> What exactly has it yielded? All of the physics and the sciences downstream of it came out of ancient Greek idea of materialism, the idea that things happen not because of wishes of sapient entities like gods or spirits, but because of matter mindlessly following some simple rules. There was a time when the idea that sun is just a fireball and not some thinking being was as hard to accept, as now is the idea that c…

You seem to have constructed a strawman out of your very own interpretation of idealism. Idealism doesn't condemn the study of nature (i.e. science). It merely says that nature is "dreamt" and that consciousness is the primordial stuff and of a different category. Scientists generally have no problem with this, since they can go on studying observable nature as the purview of science, as it's intended. The problem be…

Could you please help me to find a strongman interpretation of idealism?

The question i am primarily interested in, is: "whether there exists a Turing machine, output of which is indistinguishable from behavior of a human".

This is a purely abstract, mathematical question and should be in the purview of science. As far as i understand the answer to this question given by Idealism is that 1. it is not possible, and 2. when it is done it will still be impossible because despite behaving 100% the same as a human it will be something entirely different (a philosophical zombie), because 1 is true by definition.

Perhaps the confusion arises because we are just talking about different things? And you are not interested in either behavior of this kind of Turing machine, or in detailed description of physics of matter in the brain?

> Quantum nonlocality was demonstrated experimentally and people won the Nobel prize for it

There are still many interpretations possible, e.g. https://en.wikipedia.org/wiki/ER_%3D_EPR or the interpretation proposed by Wolfram Physics project (which i rather like), which keeps local realism, but locality is not on R3 but on a graph.

And the reason that it is overrated, is because it has to feel special for the bearers because it makes them prioritise their survival. Consciousness is largely a way to have a reward function for set of behaviours that keep you alive through reason. It appears at a level where reasoning is intelligent enough that you need a more complex reward function.

This seems like the secular version of "the devil made me do it". We can't be accountable for any of our actions because we are all just molecular machines playing out their predetermined outcome.

We are molecular machines and although the outcome is predetermined, the only way to find out the outcome, is for the machine itself to follow through its course. So this is exactly opposite of "devil made me do it" because you do something not because of external force or because of random chance but because of initial state of the machine which makes you who you are.

Earlier today, I got around to viewing the video you linked to in your first reply. As I have been looking into this issue for several years, its trajectory is familiar: start from a re-statement of Frank Jackson's 'knowledge argument' from "Epiphenomenal Qualia", assume that this shows consciousness to be inexplicable as a physical process, jump to the conclusion that consciousness is the fundamental reality on whic…

What you perceive as a "huge leap" is not so much the promotion of consciousness as fundamental, but rather the demotion of matter from that same stance. The former is simply a byproduct of the latter. That in the process it seems to interlock so well with findings in various fields of study should admittedly be considered for now as just a happy accident. But we've abided by the law of parsimony to orient our inquir…

We should start with the question I posed, as this is the crux of the issue here, and without it, everything else here is moot. I will endeavor to set it out as clearly as I can.

As you put great weight on the 'hard problem' being an insurmountable one for (and only for) materialism, I am sure you are well aware of the seminal importance, for that premise, of what has become known as the 'Knowledge Argument' from Frank Jackson's paper "Epiphenomenal Qualia", and in particular, a thought experiment from that paper which goes by several names (such as 'Mary the Neuroscientist'), and which was called, by the philosopher Philip Goff, "the greatest argument against materialism."

This argument has several antecedents, including C. D. Broad's argument that chemistry cannot tell us what ammonia smells like, and, as I mentioned in my previous post, Russells aphorism "it is obvious that a man who can see knows things that a blind man cannot know; but a blind man can know the whole of physics." All these arguments are doing essentially the same thing: pumping the intuition that knowing what it is like to see colors (or have any other phenomenal experience) is not something that could ever be learned by studying the physical sciences (I say they pump the intuition because it is not actually an established fact that the premise is correct, but to be clear, I think it is, at least for human consciousness.)

There is a certain amount of indirection at work here, in specifying only the physical sciences. We get an equally valid question by substituting other academic disciplines for the physical sciences, and in particular, of course, any philosophy of mind: they do not get a pass on this by being anti-materialist, and certainly any philosophy - such as idealism - which is premised first and foremost on the reality and significance of the hard problem, will have to confront this question (among many others) before it can be regarded as the solution to this problem and as providing an explanation of consciousness.

Your reply is apparently that in this respect, idealism is no different than materialism - it will not enable Russell's blind man to know what it is like to see - from which it follows that the knowledge argument cannot be used by idealists against materialism. I am interested in learning, then, what you - and, by extension, idealists - regard as convincing arguments for there being a hard problem for materialism, specifically.

So when a person commits a crime, they can just say: "the initial state of my molecular machine made me do it!" ...?

To me that is exactly the same as saying "the devil made me do it!"

i.e. both things are euphemisms for "I'm not accountable for my actions"; "I'm not at fault"; "It was beyond my control", etc.

And if you truly believe there is no such thing as free will and that everything is predetermined, then you'd have to agree. Hitler can't be held accountable for his choices; his actions were all predetermined and his fate was sealed at the big bang; he just got an unlucky "initial state".

Since you are exactly the molecular machine, nothing more and nothing less, saying "the initial state of my molecular machine made me do it" is same as saying "the initial state of my self made me do it". So it does not mean that you should not be accountable, on the contrary it means that the action was caused by your essence, what makes you you, and not some outside entity or random chance.

As for the free will, it means that the behavior of a molecular machine depends on machine itself, not on far away stars or a random number generator. One can't say that he got unlucky initial state, because he _is_ that unlucky state. Any change of the state would create someone entirely different. Moreover Stephen Wolfram's computational irreducibility principle implies that despite all the information being contained in initial state, only way to extract predictions from that state is to run the molecular machine and observe its behavior.

> I say they pump the intuition because it is not actually an established fact that the premise is correct, but to be clear, I think it is, at least for human consciousness.

I don't see what's being pumped. As we know from the incompleteness theorem, some truths cannot be proven. The fact of our awareness is another that's often doubted by the same people that doubt the divide separating qualia and conceptual knowing. Has their difficulty to grasp at these intuitions somehow become the burden of those who access them as self-evident?

The hard problem is a linchpin. For those who get it, materialism starts to unravel. Those who don't, think those who do are making stuff up, but they also can't give a single example to counter the argument, nor can they conceive for themselves an entirely novel experience purely out of thought. They can't imagine a new color, think a new taste, conceive of a new sense.

> Your reply is apparently that in this respect, idealism is no different than materialism - it will not enable Russell's blind man to know what it is like to see - from which it follows that the knowledge argument cannot be used by idealists against materialism.

As I said, idealism is only a philosophy. It's mostly a process of elimination resting on conjectures such as the hard problem. As possibilities are removed, remaining candidates hint at the likeliest direction, but it's indeed not a final realization. There are some metaphysical speculations resting atop the foundations that reality is mind first. But I'm personally much less invested in speculations. I find the challenge of pulling our cultural head out of the sand of implausibility more of a concern.

Depending how curious (and open-minded) you are about "knowledge" that get the "blind man to know what it is like to see", I'd suggest to look into practices that have this as their main goal. They're about engaging consciousness directly with immediate experience (the senses) and existential curiosity (I am aware that I am, but what am I?) to cultivate the seed of an eventual realization. They're known under the umbrella term "nonduality". As an introduction, I suggest this selection of texts spanning multiple nondual traditions aggregated and read by a Buddhist nun https://www.youtube.com/@SamaneriJayasara.

"Useful" were the things that have allowed us to create new technologies: from internet to medicine to rockets. Belief in idealism not only did not produce anything, it did not even make any measurable impact. Parts of the work of Aristotle that were based on idealism are the parts that have been discarded as hindering understanding of physics or plain wrong.

> medicine Sciences that directly concern human flourishing (medicine, psychology, sociology, economy) are either largely stuck in the middle ages (we can barely make things work reliably, and when they occasionally do we are not quite sure why), or in fact invoke materialism-inconsistent ideas to various degrees (e.g., stress being recognised as a cause or contributing factor of numerous diseases). > Belief in ideal…

Why is stress contributing to diseases materialism-inconsistent? In all cases it has a physical mechanism through which the disease is caused.

> Idealism, materialism, dualism, etc. concern theory of mind

Idealism/dualism used to be about other things too. Stepping away from them allowed us to find physics. Now it is concerned with theory of mind only because the other things are explained by physics.

> believed in Aristotle’s takes, too—by being Christian.

I was talking about the actually measurable things he was saying about physics, his takes on soul being successful is irrelevant, since we still do not have any experiment proving that soul exists.

> “does consciousness arise from atoms?”

Science is concerned with the question "whether there exists a Turing machine, output of which is indistinguishable from behavior of a human". This is what most scientists and materialists mean when talking about conciousness.

The other questions are specifically crafted in a way to not have answers, so that idealism/dualism etc. can pretend that they do something useful, while not doing anything.

What is this obsession with making computers human-like? We can put those machine to better uses than forgetting, having biases, making subtle or gross mistakes (hello, ChatGPT) like we do. The AI that some apparently consider top-notch today is only good at powering NPCs in video games. The more serious the use-case, the more harmful it becomes. Moreover, achieving artificial consciousness is only good at fueling en…

We need smarter automation for Star Trek communism utopia to be feasible. Having biases or making subtle mistakes is not really desirable, it's just that we haven't figured out how to have something that can reason without those things.

We need a stronger focus on ethics and being decent to each other.

Be careful for what you wish for. There’s no guarantee immortality doesn’t result in eternal suffering.

Humans generally don’t like eternal suffering, and will fight against it. That’s a reason to think it won’t happen.

I don't like being crushed by rocks but I can fight against it all I want, a rock that's heavier than me will crush me.

But like the brain, language is Turing-complete. Any information Mary's brain can figure out can also be described in language. If the brain could deduce something that couldn't be described with math and language, it would be doing something outside of our current understanding of physics. You could respond that even though computability theory tell us it's possible to describe in language, the description would be…

Oh! That's the argument, "it feels weird". Yes, it may do. I wonder what that feeling means. All this stuff about "Mary" doesn't clarify the source of the feeling. Often a weird feeling points to a misconception. I think language could technically fully describe the experience, but it would be an unimaginable language, and that's why the idea feels weird: it's too difficult to imagine. Also as you say a pre-verbal ch…

Oh! That's the argument. You "reckon" a lot of things about perception here. [Apologies if I misread your tone]

"feels weird" means "seems unlikely" in this context. At the end of the day, that's the most anyone can say on either side of the argument. You can't demonstrate perception works the way you think it works. You're relying on your intuition.

There are some things we can state definitively though.

> I think language could technically fully describe the experience, but it would be an unimaginable language

If it can't be described in normal English, then the brain is doing something beyond what a Turing machine can do. That means it's doing something beyond our current understanding of physics and quantum mechanics. I would call that non-physicalist. You have to choose: either perception can be fully described in English, or the brain is doing something non-physical. Neither option is intuitive, but that's the consequence of the Church-Turing thesis we must live with.
