I grew up in a faithful Methodist household in deep-red Texas during the George W. Bush years, when the political sway of evangelicals was at its zenith. At the same time, evangelists of a robust atheism—figures such as the biologist Richard Dawkins, the critic Christopher Hitchens, and the neuroscientist Sam Harris—toured the country offending salt-of-the-earth Americans with their contempt for religious belief. It was hard for me to ignore that a number of their assertions were clearly correct: Young-Earth creationism, for instance, instantly struck me as absurd when I first learned about it from a history teacher in my public junior-high school, who confidently told me that the world is only a few thousand years old.
That wasn’t what my family or church taught, but Christians who subscribed to those beliefs were suddenly ascendant, and their thinking colored the country’s religious landscape. Meanwhile, the New Atheists were making hay of the fact that such faithful misapprehensions about nature were easily disproved by scientific discovery. Though I continued to attend church as usual, I privately wondered whether the entire enterprise might be rooted in nothing more than a misunderstanding.
