already exists, but it cannot create it. Moreover, if, as the hypothesis of the animists supposes, the first sacred beings were really the souls of the dead and the first cult that of the ancestors, it should be found that the lower the societies examined are, the more the place given to this cult in the religious life. But it is rather the contrary which is true. The ancestral cult is not greatly developed, or even presented under a characteristic form, except in advanced societies like those of China, Egypt or the Greek and Latin cities; on the other hand, it is completely lacking in the Australian societies which, as we shall see, represent the lowest and simplest form of social organization which we know. It is true that funeral rites and rites of mourning are found there; but these practices do not constitute a cult, though this name has sometimes wrongfully been given them. In reality, a cult is not a simple group of ritual precautions which a man is held to take in certain circumstances; it is a system of diverse rites, festivals and ceremonies which _all have this characteristic, that they reappear periodically_. They fulfil the need which the believer feels of strengthening and reaffirming, at regular intervals of time, the bond which unites him to the sacred beings upon which he depends. That is why one speaks of marriage rites but not of a marriage cult, of rites of birth but not of a cult of the new-born child; it is because the events on the occasion of which these rites take place imply no periodicity. In the same way, there is no cult of the ancestors except when sacrifices are made on the tombs from time to time, when libations are poured there on certain more or less specific dates, or when festivals are regularly celebrated in honour of the dead. But the Australian has no relations of this sort with his dead. It is true that he must bury their remains according to a ritual, mourn for them during a prescribed length of time and in a prescribed manner, and revenge them if there is occasion to.[119] But when he has once accomplished these pious tasks, when the bones are once dry and the period of mourning is once accomplished, then all is said and done, and the survivors have no more duties towards their relatives who exist no longer. It is true that there is a way in which the dead continue to hold a place in the lives of their kindred, even after the mourning is finished. It is sometimes the case that their hair or certain of their bones are kept, because of special virtues which are attached to them.[120] But by that time they have ceased to exist as persons, and have fallen to the rank of anonymous and impersonal charms. In this condition they are the object of no cult; they serve only for magical purposes.
