We review Potts’ influential book on the semantics of conventional implicature (CI), offering an explication of his technical apparatus and drawing out the proposal’s implications, focusing on the class of CIs he calls supplements. While we applaud many facets of this work, we argue that careful considerations of the pragmatics of CIs will be required in order to yield an empirically and explanatorily adequate account.

Grice’s distinction between what is said and what is implicated has greatly clarified our understanding of the boundary between semantics and pragmatics. Although border disputes still arise and there are certain difficulties with the distinction itself (see the end of §1), it is generally understood that what is said falls on the semantic side and what is implicated on the pragmatic side. But this applies only to what is..

I argue that conventional implicatures embed in logical compounds, and are non-truth-conditional contributors to sentence meaning. This, I argue has significant implications for how we understand truth, truth-conditional content, and truth-bearers.

Are all instances of the T-schema assertable? I argue that they are not. The reason is the presence of conventional implicature in a language. Conventional implicature is meant to be a component of the rule-based content that a sentence can have, but it makes no contribution to the sentence's truth-conditions. One might think that a conventional implicature is like a force operator. But it is not, since it can enter into the scope of logical operators. It follows that the semantic (...) content of a sentence is not given simply by its truth-conditional content. So not all instances of the T-schema are assertable in the relevant sense. Consequently, there is a strong case to be made against truth-conditional semantics of the disquotational variety and deflationism about truth. (shrink)

Scalar implicatures depend on alternatives in order to avoid the symmetry problem. I argue for a structure-sensitive characterization of these alternatives: the alternatives for a structure are all those structures that are at most as complex as the original one. There have been claims in the literature that complexity is irrelevant for implicatures and that the relevant condition is the semantic notion of monotonicity. I provide new data that pose a challenge to the use of monotonicity and that support the (...) structure-sensitive definition. I show that what appeared to be a problem for the complexity approach is overcome once an appropriate notion of complexity is adopted, and that upon closer inspection, the argument in favor of monotonicity turns out to be an argument against it and in favor of the complexity approach.

This article presents evidence that individual words and phrases can contribute multiple independent pieces of meaning simultaneously. Such multidimensionality is a unifying theme of the literature on conventional implicatures and expressives. I use phenomena from discourse, semantic composition, and morphosyntax to detect and explore various dimensions of meaning. I also argue that, while the meanings involved are semantically independent, they interact pragmatically to reduce underspecification and fuel pragmatic enrichment. In this article, the central case studies are appositives like Falk, the (...) CEO, and the taboo intensive damn, though discourse particles and connectives like but, even, and still play supporting roles. The primary evidence, both quantitative and qualitative, is drawn from large interview and product-review corpora, which harbor a wealth of information about the importance of these items to discourse.

We define a notion of projective meaning which encompasses both classical presuppositions and phenomena which are usually regarded as non-presuppositional but which also display projection behavior—Horn’s assertorically inert entailments, conventional implicatures (both Grice’s and Potts’) and some conversational implicatures. We argue that the central feature of all projective meanings is that they are not-at-issue, defined as a relation to the question under discussion. Other properties differentiate various sub-classes of projective meanings, one of them the class of presuppositions according to Stalnaker. (...) This principled taxonomy predicts differences in behavior unexpected on other models among the various conventional triggers and conversational implicatures, while holding promise for a general, explanatory account of projection which applies to all the types of meanings considered.

The paper argues that the correct definition of lying is that to lie is to assert something one believes to be false, where assertion is understood in terms of the notion of the common ground of a conversation. It is shown that this definition makes the right predictions for a number of cases involving irony, joking, and false implicature. In addition, the proposed account does not assume that intending to deceive is a necessary condition on lying, and hence counts so-called (...) bald-faced lies as lies. (shrink)

In this paper, I defend against a number of criticisms an account of slurs, according to which the same semantic content is expressed in the use of a slur (e.g. 'chink') as is expressed in the use of its neutral counterpart (e.g. 'Chinese'), while in addition the use of a slur conventionally implicates a negative, derogatory attitude. Along the way, I criticise competing accounts of the semantics and pragmatics of slurs, namely, Hom's 'combinatorial externalism' and Anderson and Lepore's 'prohibitionism'.
