Abstract
The essay ends addressing the fracture lines dividing the European Left as far as the integration process is concerned, also among those who disapprove of the levelling of social democracy with its dominant austerity policies imposed by communitarian institutions. A “duel on the Left” – we one would have written – all the more interesting because Martinelli compares two German intellectuals, both hostile to the lasting compromise of the Große Koalition that governs the country and on which the destiny of the European Union depends. Wolfgang Streeck, director of the Max-Planck-Institut für Gesellschaftsforschung in Cologne, and Jürgen Habermas, the grand maestro of critical theory.
