Newt may be young, but he is not ignorant. His repetition of the line "See the cat? See the cradle?", is not by accident. Vonnegut's title ties right into this line, and undoubtedly is meant to help convey his views of postmodernism. Vonnegut uses the concept of a cat's cradle, the unsolvable hand and string game that looks nothing like how it is described to be a symbolic image for the postmodern view on life.
This view appears to make sense in our ever evolving world. Knowledge is a limitless factor now. There is not one way to learn everything, and in Cat's Cradle, Vonnegut mocks the idea of there being one way. For instance, he traverses the tricky subject of religion. In real life, religion is hard to describe. Everyone has their own viewpoint in one way or another on the subject, and it seems more of a personal aspect of life than anything else. Yet, there are those who attempt to make it a universal way of thinking. This violates postmodern theory. Personally, I feel that the postmodern concept of life is a more enlightened way of viewing things. Just as Vonnegut metaphorically portrays a closed mind way of thinking as a cat's cradle, postmodernism justifies it in the same way. There is no solvable end to a cat's cradle, and in the same way there is no correct answer for life. Truth is nonexistent. It is simply what we chose to believe that we make the truth. There are too many ways, whether religious views, or just walks of life, to justify one as being correct, and those who attempt to make one way right will never win. In this life we have a choice, and acceptance of everyone, whether you are religious or not, will be the only way to coexist peacefully in a world where a collision of values, religion, and society takes place on a daily basis.
