By contrast, Wittgenstein would later describe his task as bringing "words back from their metaphysical to their everyday use".[3] The sea-change brought on by his unpublished work in the 1930s centered largely on the idea that there is nothing wrong with ordinary language as it stands, and that many traditional philosophical problems were only illusions brought on by misunderstandings about language and related subjects. The former idea led to rejecting the approaches of earlier analytic philosophy – arguably, of any earlier philosophy – and the latter led to replacing them with the careful attention to language in its normal use, in order to "dissolve" the appearance of philosophical problems, rather than attempt to solve them. At its inception, ordinary language philosophy (also called linguistic philosophy) had been taken as either an extension of or as an alternative to analytic philosophy.
