I had arrived in Haiti to investigate zombis. A poison had been found and identified, and a substance had been indicated that was chemically capable of maintaining a person so poisoned in a zombi state. Yet as a Western scientist seeking a folk preparation I had found myself swept into a complex worldview utterly different from my own and one that left me demonstrating less the chemical basis of a popular belief than the psychological and cultural foundations of a chemical event. Perhaps more significantly, the research had suggested that there was a logical purpose to zombification that was consistent with the heritage of the people.
