This book explores the pedagogical possibilities of testimony and witnessing. Drawing on the work of Giorgio Agamben, this book highlights the ultimate impossibility of witnessing and testimony: testimonies do not stand outside language, history, politics, or capitalist systems. Through analysis of different aspects of representation, subjectivity and emotions, this book illustrates how testimonies can be used as a way to control student emotions, perceptions and understandings. Testimonies used within teaching can work as a way to reproduce stereotypes of suffering, and can thus consolidate and reinforce exisiting power structures and identities. By exploring these difficulties, the author argues for the value of teaching historical testimonies of suffering that recognize both the impossibilities and possibilities of witnessing and testimony.
