Ducking the G.Q.

Jerry A. Coyne wraps up his review of Robert Wright's The Evolution Of God:

When he finally comes to the big question--is there in fact a God who is pulling humanity toward morality?--he suddenly becomes humble and retiring. The existence of God, he plaintively concludes, is "a question that I'm unqualified to answer." What? With all this possible and purported evidence of divinity tugging at his sleeve, he still will not decide? Why doesn't Wright accept the thrust of his own arguments? Is he peddling a reassurance to others that does not work for himself?
