“Kevin Ingram’s tour de force, this book is original, persuasive and controversial; demonstrating the determining influence of converso nonconformity on the culture and society of early modern Spain with an argument that moves far beyond the sterile shadow of the debate between Américo Castro and Claudio Sánchez-Albornoz … . there can be no doubt that the material uncovered in this book has profound implications for our understanding of the Counter-Reformation in Spain, as well as the religious history of Europe in the age of confessionalisation.” (Alexander Samson, Journal of Ecclesiastical History, Vol. 72 (3), 2021)“Making these ideas accessible again through the new edition of this book, for which Viktor Sarris deserves thanks and appreciation, should be a contribution to the enrichment of our science of thinking and problem solving today, but above all an encouragement to every reader to take the risk and the pleasures of productive thinking in every day life.” (Gerhard Stemberger, Gestalt Theory, Vol. 43 (2), 2021)
