How many times does it need pointing out that brain agency is not my conclusion but a universally accepted view held by researchers?
No such universal view exists in any field.
If it did the field would go nowhere. Wait a minute.....maybe you're right.
Of course there is a religious minority who hold to ideas such as quantum consciousness, universal consciousness/mind, etc. But it is these beliefs that are neither supported by evidence or accepted by the majority of researchers.
The majority of researchers have often been wrong. And no researcher can explain which specific activity of the brain is resulting in consciousness.
Nothing is settled as far as it's production. NOTHING.
And monkeying around with the brain tells us nothing beyond normal brain function is necessary for the expression of consciousness. It tells us normal brain function is one thing involved. It CAN'T tell us everything that is involved. Only fully understanding how it arises can do that.
You do not understand the limits of what current research can demonstrate. You do not understand logic.
And you are unable to defend anything.
My opinion: The reason neuroscience has not been able to explain one thing about the process that produces consciousness is because they are not looking at the right things.
It is as simple as that.
The answer is not in the macroscopic workings of the brain, but much deeper, much smaller.
There is the possibility it is beyond our abilities to observe.
