The book compares
East and
West across the last 15,000 years, arguing that
physical geography rather than culture, religion, politics,
genetics, or
great men explains Western domination of the globe. Morris' Social Development Index considers the amount of energy a civilization can usefully capture, its ability to organize (measured by the size of its largest cities), war-making capability (weapons, troop strength, logistics), and information technology (speed and reach of writing, printing, telecommunication, etc.). The evidence and statistical methods used in this book are explained in more detail in
Social Development, a free eBook, and by the published volume,
The Measure of Civilization. Morris argues that: • When
agriculture was first invented, areas with reliable rainfall benefited most. • Irrigation benefited drier areas such as Egypt and the Fertile Crescent. • Plants and animals that were more easily
domesticated gave certain areas an early advantage, especially the
Fertile Crescent and China. (See
cradle of civilization.) Development of Africa and the Americas started on the same path, but it was delayed by thousands of years. • With the development of ships in Eurasia, rivers became trade routes. Europe and empires in Greece and Rome benefited from the Mediterranean, compared to Chinese empires (who later built the
Grand Canal for similar purposes). • Raids from the
Eurasian Steppe brought diseases that caused epidemics in settled populations. • The Social Development Index shows the West leading until the 6th century, China leading until the 18th century, and the West leading again in the modern era. • After the development of ocean-going ships, the significantly greater size of the Pacific Ocean made trans-Atlantic exploration and trade more feasible and profitable for Europe than trans-Pacific exploration and trade for East Asia. Though the
mariner's compass was invented in China in the 11th century,
Chinese exploration was less successful than the European
Age of Discovery and subsequent colonization. • Eurasian diseases to which people in the Americas had no immunity were a byproduct of Eurasian development that devastated Native Americans after contact, in addition to superior European weapons. •
Globalization and advances in information technology are leveling differences between civilizational areas. ==Reception==
