The burden of proof lies with you.
Can you offer a logical explanation for a single entity of awareness to exist within material reactions?
So your total ignorance of logic is once again on display. This is a textbook
argument from ignorance.
Argument from ignorance (from Latin:
argumentum ad ignorantiam), also known as
appeal to ignorance (in which ignorance represents "a lack of contrary evidence"), is a fallacy in informal logic. It asserts that a proposition is true because it has not yet been proven false or a proposition is false because it has not yet been proven true. This represents a type of false dichotomy in that it excludes the possibility that there may have been an insufficient investigation to prove that the proposition is either true or false. It also does not allow for the possibility that the answer is unknowable, only knowable in the future, or neither completely true nor completely false. In debates, appealing to ignorance is sometimes an attempt to shift the burden of proof.
You claimed "It can be argued that it is logically impossible for a single entity of awareness to exist within discrete material reactions." That is
your proposition, not mine. I don't even know how you intend to
define a "single entity of awareness", for fuck's sake!
I also went to the trouble of explaining the problem with showing,
even in principle, that something is
impossible in physical terms because of the problem of the possibility of unknown physical processes. That seems to be something else that you just decided to ignore, or perhaps, it went way over your head...?
How can any credibility be given to the output from a material brain driven entirely by unavoidable physical reactions to past events?
Again, I have no idea what you think the problem is. Why not? Brains have evolved to be reasonably good at thinking, just as hearts have evolved to be reasonably good devices for pumping blood. Brains have also benefited from cultural evolution and hence the work of previous generations.
What's the problem?
And, of course, it's
irrelevant because it is you who is trying (and spectacularly failing) to show that it's
impossible. Even if my answer was "I have no clue, it's a total mystery", you
still wouldn't have made your case for god-magic.
You really do have to get it into your head that YOU are trying to prove something. It is therefore entirely up to YOU to make the case. Nobody else has to prove anything.
