It is not an argument. It's a question, and everyone can answer how they choose.
Oh, well, in that case my answer is that the "self" and "free will" is illusion.
yet some people try to objectively explain feeling of self here.
Sidlined says the brain doesn't have any feelers. So if somebody sticks a needle in your brain, you won't feel anything. I've never had a needle stuck in my brain, as far as I know, so I can't say for sure. From this lack of feelers comes the aura of incorporeality. The "self" SEEMS incorporeal.
