To own the truth: I was a little afraid of reading Dawkin's "The God Delusion". I still hold some glimmer of faith in my agnostic soul. I secretly feared that reading a good, well-reasoned argument against the existence of god would snuff the frail thing out. But the bizarre thing is: his arguments are weak. Not all of them, of course. He has some very valid things to say about the false priveledge that religion holds in influencing politics, the veneration we give religious scholars, and the hateful role religion plays in history. I believe that organized religion is, for the most part, an evil institution. But his refutation against god is by arguing in the improbability of the existence of god. This argument absolutely cannot convince me.
As a physicist who is constantly in awe of the things I can't possibly understand, who is confronted with half a dozen equally probable but mutually exclusive "grand unified theories" of the universe and hardly any experimental means to judge between them, I cannot, in the depths of my soul, believe this argument. Dawkins ridicules the concept of miracles because they require that some deity change the immutable nature of stuff...such as making chemicals ignite at temperatures below their ignition temperatures, or modifying other "proven" physical properties. But he is discussing empirical physical properties, not fundamental ones. We have empirical evidence that water has a particular set freezing and boiling points. But, when you get to the world of the very very small: quantum mechanics small or even smaller (say, anything less than the Planck length - which we cannot measure, no matter how clever we are), or even very large, the strange thing is: things are mutable by nature. And they may choose improbable paths. Electrons can choose where they want to go, or they may simply tunnel through a solid object. Time and space can expand or contract. There may not be 3 spatial dimensions as we have always thought, but, if one form of string theory is right: 26. What happens in those other dimensions?
Interestingly, a probability calculation requires a set of assumptions and conditions. It isn't wrong to try to put this together as Dawkins does, but then he must also concede that the quality of the output is only as good as the quality of his input. Is it reasonable to accurately create the equation for the probability of god's existence when we lack enough evidence to calculate the probability of one theory of the universe's behavior over another? if god does exist, then he or she is certainly more complex and grand than any of these physical phenomena.
Dawkins goes on to discuss all of the scientists and educated people in the world who are Atheist, as though peer pressure would be enough to convince me that the improbability argument was on sound footing. What strikes me is this: if the every wise person in the world deemed the existence of god to be completely and utterly improbable, well, then I would believe in her/him even more because the god of improbability makes sense with everything I have learned about love.
Love itself is completely irrational. Mutual affection or tribal affiliation serves our own selfish purposes. But genuine love, altrusitic godlike love, short-circuits the most powerful instinct we have for survival. It is the irrational god who can actually love me. It is the improbable god who forms patterns and creates universes.
Of course, the damning religiousity that rules the world bears no resemblance to the god that I pray to.
