I’m an eliminativist about phenomenal consciousness. :) So I’m pretty far from the dualist perspective, as these things go...!
But discovering that there are no souls doesn’t cause me to stop caring about human welfare. In the same way, discovering that there is no phenomenal consciousness doesn’t cause me to stop caring about human welfare.
Nor does it cause me to decide that ‘human welfare’ is purely a matter of ‘whether the human is smiling, whether they say they’re happy, etc.‘. If someone trapped a suffering human brain inside a robot or flesh suit that perpetually smiles, and I learned of this fact, I wouldn’t go ‘Oh, well the part I care about is the external behavior, not the brain state’. I’d go ‘holy shit no’ and try to find a way to alleviate the brain’s suffering and give it a better way to communicate.
Smiling, saying you’re happy, etc. matter to me almost entirely because I believe they correlate with particular brain states (e.g., the closest neural correlate for the folk concept of ‘happiness’). I don’t need a full reduction of ‘happiness’ in order to know that it has something to do with the state of brains. Ditto ‘sentience’, to the extent there’s a nearest-recoverable-concept corresponding to the folk notion.
