In this groundbreaking work of 20th-century philosophy, J.L. Austin reshapes our understanding of language and its power-not merely to describe the world, but to act within it. Based on a series of lectures delivered at Harvard University, How to Do Things with Words introduces the now-famous theory of "speech acts," revealing how utterances can function as actions-promising, ordering, naming, or apologizing-rather than simply stating facts. Austin's clear and witty style, combined with his rigorous analysis, makes this a foundational text for anyone interested in language, philosophy, linguistics, law, or communication. Far from being abstract theory, Austin's ideas have reverberated across fields as diverse as political theory, literary criticism, artificial intelligence, and everyday social interaction.
