The term “consciousness” does not meet the scientific criteria

English Русский Lietuvių


For thousands of years people have believed that only humans have “consciousness” and that robots cannot have “consciousness”.
As evidence they claimed that robots will never be able to create art and solve scientific problems, because “consciousness” is absolutely needed for these tasks.
Approximately in year 2017 the first successful AI bots appeared which were based on networks of massively parallel artificial neurons, which mimic the architecture of the human brain.
As it turned out, these AI bots are capable to create art and solve scientific problems.
AI bots without “consciousness” can create art and solve scientific problems better than majority of humans who supposedly have “consciousness”.
Experimental results have shown that “consciousness” is not needed for art creation and for solving problems.

Geoffrey Hinton has earned the title “the Godfather of AI” and he has won Nobel Prize in Physics 2024 for “for foundational discoveries and inventions that enable machine learning with artificial neural networks”.
Geoffrey Hinton said that “consciousness” is useless obsolete term and people will stop using it (the transcript of interview is below).

Hinton: There’s two issues here. There’s a sort of empirical one and a philosophical one. I don’t think there’s anything in principle that stops machines from being conscious. I’ll give you a little demonstration of that before we carry on. Suppose I take your brain and I take one brain cell in your brain and I replace it by — this a bit black mirror-like — by a little piece of nanotechnology that’s just the same size that behaves in exactly the same way when it gets pings from other neurons. It sends out pings just as the brain cell would have. So the other neurons don’t know anything’s changed. Okay. I’ve just replaced one of your brain cells with this little piece of nanotechnology. Would you still be conscious?
Steven: Yeah.
Hinton: Now you can see where this argument is going.
Steven: Yeah. So if you replaced all of them…
Hinton: I replace them all, at what point do you stop being conscious?
Steven: Well, people think of consciousness as this ethereal thing that exists maybe beyond the brain cells.
Hilton: Yeah. Well, people have a lot of crazy ideas. People don’t know what consciousness is and they often don’t know what they mean by it. And then they fall back on saying, well, I know it cause I’ve got it and I can see that I’ve got it and they fall back on this theater model of the mind which I think is nonsense.
Steven: What do you think of consciousness as if you had to try and define it? Is it because I think of it as just like the awareness of myself? I don’t know.
Hinton: I think it’s a term we’ll stop using. Suppose you want to understand how a car works. Well, you know, some cars have a lot of oomph and other cars have a lot less oomph. Like an Aston Martin’s got lots of oomph. And a little Toyota Corolla doesn’t have much oomph. But oomph isn’t a very good concept for understanding cars. If you want to understand cars, you need to understand electric engines or petrol engines and how they work. And it gives rise to oomph, but oomph isn’t a very useful explanatory concept. It’s the essence of a car. It’s the essence of an Aston Martin, but it doesn’t explain much. I think consciousness is like that. And I think we’ll stop using that term, but I don’t think there’s any reason why a machine shouldn’t have it. If your view of consciousness is that it intrinsically involves self-awareness, then the machine’s got to have self-awareness. He’s got to have cognition about its own cognition and stuff. But I’m a materialist through and through. And I don’t think there’s any reason why a machine shouldn’t have consciousness.

He pioneered AI, now he’s warning the world. Godfather of AI Geoffrey Hinton breaks his silence on the deadly dangers of AI no one is prepared for. Geoffrey Hinton is a leading computer scientist and cognitive psychologist, widely recognised as the ‘Godfather of AI’ for his pioneering work on neural networks and deep learning. He received the 2018 Turing Award, often called the Nobel Prize of computing. In 2023, he left Google to warn people about the rising dangers of AI.


Since ancient times, people have believed that living organisms differ from non-living organisms in that they have a special supernatural “vital force” (Latin: vis vitalis).
Based on this theory of vitalism, it was claimed that organic substances cannot be artificially synthesized in the laboratory, because the synthesis of organic substances requires “vital force”, and therefore organic substances can only be synthesized in a living organism.
And indeed, for a very long time, no one was able to synthesize organic substances in the laboratory.
However, in 1828, the German chemist Friedrich Wöhler finally succeeded in synthesizing urea (also called carbamide or diamide of carbonic acid) in the laboratory.
In 1828, the myth that the synthesis of organic substances is impossible without a supernatural “vital force” was destroyed.

The claim about the existence of “consciousness” is just another form of the theory of vitalism, which states that living organisms differ from non-living ones in that they have a special supernatural “vital power” (Latin: vis vitalis).

https://en.wikipedia.org/wiki/Vitalism
Vitalism is a belief that starts from the premise that "living organisms are fundamentally different from non-living entities because they contain some non-physical element or are governed by different principles than are inanimate things." Where vitalism explicitly invokes a vital principle, that element is often referred to as the "vital spark", "energy", "élan vital" (coined by vitalist Henri Bergson), "vital force", or "vis vitalis", which some equate with the soul. In the 18th and 19th centuries, vitalism was discussed among biologists, between those who felt that the known mechanics of physics would eventually explain the difference between life and non-life and vitalists who argued that the processes of life could not be reduced to a mechanistic process. Vitalist biologists such as Johannes Reinke proposed testable hypotheses meant to show inadequacies with mechanistic explanations, but their experiments failed to provide support for vitalism. Biologists now consider vitalism in this sense to have been refuted by empirical evidence, and hence regard it either as a superseded scientific theory, or, since the mid-20th century, as a pseudoscience.
Vitalism has a long history in medical philosophies: many traditional healing practices posited that disease results from some imbalance in vital forces.

https://en.wikipedia.org/wiki/Organic_compound
Organic compound
Some chemical authorities define an organic compound as a chemical compound that contains a carbon–hydrogen or carbon–carbon bond; others consider an organic compound to be any chemical compound that contains carbon.
<...>
Vitalism

Vitalism was a widespread conception that substances found in organic nature are formed from the chemical elements by the action of a "vital force" or "life-force" (vis vitalis) that only living organisms possess.

In the 1810s, Jöns Jacob Berzelius argued that a regulative force must exist within living bodies. Berzelius also contended that compounds could be distinguished by whether they required any organisms in their synthesis (organic compounds) or whether they did not (inorganic compounds). Vitalism taught that formation of these "organic" compounds were fundamentally different from the "inorganic" compounds that could be obtained from the elements by chemical manipulations in laboratories.

Vitalism survived for a short period after the formulation of modern ideas about the atomic theory and chemical elements. It first came under question in 1824, when Friedrich Wöhler synthesized oxalic acid, a compound known to occur only in living organisms, from cyanogen. A further experiment was Wöhler's 1828 synthesis of urea from the inorganic salts potassium cyanate and ammonium sulfate. Urea had long been considered an "organic" compound, as it was known to occur only in the urine of living organisms. Wöhler's experiments were followed by many others, in which increasingly complex "organic" substances were produced from "inorganic" ones without the involvement of any living organism, thus disproving vitalism.

The word “consciousness” is nowhere mentioned in ancient religious scriptures (the Bible, the Quran, the Vedas, etc.).
Religious adepts believe that the scriptures were written by God, and that God wrote down all the knowledge needed by people in the scriptures.
Let’s raise a simple question: if God wrote down all the knowledge needed by people in the scriptures, then why did God never mention “consciousness”? Isn’t that strange?
However, the words “soul” and “spirit” are constantly repeated in ancient religious scriptures.
“Soul” and “spirit” are some kind of “cloudlets” that can separate from the body after a person’s death and:
1) (in Abrahamic religions) go to heaven or hell,
or
2) (in Eastern religions) reincarnate into another body.

When atheism began to spread, atheists rejected the dogma of the existence of “soul” and “spirit”.
But atheists, just like theists, wanted to feel special and miraculous because they both suffered from the same disease of anthropocentrism.
Therefore, atheists simply stole the concept of “soul” and renamed “soul” into “consciousness”, slightly modifying its properties to fit atheistic dogmas.
When atheists claim that they have “consciousness”, this claim is no different from the claim of religious adepts who claim that they have a “soul”.
Both atheists and theists cannot provide a single piece of evidence for their claims.

The claim about the existence of “consciousness” is just another form of anthropomorphism, which claims that man has a supernatural property of “consciousness”.

https://en.wikipedia.org/wiki/Anthropocentrism
Anthropocentrism (from Ancient Greek ἄνθρωπος (ánthrōpos) 'human' and κέντρον (kéntron) 'center') is the belief that human beings are the central or most important entity on the planet.
Wikipedia

https://en.wikipedia.org/wiki/Theism
Theism is broadly defined as the belief in the existence of at least one deity.

In psychology and psychiatry one of the most heavily used terms is “consciousness”.
However let’s raise a simple question: is there any laboratory test which can determine if the concrete object X (man/animal/etc) has consciousness or not? What is the exact list of features which would prove that object X has consciousness? How can we be sure that object X has consciousness or not? As for example, does the amoeba have consciousness or not?
The inconvenient truth is that psychologists/psychiatrists are unable to provide the exact list of features which prove that object X has consciousness, psychologists/psychiatrists are unable to provide any experimental test which would enable to determine if object X has consciousness or not.
If you don’t believe that this is true then here is a little exercise for you personally: where is the evidence that you have consciousness? Please provide at least one evidence that you have consciousness, please provide at least one evidence that you are not the agent without consciousness.
Below is the definition of “agent” from Wikipedia, a good example of “agents” are computer game characters. The agent can interact with environment while being without any consciousness, for interaction with environment the consciousness is not needed. When agent without consciousness interacting with environment is observed by the outside observer, the observer might incorrectly conclude that this agent has consciousness.

https://en.wikipedia.org/wiki/Intelligent_agent
In artificial intelligence, an intelligent agent (IA) is an autonomous entity which observes through sensors and acts upon an environment using actuators (i.e. it is an agent) and directs its activity towards achieving goals (i.e. it is rational). Intelligent agents may also learn or use knowledge to achieve their goals. They may be very simple or very complex: a reflex machine such as a thermostat is an intelligent agent, as is a human being, as is a community of human beings working together towards a goal.

https://en.wikipedia.org/wiki/Philosophical_zombie
A philosophical zombie or p-zombie in the philosophy of mind and perception is a hypothetical being that is indistinguishable from a normal human being except in that it lacks conscious experience, qualia, or sentience. For example, a philosophical zombie could be poked with a sharp object, and not feel any pain sensation, but yet, behave exactly as if it does feel pain (it may say "ouch" and recoil from the stimulus, or say that it is in intense pain).
Wikipedia

People usually think that it is very easy to prove that “I have consciousness” and they provide a whole bunch of “proofs”, however it is very easy to show that all these “proofs” are incorrect and contain multiple errors.
Here are several typical examples of such erroneous “proofs”.

1) “I can feel pain and I respond to pain, as for example when my finger is cut, I remove the finger and this proves that I have consciousness”.
Let’s rephrase this argument in more scientific way: “my reaction to stimulus proves that I have consciousness”. Let’s raise a simple question: is it really so? Does reaction to stimulus really prove that object has consciousness? We will remind how the fire alarm system works. Fire alarm system has sensors for detecting fire, and when these sensors detect fire or smoke – the fire alarm system reacts instantaneously by sprinkling the water, sounding the alarm and/or accomplishing some other actions. I.e. the fire alarm system has a property of being able to respond to stimulus. However does this mean that fire alarm system has consciousness? As we can clearly see from the example with fire alarm system, “reaction to stimulus” is not the proof consciousness.

2) “I can have emotions/feelings and this proves that I have consciousness”.
“The having of emotions/feelings” – is it really the proof of having consciousness? Ok, then what about computer game characters who have emotions/feelings – does this mean that computer game characters have consciousness? As we can clearly see from the example with computer game characters, “having of emotions/feelings” is not the proof consciousness.

https://sims.wikia.com/wiki/Emotion
Emotion is a gameplay feature introduced in The Sims 4. Emotion is a core part of a Sim's simology. Emotion is similar to mood, but is more easily affected by in-game events and social interactions with other Sims. The current emotional state of a Sim is depicted in the lower left corner of the screen while playing. It is also noted that some objects in-game can affect the emotions of some Sims, though the Sim has to already be feeling a particular way in order for an object to affect them emotionally. Sims that are severely emotional can die from their emotions.
There are several ranges of emotions. Sims may reach one stage of an emotion and then progress to a second, more extreme stage of the same emotion. For instance, a Sim that is embarrassed may become very embarrassed. Sims that become extremely emotional may eventually suffer an emotional death.

3) “I can play music and this proves that I have consciousness”.
“The playing of music” – is it really the proof of having consciousness? Ok, then what about people who are unable to play music – are these people without consciousness or not?

4) “I can recognize myself in the mirror and this proves that I have consciousness”.
“Recognizing yourself in the mirror” (a.k.a. mirror self-recognition test) – is it really the proof of having consciousness? Ok, then what about blind people/monkey/etc who are unable to recognize themselves in the mirror – are they without consciousness or not? And what about robots who are able to recognize themselves in the mirror – does this mean that robots have consciousness?

5) “I have goals and I achieve my goals and this proves that I have consciousness”.
Let’s raise a simple question: is it really so? Does “having goals and achieving goals” really prove that object has consciousness? Artificial intelligent agents, like for example computer game characters, have goals and they are achieving goals too. However does this mean that computer game characters have consciousness? As we can clearly see from the example with computer game characters, “having goals and achieving goals” is not the proof consciousness.

6) “Machines/computers/robots can only imitate that they have consciousness, however only humans have true-consciousness.”
Let’s raise a simple question: is it really so? Please provide at least one evidence that you are not the imitation of consciousness, please provide at least one evidence you have true-consciousness.
Your claim “I have true-consciousness” is not the proof of having true-consciousness, because the machine can also claim the same statement that it has true-consciousness.

7) The list of “proofs” might be endless, however in every case it is very easy to show that every “proof” is incorrect.


The truth is that you cannot provide any evidence which would prove that you have consciousness. There is no experimental test which would enable to determine if object X has consciousness or not. In other words, there are no scientific criteria to determine if object X has consciousness or not, which means that the term “consciousness” is totally useless unnecessary ballast for describing and modeling of the behavior of living organism.
People who use term “consciousness” are unable to provide scientific definition of the term “consciousness”, they are unable to provide the list of criteria (the list of features) which would allow to determine if object X has consciousness or not. When a man uses a term/word which he is unable to define then it is quite obvious that such man does not understand himself what he is talking about, it is obvious that his speech is meaningless by definition.
The term “consciousness” is unscientific and has nothing to do with science. The term “consciousness” is pure pseudoscience and has no scientific basis whatsoever – you do not agree with that? Ok, in case if you disagree then please go back to our little exercise – where is the evidence that you have consciousness? Please provide at least one evidence that you have consciousness, please provide at least one evidence that you are not the agent without consciousness. And please do not come back until you have at least one evidence that you have consciousness.
It is important to note however that pseudoscientific term “consciousness” is so deeply rooted into society that this makes almost impossible to avoid it when discussing the functioning of the brain. In Neurocluster Brain Model we use pseudoscientific term “consciousness” only for legacy reasons in order to simplify comprehension of material for the reader – sometimes a little inaccuracy saves a ton of explanation.

https://en.wikipedia.org/wiki/Solipsism
Solipsism (/ˈsɒlᵻpsɪzəm/; from Latin solus, meaning 'alone', and ipse, meaning 'self') is the philosophical idea that only one's own mind is sure to exist. As an epistemological position, solipsism holds that knowledge of anything outside one's own mind is unsure; the external world and other minds cannot be known and might not exist outside the mind. As a metaphysical position, solipsism goes further to the conclusion that the world and other minds do not exist.
<...>
Psychology and psychiatry
<...> Austrian psychiatrist Sigmund Freud stated that other minds are not known, but only inferred to exist. He stated "consciousness makes each of us aware only of his own states of mind; that other people, too, possess a consciousness is an inference which we draw by analogy from their observable utterances and actions, in order to make this behavior of theirs intelligible to us. (It would no doubt be psychologically more correct to put it in this way: that without any special reflection we attribute to everyone else our own constitution and therefore our consciousness as well, and that this identification is a sine qua non of understanding)."
<...>
Philosophical Zombie
The theory of solipsism crosses over with the theory of the philosophical zombie in that all other seemingly conscious beings actually lack true consciousness, instead they only display traits of consciousness to the observer, who is the only conscious being there is.

Falsifiability and testability
Solipsism is not a falsifiable hypothesis as described by Karl Popper or Imre Lakatos: there does not seem to be an imaginable disproof. <...>
Wikipedia

And by the way, if speaking about tests – in computer science there is such thing as “Turing test”.

https://en.wikipedia.org/wiki/Turing_test
The Turing test is a test of a machine's ability to exhibit intelligent behaviour equivalent to, or indistinguishable from, that of a human. In the original illustrative example, a human judge engages in natural language conversations with a human and a machine designed to generate performance indistinguishable from that of a human being. All participants are separated from one another. If the judge cannot reliably tell the machine from the human, the machine is said to have passed the test. The test does not check the ability to give the correct answer to questions; it checks how closely the answer resembles typical human answers. The conversation is limited to a text-only channel such as a computer keyboard and screen so that the result is not dependent on the machine's ability to render words into audio.
The test was introduced by Alan Turing in his 1950 paper "Computing Machinery and Intelligence," which opens with the words: "I propose to consider the question, 'Can machines think?'" Because "thinking" is difficult to define, Turing chooses to "replace the question by another, which is closely related to it and is expressed in relatively unambiguous words." Turing's new question is: "Are there imaginable digital computers which would do well in the imitation game?" This question, Turing believed, is one that can actually be answered. In the remainder of the paper, he argued against all the major objections to the proposition that "machines can think".
In the years since 1950, the test has proven to be both highly influential and widely criticized, and it is an essential concept in the philosophy of artificial intelligence.
Wikipedia

A lot of scientists write a computer programs which try to pass a Turing test, as for example one of the best human chat simulating program is “A.L.I.C.E.”.

https://en.wikipedia.org/wiki/Artificial_Linguistic_Internet_Computer_Entity
A.L.I.C.E. (Artificial Linguistic Internet Computer Entity), also referred to as Alicebot, or simply Alice, is a natural language processing chatterbot — a program that engages in a conversation with a human by applying some heuristical pattern matching rules to the human's input, and in its online form it also relies on a hidden third person. It was inspired by Joseph Weizenbaum's classical ELIZA program. It is one of the strongest programs of its type and has won the Loebner Prize, awarded to accomplished humanoid, talking robots, three times (in 2000, 2001 and 2004). However, the program is unable to pass the Turing test, as even the casual user will often expose its mechanistic aspects in short conversations.
Wikipedia

However let’s raise a simple question: and what about human who fails to pass the Turing test (like for example man with Down's syndrome, an infant, etc)? How we should call a human who fails to pass the Turing test? What word/term we should use for denoting a human who fails to pass the Turing test? If a human fails to pass Turing test then this raises a simple question: “does such human have consciousness or not?”. As we can clearly see from the above examples, the Turing test is unable to determine if the object has consciousness or not. There is not a single scientific tool which would be able to test for the existence of consciousness which means that the term “consciousness” is 100% pseudoscientific term.

https://en.wikipedia.org/wiki/Marvin_Minsky
Marvin Lee Minsky (August 9, 1927 – January 24, 2016) was an American cognitive scientist concerned largely with research of artificial intelligence (AI), co-founder of the Massachusetts Institute of Technology's AI laboratory, and author of several texts concerning AI and philosophy.<...>
He was a critic of the Loebner Prize for conversational robots.
Minsky believed that there is no fundamental difference between humans and machines, and that humans are machines whose "intelligence" emerges from the interplay of the many unintelligent but semi-autonomous agents that comprise the brain. He has stated that "somewhere down the line, some computers will become more intelligent than most people," but that it's very hard to predict how fast progress will be. He has cautioned that an artificial superintelligence designed to solve an innocuous mathematical problem might decide to assume control of Earth's resources to build supercomputers to help achieve its goal, but believed that such negative scenarios are "hard to take seriously" because he was confident AI would go through "a lot of testing" before being deployed.
Wikipedia

https://en.wikipedia.org/wiki/Loebner_Prize
The Loebner Prize is an annual competition in artificial intelligence that awards prizes to the computer programs considered by the judges to be the most human-like. The format of the competition is that of a standard Turing test. In each round, a human judge simultaneously holds textual conversations with a computer program and a human being via computer. Based upon the responses, the judge must decide which is which.
<...>
Criticisms
The prize has long been scorned by experts in the field, for a variety of reasons.
It is regarded by many as a publicity stunt. Marvin Minsky scathingly offered a "prize" to anyone who could stop the competition. The criticism was reinforced when Loebner, resorting to word-play, claimed that Minsky's offering a prize to stop the competition made him a co-sponsor!
Wikipedia

We will explain in more detail the essence of the problem.
Suppose we are sending a probe to a distant planet and the task of the probe is to find out whether there are any objects which have consciousness on this distant planet. In order to solve this problem the onboard computer of the probe needs to contain an algorithm/program, which would test the objects on this distant planet for the presence of the consciousness. We need a detailed list of diagnostic features which would allow to determine whether the object X has consciousness or not.

Wikipedia provides the summary of the endeavors of the pseudoscientists trying to define the term “consciousness”:
1) Question: what is the “consciousness”, how can we detect if object X has consciousness or not? Answer: object X has consciousness ONLY IF it has awareness.

https://en.wikipedia.org/wiki/Consciousness
Consciousness is the quality or state of awareness, or, of being aware of an external object or something within oneself.
Wikipedia

2) Question: what is the “awareness”, how can do we detect if object X has awareness or not? Answer: object X has awareness ONLY IF it has consciousness.

https://en.wikipedia.org/wiki/Awareness
Awareness is the state or ability to perceive, to feel, or to be conscious of events, objects, thoughts, emotions, or sensory patterns. In this level of consciousness, sense data can be confirmed by an observer without necessarily implying understanding.
Wikipedia

In other words: 1) object X has consciousness ONLY IF it has awareness, 2) object X has awareness ONLY IF it has consciousness.
It is obvious that these definitions are circular/recursive definitions. However circular/recursive definitions are meaningless by definition and have nothing to do with science, here is one practical example of such meaningless circular/recursive definition: “To define recursion, we must first define recursion.”

And now let’s raise the question: do such “definitions” of “consciousness” provide any help in making of the algorithm/program which would be able to test the objects for the presence of the consciousness?
Obviously, the answer is “no”.
It is obvious that such “definitions” have nothing to do with science; such blabber is simply the claptrap.

Length: 1 minute

It is important to note that many people have no clue whatsoever about what the word “scientific” means. This is due to the simple reason.
Universities have huge number of faculties which actually have nothing to do with science. As for example, many universities have “faculty of theology” or “faculty of literature”, and so on. And these “faculties” issue diplomas with academic degrees like “master”, “doctor”, “professor”, etc. And what is the activity of such “professors of theology”, what do they do? They study the superstitious writings called “sacred scriptures” and then debate each other about what did Jesus/Muhammad/Krishna/etc said and who is superior over whom – Jesus is superior to Muhammad or vice versa. They can debate whatever they want, however that is not science, this activity does not meet the scientific criteria. And then such people from universities with academic degrees write books, give lectures, talk on TV/radio, etc – they simply flood the society with their claptrap material. When average common people read/listen to this claptrap material they get the false impression that this material is “science” – and this is due simple reason: the authors of that claptrap material have scientific academic degrees. As the result of this, majority of the population are totally incapable to distinguish science from pseudoscience. As the result of this, they are totally incapable to detect circular/recursive definitions and they are totally incapable to understand that circular/recursive definitions are meaningless by definition. That is a huge problem in society.
The article “What is science and what isn't science?” contains more detailed instructions about how to distinguish science from pseudoscience.

Quite often, the same identical terms/words have different meanings in different fields/professions.
As for example, the same identical term/word “syncope” in various fields/professions has the following meanings:

https://en.wikipedia.org/wiki/Syncope
Syncope may refer to one of the following:
   ● Syncope (medicine), also known as fainting
   ● Syncope (phonology), the loss of one or more sounds, particularly an unstressed vowel, from the interior of a word
   ● Syncopation, a musical effect caused by off-beat or otherwise unexpected rhythms
   ● Suspension, in music
   ● Syncope (genus), a genus of microhylidae frogs
Wikipedia

https://en.wikipedia.org/wiki/Syncopation_(dance)
The terms syncopation and syncopated step in dancing are used in two senses:
1. The first definition matches the musical term: stepping on (or otherwise emphasizing) an unstressed beat. For example, ballroom Cha cha is a syncopated dance in this sense, because the basic step "breaks on two." When dancing to the disparate threads contained within the music, hands, torso, and head can independently move in relation to a thread, creating a fluidly syncopated performance of the music.
2. The word "syncopation" is often used by dance teachers to mean improvised or rehearsed execution of step patterns that have more rhythmical nuances than "standard" step patterns. It takes advanced dancing skill to dance syncopations in this sense. Advanced dancing of West Coast Swing and the Lindy Hop makes heavy use of "syncopation" in this sense (although swing music and swing dances feature the "usual" syncopation, i.e., emphasising the even beats).
Wikipedia

The same situation is with the word “consciousness”.
In medicine, the term/word “consciousness” means the “neurological/physiological state/condition”.

The Glasgow Coma Scale (GCS) is a standard means of assessment of the neurological state.
Preoperative Assessment of Adult Patients for Intracranial Surgery

Anesthesiology Research and Practice. Volume 2010 (2010), Article ID 241307, 11 pages

https://en.wikipedia.org/wiki/Glasgow_Coma_Scale
The Glasgow Coma Scale or GCS is a neurological scale that aims to give a reliable, objective way of recording the conscious state of a person for initial as well as subsequent assessment. A patient is assessed against the criteria of the scale, and the resulting points give a patient score between 3 (indicating deep unconsciousness) and either 14 (original scale) or 15 (the more widely used modified or revised scale).
GCS was initially used to assess level of consciousness after head injury, and the scale is now used by first aid, EMS, nurses and doctors as being applicable to all acute medical and trauma patients. In hospitals it is also used in monitoring chronic patients in intensive care.
The scale was published in 1974 by Graham Teasdale and Bryan J. Jennett, professors of neurosurgery at the University of Glasgow's Institute of Neurological Sciences at the city's Southern General Hospital.
GCS is used as part of several ICU scoring systems, including APACHE II, SAPS II, and SOFA, to assess the status of the central nervous system, as it was designed for. The initial indication for use of the GCS was serial assessments of patients with traumatic brain injury and coma for at least 6 hours in the neurosurgical ICU setting, though it is commonly used throughout hospital departments. A similar scale, the Rancho Los Amigos Scale is used to assess the recovery of traumatic brain injury patients.

When medics talk about “consciousness”, they mean the “neurological/physiological state/condition” and such meaning of the term/word matches the scientific criteria.

When religious adepts, who mimic “scientists”, talk about “consciousness”, they mean the object called “consciousness” (“one that is looking at the screen”, “one that hears/sees/feels/etc”) – this meaning of the term/word does not meet the scientific criteria, this is pure pseudoscience.

no satisfactory explanation exists for how an individual is consciously aware of what he perceives.
F.H.C. Crick (1979) recounted his difficulty in attempting to convince an intelligent woman of this problem. She failed to understand why anyone thought there was a problem, feeling that she probably had somewhere inside her head something like a little television set, until he asked, "So who is looking at it?"

Perhaps the most intractable of the old problems of the mind has been the question of the homunculus. Who or what is that? Let me quote Sir Francis Crick, co-discoverer of the double helix, who now is doing research in neurobiology. Writing in Scientific American, he tells of trying to explain to an intelligent woman why it was puzzling that we perceive anything at all: ''She could not see why there was a problem. Finally in despair I asked her how she herself thought she saw the world. She replied that she probably had somewhere in her head something like a little television set. 'So who,' I asked, 'is looking at it?' She now saw the problem immediately.''
How the mind works
By Morton Hunt. The New York Times. January 24, 1982

It is important to note that: 1) the “physiological state” called “consciousness” and 2) the object (“observer”) that has the name “consciousness” – are two different things.
Quite often, the same identical terms/words have different meanings in different fields/professions – the term/word “consciousness” is exactly such a case.

We will remind that religious adepts, who mimic “scientists”, publish articles/books/theses/etc about “consciousness” at industrial scale in which “consciousness” is meant as an object that can be transferred (“transfer of consciousness/mind into another system”, etc.).
Moreover, extremely illiterate religious adepts even claim that “consciousness is located inside quantum microtubules”.

https://en.wikipedia.org/wiki/Mind_uploading
Whole brain emulation (WBE) or mind uploading (sometimes called "mind copying" or "mind transfer") is the hypothetical process of scanning mental state (including long-term memory and "self") of a particular brain substrate and copying it to a computational device, such as a digital, analog, quantum-based or software-based artificial neural network. The computational device could then run a simulation model of the brain information processing, such that it responds in essentially the same way as the original brain (i.e., indistinguishable from the brain for all relevant purposes) and experiences having a conscious mind.
Mind uploading may potentially be accomplished by either of two methods: Copy-and-Transfer or Gradual Replacement of neurons. In the case of the former method, mind uploading would be achieved by scanning and mapping the salient features of a biological brain, and then by copying, transferring, and storing that information state into a computer system or another computational device. The simulated mind could be within a virtual reality or simulated world, supported by an anatomic 3D body simulation model. Alternatively, the simulated mind could reside in a computer that's inside (or connected to) a (not necessarily humanoid) robot or a biological body.

https://en.wikipedia.org/wiki/Quantum_mind
The quantum mind or quantum consciousness hypothesis proposes that classical mechanics cannot explain consciousness. It posits that quantum mechanical phenomena, such as quantum entanglement and superposition, may play an important part in the brain's function and could form the basis of an explanation of consciousness. It is not a single theory, but a collection of hypotheses.<...>
Criticism
The main argument against the quantum mind proposition is that quantum states in the brain would decohere before they reached a spatial or temporal scale at which they could be useful for neural processing. This argument was elaborated by the physicist, Max Tegmark.

Stuart Hameroff (born July 16, 1947) is an anesthesiologist and professor at the University of Arizona known for his studies of consciousness. <...>
Hameroff was inspired by Penrose's book to contact Penrose regarding his own theories about the mechanism of anesthesia, and how it specifically targets consciousness via action on neural microtubules. The two met in 1992, and Hameroff suggested that the microtubules were a good candidate site for a quantum mechanism in the brain.

It is interesting to note that a lot of pseudoscientists claim that high level of intelligence (or the possession of “consciousness”) is needed in order to possess abstraction capabilities, however it is very easy to disprove this claim.
We will remind that all organisms are able to distinguish “food” from “non-food”.
However “food” and “non-food” are abstract objects.
And that means that all organisms have abstraction capabilities.

https://en.wikipedia.org/wiki/Abstraction
Abstraction in its main sense is a conceptual process by which general rules and concepts are derived from the usage and classification of specific examples, literal ("real" or "concrete") signifiers, first principles, or other methods. "An abstraction" is the product of this process — a concept that acts as a super-categorical noun for all subordinate concepts, and connects any related concepts as a group, field, or category.
Conceptual abstractions may be formed by filtering the information content of a concept or an observable phenomenon, selecting only the aspects which are relevant for a particular purpose. For example, abstracting a leather soccer ball to the more general idea of a ball selects only the information on general ball attributes and behavior, eliminating the other characteristics of that particular ball. In a type–token distinction, a type (e.g., a 'ball') is more abstract than its tokens (e.g., 'that leather soccer ball').

Below is the classical typical example of pseudoscientific claims about “consciousness”.
Pseudoscientists Christof Koch and Giulio Tononi claim that “any system with integrated information different from zero has consciousness”.
In other words, pseudoscientists Christof Koch and Giulio Tononi claim that CD-ROM disk and USB flash drive do have consciousness. It is quite obvious that pseudoscientists Christof Koch and Giulio Tononi do lack neurons in the brain areas responsible for logical thinking.

Where does consciousness come from? We know it exists, at least in ourselves. But how it arises from chemistry and electricity in our brains is an unsolved mystery.
Neuroscientist Christof Koch, chief scientific officer at the Allen Institute for Brain Science, thinks he might know the answer.
<...>
Koch: There’s a theory, called Integrated Information Theory, developed by Giulio Tononi at the University of Wisconsin, that assigns to any one brain, or any complex system, a number — denoted by the Greek symbol of Φ — that tells you how integrated a system is, how much more the system is than the union of its parts. Φ gives you an information-theoretical measure of consciousness. Any system with integrated information different from zero has consciousness. Any integration feels like something WIRED: Ecosystems are interconnected.
A Neuroscientist’s Radical Theory of How Networks Become Conscious
By Brandon Keim. Wired. November 14, 2013

“Consciousness” is the hallucinatory object that exists only in the imagination of the religious adepts, and this hallucinatory object has nothing to do with science for a very simple reason – there is no laboratory test which can determine if the concrete object X has consciousness or not. In other words, there are no scientific criteria for determining whether the object X has consciousness or not.
“Consciousness” is the hallucinatory object similar to hallucinatory objects like “chakras”, “astral cord”, "energy egg", all sorts of subtle bodies (etheric, astral, mental, buddhic, atmic, and so on), etc.
The arguments about the existence of the “soul/spirit” and the arguments about the existence of the “consciousness” – both are identical, there is no difference between them.
