Negative reactions of patients to therapists may be due as much to the therapist's personality as to the transference. A useful therapist is one emotionally sensitive to a wide variety of signals from the patient and yet objective about what he perceives. Anxiety in the therapist keeps him from awareness of facts or psychic phenomena in his patients, but serves as a valuable indication of stagnation or harmful processes in therapy. A therapist may be threatened by disillusionment in his own powers of healing, or may try magically to help himself through his work with others. He may need to keep the patient sick so as to dominate him, or he may feel threatened by the patient's infantile sexuality or by his frankness in pointing up the therapist's weaknesses—especially in the case of schizophrenics. The author quotes Kaufman, 'The qualification for a psychoanalyst is that he should have had a neurosis', and concludes that a successful therapist expresses benevolence rather than his defenses in treatment.
