Really? How do you define “natural”? That which be seen, heard, tasted, smelt and touched? Thoughts, feelings and decisions are not natural because they are intangible! Where are you located? Inside your skull?
Yes. Inside my cranium is precisely where I am located.
If you were located inside your cranium you would have no self-control! All your activity would have physical causes. You wouldn’t be able to think for yourself. You would just be a brain, a lump of tissue, a biological machine… And in addition to being a mindless body you wouldn’t even have a self because a self is intangible…
I am a biological machine, a self motivating automaton. So are you. So is everyone. It’s only human ego that tells us otherwise.
If you’re a biological machine you cannot think for yourself, make any decisions for yourself or be responsible for anything you think, feel, decide or do. How does it feel to be an impotent robot?

BTW How can you be self-motivating without a self?
Evidence of that can be found in examining changes in people with brain damage caused by injury or illness.
It is not evidence at all. It merely demonstrates that the brain is the mechanism by which we communicate and control our body. Are your thoughts, feelings and decisions tangible? If so let us know precisely where they are located and how they can be observed…
They’re emergent.
You think using a word solves the problem? If it were true it would merely demonstrate that your thoughts are merely valueless electrical impulses. If nothing but matter exists nothing is significant…
