The virtue that fights on behalf of fairness

Cicero, On Duties, Book I, p.26

The Stoics define courage will when they call it the virtue which fights on behalf of fairness...a spirit which is ready to face danger, but is driven by selfish desire rather than common benefit should be called not courage, but audacity...it is a hateful fact that loftiness and greatness of spirit all too easily give birth to willfulness and excessive desire for pre-eminence...the loftier a man's spirit, the more easily he is driven by desire for glory to injustice. This is slippery ground indeed: scarcely a man can be found who, when he has undertaken toil and confronted dangers, does not yearn for glory as a kind of payment for his achievements.
