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.
