Discourse Analysis derives from a paradigm shift in philosophy, Twentieth-century philosophy moved from taking a view about the world and its properties expressed through language, to a focus on language and its properties as such, and how the world is made for us from the meanings that language expresses, This represents an Inversion of the scientific and commonsensical world- view inherited from the scientific revolution and empiricist philosophies of the last few hundred years, In that perspective language is simply a neutral medium through which facts and meanings can in principle be transparently conveyed (Shapiro, 1985-86).
Perhaps the clearest expression of this outlook in philosophical terms is in the first chapter of Richard Rorty's (1989) Contingency, Irony and Solidarity, where he explains that - with the death of God - we can no longer assume that the universe contains meanings that are just ‘there’ to be construed by us in language. That is, we have no reason to believe that the world ‘has a human face’ which it turns to us, and which we can interpret through language as a neutral medium, Rather we use language to inscribe meanings into the world - whether into or onto objects, or experiences - and then we read those meanings back to ourselves as if they had always resided in the objects or experiences as such.
