The Seven Self-Contradictions of Postmodernism

[derrida]

I think Lyotard is encouraging us to be skeptical of his own statements- from the English translations of his work that I've read it doesn't seem as if he is assigning any special privilege to his own ideas.

My own understanding of the metanarrative is more foucauldian, though- that is to say that it is the manner in which knowledge is used to accomplish various objectives that is most important in finding a definition of the concept.

That said, there's a tricky bit of epistemology that goes into disproving a statement using its own assumptions.
