The unsaid, for me, exerts great power: often I wish an entire poem could be made in this vocabulary. It is analogous to the unseen; for example, to the power of ruins, to works of art either damaged or incomplete. Such works inevitably allude to larger contexts; they haunt because they are not whole, though wholeness is implied: another time, a world in which they were whole, or were to have been whole, is implied. There is no moment in which their first home is felt to be the museum. A few years ago, I saw a show of Holbein drawings; most astonishing were those still in progress. Parts were entirely finished. And parts were sketched, a fluent line indicating arm or hand or hair, but the forms were not filled in. Holbein had made notes to himself: this sleeve blue, hair, auburn. The terms were other-not the color in the world, but the color in paint or chalk. What these unfinished drawings generated was a vivid sense of Holbein at work, at the sitting; to see them was to have a sense of being back in time, back in the middle of something. Certain works of art become artifacts. By works of art, I mean works in any medium. And certain works of art do not. It seems to me that what is wanted, in art, is to harness the power of the unfinished.
