"Suit the action to the word, the word to the action, with this
special observance, that you o'erstep not the modesty of nature:
for any thing so o'erdone is from the purpose of playing, whose
end, both at the first and now, was and is, to hold as 'twere the
mirror up to nature: to show virtue her feature, scorn her own image,
and the very age and body of the time his form and pressure."
-Hamlet Act 3, Scene 2
