In all intellectual and scholastic studies, there is a secondary result which, whether recognized or not, is their most valuable one when judged from an evolutionary standpoint. It is the power of concentrated attention. Even if the student fails to master his subject or to solve his problem, nevertheless to the extent that he sincerely and diligently tries, this power is necessarily drawn upon, used, and developed. Both the mental effort needed to attend to the subject or problem and the desire to wrest the meaning of it, benefit the student even when his studies fail in their specific object. From the one he progresses a step forward toward greater ability to concentrate. From the other he gets a stimulus to his aspiration for truth. One day both will be applied to the spiritual quest.
