"And Coxcombs vanquish Berkeley by a Grin"

This line is taken from Dr. Brown's *Essay on Satire*, part ii. v. 224. The entire couplet is— "Truth's sacred fort th' exploded laugh shall win, And coxcombs vanquish Berkeley by a grin." Dr. Brown's Essay is prefixed to Pope's "Essay on Man" in Warburton's edition of Pope's *Works*. (See vol. iii. p. 15., edit. 1770, 8vo.)
