like the brain is literally encased in the body so how can it be separate? like if you go around licking lamp posts you're going to pick up some germ that's gonna make you feel like crap and you get insomnia or fever and your brain will definitely be impacted. and so you'll have short temper and that'll get you into trouble.

The real flip side of your question is: do you think you'd still be you as a "brain in a vat" without any body?

Ultimately this whole discussion boils down to challenging the definition of "you" or "I". Biologically every "singular" person is the result of many living things working together, so the concept of "I" is an illusion. Physically, there is no "I", but only "us".

This makes the discussion easier. If the hand is removed, then of course "we" are different because "we" lost a piece of "us". This would also be true if "our" brain was removed.

Nevertheless, there have been cases of brain dead people's body adapting to the lack of central nervous system, so the body is more independently alive than we tend to give it credit.

We're they on life support, or do you have an example of it happening without any outside assistance?

so the body is more independently alive than we tend to give it credit.

Being able to biologically adapt to a different control mechanism is cool, but it's not necessarily 'alive' depending on your definition. The biological mechanisms may still fire, but that doesn't mean that you're doing anything more than keeping a meat sack functioning while it otherwise atrophies.

You are correct, the person was on life support. But they grew and went through puberty like any other normal functioning human. (I believe the person was born brain dead, and the wealthy parents couldn't let go so they kept the person on life support at home).

Cells are living things by definition. So it is alive, though the body functions more like a tree than a mammal at that point. But a decentralized nervous system grew around the different vital organs.

Why not? When I am asleep, I consider myself to be me but asleep.

All language breaks down under scrutiny.

Oh please. Nice words and all, but if you fall into a ditch, you don't say "well, shit, we're fucked!" like Gollum. You feel like a single entity in trouble. You don't say "my dear neurons, gut bacteria and anus cells, let's work together to get out of this mess!!"

[–] reliv3@lemmy.world 2 points 1 day ago (1 children)

You truly believe the semantics of the English language disproves the point? English and the way it defines "I" is greatly affected by things seperate from biological definitions (one being the spiritual concept of the "soul")

Also, there did exist languages in other cultures that did not have the same concept of "I" as the English language. Your counter-argument is very weak.

[–] elbarto777@lemmy.world 1 points 13 hours ago

I used an example in English because we're discussing in English, not because of semantics or language rules. My counterargument is fine.

But you made me wonder, is there a human language on Earth in which an individual refers to themselves as "we" instead of "I" - or yo, je, ich, watashi, etc? That would be fascinating.

Or what are those other languages that have a different way of using "I", which I'm assuming you're referring to as the pronoun to refer to oneself?
