Society expects man to be a passive social animal who believes like the People of the Field in "Jurgen" that "to do what you always have done" and "what is expected of you" are the twin rules of life. This, of course, is not true. The wanton crucifixion of impulses, the unnecessary blocking and frustration of the drives and urges, are an evil that reflects itself in sophistication, ennui and boredom, dissatisfaction, melancholy, fatigue, anxiety and neurosis.
The failure of the mind in old age is often less the results of natural decay, than of disuse. Ambition has ceased to operate; contentment bring indolence, and indolence decay of mental power, ennui, and sometimes death. Men have been known to die, literally speaking, of disease induced by intellectual vacancy.
