ism is known to have preceded civilization. The history of the human race is one in source, one in experience, one in progress.
It is both a natural and a proper desire to learn, if possible, how all these ages upon ages of past time have been expended by mankind; how savages, advancing by slow, almost imperceptible steps, attained the higher condition of barbarians; how barbarians, by similar progressive advancement, finally attained to civilization; and why other tribes and nations have been left behind in the race of progress—some in civilization, some in barbarism, and others in savagery. It is not too much to expect that ultimately these several questions will be answered.
Inventions and discoveries stand in serial relations along the lines of human progress, and register its successive stages; while social and civil institutions, in virtue of their connection with perpetual human wants, have been developed from a few primary germs of thought. They exhibit a similar register of progress. These institutions, inventions and discoveries have embodied and preserved the principal facts now remaining illustrative of this experience. When collated and compared they tend to show the unity of origin of mankind, the similarity of human wants in the same stage of advancement, and the uniformity of the operations of the human mind in similar conditions of society.
Throughout the latter part of the period of savagery, and the entire period of barbarism, mankind in general were organized in gentes, phratries and tribes. These organizations prevailed throughout the entire ancient world upon all the continents, and were the instrumentalities by means of which ancient society was organized and held together, Their structure, and relations as members of an organic series, and the rights, privileges and obligations of the members of the gens, and of the members of the phratry and tribe, illustrate the growth of the idea of government in the human mind. The principal institutions of mankind originated in savagery, were developed in barbarism, and are maturing in civilization.
