The conceptualization of human agency is one of the oldest and most debated challenges in political theory. This essay defends the continuous relevance of this endeavour against a proliferating theoretical pessimism. Instead of engaging the much rehearsed structure-agency debate, the author conceptualizes agency in relation to discourses. However, such an approach inevitably elicits suspicion. Is discourse not merely a faddish term, destined to wax and wane with fleeting intellectual trends of the postmodern and poststructural kind? Does the concept of discourse, (...) as many fear, suck us into a nihilistic vortex and deprive us of the stable foundations that are necessary to ground our thoughts and actions? Not so, argues this essay, and defends an anti-essentialist stance as the most viable chance for retaining an adequate understanding of how people situate themselves as agents and influence their socio-political environment. The ensuing analysis, which focuses on everyday forms of resistance, demonstrates how the very acceptance of ambiguity, often misrepresented as relativism, is a crucial precondition not only for the conceptualization of human agency, but also for its actual application in practice.
