Can consciousness exist without any brain at all?
Please do not answer with a simple yes or no, but instead make sure to provide evidence and argument to backup your answer.

I believe spiritual freedom (a.k.a. self-discipline) manifests as bravery, confidence, grace, honesty, love, and inner peace.

What does no brain at all entail? The head severed from the neck?
Humans can do without limbs but not without a head!!
But if your asking can a "dead" Human have conciousness then having no material brain is no obstacle.
There is zero proof and in fact can never be proof that the material brain is the source of life.
Matter has never been observed to turn into life,or vice versa.

Re: Can consciousness exist without any brain at all?
Consciousness cannot exist without 'memory'. And if memory (memory function) is confined within the brain, then NO, consciousness cannot exist without the brain that possesses a memory function.Scott wrote:Can consciousness exist without any brain at all?
Consciousness is the bodily (brain) experience of 'recognition', made possible by memory. --- No memory = no recognition = no consciousness.

That statement appears to be ipse dixit.
Nonetheless, I have just now made two more topics to explore the idea:
1. Consciousness as the bodily experience of recognition, made possible by memory?
2. Does consciousness require memory?

To be conscious means to be aware of Environmental and Organic stimuli.The rest of our mind properties (reason, memory, pattern recognition, symbolic language etc) enable the introduction of content in those conscious states (introduce meaning,concepts in the form of thoughts).Scott wrote: ↑July 15th, 2021, 11:56 am Sometimes there will be news headlines about someone living with "no brain" but actually the person has 10% of a brain left or such, so in those cases the news headline is using hyperbole, if not being outright dishonest.

The basic state of conscious processing is achieved by the ARAS which is located low in the brain stem. The Central lateral thalamus plays a key role in connecting the brain stem with the rest of the brain modules responsible for all the above mental properties.*
So as long there is a brain stem, neuroplasticity "reshapes" the remaining available parts of the brain so that they can provide the content (previous experiences, symbolic language, reasoning)which it was previously provided by typical areas of a human brain.
So based on our current scientific knowledge about the brain and how those states are achieved, the brain is sufficient and Necessary for conscious states to emerge.
It is reasonable to conclude , based on objective scientific evidence, that conscious states can not "exist" when all the parts of a brain are missing.

Re: Can consciousness exist without any brain at all?
Does this person/creature have, er, something that might fulfill some/all of the functions of a brain, even though it isn't a brain? Or are we considering something quite ... alien?

No brain means empty skull. That is, everything above the spinal cord is missing.Protagoras wrote: ↑July 15th, 2021, 12:07 pmWhat does no brain at all entail? The head severed from the neck?

So the person didn't know or feel they had an empty dull?
The CT shows empty space!?

There are no known cases of conscious persons with empty skulls! Persons with empty skulls are dead.Protagoras wrote: ↑July 15th, 2021, 6:33 pm So the person didn't know or feel they had an empty dull?

There are only living persons with more or less incomplete brains, but not having a whole brain is not the same as not having a brain at all.

Re: Can consciousness exist without any brain at all?
So how does one know whether a brain is incomplete using a CT?
Compared to what is it incomplete?
Or is it just small? Or?
