This week on The Learning Curve, guest cohost Jonathan Greenberg speaks with Loyola University Maryland professor and American Enterprise Institute senior fellow Dr. Diana Schaub. They discuss America’s democratic civic culture and how Enlightenment thinkers shaped the Founders’ views about modern republican self-government. Prof. Schaub explores the legacies, speeches, and writings of Abraham Lincoln and Frederick Douglass, and how knowledge of U.S. history and primary sources can debunk revisionist approaches to teaching history and civics. Dr. Schaub closes the interview with a reading from her recent book, His Greatest Speeches: How Lincoln Moved the Nation.
