This article deals with the political challenges that European liberal democracies confront in relation to their internal national pluralism. After analysing two analytical distortions of Western political thought –the fallacy of abstraction and the usual shortcomings of this tradition in relation to pluralism- the article presents twelve elements for a political and moral refinement of plurinational liberal democracies. These elements are linked with an analytical and normative collective dimension usually marginalized and which cannot be reduced to the individualist, universalist and stateist approach of traditional democratic liberalism and constitutionalism. Finally, the article deals with the practical solutions offered by comparative politics to try to accommodate nationally pluralist societies according to reviewed liberal-democratic patterns.
