Using a few well-chosen clinical examples, the author describes people who have a leading character trait of nagging, which he believes to be based on a feeling of weakness. Nagging is the projection of a high ideal that has not been met and it leads for a time to a feeling of some power. The person who is nagged, the 'naggee', is often patient, tolerant, quietly capable, with great self-control and concern for others. The guilt of the 'naggee' is easily aroused and he accepts it. This reviewer adds that the usefulness of the article may well be that a therapist who reads it may become aware that among the pitfalls of therapy are the roles of nagger or 'naggee' that the therapist assumes without awareness, and particularly that he is inviting the patient to play the contrapuntal role, especially in termination.
