referred to as a sad but instructive monument of its influence. IV The consideration of the effects of a prepossession in favor of a belief in spirit-agency leads naturally to a consideration of the origin of the belief. This tendency to believe in the return to earth of the spirits of the departed, is probably to be viewed as a form of expression of the primitive animism that dominates savage philosophy, that pervades the historical development of religion and of science, and that crops out in various ways throughout all grades of civilization and all levels of society. Combined with it is an equally fundamental love for the marvelous, and a more or less suppressed belief in the significance of the obscure, the mysterious, the occult. These belief-tendencies, accordingly, have an anthropological significance and an historical continuity which Mr. Lang thus presents: "These instances prove that, from the Australian blacks in the Bush, who hear raps when the spirits come, to ancient Egypt, and thence to Greece, and last, in our own time, and in a London suburb, similar experiences real or imaginary are explained by the same hypothesis. No 'survival' can be more odd and striking, none more illustrative of the permanence, in human nature, of certain elements. To examine these psychological curiosities may, or may not, be 'useful,' but, at the lowest, the study may rank as a branch of mythology or folk-lore." Mr. Tylor fully concords with this view: "The received spiritualistic theory," he says, "belongs to the philosophy of savages.... Suppose a wild North American Indian looking on at a spirit-séance in London. As to the presence of disembodied spirits, manifesting themselves by raps, noises, voices, and other physical actions, the savage would be perfectly at home in the proceedings; for such things are part and parcel of his recognized system of nature." Mr. Podmore's comment upon the spiritualistic hypothesis expresses a kindred thought. "As the peasant referred the movement of the steam-engine to the only motive force with which he was acquainted, and supposed that there were horses inside, so the spiritualists, recognizing, as they thought, in the phenomena the manifestations of will and intelligence not apparently those of any person visibly present, invoked the agency of the spirits of the dead. We can hardly call this belief an hypothesis or an explanation; it seems indeed at its outset to have been little more than the instinctive utterance of primitive animism."
