the brain with lines drawn to show how far upward the social_ life of man has already progressed and how much more of the higher faculties of the brain remains for us to bring into dominance before we can reach the top and crown in the great archetype of society.
In the full-page Chart of Historic Growth we have supplied such a chart of the brain, mapping out the past history of man with as much detail as the size of the engraving will admit. The middle band, or phase of youth, is shaded by stippling.
In the study of this chart we shall learn that six great forms of civilization have thus far been masters of the world. These were the Egyptian, Mongolian, Hindoo, Semitic, Graeco-Roman, and Christian. But each of these forms was fragmentary. Each of them was dominated or took its cast of character from only a limited region of the brain. It supplied only a part of the wants and aspirations of man. Other regions or faculties of the brain were more or less active but did not determine the national character or course of development.
A mere sketch of these past forms will serve our purpose. It will show their failures and will illustrate by contrast that coming and nobler civilization which is close before us, the age of Harmonism. A true study of evolution surveys the past in order to learn of the future.
EGYPTIAN CIVILIZATION commenced its massive and vigorous growth under the most favorable of external conditions. The mental power and susceptibility varies widely in different races of men. The capacity to develop a civilization is only moderate in some while it is very great in others, just as in some
