Je soutiens qu’accepter les explications réalistes intentionnelles du comportement cognitif conduit inévitablement à endosser l’hypothèse du langage de la pensée, et que cette position théorique est, par conséquent, largement répandue chez les philosophes de l’esprit. Au cours de la discussion, je propose un exposé succinct et précis de cette hypothèse et j’analyse une série d’exemples représentatifs de l’argumentation pro-LOT. Après avoir examiné deux cas de résistance à ce type de raisonnement, je conclus en montrant que le soutien accordé à la (...) LOT est empiriquement substantiel, en dépit de la flexibilité et du caractère incomplet de cette hypothèse. (shrink)

Marr’s celebrated contribution to cognitive science (Marr 1982, chap. 1) was the introduction of (at least) three levels of description/explanation. However, most contemporary research has relegated the distinction between levels to a rather dispensable remark. Ignoring such an important contribution comes at a price, or so we shall argue. In the present paper, first we review Marr’s main points and motivations regarding levels of explanation. Second, we examine two cases in which the distinction between levels has been neglected when considering (...) the structure of mental representations: Cummins et al.’s distinction between structural representation and encodings (Cummins in Journal of Philosophy, 93(12):591–614, 1996; Cummins et al. in Journal of Philosophical Research, 30:405–408, 2001) and Fodor’s account of iconic representation (Fodor 2008). These two cases illustrate the kind of problems in which researchers can find themselves if they overlook distinctions between levels and how easily these problems can be solved when levels are carefully examined. The analysis of these cases allows us to conclude that researchers in the cognitive sciences are well advised to avoid risks of confusion by respecting Marr’s old lesson. (shrink)

Epistemology of language, a branch of both epistemology and the philosophy of language, asks what knowledge of language consists in. In this paper, I argue that such an inquiry is a pointless enterprise due to its being based upon the incorrect assumption that linguistic competence requires knowledge of language. However, I do not think the phenomenon of knowledge of language is trivial. I propose a virtue-theoretic account of linguistic competence, and then explain the phenomenon from a virtue-semantic point of view.

Knowledge of a language is a kind of knowledge, the possession of which enables a speaker to understand and perform a variety of linguistic actions in that language. In this paper, I pursue an agency-oriented approach to knowledge of language. I begin by examining two major agency-oriented models of knowledge of language: Michael Dummett's Implicit Knowledge Model and Jennifer Hornsby's Practical Knowledge Model. I argue that each of these models is inadequate for different reasons. I present an Acquaintance Knowledge Model, (...) in which a speaker's knowledge of a language is a combination of the speaker's first-order linguistic ability and second-order acquaintance with his ability and actions.

The semantic automata framework, developed originally in the 1980s, provides computational interpretations of generalized quantifiers. While recent experimental results have associated structural features of these automata with neuroanatomical demands in processing sentences with quantifiers, the theoretical framework has remained largely unexplored. In this paper, after presenting some classic results on semantic automata in a modern style, we present the first application of semantic automata to polyadic quantification, exhibiting automata for iterated quantifiers. We also discuss the role of semantic automata in (...) linguistic theory and offer new empirical predictions for sentence processing with embedded quantifiers. (shrink)

Abstract In the first part of this essay (Russell, 1988a) I argued that ?cognisance? (roughly: a subject's knowledge of his relation to the physical world as an experiencer of it) cannot be explained in terms of a syntactic theory of mind, due to the ?referential? and ?holistic? nature of this knowledge. The syntactic account of the higher mental functions is immediately intelligible to us due to its derivation from computer technology, so this would not appear to be a happy result (...) for scientific psychology. In this paper I outline a strategy for developing a scientific psychology of cognisance, beginning from the assumption that such a theory should have a similar status to Chomsky's competence theory of human grammar, whilst diverging from Chomsky on the question of how such a theory should be answerable to data. Most of the paper is taken up with illustrating the way in which Jean Piaget's theory of mental development in humans is at least a first approximation to such a theory. (shrink)

I defend the non-cognitivist outlook on knowledge of grammar from the criticisms levelled against it by Jonathan Knowles. The first part of the paper is largely critical. First, I argue that Knowles's argument against Christopher Peacocke and Martin Davies's non-cognitivist account of the psychological reality of grammar fails, and thus that no reason has been given to think that cognitivism is integral to an understanding of Chomskyan theoretical linguistics. Second, I argue that cognitivism is philosophically problematic. In particular, I argue (...) (a) that Knowles misunderstands Stephen Stich and Gareth Evans's points about inferential integration; and (b) that Knowles misunderstands the philosophical status and demands of Evans's Generality Constraint. In the final, non-critical part of the paper, I try to show that the Stich and Evans's constraints, together with a Self-Knowledge Constraint, are genuine constitutive constraints by showing how they have rationality as their underlying organizing principle. I argue further that recognizing the constitutive character of these constraints allows one to distinguish two kinds of psychological explanation; in this sense, the constraints mark a genuine boundary in our theorizing about the mind.

The meaning of 'most' can be described in many ways. We offer a framework for distinguishing semantic descriptions, interpreted as psychological hypotheses that go beyond claims about sentential truth conditions, and an experiment that tells against an attractive idea: 'most' is understood in terms of one-to-one correspondence. Adults evaluated 'Most of the dots are yellow', as true or false, on many trials in which yellow dots and blue dots were displayed for 200 ms. Displays manipulated the ease of using a (...) 'one-to-one with remainder' strategy, and a strategy of using the Approximate Number System to compare of (approximations of) cardinalities. Interpreting such data requires care in thinking about how meaning is related to verification. But the results suggest that 'most' is understood in terms of cardinality comparison, even when counting is impossible. (shrink)

This paper proposes an Interface Transparency Thesis concerning how linguistic meanings are related to the cognitive systems that are used to evaluate sentences for truth/falsity: a declarative sentence S is semantically associated with a canonical procedure for determining whether S is true; while this procedure need not be used as a verification strategy, competent speakers are biased towards strategies that directly reflect canonical specifications of truth conditions. Evidence in favor of this hypothesis comes from a psycholinguistic experiment examining adult judgments (...) concerning ‘Most of the dots are blue’. This sentence is true if and only if the number of blue dots exceeds the number of nonblue dots. But this leaves unsettled, e.g., how the second cardinality is specified for purposes of understanding and/or verification: via the nonblue things, given a restriction to the dots, as in ‘|{x: Dot(x) & ~Blue(x)}|’; via the blue things, given the same restriction, and subtraction from the number of dots, as in ‘|{x: Dot(x)}| – |{x: Dot(x) & Blue(x)}|’; or in some other way. Psycholinguistic evidence and psychophysical modeling support the second hypothesis. (shrink)

Noam Chomsky claims that we know the grammatical principles of our languages in pretty much the same sense that we know ordinary things about the world (e.g. facts), a view about linguistic knowledge that I term ''cognitivism''. In much recent philosophy of linguistics (including that sympathetic to Chomsky's general approach to language), cognitivism has been rejected in favour of an account of grammatical competence as some or other form of mental mechanism, describable at various levels of abstraction (''non-cognitivism''). I argue (...) for cognitivism and against non-cognitivism. First, I show that the distinction between competence and performance in current linguistics is as clearly made as ever it was, in spite of recent interest in linguistic processing modules. Second, I use these facts about the practice of theoretical linguistics to refute various proposals for a non-cognitivist construal of grammatical competence, and to support cognitivism by reflecting on the inapplicability of a multi-level account of linguistic competence. Cognitivism is then defended against several objections centring around the problems of rational integration and conceptualization of grammatical knowledge. Finally, the conception of competence argued for in relation to linguistics is placed in the larger context of cognitive science research and its implications for philosophy of mind. (shrink)

Critical notice of Andy Clark's "Associative Engines".

In this paper we consider two key concepts from software engineering—‘specification’ and ‘implementation’—and explore their possible applications outside software engineering to other disciplines, notably the philosophy of action, evolutionary biology, and cognitive science. Throughout, the emphasis is on the gain in conceptual clarity that can be afforded by these concepts; it is not so much a matter of new knowledge or new theories but of a reorganization of existing knowledge and theories in a way that facilitates the transfer of insights (...) across a range of related fields.

This article presents a detailed formal approach to concepts and concept combination. Sense generation is a competence‐level theory that attempts to respect constraints from the various cognitive sciences, and postulates “quasi‐classical” conceptual structures where attributes receive only one value (but are defeasible and so do not represent necessary and sufficient conditions on category membership) and where classification is binary (but explicitly context‐sensitive). It is also argued that any general theory of concepts must account for “privative” combinations (e.g., stone lion, fake (...) gun, apparent friend) as extreme test‐cases of representational and classificatory flexibility. The approach presented therefore provides a treatment of these combinations. The approach differentiates between the “lexical concept” (the stable information represented in a mental lexicon) which acts as a base from which the various “senses” (flexible contents associated with words and phrases in context, and used in classification) are “generated.” Generation allows nonmonotonicity, so that in different circumstances, different attributes may be defeated or modified. Classification is treated as relative to the perspective adopted, so that a classification acceptable from one perspective may be unacceptable from another, without contradiction. The result is a view that assumes bottom‐up priority in concept combination, where the range of senses generated by bottom‐up rules of combination is tempered by pragmatic‐communicative constraints on classification. An account of the representational and classification behavior of privative combinations is outlined, and the article concludes with a discussion of some of the implications of the approach.

The later Wittgenstein advanced a revolutionary but puzzling conception of how philosophy ought to be practised: Philosophical problems are not to be coped with by establishing substantive claims or devising explanations or theories. Instead, philosophical questions ought to be treated ‘like an illness’. Even though this ‘non-cognitivism’ about philosophy has become a focus of debate, the specifically ‘therapeutic’ aims and ‘non-theoretical’ methods constitutive of it remain ill understood. They are motivated by Wittgenstein’s view that the problems he addresses result from (...) misinterpretation, driven by ‘urges to misunderstand’. The present paper clarifies this neglected concept and analyses how such ‘urges’ give rise to pseudo-problems of one particular, hitherto little understood, kind. This will reveal ‘therapeutic’ aims reasonable and ‘non-theoretical’ methods necessary, in one clearly delineated and important part of philosophy. I.e.: By developing a novel account of nature and genesis of one important class of philosophical problems, the paper explains and vindicates a revolutionary reorientation of philosophical work, at the level of both aims and methods.

The paper develops a novel account of the nature and genesis of some philosophical problems, which motivates an unfamiliar form of philosophical criticism that was pioneered by the later Wittgenstein. To develop the account, the paper analyses two thematically linked sets of problems, namely problems about linguistic understanding: a set of problems Wittgenstein discusses in a core part of his Philosophical Investigations, and the ‘problem of linguistic creativity’ that is central to current philosophy of language. The paper argues that these (...) problems are generated by tacit and unwarranted presuppositions at odds with warranted beliefs the philosophers raising the problems reflectively hold at the same time. For a rigorous conceptualisation of this phenomenon, the paper develops the notion of a ‘philosophical picture’ first proposed by Wittgenstein, and specifies the particular class of philosophical problems that may be raised due to adherence to such pictures. The results motivate a new form of philosophical criticism: the systematic exposure of relevant philosophical pictures, and efforts to overcome their tacit influence on philosophical reflection.

The aim of the present paper is to understand what the notions of explanation and prediction in contemporary linguistics mean, and to compare various aspects that the notion of explanation encompasses in that domain. The paper is structured around an opposition between three main styles of explanation in linguistics, which I propose to call ‘grammatical’, ‘functional’, and ‘historical’. Most of this paper is a comparison between these different styles of explanations and their relations. A second, more methodological aspect this paper (...) seeks to clarify concerns the extent to which linguistic explanations can be viewed as predictive, rather than merely descriptive, and the problem of whether linguistic explanations ought to be causal, rather than noncausal. I argue that the notion of prediction is equally applicable in linguistics as in other empirical sciences. The extent to which the computational model of generative syntax can be viewed as providing a causal or psychologically realist model of language is more controversial. (shrink)

I defend a conception of the relationship between the personal and sub-personal levels as interaction withoutreduction.There are downward inferences from the personal to the sub-personal level but we find upward explanatory gaps when we try to construct illuminating accounts of personal level conditions using just sub-personal level notions. This conception faces several serious challenges but the objection that I consider in this paper says that, when theories support downward inferences from the personal to the sub-personal level, this is the product (...) of an unacceptably • mechanistic view of persons. According to this objection, if we were to focus on persons as conscious rational thinkers and agents then the support for putative downward inferences would be undermined. I consider and reject developments of this objection in response to two arguments for downward inferences. (shrink)

According to the most popular non-skeptical views about intuition, intuitions justify beliefs because they are based on understanding. More precisely: if intuiting that p justifies you in believing that p it does so because your intuition is based on your understanding of the proposition that p. The aim of this paper is to raise some challenges for accounts of intuitive justification along these lines. I pursue this project from a non-skeptical perspective. I argue that there are cases in which intuiting (...) that p justifies you in believing that p, but such that there is no compelling reason to think this is because your intuition is based on your understanding of the proposition that p.

Testimony, the transmission of knowledge through communication, requires a shared understanding of linguistic expressions and utterances of them. Is this understanding itself a kind of knowledge, knowledge of meaning? The intuitive answer is ‘yes’, but the nature of such knowledge is controversial, as is the assumption that understanding is a kind of knowledge at all. This article is a critical examination of recent work on the nature and role of semantic knowledge in the generation of the linguistic understanding needed for (...) testimony. After describing a default view – that linguistic understanding partially consists in the possession and application of knowledge of a compositional theory of truth conditions – it scrutinizes two recent charges against this view: that linguistic understanding and knowledge of meaning are conceptually distinct, and that semantic ‘knowledge’ is knowledge without an object.

This article deals with the cognitive relationship between a speaker and her internal grammar. In particular, it takes issue with the view that such a relationship is one of belief or knowledge (I call this view the ‘Propositional Attitude View’, or PAV). I first argue that PAV entails that all ordinary speakers (tacitly) possess technical concepts belonging to syntactic theory, and second, that most ordinary speakers do not in fact possess such concepts. Thus, it is concluded that speakers do not (...) literally ‘know’ or ‘believe’ much of the contents of their grammars, and moreover, that these contents can only be attributed at a subpersonal level.

Chomsky’s (1995, 2000a) Minimalist Program (MP) invites a perspective on semantics that is distinctive and attractive. In section one, I discuss a general idea that many theorists should find congenial: the spoken or signed languages that human children naturally acquire and use— henceforth, human languages—are biologically implemented procedures that generate expressions, whose meanings are recursively combinable instructions to build concepts that reflect a minimal interface between the Human Faculty of Language (HFL) and other cognitive systems. In sections two and three, (...) I develop this picture in the spirit of MP, in part by asking how much of the standard Frege-Tarski apparatus is needed in order to provide adequate and illuminating descriptions of the “concept assembly instructions” that human languages can generate. I’ll suggest that we can make do with relatively little, by treating all phrasal meanings as instructions to assemble number-neutral concepts that are monadic and conjunctive. But the goal is not to legislate what counts as minimal in semantics. Rather, by pursuing one line of Minimalist thought, I hope to show how such thinking can be fruitful. (shrink)
