It remains to notice an innovation upon the original constitution of the classes, and in favor of the gens, which reveals a movement, still pending, in the direction of the true ideal of the gens. It is shown in two particulars: firstly, in allowing each triad of gentes to intermarry with each other, to a limited extent; and secondly, to marry into classes not before permitted. Thus, Iguana-Murri can now marry Mata in the Kangaroo gens, his collateral sister, whereas originally he was restricted to Buta in the opposite three. So Iguana-Kubbi can now marry Kapota, his collateral sister. Emu-Kumbo can now marry Buta, and Emu-Ippai can marry Ippata in the Blacksnake gens, contrary to original limitations. Each class of males in each triad of gentes seems now to be allowed one additional class of females in the two remaining gentes of the same triad, from which they were before excluded. The memoranda sent by Mr. Fison, however, do not show a change to the full extent here indicated.[49]
This innovation would plainly have been a retrograde movement but that it tended to break down the classes. The line of progress among the Kamilaroi, so far as any is observable, was from classes into gentes, followed by a tendency to make the gens instead of the class the unit of the social organism. In this movement the overshadowing system of cohabitation was the resisting element. Social advancement was impossible without diminishing its extent, which was equally impossible so long as the classes, with the privileges they conferred, remained in full vitality. The jura conjugialia, which appertained to these classes, were the dead weight upon the Kamilaroi, without emancipation from which they would have remained for additional thousands of years in the same condition, substantially, in which they were found.
An organization somewhat similar is indicated by the punalua of the Hawaiians which will be hereafter explained. Wherever the middle or lower stratum of savagery is uncovered, marriages of entire groups under usages defining the groups, have been discovered either in absolute form, or such traces as to leave little doubt that such marriages were normal throughout this period of man’s history. It is immaterial whether the group, theoretically, was large or small, the necessities of their condition would set a practical limit to the size of the group living together under this custom. If then community of husbands and wives is found to have been a law of the savage state, and, therefore, the essential condition of society in savagery, the inference would be conclusive that our own savage ancestors shared in this common experience of the human race.
In such usages and customs an explanation of the low condition of savages is found. If men in savagery had not been left behind, in isolated portions of the earth, to testify concerning the early condition of mankind in general, it would have been impossible to form any definite conception of what it must have been. An important inference at once arises, namely, that the institutions of mankind have sprung up in a progressive connected series, each of which represents the result of unconscious reformatory movements to extricate society from existing evils. The wear of ages is upon these institutions, for the proper understanding of which they must be studied in this light. It cannot be assumed that the Australian savages are now at the bottom of the scale, for their arts and institutions, humble as they are, show the contrary; neither is there any ground for assuming their degradation from a higher condition, because the facts of human experience afford no sound basis for such an hypothesis. Cases of physical and mental deterioration in tribes and nations may be admitted, for reasons which are known, but they never interrupted the general progress of mankind. All the facts of human knowledge and experience tend to show that the human race, as a whole, have steadily progressed from a lower to a higher condition. The arts by which savages maintain their lives are remarkably persistent. They are never lost until superseded by others higher in degree. By the practice of these arts, and by the experience gained through social organizations, mankind have advanced under a necessary law of development, although their progress may have been substantially imperceptible for centuries. It was the same with races as with individuals, although tribes and nations have perished through the disruption of their ethnic life.
The Australian classes afford the first, and, so far as the writer is aware, the only case in which we are able to look down into the incipient stages of the organization into gentes, and even through it upon an anterior organization so archaic as that upon sex. It seems to afford a glimpse at society when it verged upon the primitive. Among other tribes the gens seems to have advanced in proportion to the curtailment of the conjugal system. Mankind rise in the scale and the family advances through its successive forms, as these rights sink down before the efforts of society to improve its internal organization.
The Australians might not have effected the overthrow of the classes in thousands of years if they had remained undiscovered; while more favored continental tribes had long before perfected the gens, then advanced it through its successive phases, and at last laid it aside after entering upon civilization. Facts illustrating the rise of successive social organizations, such as that upon sex, and that upon kin are of the highest ethnological value. A knowledge of what they indicate is eminently desirable, if the early history of mankind is to be measurably recovered.
Among the Polynesian tribes the gens was unknown; but traces of a system analogous to the Australian classes appear in the Hawaiian custom of punalua. Original ideas, absolutely independent of previous knowledge and experience, are necessarily few in number. Were it possible to reduce the sum of human ideas to underived originals, the small numerical result would be startling. Development is the method of human progress.
In the light of these facts some of the excrescences of modern civilization, such as Mormonism, are seen to be relics of the old savagism not yet eradicated from the human brain. We have the same brain, perpetuated by reproduction, which worked in the skulls of barbarians and savages in by-gone ages; and it has come down to us ladened and saturated with the thoughts, aspirations and passions, with which it was busied through the intermediate periods. It is the same brain grown older and larger with the experience of the ages. These outcrops of barbarism are so many revelations of its ancient proclivities. They are explainable as a species of mental atavism.
Out of a few germs of thought, conceived in the early ages, have been evolved all the principal institutions of mankind. Beginning their growth in the period of savagery, fermenting through the period of barbarism, they have continued their advancement through the period of civilization. The evolution of these germs of thought has been guided by a natural logic which formed an essential attribute of the brain itself. So unerringly has this principle performed its functions in all conditions of experience, and in all periods of time, that its results are uniform, coherent and traceable in their courses. These results alone will in time yield convincing proofs of the unity of origin of mankind. The mental history of the human race, which is revealed in institutions, inventions and discoveries, is presumptively the history of a single species, perpetuated through individuals, and developed through experience. Among the original germs of thought, which have exercised the most powerful influence upon the human mind, and upon human destiny, are these which relate to government, to the family, to language, to religion, and to property. They had a definite beginning far back in savagery, and a logical progress, but can have no final consummation, because they are still progressing, and must ever continue to progress.
