This is an expanded edition of the first book to argue for the ethical turn in Derrida's work. Simon Critchley's first book, The Ethics of Deconstruction, was originally published to great acclaim in 1992. It was the first book to argue for the ethical turn in Derrida's work and to show as powerfully as possible how deconstruction has persuasive ethical consequences that are vital to our thinking through of questions of politics and democracy. This new edition contains three new appendices and a new preface where Critchley reflects upon the origins, motivation and reception of The Ethics of Deconstruction.
