Supernatural etiologies of illness in Central Northern Borneo
Peter Metcalf (1982) examines the Berawan people of the lower Baram river system in Sarawak, central northern Borneo, arguing that their supernatural etiologies of illness function as a classification of causes of affliction rather than of diseases, which is precisely what enables their seamless coexistence with Western biomedical treatment. The article, based on fieldwork conducted between January 1972 and February 1974, is offered as a footnote to J.M. Elshout’s pioneer 1923 study of Kenyah-Dyak medicine and religion in central Borneo.
Summary
Metcalf’s central analytical move is to distinguish between etiologies of disease and etiologies of affliction. The Berawan do not theorise about the physical mechanisms by which a given symptomology develops; instead, their supernatural system addresses the question of why a particular person becomes afflicted at a particular time. This is why the community shows little resistance to government health education on vectors and hygiene: the two explanatory frameworks operate at different levels and do not compete. Mild, common complaints (fungal skin infections, tropical ulcers, stomach upsets from spoiled food) are attributed to purely physical causes and require no supernatural explanation. Serious accidents and difficulties in childbirth immediately suggest breach of taboo. Serious illness may have either of these causes or may result from soul loss, and in practice diagnoses often become complicated, with multiple etiologies cited simultaneously.
The article devits considerable attention to the mechanism of states of ritual danger, which follow automatically upon breach of taboo (nileng). The term nileng carries a dual meaning—both “taboo” and “pregnant”—and Metcalf argues this is no coincidence: the tabus are conceived as part of the natural order, operating with the inevitability of a pregnant state. Breach does not produce immediate retribution but places the offender in a condition of heightened vulnerability. Four named states exist (sijang, padju, tulah, parit), each associated with specific triggering acts and, in some cases, characteristic outcomes. The most common state, pale, can account for almost any affliction, and difficulty in childbirth is almost invariably attributed to it. The only recourse for pale is direct appeal to the Creator Spirit, Bik’Ngaputong, through the construction of a shrine and prayer; no shamanic intervention can lift it.
The third and most elaborately developed etiology is soul loss, which Metcalf identifies as the single most important cause of illness in the Berawan view. It is the most frequently cited, the most likely to produce fatal outcomes, and the one for which the most complex battery of defences exists—namely, shamanism. Metcalf describes two contrasting shamanic styles in detail: SadzMiri, a woman in her late fifties whose seances involve full trance, multiple spirit personae, dance, and song, and who functions as a classical psychopomp; and Tama Ukat Sageng, who remained fully conscious during performances, conversed with the audience, and relied on a single great spirit (bik’kijz). Beyond these individual styles, a host of specialised curing rituals and apparatus (spirit houses, swings, boats, vine barriers) are deployed for specific purposes, including the quarantine of entire communities during cholera epidemics. Metcalf notes that the centrality of the soul-loss doctrine leaves little room for witchcraft, which would locate the source of evil within human society rather than among anonymous spirits.
Key Findings
- The Berawan number approximately 1,600 people divided between four longhouse communities, two on the Tutoh river and two on the Tinjar, both tributaries of the Baram in Sarawak’s Seventh Division (p. 124, n.1).
- The ratio of shamans to population in the two intensively studied communities was approximately fifty people per daiyung, a rate Metcalf notes compares favourably with general practitioners in Western society (p. 121).
- Four named states of ritual danger exist—sijang, padju, tulah, parit—each triggered by specific acts; sijang is particularly associated with attack by dangerous wild animals (crocodile, snake, bear), while pale is the most common and can account for virtually any affliction (pp. 118–119).
- The pregnancy tabus (nileng) fall into two symbolic classes: acts that symbolically stop up the birth canal (tying, nailing, damming, driving poles into mud) and acts involving animals with anthropomorphic characteristics that might be transferred to the child (lizards, bears, thrashing fish) (pp. 117–118).
- The only ritual recourse for pale is direct appeal to the Creator Spirit Bik’Ngaputong through shrine construction and prayer; no shamanic intervention can lift this state, distinguishing it from sijang, which a shaman can address by offering carved substitute figures (p. 119).
- Vine barriers (rerng) were employed in the past to quarantine entire communities during deadly cholera epidemics that periodically swept through the area (p. 123).
Conclusion
Metcalf’s definitive historical takeaway is that the Berawan etiological system remains fully operative alongside Western biomedicine precisely because it classifies causes of affliction rather than diseases. As the Berawan acquire a fuller understanding of microorganisms and disease-carrying vectors, it remains possible simultaneously to adhere to conceptions of soul loss and ritual danger. The system provides a culturally coherent answer to the universal problem of the origin of evil—misfortune comes from the malice of anonymous spirits that steal souls, and community members (the shamans) struggle to recover them—without requiring the rejection of physical causation.
Context
- Primary data derive from Metcalf’s fieldwork (January 1972–February 1974) among the Berawan of the lower Baram, supported by the National Science Foundation Foreign Area Fellowship Program and the Wenner-Gren Foundation, under the sponsorship of the Sarawak Museum (p. 124, n.1).
- The article positions itself explicitly as a footnote to Elshout’s 1923 monograph and engages with the comparative shamanism literature (Eliade 1964) and functionalist theory (Malinowski 1948; Turner 1968), contributing to the medical anthropology of Borneo by demonstrating how a supernatural aetiological framework can be structurally compatible with biomedicine.
