I would like to thank the editors, Dr Michael Feldman and Mrs Elizabeth Bott Spillius who have organized these papers, and, with great patience and understanding, attempt to introduce them to the reader.

Among many other colleagues I particularly wish to thank Dr Hanna Segal, who has over years mulled over, discussed, and always constructively criticized the majority of the papers in this volume.

I also want to thank the following for their kind permission to reproduce copyright material: The International Journal of Psycho-Analysis (Chapters 1, 2, 3, 7, 9, 10, 11), Jason Aronson Inc. (5), Caesura Press (6), the Bulletin of the European Psychoanalytical Federation (8), International Universities Press (12), Psychoanalytic Psychotherapy (13), and The Psychoanalytic Quarterly (15).
