If not simple opposition or simple juxtaposition, what is the relation between the writings to which Derrida and Levinas appose their signatures? What would each endorse in the writings of the other? What is it to sign and endorse? How does one assume responsibility, and how does one avoid assuming it? These are some of the probing questions that the prominent Continental philosopher John Llewelyn takes up in "Appositions", which brings together and synthesises fifteen essays written during the past twenty years. Drawing out the metaphor of the Greek letter chi, or 'x', Llewelyn apposes the discussions of the two philosophers, applying their thought to one another.In considering the work of Derrida and Levinas from the points of view of philosophy, linguistics, logic, and theology, Llewelyn invokes a diverse array of philosophers, theologians, and literary figures, including Austin, Defoe, Hegel, Heidegger, Jankelevitch, Kant, Mallarme, Plato, Ponge, Ramsey, Rosenzweig, Russell, Saussure, and Valery.This book by a powerfully original thinker and first-rate interpreter is essential reading for all those interested in the writings of Derrida and Levinas and in the ways in which their thinking intersects. John Llewelyn has been Reader in Philosophy at the University of Edinburgh, Visiting Professor of Philosophy at the University of Memphis, and the Arthur J. Schmitt Distinguished Visiting Professor of Philosophy at Loyola University, Chicago, Illinois. Among his publications are "Beyond Metaphysics"; "The Hermeneutic Circle in Contemporary Continental Philosophy"; "Derrida on the Threshold of Sense"; "The Middle Voice of Ecological Conscience"; "Emmanuel Levinas: The Genealogy of Ethics"; and "The HypoCritical Imagination: Between Kant and Levinas".
