The present volume contains works which respond to this obligation to give account of the psychoanalytic experience. The papers by overseas analysts: Eric Porge and Joel Dor from France, and Gustavo Etkin, who visited and worked intensively with us, and Ivan Corrêa from Brazil, are the product of an ongoing dialogue between The Freudian School of Melbourne and analysts from other Schools. Such dialogue situates itself precisely in that place where unity, as the mask of that which is impossible to sustain, absents itself.
