We have clearly demonstrated the indisputable fact that the absolute condition of intrinsic animal perception, and consequently of the primary perception of man, was the animation and vivification of the things and phenomena perceived. This primary acquaintance with things depended on their spontaneous resolution into active and personal subjects. Nor could it be otherwise. Although the scientific idea or notion of objective reality in itself could not be grasped by simple animal intelligence, the impression of the thing perceived was necessarily that of a subjectivity resembling that of the observer, not indeed in outward form and figure but in intrinsic power, whatever might be the extrinsic form and figure of the object or phenomenon. The original condition of animals, and of man himself in his primordial life and consciousness, is and was the intrinsic personification of the things perceived: from this source the human intellect slowly and with difficulty attained to science, by virtue of that psychical reduplication which has been so often mentioned. The motive or subject of myth may be external, cosmic, or it may be internal, intellectual, and moral, but in each case the cause and faculty at work are the same. Just as the primary condition of observation, and consequently the motive principle of science, consists in the primitive exercise of the intelligence, which leads to empirical and rational knowledge, so myth and science have a common origin in the immediate transformation of natural objects and phenomena into living subjects, and they flow from the same deep source. The object in view is different, but their constructive faculty is the same, and they are, up to a certain point in their long historic course, evolved in the same way. Science, therefore, from one point of view, is the gradual exhaustion and dissolution of myth into the objects which are scientifically investigated, and this will appear more clearly in the sequel. The series of various phenomena, whether of light, of meteors, of water, of vegetable and animal forms, which were the first subjects of myths, became so interwoven as finally to be represented in an anthropomorphic personality, and were thus gradually lost and evaporated in the ideal symbol. As time went on, by the exercise of the intelligence, and by the aid of the observations and collateral experiments naturally connected with them, man ended where he had begun; released from myth, he only recognized the facts and laws of the world. This clearly shows, not only the formation of myths, but the process of evolution by which they pass into science, in which they find their termination.
