Abstract for Green's essay which he repeats (sort of) in "Essays on Grice"

Grice's Frown:

"Paul Grice's writings suggest that he views conversational implicature as a species of speaker meaning, and many writers concerned with implicature have endorsed that suggestion. The myriad challenges facing the explication of speaker meaning raise some doubt, however, whether it is an adequate framework for the notion of conversational implicature. In particular, the "reflexive communicative intentions" (intentions to produce an attitude in an audience by means of the audience's recognition of those very intentions) that Grice and his followers have taken to be crucial to speaker meaning do not, on closer scrutiny, seem to be necessary features of that concept at all. I argue first that reflexive communicative intentions are not necessary for conversational implicature. Next, the Gricean framework for speaker meaning is used to throw into relief a pervasive feature of communication that is invoked in a wide variety of philosophical discussions (as well as in the arts, in social psychology, psycholinguistics, and linguistics) but little explicated, namely the notion of expression. That notion is then shown to be important for another area of inquiry than that of implicature, particularly for our account of the phenomenon of Moorean absurdity. Finally, I argue that the notion of expression, construed as intentionally and overtly showing one's intentional state, is a core concept in terms of which conversational implicature may be understood."
