We consider the logical form of a natural language sentence to be a formal object which determines both the logical properties of the sentence and, more generally, the ways the sentence is logically related to other sentences. Thus if some NL sentence logically entails another, this fact must follow, given the logical forms of the two sentences. The power of a theory of logical forms of natural language then lies first in what logical properties and relations it can define, and (...) second, in which NL sentences it can show to be logically related to which others.

In this volume, Geurts takes discourse representation theory (DRT), and turns it into a unified account of anaphora and presupposition, which he applies not only to the standard problem cases but also to the interpretation of modal expressions, attitude reports, and proper names. The resulting theory, for all its simplicity, is without doubt the most comprehensive of its kind to date. The central idea underlying Geurts' 'binding theory' of presupposition is that anaphora is just a special case of presupposition projection. (...) But this is only one of the ways in which the concept of presupposition is taken beyond its traditional limits. Geurts shows, furthermore, that presupposition projection is crucially involved in several phenomena that are not usually viewed in presuppositional terms, such as modal subordination, de re readings of attitude reports, and rigid designation. While making his case for DRT and the binding theory, Geurts also presents an incisive analysis of what is probably still the most influential account of presupposition, viz. the satisfaction theory, demonstrating that there are fundamental problems not only with this theory but with the very framework in which it is couched.

This anthology of essays on the work of David Kaplan, a leading contemporary philosopher of language, sprang from a conference, "Themes from Kaplan," organized by the Center for the Study of Language and Information at Stanford University.

In The Dynamics of Meaning , Gennaro Chierchia tackles central issues in dynamic semantics and extends the general framework. Chapter 1 introduces the notion of dynamic semantics and discusses in detail the phenomena that have been used to motivate it, such as "donkey" sentences and adverbs of quantification. The second chapter explores in greater depth the interpretation of indefinites and issues related to presuppositions of uniqueness and the "E-type strategy." In Chapter 3, Chierchia extends the dynamic approach to the domain (...) of syntactic theory, considering a range of empirical problems that includes backwards anaphora, reconstruction effects, and weak crossover. The final chapter develops the formal system of dynamic semantics to deal with central issues of definites and presupposition. Chierchia shows that an approach based on a principled enrichment of the mechanisms dealing with meaning is to be preferred on empirical grounds over approaches that depend on an enrichment of the syntactic apparatus. Dynamics of Meaning illustrates how seemingly abstract stances on the nature of meaning can have significant and far-reaching linguistic consequences, leading to the detection of new facts and influencing our understanding of the syntax/semantics/pragmatics interface.

This paper offers a critical analysis of Stalnaker''s work on presupposition (Stalnaker1973, 1974, 1979, 1999, 2002). The paper examines two definitions of speaker presupposition offered by Stalnaker – the familiar common ground view, and the earlier,less familiar, dispositional account – and how Stalnaker relates this notion to the linguistic phenomenon of presupposition. Special attention is paid to Stalnaker's view of accommodation. I argue that given Stalnaker's views, accommodation is not rightly seen as driven by the presuppositional requirements of utterances, but (...) only by the interests of speakers in eliminating perceived differences among presuppositions. I also consider the revisions which are needed either to the definition of speaker presupposition or to the definition of sentence presupposition in light of the possibility of informative presupposition. In the concluding section, I discuss the ways in which some recent accounts of context and speaker presupposition depart from their Stalnakerian foundations. (shrink)

As Grice defined it, a speaker conversationally implicates that p only if the speaker expects the hearer to recognize that the speaker thinks that p. This paper argues that in the sorts of cases that Grice took as paradigmatic examples of conversational implicature there is in fact no need for the hearer to consider what the speaker might thus have in mind. Instead, the hearer might simply make an inference from what the speaker literally says and the situation in which (...) the utterance takes place. In addition, a number of sources of the illusion of conversational implicatures in Grice's sense are identified and diagnosed. (shrink)

Russell and Strawson sparked a well known debate on the subject of Linguistic Presupposition inspiring many linguists and philosophers to follow suit, including Frege, whose work initiated the modern study in this area. Beaver begins with the most comprehensive overview and critical discussion of this burgeoning field published to date. He then goes on to motivate and develop his own account based on a Dynamic Semantics. This account is a recent line of theoretical work in which the Tarskian emphasis on (...) truth conditions is questioned. The central plank of the theory of meaning is a formal account of the change in information effected by use of language on hearers or readers. The proposal thus consolidates ideas of Stalnaker, Karttunen and Heim, all of whom had suggested that such an account was needed. At the same time it provides a new impulse and motivation to Dynamic Semantics itself. (shrink)

In Context and Content Robert Stalnaker develops a philosophical picture of the nature of speech and thought and the relations between them. Two themes in particular run through these collected essays: the role that the context in which speech takes place plays in accounting for the way language is used to express thought, and the role of the external environment in determining the contents of our thoughts. Stalnaker argues against the widespread assumption of the priority of linguistic over mental representation, (...) which he suggests has had a distorting influence on our understanding. The first part of the book develops a framework for representing contexts and the way they interact with the interpretation of what is said in them. This framework is used to help to explain a range of linguistic phenomena concerning presupposition and assertion, conditional statements, the attribution of beliefs, and the use of names, descriptions, and pronouns to refer. Stalnaker then draws out the conception of thought and its content that is implicit in this framework. He defends externalism about thought--the assumption that our thoughts have the contents they have in virtue of the way we are situated in the world--and explores the role of linguistic action and linguistic structure in determining the contents of our thoughts. Context and Content offers philosophers and cognitive scientists a summation of Stalnaker's important and influential work in this area. His new introduction to the volume gives an overview of this work and offers a convenient way in for those who are new to it. The Oxford Cognitive Science series is a new forum for the best contemporary work in this flourishing field, where various disciplines--cognitive psychology, philosophy, linguistics, cognitive neuroscience, and computational theory--join forces in the investigation of thought, awareness, understanding, and associated workings of the mind. Each book constitutes an original contribution to its subject, but will be accessible beyond the ranks of specialists, so as to reach a broad interdisciplinary readership. The series will be carefully shaped and steered with the aim of representing the most important developments in the field and bringing together its constituent disciplines. (shrink)

"If you turn left at the next corner, you will see a blue house at the end of the street." That sentence -- a conditional -- might be true even though it is possible that you will not see a blue house at the end of the street when you turn left at the next corner. A moving van may block your view; the house may have been painted pink; a crow might swoop down and peck out your eyes. Still, (...) in some contexts, we might ignore these possibilities and correctly assert the conditional. In this book, Christopher Gauker argues that such context-relativity is the key to understanding the semantics of conditionals. Contexts are defined as objective features of the situation in which a conversation takes place, and the semantic properties of sentences -- conditionals included -- are defined in terms of assertibility in a context. One of the primary goals of a theory of conditionals has to be to distinguish correctly between valid and invalid arguments containing conditionals. According to Gauker, an argument is valid if the conclusion is assertible in every context in which the premises are assertible. This runs counter to what Gauker sees as a systematic misreading of the data by other authors, who judge arguments to be invalid if they can think of a context in which the premises are judged true and some other context in which the conclusion is judged false. Different schools of thought on conditionals reflect fundamentally different approaches to semantics. Gauker offers his theory as a motive and test case for a distinctive kind of semantics that dispenses with reference relations and possible worlds. (shrink)

A critique of, and alternative to, the received view of linguistic communication.

Stefano Predelli comes to the defense of the traditional "formal" approach to natural-language semantics, arguing that it has been misrepresented not only by its critics, but also by its foremost defenders. In Contexts he offers a fundamental reappraisal, with particular attention to the treatment of indexicality and other forms of contextual dependence which have been the focus of much recent controversy. In the process, he presents original approaches to a number of important semantic issues, including the relationship between validity and (...) indexicality, the limits of token-reflexive systems, the significance of contextualist arguments, and the interpretation of attitude reports. Contexts will make invigorating reading for all philosophers of language and many linguists. (shrink)

In this paper, the meanings of sentences containing the word or and a modal verb are used to arrive at a novel account of the meaning of or coordinations. It is proposed that or coordinations denote sets whose members are the denotations of the disjuncts; and that the truth conditions of sentences containing or coordinations require the existence of some set made available by the semantic environment which can be ‘divided up’ in accordance with the disjuncts. The relevant notion of (...) ‘dividing things up’ is made explicit in the paper. Detailed attention is given to the question of how the proposed truth conditions are derived from the syntactic input. The account offered allows for the derivation of both the disjunctive and the nondisjunctive readings of modal/or sentences, including the much-discussed free choice readings of may/or sentences.

Philosophers like to talk about propositions. There are many reasons for this. Perhaps the most common is that philosophers are sometimes more interested in the content of a thought or utterance than in the particular sentence or utterance that might express it on some occasion. Propositions are offered as these contents.

This paper is obsolete. It is superseded by the book, Conditionals in Context, MIT Press, 2005.

For many purposes in pragmatics one needs to appeal to a context of utterance conceived as a set of sentences or propositions. The context of utterance in this sense is often defined as the set of assumptions that the speaker supposes he or she shares with the hearer. I argue by stages that this is a mistake. First, if contexts must be defined in terms of shared assumptions, then it would be preferable to define the context as the set of (...) assumptionsthat the interlocutors really do share. Second, not all shared assumptions belong to the context, because not all are relevant. Third, hearers need not accept every member of the context, because some presuppositions are informative. Finally, presupposition coordination problems show that contexts may have contents that even the speaker does not accept. Contexts, we may conclude, are mind-transcendent. In one sense of the term a "presupposition" is an interlocutor's take on this mind-transcendent context. (shrink)

In this book, two related phenomena are studied: presupposition and anaphora. Dynamic semantics is by now widely accepted as a first-rate foundation for such an exercise and it forms the backbone of most of the work in this book. A recurring additional theme of the present book is the usefulness of techniques from partial logic in the treatment of both phenomena. Rather than adding completely new semantic theories to the present gamut of theories, the author discusses a number of existing (...) approaches which aim at accounting for the behavior of presuppositions and/or anaphors, makes improvements where necessary, and compares the results. Presupposition and Anaphora starts with an introduction to a number of dynamic semantic theories and their correlations, paying special attention to the treatment of disjunctions and negations. Subsequently, presuppositions are studied in the context of partial logics, Montague Grammar and dynamic semantics. (shrink)

Writers on presupposition, and on the ‘‘projection problem’’ of determining the presuppositions of compound sentences from their component clauses, traditionally assign presuppositions to each clause in isolation. I argue that many presuppositional elements are anaphoric to previous discourse or contextual elements. In compound sentences, these can be other clauses of the sentence. We thus need a theory of presuppositional anaphora, analogous to the corresponding pronominal theory.

This paper revisits some foundational questions concerning the abstract representation of a discourse context. The context of a conversation is represented by a body of information that is presumed to be shared by the participants in the conversation – the information that the speaker presupposes a point at which a speech act is interpreted. This notion is designed to represent both the information on which context-dependent speech acts depend, and the situation that speech acts are designed to affect, and so (...) to be a representation of context that is appropriate for explaining the interaction of context and the contents expressed in them. After reviewing the motivating ideas and the outlines of the apparatus, the paper responds to a criticism of the framework, and considers the way it can help to clarify some phenomena concerning pronouns with indefinite antecedents.

Recall Grice’s well-worn example from Logic and Conversation about Smith, his girlfriend, and his trips to New York: (1) A: Smith doesn’t seem to have a girlfriend these days. B: He has been paying a lot of visits to NY recently. Grice says that in this dialogue, B implicates that Smith has, or may have, a girlfriend in New York. But in saying this, Grice under-describes his own example. For this proposition alone does not suffice to satisfy the requirements of (...) Relation, the maxim presumed to be operative in this case. Grice says that “[B] implicates that which he must be assumed to believe in order to preserve the assumption that he is observing the maxim of Relation.” But the assumption that B thinks that Smith might have a girlfriend in NY is not in itself sufficient to render B’s utterance relevant. An additional assumption is required, one which explicitly links the issue of having girlfriends to the issue of travel to NY: perhaps, the proposition that a person who has a girlfriend somewhere travels there frequently; or that many people have long-distance relationships, and these involve frequent trips to the same place. If A can work out that B is making this supposition, then she can immediately see the relevance of B’s response to her remark. Without it, relevance cannot be established. So this general background assumption must be implicated by the utterance.1 Now, this background assumption is not enough by itself to guarantee relevance. Suppose that B believes the background assumption, but does not believe that Smith might be traveling to NY to visit a girlfriend. Then his utterance is still in violation of Relation. B should invoke the background assumption only if it is relevant itself. (shrink)
