But there is another class of words differing somewhat from those we have named, such words, as day, night, spring, winter, dawn and twilight; these lack the individuality and tangibleness of the others; and when we say “day approaches, night comes,” we attribute acts to things which are not agents, we affirm propositions, which, logically analysed, have no properly defined subjects. Semi-tangible names, such as sky, earth, belong to the same category. When we say “the earth nourishes man,” we do not allude to any well defined portion of the soil, we take the earth as a whole; and the sky is not only the small portion of the horizon grasped by our eyes, our imagination conceives objects not within the ken of our senses, but inasmuch as we look upon the earth or sky as a whole, see in it a power or an ideal, we make of it, involuntarily, an individuality. Now these words had certain terminations affixed to them indicating what we call gender, and became masculine or feminine, the neuter gender at that time did not enter into the language, until thought becoming more lucid perceived it in nature. What was the result? That it was impossible to speak of morning or night, of spring or winter, of dawn or twilight, of sky and earth, without clothing them not only with active and individual characteristics, but with personal and sexual attributes; hence all the objects of discourse as used by the founders of language became necessarily so many actors, as men and women act; and thought, when once launched in this direction, being irresistibly attracted by the tendency towards analogy and metaphor, overspread the whole world of human experience with this method of representation. What is called animism, anthropomorphism, and personification, have therefore their source in this inevitable dynamic stage, as Max Müller calls it, of thought and language, in which the psychological necessity of representing the external objects as resembling themselves operated on our ancestors. This necessity might have been named subjectivism had it not received more specific terms such as _animism_, which consists in conceiving of inanimate objects as animate; _anthropomorphism_, conceiving objects as men, and _personification_, conceiving objects as persons. As soon as this new mental act was performed, a new world was called into existence, a world of names, or as we now call it, the world of myths.
