Cultural studies doesn't waste time creating and defending so-called rigorous, objective, analytical methodologies, just as it wastes no time in pretending it is employing a universal, absolute Reason or any system of logic based on an independent critical reason. We attempt to describe our own life-world. We attempt to describe prevalent discourses that shape our social world. We trace the effects of chaos, and how the social order attempts to defuse such chaos. A major difference between Cultural Studies and empirical explanation is that the postmodernist never comes to some stable place of closure .
Representations are always in motion, and so conclusion or closure is never warranted.
None of these stories can validate themselves as reality and disprove all the others. Reason and its minions, logic, and statistics, work all sides equally well. It all depends on time and place. The final purpose of postmodernism is to give us the tools to escape from over-bearing master narratives. The goal is freedom.
