A Deceivable World
Illustration
by William Shakespeare

The world is still deceiv'd with ornament.
In law, what plea so tainted and corrupt
But, being season'd with a gracious voice,
Obscures the show of evil? In religion,
What damned error, but some sober brow
Will bless it and approve it with a text,
Hiding the grossness with fair ornament?
There is no vice so simple but assumes
Some mark of virtue in its outward parts.

The Merchant of Venice, Act III, by William Shakespeare
