AB,
You do not need to seek information from the outside to discover the existence of your soul.
Then how would you know whether your
belief “soul” was justified? Fallacy of reification.
Why would a human soul actively need to seek evidence of its own existence?
That’s the fallacy of begging the question. What we’re trying to establish here is why you’d think there to be a “soul”
at all. Asking why a supposed soul would want to verify its own existence has no relevance to that question.
Do you honestly believe that you would have the power to seek such evidence without the divine gift of free will?
Of course, and that’s called the fallacy of personal incredulity.
Do you suppose that whatever emerges from physically predetermined activity in a material brain could choose to seek evidence of its own existence?
As that's what the only reason and evidence available to me indicates (not least because you've completely failed to produce the "sound logic" you claimed to have), yes.
Anyway – what you were actually asked and have avoided answering was, if not for the method of biology, what other method would you propose
instead to research your claim “soul”?
You were also asked by the way why, if you did have some means of justifying your belief "soul", you still know precisely nothing whatsoever about it?
