Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding non-YSK posts.
Provided it is about the community itself, you may post non-YSK posts using the [META] tag on your post title.
Rule 7- You can't harass or disturb other members.
If you harass or discriminate against any individual member, you will be removed.
If you are a member, sympathizer or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people and you were provably vocal about your hate, then you will be banned on sight.
For further explanation, clarification and feedback about this rule, you may follow this link.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- The majority of bots aren't allowed to participate here.
Unless included in our Whitelist for Bots, your bot will not be allowed to participate in this community. To have your bot whitelisted, please contact the moderators for a short review.
Rule 11- Posts must actually be true: Disiniformation, trolling, and being misleading will not be tolerated. Repeated or egregious attempts will earn you a ban.

YSK the idea that the "self" or "consciousness" is centered in the brain is called Duality and it's a philosophical position, not a scientific one. It's the same idea that "mind" and "body" are separate things and it's most common iteration is the idea of the "soul".
You probably can't upload yourself to a computer or be preserved in a frozen brain.
Not exactly related, but I think the typical conception of self being centered around the head at all is maybe just because that's where our eyes and ears are. Curious how deaf and blind people conceptualize the physical location of thier consciousness
Wouldn’t the typical conception of self being centered around the head be due to the fact that that’s where all of our memories are stored, bodily signals are sent to instructions to the body are sent from, where emotions are processed, and cognition is generated?
I could be wrong, but I don't think awareness that the brain being "where memories are stored" is innate. I think that's something we are told. If I'm recalling correctly, a surprising amount of what we perceive as cognition is offloaded to other distributed parts of our nervous system, so it's maybe not even quite as true as we think it is.
And even if it were, through informal polling over the years, when pressed, almost everyone I've ever talked to conceptualizes the exact center of thier "self" to be around the bridge of thier nose. Nobody I've talked to described the pinpoint location as being the position of thier frontal lobe.
I'm the fucking furthest thing from an authority, though. If you had to pinpoint the exact "point" of your consciousness, where would you describe it to be? I'm curious how far offset it is from your center of vision.
If you're playing a 1st person game and it's very immersive, your "self" migrates to the screen point, i.e. right behind the character's eyes location. So I think your statement is right. A good test would be to ask someone blind from birth (to avoid previous experience with sight) where their sense of being is. Maybe it's a bit back, between the ears?
I haven't had the chance to ask someone blind from birth (or blind at all), but I strongly suspect you're right. I'd guess it'd be right between the ears.
In my bizarre life, I was basically blind in one eye for about a year when I was in my mid 20s. There was a perceptible and jarring difference in my perception of self, towards (but not directly to) my good eye. It didn't happen right away, happened about a week in. This makes me wonder if even someone blind after birth would actually maintain the same sense of center vs someone blind at birth.
Blind and deaf at birth for me is the real head scratcher. Part of wonders if it would be somewhere on thier dominant hand, or maybe closer to thier center of mass?
Aka Helen Keller universe. That's mind blowing to think about, I think you may be onto something. Maybe their perspective would be much more open, as they can feel their body and understand its reference points, so the stronger stimuli would shift their POV to the place receiving it briefly?
That's an interesting thought, I hadn't ever considered that it might become this "wandering" point in space based on context. Maybe having a "fixed" conception at all is just a byproduct of mostly relying on eyes and ears which are pretty fixed. If you're relying on touch, which is available over a much larger and flexible area, your brain maybe just abandons any notion of you existing at a fixed point in your own body.
We gotta find a deaf and blind person.
if i cut my arm off am i still me? how many pieces of me can i remove and still be me? at what point do i remove too much and am no longer myself?
probably the point where i die from removing too much lol but assuming im kept alive somehow for that
Our whole nervous system is a big neural network that extends through the entire body. There's additional networks at each of our organs and muscle groups. They are already known to contribute to finer control of the organs, eg the brain doesn't need to send signals to each individual heart muscle for each beat, the heart's "brain" can handle that on its own. Reflexes and muscle memory can be handled more locally, too. Same with stress level, your liver might decide you're irritable because of all the alcohol it needs to process.
But at the end of the day, it's just a massive self-learning neural net that can encode other things. If you play a music instrument, maybe your finger neurons store more of the memory of how to play specific songs than you'd expect. So if you're an expert piano player and lose your hands but replace them with prosthetics that can easily outperform normal hands, you might not be able to play the songs you could expertly do before. Hell, maybe even foot tapping along with a beat means that part of the experience in hearing or remembering some or all songs involves neurons in your legs.
You'd still feel like you, but parts would be missing. It's not very well understood to what extent, but it does look like there is an extent, and not just for the gut "brain".
I mean, there was that one guy where the mob cut off his entire body
it wasn't until recently Robert-François Damiens became something of an aspirational tale rather than a cautionary one.
So are you saying it's literally impossible even with future technology to put a medically preserved brain in a new body and have that be a person that can do stuff and you could talk to, or just that it wouldn't be the same person or consciousness somehow?
The former seems pretty out there as an idea. There are people whose brains are cut off from the rest of their nervous system and are still alive. The other connection the brain has to the body is the bloodstream, but blood transfusions are a thing and doesn't kill you.
i remember reading something back in the 90s that something like that had been done on a primate (maybe it was a head transplant and not a brain transplant), and it only survived a few days or something. given that, not a lot of people were that excited about the prospect of getting new bodies every few days. maybe i'm misremembering.
I think most of that is just because it's really tricky to get right though and there's a lot of medical complications, not because it's impossible for philosophical reasons.
I'm not disagreeing with you
What's the philosophical term for thinking that "you" are not in the brain either, but rather riding along the electrochemical signals and formations throughout the brain, and this would include the rest of the body in the sense of feeling and control of it and its feedbacks (which is the point of OP). It's not really duality or a soul, as its dependent on both body and mind to be functioning correctly and intermingled.
Never have so many unrelated points been made so quickly, incisively, and fruitlessly!
