In this paper, as in one that I delivered at the Third International Conference
on the Theory of Positive Disintegration in Miami (1980), I would like to
reaffirm that the Positive Disintegration Theory speaks to a very real and
critical problem of our times — the problem of how we might find objective
values. This you know already — through exploring multilevelness, particularly
at higher levels of development.
But the new
strings that have been added to the harp to give it a richer melody are a new
appreciation from a constructionist view that objectivity and subjectivity are
not polar concepts. Rather, objectivity is to be found in authentic subjectivity.
I will propose "intuition" as a concept capable of bridging the gap between
the Positive Disintegration Theory and other psychologies, and I will offer a
brief perusal of levels of intuition — something which, as far as I know, has
not previously been done. Another (and you will be happy to know) final
newly-added string will be an appreciation of how constructing a hierarchy of
values is essentially a hermeneutical task. In this area the phenomenologists
contribute to the theory the concept of "objective hermeneutics". Those are
the main points I have to make, and thus they summarize this paper. Those are
the new strings I have added to my harp. Thus this may be given, in the
classical tradition of Izaak Walton, the title: "The Compleat Lyre".
Matters of
value were always close to the heart of Kazimierz D¹browski. Not only is
Positive Disintegration a value-laden theory, but Dr. D¹browski, was himself a
man of principle and concerned deeply for the directions society was taking. It
is value in this second sense — not just as a preference for one thing over
another, as one might choose a Van Gogh over a Rembrandt — but value in the
moral imperative sense of oughtness, moral value, that this paper primarily
addresses. The quest, as was D¹browski's, is for objective moral values. My
point is that the Theory of Positive Disintegration has something special to
contribute to this quest. Objective values (including moral values) are to be
found not through cognitive functioning alone as cognitive developmentalism
maintains, nor through feeling by itself as emotivism purports, but in a more
holistic, systemic, multilevel approach inherent in the Theory of Positive
Disintegration.
Philippa
Foot laments the fact that moral philosophers have a penchant for leaving gaps
in their philosophical understanding of the values of different societies. She
attributes this to "conventions that forbid the philosopher to fill
chapters with descriptive material about human nature and human life. It isn't
supposed to be part of his work to think in a somewhat discursive way that is
suitable to reflections about the human heart, and the life of men in society"
(Foot 1982, p. 165). It is one of the goals of this essay to, in some small way,
help fill one of these gaps. It is my conviction that the Positive
Disintegration Theory still carries the stamp that Kazimierz D¹browski placed
so firmly upon it — a deep reflection about "the human heart, and the
life of men in society".
Value
Hierarchies in the Theory of Positive Disintegration
In my recent research into value hierarchies I have been using the Rokeach Value
Survey, not to measure the values of my subjects but to examine the process of
forming a hierarchy of values. I asked them not just to rank order their values
as the RVS requests, but to write down their comments on the process of frank
ordering as they attempted to do it. Interesting things happened. The questions,
confusions and challenges they raised not only throw doubt on the RVS as an
instrument for measuring an individual's values, but (more importantly and more
relevant to our topic here) their remarks bring out the sharp contrast between
merely rank-ordering a list of values and forming an actual hierarchy of values.
In a nutshell, values cannot be strung out like washing on a clothes line in
some serial fashion; instead they form a hierarchy (or heterarchy) which means
they are in constant relationship with each other, constant tension with each
other. The best way I can put it is to say that values are conscious of each
other. It is a systemic relationship; a value can be considered only in its
relationship to other values.
Thus, in the
remainder of this paper, I am not going to talk about specific values or
specific moral rules or where certain values "ought" to be in one's
hierarchy, but I am going to talk about values as a system, and address the
question of whether one can lay claim to hierarchy of values as something
objective. It is a question central to the Theory of Disintegration, a question
D¹browski himself pursued and one to which we can perhaps add something today.
We will concentrate on the higher levels of development because that is where
objectivity is best constructed. That is because, in the D¹browskian paradigm,
higher levels are characterized by superior subject-object relationships, and
authenticity related to the personality ideal. But we will not neglect the lower
levels — the common man and woman — because objectivity to some degree is
attainable by the less-than-eminent person in what I will be calling a "hermeneutic
dialogue".
Authentic
Subjectivity
Our approach to the question of moral objectivity springs from a deceptively
simple statement of Bernard Lonergan: "Objectivity is the fruit of
authentic subjectivity" (Lonergan 1974, p. 214). But notice that Lonergan
says: Objectivity is not the fruit of just any such objectivity, but of
authentic subjectivity, and, as I shall propose, is related to the level of
authenticity within the individual. What immediately needs to be done, then,
with Lonergan's statement, is to explore the meaning or meanings of "authentic
subjectivity". And here is the key D¹browski offers with the novel core
paradigm of the Theory of Positive Disintegration — the concept of
multilevelness — that not only are there levels of development in the
traditional chronological sense but there are qualitative levels within concepts
and psychological functions. That there are levels within the concept of "authentic
subjectivity" will be offered as a suitable approach to the
objectivity question.
"Authenticity"
in this sense becomes a dynamic concept. Since we are in the realm of morality,
mere speculative judgments of value are not enough; it is only in performance,
in the pursuit of moral good, that authenticity is found. It is to his credit
that D¹browski, in his wisdom, insisted not only on a hierarchy of values, but
on a hierarchy of aims — on values carried over through intention into action.
With decision and choice, one makes oneself an authentic or unauthentic subject.
To explore
the levels of authentic subjectivity we will return to an old, but recently
revitalized word in the psychology of morals — "intuition". We will
explore intuition as a holistic, multilevel term for understanding the
possibility of attaining moral objectivity through "authentic subjectivity".
To me intuition, though not a much developed word in the Positive Disintegration
Theory, deserves our attention. It can be the bridge between the Positive
Disintegration Theory and present-day moral psychology carrying the holism of
Dabrowski's theory into that splintered territory of moral philosophy and the
psychology of values.
Intuition
in Lawrence Kohlberg’s Theory
I have mentioned intuition as an old but renewed term in moral philosophy and
psychology. One person responsible for this resurrection is no less than
Lawrence Kohlberg. Under the influence of his critics (notably Carol Gilligan)
Kohlberg in 1984 begrudgingly acknowledged the existence of "B type" persons
who gave Stage 5 "right answers" to his dilemmas, as the result of an
intuitive understanding of the core reasons for their choices. "A type B
person is someone who intuitively or in his or her "heart" or, "conscience"
perceives the central values and obligations… articulated rationally by Stage
5 and uses these intuitions to generate a judgment of responsibility …implied
then is the "Platonic", "Kantian" or "intuitionist" view that the conscience can
dimly intuit rationally principled justice and act accordingly" (Kohlberg
1984a, p. 63).
One who has
only a unilevel view of intuition is in danger of giving it credit only for
dimly intuiting. If we have a multilevel view we perhaps can credit conscience
with the capacity for "brighter", more objective intuitions. Interestingly,
we need go no further than Kohlberg himself to find someone exploring (without
using the terminology) the many levels of intuition in pursuit of moral
objectivity, and finding that objectivity at higher levels of intuition.
Kohlberg's excursion into Stage 7 in 1970 and his recent updatings of his
thought (Kohlberg 1984b) develop this. Fifteen years ago Kohlberg called Stage 7
a metaphor and not really a stage at all. More recently (Kohlberg 1984b) he
elevated it to a soft stage.
Whatever its
status, it was meant "to take away from Stage 6 the excessive demands
placed on it, the demand that it provide the answer to the problems of the
meaning of life" (Kohlberg 1970, p. 3). Kohlberg found in Stage 7 "an
emotionally powerful intuitive grasp of reality that a metaphysics can only in a
limited way express conceptually" (Kohlberg 1981, p. 369). The beginnings
of a multilevel approach were expressed by Kohlberg and Candee (Kohlberg 1984a,
p. 64) when they said that type B judgments rest on a content-related and
teleolgical intuition of a natural hierarchy among nine universal moral norms
and that this hierarchy is "dimly perceived at the type B perspective from
Stage 2 onward, but it is only at Stage 5 that the hierarchies become consensual...".
Going even further, Kohlberg described Stage 7 as taking the postconventional
person beyond the merely rational into the experiential, the religious, and even
the mystical where a whole person, not just a cognitive person, is intuitively
active in finding a will to meaning and a will to be moral, despite apparent
meaninglessness and the immorality of the world as is exists. Kohlberg has said
"Mystical experiences that are religiously significant are those in which
the oneness of being is disclosed and the subject-object duality is overcome"
(Kohlberg 1981, p. 369).
Kohlberg's
mature view led him to an appreciation of levels of development that encompassed
much more than cognitivism, achieving at higher levels of religious experience
an intuitive grasp of objective morality in an experience of life that
transcended subject-object dichotomies. In a word, Kohlberg, before his death,
moved from a Piaget style concern with cognitive stages of moral reasoning in
children and adolescents to a more holistic life span approach to moral choosing
that realized the importance of the religious dimension at least at the higher
levels. Thus his theory, now outgrown mere cognitivism, is in need of a more
holistic framework such as the Theory of Positive Disintegration to give it a
coherent, multilevel appreciation of what goes on in moral choosing throughout
the life span. But this is another and major study, and I have addressed it at
length in another place (Hague 1987). Another of Kohlberg's mature statements
relevant to our topic is the result of his relationship with Habermas. At the
end of a massive chapter, entitled, "The Current Formulation of the Theory"
in his "Psychology of Moral Development" (1948b) Kohlberg says: "We believe
in line with Weber (1949), Habermas (1983) and others that objectivity is a
'moment' of scientific inquiry; that the essence or 'truth' value of
objectivity does not reside in some reified, permanent or factual quality
inherent in the object of inquiry, but is rather to be found in and understood
as a process of understanding which is the changing relationship between the
investigator and what he or she observes. We believe that it is this theoretical
and methodological orientation aptly expressed by Habermas's notion of 'objective
hermeneutics' that characterizes our work".
It is not
surprising to find the presence of Habermas in this issue, given the widespread
influence he has had, but it is more interesting and exciting to explore where
the ideas of Kohlberg and Habermas in the context of multilevelness might take
us. We will return to this.
Scholars
have traditionally recoiled from the word "subjective" when talking of
morals because it envisioned a rampant individualism, a rule by personal urge,
or at best a rule by the great sweaty masses of the majority. But by looking at
subjectivity at various levels of authenticity, we can, I think, propose a
subjective approach to moral judgment-making that enriches the concept of
objective hermeneutics. It also enriches that word "intuition" by giving it
levels of meaning, permitting higher, more authentic levels of intuition.
Clearly I am
building a case for moral judgment-making that pictures it not just as a series
of cognitive stages stretching through childhood and adolescence, but one that
usually finds its greater complexities and proliferation of levels in adult life,
and its highest refinements in addressing the transcendent, religious,
meaning-laden moral questions that permeate the higher levels of development. It
takes time to develop from being a "subject" in the immediate world of
unreflected sensations to becoming an authentic person in the adult world of
meaning. It is a journey, not an arrival. There is no static state of perfection.
Authenticity means a continuous asking questions of self and life, moving from
immediate experience to understanding, and beyond understanding to reflection,
and through reflection to judgment and, ultimately to questions of
worthwhileness — questions of value. It is all process towards higher levels
and entrance into that transcendent domain of ultimate meaning and metaethical
questions of value where subject-object dualities disappear. Authenticity, at
core, is a process and a function of what questions we ask of life.
Multilevelness
in Kazimierz D¹browski’s Theory
D¹browski has mapped out some qualitative criteria of levels of concepts. These
deserve demonstration here if we are to share understanding of levels of
intuition.
In general,
Dabrowski's levels are distinguished by a movement from the automatic, and
unreflected to the more voluntary and reflected upon. Each new structure is
qualitatively different from the preceding. It is more complex, yet more
integrated. Forces of self-direction and self-determination emerge, permitting
transcendence of the biological life cycle. The movement is from inner
experience determined by behaviour and external forces to behaviour determined
by inner experience. Self direction, autonomy, authenticity are the forces that
give each new level a higher qualitative component.
Just as the
presence of characteristic dynamism distinguished Dabrowski's levels, so the
active presence of these dynamisms in human activity indicates the level of that
behaviour. Perhaps a glimpse at some of the dynamism most relevant to objective
judgment-making would best serve our purposes here.
The
Higher Level Dynamism of Objectivity
Besides the authenticity dynamism which D¹browski saw as operative at higher
levels of development, he described another high level dynamism particularly
relevant to our discussion of moral objectivity. It is the dynamism he called
"subject-object in oneself"— an ability he ascribed to higher level
persons to see others as subjects and oneself as an object. To my mind it is
something much more than identification or role-taking which has long been
explored in the psychology of morals. This dynamism includes not only the
ability to stand in another person's shoes, sharing their subjective experience,
but to stand outside oneself, to distanciate from oneself, to assume the
unaccustomed role of seeing oneself as an object and to reflect upon that. The
self-objectification will often be expressed in words or other affect-laden
images allowing room for distanciation and the objectivity that comes from
gaining perspective. Van Gogh's self portrait is as much a personal
distanciation as is Hamlet's soliloquy. I have slipped the word "distanciation" in here, and you may be surprised by it as I was not too
long ago. But it is a good word from epistemology and ties in nicely with what D¹browski
was trying to say with his dynamism of subject-object in oneself. We are all
experts at being subjects; the world of our own experience is immediate to us.
Correspondingly, if we are not careful (full of care) we can easily become, even
from childhood, experts at seeing others as objects. As Buber has pointed out, a
humanizing relationship is not possible when, buried in one’s own subjectivity,
one treats others as objects. D¹browski challenges us to enter into the life
space of the other and experience the world from their point of view, and,
conversely, to step outside our own easy subjectivity, to view ourselves
objectively.
Like an
artist too close to his painting for too long a time, we need distance to give
perspective. So we must psychologically constantly "step back". This is
distanciation. It is, for example, the kind of distance from a concern that a
client gets from talking with a counsellor. It is the kind of distance from
one's own development that a person gets by putting it in words on paper in a
personal journal. D¹browski and
Piechowski (D¹browski & Piechowski 1977, p. 150) report an illustrative
passage from a reflection of one of their subjects: "Thinking appears to me to
be one-sided; it has lost somewhere its logical certainty. I am more uncertain
and more hesitant, yet at the same time I find myself richer in my thoughts and
feelings. Perhaps loss of certainty in thinking and its closer interdependence
with feelings are really tied together with a greater complexity and depth of
thinking as a way of knowing".
The image is
affect-laden. Most often, as in this illustration, it is in words; sometimes it
is in art or in the beauty of life lived reflectively. By imaging self in
relationship to others, one gains distance, perspective and ultimately objective
self understanding. On the other hand, by trying to interpret the affect-laden
images of other words and actions we engage in hermeneutics, and one gains to
some extent the other's subjectivity. We will return to this hermeneutical
process toward the end of this paper when we address the practicalities of
creating and communicating objective values. For now the concept of intuition
will carry us along our way.
Intuition
as a Multilevel Concept
Looking at intuition from a multilevel perspective, (which as far as I know is
something D¹browski himself did not do explicitly) we can see it is not
something to be summarily dismissed as mere emotional whimsy. Nor, at the other
extreme, as something always to be taken religiously as a kind of mystical
certainty. At the lowest levels there are mere hunches, based on little
experience and still less reflection.
Whim and fancy and gratification of instinctual drives are uppermost. These
automatic, unreflected responses have frequently been identified with intuition,
leaving the concept there in its lowest unilevel sense to be neglected. It is no
wonder that intuition in this unilevel sense has been scorned as a source of
moral objectivity. At the lowest level, intuition would not be built upon
perspective, a sense of history, not even one's personal history, but, devoid of
retrospection and prospection, it would respond to the needs of the moment. One
would be merely responding to one's instincts with little or no appreciation of
or identification with another. Truly, perspective is missing at the lowest
levels and objectivity a product of happenstance.
At a
slightly higher level, one may be a little ambivalent about following personal
"hunches". One begins to get doubts about the ethics: "If it feels good,
do it". Fear of getting caught produces ambivalence. Conflict between moral
actions and their consequences may be resolved by rationalizations or putting
the blame "out there" — a kind of "the devil made me do it"
attitude. Psychological or physical conflicts between one's intuitions force one
to resort to rationalizations, or a giving up of autonomy in favour of the
comfort and acceptance promised by following those in authority or those who
have power. Some outside authority has the responsibility, whether it be a
"religious" guru, a rigid interpretation of the Bible, or a President as we
saw in the Watergate trials of a few years ago and are seeing currently in the
Iranscam investigation.
At a still
higher level, one will feel guilty about being so self-centred. Intuitions are
inhibited by self doubt and feelings of inferiority. One wonders whether what
one feels is right when subjected to the scrutiny of others, particularly if the
others have social support for being more logical and coolly rational. The
criteria of rightness have moved up the scale from mere power to respect for
"rationality".
An ethic of principle in the Kohlbergian sense may prevail, but a firm ethic of
care and responsibility in a full appreciation of relatedness has not yet
emerged. Positive maladjustment is difficult. One wonders if one can really
trust one's intuitions.
At the next
level, consciousness of one's own inner core of valuing becomes stronger and
more certain. Feelings of inferiority toward others yield more to feelings of
inferiority to one's own inner standards. Autonomy and an enhanced sense of
responsibility emerge in an authentic subjectivity. The "ought"
characteristics of previous levels, having moved far beyond neurotic tyranny,
have become now a moral imperative to strive for one's own personality ideal,
strongly fixed in relationships and bound by responsibility for others. This is
the sense of moral certainty Maslow found in his self-actualizers.
At the
highest levels, the centre of valuing, though based on an historical perspective,
and an appreciation of societal mores, integrates a more autonomous, authentic
subjectivity. It is the actualization of one's personality ideal — a
value-laden dynamism. Beyond polarities, as in Kohlberg's Stage 7, persons at
the highest level are grounded in an oneness with being. Their acute taste and
fineness of feeling for transcendent and moral reality give their words and
actions a clearness of profile that lifts them above the crowd. Their devotion
to relationships and a universal compassion may offend those devoted to narrower
concepts of justice. These narrower concepts of justice see morality solely in
terms of conflicts of rights, and tend to see relationships as exclusive rather
than inclusive. A vision of universal brotherhood and sisterhood (and whatever
is the combination of the two for which we as yet have no word) transcends petty
politics. Eminent persons at this highest level are moral leaders — leaders
who are sometimes followed by those who at some lower level can share their
vision, and sometimes persecuted and put to death by those who do not know what
is going on, or, on the other hand, know all too well what is going on and fear
the moral power of it. At this highest level there is consistency between goals
and intentions, between values and aims, between words and life lived. It is, in
the D¹browskian paradigm, the epitome of authentic subjectivity.
An
Aside
It seems, then, that the most promising approach in our search for the sources
of an objective morality is to explore the higher levels of intuition, enhancing
them by combining cognition, affect, imagination, reflection, the wisdom of
experience and sensitivity in a context of care and responsibility. Central to
this is D¹browski's dynamism of personality ideal. This dynamism is most active
at the level of secondary integration, having at lower levels caused the
individual to be troubled by the gap between what he is and what he "ought"
to be. His personal moral striving is the effort to close this gap. Now "is"
and "ought" are classical terms in moral philosophy, and for D¹browski to
claim that at Secondary Integration the two merge in some way is to make a
statement with powerful implications for moral philosophy. I would like to
interpret it in this way: The closure is realized in eminent human beings by the
identification to a higher degree between what is and what ought to be. What
ought to be and what is have become almost one. This is authenticity at its
highest levels. I have slipped in the words "almost one" when talking
about "is" and "ought" in higher level persons. This is because,
though I agree with D¹browski's statements that at Level "what ought to be
becomes what is" as a poetic statement of high morality, I find it can be
misunderstood. Sceptics are reluctant to accept this allusion to what seems to
be a state of perfection. We are well aware of the shortcomings of eminent
persons such as Gandhi. We are unwilling in a world clearly in a process to
postulate something which may appear to be a static stare of perfection. The
Theory of Positive Disintegration needs an application of process thinking to
Stage 5, and a further elaboration of the very highest levels of development. I
suggest that more attention could be paid to the religious, mystical and unitary
dimensions of this "ultimate" level of development.
I have, throughout, been emphasizing the highest levels of development, the most
authentic subjectivity, because, in that transcendent realm is where the
greatest objectivity is found, not because these eminent individuals have
discovered objectivity "out there" in things. They have discovered its
presence or absence in other people. Above all, they have constructed it in
lives lived authentically. The subject-object duality is overcome in a personal
oneness and an interpersonal oneness with others at the same high levels. There
is, according to D¹browski, a remarkable convergence among eminent persons on
their convictions of what is truly valuable and moral.
Objective
Hermeneutics
Now it is obvious that there are not many Gandhis or Schweitzers around. Eminent
people are few in number. But the rest of us at lower levels of development need
to be mere passive recipients of their moral teachings as in the tradition of
the philosopher kings. In fact we lower level people are challenged also to
construct moral objectivity.
If
objectivity is a "moment of scientific enquiry" (Habermas) then moral
objectivity is there in the "moment" of each Individual’s search into not
only the verbal teachings but the lives of eminent individuals. It is there to
the degree or level of authenticity that each has attained. Objectivity then is
not found in mere subjective feeling, nor in purely cognitive functioning nor in
blind conformity to the majority nor in passive acceptance of the teachings of
some moral authority. It is the "changing relationship between the
investigator and what he or she observes". It is created where humanness
and beauty and religion are created. It is created by human relationship. There
the "text" to be interpreted is not only the words of a famous moral teacher,
but the subject of hermeneutic perusal is also the life lived by that eminent
person. The objectivity of this "moment" is a function of the authenticity
of the teacher and the student, the observed and the observer, the "text"
and the intuition of the moral "hermeneuticist". Traditional
authority-centred approaches have depicted the "common man" as merely a
recipient of moral teachings, passively receiving "truths" from an authority
who, for some reason, knows better than he or she what should be done. The
approach presented here, however, emphasizes the authenticity of the eminent
person as the source of objectivity, but by stressing the hermeneutic
relationship of the teacher and student, it demands a measure of authenticity at
all levels of development. Ultimately, as with most things human, it is
relationship and responsibility that guide humans intuitively to an objective
morality.
Postscript
Besides the many other biases present in this paper, there is behind it all a
whole set of value judgments — most important of which are the value judgments
implicit in the term "higher level". Some will complain that I am using a
circular argument, postulating that an objective value hierarchy can be arrived
at by relating to the lives and teachings of eminent persons, while, all the
time, the selection of who these eminent persons are is based upon a whole
network or heterarchy of "accepted" values often only implicit. My reply to
this is that the consensual validity we seem to have regarding which concrete
persons exemplify the best of humanness may well be the most satisfactory
foundation we can achieve as a ultimate base for moral judgments. Objectivity is
objectivity; it is not certainty; nothing important in life is held together
with the bands of certainty. But, as Plato appreciated, and Whitehead after him,
the lives of the best human beings are held together by other "bands" —
the lines of beauty, harmony and relationship. In that beauty is goodness to
which, through fineness of feeling, individuals respond intuitively in accord
with their level of development. But all this talk of beauty and goodness, and
the religious dimension is another topic at another and deeper level. It is
deserving of fuller development as an enrichment of Dabrowski's Theory —
perhaps at the Fifth International Conference on the Theory of Positive
Disintegration.
