This book discusses whether democracy and republicanism are identical, complementary, or contradicting ideas. The rediscovery of classic republicanism a few decades ago made it clear how profoundly modern notions of democracy had been shaped by the republican tradition. But defining these two concepts remains difficult, and the views diverge widely. The overarching aim of this book is to discuss the extent to which democracy and republicanism are identical, complementary or mutually contradicting ideals / ideas. Pursuing this open approach to the subject means calling into question a widely used formula according to which modern democracy is composed of liberal principles such as individualism, the rule of law and human rights, on the one hand, and of republican principles such as focusing on the common good and popular sovereignty, on the other. This book will appeal to students, researches, and scholars of political science interested in a better understanding of political theory and political history.
