So breakdown of genre is the moment of possible discovery. Genre is just the superficial manifestation. People get used to looking at genre for guarantees. When those sorts of distinctions weaken, it can be unnerving. And that's the terrifying moment that can lead to revelation.
Nonfiction associates itself with the exterior world and fiction presumably deals with sensibility.
There's a point where those things do and must meet. Different values, different world views are implied in each answer. Not just a matter of style, not just a matter of craft. And there's a move eventually through Seurat to a certain kind of field abstraction. Whatever value I find in totally non-representational painting or in totally representational painting, the moment of collision is the one where I get the biggest charge.
