I suddenly had a picture of the entire astonishing edifice (of modern scientific knowledge) collapsing and modern man plunging headlong back into the primordial ooze. He’s floundering, sloshing about, gulping for air, frantically treading ooze, when he feels something huge and smooth swim beneath him and boost him up, like some mighty dolphin. He can’t see it, but he’s much impressed. He names it God.
