Modesty and unselfishness – these are virtues which men praise – and pass by. – André Maurois, Ariel, 1924

The greatest virtues are those which are most useful to other persons. – Aristotle

Seek virtue rather than riches. You may be sure to acquire the first; but cannot promise for the latter. No one can rob you of the first without your consent; you may be deprived of the latter a hundred ways. – James Burgh, The Dignity of Human Nature: Book III. Of Virtue, 1754
