+430+. Objections may be raised to all these theories. It is doubtful whether a scarcity of women existed in early times; and supposing that there were not women enough in a clan for the men of the clan, this would not stand in the way of men's taking as wives their clan women.[782] The assumption of primitive sexual promiscuity, likewise, cannot be said to be distinctly borne out by known facts.[783] Morgan's theory, however, is not dependent on this assumption--it need only suppose repugnance to the marriage of blood relations. Such repugnance granted, the main objection to the theory rests on the difficulty of supposing savages capable of originating so thoughtful and elastic a scheme as the exogamous system. This is a point on which it is not possible to speak positively. The lowest tribes have produced languages of wonderfully intricate and delicate construction, and, supposing the process of constructing marriage regulations to have gone on during a very long period, modifications introduced from time to time, to meet conditions felt to be important, might conceivably result in such exogamous systems as are now found. +431+. As to absence of sexual attraction between persons brought up together,[784] this seems to be a result rather than a cause of the prohibition of sexual relations between certain classes of persons. The argument from habits of the lower animals is indefinite--no general habit has been proven. In orgies in India and elsewhere no repulsion appears between persons of the same family. In the ancient world marriage between such persons was legal and not uncommon. +432+. The human horde, with its jealous patriarch, appears to be a creation of the scientific imagination. It, again, was derived by its author from the procedure of certain beast-herds in which the strongest male drives away his rivals. It is supposed, however, that in the human horde the young men, having found wives, are allowed to come back bringing their wives with them, and these last the patriarch is supposed not to appropriate. The theory is supported by no facts of actual usage. +433+. The supposition that the young men of a clan or tribe go off to seek food, and thus found a new clan, has more in its favor. Being compelled to seek wives in their new surroundings, they might thus initiate a habit of outside marriage that would in time become general usage and therefore sacred. Secession from tribes does occur, and may have been frequent in prehistoric times, but concerning these times we have little or no information. It may be said that movements of this sort would furnish a more probable starting-point for savage customs than the ideas and schemes mentioned above.
