In more recent times, therefore, Frazer, whose great work, "Totemism and Exogamy," has assembled the richest collection of facts concerning totemic culture, has turned to an essentially different theory. He traces all forms of totemism back to conception totemism. Since the latter, as we have already stated, probably arose out of individual totemism, we are again confronted by an individualistic view, much as in the hypothesis of the origin from names. Frazer derives conception totemism from the dreams which mothers are supposed occasionally to have experienced before the birth of a child. The animal appearing in such a dream is thought to have become the totem or guardian animal of the child. But, though conception totemism, as well as sex totemism, may possibly have some connection with such phenomena--the fact that the animals here concerned are chiefly nocturnal animals suggests that such may be the case--totemism as a whole may, nevertheless, scarcely be derived from dreams. Still less can this hypothesis be harmonized with the fact that conception totemism is an anomaly. The ideas centred about it are but of rare occurrence within the system of totemic culture as a whole. Moreover, as Frazer also has assumed, they never appear except as an offshoot of individual totemism, and this in turn, when viewed in all its phases, cannot be regarded otherwise than as a product of tribal totemism. In its reference to the dream, however, this hypothesis may perhaps contain an element of truth, inasmuch as it involves ideas that obviously play an important rôle in totemism. This is shown particularly by reference to the totem animals that are found most commonly in Australia, and that suggest a relation between totemism and animistic ideas of the soul.
