"I believe there is one story in the world, and only one, that has frightened and inspired us, so that we live in a Pearl White serial of continuing thought and wonder. Humans are caught--in their lives, in their thoughts, in their hungers and ambitions, in their avarice and cruelty, and in their kindness and generosity too--in a net of good and evil. I think this is the only story we have and that it occurs on all levels of feeling and intelligence. Virtue and vice were warp and woof of our first consciousness, and they will be the fabric of our last, and this despite any changes we may impose on field and river and mountain, on economy and manners. There is no other story. A man, after he has brushed off the dust and chips of his life, will have left only the hard, clean questions: Was it good or was it evil? Have I done well--or ill?"

From Chapter 34, Steinbeck's East of Eden.
