A growing genre of ‘crisis studies’ traces liberal-democratic instability to technocratic reformism and populist reaction to it. Most contributions recommend restoring economic growth, rebuilding civic culture and eschewing populist ‘us-versus-them’ narratives. This literature relies on a problematic way of thinking we label irenicism, and show to be a contemporary variant of what political realists call progressive moralizing. Irenicism portrays liberal-democracy as the product of voluntary consensus among rational individuals to sustain institutions that, by promoting endless economic growth, support universal interests (...) and values. By way of a synthesis of realist thinking and Dewey’s pragmatic approach to experimental theory-building, irenicism is shown to preserve a lacuna for political interpretation. The task for current political theory should not be to affirm old ideas in the face of new challenges. Rather, it should be to do away with ‘traditionalized’ ideas, to clear the field for experimental responses to democratic political thought and action. (shrink)
