But the suggestion that I and you don't exist is absurd. — Ludwig V
It isn't that 'I' or 'you' don't exist; rather, the identity that I have doesn't occupy a specific region of the brain called "the self" -- at least they haven't been able to find it, and they've been looking, What seems to be the case is that various facilities in the brain maintain our identity as a seemingly solid self.
If it's a fiction (which wouldn't be my choice of words) then it's a fairly solid fiction in a healthy, intact brain.
Why do you separate composing from typing? — Ludwig V
Several different areas of the brain are involved in composing this sentence. Obviously Broca's area, (language production) is involved; thought creation areas are involved; memory, etc. None of these areas control motor functions (like typing). So, once the sentence is ready, the motor centers are in charge of the typing.
Granted, the brain has some degree of plasticity, and an unused area can be recruited for some other purpose, but in adults, especially, this isn't a quick process. For example, were I to be blinded, the visual cortex would have a lot less to do. It might be recruited to process sensory input from the fingers in order to understand braille.
The idea that saying something is somehow unspooling what the brain has already done just pushes the issue back a stage into an infinite regress. — Ludwig V
There isn't "something else unspooling what the brain has done". The brain itself is managing the process of issuing a statement from inspiration to expression. Broca's area alone can't produce speech without coordinated effort by the motor system controlling tongue, lips, jaw, and breathing. Brain injuries and brain manipulation (during surgery) reveal that different areas of the brain control different aspects of our whole behavior.
I don't think the brain thinks. I'm the one who does the thinking. — Ludwig V
That's why I asked, "who are you?"
No matter what you say, what you think, what you do, it issues from the brain labeled "Ludwig V". What the neurological researcher is saying is that the "
representation called the self of Ludwig V" is not doing the thinking, Almost everything the brain does is silent; we don't hear it thinking. We can't watch it retrieve a memory if a grade school teacher; we can't observe it coming up with a new idea. It feels like "we" are doing the thinking, but that's part of the fiction of the self.
Ludwig:
Your brain is doing
your thinking, it's just that "
your thinking" happens in
your brain below
your radar.
Hey, show a little gratitude. The brain controls everything about you from your happy smile to your asshole and everything in between. You don't want to know everything your brain is doing. Yes it does your thinking, which you want to claim. Why don't you claim the task of keeping yourself upright when walking; blinking regularly to keep your eyeballs moist; keeping track of your temperature, blood pressure, heart beat, and breathing; waking up every morning (rather than not waking up); registering a patch of itchy skin; and hundreds of other services going on all the time?
You don't claim all these functions because you probably feel thinking is more noble and important than managing your bladder and rectal sphincters. Well, Ludwig, just wait until those bladder and rectal sphincters stop working, and you'll no longer consider their control beneath your dignity.
Thinking is just one of many things that we are not 'personally' responsible for.
