We talk a lot about current constitutional issues on this show. We also talk a lot about history. And sometimes, we pause, take a deep breath, and talk about Big Ideas - note the capital letters.That's what a group of scholars did recently at Montpelier's Center for the Constitution, and our host, Stewart Harris, was among them. He shares a conversation he had with another conference participant, Brad Rourke, about two big issues in constitutional theory: political participation and political ethics. We also hear from Doug Smith, the Executive Director of the Center for the Constitution, about why such conferences are important.It will blow your mind.
