The Natural History of Religion is a classic religious history essay by David Hume. In this essay, Hume offers a pioneering naturalist account of the causes, effects, and historical development of religious belief. Hume argues that a crude polytheism was the earliest religion of mankind and locates the origins of religion in emotion, particularly hope, fear, and the desire to control the future. He further argues that monotheism arises from competition between religions, as believers seek to distinguish their deities as superior to all rivals, magnifying those deities until they possess all perfections. Though an enlightened monotheism is more rationally defensible than a superstitious polytheism, in practice polytheism has many advantages. In particular, Hume argues, monotheistic religions tend to be more intolerant and hypocritical, result in greater intellectual absurdities, and foster socially undesirable "monkish virtues," such as mortification, abasement, and passive suffering. Hume concludes the "Natural History" on a note of characteristic skepticism: "The whole is a riddle, an aenigma, an inexplicable mystery. Doubt, uncertainty, suspence of judgment appear the only result of our most accurate scrutiny, concerning this subject. But such is the frailty of human reason, and such the irresistible contagion of opinion, that even this deliberate doubt could scarcely be upheld; did we not enlarge our view, and opposing one species of superstition to another, set them a quarrelling; while we ourselves, during their fury and contention, happily make our escape, into the calm, though obscure, regions of philosophy." "As every enquiry, which regards religion, is of the utmost importance, there are two questions in particular, which challenge our attention, to wit, that concerning its foundation in reason, and that concerning its origin in human nature. Happily, the first question, which is the most important, admits of the most obvious, at least, the clearest solution. The whole frame of nature bespeaks an intelligent author; and no rational enquirer can, after serious reflection, suspend his belief a moment with regard to the primary principles of genuine Theism and Religion."
