INTRODUCTION.
In this essay I initially outline what is
usually meant when the word ‘mind’ is ordinarily
used in natural language, and what is meant
by the word when it is employed by psychologists,
philosophers, scientists and others involved
in the study of the human brain or artificial
intelligence.
I will then go on to argue for the non-necessity
and non-existence of ‘Mind’ as an extraneous
ontological duality of the brain, and offer
my views as to the essential non-reductivity
and non– intertheoreticality of the concept
of ‘mind’ and the necessity for a complete
elimination of the myth of ‘mind’ as being
counter-productive to a modern understanding
of human cognition.
By the term ‘intertheoreticality’ I mean
the practice of rephrasing or reshaping a
description of some older theory by means
of describing it or redefining it in another
form. Thus to rename soul to 'mind' or salt
to sodium chloride does not alter the import
of the meaning of the word nor metaphysical
nature of the concept nor the chemical composition
of the compound. In a similar way for a functionalist
whose notions are rooted in Aristotle's conception
of the soul, [1] to redescribe the age-old
dualistic notion of ‘mind’ as something that
exists in the form of a non-physical substance
- to something which depends not on its internal
constitution, but rather on the way it functions,
or the role it plays does not alter anything
other than describing the way it works rather
than the way it is entitically. [1. Levin.
2006]
The essay will end is a summing-up or conclusion
in which I will draw together all the various
argumentative strands and offer my opinion
as to why in the twenty-first century the
notion of 'mind' should even remain as an
issue or subject of philosophical exploration,
and why it has not sunk out of favour as
a concept along with similar myths like phlogiston,
the flat earth, the geocentric universe,
humours and homunculi, the acquisition of
virtues through cannibalism, telegony and
tailed men and other misbegotten peculiarities
of human misunderstanding. As Patricia Churchland
points out to dualists:
| 'It cannot be the obligation of new theories
to predict how ignorant cultural epochs may
happen to conceive of the complex phenomena
in their explanatory domain.' 2. [Churchland 2000.] |
There is widespread disagreement in the domain
of the Philosophy of 'Mind' and the science
of Robotics between the concept of an incorporeal
'mind' and the intelligent material meatiness
of the human brain or the metal and silicone
components of a robot, with the subsequent
ability to gather information, process, understand,
retrieve, profit and change existential modes
from its sensorial experience of the world.
The foregoing are practical matters concerning
the registration of material change in identifiable
objects on the one hand and the transcendentalist,
ideas of ‘mind’ on the other, which is a
spiritualistic and basically non-scientific
concept. As my own neuro-physiological and
neuro-philosophical position is one that
rejects the very idea of 'mind' in general,
it follows that I also reject the concept
of human or robotic 'minds' in particular.
In common parlance the 'mind' is taken
to
be the whereabouts of the faculty of
reason,
the seat of our inherent cognitive
or perceptual
powers which is responsible for one's
thoughts
and feelings.
The ontological question which we are concerned
with in the philosophy of 'mind' whether
we are addressing the human or the robotic
'mind' is really the so-called 'mind'-body
problem. Those dualist philosophers who attempt
to reduce so-called 'mental states' to neurobiological
states claim that the brain produces subjective
experiences that in turn can affect the brain,
though they are not in themselves identifiable
with any properties of the brain itself.
If one questions the mechanism by which
the
admittedly non-existent 'mind' is joined,
connected or brought to bear on the
material
meatiness that is the brain they fall
silent.
It is as if we asked a carter how one
could
connect a horse to a non-existent waggon,
or a sailor to explain how he would
go about
tying-up a ship to the quayside with
a non-existent
rope.
Dualism responds that our ‘mental states’
are states of a non-physical substance.
They
seem oblivious to the fact that the
terms
'physical' and 'substance' are interchangeable
words for 'that which has mass and
occupies
space.' So the expression: 'non-physical
substance' is a contradiction in terms.
Dualism
does not provide any answers to more
specific
questions about the nature of the so-called
'mind,' such as precisely where it
is located?
How it manages to remain extant during
the
course of our lifetime if it has no
means
to absorb sustenance or no blood vessels
to be re-oxygenated etc?
Using for example the qualia of pain as an
example of a mental state, Behaviourism sidesteps
our question in a word, namely: 'behaviour.'
For them what is common to all pains in virtue
of which they are pains, for example, is
that people respond to pain by tending to
act alike. This is interesting but irrelevant
to the question – for the question of ‘mind’
is a question of 'mind' – brain or 'mind'–
body connectivism and not what the observed
results of an unexplained ‘mind'-body connectivist
assumption involve.
The question as to what process is involved
which enables pain to become joined or united
or linked to ’mind’ or how the pained physical
object [say a finger hit with a hammer] with
the 'mind' state of registering and feeling
the pain which results in all people acting
alike? A learning ‘mind’ able to process
actionable knowledge) would need to be concentrated
on associating particular informational data,
and the for the connections that allow us
to gain knowledge or skills are more are
more important than our current state of
knowing – hence the demise of the Neanderthal.
Identity Theory claims that neurophysiology
is what all pains share that makes them pains.
To be in pain is to have one's C-fibres firing.
This neatly avoids the question of how the
materially existent meaty C-fibres are connected
with the non-existent substance that is claimed
to be the 'mind' or consciousness that records
the pain.
Using the same example of pain we discover
that Functionalism says that what all
pains
share in virtue of which they are pains
is
their functional role--namely, their
relation
to inputs, outputs, and other functionally
defined mental states. Again there
is no
attempt by functionalists to explain
the
vitally important ontological explanation
as to how the functional input of the
physically
meaty toe's change of existing from
that
of a healthy whole toe to that of a
damaged
toe pierced by a three inch nail is
converted
into a non-existent 'mental state'
of some
non-existent 'mind.’
Once again to address the question: Do Robots
have 'Minds?’ directly my answer is no. Robots
do not and never will have 'minds' no matter
how ingeniously they are developed by their
human creators. Even if their human creators
succeeded in such a faithful replication
of such humanoids that they were so perfect
as to be virtual copies of humans they would
never have ‘minds', because their human engineers
have no ’minds’ to be copied, emulated or
simulated. Like there are conscious (aware)
humans there will one day be sensorially
aware robots or humanoids but ‘consciousness’
itself does not exist. There may well be
‘mindful robots’ as indeed there are ‘mindful
human beings,' but that does not mean that
a ’mind’ exists which is linked to the meaty
or metal bits by some inexplicable chain
of metaphysical conjunction or co-occurrence.
The bottom line?

To return to my introduction. Why in the
twenty-first century the notion of 'mind'
should even remain as an issue or subject
of philosophical exploration? My answer to
that question might well form the subject
of a separate essay, but in short I believe
it is because so much of our traditional
belief has been invested in the idea. Religion
for example does not take kindly to the idea
that the ‘mind’ does not exist, for ‘mind’
and ‘soul’ are inextricably linked in theological
doctrine. So too with the enormous ‘psychology
industry’ with a turnover in the United States
of billions of dollars annually. Much of
medical psychiatry still accepts the notion
of 'mind', although it pragmatically relies
almost completely upon treatment by drugs
and chemicals that affect the material tissue
of the embodied brain and not some notional
non-existent ‘mind.’ There conclusion for
me is obvious. If no such connection exists
between the non-existent human or robotic
'mind' then anything which is aid to exist
or to be actual which is dependent on such
a non-existent ‘mind’ itself does not exit.
Therefore so-called ‘qualia’ do not exist.
What exists is the painful finger or toe,
the conscious human mentating robot – but
though it may seem counter-intuitive – ‘pain,
consciousness, and mentation do not exist
in the world – what exists is the pained
human being.
The bottom line? For me counter-intuitiveness
and the habit of challenging preconception
are important additions to any philosopher’s
tool-kit. My experience tells me that
reasoning
and empirical observation are vastly
superior
and more reliable than opinion arrived
at
through a vague idea in which some
confidence
is placed that humans have ‘minds'
and that
one day perhaps robots might have ‘minds’
too.
