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.
Your real question is a bit of an emergent property. Willpower, patience, agency, etc. are concepts abused by authoritarian right-wingers to distance themselves from responsibility and project it upon those they have power over. In this process, those who are abused are forced to identify with a separated, mystical entity they call “brain” that is different from what it really is. And we only have control over 10% of it lol
yeah i definitely see that but i do see the free will thing come up everywhere tho
