why can't Mary just look at the neural spike trains of someone seing red?

Why can't we just eat a picture of a plate of spaghetti instead of actual spaghetti? Because a representation of some thing is not the thing itself. Am I missing something?

Yes: is about a kind of knowledge.

The banal truth here is that knowing about a thing doesn't turn you into it.

The significant and contentious claim is that here are certain kinds of knowledge that can only be accessed by instantiating a brain state. The existence of such subjective knowledge leads to a further argument against physicalism.
