Now, if we take into consideration that this complicated organization developed among men who stood at the lowest known degree of development, and that it maintained itself in societies knowing no kind of authority besides the authority of public opinion, we at once see how deeply inrooted social instincts must have been in human nature, even at its lowest stages. A savage who is capable of living under such an organization, and of freely submitting to rules which continually clash with his personal desires, certainly is not a beast devoid of ethical principles and knowing no rein to its passions. But the fact becomes still more striking if we consider the immense antiquity of the clan organization. It is now known that the primitive Semites, the Greeks of Homer, the prehistoric Romans, the Germans of Tacitus, the early Celts and the early Slavonians, all have had their own period of clan organization, closely analogous to that of the Australians, the Red Indians, the Eskimos, and other inhabitants of the "savage girdle."(9) So we must admit that either the evolution of marriage laws went on on the same lines among all human races, or the rudiments of the clan rules were developed among some common ancestors of the Semites, the Aryans, the Polynesians, etc., before their differentiation into separate races took place, and that these rules were maintained, until now, among races long ago separated from the common stock. Both alternatives imply, however, an equally striking tenacity of the institution--such a tenacity that no assaults of the individual could break it down through the scores of thousands of years that it was in existence. The very persistence of the clan organization shows how utterly false it is to represent primitive mankind as a disorderly agglomeration of individuals, who only obey their individual passions, and take advantage of their personal force and cunningness against all other representatives of the species. Unbridled individualism is a modern growth, but it is not characteristic of primitive mankind.(10)
