 Science and religion are closely interconnected in the scientific study of religion, which can be traced back to seventeenth-century natural histories of religion. Natural historians attempted to provide naturalistic explanations for human behavior and culture, including religion and morality. For example, Bernard Le Bovier de Fontenelle’s De l’Origine des Fables (1724) offered a causal account of belief in the supernatural. People often assert supernatural explanations when they lack an understanding of the natural causes underlying extraordinary events: “To the extent that one is more ignorant, or one has less experience, one sees more miracles” (1724 [1824: 295], my translation). Hume’s Natural History of Religion (1757) is perhaps the best-known philosophical example of a natural historical explanation of religious belief. It traces the origins of polytheism—which Hume thought was the earliest form of religious belief—to ignorance about natural causes combined with fear and apprehension about the environment. By deifying aspects of the environment, early humans tried to persuade or bribe the gods, thereby gaining a sense of control.
