Contemporary philosophical pluralism recognizes the inevitability & legitimacy of multiple ethical perspectives & values making it difficult to isolate the higher-order principles on which to base a theory of justice. Rising up to meet this challenge Rainer Forst a leading member of the Frankfurt Schools newest generation of philosophers conceives of an autonomous" construction of justice founded on what he calls the basic moral right to justification. Forst begins by identifying this right from the perspective of moral philosophy. Then through an innovative detailed critical analysis he ties together the central components of social & political justice--freedom democracy equality & toleration--and joins them to the right to justification. The resulting theory treats "justificatory power" as the central question of justice & by adopting this approach Forst argues we can discursively work out or "construct " principles of justice especially with respect to transnational justice & human rights issues. As he builds his theory Forst engages with the work of Anglo-American philosophers such as John Rawls Ronald Dworkin & Amartya Sen & critical theorists such as Jurgen Habermas Nancy Fraser & Axel Honneth. Straddling multiple subjects from politics & law to social protest & philosophical conceptions of practical reason Forst brilliantly gathers contesting claims around a single elastic theory of justice."
