The question arises: Is telling a story better than telling a non-story? No. Stories are not “better” than any other form of communication — just different. To see this difference we need to define “story” so we can tell what a story is and what it is not. Herein lies a political problem. No matter how one defines “story,” there will be an author someplace who finds his favorite work has been defined out, and feels it is somehow diminished by not being classified as a story. Rather than risk the ire of countless creative authors, we have limited our definition to a very special kind of story: the Grand Argument Story.
As its name indicates, a Grand Argument Story presents an argument. To be Grand, the argument must be a complete one, covering all the ways the human mind might consider a problem and showing that only one approach is appropriate to solving it. Obviously, this limits out a lot of creative, artistic, important works — but not out of being stories, just out of being Grand Argument Stories. So, is a Grand Argument Story better than any other kind? No. It is just a specific kind.
