The ‘discipline’ of political ‘science’ (or in an earlier age ‘the law’) examines the way different institutional arrangements affect—as Harold Lasswell put it—who gets what, when, how. There is a large and fascinating library of books examining that question.
But the political struggle (the agon) is also the commons. How do ‘we’ disagree with one another? About what? Who is allowed to participate in the agon of politics? Not abstractly, as a matter of theory (the politics of the commons). But as a mater of strategic positioning and tactics. This may be the intersection of history, and political theory, and political practice.
