It's only a thing if you can define it, but there is no agreed upon definition of what collection of things comprise consciousness. We have all the pieces, and we know we have all the pieces (note: this doesn't mean we don't have a lot more to learn, both can be true). There is little controversy over how it all roughly works together. The only real controversy is semantics: what do we mean when we say "consciousness…

A phenomena can be defined by a pattern, even if it’s not well defined in a technical sense. And a pattern is a thing. Consciousness is an everyday experience that appears to be reliably shared by billions of entities who communicate about it to each other. And have done so for at least millennia. To use a colloquialism: It’s a thing

There are types without values. That the type is itself a value does not mean that it has values itself. False is a type with no values. Consciousness is not a value.

Replace type with concept and value with thing, and we get a rebuttal using the same language. You can also switch the terms, depending on how 'a thing' is interpreted. If you are more familiar with set theory, replace type with proposition, value with element. The critical difference is between reference and referent.

Further if large numbers of people holding something is true for considerable duration is sufficient for something to 'be a thing', we'd also have an argument for 'the consciousness of the human heart' being a thing, which I don't think anyone would argue in good faith these days. There are probably better examples, but note that the duration of time and frequency of experience are parameters with no obvious values indicating at which point the underlying 'thing' should be accepted as undeniably 'a thing'.

The whole point of requiring it to be technically defined is that all this confusion just goes away and it becomes possible to ask more meaningful and less ambiguous questions about it.

That said, I will concede that the argument I have made does not say that consciousness is definitely not 'a thing', just that it is defensible to say that it is not a thing, given that it is held that either it does not represent a proposition, or that the proposition it represents is not true. (note I'm using the term proposition with some handwaving).

I've always thought consciousness is basically just feedback (like with microphones). Sensing yourself sensing yourself etc.

That's self-awareness. But it doesn't explain qualia like the sensation of the color red.

I don't understand the mystery around "qualia". You sense something and it propagates through the system priming other neurons. It's just learned association.

What you are referring to is the soft problem of consciousness, the contents of consciousness. You are probably right that the contents of human consciousness, or qualia, can be approximated by our understanding and technology to a very high degree given enough time. However, OP was referring to the hard problem of consciousness. The hard problem of consciousness is unsolvable IMHO by science, as it is entirely subje…

I think people have confused the matter by splitting into soft/hard. There is only 1 consciousness. Soft is describing how it can be done physically, how to build it, or explain it, and hard is what it is like to experience it from the inside. By creating the hard problem, it really just says "we can't know anything about any internal state". All "internal subject states" are self reported, and a machine can just as…

Sorry, you are part of the 90% confusing the hard and soft problem without understanding what is hard about the hard problem. In fact, merely realizing the hard problem of consciousness is one of the first stages that is reached in modern vipassana meditation.

The hard problem is not stating "we can't know anything about any internal state", it is about the mere subjective existence of the internal state and not about the contents of internal experience or any objective fact about that internal state. I don't know why this is seems often so hard, but in consciousness research and meditators' language (or in my native language at least), most of this seems pretty well-definded.

It has no relation to proving that humans or machines are conscious. It is about no objective fact at all, and thus cannot be investigated using objective methods. That is why it is unsolvable by objective science.

To use a koan-like: It is about this.

I was probably unclear. Meant, "we can't know 'others' internal state". We can examine our own, but all we can do is try to express it in language. Someone else hearing our description can only get a vague idea. And vice versa. Each person has their own individual internal subjective perspective, which can't be communicated with 100% clarity or accuracy. Since we can't examine or measure others internal state, we deem it 'hard' and 'impossible'. Because of course it is hard to express something that can't be communicated.

I would say that this examination of the problem of our internal view of the world, versus the reality of the world, subject versus object, goes back thousands of years.

I've also meditated a long time, and I do understand the hard problem. I just don't think eastern philosophies have the answer either. Eastern philosophies definitely had a jump start on the West with examining the mind, and really it was Buddhism that informed western philosophies from Schopenhauer onward. They helped defining some vocabulary and hierarchies, like outlining Skanda's or parts.

BUT, the typical eastern answer, that it is just 'this" and other 'wooo-wooo' answers are just as far from any explanation to the 'hard' problem as anybody in the west has. Meditation can get you awareness of the hard problem, some insight, but it still isn't an explanation. It just gets you another perspective that is still "Internal". I can meditate forever, but any 'realization' is still internal to me, it isn't providing any answers or explanation.

This comes up a lot right now with AI getting so human like (recent advancements), and I would say that at some point we'll create something that will be indistinguishable from a human, and at that time if the AI speaks convincingly of their realization of 'this is it', we wont have any ability to disprove that they really have had the same 'wooo-wooo' feelings. There is no way to prove anything.

So what I am speculating here, is that at some time in near future, we will be able to correlate soft and hard problems, so we have a map from one to another. And we'll have to realize that our own internal 'experience of reality' is just our neural net in our brain reacting and processing to stimuli, and we'll be able to examine the same things in silicon. And we'll have to accept that we aren't some super mystical beings or that our 'consciousness' is not all that special a development in the universe.

When I try to state this in natural language I come to something like "Conscious states consist of qualities, or contain qualia. And they are unified _in_ consciousness, meaning that our experience is whole. The mathematical structure is this: For any set of experiencing qualities there is a(n additional) state integrating them all into one state."

When I studied philosophy in the 2000s we discussed such kinds of solutions already in a seminar and found them lacking on two grounds.

First: there is no clear notion of non-conscious qualia, and Ockham help us here to keep it so. But if this is true, each of the integrated states already presupposes the whole (because it is already conscious, consciousness is more the medium of qualia), which then cannot come after them to unify them. Unless one wants to assume that a lot of conscious splintered experiences are integrated into a whole later. That would be even more questionable, because who experiences them?

Second: The integrating state needs another integrating state to integrate it into the whole of conscious experience etc. ad inf. Unless it is a state that integrates itself into the whole as well, which would just be a sleigh of hand - because exactly that is the riddle that a mathematical structure must overcome to be about consciousness. The self-reference, the self-presentation of consciousness. Apologies for lacking the proper terminology here.

> Again you don't know what you're talking about. I think that's a bit uncharitable. You're acting like people haven't been grappling with these problems for thousands of years. Searle, for example, makes a pretty good argument why symbol-processing systems will never produce consciousness (you'd have to prove that the Chinese room is conscious, etc.).

Philosophers grapple with the problem the same way Greeks used mythology to grapple with the problem of reality. Thunder is not thrown by some god named Zeus. and the impossibility of a mathematical model describing consciousness cannot be explained away by a Chinese room argument that has tons and tons of qualitative holes in it. If an atom can be described by a mathematical equation that means so can groups of atom…

> But what chatGPT is, is not clear.

I would posit that it is clear. It's simply a whole bunch of toasters put together (that is, a long list of if-then statements). If you're trying to argue that consciousness is merely a bunch of if-then statements, then yes, ChatGPT might be conscious. But then it's going to be much harder to argue that a toaster isn't conscious, which I thought we both agreed with.

> Likely you believe in a soul or something if you don't agree with the logic.

This seems a bit dismissive, and although I myself am a substance dualist (which is generally seen as a metaphysical position), most materialists aren't mechanistic in their interpretation of consciousness.

Nope I'm not. Every aspect of your experience is your nervous system and the sensory organs at work. The "Why is red RED?" thing is a complete joke from a scientific standpoint.

Yes, you are. > Every aspect of your experience is your nervous system and the sensory organs at work There's still a leap from that to the existence of subjective experience.

There is not, though. It's all there is.

It's almost like by insisting that there is a subjective experience (as opposed to what?) you close your eyes to how that experience arises, and prefer instead to implicitly attribute it some magical attributes such that it can never be explained mechanically.

I think you’re confusing consciousness (qualia, the subjective experience of being you) with awareness.

Well, it's not a joke in the sense that it gives adults a good opportunity to explain how things work to children.

By your standards, a "soul" is also a "thing" which science struggles to explain, right?
