The advice not to judge a book by its cover proves wise in the case of Alex Rosenberg’s latest tome. A fetching title and subtitle, which seem to fly out of the page from a Big-Bangish burst of white over the background of a colorful deep-space image, promise hours of thoughtful and imaginative reading about how freethinkers can enjoy life without resort to nonsense. It’s a beautiful, exciting cover, for what turns out to be a rather dull and overall underwhelming book. The book starts strong, by boldly stating its goal, namely answering the “unavoidable questions” in life. It also demarcates its audience: “This is a book for atheists,” we are told, for “people who are comfortable with the truth about reality.” It is certainly not for “people who believe in religion,” not even for “just doubters and agnostics” that are still undecided. No. It’s solely for those who “have moved past that point” and know for certain that “belief in God is on par with belief in Santa Claus.”
