First it is clear that a reform of logic based upon the restoration of
knowing to its connections with other acts will begin with a chapter
containing an account of these other operations and the general
character of this connection.[13] Logical theory has been truncated. It
has tried to begin and end in the middle, with the result that it has
ended in the air. Logic presents the curious anachronism of a science
which attempts to deal with its subject-matter apart from what it comes
from and what comes from it.
The objection that such a chapter on the conditions and genesis of the
operations of knowing belongs to psychology, only shows how firmly fixed
is the discontinuity we are trying to escape. As we have seen, the
original motive for leaving this account of genesis to psychology was
that the act of knowing was supposed to originate in a purely psychical
mind. Such an origin was of course embarrassing to logic, which aimed
to be scientific. The old opposition between origin and validity was due
to the kind of origin assumed and the kind of validity necessitated by
the origin. One may well be excused for evading the question of how
ideas, originated in a purely psychical mind, can, in Kant's phrase,
"have objective validity," by throwing out the question of origin
altogether. Whatever difficulties remain for validity after this
expulsion could not be greater than those of the task of combining the
objective validity of ideas with their subjective origin.
The whole of this chapter on the connection between logical and
non-logical operations cannot be written here. But its central point
would be that these other acts with which the act of knowing must have
continuity are just the operations of our unreflective conduct. Note
that it is "unreflective," not "unconscious," nor yet merely
"instinctive" conduct. It is our perceptive, remembering, imagining,
desiring, loving, hating conduct. Note also that we do not say
"psychical" or "physical," nor "psycho-physical" conduct. These terms
stand for certain distinctions in logical conduct,[14] and we are here
concerned with the character of non-logical conduct which is to be
distinguished from, and yet kept in closest continuity with, logical
conduct.
If, here, the metaphysical logician should ask: "Are you not in this
assumption of a world of reflective and unreflective conduct and
affection, and of a world of beings in interaction, begging a whole
system of metaphysics?" the reply is that if it is a metaphysics bad
for logic, it will keep turning up in the course of logical theory as a
constant source of trouble. On the other hand, if logic encounters grave
difficulties when it attempts to get on without it, its assumption, for
the purposes of logic, has all the justification possible.
Again it will be urged that this alleged non-logical conduct, in so far
as it involves perception, memory, and anticipation, is already
cognitive and logical; or if the act of knowing is to be entirely
excluded from logic, then, in so far as what is left involves objective
"terms and relations," it, also, is already logical. And it may be
thought strange that a logic based upon the restoration of continuity
between the act of knowing and other acts should here be insisting on
distinction and separation. The point is fundamental; and must be
disposed of before we go on. First, we must observe that the unity
secured by making all conscious conduct logical turns out, on
examination, to be more nominal than real. As we have already seen, this
attempt at a complete logicizing of all conduct is forced at once to
introduce the distinction of "explicit" and "implicit," of "conscious
and unconscious" or "subconscious" logic. Some cynics have found that
this suggests dividing triangles into explicit and implicit triangles,
or into triangles and sub-triangles.
Doubtless the attempt to make all perceptions, memories, and
anticipations, and even instincts and habits, into implicit or
subconscious inference is an awkward effort to restore the continuity of
logical and non-logical conduct. Its awkwardness consists in attempting
to secure this continuity by the method of subsumptive identity, instead
of finding it in a transitive continuity of function;--instead of seeing
that perception, memory, and anticipation _become_ logical processes
when they are employed in a process of inquiry, whose purpose is to
relieve the difficulties into which these operations in their function
as direct stimuli have fallen. Logical conduct is constituted by the
cooeperation of these processes for the improvement of their further
operation. To regard perception, memory, and imagination as implicit
forms or as sub-species of logical operation is much like conceiving the
movements of our fingers and arms as implicit or imperfect species of
painting, or swimming.
Moreover, this doctrine of universal logicism teaches that when that
which is perfect is come, imperfection shall be done away. This should
mean that when painting becomes completely "explicit" and perfect,
fingers and hands shall disappear. Perfect painting will be the pure
essence of painting. And this interpretation is not strained; for this
logic expressly teaches that in the perfected real system all temporal
elements are unessential to logical operations. They are, of course,
_psychologically_ necessary for finite beings, who can never have
perfectly logical experiences. But, from the standpoint of a completely
logicized experience, all finite, temporal processes are accidents, not
essentials, of logical operations.
The fact that the processes of perception, memory, and anticipation are
transformed in their logical operation into sensations and universals,
terms, and relations, and, as such, become the subject-matter of logical
theory, does not mean that they have lost their mediating character, and
have become merely objects of logical contemplation at large. Sensations
or sense-data, and ideas, terms and relations, are the subject-matter of
logical theory for the reason that they sometimes succeed and sometimes
fail in their logical operations. And it is the business of logical
theory to diagnose the conditions of this success and failure. If, in
writing, my pen becomes defective and is made an object of inquiry, it
does not therefore lose all its character as a pen and become merely an
object at large. It is _as_ an instrument of writing that it is
investigated. So, sense-data, universals, terms, and relations as
subject-matter of logic are investigated in their character _as_
mediators of the ambiguities and conflicts, of non-logical experience.
If the operations of habit, instinct, perceptions, memory, and
anticipation _become_ logical, when, instead of operating as direct
stimuli, they are employed in a process of inquiry, we must next ask:
(1) under what conditions do they pass over into this process of
inquiry? (2) what modifications of operation do they undergo, what new
forms do they take, and what new results do they produce in their
logical operations?
If the act of inquiry be not superimposed, it must arise out of some
specific condition in the course of non-logical conduct. Once more, if
the alarm be sounded at this proposal to find the origin of logical in
non-logical operations it must be summarily answered by asking if the
one who raises the cry finds it impossible to imagine that one who is
not hungry, or angry, or patriotic, or wise may become so. Non-logical
conduct is not the abstract formal contradictory of logical conduct any
more than present satiety or foolishness is the contradictory of later
hunger or wisdom, or than anger at one person contradicts cordiality to
another, or to the same person, later. The old bogie of the logical
irrelevance of origin was due to the inability to conceive continuity
except in the form of identity in which there was no place for the
notion of _growth_.
The conditions under which non-logical conduct _becomes_ logical are
familiar to those who have followed the doctrines of experimental logic
as expounded in the discussions of the past few years. The
transformation begins at the point where non-logical processes instead
of operating as direct unambiguous stimuli and response become ambiguous
with consequent inhibition of conduct. But again this does not mean that
at this juncture the non-logical processes quit the field and give place
to a totally new faculty and process called reason. They stay on the
job. But there is a change in the job, which now is to get rid of this
ambiguity. This modification of the task requires, of course,
corresponding modification and adaptation of these operations. They take
on the form of sensations and universals, terms and relations, data and
hypotheses. This modification of function and form constitutes "reason"
or, better, reasoning.
Here some one will ask, "Whence comes this ambiguity? How can a mere
perception or memory as such be ambiguous? Must it not be ambiguous to,
or for, something, or some one?" The point is well taken. But it should
not be taken to imply that the ambiguity is for a merely onlooking,
beholding psychical mind--especially when the perception is itself
regarded as an act of beholding. Nor are we any better off if we suppose
the beholding mind to be equipped with a faculty of reason in the form
of the principle of "contradiction." For this throws no light on the
origin and meaning of ambiguity. And if we seek to make all perceptions
as such ambiguous and contradictory, in order to make room for, and
justify, the operations of reason, other difficulties at once beset us.
When we attempt to remove this specific ambiguity of perceptive conduct
we shall be forced, before we are through, to appeal back to perception,
which we have condemned as inherently contradictory, both for data and
for verification.
However, the insistence that perception must be ambiguous to, or for,
something beyond itself is well grounded. And this was recognized in the
statement that it is equivocal as a stimulus in conduct. There need be
no mystery as to how such equivocation arises. That there is such a
thing as a conduct at all means that there are certain beings who have
acquired definite ways of responding to one another. It is important to
observe that these forms of interaction--instinct and habit, perception,
memory, etc.--are not to be located in either of the interacting beings
but are functions of both. The conception of these operations as the
private functions of an organism is the forerunner of the
epistemological predicament. It results in a conception of knowing as
wholly the act of a knower apart from the known. This is the beginning
of epistemology.
But to whatever extent interacting beings have acquired definite and
specific ways of behavior toward one another it is equally plain--the
theory of external relations notwithstanding--that in this process of
interaction these ways of behavior, of stimulus and response, undergo
modification. If the world consisted of two interacting beings, it is
conceivable that the modifications of behavior might occur in such close
continuity of relation to each of the interacting beings that the
adjustment would be very continuous, and there might be little or no
ambiguity and conflict. But in a world where any two interacting beings
have innumerable interactions with innumerable other beings and in all
these interactions modifications are effected, it is to be expected that
changes in the behavior of each or both will occur, so marked that they
are bound to result in breaks in the continuity of stimulus and
response--even to the point of tragedy. However, the tragedy is seldom
so great that the ambiguity extends to the whole field of conduct.
Except in extreme pathological cases (and in epistemology), complete
skepticism and aboulia do not occur. Ambiguity always falls within a
field or direction of conduct, and though it may extend much further,
and must extend some further than the point at which equivocation
occurs, yet it is never ubiquitous. An ambiguity concerning the action
of gravitation is no less specific than one regarding color or sound;
indeed, the one may be found to involve the other.
Logical conduct is, then, conduct which aims to remove ambiguity and
inhibition in unreflective conduct. The instruments of its operation are
forged from the processes of unreflective conduct by such modification
and adaptation as is required to enable them to accomplish this end.
Since these logical operations sometimes fail and sometimes succeed they
become the subject-matter of logical theory. But the technique of this
second involution of reflection is not supplied by some new and unique
entity. It also is derived from modifications of previous operations of
both reflective and non-reflective conduct.
While emphasizing the continuity between non-logical and logical
operations, we must keep in mind that their distinction is of equal
importance. Confusion at this point is fatal. A case in point is the
confusion between non-logical and logical observation. The results of
non-logical observation, e.g., looking and listening, are direct stimuli
to further conduct. But the purpose and result of _logical_ observation
are to secure data, not as direct stimuli to immediate conduct but as
stimuli to the construction or verification of hypotheses which are the
responses of the _logical_ operation of imagination to the data.
Hypotheses are anticipatory. But they differ from non-logical
anticipation in that they are tentatively, experimentally, i.e.,
logically anticipatory. The non-logical operations of memory and
anticipation lack just this tentative, experimental character. When we
confuse the logical and non-logical operations of these processes the
result is either that logical processes will merely repeat non-logical
operations in which case we have inference that is tautologous and
trifling; or the non-logical will attempt to perform logical operations,
and our inference is miraculous. If we seek to escape by an appeal to
habit, as in empiricism, or to an objective universal, as in idealism
and neo-realism, we are merely disguising, not removing the miracle.
It may be thought that this confusion would be most likely to occur in a
theory which teaches that non-logical processes are carried over into
logical operations. But this overlooks the fact that the theory
recognizes at the same time that these non-logical operations undergo
modification and adaptation to the demands of the logical enterprise. On
the other hand, those who make all perceptions, memory, and
anticipation, not to speak of habit and instinct, logical, have no basis
for the distinction between logical and non-logical results; while those
who refuse to give the operations of perception, memory, etc., any place
in logic can make no connections between logical and non-logical
conduct. Nor are they able to distinguish in a specific case truth from
error.
In all logics that fail to make this connection and distinction between
logical and non-logical operations there is no criterion for data. If
ultimate simplicity is demanded of the data, there is no standard for
simplicity except the _minimum sensibile_ or the _minimum intelligibile_
which have recently been resurrected. On the other hand, where
simplicity is waived, as in the logic of objective idealism, there is
still no criterion of logical adequacy. But if we understand by
_logical_ data not anything that happens to be given, but something
_sought_ as material for an hypothesis, i.e., a proposed solution
(proposition) of an ambiguous object of conduct and affection, then
whatever results of observation meet this requirement are logical data.
And whenever data are found from which an hypothesis is constructed that
succeeds in abolishing the ambiguity, they are simple, adequate, and
true data.
No scientist, not even the mathematician, in the specific investigations
of his field, seeks for ultimate and irreducible data at large. And if
he found them he could not use them. It is only in his metaphysical
personality that he longs for such data. The data which the scientist in
any specific inquiry seeks are the data which suggest a solution of the
question in which the investigation starts. When these data are found
they are the "irreducibles" of that problem. But they are relative to
the question and answer of the investigation. Their simplicity consists
in the fact that they are the data from which a conclusion can be made.
The term "simple data" is tautologous. That one is in need of data more
"simple" means that one is in need of new data from which an hypothesis
can be formed.
It is true that the actual working elements with which the scientist
operates are always complex in the sense that they are always something
more than elements in any specific investigation. They have other
connections and alliances. And this complexity is at once the despair
and the hope of the scientist; his despair, because he cannot be sure
when these other connections will interfere with the allegiance of his
elements to his particular undertaking; his hope, because when these
alliances are revealed they often make the elements more efficient or
exhibit capacities which will make them elements in some other
undertaking for which elements have not been found. A general resolves
his army into so many marching, eating, shooting units; but these
elements are something more than marching, shooting units. They are
husbands and fathers, brothers and lovers, protestants and catholics,
artists and artisans, etc. And the militarist can never be sure at what
point these other activities--I do not say merely external
relationships--may upset his calculations. If he could find units whose
whole and sole nature is to march and shoot, his problem would be, in
some respects, simpler, though in others more complex. As it is, he is
constantly required to ask how far these other functions will support
and at what point they will rebel at the marching and shooting.
Such, in principle, is the situation in every scientific inquiry. When
the failure of the old elements occurs it is common to say that
"simpler" elements are needed. And doubtless in his perplexity the
scientist may long for elements which have no entangling alliances,
whose sole nature and character is to be elements. But what in fact he
actually seeks in every specific investigation are elements whose nature
and functions _will not interfere_ with their serving as units in the
enterprise in hand. But from some other standpoint these new elements
may be vastly more complex than the old, as is the case with the modern
as compared with the ancient atom. When the elements are secured which
operate successfully, the non-interfering connections can be ignored and
the elements can be treated as if they did not have them,--as if they
were metaphysically simple. But there is no criterion for metaphysical
simplicity except operative simplicity. To be simple is to serve as an
element, and to serve as an element is to be simple.
It is scarcely necessary in view of the foregoing to add that the data
of science are not "sense-data," if by sense-data be meant data which
are the result of the operations of sense organs alone. Data are as much
or more the result of operations, first, of the motor system of the
scientist's own organism, and second, of all of the machinery of his
laboratory which he calls to his aid. Whether named after the way they
are obtained, or after the way they are used, data are quite as much
"motor" as "sense." Nor, on the other hand, are there any purely
intellectual data--not even for the mathematician. Some mathematicians
may insist that their symbols and diagrams are merely stimuli to the
platonic operation of pure and given universals. But until mathematics
can get on without these symbols or any substitutes the intuitionist in
mathematics will continue to have his say.
Wherever the discontinuity between logical operations and their acts
persists, all the difficulties with data have their correlative
difficulties with hypotheses. In Mill's logic the account of the origin
of hypotheses oscillates between the view that they are happy guesses
of a mind composed of states of consciousness, and the view that they
are "found in the facts" or are "impressed on the mind by the facts."
The miracle of relevancy required in the first position drives the
theory to the second. And the tautologous, useless nature of the
hypothesis in the second forces the theory back to the first view. In
this predicament, little wonder Mill finds that the easiest way out is
to make hypotheses "auxiliary" and not indigenous to inference. But this
exclusion of hypotheses as essential leaves his account of inference to
oscillate between the association of particulars of nominalism and
scholastic formalism, from both of which Mill, with the dignified zeal
of a prophet, set out to rescue logic.
Mill's rejection of hypotheses formed by a mind whose operations have no
discoverable continuity with the operations of things, or by things
whose actions are independent of the operations of ideas, is forever
sound. But his acceptance of the discontinuity between the acts of
knowing and the operation of things, and the conclusion that these two
conceptions of the origin and nature of hypotheses are the only
alternatives, were the source of most of his difficulties.
