This volume comprises the complete proceedings, including an edited transcript of all discussion sessions, of the 1999 Ratio Conference 'Arguing with Derrida' at which Jacques Derrida responded to papers and took questions covering issues at the heart of contemporary thought in the English-speaking world. The text includes a series of important new contributions by Derrida on the relation of his work to analytical philosophy, the logic of argument, truth, ineffability, meaning, animal life, and the appeal to the ordinary in the work of Wittgenstein and J.L. Austin. Containing major new papers from Geoffrey Bennington and A.W. Moore, a panel discussion in which Tom Baldwin and Stephen Mulhall put detailed questions to Derrida, and the addition of an introduction by Simon Glendinning and afterword by Darren Sheppard, this volume will be essential reading for anyone interested in Derrida's work and its relation to contemporary philosophy in the English language.
