Is the brain the origin of Man's mind?
What is artificial intelligence?
Artificial Intelligence or AI is among the most recently advanced scientific
concepts. The associated field of study has been defined as follows: ‘the study
of mental faculties that encompasses computational techniques for performing
tasks which apparently require intelligence when performed by humans’ (M. S.
Aksoy, The Fountain, 1993, No.4, p.10).
Modern scientific inquiry is directed to finding analogues for human mental
activities
Besides searching for new techniques to substitute man in the fields of labor,
modern scientific inquiry is also directed to finding analogues for human mental
activities. Since their assumption is that man is merely a physical-material
entity (a complex of physical, biological and chemical processes), many scientists
are hopeful that they can produce a complete copy of human functions. It is
their assertion that since at least nothing in existing physical theories accounts
for the existence of non-computable processes in the brain, all of man’s intellectual
activities can be computed. However, Roger Penrose, the famous Oxford mathematician,
argues against this assertion. He argues from Gödel’s theorem which states that
for every consistent formal system that has the power to do arithmetic, there
will always be a true statement. That is, a formal system is a set of logical
or computational rules; termed consistent if it never produces contradictory
statements. Yet, as human beings can see that that statement is true, this constitutes
a sign that our minds can go beyond the powers of any formal system. However,
since Penrose himself (like many others who share his opinions) cannot free
himself from the confines of (materialistic) physics and nothing in existing
physical theories accounts for non-computable processes, in order to be able
to find a physical foundation for his theory, he pins his hopes on future elaborations
of the theory of quantum mechanics. In his attempt to explain human consciousness,
Penrose notes that the biggest mystery of all is how electrical activity in
the brain gives rise to the experience of consciousness. It is hard to understand
why an inner life should arise from the mere enactment of a computation, no
matter how complex. However, his alternative is not more convincing than what
he rejects. He tries to explain human consciousness with quantum processes in
microtubules—collapsing quantum wave functions (the mathematical functions describing
the position and momentum of a particle) in protein structures found in the
skeletons of neurons.
Is the physical body the origin of all activities of man’s intellect?
The main problem arises from accepting the physical body as the origin of
all activities of man’s intellect. The problem is also true for the expectations
from Artificial Intelligence. Aksoy has a simple but meaningful objection to
the assumptions underlying those expectations: ‘A man-made system can be very
smart and artificially very intelligent but no such system so far has been awarded
a prize for its innovative abilities. It is the human being who made it who
wins the prize. What is prized, what is of higher worth, is not the system but
its maker or builder.’ Another more simple objection can be raised here. For
example, after doing a spell-check on a word-processor, you may come across
many mistakes which the software has not recognized. Any sentence can be written
in several ways in which the words are correctly spelt but are not the words
you intend to use. For example, if we type the sentence ‘What is prized is not
the system but its maker or builder’ as ‘What is priced is not the system but
its make or build’, most people who know the language will recognize it immediately
and effortlessly as nonsense. But the software’s spell-check and grammar-check
will pass the sentence as OK. Such examples can be multiplied for a great variety
of tasks requiring experience and understanding which cannot be analogued or
translated for AI machines but which humans cope with quite easily.
More ‘developed’ animals must also be more developed in using their senses
and faculties or their brains but they are not always so
Another point to mention concerning man’s intellectual activities relates
to the issue of learning and education. Materialistic approaches attribute all
of man’s intellectual activities to his brain. According to the theory of evolution,
if taken literally, more developed animals must also be more developed in using
their senses and faculties or their brains. But this is not the case.
As Dr Yilmaz points out (The Fountain, No. 19, pp. 34–6), compared with a
shark which can smell a drop of blood in the sea from a distance of about 25,000
feet, man is very much less developed. If we judge the degree of development
according to the sense of smell, in place of men or monkeys, sharks will be
at the top of the chain. Whereas, with respect to the sense of seeing, eagles
are much more developed than sharks, as well as more than men and monkeys: an
eagle can spot a rabbit on the ground from a height of about 6,000 feet. Would
it not be true for a honey-bee to say of us: ‘Those clumsy ones can draw with
tools and only after calculations the hexagons that I can make so easily and
exactly identical to one another. They cannot make so sweet and healing a substance
as honey that I produce in great amounts.’ Again, according to the literal logic
of the theory of evolution, must a more developed animal not inherit the abilities
of one less developed than itself? In this case, must man not have the abilities
of all animals and must apes not have the abilities of all other animals ‘lower’
on the evolutionary ladder than themselves? Also, if man was evolved from apes,
should the first man evolved not have inherited all the abilities and knowledge
of all apes? However, we see that while all other animals are born as if educated
and instructed already in all the information they will need to survive, man
is born knowing next to nothing of what he needs to know to survive. And while
all other animals come to the world with the same information or knowledge their
predecessors had and there is negligible (if indeed any) difference between
the amount of knowledge and abilities that the members of a species have, a
man’s knowledge cannot be inherited by his progeny. Consequently, human beings
vary hugely in their intellectual and artistic capacities and the amount or
level of their knowledge.
Behaviorism and cognitivism in learning
Materialistic and evolutionist psychology consider learning either as a matter
of behavioral patterning by reinforcement or the storage and use of knowledge.
The first view is called behaviorism, while the latter cognitivisim. However,
both are agreed that it is the brain or neural systems which learn. That is,
the intellectual dimension of man’s being consists in his brain. They confuse
how a man learns with what it is that does the learning. What they want us to
believe with respect to man’s intellectual faculties is not different from defining
how a factory works. According to their logic, it is the factory itself which
built itself and works according to the laws pre-determined by either itself
or the collective being of factories. Although they use personal pronouns such
as ‘I’ or ‘You’ or ‘We’ in referring to those who learn, speak, think, reason,
decide and so on, forgetting that the brain does not know itself or what it
is doing and also forgetting that it is we—humans—who study, speak about, comment
on and even operate on the brain, they regard it as scientific to attribute
all man’s intellectual activities and faculties, and therefore his conscious
existence, to the brain. If that is so, why do we not concentrate our efforts
merely on the brain and adjust it as a way of adjusting or educating individuals
rather than go to the trouble and expense we currently go through to educate
and bring up our fellow members of society? Again, does attributing man’s intellectual
activities to the brain mean that whatever man will need in life and also his
desires, expectations, feelings, pains of the past and anxieties of the future,
etc. were pre-encoded in his brain and that according to the situations or the
stimuli coming from the outer world, the brain brings them forth as responses?
According to what we are asked to believe, the brain continually self-organizes,
learns and adapts throughout our lives. Understanding how millions of neurons
self-organize through non-linear feedback interactions requires that we have
a full grasp of the mathematics of neural networks and of how this mathematics
helps us to understand the link between brain and behavior. Is it not compounding
our ignorance to attribute to a heap of blind, deaf, ignorant flesh, blood and
neurons unconscious of themselves, of their existence and what they are doing
or why, all of man’s intellectual faculties and activities with all their complexity,
all of our consciousness and culture, religious life? Does this make sense?
And does not doing so entail a denial of man’s free will? Although some psychologists
such as Tolman and Köhler are of the opinion that at least in some cases learning
appears to be purposeful and animals and people have an awareness of what is
being acquired and they actively interpret the stimuli they sense from the environment,
since they too attribute this to the brain by asserting that there must be more
than one system in the brain involved in learning, the point on which all materialistic
approaches are agreed (consciously or unconsciously) is that man is an animal
whose acts consist in the automatic responses of his brain, an animal that has
no free will to direct and control his life.
The activity of learning is remarkably easy as both behaviorists or cognitivists
assert. Yet it is nevertheless extremely complex. Besides senses, many human
faculties such as imagination, conceptualization, reasoning, comparing, retaining,
remembering, confirming and conviction, have a share in it. Each of these faculties
give its color to what is learnt. For example, only imagination gives rise to
falsehoods, while conceptualization is ambiguous as to what passes through it.
Reasoning does not have an established view of what comes to it, while capable
of confirming partiality or prejudices pleasing to the one doing the reasoning.
Surely the materialistic approach has no right to that degree of conviction
achieved by impartial reasoning and study of real evidence and which is worthy
to be called scientific knowledge. Rather, what materialist and evolutionist
psychologists suggest may only be the product of imagination or partial (i.e.
biased) reasoning.
