Good art is a truing of vision, in the way a saw is trued in the saw shop, to cut more cleanly. It is also a changing of vision. Entering a good poem, a person feels, tastes, hears, thinks, and sees in altered ways. Why ask art into a life at all, if not to be transformed and enlarged by its presence and mysterious means? Some hunger for more is in us—more range, more depth, more feeling; more associative freedom, more beauty. More perplexity and more friction of interest. More prismatic grief and unstunted delight, more longing, more darkness. More saturation and permeability in knowing our own existence as also the existence of others. More capacity to be astonished. Art adds to the sum of the lives we would have, were it possible to live without it. And by changing selves, one by one, art changes also the outer world that selves create and share.
