In this accessible contribution to the burgeoning literature on democracy’s travails and what to do about them, Jan-Werner Müller makes a case for hard borders and fundamental principles. These are not the hard borders desired by authoritarian leaders. Instead, Müller asks us to go back to basics (he uses the concept riduzione verso il principo) to establish some hard borders in our understanding – and hence practice – of democracy. Those borders should be drawn around the fundamental democratic principles of uncertainty and equality. At its most basic, this is a call to reimagine and reinvest in the intermediary institutions of representative democracy – particularly parties and autonomous media – to restore the infrastructure of democratic politics in the developed world.
