It has been shown how the doctrine of souls was developed according to the anthropological theory. The hypothesis as to how souls of the dead were later elevated to the rank of gods, or supplied models after which such gods might be inventively fashioned, will be criticised in a later chapter. Here it must suffice to say that the conception of a separable surviving soul of a dead man was not only not essential to the savage's idea of his supreme god, as it seems to me, but would have been wholly inconsistent with that conception. There exist, however, numerous forms of savage religion in addition to the creed in a Supreme Being, and these contribute their streams to the ocean of faith. Thus among the kinds of belief which served in the development of Polytheism, was Fetishism, itself an adaptation and extension of the idea of separable souls. In this regard, like ancestor-worship, it differs from the belief in a Supreme Being, which, as we shall try to demonstrate, is not derived from the theory of ghosts or souls at all. _Fetish_ (_fétiche_) seems to come from Portuguese _feitiço_, a talisman or amulet, applied by the Portuguese to various material objects regarded by the negroes of the west coast with more or less of religious reverence. These objects may be held sacred in some degree for a number of incongruous reasons. They may be tokens, or may be of value in sympathetic magic, or merely _odd_, and therefore probably endowed with unknown mystic qualities. Or they may have been pointed out in a dream, or met in a lucky hour and associated with good fortune, or they may (like a tree with an unexplained stir in its branches, as reported by Kohl) have seemed to show signs of life by spontaneous movements; in fact, a thing may be what Europeans call a fetish for scores of reasons. For our present purpose, as Mr. Tylor says, 'to class an object as a fetish demands explicit statement that a spirit is considered as embodied in it, or acting through it, or communicating by it, or, at least, that the people it belongs to do habitually think this of such objects; or it must be shown that the object is treated as having personal consciousness or power, is talked with, worshipped...' and so forth. The in-dwelling spirit may be human, as when a fetish is made out of a friend's skull, the spirit in which may even be asked for oracles, like the Head of Bran in Welsh legend.
