AB,
In the absence of any feasible definition for what comprises our conscious awareness or how it works, I would say the onus is on you to demonstrate how conscious awareness emerges from physically predefined reactions of material elements.
Wrong again.
First, there are several "feasible definitions" as you put it. What we don't have yet is a complete
explanation.
Be nice if you could at least get that right.
Second, consciousness as an emergent property of brains is consistent with what's known already about emergence as a phenomenon. There's no particular reason to think that consciousness can't fit that model however much you assert it to be otherwise.
Third (as with your every other attempt at logic) you fundamentally misunderstand the meaning of "burden of proof".
You're the one who keeps telling us that consciousness arising naturally is "impossible" - it's
your claim so it's
your job to demonstrate (rather than just assert) it.
I did incidentally offer twice recently to explain to you the basics at least of logical argument. Typically you just ignored the offer, but in doing so you condemn yourself to making howlers like this over and over again.
Does that not bother you at all?
