Reads modernism and theory through Susan Sontag's archiveThis adventurous critical inquiry into Sontag's archive illuminates the intimate link between modernism and theory while also providing a fascinating reintroduction to these two movements and concepts. Mena Mitrano explores three core ideas in this study: the confusion of terms between modernism and theory; the concept of an 'unwritten theory' suggested by Sontag's subterranean engagement with the foremost theorists of our time (Derrida, Foucault, Deleuze, Lacan, Jameson and others) in the rawness of her journals and notebooks; and Sontag's identity as a non-traditional philosopher, through the extraordinary discipleship to Walter Benjamin. The book is driven by new archival research and will have a multi-layered impact, changing our perception of Sontag as a post-Cold War public intellectual as well as interrogating key concepts in the Humanities.
