Herbert Paul Grice (b. 1913–d. 1988) was a British philosopher and linguist, and one of the pivotal figures in philosophy during the 20th century. He wrote in many areas of philosophy, including the metaphysics of personal identity, logical paradoxes, the analytic/synthetic distinction, the philosophy of perception, philosophical psychology, and ethics. He also wrote on historical figures such as Aristotle, Descartes, Hume, and Kant. But his most significant contributions came in philosophy of language and mind, on meaning, intention, presupposition, conversation, and the theory of communication. Grice argued for an intention-based theory of meaning, and he was the first to illustrate the distinction between what came to be called semantic and pragmatic meaning, that is, between what a speaker’s utterance (or its utterance “type”) means in the abstract, and what else a speaker can mean by uttering it in a particular context. Grice highlighted this by an appeal to his framework of the Cooperative Principle and its Conversational Maxims, which are plausibly assumed by conversational participants and provide mechanisms for the ways in which speakers can “conversationally implicate” something beyond the literal meaning of what they say, and for how hearers can recover those “implicatures.’” Grice’s enduring influence on these topics helped found the burgeoning discipline in philosophy of language and linguistics now known as “pragmatics” (compare the Oxford Bibliographies in Philosophy article on “Pragmatics”).
