In this paper, I propose a new way of understanding the space of possibilities in the field of mental content. The resulting map assigns separate locations to theories of content that have generally been lumped together on the more traditional map. Conversely, it clusters together some theories of content that have typically been regarded as occupying opposite poles. I make my points concrete by developing a taxonomy of theories of mental content, but the main (...) points of the paper concern not merely how to classify, but how to understand, the theories. Also, though the paper takes theories of mental content as a case study, much of the discussion is applicable to theories of other phenomena. To a first approximation, the difference between the traditional and the proposed taxonomies turns on whether we classify theories of content by, on the one hand, their implications for a non-redundant supervenience base for content facts (i.e., for facts about what contents thoughts have) or, on the other, by their constitutive accounts of content. By a "constitutive account," I mean the kind of elucidation of the nature of a phenomenon that theorists have tried to give for, for example, knowledge, justice, personal identity, consciousness, convention, heat, and limit. The tendency to taxonomize by supervenience base is encouraged, I suggest, by a failure to keep clearly in view a distinction between constitutive and modal determination. Many philosophers would accept that a constitutive account cannot be captured in purely modal terms. Giving a constitutive account is not the same as specifying modally necessary and sufficient conditions. Nevertheless, philosophers often try to cash constitutive claims in modal terms. A case in point is that theories of content tend to be conceptualized in terms of the theories' implications for a supervenience base for content facts. My thesis goes beyond the by-now somewhat familiar proposition that not all modal determinants of a phenomenon are constitutive determinants. One who has taken that point on board might nevertheless conceive of a philosophical account as an attempt to specify constitutive determinants of the target phenomenon that make up a non-redundant supervenience base for the phenomenon. Shoehorning a philosophical account into this form leaves out elements that are modally redundant, but may be explanatorily or ontologically significant. For example, when a constitutive account has multiple levels, the different levels will typically be modally redundant. Formulating the account as a specification of a supervenience base of constitutive determinants will therefore flatten the account into a single level. Many of my arguments can be illustrated by considering the place of normativity in the theory of content. The new taxonomy gives a distinct niche to normative theories of content - theories that explain a thought's having a certain content at least in part in terms of the obtaining of normative facts. By contrast, on a traditional map, normative theories are invisible as such because normative facts supervene on non-normative ones. (shrink)

Since the 1960's, work in the analytic tradition on the nature of mental and linguistic content has converged on the views that social facts about public language meaning are derived from facts about the thoughts of individuals, and that these thoughts are constituted by properties of the internal states of agents. I give a two-part argument against this picture of intentionality: first, that if mental content is prior to public language meaning, then a view of (...) class='Hi'>mental content much like the causal-pragmatic theory presented by Robert Stalnaker in Inquiry must be correct; second, that the causal-pragmatic theory is false. I conclude with some positive suggestions regarding alternative solutions to the `problem of intentionality.'. (shrink)

One central issue concerning philosophical methodology is this: what concepts should go into our philosophical toolbox? That is to say, what notions are appropriate to rely on in doing philosophy? This issue is relevant not only to how we should go about addressing philosophical problems but also how we’re to formulate those problems in the first place. There is a burgeoning literature on the notion of grounding. I’m a proponent of grounding – I think the notion of grounding is coherent (...) and theoretically useful.1 Supposing that the notion of grounding belongs in our philosophical toolbox, what consequences might this have for familiar philosophical problems? In this chapter I focus on what Jackson calls placement problems, problems concerning how the manifest facts “fit into” the world given that the world is ultimately physical in nature. If we formulate placement problems in terms of grounding, we should expect new possibilities to open up with respect to how to solve them. My goal in this chapter is to show that this is precisely what happens with respect to the content placement problem, the problem of how to fit facts concerning mental content into the actual world given that it’s ultimately physical in nature.

Some mental states are about themselves. Nothing is a cause of itself. So some mental states are not about their causes; they are about things distinct from their causes. If this argument is sound, it spells trouble for causal theories of mental content—the precise sort of trouble depending on the precise sort of causal theory. This paper shows that the argument is sound (§§1-3), and then spells out the trouble (§4).

In Connectionism and the Philosophy of Psychology, Horgan and Tienson (1996) argue that cognitive processes, pace classicism, are not governed by exceptionless, “representation-level” rules; they are instead the work of defeasible cognitive tendencies subserved by the non-linear dynamics of the brain’s neural networks. Many theorists are sympathetic with the dynamical characterisation of connectionism and the general (re)conception of cognition that it affords. But in all the excitement surrounding the connectionist revolution in cognitive science, it has largely gone unnoticed that connectionism (...) adds to the traditional focus on computational processes, a new focus – one on the vehicles of mental representation, on the entities that carry content through the mind. Indeed, if Horgan and Tienson’s dynamical characterisation of connectionism is on the right track, then so intimate is the relationship between computational processes and representational vehicles, that connectionist cognitive science is committed to a resemblance theory of mental content.

Standard interpretations of Kant’s transcendental idealism take it as a commitment to the view that the objects of cognition are structured or made by conditions imposed by the mind, and therefore to what Van Cleve calls “honest-to-God idealism”. Against this view, many more recent investigations of Kant’s theory of representation and cognitive significance have been able to show that Kant is committed to a certain form of Mental Content Externalism, and therefore to the realist view that the objects (...) involved in experience and empirical knowledge are mind-independent particulars. Some of these recent interpreters have taken this result to demonstrate an internal incompatibility between Kant‘s transcendental idealism and his own model of cognitive content and the environmental conditions of empirical knowledge. Against this suggestion, this article argues that, while Kant’s theory of content is indeed best construed as externalist, an adequately adjusted form of transcendental idealism is not only compatible with this externalism, but in fact supports it. More generally, the article develops the position that mental content externalism cannot force the adoption of metaphysical realism. (shrink)

Recent philosophy of psychology has seen the rise of so-called "dual-component" and "two-dimensional" theories of mental content as what I call a "Middle Way" between internalism (the view that contents of states like belief are "narrow") and externalism (the view that by and large, such contents are "wide"). On these Middle Way views, mental states are supposed to have two kinds of content: the "folk-psychological" kind, which we ordinarily talk about and which is wide; and some (...) non-folk-psychological kind which is narrow. Jerry Fodor is responsible for one of the most influential arguments that we need to believe in some such non-folk-psychological kind of content. In this paper I argue that the ideas behind Fodor's premises are mutually inconsistent - so it would be irrational to believe in a Middle Way theory of mental content no matter how many of Fodor's premises you find plausible. Common opinion notwithstanding, we have to choose between internalism and externalism, full-stop. (shrink)

Tyler Burge's critique of individualistic conceptions of mental content is well known.This paper employs a novel strategy to defend a strong form of Burge's conclusion. The division of epistemic labor rests on the possibility of language-mediated transactions, such as asking for something in a store and getting it. The paper shows that any individualistic conception of content will render such transactions unintelligible.

This paper has two interrelated aims. The primary aim is to specify the character of philosophical theories of mental content that are usually classified as ‘Causal Theories of Intentionality’, ‘Causal Theories of Representation’, or ‘Causal Theories of Mental Content’ (CTs). More specifically, the aim is to characterize the role and place of causation in philosophical reflections on the nature of mental content, as suggested by theories of this kind. Elucidation of the role of the (...) concept of causation in CTs requires examining the philosophical background against which versions of CTs are proposed; therefore the second aim of this paper is to clarify the link between CTs and the two philosophical theories that accompany it: the doctrine of philosophical naturalism (PN) and the representational theory of mind (RTM). Clarification of the relationship between the three theories is not only necessary for an adequate specification of the causal component that plays a central role in CTs, and so for a better understanding of CTs themselves; it also shows how the role that causation plays in CTs implies a genuinely relational conception of intentionality.

The thesis of this paper is that the causal theory of mental content (hereafter CT) is incompatible with an elementary fact of perceptual psychology, namely, that the detection of distal properties generally requires the mediation of a “theory.” I shall call this fact the nontransducibility of distal properties (hereafter NTDP). The argument proceeds in two stages. The burden of stage one is that, taken together, CT and the language of thought hypothesis (hereafter LOT) are incompatible with NTDP. The (...) burden of stage two is that acceptance of CT requires acceptance of LOT as well. It follows that CT is incompatible with NTDP. I organize things in this way in part because it makes the argument easier to understand, and in part because the stage-two thesis—that CT entails LOT—has some independent interest and is therefore worth separating from the rest of the argument.

In this paper, I attempt to map out the 'logical geography' of the territory in which issues of mental content and of personal identity meet. In particular, I investigate the possibility of combining a psychological criterion of personal identity with an externalist theory of content. I argue that this can be done, but only by accepting an assumption that has been widely accepted but barely argued for, namely that when someone switches linguistic communities, the contents of their (...) thoughts do not change immediately, but only after the person becomes integrated within the new linguistic community. I also suggest that recent work on personal identity, notably by Derek Parfit, has tacitly assumed internalism regarding mental content. I do not intend to argue for either externalism or a psychological criterion. My aim is merely to explicate the issues involved in making them compatible. (shrink)

Cognitive ethology is the comparative study of animal cognition from an evolutionary perspective. As a sub-discipline of biology it shares interest in questions concerning the immediate causes and development of behavior. As a part of ethology it is also concerned with questions about the function and evolution of behavior. I examine some recent work in cognitive ethology, and I argue that the notions of mental content and representation are important to enable researchers to answer questions and state generalizations (...) about the function and volution of behavior.

Defends the supervenience of mental content under an externalist view of both contents and the supervenience base.

According to ‘internalism’, what mental states people are in depends wholly on what obtains inside their heads. This paper challenges that view without relying on arguments about the identity‐conditions of concepts that make up the content of mental states. Instead, it questions the internalist’s underlying assumption that, in Searle’s words, “the brain is all we have for the purpose of representing the world to ourselves”, which neglects the fact that human beings have used their brains to devise (...) methods for extending and enhancing the brain’s own functions, in particular for storing information externally. Although Popper draws attention to this fact, he fails to grasp its psychological implications, concluding instead that there can be knowledge “without a knowing subject”, and so repeating the internalist’s mistake. With equal justice one can conclude, absurdly, that there are ownerless plans, resolutions and shopping‐lists. The paper goes on to meet possible internalist counter‐arguments. (shrink)

This paper assumes an exteernalist view of content, and argues that the Twin Earth considerations do not establish that content properties relationally individuated do not strongly supervene on micro-physical properties, on the basis that the relevant physical supervenience basis might well be equally relationally specified. For all that we know, it is reasonable to ascribe causal efficacy to broad contents, even when we accept the supervenience constraint in its strongest form.

I consider whether one particular anti-individualist claim, the doctrine of object-dependent thoughts (DODT), is compatible with the Principle of Privileged Access, or PPA, which states that, in general, a subject can have non-empirical knowledge of her thought contents. The standard defence of the compatibility of anti-individualism and PPA emphasises the reliability of the process which produces a subject's second order beliefs about her thought contents. I examine whether this defence can be applied to DODT, given that DODT generates the possibility (...) of illusions of thought. Drawing on general epistemological literature, I distinguish several senses of reliability, and argue that in the relevant sense-'global reliability'-DODT does sometimes threaten reliability and hence PPA.

The aim of this paper is to argue that the phenomenal similarity between perceiving and visualizing can be explained by the similarity between the structure of the content of these two different mental states. And this puts important constraints on how we should think about perceptual content and the content of mental imagery.

Externalism with regard to mental content says that in order to have certain types of intentional mental states (e.g. beliefs), it is necessary to be related to the environment in the right way.

I develop several new arguments against claims about "cognitive phenomenology" and its alleged role in grounding thought content. My arguments concern "absent cognitive qualia cases", "altered cognitive qualia cases", and "disembodied cognitive qualia cases". However, at the end, I sketch a positive theory of the role of phenomenology in grounding content, drawing on David Lewis's work on intentionality. I suggest that within Lewis's theory the subject's total evidence plays the central role in fixing mental content and (...) ruling out deviant interpretations. However I point out a huge unnoticed problem, the problem of evidence: Lewis really has no theory of sensory content and hence no theory of what fixes evidence. I suggest a way of plugging this hole in Lewis's theory. On the resulting theory, which I call " phenomenal functionalism", there is a sense in which sensory phenomenology is the source of all determinate intentionality. Phenomenal functionalism has similarities to the theories of Chalmers and Schwitzgebel. (shrink)

This paper argues that the normative dimension in mental and semantic content is not a categorical feature of content, but an hypothetical one, relative to the features of the interpretation of thoughts and meaning. The views of Robert Brandom are discussed. The thesis defended in this paper is not interpretationist about thought. It implies that the normative dimension of content arises from the real capacity of thinkers and speakers to self ascribe thoughts to themselves and to (...) reach self knowledge of their own thoughts. (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)

Schellenberg sheds light on the recent debate between Dreyfus and McDowell about the role and nature of concepts in perceptual experience, by considering the following trilemma: (C1) Non-rational animals and humans can be in mental states with the same kind of content when they are perceptually related to the very same environment. (C2) Non-rational animals do not possess concepts. (C3) Content is constituted by modes of presentations and is, thus, conceptually structured. She discusses reasons for accepting and (...) rejecting each of the three claims. By developing a substantive notion of modes of presentation as constituting nonconceptual content, she argues that the trilemma is best resolved by giving up (C3). In doing so, she discusses the nature of mental content and its relation to bodily skills and conceptual capacities as well as the notion of conceptual and nonconceptual content. (shrink)

I clarify some of the details of the modal theory of function I outlined in Nanay (2010): (a) I explicate what it means that the function of a token biological trait is fixed by modal facts; (b) I address an objection to my trait type individuation argument against etiological function and (c) I examine the consequences of replacing the etiological theory of function with a modal theory for the prospects of using the concept of biological function to explain mental (...) content.

Causal theories of mental content (CTs) ground certain aspects of a concept's meaning in the causal relations a concept bears to what it represents. Section 1 explains the problems CTs are meant to solve and introduces terminology commonly used to discuss these problems. Section 2 specifies criteria that any acceptable CT must satisfy. Sections 3, 4, and 5 critically survey various CTs, including those proposed by Fred Dretske, Jerry Fodor, Ruth Garrett Millikan, David Papineau, Dennis Stampe, Dan Ryder, (...) and the author himself. The final section considers general objections to the causal approach. (shrink)

I scrutinize the argument for why externally individuated mental content might not be causally efficacious in the explanation of an individual's physical movements. I argue that even though externalististically construed mental content might not explain an individual's physical movements, it might nonetheless explain his or her behavior on a componential view of behavior according to which an individual's physical movement is a component of his or her behavior.

Daniel Dennett and Stephen Stich have independently, but similarly, argued that the contents of mental states cannot be specified precisely enough for the purposes of scientific prediction and explanation. Dennett takes this to support his view that the proper role for mentalistic terms in science is heuristic. Stich takes it to support his view that cognitive science should be done without reference to mental content at all. I defend a realist understanding of mental content against (...) these attacks by Dennett and Stich. I argue that they both mistake the difficulty of making content ascriptions precise for the impossibility of doing so. (shrink)

Narrow mental content is a kind of mental content that does not depend on an individual's environment. Narrow content contrasts with “broad” or “wide” content, which depends on features of the individual's environment as well as on features of the individual. It is controversial whether there is any such thing as narrow content. Assuming that there is, it is also controversial what sort of content it is, what its relation to ordinary or (...) “broad” content is, and how it is determined by the individual's intrinsic properties. (shrink)

I argue that the normative dimension in mental content does not figure in the content as a direct feature of this content. But I do not take is as an extrinsic feature due to the properties of our ascriptions either. I suggest that the normativity has to do with the possibility of self attribution of mental states. The views of Robert Brandom are examined in this respect.

Externalism says that many ordinary mental contents are constituted by relations to things outside the mental subject’s head. An infl uential objection says that externalism is incompatible with our commonsense belief in mental causation, because such extrinsic relations cannot play the important causal role in producing behavior that we ordinarily think mental content plays.An extremely common response is that it is simply obvious, from examples of ordinary causal processes, that extrinsic relations can play the desired (...) causal role. In this paper I argue that such examples show no such thing, and that the only reason to think they do is to endorse an unacceptable principle concerning the sufficient conditions for causal efficacy. Internalists might be wrong that externalism is incompatible with mental causation; but the most common defense against that allegation should not move us at all. (shrink)

Tyler Burge has in many writings distinguished between mental content externalism based on incorrect understanding and mental content externalism based on partial but not incorrect understanding. Both and have far-reaching implications for analyses of communication and concept possession in various expert-layperson relations, but Burge and his critics have mainly focused on . This article first argues that escapes the most influential objection to . I then raise an objection against Burge’s argument for . The objection focuses (...) on Burge’s claim that a person with a partial understanding of a term in our community expresses our standard concept because he is willing to defer to our standard understanding, while his “Putnamian” twin in a counterfactual community does not. The problem with Burge’s argument for this claim is that he does not consider the possibility that the person in our community and the twin would defer to the same understanding if they were presented with the same alternatives. Drawing from widespread dispositional assumptions about meaning, I argue that Burge must accept that they express the same concept if they would defer to the same understanding. The article closes with an examination on various ways the externalist may attempt to avoid this problem and concludes that none of them succeeds. (shrink)

Brentano and his students were the first to wrestle an Aristotelian perceptual concept, intentionality, into the modern metaphysics of mind. This dissertation recovers theories of Franz Brentano , Kazimierz Twardowski , and Edmund Husserl by appreciating each as an unique attempt to make a modern home for the ancient doctrine of "aboutness." The dissertation corrects a broad range of contemporary misunderstandings and criticisms of Brentano School philosophy, in particular one advanced by Martin Heidegger . ;Brentano's Psychology from an Empirical Standpoint (...) is marked by deep tensions between the doctrine of intentional inexistence and its Comtean positivism; Brentano treated mental contents as Comtean phenomena. Understanding physical phenomena as facts presented by sensations, and as syntactic building-blocks for higher-order mental phenomena, I reject misinterpretations of Brentano as either anti-reductionist or Immanentist. The unstable Brentanian account of intentionality was inherited by his student Twardowski. On the Content and Object of Presentations hoped to shore up Brentano's position with a crisp distinction of mental contents from worldly objects; Twardowski was among the first to attempt to integrate intentionality with a modern representationalism. The result was subjective mental content through which objects in the extra-conscious world are represented, a watershed in the history of representationalisms. Twardowski treated the representational relation as resemblance and mental contents as " quasi pictures," but Twardowski was among the first distinctly 20th Century representationalists, those who treat mental content as extra-conscious. Husserl's solution to Brentano's problem rejected the positivistic phenomena of his teacher and criticized the quasi-pictures of his classmate. The heart of the Logical Investigations account of consciousness is a distinction between two kinds of mental content. The intentional objects of the world at large are our mental contents , the very things that remain fixed while our mental contents fluctuate. Understanding this dynamic relation between two kinds of mental content, I reject readings of the Investigations which treat ideal content as either Fregean or Aristotelian. The recovery of Husserl's notion of ideality, one strategy amongst several in attempts to integrate intentionality with modern metaphysics, abets a defense of early Husserlian phenomenology from one of its most powerful critics.

Internalism about mental content is the view that microphysical duplicates must be mental duplicates as well. This dissertation develops and defends the idea that only a strong version of internalism is compatible with our commonsense commitment to mental causation. ;Chapter one defends a novel necessary condition on a property's being causally efficacious---viz., that any property F that is efficacious with respect to event E cannot be instantiated in virtue of any property G that is itself ceteris (...) paribus sufficient for E---and shows that that necessary condition vindicates the idea that externalism is incompatible with our commonsense commitment to mental causation. ;The internalist's core intuition is that only intrinsic properties can be causally efficacious. Chapter two defends that intuition from the common externalist response that extrinsic properties abound. ;A popular "Middle Way" between externalism and internalism holds that although ordinary, "folk-psychological" contents of prepositional attitudes are extrinsic, there exists some other non-folk-psychological kind of content that is intrinsic. Chapter three argues that Jerry Fodor's influential argument for the Middle Way is incoherent. ;Chapter four identifies a weak but popular grade of internalism, endorsed by John Searle among others, and argues that it is untenable. ;The preceding defense of internalism can be believed only if there is something wrong with the canonical arguments for externalism developed by Hillary Putnam, Tyler Burge, and Saul Kripke. My postscript says what I think is wrong with the canonical externalist arguments: they assume the nonexistence of propositions that are truth-evaluable only relative to particular persons, places, or times; while I argue that our commonsense commitment to mental causation requires at least some such "indexical propositions".

This thesis concerns the content of mental representations. It draws lessons for philosophical theories of content from some empirical findings about brains and behaviour drawn from experimental psychology (cognitive, developmental, comparative), cognitive neuroscience and cognitive science (computational modelling). Chapter 1 motivates a naturalist and realist approach to mental representation. Chapter 2 sets out and defends a theory of content for static feedforward connectionist networks, and explains how the theory can be extended to other supervised networks. (...) The theory takes forward Churchland’s state space semantics by making a new and clearer proposal about the syntax of connectionist networks − one which nicely accounts for representational development. Chapter 3 argues that the same theoretical approach can be extended to unsupervised connectionist networks, and to some of the representational systems found in real brains. The approach can also show why connectionist systems sometimes show typicality effects, explaining them without relying upon prototype structure. That is discussed in chapter 4, which also argues that prototype structure, where it does exist, does not determine content. The thesis goes on to defend some unorthodox features of the foregoing theory: that a role is assigned to external samples in specifying syntax, that both inputs to and outputs from the system have a role in determining content, and that the content of a representation is partly determined by the circumstances in which it developed. Each, it is argued, may also be a fruitful way of thinking about mental content more generally. Reliance on developmental factors prompts a swampman-type objection. This is rebutted by reference to three possible reasons why content is attributed at all. Two of these motivations support the idea that content is partly determined by historical factors, and the third is consistent with it. The result: some empirical lessons for philosophical theories of mental content. (shrink)

With the aim of giving a naturalistic foundation to the notion of mental representation, Fred Dretske (1981;1988) has put forward and developed the idea that the relation between a representation and its intentional content is grounded on an informational relation. In this explanatory model, mental representations are conceived of as states of organisms which a learning process has selected to play a functional role: a necessary condition for fulfilling this role is that the organism or some proper (...) part of it (presumably situated in the brain) is a natural indicator of the occurrence of a determinate type of event in the environment of the organism (or in the organism but outside of the proper part serving as the indicator). A state of the organism is a natural indicator of a type of event if and only if it carries information about the occurrence of that type of event. Jerry Fodor (1987) has devised and followed another strategy which consists in considering the relation between a mental representation and its intentional object as a relation of lawful, or nomic, dependence. A representational state of an organism has an objective content in virtue of the existence of a relation of nomic dependence between this state - presumably a property of the brain of the organism - and some objective property in the world. This dependence also creates a regular correlation between the occurrences of representational states of a certain type and the states of affairs whose type is their representational content. Both approaches encounter indeterminacy problems: for each, there exist situations in which the explanatory model chosen - information flow or nomic dependence - does not succeed in selecting, purely on the basis of the constraints characteristic of that model, one out of several potential contents for a given representational state. In such cases, that state is related to more than one type of events in accordance with the informational or nomic constraints imposed by those theories. In what follows, I examine an attempt by Pierre Jacob (1997) to solve two problems of indeterminacy threatening the informational theory of mental representation. According to Jacob, one of these problems can be solved with the help of the distinction between the source which is the target of the information and the channel over which the information is transmitted, whereas the solution to the other problem requires the introduction of the concept of function. I shall begin with a consideration of the distinction, with respect to a situation of information transmission, between the source and the channel. I argue that both the source and the channel, and thus the information transmitted, depend not only on the external situation which characterises the source, the channel and the receiving organism, but also on the previous knowledge and the informational needs of the receiver. I then try to show that this relativity of information undermines the solution Jacob proposes to one of the problems of indeterminacy of representational content. Finally, I examine the possibility considered by Dretske and Jacob to solve this 'problem of the reference class' due to the mentioned relativity of information, by grounding the flow of information on lawful dependence instead of statistical dependence. I shall propose two arguments showing first that these two groundings are not equivalent and second that nomic dependence is inappropriate as a grounding for information flow. I conclude by suggesting that the problem of the reference class can be solved within the framework of the informational approach, on the condition of enriching it with functional considerations.

Belief and Meaning is a philosophical treatment of intentionality. It offers an original, logical and convincing account of intentional content which is local and contextual and which takes issues with standard theories of meaning.

Introduction: representationalismMost theorists of cognition endorse some version of representationalism, which I will understand as the view that the human mind is an information-using system, and that human cognitive capacities are representational capacities. Of course, notions such as ‘representation’ and ‘information-using’ are terms of art that require explication. As a first pass, representations are “mediating states of an intelligent system that carry information” (Markman and Dietrich 2001, p. 471). They have two important features: (1) they are physically realized, and so (...) have causal powers; (2) they are intentional, in other words, they have meaning or representational content. This presumes a distinction between a representational vehicle—a physical state or structure that has causal powers and is responsible for producing behavior—and its content. Consider the following characterization of a device that computes the addition functionReaders will recognize the similarity t. (shrink)

David’s epistemic understanding of two-dimensional semantics has these two features. First, although he considers at least two construals of epistemically possible worlds, on one of them they are centered metaphysically possible worlds. Second, David intends epistemic two-dimensional semantics to yield a theory of propositional-attitude content, as well as having application to the semantics of natural language expressions. These two features come together in David’s “The Components of Content,” where he deploys the apparatus of epistemic two-dimensional semantics to provide (...) an account of propositional-attitude content, and where, for reasons of simplicity and familiarity, epistemically possible worlds are taken to be centered metaphysically possible worlds. My talk is about this account of content. (shrink)
