It's quite easy to read and pretty interesting. The impression I got after reading it is that it supports the fact that civilization have in common at least two main characteristics two points quickly summarized in the rest of this article (not meaning to be original here).
- a unified vision of the world, expressed through religion (like Chinese cult of ancestries, Ancient Egyptians' common representation of life/death, day/night and east/west by the travel of Rê, or Native Americans perception that humans and animals where all sort of embodiments of spirits), through politics (the systematization of law and right by the Romans) or a bit of both (the role of Islam as a support for social control in societies that once where part of the Ottoman civilization).
- a persistence in time like with Chinese 2 thousand-year old writing system, the continuous influence of Egypt on Mediterranean and European civilizations and Europe's Roman legacy.
Another interesting side effect of the great civilization is apparently to offer great periods of peace (pax romana: 1st and 2nd century A.D, "Chinese peace": 2nd to 3rd century A.D. and "ottoman peace": 16th to 19th? century).
