As a cognitive scientist, this is my jam. Firstly I’d just like to point out that there is no widely accepted definition of consciousness, so we don’t really know what being conscious means. There are theories, but all of them have large holes in them at the moment.
Secondly, most people report the feeling of being “conscious” but can’t pinpont how it happens or where it happens. There are some individuals in the world that have trained their whole life to better understand their body and are able to control parts of their organisms that are deemed as part of the autonomic nervous system.
There is a branch of philosophy that deals with a large chunk of what the main theories of consciousness are, but in a manner on how we experience things as humans. It’s called Phenomenology and it’s a super funky science, I recommend it to anyone and everyone interested in learning how they ‘tick’.
But yeah at the end of the day it’s an interesting thought. Personally I think the evolution of “consciousness” is due to our collective nature and that our “consciousness” at the end of our lives is the mark that we left onto the world.
Unironically since I live in the imperial core and am from an ex-socialist country, but not old enough to have experienced it. It was the Trump v. Clinton elections where I saw what lib brain does to people.
