The Three Languages of Politics

One of the simplest, most illuminating books I've ever read is Arnold Kling's The Three Languages of Politics.
Kling's idea: conservatives, liberals and libertarians
talk
about political issues in terms of three, separate axes:
liberals tend to view issues on the
oppressed
vs the
oppressor
axis
conservatives view issues on the
civilization
vs
barbarism
axis
libertarians view issues in terms of
freedom
vs
coercion
Kling wrote this book in 2013 (pre Trump), and last I heard was toying with a axes (cultured/elite vs ...not) to represent him and his followers, but I'm not positive where he's landed on that. I prefer the classic, three axes version myself.
