According to the standpoint set forth in the preceding discussion, the
key to a consistent and fruitful interpretation of consciousness and
psychology lies in behavior. If we turn now to the psychology of
introspection, which has been dominant so many years, we find a
standpoint and mode of procedure which, on the surface at least, is of a
radically different kind. It behooves us, therefore, to consider this
standpoint in some detail in order to justify the attempt to reinterpret
and "evaluate" it in the light of our own doctrine.
The point of departure for introspective psychology is to be found, so
it seems, not in the facts of behavior, but in the distinction between
focal and marginal experience. It is on this distinction that the
introspective psychologist bases the attempt to give a psychological
analysis and description of the contents of experience. To analyze and
describe the facts of consciousness is to bring the marginal
constituents of experience into the white light of attention. Analysis
and description are possible just because experience is so largely a
welter of elements that disguise their identity and character. In some
way these unrecognized and unidentified elements are constituents of the
total experience. To borrow the language of a writer quoted by James,
"However deeply we may suppose the attention to be engaged by any
thought, any considerable alteration of the surrounding phenomena would
still be perceived; the most abstruse demonstration in this room would
not prevent a listener, however absorbed, from noticing the sudden
extinction of the lights."[40] Or, as James remarks: "It is just like
the overtones in music. Different instruments give the 'same note,'
namely, various upper harmonics of it which differ from one instrument
to another. They are not separately heard by the ear; they blend with
the fundamental note and suffuse it, and alter it."[41] Let the
attention be directed to these overtones, however, and they at once
detach themselves from their surroundings and step forth into the light
of day. Even so the ticking of the clock may pass unnoticed in the sense
that it is an undiscriminated element in the background of our
consciousness; but if the ticking comes to a sudden stop, the feeling of
a void in our consciousness proclaims the fact that something has gone
out from it.
The observation and description of the facts of consciousness, then, is
based directly on the fact that experience, as the psychologist deals
with it, possesses a focus and margin. Nature as conceived by the
physical sciences presents no such distinction. The facts are what they
are, and their character as focal or marginal, as clear or obscure,
depends altogether upon their relation to an intelligence. Or we may say
that if the facts of experience were always focal and never marginal, it
would never occur to us to speak of consciousness as we do at present.
As long as we confine ourselves to a given color, shape or temperature,
as experienced focally, we are not dealing with consciousness, but with
objects. An analysis of such facts that does not bring in the marginal
is not an analysis of consciousness, but an analysis of physical
reality. Even if we consider non-physical objects, such as mathematical
or economic concepts, we find that our analysis is not psychological
as long as the marginal is left out. The consideration of the margin,
however, brings us into the presence of facts which are of a distinctive
kind and which warrant a new science. Let the margin be eliminated and
psychology disappears at the same time.
The psychological doctrine of focus and margin, then, is a matter of
fundamental importance. On the interpretation of this doctrine depend
our systems of psychology and of philosophy. What, then, is meant by
focus and margin? If we turn to our psychologies, we seem to be
confronted once more with something that everybody knows and nobody can
define. But since we have to do with a distinction, the obligation to
differentiate cannot be wholly ignored. Consciousness is sometimes
likened to a visual field and sometimes to the waves of the sea. Like
the visual field it has a foreground and a background, a near and a
remote, a center and a margin or periphery. The contents of
consciousness are vivid or clear in the center of this field and fade
away into vagueness or obscureness in proportion to their approach to
the periphery. Or, to take the other comparison, the focus may be
represented by the crest of a wave and the margin by what we may call
its base. This illustration has the advantage that it indicates the
difference between higher and lower degrees of concentration. As
concentration increases, the crest of the wave rises higher and its
width decreases, while the reverse is true where the concentration of
attention is less intense. All consciousness possesses the distinction
of focus and margin in some degree; however much we may be absorbed in
an object or topic, there is always an indirect mental vision that
informs us of other facts, which for the time being are in the
background of our consciousness.
For purposes of description a metaphor is at best a clumsy device. It
has a tendency to substitute itself for the thing to be described and
thus to conceal its limitations and inaccuracies. The present case is no
exception. I am forced to think that the visual field in particular is a
thoroughly vicious metaphor when employed to body forth the distinction
of focus and margin. Whatever this distinction may in the end turn out
to be, it is not such as this comparison would lead one to suppose.
Objects seen in indirect vision appear obscure and blurred precisely
because they are in the focus of consciousness. We get pretty much the
same sort of obscureness or blur on a printed page when we look at it in
indirect vision as we do when we look at it from a distance that is just
too great to make out the words or characters. What the illustration
shows is that things look different according as the circumstances under
which we see them are different, but what bearing this has on marginal
consciousness is not at all obvious to an unsophisticated intelligence.
When we speak of a focus and margin in consciousness, we are presumably
dealing with conscious fact. Now this illustration of the visual field
does not represent conscious fact. Ordinary perception carries with it
no sense of obscureness at all, and when it does we have exactly the
same kind of situation as when an object is too distant or in some other
way inaccessible to satisfactory perception. That is, the object
perceived is in the 'focus' and not in the margin. The obscureness of
objects when seen with the margin of the retina has no more to do with
the margin of consciousness than the obscureness caused by an attack of
dizziness or by a morning fog.
It will be said, perhaps, that consciousness may be unclear even though
there be no sense of unclearness, that there is such a thing as
intrinsic clearness, quite apart from obstacles and problems. In other
words, the same sensation is capable of realizing various degrees of
clearness. It is not at all obvious, however, why the different
experiences that are concerned in such a comparison should be called the
same sensation. As long as we abstract from objective reference, each
sensation is just what it is and there is no opportunity to make
comparisons on the basis of clearness. A sensation as such--if we are
bound to speak of sensations--can by no possibility be an obscure
sensation, for the trait that we call obscureness or vagueness
constitutes the intrinsic being of that sensation. If we permit
ourselves to speak of clearness at all, we should rather say that it
possesses a maximum of clearness, since it has managed to express or
present its whole nature with not one trait or feature lacking. What
more could be demanded, in the way of clearness, of any conscious fact
than that it should body forth every detail that it possesses?
If sensations or states of consciousness possess degrees of clearness,
it seems to follow that we may scrutinize them for the purpose of
discovering characteristics that were present though scarcely
perceived, in much the same way that the polishing of old furniture
brings out the grain in the wood. But such a parallel, I submit, is
plain nonsense. The supposition that consciousness is something that in
due time and with good fortune may attain consciousness is too absurd
for discussion, even though it is a supposition that plays a
considerable role in present-day psychology.
The purpose of the discussion, up to this point, has not been to deny
the validity of the distinction between focus and margin, but to insist
upon the necessity of reconsidering the meaning of this distinction, if
we are to attain to a workable definition of consciousness and a
fruitful or even intelligible conception of the problem of psychology. I
have endeavored to show, in the first place, that the doctrine of focus
and margin involves the _raison d'etre_ of psychology. Apart from this
doctrine we have no task or problem that psychology can claim as its
distinctive possession. The analysis of what is in the focus of
consciousness is adequately provided for in the other sciences; it is
only with the introduction of what is called the margin that an
enterprise of a different kind becomes necessary. But, secondly, this
distinction of focus and margin cannot be drawn on the basis of the
experienced contrast between clearness and obscureness. The very fact
that anything is experienced as obscure means that it is an object of
attention, or, in other words, that it is in the focus of consciousness
and not in the margin. The comparison of focus and margin with direct
and indirect vision is misleading, because it suggests that experiences
are marginal in proportion as they are felt as obscure. And, thirdly, if
we undertake to distinguish between focus and margin on the basis of a
difference in clearness or vividness of which no note is taken at the
time, we encounter the difficulty that experience or consciousness,
taken abstractly, does not admit of such variations in degree, and so
this criterion likewise goes by the board.
The situation is indeed peculiar. That there is a realm of psychological
fact is universally conceded. As a consequence of this conviction a
great body of fact and of doctrine has been built up. It would be folly
to deny either the distinctiveness or the significance of this
achievement. And yet James's description of psychology as "a string of
raw facts; a little gossip and wrangle about opinions; a little
classification and generalization on the mere descriptive level; a
strong prejudice that we _have_ states of mind and that our brain
conditions them,"[42] is not wholly untrue even today. It is even
possible for a present-day critic to outdo James and maintain that the
legitimacy of psychology as a separate inquiry is a matter of faith
rather than of sight. The 'raw facts' of which James speaks resolve
themselves into physical and physiological material on the one hand and
metaphysical dogmas on the other; the gossip and wrangle are largely
over fictitious problems; the classifications and generalizations as a
rule involve trespassing on other fields; the prejudice that we have
states of mind has less standing-ground today than it had twenty years
ago. In other words, there is still plausible ground for James's
pessimistic comment: "This is no science, it is only the hope of a
science." A situation such as this carries with it the insistent
suggestion that the trouble lies, not primarily in the nature of the
subject-matter, but in our conception of the problem. "The matter of a
science," as James says, "is with us." And if the distinction of focus
and margin constitutes the starting-point and justification for a
science of psychology, a better understanding of this distinction will
mean a more adequate appreciation of the problem with which psychology
has to deal.
As a starting-point for a reconsideration of focus and margin, we may
take those experiences in which the distinction of clearness and
obscureness is presented as an experienced fact. Let us then turn once
more to the familiar illustration of the visual field. "When we look at
a printed page, there is always some one portion of it, perhaps a word,
which we see more clearly than we do the rest; and out beyond the margin
of the page we are still conscious of objects which we see only in a
very imperfect way."[43] That is, we appreciate the distinction between
what lies in the center of our visual field and what is more remote,
just because in this experiment we are trying to see what lies beyond
the center without turning our eyes in that direction. We set ourselves
the task of seeing what is on the page, and at the same time we
interpose an artificial obstacle. Hence the sense of effort, and the
contrast between what is clear and what is obscure. The present
experience is obscure, not inherently, but only with reference to a
certain problem or question. It is inadequate as an anticipation of
further experience. The contrast between clear and obscure is created by
our attempt to overcome the difficulty, and is therefore absent from
ordinary, unobstructed visual perception.
The situation described in the following familiar quotation from James
is an illustration of the same thing: "Suppose we try to recall a
forgotten name. The state of our consciousness is peculiar. There is a
gap therein; but no mere gap. It is a gap that is intensely active. A
sort of wraith of the name is in it, beckoning us in a given direction,
making us at moments tingle with the sense of our closeness, and then
letting us sink back without the longed-for term."[44]
'I met this man on the train, and later at the reception; but what is
his name?' The struggle rends our consciousness in twain. The occasions
of our meeting, his appearance, his conversation, are solid fact, yet
all suffused with the pervasive, evanscent "wraith" that tantalizes us
with glimpses which half reveal and half conceal the name we seek to
grasp.
To account for such experiences simply in terms of half-submerged
"sensations" and "images" is to do violence to all the requirements for
clear thinking. If we rule out explanations of this kind, we are
evidently forced to the conclusion that these experiences are obscure,
not in themselves or in the abstract, but with reference to the function
of putting us in possession of the name to which they are inadequate
clues. It is the subsequent, satisfactory experience of the name which
furnishes our standard for clearness; in other words, the implications
of obscureness are of a functional, and not of a static or structural,
kind. The marginal character of an experience is simply a reference to
its function as a clue or cue to some further experience, i.e., a
reference to its character as a changing stimulus. Or we may say that
the distinction between focus and margin is just another aspect of the
distinction between the conditions for further activity and the
incompleteness which leads to further adjustment. The transfer of the
future into the present gives us a fact, here and now, and in this
respect the experience is entirely focal in character, and as such it is
subject-matter for the various sciences. Whatever the nature of the
experience, it is just what it is, and not something else. With respect
to the further experience, however, which it conditions or for which it
prepares the way, the present experience is entirely marginal, i.e., in
its character as a changing stimulus it is subject-matter for
psychology. The distinction of focus and margin, then, is based
ultimately upon the function of experience in the control of behavior.
The given situation is a present fact and is in functional change; or,
in terms of our present discussion, it has both a focus and a margin. As
present fact it is a reality which requires recognition in the form of
adjustment; as in functional change it provides opportunity for bringing
the adjustment to fruition. That is, the experience both sets a task or
makes a demand and it points the way. The distinction is a distinction
of function, not of static existence, and it is this distinction which
is represented by the contrast of focus and margin.
If we compare this interpretation of focus and margin with that of
traditional psychology, we find that the latter construes the relation
of the present to the future experience wholly in static terms, the
functional relation being left out of account. The later experience is
read back into its predecessor in the form of dim or marginal images,
which need but show themselves more completely to make the two
identical. If these sensations were intended only as symbols of a
functional relationship, it would perhaps be scarcely worth while to
enter a protest against them. But when the functional relationship is
quite overlooked, the explanation that is given becomes exceedingly
dubious. The ticking of the clock, for example, that is present, though
unnoticed, the overtones of the note that suffuse the whole without
diverting attention to their individual qualities,--in what precise way
are facts of this kind concerned in the description of the experience
which they modify? A study of the clock or of the overtones can hardly
pass as an analysis of consciousness; it is too obviously an affair of
physics. Such a study becomes merely an excuse for repeating the
analyses of physics and reading them off in terms of sensations and
images. Moreover, the transfer of all this material to consciousness
looks suspiciously like a transaction in mental chemistry. Where, then,
is psychology to gain a foothold? What is the meaning of these uncanny
sensations and images, which nobody experiences, unless it be their
character as symbols of adjustment? They have no legitimate status, and
psychology, by consequence, has no legitimate problem, except in so far
as they represent those possible acts of adaptation which are the sole
and proper concern of psychology.
It remains to point out briefly the bearing of these results on what is
called "the method of introspection." We are sometimes assured that
introspection has discarded the belief in a separate mental stuff or
subject-matter, but there is ground for the suspicion that such
protestations are made in the same spirit that we affirm our belief in
the Ten Commandments or the Golden Rule, with no thought of being taken
seriously. At all events, without a literal "looking within" it seems to
become exceedingly difficult to differentiate introspection from
ordinary observation as practised in the other sciences. The reason for
this difficulty is that there is nothing left in introspection by which
it can be differentiated. The term introspection properly designates,
not a method but a problem; the problem, namely, of interpreting given
facts with reference to their function in the control of behavior. If
psychology is to justify its claim to the status of a science, it is in
duty bound to secure for itself both an objective criterion for the
adjudication of disputes which otherwise are of necessity interminable,
and a subject-matter that is not simply a heritage of metaphysical
prejudice, but a realm of fact that is attested by everyday observation
and experience.
