Seth Cotlar is a professor of history at Willamette University and the author of Tom Paine's America: The Rise and Fall of Transatlantic Radicalism in the Early Republic. He joins us to talk about Paine's particular vision of a more radical democracy and how those ideas find life in today's left. Cotlar is also hard at work on a new volume about the concept of nostalgia, obviously a favorite topic on the pod, and helps us sort out the complicated political and social functions (and the significant "traps") of imagining the past.
