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.
