The production of a book such as this is a collaborative effort. Good committee members take turns to shoulder responsibilities; the greater share of the organisation of the lectures themselves was undertaken by Deana Rankin. This is the first of the Oxford Amnesty books in which there has been a division of labor between editor and introducer. I am grateful to Jonathan Rée for responding to the challenge of introducing so diverse a set of lectures and for doing so with such good grace. To the lecturers themselves, particular thanks are due. All contributors to the Oxford Amnesty Lectures give of their time and expertise freely. Contributors to this volume have been more than generous in response to the demands I have made on their patience and their goodwill during the preparation of the lectures for publication. It has been a privilege to work with the texts of people who write with such wit, passion, and integrity; I am most grateful to them.
