+549+. A similar remark must be made in reference to theories based on the belief that the souls of the dead are incarnate in animals and plants. Such a belief is a natural outgrowth from the conception of the identity of nature of human beings and animals, and it occurs in so many parts of the world (Oceania, Africa, America) that it might naturally be regarded as having been at one time universal, though it is not now found everywhere. Reverence for an ancestor might be, and sometimes is, transferred to the object in which he is supposed to be incarnate; from this object a man holds himself to be descended, and he refrains from eating or injuring it.[908] This view, a combination of reverence for ancestors and reverence for animals and plants, thus supplies two features of totemistic organization, but proof is lacking that it is the basis of this organization. If it be the determining consideration in some cases, there are many cases in which its influence is not apparent. There are myths tracing the totemism of clans to ancestors having animal forms, but these myths are relatively late savage philosophical explanations of existing institutions. +550+. The relation of the individual patron and guardian to the clan totem has been variously defined. Such a patron, it is sometimes held (obtained by a dream or a vision), descends from the original possessor to his children (or, in a matrilineal system, to his sister's children), and thus becomes the patron (the totem) of a family or kin; and a larger group, formed by the union of several kins, may similarly have its protecting spirit. Cases in which descent is through the mother here make a difficulty--a man's guardian spirit would not then be inherited. Granting that the personal patron of a shaman or of an ordinary man may be inherited, such inheritance appears to be of rare occurrence, and there is no trustworthy evidence that it ever leads to the formation of a totemic clan. +551+. It is true there is a resemblance between a man's relation to his clan totem and his relation to his personal guardian--in both cases the sacred object is revered and spared. It is sometimes the case also (as, for example, among the Australian Arunta) that the totem comes through an individual (the mother) and is not transmissible, and yet endogamous clans arise by the union of persons having the same totem. But here the resemblance ceases--the Arunta child's totem is determined for him before his birth, but a man chooses his personal guardian for himself, and joins others having the same guardian, not in a clan but in a secret society. Furthermore, the institution of the personal guardian is very rare except in North America, and there flourishes in inverse proportion to the strength of clan life proper.
