In the middle of the Twentieth century J.L. Austin subjected language to a close and intense analysis. This book deals with his examination of the various things we do with words, comparing his work with that of more recent philosophers and social scientists. It shows that his work can still play a vital role in enhancing our understanding of language. It also deals with the philosophical insights that Austin believed could be gained by closely examining the uses of words by non-philosophers. The school of thought that Austin's name is usually linked with – 'ordinary language philosophy' – is often overlooked today. This book contains both criticisms of Austin's philosophical work where he used this approach, and defences of it that aim to show that it can still be a source of valuable insights.
