“I’m not an atheist,” the great Harvard biologist E. O. Wilson said in 2015, “I’m a scientist. Atheism is the belief that there is no god, and you declare there is no god: ‘Come, my fellow atheists, let us march together and conquer those idiots who think there is a god—all these other tribes. We’re going to prevail.’ I would even say I’m agnostic because I’m a scientist.”
