The Verge of Philosophy is both an exploration of the limits of philosophy and a memorial for John Sallis's longtime friend and interlocutor Jacques Derrida. The centerpiece of the book is an extended examination of three sites in Derrida's thought: his interpretation of Heidegger regarding the privileging of the question; his account of the Platonic figure of the good; and his interpretation of Plato's discourse on the crucial notion of the chora, the originating space of the universe. Sallis's reflections are given added weight-even poignancy-by his discussion of his many public and private philosophical conversations with Derrida over the decades of their friendship. This volume thus simultaneously serves to mourn and remember a friend and to push forward the deeply searching discussions that lie at the very heart of that friendship. "All of John Sallis's work is essential, but [this book] in particular is remarkable. . . . Sallis shows better than anyone I have ever read what it means to practice philosophy on the verge."-Walter Brogan, Villanova University.
