O, what authority and show of truth

Can cunning sin cover itself withal!

William Shakespeare (1564-1616): Much Ado about Nothing. Act iv. Sc. 1.

And art made tongue-tied by authority.

William Shakespeare (1564-1616): Sonnet lxvi.

But man, proud man,

Drest in a little brief authority,

Most ignorant of what he's most assured,

His glassy essence, like an angry ape,

Plays such fantastic tricks before high heaven

As make the angels weep.

William Shakespeare (1564-1616): Measure for Measure. Act ii. Sc. 2.

Small have continual plodders ever won

Save base authority from others' books.

These earthly godfathers of heaven's lights

That give a name to every fixed star

Have no more profit of their shining nights

Than those that walk and wot not what they are.

William Shakespeare (1564-1616): Love's Labour's Lost. Act i. Sc. 1.
