True Wit is Nature to advantage dressed
What oft was thought, but ne’er so well expressed;
Something whose truth convinced at sight we find,
That gives us back the image of our mind.
As shades more sweetly recommend the light,
So modest plainness sets off sprightly wit.
— Alexander Pope (1688–1744) English poet
