Abstract for Frapolli Sanz in the Theorema issue for Grice

"The aim of this paper is to show that the meaning of a certain group of expressions, inference markers, which are usually credited as conventional-implicature triggers, can be explained in a way that is both independent of any other levels of meaning -- what is said, what is conversationally implicated, and what is presupposed -- and compatible with truth-conditional pragmatics (TCP). TCP is one of the theories of meaning that best represent the Gricean spirit, as expressed by two of the main theses of his philosophy, already present in "Meaning". We will focus on the study of conventional implicatures involving the use of the connective 'but' between two concepts."
