Concepts of development are inevitably loaded with value judgements concerning what constitutes ‘proper’ social and economic organisation. Focusing on the cultural politics of development on Siquijor, an island in the Central Visayas region of the Philippines, this paper explores these often tacit ideals. It considers one of the key idioms Siquijodnon use in explaining how development is brought about—cooperation—and some of its locally perceived opposites—‘crab mentality’, politicking and corruption—which contain powerful moral critiques of self and society. On Siquijor, local discourses of development have it that widespread poverty in the Philippines demonstrates a failing of Filipinos to live up to supposedly universal norms of ethical socio‐economic conduct. However, I argue that attention to local norms of moral economy reveal the ambivalence underlying these notions of development, particularly in relation to the roles of individualism and reciprocity in socio‐economic organisation.
