It looks like most political commentators are just talking past one another. Why?
Arnold Kling hazards a guess, arguing that people don’t understand one another because they have fundamentally different visions of how the world works. According to Kling, conservatives see the world as a conflict between civilization and barbarism, liberals see it as a conflict between oppressors and the oppressed, and libertarians see it as a conflict between liberty and power.
Kling is clear that he is offering a hypothesis rather than an exhaustive empirical study. It is a short and easy read, and it is one that (I expect) will help us make sense of political history and the political present.
