My oh my. There saeems to be a lot of this discussion (from all points of view) based on a measurable and mathematical/physiological model. The problem I see with this is the discussion centers around that which cannot be measured, and is observed only by inference by/in people who claim to be spiritually blessed, in any way.
To look at the physical model, anthropologists,sociologists and biologists all seem to think that man’s self awareness is what sets him apart from other animals; that this self awareness is generated by a lrge cerebral cortex and its ability to override the primitive ‘lizard brain’ or at least modulate its responses, and make more meaningful decisions. When man evolved to a point where the cerebral cortex was able to process information in an abstract way, that triggered his ability to start to think of himself as an entity with choices and an ability to wonder about the rightness of the choices. And so self awareness developed and began to evolve to the complex creation it is today.
Now, we cannot see, touch or smell this self awareness, yet we can infer a creature has it by its behavior. By the idea that , as mentioned somewhere earlier, if we were all ‘hard-wired’, we would always respond exactly the same way to exactly the same stimuli. Yet we clearly do not–what is the difference? Learning? certainly, to a point, but dogs do that, too, yet all bio/anthro/etc-pologists agree that dogs are not self aware ina human sense, so…what else is there?
There is an as yet undefined way the brain works to generate this self awareness, and it is clearly linked to the large cerebral cortex that humans have, according to the research I have seen. There is even some suggestion that dolphins may have the beginnings of this awareness, but that is still pretty edgy.
By the same token, can not the soul exist in an as yet undefined way, linked to a being that has a spiritual sense of itself? As we are aware of ourself, as we have what psychologists call a ‘watcher’ in our consciousness, and we converse with it, yet it has no specific neurotransmitter linked to it (yet), can not the soul exist in a person, interact with them, give them a sense of guidance and purpose in the world, or direct thier seeking, in ways that cannot be measured?
I say yes, we have souls, they are a better aprt of us, and good luck in finding where they reside.
