The only two systems in which the mysteries and the philosophies come together are Hinduism & Xtianity: there you get both Metaphysics and Cult (continuous with the primeval cults). That is why my first step was to be sure that one or other of these had the answer. For the reality can’t be one that appeals either only to savages or only to high brows. Real things aren’t like that (e.g. matter is the first most obvious thing you meet—milk, chocolates, apples, and also the object of quantum physics). There is no question of just a crowd of disconnected religions. The choice is between (a.) The materialist world picture: wh. I can’t believe, (b.) The real archaic primitive religions: wh. are not moral enough. (c.)The (claimed) fulfilment of these in Hinduism, (d.) The claimed fulfilment of these in Xtianity. But the weakness of Hinduism is that it doesn’t really join the two strands. Unredeemably savage religion goes on in the village; the Hermit philosophises in the forest: and neither really interferes with the other. It is only Xtianity wh. compels a high brow like me to partake in a ritual blood feast, and also compels a central African convert to attempt an enlightened universal code of ethics.
