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.

The pragmatic framework developed by H.P. Grice in “Logic and Conversation” explains how a speaker can mean something more than, or different from, the conventional meaning of the sentence she utters. But it has been argued that the framework cannot give a similar explanation for cases where these pragmatic effects impact the understood content of an embedded clause, such as the antecedent of a conditional, a clausal disjunct, or the clausal complement of a verb. In this paper, I show that such an explanation is available. One of the central arguments of the paper is that in a significant subset of cases, local pragmatic effects are a consequence of a global pragmatic requirement. In these cases, local pragmatic effects are a consequence of ‘acting locally’ to resolve a potential global pragmatic violation. These cases do not require us to posit application of pragmatic principles to the contents of embedded clauses. The account does, though, require the assumption that interpreters can identify and reason about the contents of unasserted sub-parts of sentences, an assumption that I motivate in section 3. Building on this, in section 4 of the paper, I argue that once we have recognized that interpreters can, and do, reason independently about the contents of non-asserted clauses, it becomes unproblematic to assume that in some cases, Gricean conversational principles do apply directly to these contents, providing an alternative route to account for local pragmatic effects. In revisiting the ideas of this paper in my response to the commentaries, I consider in more detail the revisions to Grice’s broader program that are necessitated by these moves, in particular acknowledging the problematicity of Grice’s notion of what is said. I argue that the starting point for Gricean reconstructions should instead be merely what is expressed, which carries no pragmatic commitments regarding what is speaker meant.

This paper concerns what might be called the variably bad behavior of the word or. As is well known, there are a variety of environments in which the word or misbehaves – misbehaves, in the sense that it gives rise to interpretations which are not expected given the standard analysis of this word as, roughly, set union. One of these environments is the scope of a modal. This case has received a lot of attention recently in the literature, and a number of researchers, including myself, have proposed accounts of or which explain its behavior in this environment.

The current literature on presupposition focuses almost exclusively on the projection problem: the question of how and why the presuppositions of atomic clauses are projected to complex sentences which embed them. Very little attention has been paid to the question of how and why these presuppositions arise at all. As Kay (1992, p.335) observes, “treatments of the presupposition inheritance problem almost never deal with the reasons that individual words and constructions give rise, in the first place, to the particular presuppositions that they do.”1 This is the question on which this paper will focus.

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.

Since linguists began extensive work on presupposition in the 1970's, a long and heterogeneous list has been compiled of expressions, expression types and constructions that give rise to presuppositions. In the current literature, the principal (but by no means sole) diagnostic for presupposition typically appealed to is the tendency of the particular element of meaning to project, i.e. to escape the scope of operators such as negation, the question operator, or modals. An important intuition also routinely appealed to is that the element of meaning is in some sense backgrounded, or treated by the speaker as taken for granted. There seems little doubt that there are interesting and theoretically relevant distinctions to be made between different types of presuppositions within this heterogeneous set. But the study of these distinctions is of interest primarily in light of the intuition that the members of this set share some common feature: that there is some singular phenomenon of presupposition to be described and explained. This paper is concerned with what presuppositions have in common, and offers an alternative to the current standard view. On the view currently prevalent in the linguistic literature, presuppositions constitute constraints on the common ground, or on an interlocutor’s “take” on the common ground, at the point at which 1 the presupposing utterance is interpreted. I do not intend to offer here a detailed critique of this standard theory, but perhaps a few words of justification are in order. The motivation for seeking a new account comes in part from the same considerations cited by Abbott 2000, in her critique of the standard view. Abbott’s central point is that the driving idea behind the common ground view is that presuppositions are identified with “old” information, or information that the speaker is treating as “old.” This idea, while perhaps helpful as an initial approximation, rapidly runs up against the observation that it is normal and commonplace for....
