And yet we are outnumbered by ants and amoebas. Are their "I's" more powerful than ours?
But the real question is, how could we ever determine whether we as a species would be even more numerous than we are at present, if we could only abdicate our "I's"?
Different species have different survival tool boxes. For ants and amoebas an important survival trait is the ability to reproduce at prodigious rates. For us an important survival trait is the ability to figure things out, especially in the context of past, present and future. This is a function of our I-ness. Having I-ness is not a necessary pre-condition for survival for all species any more than it is necessary for fish to have wings and tail feathers.
To determine the importance of our I-ness, we are best compared to those creatures most similar to ourselves – other primates. Compared to ourselves they fare much poorer in the survival game. (At least for now. Nothing is certain forever in the wide wide world of evolution). This is despite our having less effective natural defenses such as extreme strength, nastier teeth and natural fur coats. One thing we have in much greater abundance than they is extremely elaborate mental capabilities. Virtually all of the things we have and do that facilitate survival and have led to such a proliferation of our species are related to our ability to form much more sophisticated abstractions and to relate them to the real world. Everything that we lump under the broad title of civilization derives from this. Giving up any portion of our I-ness would make us more like other primates, with reduced survival rates. There is no need for context free philosophical flights of fancy here. Nature has performed the experiment.

Sounds like an argument from ignorance.
He: Everything in the world has a conscious spirit: trees, rocks, everything.
She: There are billions of rocks around. If rocks are conscious, why have we seen no indication of conscious activity in rocks?
He: Sounds like an argument from ignorance.
Of course it is not an
argument from ignorance, which relies “merely on the fact that the veracity of the proposition is not disproven to arrive at a definite conclusion�. In the case of subjectively conscious entities existing independent of brains and/or residing in rocks, no evidence of such a thing has been seen despite what ought to have been ample opportunities to do so. I could say there is an invisible dragon in every garage in the world. Should you believe this? If you do not, is that an argument from ignorance?
An argument from ignorance asserts that statement A is true because it has not been disproven or that Statement B is false because it has not been proven. I made no assertions. I asked for evidence of a non-obvious claim for which there ought to be ample evidence.

Besides, many people claim to have personally experienced an "I" (or a "thou") which, apparently, is separate from a physical infrastructure. Many people claim to have experienced subjectivity even while their brains were clinically dead. Yes, I know that materialists can always invent "just-so" stories to explain this all away, but at some point this seems to beg the question.
Please provide credible evidence of many instances of a person being clinically brain dead, as verified by the total absence for some significant time of any brain activity observed on a competently performed EEG, and who later resumed brain activity and presented credibly verified evidence that they were in fact subjectively aware during the period in which brain activity was observed to be totally absent.
The reason I ask for such elaborate conditions is that this statement has been presented to me in the past by others, on this site and other sites. Yet when I traced the links provided back to an original source, it turned out that they were talking about a case where the heart had stopped beating for a short period but the person may have remained subjectively aware. There is no reason why brain activity should always cease immediately when the heart stops beating. There was no measurement of brain activity made, this being in the middle of surgery and not an EEG recording session. Yet when the link was given to me it was represented as “the brain being clinically dead�.
But as I alluded to in my previous post, really convincing evidence would be multiple well verified instances of the survival of “I�s well after the brain is definitely and permanently dead. With all the people who have ever died, there should be ample opportunity for this, if it is possible at all. Either that or a good sound reason why such observations could not be made, although that is skating on thin ice, credibility wise.

any of our abstractions. The map is most definitely not the territory...
Our "I" is completely unlike any other "abstraction." Other abstractions are objects which we study from the outside. Our "I," by contrast, is what we experience internally, and which we use to study all other objects.
Other objects are photographs. Our "I," by contrast, is the camera.
Photographs are a poor analogy. Our memories and other objects of mentation are much fuzzier than that. If they were much sharper it would be difficult to perform the associations with similar objects that constitute so much of our mental life. How do you manage to distinguish between a cat and a dog in poor lighting at a fair distance with high reliability yet do it almost instantaneously? If you had to dredge through every memory of cats and dogs and perform some kind of similarity comparison it would take far too long. Just like it would take far too long to decide if there were a leopard hiding in that berry bush up ahead.
What we work with in our heads is ‘cut down to size’ abstractions that emphasize the similarities between dissimilar things. I imagine all animals do it. My dogs were able to immediately figure out if something was a toy even if they never saw this toy before. Even if I were trying to transfer it from bag to drawer without them seeing it. Things of interest will be recognized quickly. That is a survival trait and presumably appears in anything with a non-trivial brain. Our main strength is the ability to do abstractions at a far greater level of sophistication than other creatures. We also have a much more elaborate neo-cortex than other creatures and the neo-cortex is the part of the brain that ‘lights up’ the most when we do really abstract abstractions.
It is not that we do things that other animals do not do. It is that we do certain things so well. In particular, we form complicated feedback loops among abstractions that even other primates simply do not have enough neo-cortex to support. It is this ongoing and constantly changing set of feedback loops that constitute our I-ness. We
are our abstractions.
BYTW do dogs have “I�s? Sure seems like it. If I deny this, it is not too far a leap to denying the I-ness of other humans. Do their “I�s survive the physical death of their brains? Why not?
