Book excerpt: This volume delves into the question of how, in an Iberian world apparently far removed from the battlegrounds of modernity and secularisation, doubt and unbelief found fertile soil, stimulated by social and religious developments. Adopting a multidisciplinary perspective, the contributors show how the crisis of identity produced by forced mass conversion touched off inner crises about the nature of Truth. By tracing the path from medieval Spain to the Spanish Inquisition, and from the great literary and artistic works of the Spanish Baroque to Sephardic Marranism, this volume fills a historiographical gap in European social and intellectual history, demonstrating the importance of the Iberian world in the evolution of European scepticism. Mercedes García-Arenal is Research Professor at CSIC, Madrid, and Stefania Pastore is Associate Professor at the Scuola Normale Superiore di Pisa. They work on tolerance and dissent in Early Modern Iberia: on forced conversion, on the violent world of the Inquisition and the debates and protests that it sparked, and on the complex interplay of minorities. They have recently collaborated on After Conversion. Iberia and the Emergence of Modernity (Brill, 2016) and, as editors, Visiones imperiales y profecía. Roma, España, Nuevo Mundo (Abada, 2018).
