The paper aims to clarify the interpretation of Kantian morality and Hegelian ethical life given by Honneth and Habermas; it try in particularly to explain the several meanings and forms of Honneth’s relaunch of Hegel’s conception of Sittlichkeit. The Author aims at the same time to show some structural limits of this neo-Hegelian ethical perspective from a political point of view, also in relation to the concept of «immanent critique» adopted by Honneth, and differentiated by him from the concept of «internal criticism» developed by Michael Walzer. The Author observes that the immanent approach of Honneth’s normative reconstruction and social critique seems to have some problems to take in account the plurality of different and conflicting ethical-political orientations.
