Fruitful discussion of what constitutes ego distortion requires more precise definitions than at present exist, as well as exact knowledge of the part or layer of the ego which is distorted, the how, when, and why, and relationships of the distortion. Complications arise from various other sources, among them the fact that even the 'normal' adult can manifest structural, economic, and dynamic dysfunctions. Glover suggests that the current totally unsatisfactory system of classifying mental disorders is a bar to urgently needed advances in diagnosis and prognosis. He offers a system of formulae under which much more precise designations of the nature of disorders can be indicated. He believes such precision in diagnostic formulation 'would immensely strengthen our capacity to assess the results of analytic treatment'.
