In this article, I consider the role of institutions in Jacques Derrida’s political engagement. In spite of Derrida’s significant involvement with political causes throughout his life, his engagements have received little sustained attention, and this is particularly true of his work with institutions. I turn to two such cases, the Collège international de philosophie and the Parlement international des écrivains and argue that these represent an alternative mode of institutionalisation. These institutions seek to destabilise other institutions as well as themselves.Looking (...) closely at the institutions that Derrida founded, we see three common characteristics emerge. These institutions are anti-hegemonic,self-reflexive and international. I then connect these to Derrida’s thought, offering a reading of the undecidable, which brings forth the importance of conventions in the decision. Finally, I demonstrate that the three shared characteristics of Derrida’s institutions form part of an effort to open up space for the possibility of alterity. Through this, and beyond a distinction between theory/practice, we come to see Derrida’s institutional engagements as an active form of critique, both of other institutions and themselves. (shrink)
