What- did I miss one? Was there indeed a "fatal blow" to "picture-in-the-head" in Ned Block's book that I missed? Tell me about it!
I am not claiming that physical intensity and felt intensity are the same kind of thing (i.e. merely isomorphic), they are one and the same identical thing! It is not "begging the question" to propose a paradigmatic hypothesis that is different from the standard paradigm, because that paradigm is itself merely a hypothesis whose truth has never been demonstrated to anyone!
