We have been concerned to isolate four main conceptions of the philosophy of religion that have appeared in the history of Western thought, and to analyse their respective logical anatomies. Each type represents an original and thorough-going attempt to reconcile the demands of philosophical reason with the demands of that which is in some way "beyond" reason — the "divine", the "numinous", the 'supernatural". Each type exhibits its own peculiar understanding of what philosophy is, on the one hand, and what religion is on the other. Each has its own philosophical and religious benefits and attractions and its own equal and opposite difficulties and drawbacks: in the philosophy of religion, as in life, you pay a price for every advantage gained.
