In the case of savage and primitive man the inward image of the fetish without its bodily presence is, owing to the process already described, not merely valid as a real entity, but it becomes a mysterious apparition in the sphere of fancy, in a way analogous to our belief in the reality of things seen in a dream or in moments of hallucination. This appears in the history of all peoples past and present, whence it is certain that primitive man not only formed personifications of external objects and of his own emotions, but also of their images, as they were retained in his memory. In both cases the sequence of the three elements of apprehension, the phenomenon, subject, and cause, is due to the same unique faculty; in a word, the inward perception is identical in its genesis and laws with that which is external.
These are not the only results which follow from the exercise of this faculty. By the spontaneous classifying action of our intelligence we rise from the perception of special and individual objects and phenomena to their various types, and hence to an inward and ideal world of specific representations, as if these were causative powers, informing the multitude of analogous and similar phenomena in which they are manifested. These specific types, which are more strongly present to the fancy in the primitive exercise of the intelligence, also become personified, and they generate what is called polytheism in all its forms, varying according to the races, times, places, and respective conditions of morality and civilization in which they are found.
The same psychical faculty and the same elements are necessary for the personification of such types or idols. The three elements appear in their proper sequence even in the amorphous phantasms which these types first shadow forth, and which are subsequently perfected and embodied in human form. For the consciousness of the external form always exists in the first vague and nebulous conception of the phantasm which gradually appears and formulates itself in the vivid imagination; and hence follows the phenomenal vest, which, as usual, generates the corresponding subject, informed with a causative power. This process clearly shows, and in fact constitutes, the essence of myth.
