'This is where an editor steps in, a reader invested in the text but also distant enough from it to see it analytically and manipulatively. To prove this point: my best editors have been those who saw in my drafts something I had not seen myself, who pointed out to me the hidden (from me, the author) lacunae where the text could grow—or redundancies that had to be cut altogether.'
