When I looked, I knew I might never again see so much of the earth so beautiful, the beautiful being something you know added to something you see, in a whole that is different from the sum of its parts. What I saw might have been just another winter scene, although an impressive one. But what I knew was that the earth underneath was alive and that by tomorrow, certainly by the day after, it would be all green again. So what I saw because of what I knew was a kind of death with the marvellous promise of less than a three-day resurrection.
