“Is this Tree of Life a God one could worship? Pray to? Fear? Probably not. But it did make the ivy twine and the sky so blue, so perhaps the song I love tells a truth after all. The Tree of Life is neither perfect nor infinite in space or time, but it is actual, and if it is not Anselm's "Being greater than which nothing can be conceived," it is surely a being that is greater than anything any of us will ever conceive of in detail worthy of its detail. Is something sacred? Yes, say I with Nietzsche. I could not pray to it, but I can stand in affirmation of its magnificence. This world is sacred.”

“If you can approach the world's complexities, both its glories and its horrors, with an attitude of humble curiosity, acknowledging that however deeply you have seen, you have only scratched the surface, you will find worlds within worlds, beauties you could not heretofore imagine, and your own mundane preoccupations will shrink to proper size, not all that important in the greater scheme of things.”

“One reader of an early draft of this chapter complained at this point, saying that by treating the hypothesis of God as just one more scientific hypothesis, to be evaluated by the standards of science in particular and rational thought in general, Dawkins and I are ignoring the very widespread claim by believers in God that their faith is quite beyond reason, not a matter to which such mundane methods of testing applies. It is not just unsympathetic, he claimed, but strictly unwarranted for me simply to assume that the scientific method continues to apply with full force in this domain of truth.Very well, let's consider the objection. I doubt that the defender of religion will find it attractive, once we explore it carefully.The philosopher Ronaldo de Souza once memorably described philosophical theology as "intellectual tennis without a net," and I readily allow that I have indeed been assuming without comment or question up to now that the net of rational judgement was up. But we can lower it if you really want to.It's your serve.Whatever you serve, suppose I return service rudely as follows: "What you say implies that God is a ham sandwich wrapped in tin foil. That's not much of a God to worship!". If you then volley back, demanding to know how I can logically justify my claim that your serve has such a preposterous implication, I will reply: "oh, do you want the net up for my returns, but not for your serves?Either way the net stays up, or it stays down. If the net is down there are no rules and anybody can say anything, a mug's game if there ever was one. I have been giving you the benefit of the assumption that you would not waste your own time or mine by playing with the net down.”

“If I know better than you know what I am up to, it is only because I spend more time with myself than you do.”

“My faith in the expertise of physicists like Richard Feynman, for instance, permits me to endorse—and, if it comes to it, bet heavily on the truth of—a proposition that I don't understand. So far, my faith is not unlike religious faith, but I am not in the slightest bit motivated to go to my death rather than recant the formulas of physics. Watch: E doesn't equal mc2, it doesn't, it doesn't! I was lying, so there!”

“But recently I have learned from discussions with a variety of scientists and other non-philosophers (e.g., the scientists participating with me in the Sean Carroll workshop on the future of naturalism) that they lean the other way: free will, in their view, is obviously incompatible with naturalism, with determinism, and very likely incoherent against any background, so they cheerfully insist that of course they don't have free will, couldn’t have free will, but so what? It has nothing to do with morality or the meaning of life. Their advice to me at the symposium was simple: recast my pressing question as whether naturalism (materialism, determinism, science...) has any implications for what we may call moral competence. For instance, does neuroscience show that we cannot be responsible for our choices, cannot justifiably be praised or blamed, rewarded or punished? Abandon the term 'free will' to the libertarians and other incompatibilists, who can pursue their fantasies untroubled. Note that this is not a dismissal of the important issues; it’s a proposal about which camp gets to use, and define, the term. I am beginning to appreciate the benefits of discarding the term 'free will' altogether, but that course too involves a lot of heavy lifting, if one is to avoid being misunderstood.”
