"No matter how full a reservoir of maxims one may possess, and no matter how good one's sentiments may be, if one has not taken advantage of every concrete opportunity to act, one's character may retain entirely unaffected for the better. With mere good intentions, Hell is proverbially paved. [The purpose of knowledge is to perceive plans which can be focused into action and through action the creation of character and self-respect.]"
