His evidence, if he were called by law
To swear to some enormity he saw,
For want of prominence and just belief,
Would hang an honest man and save a thief.
Through constant dread of giving truth offence,
He ties up all his hearers in suspense;
Knows what he knows as if he knew it not;
What he remembers, seems to have forgot;
His sole opinion, whatsoe’er befall,
Centring at last in having none at all.
