[113]-131) and index.Introduction -- Reason and ethos -- After critique: affirming subjectivity -- Animating the reach of our moral imagination -- Democracy's predicament -- Conclusion.In The Ethos of a Late-Modern Citizen, Stephen K. White contends that Western democracies face novel challenges demanding our reexamination of the role of citizens. White argues that the intense focus in the past three decades on finding general principles of justice for diversity-rich societies needs to be complemented by an exploration of what sort of ethos would be needed to adequately sustain any such principles. Accessible, pithy, and erudite, The Ethos of a Late-Modern Citizen will appeal to a wide audience.CitizenshipCitizenship.323.601White Stephen K261168MiAaPQMiAaPQMiAaPQBOOK9910785169603321The ethos of a late-modern citizen3699882UNINA
