A timely call for recovering the true meanings of the nineteenth‐century terms that are hobbling current political debates "Masterful. . . . James cuts through the tangled terminological and conceptual jungle of modern globalist discourse . . . [with] fascinating discussions of the origins and meanings of the words."-G. John Ikenberry, Foreign Affairs "James delves into the often-surprising intellectual origins of key concepts in the arguments about globalisation-and illuminates the debate in the process."-Gideon Rachman, Financial Times, "Best Books of 2021: Politics" Nationalism, conservatism, liberalism, socialism, and capitalism are among the most fiercely debated ideas in contemporary politics. Since these concepts hark back to the nineteenth century, much of their nuanced meaning has been lost, and the words are most often used as epithets that short-circuit productive discussion. In this insightful book, Harold James uncovers the origins of these concepts and examines how the problematic definition and meaning of each term has become an obstacle to respectful communication. Noting that similar linguistic misunderstandings accompany such newer ideas as geopolitics, neoliberalism, technocracy, and globalism, James argues that a rich historical knowledge of the vocabulary surrounding globalization, politics, and economics-particularly the meaning and the usefulness that drove the original conceptions of the terms-is needed to negotiate the gaps between different understandings and make fruitful political debate once again possible.
