there might also be a substantial fraction dissenting on the grounds that some of the key notions are ill-defined; for instance, that we don't really know what "conscious" means beyond the fact that one particular bunch of things -- namely, us -- seem to have it; or that personal identity is fuzzy and in putative cases of "resurrection" there really isn't a fact of the matter as to whether the "before" and "after" are actually The Same Person.

I'm not sure I agree. "Consciousness" strikes me as being as well-defined as concepts like "anticipation" and especially "experience" that are used in the foundations of empiricism.
