Concepts exist to organise and explain the world, but they often disintegrate in the face of reality. Take the bombings in Boston: we’ve talked abstractly about “globalisation” for 30 years, but events like this show just how viciously complicated a globalised world can be. Tracing Tamerlan and Dzhokar Tsarnaev’s toxic resentments sends us careening from Chechnya’s conflicts with Russia, to the opaque interplay between fundamentalism and a liberal society, and then abruptly off the grid into radicalised digital media. What concept could possibly help us follow this dizzying path? Certainly, ideas like Tom Friedman’s “flat earth” and “super-empowered individual” appear less than satisfying explanations of the world we now inhabit.
David Armitage’s Foundations of Modern International Thought might not seem, at first glance, to have much to say about these problems: it’s an academic book about a developing field and it makes no immediate claims for its own relevance. But Armitage’s approach is both groundbreaking as history and relevant to our collective situation, because what he’s engaged in is the historian’s project at its most ambitious and rewarding. He is trying to change the way we think about our world by going backwards—to the origins of globalisation—and showing how much we’ve forgotten since.
