For two decades, Melanesianists have sought to reconcile what Robert Foster (1995) termed the 'New Melanesian History' and the 'New Melanesian Ethnography'. The former describes historically oriented studies that critique representations of Melanesian custom as recent objectifications of strategically positioned discourses and practices. The latter describes culturally oriented, particularist studies that characterize Melanesian sociality as an undifferentiated plane of being without integral a priori units; on every scale, human agency must individuate persons and collectivities by means of 'fraction', 'de-conception', and 'decomposition'. In this article I present data from Solomon Islands that resist analysis in terms of an unqualified both/and synthesis of these orientations. Specifically, I argue that articulations of matrilineal connections to land among the Arosi of Makira are neither merely postcolonial reifications of custom nor historically conditioned 'depluralizations' from an always pre-constituted social pleroma. Through historically situated case studies, I show how Arosi land disputes both reproduce and revalue matrilineally defined categories, each understood as the humanized continuation of an autonomous primordial essence. Recognition of the continuing importance of these categories among Arosi highlights what the New Melanesian Ethnography has obscured: that some Melanesians confront a historically transforming problem of how pre-existent parts fit together to make up social totalities.
2In a series of publications with significant comparative implications for Oceanist anthropology, Edvard Hviding (1993, 1996 Sometimes, he reports, Marovo people put these attenuated unilineal models into practice in ways that bar whole sets of bilateral kindred from claims to marine and land rights that might otherwise find support in the broader category of butubutu. At other times, he argues, they debate competing unilineal constructions of their customary land tenure and strategically play them against one another to frustrate resource extraction they do not want.
