Scholastic Dialectic

Latin scholasticism actually evinced more concern with fine points of philosophical argument than any broad philosophical tendency prior to modern analytic philosophy. Many authors followed a pattern in which some assertion would be introduced, followed by arguments for and against the assertion, followed by replies of each side to the arguments of the other, thus simulating a formal debate. Only then would the author conclude with “I say…” and give his own reasons. This resembles what happens when people play chess against themselves, still trying to win every time they turn the board around. It promotes a kind of intellectual honesty and thoroughness.

In the 2nd century BCE, the skeptical Platonist Carneades had bewildered the Romans by arguing both sides of a question with equal vigor. Latin scholastics did take a position by the end of their discourses, but scholars have sometimes wondered if all of these conclusions should be taken at face value, because sometimes earlier arguments for an opposed point of view seem stronger. For some authors, making a strong case for an argument and then appearing to reject it may have been a way to preserve controversial arguments for posterity.

This was a particular historical form, broadly influenced by both Platonic and Aristotelian dialectic. Various conventions in the use of natural language were developed to promote unambiguous interpretations of logical meaning. The style in which arguments were presented can sometimes seem imposing due to its complex semi-formal character, particularly in authors like Aquinas, but the spirit of debate was quite lively.

I have noted that the Arabic tradition had tended to downplay the role of dialectic and practical judgment in Aristotle, in favor of stricter deductive “science”. The Latin tradition absorbed this reverence for deductive science, while re-establishing a strong role for a kind of dialectic.

Constructive Realism?

I’ve previously suggested there should be an overlap between non-naive realism and non-subjective idealism, and indicated a preference for constructive reasoning in formal contexts. The other day I referred in passing to the “constructive-flavored” character of the principle of sufficient reason or “nothing comes from nothing”. The “flavored” suffix refers to the fact that the contexts in which the principle applies are not formal, so the application of “constructive” is somewhat metaphorical. But the connection with sufficient reason is easy to see. In constructive reasoning, every step requires evidence. Therefore, all assumptions are hypothetical or defeasible. No valid assertion “comes from nothing”. I was talking about secondary causes and neoplatonic “procession” and what not as a sort of illustration of this on the side of the development or unfolding of conceptual content. In another recent post, I was stressing the role of dialectic and practical judgment over pure deductive reasoning in Aristotle. Putting all this together, it occured to me that “non-naive realism” might be further specified as “constructive realism” (now dropping the suffix for convenience) in which the constructively flavored activity consists of said dialectic and practical judgment.

In contrast to Michael Dummet, I don’t at all see why constructive needs to mean “anti-realist”, and I don’t like such dichotomous divisions in general. A constructive realism would be about achieving realism through the mediation of concrete dialectic and practical judgment and development of content (the only way it really can be done, I think). It would thus be a mediated realism, in which the thickness of the mediation yields the substantiality of the reality.

Belief

Al-Farabi’s 10th century reading of Aristotle — which set many patterns for later Arabic, Hebrew, and Latin developments — was generally historically salutary, but among other things reflected a definite “theoreticist” bias, strongly privileging episteme (“deductive science”, or knowledge in a strong sense) over dialectic and practical judgment. It was not until Kant that this bias began to be counterbalanced again. Even Hegel still understated the role of dialectic and practical judgment in Aristotle. (See also Aristotelian Demonstration; The Epistemic Modesty of Plato and Aristotle.)

It is in this context of dialectic and practical judgment that I want to think about belief. I have a bit of a double meaning in mind, recalling both discussions among analytic philosophers and questions about faith and reason.

To the analytic philosophers, I want to recommend a pragmatically flavored emphasis on sound belief as a result of dialectic and practical judgment, to replace many uses of “true belief” that is supposed to simply correspond to a state of affairs. (See also “Said Of”; Brandom on Truth; Commitment.)

In the context of faith and reason, I want to respectfully recommend that faith should be decoupled from a list of things one is supposed to assert or “believe”. I have always believed that the highest concept of faith is instead a pure affective attitude and way of being and doing that resembles hope and charity and an anticipation of grace. (See also Theology.)

Subject, Object

Subject and object are functional roles. There is no guarantee that either has any stronger unity than is required by its role. Referentially, members of a subject-object pair may pick out parts of the same content. This can result in confusion when terms are used at different levels of analysis.

In the Sociology of Knowledge? post, I complained about a naive, unproblematic distinction between mind and world, then went on to speak of an asymmetric mutual determination. The latter sort of language might standardly be taken to imply a relation between distinct things, contradicting the former language. However, in context, the latter phrase is intended to be anaphoric at a higher level. In this case, mutual determination and the lack of an unproblematic distinction are two ways of talking about the same state of affairs.

This sort of mixed-metaphor-like phenomenon leading to apparent literal inconsistency often crops up when different dialectical levels are mentioned. We have to choose between potentially cumbersome formal disambiguation and extra interpretive work. (See also Aristotelian Dialectic.)

Ontology

Ontology as a supposed science of being acquired its basic shape in the middle ages, as a sort of reification of Aristotelian semantics. Duns Scotus was very proud of his ontological “improvement” of Aristotle. Aristotle himself preferred to shift clumsy, sterile discussions of sheer being onto more subtle and fruitful registers of form and meaning at the earliest opportunity.

Kant pointed out that existence is not a property, and Hegel pointed out the equivalence of Being to Nothing. When Hegel talks about “logic” as the form of future metaphysics, this means a return to the original meaning of “metaphysics” as Aristotelian dialectical semantics, not an ontologization of dialectic. Broadly Aristotelian dialectical semantics give us all the “ontology” we will ever need.

For the historical back story of how Scotus invented ontology as we know it today, if you read French, see Olivier Boulnois, Être et représentation: Une généalogie de la métaphysique moderne à l’époque de Duns Scot (XIIIe–XIVe siècle). As suggested by the title, this work also has extremely important things to say about the premodern history of strongly representationalist views. The famous univocal “being” invented by Scotus was defined in terms of representability. (See also Being, Existence; Aristotelian Dialectic; Objectivity of Objects; Form; Repraesentatio.)

Weak Nature Alone

Adrian Johnston’s latest, A Weak Nature Alone (volume 2 of Prolegomena to Any Future Materialism) aims among other things at forging an alliance with John McDowell’s empiricist Hegelianism, and gives positive mention to McDowell’s use of the Aristotelian concept of second nature. Johnston is the leading American exponent of Slavoj Žižek’s Lacanian Hegelian provocations, and a neuroscience enthusiast. He wants to promote a weak naturalism that would nonetheless be directly grounded in empirical neuroscience. He claims neuroscience already by itself directly undoes “bald” naturalist philosophy from within natural-scientific practice. That sounds like a logical confusion between very different discursive domains, but I am quite interested in a second-nature reading of Hegel.

Broadly speaking, the idea of a weak naturalism sounds good to me. I distinguish between what I think of as relaxed naturalisms and realisms of an Aristotelian sort that explicitly make a place for second nature and assume no Givenness, and what I might privately call “obsessive-compulsive” naturalisms and realisms that build in overly strong claims of univocal causality and epistemological foundations.

Johnston likes McDowell’s rejection of the coherentism of Donald Davidson. McDowell’s basic idea is that coherence can only be a subjective “frictionless spinning in a void”, and that it thus rules out a realism he wants to hold onto. I enjoyed McDowell’s use of Hegel and Aristotle, but thought the argument against Davidson the weakest part of the book when I read Mind and World. If you circularly assume that coherentism must be incompatible with realism, as McDowell tacitly does, then his conclusion follows; otherwise, it doesn’t.

Nothing actually justifies the characterization of coherence as frictionless spinning. This would apply to something like Kantian thought, if it were deprived of all intuition, which for Kant is never the case. Kant sharply distinguishes intuition from thought or any other epistemic function, but nonetheless insists that real experience is always a hylomorphic intertwining of thought and intuition. Brandom brilliantly explains Kantian intuition’s fundamental role in the progressive recognition of and recovery from error, which — along with the recursively unfolding reciprocity of mutual recognition — is essential to the constitution of objectivity.

I want to tendentiously say that as far back as Plato’s account of Socrates’ talk about his daimon, intuition among good philosophers has played a merely negative and hence nonepistemic role. (By “merely” negative, I mean it involves negation in the indeterminate or “infinite” sense, which in contrast to Hegelian inferential determinate negation could never be sufficient to ground knowledge.) On the other hand, that merely negative role of intuition has extreme practical importance.

The progressive improvement of (the coherence of) a unity of apperception that is essential to the distinction of reality from appearance is largely driven by noncognitive mere intuition of error. Intuitions of error or incongruity explicitly bring something like McDowell’s “friction” into the mix.

Charles Pierce reputedly referred to the hand of the sheriff on one’s shoulder as a sign of reality. Like an intuition of error, this is not any kind of positive knowledge, just an occasion for an awareness of limitation. It is just the world pushing back at us.

According to Johnston, McDowell stresses “the non-coherentist, non-inferentialist realism entailed by the objective side of Hegel’s absolute idealism” (p.274). Johnston wants to put results of empirical neuroscience here, as some kind of actual knowledge. But there could be no knowledge apart from some larger coherence, and we are clearly talking past one another. Neuroscience is indeed rich with philosophical implications, but only a practice of philosophy can develop these. (See also Radical Empiricism?)

Johnston wants to revive the Hegelian philosophy of nature. Very broadly speaking, I read the latter as a sort of Aristotelian semantic approach to nature that was also actually well-informed by early 19th century science. I could agree with Johnston that the philosophy of nature should probably get more attention, but still find it among the least appealing of Hegelian texts, and of less continuing relevance than, say, Aristotle’s Physics.

Johnston also likes Friedrich Engels’ Dialectics of Nature. In this case, I actually get more takeaway from Engels than from Hegel. Engels was not a real philosopher, but he was well-read and thoughtful, and a brilliant essayist and popularizer. His lively and tentative sketches were ossified into dogma by others. He did tend to objectify dialectic as happening in the world rather than in language, where I think Plato, Aristotle, and Hegel all located it.

But “dialectic” for Engels mainly entails just a primacy of process; a primacy of relations over things; and a recognition that apparent polar opposites are contextual, fluid, and reciprocal. However distant from the more precise use of dialectic in Aristotle and Hegel, these extremely general principles seem unobjectionable. (The old Maoist “One divides into Two” line, explicitly defended by Badiou and implicitly supported by Žižek and Johnston, not only completely reverses Engels on the last point, but also reverses Hegel’s strong programmatic concern to replace “infinite” negation with determinate negation.)

Engels did infelicitously speak of dialectical “laws” governing events, but his actual examples were harmless qualitative descriptions of very general phenomena. Much of 19th century science outside of physics and chemistry was similarly loose in its application of exact-sounding terms. In Anti-Dühring, however, Engels argued explicitly that Marx never intended to derive any event from a dialectical “law”, but only to apply such “laws” in retrospective interpretation. The “dialectics of nature” is another exercise in Aristotelian semantics. (See also Aristotelian Matter; Efficient Cause.)

It sounds like Johnston wants ontologized dialectical laws of nature, and will want to say they are confirmed by neuroscience results. Johnston also highlights incompatibilities between Brandom and McDowell that are somewhat hidden by their mutual politeness. This in itself is clarifying. I now realize McDowell is further away than I thought, in spite of his nice Aristotelian references. (See also Johnston’s Pippin.)

Aristotelian Dialectic

It was no sophomoric error when Friedrich Engels described Aristotle — not Plato or some neoplatonist — as the greatest dialectician of the ancient world. Aristotelian “dialectic” is just cumulative, exploratory discursive reasoning about concrete meanings in the absence of initial certainty.

Broad usage of the term “dialectic” includes meanings of both dialogue and logic. For Plato, dialogue aimed directly at truth (though not necessarily reaching it). Aristotle considered a many-sided logical/semantic analysis to be the single most important tool of science, and to be more rigorous than the dialogue that was Plato’s favorite literary device.

For Aristotle, unlike Plato, dialectic is not a direct quest for truth. Plato had already emphasized that dialectic is a matter of an ethically motivated quest for truth rather than a claim to mastery or simple possession of it. Aristotle opened things up further by preferring an indirect, semantically oriented approach to the quest. Dialectic ends up being his main critical tool.

Aristotelian dialectic is a semantic and pragmatic inferential examination of opinion or what is merely said (or analogously, I would argue, of appearance). It uses the same logical forms as the rational knowledge Aristotle called episteme; but unlike the latter, yields results that Aristotle calls only “probable”, because they depend on premises that are merely “said” rather than rationally known. (This is a qualitative assessment having nothing to do with statistical probability.)

This has often been taken as a denigration of dialectic. I take it instead as Aristotle’s affirmation of the importance of semantics and pragmatics.

Because dialectic for Aristotle makes no assumptions about what is really true, it is perfectly suited for the examination of arguments for their purely inferential structure. Because it examines concrete arguments with concrete terms, the role of material as well as formal inference can be considered. (See also Inferential Semantics.)

Aristotle also says (Topics Book 1) that dialectic in just this sense is the best means we have for getting clarity about first principles. This is a good example of Aristotle’s inferentialism. Aristotle’s own approach to what later came to be called “metaphysics” is (“merely”) dialectical in this specific sense. In being so, it is essentially semantic and normative. I don’t think Aristotle regarded metaphysics as episteme (“science”) any more than he regarded ethics or phronesis (“practical judgment”) as episteme, and in neither case is it a denigration. (Aristotle is far more honest than most later writers about the relatively less certain nature of so-called first principles, compared with many other apparently more derivative results. He is the original antifoundationalist. See also Dialectic Bootstraps Itself; Demonstrative “Science”?; Abstract and Concrete.)

Hegel actually said the greatest example of ancient dialectic was the commentary on Plato’s Parmenides by neoplatonist Proclus (412 – 485 CE). (He did not know the work of the other great late Neoplatonist, Damascius (458 – 538), which included an even more sophisticated development along similar lines.) The Parmenides explicitly examines a series of antithetical propositions, which does resemble the common image of Hegelian dialectic. (See The One?) In any case, I think this is misleading.

While at least the common image of Hegelian dialectic as concerned with antitheses does not apply well to Aristotle, very fruitful clarifications of Hegel can be obtained by looking out for his use of Aristotelian-style dialectic, despite that fact he — general enthusiasm for Aristotle notwithstanding — did not much mention Aristotle when expounding his own version. Underlying the occasional emphasis on antitheses in Hegel is a broader concern for actually many-sided inferential/semantic examination of opinion or appearance, which is just what Aristotle’s dialectic does. (See also Aristotelian and Hegelian Dialectic; Three Logical Moments; Contradiction vs Polarity.)

My own candidate for the greatest example of ancient dialectic is the development of the concepts of ousia (“what it was to have been” a thing) and energeia (“at-work-ness”) in the central books of Aristotle’s Metaphysics. As in the biological works, merely binary distinction is not the main point there.

The stereotype of a binary schematism at work in Hegel is not without basis, but more careful commentary has limited its scope. Aristotelian dialectic actually pervades Hegel’s works.

In a dialectical development (Aristotelian or Hegelian), it is common to begin with one presumed meaning for a term, and end up with a different one. The classic discussion in the Metaphysics mentioned above begins with the idea of a simple substrate that remains constant through a change, and goes through multiple transformations to progressively richer concepts. (See also Form, Substance; Aristotelian Demonstration.)
