“For friendship is a virtue, or involves virtue; and also it is one of the most indispensable requirements of life. For no one would choose to live without friends, but possessing all other good things. In fact rich men, rulers and potentates are thought especially to require friends, since what would be the good of their prosperity without an outlet for beneficence, which is displayed in its fullest and most praiseworthy form towards friends? and how could such prosperity be safeguarded and preserved without friends? for the greater it is, the greater its insecurity. And in poverty or any other misfortune men think friends are their only resource. Friends are an aid to the young, to guard them from error; to the elderly, to tend them, and to supplement their failing powers of actions; to those in the prime of life, to assist them in noble deeds.” Aristotle, Nicomachean Ethics VIII. i.1.
