The Enigma of Justice: Freedom and Morality in the Work of Immanuel Kant, G.W.F Hegel, Agnes Heller, and Axel Honneth offers a novel perspective on the idea of justice. Claire Nyblom argues that justice is a cultural and historical constant, routinely summoned as if it were a foundational concept to legitimate or challenge social arrangements. Instead, justice is characterized by a plurality of theories, containing regulative and critical dimensions that are in tension. Nyblom argues that the categorical imperative can be positioned as a strong evaluative standard that mediates plurality, creating a revisable idea of justice resistant to relativism. After identifying the originating architecture of Immanuel Kant and G.W.F Hegel, the discussion engages with the work of Agnes Heller and Axel Honneth, using the "pivots of justice" as an analytic lens focused on commonalities rather than differences. This framework leads to a dialogue between Heller and Honneth that strengthens their respective positions. The Enigma of Justice provides a valuable study and insight into the contemporary nature of justice. The book provides a useful orientation for students and scholars interested in debates about justice, and to those working in the areas of European philosophy, social and political theory, sociology, and the law.
