Elgar Advanced Introductions are stimulating and thoughtful introductions to major fields in the social sciences, business and law, expertly written by the world's leading scholars. Designed to be accessible yet rigorous, they offer concise and lucid surveys of the substantive and policy issues associated with discrete subject areas.This original Introduction presents nationalism as the most important social force shaping the ways modern people live their lives. It explains the formative influence of nationalism in the public spheres of politics and the economy, as well as the most private ones of emotional wellbeing and mental illness. Along the way, it illuminates widely used but rarely clarified concepts, such as social institution, revolution, ideology, and totalitarianism, and introduces new ones, like dignity capital, and nationalism as the double-helix of modern politics. Basing its conclusions on over 25 years of original comparative historical research, this book bears the characteristic Liah Greenfeld imprint: fact-based discussion, logical rigor, unexpected connections, and an exceptionally wide range of issues woven together to explain the way we live now.Key features include: • discusses nationalism as an empirical phenomenon, not an object of speculation• distils findings of over 25 years of original comparative historical research• introduces original concepts of dignity capital and nationalism as the double-helix of modern politics.
