It is not just limiting it. It is changing it. That is what current brain research into brain damage reveals. You are saying that this damage is undone when complete damage is done. That makes no sense.
In regard to the idea under discussion, if consciousness is not a creation of the brain, the experience of form would change it in the sense that it would gain knowledge through that experience inclusive of any and all limitations experienced.
You are forced to retreat into treating this substance as something else which combined with the brain makes consciousness. Basically a catalyst but without the brain it is nothing.
So one explanation is that brain+mystic goop = consciousness
or
brain = consciousness
You have all your work cut out for you as Mr. Occam keeps slashing you.
For some reason you have decided to add something else to the discussion so the equation becomes X + biological form = consciousness.
Essentially what is a brain or body without consciousness?
The discussion has been about
1: Consciousness is not necessarily an emergent property of the brain
(Consciousness + human form = conscious human experience)
2: Consciousness is an emergent property of the brain
(Human form + human brain = conscious human experience)
"mystic goop" has not, until now, been mentioned. I am unclear as to how you have decided to include it.
You have to show something that would not make sense if it is the brain alone but since this material seems completely tied to the brain I don't see how you can.
As has already been said, there is no way to know whether or not consciousness is an emergent property of the brain or something which has always existed even before form, any more than there is any way to tell whether the universe exists as it does of its own making or an outside influence has contributed to its existence.
Essentially that is why people can and have for centuries argued in circular fashion about it. There is no known method of science which is able to end the argument.
My present position regarding the argument is explained in post
#100 of this thread.
My position is legitimate and in regard to Friar Occum's wisdom that among competing hypotheses, the one with the fewest assumptions should be selected, the selection in the case of [2:] is assumed the best selection for the purpose of getting on with the actual individual human experience and seeing where it goes in between the advents of birth and death...which is not to say that the selection has to be believed and religiously held as the truth of the matter,(to end all argument) because the assumptions [1 & 2] are equal.
This is because physical observation of brain activity in relation to consciousness does not (and can not) prove therefore that
consciousness is the sole creation of brains. What it proves (and therefore is not assumption) is that there is correlation...what it shows is that human action can be seen to correlate with brain activity...(and why would it be any other way?)...no surprises there right?
That the brain creates consciousness...well therein is the assumption.
That the brain/body facilitates consciousness...well that also is an assumption.
Hence 'the argument'.
