Atonement

by Ian McEwan

That night creatures were drawn to lights where they could be most easily eaten by other creatures was one of those mysteries that gave her modest pleasure. She preferred not to have it explained away. At a formal dinner once a professor of some science or other, wanting to make small talk, had pointed out a few insects gyrating above a candelabra. He had told her that it was the visual impression of an even deeper darkness beyond the light that drew them in. Even though they might be eaten, they had to obey the instinct that made them seek out the darkest place, on the far side of the light—and in this case it was an illusion. It sounded to her like sophistry, or an explanation for its own sake. How could anyone presume to know the world through the eyes of an insect? Not everything had a cause, and pretending otherwise was an interference in the workings of the world that was futile, and could even lead to grief. Some things were simply so.
