With these two methods working together, more light is continually being thrown upon man's ancient culture. To ill.u.s.trate this, if a certain kind of tool or implement is found in the culture areas of the extinct Neanderthal race and a similar tool is used by a living Australian tribe, it may be conjectured with considerable accuracy that the use of this tool was for similar purposes, and the thoughts and beliefs that cl.u.s.tered around its use were the same in each tribe.

Thus may be estimated the degree of progress of the primitive race. Or if an inscription on a cave of an extinct race showed a similarity to an inscription used by a living race, it would seem that they had the same background for such expression, and that similar instincts, emotions, and reflections were directed to a common end. The recent study of anthropologists and archaeologists has brought to light much knowledge of primitive man which may be judged on its own evidence and own merits. The verification of these early cultures by the living races who have reached a similar degree of progress is of great importance.

_The Study of Prehistoric Types_.[1]--The brain capacity of modern man has changed little since the time of the Cro-Magnon race, which is the earliest ancestral type of present European races and whose existence dates back many {29} thousand years. Possibly the weight of the brain has increased during this period because of its development, and undoubtedly its power is much greater in modern man than in this ancient type. Prior to that there are some evidences of extinct species, such as Pithecanthropus Erectus, the Grimaldi man, the Heidelberg man, and the Neanderthal. Judging from the skeletal remains that have been found of these races, there has been a general progress of cranial capacity. It is not necessary here to attempt to determine whether this has occurred from hereditary combinations or through changing environment. Undoubtedly both of these factors have been potential in increasing the brain power of man, and if we were to go farther back by way of a.n.a.logy, at least, and consider the Anthropoid ape, the animal most resembling man, we find a vast contrast in his cranial capacity as compared with the lowest of the prehistoric types, or, indeed, of the lowest types of the uncultured living races.

Starting with the Anthropoid ape, who has a register of about 350 c.c., the Pithecanthropus about 900 c.c., and Neanderthal types registering as high as 1,620 c.c. of brain capacity, the best measures of the highest types of modern man show the brain capacity of 1,650 c.c.

Specimens of the Cro-Magnon skulls show a brain capacity equal to that of modern man. There is a great variation in the brain capacity of the Neanderthal race as exhibited in specimens found in different centres of culture, ranging all the way from 1,296 c.c. to 1,620 c.c. Size is only one of several traits that determine brain power. Among others are the weight, convolutions, texture, and education. A small, compact brain may have more power than a larger brain relatively lighter. Also much depends upon the centres of development. The development of the frontal area, shown by the full forehead in connection with the distance above the ear (auditory meatus), in contrast with the development of the anterior lobes is indicative of power.

It is interesting to note also that the progress of man as shown in the remnants of arts and industry corresponds in {30} development to the development of brain capacity, showing that the physical power of man kept pace with the mental development as exhibited in his mental power displayed in the arts and industries. The discoveries in recent times of the skeletons of prehistoric man in Europe, Africa, and America, and the increased collection of implements showing cultures are throwing new light on the science of man and indicating a continuous development from very primitive beginnings.

_Progress Is Indicated by the Early Cultures_.--It is convenient to divide the early culture of man, based upon his development in art into the Paleolithic, or unpolished, and the Neolithic, or polished, Stone Ages.[2] The former is again divided into the Eolithic, Lower Paleolithic, and the Upper Paleolithic. In considering these divisions of relative time cultures, it must be remembered that the only way we have of measuring prehistoric time is through the geological method, based upon the Ice Ages and changes in the physical contour of the earth.

In the strata of the earth, either in the late second inter-glacial period or at the beginning of the third, chipped rocks, or eoliths, are found used by races of which the Piltdown and Heidelberg species are representatives.[3] Originally man used weapons to hammer and to cut already prepared by nature. Sharp-edged flints formed by the crushing of rocks in the descent of the glaciers or by upheavals of earth or by powerful torrents were picked up as needed for the purpose of cutting.

Wherever a sharp edge was needed, these natural implements were useful.

Gradually man learned to carry the best specimens with him. These he improved by chipping the edges, making them more serviceable, or chipping the eolith, so as to grasp it more easily. This represents the earliest relic of the beginning of civilization through art.

Eoliths of this kind are found in Egypt in the hills bordering the Nile Valley, in Asia and America, as well as in southern Europe. Perhaps at the same period of development man selected stones suitable for crushing bones or for other purposes when hammering {31} was necessary.

These were gradually fashioned into more serviceable hammers. In the latter part of this period, known as the pre-Ch.e.l.lean, flint implements were considerably improved.

In the Lower Paleolithic in the pre-Neanderthal period, including what is known as the Ch.e.l.lean, new forms of implements are added to the earlier beginnings. Almond-shaped flint implements, followed later by long, pointed implements, indicate the future development of the stone spear, arrowhead, knife, and axe. Also smaller articles of use, such as borers, sc.r.a.pers, and ploughs, appeared. The edges of all implements were rough and uneven, and the forms very imperfect.

_Industrial and Social Life of Primitive Man_.--In the industry of the early Neanderthal races (Acheulean) implements were increased in number and variety, being also more perfectly formed, showing the expansive art of man. At this period man was a hunter, having temporary homes in caves and shelters, which gradually became more or less permanent, and used well-fashioned implements of stone. At the close of the third interglacial period the climate was mild and moist, and mankind found the open glades suitable places for a.s.semblages in family groups about the open fires; apparently the cooking of food and the making of implements and clothing on a small scale were the domestic occupations at this time. Hunting was the chief occupation in procuring food. The bison, the horse, the reindeer, the bear, the beaver, the wild boar had taken the place of the rhinoceros, the sabre-tooth tiger, and the elephant.

Judging from the stage of life existing at this time, and comparing this with that of the lowest living races, we may safely infer that the family a.s.sociations existed at this time, even though the habitations in caves and shelters were temporary.[4]

"Yet, when at length rude huts they first devised, And fires and garments; and in union sweet Man wedded woman, the pure joys indulged

{32}

Of chaste connubial love, and children rose, The rough barbarians softened. The warm hearth Their frames so melted they no more could bear, As erst, th' uncovered skies. The nuptial bed Broke their wild vigor, and the fond caress Of prattling children from the bosom chased Their stern, ferocious manners."

--LUCRETIUS, "ON THE NATURE OF THINGS."

AFTER OSBORN.

Thus the Lower Paleolithic merged into the Upper; with the appearance of the Mousterian, Augrignacian, Solutrian, Magdalenian, and Azilian cultures followed the most advanced stage of the Neanderthal race before its final disappearance. The list of tools and implements indicates a widening scope of civilization. For war and chase and fishing, for industry and domestic life, for art, sculpture, and engraving, and for ceremonial use, a great variety of implements of stone and bone survived the life of the races.

Spears, daggers, knives, arrowheads, fish-hooks, and harpoons; hand-axes, drills, hammers, sc.r.a.pers, planes, needles, pins, chisels, wedges, gravers, etchers, mortars, and pilasters; ceremonial staffs and wands--all are expressions of a fulness of industrial and social life not recognized in earlier races. Indications of religious ceremonies represent the changing mind, and the expression of mind in art suggests increased mental power.

_Cultures Indicate the Mental Development of the Race_.--As the art and industry to-day represent the mental processes of man, so did these primitive cultures show the inventive skill and adaptive power in the beginnings of progress. Perhaps instinct, emotion, and necessity figured more conspicuously in the early period than reflective thought, while in modern times we have more design and more planning, both in invention and construction. Also the primitive social order was more an unconscious development, and lacked purpose and directing power in comparison with present life.

{33}

But there must have been inventors and leaders in primitive times, some brains more fertile than others, that made change and progress possible. Who these unknown geniuses were human records do not indicate. In modern times we single out the superiors and call them great. The inventor, the statesman, the warrior, the king, have their achievements heralded and recorded in history. The records of achievement of the great barbarous cultures, of the a.s.syrians, the Egyptians, and the Hebrews, centre around some king whose tomb preserves the only records, while in reality some man unknown to us was the real author of such progress as was made. The reason is that progress was so slow that the changes pa.s.sed unnoticed, being the products of many minds, each adding its increment of change. Only the king or ruler who could control the ma.s.s mind and the ma.s.s labor could make sufficient spectacular demonstration worth recording, and could direct others to build a tomb or record inscriptions to perpetuate his name.

_Men of Genius Cause the Mutations Which Permit Progress_.--The toiling mult.i.tudes always use the products of some inventive genius. Some individual with specialized mental traits plans something different from social usages or industrial life which changes tradition and modifies the customs and habits of the ma.s.s. Whether he be statesman, inventor, philosopher, scientist, discoverer, or military leader, he usually receives credit for the great progressive mutation which he has originated. There can be little progress without these few fertile brains, just as there could be little progress unless they were supported by the laborers who carry out the plans of the genius. While the "unknown man" is less conspicuous in the progress of the race in modern complex society, he is still a factor in all progress.

_The Data of Progress_.--Evolution is not necessarily progress; neither is development progress; yet the factors that enter into evolution and development are essential to progress. The laws of differentiation apply to progress as well as to evolution. In the plant and animal life everywhere this law {34} obtains. In man it is subservient to the domination of intelligent direction, yet it is in operation all of the time. Some races are superior in certain lines, other races show superiority in other lines. Likewise, individuals exhibit differences in a similar way. Perhaps the dynamic physical or mental power of the individual or the race will not improve in itself, having reached its maximum. There is little hope that the brain of man will ever be larger or stronger, but it may become more effective through training and increased knowledge. Hence in the future we must look for achievement along co-operative and social lines. It is to social expansion and social perfection that we must look for progress in the future. For here the acc.u.mulated power of all may be utilized in providing for the welfare of the individual, who, in turn, will by his inventive power cause humanity to progress.

The industrial, inst.i.tutional, humanitarian, and educational machinery represents progress in action, but increased knowledge, higher ideals of life, broader concepts of truth, liberty of individual action which is interested in human life in its entirety, are the real indices of progress.

METHODS OF RECOUNTING HUMAN PROGRESS

_Difficulty of Measuring Progress_.--In its larger generalization, progress may move in a straight line, but it has such a variety of expression and so many tributary causes that it is difficult to reduce it to any cla.s.sification. Owing to the difficulties that attend an attempt to recite all of the details of human progress, philosophers and historians have approached the subject from various sides, each seeking to make, by means of higher generalizations, a clear course of reasoning through the labyrinth of materials. By adopting certain methods of marking off periods of existence and pointing out the landmarks of civilization, they have been able to estimate more truly the development of the race. Civilization cannot be readily measured by time; indeed, the time interval in history is of little value save to mark order and continuity. It has in itself no real significance; it is merely an arbitrary division whose importance is greatly exaggerated. But while civilization is a continuous quant.i.ty, and cannot be readily marked off into periods without destroying its movement, it is necessary to make the attempt, especially in the study of ancient or prehistoric society; for any method which groups and cla.s.sifies facts in logical order is helpful to the study of human progress.

_Progress May Be Measured by the Implements Used_.--A very common method, based largely upon the researches of archaeologists, is to divide human society into four great periods, or ages, marked by the progress of man in the use of implements. The first of these periods is called the Stone Age, and embraces the time when man used stone for all {36} purposes in the industrial arts so far as they had been developed. For convenience this period has been further divided into the age of ancient or unpolished implements and the age of modern or polished implements. The former includes the period when rude implements were chipped out of flint or other hard stone, without much idea of symmetry and beauty, and with no attempt to perfect or beautify them by smoothing and polishing their rough surface.

In the second period man learned to fashion more perfectly the implements, and in some instances to polish them to a high degree.

Although the divisions are very general and very imperfect, they map out the great prehistoric era of man; but they must be considered as irregular, on account of the fact that the Stone Era of man occurred at different times in different tribes. Thus the inhabitants of North America were in the Stone Age less than two centuries ago, while some of the inhabitants of the South Sea Islands are in the Stone Age during the present century. It is quite remarkable that the use of stone implements was universal to all tribes and nations at some period of their existence.

After the long use of stone, man gradually became acquainted with some of the metals, and subsequently discovered the method of combining copper with tin and other alloys to form bronze, which material, to a large extent, added to the implements already in use. The Bronze Age is the most hypothetical of all these divisions, as it does not appear to have been as universal as the Stone, on account of the difficulty of obtaining metals. The use of copper by the Indians of the Lake Superior region was a very marked epoch in their development, and corresponds to the Bronze Age of other nations, although their advancement in other particulars appears to be less than that of other tribes of European origin which used bronze freely. Bronze implements have been found in great plenty in Scandinavia and Peru, and to a limited extent in North America. They certainly mark a stage of progress in advance of that of the inhabitants of the Stone Age.

Bronze {37} was the chief metal for implements throughout the early civilization of Europe.

Following the age of bronze is the Iron Age, in which the advancement of man is especially marked. The bronze implements were at first supplemented in their use by those of iron. But gradually iron implements superseded the bronze. The Iron Age still is with us.

Possibly it has not yet reached its highest point. Considering the great structures built of iron, and the excessive use of iron in machinery, implements, and furniture, it is easy to realize that we are yet in this great period. Though we continue to use stone more than the ancients and more bronze for decoration and ornament than they, yet both are subordinate to the use of iron. General as the above cla.s.sification is, it helps in an indefinite way to give us a central idea of progress and to mark off, somewhat indefinitely, periods of development.

_The Development of Art_.--Utility was the great purpose underlying the foundation of the industrial arts. The stone axe, or celt, was first made for a distinct service, but, in order to perfect its usefulness, its lines became more perfect and its surface more highly polished. So we might say for the spear-head, the knife, or the olla. Artistic lines and decorative beauty always followed the purpose of use. This could be applied to all of the products of man's invention to transform parts of nature to his use. On account of the durability of form, the attempt to trace the course of civilization by means of the development of the fine arts has met with much success. Though the idea of beauty is not essential to the preservation of man or to the making of the state, it has exerted a great influence in individual-building and in society-building. In our higher emotional natures aesthetic ideas have ruled with imperial sway.
