Newer models of metapsychological abnormality should allow 1, more adequate classification of the normal and abnormal aspects of personality at any age and 2, more adequate classification of patients, for discussion with colleagues in other sciences. Scott feels a new method of classification using the

constitutional, zonal, ego, superego, and environmental aspects would permit more than a list of single-word diagnoses, although less than the usual metapsychological analyses. He concludes with some suggestions and a warning about future work along these lines.
