SURVEYING the thought of mankind upon the subject of a future life, as thus far examined, one can hardly fail to be struck by the multitudinous variety of opinions and pictures it presents. Whence and how arose this heterogeneous mass of notions? In consequence of the endowments with which God has created man, the doctrine of a future life arises as a normal fact in the development of his experience. But the forms and accompaniments of the doctrine, the immense diversity of dress and colors it appears in, are subject to all the laws and accidents that mould and clothe the products within any other department of thought and literature. We must refer the ethnic conceptions of a future state to the same sources to which other portions of poetry and philosophy are referred, namely, to the action of sentiment, fancy, and reason, first; then to the further action, reaction, and interaction of the pictures, dogmas, and reasonings of authoritative poets, priests, and philosophers on one side, and of the feeling, faith, and thought of credulous multitudes and docile pupils on the other. In the light of these great centres of intellectual activity, parents of intellectual products, there is nothing pertaining to the subject before us, however curious, which may not be intelligibly explained, seen naturally to spring out of certain conditions of man's mind and experience as related with the life of society and the phenomena of the world. So far as the views of the future life set forth in the religions of the ancient nations constitute systematically developed and arranged schemes of doctrine and symbol, the origin of them therefore needs no further explanation than is furnished by a contemplation of the regulated exercise of the speculative and imaginative faculties. But so far as those representations contain unique, grotesque, isolated particulars, their production is accounted for by this general law: In the early stages of human culture, when the natural sensibilities are intensely preponderant in power, and the critical judgment is in abeyance, whatever strongly moves the soul causes a poetical secretion on the part of the imagination.1 Thus the rainbow is personified; a waterfall is supposed to be haunted by spiritual beings; a volcano with fiery crater is seen as a Cyclops with one flaming eye in the centre of his forehead. This law holds not only in relation to impressive objects or appearances in nature, but also in relation to occurrences, traditions, usages. In this way innumerable myths arise, explanatory or amplifying thoughts secreted by the stimulated imagination and then narrated as events. Sometimes these tales are given and received in good faith for truth, as Grote abundantly proves in his volume on Legendary Greece; sometimes they are clearly the gleeful play of the fancy, as when it is said that the hated infant Herakles having been put to Hera's breast as she lay asleep in heaven, she, upon waking,
