Curiously enough, one cannot read a book; one can only reread it. A good reader, a major reader, and active and creative reader is a rereader.
When you reread a classic you do not see more in the book than you did before; you see more in you than there was before.
My definition of good literature is that which can be read by an educated reader, and reread with increased pleasure.
The ultimate luxury is to reread: to revisit a book to see how time has treated it, how memory has distorted it, or how my own passing years have cast a new light on it.
Lists of books we re-read and books we can't finish tell more about us than about the relative worth of the books themselves.
