Recovery from disaster is a long process, as this Museum of Anthropology exhibition demonstrates. Open until Sept. 19. “Anagnorisis” is Greek for “learning upward” — the sudden shock when we finally see and understand what’s really going on. I had such shocks on almost every page of this very important new book. This is a long review because the book raises very many issues rarely mentioned in medical or political history. It calls into question not only our global health system, but the economic and political systems that pretend to support it. Alex de Waal is the executive director of the World Peace Foundation at The Fletcher School of Law and Diplomacy and professorial fellow at the London School of Economics. He is an expert on the politics of Sudan and the Horn of Africa, and the author of seven previous books on Africa, AIDS and famine. He is also writing sharp analysis of the war in Tigray that attracts a lot of critics on Twitter.
