IN SEARCH OF THE MIND
By Jane Cull
BETTER LATE THAN NEVER, BETTER SOMETHING THAN NOTHING
by Paul Jones
10 January 2000
One might find it remarkable that the KJF enters year 2000
discussing two articles defending the same idea that no
mind can be found in the brain, and consciousness is rather
to be sought in the complexity of human relations.
Though differing in their line of reasoning, Timo Jarvilehto
(TJ) and Jane Cull (JC) come to the statement formulated by
K.Marx nearly 160 year ago and defended by many scientists
and philosophers in the former USSR.
Recognizing the "non-bodily" nature of the mind, one
definitively overcomes the vulgar view that consciousness
could emerge in a single organism as an implication of its
internal complexity; on the contrary, one asserts that
no individual, however complex it may be, can develop
anything like consciousness on itself, without being
assimilated in a higher-level formation mediating all
the processes occurring between the organism and its
environment. This indispensable framework is provided
to every person by culture, the embodied history of human
activity.
Still, deliberately quitting with primitive materialism,
one encounters a number of serious problems:
- One has to demonstrate that the mind can be considered as
a property of the material world, and there is no need to
ascribe it to a mystical something beyond human understanding.
- One has to retain the specificity of the mind as different
from other life, or inanimate motion.
- One has to explain how a conscious being could be
distinguished from lower-level phenomena, and how one
must behave to be called a conscious person.
In my opinion, TJ and JC suggest an acceptable answer to
question 1, being less coherent in the other two.
There is no mind in the brain. As JC bluntly formulates it,
if you were to open up the brain you would not find a mind
in there. Firing neurons, slow potentials, chemical reactions
and tissue metabolism can tell little about the conscious
action they implement. One has to always go from the known
activity to its organic correlates, never in the inverse
direction. Moreover, the same activity can be implemented
in quite different ways in different individuals, and one
might expect the organic support of consciousness to be
dependent on the living conditions, so that a conscious
inhabitant of some other planet, or an intelligent computer,
would not necessarily demand the same physiology as in humans.
Whatever happens in the human body, and in the brain, is
determined by its structure (JC). The body functions
differently in different environments, and, in some
circumstances, it may be treated as a mere physical body
occupying that much space and weighing that much (for
instance, in engineering); in some other respect, it may
be considered as a purely biological formation (e.g. in
surgery). That is, to function as a carrier of consciousness,
an individual must be put in the special conditions, which
would prompt the brain and the body to behave in an
appropriate way. Certainly, the system has to achieve
a rather high level of organic complexity to be able to exhibit
conscious behavior, and no conditioning can make conscious
an animal that is too primitive for that. This also implies
the necessity, once in a while, to consciously change the
design of the human body, to allow further development of
consciousness.
The latter is a manifestation of the general trend:
the higher levels of a hierarchy influence lower-level
behavior. Thus, a person as a physical system will
move differently from an inanimate body of the same
form made of the same material (e.g. the dead body),
which may be used, say, in criminalistics; moreover,
the observable biological behavior of a conscious person
is often significantly different from mere biological
acts, and it is this difference that allows, for instance,
a court to judge on a person's responsibility.
Not only the operation of a body as an implementation
of a conscious being demands appropriate conditions,
but also the very formation of a conscious person
entirely depends on the environment. The hierarchy
of "prompts" provided by the culture (including both
material culture and social intercourse) directs the
development of a child in a quite definite way,
and any organic peculiarities influence the development
of the personality through the (direct or indirect)
society's reaction on them.
Inversely, a conscious being can exist as such only
in the society, and the personality is bound to degrade
without any human contact, at least very distant and
indirect.
Hence the natural conclusion that
"...the human essence is no abstraction inherent in each
single individual. In its reality it is the ensemble of
the social relations." (K.Marx),
or:
"The thinking and consciousness subject is not a piece of
flesh, but a set of relations and processes in the social
system." (TJ),
and:
"The mind is not in the head, the mind is in behavior."
(Maturana, as quoted by JC).
That is, consciousness is a specific way of the operation
of the human (so far) society. TJ follows Marx in that
there are different levels of consciousness, from a
general feature of social dynamics down to individual
consciousness, which may (but does not necessarily need to)
be associated with a particular human body in a definite
social environment. The projection of the social dynamics
on the functioning of the body (and the neural processes
first of all) forms subjective experience; this experience
is hierarchical as well, including the reflection of
the activity of the society as a whole, the activity of
various social groups, and eventually the society-mediated
behavior of the individual. However, the person may be
unaware of many social processes, and it is only a part
of them that contribute into the conscious component
of a subjective experience, the rest forming the domain
of the unconscious.
The important corollary is that human thoughts and deeds
are not entirely arbitrary, being an aspect of a
higher-level process, social dynamics. One could put
it differently: a person's behavior can be called
conscious only to the extent of its consistency, all the
rest of behavior representing the lower-level components.
Such non-conscious elements should be distinguished from
the unconscious components, since the latter still reflect
certain levels of social consciousness, while the former
have nothing to do with social activity at all.
To study consciousness and personality, one has to
analyze the social relations, while the organic and
physical contributions in the observable behavior are
to be described in the appropriate biological or
physical (chemical, ...) terms respectively.
This puts the study of consciousness in the same row
as the study of any other phenomenon: there is something
to study, and a number of observers, whose observations
differ since they belong to different frames of reference;
however, the frame-dependent aspects are never relevant
for collective action, which is the only substrate for
consciousness and knowledge. In the same way, the
possible observer's influence on the things observed
is readily eliminated by the consideration that the
required applications necessarily involve the same
interference, reproducing that very set of relations
between the object and the subject as an invariant,
which is the basis of (inter-)mental consistency.
There may be different models of the formation of
consciousness in social and individual development
(but never mere biological evolution or growth).
All such models have to incorporate the individual's
dependence on the society as the foundation of the mind.
This invokes the question of the boundaries of the
person and personality. As TJ indicates, the boundary
of the body should not be (mis)taken for the boundary of
the conscious being (and even a mere living creature),
since the functioning of such a system implies that
certain parts of the environment have to be drawn into
its operation as significant constituents. However,
in every particular respect, one might indicate the most
relevant relations that outline the personality in the
cultural space, which is different from the physical
space-time, though related to it. This is like a quantum
system may be difficult to locate in the macroscopic
space of the observer, while occupying a quite definite
position in the Hilbert space of the possible quantum
states.
Since all the cultural phenomena have to be embodied in the
products of human activity, a volume in the cultural space
occupied by an individual may be measured by the scope of
products (both material things and cultural habits) at the
person's disposal, including indirect usage through
cooperation with the other individuals. The ensemble of
such products constitutes the inorganic body of the person
(K.Marx, E.Ilyenkov). The existence of a localized formation
in the cultural space is a necessary premise of individual
consciousness.
Certainly, the person's boundary in the cultural space may be
rather diffuse which, however, does not invalidate the very
idea of localization (e.g. as a distribution with a well
pronounced maximum). Under certain social circumstances, the
boundary may be rather steep, acting as a kind of surface,
or a membrane. In any case, it does not coincide with the
boundary of the human body, which is only one of the products
available.
That the mind does not sit in the human body does not mean that
there is no boundary at all, and no inside and outside merely,
these are not the inside and outside of the physical body of
the person. Also, though infinite extensibility is a fundamental
feature of consciousness, any person is well localized at any
time, in the cultural space. In any case, the mutual penetration
of the system and its environment, or the mutability of their
distinction, cannot be a determinative characteristic of
a conscious being.
As TJ indicates, an organism cannot exist as such without its
environment, and it is the processes occurring between the live
body and its environment that constitute life itself. However,
one could object against the identification of the system with
its structure, which leads to much confusion and inconsistency.
In the applications, a system is always characterized by its
functioning, linking the input to the output this systemic
relation does not imply a unique internal structure, or a
definite feedback configuration though, certainly, there
may be limitations on the class of structures supporting that
particular kind of behavior.
TJ is right in principle, when considering the parts of the
external world providing the input and output, or effectuating
a feedback, as the indispensable components of the system's
functionality; however, one could readily observe that
this is in no way specific for the living systems, and all
the inanimate systems function that way too. The principle
of operational closure formulated by JC can be generalized
from the nervous system to any system at all, which operates
according to its internal laws until it gets subject to an
external influence triggering a different mode of operation.
The functioning of a mechanical watch, as suggested by TJ,
may seem to be quite different from the functioning of a
living organism but let us turn to the case of a solar clock
to instantly discover the dependence on the external bodies
as the necessary condition of functioning, which TJ claims
to be characteristic of life. A thermometer cannot show
temperature without being immersed in some medium; a string
cannot sound without the air, a laser cannot fire without
being pumped... Well, the computers we are all working with
cannot work without power supply and some control sequences
fed in from the keyboard or the mouse.
It is the thing's structure that determines what it can be.
It is the thing's involvement in the outer world that makes
it what it appears to be, a system. Finally, the hierarchical
view is to synthesize both structural and systemic approach
to tell what the thing is going to be, how it can develop.
All the three aspects are necessary to understand what the
thing really is.
Since we do not want to claim the whole nature live and thinking,
we have to explain how life is different from not-life, and
what thinking adds to mere biology. TJ has suggested that
the answer is to be sought in the thing's relation to its
environment; he has also indicated that the level of life
should be characterized by a less rigid boundary between
the two. However, he did not follow this line far enough
to show the distinction between life and reason.
I doubt that one could completely characterize the levels
of inanimate motion, life and reason using a single
criterion rather, there is an infinite number of possible
dimensions, and the distinction is to be specially traced in
every particular respect for instance, in the definition
of the "system" and "environment". However, there may be
more favorable dimensions, where the hierarchy of the physical,
the biological and the conscious is much clearer than in
the other aspects.
No system can be defined without specifying its relation
to the environment. However, we could distinguish three
general types of such relations:
1. Interaction.
The interacting systems do not play different roles in
their interaction; they enter it on equal footing, and
in a random manner, so that a system is indifferent to
the sequence of interactions it may participate in.
Thus, it does not matter for an electron whether it will
first interact with a proton and then another electron,
or in the inverse order the actual succession is
determined by the external (kinematic) factors that do not
depend on or influence the system's functionality.
2. Metabolism.
On this level, one finds a special kind of systems, which
are functionally selective and sensitive to the order of
interactions they enter. That is, there is a sequence of
interactions that must be regularly reproduced to maintain
the system's existence, and there are interactions that
must be avoided. When such systems form a higher-level
ensemble, where the conditions for their existence are
reproduced in a well-balanced chain of interactions, the
hierarchical system thus formed can support life.
3. Activity.
On this level, the environment required for the metabolism
of a special kind of live systems ("individuals") is produced
by the other systems of the same kind. That is, a thing
to be consumed by an individual is to be first processed
by another individual and become a product. The degree of
this processing will rapidly increase due to "cascading",
when the things processed are already products of somebody
else's activity. Now, every individual sees in a
thing not only what it can be used for, but also its
artificial origin: it has been made, and hence can be
made); in the primitive forms, such an attitude may be
transferred to all the world, so that natural things get
treated as made by somebody. Any activity involves three
kinds of things: products (something that appears as a result
of activity and gets used in another activity), subjects (the
individuals involved in production), and objects (something
that is used for production);
The above distinction allows both to stress the difference
between the physical, biological and conscious levels, and
to indicate how various intermediate forms could appear in the
process of their formation. There are no strict borderlines,
and any real thing can mix different levels in it. Thus,
a person can combine the elements of conscious behavior with
numerous relics of the animal, and an inanimate thing can
simultaneously be a product of some activity and hence a
carrier of certain cultural functions and subjectivity.
That is why the ethical aspect is so important in the
philosophy of consciousness.
While TJ does not explore the ethical consequences of his
theory, JC tries to suggest (mainly on her Web site) a line
of behavior that seems to be compatible with her (and
Maturana's) views. Her motto could be expressed in a
simplified way as: "Do what you are inclined to do,
since this is what your internal structure demands."
This reflects a logically wrong implication that, since
the mind is not in the individuals, but rather in their
relations with the others, it cannot control their
behavior or impose any restrictions on it. However,
environment plays a decisive role in any system's operation,
so that quite different things can behave in a similar way
under certain conditions, and the same thing can be used
differently. The system of social relations external to
the individual's biological body is more important for
the person's behavior than any physiological peculiarities.
However, this does not contradict the fact that the system can
exhibit only the modes of behavior that are compatible
with its structure: simply, the "interior" for a
conscious person is different from mere biological body,
including the "inorganic body" as well.
With the above considerations, it can be observed that
the characteristic feature of specifically human behavior
is the transformation of any aspect of the world into a
product, and passing it to other people for further
processing. When somebody picks an apple from an
apple-tree and eats it, he/she acts as an animal
(provided there is no special consumption procedure
implying communication). When an apple picked from
the tree is brought somewhere to feed another person,
it becomes a product of the "picking-up" activity,
provided the other person can perceive it as a product.
Similar distinctions can be drawn on any other level;
for instance, working for money is an animal occupation,
while working for the well-being of the humanity
characterizes for a conscious being; for another example,
ne could look at a philosopher trying to deduce anything
from his own experiences, denying the existence of the
other people and their products, and conclude that he lacks
consciousness, exhibiting a self-centered kind of behavior
more appropriate for the animals.
Once again, it should be stressed that the same person
will manifest behavior of different levels in the same act;
however, the development of the humanity results in the
increasing dominance of the conscious component. Gradually,
people will learn to recognize the non-human tendencies
in themselves and subject them to conscious control.
