This is a paper original delivered at the First Annual Mathematics
|
|
and Psychoanalysis Meeting in New York, N.Y. on June 6, 1988. Any
|
|
comments are very welcome.
|
|
|
|
What I have to say today is more by way of posing a problem
|
|
and indicating an area where I suspect the solution to lie than a
|
|
coherent presentation of a new theory. I am going to talk about
|
|
some elementary ideas from a branch of psychoanalysis called self
|
|
psychology and some elementary ideas from computer science that
|
|
seem to me to provide a framework for thinking about the self of
|
|
self psychology and then invite you all to let me know whether what
|
|
I have said has made sense and whether you can see directions for
|
|
the development of these notions.
|
|
Freud's effort to explain mental life on the basis of drives
|
|
that are the psychological representations of biological
|
|
disequilibria fell on hard times as he tried to work out the theory
|
|
in detail. He introduced a new entity, the ego, dangerously close
|
|
to a homunculus within the mind, that performed certain functions
|
|
and vigorously protected itself from being "overwhelmed" or
|
|
traumatized. The ego's functions included managing the persons
|
|
relation to reality, regulations of drives, object relations,
|
|
thought processing, defensive functions, perceptions and motor
|
|
activity, and integration of all other psychological functions -
|
|
its so called synthetic function.
|
|
The concept of the ego became the center of American
|
|
psychoanalytic theory in the forties ,fifties and sixties. Despite
|
|
heroic, rigorous efforts to sharpen the terms's meaning, the
|
|
confusion Freud left between the ego and the subjective experience
|
|
of the self continued. This persistent confusions was not merely
|
|
the result of intellectual sloppiness. Nor was it, as Bruno
|
|
Bettleheim proposes, the result of Freud's English translators'
|
|
discomfort the soul-like implications of the Freud's original idea.
|
|
The difficult is more fundamental. The terminologic and theoretic
|
|
confusion reflected a clinical reality.
|
|
It often happens that people who functioned badly in the areas
|
|
called "ego functions" also have major disturbances in their
|
|
experience of the self and that the two types of difficulty are
|
|
exacerbated or diminished in concert. The idea of the ego as a
|
|
unitary entity is not just as a convenient, if confusing, name for
|
|
the set of functions described earlier, a sort of waste basket for
|
|
what is neither id nor superego. The term reflect the commonly
|
|
observed covariation in these functions.
|
|
The systematic exploration of the self experience began in
|
|
psychoanalysis in the years following the second world war, though,
|
|
of course the concept of self has been the object of study since
|
|
the dawn of civilization. Although he had significant
|
|
psychoanalytic precursors, notably in the work of Paul Federn, Erik
|
|
Erikson was the first to propose that the core of much
|
|
psychopathology lies in disorders of self experience. Erikson's
|
|
concept of identity, which amalgamated the many sources of beliefs
|
|
about who one is is both evocative of common experience and proved
|
|
clinically useful. Many kinds of difficultly, as well a normal, and
|
|
supernormal psychological development can be usefully explored as
|
|
experiences of loss or diffusion of identity or attempts to
|
|
establish a satisfactory identity where one was lacking.
|
|
Erikson's work is problematic from a psychoanalytic point of
|
|
view for two reasons. First, reading Erikson carefully one
|
|
discovers that his wonderful portrayal of emotional states through
|
|
imagery, metaphor and clinical detail is not matched by explicit,
|
|
clear theoretical formulations. Second, his writings often focus
|
|
on external environmental effects rather than people's
|
|
psychological worlds and the manner of their construction.
|
|
Erikson never systematically described his therapeutic
|
|
approach to his patients. However, it is clear that he consistently
|
|
placed a positive connotation on his patients' struggles. He
|
|
demonstrated how manifest psychopathology could be understood as
|
|
potentially successful attempts to achieve valuable identities,
|
|
that while there might be difficulties in the way the patient's
|
|
basic project and his ways of attempting to accomplish it were
|
|
closer to healthy development than the patient or the society might
|
|
recognize. Erikson's psychobiographical studies of Luther, Gandhi,
|
|
Hitler and Shaw are messages to readers, many of them young, about
|
|
the value of their struggles to form workable identities. Erikson's
|
|
implicit view is that an appreciative stance toward the patients'
|
|
struggles which include or dominated by external realities is
|
|
therapeutic.
|
|
In the years following the second world war Harry Stack
|
|
Sullivan, observed that the experience of the self of many of his
|
|
schizophrenic patients was grossly disturbed. Borrowing from the
|
|
Chicago School of Sociology, most notably George Herbert Mead,
|
|
Sullivan conceptualized the self as a summation of social roles,
|
|
some of them retained without full awareness from archaic periods
|
|
of development. In this "interpersonal theory" of psychology
|
|
pathology resulted from a self system that was internal incongruent
|
|
or problematic in terms of the environment. Therapeutic
|
|
intervention consisted in understanding and appropriately revising
|
|
the self system in the light of more mature and current
|
|
understanding. What is central to our discussion is Sullivan's view
|
|
that the self system was both the product of the external
|
|
environment and made no sense whatever outside of a social system.
|
|
Several analysts, notably Klein, Winnicott, Khan, Fairburn,
|
|
Bion, Spitz, and Modell emphasized the role of holding environment,
|
|
environmental container or the "mother" in the development of the
|
|
self. From their very different perspectives each emphasized how
|
|
the self's growth required an external situation of being "held"
|
|
as the emerging and vulnerable self gained strength and autonomy.
|
|
People whose psychopathology centered in problematically self
|
|
development, a condition that all these authors equated with
|
|
difficulties in the first two years of life, could work out their
|
|
problems if provided with an analytic situation that allowed them
|
|
to reengage those phases with the analyst experienced as the
|
|
archaic maternal environment of that era. Some of these analysts
|
|
believed, like Melaine Klein, that these very early situations
|
|
involved inherent conflicts that now be resolved through
|
|
interpretation in analysis. Others like Donald Winnicott held that
|
|
new experiences, "beyond interpretation," with a good-enough object
|
|
were needed so that the developmental failure could be righted
|
|
through new development. The theoretical formulations of many of
|
|
these authors was either so inherently fantastic, or so abstruse,
|
|
or so unsystematic that their work has had relatively little
|
|
influence on psychoanalytic theory beyond the range of their
|
|
immediate followers. It is only now being integrated into the
|
|
mainstream of psychoanalytic thought.
|
|
Margaret Mahler and her coworkers also concerned themselves
|
|
with he early development of the self. They centered their
|
|
attention on the era of late toddlerhood that involved the
|
|
difficulties of the child emerging from a state they called
|
|
"symbiosis" in which the experience of the self includes the care
|
|
taking environment into a state of being an individual in one's own
|
|
right. Based on treatment experiences with youngsters and adults
|
|
who seemed to have difficulties in the area of the self experience
|
|
and observations of toddlers, which unfortunately were dominated
|
|
by their preexisting theory, Mahler and her group concluded that
|
|
much of the difficulty in self experience arose from a failure to
|
|
adequately separate from the mother of infancy. Although there are
|
|
many well informed analysts who would disagree with me, I will
|
|
assert that the overwhelming data of infant and later developmental
|
|
studies demonstrate that Mahler's symbiotic phase is not part of
|
|
normal development nor is separateness, in the sense she meant it,
|
|
characteristic of ordinary or healthy more mature psychological
|
|
function.
|
|
However the clinical observations that lead to Mahler's
|
|
thinking and that have been explained in terms of her theories are
|
|
certainly common. That is, there are many people who seem to have
|
|
shaky experiences of themselves and function with a conflicting
|
|
notions that on the one hand they desperately need other people if
|
|
they are to function at all reasonably and that some core aspect
|
|
of themselves is in danger precisely in these urgently needed
|
|
interactions.
|
|
Starting in the sixties in Chicago Heinz Kohut initiated a
|
|
psychoanalytic study of disorders of the self. His approach to
|
|
these researches was methodologically distinct and is worth a
|
|
moment's pause. First he took a radical position, that he claimed,
|
|
incorrectly at the time, to be a standard one, that psychoanalytic
|
|
data was collected in a manner different from that of the natural
|
|
sciences. He asserted that it is possible and usually to
|
|
immediately comprehend complex psychological configurations in
|
|
others and that such understanding ordinary mode of operation of
|
|
the working analyst. Empathy for other's internal states, as a mode
|
|
of comprehension, was, for Kohut, similar to the way we perceive
|
|
faces - as a complete and immediate gestalt. Analytic training and
|
|
technique are designed to maximize the analyst's ability to use
|
|
this investigative tool and to overcoming its pitfalls, just a
|
|
training in microscopy enables us to vastly extend ordinary visual
|
|
capacities. While Kohut claimed to be making explicit what everyone
|
|
did anyway, his position, right or wrong, was deeply antithetical
|
|
to Freud's view of psychoanalysis as a natural science-like
|
|
investigation and also Hartman's explicit statements that empathy
|
|
in the sense that Kohut meant it had no appropriate role in
|
|
psychoanalytic investigation.
|
|
A second, and less problematically, position about
|
|
psychoanalytic investigative method was Kohut's position on
|
|
transference. In his early writings on self psychology Kohut
|
|
assumed that the only data to be taken seriously in psychoanalysis
|
|
were the data of the transference. The various stories the patient
|
|
told, the analyst's conceptual framework and responses and all the
|
|
other stuff the analyst commonly use to frame a picture of the
|
|
patient's psychology was of minimal importance compared to the job
|
|
of describing and understanding the interaction between patient
|
|
and analyst. Kohut also believed that premature interpretations to
|
|
the effect that the patient was avoiding knowing something about
|
|
himself often interfered with the full blossoming of the
|
|
transference. According to Kohut, premature interpretations,
|
|
particularly premature interpretations of defense often resulted
|
|
in the analyst discovering evidence that confirmed their
|
|
preexisting notions because they misunderstood possibly contrary
|
|
clinical facts as representative of the patients' avoidance of
|
|
already known realities.
|
|
Using empathy and the exploration of transference as their
|
|
primary tools, Kohut and his students treated a group of patients
|
|
whose distress took three overlapping forms. One group of patients
|
|
suffered from feelings of depletion, emptiness, triviality and/or
|
|
fragmentation. These experiences often took symbolic expression in
|
|
the form of hypochondriasis. Another set of patients were engaged
|
|
in activities that seemed enormously driven or addictive such as
|
|
sexual promiscuity and perversion, shop lifting, desperately
|
|
clinging relations to other people and substance abuse. Finally,
|
|
some of the patients had chronic and acute states of tantrum like
|
|
rage.
|
|
In analysis, at least as conducted by Kohut and his followers,
|
|
these patients developed characteristic attitudes to the analyst
|
|
that Kohut labeled selfobject transferences. Characteristically,
|
|
often against considerable internal resistance, these patients came
|
|
to experience the analyst as essential to their well being. His
|
|
physical or psychological absence variously precipitated great
|
|
distress and/or the reemergence of symptoms that had been
|
|
previously remitted. For example, a young man who had entered
|
|
analysis much distressed by his promiscuous homosexual behavior
|
|
reported what for him was a major business success during a
|
|
session. The analyst, noting that the patient's anxiety had
|
|
interfered with an even greater accomplishment, made the plausible
|
|
interpretation that the patient had inhibited himself from doing
|
|
even better because he experienced his business competitor as like
|
|
the analyst and feared the analyst's reprisal if the patient beat
|
|
him in competition. The interpretation was bolstered by several
|
|
significant details that made it plausible and the patient thought
|
|
it was "right on the mark" and promised "to try to do better next
|
|
time." Retrospectively he said he had felt irritable and "headachy"
|
|
during and immediately after the interpretation was given. That
|
|
evening he returned to a gay pornographic movie theatre were there
|
|
was much sexual activity among the patrons. Before the analysis
|
|
this was one of his regular haunts but he had stopped patronizing
|
|
the theatre many months before. The patient allowed several men to
|
|
perform fellatio on him. He felt angry and painfully excited as he
|
|
thought the fallators really appreciated what he had. In response
|
|
to what he felt was the analysts inadequately appreciative response
|
|
the patient had desperately turned to a more concrete indication
|
|
that someone could appreciate his accomplishments. Another patient
|
|
experienced every weekend as "like being sent away to live in the
|
|
Sahara in a desert" and the return to the analysis as "like coming
|
|
back to the oasis."
|
|
When their feelings are not interrupted these patients like
|
|
these experience the analyst in characteristic ways that Kohut
|
|
described with oversimplifying systemticity. Some patients
|
|
idealized the analyst seeing in him the embodiment of strength and
|
|
good and feeling alive and whole in his presence. Others find
|
|
relief in the sense of being in a unity with their analyst, or
|
|
being like him or being appreciated by him. Interruptions in these
|
|
states of mind commonly bring with them inordinate distress or
|
|
symptoms which could be reasonably understood as experiences of a
|
|
fragmented or devitalized self or attempts to avoid those
|
|
experiences.
|
|
From these clinical experiences Kohut posited that there were
|
|
a group of people for whom the maintenance of a satisfactory self
|
|
experience was centrally important because it was so problematic.
|
|
The analyses of these patients was characterized by the use of the
|
|
analyst to maintain the a cohesive and vital self by using the
|
|
image of the analyst as part of the self or as a support for the
|
|
self. Any interruption in the capacity to use the analyst in this
|
|
manner lead to the reemergence of problems in this area. The
|
|
situation within the analysis was equated with postulated normal
|
|
developmental states in which the caretaker ordinarily performs the
|
|
functions for the self. These functions Kohut called selfobject
|
|
functions and he believed his patients to be suffering from
|
|
disorders of the self resultant on traumatic failures of early
|
|
selfobject functions. As in normal development small, empathically
|
|
supported, failures in the selfobject function allow patients to
|
|
identify with the image of the way the analyst should have
|
|
functioned and to make those functions more their own. However
|
|
mental health does not consist in giving up self objects. Kohut
|
|
asserted that selfobject functions normally continue across the
|
|
course of life and that it is their qualities, not their existence,
|
|
that is altered with maturity. (Having made this assertion Kohut
|
|
never elaborated or demonstrated it. Recently Bertram Cohler and
|
|
myself have undertaken the task of exploring the empirical evidence
|
|
for Kohut's position.)
|
|
Kohut's findings, and the findings of many of those who have
|
|
examined the psychology of the self from other viewpoints, have
|
|
been questioned in too apparently distinct ways, whose
|
|
interconnection I will show you in a moment.
|
|
The first objection is that Kohut's theories serve to avoid
|
|
painful psychological truths. Many of the phenomena Kohut observed
|
|
had been observed previously and classified as defensive
|
|
operations. For example, idealizations of the analyst were commonly
|
|
understood as ways both to avoid knowing of the unconscious
|
|
demeaning of the analyst and to arrange for disappointments when
|
|
the analyst fails to live up to the idealization as he inevitably
|
|
must. The idea that the patient "needs" the analyst to function in
|
|
some certain fashion lest his core being be seriously damaged could
|
|
be understood as a fantasied misunderstanding designed to
|
|
rationalize wishes whose non-fulfillment may be extremely
|
|
frustrating but not inherently, must less psychologically fatally,
|
|
damaging.
|
|
The second set of objections has to do with the theory of the
|
|
self. Kohut never clearly defines his central concept of the self.
|
|
Essentially he says that everyone knows from experience what the
|
|
self is and leaves it at that. After studying the many discussions
|
|
of the meaning of the "self" in the psychoanalytic literature one
|
|
is reminded of the Buddha's comments on the self. He said that
|
|
those who believe in the self are like "a man who says that he is
|
|
in love with the most beautiful woman in the land, but is unable
|
|
to specify her name, her family or her appearance" (Digha Nikaya
|
|
I 193, quoted in Carrithers (1983).) The essential theoretical
|
|
difficulty was clarified by Meissner who pointed out that the term
|
|
self as habitually used by Kohut and most other writers whose work
|
|
places the self at the center of psychological life, is
|
|
consistently used to refer to both a psychological representation
|
|
and also a psychological agent. Although more systematic
|
|
researchers, for example Hartman, limit the concept of self to a
|
|
psychological representation of the person, they also give the self
|
|
a markedly subsidiary role in psychology. Meissner's argument is
|
|
quite similar to Schafer's later discussions of internalization in
|
|
which Schafer observed that the elaborate analytic theories of
|
|
internalization were in fact nothing more then the translation into
|
|
psychoanalytic jargon of unconscious fantasies and did not, in his
|
|
view represent, represent actual psychological mechanism and in
|
|
fact obscured, what actually happens when we have experience that
|
|
had been described as the taking in of another person or aspects
|
|
of that person.
|
|
The two problems with self psychology, its use as a defense
|
|
against painful insight and its confusion of agent and image, are
|
|
related. Notice that if the self is "only" a psychological
|
|
representation it would follow that the patient's idea that had
|
|
will be dysfunctional as a direct result of some impairment in this
|
|
representation seems mistaken - or at least so it seemed to many
|
|
thoughtful psychoanalysts. Only the impairment of some mental
|
|
agency could really result in dysfunction. It was if the patient
|
|
complained that his car did not function because part of a picture
|
|
of the vehicle had been obliterated. The idea that the patient is
|
|
in error in this regard supports the clinical stance that the
|
|
patient's fears in these matters are not an accurate assessment of
|
|
the situation but rather fantasies motivated by their unconscious
|
|
desires to hide deeper psychological realities.
|
|
Now of course we all know that there are "mere"
|
|
representations that are very good for actually doing things and
|
|
whose faultiness causes no end of problems. These representations
|
|
are called programs.
|
|
Now, I suspect that once stated the notion that the self is
|
|
a program which like other programs is capable of change by
|
|
altering its representation and at the same time is an active agent
|
|
is neither a surprising or remarkable idea. However, when one
|
|
notices that fifty years or so of both clinical and theoretic
|
|
psychoanalytic thinking about the self has been profoundly
|
|
influenced by the idea that the existence of such an object is a
|
|
logical impossibility the point seems more worth making. The other
|
|
advantage of making this point is that it invites us to use what
|
|
we know about programs to think about the self and suggests the
|
|
systematic characterization of the self as a program.
|
|
Let us begin the selfobject function whose enemies are want
|
|
to equate it with some form of mysticism. We know, of course, that
|
|
programs have meaning and function only within computational
|
|
environments. An inappropriate computational environment can alter
|
|
the meaning and operation of the program or render it altogether
|
|
meaningless. For example a routine that calls a global variable
|
|
gives a different value depending on the value of that variable;
|
|
a program written in C for which one has no compiler is totally
|
|
useless. The use of the term "computation environment" in computer
|
|
science is relative to the process being discussed and only has
|
|
meaning once one specifies what program is being referred to. An
|
|
expression only has meaning within an environment. Having bound a
|
|
global variable that value then becomes part of the computational
|
|
environment of the programs running within that context. Of course
|
|
from a different viewpoint the program that sets up the environment
|
|
for our first program itself has an environment. Thus ordinarily
|
|
we expect that program will "need" appropriate environments in the
|
|
same way that self psychology predicts that people need
|
|
selfobjects.
|
|
What one chooses to call program and what environment
|
|
obviously effects the picture of the situation that emerges and is
|
|
a function of the interest of the investigator. Similarly the
|
|
boundaries of the self depend on the point of view we adopt based
|
|
on the focus of our interests. It is only important to notice that
|
|
the choice is ours, not intrinsic to the system under study and
|
|
that it is important not to become confused about the principles
|
|
governing the entities we have defined. A few decades ago von
|
|
Bertalanfy made a minor industry of pointing out the inappropriate
|
|
application of conservation principles to "open" systems that were
|
|
mistakenly treated as having no energy flux across their
|
|
boundaries.
|
|
The mechanics of the selfobject or the environment is
|
|
naturally important but by no means definitive in terms of its
|
|
function. In one since it is obviously of considerable importance
|
|
whether a subroutine that is called is available in RAM, is
|
|
currently located on a easily accessed storage device or is located
|
|
on a tape that the machines operator must fetch and mount before
|
|
it can be used. In another sense these mechanical considerations
|
|
are of minor importance in our understanding of the program.
|
|
Likewise whether the capacity to be soothed is a readily available
|
|
group of psychological functions represented within the cranium,
|
|
the activity of a caretaker who is but a cry away or requires some
|
|
elaborate undertaking - say a few years of psychoanalysis - can be
|
|
regarded as involving no essential difference in this function.
|
|
Although he never would have put it in this way this is an
|
|
essential aspect of what Kohut was trying to point to in the idea
|
|
of the selfobject - something that functions as an essential aspect
|
|
of the self or of the support of the self but which because of the
|
|
mechanics of its availability is at times less efficiently
|
|
accessible than other aspects of the self that we are more
|
|
accustomed to including in our idea of the self. This computational
|
|
relative inaccessablity commonly is associated with the need for
|
|
particular perceptual inputs and computational assistance.
|
|
For instance the phenomenon of "social referencing" has been
|
|
studied extensively from a social psychological point of view.
|
|
Starting at about age seven months given a novel situation or a
|
|
situation with elements that suggest danger babies look to
|
|
caregivers for cues about whether to proceed and base their actions
|
|
on the caretaker's response. Toddlers as they move away from mother
|
|
in a play ground frequently turn around, checking mother's
|
|
expression before proceeding further. In the toddlers experience
|
|
the decision does not take its basis in the issue of whether
|
|
mother, as a person approves or disapproves of the action, rather
|
|
the mother's approving response registers as an impersonal "It is
|
|
okay." The toddler has not called the person "mother" in this
|
|
situation but has rather expanding his computational resources
|
|
which happen at the moment to be located in the being we would
|
|
refer to as his mother. The child needs loves nor hates the mother
|
|
in this context but does need her to function. If she is
|
|
functioning well like any computational resource he remains unaware
|
|
of her presence. It is only her failure of availability that makes
|
|
her of interest, just as we are generally unaware of our memories
|
|
except when we have difficulty recollecting something we need to
|
|
continue our thinking.
|
|
Those of you familiar with Marvin Minsky's work recently
|
|
summarized in The Society of Mind will recognize in these ideas a
|
|
particular application of the multi-hierarchy computational model
|
|
that can be used to explore processing within many levels of human
|
|
function from neurons to societal organizations. The issue of a
|
|
non-pejorative attitude to what we call mysticism comes to mind
|
|
here. Much of what is referred to as mystical might well be
|
|
considered as attempts to comprehend hierarchically higher
|
|
computational structures within the computational world of lower
|
|
order entities.
|
|
The self as a program does two important things that are the
|
|
subject of our constant attention in our analytic work. The program
|
|
monitors its own operation and ordinarily modifies itself in
|
|
response to such monitoring. The type of programs we are familiar
|
|
with in daily work with computers generally have facilities to
|
|
monitor and modify their own execution to a limited extent. Error
|
|
trapping of one type or other is virtually universally employed so
|
|
that unexpected or undesirable situations do not result in the
|
|
continuation of "business as usual" but instead lead to some kind
|
|
of branching in the process. In an "error" situation the new
|
|
execution often takes the form of enlarging the computational
|
|
environment to include the operator who is asked how to proceed or
|
|
to correct some situation that impedes the computation or to
|
|
authorize the use of additional computational resources. For
|
|
example if the execution of a program requires more than a certain
|
|
amount of time the systems operator may be asked whether to
|
|
continue or abort the execution.
|
|
Similarly, but much more extensively, the self is engaged in
|
|
a constant process of monitoring its own function and functional
|
|
needs, arranging for them to be met or attempting to compensate for
|
|
their not being met. We have already implicitly discussed the
|
|
ongoing monitoring of computational resources and the recognition
|
|
of the need to evoke devices such as the perception of other people
|
|
to serve as selfobjects. The detailed study of the nature,
|
|
functions and situations in which these additional computational
|
|
devices are called or where calls to such devices is avoided
|
|
constitutes a major area of psychoanalytic investigation that
|
|
encompasses much of object relations theory, including self
|
|
psychology, attachment theory, the concept of the transitional
|
|
object and the role of cultural experience.
|
|
In the von Neumann architecture computer design was dominated
|
|
by the wish to avoid programming errors. This was accomplished by
|
|
carefully separating data, programs and processing functions and
|
|
forcing sequential processing so that except in terms of the
|
|
overall duration of computation the outcome of a computation was
|
|
unaffected by the time required for each computational step.
|
|
Furthermore building this basic architecture requires the
|
|
anticipation at least the basic architecture of the system from
|
|
its beginning. It cannot result of the evolutionary piecing
|
|
together of elements designed for other functions as the brain must
|
|
have evolved.
|
|
The von Neuman architecture is so excellent an environment for
|
|
humans to design programs for that it dominated computer design for
|
|
almost four decades. However as von Neumann noted from early on
|
|
this architecture is a poor model for brain functioning. The
|
|
microsecond firing times of neurons are much to slow to allow
|
|
brains to do the things they do all the time with a von Neumann
|
|
machines. Furthermore brains are the result of a bioevolutionary
|
|
process, not a unitary design and its programmer is not an
|
|
individual who sets out to explicitly specify processes but an
|
|
environment with many other things on its mind than programming
|
|
brains. Of course we know from direct study of brains that they
|
|
operate through massively parallel processing.
|
|
Fortunately for those of us interested in brains and their
|
|
productions it has become clear that the technological limitations
|
|
inherent in the von Neumann architecture make it essential that
|
|
other architectures be explored in depth to make more capable
|
|
computers. The last five years has seen an explosion of
|
|
publications about parallel processing architecture and we will be
|
|
among the beneficiaries of the resultant intellectual advances.
|
|
But, of course, the problems that von Neumann sought to avoid
|
|
in computer design are precisely the problems that emerge in
|
|
parallel processing. It is simply much more difficult to predict
|
|
what is going to happen when things do not go on sequentially, when
|
|
the distinction between memory and processing is abandoned and
|
|
simple hierarchies of bindings are abandoned. Now rather then
|
|
building the absence of these difficulties into the architecture
|
|
of the system it becomes necessary to discover ways to overcome
|
|
them. A much more elaborate system of error trapping and control
|
|
becomes essential.
|
|
Parallel systems are highly vulnerable to internal conflicts
|
|
and instabilities. Attempts to remove these features from the
|
|
system usually entail the loss of precisely what has been gained
|
|
through parallelism. To give an very elementary but quite everyday
|
|
example, when a database can be updated through several different
|
|
inputs there is considerable danger that attempting simultaneous
|
|
updating of a record will result in loss of data or undesirable
|
|
results. Suppose I am making a deposit in my savings account at the
|
|
same time that interest is being calculated and recorded in the
|
|
same record. In many database systems the entire record is
|
|
retrieved updated and stored again. So in this instance the
|
|
original record is retrieved by both the deposit and the interest
|
|
function. Each, independently updates the record and then writes
|
|
it to the storage device. Either the deposit or the interest
|
|
payment, whichever is stored last, will be recorded but not both.
|
|
A simple solution that is used in many database systems is to make
|
|
the record available to only one potential input at a time by
|
|
locking it to other users while it is in the hands of a potential
|
|
inputter. In essence one suspends parallel processing and goes to
|
|
sequential processing in the face of such potential errors. This
|
|
is an awful solution for simple database management, although as
|
|
anyone who has worked with such a system knows it can be thoroughly
|
|
annoying. But such a general solution for a massively parallel
|
|
system would slow the whole thing to a snails pace. Thus special
|
|
mechanism for recognizing, protecting against and resolving
|
|
conflicts are expected to be a central aspect of massively parallel
|
|
system.
|
|
But notice how close we have gotten to the ordinary stuff of
|
|
psychoanalytic clinical work. A lot of what we do in analysis has
|
|
to do with successes and failures to resolve conflicts between
|
|
computational results achieved through parallel processing of
|
|
situations. To give a much oversimplified instance, a young man
|
|
who might displace a supervisor by putting forward his own ideas
|
|
expresses them but muddles their presentation. Analysis reveals
|
|
that his actions result from two parallel, conflicting computations
|
|
and an attempt to resolve that conflict. On the one hand are a
|
|
variety of factors including his wish for greater prestige and
|
|
material wealth that in turn reflect a long sequence of
|
|
developmental processes and on the other his assumption (which is
|
|
outside of awareness) that he will be harmed in various ways if he
|
|
pursues these wishes results in a state of conflict. This conflict
|
|
and potential conflicts are dealt with variously by some higher
|
|
order resolutions or through the isolation of the processes from
|
|
one another by a variety of means. The resulting action,
|
|
unfortunately called a "compromise formation" in psychoanalytic
|
|
jargon is an attempt to synthesize the results of these two groups
|
|
of computations.
|
|
An even greater danger to the system than partially
|
|
contradictory computational results is its own instability.
|
|
Computational process may become chaotic, disorganized or pass
|
|
through a catastrophe as we recognize in depth when we study them
|
|
in terms of dynamical systems. It is reasonable to expect that a
|
|
computational system can only function in anything like a
|
|
satisfactory manner if such situations is rigorously limited to
|
|
lower levels of function and if the system has extensive safeguards
|
|
against higher level catastrophes or chaos.
|
|
Again this is precisely what we find clinically. The most
|
|
central concerns in disorders of the self frequently are concerns
|
|
about discontinuous and disorderly change. A typical error trapping
|
|
procedure in the area where catastrophic change seems a danger is
|
|
to avoid all change whatsoever and to attempt to isolate the
|
|
computational processes from outside influences that might result
|
|
in change. Recently I described how the process of working through
|
|
in psychoanalysis, the repeated reexamination if slightly different
|
|
versions of paradigmatic situations within an analysis, could
|
|
usefully be regarded as the reestablishment of a Boltzman
|
|
algorithm-like psychological function by which existing "solutions"
|
|
are repeatedly and automatically reexamined both to achieve greater
|
|
optimality and to integrate data that may have been unavailable at
|
|
the time they were formed. I said that much psychopathology could
|
|
be usefully characterized as the interruption of this ordinary
|
|
process in the face of a perceived threat of disruption or
|
|
disorganization and that what we often think of as the curative
|
|
factor of working through is just the resumption of normal
|
|
psychological function.
|
|
This brings us to the third way in which the self differs from
|
|
the programs we are most familiar with from the study of computers.
|
|
The self is self developing. Here my opinions are somewhat
|
|
different from many of my psychoanalytic colleagues, so let me
|
|
spell them out briefly. As she attempted to explore the concepts
|
|
of normality and pathology in childhood, Anna Freud discovered that
|
|
the presence or absence of symptoms per se was not an adequate
|
|
guide in assessing children. She concluded that childhood was
|
|
normatively a period of change and development and these were its
|
|
primary tasks. The failure of such for such development to be
|
|
ongoing was the essence of psychological disturbance in childhood.
|
|
For Anna Freud, who had a clear picture of what psychological
|
|
health was like in adulthood, the task of childhood was move toward
|
|
such mature functioning and she posited a drive to "the completion
|
|
of development."
|
|
Three groups of observation impressed me into extending her
|
|
notion. First the past quarter century has yielded a massive
|
|
demonstration that human development normal continues across the
|
|
entire life course - that the idea of a definite mature
|
|
developmental state whether occurring with the resolution of the
|
|
Oedipus complex or the end of late adolescence or whenever else is
|
|
mistaken. Second there seem to be quite diverse ways to be
|
|
psychologically healthy which becomes readily apparent if we avoid
|
|
employing a priori notions of the meaning of health. Finally the
|
|
work begun by Marsh to the effect that programs can be written not
|
|
with specific goals in mind but rather that proceed to explore and
|
|
develop in area that are vaguely defined by such criteria as
|
|
"interestingness" corresponded so well to the observations of
|
|
workers like Piaget who found that exploration and development were
|
|
self motivating that it seemed likely that the human mind is such
|
|
a system. It thus seems reasonable to posit that an ongoing
|
|
function of the self is its own reorganization and development.
|
|
Indeed it was this point that first led to my interest in a
|
|
computation model of the self because the question of how the self
|
|
could be both agent and representation and in particular how it
|
|
could be an agent acting on itself as a representation has a long
|
|
standing concrete instaniation in Lisp. Lisp, one of the two oldest
|
|
high level programming languages in common use, was specifically
|
|
designed to manipulate list of symbols. Of course lisp programs are
|
|
themselves list of symbols so that lisp programs can be operated
|
|
on my lisp programs including the program itself. The species that
|
|
seemed so internally contradictory that analysts denied there
|
|
existence have in fact been around for a long time.
|
|
Now, of course such programs are not without very serious
|
|
problems - in particular they too can be much less stable and far
|
|
less predictable than those programs were program and data are kept
|
|
strictly separate. As with parallel processing one way to protect
|
|
from the dangers inherent in such a structure is to carefully limit
|
|
in advance the changes the program can make in itself. Another
|
|
possibility is to monitor the development of the program and
|
|
introduce error trapping and correction as untoward consequences
|
|
of the rewriting occur. A combination of the two approaches would
|
|
seem to be necessary. In a sequential system for example a fatal
|
|
error occurs if a real interminable loop is introduced into a
|
|
program. Here, however, parallelism and conflict can be of
|
|
considerable help. Freud's idea of a tripartite model of mind
|
|
essentially involves the parallel processing of data, the
|
|
consequent development and resolution of conflict so that a variety
|
|
of needs can be met through these various modes of processing. In
|
|
particular aspects of the mind can monitor the ongoing process of
|
|
the development of the self - interrupting and altering it when it
|
|
comes parlously close to instability or stagnation.
|
|
The hierarchical level at which these process can proceed are
|
|
various and new levels in the hierarchy seem to develop with
|
|
greater maturity. In particular greater capacities for abstraction
|
|
both from data and process appear to be a normal part of human
|
|
development. With these capacity comes increased abilities for
|
|
metacognition. Piaget's observation of the progressive decentering
|
|
of cognition with the related capacity, for example to think about
|
|
thinking, represents such an elaboration of abstraction
|
|
hierarchies.
|
|
Among the many objections that could be raised to my
|
|
discussion is the importance I lay on introspection and
|
|
subjectivity as a source of information about psychological
|
|
processes. From a computational viewpoint consciousness is an odd,
|
|
unnecessary, or at least peculiar phenomenon, while from the point
|
|
of view of classical psychoanalysis precisely what is most
|
|
interesting about people is barred from the conscious awareness.
|
|
Thus subjective reports about experience should be relatively
|
|
uninteresting to both groups. However, following Vygotsky and
|
|
Basch, I take a different point of view about consciousness.
|
|
Consciousness is a state that we employ when automatic functioning
|
|
becomes problematic. For example we only become aware of walking
|
|
when we stumble or when we are learning how to do it and only
|
|
attend to it in detail if something impedes are ability to walk.
|
|
It is thus precisely in areas of difficulty that we expect
|
|
awareness to appear. So it is the areas of difficulty that we
|
|
should find well represented in consciousness. Freud's idea of
|
|
bringing the unconscious into awareness then is nothing more then
|
|
the extension of this normal process into areas in which it is not
|
|
employed. In particular the mechanism of repression reflects a
|
|
special procedure to keep ideas separate from each other by not
|
|
bringing them into awareness. But more generally we can use
|
|
subjective experience as at least a preliminary guide to the
|
|
computational difficulty.
|
|
I am well aware of having painted the picture of the
|
|
computational self with extremely broad strokes and having done
|
|
violence to many subtle and important issues in the process. At the
|
|
same time I am impressed that psychoanalysts having discovered that
|
|
the Freudian and ego-psychological paradigms are inadequate have
|
|
largely abandoned the attempt to develop broad theories that
|
|
encompass the particular data of the psychoanalytic field, choosing
|
|
instead to focus on smaller more tractable problems and maintaining
|
|
an unavowed theoretical agnosticism.
|
|
An exception to this abandonment of theory lies in the work
|
|
of the self psychologists. However their conceptualizations,
|
|
especially those of Kohut, while evocative remain vague. I think
|
|
it is clear that the computational properties of the mind must find
|
|
representation in personal psychology. I have suggested one
|
|
possibility for how this may occur using the computational self as
|
|
the central organizer for my thinking and attempting to show how
|
|
ideas from computer science may yield models that are congruent
|
|
with our clinical experience. Just as I believe development is the
|
|
central activity of the self so to I believe development should be
|
|
the central goal of our intellectual activities. Thus if this
|
|
paper, despite its flaws does nothing more then stimulate some of
|
|
you to think along these lines and to help me do so more cogently
|
|
I will be satisfied.</p></xml> |
