"nothing seems finer and more glorious than to retaliate on an enemy,
so far as it can be done without the country's ruin. But if this is

Cornelia knew her son; his creed was just the reverse.
Vengeance he

he himself and even the commonwealth were to be ruined by it--the
presentiment, that fate would overtake him as certainly as his brother,
drove him only to make haste like a man mortally wounded who throws
himself on the foe.
The mother thought more nobly; but the son--
with his deeply provoked, passionately excited, thoroughly Italian
nature--has been more lamented than blamed by posterity, and posterity
has been right in its judgment.
