Demonstrating his own power has been not only a necessary condition of Chagnon's fieldwork, but a main technique of investigation. In a scientific reprise of a losing military tactic, he also attempted to win the hearts and minds of the people by a calculated redistribution of material wealth, and in so doing, managed to further destabilize the countryside and escalate the violence. Tierney quotes a prominent Yanomami leader: "Chagnon is fierce. Chagnon is very dangerous. He has his own personal war." Meanwhile, back in California a defender of Chagnon in the e-mail battles has lauded him as "perhaps the world's most famous living social anthropologist." The Kurtzian narrative of how Chagnon achieved the political status of a monster in Amazonia and a hero in academia is truly the heart of Darkness in El Dorado. While some of Tierney's reporting has come under fire, this is nonetheless a revealing book, with a cautionary message that extends well beyond the field of anthropology. It reads like an allegory of American power and culture since Vietnam.
