The Great Idea of Dialectic, by Mortimer J.
Adler, Ph.D. (Continued)
IV. Theories of dialectic
A theory of dialectic is, like a theory of
science or of art, a philosophical theory. If the
dialectician has a conception of dialectic itself,
in addition to having and using a certain method,
he does so in virtue of being a philosopher, not a
dialectician. On the other hand, his conception of
dialectic must square with the principles and
objectives of his method. We have already seen that
his method commits him to certain philosophical
positions -- about truth, human reason, the laws of
thought, language and meaning. It also commits him
to a certain theory of dialectic.
If theories of dialectic are philosophical
theories, and if the dialectical method we have
been describing is applicable to the diversity of
philosophical theories about any subject, then it
should be applicable to the apparently conflicting
theories of dialectic which are to be found in the
discussion of that subject. But the fact that the
method commits its user to one of these theories
would seem to impair, if not destroy, the
neutrality he is obligated to preserve. Here is a
case, therefore, where prudence might recommend not
venturing on the unfeasible -- a dialectically
neutral treatment of dialectic.
Let us, however, risk the imprudence and see
what can be said about the diverse theories of
dialectic. The most likely hypothesis is that these
theories only appear to be in conflict but
are actually in nonagreement rather than
disagreement. In the name of dialectic, they are
really treating three different things and
therefore cannot disagree. This does not exclude
the possibility that those who are talking about
the same theory of dialectic may disagree among
themselves.
To apply the foregoing hypothesis in detail to
the whole discussion of dialectic would require us
to do extensive research. But, perhaps, that is not
necessary for our present purposes. It may suffice
to sketch the general outlines of the hypothesis
from such acquaintance as we already have with the
historic discussion of dialectic.[12]
Our hypothesis is that the word dialectic
is used in the literature by three distinct groups
of theories. Each group of theories may include
diverse and even conflicting conceptions of
dialectic, but we are immediately concerned with
the subject that each group of theories is
considering. How shall these three subjects, each
called "dialectic," be identified?
We can identify one by saying that certain
authors who use the word dialectic have in
mind the process of philosophical inquiry itself
together with the kind of knowledge in which such
inquiry results. Let us refer to the subject thus
identified as "noetic dialectic," because all
conceptions of this subject regard it as a unique
way of knowing reality. Plato's conception of
dialectic, in those passages in The Republic
in which he identifies dialectic with philosophy as
knowledge of the ultimate realities, is the
archetypical representative of this group of
theories.[13]
We can identify a second by saying that certain
authors who use the word dialectic have in
mind the fundamental laws that govern all processes
of development in nature and history, such laws as
the unity of opposites, the transformation of
quantity into quality, and the negation of the
negation. Let us refer to the subject thus
identified as "regulative dialectic," because all
conceptions of this dialectic regard it, not only
as a way of knowing reality, but also as the way
reality itself behaves according to the dialectical
principles that regulate its processes.[14]
Hegel's conception of dialectic is, in one sense,
the leading representative of this group of
theories, though it must be added at once that the
Marxist conception, while following that of Hegel,
is also its leading opponent.[15]
We can identify a third subject by saying that
certain authors who use the word dialectic
have in mind a method auxiliary to philosophy by
which men think about things, not as they are in
themselves, but as they are reflected in human
thought. Let us refer to the subject thus
identified as "reflexive dialectic," because all
conceptions of this dialectic regard it, not as a
way of knowing reality directly nor as the
regulation of reality itself, but as an independent
discipline, separate from philosophy, which deals
reflexively with all the things that philosophy
deals with directly. It deals with them only as
they appear in the context of diverse philosophical
theories or doctrines. Aristotle's statement that
"dialectic is merely critical where philosophy
claims to know" is typical of this group of
theories.[16]
The conception of dialectic set forth in this
article clearly belongs to the third group of
theories. Dialectic, as we have been treating it,
is not identical with philosophy as knowledge of
reality, nor is it even one of the methods of
conducting philosophical inquiry. It could hardly
be mistaken for the inner logic of reality itself,
whose laws regulate all developments in nature,
history, and thought. It might, however, be thought
to resemble logic insofar as the science or art of
logic also deals with thought; but unlike formal
logic, it is not a science of the forms of thought;
and unlike the art of logic, it is not a method of
correct thinking. It is none of these. It is simply
a method of dealing with what men have actually
thought on the wide variety of fundamental subjects
about which they manifestly differ in their
views.
Before we consider how this conception of
dialectic relates to Aristotle's conception of the
same subject, let us first examine the three
subjects that we have just identified. They are
clearly distinct. In this respect, they are like
man-made law, natural law, and divine law. Just as
those who discuss only man-made law are simply in
nonagreement with those who discuss only divine
law, so those who consider only noetic dialectic or
only regulative dialectic are in nonagreement with
those who consider only reflexive dialectic. But in
the case of law, there is disagreement as to
whether there is only one kind of law or more.
Some, for example, hold that manmade law is the
only law, and deny that "natural law" is law or a
kind of law, while others affirm that natural law
and man-made law are both law, though of different
kinds. Is there a similar disagreement about
dialectic and its kinds?
There does not seem to be. Unlike theories of
law, no theory of dialectic holds, for example,
that regulative and reflexive dialectic are two
kinds of dialectic. No author can be construed as
asserting that some two or all three of these
subjects, all bearing the name "dialectic," must
belong to one general class as kinds. Hence no
issue about kinds of dialectic can be
constructed.
In the absence of controversy about dialectic in
general and in the absence of disagreement about
its kinds, exponents of the three major types of
theory are simply in nonagreement. Each is
concerned with a different subject. Yet all bear
the same name. A question arises, therefore, about
the name itself. Does it connote any elements that
are common to the three distinct subjects?
Any generic characterization of dialectic would
probably mention at least two things as common to
noetic, regulative, and reflexive dialectic: (1)
some principle whereby a diversity is unified or
opposites are reconciled;[17]
and (2) the assumption that dialectic effects or
facilitates the achievement of truth. But no one
claims that this, or any other, generic
characterization of dialectic identifies a general
class, of which noetic, regulative, and reflexive
dialectic are kinds. On the other hand, no
proponent of a particular theory of dialectic would
accept the two points stated above as sufficiently
precise to identify the dialectic he is trying to
define. What significance, then, does such a
generic characterization have?
The answer would seem to be that it throws light
on what is at least the nominal agreement that
exists among those who discuss dialectic. It
explains how they all happen to use one word to
designate the different subjects they are writing
about. Thus used, that word is not as plainly
equivocal as is the word bull when it is
used to refer to an animal and a proclamation. Some
threads of common meaning connect the three uses of
the word. But the word may have some systematic
ambiguity even though there is no controversy about
dialectic in general nor about its kinds at least
between exponents of one major theory and exponents
of another.[18]
This fact has critical significance for the
theory of dialectic set forth in these pages. It
means that there is no need to defend the dialectic
with which we have been concerned against theories
of noetic or regulative dialectic, for they on
their part do not deny the possibility or validity
of a reflexive dialectic. It also means that we can
apply our own dialectical method to different
theories of dialectic in the same way that we can
to other problems, for the fact that the method
commits its user to one of these theories does not
impair its neutrality. The theory of reflexive
dialectic does not challenge the validity of the
other theories of dialectic since these deal with
different subjects. The hypothesis that exponents
of the three major types of theory are simply in
nonagreement is not prejudicial to the sense or
truth of any of them.[19]
One problem remains, which we mentioned earlier
but postponed. It is the problem of the relation
between the conception of dialectic set forth in
this article and Aristotle's conception of the same
subject. The identification of that subject as a
reflexive dialectic -- a method of considering the
content of thought itself -- is acceptable to both
theories. But do they, considering this same
subject, (i) conceive it differently? If they do,
(ii) must we regard them as offering incompatible
definitions of dialectic? And if we have to
construct a definitional issue, (iii) can we do so
in a neutral manner?
The embarrassment of the third question can be
avoided if the two conceptions of reflexive
dialectic are not incompatible. It is certainly
possible for them to be different without being
incompatible, for one may simply be more complete
and precise than the other. The more adequate
conception can then be regarded as including rather
than rejecting the less adequate conception. Unless
the exponents of the less adequate conception
insisted upon its adequacy as stated, no issue
would arise between them and the exponents of the
more adequate conception, for they would see that
both held the same one, the latter in an improved
form.
Let us, then, compare the two conceptions -- the
Aristotelian conception and the conception
presented in this article. Because both regard
dialectic as reflexive, both are concerned with the
diversity of views that men hold on any subject.
Since both conceive dialectic as a method of
dealing, not with reality itself, but with the
subjects of human thought, it is inevitable that
both should be concerned with conflicts of opinion,
apparent or real; for the realm of thought is the
place where all contraries coexist. Finally, both
agree that dialectic, while not itself a method of
philosophical inquiry or a way of knowing reality,
is auxiliary to philosophy and serves the
philosopher in his pursuit of truth about the
reality or nature of things.[20]
How, then, do they differ? The difference
between the two conceptions must be said to lie in
how they further specify the purpose of the
dialectical method and its use. Is the method to be
used (1) by a participant in discussion, and for
the sake of getting at the doctrinal truth of the
matter under consideration, or (2) by an observer
of discussion, and for the sake of getting at the
dialectical truth about the controversy that such
discussion involves?
The dialectical method proposed in this article
clearly takes the second alternative. Its primary
aim, in constructing the controversy that is
implicit in a diversity of views, is to get at the
dialectical, not the doctrinal, truth about the
subject under discussion.[21]
Because this is its aim, detachment from all
competing doctrines and neutrality with respect to
them are essential to its proper use. Such
detachment and neutrality are usually better
maintained by an observer of discussion than by a
participant in it.
To be different, the Aristotelian conception of
dialectic would have to take the first alternative,
and this in fact it appears to do. If that
alternative makes the dialectical method
essentially polemical and partisan, then the two
conceptions are not only different but are also
clearly opposed; for, on this hypothesis, they
would attribute contrary properties to a reflexive
dialectic. One and the same method cannot be both
essentially neutral and polemical; it cannot be
simultaneously used for nonpartisan and partisan
purposes.
The hypothesis stated above must be rejected. It
violates what is common to the two conceptions,
however else they differ; namely, that dialectic is
auxiliary to the philosopher in his pursuit of
truth. Thus, no theory of reflexive dialectic can
consistently conceive such dialectic as purely
polemical and wholly partisan. Insofar as a method
is purely polemical in its aim and partisan in its
use, it may assist its user stubbornly to maintain
the truth he claims for his own doctrine; it may
help him to win forensic victories over his
opponents; but far from assisting him in getting at
the doctrinal truth about things, it will probably
prevent him from doing so if any part of the truth
resides in some doctrine other than his own. A
philosopher's loyalty is to the truth no matter
where it resides, not to the claims of truth he has
made for his own doctrine. If the ultimate
objective of a particular individual is to maintain
the truth of his own doctrine at all costs, then he
is no philosopher.
Hence it follows that a method which is
polemical and partisan, in the extreme sense
indicated above, does not meet the first
requirement of any theory of reflexive dialectic.
Polemic defeats rather than promotes the ultimate
objectives of philosophical inquiry. Indulgence in
polemics on all sides degrades discussion and
prevents fruitful debate from ever emerging when
men appear to differ.
These things being so, we return to the question
of how Aristotle's conception of the dialectical
method differs from the one set forth in this
article. We have already pointed out that Aristotle
conceives the method with which he is concerned as
an instrument to be used by a participant in
discussion, and with the primary aim of getting at
the doctrinal truth about matters on which there is
an apparent or real difference of opinion. If the
participant is a philosopher, not a sophist or a
merely disputatious person seeking a forensic
triumph, his being a participant will not make his
use of the method purely polemical and
partisan.[22]
He will try as a philosopher to temper his
partisanship with some effort at fairness and
impartiality in his treatment of conflicting views.
Nevertheless, he remains a partisan of the
particular doctrine to which he is attached.
Detachment from all conflicting doctrines is not,
therefore, essential to his use of dialectic; nor,
in Aristotle's conception, need the philosopher as
dialectician attempt to achieve such a
thoroughgoing neutrality. His primary aim is not to
get at the dialectical truth about a controversy
but rather at the doctrinal truth about the matters
in dispute, and though he may try to defend the
truth of his own doctrine, he remains hospitable to
whatever elements of truth can be found
elsewhere.[23]
As used by the philosopher for doctrinal, but
not polemical, purposes, dialectic, according to
Aristotle, is critical or exploratory. The
philosopher uses it to explore, from the point of
view of his own doctrine, the diversity of views on
whatever subject he is treating. He uses it
critically to examine and weigh divergent opinions,
in order to take from them whatever truth he can
find and thus perfect the truth of his own
doctrine. Aristotle himself exemplifies such use of
dialectic when he undertakes "to call into council
the views of those of our predecessors who have
declared any opinion on this subject, in order that
we may profit by whatever is sound in their
suggestions and avoid their errors."[24]
The difference between the two conceptions being
clear, one question remains. Are the two theories
of reflexive dialectic opposed? Do they advance
incompatible definitions of one and the same
subject? Only if the two theories exclude one
another are we faced with the embarrassing question
of whether we can use our own method to construct
in a thoroughly neutral manner the resultant issue
about the definition of dialectic.
In the light of what has been said, two
hypotheses suggest themselves, on neither of which
are we faced with that embarrassing question. The
first hypothesis is that each of the theories
defines a distinct kind of reflexive dialectic. The
second hypothesis is that there is only one kind of
reflexive dialectic, of which one of the two
theories offers a more explicit and adequate
conception than the other. Let us consider these
two hypotheses in turn.
On the first hypothesis, the two kinds of
reflexive dialectic would be distinguished by their
primary aim and use. To name the kind of dialectic
with which Aristotle is concerned, we can use the
key word in Aristotle's description of it --
"critical." In contrast, "constructive" is the key
word in the description we have given of the other
kind of reflexive dialectic. A critical dialectic
deals with the diversity of views from the point of
view of a doctrine that itself contributes to the
diversity; a constructive dialectic deals with
diversity without attachment to any particular
point of view. Whereas the primary aim of one is to
get at doctrinal truth, though it may incidentally
uncover some dialectical truth, the primary aim of
the other is to discover dialectical truth, while
at the same time indirectly serving the
philosopher's main quest of doctrinal truth.
Complete neutrality is, therefore, not essential to
the one as it is to the other.[25]
On this hypothesis, the two conceptions, each of
a different kind of dialectic, are not opposed.
They are no more incompatible than are the
conceptions of human and divine law, for instance,
when it is granted that these are two kinds of law.
But would the proponents of these two conceptions
be willing to grant that each defines a distinct
kind belonging to the same general class,
characterized as reflexive dialectic? There seems
to be no reason why proponents of the Aristotelian
theory would not admit that it defines only one of
two possible kinds. We, on our part, can also
accept the hypothesis that, while having certain
generic features in common, a critical and a
constructive dialectic are distinct kinds,
differentiated by their primary objectives and by
the way in which they are used. Yet we have one
reason for favoring a different hypothesis.
This other hypothesis lays greater emphasis on
what is common to the two theories. Both regard the
dialectical method as auxiliary to the
philosophical pursuit of truth about the nature of
things. Its ultimate purpose is to assist the
philosopher in ascertaining the doctrinal truth
about any matter under consideration. Now if
dialectic is not itself a method of philosophical
inquiry, which both theories admit, then perhaps it
can be said that its primary objective should be to
get at dialectical truth through the construction
of the controversy that is implicit in a diversity
of views about a particular subject. For this
primary purpose, complete neutrality is essential,
whether the method is used by a dialectical
observer or by a philosophical participant in the
discussion. To be a dialectician, in other words,
the philosophical participant must become, for a
time at least, as detached and impartial as he
could be if he were merely an observer.
According to this hypothesis, the theory of the
dialectical method as essentially constructive and
neutral offers the more explicit and adequate
conception of what a reflexive dialectic should be.
Insofar as the procedure is seen as critical rather
than constructive, and insofar as impartiality is
recommended rather than made obligatory, the
conception of the method fails to make explicit and
definite what is essential to dialectic as
auxiliary to philosophy. A critical method, used
directly for doctrinal purposes, is not a distinct
kind of reflexive dialectic. It represents only a
stage in the development of a constructive method,
used directly for dialectical purposes and only
indirectly for the attainment of doctrinal
truth.
This hypothesis about the relation of the two
theories seems to us preferable for the basic
reason that dialectical rather than doctrinal truth
should be the immediate and primary objective of a
method which is admittedly dialectical rather than
philosophical, because it is not itself a method of
philosophical inquiry but only auxiliary to such
inquiry. That reason, we think, justifies us in
regarding the traditional statement of the
Aristotelian theory as an inadequate conception of
the method. It is inadequate to the extent that it
fails to describe the procedure as constructive,
fails to insist upon neutrality as essential, and
fails to define the aim as the discovery of
dialectical truth, first for its own sake, and
ultimately for the sake of promoting the pursuit of
doctrinal truth.
If proponents of the Aristotelian theory were to
grant its inadequacy in these respects, then we
would have no reason to reject the Aristotelian
conception as false.[26]
We would simply take the position that our more
adequate conception includes their less adequate
conception and improves upon it by making explicit
and precise what should be said in a true
definition of reflexive dialectic.
The most important consequence of having
achieved the more adequate statement is the present
formulation of the method itself as a method of
constructing controversies with complete
neutrality. Yet the truth of the conception that
underlies the method by no means guarantees its
workability or its production of the results at
which it aims. These must be independently
judged.

12. We can, in other words, do
something like what we have done in the case of
law. Though we have referred to the discussion of
law as an "imaginary discussion," its main lines
were obviously drawn from the actual discussion of
that subject. We called it "imaginary" to indicate
that the dialectical hypothesis we presented was
merely a sketch based on our general acquaintance
with the historic discussion of law, and not a
detailed working out of the hypothesis in the light
of data supplied by protracted research.
13. See The Republic, Book
VI (511), Book VII (532-34). [GBWW, Vol.
7, pp. 387c, 397a-98c.] Other dialogues
emphasize the method or process of knowing rather
than the knowing itself; see the Sophist,
Statesman, and Philebus
[GBWW, Vol. 7]. Plato's
identification of the philosopher with the
dialectician gives rise to one conception of
philosophy and its method of inquiry. According to
an interesting analysis by Richard McKeon, the
dialectical philosopher, in Plato's sense of
"dialectical," is in method and character only one
of four types, the others being characterized by
other methods, which he calls "logistic,"
"problematic," and "operational," For McKeon's
description of the dialectical philosopher, see his
essay "Dialectic and Political Thought and Action,"
in Ethics 65, 1 (October 1954): pp. 1-33;
for his classification of the four types of
philosophy and philosophical method, see his
Thought, Action, and Passion (Chicago:
University of Chicago Press, 1954), pp. 85-88, and
his Freedom and History (New York: Noonday
Press, 1952).
14. For Hegel, the real is the
rational and the rational the real. Consequently,
for Hegel, dialectic is at once the inner logic of
both mind and reality; the laws of dialectic
regulate the development of thought and the
development of things. See Encyclopedia of the
Philosophical Sciences, Logic, chap. 6, sec.
81. "Wherever there is movement," Hegel writes,
"wherever there is life, wherever anything is
carried into effect in the actual world, there
Dialectic is at work. It is also the soul of all
knowledge which is truly scientific." Cf.
Philosophy of Right, Introduction, 31
[GBWW, Vol. 46, p. 19d], where Hegel
says that his dialectic "is not an activity of
subjective thinking applied to some matter
externally, but is rather the matter's very soul
putting forth its branches and fruit organically."
For the full exposition of the principles of
Hegel's regulative dialectic, see The Science of
Logic and Phenomenology of Mind, And for
Hegel's account of the history of dialectic, in
which he attributes certain anticipations of his
own theory to Plato and others, see the section
cited above in the Encyclopedia of the
Philosophical Sciences, and also his
Philosophy of History [GBWW, Vol.
46].
15. For Marx and Engels, the
dialectic of nature or of history is to be found in
the laws governing the transformations of matter
only. Borrowing from Hegel the conception of a
regulative dialectic and its laws, but differing
from Hegel about whether the laws of dialectic are
laws of matter or of mind, the Marxists developed
what they called a "dialectical materialism." See
F. Engels, Dialectics of Nature (New York,
1940); Ludwig Feuerbach and the Outcome of
Classical German Philosophy (New York, 1934);
and compare A Textbook of Marxist
Philosophy, prepared by the Leningrad Institute
of Philosophy and translated by A. C. Moseley
(London, 1937).
16. See Metaphysics, Book
IV, chap, 2, 1004b25 [GBWW, Vol. 8, p.
523d]. For Aristotle's conception of dialectic
as "a process of criticism," see his Topics;
especially Book I, chap. 2 [ibid., pp.
143d-44a], where he explains the usefulness of
the method as auxiliary to philosophy. Kant's
theory of dialectic is related to Aristotle's. In
the passage from the Metaphysics quoted
above, Aristotle distinguishes sophistry from
philosophy as well as dialectic. "Sophistry," he
writes, "is what appears to be philosophy, but is
not," Kant identifies ancient dialectic with
sophistry, "This art," he writes, "presented false
principles in the semblance of truth, and sought,
in accordance with these, to maintain things in
semblance. Amongst the Greeks the dialecticians
were advocates and rhetoricians who could lead the
populace wherever they chose, because the populace
lets itself be deluded with semblance.
In
Logic, also, it was for a long time treated of
under the name of the Art of Disputation, and for
so long all logic and philosophy was the
cultivation by certain chatter heads of the art of
semblance" (Introduction to Logic
[London: Longmans, Green & Co., 1885],
sec. ii). Kant then goes on to say that in his own
Logic he proposes to introduce "a critical
examination of this semblance" or sophistry under
the head of dialectic. In his Critique of Pure
Reason [GBWW, Vol. 42], he
called this division of his Transcendental Logic a
"Transcendental Dialectic."
17. As, for example, the
opposition of the One and Many in Plato's
dialectic, the opposition of thesis and antithesis
in Hegel's dialectic, and the opposition of
conflicting theories or arguments in Aristotle's
dialectic or Kant's.
18. The word induction provides
us with another example of the same situation. It
is not completely equivocal as it is used in
inductive logic and in algebra, yet those who are
concerned with mathematical induction and those who
are concerned with induction in the experimental
sciences are simply in nonagreement, They do not
think of mathematical and experimental induction as
belonging to the same general class; they do not
argue the question whether these two subjects are
both kinds of induction.
19. A particular individual who
uses the dialectical method as auxiliary to
philosophy may also be a philosopher who rejects
Plato's or Hegel's theory of dialectic as a false
philosophical theory of knowledge or reality. But
he would do so on philosophical grounds, not
because he used the dialectical method. As using
the method, he is not called upon to judge the
philosophical truth of these other theories of
dialectic. He can, therefore, remain dialectically
neutral in treating them, just as he can remain
dialectically neutral in treating theories of
freedom with which, as an individual philosophizing
about freedom, not as a dialectician, he may
disagree.
20. The Topics, that part
of his Organon in which Aristotle expounds
the rules of dialectic as a method to be used, also
contains a great deal that does not properly belong
to the art or method of dialectic at all. The
analysis of definitions which Aristotle gives
there, and his famous classification of the types
of predicates or "predicables," belongs rather to
the science of logic itself, in that division of
the science which Aristotle's medieval followers
called "material," as opposed to "formal," logic,
The justification for treating such matters in a
book ostensibly devoted to an art of disputation,
and to a critical method of dealing with the
conflict of opinions, may be that the arguments for
opposed positions often appeal to definitions and
often turn on how the disputants employ their
fundamental terms or predicates.
21. The fact that its primary aim
is to get at dialectical rather than doctrinal
truth does not exclude all interest in the latter.
On the contrary, if the discovery of dialectical
truth did not ultimately serve the pursuit of
doctrinal truth, the method would not be auxiliary
to philosophy as a pursuit of such truth about the
nature of things. But it aims at such truth
indirectly, not primarily or directly.
22. "In the second chapter of
Book I of the Topics [GBWW, Vol.
8, pp, 143d-44a], Aristotle distinguishes
between two main uses that can be made of the art
or method of dialectic. The first is the use that
can be made by men generally in "casual
encounters," wherein they are engaged in
disputation with one another and in efforts to
argue effectively or persuasively for their own
views. This use of dialectic associates it with
rhetoric. In fact, Aristotle declares, "rhetoric is
a branch of dialectic.
Both are methods of
providing arguments." (Rhetoric, Book I,
chap. 2, 1356a30-34 [GBWW, Vol. 9, pp,
595d-96a].) And in another place, he says that
"all men make use of both (i.e., rhetoric and
dialectic); for to a certain extent all men attempt
to discuss statements and to maintain them, to
defend themselves and to attack others." (Ibid.,
Book I, chap, I, 1354a3-6 [GBWW, Vol. 9,
p. 593a].) This first use of dialectic -- by
men generally in casual encounters -- verges on the
disputatious or polemical. But it is also clearly
distinct in Aristotle's mind from the use of
dialectic by philosophers. Aristotle describes that
second use as enabling the philosopher "to raise
searching difficulties on both sides of a subject
to detect more easily the truth and error
about the several points that arise."
(Topics, Book I, chap. 2, 101a34-37
[GBWW, Vol. 8, p. 144a].)
Aristotle's dialectic is sometimes spoken of as the
art of reasoning from merely probable premises in
the form of widely accepted opinions or the
opinions of experts, but that applies only to the
use of dialectic in casual encounters and for
forensic purposes. It does not apply to dialectic
as a method used by philosophers to get at the
doctrinal truth about a subject. If philosophers
were to engage in reasoning from accepted or expert
opinion, they would be arguing from authority
rather than from facts and principles.
23. This primary aim does not
exclude the possibility that indirectly or
incidentally the philosopher's doctrinal use of
dialectic may uncover or lead to the discovery of
some dialectical truths about the controversy in
which he is engaged. Cf. note 21.
24. On the Soul, Book I,
chap, 2, 403b22-24 [GBWW, Vol. 8, p,
633a].
25. As we have already seen, the
philosopher's doctrinal use of dialectic can and
should be tempered by some effort to be impartial,
or at least to avoid the unfairness and
subjectivity of merely polemical criticism or
refutation. In one place, Aristotle speaks of
dialectic as "an art of drawing opposite
conclusions impartially." (Rhetoric, Book I,
chap. 1, 1355a36 [GBWW, Vol. 9, p.
594d],) Furthermore, his statement that the
purpose of dialectic is "to raise searching
difficulties on both sides of a subject" and "to
detect
truth and error about the several
points that arise" (loc. cit.) suggests some
measure of impartiality. It is only when dialectic
is used, not by the philosopher but in "casual
encounters," that it is, as an art of disputation,
polemical in its partisanship. Cf. note 21.
26. We can offer one reason why
proponents of the Aristotelian theory should grant,
in terms of that theory itself, the inadequacy of
their conception of reflexive dialectic. In their
view, as well as in ours, the line between a
polemical misuse of the dialectical method and a
proper philosophical use of it lies in the fairness
and impartiality with which the philosopher, who is
making a doctrinal use of dialectic, treats the
doctrines of others. If he is truly a philosopher
rather than a polemicist, open to the truth
wherever it is found and not just a stubborn
defender of the claims he makes for the truth of
his own doctrine, then he is also truly a
dialectician to the extent that he achieves
impartiality in his treatment of whatever
philosophical diversity he finds. To recommend
neutrality, but not to make it obligatory, is
therefore an imperfect conception of the method, It
follows also that the philosopher should not use
dialectic in a merely critical manner to deal with
other doctrines from the point of view of his own.
He should try constructively to see the controversy
in which his own doctrine is included merely as one
among others.
