With the production of inventions and discoveries, and with the growth of institutions, the human mind necessarily grew and expanded; and we are led to recognize a gradual enlargement of the brain itself, particularly of the cerebral portion. The slowness of this mental growth was inevitable, in the period of savagery, from the extreme difficulty of compassing the simplest invention out of nothing, or with next to nothing to assist mental effort; and of discovering any substance or force in nature available in such a rude condition of life. It was not less difficult to organize the simplest form of society out of such savage and intractable materials. The first inventions and the first social organizations were doubtless the hardest to achieve, and were consequently separated from each other by the longest intervals of time. A striking illustration is found in the successive forms of the family. In this law of progress, which works in a geometrical ratio, a sufficient explanation is found of the prolonged duration of the period of savagery.
That the early condition of mankind was substantially as above indicated is not exclusively a recent, nor even a modern opinion. Some of the ancient poets and philosophers recognized the fact, that mankind commenced in a state of extreme rudeness from which they had risen by slow and successive steps. They also perceived that the course of their development was registered by a progressive series of inventions and discoveries, but without noticing as fully the more conclusive argument from social institutions.
The important question of the ratio of this progress, which has a direct bearing upon the relative length of the several ethnical periods, now presents itself. Human progress, from first to last, has been in a ratio not rigorously but essentially geometrical. This is plain on the face of the facts; and it could not, theoretically, have occurred in any other way. Every item of absolute knowledge gained became a factor in further acquisitions, until the present complexity of knowledge was attained. Consequently, while progress was slowest in time in the first period, and most rapid in the last, the relative amount may have been greatest in the first, when the achievements of either period are considered in their relations to the sum. It may be suggested, as not improbable of ultimate recognition, that the progress of mankind in the period of savagery, in its relations to the sum of human progress, was greater in degree than it was afterwards in the three sub-periods of barbarism; and that the progress made in the whole period of barbarism was, in like manner, greater in degree than it has been since in the entire period of civilization.
What may have been the relative length of these ethnical periods is also a fair subject of speculation. An exact measure is not attainable, but an approximation may be attempted. On the theory of geometrical progression, the period of savagery was necessarily longer in duration than the period of barbarism, as the latter was longer than the period of civilization. If we assume a hundred thousand years as the measure of man’s existence upon the earth in order to find the relative length of each period—and for this purpose, it may have been longer or shorter—it will be seen at once that at least sixty thousand years must be assigned to the period of savagery. Three-fifths of the life of the most advanced portion of the human race, on this apportionment, were spent in savagery. Of the remaining years, twenty thousand, or one-fifth, should be assigned to the Older Period of barbarism. For the Middle and Later Periods there remain fifteen thousand years, leaving five thousand, more or less, for the period of civilization.
The relative length of the period of savagery is more likely under than over stated. Without discussing the principles on which this apportionment is made, it may be remarked that in addition to the argument from the geometrical progression under which human development of necessity has occurred, a graduated scale of progress has been universally observed in remains of ancient art, and this will be found equally true of institutions. It is a conclusion of deep importance in ethnology that the experience of mankind in savagery was longer in duration than all their subsequent experience, and that the period of civilization covers but a fragment of the life of the race.
Two families of mankind, the Aryan and Semitic, by the commingling of diverse stocks, superiority of subsistence or advantage of position, and possibly from all together, were the first to emerge from barbarism. They were substantially the founders of civilization.37 But their existence as distinct families was undoubtedly, in a comparative sense, a late event. Their progenitors are lost in the undistinguishable mass of earlier barbarians. The first ascertained appearance of the Aryan family was in connection with the domestic animals, at which time they were one people in language and nationality. It is not probable that the Aryan or Semitic families were developed into individuality earlier than the commencement of the Middle Period of barbarism, and that their differentiation from the mass of barbarians occurred through their acquisition of the domestic animals.
The most advanced portion of the human race were halted, so to express it, at certain stages of progress, until some great invention or discovery, such as the domestication of animals or the smelting of iron ore, gave a new and powerful impulse forward. While thus restrained, the ruder tribes, continually advancing, approached in different degrees of nearness to the same status; for wherever a continental connection existed, all the tribes must have shared in some measure in each other’s progress. All great inventions and discoveries propagate themselves; but the inferior tribes must have appreciated their value before they could appropriate them. In the continental areas certain tribes would lead; but the leadership would be apt to shift a number of times in the course of an ethnical period. The destruction of the ethnic bond and life of particular tribes, followed by their decadence, must have arrested for a time, in many instances and in all periods, the upward flow of human progress. From the Middle Period of barbarism, however, the Aryan and Semitic families seem fairly to represent the central threads of this progress, which in the period of civilization has been gradually assumed by the Aryan family alone.
The truth of this general position may be illustrated by the condition of the American aborigines at the epoch of their discovery. They commenced their career on the American continent in savagery; and, although possessed of inferior mental endowments, the body of them had emerged from savagery and attained to the Lower Status of barbarism; whilst a portion of them, the Village Indians of North and South America, had risen to the Middle Status. They had domesticated the llama, the only quadruped native to the continent which promised usefulness in the domesticated state, and had produced bronze by alloying copper with tin. They needed but one invention, and that the greatest, the art of smelting iron ore, to advance themselves into the Upper Status. Considering the absence of all connection with the most advanced portion of the human family in the Eastern hemisphere, their progress in unaided self-development from the savage state must be accounted remarkable. While the Asiatic and European were waiting patiently for the boon of iron tools, the American Indian was drawing near to the possession of bronze, which stands next to iron in the order of time. During this period of arrested progress in the Eastern hemisphere, the American aborigines advanced themselves, not to the status in which they were found, but sufficiently near to reach it while the former were passing through the last period of barbarism, and the first four thousand years of civilization. It gives us a measure of the length of time they had fallen behind the Aryan family in the race of progress: namely the duration of the Later Period of barbarism, to which the years of civilization must be added. The Aryan and Ganowánian families together exemplify the entire experience of man in five ethnical periods, with the exception of the first portion of the Later Period of savagery.
Savagery was the formative period of the human race. Commencing at zero in knowledge and experience, without fire, without articulate speech and without arts, our savage progenitors fought the great battle, first for existence, and then for progress, until they secured safety from ferocious animals, and permanent subsistence. Out of these efforts there came gradually a developed
