Influenced by Melanie Klein as well as by Freud, Strachey sees the essence of psychoanalytic therapy as being the alteration of the patient's superego through a series of 'mutative interpretations'. The mutative interpretation is always a transference interpretation and occurs in two stages. First, the patient is made aware of the quantity of id energy directed at the analyst; secondly, the patient becomes aware that this energy is directed toward a transference object rather than a real one. Through constant dosing of such interpretations, there occurs an amelioration of primitive superego and id elements, and the psychic organization is freed to grow toward greater maturity.
