Lovers' Infiniteness
Courtly love economics
Donne treats love like a legal contract. 'Treasure,' 'purchase,' 'spent,' 'due,' 'bargain'—he's doing accounting, not romance.
Property law problem
Legal principle: if you own the land, you own what grows on it. He's claiming future love as real estate.
The paradox pivot
Sudden reversal—after two stanzas demanding everything, he now says he doesn't want it. Watch what this enables.
Gift theory paradox
If you can give your heart away repeatedly, you never truly gave it the first time. Donne's playing with what 'giving' means.
The metaphysical solution
Instead of trading hearts (which creates the paradox), merge them. Unity solves the ownership problem.
