As part of Benjamin Constant's academic “revival,” scholars have revisited the political and religious elements of his thought, but conclude that he remained uninterested in the nineteenth century's major social and economic questions. This article examines Constant's response to what would later become known as “the social question” in his Commentary on Filangieri's Work, and argues that his claims about poverty and its alleviation highlight central elements of his political liberalism, especially on the practice of citizenship in the modern age. By interpreting social issues through his original political lens of “usurpation,” Constant encouraged skepticism of social legislation and identified the political implications of a “disinherited” poor class. The lens of usurpation ultimately limited the scope of Constant's solutions to poverty. But his attention to social and economic issues prompts us to reexamine the category of “the social” and its uses in the history of liberal thought, particularly the place of class concerns in the French liberal tradition.
