I find atheism extremely puzzling, like persistent attempts to square the circle or construct a perpetual motion machine.
To me it seems that our way of understanding the world will be usable—will actually function as an understanding—only if it is coherent, hierarchical and ethically directed. “Coherent” seems self-explanatory. “Hierarchical” means we must be able to distinguish principles that are more and less fundamental. “Ethically directed” means that our understanding must advise us what to do. There must be something about the world that makes things worth doing or not worth doing.
