"So what shall I make of the voice that spoke to me recently as I was scuttling around getting ready for yet another spell on a chat-show sofa? More accurately, it was a memory of a voice in my head, and it told me that everything was OK and things were happening as they should. For a moment, the world had felt at peace. Where did it come from? Me, actually — the part of all of us that, in my case, caused me to stand in awe the first time I heard Thomas Tallis's Spem in alium, and the elation I felt on a walk one day last February, when the light of the setting sun turned a ploughed field into shocking pink; I believe it's what Abraham felt on the mountain and Einstein did when it turned out that E=mc2. It's that moment, that brief epiphany when the universe opens up and shows us something, and in that instant we get just a sense of an order greater than Heaven and, as yet at least, beyond the grasp of Stephen Hawking. It doesn't require worship, but, I think, rewards intelligence, observation and enquiring minds. I don't think I've found God, but I may have seen where gods come from."
