““How can men who disagree about what the world is for agree about any of the minutiae of daily conduct? The statement really means that it does not matter what a man believes so long as he does not take his beliefs seriously. Anyone can observe that this is the status to which religious belief has been reduced for many years. But suppose he does take his beliefs seriously? Then what he believes places a stamp upon his experience, and he belongs to a culture, which is a league founded on exclusive principles.””
