Their superstitions are groveling and mean; and did this happen among rude nations alone, we could not sufficiently admire the effects of politeness; but it is a subject on which few nations are entitled to censure their neighbours. When we have considered the superstitions of one people, we find little variety in those of another. They are but a repetition of similar weaknesses and absurdities, derived from a common source, a perplexed apprehension of invisible agents, that are supposed to guide all precarious events to which human foresight cannot extend. In what depends on the known or the regular course of nature, the mind trusts to itself; but in strange and uncommon situations, it is the dupe of its own perplexity, and, instead of relying on its prudence or courage, has recourse to divination, and a variety of observances, that, for being irrational, are always the more revered. Superstition being founded in doubts and anxiety, is fostered by ignorance and mystery. Its maxims, in the mean time, are not always confounded with those of common life; nor does its weakness or folly always prevent the watchfulness, penetration, and courage, men are accustomed to employ in the management of common affairs. A Roman consulting futurity by the pecking of birds, or a king of Sparta inspecting the entrails of a beast, Mithridates consulting his women on the interpretation of his dreams, are examples sufficient to prove, that a childish imbecility on this subject is consistent with the greatest military and political conduct. Confidence in the effect of charms is not peculiar to any age or nation. Few, even of the accomplished Greeks and Romans, were able to shake off this weakness. In their case, it was not removed by the highest measures of civilization. It has yielded only to the light of true religion, or to the study of nature, by which we are led to substitute a wise providence operating by physical causes, in the place of phantoms that terrify or amuse the ignorant.
