John Irving said this quote

“ Novels were not arguments; a story worked, or it didn't, on its own merits. What did it matter if a detail was real or imagined? What mattered was that the detail seemed real, and that it was absolutely the best detail for the circumstance. That wasn't much of a theory, but it was all Ruth could truly commit herself to at the moment. It was time to retire that old lecture, and her penance was to endure the compliments of her former credo. ”
