+90+. The birthplace of this latter doctrine appears to have been the region in which Mazdaism arose, the country south of the Caspian Sea. Windischmann infers from Herodotus, iii, 62, that it appears as a Mazdean belief as early as the sixth century B.C.[187] This is doubtful, but it is reported as a current belief by Theopompus.[188] Its starting-point was doubtless the theory of reincarnation, which, we may suppose, the Iranian Aryans shared with their Indian brethren. Precisely what determined the Iranian movement toward this specific form of reincarnation we have no means of knowing. It may be due to the same genius for simple organization that led the Zoroastrians to discard the mass of the old gods and elevate Ahura Mazda to the chief place in the pantheon; their genius for practical social religious organization may have induced them to select human reincarnation as the most natural and the most effective morally, and to discard other forms as unworthy.[189] The dead man's own body would then be the natural dwelling place of his soul; but a refined body (as in 1 Cor. xv) might be regarded as better suited to the finer life of the future. Whatever the cause, they adopted this conception, and probably through their influence it passed to, or was formulated by, the Jews, among whom it appears in the second century B.C. (in the Book of Daniel).[190] In Daniel and 2 Maccabees resurrection is confined to the Jews; in Enoch it is sometimes similarly confined, sometimes apparently universal.[191] In the New Testament also the same diversity of statement appears; resurrection seems to be confined to believers in some passages[192] and to be universal in others.[193] In the former case it is regarded as a reward of piety and as a consequence of the intimate relation between the man and God or Christ; unbelievers then remain in hades, where they are punished. But universal resurrection was probably thought of as involved in the grandiose conceptions of a final judgment and a final moral restoration.[194] 5. POWERS OF THE SOUL +91+. Savage lore takes account of the powers of the separated soul only; the qualities and functions of the earthly incorporate soul are accepted as a part of the existing familiar order, and are not analyzed or discussed. It was different with the departed soul, which, because of its strangeness and mystery, was credited with extraordinary powers, and this part of savage science was gradually developed, through observation and inference, into an important system. In the search for causes, the Shade, its independent existence once established, came to be regarded as the agent in many procedures of which no probable account could otherwise be given.
