I don’t understand well your position.
By “mind” and “mental processes” I mean thoughts, emotions, dreams, memories, fantasies.Do you consider these as metaphysical or mysterious? Or metaphorical?
Next, do you view our mental processes as
(2) identical with the brain
(3) caused by the brain
(4) something else
The three options are mutually exclusive. If something is non-existing, it cannot be the brain because the brain exists, and it cannot be caused by the brain (if A is a cause of B, it must be that A exists, otherwise how can you say it is an effect that is caused ? ). And, if something is identical with the brain, it cannot be caused by the brain since something cannot be the cause of itself (A cannot be the cause of A ).
If our mental proccesses are caused by the brain, they are not the brain but existing things that are different from the brain. I don’t think you can escape the logic.
Then I can argue for dualism :
Iff you agree with the logic, so far, then I can ask “if we agreed that a dream is caused by the brain, but not identical to the brain, what stuff is a dream made of? “. If you say “it is made of atoms”, I will ask “is it made of the atoms of the brain, or of other atoms” ? If you answer “of other atoms”, you have to show which atoms is a dream made from if not from brain-atoms. If you answer “of brain atoms”, you contradict yourself, since you already agreed that a dream is not identical with the brain, only caused by it. Then it leads to the conclusion that a dream is not made of atoms (though it might be caused by them), and according to most definitions of material, would not be material (since it is not made of atoms). (Though, I wouldn’t say that it is “supernatural” ).
I think that dualism is a defendable position.
(I did not mean to go into it, when posting, but these are the assumtions my question is based upon).
