Yes, I see all that, but if you can't tell the difference between them (and there is no physical difference between them other than location), what difference does their individual histories make? Are they not indistinguishable and therefore interchangeable? For example, if I'd stolen your coin and the coin I actually gave back to you was your original coin, the 'difference' is just a matter of what you believe about the coin.
I realise that in art, for example, people have been fooled by fakes, but fake art is physically different, and can, in principle, be distinguished from the original. |

Seems to me coins don't have a perspective, and if there's no physical difference between them, I don't see how there could be a difference even if they did have one (unless we're talking about some weird dualist coin 'spirit'!)... but I don't want to derail the thread, so OK.

The point is, it isn't how we normally define identity.
Your reasoning seemed to me to be "If two entities are physically the same, then they are one entity". But we don't do that for any kind of entity, except for consciousness in hypotheticals like this one. (with the caveat that if two entities are the same including extrinsic properties like location, then yeah I'm happy to say they are one and the same) ------------------ The coins are just to illustrate that single point. If you go further into the coins hypothetical, we'll inevitably start thinking about "what if the coins were conscious" and at that point obviously thinking about coins isn't helping us. |

I did read your posts, maybe I just wasn't satisfied with your answers.
![]() To be clear, I agree that the "what if the original isn't killed but tortured for an hour"-scenario is obvious, and scary. However, I'm not so sure this tells us that there is something wrong with using a transporter. Rather I suspect it's telling us that there is something mistaken about our notion of self. Code:
^ a) orig copy b) orig copy c) orig1 orig2 | orig copy orig copy orig1 orig2 | ___orig__copy___ ___orig__copy____ ___orig1__orig2___ | orig orig orig | orig orig orig | orig orig orig Code:
^ d) orig orig | orig orig | ____orig__orig____ | orig | orig | orig And lastly, on the value of life, since you brought it up; I want to be happy and I want other people to be happy because I know what happiness feels like. I don't want to suffer and I don't want other people to suffer because I know what suffering feels like. Going around killing people would definitely cause a lot of suffering. Using a (fool proof) transporter? No one suffers. |

I think this thread has shown that how we normally define a lot of things, like life, death, self, and perhaps, identity, need refining, or redefining, or reconsidering, in the face of abnormal contexts like perfect replication.

Yes, it is. The brain is a processor, that developed through evolution. Natural selection results in it being programmed to create and protect a sense of there being someone that is experiencing.
As Susan Blackmore amongst others has pointed out, many of our finest scientific minds, even one with a Nobel prize, find it virtually impossible to write papers on consciousness without slipping into dualism. Not because they're stupid. Intelligence is relatively meaningless here. But because what becomes apparent, when studying at a neuronal level, is so contrary to what the brain believes about itself, it just can't accept it. The brain of the scientist is programmed to create this illusory, persisting self just the same as the brain of everyone else... and it doesn't like the look of it! Strong AI is patently obviously correct. It's a no brainer. But it will be decades before there's a scientific consensus behind it. Not because there's not an overwhelming level of evidence, but because human brains are programmed to resist it. Nick |

Much as many science writers tend to slip into the language of purpose and intent when describing evolutionary traits. Very annoying.

I don't think so; I think there is the philosophical issue of identity which we could discuss even about non-conscious entities. The only difference that consciousness makes here is that it makes the problem have practical significance (someday).

What!? How did it suddenly become the illusion of consciousness?! Illusion of there being an experiencer of consciousness - that's what's being discussed.

There is no sharp boundary. It would depend on what is at stake, on how good the reason is for me to be killed.
Yes, of course! But *I* have to make that distinction, *nature* does not do that for me. It won't pull the plug stopping my subjective experience of self at some arbitrary threshold. Because this subjective persistent self was an illusion from the get-go. |

Well, you insist that we use the word "processing" instead of things like sensation or qualia. This implied to me the typical semantic handwave that is very common when discussing consciousness.
My position is simply that whatever someone wants to call sensations like colour, pain etc, it's a significant unsolved problem in philosophy and neuroscience. So even if it's an "illusion", or even merely the conviction "I have seen blue", exactly how the brain does that is a hugely significant and difficult problem.
Quote:
There are aspects of self-hood, like continuity that definitely are not all they appear. As I've conceded; it may well be the case that continuity from moment to moment *is* an illusion. But there are aspects of consciousness that have a first-person ontology, no question about it. And in fact, you don't even need consciousness for many aspects of the self. For example, if I get some malware on my computer, did that event happen to anything? Yes, it happened to my computer. Now it's true we could describe that same event in terms of individual bits but a reductionist account is not necessarily "better" than a higher-level description and it doesn't "refute" in any sense that alternative description. So I'm not sure what you mean by a blanket "there is no experiencer".

The problem gets a great deal easier when you accept that sensations, colour, pain, or whatever are not happening a priori to anyone. The narrative of "I am experiencing..." comes along post hoc.
But because the ramifications of this perspective are so counter-intuitive for a human brain, with its evolutionary history, only relatively few philosophers or scientists can actually grasp this. The high intelligence of the researchers is often counter-productive here. Frequently intelligence translates to "having a large number of thoughts." This is not helpful if you're trying to understand for yourself how the "mental self", the "experiencer" is actually being constructed by the brain. The more the brain focusses on thinking, the harder it is to accept that thinking is not actually happening to anyone! This is the real "hard problem" of consciousness research - the fact that the brains of the researchers have been conditioned through aeons of natural selection to defend against the obvious conclusions of their researches! When this is grasped then the mystery of how the brain creates the colour blue or the feeling of pain lessens. This is because it now has to be accepted that the mind is what the brain does. For some people this is considered a cop-out, a viewpoint I sympathize with. But then the reality IME is that most of these people have yet to grasp the issues with self even, so for me this is where they need to go. Then we can look at how. And then we can get into the really BIG mysteries! But you have to get to first base first. You have to understand the transporter and be either happy to travel or accept the irrationality of refusal. If you haven't even got to that point yet, well, I don't know what you can do but keep looking.

Yes, and only you and the people who hold the same position as you, can see through this illusion! Hundreds of neuroscientists and philosophers might work in their fields for decades each and come to a different conclusion, but that just shows how strong the delusion is...

Well, if you look at Chalmers whole qualia thing... It's like he couldn't accept that a bunch of neurons and glia could create the brilliance of the blue sky "he" was experiencing.
I find this perspective pretty egocentric. It's like... The ventral stream has developed over hundreds of millions of years of natural selection. Of course bright colours are highly favoured. It's not rocket science. But if you believe there's someone in the brain experiencing, or some place of observation in there somewhere, some pontifical neuron, whatever, then for sure its harder to accept that the brain can create that blue. Now, if you pull back, and take the idea of an experiencer out of there (which anyway only began to show up likely less than one million years ago) then the brain is just a processing machine. It's developed over aeons of natural selection. From the tiniest chink of light, barely perceptible, is it really so hard to believe that after 100 odd million years of evolution we have bright blue? I don't find it hard at all. But then of course you have to let go of the experiencer. :......... Things are changing slowly. I was on transporter threads 3 or 4 years ago on the jref. It was much tougher then! There's been a sea change in perception IMO. Give it a year or two, Mijin, and you'll travel. And qualia will disappear like fluffy clouds disolving in a clear blue sky.

Well I guess I'm not quite finished here after all.
1. You can't concede that we have the sensation of colour and at the same time say that qualia are nonsense. Qualia is just a name for sensations like colour. 2. The vividness or brightness of colours is basically irrelevant here. The mystery is how brains make colours, period, whether they be a bright blue, dull blue or an inky blackness (yes, I know in an art sense black is not considered a colour, but it is nonetheless a sensation generated, somehow, by the brain). So to say "Of course bright colours are highly favoured. It's not rocket science." I don't even know what straw man you're arguing against. 3. I see now why you keep talking to pull everything back to "there is no experiencer"; you believe that it solves (or at least helps explain) various apparent mental phenomena. I'm dubious of that, and particularly in terms of qualia, I don't see how it helps at all. e.g. I don't see why you couldn't have an animal that is not self-aware but feels pain. Is your position that this is impossible? Why? |

There's always the idea that colour qualia are what it's like to have certain coding vectors across the color-opponent neurons in your primary visual pathways - as explained here.
However, I suspect that even a description that permits one to predict and generate novel colour perceptions such as chimeric, hyperbolic, and self-luminous colours, will not be sufficient to satisfy a question that ultimately boils down to 'why anything?' It may help a little though. |

Mijin,
No one is having the experience of colour. No one is having the experience of colour. The colour is there. That's it. Colour is what the brain is doing. What the brain is also doing, in an adjoining network, is creating the narrative "I am experiencing colour." The combined activity of these two networks creates the emergent belief for the brain that it is an "I" and that it is "experiencing colour." But it is not. This is just an evolutionarily-favoured learned behaviour. There is colour. There is a narrative. From this activity so-called "experience" emerges.
Quote:
It is not that there exists some self and for this self the brain is creating these colours, and then this self is saying "but how can this brain possibly create these colours?" That is reality upside down. It is that colour is what the brain does. Can you also follow this? I'm genuinely interested. Because I can follow your line of thought easily. And I can also see the other side, the materialist viewpoint. Can you?

I wasn't aware “access consciousness” had fallen out of favor (or even what it was, exactly). Nevertheless, on the analogy with running, where not every muscle twitch constitutes running, I think a useful distinction can be made between neuron firings which constitute consciousness and those that don't.
Anyway, as far as what's relevant for this thread, I'm only concerned with "consciousness" as physical activity (a subset of the physical activity we call "mind", which is a subset of the physical activity we call "body"). As a physical activity then, it is bound by physical law and properties, including location (good luck deriving physics without location -- x = location, Δx = change in location, Δx/Δt = velocity, etc. -- as a relevant physical property). Therefore location, differences in the location property, can't be ignored when describing consciousness (according to physicalism, that is; it can be ignored if we assert consciousness is not physical [implying some sort of dualism]).

You can bold it all you like but it's completely irrelevant to what I was just talking about.
I said that qualia is simply a label for experiences like colour. And I pointed out that you have conceded that such experiences exist. So you cannot then say that qualia are nonsense. If you want to say the best explanation for qualia is that they are merely the conviction "I have seen blue" then I would disagree with you but at least that position is internally consistent.

I'm fine if you say qualia is simply another word for experience. I avoid the term because of the associations that come from the hard problem debate.

I'm OK with this hypothesis. I see no reason to believe it is true at this time.
Quote:
You can believe it if you want but please just bring facts and reasoned argument to the debate. Secondly the transport position is not necessarily the materialist position; indeed many argue the exact opposite to you and that a materialist must conclude no transport is possible. So what's your basis for coming to the conclusion you have? Finally, I'm not actually a materialist. I've put my reasons why in a spoiler box as it's off-topic. |

I was having a look at Derek Parfit because I was interested in this "acid test". I thought it was a bit droll that he's presently an Emeritus Senior Research Fellow at All Souls College, Oxford. All Souls!
Then I looked up Susan Blackmore and found it here. "Imagine you want to go to the beautiful city of Capetown for a holiday. You are offered a simple, free, almost instantaneous, and 100 per cent safe, way of getting there and back. All you have to do is step inside the box, press the button, and ..... The box is, of course, Parfit’s teletransporter. In making the journey every cell of your body and brain will be scanned and destroyed, and then replicated exactly as they were before, but in Capetown. Would you press the button?" No, I wouldn't press the button. And I do consider myself a materialist. I think of myself as a machine made of matter which is in turn made of energy. So in the end I consider myself to be a complicated pattern as it were. But it's this particular pattern, this self, right here, and I don't want it destroyed thanks. Like edx said, I might press some other button to create a copy without being destroyed myself, and I have no awareness of that other copy. I don't find myself looking out of his eyes. This consciousness I enjoy is an illusion, it doesn't really exist, but it's the only thing that's real to me, to itself. |

So you assert. But as I said, many people disagree with you. e.g. Fellow materialist and indeed reductionist Mark Johnston (currently a philosophy professor at Princeton) is of the opinion that "Even if the lower-level facts [that make up identity] do not in themselves matter, the higher-level fact may matter. If it does, the lower-level facts will have derived significance. They will matter, not in themselves, but because they constitute the higher level fact".
So you cannot just say "If you're a materialist, you will be happy to step into the transporter". Nor can you assert that Strong AI is true. There needs to be some argument why this is the case. (or rather; you can assert whatever you like, but it won't convince anyone) And at this point it occurs to me your position is not really the transport position. You threw me by saying it would be irrational not to step into the transporter. Because, in reality, your position is that it makes no difference what I do: the destination entity is not me and the source entity is not me because there is no me. I shouldn't really care about the transporter or indeed care about anything.

Nick: I just looked up Dualism. It says dualism is the assumption that mental phenomena are, in some respects, non-physical, or that the mind and body are not identical. Later on it says Dualism is closely associated with the philosophy of René Descartes (1641), which holds that the mind is a nonphysical substance. It's talking about souls. Whoa! I'm not a duallist. I consider myself to be a mere machine. But I'm this machine, not some other identical copy of it.
Mijin: I have a degree in computer science. I think that I you could build a computer that was as complex as the human brain, and if you could teach/educate it adequately, it would not only act as if it was conscious, but it would actually be conscious. |

Ditto. I also have a postgrad in neuroscience.
Quote:
The simulation of a storm won't get you wet, and the simulation of a brain is not necessary conscious unless you assume the brain is essentially a computer program and strong AI is true. And note the distinction between machine and computer; the brain is certainly a kind of machine, I don't think it's necessarily a computer. |

Yes, this is the problem - it is subjectively real to the extent that it feels real, and in a very real sense (!) that's as real as anything gets. We can rationalise the cognitive dissonance created by external illusions of a conjuror or magician with only minor discomfort, but internal self-referential illusions are far more difficult to manage - phantom limb syndrome, alien hand syndrome, etc., are problems on the boundaries of self, but the core subjective sense of self is a tougher nut to crack.

And I would 100% agree with him. I'm not ascribing any value judgments to the reality of self laid bare by the Transporter.
Others might say "oh, its all pointless then", or try and change how they are to accommodate the reality that the "experiencer" is illusory under materialism. But this is their trip, not me.

I see it more as the destination entity is as much you as the source entity was. A subtle distinction, perhaps, but I think it's an important one.

It's more than just a value judgement. Maybe I didn't pick the best quote of his but anyway, Johnston is on record as disagreeing with parfit, and he's a respected philosopher who considers himself a materialist.
So you can't say a true

I would find that a misleading way of putting it to say the least. If your position is anything like Nick227's, the statement "The destination entity is me" is entirely false, just like "X is me" for any X.
It's equivalent to saying "This dessert is just as delicious, just as wonderful as the main course" when what you mean is that both were equally disgusting and now you're going to be violently ill. |

Well it is. In both cases it's someone taking two entirely false statements and saying they are as just as true as one another. = misleading
As for me trying to associate negative emotions, I was talking about bad pudding for crying out loud. It was just a light-hearted simile. Next time I'll just use greek letters or whatever... |

Hi Farsight,
In your previous post you said "I might press some other button to create a copy without being destroyed myself, and I have no awareness of that other copy. I don't find myself looking out of his eyes." You seem to me to be clearly indicating that you believe that there is some separate entity that is looking out from your eyes, one that cannot be recreated in the transfer. And that, sir, is dualism. Am I wrong? Nick |
