What would it mean if they were all to reveal that they lacked consciousness? Is this the same as a blind person revealing they can't see or is it categorically different?
This is the whole argument ... just as in NDEs - how do you even know the brain has stopped functioning if we can't reliably "detect"/"measure" consciousness? - what if we prove at some point that consciousness
can't be measured? Or even that energy levels low enough to sustain an NDE aren't currently detectable? How would a case of having a real NDE differ from one in which experience is constructed after consciousness is regained? Perhaps there is a way to measure physiological changes and some pattern would emerge but then you could just say there was some very low level of activity or some as yet undetectable physical something at work -
Here's the gold standard - platinum, even, to show that the brain is in the same physical state, down to the lowliest whatever fundamental particle configuration (or to whatever scale differentiable consciousness could be attributed (hypothetically) and yet two different p-states are reported ... 1) how would you definitively show it? and 2) just think what it means if two different states are then reported ... ? Do current experiments show that when region A-1 is stimulated grandma's biscuits are reported in
exactly the same way, or do they sometimes have gravy on them (I hope there is gravy!) ... too crude probably but you could argue that either thesis is supported ...
This is what I was trying to get at ... there don't seem to be any clean cases in which a non-physical consciousness looks different from a physical one, or any scenario under which a physical cause couldn't be hypothesized (and that has some implications, I think in any/all other areas) ... so perhaps your job as author is to come up with a world in which consciousness is non-physical and the reports from this scenario above lead scientists to a troubling conclusion ... perhaps it
is physical after all ... or, you know, vice-versa, it's your story, after all. ;-)
How would a nonconscious species know they were or weren't conscious or that another species was or wasn't conscious? And vice versa.
How do
we know? Would you be surprised by future science if a fair percentage of the population was found to be devoid of conscious experience, not outwardly visible? There seem to be people of any other variation - those without imagery for example ...
Maybe they could be required to wear a little symbol to indicate, you know, so we would know better how to interact with them, in the proper way ... like a "C" with a line through it, in some kind of eye catching design (color) or maybe when you approach, the relative levels of consciousness could be indicated electronically ...
yes, many possibilities here ...
