The Realist that investigates questions of ontology by appeal to the quantificational structure of language assumes that the semantics for the privileged language of ontology is externalist. I argue that such a language cannot be (some variant of) a natural language, as some Realists propose. The flexibility exhibited by natural language expressions noted by Chomsky and others cannot obviously be characterized by the rigid models available to the externalist. If natural languages are hostile to externalist treatments, then the meanings of (...) natural language expressions serve as poor guides for ontological investigation, insofar as their meanings will fail to determine the referents of their constituents. This undermines the Realist’s use of natural languages to settle disputes in metaphysics. (shrink)

This paper explores how words relate to concepts. It argues that in many cases, words get their meanings in part by associating with concepts, but only in conjunction with substantial input from language. Language packages concepts in grammatically determined ways. This structures the meanings of words, and determines which sorts of concepts map to words. The results are linguistically modulated meanings, and the extralinguistic concepts associated with words are often not what intuitively would be expected. The paper concludes by discussing (...) implications of this thesis for the relation of word to sentence meaning, and for issues of linguistic determinism. (shrink)

This paper considers a form of scepticism according to which sentences, along with other linguistic entities such as verbs and phonemes, etc., are never realized. If, whenever a conversational participant produces some noise or other, they and all other participants assume that a specific sentence has been realized (or, more colloquially, spoken), communication will be fluent whether or not the shared assumption is correct. That communication takes place is therefore, one might think, no ground for assuming that sentences are realized (...) during a typical conversation. I reject both this ‘folie-a-deux’ view and the arguments for it due to Georges Rey. I do so by drawing on Gilbert Harrnan’s no-false-lemmas principle. Since testimony is a form of knowledge and, according to the principle, knowledge cannot depend essentially on false assumptions, testimony is incompatible with the claim that sentence realization is but an illusion. Much of the paper is given over to defending this appeal to the no-false-lemmas principle. After all, a more attractive option might seem to be to infer instead that the principle is itself falsified by the folie-a-deux view. (shrink)

cal practice: the enterprise of specifying information about the world for use in computer systems. Knowledge representation as a field also encompasses conceptual results that call practitioners’ attention to important truths about the world, mathematical results that allow practitioners to make these truths precise, and computational results that put these truths to work. This chapter surveys this practice and its results, as it applies to the interpretation of natural language utterances in implemented natural language processing systems. For a broader perspective (...) on such technical practice, in all its strengths and weaknesses, see (Agre 1997). Knowledge representation offers a powerful general tool for the science of language. Computational logic, a prototypical formalism for representing knowledge about the world, is also the model for the level of logical form that linguists use to characterize the grammar of meaning (Larson and Segal 1995). And researchers from (Schank and Abelson 1977) to (Shieber 1993) and (Bos to appear) have relied crucially on such representations, and the inference methods associated with them, in articulating accounts of semantic relations in language, such as synonymy, entailment, informativeness and contradiction. The new textbooks (Blackburn and Bos 2002a, Blackburn and Bos 2002b) provide an excellent grounding in this research, and demonstrate how deeply computational ideas from knowledge representation can inform pure linguistic study. In this short chapter, I must leave much of.. (shrink)

Does scientific psychology have a legitimate role to play in the philosophy of language? For example, is it methodologically permissible for philosophers of language to rely upon evidence from neurological development, experiments about processing, brain scans, clinical case histories, longitudinal studies, questionnaires, etc.? If so, why? These two questions are the focus of this survey. I address them in two stages. It may seem obvious that the science of psychology is relevant. I thus begin by introducing arguments against relevance, to (...) motivate the discussion. I will urge that these arguments ultimately fail, and that the appearance of relevance should be taken at face value. Next, I introduce positive arguments for relevance, with examples. To foreshadow the main conclusion, the methods and results of contemporary cognitive psychology are relevant because there are non-obvious connections, both constitutive and contingent, between language and human psychology.

The first hurdle to overcome in approaching the complex topic of the relation between language and consciousness is terminology. So let me begin, in good philosophical style, by explaining the senses in which I use the three lexical terms in the title. Luckily I need not explain those of the three grammatical words the, of, and on: there is probably a minor library of semantic literature devoted to that. I need not, since I both know their meanings pre-theoretically, and know (...) that my readers, as users of English, know them. The significance of this simple fact concerning the meaning of all everyday words, in everyday constructs, is something that I will return to, since it plays a central role in the argument in Section 2. However, with abstract, theoretically loaded nominalizations such as dependence, language, and most of all consciousness, we need to beware since we cannot assume common knowledge -- myriads of misunderstandings arise since we mean somewhat different 'things' by them. I start with the easiest, by which I mean specifically ' dependence of language on consciousness', explaining only afterward what I mean by the latter terms. I ask the reader to bear this circularity with me. (shrink)

The aim of this paper is to reconsider certain assumptions about conceptual structure which have become influential in recent Cognitive Science and which are associated in particular with the Cognitive Linguistics research agenda. I will outline three areas within the Cognitive Linguistics theory of concepts which seem to create some difficulties in their present formulation: the 'embodied cognition' idea, the function of imagery and the role of metaphor in the structure of concepts.

We show how an epistemology informed by cognitive science promises to shed light on an ancient problem in the philosophy of mathematics: the problem of exactness. The problem of exactness arises because geometrical knowledge is thought to concern perfect geometrical forms, whereas the embodiment of such forms in the natural world may be imperfect. There thus arises an apparent mismatch between mathematical concepts and physical reality. We propose that the problem can be solved by emphasizing the ways in which the (...) brain can transform and organize its perceptual intake. It is not necessary for a geometrical form to be perfectly instantiated in order for perception of such a form to be the basis of a geometrical concept. (shrink)

Given the fundamental role that concepts play in theories of cognition, philosophers and cognitive scientists have a common interest in concepts. Nonetheless, there is a great deal of controversy regarding what kinds of things concepts are, how they are structured, and how they are acquired. This chapter offers a detailed high-level overview and critical evaluation of the main theories of concepts and their motivations. Taking into account the various challenges that each theory faces, the chapter also presents a novel approach (...) to concepts that is organized around two ideas. The first is a pluralistic view of differing types of conceptual structure. The second is a model that treats concepts as atomic representations that are linked to various types of conceptual structures. (shrink)

The development of possible worlds semantics for modal claims has led to a more general application of that theory as a complete semantics for various formal and natural languages, and this view is widely held to be an adequate (philosophical) interpretation of the model theory for such languages. We argue here that this view generates a self-referential inconsistency that indicates either the falsity or the incompleteness of PWS.

Suppose that one adopts a broadly Chomskyan perspective, in which there is a distinction between the language faculty and other cognitive faculties, including what Chomsky has recently called the “Conceptual-Intensional system”. Then there must in principle be at least three stages in this association that need to be understood. First, there is the nonlinguistic stage of conceptualizing a particular event.1 For example, while all of the participants in an event may be affected by the event in some way or another, (...) human cognizers typically focus on one or the other of those changes as being particularly salient or relevant to their interests. This participant is taken to be the “theme” or “patient” of the event, perhaps in some kind of nonlinguistic conceptual representation, such as the one developed by Jackendoff (1983, 1990b). Second, this conceptual/thematic representation is associated with a linguistic representation in which the entity seen as the patient of the event is represented as (say) an NP that is the direct object of the verb that expresses what kind of an event it was. This is the interface between language and the conceptual system. Finally, there is the possibility of adjusting this representation internally to the language system, by way of movements, chain formations, Case assignment processes, or whatever other purely syntactic processes there may be. For example, the NP that represents the theme and starts out as the direct object of the verb may become the subject if there is no other subject in the linguistic representation, either because there was no agent in the conceptual representation (as with an unaccusative verb), or because it was suppressed (as with a passive verb).

The transition from Middle English to Modern English in the second half of the 14th century is a turning point in the syntax of the language. It is at once the point when several constraints on nominal arguments that had been gaining ground since Old English become categorical, and the point when a reorganization of the functional category Infl is initiated, whose completion over the next several centuries yields essentially the syntactic system of the present day. From this time on, (...) subjects are obligatory, and they must be placed in Spec-IP position. In the VP, the last traces of OV order disappear, the order of direct and indirect object becomes fixed, the first “recipient passives” enter the language, and objects cease to be separable from the verb by adverbs or adjuncts. The V2 constraint of Old and Middle English is lost, as topicalized constituents cease to trigger verb-fronting. Concurrently, in the Infl system, the first instances of periphrastic do-support begin to replace fronting of the finite main verb, and, with the appearance of split infinitives and pro-infinitives, to starts to pattern as a non-finite Aux rather than, as in earlier stages, as a prefix marking the infinitive. All these changes have been dated to the second half of the 14th century, most of them specifically to the period between 1360 and 1380. (shrink)

Word meaning confronts us, as acutely as anything in syntax, with what Chomsky has called Plato’s problem.1 We know far more about the meaning of almost any word than we could have learned just from our exposure to uses of it. Communication would be unbearably laborious if we did not share with other speakers the ability to generalize the meanings of words in the right ways. As Fodor (1981) notes in arguing for the innateness of lexical semantics, the most we (...) might plausibly have learned about meaning of the verb paint is that it means something like “to cover with paint”. Even if we have only seen this done with a brush, we have no hesitation in applying the verb correctly to novel techniques of painting, such as rolling, spraying, or dipping. But when a vat of paint explodes in a paint factory, covering everyone with paint, or when Vel´. (shrink)

Robyn Carston and I share a general methodological position which I call ‘Truth-Conditional Pragmatics' (TCP). TCP is the view that the effects of context on truth-conditional content need not be traceable to the linguistic material in the uttered sentence. Some effects of context on truth-conditional content are due to the linguistic material (e.g. to context-sensitive words or morphemes which trigger the search for contextual values), but others result from ‘free' pragmatic processes. Free pragmatic processes take place not because the linguistic (...) material demands it, but because the utterance's content is not faithfully or wholly encoded in the uttered sentence, whose meaning requires adjustment or elaboration in order to determine an admissible content for the speaker's utterance. To make room for these processes, I will argue, we need to distinguish the logical form of an utterance, in the standard sense, and its modified logical form, affected by free pragmatic processes. This distinction will be elaborated and I will show that it can be interpreted in three different ways. (shrink)

Jackendoff (1987, 1990) has brought up various problems with the current use of thematic roles (Kiparsky, 1987; Bresnan & Kanerva, 1989 and references cited therein) and suggested a different way of thinking of thematic roles as structural configurations in his semantic Lexical Conceptual Structures (LCSs). Conversely, Joshi (1989) has claimed that Jackendoff’s LCSs alone are insufficient, and that an analysis of certain facts in Marathi additionally requires the existence of a level of predicate-argument structure (PAS). Below we will mention a (...) few of Jackendoff’s arguments against the current conception of thematic roles. We will then look at Joshi’s arguments about the necessity of a level of PAS in addition to LCS and conclude that providing Jackendoff’s LCSs are integrated into a suitable syntactic theory, neither of her points are problematic to Jackendoff.1 From there we will go on to re-examine some of the facts of Marathi, and show that certain facts that have merely been stipulated or left unanalyzed when using thematic roles, receive a rather elegant treatment when described via a combination of their syntax and LCS.
