It may be appropriate here, before leaving the subject of the Second Birth, to inquire how it has come about that this doctrine--so remote and metaphysical as it might appear--has been taken up and embodied in their creeds and rituals by quite PRIMITIVE people all over the world, to such a degree indeed that it has ultimately been adopted and built into the foundations of the latter and more intellectual religions, like Hinduism, Mithraism, and the Egyptian and Christian cults. I think the answer to this question must be found in the now-familiar fact that the earliest peoples felt themselves so much a part of Nature and the animal and vegetable world around them that (whenever they thought about these matters at all) they never for a moment doubted that the things which were happening all round them in the external world were also happening within themselves. They saw the Sun, overclouded and nigh to death in winter, come to its birth again each year; they saw the Vegetation shoot forth anew in spring--the revival of the spirit of the Earth; the endless breeding of the Animals, the strange transformations of Worms and Insects; the obviously new life taken on by boys and girls at puberty; the same at a later age when the novice was transformed into the medicine-man--the choupan into the angakok among the Esquimaux, the Dacotah youth into the wakan among the Red Indians; and they felt in their sub-conscious way the same everlasting forces of rebirth and transformation working within themselves. In some of the Greek Mysteries the newly admitted Initiates were fed for some time after on milk only "as though we were being born again." (See Sallustius, quoted by Gilbert Murray.) When sub-conscious knowledge began to glimmer into direct consciousness one of the first aspects (and no doubt one of the truest) under which people saw life was just thus: as a series of rebirths and transformations. (1) The most modern science, I need hardly say, in biology as well as in chemistry and the field of inorganic Nature, supports that view. The savage in earliest times FELT the truth of some things which we to-day are only beginning intellectually to perceive and analyze.
