"Felix qui potuit rerum cognoscere causas." CHAPTER VII. THE HISTORICAL EVOLUTION OF MYTH AND SCIENCE. In the foregoing pages we have reached the primordial fact of our psychical and physical nature, in which, as it appears to us, both myth and science have their origin. After first considering the animal kingdom as a whole, we have seen that the interaction between external phenomena and the consciousness of an organism results in the spontaneous vivification of the phenomenon in question, so that the origin of the mythical representation of nature is found in the innate faculty of animal perception. Nor could it be otherwise. The internal activity and intrinsic sense of conscious and deliberate life which inspires animals and men, while the latter are still ignorant of the rational order of things, is necessarily reflected both in the external objects of perception and in the internal emotions, as if they were operating causes independent of the will of the percipient. It is impossible for an animal, which is unable by voluntary observation to make, any analytic distinction between the subject and the object, and their respective effects, to consider such phenomena as mechanical entities, subject to necessary and eternal laws. The animal therefore accepts the idea suggested by his spontaneous and subjective nature, that these phenomena are alive. Grass, fruits, plants, water, the movement of material bodies, ordinary and extraordinary meteors, all are implicitly apprehended by him as subjects endowed with will and purpose after the manner of mankind. Nor can the living subjectivity of the phenomenon ever be gauged by the animal in whom the deliberate power of reflection is wanting. His life is consequently passed in a world of living subjects, not of phenomena and laws which mechanically act together; it is, so to speak, a permanent _metaphor_. Man himself, so far as his animal nature is concerned, acts in the same way, and although he subsequently attains to the exercise of reasoning powers in virtue of the psychical reduplication of himself, the primitive faculty persists, and hence comes the mythical creation of a peculiar world of conceptions which give rise to all superstitions, mythologies, and religions. This is also the process of science itself, as far as the classifying method and intrinsic logical form are concerned. The historical source of the two great streams of the intellect, the mythical and the scientific, is found in the primitive act of _entifying_ the phenomenon presented to the senses.
