Science spotlights three dimensions of nature that point to God. The first is the fact that nature obeys laws. The second is the dimension of life, of intelligently organized and purpose-driven beings, which arose from matter. The third is the very existence of nature. But it is not science alone that has guided me. I have also been helped by a renewed study of the classical philosophical arguments.

The Koran calls for belief and consequent obedience. It is, surely, calculated to inspire fear, indeed abject terror, rather than love.

What would have to occur or to have occurred to constitute for you a disproof of the love of, or the existence of, God?

I am open to [the notion of theistic revelation], but not enthusiastic about potential revelation from God. On the positive side, for example, I am very much impressed with physicist Gerald Schroeder's comments on Genesis 1. That this biblical account might be scientifically accurate raises the possibility that it is revelation.

Pascal makes no attempt in this most famous argument to show that his Roman Catholicism is true or probably true. The reasons which he suggests for making the recommended bet on his particular faith are reasons in the sense of motives rather than reasons in the sense of grounds. Conceding, if only for the sake of the present argument, that we can have no knowledge here, Pascal tries to justify as prudent a policy of systematic self-persuasion, rather than to provide grounds for thinking that the beliefs recommended are actually true.

I'm thinking of a God very different from the God of the Christian and far and away from the God of Islam, because both are depicted as omnipotent Oriental despots, cosmic Saddam Husseins.

If it is to be established that there is a God, then we have to have good grounds for believing that this is indeed so. Until and unless some such grounds are produced we have literally no reason at all for believing; and in that situation the only reasonable posture must be that of either the negative atheist or the agnostic. So the onus of proof has to rest on the proposition of theism.
