Thus, totemism is directly connected with the belief in souls--that is to say, with _animism_. It represents that branch of animism which exercised a long-continuing influence on the tribal organization as well as on the beliefs of peoples. But before turning to these final aspects of totemism and their further developments, it is necessary to consider another group of ideas which, in their beginnings, occupied an important place within the circle of totemic beliefs. The ideas to which I refer are those connected with the custom of _taboo_. 10. THE LAWS OF TABOO. It is a significant fact that 'totem' and 'taboo' are concepts for which our cultural languages possess no adequate words. Both these terms are taken from the languages of so-called natural peoples, 'totem' from an idiom of the North American Indians, and 'taboo' from the Polynesian languages. The word 'totem' is as yet relatively uncommon in literature, with the exception of books on ethnology and folk psychology; the word 'taboo,' on the other hand, is much in use. A thing is called taboo when it may not be touched, or when it must be avoided for some reason, whether because of its peculiar sanctity or contrariwise because its harmful influence renders it 'impure,' defiling every one who comes into contact with it. Thus, two opposing ideas are combined in the conception of taboo: the idea of the sacred as something to be avoided because of its sanctity, and that of the impure or loathsome, which must be avoided because of its repulsive or harmful nature. These ideas combine in the conception of _fear_. There is, indeed, one sort of fear which we call _awe_, and another termed _aversion_. Now, the history of taboo ideas leaves no doubt that in this case awe and aversion sprang from the same source. That which aroused aversion at a later age was in the totemic period chiefly an object of awe, or, at any rate, of fear--that is, of a feeling in which aversion and awe were still undifferentiated. That which is designated by the simplest word [_Scheu_] is also earliest in origin; awe [_Ehrfurcht_] and aversion [_Abscheu_] developed from fear [_Scheu_].
