This article explores mundane political agency. We introduce the notion of the political ordinary as agency based on the capacity of human beings to carry out acts that are undetermined and unexpected, and thus capable of challenging, opposing, negotiating, maintaining, and readjusting prevailing conditions. We approach subjectivity from a pragmatist and phenomenological point of view and argue that it is the condition of possibility of political agency. The paper demonstrates how political subjectivity can be located in the ways in which people take up issues that stand out as important to them. To this end, we look into the everyday life experiences of an eleven-year-old girl whose struggles related to proposed subject positions provide examples of mundane political agency. We conclude by arguing that political agency is the subject’s action when in a state of becoming prompted by future-oriented demands and contingencies of social life.
