The obsessive patient fights doubt by the reaction-formation of heightened angry words of certainty. These, however, bring a turn of new doubt, which requires additional certainty. When the doubt threatens to invade the reaction-formation, the latter is replaced by the mechanism of undoing the angry, dogmatic speech by way of a quieter, more amenable attitude. At this point arises the best opportunity for acceptance of interpretation by the patient. The decreased auditory impact from his own words, which have magical power for him, enables him to listen to himself and his analyst and thus connect the internal parts of himself previously dissociated. It is important that the communication of the analyst not be impersonal.
