Abstract
We may begin with Grice’s view. In an extended series of papers, a number of which are unpublished, Grice sought to explicate what it is for a given utterance to mean something—in the way in which linguistic utterances mean something; and what it is for a given speaker to mean something by his utterance—again, in the way in which speakers mean something in speaking their language. "Utterance" we may understand as neutrally as possible, as a bearer of meaning—in Grice’s sense, "non-natural meaning". One of the distinguishing marks of meaningNN is given as follows: that, of an utterance x, "x means that p and x meant that p do not entail p."
