It was edited out in the revised edition.I don't recall Dennett being abusive.
No it isn't. It's exactly the same thing.Actually, IIRC, what Dennett said was that, by definition, Mary must know her "reactive dispositions" to the colour red. This is subtly more informative than your wording.
The concept of qualia is inherently dualistic. You cannot introduce them into a materialist context and expect anything but mockery.Well, the whole argument is about qualia, so it would pretty weird if they weren't in there!
If you mean by that, that I have some grasp of basic logic, then yes.This says a great deal about your own reactive dispositions.
Nope. Qualia are explicitly non-physical.This argument resembles that of religious fundamentalists to me, Pixy. I find it closed-minded to the point of ridiculousness. For a start qualia are usually defined as the subjective components of experience, the redness of red etc, not what's left over when you take everything physical out.
Nonsense.You might construct the latter from the former but to then use this argument to refute their existence is a trick more used by extreme muslim clerics or other religious loonies.
The arguments - Searle's, Chalmers', Jackson's alike - only make any sense because qualia are explicitly non-physical. And they founder for exactly that reason: They have introduced something they have defined as non-physical into what were supposed to be reductio ad absurdum arguments against physicality.
I had nothing to do with any of this. They messed up all by themselves.
You're close to grasping the point here.The qualia refutation which I personally subscribe to is to state that subjectivity simply is data processing, and that there is no actual observer or experiencer, merely the appearance of the same.
The point is that the observer is not a thing. It's not an organ in the body or a location in the brain. It's a synthesis of mental processes. If you have the "appearance" of an observer, that means you have something that acts in every outward respect as you would expect an observer to behave.
And that means you have an observer.
