Lyotard's "The PostModern Condition", is an exciting atttempt at a postmodern Sociology of Knowledge. Using Weberian and Habermasian concepts of legitimation, Lyotard gices a critique of critique, showing how all forms of knowledge are, in the end, dependent on the Narrative, the story which humansociety tells of itself. From this Levi-Straussian concept, Lyotard builds an interesting framework for Modern, PostModern and Futuristic definitions of knowledge. So why did I give the book only 4 stars? Because Lyotard fails inhis attempts at encorparating Anglo-American philosophy into the book. His total misconception of Wittgenstein can be flabbergasting to anyone who's studied this tradition of philosophy. Still, the book is probably the easiest of its type to understand and it is quite enjoyable to read. But it's a good idea to supplement it with some Foucault and some Habermas.
