Grice, "Implicatura"

"The main aim of this paper is to evaluate the implicature theory for epistemic contexts, as an attempt to save the validity of the principle of substitution in those contexts. I defend that Recanati's arguments against the implicature theory are not conclusive because they are based on inadequate examples and on unclear interpretations of Grice's writings. I then argue that the mixing up of theories of meaning and attitude ascription with the classical intuitions held by Fregeans against Russellians in these contexts does not give promising results"
