So, "you" would no longer exist? "You" would cease to exist, right? If you will no longer exist, then you are obviously more than your brain and body, because your brain and body is still there, right?
If your brain and body is still there, but "you" are not there, then OBVIOUSLY you are more than your brain and body, because if they were identical, then they would be inseparable.
Not necessarily. As they say, the whole is greater than the sum of its parts. A functioning brain and a healthy body combine to help form an identity, both necessary, but lacking one of them a measurable personhood identity does not exist.
Besides, technically speaking, the brain is part of the body: an organ just like the heart or liver. So, to be specific, you don't separate the brain from the body; rather, you separate the brain from the rest of the body.
I don't know at what point does personhood begins, or at what point does life begin. That is a metaphysical question that science sure as hell isn't in the position to tell us.
At least not yet.
Personhood isn't even adequately defined, yet. Kinda necessary.
Right, and if God was on trial for the "act" of creating the universe and life in the universe, I will have reasons to believe that "Goddidit", and would definitely charge him for the act. I have every reason to believe that only a supernatural Deity could have the power to create the universe from nothing and also be the initiator of time...and also have the engineering knowledge to create a fine tuned universe for life...not just any life, but intelligent life.
And based on that, I have no reason to accuse Mother Nature of such an act...I already have my suspect, God..and that is where who I am taking to court.
Well and good, but your specific God isn't on trial here.
I believe that I can, and I did. But first things first....I can say the same thing to you; unless you can show me with experimentation that the brain itself can give rise to consciousness, then the default position is that naturalism is false, because no evidence, or experimental methodology has been presented that can demonstrate it to be true.
Basically, the same thing you just told me, but reversed. You are speaking as if your position has been scientifically substantiated, which it hasn't...so you have a lot of nerve to require that of me. A lot of nerve.
And not only that, but I've asked you repeatedly to give me a natural scenario at which consciousness could have originated from preexisting material, and your response to this was "natural selection". But that isn't telling me how it is done...that is just "scienceofthegaps" reasoning, which does not fly with me.
If go back in time before there was life/consciousness, give me a naturalistic scenario at which life arose, and began thinking. So far, you've yet to do this.
Through deductive reasoning based on the information that we have (consciousness being wholly dependent on the brain, for example), we can conclude that consciousness is wholly dependent on natural processes, and thus, like all observed natural processes, arose via natural selection. Another situation is that we're still not sure if the dinosaurs died out suddenly or gradually, but we do know they died off.
Just as an accused can be determined guilty via deduction without the need of external witnesses to the act itself.
Once the mind is removed from the brain, it is no longer dependent upon the brain.
There is no empirical evidence demonstrating this, and so this notion has no place in the scientific consensus. There is no scientific consensus on whether or not consciousness can survive death, but all the indications thus far point to "no".
After all, if it's dependent on the brain during life but then somehow that dependency is removed, exactly what is the process of that?
And it certainly does not follow that just because the mind is dependent upon the brain, that the origin of the mind is from the brain. That does not follow. My car is dependent upon an engine inside of it for it to run...but the origin of my engine has nothing to do with the origin of the car, and vice versa. You can show the correlational dependence based on the relationship of the two things, but that has nothing to do with the origins of either thing. So, your reasoning is fallacious...with all due respect.
I am not my argument, so calling my reasoning fallacious is not calling me anything, or being disrespectful to my person.
With that said, your reasoning here is the fallacious one, because your using a false analogy. This is a common mistake I've seen creationists do all the time: comparing natural processes to artificial tools. (Program needing a programmer, house needing an architect, etc.) They are simply not comparable in this regard. Tools are designed with specific purposes, while biological organisms develop over time via natural selection.
Furthermore, artificial tools are static, requiring external driving forces to "do" anything. Living cells, on the other hand, are fully autonomous, capable of acting on their own without any external driving force, in addition to being self-replicating. If life can reproduce without the need of an external intelligence, why can't certain traits in life develop over time in the same way?
Again, cart before horse fallacy. You can't have consciousness without life, and you cannot scientifically prove life from nonlife...so at best, you are relying on presuppositions, as there is nothing empirically factual about anything that you just said.
The sciences don't deal in absolute, indisputable facts. The scientific consensus is the agreed-upon conclusion based on all observations and experiments, where no empirical alternatives have been proposed and reliably demonstrated as a possibility or probability. There is ALWAYS the chance that the scientific consensus is mistaken, but if it is, it's because it currently lacks the information or calculations necessary to recognize and correct the mistake.
Besides, I never said anything about nonlife. Both the egg and sperm are living, autonomous cells. Abiogenesis is an entirely different topic.
Innocent until proven guilty.
And even when "proven guilty", there is ALWAYS the chance that the accused is, in fact, innocent.
