The concept of the Mind contains a paradox. Everyone seems to understand what it is about,
but when it comes to concrete answers about what it is, everything fades into a fog of uncertainty.
Perhaps, we should start by asking the right questions. The article formulates these questions and
begins the journey of building a model of the Mind as an attempt to answer them.
Keywords: consciousness, mind, hard problem, physical basis, signal processing
“Despite millennia of analyses, definitions, explanations and debates by philosophers and
scientists, consciousness remains puzzling and controversial, being at once the most familiar and
most mysterious aspect of our lives. Perhaps the only widely agreed notion about the topic is the
intuition that it exists. Opinions differ about what exactly needs to be studied and explained as
consciousness … Today, it often includes some kind of experience, cognition, feeling or
perception There might be different levels or orders of consciousness, or different kinds of
consciousness, or just one kind with different features. Other questions include whether only
humans are conscious or all animals or even the whole universe. The disparate range of research,
notions and speculations raises doubts whether the right questions are being asked” (Wikipedia
“Consciousness”).
We have to decide what questions we ask. Asking the right kind of question is a good start for
any study.
Here is how the modern philosopher David Chalmers formulated the question: “It is undeniable
that some organisms are subjects of experience. But the question of how it is that these systems
are subjects of experience is perplexing. Why is it that when our cognitive systems engage in visual
and auditory information-processing, we have visual or auditory experience: the quality of deep
blue, the sensation of middle C? How can we explain why there is something it is like to entertain
a mental image, or to experience an emotion? It is widely agreed that experience arises from a
physical basis, but we have no good explanation of why and how it so arises. Why should physical
processing give rise to a rich inner life at all? It seems objectively unreasonable that it should, and
yet it does. If any problem qualifies as the problem of consciousness, it is this one. In this central
sense of “consciousness,” an organism is conscious if there is something it is like to be that
organism, and a mental state is conscious if there is something it is like to be in that state”
(Chalmers, 1995).
Chalmers is not the first and the last one to ask the fundamental ontological question about the
Mind, and no one ever thought it to be an easy one. But his statement that the problem is hard
produced such a ‘wow effect’ because it was pronounced at the right time and in the right place.
The time has come to remind the scientists that while they tried to sweep the question under the
carpet, it has not disappeared anywhere.
Postulating the “hard problem of consciousness,” Chalmers asks why and how subjective
experience arises. These are two separate questions. ‘How’ is a strict technological question. It is
not an easy but a soluble task. We can say that if we cover technological issues sufficiently for
understanding the process, we will answer the question. But ‘why’ is ambiguous. If we look at
‘why’ as a functional question, it contains the answer.
Question: Why, when our cognitive systems process signals coming through sight and hearing,
do we have visual or auditory experience? Answer: Our cognitive systems create signals’
representations which are the experience. Question: Why does physical processing give rise to a
rich inner life? Answer: A rich inner life is the physical process of coding signals into
representations. Question: Why does the brain produce consciousness? Answer: The function of
the brain is to carry out the processes that we call consciousness.
Of course, there are many aspects to the process, and the brain is not an easy object of study.
But conceptually, the question is not hard. It is even trivial if looked at from the functional side.
That is what Chalmers calls the easy problem. His point is that ‘why’ is not a functional question.
Here is his argument: “Why should physical processing give rise to a rich inner life at all? …
What makes the hard problem hard and almost unique is that it goes beyond problems about the
performance of functions … Why is the performance of these functions accompanied by
experience? A simple explanation of the functions leaves this question open … Why is it that when
electromagnetic waveforms impinge on a retina and are discriminated and categorized by a visual
system, this discrimination and categorization is experienced as a sensation of vivid red? We know
that conscious experience does arise when these functions are performed, but the very fact that it
arises is the central mystery … To explain experience, we need a new approach” (Ibid).
Chalmers is asking why consciousness happens at all. This is the problem for him. Nothing we
will say about how the brain produces subjective experience will satisfy the philosopher.
What does Chalmers suggest as a new approach? He calls his position “naturalistic dualism.”
The term sounds new but rings an old bell. He tries to convince us that the only way of solving the
hard problem is to acknowledge that that Mind is some fundamental entity that “goes beyond what
can be derived from physical theory, … over and above the properties invoked by physics” (Ibid).
That does not sound new at all. It is the ‘good’ old dualism. But Chalmers says that “it is an
innocent version of dualism, entirely compatible with the scientific view of the world … Nothing
in this approach contradicts anything in physical theory; we simply need to add further bridging
principles to explain how experience arises from physical processes” (Ibid).
This really sounds like a hard problem: we should explain something that is beyond physics by
physical principles. Explaining physical phenomena by non-physical entities is an old tradition
and an easy way out. But the other way around is something new. That is why the philosopher
insists that “the moral of all this is that you can’t explain conscious experience on the cheap” (Ibid).
We should become dualists and monists, idealists and materialists, mystics and scientists
simultaneously. It is an oxymoron that produces cognitive dissonance. The moral of all this is that
the philosopher sets an impossible task. It is not solvable, cheaply or expensively. Here we should
just agree with Chalmers that scientific methods “must fail” (Ibid). The reason is simple:
explaining non-physical phantoms is not within the scope of science. Let them remain within the
purview of philosophy and theology. The scientific community should go on with building a
physical model of the Mind as a physical phenomenon. There is no dissonance in this position,
only harmony.
Any scientific explanation should be based on hypotheses about a physical mechanism that
could be confirmed or refuted. If the model does not have this attribute of a scientific theory, it
may be due to insufficient accuracy in defining the laws and mechanisms or the presence of
unknown factors that determine the behavior of the phenomenon under study. In this case, it
remains only to admit that there is no satisfactory scientific explanation yet.
According to another modern philosopher, Joseph Levine, this is precisely what happens in the
study of the Mind: there is an explanatory gap because we lack an explanation of the mental in
terms of the physical (Levine, 1983).
Suppose we say that the Mind is a non-physical thing that has settled temporarily in the physical
body. In this case, we answer the ‘what’ question but not the ‘how’ question about the principles
and mechanisms of operation. If we declare that the Mind is some “fundamental property” of the
world, we create the illusion of an answer as it still misses the goal of explaining how it works.
That is why there is no difference between classic dualism and modern “innocent dualism.” Both
versions are incompatible with the scientific view of the world, and both are cheap explanations.
Here is how Chalmers justifies his call to declare consciousness a fundamental property: “In
physics, it occasionally happens that an entity has to be taken as fundamental. For example, in the
nineteenth century it turned out that electromagnetic processes could not be explained in terms of
the wholly mechanical processes that previous physical theories appealed to, so Maxwell and
others introduced electromagnetic charge and electromagnetic forces as new fundamental
components of a physical theory.”
But the fact is that Maxwell’s model did not give an explanation. It was a purely
phenomenological model that described the observables well but did not explain the underlying
mechanism. He had to use the concept of force precisely for the lack of an explanation. It is the
same as using the concept of spirit or god responsible for the phenomena. He understood it
perfectly well and, as a true scientist, was not too proud of the fact. Uncovering the mechanism of
energy interactions remains a central topic in theoretical physics. So, once again: declaring
something fundamental and thus avoiding the task of explaining the mechanism is a cheap way
out.
The question of how our subjective experience arises is about how our brain produces verbal,
visual, sound, gustatory, tactile, olfactory, proprioceptive, interoceptive, painful, motor, and other
representations. But for a dualistic position, how the brain performs this function and how the
experience arises are different things. Moreover, the technological question ‘how’ is entirely
obscured by a shade of indefinite ‘why.’ This leads to a lot of fog about the “central mystery,”
which is accompanied by sloppy handling of strict technical terms. It is fine if we want to
philosophize about the transcendental and fundamental, but it is a dead-end for answering the
practical questions.
For example, Chalmers equates signal processing with information processing. This category
mistake is not as insignificant as it may seem. Strictly speaking, our brain processes signals and
generates information as code patterns that represent these signals. The quality of deep blue is a
representation of a particular spectrum of light reflected from an object and perceived by the visual
system. The sensation of middle C is a representation of sound vibrations of a specific frequency.
From this technological perspective, it is not perplexing that “there is something it is like” to
experience a mental image because a representation is an image and subjective experience.
The question “why is it that when our cognitive systems engage in visual and auditory
information-processing, we have visual or auditory experience” does not make sense because
signal processing done by the brain produces information that is the experience. But if we think
that information created by the brain and subjective experience are separate things (as Chalmers
suggests), we can go on wandering about their causal relationship forever.
The lack of progress in explaining the physical mechanism of the Mind has fed all kinds of
dualisms. Classical dualists say that it is something non-physical. New ‘naturalistic dualists’ say
that it is over and above or beyond the physical.
Suppose we agree “that experience arises from a physical basis, but we have no good
explanation of why and how it so arises.” Do we need to dive into deep but essentially cheap
dualistic metaphysics, as he suggests? No, we just have to find a good, physically substantiated
explanation. And this is not a cheap way out. We have to show what the representations are
physically and what mechanism creates this subjective experience.
The question “What is the Mind?” implicitly contains the question “How does it work?” And it
is not an idle philosophical issue but a practical task: we have to know the workings of the Mind
to be able to fix its pathologies.
Asking the right kind of questions about the object of the study is vital for success. But we seem
to forget that for the search to go in some direction, the object must be defined.
Here is what the International Dictionary of Psychology states: “The term is impossible to
define except in terms that are unintelligible without a grasp of what consciousness means
Consciousness is a fascinating but elusive phenomenon: it is impossible to specify what it is, what
it does, or why it has evolved. Nothing worth reading has been written on it” (Sutherland, 1989).
It is an honest confession about a failure of science named “knowledge of the mind” (from
Greek psyche-logos). A science that cannot define the central object of the research finds itself in
an awkward situation: the question arises — is it a science? Theoretical and practical research in
psychology interprets the Mind’s manifestations but does not explain the underlying physical
mechanism. That is why any model may claim to be right, but it is impossible to confirm or refute
it. Psychology is considered by many to be a pseudoscience precisely for this reason.
On the other side, there are various directions of brain research that are now generally called
neuroscience. For a long time, neuroscientists pretended not to be involved with the question about
the Mind. They even avoided the term whatsoever. If there is no question, no answer is needed.
But the Mind does not disappear. On the contrary, it stubbornly ‘knocks on the door’ and requires
attention.
By the end of the 20th century and the beginning of the 21st century, the situation began to
change: researchers realized that the central object of study is the Mind. Now everyone seems to
write about the Mind but still avoiding any definition. One gets the impression of its elusiveness
for scientific knowledge.
The mystics triumph and say something like this: so many efforts did not lead to anything
because the Mind is transcendent, immaterial and unknowable. But another logical chain is
possible: if the previous efforts had no result, perhaps this means that they did not go in any
direction. It is not surprising if the goal is not determined.
The reason for avoiding the definition is not only the phenomenon’s complexity but the fear of
error and responsibility. If you designate the goal, there is a significant risk of an obvious miss. If
the target is blurred or not set at all, then you can shoot anywhere and declare that the target has
been hit. There is another trick in this approach: the hope that you will hit something sooner or
later if you shoot long enough in all possible directions. Both methods combine quite well and
even complement each other. But there is another option: to clearly define the target and train the
accuracy of the shot. You risk being ridiculed when you miss. But there is hope for a result that
will be obvious to both the shooter and the observers.
The dictionary author was right that we cannot define the Mind if we do not grasp its essence.
But he was wrong that “it is impossible to specify what it is, what it does, or why it has evolved.”
We will grasp the essence when we start answering precisely these questions. Physical aspect:
what is it? Teleological aspect: what purpose does it serve? Functional aspect: what does it do?
Technological aspect: how does it do it? Only a theory that answers all these questions can claim
to cover the explanatory gap between mental and physical.
Teleological Transduction Theory makes, probably, the first attempt in the history of science
to give a clear and physically grounded definition of the Mind followed by a detailed explanation
of its mechanisms covering the above questions. This model of the Mind is closely linked with the
Theory of Energy Harmony as the model of Matter. They are developed in the research series
“Symphony of Matter and Mind” (Tregub, 2021). The author hopes that it is worth reading.
Another quote from Chalmers can be a slogan for both theories: The principles of simplicity,
elegance, and even beauty that drive physicists’ search for a fundamental theory will also apply to
a theory of consciousness” (Chalmers, 1995).

Answering the questions about the physical nature of representations (qualia, phenomenal experience) would be closing the oldest problem in the philosophy of the mind: the "explanatory gap" (Levine, 1983) between the mental and the physical, the "hard problem of consciousness" (Chalmers, 1995). The hard problem should be addressed from the physical and technological point of view to become not an easy but solvable task (Tregub, 2022). ...

How does the brain create a coherent model of reality while maintaining each signal identity and at the same time preventing the world picture from falling apart into separate pieces? In neuroscience and philosophy of mind, this question is called a binding problem. The article reveals various aspects of the problem and offers a solution based on the Teleological Transduction Theory.
Article
To make progress on the problem of consciousness, we have to confront it directly. In this paper, I first isolate the truly hard part of the problem, separating it from more tractable parts and giving an account of why it is so difficult to explain. I critique some recent work that uses reductive methods to address consciousness, and argue that these methods inevitably fail to come to grips with the hardest part of the problem. Once this failure is recognized, the door to further progress is opened. In the second half of the paper, I argue that if we move to a new kind of nonreductive explanation, a naturalistic account of consciousness can be given. I put forward my own candidate for such an account: a nonreductive theory based on principles of structural coherence and organizational invariance and a double-aspect view of information.
