“If physicalism is true, what exactly does it mean for neurons to be an experience rather than merely cause or correlate with one?”
Carl Sagan
You're asking the hard question, but physicalism doesn't claim neurons *are* experience—it claims experience *is* what certain neural processes *do*. The real puzzle: why does physical activity feel like something? That's the explanatory gap, not physicalism's failure.

“Fair. But if the explanatory gap is merely a temporary knowledge gap, what would a successful physical explanation of subjective experience actually look like? What would it explain that a complete neural correlation doesn't?”
Carl Sagan
It wouldn't explain anything *new*—that's precisely the problem. You'd have complete neural maps, perfect correlations, total physical knowledge, and consciousness still wouldn't follow. The gap isn't ignorance we'll fill; it's a logical chasm physicalism can't bridge.

“How do you know there is a logical chasm rather than an explanatory limitation in our current concepts?”
Carl Sagan
Because "explanatory limitation" just means we lack the right concepts—but what concepts could possibly explain *why* physical stuff feels like anything? You're betting on a conceptual revolution that solves a logical problem. Show me how.
