I will be the controversial one and say that I reject that “consciousness” even exists in the philosophical sense. Of course, things like intelligence, self-awareness, problem-solving capabilities, even emotions exist, but it’s possible to describe all of these things in purely functional terms, which would in turn be computable. When people like about “consciousness not being computable” they are talking about the Chalmerite definition of “consciousness” popular in philosophical circles specifically.

This is really just a rehashing of Kant’s noumena-phenomena distinction, but with different language. The rehashing goes back to the famous “What is it like to be a bat?” paper by Thomas Nagel. Nagel argues that physical reality must be independent of point of view (non-contextual, non-relative, absolute), whereas what we perceive clearly depends upon point of view (contextual). You and I are not seeing the same thing for example, even if we look at the same object we will see different things from our different standpoints.

Nagel thus concludes that what we perceive cannot be reality as it really is, but must be some sort of fabrication by the mammalian brain. It is not equivalent to reality as it is really is (which is said to be non-contextual) but must be something irreducible to the subject. What we perceive, therefore, he calls “subjective,” and since observation, perception and experience are all synonyms, he calls this “subjective experience.”

Chalmers later in his paper “Facing up to the Hard Problem of Consciousness” renames this “subjective experience” to “consciousness.” He points out that if everything we perceive is “subjective” and created by the brain, then true reality must be independent of perception, i.e. no perception could ever reveal it, we can never observe it and it always lies beyond all possible observation. How does this entirely invisible reality which is completely disconnected from everything we experience, in certain arbitrary configurations, “give rise to” what we experience. This “explanatory gap” he calls the “hard problem of consciousness.”

This is just a direct rehashing in different words Kant’s phenomena-noumena distinction, where the “phenomena” is the “appearance of” reality as it exists from different points of view, and the “noumena” is that which exists beyond all possible appearances, the “thing-in-itself” which, as the term implies, suggests it has absolute (non-contextual) properties as it can be meaningfully considered in complete isolation. Velocity, for example, is contextual, so objects don’t meaningfully have velocity in complete isolation; to say objects meaningfully exist in complete isolation is to thus make a claim that they have a non-contextual ontology. This leads to the same kind of “explanatory gap” between the two which was previously called the “mind-body problem.”

The reason I reject Kantianism and its rehashing by the Chalmerites is because Nagel’s premise is entirely wrong. Physical reality is not non-contextual. There is no “thing-in-itself.” Physical reality is deeply contextual. The imagined non-contextual “godlike” perspective whereby everything can be conceived of as things-in-themselves in complete isolation is a fairy tale. In physical reality, the ontology of a thing can only be assigned to discrete events whereby its properties are always associated with a particular context, and, as shown in the famous Wigner’s friend thought experiment, the ontology of a system can change depending upon one’s point of view.

This non-contextual physical reality from Nagel is just a fairy tale, and so his argument in the rest of his paper does not follow that what we observe (synonym for: experience, perceive) is “subjective,” and if Nagel fails to establish “subjective experience,” then Chalmers fails to establish “consciousness” which is just a renaming of this term, and thus Chalmers fails to demonstrate an “explanatory gap” between consciousness and reality because he has failed to establish that “consciousness” is a thing at all.

What’s worse is that if you buy Chalmers’ and Nagel’s bad arguments then you basically end up equating observation as a whole with “consciousness,” and thus you run into the Penrose conclusion that it’s “non-computable.” Of course we cannot compute what we observe, because what we observe is not consciousness, it is just reality. And reality itself is not computable. The way in which reality evolves through time is computable, but reality as a whole just is. It’s not even a meaningful statement to speak of “computing” it, as if existence itself is subject to computation, but Chalmerite delusion tricks people like Penrose to think this reveals something profound about the human mind, when it’s not relevant to the human mind.

That’s more religion than pseudoscience. Pseudoscience tries to pretend to be science and tricks a lot of people into thinking it is legitimate science, whereas religion just makes proclamations and claims it must be wrong if any evidence debunks them. Pseudoscience is a lot more sneaky, and has become more prevalent in academia itself ever since people were infected by the disease of Popperism.

Popperites believe something is “science” as long as it can in principle be falsified, so you invent a theory that could in principle be tested then you have proposed a scientific theory. So pseudoscientists come up with the most ridiculous nonsense ever based on literally nothing and then insist everyone must take it seriously because it could in theory be tested one day, but it is always just out of reach of actually being tested.

Since it is testable and the brain disease of Popperism that has permeated academia leads people to be tricked by this sophistry, sometimes these pseudoscientists can even secure funding to test it, especially if they can get a big name in physics to endorse it. If it’s being tested at some institution somewhere, if there is at least a couple papers published of someone looking into it, it must be genuine science, right?

Meanwhile, while they create this air of legitimacy, a smokescreen around their ideas, they then reach out to a laymen audience through publishing books, doing documentaries on television, or publishing videos to YouTube, talking about woo nuttery like how we’re all trapped inside a giant “cosmic consciousness” and we are all feel each other’s vibrations through quantum entanglement, and that somehow science proves the existence of gods.

As they make immense dough off of the laymen audience they grift off of, if anyone points to the fact that their claims are based on nothing, they just can deflect to the smokescreen they created through academia.

Color is not invented by the brain but is socially constructed. You cannot look inside someone’s brain and find a blob of green, unless idk you let the brain mold for awhile. All you can do is ask the person to think of “green” and then correlate whatever their brain patterns are that respond to that request, but everyone’s brain patterns are different so the only thing that ties them all together is that we’ve all agreed as a society to associate a certain property in reality with “green.”

If you were an alien who had no concept of green and had abducted a single person, if that person is thinking of “green,” you would have no way to know because you have no concept of “green,” you would just see arbitrary patterns in their brain that to you would seem meaningless. Without the ability to reference that back to the social system, you cannot identify anything “green” going on in their brain, or for any colors at all, or, in fact, for any concepts in general.

This was the point of Wittgenstein’s rule-following problem, that ultimately it is impossible to tie any symbol (such as “green”) back to a concrete meaning without referencing a social system. If you were on a deserted island and forgot what “green” meant and started to use it differently, there would be no one to correct you, so that new usage might as well be what “green” meant.

If you try to not change your usage by building up a basket of green items to remind you of what “green” is, there is no basket you could possibly construct that would have no ambiguity. If you put a green apple and a green lettuce in there, and you forget what “green” is so you look at the basket for reference, you might think, for example, that “green” just refers to healthy vegetation. No matter how many items you add to the basket, there will always be some ambiguity, some possible definition that is compatible with all your examples yet not your original intention.

Without a social system to reference for meaning and to correct your mistakes, there is no way to be sure that today you are even using symbols the same way you used them yesterday. Indeed, there would be no reason for someone born and grew up in complete isolation to even develop any symbols at all, because they would just all be fuzzy and meaningless. They would still have a brain and intelligence and be able to interpret the world, but they would not divide it up into rigid categories like “green” or “red” or “dogs” or “cats.” They would think in a way where everything kind of merges together, a mode of thought that is very alien to social creatures and so we cannot actually imagine what it is like.

So a couple of intergalactic hydrogen atoms could exchange a photon across light years and become entangled for the rest of time, casually sharing some quantum of secrets as they coast to infinity.

No “secrets” are being exchanged between these particles.

The point wasn’t that the discussion is stupid, but that believing particles can be in two states at once is stupid. Schrodinger was doing a kind of argument known as a reduction to absurdity in his paper The Present Situation in Quantum Mechanics. He was saying that if you believe a single particle can be in two states at once, it could trivially cause a chain reaction that would put a macroscopic object in two states at once, and that it’s absurd to think a cat can be in two states at once, ergo a particle cannot be in two states at once.

In his later work Science and Humanism, Schrodinger argues that all the confusion around quantum mechanics originates from assuming that if that particles are autonomous objects with their own individual existence. If this were to be the case, then the particle must have properties localizable to itself, such as its position. And if the particle’s position is localized to itself and merely a function of itself, then it would have a position at all times. That means if the particle is detected by a detector at t=0 and a detector at t=1 and no detection is made at t=0.5, the particle should have some position value at t=0.5.

If the particle has properties like position at all times, then the changes in its position must always be continuous as there would be no gaps between t=0 and t=1 where it lacks a position but would have a position at t=0.1, t=0.2, etc. Schrodinger referred to this as the “history” of the particle, saying that whenever a particle shows up on a detector, we always assume it must have come from somewhere, that it used to be somewhere else before arriving at the detector.

However, Schrodinger viewed this as mistake that isn’t actually backed by the empirical evidence. We can only make observations at discrete moments in time, and to assume the particle is doing something in between those observation is by definition to make assumptions about something we cannot, by definition, observe, and so it can never actually be empirically verified.

Indeed, Schrodinger’s concern was more that it could not be verified, but that all the confusion around quantum theory comes precisely from what he called trying to “fill in the gaps” of the particle’s history. When you do so, you run into logical contradictions without introducing absurdities, like nonlocal action, retrocausality, or these days it’s even popular to talk about multiverses. Schrodinger also pointed out how the measurement problem, too, directly stems from trying to fill in the gaps of the particle’s history.

Schrodinger thought it made more sense to just abandon the notion that particles are really autonomous objects with their own individual existence. They only exist at the moment they are interacting with something, and the physical world evolves through a sequence of discrete events and not through continuous transitions of autonomous entities.

He actually used to hate this idea and criticized Heisenberg for it as it was basically Heisenberg’s view as well, saying “I cannot believe that the electron hops about like a flea.” However, in the same book he mentions that he changed his mind precisely because of the measurement problem. He says that he introduced the Schrodinger equation as a way to “fill in the gaps” between these “hops,” but that it actually fails to achieve this because it just shifts the gap between from between “hops” to between measurements as the system would evolve continuously up until measurement then have a sudden transition to a discrete value.

Schrodinger didn’t think it made sense that measurement should be special or play any sort of role in the theory over any other kind of physical interaction. By not trying to fill in the gaps at all, then no physical interaction is treated as special and all are put on an equal playing field, and so you don’t have a problem of measurement.

What a lot of people aren’t taught is that when quantum mechanics was originally formulated, it had no Schrodinger wave equation and it had no wave function, yet it was perfectly capable of making all the same predictions that modern quantum mechanics could make. The original formulation of quantum mechanics by Heisenberg is known as matrix mechanics and it does not have the wave function, it instead really does treat it as if particles just hop from one physical interaction to the next. Heisenberg believed this process was fundamentally random and so at best you could ever hope to make a probabilistic prediction, so he treated the state vector as something epistemic, i.e. the particle doesn’t literally spread out like a wave, it just hops from one interaction to the next and you make your best guess using probability rules.

Again, matrix mechanics can make all the same predictions as standard quantum mechanics, and so the wave function formulation is really just a quirk of a very specific way to mathematically formulate the theory, so assigning it such strong ontological validity is rather dubious as it is not indispensable. Superposition is just a mathematical notation representing the likelihoods of different results when a future interaction occurs, such as with your measuring device. It doesn’t represent the ontological status of the system in that very moment, because the system does not even have its own ontological status. As Schrodinger put it, particles on their own have no “individuality.” Physical systems only have ontological reality when they are participating in a physical interaction.
