Arnold Kling, author of The Three Languages of Politics, talks with EconTalk host Russ Roberts about the ideas in the book. Kling argues that Progressives, Conservatives, and Libertarians each have their own language and way of looking at the world that often doesn't overlap. This makes it easier for each group to demonize the others. The result is ideological intolerance and incivility. By understanding the language and mindset of others, Kling suggests we can do a better job discussing our policy disagreements and understand why each group seems to feel both misunderstand and morally superior to the other two.
