The aim of the course is to reconstruct the historical-conceptual framework and the epistemological, anthropological, and ethical-political implications of the gender category and its connections with the concepts of sex, body, and identity in the philosophical work of Judith Butler, the most renowned and influential theorist of gender/post-gender/queer studies. The reading of the introductory text by Enrico Redaelli, Judith Butler. Il sesso e la legge (Feltrinelli, Milan 2023), and the analysis of Judith Butler’s texts, Undoing Gender (2004) and Notes Toward a Performative Theory of Assembly (2015), will aim to: 1) reconstruct the historical-philosophical context in which Judith Butler develops the gender category, connecting it to issues of sexual difference, power, and discursive order, starting from the theoretical framework of French deconstructivist and poststructuralist philosophy (Derrida, Deleuze, Foucault, Lacan); 2) grasp the epistemological, anthropological, and ethical-political implications of Butler’s deconstructivist and performative project.
