To claim that literature on its own is going to change reality would be an act of madness or arrogance. It seems to me no less foolish to deny that it can aid in making this change.
People interested in putting together a very restricted canon of great books don't really like reading; true readers, among whom I have the impertinence to include myself, are always sniffing out more and more titles. Reading is a hobby that never grows stale--and an unpunished vice.
I look at every detail of rooms I imagine. If it is not there, I conjure it up. I inhabit the room and experience the noises, smells, and personal details. I work toward emotional verisimilitude in all the details of experience -- the way it happened, even though this is something that in reality has never happened.
