Liberal Constitutionalism in the 21st Century

Populists openly and proudly challenge liberalism. Less obvious is whether and how contemporary liberals, especially of the Rawls/Habermas variety, should answer those challenges. Should they reassert the centrality of pluralism as part of the circumstances of justice? Or should “the fact of pluralism” be revisited under the pressure of contemporary political developments? Should liberals rethink the role of higher – constitutional – law in theorizing democratic legitimacy? Is our political age still post-metaphysical?
