This article argues that Jacques Derrida’s Politics of Friendship presents an implicit but significant critique of Maurice Blanchot’s The Unavowable Community. In Blanchot’s text, the Other disrupts any sense of fusional or essentialist community. But Derrida criticises Blanchot for neglecting the need to negotiate my responsibility to infinite others. Derrida proposes a logic of the plus un, playing on this double meaning in French, where a need to count singularities (‘plus one’) disrupts the unity of community (‘no longer one’). For (...) Derrida, this offers a greater emphasis on those outside the boundaries of constituted communities, something he finds lacking in Blanchot. I demonstrate that Derrida’s position is a challenge to an emerging xenophobic discourse in 1980s French politics. I propose, therefore, that Derrida’s difference with Blanchot is motivated as much by a political difference as a philosophical one, with Derrida judging Blanchot’s account inadequate for contemporary political concerns.
