Religion has often unintentionally enabled scientific skepticism. The faithful will issue a challenge to science: Ha, you can’t explain the development of life, or the moral sense, or the nearly universal persistence of religion. To which the materialist responds: Can too. It is all biology and chemistry, thus disproving your God hypothesis. To this musty debate, Andrew Newberg, perhaps America’s leading expert on the neurological basis of religion, brings a fresh perspective. His new book, “How God Changes Your Brain,” co-authored with Mark Robert Waldman, summarizes several years of groundbreaking research on the biological basis of religious experience. And it offers plenty to challenge skeptics and believers alike.
