The aim of this paper is to defend the structural concept of representation, as defined by homomorphisms, against its main objections, namely: logical objections, the objection from misrepresentation, theobjection from failing necessity, and the copy theory objection. The logical objections can be met by reserving the relation.

Internal relations are those relations that are intrinsic to the nature of one or more of the relata. They are a kind of essential relation, rather than an essential property. For example, an arc of a circle is internally related to the center of that circle in the sense that.

assumptions about the phenomena of interest with process models. Thus, phlogiston has been replaced by combustion, caloric by random thermal motion, and vital fluid by far- from-equilibrium self-reproducing organizations of process. The most significant exceptions to this historical pattern are found in studies of the mind. Here, substance assumptions are still ubiquitous, ranging from models of representation to those of emotions to personality and psychopathology. Substance assumptions do pernicious damage to our ability to understand such phenomena. In this discussion, I (...) will focus on the problem of representation. (shrink)

Function emerges in certain kinds of far-from-equilibrium systems. One important kind of function is that of interactive anticipation, an adaptedness to temporal complexity. Interactive anticipation is the locus of the emergence of normative representational content, and, thus, of representation in general: interactive anticipation is the naturalistic core of the evolution of cognition. Higher forms of such anticipation are involved in the subsequent macro-evolutionary sequence of learning, emotions, and reflexive consciousness.

Information and representation are thought to be intimately related. Representation, in fact, is commonly considered to be a special kind of information. It must be a _special_ kind, because otherwise all of the myriad instances of informational relationships in the universe would be representational -- some restrictions must be placed on informational relationships in order to refine the vast set into those that are truly representational. I will argue that information in this general sense is important to genuine agents, but (...) that it is a blind alley with regard to the attempt to understand representation. On the other hand, I will also argue that a different, quite non-standard, form of information is central to genuine representation. First I turn to some of the reasons why information as usually considered is the wrong category for understanding representation; second to an alternative model of representation -- one that is naturally emergent in autonomous agents, and that does involve information, but not in any standard form; and third I return to standard notions of informational relationships and show what they are in fact useful for. (shrink)

The dominant assumptions -- throughout contemporary philosophy, psychology, cognitive science, and artificial intelligence -- about the ontology underlying intentionality, and its core of representationality, is that of encodings -- some sort of informational or correspondence or covariation relationship between the represented and its representation that constitutes that representational relationship. There are many disagreements concerning details and implementations, and even some suggestions about claimed alternative ontologies, such as connectionism (though none that escape what I argue is the fundamental flaw in these (...) dominant approaches). One assumption that seems to be held by all, however, usually without explication or defense, is that there is _one_ singular underlying ontology to representationality. In this paper, I argue that there are in fact quite a number of ontologies that manifest representationality -- levels of representationality -- and that _none_ of them are the standard "manipulations of encoded symbols" ontology, nor any other variation on the informational approach to representation. Collectively, these multiple representational ontologies constitute a framework for cognition, whether natural or artificial. (shrink)

This article focuses on the problem of representational content. Accounting for representational content is the central issue in contemporary naturalism: it is the major remaining task facing a naturalistic conception of the world. Representational content is also the central barrier to contemporary cognitive science and artificial intelligence: it is not possible to understand representation in animals nor to construct machines with genuine representation given current (lack of) understanding of what representation is. An elaborated critique is offered to current approaches to (...) representation, arguing that the basic underlying approach is, at root, logically incoherent, and, thus, that standard approaches are doomed to failure. An alternative model of representation - interactivism - is presented that avoids or solves the problems facing standard approaches. Interactivism is framed by a version of functionalism, and a naturalization of that functionalism completes an outline of a naturalization of representation and representational content. (shrink)

Representationalism in cognitive science holds that semantic meaning should be explained by representations in the mind or brain. In this paper it is argued that semantic meaning should instead be explained by an abstract theory of semantic machines -- machines with predicative capability. The concept of a semantic machine (like that of a Turing machine or of Dennett's intentional systems ) is not a physical concept -- although it has physical implementations. The predicative competence of semantic machines is defined in (...) terms of independent agreement alone (cf. independent, and yet synchronised, clocks). Abstract theories are analysed as systems of quasi-apriori rules for abstract predicates. A relatively limited number of such theories and a few fundamental dimensions (space, time, mass, etc.) are today assumed to exhaust physical reality. However, that assumption need not be in conflict with predicates that cannot be defined in physical terms – for instance the functional and intentional terms that are crucial for cognitive science.

Several conditions for being an intrinsically intentional agent are put forward. On a first level of intentionality the agent has representations. Two kinds are described: cued and detached. An agent with both kinds is able to represent both what is prompted by the context and what is absent from it. An intermediate level of intentionality is achieved by having an inner world, that is, a coherent system of detached representations that model the world. The inner world is used, e.g., for (...) conditional and counterfactual thinking. Contextual or indexical representations are necessary in order that the inner world relates to the actual external world and thus can be used as a basis for action. To have full-blown intentionality, the agent should also have a detached self-awareness, that is, be able to entertain self-representations that are independent of the context. (shrink)

Descriptive metaphysics investigates our naïve ontology as this is articulated in the content of our perception or of our pre-reflective thought about the world. But is access to such content reliable? Sceptics about the standard modes of access (introspection, or language-driven intuitions) may think that investigations in descriptive metaphysics can be aided by the controlled findings of cognitive science. Cognitive scientists have studied a promising range of representational advantages, that is, ways in which cognition favours one type of entity over (...) another. The notion of representational advantage is investigated and some scepticism is expressed as to its appropriateness for use in descriptive metaphysics. (shrink)

In Philosophy of Mental Representation five of the most original and important thinkers in philosophy of mind engage in an overlapping dialogue about mental representation. In new papers, contributors Andy Clark, Robert Cummins, Daniel Dennett, John Haugeland, and Brian Cantwell Smith each investigate the views and claims of one of the other contributors regarding mental representation. The subject then offers a reply. An exciting feature of this collection is the dynamic discussion among all contributors following each exchange. This collection offers (...) the latest thinking on mental representation carefully and critically analyzed by the leading thinkers in the field. (shrink)

The selected texts for this discussion were two recent pieces by Dennett (.

This paper is about two kinds of mental content and how they are related. We are going to call them representation and indication. We will begin with a rough characterization of each. The differences, and why they matter, will, hopefully, become clearer as the paper proceeds.

Perhaps we can all agree that in order for intelligent activity to be produced by embodied nervous systems, those nervous systems have to have things in them that are about other things in the following minimal sense: there is information about these other things not just present but usable by the nervous system in its modulation of behavior. (There is information about the climatic history of a tree in its growth rings--the information is present, but not usable by the tree.) (...) The disagreements set in when we start trying to characterize what these things-aboutthings are--are they "just" competences or dispositions embodied somehow (e.g., in connectionist networks) in the brain, or are they more properly mental representations, such as sentences in a language of thought, images, icons, maps, or other data structures? And if they are "symbols", how are they "grounded"? What, more specifically, is the analysis of the aboutness that these things must have? Is it genuine intentionality or mere as if intentionality? These oft-debated questions are, I think, the wrong questions to be concentrating on at this time, even if, "in the end", they make sense and deserve answers. These questions have thrived in the distorting context provided by two ubiquitous idealizing assumptions that we should try setting aside: an assumption about how to capture content and an assumption about how to isolate the vehicles of content from the "outside" world.

In a previous Philo article, it was shown how properties could be ontologically dispensed with via a representational analysis: to be an X is to comprehensively represent all the properties of an X. The current paper extends that representationalist (RT) theory by explaining representation itself in parallel epistemic rather than ontological terms. On this extended RT (ERT) theory, representations of X, as well as the real X, both may be identified as providing information about X, whether partial or comprehensive. But (...) that information does not match ontological, property-based analyses of X, so it is epistemically fundamental–hence supporting a broadly conceptualist rather than nominalist metaphysics.

Intelligent systems are faced with the problem of securing a principled (ideally, veridical) relationship between the world and its internal representation. I propose a unified approach to visual representation, addressing both the needs of superordinate and basic-level categorization and of identification of specific instances of familiar categories. According to the proposed theory, a shape is represented by its similarity to a number of reference shapes, measured in a high-dimensional space of elementary features. This amounts to embedding the stimulus in a (...) low-dimensional proximal shape space. That space turns out to support representation of distal shape similarities which is veridical in the sense of Shepard's (1968) notion of second-order isomorphism (i.e., correspondence between distal and proximal similarities among shapes, rather than between distal shapes and their proximal representations). Furthermore, a general expression for similarity between two stimuli, based on comparisons to reference shapes, can be used to derive models of perceived similarity ranging from continuous, symmetric, and hierarchical, as in the multidimensional scaling models (Shepard, 1980), to discrete and non-hierarchical, as in the general contrast models (Tversky, 1977; Shepard and Arabie, 1979).

James Elkins has shaped the discussion about how we—as artists, as art historians, or as outsiders—view art. He has not only revolutionized our thinking about the purpose of teaching art, but has also blazed trails in creating a means of communication between scientists, artists, and humanities scholars. In Six Stories from the End of Representation , Elkins weaves stories about recent images from painting, photography, physics, astrophysics, and microscopy. These images, regardless of origin, all fail as representations: they are blurry, (...) dark, pixellated, or otherwise unclear. In these opaque images, Elkins finds an opportunity to create stories that speak simultaneously to artists and to scientists, and to open both those fields to those of us who have little purchase in either. Regarding each image through the lens of the discipline that produced it, Elkins simultaneously affirms the unique structure of each way of viewing the world and brings those views together into a vibrant conversation.

Dreyfus enlists the aid of Merleau-Ponty in his critique of representationalist theories of cognition. Such theories posit a representational element at some level of cognitive activity. The nature of the representation and how we think of it will depend upon the level at which one claims to find it. If we consider the case of perception, at one extreme it might be claimed that the representation is a conscious one, that is, that the perceiving subject is conscious of a representation, (...) a _Vorstellung_ in the Kantian sense. In this case, it would clearly come between the perceiving subject and the world and in that sense interfere with a direct perception of the world. This sort of representational theory would be equivalent to idealism, and for good phenomenological reasons it is rejected by Merleau-Ponty and Dreyfus. At the other extreme, it is possible to find cognitive scientists talking about representations at the level of brain activity. Neural representations, either firing patterns or the actual "hard wiring" of neuronal connections (as, for example, neural maps in the somatosensory and motor areas responsible for the experience of the subject's own body), in some way enable perception. At this level of description there are various debates about how these mechanisms can be called representational. If the concept of representation involves reference to the perceptual field, in what sense does a neuronal pattern refer? There are also the familiar debates about how such mechanisms actually function, as well as the difficult problem of how such functions actually translate into personal level experience. Before these debates get off the ground, however, Dreyfus wants to steal the ammunition. He denies that there are representations at the level of brain processes. (shrink)

?Representation? is a concept which occurs both in cognitive science and philosophy. It has common features in both settings in that it concerns the explanation of behaviour in terms of the way the subject categorizes and systematizes responses to its environment. The prevailing model sees representations as causally structured entities correlated on the one hand with elements in a natural language and on the other with clearly identifiable items in the world. This leads to an analysis of representation and cognition (...) in terms of formal symbols and their relations. But human perception and cognition use multiple informational constraints and deal with unsystematic and messy input in a way best explained by Parallel Distributed Processing models. This undermines the claim that a formal representational theory of mind is ?the only game in town?. In particular it suggests a radically different model of brain function and its relation to epistemology from that found in current representational theories. (shrink)

The emulation theory of representation is developed and explored as a framework that can revealingly synthesize a wide variety of representational functions of the brain. The framework is based on constructs from control theory (forward models) and signal processing (Kalman filters). The idea is that in addition to simply engaging with the body and environment, the brain constructs neural circuits that act as models of the body and environment. During overt sensorimotor engagement, these models are driven by efference copies in (...) parallel with the body and environment, in order to provide expectations of the sensory feedback, and to enhance and process sensory information. These models can also be run off-line in order to produce imagery, estimate outcomes of different actions, and evaluate and develop motor plans. The framework is initially developed within the context of motor control, where it has been shown that inner models running in parallel with the body can reduce the effects of feedback delay problems. The same mechanisms can account for motor imagery as the off-line driving of the emulator via efference copies. The framework is extended to account for visual imagery as the off-line driving of an emulator of the motor-visual loop. I also show how such systems can provide for amodal spatial imagery. Perception, including visual perception, results from such models being used to form expectations of, and to interpret, sensory input. I close by briefly outlining other cognitive functions that might also be synthesized within this framework, including reasoning, theory of mind phenomena, and language. Key Words: efference copies; emulation theory of representation; forward models; Kalman filters; motor control; motor imagery; perception; visual imagery. (shrink)

b>: In this article I outline, apply, and defend a theory of natural representation. The main consequences of this theory are: i) representational status is a matter of how physical entities are used, and specifically is not a matter of causation, nomic relations with the intentional object, or information; ii) there are genuine (brain-)internal representations; iii) such representations are really representations, and not just farcical pseudo-representations, such as attractors, principal components, state-space partitions, or what-have-you;and iv) the theory allows us to (...) sharply distinguish those complex behaviors which are genuinely cognitive from those which are merely complex and adaptive.

This authored book provides an innovative and systematic account of key debates within the social psychology of knowledge, using the theory of social representations as a guide. This account is then elaborated and integrated into a conceptually coherent theoretical framework to further the social psychological dimensions of the relationship between representations, knowledge and context. Jovchelovitch highlights the social psychological components of the process of knowledge formation and their impact in the constitution of communities, culture and public spheres. Whilst this exploration (...) contributes to an understanding of the genesis, logic and function of knowledge in social life, it also shows that context is essential to understanding the dynamics of representation and emphasises the fundamental unity between the two. This book offers a significant and stimulating contribution to the field of social representations and will make essential reading for those wanting to follow this debate at thecutting edge of social, cultural and developmental psychology as well as sociology, anthropology and cultural studies.

The current orthodoxy on mental representation can be characterized in terms of three
central ideas. The first is ontological, the second semantic, and the third methodological. After
elucidating those, I argue that the emerging picture of mental representation is satisfactory only as
an account of mental representation at the sub-personal level. It is unsatisfactory, in a principled
way, as an account of mental representation at the personal level.

Several accounts of representation in cognitive systems have recently been proposed. These look for a theory that will establish how a representation comes to have a certain content, and how these representations are used by cognitive systems. Covariation accounts are unsatisfactory, as they make intelligent reasoning and cognition impossible. Cummins' interpretation-based account cannot explain the distinction between cognitive and non-cognitive systems, nor how certain cognitive representations appear to have intrinsic meaning. Cognitive systems can be defined as model-constructers, or systems that (...) use information from interpreted models as arguments in the functions they execute. An account based on this definition solves many of the problems raised by the earlier proposals. (shrink)

In his, ‘Descartes' Ontology of Thought’, Alan Nelson presents, on Descartes' behalf, a compositional theory of mental representation according to which the content of any mental representation is either simple or is entirely constituted by a combination of innate simples. Here the simples are our ideas of God, thought, extension, and union. My objection will be that it is simply ludicrous to think that any four simples are adequate to the task of combining to constitute all of human thought, and (...) that the simples God, thought, extension, and union are particularly ill suited to it.

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)

In this reply we claim that, contra Dreyfus, the kinds of skillful performances Dreyfus discusses _are_ representational. We explain this proposal, and then defend it against an objection to the effect that the representational notion we invoke is a weak one countenancing only some global state of an organism as a representation. According to this objection, such a representation is not a robust, projectible property of an organism, and hence will gain no explana- tory leverage in cognitive scientific explanations. We (...) argue on conceptual and empirical grounds that the representations we have identified are not weak unprojectible global states of organisms, but instead genuinely explanatory representational parts of persons.

Representation is a central part of models in cognitive science, but recently this idea has come under attack. Researchers advocating perceptual symbol systems, situated action, embodied cognition, and dynamical systems have argued against central assumptions of the classical representational approach to mind.

We argue that representation should remain a core part of cognitive science, but that the insights from these alternative approaches must be incorporated (...) into models of cognitive processing.

Eighteenth-century France witnessed the rise of matter itself—in forms ranging from atoms to anatomies—as a privileged object of study. Voluptuous Philosophy redefines what is at stake in the emergence of an enlightened secular materialism by showing how questions of figure—how should a body be represented? What should the effects of this representation be on readers?—are tellingly and consistently located at the very heart of 18th-century debates about the nature of material substance. French materialisms of the Enlightenment are crucially invested not (...) only in the development of a sophisticated theoretical apparatus around the notion of matter but in the production of specific relationships between readers and the "matter" of the texts that they consume. How, the book asks, did the period's fascination with a markedly immaterial and ephemeral event—the reading of works of fiction—come to coincide with what appears to be a gradual materialization of human subjects: men and women who increasingly manage to envision themselves transfigured, as the century wears on, into machines, animals, and even, in the work of the Marquis de Sade, tables and chairs? In what way did the spread of new philosophies of matter depend upon the ability of readers to perceive certain figures of speech as literally and immediately true—to imagine themselves as fully material bodies even as they found themselves most deeply compelled by disembodied literary forms? More broadly, in what sense does the act of reading literature alter and transfigure our perceptions of what is, and can be, real? Voluptuous Philosophy articulates the gradual coming into being of literature as a distinct arena of textual production with the rise of an enlightened reader who remains abstracted from the bodily symptoms that any given piece of writing may induce in him. The very definition of "the literary" as an autonomous field, this book suggests, may, ironically, be dependent upon the simultaneous construction of a material world that remains fully immune to its effects.

In his response to my Why There Are No Mental Representations, Robert Cummins accused me of having misinterpreted his views, and attempted to undermine a crucial premise of my argument, which claimed that one could only define a semantic type non-semantically by stipulating which tokens should receive a uniform interpretation. I respond to the charge and defend the premise.

There are two very different ways of thinking about perception. According to the first one, perception is representational: it represents the world as being a certain way. According to the second, perception is a genuine relation between the perceiver and a token object. These two views are thought to be incompatible. My aim is to work out the least problematic version of the representational view of perception that preserves the most important considerations in favor of the relational view. According to (...) this version of representationalism, the properties represented in perception are tropes—abstract particulars that are logically incapable of being present in two distinct individuals at the same time. I call this view ‘trope representationalism’. (shrink)

The notion of a "mental representation" is, arguably, in the first instance a theoretical construct of cognitive science. As such, it is a basic concept of the Computational Theory of Mind, according to which cognitive states and processes are constituted by the occurrence, transformation and storage (in the mind/brain) of information-bearing structures (representations) of one kind or another.

Nearly all of the ways philosophers currently attempt to define the terms ‘representation’ and ‘function’ undermine the scientific application of those terms by rendering the scientific explanations in which they occur vacuous. Since this is unacceptable, we must develop analyses of these terms that avoid this vacuity. Robert Cummins argues in this fashion in Representations, Targets, and Attitudes. He accuses ‘use theories’ of representational content of generating vacuous explanations, claims that nearly all current theories of representational content are use theories, (...) and offers a non-use theory of representational content which avoids explanatory vacuity. One task I undertake in this article is to develop an alternative non-use theory which avoids an objection fatal to that theory. (shrink)

I critique an ancient argument for the possibility of non-linguistic deductive inference. The argument, attributed to Chrysippus, describes a dog whose behavior supposedly reflects disjunctive syllogistic reasoning. Drawing on contemporary robotics, I urge that we can equally well explain the dog's behavior by citing probabilistic reasoning over cognitive maps. I then critique various experimentally-based arguments from scientific psychology that echo Chrysippus's anecdotal presentation.

I argue that maps do not feature predication, as analyzed by Frege and Tarski. I take as my foil (Casati and Varzi, Parts and places, 1999), which attributes predication to maps. I argue that the details of Casati and Varzi’s own semantics militate against this attribution. Casati and Varzi emphasize what I call the Absence Intuition: if a marker representing some property (such as mountainous terrain) appears on a map, then absence of that marker from a map coordinate signifies absence (...) of the corresponding property from the corresponding location. Predication elicits nothing like the Absence Intuition. “F(a)” does not, in general, signify that objects other than a lack property F. On the basis of this asymmetry, I argue that attaching a marker to map coordinates is a different mode of semantic composition than attaching a predicate to a singular term. (shrink)

This volume argues in favor of rethinking basic issues in cognitive science in the context of recent developments.

The representation of objects and faces by neurons in the temporal lobe visual cortical areas of primates has the property that the neurons encode relatively independent information in their firing rates. This means that the number of stimuli that can be encoded increases exponentially with the number of neurons in an ensemble. Moreover, the information can be read by receiving neurons that perform just a synaptically weighted sum of the firing rates being received. Some ways in which these representations become (...) grounded in the world are described. The issue of syntactic binding in representations, and of its value for a higher order thought system, is discussed. (shrink)

b>. The current essay introduces the guidance theory of representation, according to which the content and intentionality of representations can be accounted for in terms of the way they provide guidance for action. We offer a brief account of the biological origins of representation, a formal characterization of the guidance theory, some examples of its use, and show how the guidance theory handles some traditional problem cases for representation: the problems of error and of representation of fictional and abstract entities.

This paper explores a new understanding of mind or mental representation by arguing that contents at the personal level are not carried by vehicles. Contentful mental states at the personal level are distinctive by virtue of their vehicle-less nature: the subpersonal physiological or functional states that are associated with and enable personal level contents cannot be understood as their vehicles, neither can the sensations or the sensory conditions associated with perceptual contents. This result is obtained by first extending the interpretationist (...) ideas of Davidson and Dennett to show that subpersonal physiological or functional states cannot be construed as the vehicles of personal level contents. Then the anti-foundationalist arguments of Sellars are extended to show that sensory states cannot stand as vehicles to perceptual contents. The line of argumentation extended from Sellars also provides a critique of the current trend to posit non-conceptual contents. (shrink)

Abstract A survey of different senses of the term ?representation? is presented. The presentation is guided by the appraisal that this key term is employed in the cognitive literature in different senses and that the distinction between these is not always explicitly stated or appreciated. Furthermore, the different senses seem to be associated with different rationales for the postulation of representation. Given that there may be a lack of convergence between the various senses of the construct in question and the (...) rationales for its postulation, a clear differentiation of these may be crucial for any evaluation of the role of representations in cognition and in cognitive theory.

In seeking to understand the extraordinary persistence and recalcitrance of the problems of intentionality, it is instructive to focus attention on one particular facet of the issue. The question of misrepresentation has been discussed recently as a puzzling aspect of the overall problem of the semantics of mental representation (Fodor 1984, 1994, Dretske 1994) and I propose to explore this issue as a loose thread which may be pulled to unravel the rest of the tangled ball.

Robert Cummins [(1996) Representations, targets and attitudes, Cambridge, MA: Bradford/MIT, p. 1] has characterized the vexed problem of mental representation as "the topic in the philosophy of mind for some time now." This remark is something of an understatement. The same topic was central to the famous controversy between Nicolas Malebranche and Antoine Arnauld in the 17th century and remained central to the entire philosophical tradition of "ideas" in the writings of Locke, Berkeley, Hume, Reid and Kant. However, the scholarly, (...) exegetical literature has almost no overlap with that of contemporary cognitive science. I show that the recurrence of certain deep perplexities about the mind is a systematic and pervasive pattern arising not only throughout history, but also in a number of independent domains today such as debates over visual imagery, symbolic systems and others. Such historical and contemporary convergences suggest that the fundamental issues cannot arise essentially from the theoretical guise they take in any particular case. (shrink)

An introduction to the science and philosophy of mental imagery.

Until a few years ago, Cognitive Science was firmly wedded to the notion that cognition must be explained in terms of the computational manipulation of internal representations or symbols. Although many people still believe this, the consensus is no longer solid. Whether it is truly threatened by connectionism is, perhaps, controversial, but there are yet more radical approaches that explicitly reject it. Advocates of "embodied" or "situated" approaches to cognition (e.g., Smith, 1991; Varela _et al_ , 1991, Clancey, 1997) argue (...) that thought cannot be understood as entirely internal. Furthermore, it is argued that autonomous robots can be designed to behave more intelligently if representationalist programming techniques are avoided (Brooks, 1991), and that the way our brains control our behavior is better understood in terms of chaos and dynamical systems theory rather than as any sort computation (e.g., Freeman & Skarda, 1990; Van Gelder & Port, 1995; Van Gelder, 1995; Garson, 1996).

This chapter examines the similarities and differences between physical, psychological and virtual realities, and challenges some conventional, implicitly dualist assumptions about how these relate to each other. Virtual realities are not easily understood in either dualist or materialist reductive terms, as they exemplify the reflexive nature of perception. The chapter summarises some of the evidence for this “reflexive model”—and examines some of its consequences for the “hard” problem of consciousness. The chapter then goes on to consider how these realities might (...) relate to some grounding reality or thing-itself, and considers some of the personal and social consequences of becoming increasingly immersed in virtual realities. Although this chapter was published in 1998 and develops work published in 1990, it presents a form of “radical externalism” that anticipates many themes in current (2006) internalism versus externalism debates about the nature of mind. It is also relevant to an understanding of virtual reality “presence.”. (shrink)

This paper examines the nomic covariationist strategy of using idealization to define representation. While the literature has focused upon the possibility of defining ideal conditions for perception, I argue that nomic covariationist appeals to idealization are pseudoscientific and contrary to a foundational and empirically well-supported methodological presupposition in cognitive science. Moreover, one major figure in this camp fails to come to grips with its role and its problems in mainstream science. Thus he forwards a false dichotomy of the sciences and (...) treats idealization as a blank check written by scientists on an unknown bank. Finally, I consider and reject alternative formulations of the nomic covariationist's idealization strategy. (shrink)

Jerry Fodor begins chapter one of The Language of Thought with two claims. The first claim is that “[T]he only psychological models of cognitive processes that seem remotely plausible represent such processes as computational.” The second claim is that “[C]omputation presupposes a medium of computation: a representational system.” Together these two claims suggest one of the central theses of many contemporary representationalist theories of mind, viz. that the only remotely plausible psychology that could succeed in explaining the intentionally characterized abilities (...) and activities of sentient creatures must refer to computationally related representations. Although “[R]emotely plausible theories are”, according to Fodor, “better than no theories at all”, representationalism is not universally regarded as a “remotely plausible theory”. In what follows I will consider what many people believe to be a significant problem facing representationalism. I will then examine two different ways that this problem can be resolved, one based on the writings of Daniel Dennett, the other on ideas found in the later writings of Wittgenstein. I will conclude that although the resolution based on Dennett’s writings fails, a resolution based on ideas found in the later writings of Wittgenstein succeeds. (shrink)

I consider two threats to the idea that on-line intelligent behaviour (the production of fluid and adaptable responses to ongoing sensory input) must or should be explained by appeal to neurally located representations. The first of these threats occurs when extra-neural factors account for the kind of behavioural richness and flexibility normally associated with representation-based control. I show how this anti-representational challenge can be met, if we apply the thought that, to be a representational system, an action-oriented neural system must (...) not only be the source of at least some of the observed behavioural richness and flexibility, it must also feature two architectural traits, namely arbitrariness and homuncularity. Unfortunately, however, this solution opens the door to our second threat to representation. The homuncularity condition will not be met by any system in which the causal contribution of each component is massively context-sensitive and variable over time. I end by discussing the empirical bet that biological nervous systems will not exhibit this style of causation. (shrink)

More than ever, it is in vogue to argue that no norms either play a role in or directly follow from the theory of mental content. In this paper, I present an intuitive theory of intentionality (including a theory of mental content) on which norms are constitutive of the intentional properties of attitude and content in order to show that this trend is misguided. Although this theory of intentionality—the teleological theory of intentional representation—does involve a commitment to representational norms, these (...) norms are not problematic in the way critics have suggested they would be. In particular, these norms do not guide thinking by motivating intentional agents to (intentionally) accord with them; as a result, no obvious vicious regress threatens the theory. In the final section of this paper, I argue that accepting this teleological theory of intentionality need not commit one to thinking that intentionality is the product of natural selection.

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.

Ideas play at least two roles in Locke's theory of the understanding. They are constituents of ‘propositions,’ and some of them ‘represent’ the qualities and sorts of surrounding bodies. I argue that each role involves a distinct kind of intentional directedness. The same idea will in general be an ‘idea of’ two different objects, in different senses of the expression. Identifying Locke's scheme of twofold ‘ofness’ reveals a common structure to his accounts of simple ideas and complex ideas of substances. (...) A consequence is a distinction among substance sorts parallel to one of his distinctions between primary and secondary qualities. (shrink)

Intentionality is a property of an important class of things: things that represent, or are about something. Thus a belief or sentence or story is about something, a painting or photo is of something, a sign is a sign of something, and a desire is a desire for something. These disparate things all display intentionality. They have content; they represent some state of affairs beyond themselves. The represented state of affairs need not be actual, and is not in the cases (...) of false belief, unfulfilled desire, or Salvadore Dali painting. (shrink)

The traditional understanding of analyticity in terms of concept containment is revisited, but with a concept explicitly understood as a certain kind of mental representation and containment being read correspondingly literally. The resulting conception of analyticity avoids much of the vagueness associated with attempts to explicate analyticity in terms of synonymy by moving the locus of discussion from the philosophy of language to the philosophy of mind. The account provided here illustrates some interesting features of representations and explains, at least (...) in part, the special epistemic status of analytic judgments. (shrink)
