dhw: I have no idea what the “quantum mechanism” is, but since you say the s/s/c is the same in life as in death, it clearly makes no difference to the argument. In life and in death, the “quantum mechanism” of the s/s/c is the THINKING mechanism.
DAVID: But its interface in life and death is different, and i suspect the mechanism differs also to fit.

dhw: Of course the interface with an immaterial world will be different from the interface with a material world, and of course you will no longer have material means of expression and communication. There is no longer a brain mechanism! That is why dualists believe that there is an immaterial s/s/c that works with the brain in life, but the same s/s/c separates from the brain in death, and that is the THINKING you.

I agree.


DAVID: Yes, thinking, but in two different realms.

dhw: That is what I keep telling you. The SAME THINKING s/s/c in two different circumstances, or realms if you prefer. And so a dualist cannot insist that thought is impossible without a prefrontal cortex.

If you accept the two realms, a person cannot think in life unless his cortex is functioning. That is the only point I have been making


DAVID: She is correct in her description about cabbies. I've read the study in the past. As a storage area it had to enlarge. You are comparing her memory areas to cortical thinking conceptual areas, which is where Einstein genius is.

Is it? March 7:
dhw: So Einstein would still be a genius in an afterlife without his prefrontal cortex.
DAVID: Of course. You’ve gotten my concept.

dhw: So your concept is that Einstein could not be a genius without his pfc (because according to you intelligence springs from the s/s/c being able to use an advanced brain), but he can be a genius without his pfc provided he hasn’t got a pfc.

The point of the cabby and musician references is to show that thought enlarges the brain, and the brain does not enlarge in anticipation of thought. Since this applies to the hippocampus and to the auditory cortex, why should it not apply to other areas of the brain as well, such as thought expanding Einstein’s pfc and the brain of pre-sapiens?

The hippocampus is a storage area for memory and the auditory area also for the musician. Einstein was an amazing genius with a huge concept area, that I am convinced he was born to develop and allow his concepts to appear. His hat size was not extraordinary. The brain is very soft fatty material and can give room elsewhere which would allow for his large areas without pressing on the skull. Brains with very high IQ are different.
