"Given currency by Jrgen Habermas in the late l980s, 'constitutional patriotism' has emerged as an appealing principle for post-national political allegiance. Jan-Werner Mller traces the long postwar history of the concept, takes honest account of the conservative critiques it has provoked, but proposes that it can serve as a robust norm for European Union citizenship. This is a profound meditation with real importance for contemporary political society."
