In their excellent book, Eva Erman and Niklas Möller shed new light on the classic question of the relation between political theory and practice. By way of a masterful analysis of current methodological approaches, they show how one avoids one-sided "ideal-based" as well as "realistic" theoretical perspectives. Essentially, they present a powerful and much-needed argument against reductionist notions of political normativity.
