Modernism is all about the truth and finding one central purpose to live by and believe in.....while Postmodernism suggests that we as a civilization must deviate away from the concept of modernism because there is no one truth and trying to pursue that will only lead to chaos.  Trying to create conformity among the masses will create progress to some extent but it will also lead this "progress" down the wrong path. The book title itself, Cat's Cradle, represents postmodernism in all aspects.  As described in the book we come to realize that the Cats Cradle is the oldest game known to man, presenting no form or end to this mess of string they call a game. This book also brings the theory of having a utopia to light. The struggles of having a utopia are put to focus in the Cats Cradle and the risks of making a perfect society is far more dangerous than the reward. Therefore, establishing a single grand narrative in society is futile.  Vonnegut expresses this point through the use of his characters.  Newt is a midget, while his sister is a giant, and together they have a radical brother-not exactly a stereotypical American family from the mid twentieth century.  In addition, Vonnegut uses Newt to display that society is filled with masked lies that conform to fit the grand narrative. In all aspect the Grand Narrative is Bokonon there religion and foma which is lies made to make the believers of bokononism to believe there doing the right thing.
