Laplace demon cannot assess sentience” is begging the question just as much as “philosophical zombies are possible” It’s obviously true only if you assume the premise of counsciousness epiphenomenality.
It’s also true if you assume there is no possible reductive explanation of phenomenal consciousness … which dualists like Arturo do.
If Laplace’s Demon knows All Physics, and the
reductive explanation of phenomenal consciousness isn’t part of All Physics, then Laplace’s Demon doesnt know any facts about consciousness.
We belive this, because Laplace demon has an explanation of all material facts (that is physicalism, isn’t it?). What else can you “know”, what else can you explain?
The most you can do is to trust is the “neural correlates of conscience” research agenda, but it depends on having a Rosetta stone (=credible accounts of subjective experience), and beyond other humans, we have nothing (while perhaps IA translation of some cetacea will be available, increasing a little bit the “interpretability circle”).
But we will never know “What Is It Like to Be a Bat?”
