Grice's Implicatum

"An approach is provided to the prediction and explanation of quantity implicata (implicata whose calculation depends on aversion to Grice's maxim of Quantity) that, unlike the majority of approaches available, does not construe Quantity as requiring speakers to make the strongest claim that their evidence permits. Central to this treatment is an elaboration of the notion of what a conversation requires as appealed to in the Cooperative Principle and the Quantity maxim."
