Ordinary language philosophy is a philosophical methodology that sees traditional philosophical problems as rooted in misunderstandings philosophers develop by distorting or forgetting what words actually mean in everyday use. "Such 'philosophical' uses of language, on this view, create the very philosophical problems they are employed to solve." Ordinary language philosophy is a branch of linguistic philosophy closely related to logical positivism.
This approach typically involves eschewing philosophical "theories" in favor of close attention to the details of the use of everyday "ordinary" language. It is sometimes associated with the later work of Ludwig Wittgenstein and a number of mid-20th century philosophers that can be split into two main groups, neither of which could be described as an organized "school". In its earlier stages contemporaries of Wittgenstein at Cambridge University such as Norman Malcolm, Alice Ambrose, Friedrich Waismann, Oets Kolk Bouwsma and Morris Lazerowitz started to develop ideas recognisable as ordinary language philosophy. These ideas were further elaborated from 1945 onwards through the work of some Oxford University philosophers led initially by Gilbert Ryle, then followed by J. L. Austin. This Oxford group also included H. L. A. Hart, Geoffrey Warnock, J. O. Urmson and Peter Strawson. The close association between ordinary language philosophy and these later thinkers has led to it sometimes being referred to as "Oxford philosophy". More recent philosophers with at least some commitment to the method of ordinary language philosophy include Stanley Cavell, John Searle and Oswald Hanfling.
