Finally, the really original feature of these totems is that they are, in a sense, a sort of tribal totems. In fact, they result from men's representing the tribe as descended as a whole from one couple of mythical beings. Such a belief seems to demonstrate clearly that the tribal sentiment has acquired sufficient force to resist, at least to a considerable extent, the particularism of the clans. In regard to the distinct origins assigned to men and to women, it must be said that its cause is to be sought in the separate conditions in which the men and the women live.[550] It would be interesting to know how the sexual totems are related to the totems of the clans, according to the theory of the Australians, what relations there were between the two ancestors thus placed at the commencement of the tribe, and from which one each special clan is believed to be descended. But the ethnographical data at our present disposal do not allow us to resolve these questions. Moreover, however natural and even necessary it may appear to us, it is very possible that the natives never raised it. They do not feel the need of co-ordinating and systematizing their beliefs as strongly as we do.[551] CHAPTER V ORIGINS OF THESE BELIEFS _Critical Examination of Preceding Theories_ The beliefs which we have just summarized are manifestly of a religious nature, since they imply a division of things into sacred and profane. It is certain that there is no thought of spiritual beings, and in the course of our exposition we have not even had occasion to pronounce the words, spirits, genii or divine personalities. But if certain writers, of whom we shall have something more to say presently, have, for this reason, refused to regard totemism as a religion, it is because they have an inexact notion of what religious phenomena are.
