The New Atheist types, like Dawkins, act as if science had revealed the world as a closed system. That simply is not what contemporary science is about. A lot of scientists are atheists, but they don’t talk about reality in the same way that Dawkins does. And they would not assume that there is a simple-as-that kind of response to everything in question. Certainly not on the grounds of anything that science has discovered in the last hundred years.
