 Pragmatics deals with utterances, by which we will mean specific events, the intentional acts of speakers at times and places, typically involving language. Logic and semantics traditionally deal with properties of types of expressions, and not with properties that differ from token to token, or use to use, or, as we shall say, from utterance to utterance, and vary with the particular properties that differentiate them. Pragmatics is sometimes characterized as dealing with the effects of context. This is equivalent to saying it deals with utterances, if one collectively refers to all the facts that can vary from utterance to utterance as ‘context.’ One must be careful, however, for the term is often used with more limited meanings.
