Who, for the poor renown of being smart,
Would leave a sting within a brother's heart?
Parts may be prais'd, good-nature is ador'd;
Then draw your wit as seldom as your sword;
And never on the weak; or you'll appear
As there no hero, no great genius here.
As in smooth oil the razor best is whet,
So wit is by politeness sharpest set:
Their want of edge from their offence is seen;
Both pain us least when exquisitely keen.
