"God should be flattered: unlike most of those clamoring for his attention, Hitchens treats him like an adult."
The above quote is from the New York Times Book Review and appears on the cover of my edition. I find it to be an excellent summary of the book, and of Hitchens's work in general. He treats God like any other human adult, holding him responsible for the actions attributed to him, and not letting God's celebrity status get in the way of justice.
My complaint of this book is the same as my complaint of pre-sober Hitchens in general. He has a lot of zingers and truly quotable lines, but they're buried under a meandering and unstructured argumentation. The book is divided into chapters, but there's no build-up or progression. It's more like Hitchens merely writes in the train of thought and then publishes, without regard for editing.
I also didn't like the lack of notation. He does have end-notes, but they aren't marked in the text and mostly only provide citations for the passages he quotes. Any "facts" that he writes aren't sourced, so it's often difficult to check their veracity. For example, on page 110 of my edition, he write: "One recalls a governor of Texas who, asked if the Bible should also be taught in Spanish, replied that 'if English was good enough for Jesus, then it's good enough for me.'" Unfortunately, no details are provided about this incident that might help the interested look it up. No name, no year, nothing except the location. It seems plausible that it's true, but I have no way of verifying it.
I'm being harsh on the book, but I did enjoy it. Hitchens is an excellent writer - funny, interesting, and he certainly keeps the pace moving. So this is a fine book to read while travelling or sitting by the pool. What it isn't is a resource or an argument. It's the fluff of the atheist library.
