Conversation: Bion and Winnicott.

In 2023, THE A-SANTAMARIA PSICOANALISIS MEXICO ASSOCIATION planned the Online Conversations of W. Bion to generate dialogues with outstanding colleagues about the divergences and convergences of Bion with the work of André Green, Jean Laplanche, Ignacio Matte Blanco and D.W. Winnicott. The need to share thoughts about these authors' works and their links with others, facilitated widespread international dialogues about these authors and placed them all in a field of exchange, debate and challenge. The Online Conversations underlined the new dimensions in which Bion and Winnicott placed psychoanalytic theory and technique. Five outstanding presentations illustrate their understanding and grasping of these dimensions, each followed by an author exchange. These authors provide an in-depth inquiry into a wide range of topics: Angela Joyce looks at object constancy and absence through the lens of Winnicott's (1977) The Piggle; Dominque Scarfone examines the concept of contact barriers among Freud, Bion and Winnicott; Howard B. Levine discusses absence, failure and the negative in the work of Bion, Winnicott and Green; Lesley Caldwell links the works of Bion and Winnicott in addressing being alone and with others, and communicating and not communicating; finally, Rudi Vermote shows how Bion's and Winnicott's views on regression and formlessness complement each other.
