This is pop philosophy and not serious political thought. If Orwell read this he would have eaten it and then puked it out projectile vomit style. It is the postmodern writing that so terrifies Sokal. All of that being said, it is damned fun to read. Just don't take it too seriously. People who fall deeply into this stuff become pretentious hipster assholes. The introduction by Foucault is important if you want any chance in understanding this mess. It sure could use more footnotes.
