The introduction to The Palgrave Handbook of Radical Theology describes the importance of this book in the study of radical theology. It explains the editors’ decision to organize the book in three sections: introductory and background material, major figures in radical theology, and topics of interest to radical theology. This book also takes care to investigate some forgotten figures and novel topics in radical theological history. The editors also acknowledge the racism and elitism in the tradition and its neoliberalization in recent years. They describe these developments as a mistake and emphasize radical theology’s potential.
