In this connection one may reflect, with Louise Creighton, that as older people caused the late war, while the younger fought it, when the latter came home the places that had to be found for them involved a great deal of displacement, so that the tension between old and young has been greatly increased since the close of the war. We also recall the view of George R. Sims,[8] that the effect of the war upon the old was depressing because they felt they must die when the world was in darkness and without realizing the prayer of Simeon. The young anticipated the harvests of peace, but for the old the prospect of dying before this harvest was garnered was often pathetic. Charles W. St. John[9] résumés the experimental studies of Ranschenburg and Balint which show that all activities of judgment, association, etc., are retarded, errors increased, and ideas impoverished in old age. De Fursac tabs the traits of normal senile dementia as (1) impaired attention and association; (2) inaccurate perception of the external world, with illusions and disorientation; (3) disordered memory, retrograde amnesia, and perhaps pseudo-reminiscence; (4) impoverishment of ideas; (5) loss of judgment; (6) loss of affectivity, along with morbid irritability; and (7) automatism. There may be ideas of persecution or delusions of greatness. Youthful items of experience hitherto only in the fringe of consciousness now press to the center, and youthful contents are revived. There is a tendency to depart from inductive procedure toward a priori methods, where feelings and beliefs are criteria, and especially, as Fechner showed, to introversion. There is less control and regression first shows itself in the intellect, which is last to develop.
