Postmodernism is a belief forged in the fires of destruction.  After WW II many people, disgusted with the mayhem and destruction created by our advancing technology, sought a new lifestyle, one that would seek to counteract the old ways that led to the massive violence and destruction (Potash).  That lifestyle was Postmodernism, this belief rejected all of the old beliefs in an attempt to protect the world from destruction (Potash).  In this rejection, however, they created destruction, this time in the form of ideals and culture.  The Fountain, Fight Club, and Wikipedia all illustrate the destruction of ideals, which are beauty, culture, and truth respectively.  While Catch-22 depicts the Postmodernist opinion of war and violence in regards to destruction as well as the destruction of logic and sense.
