Straddling the divide between universalism and relativism, agonistic reason as construed by Foucault and Castoriadis dismisses universal foundations without becoming context-bound or inescapably subjectivist. It is propelled by a strong commitment to freedom and it draws flexibly on available resources and its creative potentials in order to vindicate its conditional claims. This provides a hyper-critical and liberating mode of critical reason which delves into the underlying norms of agency in order to open them up to question and to enhance free (...) self-direction. The argument that is put forward, then, is threefold. Firstly, Castoriadis’ accent on ontological reflection, the imaginative disclosure of new figures and the global intent of critique contrasts with Foucault’s account of agonistic reason and yields a more robust version of critical rationality. Secondly, this form of reflective agonism can effectively address fundamental challenges and reason across contexts, tackling moral and other issues that arise from cultural innovation and exchange. Lastly, agonistic reason need not, and should not, call upon absolute principles on any level in order to uphold its own values and do justice to its radical others. (shrink)
