Perhaps no one but a genetic psychologist can realize how very widely the successive stages of life in man differ from each other. Underneath the tenuous memory continuum that is the chief basis of all feeling of identity between our present and former selves, deeper even than every unity of life plan and persistence of disposition, are the great changes the years bring. These are, indeed, so great that although they very commonly modulate, each into the next stage of the series by almost imperceptible gradations, we all really live not one but a succession of lives. Further than this, just as in dementia præcox the normal development of the psyche is permanently arrested in a juvenile stage, so, but far more commonly, the normal progress from maturity to senectitude is arrested; and in the decades of involution, which is just as progressive and interesting as evolution, the old cling to or leave with great reluctance their mature stage and so never achieve true senectitude. Just as the precocious dement balks in adolescence at the growing complexity and arduousness of the problems of adulthood and so fails to mature because he lacks the energy or hereditary momentum to do so, so the old very often find themselves inadequate to the new tasks involved in beating the great retreat. They cannot break from the things that are behind and reach forward to those that are before and they cling with a tenacity that is purely arrestive to a stage of life that has passed. They refuse to accept old age and to make the most and best of it, to face its tasks and to improve all its opportunities. If they do not paint, dye, pad, or affect the fashions and manners of the young (for old age may show traits of narcissism), when the call comes to move on to a new phase of life, their mentality defaults. This type of mental defect has never so far been adequately characterized
