Rosenfeld's final work, Impasse and Interpretation (1987), focused on the possibility of the overcoming of critical moments of impasse with difficult patients. Rosenfeld was increasingly convinced that such potentially destructive impasses were predicated on the existence of blind spots in the analyst,[10] thus pointing the way for the later developments of intersubjective psychoanalysis.
