Lorenzini elucidates Foucault’s lifelong project of a history of truth, situates Foucault’s late analysis of parrhesia within that project, and demonstrates how this yields a different understanding of Foucault’s genealogical critique. Along the way, he argues vehemently against readings of Foucault that turn him into a relativist and against Nancy Fraser’s and Jürgen Habermas’ criticism that Foucault’s critique lacks normative foundations.
