The author presents Herbert Rosenfeld’s methodology as evidenced in Impasse and Interpretation, by linking it with certain notions of Klein and Bion. She considers that Rosenfeld’s methodological concerns constitute the dominant aspect of his later work, marked by the consideration of trauma. The model of psychotic transference is not reduced either to schizophrenia or to negative confusional and narcissistic states, but is extended to borderline states and to any analytical process. With this approach, the author emphasizes the importance of reflecting on the interpretation of transference and countertransference, backed by the different modalities of projective identification and the notion of container-contained. Taking into account the impact of the analyst’s state of mind on the patient, as well as dealing with emotional aspects between them, is a concern at the heart of contemporary analysis.
