"[E]ven though the realms of religion and science in themselves are clearly marked off from each other" there are "strong reciprocal relationships and dependencies ⦠science without religion is lame, religion without science is blind ⦠a legitimate conflict between science and religion cannot exist." In Einstein's view, "neither the rule of human nor Divine Will exists as an independent cause of natural events. To be sure, the doctrine of a personal God interfering with natural events could never be refuted ⦠by science, for [it] can always take refuge in those domains in which scientific knowledge has not yet been able to set foot."
