The development of the family, then, is founded on the continual contraction of the circle, originally comprising the whole tribe, within which marital intercourse between both sexes was general. By the continual, exclusion, first of near, then of ever remoter relatives, including finally even those who were simply related legally, all group marriage becomes practically impossible. At last only one couple, temporarily and loosely united, remains; that molecule, the dissolution of which absolutely puts an end to marriage. Even from this we may infer how little the sexual love of the individual in the modern sense of the word had to do with the origin of monogamy. The practice of all nations of that stage still more proves this. While in the previous form of the family the men were never embarrassed for women, but rather had more than enough of them, women now became scarce and were sought after. With the pairing family, therefore, the abduction and barter of women began--widespread symptoms, and nothing but that, of a new and much more profound change. The pedantic Scot, McLennan, however, transmuted these symptoms, mere methods of obtaining women, into separate classes of the family under the head of "marriage by capture" and "marriage by barter." Moreover among American Indians and other nations in the same stage, the marriage agreement is not the business of the parties most concerned, who often are not even asked, but of their mothers. Frequently two persons entirely unknown to one another are thus engaged to be married and receive no information of the closing of the bargain, until the time for the marriage ceremony approaches. Before the wedding, the bridegroom brings gifts to the maternal relatives of the bride (not to her father or his relatives) as an equivalent for ceding the girl to him. Either of the married parties may dissolve the marriage at will. But among many tribes, as, e. g., the Iroquois, public opinion has gradually become averse to such separations. In case of domestic differences the gentile relatives of both parties endeavor to bring about a reconciliation, and not until they are unsuccessful a separation takes place. In this case the woman keeps the children, and both parties are free to marry again.
