"Any discourse that was out to uncover and question that system had to find a language, a style, that broke from the constraints of common sense and ordinary language. Theory set out to produce texts that could not be processed successfully by the commonsensical assumptions that ordinary language puts into play. There are texts of theory that resist meaning so powerfully - say those of Lacan or Kristeva - that the very process of failing to comprehend the text is part of what it has to offer."
