His research brings together social and political philosophy and theory with the comparative-historical sociology of modern societies in Europe, Latin America and southern Africa. He has done comparative research in the history of the social sciences and has contributed to debates about the so-called Axial Age, while his recent work has addressed questions of historical progress and social and political transformations. He is a former Professor of Social and Political Theory at the European University Institute, Florence, and a former Professor of Sociology at the University of Warwick.
