Full Idea
While it may be intuitively implausible that Block's 'mind' made of the population of China would give rise to conscious experience, it is equally intuitively implausible that a brain should give rise to experience.
Gist of Idea
The Chinese Mind doesn't seem conscious, but then nor do brains from outside

A Reaction
This sounds like good support for functionalism, but I am more inclined to see it as a critique of 'intuition' as a route to truth where minds are concerned. Intuition isn't designed for that sort of work.
