Speech Act Theory

framework · linguistics · structured-empirical

Austin and Searle's framework: utterances perform actions (locutionary, illocutionary, perlocutionary).

Speech Act Theory is the pragmatic framework analyzing utterances as performances of actions rather than merely as descriptions of states of affairs, articulated by J.L. Austin in his foundational 1955 William James Lectures at Harvard (published posthumously as How to Do Things with Words 1962) and substantially developed by John Searle (Speech Acts 1969). Austin's central observation: many utterances ('I promise to call you,' 'I name this ship the Queen Elizabeth,' 'I now pronounce you married') don't describe pre-existing states but rather perform actions through their utterance — what Austin initially called 'performatives' as opposed to 'constatives,' before his subsequent analysis showing all utterances have action-performing dimensions. Austin's three-level analysis: (1) Locutionary act — the utterance itself with its conventional meaning (what is said); (2) Illocutionary act — the action performed in saying it (assertion, promise, request, command, naming, etc. — the illocutionary force); (3) Perlocutionary act — the effects produced by saying it (persuading, convincing, scaring, amusing the hearer). Searle substantially systematized speech act theory with: typology of illocutionary acts (assertives, directives, commissives, expressives, declarations); felicity conditions (preparatory, sincerity, propositional content, essential conditions specifying what makes a particular speech act successful); indirect speech acts (saying one thing while meaning another, e.g., 'Can you pass the salt?' as request rather than question). The framework substantially shaped pragmatics, philosophy of language, legal theory (J. L. Austin's analysis influenced legal-philosophical work on performatives in contracts and constitutive utterances), and broader analytical philosophy. Recent applications include AI/NLP work on dialogue systems, speech act recognition, and formal semantics-pragmatics interfaces.
