Reddit reviews Four systems

You would probably really enjoy the book Four Systems, which I'm sad to see is out of print. It was a textbook in my Intro to Poli Sci class. It presents four different systems of government -- social democracy, individual democracy, communism and fascism -- each from the perspective of someone who advocates the system. As a freshman I came out of each section (plus the introduction, which covers anarchism) feeling like "Wow, yeah, this actually makes a lot of sense!"
