This is the first survey of Murdoch’s exploration of evil, addressing aesthetic, philosophical, political and theological perspectives.The study demonstrates how her work engages with currently urgent issues of trauma, terrorism and psychopathy and brings her works into dialogue with key figures in twentieth- and twenty-first-century discussions of evil, including Hannah Arendt, Carl Gustav Jung, Susan Neiman and Simone Weil.These resonances are traced through close readings of Murdoch’s published fiction and philosophy in combination with unpublished texts, including annotations, interviews and letters.Murdoch’s detailed and nuanced portrayal of evil invites readers to explore the complexities of human behaviour and the potential for moral failure.
