Fortunately, the challenge of alienation is now again taken seriously in intellectual discussions. Already years ago, Axel Honneth made the reflection on alienation a defining issue for social philosophy per se, and as the prime example of social philosophy, he brought forth Critical Theory. Within this horizon, recently two conceptions of alienation have been proposedby Rahel Jeaggi and Hartmut Rosa, and the present article takes issue with both of these proposals, criticizing in particular their anti-essentialism. Hence, questioning the post-metaphysical agenda (...) that Jaeggi has inherited from Honneth, I criticize her juxtaposition of the existentialist and the Marxist critique of alienation, her understanding of the good life as autonomy, and finally her acceptance of post-modern and liberal criticism of metaphysics and ontology. Turning to Rosa, I appreciate his societal approach to the critique of alienation, emphasizing the significance of capitalist modernity, but also he accepts the post-metaphysical agenda, and his aesthetic idea of the good life as resonance remains strongly individualistic. Both of these conceptions of alienation thus have ideological implications that threatens to turn upside down the original intentions and implications of Critical Theory in relation to social and political justice. To conclude, the criticism of capitalism, political economy and real life politics is still relevant for understanding alienation, and therefore it is worth returning to the classics of the discussion.
