I had a teacher I liked who used to say good fiction’s job was to comfort the disturbed and disturb the comfortable. I guess a big part of serious fiction’s purpose is to give the reader, who like all of us is sort of marooned in her own skull, to give her imaginative access to other selves. … We all suffer alone in the real world; true empathy’s impossible. But if a piece of fiction can allow us imaginatively to identify with a character’s pain, we might then also more easily conceive of others identifying with our own. This is nourishing, redemptive; we become less alone inside.
