Twenty-five years after the publication of Derrida's Politics of Friendship (Politiques de l'amitie, 1994), this edited collection gathers twenty-three critical chapters each revisiting this underappreciated text, including Derrida's Geschlecht IV, an essay excluded from the English translation.Engaging closely with Derrida's text are analyses, extensions and critiques of the work. It not only reconsiders the place this book occupies in Derrida's political philosophy but also its potential for contemporary politics, when the promises and perils of political friendship have reappeared, intertwined with both nationalist and anti-nationalist political programmes.
