Chris Frith’s target chapters contain a wealth of interesting experiments and striking theoretical claims. In these comments I begin by drawing out some of the key themes in his discussion of action and the sense of agency. Frith’s central claim about conscious action is that what we are primarily conscious of in acting is our own agency. I will review some of the experimental evidence that he interprets in support of this claim and then explore the following three questions (...) about the awareness of agency: Should we locate the phenomena that Frith describes as awareness of agency at the personal level or at the subpersonal level? If we are indeed operating at the personal level, then should we think about awareness of agency as something we experience, or as something that we believe? If awareness of agency is to be understood experientially, is there what some authors have called “a sense of agency”, where this is understood to be a distinctive type of experience that accompanies agentive behaviors but is absent in behaviors that are not under the control of the agent? In what follows I argue that awareness of agency should be located at the personal level, and that we should think of it as something we experience. But I will reject the claim that there is a distinctive sense of agency. (shrink)

The author challenges the view that birth cannot be a morally relevant fact in the process of development from zygote to child. He reviews specific arguments against giving any moral significance to the fact of birth. Drawing on recent work in developmental psychology, he contends that the lives of neonates can have a level of self-consciousness that confers moral significance but can only be possessed after birth. He shows that the position he has argued for provides a framework within which (...) the move from the moral validity of aborting sentient fetuses to the moral validity of infanticide might be resisted. He concludes that arguments suggesting that birth can be morally significant support the view that the acquisition of moral significance is a gradual and multilayered phenomenon. (shrink)

Debates about bodily ownership and psychological ownership have typically proceeded independently of each other. This paper explores the relation between them, with particular reference to how each is illuminated by psychopathology. I propose a general framework for studying ownership that is applicable both to bodily ownership and psychological ownership. The framework proposes studying ownership by starting with explicit judgments of ownership and then exploring the bases for those judgments. Section 3 discusses John Campbell’s account of ψ-ownership in the light of (...) that general framework, emphasizing in particular his fractionation of ψ-ownership into two dissociable components. Section 4 briefly presents an account of φ-ownership that I have developed in more detail elsewhere. Section 5 explores the suggestion, originating with Alexandre Billon, that there needs to be an integrated account of φ-ownership and ψ-ownership because depersonalization disorders typically involve breakdowns of both φ-ownership and ψ-ownership. The argument from depersonalization is not compelling, but Section 6 proposes a different way of reaching the same conclusion. Section 7 shows how reflecting on agency and practical reasoning offers a common thread between the models of φ-ownership and ψ-ownership discussed earlier in the paper. (shrink)

What is the relation between philosophical theorizing and experimental data? A modest set of naturalistic assumptions leads to what I term the force-field puzzle. The assumption that philosophy is continuous with natural science, as captured in Quine’s force-field metaphor, seems to push us simultaneously towards thinking that there have to be conceptual constraints upon how we interpret experimental data and towards thinking that there cannot be such conceptual constraints, because all theorizing must be accountable to data and observation. The key (...) to resolving the force-field puzzle is to take a more nuanced view of how conceptual constraints can be accountable to data and observation. This can be done by developing conceptual arguments in conjunction with interpretative frameworks for making sense of experimental evidence. This paper shows how attending to important differences between different types of mindreading yields tools for interpreting experimental and observational data in a manner consistent with a (conceptually derived) constraint that I have developed elsewhere. This is the first-order constraint that second-order thinking, or thinking about thinking, is only available to language-using creatures. (shrink)

Victor Verdejo’s paper ‘On Having the Same First Person Thoughts’ introduces an interesting and fruitful framework for applying the type-token distinction to first person thoughts. He draws a three-way distinction between types, instantiable types, and instantiated types, and uses that distinction to open up a conceptual space for the possibility of shareable first person thoughts. This note distinguishes two types of interpersonal shareability and argues that Verdejo’s suggestions about instantiable types can only secure shareability of the first kind, but not (...) the second. The author then shows how his own account of what he terms the token-sense of “I” succeeds in making possible this second type of interpersonal shareability, despite the criticisms in Verdejo’s paper.

A number of authors have noted that the key steps in Fitch’s argument are not intuitionistically valid, and some have proposed this as a reason for an anti-realist to accept intuitionistic logic (e.g. Williamson 1982, 1988). This line of reasoning rests upon two assumptions. The first is that the premises of Fitch’s argument make sense from an anti-realist point of view – and in particular, that an anti-realist can and should maintain the principle that all truths are knowable. The second (...) is that we have some independent reason for thinking that classical logic is not appropriate in this area. This paper explores these two assumptions in the context of Michael Dummett’s version of anti-realism, with particular reference to the argument from indefinite extensibility developed at various points in Dummett’s writings (e.g. Dummett 1991 Ch. 24). -/- Dummett argues that certain concepts, the indefinitely extensible concepts, are such that we cannot form a clear and determinate conception of all the objects that fall under them. The most familiar examples of indefinitely extensible concepts are mathematical. Dummett discusses the concepts ordinal number, real number, and natural number, which are indefinitely extensible because any conception that one might form of their complete extension can be extended to a more inclusive conception (as, for example, in Cantor’s proof of the non-denumerability of the set of real numbers). This paper argues that the concept of a truth is indefinitely extensible. This gives a Dummettian anti-realist an independent motivation for rejecting the classical understanding of the quantifiers in this area. At the same time, however, it places in doubt the admissibility of the knowability principle, which seems to involve quantification over the “totality” of truths. As Dummett is at pains to point out (1991: 316), some sentences that purport to quantify over the extension of an indefinitely extensible concept plainly have a truth-value (we can truly say, for example, that every ordinal number has a successor, even though when we say that we are not quantifying over the set of all ordinals). But is the knowability principle one of these sentences? (shrink)

"The book presents in accessible fashion recent important work on the self and self-consciousness and also moves the issues forward with interesting new ideas. It provides a notably crisp and clear treatment of some extremely intriguing topics." -- Jane Heal, Department of Philosophy, University of Cambridge In this book, José Luis Bermú dez addesses two fundamental problems in the philosophy and psychology of self-consciousness: (1) Can we provide a noncircular account of fully fledged self-conscious thought and language in (...) terms of more fundamental capacities? (2) Can we explain how fully fledged self-conscious thought and language can arise in the normal course of human development? Bermú dez argues that a paradox (the paradox of self-consciousness) arises from the apparent strict interdependence between self-conscious thought and linguistic self-reference. The paradox renders circular all theories that define self-consciousness in terms of linguistic mastery of the first-person pronoun. It seems to follow from the paradox of self-consciousness that no such account or explanation can be given. Drawing on recent work in empirical psychology and philosophy, the author argues that any explanation of fully fledged self-consciousness that answers these two questions requires attention to primitive forms of self-consciousness that are prelinguistic and preconceptual. Such primitive forms of self-consciousness are to be found in somatic proprioception, the structure of exteroceptive perception, and prelinguistic forms of social interaction. The author uses these primitive forms of self-consciousness to dissolve the paradox ofself-consciousness and to show how the two questions can be given an affirmative answer. (shrink)

Cognitive Science combines the interdisciplinary streams of cognitive science into a unified narrative in an all-encompassing introduction to the field. This text presents cognitive science as a discipline in its own right, and teaches students to apply the techniques and theories of the cognitive scientist's 'toolkit' - the vast range of methods and tools that cognitive scientists use to study the mind. Thematically organized, rather than by separate disciplines, Cognitive Science underscores the problems and solutions of cognitive science, rather than (...) those of the subjects that contribute to it - psychology, neuroscience, linguistics, etc. The generous use of examples, illustrations, and applications demonstrates how theory is applied to unlock the mysteries of the human mind. Drawing upon cutting-edge research, the text has been updated and enhanced to incorporate new studies and key experiments since the first edition. A new chapter on consciousness has also been added.

It is now 25 years since Gareth Evans introduced the distinction between conceptual and nonconceptual content in The Varieties of Reference. This is a fitting time to take stock of what has become a complex and extended debate both within philosophy and at the interface between philosophy and psychology. Unfortunately, the debate has become increasingly murky as it has become increasingly ramified. Much of the contemporary discussion does not do full justice to the powerful theoretical tool originally proposed by Evans (...) and subsequently refined by theorists in the late 1980’s and early 1990’s – most effectively, I think, by Christopher Peacocke (particularly in his 1992). Even worse, significant parts of the discussion are somewhat confused. This paper makes a start on clarifying what I think ought to be the central issues in debates about nonconceptual content. I begin in §1 by pointing out how narrowly focused contemporary discussion is relative to Evans’s original discussion. We are not making as much use as we should of nonconceptual content as a tool for understanding subpersonal information processing and the complexities of its status relative to perception and thought at the personal level. In §2 I turn to what is the central focus of contemporary discussion, namely, the content of perception and identify a “master argument” for nonconceptualism based on the relation between conceptual capacities and capacities for perceptual discrimination. The aim of §3 is to clarify the relation between the claim that perception has nonconceptual content and some superficially similar claims discussed by philosophers of perception. Finally, in §4 I explain why the attention recently focused on what is sometimes called the state version of the nonconceptualist thesis seems to me to be misdirected. (shrink)

In a recent paper, Fredérique de Vignemont has argued that there is a positive quale of bodily ownership . She thinks that tactile and other forms of somatosensory phenomenology incorporate a distinctive feeling of myness and takes issue with my defense in Bermúdez of a deflationary approach to bodily ownership. That paper proposed an argument deriving from Elizabeth Anscombe’s various discussions of what she terms knowledge without observation . De Vignemont is not convinced and appeals to the Rubber Hand (...) Illusion to undercut my appeal to Anscombe. Section 1 of this article restates the case against the putative quale of ownership. Section 2 explains why de Vignemonts’ objections miss the mark. Section 3 discusses in more detail how to draw a principled distinction between bodily awareness and ordinary perceptual awareness.

Frames and framing make one dimension of a decision problem particularly salient. In the simplest case, framesprimeresponses (as in, e.g., the Asian disease paradigm, where the gain frame primes risk-aversion and the loss frame primes risk-seeking). But in more complicated situations frames can function reflectively, by making salient particular reason-giving aspects of a thing, outcome, or action. For Shakespeare's Macbeth, for example, his feudal commitments are salient in one frame, while downplayed in another in favor of his personal ambition. The (...) role of frames in reasoning can give rise torational framing effects. Macbeth can prefer fulfilling his feudal duty to murdering the king, while also preferring bravely taking the throne to fulfilling his feudal duty, knowing full well that bravely taking the throne just is murdering the king. Such patterns ofquasi-cyclicalpreferences can be correct and appropriate from the normative perspective of how one ought to reason. The paper explores three less dramatic types of rational framing effects: (1) Consciously framing and reframing long-term goals and short-term temptations can be important tools for self-control. (2) In the prototypical social interactions modeled by game theory, allowing for rational framing effects solves longstanding problems, such as the equilibrium selection problem and explaining the appeal of non-equilibrium solutions (e.g., the cooperative solution in the Prisoner's Dilemma). (3) Processes for resolving interpersonal conflicts and breaking discursive deadlock, because they involve internalizing multiple and incompatible ways of framing actions and outcomes, in effect create rational framing effects.

Forms of thinking that involve thinking about thought are only available to creatures participating in a public language. Thoughts can only be the objects of further thoughts if they have suitable vehicle and the only suitable vehicle is public language sentences. These language-dependent cognitive abilities range from second-order reflection on one's own beliefs and desires and the capacity to attribute thoughts to others to the ability to entertain tensed thoughts and to deploy logical concepts. Many of these language-dependent cognitive abilities, (...) however, have primitive analogues that do not involve intentional ascent and hence are available at the nonlinguistic level. This chapter considers the practical implications this has for the scope and limits of nonlinguistic thought. The chapter explores the question: what types of thinking are in principle unavailable to nonlinguistic creatures? There are two types of intentional ascent, which might be termed explicit and implicit intentional ascent respectively. (shrink)

This article evaluates the following four theses about bodily experience and self-consciousness: Descartes's thesis ; Kant's thesis ; Locke's thesis ; and Merleau-Ponty's thesis. I argue that they are all true.

This commentary defends intentionalist accounts of self-deception against Mele by arguing that: (1) viewing self-deception on the model of other-deception is not as paradoxical as Mele makes out; (2) the paradoxes are not entailed by the view that self-deception is intentional; and (3) there are two problems for Mele's theory that only an intentionalist theory can solve.

Marko Jurjako’s article “Self-deception and the selectivity problem” (Jurjako 2013) offers a very interesting discussion of intentionalist approaches to self-deception and in particular the selectivity objection to anti-intentionalism raised in Bermúdez 1997 and 2000. This note responds to Jurjako’s claim that intentionalist models of self-deception face their own version of the selectivity problem, offering an account of how intentions are formed that can explain the selectivity of self-deception, even in the “common or garden” cases that Jurjako emphasizes.

The idea that thoughts are structured is essential to Frege's understanding of thoughts. A basic tenet of his thinking was that the structure of a sentence can serve as a model for the structure of a thought. Recent commentators have, however, identified tensions between that principle and certain other doctrines Frege held about thoughts. This paper suggests that the tensions identified by Dummett and Bell are not really tensions at all. In establishing the case against Dummett and Bell the paper (...) argues (a) that Frege was committed, in virtue of his doctrine of decomposition, to the thesis that a single sentence can express a range of thoughts, and (b) that Frege was committed, in virtue of his views about truth, to the thesis that a single thought can be expressed by structurally different sentences. But neither of these theses comes into conflict with the basic principle. (shrink)

This chapter explains how a theorist might fix an ontology in a way that will allow the theorist to determine what objects a particular non-language-using creature is capable of thinking about—or, in other words, that will elucidate how the creature “carves up” its world into bounded individuals. Among other issues, it explores a version of successful semantics based on the idea that the content of a belief is its utility condition and the content of a desire its satisfaction-condition. Existing versions (...) of success semantics generate a significant problem of indeterminacy. Success semantics originated with some fleeting comments by Frank Ramsey about the beliefs of a chicken in his 1927 article ‘Facts and Propositions’. He commented that the chicken's belief that a certain type of caterpillar is poisonous should be equated with the chicken's abstaining from eating such caterpillars on account of unpleasant experiences connected with them.

In Bermúdez 2013 I argued against David Lewis’s well-known and widely accepted claim that Newcomb’s problem and the prisoner’s dilemma are really notational variants of a single problem. Mark Walker’s paper in this journal takes issue with my argument. In this note I show how Walker’s criticisms are misplaced. The problems with Walker’s argument point to more general and independently interesting conclusions about, first, the relation between deliberation and decision and, second, the differences between the prisoner’s dilemma, which is (...) a strategic choice problem, and Newcomb’s problem, which is a parametric choice problem.

This paper considers how best an eliminativist might argue for the radical falsity of commonsense psychology. I will be arguing that Paul Churchland’s “official” arguments for eliminative materialism (in, e.g., Churchland 1981) are unsatisfactory, although much of the paper will be developing themes that are clearly present in Churchland’s writings. The eliminativist needs to argue that the representations that feed into action are fundamentally different from those invoked by propositional attitude psychology. The “springs of action” are representations of features that (...) are much more finely grained than those encoded within the vocabulary that we employ to specify the content of propositional attitudes. The eliminativist’s most promising strategy is to argue that, whatever we might think about why we behave the way we do, careful experimental work will show that we are in fact acting in virtue of representations of properties and microfeatures that fall completely outside the ambit of propositional attitude psychology. The paper considers a number of examples of how this eliminativist strategy might be developed, ranging from the implications of the two visual systems hypothesis to research in social psychology into the role that situational factors play in controlling action.

This paper explores the relation between two ways of thinking about the sources of self-consciousness. We can think about the sources of self-consciousness either in genetic terms (as the origins or precursors of self-conscious thoughts) or in epistemic terms (as the grounds of self-conscious judgements). Using Christopher Peacocke's account of self-conscious judgements in Being Known as a foil, this paper brings out some important ways in which we need to draw upon the sources of self-consciousness in the genetic sense for (...) a proper understanding of the sources of self-consciousness in the epistemic sense.

According to David Lewis, the prisoner's dilemma (PD) and Newcomb's problem (NP) are really just one dilemma in two different forms (Lewis 1979). Lewis's argument for this conclusion is ingenious and has been widely accepted. However, it is flawed. As this paper shows, the considerations that Lewis brings to bear to show that the game he starts with is an NP equally show that the game is not a PD.

This paper explores Kornblith's proposal in "Knowledge and its Place in Nature" that knowledge is a natural kind that can be elucidated and understood in scientific terms. Central to Kornblith's development of this proposal is the claim that there is a single category of unreflective knowledge that is studied by cognitive ethologists and is the proper province of epistemology. This claim is challenged on the grounds that even unreflective knowledge in language-using humans reflects forms of logical reasoning that are in (...) principle unavailable to nonlinguistic animals.

Thought, Reference, and Experience is a collection of important new essays on topics at the intersection of philosophy of language, philosophy of mind, and philosophical logic. The starting-point for the papers is the brilliant work of the British philosopher Gareth Evans before his untimely death in 1980 at the age of 34. Evans's work on reference and singular thought transformed the Fregean approach to the philosophy of thought and language, showing how seemingly technical issues in philosophical semantics are inextricably linked (...) to fundamental questions about the structure of our thinking about ourselves and about the world. The papers, all newly written for this volume, explore different aspects of Evans's philosophical legacy, showing its importance to central areas in contemporary analytic philosophy. The volume includes a substantial introduction that introduces the principal themes in Evans's thought and places the papers in context. (shrink)

In this paper I explore a justification for transcendental idealism that emerges from the dialogue with philosophical scepticism in which Kant is on and off engaged throughout the Critique of Pure Reason. Many commentators, most prominently Strawson, have claimed that transcend‐ ental idealism is an unfortunate addition to the Critique, one that can profitably be excised in the interests of clarity and coherence. Against this general picture I urge that transcendental idealism is in fact a very natural consequence of some (...) of the central doctrines of the Critical Philosophy. It is in the context of Kant's debate with scepticism that this emerges most clearly. Nonetheless, I argue that Kant's employment of transcendental idealism against the sceptic is seriously compromised by his postulating the existence of unknowable things‐in‐themselves. As long as he maintains that there are unknowable things‐in‐themselves which are responsible for our having the experience that we do have, his position seems to collapse into sceptical idealism. In the final section of the paper I suggest that the only possible escape from this difficulty would be to rule out the possibility of affirming that unknowable things‐in‐themselves exist. I also suggest that an argument to this effect exists in the Critique and that Kant's position would be more consistent had he adhered to it. (shrink)

This chapter examines two theories related to the human character. It explores the differing responses to the questions of psychological explanations of the behavior of nonlinguistic creatures given by the two approaches to the nature of thought outlined earlier, and shows how neither can provide a fully satisfying account of thinking without words. They are Ferge's conception of thoughts as the senses of sentences and Fodor's language of thought hypothesis to the effect that thinking should be understood in terms of (...) the operation of sentence-like formulae in an internal language of thought. Both approaches start off from a single basic assumption, which is that the nature of thought can best be analyzed through the nature of language, but each approach takes a very different view of the essence of language. The chapter reveals Ferge's greater interest in mathematical thoughts than in those expressible by means of a natural language. (shrink)

This commentary discusses Pylyshyn's model of perceptual processing in the light of the philosophical distinction between the conceptual and the nonconceptual content of perception. Pylyshyn's processing distinction maps onto an important distinction in the phenomenology of visual perception.

This paper assesses Fodor’s well-known argument from multiple realizability to nonreductive physicalism. Recent work has brought out that the empirical case for cross-species multiple realizability is weak at best and so we consider whether the argument can be rebooted using a “thin” notion of intraspecies multiple realizability, taking individual neural firing patterns to be the realizers of mental events. We agree that there are no prospects for reducing mental events to individual neural firing patterns. But there are more plausible candidates (...) for the neural realizers of mental events out there, namely, global neural properties such as the average firing rates of neural populations, or the local field potential. The problem for Fodor’s argument is that those global neural properties point towards reductive versions of physicalism. (shrink)

Galen Strawson's keynote paper offers us one way of modelling the self, one that starts from the phenomenology of the sense of self and derives from that metaphysical conclusions about the nature of the self. Strawson is surely correct to hold that phenomenological considerations cannot be ignored in thinking about the metaphysics of the self. I am not as convinced as he is, however, that phenomenology is the royal road to metaphysics. What I want to sketch out in this short (...) paper is another approach to the metaphysics of the self, one that is driven by reductivist concerns. As far as I can see it is an open question whether there are any global points of disagreement between us. (shrink)

Peter Menzies has developed a novel version of the exclusion principle that he claims to be compatible with the possibility of mental causation. Menzies proposes to frame the exclusion principle in terms of a difference-making account of causation, understood in counterfactual terms. His new exclusion principle appears in two formulations: upwards exclusion — which is the familiar case in which a realizing event causally excludes the event that it realizes — and, more interestingly, downward exclusion, in which an event causally (...) excludes its realizer. This paper shows that one consequence of Menzies’s proposed solution to the problem of mental causation is a ubiquitous violation of the principle of closure — a fact that forces him into a trilemma to which we see no satisfactory response.

Many philosophers and game theorists have been struck by the thought that the backward induction argument (BIA) for the finite iterated pris- oner’s dilemma (FIPD) recommends a course of action which is grossly counter-intuitive and certainly contrary to the way in which people behave in real-life FIPD-situations (Luce and Raiffa 1957, Pettit and Sugden 1989, Bovens 1997).1 Yet the backwards induction argument puts itself forward as binding upon rational agents. What are we to conclude from this? Is it that people (...) in real-life FIPD-situations tend to act irrationally and that our own intuitions about what to do in such situations reveal us to be irra- tional? Alternatively, should we abandon game theory and decision theory as a guide to rationality? Or are there other ways in which the apparent disparity between the dictates of rationality and the reality of reasoning can be accommodated? (shrink)

Against Clarke and Beck's proposal that the approximate number system represents natural and rational numbers, I suggest that the experimental evidence is better accommodated by the thesis that the ANS represents cardinality comparisons. Cardinality comparisons do not stand in arithmetical relations and being able to apply them does not involve basic arithmetical concepts and operations.
