Paul Grice
Herbert Paul Grice (1913 - 1988), often writing under the name Paul Grice, was a philosopher remembered mainly for his substantial contribution to the study of meaning within language, particularly his cooperative principle, the maxims of conversation derived from the cooperative principle, and his theory of implicatures. Grice's work is one of the foundations of the modern study of pragmatics. He proposed an intention-based theory of meaning, in which 'A meant something by x' is roughly equivalent to 'A uttered x with the intention of inducing a belief by means of the recognition of this intention'. Many of his essays/papers were published in the book Studies in the Way of Words (1989).
