The Eberstadt piece on AIDS, with its staggering, horrifying numbers, can’t help but provoke serious thought. Reading it, I was reminded how precious and fragile are our civilization and our prosperity, and how terrifying and humbling are the mysteries of life and death. The denial in which the leaders of the great Eurasian powers seem to be living is alarming, as is the dearth of public health research on the behaviors that spread the epidemic. At the end of the Cold War, three paradigms competed to make sense of the world–-democratization, clash of civilizations, and anarchy–collapse. Sadly, the Eberstadt article shows that the chaos model is still very much alive.
