The social order of the family and the state slowly appeared. Man became a co-operating creature, working with his fellows in the satisfaction of material wants and in protecting the rights of individuals. Slow and painful was this process of development, but as he worked his capacity enlarged, his power increased, until he mastered the forces of nature and turned them to serve him; he accumulated knowledge and brought forth culture and learning; he marshalled the social forces in orderly process. Each new mastery of nature or self was a power for the future, for civilization is cumulative in its nature; it works in a geometrical progression. An idea once formed, others follow; one invention leads to another, and each material form of progress furnishes a basis for a more rapid progress and for a larger life. The discovery and use of a new food product increased the power of civilization a hundredfold. One step in social order leads to another, and thus is furnished a means of utilizing without waste all of the individual and social forces. Yet how irregular and faltering are the first steps of human progress. A step forward, followed by a long period of readjustment of the conditions of life; a movement forward here and a retarding force there. Within this irregular movement we discover the true course of human progress. One tribe, on account of peculiar advantages, makes a special discovery, which places it in the ascendancy and gives it power over others. It has obtained a favorable location for protection against oppressors or a fertile soil, a good hunting ground or a superior climate. It survives all opposing factors for a time, and, obtaining some idea of progress, it goes on adding strength unto strength, or is crowded from its favorable position by its warlike neighbors to perish from the earth, or to live a {9} stationary or even a deteriorating life. A strong tribe, through internal development and the domination of other groups, finally becomes a great nation in an advanced state of civilization. It passes through the course of infancy, youth, maturity, old age, and death. But the products of its civilization are handed on to other nations. Another rises and, when about to enter an advanced state of progress, perishes on account of internal maladies. It is overshadowed with despotism, oppressed by priestcraft, or lacking industrial vitality to such a degree that it is forced to surrender the beginnings of civilization to other nations and other lives.
