide alternative theory to the eradication of disability, which states that these individuals may not have the same mode of existence, but that their mode/s are just as valid as those lived by “abled” individuals through an examination of Braille.

This paper explores how open-mindedness and its exercise can be social in nature. In particular, it argues that an individual can be regarded as open-minded even though she does not conduct all of the intellectual tasks as required by open-mindedness _by herself;_ that is, she delegates some of these tasks to her epistemic peers. Thinking about open-mindedness in such social terms not only opens up the possibility that there are different and surprising ways for an individual to be open-minded, but (...) can also help offset some recent criticisms raised against open-mindedness and its status as an intellectual virtue.

The purpose of this article is twofold. First, it explores and shows ways in which one important view of racism parallels the Christian doctrine of original sin. Second, it argues that this comparison helps to close the gap between the two main strands of Christian thinking about original sin. Philosophers and theologians are often asked to decide between Augustinian or Irenaean theories of original sin. An epistemology of ignorance, especially as applied in discussions of racism, helps us to see how (...) this dichotomy may be short‐sighted. For virtually no one, in an epistemology of ignorance, matures into being a racist. Nevertheless, as Charles W. Mills famously argues, the epistemology of ignorance he terms the Racial Contract has a historical inception, namely, the period around the beginning of the Transatlantic Slave Trade. I close the article by discussing whether a model of original sin similar to an epistemology of racist ignorance might satisfy the dogmatic constraints of the Catholic tradition. (shrink)

It is the intent of this essay to sketch a comparison between the thought of Hegel and Kierkegaard. I will argue that their respective understanding of the logic of identity and difference, taken together, offers a dialectically holistic analysis of authentic spirit-full selfhood. By isolating a basic category of disagreement, we can possibly retain their penetrating insights while sidestepping some of the unfortunate implications in their respective positions. I hope to show that this analysis and synthesis offer a powerful model (...) for understanding the dynamics of becoming a self, and is instructive as to the epistemic status of our various philosophical and theological projects.
