Hanna Pitkin has made key contributions to the field of political philosophy, pushing forward and clarifying the ways that political theorists think about action as the exercise of political freedom. In so doing, she has offered insightful studies of the problems of modern politics that theorists are called to address, and has addressed them herself in a range of theoretical genres. She is an innovator in bringing conceptual work inspired by ordinary language philosophy to the field of political philosophy, as well as a penetrating and exacting interpreter of texts who draws on the insights of psychoanalysis, gender, and historical study. This collection of her works approaches each of these dimensions of Pitkin's contributions in turn, recognizing that she typically blends these modes of engagement in much of her political theorizing.
