I should add that if we accept that the question, "Are others' visual
experiences the same as mine?" is meaningful WITHOUT having to define
"visual experience" in terms of physical facts, then this suggests
that, as Dave Chalmers puts it, the experience of redness is a FURTHER
FACT beyond the physical facts.
