Book excerpt: Sarah Kane was one of the landmark playwrights of 1990s Britain, her influence being felt across UK and European theatre. This is the first book to focus exclusively on Kane's unique approach to mind and mental health. It offers an important re-evaluation of her oeuvre, revealing the relationship between theatre and mind which lies at the heart of her theatrical project. Drawing on performance theory, psychoanalysis and neuroscience, this book argues that Kane's innovations generate a 'dramaturgy of psychic life', which re-shapes the encounter between stage and audience. It uses previously unseen archival material and contemporary productions to uncover the mechanics of this innovative theatre practice. Through a radically open-ended approach to dramaturgy, Kane's works offer urgent insights into mental suffering that take us beyond traditional discourses of empathy and mental health and into a profound rethinking of theatre as a mode of thought. As such, her theatre can help us to understand debates about mental suffering today.
