The notions of happiness and trust as cements of the social fabric and political legitimacy have a long history in Western political thought. However, despite the great contemporary relevance of both subjects, and burgeoning literatures in the social sciences around them, historians and historians of thought have, with some exceptions, unduly neglected them. In Trust and Happiness in the History of European Political Thought, editors László Kontler and Mark Somos bring together twenty scholars from different generations and academic traditions to redress this lacuna by contextualising historically the discussion of these two notions from ancient Greece to Soviet Russia. Confronting this legacy and deep reservoir of thought will serve as a tool of optimising the terms of current debates. Contributors are: Erica Benner, Hans W.
