“There was no money economy in Egypt, and all exchange of goods was carried out by barter. Each citizen paid a tax in kind of everyt5hing he produced, and the wealth of the pharaoh thus consisted of the grain, livestock, and other goods that he took as taxes. He also received metals and other goods as tribute or in trade from abroad.”

“The end of Egypt's isolation turned what had been only occasional and incidental contact with the rest of the Near East into a constant and significant exchange of goods and ideas. The new cosmopolitanism introduced new forms and motifs and a growing naturalism to art. Egypt had always been receptive to immigrants, who had easily been assimilated into its culture; now even the pharaohs could marry foreigners. In addition, the increase of commerce and the emergence of a cosmopolitan urban population -- at Thebes and other cities -- marked the first real urbanization in Egyptian society.”

“The German economic historian Fanz Oertel in the 1950s points to another drastic consequence of a slave economy. A slave economy initially allowed an increase of productivity through the invention and use of new machinery. Roman products remained at a simple level and could be reproduced by handicraft. By the fourth century, for example, the robust pottery industry of Greece was in sharp decline because other parts of the empire also learned to make pottery."The decline in international trade in the Mediterranean in the fourth century was partly due to increasing piracy, but it was also due to lack of industrial innovation and of need for exchange of manufactured goods.”

“Egypt was rich in copper ore, which, as the base of bronze, had been valuable through the entire Meditarranean world. By 1150 B.C., however, the Iron Age had succeeded the bronze Age. Egypt had no iron and so lost power in the Asiatic countries where the ore existed; the adjustment of its economy to the new metal caused years of inflation and contributed to the financial distress of the central government. The pharaoh could not meet the expenses of his government; he had no money to pay the workers on public buildings, and his servants robbed him at every opportunity. Still a god in theory, he was satirized in literature and became a tool of the oligarchy. During the centuries after the twelfth B.C., the Egyptian state disintegrated into local units loosely connected by trade. Occasional spurts of energy interrupted the decline, but these were short-lived and served only to illuminate the general passivity.”

“The availability of irrigation systems to water the land and produce grain and other food crops was the material foundation for these two great river-valley societies, Egypt and Iraq. They were hydraulic despotisms, in which a small ruling class, with the aid of soldiers and priests, commanded the material resources that gave sustenance to these civilizations and allowed them to build cities, palaces, and tombs.”

“[Egyptian] advances in medicine, however, as well as in other areas of science, were limited to their attempts to solve the problems confronting them. They did not attempt to probe into the realm of theory."History for the Egyptians was the cyclic recurrence of the elements of the divine eternal order. Just as the land was reborn each year, so the pharaoh who died and became Osiris was reborn in Horus, his son and successor. The passage of time was marked by the succession of pharaohs, who were grouped into dynasties and numbered.”

“The Gnostics (also called Manichees) postulated that there were two gods -- the Christian God of goodness and light, and an evil anti-God of darkness. This theory proved an easy explanation of why there was evil in the world. It was rejected by Catholic Christianity in favor of the monotheistic view that there was one God who created only goodness. Evil was sin, a rebellious falling-away from God, a perversion of His goodness. This was the foundation of the evolving Christian concept of Satan.”
