"Let those find fault whose wit's so very small, They've need to show that they can think at all; Errors, like straws, upon the surface flow; He who would search for pearls, must dive below. Fops may have leave to level all they can; As pigmies would be glad to lop a man. Half-wits are fleas; so little and so light, We scarce could know they live, but that they bite."
