A traditional view maintains that thought, while expressed in language, is non-linguistic in nature and occurs in non-linguistic beings as well. I assess this view against current theories of the evolutionary design of human grammar. I argue that even if some forms of human thought are shared with non-human animals, a residue remains that characterizes a unique way in which human thought is organized as a system. I explore the hypothesis that the cause of this difference is a grammatical way (...) of structuring semantic information, and I present evidence that the organization of grammar precisely reflects the organization of a specific mode of thought apparently distinctive of humans. Since there appears to be no known non-grammatical structuring principle for the relevant mode of thought, I suggest that grammar is that principle, with no independent ?Language of Thought? needed.

In this book leading scholars from every relevant field report on all aspects of compositionality, the notion that the meaning of an expression can be derived from its parts. Understanding how compositionality works is a central element of syntactic and semantic analysis and a challenge for models of cognition. It is a key concept in linguistics and philosophy and in the cognitive sciences more generally, and is without question one of the most exciting fields in the study of language and (...) mind. The authors of this book report critically on lines of research in different disciplines, revealing the connections between them and highlighting current problems and opportunities. -/- The force and justification of compositionality have long been contentious. First proposed by Frege as the notion that the meaning of an expression is generally determined by the meaning and syntax of its components, it has since been deployed as a constraint on the relation between theories of syntax and semantics, as a means of analysis, and more recently as underlying the structures of representational systems, such as computer programs and neural architectures. The Oxford Handbook of Compositionality explores these and many other dimensions of this challenging field. It will appeal to researchers and advanced students in linguistics and philosophy and to everyone concerned with the study of language and cognition including those working in neuroscience, computational science, and bio-informatics.

This pioneering book lays new foundations for the study of reference and truth.

Contemporary arguments for forms of psycho-physical dualism standardly depart from phenomenal aspects of consciousness ('what it is like' to have some particular conscious experience). Conceptual aspects of conscious experience, as opposed to phenomenal or visual/perceptual ones, are often taken to be within the scope of functionalist, reductionist, or physicalist theories. I argue that the particular conceptual structure of human consciousness makes this asymmetry unmotivated. The argument for a form of dualism defended here proceeds from the empirical premise that (...) conceptual structure in a linguistic creature like us is a combinatorial and compositional system that implicates a distinction between simple and complex, or 'atomic' and 'molecular' concepts. The argument is that conceptual atoms, qua atoms, are irreducible to anything else. If so, and if the atoms are essentially semantic, a form of dualism follows: though positively inviting naturalistic inquiry into the semantic and mental aspects of nature, it requires that we look at the mental as a primitive domain of nature. Schematically, then, the argument is as follows: (1) Human consciousness/thought is conceptually structured. (2) The human conceptual system is a 'particulate' system at a syntactic and semantic level of representation (the notion of a 'particulate' system is developed in Section 2). (3) This implies the existence of conceptual 'particles', concepts that have no further semantic decomposition ('atoms'). (4) A conceptual atom cannot be explained in terms of anything that does not involve its own intrinsic properties (Section 3). (5) Physicalism as normally conceived is inconsistent with (3) and (4) (Section 4). (shrink)

Internalism is an explanatory strategy that makes the internal structure and constitution of the organism a basis for the investigation of its external function and the ways in which it is embedded in an environment. It is opposed to an externalist explanatory strategy, which takes its departure from observations about external function and mind-environment interactions, and infers and rationalizes internal organismic structure from that. This paper addresses the origins of truth, a basic ingredient in the human conceptual scheme. I suggest (...) the necessity of pursuing an internalist line of explanation for it, as adopted in the biolinguistic program and generative grammar at large. According to this view, the concept of truth is a presupposition for the way language is used in relation to the world, rather than a function of that use or a consequence of language-world relations.

Mind–body dualism has rarely been an issue in the generative study of mind; Chomsky himself has long claimed it to be incoherent and unformulable. We first present and defend this negative argument but then suggest that the generative enterprise may license a rather novel and internalist view of the mind and its place in nature, different from all of, (i) the commonly assumed functionalist metaphysics of generative linguistics, (ii) physicalism, and (iii) Chomsky’s negative stance. Our argument departs from the empirical (...) observation that the linguistic mind gives rise to hierarchies of semantic complexity that we argue (only) follow from constraints of an essentially mathematical kind. We assume that the faculty of language tightly correlates with the mathematical capacity both formally and in evolution, the latter plausibly arising as an abstraction from the former, as a kind of specialized output. On this basis, and since the semantic hierarchies in question are mirrored in the syntactic complexity of the expression involved, we posit the existence of a higher-dimensional syntax structured on the model of the hierarchy of numbers, in order to explain the semantic facts in question. If so, syntax does not have a physicalist interpretation any more than the hierarchy of number-theoretic spaces does. (shrink)

In a recent paper, Kit Fine offers a reconstruction of Cantor's theory of ordinals. It avoids certain mentalistic overtones in it through both a non-standard ontology and a non-standard notion of abstraction. I argue that this reconstruction misses an essential constructive and computational content of Cantor's theory, which I in turn reconstruct using Martin-Löf's theory of types. Throughout, I emphasize Kantian themes in Cantor's epistemology, and I also argue, as against Michael Hallett's interpretation, for the need for a constructive understanding (...) of Cantorian ?existence principles?

Carnap took the content of a particular sentence or set of sentences to consist in the set ofthe consequences of the sentence or set. This claim equates meaning with inferential role, but it restricts the inferences to deductive or explicative ones. Here I reject a recent proposal by Rober Brandom, where inductive or ampliative inferences arealso meant to confer contents on expressions. I argue that if Brandom's inferentialist picture is upheld, and both explicative and ampliative inferences confer meaning, one consequence (...) of this is that the content of a sentence is to be read off from our ways of rationally altering our beliefs. Meaning and content then are largely concepts of pragmatics, with no clear theoretical interest. My critique affects certain aspects of Dummett's meaning-theoretic picture too,and the discussion also links up with the development of `dynamic semantics'. (shrink)

I argue that the implementation of theDummettian program of an ``anti-realist'' semanticsrequires quite different conceptions of the technicalmeaning-theoretic terms used than those presupposed byDummett. Starting from obvious incoherences in anattempt to conceive truth conditions as assertibilityconditions, I argue that for anti-realist purposesnon-epistemic semantic notions are more usefully kept apart from epistemic ones rather than beingreduced to them. Embedding an anti-realist theory ofmeaning in Martin-Löf's Intuitionistic Type Theory(ITT) takes care, however, of many notorious problemsthat have arisen in trying to specify suitableintuitionistic (...) notions of semantic value,truth-conditions, and validity, taking into accountthe so-called ``defeasibility of evidence'' forassertions in empirical discourses.
