Quote:The man’s name and his reasons for shooting himself— insanity? anguish? ennui?— are lost to history. But in early 1861 a Frenchman near Paris dug the business end of a pistol into his forehead and pulled the trigger. He missed. Not completely: his frontal skull bone was shattered and flipped upward like a fin. But his brain escaped unscathed. The man’s doctor could in fact see the brain pulsating through the open wound— and couldn’t resist reaching for a metal spatula. Unsure whether the fellow would pass out, scream, or perhaps convulse and die, the doctor pressed the spatula down gently at various points and asked him how he felt. Although no one recorded the answer, you can imagine what the man had on his mind, so to speak. “J’ai mal à la tête, docteur. C’est—” Nothing had happened so far, but when the doctor pressed one particular spot, near the back of the frontal lobe, the man’s words were snapped in two: he suddenly couldn’t speak. The moment the doctor lifted the spatula, the man started up again. “Sacre bleu, doct—” The doctor pressed again, and again strangled his words. This happened over and over— each press left him sputtering, mute.

Sounds pretty physical to me, Mr. "has been established". Spatula, brain, inability to talk. Physical interaction affecting mind.

The Case Of The Colorblind Painter
Quote:It is almost two years since Mr. I. lost his color vision. The intense sorrow that was so characteristic at first, as he sat for hours before his (to him) black lawn, desperately trying to perceive or imagine it as green, has disappeared, as has the revulsion (he no longer sees his wife, or himself, as having "rat-colored" flesh).
There has, we think, been in his case a real "forgetting" of color — a forgetting at once psychological and physiological, at once strategic and structural. Perhaps this has to occur in someone who is no longer able to imagine or remember, or in any physiologically based way generate, a lost mode of perception. It does not, by contrast, happen in those who have become ordinarily blind or deaf, but their cerebral cortices, their powers of inner representation, are unimpaired; it is quite different for the blind or deaf, who become not only unseeing or unhearing, but as if they had never been seeing or hearing, as did a patient with cortical blindness described by one of us (see Oliver Sacks, The Man Who Mistook His Wife For a Hat, Summit Books, 1985, p. 39).
More evidence that physical changes cause mental changes in consciousness.

So that wouldn't be a fair observation at all. It's reminiscent of when I challenged ChadWooters argument about veridicality of experience with the example of blindness anosognosia. His response was that you can't tell much from broken brains. This is precisely wrong. You can tell a great deal about ordinary consciousness from broken brains. In this case, part of the brain is missing, and correspondingly, part of the qualia is missing. The brain damage revealed how tightly connected to brain function the experience of qualia is.
