Good article. Except for the "qualia" asides. Really there is no such thing as qualia. There is nothing to explain, there is no "explandum", so to speak. There is no such thing as "redness", there is only the fact that a human subject will use the word "red" to refer to an electromagnetic pulse of wavelength 600nm. The subject will say "red" to relate the wavelength, that is, we can predict the subject will say "red" if asked for the "color" of a pulse shone at the subject of wavelength 600nm. There is simply nothing to explain in qualia, it does not exist.

To steal from Dennett, one might as well ask about gremlins that appear in the cylinders of a combustion engine. We can explain the fact that wheels move in a combustion engine via the action of the cylinders, or, we can say it is the action of the cylinders plus the gremlins. Thinking of qualia as something that needs explaining is like thinking that your car's movement is predicated upon the gremlins produced in its cylinders. The gremlins do not exist, neither does redness, nor any other type of qualia. Period.
