This year marks not only the 75^th anniversary of The Psychoanalytic Quarterly, but also the 80^th anniversary of the Revue Française de Psychanalyse. In joint tribute and by agreement between the Editors, each journal is publishing an article representative of the other's psychoanalytic tradition. In July 2007, the Revue published Loewald's “Internalization, Separation, Mourning, and the Superego,” introduced and translated for the first time into French by Richard B. Simpson, and in this issue of the Quarterly we are publishing Michel de M'Uzan's “The Same and the Identical,” introduced by Dominique Scarfone and translated for the first time into English by Richard B. Simpson (with the assistance of Monique Panaccio). I am very grateful to Simpson, Scarfone, and to the Editor of the Revue Française de Psychanalyse, Denys Ribas, for making this joint celebration possible.
