It seems probable to us that the emblem has played a more important part than the name. In any case, the written sign still holds a more central place in the life of the clan to-day than does the spoken sign. Now the basis of an emblematic image can be found only in something susceptible of being represented by a design. On the other hand, these things had to be those with which the men of the clan were the most immediately and habitually coming in contact. Animals fulfilled this condition to a pre-eminent degree. For these nations of hunters and fishers, the animal constituted an essential element of the economic environment. In this connection plants had only a secondary place for they can hold only a secondary place as food as long as they are not cultivated. Moreover, the animal is more closely associated with the life of men than the plant is, if only because of the natural kinship uniting these two to each other. On the other hand, the sun, moon and stars are too far away, they give the effect of belonging to another world.[730] Also, as long as the constellations were not distinguished and classified, the starry vault did not offer a sufficient diversity of clearly differentiated things to be able to mark all the clans and sub-clans of a tribe; but, on the contrary, the variety of the flora, and especially of the fauna, was almost inexhaustible. Therefore celestial bodies, in spite of their brilliancy and the sharp impression they make upon the senses, were unfitted for the rôle of totems, while animals and plants seemed predestined to it. Ah observation of Strehlow even allows us to state precisely the way in which these emblems were probably chosen. He says that he has noticed that the totemic centres are generally situated near a mountain, spring or gorge where the animals serving as totems to the group gather in abundance, and he cites a certain number of examples of this fact.[731] Now these totemic centres are surely the consecrated places where the meetings of the clan are held. So it seems as though each group had taken as its insignia the animal or plant that was the commonest in the vicinity of the place where it had the habit of meeting.[732] VI This conception of totemism will give us the explanation of a very curious trait of human mentality which, even though more marked formerly than to-day, has not yet disappeared and which, in any case, has been of considerable importance in the history of human thought. It will furnish still another occasion for showing how logical evolution is closely connected with religious evolution and how it, like this latter, depends upon social conditions.[733]
