The Foucauldian approach of biopolitics has become popular in current development studies because it is considered fruitful for studying resistance, especially in developing countries. Studying social movements in post-colonial localities through the Foucauldian perspective, it is argued, makes it possible to conceptualise new kinds of resistant, critical subjectivities capable of challenging the dominant, neoliberal development paradigm. Although a valid argument from the perspective of theoretical discussion, viewed from the grassroots level it can be criticised for theoreticism and elitism, qualities that, as pointed out in postcolonial theory, characterise much of the Eurocentric social movement research. This article reflects on these themes by drawing on an empirical case study that explores resistance to neoliberal development in Kolkata, India, introducing also some critiques that the Foucauldian approach has encountered. Based on critiques presented by both South Asian scholars and social movement activists, the article highlights problems in Western theory and knowledge production, while discussing the possibility of crafting genuinely movement-relevant theories of resistance that transcend the separation between theory and practice.
