本文以臺東縣海端鄕霧鹿聚落和南投縣仁愛鄕古古安聚落的民族誌爲基礎， 探討布農人對於疾病的分類與形成原因的看法、治療的過程及其效力（efficacy) 的來源以及治療儀式與其人觀的關係。過去對布農人巫術與治療儀式的主要硏究， 均將這些視爲孤立的、自成一格的體系，而忽略相關的社會文化過程與脈絡；同 時，也偏重於靜態的描述而缺少分析。因此，本文除了闡明布農人對疾病與醫療 的文化觀念之外，更進一步從當代布農族巫師所面臨的困境，來探討在歷史變遷 的過程中，外在的政治與宗敎力量對布農人原有醫療傳統的影響和重新界定，以 及布農人對於這些改變和衝擊是如何地理解與回應。

This article investigates indigenous healing practices among the Bunun, an Austronesian-speaking aboriginal people of Taiwan. Etiology, classification of illness, the procedures of healing rituals, and their efficacy are examined in relation to Bunun concepts of personhood. Previous studies of Bunun spirit mediumship and ritual healing treat them as a bounded, isolated system and ignore socio-cultural processes and contexts. At the same time, these studies provide static and at times fragmentary descriptions but little analysis. Thus, this article not only aims to illuminate Bunun cultural notions concerning illness and its cure, but also to situate Bunun spirit mediumship in the context of social change. The article illustrates how external political and religious forces influence and redefine Bunun healing traditions’ as well as how the Bunun understand and respond to these forces. It is suggested that Bunun spirit mediumship is not only a way of dealing with spirits and curing ailments, but also a way of contemplating their own position in the contemporary world.
