What your brain looks like on faith

Sam Harris is best known for his barn-burning 2004 attack on religion, The End of Faith, which spent 33 weeks on the New York Times best-seller List. The book's sequel, Letter to a Christian Nation also came out in editions totalling hundreds of thousands. Last Monday, however, the combative Californian produced a shorter (seven pages) and seemingly calmer publication that will be a hit if it reaches 10,000 readers: "Functional Neuroimaging of Belief, Disbelief and Uncertainty." It appears in the respected journal Annals of Neurology. And Harris, 40, claims it has little if any connection to his two popular books. Believers, however, may draw their own conclusions -- and may want to read his subsequent neurological studies even more carefully.
