In this fascinating conversation we explore the history of liberal ideas from Alexis de Tocqueville and John Stuart Mills until today. Samuel Moyn is particularly interested in liberalism during the Cold War and the changes these ideas were subjected to during the battle of the ideologies. But we also explore how important theological traditions are for liberal thinking and how the philosophical principles underlying this broad current of ideas — freedom from oppression, emancipation, and human rights — can be revived in our current world.
