David Hayward shared this older cartoon of his today:
The title seems to me precisely wrong. There is indeed a dividing line between those who see the world in terms of binary opposites, and those who see the world as rich, complex, deep, beautiful, and defying simple categories. But that line cuts through the whole of humanity, distinguishing between different sorts of religious believers, but also between different sorts of atheists, while placing some in those categories together on the same side of the dividing line.
So on this David Hayward seems to me to be wrong. His cartoon makes an important point. But it is about the fundamentalist mindset, and not about all religious mindsets.
