A Fever
Misogyny as threat
Emotional blackmail disguised as compliment—if you die, I'll hate all women because none will match you. Classic Donne move: love argument built on spite.
World's soul
**Anima mundi**—the Neoplatonic concept that a soul animates the cosmos. He's claiming her breath literally keeps the universe alive.
Apocalypse debate
Medieval scholars argued whether the world would end by fire or flood. He's saying philosophers missed the obvious: her fever could be the apocalyptic fire.
Meteors vs. firmament
Aristotelian cosmology: meteors are temporary atmospheric phenomena, but the firmament (celestial sphere) is eternal and unchanging. Her beauty is the latter.
Final turn
After 24 lines of cosmic hyperbole, he admits the fever is just his own obsession—it's in his mind, not the universe. Then doubles down anyway.
