The provenance of art can never be as morally elementary as we wish it. Art grows from the world, and the world, as Louis MacNeice said, is incorrigibly plural. This cruel but consoling fact really shows up when you start the slide to nowhere. The air is lit by a shimmering tangle of all the reasons you are sad to go and all the reasons you are glad to leave. It’s the glow of life: apparently simple, yet complex beyond analysis.
