Metaphysics: a literary application

Verses 4 & 5 of John Donne's
"A Valediction Forbidding Mourning" (1611)

Dull sublunary lovers' love
(Whose soul is sense) cannot admit
Absence, because it doth remove
Those things which elemented it.

But we, by a love so much refined
That ourselves know not what it is,
Inter-assured of the mind
Care less eyes, lips, and hands to miss.
