Clifton and David are honored to have Stephan Kinsella on the show to discuss argumentation ethics and talk about his concept, "estoppel." We will get Stephan's full take on argumentation ethics and how it relates to libertarian arguments and principles such as the NAP. Stephan is also the author of the libertarian book, "Against Intellectual Property." Stephan is a fellow at the Mises Institute and a practicing attorney. Join the Punching Left! team for what we believe should be a very educational show!
