The author discusses some of the characteristics of Roy Schafer's contributions to psychoanalysis that he finds most valuable, such as his openness to uncertainty, his anti-reductive view of analytic constructions, his unique formulation of the analyst's role, and his close attention to how the patient engenders particular emotional reactions in the analyst. The author also presents a clinical vignette illustrating the value of the analyst's tolerance of uncertainty in the face of the patient's push for interpretations, explanations, and reassurance.
