No, it isn't.
I could write you a program say 20 lines long that would have one thread that reads pixel values from an image, and another thread that monitors the first and declares "I have seen blue!" at appropriate times. But it is no more experiencing anything than a program that prints "Ouch!" when you hit the space bar. It's just a short set of syntactic operations; there's no room for an alternative perspective or layer here. I don't think there's any magic to consciousness, but there's rather more to it than self-reflective syntax. From an AI and neuroscientific perspective it is a fascinating problem, I really don't understand why some people are determined to handwave it. |

No, it isn't. A program is a set of syntactic operations, by definition. If you wish to call it something else, such as an experience, then that's an alternative layer, or perspective.

No, Pixy, it's not.
That's because you don't even have a theory for blue. Not even in human brains, much less machines. You can study the organic machine all you like, and you might discover the neural correlates of blue, but the NCs of blue are not blue. Let's take a common case... a human being looking up at a clear daytime sky. There is no blue in the wavelength of the light. There is no blue in the retinal activity. There is no blue in the neural activity. Blue cannot be deduced from any of that. Now, because of how our brains are built, under those circumstances most of our brains will perform blue. But of course, we can also alter our brains so that they perform something else entirely, perhaps not even color. And of course our brains can (and do) perform blue without any exposure to light at all. So no, all that organic machinery is not, in itself, blue. Blue happens as a result of it, but neither you nor anyone else, at the present moment, can explain why. And because of that, no one has any idea how to make a machine perform blue. That is simply a hard cold fact. |

But even if we map it, we're still not there.
Knowing all the NCCs (neural correlates of consciousness) still would not explain why those neural states are correlated with various experiences. Everyone actually working in the field accepts this, and understands that we currently have no basis even for a theory of why any given NCC is associated with a given experience, and not a different experience, or no experience at all. The AI crowd on this board have simply adopted a long-disproven definition of consciousness and are using that to assert that they're studying consciousness when in fact they're doing no such thing. And they get to deny that this is what they're doing because they only read about machines (ETA: and non-conscious brain processes) and know next to nothing about the current state of brain science when it comes to consciousness. For them, if you can get the machine to respond differently to various wavelengths of light, then you've given it the experience of color. Which is, of course, self-serving nonsense. |

That first article is pretty good until he lobs this bomb:
"I believe that this notion of emergence is incomprehensible" He has absolutely no basis for that assertion. We've figured out tricky stuff before. There's no reason to simply brush aside the possibility that we will eventually figure out how the brain manages to produce a "point of view". |

I’d say Harris most certainly has some basis for that assertion. I think you are reading his conclusion from a rather narrow perspective. The notion of emergence describes the movement from the condition of non-being to the condition of being. Comprehension of this situation would require an experience of non-being. That’s what comprehension is. Understanding the phenomenon in question. Not merely describing objective conditions…but the fact of the matter. The fact of the matter (hypothetically) is that at point A there is non-being…and at point B there is being. Being…subjective reality…consciousness…is the phenomenon in question. They may be necessarily metaphysical questions…but ‘why there is something as opposed to nothing’ and ‘why there is something that has the ability to recognize itself as something’ are the two most intractable questions currently under consideration. I doubt they are merely questions like any other that will be solved because “we’ve figured out tricky stuff before”. |

Emergent properties are not all that complicated, actually.
I agree that the question "Why is there anything rather than nothing?" is likely unsolvable. But there's no clear reason to believe that continued study of the brain will never produce a workable theory of consciousness. |

We don't have a detailed and specific operational theory mapping human neural activity human consciousness. But we do have a basis for such a theory, and you've been provided with it.

The PM/Dennett philosophy sub-routine
Dumb down the definition of consciousness to basic syntax to eliminate the all too human semantic complexity associated with consciousness. Play dumb to any objections that humans are more interesting than that by asking for evidence. |

Nope. We know that different people experience colours in significantly different ways. You can test this, for example, by asking people with normal vision but different cultural backgrounds to distinguish between colours.

I agree, and I think your summary (and Harris') is very good.
I was just saying we don't even know the NCCs yet. Let alone actually tackling the hard problem. So I am puzzled why some people are so keen to make claims like "We know that it's just the conviction 'I have seen blue'" or "If it runs a reflective subroutine on the routine sensing the colour blue, it is experiencing the colour blue". |

You have me wrong. I intended all my posts to be taken as representative of positions I hold or believe. I don't think I have my heart set on one explanation of consciousness. The true explanation is what it is and the experience is what it is. I would like free will to exists, but I'm not going to defending it purely because of that.
I said earlier on that I found the exprience of consciousness, or more precisely - that there is an experience of consciousness surprising. That's because I don't see how it can be compatible with other things I believe. Many of those beliefs are fairly close to Pixy's. Which are in turn similar to beliefs that people I studied AI with held many years ago. I'm certainly wrong somewhere. I don't feel any need to arbitrarily come to a decision about where that is. |

Does this thread reduce down to:
Person A: My experience of consciousness is that there are aspects that can not be reduced to that which can be objectively observed. Person B: Please provide objective evidence for this phonomena that can not be objectively observed. Does anybody who disagrees with Pixy think something different to this? If that's what people mean, then I don't see the purpose of Pixy's/PersonB's question. |

Which artist accepts that his inner life's highest expression is simply the result of the clunking cogs of a big machine?
Which artist could even bother to proceed with their art if it was what they believed? You better get your conscious machines to believe in some rubbish otherwise they will fail the Turing test for sure. |

There is, of course, no distinction between a 'hard problem' and a 'Hard Problem'. The hard problem of consciousness means exactly what it says. Perhaps it will be solved tomorrow. But I doubt it.
Quote:
Person A should just say something more like "I have subjective experiences". That does not claim that such things cannot be described objectively. And it is still the case that person B is asking for objective evidence of subjective states which is close to what the hard problem of consciousness *is*. |

What ever person A's argument is based on, if somebody more or less explicitly says that they believe the type of consciousness they are talking about is either outside of todays, or any, objective explanation, asking for objective proof is either foolishness or trollery.
For myself, I don't see right now how any objective explanation of the actual experience of being consciousness is possible without some kind of a "step 2: magic happens" hand waving. Right now that seems to be stuff about maps and emergent properties. Equally, I don't see how a reductive/Pixy world view can be false. Incidentally, I agree that it is argument from incredulity. Knowing that doesn't change anything. What is one supposed to do, provide objective evidence that something is beyond objective analysis? Asking for such a thing is foolishness or trollery. |

So-called "Hard Problem Consciousness" is explicitly dualistic, and hence, inherently inconsistent. At best it's meaningless.

When someone has abandoned reason and evidence, trying to help them back to reality is trolling?

Seriously. Think about it. And tell me what there is about subjective experience that isn't answered by that explanation.

This is your misconception. The Hard Problem of Consciousness is just a statement of the problem.
Sure, the Hard Problem leads some people towards Dualism but it is not inherent to the problem at all.
Quote:
![]() Of course the reason I have not given objective evidence of subjective states is that I did not believe this is possible at this time. To me, someone thrashing about is not in itself evidence of a subjective state any more than my hypothetical program printing "Ouch!" on a screen is. For various reasons I assume that the behaviour of other people (and animals) is correlated with subjective states, as it is with my own mind. |
