Skyrms, building on the work of Dretske, has recently developed a novel information-theoretic account of propositional content in simple signalling systems. Information-theoretic accounts of content traditionally struggle to accommodate the possibility of misrepresentation, and I show that Skyrms’s account is no exception. I proceed to argue, however, that a modified version of Skyrms’s account can overcome this problem. On my proposed account, the propositional content of a signal is determined not by the information that it actually carries, but by the (...) information that it would carry at the nearest separating equilibrium of the underlying evolutionary dynamics. I show that this amended account yields reasonable ascriptions of false propositional content in a well-known formal model of the evolution of communication , and close with a discussion of the serious but perhaps not insuperable difficulties we face in applying the account to examples of signalling in the real world.

The main thesis of this paper is twofold. In the first half of the paper, (§§1-2), I argue that there are two notions of mental representation, which I call objective and subjective. In the second part (§§3-7), I argue that this casts familiar tracking theories of mental representation as incomplete: while it is clear how they might account for objective representation, they at least require supplementation to account for subjective representation.

On a currently popular reading of Locke, an idea represents its cause, or what God intended to be its cause. Against Martha Bolton and my former self (among others), I argue that Locke cannot hold such a view, since it sins against his epistemology and theory of abstraction. I argue that Locke is committed to a resemblance theory of representation, with the result that ideas of secondary qualities are not representations.

The Hypothesis of Extended Cognition (HEC)—that many cognitive processes are carried out by a hybrid coalition of neural, bodily and environmental factors—entails that the intentional states that are reasons for action might best be ascribed to wider entities of which individual persons are only parts. I look at different kinds of extended cognition and agency, exploring their consequences for concerns about the moral agency and personal responsibility of such extended entities. Can extended entities be moral agents and bear responsibility for (...) actions, in addition to or in place of the individuals typically held responsible? What does it mean to be autonomous when one’s cognition is influenced and supported by a milieu of environmental factors? To answer these questions, I explore strong parallels between HEC’s critique of individualism in cognition, and feminist critiques of individualist accounts of self, agency, and autonomy. This relational and social conception of autonomous agency, as scaffolded and supported (or undermined and impaired) by a milieu of social, relational, and normative factors, has important lessons for HEC. Drawing together these two visions of distributed and decentralized aspects of personhood highlights how cognition, action, and responsibility are inextricably linked. It also encourages a reconceptualization of all cognition and all concerns about responsibility for actions, not simply as sometimes extended around individuals, but as fundamentally communal, social, and normative, with individual cognition and individual moral responsibility being derivative special cases, not the paradigm examples. Individuals are merely one of many possible loci of cognition, action, and responsibility. (shrink)

Causal theories of mental content attempt to explain how thoughts can be about things. They attempt to explain how one can think about, for example, dogs. These theories begin with the idea that there are mental representations and that thoughts are meaningful in virtue of a causal connection between a mental representation and some part of the world that is represented. In other words, the point of departure for these theories is that thoughts of dogs are about dogs because dogs (...) cause the mental representations of dogs. (shrink)

This book contains a representationalist theory of self-consciousness and of the phenomenal first-person perspective. It draws on empirical data from the cognitive and neurosciences.

We review some of the work already done around the notion of phenomenal intentionality and propose a way of turning this body of work into a self-conscious research program for understanding intentionality.

I aim to stand the received view about verificationism on its head. It is commonly thought that verificationism is a powerful philosophical tool, which we could deploy very effectively if only it weren’t so hopelessly implausible. On the contrary, I argue. Verificationism - if properly construed - may well be true. But its philosophical applications are chimerical.

I defend a theory of mental representation that satisfies naturalistic constraints. Briefly, we begin by distinguishing (i) what makes something a representation from (ii) given that a thing is a representation, what determines what it represents. Representations are states of biological organisms, so we should expect a unified theoretical framework for explaining both what it is to be a representation as well as what it is to be a heart or a kidney. I follow Millikan in explaining (i) in terms (...) of teleofunction, explicated in terms of natural selection. -/- To explain (ii), we begin by recognizing that representational states do not have content, that is, they are neither true nor false except insofar as they both “point to” or “refer” to something, as well as “say” something regarding whatever it is they are about. To distinguish veridical from false representations, there must be a way for these separate aspects to come apart; hence, we explain (ii) by providing independent theories of what I call f-reference and f-predication (the ‘f’ simply connotes ‘fundamental’, to distinguish these things from their natural language counterparts). -/- Causal theories of representation typically founder on error, or on what Fodor has called the disjunction problem. Resemblance or isomorphism theories typically founder on what I’ve called the non-uniqueness problem, which is that isomorphisms and resemblance are practically unconstrained and so representational content cannot be uniquely determined. These traditional problems provide the motivation for my theory, the structural preservation theory, as follows. F-reference, like reference, is a specific, asymmetric relation, as is causation. F-predication, like predication, is a non-specific relation, as predicates typically apply to many things, just as many relational systems can be isomorphic to any given relational system. Putting these observations together, a promising strategy is to explain f-reference via causal history and f-predication via something like isomorphism between relational systems. -/- This dissertation should be conceptualized as having three parts. After motivating and characterizing the problem in chapter 1, the first part is the negative project, where I review and critique Dretske’s, Fodor’s, and Millikan’s theories in chapters 2-4. Second, I construct my theory about the nature of representation in chapter 5 and defend it from objections in chapter 6. In chapters 7-8, which constitute the third and final part, I address the question of how representation is implemented in biological systems. In chapter 7 I argue that single-cell intracortical recordings taken from awake Macaque monkeys performing a cognitive task provide empirical evidence for structural preservation theory, and in chapter 8 I use the empirical results to illustrate, clarify, and refine the theory.

In his recent book, Concepts: Where Cognitive Science Went Wrong, Jerry Fodor retracts the radical concept-nativism he once defended. Yet that postion stood, virtually unchallenged, for more than twenty years. This neglect is puzzling, as Fodor's arguments against concepts being learnable from experience remain unanswered, and nativism has historically been taken very seriously as a response to empiricism's perceived shortcomings. In this paper, I urge that Fodorean nativism should indeed be rejected. I argue, however, that its deficiencies are not so (...) obvious that they can simply be taken for granted. Fodor can counter extant objections by stressing two distinctions: between historicist and counterfactual semantic theories and between explaining reference and explaining concept-acquisition. But, I argue, this victory is pyrrhic. Reformulated as objections to his account qua theory of concept-acquisition, and not qua theory of reference, analogous difficulties are fatal to the Fodorean position. (shrink)

Commonsense psychology and cognitive science both regularly assume the existence of representational states. I propose a naturalistic theory of representation sufficient to meet the pretheoretical constraints of a "folk theory of representation", constraints including the capacities for accuracy and inaccuracy, selectivity of proper objects of representation, perspective, articulation, and "efficacy" or content-determined functionality. The proposed model states that a representing device is a device which changes state when information is received over multiple information channels originating at a single source. The (...) changed state of a representing device is a representation. The unitary information source which would give rise to the information impinging on the representing device, and hence, give rise to the representation, is the content of the representation. The model meets the pretheoretic constraints, and also conforms to available neurobiological data for two invertebrate species. (shrink)

The object of this paper is to discuss several issues raised by Fred Dretske’s account of the causal efficacy of content, as given in his book Explaining Behavior. To warrant the causal efficacy of folk-psychological properties while keeping attached to a naturalistic framework, Fred Dretske proposes that these properties are causes of a peculiar type, what he calls structuring causes. Structuring causes are not postulated ad hoc, to somehow account for the causal efficacy of content. Dretske claims that we independently (...) need this dualism of causes to make sense of some of our (not necessarily involving mental states) causal explanations. Even if this variety of dualism is not untenable from a openly-minded physicalistic viewpoint, it seems for several reasons preferable to establish that content properties are causally efficacious in the same sense that physical properties are. The main point I will try to make in this paper is a metaphysical one, namely, that Drestke’s structuring causes are causes of a more ordinary kind. I will try to show that we can make sense of the phenomena that structuring causes are introduced to account for in more conservative terms, having only recourse to the material we must anyway posit to understand ordinary causal explanations.

This article is the sequel to 'Intentionality and Modern philosophical psychology, I. The modern reduction of intentionality,' (Philosophical Psychology, 3 (2), 1990) which examined the view of intentionality pioneered by Carnap and reaching its apotheosis in the work of Daniel Dennett. In 'Intentionality and modem philosophical psychology, II. The return to representation' (Philosophical Psychology, 4(1), 1991) I examined the approach to intentionality which can be traced back to the work of Noam Chomsky but which has been given its canonical treatment (...) in the work of Jerry Fodor. In this article, the last in the series, I explore a very recent approach to intentionality which has been associated especially with the work of Ruth Garrett Millikan and Colin McGinn, and might, if the phrase were not so rebarbative, be called “the biologizing of intentionality'.

This paper attempts to do two things. First, it recounts the problem of intentionality, as it has typically been conceptualized, and argues that it needs to be reconceptualized in light of the radical form of externalism most commonly referred to as the extended mind thesis. Second, it provides an explicit, novel argument for that thesis, what I call the argument from meaning making, and offers some defense of that argument. This second task occupies the core of the paper, and in (...) completing it I distinguish _active _ _cognition_ from _cyborg fantasy arguments_ for externalism, and develop the analogy between the extended mind thesis in the cognitive sciences and developmental systems theory in developmental biology. The rethinking of the problem of intentionality on offer leads not so much to a solution as to a dissolution of that problem, as traditionally conceived. (shrink)

The origin of memories is thought to be found in sensory perception. This conception is central to how the memory sciences characterize encoding. This paper considers how novel memory traces can be formed independently of external sensory inputs. I present a case study in which memory traces are created without sensory perception using a technique I call optogenetic memory implantation. Comparing this artificial process with normal memory encoding, I consider its implications for rethinking the causal chain that leads to remembering.

El objetivo de este trabajo es presentar una objeción a uno de los principios centrales de la Teoría Representacional de la Mente (TRM): la idea de que la noción de representación interna tiene una función primordial en la explicación de la actividad cognitiva. De acuerdo con la TRM, la vida cognitiva de un organismo consiste esencialmente en la formación, procesamiento y almacenamiento de representaciones internas. Tales representaciones son vistas como objetos o eventos concretos capaces de influir causalmente en los procesos (...) cognitivos de los organismos. Expuesta en forma de dilema, la objeción pretende mostrar las dificultades inherentes a la postulación de representaciones internas, dada la manera en que estas representaciones y su operación han sido concebidas en el marco mismo de la TRM. La cuestión que introduce al dilema es: ¿en virtud de qué propiedades una representación interna influye en la actividad cognitiva de un organismo? Dos respuestas son posibles: en virtud de sus propiedades representacionales o en virtud de sus propiedades no representacionales. En la sección 1 se mostrarán las consecuencias problemáticas de cada una de estas respuestas y en la sección 2 se discutirán dos ejemplos que ilustran estas dificultades. El resultado del dilema es que la noción de representación interna es incapaz de satisfacer la función explicativa que le ha sido asignada por la propia TRM. (shrink)

Imagine a zombie world that looks “from the outside” just like ours, but where there is no phenomenal consciousness. Creatures that look like us move about just as we do and make the same noises we do, but nobody experiences or feels anything. How much of the epistemic value that’s exemplified in our world survives in that one? The short answer is: any kind of epistemic value that requires the occurrence of consciousness for its exemplification cannot exist in that world, (...) but epistemic value that doesn’t require consciousness can exist. The real question, though, is what kinds of epistemic value require the occurrence of consciousness. We will consider four central epistemic values: justification, truth, acquaintance, and understanding. (shrink)

This paper looks at the nature of normal-proper functions and the role they play in theories of representational content. More specifically: I lay down two desiderata for a theory which tries to capture what's distinctive of normal-proper functions and discuss two prominent theories which claim to satisfy them. I discuss the advantages of having normal-proper functions ground a theory of representational content. And, I look at both orthodox and heterodox versions of such theories.

Non-naturalism is the view that normative properties are response-independent, irreducible to natural properties, and causally inefficacious. An underexplored question for non-naturalism concerns the metasemantics of normative terms. Ideally, the non-naturalist could remain ecumenical, but it appears they cannot. Call this challenge the metasemantic challenge. This chapter suggests that non-naturalists endorse an epistemic account of reference determination of the sort recently defended by Imogen Dickie, with some modifications. An important implication of this account is that, if correct, a fully fleshed out (...) moral epistemology will simultaneously rebut metasemantic objections to non-naturalism. Thus, both the metasemantic and the more widely discussed epistemological challenges in effect amount to one. Before setting out the positive view, the chapter considers why all of the traditional metasemantic theories cause trouble for the non-naturalist. This includes discussions of teleosemantics, conceptual role semantics, as well as Schroeter and Schroeter’s “connectedness” model. (shrink)

Structural representations are increasingly popular in philosophy of cognitive science. A key virtue they seemingly boast is that of meeting Ramsey's job description challenge. For this reason, structural representations appear tailored to play a clear representational role within cognitive architectures. Here, however, I claim that structural representations do not meet the job description challenge. This is because even our most demanding account of their functional profile is satisfied by at least some receptors, which paradigmatically fail the job description challenge. Hence, (...) the functional profile typically associated with structural representations does not identify representational posits. After a brief introduction, I present, in the second section of the paper, the job description challenge. I clarify why receptors fail to meet it and highlight why, as a result, they should not be considered representations. In the third section I introduce what I take to be the most demanding account of structural representations at our disposal, namely Gładziejewski's account. Provided the necessary background, I turn from exposition to criticism. In the first half of the fourth section, I equate the functional profile of structural representations and receptors. To do so, I show that some receptors boast, as a matter of fact, all the functional features associated with structural representations. Since receptors function merely as causal mediators, I conclude structural representations are mere causal mediators too. In the second half of the fourth section I make this conclusion intuitive with a toy example. I then conclude the paper, anticipating some objections my argument invites. (shrink)

How language works — its functions, mechanisms, and limitations — matters to the early moderns as much as it does to contemporary philosophers. Many of the moderns make reflection on language central to their philosophical projects, both as a tool for explaining human cognition and as a weapon to be used against competing views. Even in philosophers for whom language is less central, we can find important connections between their views on language and their other philosophical commitments.

The Shape of Agency offers interlinked explanations of the basic building blocks of agency, as well as its exemplary instances. The first part offers accounts of a collection of related phenomena that have long troubled philosophers of action: control over behaviour, non-deviant causation, and intentional action. These accounts build on earlier work in the causalist tradition, and undermine the claims made by many that causalism cannot offer a satisfying account of non-deviant causation, and therefore fails as an account of intentional (...) action. The second part turns to modes of agentive excellence—ways that agents display quality of form—providing a novel account of skill, including an account of the ways that agents display more or less skill. Shepherd discusses the role of knowledge in skill, and concludes that while knowledge is often important, it is inessential. This leads to a discussion of the way that knowledge of action and knowledge of how to act informs action execution. Knowledgeable action includes a unique epistemic underpinning: in knowledgeable action, the agent has authoritative knowledge of what she is doing and how she is doing it when and because she is poised to control her action by way of practical reasoning.

Is there some general reason to expect organisms that have beliefs to have false beliefs? And after you observe that an organism occasionally occupies a given neural state that you think encodes a perceptual belief, how do you evaluate hypotheses about the semantic content that that state has, where some of those hypotheses attribute beliefs that are sometimes false while others attribute beliefs that are always true? To address the first of these questions, we discuss evolution by natural selection and (...) show how organisms that are risk-prone in the beliefs they form can be fitter than organisms that are risk-free. To address the second question, we discuss a problem that is widely recognized in statistics – the problem of over-fitting – and one influential device for addressing that problem, the Akaike Information Criterion (AIC). We then use AIC to solve epistemological versions of the disjunction and distality problems, which are two key problems concerning what it is for a belief state to have one semantic content rather than another.

This thesis offers a teleosemantic account of moral discourse and judgment. It develops a number of views about the function and content of moral judgments and the nature of moral discourse based on Ruth Millikan’s theory of intentional content and the functions of intentional attitudes. Non-cognitivists in meta-ethics have argued that moral judgments are more akin to desires and other motivational attitudes than to descriptive beliefs. I argue that teleosemantics allows us to assign descriptive content to motivational attitudes and hence (...) that even if the non-cognitivist is correct, moral judgments can be said to describe the world. Moreover, given further teleosemantic assumptions, this conclusion has consequences that are both surprising and interesting. First of all, while moral judgments have descriptive content, moral statements do not. The purpose of moral discourse is not to convey beliefs that are true simpliciter, but to convey attitudes that are descriptively correct when tokened by the addressee. Consequently, moral discourse requires speakers to adapt to hearers in order to secure their assent and bring them into "community of judgment" with themselves. Secondly, the descriptive content of a motivational attitude is partly a matter of the subject’s own preferences and circumstances. In particular, the descriptive correctness of a moral judgment is partly a function of the degree to which it is shared with others. Since a moral judgment also motivates the subject to spread it, it has the ability to, in a certain sense, make itself true. If regular descriptive beliefs are supposed to adapt the subject to the world, a moral judgment also has the capacity to adapt the world to the subject. (shrink)

According to the sceptic Saul Kripke envisages in his celebrated book on Wittgenstein on rules and private language, there are no facts about an individual that determine what she means by any given expression. If there are no such facts, the question then is, what justifies the claim that she does use expressions meaningfully? Kripke’s answer, in a nutshell, is that she by and large uses her expressions in conformity with the linguistic standards of the community she belongs to. While (...) Kripke’s sceptical problem has gripped philosophers for over three decades, few, if any, have been satisfied by his proposed solution, and many have struggled to come up with one of their own. The purpose of this paper is to show that a more satisfactory answer to Kripke’s challenge can be developed on the basis of Donald Davidson’s writings on triangulation, the idea of two individuals interacting simultaneously with each other and the world they share. It follows from the triangulation argument that the facts that can be regarded as determining meaning are irreducible. Yet, contra Kripke, they are not mysterious, for the argument does spell out what is needed for an individual’s expressions to be meaningful. (shrink)

The sharpest corner of the cutting edge of recent epistemology is to be found in Richard Pettigrew’s Accuracy and the Laws of Credence. In this fine book Pettigrew argues that a certain kind of accuracy-based value monism entails that rational credence manifests a host of features emphasized by anti-externalists in epistemology. Specifically, he demonstrates how a particular version of accuracy-based value monism—to be discussed at length below—when placed with some not implausible views about how epistemic value and rationality relate to (...) one another, ensures that rational credence manifests many of the structural properties emphasized by those who give evidence pride of place in the theory of rationality. A major goal of Pettigrew’s book, then, is to make clear how accuracy-based value monism fits together with the phenomena used by those who argue against accuracy-based externalism.2 2. (shrink)

In this paper, I argue that computationalism is a progressive research tradition. Its metaphysical assumptions are that nervous systems are computational, and that information processing is necessary for cognition to occur. First, the primary reasons why information processing should explain cognition are reviewed. Then I argue that early formulations of these reasons are outdated. However, by relying on the mechanistic account of physical computation, they can be recast in a compelling way. Next, I contrast two computational models of working memory (...) to show how modeling has progressed over the years. The methodological assumptions of new modeling work are best understood in the mechanistic framework, which is evidenced by the way in which models are empirically validated. Moreover, the methodological and theoretical progress in computational neuroscience vindicates the new mechanistic approach to explanation, which, at the same time, justifies the best practices of computational modeling. Overall, computational modeling is deservedly successful in cognitive science. Its successes are related to deep conceptual connections between cognition and computation. Computationalism is not only here to stay, it becomes stronger every year. (shrink)

Esta enciclopédia abrange, de uma forma introdutória mas desejavelmente rigorosa, uma diversidade de conceitos, temas, problemas, argumentos e teorias localizados numa área relativamente recente de estudos, os quais tem sido habitual qualificar como «estudos lógico-filosóficos». De uma forma apropriadamente genérica, e apesar de o território teórico abrangido ser extenso e de contornos por vezes difusos, podemos dizer que na área se investiga um conjunto de questões fundamentais acerca da natureza da linguagem, da mente, da cognição e do raciocínio humanos, bem (...) como questões acerca das conexões destes com a realidade não mental e extralinguística. A razão daquela qualificação é a seguinte: por um lado, a investigação em questão é qualificada como filosófica em virtude do elevado grau de generalidade e abstracção das questões examinadas (entre outras coisas); por outro, a investigação é qualificada como lógica em virtude de ser uma investigação logicamente disciplinada, no sentido de nela se fazer um uso intenso de conceitos, técnicas e métodos provenientes da disciplina de lógica. O agregado de tópicos que constitui a área de estudos lógico-filosóficos é já visível, pelo menos em parte, no Tractatus Logico-Philosophicus de Ludwig Wittgenstein, uma obra publicada em 1921. E uma boa maneira de ter uma ideia sinóptica do território disciplinar abrangido por esta enciclopédia, ou pelo menos de uma porção substancial dele, é extrair do Tractatus uma lista dos tópicos mais salientes aí discutidos; a lista incluirá certamente tópicos do seguinte género, muitos dos quais se podem encontrar ao longo desta enciclopédia: factos e estados de coisas; objectos; representação; crenças e estados mentais; pensamentos; a proposição; nomes próprios; valores de verdade e bivalência; quantificação; funções de verdade; verdade lógica; identidade; tautologia; o raciocínio matemático; a natureza da inferência; o cepticismo e o solipsismo; a indução; as constantes lógicas; a negação; a forma lógica; as leis da ciência; o número.

It is well known that informational theories of representation have trouble accounting for error. Informational semantics is a family of theories attempting a naturalistic, unashamedly reductive explanation of the semantic and intentional properties of thought and language. Most simply, the informational approach explains truth-conditional content in terms of causal, nomic, or simply regular correlation between a representation and a state of affairs. The central work is Dretske (1981), and the theory was largely developed at the University of Wisconsin by Fred (...) Dretske, Dennis Stampe, and Berent Enc. Recently, informational semantics has roamed far beyond its Wisconsin home, and built a sizeable collection of followers. Converts include Jerry Fodor (1987), Robert Stalnaker (1984) and, less faithfully, Paul and Patricia Churchland (1983) and Hartry Field (1986). But for some years informational semantics has been hounded by a problem with error – the classic presentation is Fodor (1984) – and no other problem has hounded the theory so persistently. (shrink)

In The Elm and the Expert (1994), Fodor rejects the notion of narrow content as superfluous. He envisions a scientific intentional psychology that adverts only to broad content properties in its explanations. I show that there has been no change in Fodor's treatment of Frege cases and cases involving the so‐called deferential concepts. And for good reason: his notion of narrow content (1985‐91) couldn't explain them. The only apparent change concerns his treatment of Twin Earth cases. However, I argue that (...) the notion of broad content that his purely informational semantics delivers is, in some interesting sense, equivalent to the mapping notion of narrow content he officially gave up. I also critically reconstruct the evolution of Fodor's thinking between 1980 and 1994. (shrink)

Daniel D. Hutto and Glenda Satne expose, and suggest a way to resolve, what they see as an “essential tension” which has plagued what they take to be the most promising approach to the nature of contentful states, that is, the neo-pragmatist approach. According to this approach, an adequate account of content essentially appeals to the notion of a social practice. This paper is a critical assessment of their proposal. On their view, the tension stems from the fact that participation (...) in a social practice seems to require that, in order to participate in one, an individual must have contentful states. This entails that participation in social practices cannot explain the origin of contentful states. They argue that the tension dissipates once contentless forms of intentionality come into view. I show that the tension cannot be addressed in the way in which they suggest, for the intermediate steps between primitive intentionality and contentful intentionality cannot in fact fully be accounted for. Nevertheless, Hutto and Satne shed valuable light on the location and scope of the gap in the transition between mindlessness and contentful mindedness. (shrink)

ABSTRACT: I distinguish two sorts of motivation for dualism. One motivation is driven by the distinctive character of conscious phenomenology. The other is driven by the special character of normativity: Is rationality an even problem than consciousness? There is no dramatic climax in which I show that these two dualist currents have a common source; in fact, I think they are relatively independent.

This paper examines the relationship between a family of concepts involving reliable correlation, and a family of concepts involving adaptation and biological function, as these concepts are used in the naturalistic semantic theory of Dretske's "Explaining Behavior." I argue that Dretske's attempt to marry correlation and function to produce representation fails, though aspects of his failure point the way forward to a better theory.

Philosophers of mind and language who advance causal theories face a sort of conjunction problem. When we say that the thing had in mind or the thing referred to is a matter of what causally impacted the thinker or speaker, we must somehow narrow down the long conjunction of items in a causal chain, all of which contributed to the having in mind, but only one of which becomes the object of thought or the linguistic referent. Here, I sketch a (...) notion of cognitive focus intended to do this narrowing. The notion borrows three key aspects from visual focus and some technological aides—causation, amplification, and suppression. I suggest a broader application of this framework to address the conjunction problem not only in ordinary contexts of perceptual focus but also in evidence cases involving non-perceptual cognitive focus. I further suggest cognitive focus is helpful in distinguishing referential vs. attributive thought. (shrink)

An influential view in cognitive science is that computation in cognitive systems is semantic, conceptually depending on representation: to compute is to manipulate representations. I argue that accepting the non-semantic teleomechanistic view of computation lays the ground for a promising alternative strategy, in which computation helps to explain and naturalise representation, rather than the other way around. I show that this computation-based approach to representation presents six decisive advantages over the semantic view. I claim that it can improve the two (...) most influential current theories of representation, teleosemantics and structural representation, by providing them with precious tools to tackle some of their main shortcomings. In addition, the computation-based approach opens up interesting new theoretical paths for the project of naturalising representation, in which teleology plays a role in individuating computations, but not representations.

The disjunction problem and the distality problem each presents a challenge that any theory of mental content must address. Here we consider their bearing on purely probabilistic causal theories. In addition to considering these problems separately, we consider a third challenge—that a theory must solve both. We call this “the hard problem.” We consider 8 basic ppc theories along with 240 hybrids of them, and show that some can handle the disjunction problem and some can handle the distality problem, but (...) none can handle the hard problem. This is our main result. We then discuss three possible responses to that result, and argue that though the first two fail, the third has some promise. (shrink)

The Darwinian theory of evolution is itself evolving and this book presents the details of the core of modern Darwinism and its latest developmental directions. The authors present current scientific work addressing theoretical problems and challenges in four sections, beginning with the concepts of evolution theory, its processes of variation, heredity, selection, adaptation and function, and its patterns of character, species, descent and life. The second part of this book scrutinizes Darwinism in the philosophy of science and its usefulness in (...) understanding ecosystems, whilst the third section deals with its application in disciplines beyond the biological sciences, including evolutionary psychology and evolutionary economics, Darwinian morality and phylolinguistics. The final section addresses anti-Darwinism, the creationist view and issues around teaching evolution in secondary schools. The reader learns how current experimental biology is opening important perspectives on the sources of variation, and thus of the very power of natural selection. This work examines numerous examples of the extension of the principle of natural selection and provides the opportunity to critically reflect on a rich theory, on the methodological rigour that presides in its extensions and exportations, and on the necessity to measure its advantages and also its limits. Scholars interested in modern Darwinism and scientific research, its concepts, research programs and controversies will find this book an excellent read, and those considering how Darwinism might evolve, how it can apply to the human sciences and other disciplines beyond its origins will find it particularly valuable. Originally produced in French (Les Mondes Darwiniens), the scope and usefulness of the book have led to the production of this English text, to reach a wider audience. This book is a milestone in the impressive penetration by Francophone scholars into the world of Darwinian science, its historiography and philosophy over the last two decades. Alex Rosenberg, R.

This thesis proposes a perspective on language and its development by starting from two approaches. The first is the ecological-enactive approach to cognition. In opposition to the widespread idea that cognition is information-processing in the brain, the ecological-enactive approach explains human cognition in relational terms, as skilful interactions with a sociomaterial environment shaped by practices. The second is the metalinguistic approach to language, which holds that reflexive or metalinguistic language use – talking about talking – is crucial for understanding language (...) and its development. In particular, I defend two theses: 1. A child’s initial communicative behaviour can be explained in terms of attentional actions: social actions that function by directing someone else’s attention. 2. In order for the child’s communicative behaviour to be sensitive to key properties of language, such as semantic content and normativity, she needs to learn metalinguistic skills. The development of this ecological-enactive perspective on language serves two functions. First, the ecological-enactive approach started by considering basic behaviour, such as locomotion and grasping. An approach in the cognitive sciences, however, should be able to account for the full gamut of human cognition. If the perspective developed in this thesis is viable, this is a contribution to extending the ecological-enactive approach to typically human forms of cognition. Second, this perspective throws new light on philosophical problems concerning language. In the different chapters, I deal with questions concerning the nature of linguistic knowledge, explanations of communicative behaviour, and the origins of semantic content and linguistic normativity.

In this essay, we draw on John Haugeland’s work in order to argue that Burge is wrong to think that exercises of perceptual constancy mechanisms suffice for perceptual representation. Although Haugeland did not live to read or respond to Burge’s Origins of Objectivity, we think that his work contains resources that can be developed into a critique of the very foundation of Burge’s approach. Specifically, we identify two related problems for Burge. First, if (what Burge calls) mere sensory responses are (...) not representational, then neither are exercises of constancy mechanisms, since the differences between them do not suffice to imply that one is representational and the other is not. Second, taken by themselves, exercises of constancy mechanisms are only derivatively representational, so merely understanding how they work is not sufficient for understanding what is required for something, in itself, to be representational (and thereby provide a full solution to the problem of perceptual representation).
