The origin of many notions touching a future state, found in literature, is to be traced to those rambling thoughts and poetic reveries with which even the most philosophical minds, in certain moods, indulge themselves. For example, Sir Isaac Newton "doubts whether there be not superior intelligencies who, subject to the Supreme, oversee and control the revolutions of the heavenly bodies." And Goethe, filled with sorrow by the death of Wieland, musing on the fate of his departed friend, solemnly surmised that he had become the soul of a world in some far realm of space. The same mental exercises which supply the barbarian superstitions reappear in disciplined minds, on a higher plane and in more refined forms. Culture and science do not deliver us from all illusion and secure us sober views conformed to fact. Still, what we think amid the solid realities of waking life, fancy in her sleep disjointedly reverberates from hollow fields of dream. The metaphysician or theologian, instead of resting contented with mere snatches and glimpses, sets himself deliberately to reason out a complete theory. In these elaborate efforts many an opinion and metaphor, plausible or absurd, sweet or direful, is born and takes its place. There is in the human mind a natural passion for congruity and completeness, a passion extremely fertile in complementary products. For example, the early Jewish notion of literally sitting down at table with Abraham and Isaac and Jacob, in the resurrection, was gradually developed by accretion of assisting particulars into all the details of a consummate banquet, at which Leviathan was to be the fish, Behemoth the roast, and so on.4 In the construction of doctrines or of discourses, one thought suggests, one premise or conclusion necessitates, another. This genetic application is sometimes plainly to be seen even in parts of incoherent schemes. For instance, the conception that man has returned into this life from anterior experiences of it is met by the opposing fact that he does not remember any preceding career. The explanatory idea is at once hit upon of a fountain of oblivion a river Lethe from which the disembodied soul drinks ere it reappears. Once establish in the popular imagination the conception of the Olympian synod of gods, and a thousand dramatic tales of action and adventure, appropriate to the characters of the divine personages, will inevitably follow.
