Students of the primitive history of mankind tell of the enormous part played by animal tales, myths and cults. Sometimes a mystery is made out of this historical fact, as if it indicated that primitive man was moved by a different psychology from that which now animates humanity. But the explanation is, I think, simple. Until agriculture and the higher industrial arts were developed, long periods of empty leisure alternated with comparatively short periods of energy put forth to secure food or safety from attack. Because of our own habits, we tend to think of people as busy or occupied, if not with doing at least with thinking and planning. But then men were busy only when engaged in the hunt or fishing or fighting expedition. Yet the mind when awake must have some filling; it cannot remain literally vacant because the body is idle. And what thoughts should crowd into the human mind except experiences with animals, experiences transformed under the influence of dramatic interest to make more vivid and coherent the events typical of the chase? As men in fancy dramatically re-lived the interesting parts of their actual lives, animals inevitably became themselves dramatized. They were true _dramatis personæ_ and as such assumed the traits of persons. They too had desires, hopes and fears, a life of affections, loves and hates, triumphs and defeats. Moreover, since they were essential to the support of the community, their activities and sufferings made them, in the imagination which dramatically revived the past, true sharers in the life of the community. Although they were hunted, yet they permitted themselves after all to be caught, and hence they were friends and allies. They devoted themselves, quite literally, to the sustenance and well-being of the community group to which they belonged. Thus were produced not merely the multitude of tales and legends dwelling affectionately upon the activities and features of animals, but also those elaborate rites and cults which made animals ancestors, heroes, tribal figure-heads and divinities.
