These early civilisations are merely the highest point of Neolithic culture. The Egyptian remains show a very gradual development of pottery, ornamentation, etc., into which copper articles are introduced in time. The dawn of civilisation is as gradual as the dawn of the day. The whole gamut of culture--Eolithic, Palaeolithic, Neolithic, and civilised--is struck in the successive layers of Egyptian remains. But to give even a summary of its historical development is neither necessary nor possible here. The maintenance of its progress is as intelligible as its initial advance. Unlike China, it lay in the main region of human development, and we find that even before 6000 B.C. it developed a system of shipping and commerce which kept it in touch with other peoples over the entire region, and helped to promote development both in them and itself. Equally intelligible is the development of civilisation in Mesopotamia. The long and fertile valley which lies between the mountainous region and the southern desert is, like the valley of the Nile, a quite recent formation. The rivers have gradually formed it with their deposit in the course of the last ten thousand years. As this rich soil became covered with vegetation, it attracted the mountaineers from the north. As I said, the earliest centre of the civilisation which was to culminate in Babylon and Nineveh is traced at Susa, on the hills to the north, about 6000 B.C. The Akkadians (highlanders) or Sumerians, the Turanian people who established this civilisation, descended upon the rivers, and, about 5000 B.C., set up the early cities of Mesopotamia. As in the case of Egypt, again, more tribes were attracted to the fertile region, and by about 4000 B.C. we find that Semitic tribes from the north have superseded the Sumerians, and taken over their civilisation. In these ancient civilisations, developing in touch with each other, and surrounded by great numbers of peoples at the high Neolithic level from which they had themselves started, culture advanced rapidly. Not only science, art, literature, commerce, law, and social forms were developed, but moral idealism reached a height that compares well even with that of modern times. The recovery in our time of the actual remains of Egypt and Babylon has corrected much of the libellous legend, which found its way into Greek and European literature, concerning those ancient civilisations. But, as culture advances, human development becomes so complex that we must refrain from attempting to pursue, even in summary, its many outgrowths. The evolution of morality, of art, of religion, of polity, and of literature would each require a whole volume for satisfactory treatment. All that we can do here is to show how the modern world and its progressive culture are related to these ancient empires.
