In The New Republic Jerry A. Coyne coolly dismantles another instance of fuzzy theological thinking, this time Robert Wright's The Evolution of God (unread by me). According to this and other reviews of the book I've read, Wright argues not only that religion has become globally more beneficent and tolerant over historical time (a questionable enough claim), but also, without venturing to affirm that God does in fact exist, suggests in myriad hedging ways that it certainly looks as though he could exist, inasmuch as humanity is supposedly following the Golden Rule more often as the centuries pass.
Folks never tire, it seems, of trying to adduce evidence, whether scientific, historical, or sociological, for God's real existence. Kierkegaard--and many others besides I'm sure--had a lot to say about the folly of this undertaking. If you're going to believe, fine, but do so as a leap of faith, and stop saying that science suggests anything about the nature of God. There are a number of things in life that science per se can't help us with (such as how to live, what to do), but what it does do--explain the nature of material reality in testable fashion--it does very well indeed. There are things science can't explain yet, such as how the universe came to be, but science as of 1800 couldn't explain viruses either.
Not having read Wright's book, I obviously can't say much, but it seems to me that if humanity is becoming somewhat more peaceful and pro-social over time, it is less likely due to some kind of divinely inspired evolution than to the simple fact that the planet is getting a lot more crowded, and it's a lot harder than it ever was to swing one's elbows without hitting a neighbor. Folks could tolerate six-shooters on the frontier, but not nuclear weapons (or excessive carbon dioxide emissions) down the street. It's becoming more apparent as history passes that humanity resides not in a fortress, but in a boat. We can't allow ourselves to use up the fish or shoot up the hull.
Seeking to use science to buttress religion is precisely a lack of faith. I personally wouldn't care for any God who would allow (her)self to be captured in the nets of science.
