Spirits are not only powerful, however; they are also clairvoyant, prevoyant—they are acquainted with things that lie beyond our knowledge. More than that, they are benevolent or hostile; they are related to us in various social or antisocial ways. Here we have the elements of the notion of divine providence. The second semi-metaphysical idea, which lies in germ at the bottom of every religion, is, therefore, this of perspicacious spirits, of favouring or unfavouring deities, of providences. “This being is well or ill disposed toward me; he may work me good or harm.” Such is the first naïve formulation of the theory of divine providence. One must not expect to find, in the beginning, the notion of a general, directing intelligence, but simply that of a social tie between particular voluntary, well-disposed or ill-disposed beings. The notion of providence, like all other religious notions, was at first a superstition. A savage, on his way to some undertaking, meets a serpent and succeeds in his enterprise; it was the serpent that brought him luck: behold a providential accident! Gamblers at the present time are quite as superstitious. The fetich theory of providence still subsists, in the belief in medals, scapularies, and so forth.[38] Observation inevitably results in the perception of causal relations among phenomena; the trouble is, simply, that to the primitive mind every coincidence appears to be a cause; _post hoc, ergo propter hoc_. Any object that is a party to any such coincidence is a lucky object, good to have in one’s power, a portable providence, so to speak. Thus there arises the notion of a destiny, a bias in phenomena toward good or evil, which imposes itself upon the previously existing conception of nature as animated or peopled by spirits. The _post hoc, ergo propter hoc_—that is to say, the belief in the influence of phenomena immediately preceding or concomitant to the main event, and in the influence of a present action upon some future event—is the germ of superstitions both in regard to providence and to destiny. And out of the idea of destiny, of fortune, of necessity, grows in process of time the scientific notion of determinism and universal reciprocity.
