Lebovici's purpose is to discuss the theory of supervision in his institute and how that institute's suppression of the training analyst's report influences supervision. There were difficulties with this policy. Under the influence of Jacques Lacan and other dissenting members, a split occurred in 1953, and Lacan's duties as a teaching analyst were taken away from him by the International Psycho-Analytical Association. Lacan then formed the Freudian School at Paris. Lebovici points out that the supervisor must sometimes comment on the candidate's analysis. He hopes that the history of the development of his institute is helpful in understanding the development of dissenting groups. He also describes vividly how the supervisor can add life to the candidate's analysis of his patient.
