Good Morning,Mr. Savage!
- As we've agreed, a loaf of banana bread is not analogous to a brain.
I wonder if you would be so kind as to point out precisely where "we" have "agreed" to any such thing.
A loaf od banana bread is, in fact, usefully analagous to a brain, or a neurosystem--as long as one understands what an analogy can, and cannot, be used to demonstrate.
For some reason, the brain has an emergent property of consciousness, and consciousness naturally involves what we call an “identity” – or at least, the illusion of an identity, the illusion of a continuous “self.” A loaf of banana bread does not involve this emergent property. This is what makes the difference.
For some reason, a loaf of banana bread has an emergent property of cake-structure, and cake-structure naturally involves what we call "fluffy-brown-fragrant-deliciousness", or, at least, the appearance of "fluffy-brown-fragrant-deliciousness", the illusion of being a loaf instead of an assemblage of mashed bananas, spices, leavening, and flour. A neurosystem does not involve this particular emergent property of "fluffy-brown-fragrant-deliciousness". OTH, "fluffy-brown-fragrant-deliciousness" is, in fact, a useful
analogy for consciousness, in that none of the ingredients of banana bread exhibits "fluffy-brown-fragrant-deliciousness"; it is instead a property that emerges from a specific set of circumstances involving all of the ingredients of the banana bread, combined and treated in certain ways.
None of the "ingredients" of a neurosytem exhibit, consciousness; it is instead a property that emerges from a specific set of circumstances involving all of the components of the neurosystem, combined and treated in certain ways.
- We’ve been assuming that a perfect replica of the brain would not replicate that identity.
No, not really.
You may have "assumed" such. Others have pointed out that, although a perfect-enough "replica" or "duplication" or "copy" of your neurosystem is physically impossible,
IF such a"duplication" or copy" or "replica" of your neursosytem were made, and activated, at the moment of activation it would exhibit the emergent property of a "replica" or a "duplicate" or a "copy" of the consciousness emergent form your neurosystem, until the instant the experiences of the "copy" or "replica" or "duplicate" diverged in any way from the "original".
The preoblem with your scenario (in addition to its physical impossibility), is that
neither of the consciousnesses so emergent would exhibit the slightest semblance of "immortality".
If my brain is perfectly replicated after I die, my identity will not return to life – or, so we assume.
Your wilburing of "assume" seems to indict that you are about to (finally) present evidence to the contrary. Let me pour a cup of coffee.
--I'll be back.
.....................
OK. Fortified with a cup of Tanzanian Peaberry (full city roast), we forge ahead.
- But again -- that doesn’t seem to jive with your claim that every aspect of my particular sense of self would be replicated by replicating my brain. My identity must be an aspect of my sense of self, and we both assume that my identity would not return if we were able to perfectly replicate my brain…
How disappointing.
Oh, well.
Your identity/consciousness/observer/PSoS is NOT an "aspect" of your PSoS/soul/consciousness/identity; they appear all to be wilburs for the same emergent property of your neurosystem and its hypothetical duplicate/copy/replica.
"You" would not "return" if your neurosystem were "duplicated" or "copied" or a "replica" were made of it.
OTH, if the duplication or copying or replication were, in hypothetical fact, perfect, neither of the consciousnesses/souls/selfs/identities/PSoSs would be able to tell "which twin was the phony", so to speak. If they were, in fact, identical, they would share the conviction that each was the "real" you.
Two identical loaves of banana bread would, in fact, share the identical property of fluffy-brown-deliciousness.

I wonder if we might begin to consider your evidence that the "soul" exists, and is "immortal"?
