Poetry is a city of words, a complex heterogeneity that functions both as its parts and as a whole. It’s full of systems—metaphoric, symbolic, sonic—analogous to the sewage, electrical, and transportation systems that animate a city. You look at a jagged skyline, and see the ragged right margin; you read through the quick shifts of much contemporary poetry, and think of a busy intersection in which your view is cut off by a bus one moment, then opened up the next, and then filled with a crowd crossing the street the next.
