The author describes Harry Guntrip (1901-1975), who was well known for his expositions of psychoanalytic theory. His personal symptoms had led him to seek psychoanalytic help. Before his death he wrote an account of his analysis with Fairbairn and his psychotherapeutic sessions with Winnicott. Both of them had helped him but not cured his basic problems. The author argues from Guntrip's own accounts that he reached a deep unconscious resistance to the process of analysis, as Fairbairn believed, and that Winnicott came near to interpreting the source of this resistance. Freud's paper of 1917 on anal erotism is used to suggest an approach by which it might have been interpreted and analysed.
