The book is Outgrowing God: A Beginner’s Guide. Hart thinks Dawkins has finally found his authorial voice but you had better read the rest:
At last, Dawkins has found an authorial voice entirely adequate to his theme. And it is charming. Yes, of course, the confused and chaotic quality of his arguments remains a constant, and the basic conceptual mistakes have not altered appreciably since the earliest days of his polemics; but here it all comes across as the delightful babble of a toddler. “Do you believe in God?” he asks on the first page, tugging at your sleeve, eager to inform you of all the interesting things he has learned about religion this week. “Which god? Thousands of gods have been worshipped throughout the world, throughout history.” Do tell. And, in fact, tell he does, breathlessly emptying out his whole little hoard of knowledge about the local deities of ancient peoples. The sheer earnest impishness of his manner is almost enough to make you ignore his continued inability—despite decades of attempts by more refined logicians to explain his error to him—to distinguish between the mythic and devotional stories that peoples tell about their gods and the ontological and modal claims that the great monotheistic traditions of the “axial age” and after have made about God, or to grasp the qualitative conceptual gulf that separates them.
