Katherine Dunn on non-fiction vs. fiction:
"Non-fiction is a big responsibility. Rationality. Facts. The urgent need to reflect some small aspect of reality. But fiction is a private autism, a self-referential world in which the writer is omnipotent. Gravity, taxes and death are mere options, subject to the writer’s fancy. Fiction, even when it’s grim and hard, is fun."
