We are playing a game of metaphysics, ontology, logic, epistemology, ethics, politics, aesthetics and phenomenology rolled into one. And here it is for the end result. There is no single universal category for the likes of evidence, existence, test and so on. That includes religion, philosophy and science. We are in practice play a limited game of cognitive, moral and cultural relativism and that applies to us both. I just know it is so both for you and me. In practice you have faith just like all other humans.
