The same day, I ran across a quotation from Vladimir Nabokov on the Internet: “Curiously enough,” the author of Lolita tells us, “one cannot read a book: one can only reread it.” Intrigued by this paradox, I checked out the essay it came from. “When we read a book for the first time,” Nabokov complains, “the very process of laboriously moving our eyes from left to right, line after line, page after page, this complicated physical work upon the book, the very process of learning in terms of space and time what the book is about, this stands between us and artistic appreciation.” Only on a third or fourth reading, he claims, do we start behaving toward a book as we would toward a painting, holding it all in the mind at once.
