The problem with this line of thought is that consciousness can be damaged when it's physical container is damaged. A piece of falling masonry can be enough to shear off large parts or all of it. If consciousness was fundamentally distinct, this wouldn't be the case, would it?

[hnfong]

There is a "The Matrix" (the movie) argument where we posit these:

1. Whatever you believe is true is true (this is how the consciousness builds worlds before there is any physical existence)

2. Our consciousness built the physical world and runs it like a simulation.

3. The reason our minds and consciousness are highly correlated to the physical situation is to make the simulation feel real. It's a specifically designed feature that to a large extent synchronizes the "host" and the simulated objects so that despite being outside of the simulation, the "host" feels like they are inside the simulation.

4. The corollary to 3 (and 1) is that if you are damaged or die in the simulation, that effect is mirrored outside the simulation too (to some extent).

There is no problem here. [I may have shared this thought experiment before here using a different handle.]

Let us assume there exists in our planet an undiscovered island that has developed independent of other human societies. This is not an island of primitives. The inhabitants pride themselves on their scientific and empirical approach to knowledge acquisition, however they are not quite on par with the rest of the planet in terms of scientific knowledge and technology. Specifically for our purposes, they have not yet discovered Electro-Magnetism.

Now assume somehow (via a shipwreck, or whatever) these islanders come into possession of advanced transmitter/receiver communication devices, and we'll assume they are in working condition and have some sort of power source (magical internal or solar or whatever - they can be turned on).

As the scientists on this island fiddle with these boxes, they notice that certain configuration of the device interface will cause it to 'emit voices, songs, and music'. Various knobs seem to change the voice, etc. Further experimentation and they discover that speaking to the device under certain configuration seems to establish a sort of 'communication' with the box. After these blackbox approaches, they start taking apart these mechanisms (while they are turned on). Now let's just pretend the internal radio communication components are perfectly modular (in terms of functionality) and can be removed and put back as required.

They systematically begin removing various components and noting which uncanny features of these mystrious devices cease to function. One board removed and they no longer get certain band. Another board removed and the box doesn't talk back (think CB). They meticulously map out all these component to function mappings. The results are indisputable: These boxes are some sort of 'thinking machines'. The 'brains' of the machanisms is isolated to the radio elements of the devices. The 'proof' of this is that the boxes cease to speak or respond to communication when these elements are removed.

> consciousness can be damaged when it's physical container is damaged

Just like those radios.

[hnfong]

Interesting.

I don't think the GP's objection is fatal either (for reasons mentioned in another reply), but let me try to poke holes in your argument.

If I understand your analogy correctly, you're saying the brain here acts as an intermediary between the real consciousness and the physical world, and not really the underlying thing that generates consciousness.

But this seems to contradict actual experience -- if somebody's head is hit very hard, they kind of get knocked dizzy for a moment. Their consciousness halts, until their brain recovers. If your analogy truly holds, then subjectively it should feel more like disconnecting from World of Warcraft. "The real consciousness" fiddles their fingers idly while waiting for reconnection, and once they reconnect they'd have a recollection (on the non-physical, consciousness side) of what happened during the physical blackout.

[yubblegum]

I don't think the insistence on the requirement of 'hard disconnect' is reasonable. Per the brain as transceiver analogy, you are jiggling a part and may get 'static' while you are doing it. Stop the jiggling and static stops. Jiggle too hard and the part disconnects from its socket (knock them out /g) and you'll have the desired disconnect from the "World of Warcraft".

p.s. Realized I didn't address your "subjectively". This is true, since the radio analogy was to address the analog of neuroscientists examining people with damaged brains. You want to know what the 'radio' feels :)

So this is in fact an interesting aspect you bring in. The answer to this is: this seems to conflate 'ego' and 'self'. This is a different problem: Is the self the same as the ego? My own view on this is that is the ego is not the true self.

[hnfong]

I must admit I've never been hit so hard that I am 100% knocked out, so I can't really speak as to the subjective experience of being knocked out (from the non-physical consciousness perspective, not the brain)... but surely it isn't like disconnecting from World of Warcraft?

That said, if the injury is serious enough I suppose it might trigger some Near Death Experience where people have reported seeing things purportedly on the other side.

So I guess that answers my original concern.

(I think you might have confused my question though, or perhaps I've confused you. No worries, my questions are answered anyway.)

[squidbeak]

This is a facile thought experiment, and I'm surprised it's weakness hasn't already occurred to you.

But as it hasn't, let's change your island to an island of supremely skilled butchers. Your islanders are apparently capable of reassembling the mystery radios to restore function, so let's allow my island's butchers the skill of dismembering flesh atomically - and reassembling it exactly. Perhaps via quantum knives and very strong prescription lenses.

Their own religion has long prohibited them from peering into their tribe's flesh - and their tribe is all there is on that remotest of islands. But the day a missionary washes up on shore they see an opportunity. They can finally take a proper look. They begin with his head - by far the most interesting part of him, with the delighted and friendly if slightly smug smile and neverending chatter.

Once dismantled and laid out in trillions of tiny pieces in a large hall - a bit like a crashed plane - they decide to reassemble his head in different configurations - to test how the behaviour would change with each layout. There's an unusual fruit on the island which allows them almost superhuman focus and speed - so that billions of reconfigurations can be completed over an afternoon.

BUT WHAT DO YOU KNOW...? Every single reconfiguration results in a totally inert missionary! No more drunk on the milk of paradise look, and no more "Hallelujah!"s. Just a lump of meat. Perplexed - they decide there must have been something truly unique about the missionary's head's original layout and composition - so reassemble him in the way they found him. But when they have done this - calamity! - he doesn't come on any more. They check their work 18 times - but not a single atom is dislocated. And so the wise islanders come to the only conclusion possible, and hurry to note it in their scientific literature:

"Radios aren't animals. And anyone pretending otherwise is a ginormous silly billy."

[yubblegum]

> "Radios aren't animals. And anyone pretending otherwise is a ginormous silly billy."

The results presented to the scientific community of the island was that the "mechanisms" are "thinking machines". They clearly did not think the boxes to be 'living creatures'.

[squidbeak]

Quite. But for the purposes of his story, their narrator is applying them as an analogue to processes in living creatures.

[teodosin]

Is it consciousness that gets damaged, or just its contents? If you destroy an object, can you say that you've destroyed the space it occupied?
