The main objection to this third theory of Frazer’s is the same which has already been advanced against his second, sociological theory. The Aruntas seem to be far removed from the beginnings of totemism. Their denial of fatherhood does not apparently rest upon primitive ignorance; in many cases they even have paternal inheritance. They seem to have sacrificed fatherhood to a kind of a speculation which strives to honour the ancestral spirits[168]. Though they raise the myth of immaculate conception through a spirit to a general theory of conception, we cannot for that reason credit them with ignorance as to the conditions of procreation any more than we could the old races who lived during the rise of the Christian myths. Another psychological theory of the origin of totemism has been formulated by the Dutch writer, G. A. Wilcken. It establishes a connexion between totemism and the migration of souls. “The animal into which, according to general belief, the souls of the dead passed, became a blood relative, an ancestor, and was revered as such.” But the belief in the soul’s migration to animals is more readily derived from totemism than inversely[169]. Still another theory of totemism is advanced by the excellent American ethnologists, Franz Boas, Hill-Tout, and others. It is based on observations of totemic Indian tribes and asserts that the totem is originally the guardian spirit of an ancestor who has acquired it through a dream and handed it on to his descendants. We have already heard the difficulties which the derivation of totemism through inheritance from a single individual offers; besides, the Australian observations seem by no means to support the tracing back of the totem to the guardian spirit[170]. Two facts have become decisive for the last of the psychological theories as stated by Wundt; in the first place, that the original and most widely known totem object was an animal, and secondly, that the earliest totem animals corresponded to animals which had a soul[171]. Such animals as birds, snakes, lizards, mice are fitted by their extreme mobility, their flight through the air, and by other characteristics which arouse surprise and fear, to become the bearers of souls which leave their bodies. The totem animal is a descendant of the animal transformations of the spirit-soul. Thus with Wundt totemism is directly connected with the belief in souls or with animism.
