Drawing on Arnold Schönberg’s seminal opera “Moses and Aron”, the comment focuses on the role of holistic politics in Andrew Arato’s and Jean L. Cohen’s “Populism and Civil Society”. It argues that their anti-populist stance is too quick in dismissing a politics which is driven by representing and re-constituting the whole of the social order. Against this backdrop, a rejuvenation of the political left may not consist in a rejection of holism as such but in a popular politics which relies on functional equivalences.
