A growing body of empirical literature challenges philosophers’ reliance on intuitions as evidence based on the fact that intuitions vary according to factors such as cultural and educational background, and socio‐economic status. Our research extends this challenge, investigating Lehrer’s appeal to the Truetemp Case as evidence against reliabilism. We found that intuitions in response to this case vary according to whether, and which, other thought‐experiments are considered first. Our results show that compared to subjects who receive the Truetemp Case first, (...) subjects first presented with a clear case of knowledge are less willing to attribute knowledge in the Truetemp Case, and subjects first presented with a clear case of non‐knowledge are more willing to attribute knowledge in the Truetemp Case. We contend that this instability undermines the supposed evidential status of these intuitions, such that philosophers who deal in intuitions can no longer rest comfortably in their armchairs.

We provide a taxonomy of the two most important debates in the philosophy of the cognitive and neural sciences. The first debate is over methodological individualism: is the object of the cognitive and neural sciences the brain, the whole animal, or the animal--environment system? The second is over explanatory style: should explanation in cognitive and neural science be reductionist-mechanistic, inter-level mechanistic, or dynamical? After setting out the debates, we discuss the ways in which they are interconnected. Finally, we make some (...) recommendations that we hope will help philosophers interested in the cognitive and neural sciences to avoid dead ends. (shrink)

In this paper, we introduce and defend the recurrent model for understanding bodily spatial phenomenology. While Longo, Azañón and Haggard (2010) propose a bottom-up model, Bermúdez (2017) emphasizes the top-down aspect of the information processing loop. We argue that both are only half of the story. Section 1 intro- duces what the issues are. Section 2 starts by explaining why the top- down, descending direction is necessary with the illustration from the ‘body-based tactile rescaling’ paradigm (de Vignemont, Ehrsson and Haggard, (...) 2005). It then argues that the bottom-up, ascending direction is also necessary, and substantiates this view with recent research on skin space and tactile field (Haggard et al., 2017). Section 3 discusses the model’s application to body ownership and bodily self-representation. Implications also extend to topics such as sense modality individuation (Macpherson, 2011), the constancy- based view of perception (Burge, 2010), and the perception/cognition divide (Firestone and Scholl, 2016).

Some sensory modalities, such as sight, touch and audition, are arguably spatial, and one way to understand these spatial senses is to investigate spatial representations in them. Here I focus on a specific element in this area— the interplay between perspectival variation and spatial constancy—and discuss recent interdisciplinary works on this topic. With these relevant experimental works, we will see clearly how traditional controversies in philosophy, for example, whether we perceive perspectival shapes as well as objective shapes, and whether any (...) sensory field should be postulated in senses other than vision, can benefit from considerations in empirical sciences.

ABSTRACT Issues concerning the putative perception/cognition divide are not only age-old, but also resurface in contemporary discussions in various forms. In this paper, I connect a relatively new debate concerning perceptual confidence to the perception/cognition divide. The term ‘perceptual confidence’ is quite common in the empirical literature, but there is an unsettled question about it, namely: are confidence assignments perceptual or post-perceptual? John Morrison in two recent papers puts forward the claim that confidence arises already at the level of perception. (...) In this paper, I first argue that Morrison’s case is unconvincing, and then develop one picture on perceptual precision with the notion of ‘matching profile’ and ‘supervaluation’ : 481–495.), highlighting the fact that this is a vagueness account, which is similar to but importantly different from indeterminacy accounts : 156–184.). With this model in hand, there can be rich resources with which to draw a theoretical line between perception and cognition. (shrink)

Freeman Dyson has questioned whether any conceivable experiment in the real universe can detect a single graviton. If not, is it meaningful to talk about gravitons as physical entities? We attempt to answer Dyson’s question and find it is possible concoct an idealized thought experiment capable of detecting one graviton; however, when anything remotely resembling realistic physics is taken into account, detection becomes impossible, indicating that Dyson’s conjecture is very likely true. We also point out several mistakes in the literature (...) dealing with graviton detection and production. (shrink)

There have recently been various empirical attempts to answer Molyneux’s question, for example, the experiments undertaken by the Held group. These studies, though intricate, have encountered some objections, for instance, from Schwenkler, who proposes two ways of improving the experiments. One is “to re-run [the] experiment with the stimulus objects made to move, and/or the subjects moved or permitted to move with respect to them” (p. 94), which would promote three dimensional or otherwise viewpoint-invariant representations. The other is “to use (...) geometrically simpler shapes, such as the cube and sphere in Molyneux’s original proposal, or planar figures instead of three-dimensional solids” (p. 188). Connolly argues against the first modification but agrees with the second. In this article, I argue that the second modification is also problematic (though still surmountable), and that both Schwenkler and Connolly are too optimistic about the prospect of addressing Molyneux’s question empirically.

This book brings together perspectives on predictive processing and expected experience. It features contributions from an interdisciplinary group of authors specializing in philosophy, psychology, cognitive science, and neuroscience. Predictive processing, or predictive coding, is the theory that the brain constantly minimizes the error of its predictions based on the sensory input it receives from the world. This process of prediction error minimization has numerous implications for different forms of conscious and perceptual experience. The chapters in this volume explore these implications (...) and various phenomenon related to them. The contributors tackle issues related to precision estimation, sensory prediction, probabilistic perception, and attention, as well as the role predictive processing plays in emotion, action, psychotic experience, anosognosia, and gut complex. Expected Experiences will be of interest to scholars and advanced students in philosophy, psychology, and cognitive science working on issues related to predictive processing and coding. (shrink)

In this short paper, I discuss certain aspects of a “common-sense” approach to truth and falsity. It is my experience that many will object to what I have to say. As you read, if you have objections, try to formulate them carefully, and ask yourself whether I attempt a reply.

This document collects natural derivation systems for logics described in Priest, An Introduction to Non-Classical Logic [4]. It provides an alternative or supplement to the semantic tableaux of his text. Except that some chapters are collapsed, there are sections for each chapter in Priest, with an additional, final section on quantified modal logic. In each case, (i) the language is briefly described and key semantic definitions stated, (ii) the derivation system is presented with a few examples given, and (iii) soundness (...) and completeness are proved. There should be enough detail to make the parts accessible to students would work through parallel sections of Priest. (shrink)

Recently, there is a renewed debate concerning the role of perspective in vision. Morales et al. (2020) present evidence that, in the case of viewing a rotated coin, the visual system is sensitive to what has often been called “perspectival shapes.” It has generated vigorous discussions, including an online symposium by Morales and Cohen, an exchange between Linton (2021) and Morales et al. (2021), and most recently, a fierce critique by Burge and Burge (2022), in which they launch various conceptual (...) and empirical objections. Although Morales and Firestone (2022) have responded to them recently, and we are in agreement with Morales and Firestone in general, there are further problems in Burge and Burge (2022) that are worth highlighting. The main point of this comment is that what the Burge–Burge team call “viewpoint-dependent relational properties” are simply instances of what the Morales–Firestone team call “perspectival shapes”; the confusion arises from Burge and Burge’s misconstrual of Morales et al.’s claims. This shows that conceptually, the two teams are in large agreement, as Morales and Firestone (2022) also point out, and the focus should be put on the empirical disagreements, which has been covered by Morales and Firestone (2022). Relatedly, we argue that Burge and Burge (2022) misinterpret Morales et al. (2020) as supporting a new entity in perception science, and that this misinterpretation is a primary source of their apparent disagreement. This is worth pointing out because such misunderstanding generates many unnecessary quarrels that hinder progress. (shrink)

The papers collected in this volume were originally presented at a sym posium held at the University of Pennsylvania in December of 1968. Each of the papers has been revised in light of the discussions that took place during this symposium. None of the papers has appeared in print previously. The extensive bibliography that appears at the end of the volume was originally distributed during the symposium and was revised on the basis of many helpful suggestions made by those who (...) participated. The symposium was made possible by a grant from The National Science Foundation and funds contributed by the Philosophy Depart ment of the University of Pennsylvania. On behalf of the contributors to this volume, I would like to express my thanks to these organizations for their generous support. In addition, I would like to express my gratitude to the members of the Graduate Philosophy Students Organization at the University of Penn sylvania for the considerable assistance they gave me during the sym posium. My thanks, also, to Judith Sofranko and Lynn Luckett for their very responsible efforts in the preparation of the manuscript. Finally, I would like to thank Professor James Cornman for his invaluable advice and encouragement. (shrink)

More than sixty reporters discuss ethical dilemmas facing the journalist and how they have personally coped with such problems as conflicts of interest, gifts, bribes, news leaks, and confidentiality of sources.

Aristotle’s views on time have received sporadic at tention over the years, but Ursula Coope’s elegantl y- written book is the first monograph available in En glish dedicated exclusively to the account that Ari stotle develops in the final five chapters of Physics IV. Three topics form the thematic core of the boo k: time’s relation to change, time’s status as a kind of numb er, and the unity and diversity of times. I shall t ouch on each of these (...) themes and indicate how I think Coope ’s interpretation fares. While I disagree with her reconstruction of the account on several central po ints, it exhibits a great deal of ingenuity and sophistication and deserves careful consideration. (shrink)

Involving as it does impossible worlds and the like, the Routley-Meyer worlds semantics for relevant logic has seemed unmotivated to some. I set a version of relevant semantics in a context to make sense of its different elements. Suppose a view which makes room for structured properties — or related entities which combine in arbitrary ways to form structured ones. Then it may seem natural to say entailment supervenes upon the structures, so that P entails Q just when part of (...) the condition for being p is being q. If P stands in this relation to Q, a result is that there is no possible world where P but not Q, so that P classically entails Q. But the conditions are not equivalent. For all possible worlds, but not all properties, are maximal and consistent. I suggest that relevant semantics is naturally seen as modeling entailment grounded in property structure and makes sense insofar as it reflects this fundamental and intuitive notion. (shrink)

In this letter we focus on the cognitive science of consciousness. The general message is that, while this interdisciplinary area has made much progress in recent years, there is a tendency of downplaying conceptual issues, and therefore underestimating the difficulties of various problems. We briefly focus on a few prominent examples only, due to the space limit, but the general message should be clear: this recent tendency can be problematic for the progress of the consciousness branch of cognitive sciences.

In 1925, David Katz published an influential monograph on touch, Der Aufbau der Tastwelt, which was translated into English in 1989. Although it is called “the world of touch,” it also discusses the thermal and the nociceptive senses, albeit briefly. In this chapter, we will follow this approach, but we will speak about “somatosensory senses” in general in order to remind ourselves that perceptions of temperatures and pains should also be considered together in this context.

In lieu of an abstract, here is a brief excerpt of the content:Being Sure of One's Self: Hume on Personal Identity1 Corliss Gayda Swain A number of papers recently published on Hume's theory of personal identityhavebeen devoted to the question: Whyin the Appendix to the Treatise did Hume express complete or acute dissatisfaction with his account of personal identity in book 1 of that work?2 In this paper I shall argue that no adequate answer can be given to this (...) question because its presupposition—namely, that Hume discovered some reason to be dissatisfied with his account—is false. My thesis is that Hume did not write the section ofthe Appendix dealing with personal identity in order to raise new questions about the adequacy ofhisbook 1 account of the mind; he wrote it in order to defend that account by showing that alternative explanations of personal identity are incoherent.3 Very briefly, this defense is as follows. In the Appendix Hume considers two hypotheses concerning the nature of the human mind: the first is the hypothesis accepted by many of the modern philosophers, namely, that the mind is a thinking substance which is both unitary and simple; the secondis Hume's own account ofpersonal identity, according to which "the true idea of the human mind, is to consider it as a system ofdifferent perceptions or different existences, which are link'd togetherby the relation ofcause and effect."4 Drawing on arguments he had developed in Treatise 1.4.5 and 6, Hume shows in the Appendix that the first hypothesis, while pretending to account for the identityand simplicityofthe selfin terms ofamental substance and to offer a new foundation for knowledge, actually leads us into the same labyrinth of obscurities and contradictions in which the ancient philosophy was involved when it tried to account for the identity and simplicity of material objects in terms of material substances. The modern philosophy tried to solve the same kind of problem as did the ancients, using the same kind of resources as the ancients used, and for this reason it is involved in the same contradictions and obscurities when it tries to explain the nature of the mind as the ancients were when they tried to explain the nature of matter. Hume's response to this situationisnotmerelytorejectbothmetaphysical systemsbutalso to reject their formulation of the problems ofidentity through change and unity in diversity and thè attendant criterion ofadequacy for the solution. Hume is sceptical that the problem which both the ancient Volume XVII Number 2 107 CORLISS GAYDA SWAIN andthemodernmetaphysicians setthemselves canbe solved,5but this does not mean that he is sceptical about personal identity or his own account ofit. In book 1 Hume had argued that a proper understanding ofthe real problem of personal identity leads to a real solution. In the Appendix he is concerned to show that this solution is not a solution to the (insoluble) problem that so preoccupied the metaphysicians. It is Hume's insistence that the metaphysicians' problem is insoluble that seems to have led commentators to think that Hume was dissatisfied with his own solution to the problem ofpersonal identity. On this view, the labyrinth ofcontradictions in which Hume finds himselfin the Appendix is not a labyrinth he gets into upon accepting his own account of personal identity, but rather a labyrinth he finds himself in without that account. What the Appendix adds to Hume's positive account of personal identity is a clear statement of the destructive argument againstmetaphysical systems that try to have it both ways. Thus, the Appendix should be read not as a renunciation but as a defense. I. Hume's "Renunciation" Commentators who hold that Hume found a new problem that was connected with his book 1 account of personal identity seem to have some strong textual support for their view.6 In the introductory paragraph of the section in the Appendix dealing with personal identity, Hume says, "But upon a more strict review of the section concerningpersonal identity, I find myselfinvoWd in such a labyrinth, that, I must confess, I neither know how to correct my former opinions, nor how to render them consistent" (T 633).7 He confesses that his account ofpersonal identity is "very defective" (T 635) and claims that...

While the prevalence of opioid use disorder among pregnant women has multiplied in the United States in the last decade, buprenorphine treatment for peripartum women with OUD has been administered to reduce risks of repeated cycles of craving and withdrawal. However, the maternal behavior and bonding in mothers with OUD may be altered as the underlying maternal behavior neurocircuit is opioid sensitive. In the regulation of rodent maternal behaviors such as licking and grooming, a series of opioid-sensitive brain regions are (...) functionally connected, including the ventral pallidum. In humans, these brain regions, interact with the supplementary motor area to regulate maternal behaviors and are functionally dysregulated by opioids. It is unclear how these brain regions respond to the emotions of their child for mothers receiving BT. In this functional magnetic resonance imaging pilot study in 22 mothers within the first postpartum year, including six mothers receiving BT and 16 non-OUD mothers as a comparison group, we devised a child face mirroring task in fMRI settings to assess maternal responses to pictures of facial expressions of own child and an unknown child in an empathic mirroring condition and a non-mirroring observation condition. In each condition, faces of neutral, ambiguous, distressed, and joyful expressions of each child were repeatedly displayed in a random order. The response of SMA during empathic mirroring vs. non-mirroring of own child was reduced among BT/OUD vs. CG. Within MBN, the left VP, critical for parental sensitivity, had a similar deficit. This study outlines potential mechanisms for investigating the risks of deficits in the neural responses to actual maternal sensitivity and parenting behavior in mothers with OUD, and potential targets for interventions that reduce stress and augment maternal behavior and child outcome.

In this talk, we defend extended cognition against several criticisms. We argue that extended cognition does not derive from armchair theorizing and that it neither ignores the results of the neural sciences, nor minimizes the importance of the brain in the production of intelligent behavior. We also argue that explanatory success in the cognitive sciences does not depend on localist or reductionist methodologies; part of our argument for this is a defense of what might be called ‘holistic science’.

The topic of this paper is the complex interaction between attention, fixation, and one species of change blindness. The two main interpretations of the target phenomenon are the ‘blindness’ interpretation and the ‘inaccessibility’ interpretation. These correspond to the sparse view (Dennett 1991; Tye, 2007) and the rich view (Dretske 2007; Block, 2007a, 2007b) of visual consciousness respectively. Here I focus on the debate between Fred Dretske and Michael Tye. Section 1 describes the target phenomenon and the dialectics it entails. Section (...) 2 explains how attention and fixation weigh in these debates, and argues that Dretske’s hyper-rich view fails precisely because he overlooks certain effects of attention and fixation. Section 3 explains why Tye’s view is also unsatisfying, mainly because he misconceives the degree of access. Section 4 then puts forward the positive model covariance, which has it that the degree of cognitive access tracks the degree of phenomenology, and contrasts it with Block’s view on the Sperling iconic memory paradigm. The paper ends with a discussion of levels of seeing, which involve crowding, indexing, and other visual phenomena. Change ‘blindness’ is a set of phenomena that was discovered about two decades ago, yet an entirely satisfying understanding is still lacking. To move forward, a more detailed understanding of attention and fixation is called for. (shrink)

In None so Fit to Break the Chains Dan Swain offers an interpretation of Marx's ethics that foregrounds his commitment to working class self-emancipation and uses it as a guiding thread to interpret a number of different aspects of Marx's ethical thought. This commitment is frequently overlooked in discussions of Marx's ethics, but it deeply influenced his criticism of capitalism, his approach towards an alternative, and his conception of his own role as activist and theorist. Foregrounding self-emancipation offers new (...) perspectives on various existing debates in the interpretation of Marx, such as the meanings of concepts like alienation, exploitation and utopianism, and can also offer insights into broader questions of the relationship between critical theory and practice.

Individuals use their capacity for autonomy to express preferences regarding food choices. Food choices are fundamental, universal, and reflect a diversity of interests and cultural preferences. Traditionally, autonomy is cast in only epistemic terms, and the social and political dimension of it, where autonomy obstruction tends to arise, is omitted. This reflects problematic limits in the Cartesian notion of the individual. Because this notion ignores context and embodiment, the external and internal constraints on autonomy that extend from social location are (...) not considered. Therefore, reconceptions of the individual and autonomy which emphasize social location and relational interdependency are needed. To combat autonomy obstruction, individuals can appeal to community and community autonomy as a social mechanism. Communities are social groups characterized by people living in places with shared goals. Recognizing their interdependency, individuals can organize as communities in order to accomplish objectives that they cannot on their own. While community autonomy is valuable unto itself, it can also enhance individual autonomy. (shrink)

This paper investigates the complicated relations between various versions of naturalism, behaviorism, and mentalism within the framework of W. V. O. Quine's thinking. It begins with Roger Gibson's reconstruction of Quine's behaviorisms and argues that it lacks a crucial ontological element and misconstrues the relation between philosophy and science. After getting clear of Quine's naturalism, the paper distinguishes between evidential, methodological, and ontological behaviorisms. The evidential and methodological versions are often conflated, but they need to be clearly distinguished in order (...) to see whether Quine's argument against mentalism is cogent. The paper argues that Quine's naturalism supports only the weakest version of behaviorism, that is, the evidential one, but this version is compatible with mentalistic semantics. Quine's opposition to mentalism is an overreaction from the behaviorist camp. By contrast, Jerry Fodor's objection to Jose Luis Bermudez is an overreaction from the opposite direction. (shrink)

In her essay --?Information, Perception and Action--, Claire Michaels reaches two conclusions that run very much against the grain of ecological psychology. First, she claims that affordances are not perceived, but simply acted upon; second, because of this, perception and action ought to be conceived separately. These conclusions are based upon a misinterpretation of empirical evidence which is, in turn, based upon a conflation of two proper objects of perception: objectively with properties and affordances.

The historical Molyneux’s question – roughly, whether congenital blind subjects can visually identify shapes in front of them right after being made to see – is having its renaissance in recent years (Ferretti and Glenney, 2021). While there have been many different formulations of it, and many attempted answers as well, no clear consensus has been reached. Moreover, although arguably both memory and imagination are involved in the process, their roles in the Molyneux’s task have not been adequately discussed. In (...) this paper, I focus on a specific version of Molyneux’s question, propose a specific hypothesis in relation to that version, and sketch the roles of structural correspondence, memory, and imagination in the relevant hypothesis. One key moral of this discussion is that while Molyneux’s question has primarily been regarded as a perceptual puzzle, other kinds of mental episodes such as memory and imagination have to be taken into account as well in order to have a more satisfying answer to versions of Molyneux’s question (Macpherson and Dorsch, 2018).

In the present article, I attempt to relate Saul Kripke's “sceptical paradox” to some issues about the self; specifically, the relation between the self and its mental states and episodes. I start with a brief reconstruction of the paradox, and venture to argue that it relies crucially on a Cartesian model of the self: the sceptic regards the Wittgensteinian “infinite regress of interpretation” as the foundation of his challenge, and this is where he commits the crucial mistake. After the diagnosis, (...) I attempt to sketch my own model of the self and its mental states and episodes. This tentative picture binds meaning and the self together, stressing the subjective aspect of meaning without committing the same fallacy. The solution ventured here is relatively independent of the secondary literatures on the sceptical paradox of following rules, for it aims to provide a new angle to understand and meet the challenge presented by the sceptic.

This paper develops the situational model of primate beliefs from the Prior-Lurz line of thought. There is a strong skepticism concerning primate beliefs in the analytic tradition which holds that beliefs have to be propositional and non-human animals do not have them. The response offered in this paper is twofold. First, two arguments against the propositional model as applied to other animals are put forward: an a priori argument from referential opacity and an empirical argument from varieties of working memory. (...) Second, the Prior-Lurz situational model based on state of affairs as opposed to propositions is introduced and defended with two significant modifications. With this model of primate beliefs we can make progress in understanding how other primates can have certain mindreading capacity. (shrink)

This is a précis of my recent monograph John McDowell on Worldly Subjectivity: Oxford Kantianism Meets Phenomenology and Cognitive Sciences. I first describe the key question the book is trying to answer via understanding McDowell’s thinking and the general outline of it. The key question is a Kantian how-possible question, and the outline includes the distinction between first and second nature, the contrast between Cogito and Homo sapience, and how a minded human animal can be a perceiver, knower, thinker, speaker, (...) agent, person, and conceptual cum self-conscious being in the world. I then focus on two key notions of the subtitles—phenomenology and cognitive sciences—and explain how they figure in the text. After that, a chapter-by-chapter summary is provided, albeit selectively. This introductory piece ends with a prediction that McDowell’s works will still be widely discussed in the reasonable distant future. (shrink)

Timothy Williamson’s Knowledge and its Limits has been highly influential since the beginning of this century. It can be read as a systematic response to scepticism. One of the most important notions in this response is the notion of «evidence,» which will be the focus of the present paper. I attempt to show primarily two things. First, the notion of evidence invoked by Williamson does not address the sceptical worry: he stipulates an objective notion of evidence, but this begs the (...) question against his opponent. Second, his related thesis «Evidence equals Knowledge» does not sit well with his own content externalism: he promises to relate epistemology to philosophy of mind, but he fails to live up to this commitment in his crucial chapter on scepticism. Other minor problems concerning evidence will also be discussed in due course. (shrink)

The term “consciousness” is very often, though not always, interchangeable with the term “awareness,” which is more colloquial to many ears. We say things like “are you aware that ...” often. Sometimes we say “have you noticed that ... ?” to express similar thoughts, and this indicates a close connection between consciousness (awareness) and attention (noticing), which we will come back to later in this chapter. Ned Block, one of the key figures in this area, provides a useful characterization of (...) what he calls “phenomenal consciousness.” For him, phenomenal consciousness is experience. Experience covers perceptions, e.g., when we see, hear, touch, smell, and taste, we typically have experiences, such as seeing colors and smelling odors. It also covers bodily awareness, e.g., we typically have experiences of our own bodily temperature and positions of limbs. Consciousness is primarily about this experiential aspect of our mental lives. (shrink)

Rowlands’s case for attributing personhood to lower animals is ultimately convincing, but along the way he fails to highlight several distinctions that are crucial for his argument: Personhood vs. personal identity; the first person vs. its mental episodes; and pre- reflective awareness in general vs. one specific case of it.

In this paper I defend a pluralistic approach in understanding function, both in biological and other contexts. Talks about function are ubiquitous and crucial in biology, and it might be the key to bridge the “manifest image” and the “scientific image” identified by Sellars (1962). However, analysis of function has proven to be extremely difficult. The major puzzle is to make sense of “time-reversed causality”: how can property P be the cause of its realizer R? For example, “pumping blood” is (...) a property of hearts, but a property of hearts cannot be the cause of the presence of hearts, since properties cannot predate their realizers and be causes of them. In section 2 I discuss Wright’s etiological analysis, Cummins’ causal-role analysis, and their critics. In section 3 I defend a version of the “consensus without unity” strategy proposed by Godfrey-Smith from Christopher Boorse’s recent critique (2002). In Section 4 I conclude by reflecting on the relation between functional discourses and physicalism. (shrink)
