QUOTE : <i>Vanity and ambition as education.</i> - So long as a man has not yet become an instrument of general human utility let him be plagued by ambition; if that goal has been attained, however, if he is working with the necessity of a machine for the good of all, then let him be visited by vanity; it will humanize him and make him more sociable, endurable and indulgent in small things, now that ambition (to render him useful) has finished roughhewing him.
