But whence arises the necessity for craft and whence the craft? The faculty of invention implies skill. Skill successfully to play upon the instincts of humanity can only be acquired through the medium of like instincts, and although the skill be empirical, the play must be natural. Craft alone will not suffice to satisfy the desire; the hook must be baited with some small element of truth before the most credulous will seize it. If religious beliefs are the fruits of invention, how shall we account for the strange coincidences of thought and worship which prevail throughout all myths and cults? Why is it that all men of every age, in conditions diverse, and in countries widely sundered, are found searching out the same essential facts? All worship; nearly all have their creation-myth, their flood-myth, their theory of origin, of distribution from primitive centres, and of a future state. In this regard as in many another, civilization is but an evolution of savagism; for almost every principle of modern philosophy there may be found in primitive times its parallel.
The nature and order of supernatural conceptions are essentially as follows: The first and rudest form of belief is Fetichism, which invests every phenomenon with an independent personality. In the sunshine, fire, and water, in the wind and rock and stream, in every animal, bird, and plant, there is a separate deity; for every effect there is a cause. Even Kepler, whose intellect could track the planets in their orbits, must needs assume a guiding spirit for every world. It is impossible for the mind to conceive of self-creative or self-existent forces.
In time the personalities of the fetich-worshiper become to some extent generalized. Homogeneous appearances are grouped into classes, and each class referred to a separate deity, and hence Polytheism. Pantheism then comes in and makes all created substance one with the creator; nature and the universe are God. From the impersonating of the forces of nature to the creation of imaginary deities there is but a step. Every virtue and vice, every good and evil becomes a personality, under the direct governance of which lie certain passions and events; and thus in place of one god for many individuals, each individual may have a multitude of his own personal gods. The theogony of Hesiod was but a system of materialized love and hate; while, on the other hand, the gods of Homer, although personating human passions, were likewise endowed with moral perceptions. In them the blind forces of nature are lighted up into a human-divine intelligence.
