Ryan stated a couple of facts on preventing certain types of representation from forming the focus of interest or macrostructure of a story. He also stated that it does not mean that these representation cannot appear in a narrative text, but rather they cannot, all by themselves, support its narrative.
He made a couple of list such as eliminating representation of abstract entities and entire classes of concrete objects, scenarios involving “the human race”, “reason”, “the State”, “atoms”, “the brain”, etc. I thought he made a good point such as this because if involving all these materials would make the narrative being very dragged. It isn’t necessary to include all of these. The another thing he state was to remove static descriptions. I might have to disagree a little bit. I thought certain stories would be good to include some static descriptions… IF.. they’re planning to use it. Else I’m one hundred percent on Ryan’s thoughts. Most of all…. eliminate BAD stories. This is the most controversial condition in the list because it straddles the borderline between definition and poetics.
Anyways, this article about How and When to use Narrative seems like a pretty nice read as well. Short and simple.
