For Derrida, as for all Superstructuralists, language constitutes the human world and the human world constitutes the whole world. So, by the same progression that leads from Saussurean linguistics to general Semiotics, Derrida expands his theory of language into a philosophy of the world as language. Only now, of course, language and world are to be conceived in terms of Writing rather than in terms of 'langue'. When Derrida displaces objective things and subjective ideas from their traditional priority, it is Writing that he puts ahead of them.
