Realism, Nominalism, Modality

There is an important intersection between the 14th century debate about realism and nominalism and contemporary questions about the status of modality in logic that ought to be of interest to non-specialists. Both of these topics probably sound obscure to most people. At sound-byte level, the first is about the status of universals, and modality is something we implicitly presuppose any time we try to reach for something “more” than allegedly pure phenomena or mere appearance.

Both sides of the medieval debate often wanted to enlist the support of Aristotle, who took a remarkably even-handed approach to these questions we have yet to clarify. The debate was often invested with a great moral significance, and provoked a number of intemperate claims. But at the same time, both sides were able to use the technical vocabulary of the theory of “supposition” — along with shared familiarity with Aristotle — to discuss semantic issues of concrete meaning and word use in detail, in terms both sides could in large measure agree upon. This led to a very high quality and sophistication in many contributions to the debate on both sides.

On some slight acquaintance, many modern readers can easily sympathize with nominalist critiques of the premature and illegitimate use of universals. We may think of vulgar platonism, excessive abstraction, reification, alienation, and so on. On the other side though, there are premature and illegitimate claims that universals can be explained away entirely. But Hegel’s Frau Bauer could not even recognize her individually named cows, if there were no such thing as legitimately reusable reference, naming, and vocabulary. I think most people should be able to see that there are two sides to the coin here.

If we ask how legitimate repeatabilities in ordinary language are constituted and used, something like modality inevitably comes into play. It now occurs to me that Brandom’s emphasis on the priority of hypotheticals over alleged categoricals in real-world material inference — a point to which I am deeply sympathetic — really calls for something like the notion of modality that he develops.

Pragmatics of Inquiry

The third chapter of Brandom’s 1976 dissertation addresses a dispute in 20th-century philosophy of science between “realism” and “instrumentalism”. He aims to overcome this dichotomy with the help of concepts developed by John Dewey (1859-1952). Besides its intrinsic interest, the discussion sheds additional light on several terms that are prominent in Brandom’s later work.

“Within the structure of classical (positivist) philosophy of science there was a genuine and easily formulable issue between realists and instrumentalists concerning the nature of scientific theories. Both parties agreed that statements reporting observations are either true or false, and that the terms used in true observational statements refer to actual objects and properties. The realist claimed that theoretical statements are also true or false, and that if true their terms refer to actual objects and properties. The instrumentalist regarded theoretical statements as convenient codifications of inferential practices concerning observational statements. Theoretical statements are rather to be read as expressing rules for complicated practices of material inference. The origin of this suggestion for reading putative propositions as rules for inferential practices lies in the fact that in a formal logical system one can in general replace any premise such as ‘n is an A‘ with material inferential rules of the form ‘From “All As are Bs” infer “n is a B” ‘ ” (Brandom, “Practice and Object”, p. 71).

Here Brandom already makes use of Sellars’ notion of material inference, which is the foundation of the “inferentialism” that will be propounded in his first big book Making It Explicit (1994). Within the current chapter, he approaches realism and instrumentalism in an even-handed manner, but his references to this discussion elsewhere in this work are slanted in the direction of criticizing instrumentalism. Given that his later inferentialism advocates something closely related to what he criticizes here, it is clear that his thinking on this matter has evolved.

In the current context, “realism” refers not to a direct or naive realism (the idea that we directly interact with objectively real things, which are more or less as we take them to be), but to a commitment to the reality of theoretical objects. Alongside this he implicitly portrays both parties to the dispute as holding to a kind of empiricism that he does not criticize here, but does criticize in his later works.

“Beginning with Pierce, the primary motivation for wanting to eliminate commitment to theoretical objects has been a desire to accommodate the sort of open-ended conceptual change which has characterized scientific inquiry from the beginning…. Appreciation of this sort of conceptual change has taken the form of a regulative principle to the effect that there are to be no claims taken as ‘fixed points’ settled once and for all…. This is referred to by Pierce and Popper as ‘fallibilism’, and by Quine as the ‘revisability in principle’ of our beliefs and the concepts they are couched in” (pp. 71-72).

I hold in addition that this “revisability in principle” applies not only to scientific concepts and theories, but also to the concepts and beliefs that we apply in ordinary life and in any kind of dialogue.

“The realists argue that theoretical statements do not simply license certain inferential moves concerning observation statements, they also explain the efficacy and account for the legitimacy of those practices…. Appreciation of the need for some explanation of the sort the realists seek takes the form of a regulative principle for theories of inquiry which Quine calls ‘naturalized epistemology’. It is just the requirement that we be able to exhibit scientific inquiries as natural processes susceptible of ordinary empirical investigation and explanation” (p. 73).

The terms “empirical” and “naturalized” can also have broader meanings than they generally do in modern science. For example, I’ve had a lifelong interest in why people believe the things that they do. In this context it is hard to see any kind of dichotomy between justification and explanation. I approach both in terms of “reasons why”. The explanation at issue here, though, is more narrowly causal in a modern sense. (I take both naturalism and “empirical” inquiry in broader, more relaxed senses — empirical as meaning grounded in ordinary experience, and naturalism simply as not appealing to the supernatural as an unexplained explainer.)

“The classical theory/observation distinction simply repeats the Kantian picture of knowledge as the product of a faculty of receptivity (intuition, observation, the passive appropriation of the ‘given’) and a faculty of spontaneity (understanding, theory, the interpretation of the ‘given’)” (pp. 74-75).

More to the point, the common theory/observation distinction in early 20th-century philosophy of science reflects a common dogmatic attachment to empiricism. But at this early point, Brandom still seems to follow Rorty’s negative view of Kant, and he avoids directly criticizing empiricism. But since Kant emphasizes the interdependence of intuition and understanding and says we never find one of these without the other in any real case, it hardly seems fair to treat this as a rigid dualism. In later works, Brandom treats Kant much more sympathetically, and does directly criticize empiricism.

“It is important to realize that the original dispute proceeded as a disagreement about the nature of theories in which the objects immediately given in observation were taken as the measure against which ‘theoretical objects’ were to be laid…. The notion of a theory-neutral, interpretation-free observation language was attacked by Wittgenstein in the Investigations and by Sellars among others, and had fallen into disrepute in the philosophy of science by the 1960s” (p. 75).

That is once again to say that a kind of dogmatic empiricism reigned almost undisputed in early 20th-century philosophy of science. Within analytic philosophy, this commitment to empiricism only began to be questioned in the 1950s, with the work of late Wittgenstein, Sellars, and Quine.

“[T]he current [1976] situation may be put as follows. In the light of many recent criticisms, philosophers of science have denied that there are sharp differences of kind between objects of observation and objects of theory. Contemporary instrumentalists ([such as] Quine, Feyerabend, and Kuhn) may be thought of as taking this work as … showing that [observation] is more like theory as classically conceived than we had previously thought. So observation is to join theory as a matter of holistically criticizable practices. Realists (such as Putnam, Field, and Boyd) have taken the demise of [the observation/theory distinction] as illuminating our notion of theory, letting us see that theoretical objects are as real, causally efficacious, and independent of our knowledge of them as the classical observable objects” (pp. 76-77).

Each of these latter views seems to make a good point.

“It is not clear, however, … that the new positions are incompatible…. I believe that this is precisely the virtue of Dewey’s theory of inquiry” (p. 78). “Dewey’s idiosyncratic and often obscure account of the mechanics of inquiry … exhibits the realist/instrumentalist dispute as a confusion based on insufficient appreciation of the consequences of abandoning the theory/observation distinction” (p. 70).

He goes on to discuss a number of passages from Dewey. Dewey’s “inquiry into inquiry” is grounded in a specialized notion of situation.

Dewey says “The situation as such is not and cannot be stated or made explicit… It is present throughout [inquiry] as that of which whatever is explicitly stated or propounded is a distinction” (p. 79).

Certainly we never have unqualified “mastery” of our practical or epistemic circumstances, but this doctrine of inherently ineffable “situations” goes further than is needed to make that point. What Dewey says here resembles existentialist claims that existence is ineffable in principle. I was unaware that there was such a dimension to his thought. To my knowledge, none of Brandom’s later works builds on this Deweyan theory of situations. But the way Brandom relates this dubious notion to the making of distinctions puts it in a maximally positive light.

Brandom comments “To ‘know’ something, rather than simply ‘having’ the situation is a matter of repeatables ‘instituted’ within an unrepeatable situation. It is this process which we must investigate to understand the nature of inquiry…. What is excluded by the unrepeatable, non-cognitive nature of situations is only that in a given inquiry I should come to know, rather than simply have, the situation which is the context of that very inquiry. I may investigate other inquiries and their contexts, and this is what one must do to produce a theory of inquiry” (p. 80).

The positive idea that universals arise out of our practices that institute “repeatables” is provocative. No human inquiry partakes of perfect reflexivity, but inquiry is possible nonethless.

“From this external point of view situations are sub-types of the natural occurrences which Dewey calls various ‘histories’ or ‘affairs’. These are the basic elements for which our collective name is ‘nature’ ” (ibid).

He quotes Dewey: “[N]ature is an affair of affairs” (ibid).

Then he goes on: “Situations are a class of affairs which contain sentient organisms. These are the most complicated and interesting affairs in nature, for it is within them that cognition occurs. The model of this sort of affair is the transaction between an organism and its environment in which ‘integration is more fundamental than is the distinction designated by interaction of organism and environment’. The environment here is not just that bit of the physical world which happens to surround the organism. It is that part of the surrounding world with which the organism interacts to live. So from the outside, situations are just congeries of objects ‘falling within boundaries’ determined in some way by the inquirer, and considered as unique, datable occurrences.”

I guess this predates the sentience/sapience distinction that Brandom dwells on in Making It Explicit.

“But if situations are thus unrepeatable constellations of objects, how are the repeatables crucial to cognitive inquiry, as Dewey says, ‘instituted’ within them?” (p. 81).

That is indeed the question.

He quotes Dewey again: “A starting point for further discussion is found in the fact that verbal expressions which designate activities are not marked by the distinction between ‘singular’ (proper) names and ‘common’ names which is required in the case of nouns. For what is designated by a verb is a way of changing and/or acting. A way, manner, mode of change and activity is constant or uniform. It persists through the singular deed done or the change taking place is unique” (ibid).

Adverbial ways of being and ways of acting are far more interesting than mere attributions of undifferentiated existence or action. The association of these adverbial “ways” with a formal characteristic of verbs that is agnostic to the distinction between particulars and universals is unfamiliar and intriguing.

Brandom notes, “Practices, modes of activity involving the objects making up the situation, are to be the basis for repeatability in inquiry” (p. 82)

Now he says it more categorically. Universals become instituted through commonalities in practice, rather than through putative resemblances in perceptual experience. No universal is simply passively acquired.

He quotes Dewey again: “We are brought to the conclusion that it is modes of response which are the ground of generality of logical form, not existential immediate qualities of what is responded to…. ‘Similarity’ is the product of assimilating different things with respect to their functional value in inference and reasoning” (p. 82).

This resembles Brandom’s later critique of assumptions about resemblance.

Brandom comments, “Dewey wants to be able to present a ‘naturalized epistemology’, a theory of inquiry which will account for the practices of an inquirer in the ordinary empirical way, in terms of a set of objects existing antecedent to any activity of the inquirer, and which causally condition his behavior in explicable ways. One of the terms by means of which Dewey formulates the results of his ‘inquiry into inquiry’ is thus the situation. The situation of any particular inquiry we choose to investigate may well contain objects unknown to the inquirer who ‘has’ the situation…. With this introduction to the notion of a situation, we are prepared to approach Dewey’s notion of inquiry” (pp. 83-84).

The way he uses “empirical” here seems to straddle the boundary between empirical science on the one hand, and ordinary experience and natural language use on the other.

“[Dewey’s] official definition of inquiry is: ‘the controlled or directed transformation of an indeterminate situation into one that is so determinate in its constituent distinctions and relations as to convert the elements of the original situation into a unified whole.’ Dewey later decided that this was ill-put, and his considered view is that ‘the original indeterminate situation and the eventual resolved one are precisely initial and terminal stages of one and the same existential situation’. We will see that the ‘transformation’ which is inquiry according to Dewey is a transformation of practices of reporting, inferring, eating, etc. Dewey’s talk of ‘existentially transforming’ situations by inquiring will seem less paradoxical if we recall that the paradigm of a situation from the external point of view is an organism in its environment” (pp. 84-85).

Inquiry is something existentially transforming that occurs within a broadly natural context.

“By insisting on the role of pre-cognitive situations in inquiry, Dewey enforces the constraint of practices and changes of practice by causal relations of pre-existing objects which make those practices possible” (p. 85).

Here Brandom aims to show that Dewey addresses the concerns of the realists.

An interesting sentence in one of his quotations from Dewey is that “The attitude, when made explicit, is an idea or conceptual meaning” (p. 87). The phrase “making explicit” appears here at several important junctures in this discussion of Dewey. The title of Making It Explicit may reflect a Deweyan inspiration. This also sheds light on Brandom’s later talk about the attitude-dependence of normative statuses. The attitudes in question are not purely or shallowly subjective. They are practical stances in situations, subject to concrete give-and-take in the situations, and therefore to objective constraints that go into making the situation what it is.

Young Brandom explains, “A situation is indeterminate insofar as it is uncertain what to do in it, what past situation to assimilate it to…. An inquirer enters any situation with a repertoire of practices differentially elicitable by features of that situation…. The situation is determinate or resolved insofar as a concordant set of practices is unambiguously elicited by the situation. Inquiry is the process of producing such settled situations by applying high-order practices of criticism and refinement of initially conflicting claims made in accord with established practices whether inferential or non-inferential” (ibid).

The notion of a differentiating elicitation does occur in his later work.

“For Dewey, as for Pierce, inquiry is a matter of refining one’s practices toward an ideal in which no situation would elicit discordant or ambiguous activity in accord with those practices. Every time a problematic situation does arise, a re-assessment of the practices involved is required, an adjustment and refinement of that set of practices until concord is reached in the concrete situation” (p. 89).

Brandom’s later works express this repeated re-assessment in terms of the ongoing re-constitution of Kantian unities of apperception. Pierce and Dewey apparently put too much stock in a sort of universal movement toward consensus.

“It is important to this picture of inquiry that the inquirer and the habits which determine his practices are part of the situation. This means that altering one’s practices is a way of transforming one situation into another” (pp. 89-90).

“The essential feature of language is that ‘it compels one individual to take the standpoint of other individuals and to see and inquire from a standpoint that is not strictly personal but is common to them as participants or “parties” in some conjoint undertaking’ ” (p. 90).

Language in part presupposes and in part constitutes intersubjectivity. (Intersubjectivity is not something added onto individual subjectivity, but rather a precondition for its possibility. We could not be talking animals at all without others to talk with.)

“Common sense inquiries and scientific inquiries are alike, in that the same general description as ‘controlled transformation of problematic situations into resolved ones’ applies to both. They are different in that the practices of scientific inquiry are developed, inculcated, and criticized in social institutions unparalleled in the extra-scientific community” (p. 91).

I would say that any serious inquiry is an instance of what Habermas calls communicative action, and involves many considerations that do not apply to action in general.

“By looking thus from the outside at an inquirer and his situation in terms of the best scientific theory we have of them, we can also in principle describe conceptual change in an ordinary empirical way” (p. 93). “By describing their practices with respect to the objects which our best theories tell us make up their situations, we provide the framework for an ordinary empirical investigation of inquiry and conceptual change in terms of the physiological and sociological basis of their practices…. According to Dewey, the activity of the physiologist and sociologist investigating the basis in relation of objects for the practices of various groups of inquirers is itself to be thought of as a set of practices which occur within some non-cognitive situation (had but not known) and transformed as inquiry progresses. Inquiry into inquiry shares with all other inquiries the utilization and adaptation of practices forged in previous inquiries, and hence the revisability-in-principle of all these practices and the claims made in accordance with them” (p. 94).

This seems to treat natural-scientific explanation rather than discursive inquiry into meaning as the paradigm for explanation in general. As evinced by the work of Habermas, revisability in principle is an attribute of discursive or dialogical inquiry in general.

“It should be clear at this point that the realist’s claims and the instrumentalist’s claims as they appear in Dewey’s view of inquiry are completely compatible. Objects and practices occupy correlative functional roles in describing inquiry. Conceptual change is indeed viewed as a change of practice, but neither the practices nor the change is viewed as inexplicable” (pp. 95-96).

This is the main point that young Brandom wants to make here. Issues with classical pragmatist sources notwithstanding, I think he is basically successful.

“On the contrary, any practice or change of practice may in principle be explained by appealing to the objects reported, inferred about, or manipulated in any of the practices which are not then in question. This does not mean that there is any practice which cannot be explained or changed, and which is somehow a basis for the rest. We simply cannot change or explain all of our practices at once” (p. 96).

Any particular belief or concept we may have is subject to revision. But we doubt one thing in light of other things that are provisionally held constant. In real life no one doubts everything at any given time.

“There is a certain sort of circularity here, but it is the familiar non-vicious circularity of any self-regulating enterprise, a formal characteristic acknowledged by contemporary philosophy of science as applying to empirical inquiries, capsulized most vividly in Neurath’s famous figure of a ship making repairs at sea” (ibid).

This idea of practical mutual dependence among the elements of inquiry makes foundationalism untenable.

“The difficulty with the instrumentalists is that, having noticed the problems resulting from an ontology of objects, they sought to put epistemology on a firm footing by substituting an ontology of practices, claiming that objects were derivative entities, ultimately reducible to practices which, as we say, involve them…. Dewey teaches us that the problem is with the notion of ontology itself. Once we have become naturalistic, accepting a thoroughgoing fallibilism means eschewing the notion of a categorization of the kinds of things there are which is outside of and prior to any empirical investigation. Objects and practices are mutually dependent functional notions. We cannot account for the changing roles objects play in our conceptual economy without appealing to practices as well, and we cannot individuate practices without reference to objects” (p. 96n).

Objects are derivative entities, and there is a problem with ontology itself, whether it be taken merely as an a priori enumeration of kinds of things, or as something supposedly more fundamental.

“The problem which faced the realists, as we have argued, is allowing for fallibilism in their account of scientific activity. On the face of it, the explanation which the realist wants to be able to offer of the success of current practices, in terms of the actual existence and causal efficacy of the objects purportedly referred to in the theory will not explain why previous views which we have good empirical reason to believe false worked as well as they did. Nor is it obvious how believing in all those unreal objects enabled us to reach our present privileged position of believing in real ones (i.e., the ones which ‘really’ enable us to engage in the practices we do). Finally, fallibilism dictates that we be willing to accept the possibility of revisions in our current view as radical as those which have occurred in the past” (p. 97).

Here there is a clear parallel to the entry conditions for dialogue developed by Gadamer and Habermas. These apply not only to scientific discourse, but to discourse in general.

“According to Dewey’s view, each time our scientific view of things changes sufficiently, we will have to rewrite our account of the history of inquiry in terms of the sorts of objects which we have new practices of making claims about. But this fact no more impugns the project of explaining how previous practices worked as well as they did, than it impugns any other empirical project which may have to be rethought in view of the results of subsequent inquiry” (p. 98).

Naive views of the history of scientific progress as a linear accumulation toward presumed present truth cannot be sustained. When one view supersedes another in any context, it is not a simple matter of truth versus error. For example, geocentric astronomy had an important practical use in navigation that was not negated by the greater “truth” of heliocentric astronomy.

“As long as knowledge is thought of on the Kantian model, as the product of the collaboration of a faculty of receptivity and a faculty of spontaneity (and the observation/theory distinction is a straightforward version of this model, it will seem that there is a philosophical task of explaining the relations of these faculties. (Even Quine falls into this view in the very midst of a recommendation of a Deweyan naturalism about knowledge.) On this picture, philosophers are to tell us how theory relates to evidence, concept to intuition, in every possible cognition. This project stands outside of and prior to any empirical investigation. Dewey, having wrestled free of the picture generating the classical epistemological project, is able to present inquiry into inquiry as an ordinary empirical matter…. Thus Dewey’s naturalized account of inquiry can retain a distinction between inferential and noninferential practices, and between repeatable and non-repeatable elements. These categories are now meant to have only the same force that any empirical classification has, however. They can be discarded when an empirically better idea comes along. Once we give up the receptivity/spontaneity distinction, and with it the project of a philosophical discipline called ‘epistemology’ which is to relate the operations of the two faculties, we lose also the means to formulate a dispute between realism and instrumentalism concerning which faculty is to be given pride of place” (pp. 98-100).

As I noted earlier, in later works Brandom never blames Kant for the bad idea that there is such a thing as pure observation without any interpretation. That is an empiricist prejudice that ought in fact to be regarded as decisively refuted by Kant. Broadly construed, “naturalism about knowledge” is a good thing, provided it does not lead us back to empiricism.

Next in this series: Truth and Assertibility

Hegelian Semantics

Brandom begins his second Brentano lecture saying, “On the ground floor of Hegel’s intellectual edifice stands his non-psychological conception of the conceptual. This is the idea that to be conceptually contentful is to stand in relations of material incompatibility and consequence (his “determinate negation” and “mediation”) to other such contentful items. The relations of incompatibility and consequence are denominated “material” to indicate that they articulate the contents rather than form of what stands in those relations. This is his first and most basic semantic idea: an understanding of conceptual content in terms of modally robust relations of exclusion and inclusion” (p. 39).

I think Aristotle and even Plato would have agreed with all of this: both the nonpsychological nature of concepts and the fundamental role of modally robust relations of exclusion and inclusion in determining meaning. But the Latin medieval to European early modern mainstream was in this regard much more influenced by the Stoic explanation of meaning by representation, and by the “psychological” cast of Augustine’s thought.

Brandom goes on to characterize Hegel’s position as a “bimodal hylomorphic conceptual realism”, carefully unpacking each part of this dense formula. The two modalities in question are the two fundamental ways in which things have grip on us: the “bite” of reality and the moral “ought”. Brandom holds that there is a deep structural parallel or isomorphism between these two kinds of constraints that affect us. Further, the isomorphism is also a hylomorphism in the sense that the two modalities are not only structurally similar, but so deeply intertwined in practice as to be only analytically distinguishable. Concepts and normativity are interdependent. Finally, it is through concepts and normativity that all our notions of the solidity of reality are articulated.

This kind of conceptual realism in Hegel is complemented by what Brandom calls a conceptual idealism. “At the grossest level of structure, the objective realm of being is articulated by nomological relations, and the subjective realm of thought is articulated by norm-governed processes, activities or practices. It can be asked how things stand with the intentional nexus between these realms. Should it be construed in relational or practical-processual terms?” (p. 43). “Hegel takes there to be an explanatory asymmetry in that the semantic relations between those discursive practices and the objective relations they know about and exploit practically are instituted by the discursive practices that both articulate the subjective realm of thought and establish its relations to the objective realm of being. This asymmetry claim privileging specifically recollective discursive practices over semantic relations in understanding the intentional nexus between subjectivity and objectivity is the thesis of conceptual idealism.” (p. 44).

Plato had talked about recollection in a mythical or poetic way in relation to paradoxes of learning. Hegel’s more “historiographical” recollection is also related to a kind of learning, but Hegel specifically stresses the importance of error as the stimulus to learning. Brandom says there is both a “subjunctive sensitivity of thought to things” (ibid) and a “normative responsibility of thought to fact. What things are for consciousness ought to conform to what things are in themselves.” (p. 45). This translates into a central obligation to repair our errors, and for Hegel the specific way to do this is through a recollective account of what was right in our previous stance; how we came to realize that it went wrong; and what we did to fix it.

“The normative standard of success of intentional agency is set by how things objectively are after an action. The idea of action includes a background structural commitment to the effect that things ought to be as they are intended to be. Conceptual idealism focuses on the fact that all these alethic and normative modal relations are instituted by the recollective activity that is the final phase of the cycle of cognition and action” (ibid).

“Conceptual realism asserts the identity of conceptual content between facts and thoughts of those facts. (Compare Wittgenstein: ‘When we say, and mean, that such-and-such is the case, we—and our meaning—do not stop anywhere short of the fact; but we mean: this—is—so.’ [PI§95]) Conceptual idealism offers a pragmatic account of the practical process by which that semantic-intentional relation between what things are for consciousness and what they are in themselves is established. Pragmatics, as I am using the term, is the study of the use of concepts by subjects engaging in discursive practices. Conceptual idealism asserts a distinctive kind of explanatory priority (a kind of authority) of pragmatics over semantics. For this reason it is a pragmatist semantic explanatory strategy, and its idealism is a pragmatist idealism. The sui generis rational practical activity given pride of explanatory place by this sort of pragmatism is recollection” (pp. 45-46).

Brandom says that Hegel’s notion of experience has two levels, corresponding to two top-level kinds of concepts he distinguishes: ordinary practical and empirical concepts, and meta-level philosophical, categorial or “logical” concepts.

“The master-strategy animating this reading of Hegel (and of Kant) is semantic descent: the idea that the ultimate point of studying these metaconcepts is what their use can teach us about the semantic contentfulness of ground-level concepts, so the best way to understand the categorial metaconcepts is to use them to talk about the use and content of ordinary concepts… The pragmatic metaconcept of the process of experience is first put in play in the Introduction, at the very beginning of [Hegel’s Phenomenology], in the form of the experience of error. It is invoked to explain how the consciousness-constitutive distinction-and-relation between what things are for consciousness and what things are in themselves shows up to consciousness itself. Hegel assumes that, however vaguely understood it might be at the outset, it is a distinction-and-relation that can at least be a topic for us, the readers of the book” (pp. 47-48).

The most naive human awareness already implicitly recognizes a distinction between appearance and reality. “The question is how this crucial distinction already shows up practically for even the most metatheoretically naïve knowing subject. How are we to understand the basic fact that ‘…the difference between the in-itself and the for-itself is already present in the very fact that consciousness knows an object at all’… Hegel traces its origin to the experience of error” (p. 48).

“Hegel finds the roots of this sort of experience in our biological nature as desiring beings…. What a creature practically takes or treats as food, by eating it, can turn out not really to be food, if eating it does not satisfy the hunger that motivated it…. This sort of experience is the basis and practical form of learning” (p. 49). This is “the practical basis for the semantic distinction between representings and representeds, sense and referent” (pp, 49-50).

“[A]n essential part of the acknowledgment of error is practically taking or treating two commitments as incompatible. Such genuinely conceptual activity goes beyond what merely desiring beings engage in. The origins of Hegel’s idea here lie in Kant’s earlier broadly pragmatist account of what knowing subjects must do in order to count as apperceiving” (p. 50).

“Hegel breaks from the Kantian picture by adding a crucial constraint on what counts as successful repairs…. Successful repairs must explain and justify the changes made, in a special way” (p. 52). This takes the form of a historical recollection. “To be entitled to claim that things are as one now takes them to be, one must show how one found out that they are so. Doing that involves explaining what one’s earlier views got right, what they got wrong, and why…. This is the progressive emergence into explicitness, the ever more adequate expression, of what is retrospectively discerned as having been all along implicit as the norm governing and guiding the process by which its appearances arise and pass away” (p. 53). “Recollection… turns a past into a history” (p. 54).

All this serves as an explanation of how we come to have representations that actually refer to something, in terms of how we express our concerns. “In general Hegel thinks we can only understand what is implicit in terms of the expressive process by which it is made explicit. That is a recollective process. The underlying reality is construed as implicit in the sense of being a norm that all along governed the process of its gradual emergence into explicitness” (p. 56).

“Kant had the idea that representation is a normative concept. Something counts as a representing in virtue of being responsible to something else, which counts as represented by it in virtue of exercising authority over the representing by serving as a standard for assessments of its correctness as a representing. It is in precisely this sense that a recollective story treats the commitments it surveys as representings of the content currently treated as factual” (p. 58). Brandom says that Hegel reconstructs in expressive terms what the representationalists were right about, while strongly contrasting this way of thinking with representationalism.

“Hylomorphic conceptual realism then underwrites the idea of the categorial homogeneity of senses as graspable thoughts and their referents (what they represent) as correspondingly conceptually contentful, statable facts. This makes intelligible the idea that thoughts are the explicit expressions of facts. They make explicit… how the world is” (p. 60).

“The plight of finite knowing and acting subjects metaphysically guarantees liability to empirical error and practical failure. The experience of error is inescapable. What I earlier called the ‘false starts, wrong turns, and dead ends’ of inquiry can be retrospectively edited out of the sanitized, Whiggish vindicating recollective narrative, but they cannot be avoided going forward.

“Why not? In short because the rational, conceptual character of the world and its stubborn recalcitrance to mastery by knowledge and agency are equally fundamental primordial features of the way things are” (pp. 61-62).

“For Hegel, the experience of error requires not just the revision of beliefs… but also of meanings” (p. 62). “The manifestation of stubborn, residual immediacy in thought is the inevitability of the experience of error…. [T]he ineluctability of error and the realistic possibility of genuine knowledge [both] express valid perspectives on what is always at once both the experience of error and the way of truth. The important thing is not to seize exclusively—and so one-sidedly—on either aspect, but to understand the nature of the process as one that necessarily shows up from both perspectives” (p. 63).

“One of Hegel’s animating ideas is that the independence of immediacy (its distinctive authority over structures of mediation) is manifested in its role as a principle of instability, as providing a normative demand for change, for both rejection and further development of each constellation of determinate concepts and commitments articulated by them. The independence of mediation (its distinctive authority over immediacy) is manifested in all the retrospective recollective vindications of prior constellations of commitments as genuine knowledge, as resulting from the expressively progressive revelation of reality by prior claims to knowledge.” (pp. 64-65).

“The forward-looking obligation to repair acknowledged incompatibilities of commitment acknowledges error and the inadequacy of its conceptions. The backward-looking recollective obligation to rationalize as expressively progressive previous, now superseded, repairs and recollections institutes knowledge, truth, and determinate concepts whose incompatibilities and consequences track those articulating (in a different modal key) the objective world…. The recollective process is also what Hegel calls ‘giving contingency the form of necessity.'” (p. 65).

“The key in each case is to understand [truth and error] not as properties, states, or relations that can be instantiated at a single time, but as structural features of enduring experiential processes” (p.66).

This is to move from what Hegel calls Understanding to what he calls Reason. Understanding focuses on the fixity of concepts; Reason also has regard for their malleability. To think of experience as asymptotically approaching objective facts and relations belongs to the Understanding that disregards the mutation of meanings.

“The world as it is in itself as distinct from how it is for consciousness is not a brute other, but in that distinctive sense the product of its own recollective activity in experience” (p.72).

Instrumentalism?

In the last post I gave positive mention to an “instrumentalist rather than realist view of scientific explanation”. I think an instrumental view of science is the natural one from an engineering point of view, which the philosophy of science ought to take very seriously. I actually work as an engineer in my day job, and have a bit of engineering education. Though these days I privately think of myself mainly as a moral philosopher, I truly enjoy engineering for its practical orientation. Engineers learn that the real world doesn’t always conform to theoretical simplifications, and they have to make what are actually value judgments all the time.

Curiously, it seems to me that in spite of our culture’s obsession with technology and all the stereotypes about nutty scientists, engineering as a discipline doesn’t have nearly as much social prestige as science. For the reasons just mentioned, I think engineering deserves the higher status, as the actually more comprehensive concern. Modern science is first and foremost a tool used in engineering. But in our culture’s mythology of science, there is a popular prejudice that engineers — unlike real scientists — just make rote applications of formulae developed by scientists. Meanwhile science students — if I may be forgiven a broad-brush picture — all too often seem to get the message that the latest Science is Truth, and everything else is irrelevant. This can unfortunately make them arrogant and dogmatic in later life. I think engineers on the whole are more attuned to the provisional status of assumptions.

On the historiographical side, I think the over-propagandized scientific revolution was actually more of an engineering revolution. The design of experiments can be considered a kind of engineering, as can the development and use of therapeutic techniques in medicine. The very practical, experiment-oriented work of Francis Bacon (1561-1626) in its broad parameters at least is a much better model for science in the modern sense than the new mechanist/voluntarist dualist world view promoted by Descartes, or even the empiricism of Locke. In terms of the long time-scale of human development, engineering long predates science, and I think that generally speaking, historical causality flows that way, with engineering driving science rather than following it.

These varied considerations seem to me to jointly favor an “instrumentalist” view in the philosophy of science. This is another example of the mediated or “long detour” type of approach to knowledge that seems most sound to me.

In analytic philosophy in recent decades, there has been a big debate about realism versus anti-realism. Implicitly, this mainly applies to the philosophy of science, but in many circles there are still prejudices that theory of knowledge comes first in philosophy, and that science is the most important kind of knowledge. This can make it seem as if realist or anti-realist positions in the philosophy of science must be applied across the board at a sort of ontological level, but I want to argue against that.

I think that ethical reason and interpretation come before the theory of knowledge in the overall order of explanation relevant to human life, and that normative practical judgment actually grounds what we think of as exact knowledge. From an ethical standpoint, it is vitally important to recognize there is a “push-back” of reality we need to respect and take into account, so I want to argue for a kind of realism. The true home for a respect for realism, I want to say, should be ethics and not the philosophy of science. We can meet all the ethical needs related to concern for objectivity in a way that is entirely compatible with an instrumentalist and “anti-realist” philosophy of science. Meanwhile, a more modest view of science — as a valuable tool rather than a source of ultimate truth — can help heal the false rift between science and values that permeates our culture. Further, if science is a tool and we also say that higher forms of faith are expressed not in propositions but in action and attitude (as I would respectfully suggest), then in the world of what should be, there is no possibility of conflict from either side. (See also Kinds of Reason.)

Things in Themselves

I never understood why people would object to Kant’s thesis of “things in themselves”, or find it inconsistent with his epistemological scruples. I take this just to mean that there are ways that things are. This is an entirely separate question from whether we have perfect or certain knowledge of those ways. All that is ruled out by Kant’s Critical perspective is claims that we have knowledge of things just as they are in themselves. This just calls for a kind of epistemic modesty. (See also Kantian Discipline; Copernican; Dogmatism and Strife; Transcendental?)

People who rejected things in themselves included Fichte and the important early 20th century English translator and interpreter of Kant, Norman Kemp Smith, who was sympathetic to the phenomenalism then fashionable among empiricists (see brief discussion under Empiricism).

Hegel too was very critical of the phrase “things in themselves”, mainly because he thought the wording implied a kind of artificial isolation, but he by no means wanted to throw out the realist moment that Kant always wanted to affirm — quite the opposite. Discussions about realism and idealism get rather complicated, especially where Kant and Hegel are concerned, but Kant repeatedly affirmed a kind of empirical realism. I take this to have been a sort of pragmatic vindication of common sense with respect to ordinary experience, coupled with respect for Newtonian science. What Kant and Hegel both objected to — each in their own different terms — were strong traditional metaphysical claims. Whatever their other many differences, commentators are basically unanimous in taking Hegel to have wanted to be at least as “realist” as Kant.

Leibniz had suggested that God’s single eternal act is the selection of the best of all possible worlds from all possible worlds, and that in this context the complete essence of a thing is foreseen by God, allowing for a version of particular providence. Even though he worked out an alternative scheme for more concretely relational determination of essences in late correspondence with the Jesuit theologian Bartholomew Des Bosses, Leibniz preferred to stress the predetermination of each individual monad by God, as part of a comprehensive pre-existing harmony that put the reality of relations in the mind of God rather than in the world. In this context, Leibniz also famously suggested that monads do not really interact and “have no windows”. For Leibniz, “windows” to the outside are not really needed, because each monad contains within itself a reflection of the entire universe.

One of Kant’s earliest moves, however — long before publication of the First Critique — was to argue against Leibniz for common-sense real interaction among things in the world. It is doubtful that Kant knew of Leibniz’s alternative scheme for real relations, but in any case, Kant throughout his career stressed immanent relations among things in the world, rather than transcendent relations realized primarily in the mind of God. Since even the pre-Critical Kant had thus already undone the basis for treating each monad in splendid isolation, it seems very unlikely that the Critical Kant meant to imply any strong monadic properties when he spoke of things “in themselves”.

Saying that there are ways that things are does not have to mean that everything is determined down to the last detail. (See Equivocal Determination.)

Nominalist Controversies

Especially in the 14th century, controversies associated with the opposition between nominalism and realism greatly exercised philosophers and theologians in the Latin West. These terms have been been variously understood, but as a first approximation, nominalism wants to deny claims about the real basis of abstractions that the realism of this context wants to affirm.

In this case, a polar opposition is concealed behind a pair of concrete terms (nominalism, realism), where in context one is understood as the simple negation of the other. As usual with debates around distinctions based on polar opposition rather than more limited and definite determinate negation, the greatest interest often lies in the way each side tries to recover something like the strong points of the other side, but in its own terms.

These controversies are worth lingering over for several reasons. For one thing, they help illustrate the great diversity, subtlety, and liveliness of medieval thought. For another, they develop many fine distinctions that are of lasting value in talking about human knowledge and understanding. We would all like to rightly apprehend things, whatever that means. The waters are commonly muddied not only by insufficient distinctions among things, but also by fundamental unclarity or ambiguity on the meaning of “existence” or “reality”, which gets worse where abstract things are involved. Who we might think was right in the debates is of secondary importance compared to clarifications of this kind. Finally, these debates involved much discussion of mental representation, its origins, and its role in thought.

Speaking with very broad brush, nominalism begins as a critique of a sort of “platonism”. Such platonism wants to say the universal is more real than the particular. It may go on to claim that abstract entities are as real as — or more real than — concrete ones. It may extend to further claims that universals simply “exist” in some pure way, independent of space and time. Nominalism in general wants to say the opposite, that universals are actually not real at all.

Aristotle already criticized platonist views of the sort just mentioned, while still maintaining that the development of universals is essential to knowledge. I think that in the big picture, he wanted to recommend an essentially even-handed approach, recognizing both universals and particulars as necessary to any developed view of experience, while pointing out their very different and complementary roles. Whatever we may think about the reality or unreality or existence or nonexistence of given things or of various kinds of things, we need universals to support the implicit reasoning standing behind any developed knowledge. We also need particulars as practical starting points, and as cross-checks to keep us honest. This does not yet make any claim about reality or existence that might support such needs. Aristotle often practiced a careful minimalism, sticking to essentials and leaving other questions open, and this is a good case in point.

Albert the Great and Thomas Aquinas wanted to develop Aristotle’s position into a firmer doctrine, classically called moderate realism. Most people agree that Aristotle thought universals do not “exist” independently of particular things and thought. Albert and Thomas argued that implicitly, what Aristotle said committed him to 1) a claim that universals are real and 2) a claim that universals exist, but only in concrete things and in thought.

Nominalists especially disputed the claim that universals exist in concrete things. They most commonly advocated a mental origin of universals, while differing on the precise status attributed to them. Already in the 12th century, Roscellinus had argued that universals are mere names (root of the word “nominalism”). Whether or not the great Peter Abelard should be interpreted as a nominalist or a middle-of-the road “conceptualist” is contested among scholars.

The theologian William of Occam (1285 – 1347) was the most famous medieval nominalist. Early in his career, he argued that universals were ficta (“fictions”) of the mind. Later, he worried that this still tacitly presupposed they were representations, which would seem to still imply something corresponding to them in external objects. He then argued that external objects have causal impact on the mind, but not by representation.

The important secular master John Buridan (1301 – 1358) is usually also called a nominalist. Buridan was one of the leading logicians of the middle ages, and wrote on a wide range of philosophical questions. He had several noteworthy students who are also considered nominalists, including the logician, natural philosopher, and bishop Albert of Saxony (1320 – 1390). Marsilius of Inghen (1340 – 1396) was another nominalist who wrote on logic, natural philosophy, and theology. The theologian Gregory of Rimini (1300 – 1358) is also considered a nominalist.

The great theologian John Duns Scotus (1265 – 1308) was a commited realist who nonetheless influenced Occam on some relatively unrelated points. The influential Walter Burley (1275 – 1344) is sometimes called an extreme realist. Paul of Venice (1369 – 1429) was formerly classed as a nominalist, but is now considered a realist.

Among those who were called nominalists, there were many different views and distinctions related to the complex medieval theories of sensible and intelligible “species”. In one aspect, these were mental representations, but theories of sensible species usually had a physical component loosely inspired by Stoicism. Occam denied species, while Buridan made use of them.

From the 12th century onward, Latin philosophers developed sophisticated original theories of the different kinds of “supposition”, or generic ways in which something said can be meant. The general notion was that the kind of supposition that should be read into a concrete utterance should be determined by analyzing the context of the utterance in various ways. This was basically a kind of semantics. What is perhaps surprising is that broadly similar supposition theories were largely shared by dedicated nominalists like Occam and commited realists like Walter Burley, providing a common vocabulary.

On a side note, Occam’s causal impact theory seems problematic from the point of view of the development here. While its avoidance of dependence on representation is attractive, a direct causal link from external objects to thoughts does not seem adequate to account for the full range of diversity of thoughts. Also, there seems to be an incipient mentalism already at work here, related to that of Avicenna.

Occam was a theological voluntarist and a fideist. Fideism is the belief that faith offers a kind of knowledge superior to reason, an extreme position that was repeatedly condemned by the Church. Occam has nonetheless often been named as a major precursor of the point of view of modern science. Even though some connections can be made, this seems questionable as well, given his mainly theological intent and the character of the theology he promoted.

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.

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.)
