Abstract
In a modern, plural society, there can be no settled agreement on the concrete legal content of a country's constitution. The idea of the constitution is nonetheless pivotal in contemporary, liberal‐minded theories of political justification, such as the ones advanced by Jürgen Habermas and John Rawls. Justification in these theories depends finally on “constitutional patriotism,” a consciously shared sentiment arising from an ethical assessment of their country by the country's people, according to which the country credibly pursues a certain regulative political ideal for which the constitution stands.
