[28] The idea of such boundaries resembles the "traditional view of social norms and obligations" that Thompson defines as a moral economy (E. P. Thompson, "The Moral Economy of the English Crowd in the Eighteenth Century," Past and Present 50 [February 1971]: 76-136). Because the term "traditional" implies that the moral economy is static, the norms and obligations fixed, I find Sabean's formulation more useful to describe agreements over boundaries: "Members of a community are engaged in the same argument, the same raisonnement , the same Rede , the same discourse, in which alternative strategies, misunderstandings, conflicting goals and values are threshed out" (Power in the Blood , p. 29).
