Frank Kirkpatrick is a theologian and former religion professor at Trinity College, where he taught for 47 years. He was also Colin’s advisor, overseeing his thesis on Soren Kierkergaard. Frank’s class on major religious writers made Colin want to be a double major in religion and history as an undergraduate. Now, more than 20 years later, they talk about some major figures in American and European philosophy and how the United States is becoming a more secular country. It’s an episode that takes on everything from Paul Tillich to Reinhold Niebuhr.
