In recent decades, some feminists have turned to the writings of Hannah Arendt in order to propose a truly emancipatory ethic of care or to find the principles that could lead to the political institutionalization of care. Nevertheless, the feminist interpretations of Hannah Arendt are particularly contrasted. According to Sophie Bourgault, this recourse to Hannah Arendt is deeply problematic, mainly because of her strong distinction between the private and public spheres. This article discusses the relevance of using Arendt’s concepts to think about the institutionalization of care by Joan Tronto. Indeed, the most recent analyses developed on the politics of care are shaped by Arendt’s concepts such as power, amor mundi or by her conception of politics as a relationship.
