The author examines the function of the analyst who may distort the unconscious communication with the patient by means of the expression of his countertransference. He studies a disturbance in curiosity and in symbolisation in a patient with a narcissistic pathology. Both problems were related to this failure in interpreting. The curiosity of the patient, which initially seemed to be non-existent, was found to be directed towards investigating the mind of the analyst, this being his sole purpose. The disturbance in symbolisation was manifested as a constant verbal acting out, which was expressed as verbal communication empty of meaning. A change in the interpretative attitude enabled a modification in the objective of the curiosity, which became focused on investigating his own inner world, and the emptiness of the verbal communication was replaced by representations. This change in communication allowed the analyst to relate the facts of the psychoanalytic relationship both with the patient's phantasy and with the events in his history. An idealised identification with destructive aspects of the mother towards the father was discovered. This idealisation had been sustained by the analyst by means of his errors in interpreting. The author explores disturbances in symbol formation and in the use of symbols, and he considers the different states of emptiness.
