Mary is presumed to have all objective knowedge and only objectve knowledge, Your phrasing is ambiguous and therefire doesnt address the point. When you say Mary will know what happens when she sees red, do you mean she knows how red looks subjectively, or she knows something objective like what her behaviour will be.....further on you mention predicting her reactions,
Is that supposed to relate to the objective/ subjective distinction somehow?
So? The overall point is about physicalism, and to get to 'physicalism is false', all you need is the existence of subjective knowledge, not its usefulness in making prediction. So again I don't see the relevance
Maybe. I don't see the problem. There is still an unproblematic sense in which Mary has all objective knowledge, even if it doesn't allow her to do certain things. If that was the point.
If one of Mary's predictions is, "When I see red, I will say, 'wow! I didn't know that red looked like that!", then the fact that she has predicted this in advance is hardly evidence that she does not learn anything by seeing red. If anything, it proves that she does.
I think your post seems to have been a reply to me. I'm the one who still accepts physicalism. AncientGreek is the one who rejects it.
I realize that. A reply doesn't necessarily have to be an argument against the person it is a reply to.
