The connexion of Totemism with Exogamy (the custom of marrying outside the group or kin) Lang conceives of in this way. Adopting a suggestion of Darwin’s,[527] and the scheme of his cousin, J. J. Atkinson in _Primal Law_, that the primary human group consisted of a powerful male with one or more wives and their children, he argues that the jealousy of the head of this family imposed the rule—“No male to touch the females in my camp.” The sons, therefore, as they grew up, were driven out, and must find wives elsewhere. This was the beginning of Exogamy, and it may have preceded the rise of Totemism; but Totemism, once established, strengthened the custom of Exogamy by mysterious sanctions. As the Totem might not be eaten, or in any way used or touched, so a woman of the same Totem could not be married; and that not only within their immediate family-group, but not even by a male of any group having the same Totem. * * * * * In maintaining this hypothesis against those who would derive Totems from the names and traditions of individuals, Lang seems to me to lay too much stress upon the difficulty of establishing a tradition of descent amongst people who trace descent (as he would say) “on the spindle side.” If the tradition began from a woman (as it might do), there is no difficulty; and even if it began from a man, it is conceivable that his women-folk should adopt it. Moreover, in the opinion of both Westermarck and Frazer, it has not been shown that the reckoning of descent in the female line is original and universal. Still, the further we push back the origin of Totemism the more difficult it is to understand the growth of a tradition of the descent and inheritance of the name and personal qualities of an individual; and this difficulty is avoided by an hypothesis which derives Totemism from the animal- or plant-names of groups of men and women. That such names were conferred upon each group by others in the neighbourhood is a reasonable conjecture;[528] being the earliest names of groups they cannot be called nicknames; and the names of animals or plants need in no way have been offensive. It is still more reasonable to urge that, having been adopted by a group, the circumstances of their acquisition would, in a few generations, be forgotten, and that they would then become the ground of myths and mysterious totemic beliefs. But does any one think that it will now ever be possible to decide with confidence where, when, how or why the names were given at first? I do not. As to the origin of Exogamy, I cannot believe that the primitive human groups were such as Lang described; and, if not, some other origin of that custom must be sought. § 5. TOTEMISM AND MARRIAGE
