‘Man is by nature a political animal,’ Aristotle wrote. So what in nature makes humans political? How did nature make us that way? What does it mean to be political? When did being political begin and how did it develop? How do the natural sciences help us understand politics? What does science have to do with politics? In addition to American Politics, International Politics, Comparative Politics, and Philosophical Politics, what is Big Politics? These are the questions Lowell Gustafson thinks about in this piece.
