Relevance Implicatures Robert van Rooy∗ ILLC/University of Amsterdam
[email protected] Abstract According to standard pragmatics, we should account for conversational implicatures in terms of Grice’s (1967) maxims of conversation. Neo-Griceans like Atlas & Levinson (1981) and Horn (1984) seek to reduce those maxims to the so-called Q and I-principles. In this paper I want to argue that (i) there are major problems for reducing Gricean pragmatics to these two principles, and (ii) in fact, we can better account for implicatures by means of an exhaustivity operator defined in terms of a relevance-based ordering relation. 1 Introduction In most circumstances we infer from the fact that the (a) sentences of the following examples are uttered that the (b) sentences are true: (1) a. John ate some of the cookies. b. John didn’t eat all of the cookies (2) a. John is coming or Mary is going. b. John is coming or Mary is going, but not both. (3) a. John is walking, if Mary is talking. b. John is walking if and only if Mary is talking. ∗This note reports on work in progress on the use of relevance for the semantic analysis of natural language. Parts of this paper was presented at the second workshop on Optimality Theoretic Semantics at OTS in Utrecht (2000) and at the Formal Pragmatics conference in Berlin (2001). I would like to thank the participants of those events for their comments and suggestions. I would also like to thank the anonymous reviewers, Reinhard Blutner and expecially Katrin Schulz.
