Lance, this is just FYI. Radical Eliminativism means that phenomenal mental states have no causal power. But they actually do and this is testable. Below an idea of psychological test of kind I use when I speak with R.E.-sts.

I am now addressing you as an Observer who “sees the light.” Suppose I inform you that starting tomorrow your “inner light” will go out. How exactly this happens is not so important. Almost every person has experience of falling asleep, has experience of being in a state of hypnosis and anesthesia (this is not the case for everyone, that’s not the point). Your “inner light bulb” will go out and “you” will disappear completely. No dreams, no worries or awareness. You won’t even know that something happened, just as the sleeping person doesn’t know. And there will be no transition process such as falling asleep. Your inner light bulb will go out forever. You will never “wake up” again. However, from the point of view of an outside observer, little or nothing will change. Your body will still communicate with the same people, go to work, pay taxes, engage in “Strong AI”, etc.

The question is: did you feel _scared_ even for a moment? Just a little bit? The answer must be honest.

Emotion of fear to lose the "inner light", that technically can be measured objectively, is a clear sign that corresponding phenomenal metal state has causal power. This test is a necessary but not a sufficient condition for metaphysical consciousness. Reports of this kind can be built up, so if a computer generates it, it does not necessary mean the computer is conscious.

Chalmers says that's the best argument against strong illusionism, but he doesn't actually claim it's a good argument:

"Dialectically, the illusionist side is much more interesting than the realist side. Looking at the dialectic abstractly, it is easy to sympathize with the illusionist’s debunking against the realist’s foot-stamping. Still, reflecting on all the data, I think that the realist’s side is the right one."
