Spiritual and natural etiologies on a Polynesian outlier in Papua New Guinea

Several writers have challenged recently the long-held contention that non-Western peoples tend to emphasize spirits, sorcerers, and other supernatural forces in their explanations for the cause of illness. Here, I examine indigenous theories of illness-causation on Nukumanu, a Polynesian outlier atoll in Papua New Guinea. Although Nukumanu invoke mundane as well as supernatural explanations, their major preoccupation is with spirits as etiological agents. In this light, I suggest a number of potential reasons for the difference between my findings on Nukumanu and those of commentators who have emphasized naturalistic etiologies among the peoples they have studied. In addition to real ethnographic variation, I argue that a major reason for the difference lies in the level of causality (instrumental as opposed to efficient and ultimate) sought by various investigators.
