Adapting the United Nations’ approach for measuring human development, Morris’s index breaks social development into four traits—energy capture per capita, organization, information technology, and war-making capacity—and he uses archaeological, historical, and current government data to quantify patterns. Morris reveals that for 90 percent of the time since the last ice age, the world’s most advanced region has been at the western end of Eurasia, but contrary to what many historians once believed, there were roughly 1,200 years—from about 550 to 1750 CE—when an East Asian region was more advanced. Only in the late eighteenth century CE, when northwest Europeans tapped into the energy trapped in fossil fuels, did the West leap ahead.
