The investigations of Morgan bring, moreover, other interesting facts to light. Although the "pairing family" of the Iroquois starts in insolvable contradiction with the terms of consanguinity in use among them, it turns out that, as late as the first half of the 19th Century, there existed on the Sandwich Islands (Hawaii) a family-form that actually tallied with that which, among the Iroquois, existed in name only. But the system of consanguinity, in force in Hawaii, failed, in turn, to tally with the family-form actually in existence there. It referred to an older family-form, one still more primitive, but no longer extant. There, all the children of brothers and sisters, without exception, were "brothers" and "sisters." Accordingly, they were not considered the common children of their mothers and of the sisters of these, or of their fathers and of the brothers of these, but of all the brothers and sisters of their parents, without distinction. The Hawaiian system of consanguinity corresponded, accordingly, with a stage of development that was lower than the family-form still actually in existence. Hence transpires the curious fact that, in Hawaii, as with the Indians of North America, two distinct systems of consanguinity are, or rather, at a time, were in vogue, which no longer tallied with actual conditions, but were both overtaken by a higher state. On this head Morgan says: "The family represents an active principle. It is never stationary, but advances from a lower to a higher form as society advances from a lower to a higher condition, and finally passes out of one form into another of higher grade. Systems of consanguinity, on the contrary, are passive; recording the progress made by the family at long intervals apart, and only changing radically when the family has radically changed."

The theory, – even to-day generally considered conclusive, and which is stubbornly upheld as irrefutable by the representatives of the status quo– to the effect that the existing family-form has existed since time immemorial, and, lest the whole social fabric be put in jeopardy, must continue to exist forever, turned out, accordingly, after these discoveries of the investigators, to be wholly false and untenable. The form, under which the relations of the sexes appear and the situation of the family is raised, depends rather upon the social conditions, upon the manner in which man controls his subsistence. The form changes with the changed degree of culture at each given period.

The study of primitive history leaves now no room for doubt that, at the lowest grades of human development, the relation of the sexes is totally different from that of latter times, and that a state of things resulted therefrom, which, looked at with modern eyes, appears as monstrous, and as a sink of immorality. Nevertheless, as each social stage of human development has its own conditions of production, so likewise has each its own code of morals, which is but the reflection of the social condition. That is moral which is usage; and that, in turn, is usage which corresponds with the innermost being, i. e., the needs of a given period.

Morgan reaches the conclusion that, at the lower period of savagery, there was sexual intercourse between the several grades or generations, every woman belonging to every man, and every man to every woman, – in other words, promiscuity. All men live in polygamy and all women in polyandry. There is a general community of women and of men, but also a community of children, Strábo reports (sixty-six years before our reckoning) that, among the Arabians, brothers cohabited with sisters and with their own mother. On any route other than that of incest, the increase of population is nowhere possible, if, as alleged in the Bible also, descent from one couple is granted. The Bible itself contradicts itself on this delicate point. It is stated there that Cain, after he had murdered his brother Abel, took a wife of another people. Whence came that other people? The theory of promiscuity in primitive times, that is to say, that the horde was endogamous, that sexual intercourse was indiscriminate, is furthermore supported by the Hindoo myth, according to which Brahma married his own daughter Saravasti. The same myth turns up again among the Egyptians and the northern Edda. The Egyptian god Ammon was the spouse of his own mother, and boasted of it. Odin, according to the Edda, was the mate of his own daughter Frigga.² Morgan proceeds from the principle that, from the state of promiscuity, soon a higher form of sexual intercourse took shape. He designates this the consanguine family. Here the groups, that stand in sexual relation, are separated by grades or generations, so that grandfathers and grandmothers, within an age group, are husbands and wives. Their children, likewise, constitute a group of common couples; likewise the children of these, so soon as they have reached the requisite age. Accordingly, in contrast with the sex relations of the rawest period, in which promiscuity of sexes exists without distinction of age, now one generation is excluded from sexual intercourse with another. Sexual intercourse, however, exists between brothers and sisters, male and female cousins of the first, second and third remove. All of these together are brothers and sisters, but towards one another, they are all husbands and wives. This family-form corresponds with the system of consanguinity that still existed in Hawaii during the first part of the 19th Century, in name only, but no longer in fact. On the other hand, according to the American Indian system of consanguinity, a brother and sister can never be the father and mother of the same child – a thing, however, permissible in the Hawaiian family system. Probably the consanguine family was the state that, at the time of Herodotus, existed among the Massagetae, on the subject of which he reports: "Each man received a wife, but all were allowed to use her." And he continues: "At any time a man desires a woman, he hangs his quiver in front of his wagon, and cohabits, unconcerned, with her… He at the same time sticks his staff into the ground, a symbol of his own act… Cohabitation is exercised in public."³ Similar conditions Bachofen shows have existed among the Lycians, Etruscans, Cretans, Athenians, Lesbians and Egyptians.

According to Morgan, the consanguine family is supervened by a third and higher form of family relationship, which he designates as the Punaluan family. Punalua, "dear friend," "intimate companion."

Cunow, in his above named book, takes exception to Morgan's views that the consanguine family, which rests on the organization of marriage classes by generations, preceded the punaluan family as an original organization. Cunow does not see in the consanguine family the most primitive of all social forms, until now discovered. He sees in it merely a middle form, that takes its origin in the generation groups; a transition stage toward the pure gentile organization, on which, as a graft, the division in age classes, belonging to the consanguine family system, still continues for a time in altered form, along with the division in totem-groups.⁴ Cunow explains further: The division in classes – every individual, man or woman, carries the name of his or her class and generation group totem – does not serve to exclude sexual intercourse between collateral, but to prevent cohabitation between relatives in the ascending and descending line, between parents and children, aunts and nephews, uncles and nieces. Terms such as "aunt," "uncle," etc., he designates as grade-names.

Cunow furnishes the proofs for the correctness of the views in which he differs from Morgan on some points. But, however he may differ from Morgan in single instances, he emphatically defends him against the attacks of Westermann and others. He says:

"Although here and there a hypothesis of Morgan may have proved itself false, and some others may be allowed only a qualified approval, that merit none can gainsay him that he has been the first to establish the identity of the North American totem-group with the gentile organization of the Romans; and, secondly, to demonstrate that our modern systems of consanguinity and family-forms are the result of a long process of development. In a measure he has thereby first made recent investigations possible; he has first built the foundation on which we may build further." In the introduction also to his book he says expressly that his own work is partly a supplement to Morgan's book on primitive man.

The Westermanns, the Starckes, the Zieglers – the latter of whom, in his book, criticized in the introduction to the twenty-fifth edition of this work, refers mainly to the first named, in order to attack our statements with theirs – will have to submit, with good grace or bad, to the fact that the rise and development of the family has not taken the course that fits in with their bourgeois prejudices. The refutation that, in the last part of his work, Cunow bestows upon Westermann and Starcke, Ziegler's authorities, are calculated to enlighten their most fanatic followers upon the value of their caviling criticisms of, and arguments against, Morgan.

According to Morgan, the punaluan family has its start with the exclusion of consanguineous brothers and sisters, on the mother's side. Where a woman has several husbands, the evidence of paternity is impossible. Paternity becomes a fiction. Even to-day, under the rule of strict monogamous marriage, paternity, as Goethe, in his "Apprenticeship," lets Frederick say, "rests only upon faith." If with monogamy, paternity is often doubtful, it is impossible of proof in polygamy: only descent from the mother is certain and unquestionable. Accordingly, descent from the mother afforded the only criterion. As all deep-reaching transformations in the social relations of primitive man are accomplished only slowly, the change of the so-called consanguine into the punaluan family must unquestionably have engaged vast periods of time, and been broken through by many relapses, still noticeable in much later days. The proximate external inducement for the development of the punaluan family was, possibly, the necessity of splitting up the strongly swollen membership of the family, to the end that new grounds could be occupied for cattle ranges and agriculture. Probably, also, with the reaching of a higher grade of civilization, a sense gradually asserted itself of the harmfulness and indecorousness of sexual intercourse between brothers and sisters, and close relatives. In favor of this theory stands a pretty tradition, that, as related by Cunow, Gaston found among the Dieyeries, one of the South Australian tribes, on the rise of the "Mordu" consanguine group. He says:

"After creation, fathers, mothers, sisters, brothers and other near relatives married promiscuously among one another, until the evil effects of such connections showed themselves clearly. A conference of leaders was held, and it was considered in what way this could be avoided. The outcome of the conference was a request to the Muramura (Great Spirit); and he ordered in his answer that the tribe be divided into several branches, and that, in order to distinguish them, they be called by different names, after animate or inanimate objects. For instance: after the dingo, the mouse, the emu, the rain, the iguana-lizard, etc. The members of one and the same group could not marry another. The son of a Dingo could not, for instance, marry the daughter of a Dingo; each of the two could, however, enter into connections with the Mouse, the Emu, the Rat, or any other family."

This tradition is more sensible and natural, by a good deal, than the Christian tradition, taught by the Bible. It shows plainly the rise of the consanguine groups. Moreover, Paul Lafargue, makes in the "Neue Zeit" the sagacious, and, we think, felicitous point, that names, such as Adam and Eve, are not names of individual persons, but the names of gentes, in which, at the time, the Jews were joined. Lafargue solves by his argument a series of otherwise obscure and contradictory passages in the first Book of Moses. Again, M. Beer calls attention, likewise in the "Neue Zeit," that, to this day, it is a conjugal custom among Jews that the bride and the bridegroom's mother may not carry the same name, otherwise – thus runs this belief – a misfortune will befall the family: sickness and death will pursue them. In our opinion, this is a further proof for the correctness of Lafargue's theory. The gentile organization forbids marriage between persons that descend from the same gens stock. Such a common descent must be considered to exist, according to gentile principles, between the bride, that carries the name of "Eve," and the bridegroom's mother of the same name. Modern Jews, of course, have no longer the remotest suspicion of the real connection between their prejudice and their old gentile constitution, which forbade such marriages of relatives. The old gentile order had for its object to avoid the degenerating consequences of in-breeding. Although this gentile constitution has for thousands of years been destroyed among the Jews, tradition, as we see, has continued to live in superstition.

Quite possible, the experience, made at an early day with the breeding of animals, revealed the harmfulness of in-breeding. How far this experience went transpires from the manner in which, according to the first Book of Moses, chap. 30, verse 32 and sequel, Jacob understood how to outwit his father-in-law Laban, by knowing how to encompass the birth of eanlings that were streaked and pied, and which, according to Laban's promises, were to be Jacob's. The old Israelites had, accordingly, long before Darwin, studied Darwinism.

Once upon the subject of the conditions existing among the old Jews, a few other facts are in order, clearly proving that, among them, descent in the female line was actually in force of old. True enough, on the subject of woman, I Moses, 3, 16, runs this wise: "And thy desire shall be to thy husband, and he shall rule over thee;" and the verse also undergoes the variation: "the woman shall leave father and mother, and cleave to her husband." In point of fact, however, I Moses, 2, 24, has it this way: "Therefore shall a man leave his father and mother and shall cleave unto his wife, and they shall be one flesh." The same language recurs in Matthew 19, 15; Mark 10, 7, and in the Epistle to the Ephesians 5, 31. The command sprang, accordingly, from the system of descent in the female line, and the exegetists, at a loss what to do with it, allowed it to appear in a light that is utterly false.

Descent in female line appears clearly also in IV Moses, 32, 41. It is there said that Jair had a father, who was of the tribe of Judah, but his mother was of the tribe of Manasseh, and Jair is expressly called the son of Manasseh, and he inherited in that tribe. Another instance of descent in the female line among the Jews is met in Nehemiah 7, 63. There the children of a priest, who took to wife one of the daughters of Barzillai – a Jewish clan – are called children of Barzillai; they are, accordingly, not called after the father, who, moreover, as a priest occupied a privileged position, but after the mother. For the rest, already in the days of the Old Testament, accordingly, in historic times, the father-right prevailed among the Jews, and the clan and tribe organization rested on descent in the male line. Accordingly, the daughters were shut off as heirs, as may be seen in I Moses 31, 14-15, where even Leah and Rachel, the daughters of Laban, complain: "Is there yet any portion or inheritance for us in our father's house? Are we not counted of him strangers? for he has sold us, and hath quite devoured also our money."
