Abstract: In popular thought about the meaning of religion, as well as established debates in anthropology, religious belief is interpreted as either a commitment to a clear set of propositions, or as a non-literal, symbolic, ethical or social commitment. Anthropologists have tended to support the latter of these positions, so much so that this can now be seen as the ‘anthropological’ position; it is also characteristic of the view of scholars in related disciplines, such as religious studies. This article argues for a third possibility: that religious (and other) believers are often engaged in complex, reflexive practices that stipulate specific cognitive and non-cognitive relationships to propositional content. This is demonstrated with reference to contemporary Buddhism in Inner Mongolia, China. The author argues that the existence of such cultures of belief demonstrates there is a need for a systematic anthropological theory of belief and suggests some sources that may contribute to its formulation
