"Fiction - with its redolent details, imaginative metaphors and attentive descriptions of people and their actions - offers an especially rich replica. Indeed, in one respect novels go beyond simulating reality to give readers an experience unavailable off the page: the opportunity to enter fully into other people's thoughts and feelings.
The novel, of course, is an unequaled medium for the exploration of human social and emotional life. And there is evidence that just as the brain responds to depictions of smells and textures and movements as if they were the real thing, so it treats the interactions among fictional characters as something like real-life social encounters."
