Sonnet 46

Mine eye and heart are at a mortal war
How to divide the conquest of thy sight;
Mine eye my heart thy picture's sight would bar,
My heart mine eye the freedom of that right.
My heart doth plead that thou in him dost lie--
A closet never pierced with crystal eyes--
But the defendant doth that plea deny
And says in him thy fair appearance lies.
To 'cide this title is impanneled
A quest of thoughts, all tenants to the heart,
And by their verdict is determined
The clear eye's moiety and the dear heart's part:
As thus; mine eye's due is thy outward part,
And my heart's right thy inward love of heart.

-William Shakespeare
