I finished this a few weeks ago, and have been trying to think of how to review it since. A good book can make you learn something about yourself. This one did that for me. I had the strange realization that while most of my childhood friends wanted to grow up to be famous celebrities or rock stars, I wanted to be Brilliant, with a capital B. The characters in this book are Brilliant, and so for me it read a little bit like a summer beach paperback about a rich debutante. Turns out I'm far from Brilliant, just bright (lowercase) with an aptitude for standardized tests. The story is about a university professor, who is being courted by the public and Harvard University due to his status as a newly christened intellectual celebrity, and a series of explorations about his personal relationships. It's a bit of a fictional peek inside the world of the intellectual elite. Along the way it explores a lot about the meaning of religion, which is of course very different from the meaning or existence of god.
This, as a sidebar, is my beef with the "atheist movement". The Dawkins crowd misses the importance of that difference.
Anyway, the author is clearly intelligent. It's the first book that I've ever read where I needed to consult a dictionary repeatedly. There are lots of big, intellectual words. Theodicy. Tautology. Disquisitions. There is a lot of philosophic arguments, that for the philosophy-naive is a fun re-exploration, almost made me feel like I was taking a college class on the philosophy of religion. There's higher math, game theory, religious history.
If you want a little of a mental workout, and a secular humanist viewpoint doesn't offend you, consider checking it out.
ShrinkRap just referenced a book that I'm going to order next.
