The paper explores the concept of truth in Bion's theory and in the post-Bionian context of the analytic field. Truth is addressed on three levels: epistemological, metapsychological, and clinical. Bion criticizes positivism in psychoanalysis, and the same vertex when it appears in psychoanalysis itself, stating that the search for truth at all costs is similar to the arrogance and stupidity of the psychotic part of the personality. He revolutionizes the analytic concept of truth by orienting it to the function of the emotional linking between analyst and patient rather than to content. Post-Bionian analytic theory further develops these concepts. In a field or radically intersubjective perspective, the author emphasizes the shift from an “I/you” perspective to a “we” perspective. The treatment is less about the abstract search for supposed truths and more about the truth being expressed in the process of emotional and affective attunement.
