Book excerpt: This book explores the thought of Jacques Derrida as it relates to the tradition of apophatic thought--negative theology and philosophy--in both Western and Eastern traditions. Following the Introduction by Toby Foshay, two of Derrida's essays on negative theology, Of an Apocalyptic Tone Newly Adopted in Philosophy and How to Avoid Speaking: Denials, are reprinted here. These are followed by essays from a Western perspective by Mark C. Taylor and Michel Despland, and essays from an Eastern perspective by David Loy, a Buddhist, and Harold Coward, a Hindu. In the Conclusion, Jacques Derrida responds to these discussions.
