CHAPTER V

THE ECONOMIC FACTORS OF PROGRESS

_The Efforts of Man to Satisfy Physical Needs_.--All knowledge of primitive man, whether derived from the records of cultures he has left or a.s.sumed from a.n.a.logy of living tribes of a low order of civilization, discovers him wandering along the streams in the valleys or by the sh.o.r.es of lakes and oceans, searching for food and incidentally seeking protection in caves and trees. The whole earth was his so far as he could appropriate it. He cared nothing for ownership; he only wanted room to search for the food nature had provided. When he failed to find sufficient food as nature left it, he starved. So in his wandering life he adapted himself to nature as he found it. In the different environments he acquired different customs and habits of life. If he came in contact with other tribes, an exchange of knowledge and customs took place, and both tribes were richer thereby. However, the universality of the human mind made it possible for two detached tribes, under similar environment and similar stimuli, to develop the same customs and habits of life, provided they had the same degree of development. Hence, we have independent group development and group borrowing.

When nature failed to provide him with sufficient food, he learned to force her to yield a larger supply. When natural objects were insufficient for his purposes, he made artificial tools to supplement them. Slowly he became an inventor. Slowly he mastered the art of living. Thus physical needs were gradually satisfied, and the foundation for the superstructure of civilization was laid.

_The Attempt to Satisfy Hunger and to Protect from Cold_.--To this statement must be added the fact that struggle with {83} his fellows arose from the attempt to obtain food, and we have practically the whole occupation of man in a state of savagery. At least, the simple activities represent the essential forces at the foundation of human social life. The attempt to preserve life either through instinct, impulse, emotion, or rational selection is fundamental in all animal existence. The other great factor at the foundation of human effort is the desire to perpetuate the species. This, in fact, is the mere projection of the individual life into the next generation, and is fundamentally important to the individual and to the race alike. All modern efforts can be traced to these three fundamental activities.

But in seeking to satisfy the cravings of hunger and to avoid the pain of cold, man has developed a varied and active life. About these two centres cl.u.s.ter all the simple forces of human progress. Indeed, invention and discovery and the advancement of the industrial arts receive their initial impulses from these economic relations.

We have only to turn our attention to the social life around us to observe evidences of the great importance of economic factors. Even now it will be observed that the greater part of economic activities proceeds from the effort to procure food, clothing, and shelter, while a relatively smaller part is engaged in the pursuit of education, culture, and pleasure. The excellence of educational systems, the highest flights of philosophy, the greatest achievement of art, and the best inspiration of religion cannot exist without a wholesome economic life at the foundation. It should not be humiliating to man that this is so, for in the const.i.tution of things, labor of body and mind, the struggle for existence and the acc.u.mulations of the products of industry yield a large return in themselves in discipline and culture; and while we use these economic means to reach higher ideal states, they represent the ladder on which man makes the first rounds of his ascent.

_The Methods of Procuring Food in Primitive Times_.--Judging from the races and tribes that are more nearly in a state of nature than any other, it may be reasonably a.s.sumed that {84} in his first stage of existence, man subsisted almost wholly upon a vegetable diet, and that gradually he gave more and more attention to animal food. His structure and physiology make it possible for him to use both animal and vegetable food. Primarily, with equal satisfaction the procuring of food must have been rather an individual than a social function.

Each individual sought his own breakfast wherever he might find it. It was true then, as now, that people proceeded to the breakfast table in an aggregation, and flocked around the centres of food supply; so we may a.s.sume the picture of man stealing away alone, picking fruits, nuts, berries, gathering clams or fish, was no more common than the fact of present-day man getting his own breakfast alone. The main difference is that in the former condition individuals obtained the food as nature left it, and pa.s.sed it directly from the bush or tree to the mouth, while in modern times thousands of people have been working indirectly to make it possible for a man to wait on himself.

Jack London, in his _Before Adam_, gives a very interesting picture of the tribe going out to the carrot field for its breakfast, each individual helping himself. However, such an aggregation around a common food supply must eventually lead to co-operative economic methods. But we do find even among modern living tribes of low degree of culture the group following the food quest, whether it be to the carrot patch, the nut-bearing trees, the sedgy seash.o.r.e for mussels and clams, the lakes for wild rice, or to the forest and plains where abound wild game.

We find it difficult to think otherwise than that the place of man's first appearance was one abounding in edible fruits. This fact arises from the study of man's nature and evidences of the location of his first appearance, together with the study of climate and vegetation.

There are a good many suggestions also that man in his primitive condition was prepared for a vegetable diet, and indications are that later he acquired use of meat as food. Indeed, the berries and edible roots of {85} certain regions are in sufficient quant.i.ty to sustain life throughout a greater part of the year. The weaker tribes of California at the time of the first European invaders, and for many centuries previous, found a greater part of their sustenance in edible roots extracted from the soil, in nuts, seeds of wild grains, and gra.s.ses. It is true they captured a little wild game, and in certain seasons many of them made excursions to the ocean or frequented the streams for fish or sh.e.l.l-fish, but their chief diet was vegetable. It must be remembered, also, that all of the cultivated fruits to-day formerly existed, in one variety or another, in the wild species. Thus the citrous fruits, the date, the banana, breadfruit, papaw, persimmon, apple, cherry, plum, pear, all grew in a wild state, providing food for man if he were ready to take it as provided. Rational selection has a.s.sisted nature in improving the quality of grains and fruits and in developing new varieties.

In the tropical regions was found the greatest supply of edible fruits.

Thus the Malays and the Papuans find sufficient food on trees to supply their wants. Many people in some of the groups in the South Sea Islands live on cocoanuts. In South America several species of trees are cultivated by the natives for the food they furnish. The palm family contributes much food to the natives, and also furnishes a large supply of food to the markets of the world. The well-known breadfruit tree bears during eight successive months in the year, and by burying the fruit in the ground it may be preserved for food for the remaining four months. Thus a single plant may be made to provide a continuous food supply for the inhabitants of the Moluccas and Philippines. Many other instances of fruits in abundance, such as the nuts from the araucarias of South America, and beans from the mesquite of Mexico, might be given to show that it is possible for man to subsist without the use of animal food.

_The Variety of Food Was Constantly Increased_.--Undoubtedly, one of the chief causes of the wandering of primitive man over the earth, in the valleys, along stream, lake, and ocean, {86} over the plains and through the hills, was the quest for food to preserve life; and even after tribes became permanent residents in a certain territory, there was a constant shifting from one source of food supply to another throughout the seasons. However, after tribes became more settled, the increase of population encroached upon the native food supply, and man began to use his invention for the purpose of its increase. He learned how to plant seeds which were ordinarily believed to be sown by the G.o.ds, and to till the soil and raise fruits and vegetables for his own consumption. This was a period of accidental agriculture, or hoe culture, whereby the ground was tilled by women with hoes of stone, or bone, or wood. In the meantime, the increase of animal food became a necessity. Man learned how to snare and trap animals, to fish and to gather sh.e.l.l-fish, learning by degrees to use new foods as discovered as nature left them. Life become a veritable struggle for existence as the population increased and the lands upon which man dwelt yielded insufficient supply of food. The increased variety of food allowed man to adapt himself to the different climates. Thus in the colder climates animal food became desirable to enable him to resist more readily the rigors of climate. It was not necessary, it is supposed, to give him physical courage or intellectual development, for there appear to be evidences of tribes like the Maoris of New Zealand, who on the diet of fish and roots became a most powerful and sagacious people.

But the change from a vegetable diet to a meat-and-fish diet in the early period brought forth renewed energy of body and mind, not only on account of the necessary physical exertion but on account of the invention of devices for the capture of fish and game.

_The Food Supply Was Increased by Inventions_.--Probably the first meat food supply was in the form of sh.e.l.l-fish which could be gathered near the sh.o.r.es of lakes and streams. Probably small game was secured by the use of stones and sticks and by running the animal down until he was exhausted or until he hid in a place inaccessible to the pursuer.

The {87} boomerang, as used by the Australians in killing game, may have been an early product of the people of Neolithic Europe. In the latter part of the Paleolithic Age, fish-hooks of bone were used, and probably snares invented for small game. The large game could not be secured without the use of the spear and the co-operation of a number of hunters. In all probability this occurred in the New Stone Age.

The invention of the bow-and-arrow was of tremendous importance in securing food. It is not known what led to its invention, although the discovery of the flexible power of the shrub, or the small sapling, must have occurred to man as he struggled through the brush. It is thought by some that the use of the bow fire-drill, which was for the purpose of striking fire by friction, might have displayed driving power when the drill wound up in the string of the bow flew from its confinement. However, this is conjectural; but, judging from the inventions of known tribes, it is evident that necessity has always been the moving power in invention. The bow-and-arrow was developed in certain centres and probably through trade and exchange extended to other tribes and groups until it was universally used. It is interesting to note how many thousands of years this must have been the chief weapon for destroying animals or crippling game at a distance.

Even as late as the Norman conquest, the bow-and-arrow was the chief means of defense of the Anglo-Saxon yeoman, and for many previous centuries in the historic period had been the chief implement in warfare and in the chase. The use of the spear in fishing supplemented that of the hook, and is found among all low-cultured tribes of the present day. The American Indian will stand on a rock in the middle of a stream, silently, for an hour if necessary, watching for a chance to spear a salmon. These small devices were of tremendous importance in increasing the food supply, and the making of them became a permanent industry.

Along with the bow and arrow were developed many kinds of spears, axes, and hammers, invented chiefly to be used in {88} war, but also used for economic reasons. In the preparation of animal food, in the tanning of skins, in the making of clothing, another set of stone implements was developed. So, likewise, in the grinding of seeds, the mortar and pestle were used, and the small hand-mill or grinder was devised. The sign of the mortar and pestle at the front of drug-stores brings to mind the fact that its first use was not for preparing medicines, but for grinding grains and seeds.

_The Discovery and Use of Fire_.--The use of fire was practised in the early history of man. Among the earliest records in caves are found evidences of the use of fire. Charcoal is practically indestructible, and, although it may be crushed, the small particles maintain their shape in the clays and sands. In nearly all of the relics of man discovered in caves, the evidences of fire are to be found, and no living tribe has yet been discovered so low in the scale of life as to be without the knowledge of fire and probably its simple uses, although a few tribes have been for the time being without fire when first discovered. This might seem to indicate that at a very early period man did not know how to create fire artificially, but carried it and preserved it in his wanderings. There are indications that a certain individual was custodian of the fire, and later it was carried by the priest or _cacique_. Here, as in other instances in the development of the human race, an economic factor soon a.s.sumes a religious significance, and fire becomes sacred.

There are many conjectures respecting the discovery of fire. Probably the two real sources are of lightning that struck forest trees and set them on fire and the action of volcanoes in throwing out burning lava, which ignited combustible material. Either one or the other, and perhaps both, of these methods may have furnished man with fire.

Others have suggested that the rubbing together of dead limbs of trees in the forests after they were moved by the winds, may have created fire by friction. It is possible, also, that the sun's rays may have, when concentrated on combustible {89} material, caused spontaneous ignition. The idea has been advanced that some of the forest fires of recent times have been ignited in this way. However, it is evident that there are enough natural sources in the creation of fire to enable tribes to use it for the purposes of artificial heat, cooking, and later, in the age of metals, of smelting ores.

There has always been a mystery connected with the origin and use of fire, which has led to many myths. Thus, the Greeks insisted that Prometheus, in order to perform a great service to humanity, stole fire from heaven and gave it to man. For this crime against the authority of the G.o.ds, he was chained to a rock to suffer the torture of the vulture who pecked at his vitals. Aeschylus has made the most of this old legend in his great drama of _Prometheus Bound_. Nearly every tribe or nation has some tradition regarding the origin of fire.

Because of its mystery and its economic value, it was early connected with religion and made sacred in many instances. It was thus preserved at the altar, never being allowed to become extinct without the fear of dire calamity. Perhaps the economic and religious ideas combined, because tribes in travelling from place to place exercised great care to preserve it. The use of fire in worship became almost universal among tribes and ancient nations. Thus the Hebrews and the Aryans, including Greeks, Romans, and Persians, as well as the Chinese and j.a.panese, used fire in worship. Among other tribes it was worshipped as a symbol or even as a real deity. Even in the Christian religion, the use of the burning incense may have some psychological connection with the idea of purification through fire. Whether its mysterious nature led to its connection with worship, and the superst.i.tion connected with its continued burning, or whether from economic reasons it became a sacred matter, has never been determined. The custom that a fire should never go out upon the altar, and that it should be carried in migrations from place to place, would seem to indicate that these two motives were closely allied, if not related in cause and effect.

{90}

Evidently, fire was used for centuries before man invented methods of reproducing it. Simple as the process involved, it was a great invention; or it may be stated that many devices were resorted to for the creation of artificial fire. Perhaps the earliest was that of rubbing two pieces of dry wood together, producing fire by friction.

This could be accomplished by persistent friction of two ordinary pieces of dry wood, or by drilling a hole in a dry piece of wood with a pointed stick until heat was developed and a spark produced to ignite pieces of dry bark or gra.s.s. Another way was to make a groove in a block of wood and run the end of a stick rapidly back and forth through the groove. An invention called the fire-drill was simply a method of twirling rapidly in the hand a wooden drill which was in contact with dry wood, or by winding a string of the bow several times around the drill and moving the bow back and forth horizontally, giving rapid motion to the drill.

As tribes became more advanced, they used two pieces of flint with which to strike fire, and after the discovery of iron, the flint and iron were used. How many centuries these simple devices were essential to the progress and even to the life of tribes, is not known; but when we realize that but a few short years ago our fathers lighted the fire with flint and steel, and that before the percussion cap was invented, the powder in the musket was ignited by flint and hammer, we see how important to civilization were these simple devices of producing fire artificially. So simple an invention as the discovery of the friction match saved hours of labor and permitted hours of leisure to be used in other ways. It is one of the vagaries of human progress that a simple device remains in use for thousands of years before its clumsy method gives way to a new invention only one step in advance of the old.

_Cooking Added to the Economy of the Food Supply_.--Primitive man doubtless consumed his food raw. The transition of the custom of uncooked food to cooked food must have been gradual. We only know that many of the backward tribes of {91} to-day are using primitive methods of cooking, and the man of the Stone Ages had methods of cooking the meat of animals. In all probability, the suggestion came as people were grouped around the fire for artificial heat, and then, either by intention or desire, the experiment of cooking began. After man had learned to make water-tight baskets, a common device of cooking was to put water in the basket and, after heating stones on a fire, put them in the basket to heat the water and then place the food in the basket to be cooked. This method is carried on by the Indians in some parts of Alaska to this day, where they use a water-tight basket for this purpose. Probably this method of cooking food was a later development than the roasting of food on coals or in the ashes, or in the use of the wooden spit. Catlin, in his _North American Indians_, relates that certain tribes of Indians dig a hole in the ground and line it with hide filled with water, then place hot stones in the water, in which they place their fish, game, or meat for cooking. This is interesting, because it carries out a more or less universal idea of adaptation to environment. Probably the plains Indians had no baskets or other vessels to use for this purpose, but they are found to have used similar methods of cooking gra.s.shoppers. They dig a hole in the ground, build a fire in the hole, and take the fire out and put in the gra.s.shoppers. Thus, they have an exhibition of the first fireless cooker.

It is thought by some that the need of vessels which would endure the heat was the cause of the invention of pottery. While there seems to be little evidence of this, it is easy to conjecture that when water was needed to be heated in a basket, a ma.s.s of clay would be put on the bottom of the basket before it was put over the coals of fire. After the cooking was done, the basket could easily be detached from the clay, leaving a hard-baked bowl. This led to the suggestion of making bowls of clay and baking them for common use. Others suggest that the fact of making holes in the ground for cooking purposes gave the suggestion that by the use of clay a portable vessel might be made for similar purposes.

{92}

The economic value of cooking rests in the fact that a larger utility comes from the cooked than from the raw food. Though the phenomena of physical development of tribes and nations cannot be explained by the chemical const.i.tuents of food, although they are not without a positive influence. Evidently the preparation of food has much to do with man's progress, and the art of cooking was a great step in advance. The better utilization of food was a time-saving process--and, indeed, in many instances may have been a life-saving affair.

_The Domestication of Animals_.--The time and place of the domestication of animals are not satisfactorily determined. We know that Paleolithic man had domesticated the dog, and probably for centuries this was the only animal domesticated; but it is known that low forest tribes have tamed monkeys and parrots for pets, and savage tribes frequently have a band of dogs for hunting game or guarding the hut. While it may be supposed that domestication of animals may have occurred in the prehistoric period, the use of such animals has been in the historic period. There are many evidences of the domesticated dog at the beginning of the Neolithic period. However, these animals may have still been nearly half wild. It is not until the period of the Lake Dwellings of Switzerland that we can discriminate between the wild animals and those that have been tamed. In the Lake Dwelling debris are found the bones of the wild bull, or _urus_, of Europe. Probably this large, long-horned animal was then in a wild state, and had been hunted for food. Alongside of these remains are those of a small, short-horned animal, supposed to have been domesticated. Later, though still in the Neolithic period, remains of short-horned tame cattle appear in the refuse of the Lake Dwellings. It is thought by some that these two varieties--the long-horned _urus_ and the short-horned domesticated animal brought from the south--were crossed, which gave rise to the origin of the present stock of modern cattle in central Europe. Pigs and sheep were probably domesticated in Asia {93} and brought into Europe during the later Neolithic or early Bronze period.

The horse was domesticated in Asia, and Clark Wissler[1] shows that to be one great centre of cultural distribution for this animal. It spread from Asia into Europe, and from Europe into America. The llama was early domesticated in South America. The American turkey had its native home in Mexico, the hen in Asia. The dog, though domesticated very early in Asia, has gone wherever the human race has migrated, as the constant companion of man. The horse, while domesticated in Asia, depends upon the culture of Europe for his large and extended use, and has spread over the world. We find that in the historic period the Aryan people everywhere made use of the domesticated goat, horse, and dog. In the northern part of Europe, the reindeer early became of great service to the inhabitants for milk, meat, and clothing. The great supply of milk and meat from domesticated animals added tremendously to the food supply of the race, and made it possible for it to develop in other lines. Along with the food supply has been the use of these animals for increasing the clothing supply through hides, furs, skins, and wool. The domestication of animals laid the foundation for great economic advancement.
