In this paper, I claim that the personal/subpersonal distinction is first and foremost a distinction between two kinds of psychological theory or explanation: it is only in this form that we can understand why the distinction was first introduced, and how it continues to earn its keep. I go on to examine the different ontological commitments that might lead us from the primary distinction between personal and subpersonal explanations to a derivative distinction between personal and subpersonal states. I argue that (...) on one of the most common metaphysical interpretations of the explanatory distinction, talk of a distinction between personal and subpersonal states simply makes no sense. When people insist on applying the personal/subpersonal terminology to psychological states, I allow that they are often making a genuine distinction, but one that it is best understood in terms of Stich's (1978) distinction between doxastic and subdoxastic states. I end the paper by considering some other common misinterpretations of the personal/subpersonal distinction, such as those involving consciousness, normativity, or autonomy. (shrink)

Propositionalism is the view that all intentional states are propositional states, which are states with a propositional content, while objectualism is the view that at least some intentional states are objectual states, which are states with objectual contents, such as objects, properties, and kinds. This paper argues that there are two distinct ways of understanding propositionalism and objectualism: (1) as views about the deep nature of the contents of intentional states, and (2) as views about the superficial character of the (...) contents of intentional states. I argue that we should understand the views in the second way. I also argue that the propositionalism debate is fairly independent from debates over the deep nature of intentionality, and that this has implications for arguments for propositionalism and objectualism from claims about the nature of intentional content. I close with a short discussion of how related points apply to the debate over singular content. (shrink)

The paper examines some of the questions emerging from the debate on mindreading regarding Quine’s legacy and contribution to a new agenda on the issue. Since mindreading is an exercise in folk-psychology, a) which role folk psychology has to play according to Quine? b) was Quine’s account of mindreading closer to theory-theory, simulation theory or hybrid theory? c) was Quine a rationality theorist? d) are hybrid-theory and rationality theory incompatible as many would suggest? On the score of the answers to (...) these questions, the paper tries to suggest a Quinean inspired blend of rationality-based and hybrid view-based strategies to explain mindreading. (shrink)

Information theoretic semantics proposes to construe predicate reference in terms of nomological relations between distal properties and properties of representational mental events. Research on the model has largely concentrated on the problem of choosing the nomological relation in terms of which distal properties are to be singled out. I argue that, in addition to this, an information theoretic account has to provide a specification of which properties of representational mental events will play a role in determining reference, qua bearers of (...) nomological relations. I contend that this task poses a serious additional challenge to the viability of the model. (shrink)

An important class of teleological theories cannot explain the representational content of visual states because they fail to address the relationship between the world, projected retinal stimuli, and perception. A different approach for achieving a naturalized theory of visual content is offered that rejects the traditional internalism/externalism debate in favor of what is termed “empirical externalism.” This position maintains that, while teleological considerations can underwrite a broad understanding of representation, the content of visual representation can only be determined empirically according (...) to accumulated past experience. A corollary is that a longstanding problem concerning the indeterminacy of visual content is dissolved. (shrink)

How are permutation arguments for the inscrutability of reference to be formulated in the context of a Davidsonian truth-theoretic semantics? Davidson takes these arguments to establish that there are no grounds for favouring a reference scheme that assigns London to “Londres”, rather than one that assigns Sydney to that name. We shall see, however, that it is far from clear whether permutation arguments work when set out in the context of the kind of truth-theoretic semantics which Davidson favours. The principle (...) required to make the argument work allows us to resurrect Foster problems against the Davidsonian position. The Foster problems and the permutation inscrutability problems stand or fall together: they are one puzzle, not two. (shrink)

Inscrutability arguments threaten to reduce interpretationist metasemantic theories to absurdity. Can we find some way to block the arguments? A highly influential proposal in this regard is David Lewis’ ‘ eligibility ’ response: some theories are better than others, not because they fit the data better, but because they are framed in terms of more natural properties. The purposes of this paper are to outline the nature of the eligibility proposal, making the case that it is not ad hoc, but (...) instead flows naturally from three independently motivated elements; and to show that severe limitations afflict the proposal. In conclusion, I pick out the element of the eligibility response that is responsible for the limitations: future work in this area should therefore concentrate on amending this aspect of the overall theory.

Optimising the 4E revolution in cognitive science arguably requires the rejection of two guiding commitments made by orthodox thinking in the field, namely that the material realisers of cognitive states and processes are located entirely inside the head, and that intelligent thought and action are to be explained in terms of the building and manipulation of content-bearing representations. In other words, the full-strength 4E revolution would be secured only by a position that delivered externalism plus antirepresentationalism. I argue that one (...) view in 4E space—extended functionalism—is appropriately poised to deliver externalism but not antirepresentationalism. By contrast, in the case of a competing 4E view—radical enactivism—even if that view can deliver antirepresentationalism, its pivotal notion of extensiveness falls short of establishing externalism. These conclusions are justified via an examination of, and by responding critically to, certain key arguments offered in support of their view by the radical enactivists. (shrink)

Moore's paradox is a paradox in which certain kinds of belief or assertion, such as a belief that ?it is raining and I do not believe that it is raining?, are irrational despite involving no obvious contradiction in what is believed. But is there a parallel paradox involving other kinds of attitude, in particular desire? I argue that certain kinds of desire would be irrational to have for similar, distinctive reasons that having Moorean beliefs would be irrational to have. Hence, (...) I argue that such desires, a desire that ?one have a particular desire that was frustrated? or a desire that ?some state of affairs obtain about which one was indifferent?, are a parallel Moorean paradox of desire. I further argue that this analogous paradox has implications for practical reasoning, in particular by presenting a problem for instrumentalism about the objects of desire. (shrink)

In this paper, I explore the consequences of the thesis that externalism and internalism are (possibly, but as we will see not necessarily, opposite) metaphysical doctrines on the individuation conditions of a thought. If I am right, this thesis primarily entails that at least some naturalist positions on the ontology of the mind, namely the reductionistic ones, are hardly compatible with both externalism and a version of internalism so conceived, namely relational internalism. Indeed, according to both externalism and relational internalism, (...) intentionality constitutes (or at least grounds) the relational content property providing the individuation conditions of a thought, as a relation to an outer or to an inner object respectively. Yet since intentionality turns out to be a modal, hence a nonnatural, property, both externalism and relational internalism deny to thoughts at least token-identity with physical states. Finally, I will give some support to the idea that externalism and internalism must be interpreted as doctrines on the individuation conditions of a thought. (shrink)

In the present paper, I shall argue that disjunctively construed naïve realism about the nature of perceptual experiences succumbs to the empirically inspired causal argument. The causal argument highlights as a first step that local action necessitates the presence of a type-identical common kind of mental state shared by all perceptual experiences. In a second step, it sets out that the property of being a veridical perception cannot be a mental property. It results that the mental nature of perceptions must (...) be exhausted by the occurrence of inner sensory experiences that narrowly supervene on the perceiver. That is, empirical objects fail directly to determine the perceptual consciousness of the perceiver. The upshot is that not only naïve realism, but also certain further forms of direct realism have to be abandoned. (shrink)

In Representation Reconsidered , William Ramsey suggests that the notion of structural representation is posited by classical theories of cognition, but not by the ‘newer accounts’ (e.g. connectionist modeling). I challenge the assertion about the newer accounts. I argue that the newer accounts also posit structural representations; in fact, the notion plays a key theoretical role in the current computational approaches in cognitive neuroscience. The argument rests on a close examination of computational work on the oculomotor system.

It is widely assumed that emotions have particular intentional objects. This assumption is consistent with the way that we talk: when we attribute states of anger, we often attribute anger at someone, or at something. It is also consistent with leading theories of emotion among philosophers and psychologists, according to which emotions are like judgments or appraisals. However, there is evidence from the social psychology literature suggesting that this assumption is actually false. I will begin by presenting a criterion for (...) determining whether a mental state has a particular object. It is not sufficient for that state to be caused by an object or by a representation of a given object—the state must influence the subject’s thought and behavior in ways that are specific to that object. I will present evidence that emotions fail this test, and describe some of the reasons why we persistently attribute objects to our emotions. My view may seem untenable, because the literature on various aspects of emotional life such as normativity, linguistic expression, and behavioral influence consistently appeals to intentional objects. I will conclude by presenting a sketch of how I could address this concern. (shrink)

Do we think in a language-like format? Taking the marker of language-like formats to be the property of unconstrained systematicity, this paper considers the following master argument for the claim that we do: language is unconstrainedly systematic, if language is unconstrainedly systematic then so is thought, so thought is unconstrainedly systematic. It is easy to feel that there is something right about this argument, that there will be some way of filling in its details that will vindicate the idea that (...) our thought must be unconstrainedly systematic given that the language in which we express it is. Clearly, however, the second premise needs support—we need a principled reason for moving from the unconstrained systematicity of language to the unconstrained systematicity of thought. This paper gives three passes at formulating such a principle. This turns out to be much harder than it might seem. We should, I conclude, resist falling too easily for the lure of this master argument for the language-like format of thought. (shrink)

Philip Pettit has advocated a “looks as powers” theory as an alternative to theories that rely on instances of qualia in their account of looking red. Andy Clark has offered a similar view. If these accounts are successful, the Hard Problem is moribund. This paper asks how red comes into cases of something’s looking red to someone. A likely suggestion leads to a conundrum for LAPT: the physical complexity that it attributes to the property red is not evident in experience, (...) yet the view requires manifestness of that very property. Attempts to avoid this difficulty only lead to other problems. LAPT thus fails to provide a solution to the HP. (shrink)

This article considers three views about which properties are genuine. According to the first view, we should look to successful commonsense and scientific explanations in determining which properties are genuine. On this view, predicates that figure in such explanations thereby pick out genuine properties. According to the second view, the only predicates that pick out genuine properties are those that figure in our best scientific explanations. On this view, predicates that figure in commonsense explanations pick out genuine properties only if (...) such explanations are vindicated by the sciences. According to the third view, the only genuine properties are the fundamental, microphysical ones. On this view, although there are “higher-level” predicates that figure in true commonsense and scientific explanations, there are no “higher-level” properties corresponding to such predicates. The article argues that the third view is superior to the others. (shrink)

This paper is about conceptual engineering. Specifically, it discusses a common objection to CE, which I call the Discontinuity Objection. According to the Discontinuity Objection, CE leads to problematic discontinuities in subject and/or inquiry – making it philosophically uninteresting or irrelevant. I argue that a conceptual engineer can dismiss the Discontinuity Objection by showing that the pre-engineering concept persists through the proposed changes. In other words, the Discontinuity Objection does not apply if the proposal involves identity-preserving changes. Two existing views (...) on identity-preserving changes are considered and rejected. I then argue that an identity-preserving conceptual change is one that allows the concept to continue to perform its function. A concept’s function is its job, its point and purpose, its role in a conceptual repertoire. In a slogan: Preserve a concept’s function, and you preserve the concept itself; preserve the concept, and you preserve the subject. The paper concludes by discussing some implications of this view.

A substantial literature supports the attribution of intentional states such as beliefs and desires to groups. But within this literature, there is no substantial account of group concepts. Since on many views, one cannot have an intentional state without having concepts, such a gap undermines the cogency of accounts of group intentionality. In this paper I aim to provide an account of group concepts. First I argue that to fix the semantics of the sentences groups use to make their decisions (...) or express their beliefs, we need to appeal to a conventional semantics like that of Lewis. I then argue that the same reasons we have for taking group intentional states to be irreducible to the intentional states of their members apply also to the terms fixed by a conventional semantics. It follows that the meanings of terms in the sentences expressing a group's intentional states are also fixed by facts about the group, not its members. And recognizing this, I argue, amounts to attributing concepts to groups. Finally, I discuss a real-life example of a group concept—the meaning of ‘meter’ as fixed by the International Bureau of Weights and Measurements—and I discuss the upshot of these considerations for the question of social externalism about concepts.

When it comes to applying computational theory to the problem of phenomenal consciousness, cognitive scientists appear to face a dilemma. The only strategy that seems to be available is one that explains consciousness in terms of special kinds of computational processes. But such theories, while they dominate the field, have counter-intuitive consequences; in particular, they force one to accept that phenomenal experience is composed of information processing effects. For cognitive scientists, therefore, it seems to come down to a choice between (...) a counter-intuitive theory or no theory at all. We offer a way out of this dilemma. We argue that the computational theory of mind doesn't force cognitive scientists to explain consciousness in terms of computational processes, as there is an alternative strategy available: one that focuses on the representational vehicles that encode information in the brain. This alternative approach to consciousness allows us to do justice to the standard intuitions about phenomenal experience, yet remain within the confines of cognitive science. (shrink)

John Searle’s Chinese Room Argument purports to demonstrate that syntax is not sufficient for semantics, and, hence, because computation cannot yield understanding, the computational theory of mind, which equates the mind to an information processing system based on formal computations, fails. In this paper, we use the CRA, and the debate that emerged from it, to develop a philosophical critique of recent advances in robotics and neuroscience. We describe results from a body of work that contributes to blurring the divide (...) between biological and artificial systems; so-called animats, autonomous robots that are controlled by biological neural tissue and what may be described as remote-controlled rodents, living animals endowed with augmented abilities provided by external controllers. We argue that, even though at first sight, these chimeric systems may seem to escape the CRA, on closer analysis, they do not. We conclude by discussing the role of the body–brain dynamics in the processes that give rise to genuine understanding of the world, in line with recent proposals from enactive cognitive science.

I use an old challenge to motivate a new view. The old challenge is due to variation in our perceptions of secondary qualities. The challenge is to say whose perceptions are accurate. The new view is about how we manage to perceive secondary qualities, and thus manage to perceive them accurately or inaccurately. I call it perceptual structuralism. I first introduce the challenge and point out drawbacks with traditional responses. I spend the rest of the paper motivating and defending a (...) structuralist response. While I focus on color, both the challenge and the view generalize to the other secondary qualities. (shrink)

Abstract: Despite all the critical scrutiny they have received recently, contextualist views in philosophy are still not well understood. Neither contextualists nor their opponents have been entirely clear about what contextualist theses amount to and what they are based on. In this article I show that there are actually two kinds of contextualist view that rest on two very different semantic phenomena, namely, semantic incompleteness and semantic indeterminacy . I explain how contextualist approaches can be used to dissolve certain debates (...) in philosophy. According to such approaches, the same philosophical thesis can be correctly endorsed in some contexts and correctly denied in others: it is thus pointless to seek a context-independent solution to debates about this thesis. My purpose is not to defend particular contextualist views but to lay out the general framework on which they rest: this allows us to see more clearly the similarities and differences among contextualist views defended in various areas of philosophy.

What is a concept? Philosophers have given many different answers to this question, reflecting a wide variety of approaches to the study of mind and language. Nonetheless, at the most general level, there are two dominant frameworks in contemporary philosophy. One proposes that concepts are mental representations, while the other proposes that they are abstract objects. This paper looks at the differences between these two approaches, the prospects for combining them, and the issues that are involved in the dispute. We (...) argue that powerful motivations have been offered in support of both frameworks. This suggests the possibility of combining the two. Unlike Frege, we hold that the resulting position is perfectly coherent and well worth considering. Nonetheless, we argue that it should be rejected along with the view that concepts are abstract objects. (shrink)

I outline Brandom’s theory of de re and de dicto belief ascriptions, which plays a central role in Brandom’s overall theory of linguistic communication, and show that this theory offers a surprising, new response to Burge’s (Midwest Stud 6:73–121, 1979) argument for social externalism. However, while this response is in principle available from the perspective of Brandom’s theory of belief ascription in abstraction from his wider theoretical enterprise, it ceases to be available from this perspective in the wider context of (...) his inferential role semantics and his doctrines of scorekeeping and of the expressive role of belief ascriptions in discourse. In this wider context, Brandom’s theory of belief ascriptions implies that Burge’s argument trivially fails to have the disquieting implications for psychological explanations that it is widely taken to have. Yet since this is not trivially so, Brandom’s theory apparently provides a false picture of our practice of interpreting belief ascriptions. I then argue that Brandom might as well accept the alternative picture of interpreting belief ascriptions that Burge’s argument presupposes: even in the context of his overall project, Brandom’s take on our practice of interpreting them does not afford belief ascriptions with the discursive significance Brandom claims they have.

The battle over the proper place of mental representation in cognitive science is often portrayed as a clash between realism and eliminativism. But this simple dichotomy belies the variety of different ontological positions available. This article investigates the various stances that one can adopt toward the ontology of mental representation, and in so doing, shows that eliminativism is in fact best understood as two distinct positions: a posteriori eliminativism and a priori eliminativism. Furthermore, I show that a priori eliminativism faces (...) two crippling challenges. I argue that once we put a priori eliminativism aside, determining the ultimate ontological status of representation can be postponed while we assess its utility across different domains of cognitive science—something all remaining positions can agree on.

In the paper I defend the idea of metametasemantics against the arguments recently presented by Ori Simchen. Simchen attacks the view, according to which metametasemantics incorporating all possible metasemantic accounts is necessary to protect the metasemantic theories from the notorious problem of inscrutability of reference. Simchen claims that if metametasemantics is allowed it ‘absorbs’ metasemantic theories to the extent that it diminishes their explanatory value. Furthermore, in this way Simchen sets up two main metasemantic paradigms i.e. productivism and interpretationism as (...) the rival theories inevitably excluding each other. I endeavour to undermine Simchen’s point by demonstrating that his argumentation mixes up deflationary reading of the predicate ‘is true’ with its substantial reading. Consequently, I demonstrate that accepting metametasemantics does not diminish explanatory value of various metasemantic theories and thus that there is no good reason to forbid metametasemantics. I also argue that even if we ignore the above-mentioned confusion in Simchen’s reasoning, his arguments still fail when considering various problems with the notion of diminishment of explanatory value and because the analogy that his arguments are based on is fairly weak. Eventually, I conclude that metametasemantics does not pose any danger to metasemantics and that it provides a solid ground for developing a theory that benefits from both productivism and interpretationism.

In his groundbreaking Grundlagen, Frege (1884) pointed out that number words like ‘four’ occur in ordinary language in two quite different ways and that this gives rise to a philosophical puzzle. On the one hand ‘four’ occurs as an adjective, which is to say that it occurs grammatically in sentences in a position that is commonly occupied by adjectives. Frege’s example was (1) Jupiter has four moons, where the occurrence of ‘four’ seems to be just like that of ‘green’ in (...) (2) Jupiter has green moons. On the other hand, ‘four’ occurs as a singular term, which is to say that it occurs in a position that is commonly occupied by paradigmatic cases of singular terms, like proper names: (3) The number of moons of Jupiter is four. Here ‘four’ seems to be just like ‘Wagner’ in (4) The composer of Tannhäuser is Wagner, and both of these statements seem to be identity statements, ones with which we claim that what two singular terms stand for is identical. But that number words can occur both as singular terms and as adjectives is puzzling. Usually adjectives cannot occur in a position occupied by a singular term, and the other way round, without resulting in ungrammaticality and nonsense. To give just one example, it would be ungrammatical to replace ‘four’ with ‘the number of moons of Jupiter’ in (1): (5) *Jupiter has the number of moons of Jupiter moons. This ungrammaticality results even though ‘four’ and ‘the number of moons of Jupiter’ are both apparently singular terms standing for the same object in (3). So, how can it be that number words can occur both as singular terms and as adjectives, while other adjectives cannot occur as singular terms, and other singular terms cannot occur as adjectives?

In this article, I argue that the use of scientific models that attribute intentional content to complex systems bears a striking similarity to the way in which statistical descriptions are used. To demonstrate this, I compare and contrast an intentional model with a statistical model, and argue that key similarities between the two give us compelling reasons to consider both as a type of phenomenological model. I then demonstrate how intentional descriptions play an important role in scientific methodology as a (...) type of phenomenal model, and argue that this makes them as essential as any other model of this type.

This paper discusses the nature of consciousness’ intrinsic intentionality from a transcendental-phenomenological viewpoint. In recent philosophy of mind the essentially intentional character of consciousness has become obscured because the latter is predominantly understood in terms of “qualia” or the “what-it-is-like-ness” of mental states and it is hard to see why such subjective “feels”, of all things, could bestow states with objective reference. As the paper attempts to demonstrate, this is an inadequate understanding of consciousness, which should instead be defined in (...) terms of presence. Consciousness essentially takes place as presence-of, i.e., consists in something coming to appearance. This presence-of is not only a fundamental, irreducible phenomenon, but also in a radical sense un-naturalisable. Naturalism only knows “nature”, as the world of objects, and the question of intentionality then seems to be how certain inner-worldly objects can be “representations” of other inner-worldly objects. In fact, no object is ever intrinsically “about” anything. This is exclusively the nature of subjectivity qua consciousness, which is not an object alongside other objects but rather exists as the manifestation of objects. (shrink)

Mohan Matthen has failed to understand the position I develop and defend in “How to Think about Mental Content.” No doubt some of the fault lies with my exposition, though Matthen often misconstrues passages that are clear in context. He construes clarifications and elaborations of my argument to be “concessions.” Rather than dwell too much on specific misunderstandings of my explanatory project and its attendant claims, I will focus on the main points of disagreement.RepresentationalismMy project in the paper is to (...) argue for a particular construal of the role of representational content in computational models of cognition. The view is committed to two kinds of representational content—mathematical content, which characterizes the mathematical function computed by a device and subsumes both biological and artifactual computers, and cognitive content. The latter is determined in part by external, so-called ‘naturalistic’ factors (for example, visual mechanisms represent such distal pro. (shrink)

This paper explores the psychological analogues of a cluster of arguments that have played an important role in motivating a now widespread, reference-based approach in philosophy of language. What I will call the psychological analogues of Kripke-style arguments provide a substantial motivation for a reference-based approach to concepts. Insofar as such an approach is rarely given serious consideration, the availability of these arguments suggests the need for a rethinking of some foundational assumptions in philosophy of mind and other branches of (...) the cognitive sciences.

The present article aims to show that a subject can only fully grasp the concept of the past if she has some experiential, or recollective, memories of particular past events. More specifically, I argue that (1) in order for a subject to understand the concept of the past, it is necessary that the subject understand the concept of a particular past event in such a way that it might contribute to her understanding of the concept of the past. (2) But (...) then, in order for a subject to understand the concept of a particular past event in such a way that it might contribute to her understanding of the concept of the past, it is necessary that the subject have some recollective memories of particular past events. (C) Hence, a subject can only understand the concept of the past if she has some recollective memories of particular past events. I defend the premises of the present argument against various objections, indicate why we should accept both premises, and accordingly end by endorsing the argument's conclusion. (shrink)

This paper defends a non-reductive realist view of the sensible qualities—roughly, the view that the sensible qualities are really instantiated by the external objects of perception, and not reducible to response-independent physical properties or response-dependent relational properties. I begin by clarifying and motivating the non-reductive realist view. I then consider some familiar difficulties for the view. Addressing these difficulties leads to the development and defence of a general theory, inspired by Russellian Monist theories of consciousness, of how the sensible qualities (...) relate to physical reality. I conclude by showing how this theory, which I call ‘Secondary Quality Russellian Monism’, resolves the most significant difficulties for the non-reductive realist view of the sensible qualities.

Many think that expressivists have a special problem with negation. I disagree. For if there is a problem with negation, I argue, it is a problem shared by those who accept some plausible claims about the nature of intentionality. Whether there is any special problem for expressivists turns, I will argue, on whether facts about what truth-conditions beliefs have can explain facts about basic inferential relations among those beliefs. And I will suggest that the answer to this last question is, (...) on most plausible attempts at solving the problem of intentionality, ‘no’. (shrink)

In this paper, I defend a well-known theory of belief reports from an important objection.

The objection concernssubstitution of co-referring names in belief sentences. Russellianism implies that any two belief sentences, that differ only in containing distinct co-referring names, express the same proposition (in any given context). Since `Hesperus' and `Phosphorus' both refer to the planet Venus, this view implies that (...) all utterances of (1) and.. (shrink)

What is creativity? One new idea may be creative, whereas another is merely new: What's the difference? And how is creativity possible? These questions about human creativity can be answered, at least in outline, using computational concepts. There are two broad types of creativity, improbabilist and impossibilist. Improbabilist creativity involves novel combinations of familiar ideas. A deeper type involves METCS: the mapping, exploration, and transformation of conceptual spaces. It is impossibilist, in that ideas may be generated which – with respect (...) to the particular conceptual space concerned – could not have been generated before. The more clearly conceptual spaces can be defined, the better we can identify creative ideas. Defining conceptual spaces is done by musicologists, literary critics, and historians of art and science. Humanist studies, rich in intuitive subtleties, can be complemented by the comparative rigour of a computational approach. Computational modelling can help to define a space, and to show how it may be mapped, explored, and transformed. Impossibilist creativity can be thought of in “classical” Al terms, whereas connectionism illuminates improbabilist creativity. Most Al models of creativity can only explore spaces, not transform them, because they have no self-reflexive maps enabling them to change their own rules. A few, however, can do so. A scientific understanding of creativity does not destroy our wonder at it, nor does it make creative ideas predictable. Demystification does not imply dehumanization. (shrink)

According to the Computational/Representational Theory of Thought (CRTT ? Language of Thought Hypothesis, or LOTH), propositional attitudes, such as belief, desire, and the like, are triadic relations among subjects, propositions, and internal mental representations. These representations form a representational _system_ physically realized in the brain of sufficiently sophisticated cognitive organisms. Further, this system of representations has a combinatorial syntax and semantics, but the processes that operate on the representations are causally sensitive only to their syntax, not to their semantics. On (...) this approach, a first pass account of propositional attitudes is the following (cf. Field 1978: 37 and Fodor 1987: 17). (shrink)

Fodor and Pylyshyn's critique of connectionism has posed a challenge to connectionists: Adequately explain such nomological regularities as systematicity and productivity without postulating a "language of thought" (LOT). Some connectionists like Smolensky took the challenge very seriously, and attempted to meet it by developing models that were supposed to be non-classical. At the core of these attempts lies the claim that connectionist models can provide a representational system with a combinatorial syntax and processes sensitive to syntactic structure. They are not (...) implementation models because, it is claimed, the way they obtain syntax and structure sensitivity is not "concatenative," hence "radically different" from the way classicists handle them. In this paper, I offer an analysis of what it is to physically satisfy/realize a formal system. In this context, I examine the minimal truth-conditions of LOT Hypothesis. From my analysis it will follow that concatenative realization of formal systems is irrelevant to LOTH since the very notion of LOT is indifferent to such an implementation level issue as concatenation. I will conclude that to the extent to which they can explain the law-like cognitive regularities, a certain class of connectionist models proposed as radical alternatives to the classical LOT paradigm will in fact turn out to be LOT models, even though new and potentially very exciting ones.

This essay is a sustained attempt to bring new light to some of the perennial problems in philosophy of mind surrounding phenomenal consciousness and introspection through developing an account of sensory and phenomenal concepts. Building on the information-theoretic framework of Dretske (1981), we present an informational psychosemantics as it applies to what we call sensory concepts, concepts that apply, roughly, to so-called secondary qualities of objects. We show that these concepts have a special informational character and semantic structure that closely (...) tie them to the brain states realizing conscious qualitative experiences. We then develop an account of introspection which exploits this special nature of sensory concepts. The result is a new class of concepts, which, following recent terminology, we call phenomenal concepts: these concepts refer to phenomenal experience itself and are the vehicles used in introspection. On our account, the connection between sensory and phenomenal concepts is very tight: it consists in different semantic uses of the same cognitive structures underlying the sensory concepts, such as the concept of red. Contrary to widespread opinion, we show that information theory contains all the resources to satisfy internalist intuitions about phenomenal consciousness, while not offending externalist ones. A consequence of this account is that it explains and predicts the so-called conceivability arguments against physicalism on the basis of the special nature of sensory and phenomenal concepts. Thus we not only show why physicalism is not threatened by such arguments, but also demonstrate its strength in virtue of its ability to predict and explain away such arguments in a principled way. However, we take the main contribution of this work to be what it provides in addition to a response to those conceivability arguments, namely, a substantive account of the interface between sensory and conceptual systems and the mechanisms of introspection as based on the special nature of the information flow between them.

The objective of this thesis is to present a naturalised metaphysics of information, or to naturalise information, by way of deploying a scientific metaphysics according to which contingency is privileged and a-priori conceptual analysis is excluded (or at least greatly diminished) in favour of contingent and defeasible metaphysics. The ontology of information is established according to the premises and mandate of the scientific metaphysics by inference to the best explanation, and in accordance with the idea that the primacy of physics (...) constraint accommodates defeasibility of theorising in physics. This metametaphysical approach is used to establish a field ontology as a basis for an informational structural realism. This is in turn, in combination with information theory and specifically mathematical and algorithmic theories of information, becomes the foundation of what will be called a source ontology, according to which the world is the totality of information sources. Information sources are to be understood as causally induced configurations of structure that are, or else reduce to and/or supervene upon, bounded (including distributed and non-contiguous) regions of the heterogeneous quantum field (all quantum fields combined) and fluctuating vacuum, all in accordance with the above-mentioned quantum field-ontic informational structural realism (FOSIR.) Arguments are presented for realism, physicalism, and reductionism about information on the basis of the stated contingent scientific metaphysics. In terms of philosophical argumentation, realism about information is argued for primarily by way of an indispensability argument that defers to the practice of scientists and regards concepts of information as just as indispensable in their theories as contingent representations of structure. Physicalism and reductionism about information are adduced by way of the identity thesis that identifies the substance of the structure of ontic structural realism as identical to selections of structure existing in re to combined heterogeneous quantum fields, and to the total heterogeneous quantum field comprised of all such fields. Adjunctly, an informational statement of physicalism is arrived at, and a theory of semantic information is proposed, according to which information is intrinsically semantic and alethically neutral.

This thesis aims to develop a psychologically plausible account of concepts by integrating key insights from philosophy (on the metaphysical basis for concept possession) and psychology (on the mechanisms underlying concept acquisition). I adopt an approach known as informational atomism, developed by Jerry Fodor. Informational atomism is the conjunction of two theses: (i) informational semantics, according to which conceptual content is constituted exhaustively by nomological mind–world relations; and (ii) conceptual atomism, according to which (lexical) concepts have no internal structure. I (...) argue that informational semantics needs to be supplemented by allowing content-constitutive rules of inference (“meaning postulates”). This is because the content of one important class of concepts, the logical terms, is not plausibly informational. And since, it is argued, no principled distinction can be drawn between logical concepts and the rest, the problem that this raises is a general one. An immediate difficulty is that Quine’s classic arguments against the analytic/synthetic distinction suggest that there can be no principled basis for distinguishing content-constitutive rules from the rest. I show that this concern can be overcome by taking a psychological approach: there is a fact of the matter as to whether or not a particular inference is governed by a mentally-represented inference rule, albeit one that analytic philosophy does not have the resources to determine. I then consider the implications of this approach for concept acquisition. One mechanism underlying concept acquisition is the development of perceptual detectors for the objects that we encounter. I investigate how this might work, by drawing on recent ideas in ethology on ‘learning instincts’, and recent insights into the neurological basis for perceptual learning. What emerges is a view of concept acquisition as involving a complex interplay between innate constraints and environmental input. This supports Fodor’s recent move away from radical concept nativism: concept acquisition requires innate mechanisms, but does not require that concepts themselves be innate. (shrink)

Jerry Fodor and Ernest Lepore (1999/2002) frame the debate over meaning holism in terms of a distinction between meaning atomism and meaning anatomism. The former holds that the meaning of an expression E is determined by some relation between E and some extra-linguistic entity. The latter holds that the meaning of E is at least partly determined by some of E’s “inward” relations (IRs) with other expressions in the very language. They (1992) argue that meaning anatomism inevitably collapses into meaning (...) holism, which is the view that the meaning of E is determined by E’s IRs with every other expression in the very language because there is no principled distinction for the anatomist to divide the meaning-determining IRs from the non-meaning-determining ones. In response, the non-holistic anatomist urges that Fodor and Lepore’s no-principled-basis consideration is groundless because the lack of a generally accepted criterion for such a distinction does not undermine the viability of the distinction itself. While this point is well taken, I think that Fodor and Lepore are onto an important question here. That is, what does it make non-holistic anatomism distinctive from its holistic counterpart if without a principled basis for the distinction among IRs? I look into this question and give an alternative argument from Fodor and Lepore’s to suggest that non-holistic anatomism cannot bypass the no-principled-basis consideration. The non-holistic anatomist will need a principled distinction in kind between IRs to back her point. (shrink)

The structuralist heritage in linguistics continues to obscure the essential properties of natural language as an empirical phenomenon. It is argued that the new framework of autopoiesis possesses a greater explanatory power, as it assumes the connotational na-ture of language. The key notions of representation, sign and signification, interpreta-tion, intentionality and communication, and reciprocal causality, approached from the autopoietic angle, allow for deeper insights into the essence of language which is as a kind of adaptive behavior of an organism involving (...) a system constituted by signs of signs.

This chapter probes the connections between the metaphysics of meaning and the investigation of human communication. It first argues that contemporary philosophy of mind has inherited most of its metaphysical questions from Brentano's puzzling definition of intentionality. Then it examines how intentionality came to occupy the forefront of pragmatics in three steps. By investigating speech acts, Austin and ordinary language philosophers pioneered the study of intentional actions performed by uttering sentences of natural languages. Based on his novel concept of speaker's (...) meaning and his inferential view of human communication as a cooperative and rational activity, Grice developed a three-tiered model of the meaning of utterances: the linguistic meaning of the uttered sentence; the explicit truth-conditional content of the utterance; the implicit content conveyed by the utterance. Finally, the new emerging truth-conditional trend in pragmatics urges that not only the implicit content conveyed by an utterance but its explicit content as well depends on the speaker's communicative intention.
