On Grice and cancellation

In response to Robyn Carston's (2010) defence of explicature as cancellable, the paper examines what Grice meant by ‘cancellable’. It offers reasons for thinking that only generalised conversational implicatures are cancellable, not relevance theory's explicatures and not particularised conversational implicatures. It concludes by questioning relevance theory's re-analysis of Grice's GCIs as explicatures.
