Sven Birkerts said this quote

I often find that a novel, even a well-written and compelling novel, can become a blur to me soon after I've finished reading it. I recollect perfectly the feeling of reading it, the mood I occupied, but I am less sure about the narrative details. It is almost as if the book were, as Wittgenstein said of his propositions, a ladder to be climbed and then discarded after it has served its purpose.
