Sorry, but I always get a little annoyed when someone I'm dealing with starts insisting on a double standard, even if they're smiling while they're doing it (actually, especially then).
That's a rather sweeping statement for someone whose merely "seen some claims".
First I used the word "often" to be careful and polite, and you pointed it out and criticized the use of the word often, so I was a bit more straightforward and said that to my knowledge, there never has been one, and now you criticize it as a sweeping statement.
I'm not sure what you're looking for there.
No, you haven't. All you've done was demonstrate a relationship between consciousness and the brain, which is something no one is questioning.
*See previous comment.
There's also no known structure in the brain that creates consciousness.
Ah, I see your point: if we haven't figured out how to measure or describe something, it must not exist, even if we can see that it does.
Uh huh. There's also never been documented or rigorously scientifically verified case of radio waves being detected without some sort of equipment.
I think you're refusing to, but that's OK.
Everything he said is predicated on the belief that consciousness is a product of the brain. Asking "how do we know it is" is not an extraordinary claim. It isn't a claim at all, it's a question.
You haven't demonstrated how we know that consciousness is produced by/in the brain, you've only explained why you believe it is.
And I've already granted that it's non-falsifiable. But considering I've seen no evidence put forward to the contrary, why should I consider otherwise?
This is more than just evidence of a relationship. It's evidence of causality. Doing things to the brain can change, reduce, or temporarily or permanently eliminate our consciousness.
-
Eliminate: People can point out that during certain times, due to injury or chemicals, their consciousness was temporarily completely gone. But you've again shifted towards non-falsifiability by suggesting that consciousness existed during that time, but we just can't remember.
-
Reduce: Instead of being completely eliminated, consciousness can be reduced by altering the brain. There is a whole spectrum of states between wakefulness and complete unconsciousness. Your defense against this as far as I can tell was to propose that the brain is merely the tool or expression of consciousness, and affecting the brain affected consciousness. But, if consciousness can't be created or destroyed, where is the remaining consciousness when a fully conscious person has their level of consciousness severely reduced? The statement about not-remembering isn't really applicable anymore.
The straightforward causality, combined with absence of evidence for other alternatives despite considerable research of the brain (no known structures to receive external consciousness, nothing known on the molecular or atomic level to produce consciousness), makes a very compelling case. What other valid hypotheses should Hawking or others consider?
Furthermore, you said that everything he said is predicated on consciousness being a product of the brain, but this is not precise. Everything he said is predicated on the belief that the
mind is a product of the brain. Mind includes a lot more than just consciousness. Although definitions sometimes vary, a mind includes consciousness + intellect + memories, and sometimes also personality and emotions.
If we agree to view consciousness in accordance with the wave/ocean scenario for the sake of argument, then it would be reasonable to assume that consciousness would only be capable of manifesting itself in the brain to whatever degree the brain is capable of accommodating it. What I mean is, going by the ocean/wave of consiouness example, if the wave could talk it would be saying to itself, "Now I'm a wave, now I'm the ocean, now I'm a wave, now I'm the ocean....." the "I" may not be so much defined by the limits of it's dwelling place as confined by them.
This doesn't follow the conservation of consciousness you suggested earlier. Do you intend this to go along with that, or is this a separate hypothesis? This doesn't hold to conservation of consciousness. Rather than the ocean becoming a wave, it's becoming many waves. If each wave contains the whole ocean, consciousness is not being conserved.
Because, as many Eastern philosophical descriptions of reality maintain, and as quantum physics is beginning to suggest, the conglomerate unit may be a macrocosm of all the tiny microcosms. In other words the "I" blueprint of a structure may be imprinted on each and every cell that comprises that structure. Genetically speaking, we already know that it is in the individual DNA of each cell.
I'm not sure I understand what you mean here. Can you clarify?
Are you saying that, like all the cells have DNA for the whole body in them, that each person has information for the whole universe in them?
Exactly (see above).
I think you're expecting too much from the metaphor.
Expansion and dispersion aren't necessarily mutually exclusive conditions.
I'm not expecting too much from just the metaphor- I'm expecting much from the metaphor combined with your explanations.
On one hand, you've basically been suggesting the possibility that the brain is just a tool or physical expression of consciousness, so the reason it's possible to alter consciousness by altering the brain is because, somehow, consciousness is using the brain rather than the brain producing consciousness. And you've suggested that when we sleep, we're not really unconscious, but instead we're in greatly expanded consciousness but just don't remember it because our memories are in our brain.
On the other hand, you're suggesting that after the brain dies, the "I" is greatly expanded. Again, I don't really see why this would be the case, as I've explained above. Why isn't the "I" just dispersed without expansion, if consciousness is conserved? Why would the conglomerate receive a continuous afterlife rather than individual cells receiving continuous afterlives? In addition, if things like memories, ability to process information and be intelligent, and the ability to feel emotions are all products of the brain, what sort of meaningful existence would a dispersed consciousness hold? In what way could it be considered a heaven in any way? If the brain is so important for consciousness, why wouldn't discarding the brain greatly hinder it?
