This edited volume examines the critical issues of the 21st century through the prism of Ernest Gellner’s work. The contributors look critically at Gellner´s legacy, questioning whether he remains an inspiration for today’s social theorists. Chapters proactively probe Gellner’s thoughts on a variety of pressing topics—modernity, postcolonialsm, nationalism, and more—without losing sight of current debates on these issues. This volume further brings these debates to life by having each chapter followed by a comment by an academic peer of the chapter author, thus transforming the text into a lively and dynamic conversation.
