From the end of The Whole Shebang:
"More appropriate, I should think, is the view that God created the universe out of an interest in spontaneous creativity - that he wanted nature to produce surprises, phenomena that he himself could not have foreseen. What would such a creative universe be like? Well, it would for one thing be impossible to predict in detail. And this seems to be the case with the universe we inhabit. The information theorists find that even if the entire universe were a computer, or could be converted into a computer of the maximum theoretically possible capability, that computer would be incapable of predicting all future phenomena. Further, a creative universe should give rise to agencies that are themselves creative, which is to say unpredictable. There is in our universe such an agency, spectacularly successful at reversing the dreary slide of entropy and making surprising things happen. We call it life. It would be suitable if this agency were to inquire into the workings of the universe, winnowing out the predictable from the unpredictable and inventing theories to account for the difference. And that is what intelligence does. Better still if thinking creatures were to perceive that they are all in the same boat - 'Poor, benighted members of the same ship's company,' in Adlai Stevenson's phrase - and hence treat one another kindly and assert that God is love. And so we do, though not often enough. ...
"Whether he left or was ever here I do not know, and don't believe we shall ever know. But one can learn to live with ambiguity - that much is requisite to the seeking spirit - and with the silence of the stars. All who genuinely seek to learn, whether atheist or believe, scientist or mystic, are united in having not a faith but faith itself. Its token is reverence, its habit to respect the eloquence of silence. For God's hand may be a human hand, if you reach out in loving kindness, and God's voice your voice, if you but speak the truth."
