We seem here to be again at a loss. For behind the mere assertions of both parties there is a considerable amount of fact which seems to corroborate each of them. Spencer and Gillen do not give us bare statements. Such concrete and detailed accounts of beliefs as those quoted below[598] are very cogent. We see by them that Spencer and Gillen's assertion concerning the existence of reincarnation is the general expression of a series of positive facts; as there cannot be any doubt as to the authenticity of the latter, the general assertion of our authors is convincing! But if we inquire more precisely into the nature of this reincarnation we find certain "contradictions" and "inconsistencies" in these beliefs, and we can quite safely agree with Frhr. von Leonhardi that if we "take the expression exactly to the letter"[599] we are compelled to deny the existence of any ideas of reincarnation. The only objection is that any attempt to give "strict" or "exact" sense to aboriginal ideas is completely misplaced. The aborigines are not able to think exactly, and their beliefs do not possess any "exact meaning." And if an attempt be made to interpret them in this way, we shall always fail to understand them and to trace their social bearing. We must accept those beliefs as they stand in their quaint concreteness, full of contradictions and inconsistencies, and endeavour to mould our ideas upon the given folkloristic material, of which an adequate knowledge is indispensable for sociological purposes and gives us a very deep insight into the mechanism of different social groups. So, for instance, the aboriginal beliefs of reincarnation will be found to be of some importance as regards the idea of kinship. [598] Compare p. 216. [599] _Loc. cit._, ii. p. 56.
