These facts necessarily lead to the question, are all men of one class, totem, and seniority, actual husbands of all women of the opposite class, different totem, and equivalent seniority? (Group Marriage). Or, if this is no longer the case, was it once the case? and are these sweeping uses of names which include our ‘father,’ ‘mother,’ ‘brother,’ ‘child,’ survivals of such a stage, called ‘Group Marriage’? This question is still undecided; good authorities take opposite views of the question, which has bred, in the past, much angry controversy. MR. MORGAN AND THE CLASS SYSTEM The arrangement by ‘classes,’ ‘the classificatory system,’ was first brought into scientific prominence by the late Mr. Lewis Morgan, an American gentleman affiliated to the Iroquois tribe, in his very original studies of the names for degrees of kinship.[3] A great deal may be said, and has been said, especially by Mr. McLennan and Dr. Westermarck, against Mr. Morgan’s ideas and methods, but his large and careful collection of facts is of high importance. On what he called ‘the Malayan system,’ one name denoting kin includes all my brothers, sisters, and cousins. Another name includes my father, mother, my uncles, aunts, and all the cousins of my father, mother, aunts, and uncles. The generation of my grandparents and their relations is included in a third name; a fourth covers my children and their cousins, and the grandchildren of my brothers and sisters, with their children, bear the same name, for me, as my own grandchildren. From the names Mr. Morgan inferred the existence of certain facts in the evolution of systems of kindred. Everybody of the same generation lived together, once, on his theory, in ‘communal marriage,’ brothers, sisters, and cousins. There was promiscuity between all men and women in the same generation. Of course this involves the converse of Mr. Atkinson’s Primal Law, as Mr. Atkinson observes in his eighth chapter. In place of the prohibition of brother and sister union being the earliest of prohibitions (as in Mr. Atkinson’s system), the rule that they must unite, caused, in Mr. Morgan’s opinion, the earliest form of the human family.
