Although the difference presented by such phenomena and by death is that it is abiding, while they are temporary, to the barbaric mind the difference is in degree, and not in kind. True, the "other self" has left the body, and will never return to it; but it exists, for it appears in dreams and hallucinations, and therefore is believed to revisit its ancient haunts, as well as to tarry often near the exposed or buried body. The nebulous theories which identified the soul with breath, and shadow, and reflection, slowly condensed into theories of semi-substantiality still charged with ethereal conceptions, resulting in the curious amalgam which, in the minds of cultivated persons, whenever they strive to envisage the idea, represents the disembodied soul. Therefore, in vain may we seek for points of difference in our comparison of primitive ideas of the origin and nature of the soul with the later ideas. The copious literature to which these have given birth is represented in the bibliography appended to Mr. Alger's work on Theories of a Future Life, by 4977 books, exclusive of many published since his list was compiled. Save in refinement of detail such as a higher culture secures, what is there to choose between the four souls of the Hidatsa Indians, the two souls of the Gold Coast natives, and the tripartite division of man by Rabbis, Platonists, and Paulinists, which are but the savage other-self "writ large"? Their common source is in man's general animistic interpretation of Nature, which is a _vera causa_, superseding the need for the assumptions of which Mr. Wallace's is a type. As an excellent illustration of what is meant by animism, we may cite what Mr. Everard im Thurn has to say about the Indians of Guiana, who are, presumably, a good many steps removed from so-called "primitive" man. "The Indian does not see any sharp line of distinction such as we see between man and other animals, between one kind of animal and another, or between animals--man included--and inanimate objects. On the contrary, to the Indian all objects, animate and inanimate, seem exactly of the same nature, except that they differ in the accident of bodily form. Every object in the whole world is a being, consisting of a body and spirit, and differs from every other object in no respect except that of bodily form, and in the greater or lesser degree of brute power and brute cunning consequent on the difference of bodily form and bodily habits. Our next step, therefore, is to note that animals, other than men, and even inanimate objects, have spirits which differ not at all in kind from those of men."
