A paper illustrates this set of concepts with the idea of a cook asking for sugar not expecting a “trick spoon made of rubber” or “a good book.” Geoffrey Leech expanded on Robin Lakoff’s proposed variant of this set of concepts, which includes giving options. Under a “Neo” theory named for their originator, these concepts can be replaced by Horn’s lower-bounding Q-principle and upper-bounding R-principle. A member of this set of concepts titles a book by (*) Deirdre Wilson and Dan Sperber that argues the other three are not needed. (10[1])The formulator of these (-5[1])concepts contrasted the effects of violating and flouting them. (10[1])Implicatures (-5[1])arise due to this set of rules introduced (10[1])in “Logic and Conversation,” which delineate aspects of the cooperative principle. (10[1])For 10 points, name this set of four principles (10[1])in pragmatics that govern everyday speech, including (10[1])quantity, quality, relation, and manner. ■END■
