Parts of the Soul

For Aristotle, psyche or “soul” is an ordinary empirical concept. First and foremost, it names a set of functional characteristics and abilities that distinguish living from nonliving things. Associations with what we might call specifically mental functions are secondary to this. The Stanford Encyclopedia of Philosophy has a good introduction.

When speaking of “parts” of the soul, Aristotle means distinguishable groups of functions. He explicitly leaves open the question whether they are actually separable from one another. Sometimes he seems to distinguish three main parts: one associated with the basic functions of nutrition and reproduction shared by all living things, including plants; one associated with desire and sensorimotor functions, shared by all animals; and one associated with reason and intellect. At other times, he makes finer distinctions.

Perhaps unexpectedly, reason (logos) and intellect (nous) for Aristotle seem to be more sharply distinguished from what we might call mental functions than mental functions are from biological ones. In contrast with, e.g., memory, which he says cannot exist independent of a living body, and in spite of the fact that he thinks thought contents build on sense perception, he explicitly says intellect has no bodily organ and comes from outside. The very closely connected concept of reason is mainly associated with language and the right kind of socialization. I think reason and intellect still get treated as part of the soul mainly because their presence reshapes the whole (See also Reasonableness; Feeling; Second Nature; Intelligence from Outside; Psyche, Subjectivity; Passive Synthesis, Active Sense.)

For animals, including rational animals, Aristotle located the seat of the soul in the heart. In his time, there was as yet no evidence to refute this traditional conception; understanding of the physiological role of the brain and nervous system only developed in later Greek medicine. But recall also that the psyche for Aristotle is at root more vital than mental. Even today, we still distinguish life by a literal heartbeat, and associate emotion figuratively with the heart.

Truth and Judgment

Negative reactions to Brandom are a veritable industry these days. Another one I just encountered, by Karl Hahn, comes from a Thomistic direction, and mainly wants to reassert an incompatible view of truth. This yields a useful delineation.

Humanity owes Thomas Aquinas an immense debt of gratitude for helping end the European dark ages and usher in the high medieval development that led to the Renaissance, by making Aristotle acceptable to the Church. But while I am broadly sympathetic to Aristotelian tendencies in theology, I also think theological “improvements” to Aristotle were not improvements.

Aquinas had a very distinctive and sophisticated view of truth. It was extremely remote, however, from that of Brandom and the one I attribute to Aristotle. Aquinas wanted to combine Aristotelian learning and ethical discourse with Christian revelation and the broadly Augustinian tradition of faith seeking understanding, into one seamless edifice. From this perspective, there are truths of reason, truths of experience, and truths of revelation, but truth must agree with truth, so things must be interpreted in a way adequate to them all.

Hahn, following Alasdair MacIntyre, summarizes the Thomistic view of truth as something said primarily of intellect, rather than of propositions. Aristotle discussed truth in the context of things said, but Plotinus already articulated something like MacIntyre’s view, which apparently puts a kind of immediate synthetic mental apprehension ahead of any extended articulation. Simultaneously, Plotinus contributed to a shift in emphasis from form or concept to something more like what we think of as a subjective “mind”. (I would argue that Aristotle’s own notion of intellect is fundamentally not subjective in the modern sense; see Substance Also Subject.)

When we speak of some understanding as “true”, I take that as a sort of poetic metonymy, not a literal statement. Truth can be derivatively said of an act of understanding, based on judgment of that understanding’s soundness and circumstantial appropriateness, which is to say not only the inferential but also the broader emotional and social reasonableness of its articulable content. Understanding-as-truth could almost be taken to hint at something like Hegelian truth-as-process, except that for Plotinus or Aquinas it is an achieved result that should be valid for all time.

Hahn is wary of “intra-rational” criteria for the evaluation of reasons, relating this to what he calls idealist-pragmatist “relativism”. Such worries about relativism depend on a huge equivocation between views that want to take more distinctions into account, and views that implausibly deny the reality of all distinctions. (For Aristotle as well as Kant, distinctions rather than assertions form the basis for evaluation and determination of content. Responsible, serious assertion is an outcome of evaluation.)

Thomism, while placing high value on reason, is fundamentally at odds with the Kantian autonomy of reason, which is an ethical imperative that evaluation be exclusively “intra-rational”. Here, “rational” means not just narrowly logical, but substantively reasonable.

I see strong textual evidence for anticipation of Kant’s autonomy-of-reason thesis in Plato and Aristotle. While we should respect the opinions of the wise, no opinion or received truth can be the final word. An assertion is just as good as the evaluation on which it is based.

As important as reasoning is for Aquinas, it is ultimately subordinate to a body of received truths, both of revelation and of what he calls natural light. (Along with Duns Scotus, Aquinas was an important precursor of modern doctrines of truth-first representationalism that stand in contrast to Aristotle and Brandom’s reason-first inferentialism.)

My view is that even the most polite, well-intentioned claims of received truth prematurely end the possibility of real dialogue about what is reasonable and good, and that they are in that way opposed to truth in a deeper sense like the Hegelian truth-as-process (or, I would argue, even Platonic truth). Kant called claims of received truth “dogmatism”. Genuinely good insights are diminished by being presented with inappropriate finality. (See also What and Why; Theology; God and the Soul; “Said Of”; Justification; Realism, Idealism; Metaphysical, Nonmetaphysical; Weak Nature Alone; Brandomian Forgiveness.)

Aristotelian Identity

Aristotle’s notion of identity is initially relational or structural, and ultimately processual. I read his emphasis on concrete entities in the Categories as pragmatic rather than ontological, and as of a piece with his general methodological recommendations about starting from what is close to us. Aristotelian starting points normally end up being substantially revised or discarded in the actual carrying out of an inquiry; they are intended just to begin a discussion in an accessible way. In the Metaphysics and the biological works, a nuanced and multi-leveled notion of form is developed that also represents Aristotle’s best thought on what we call identity.

For Aristotle, the identity of a thing at a given moment is almost reducible to what is true of it at that moment, i.e., to its articulable properties. There is no ineffable but contentful remainder underpinning individuality, like a Scotist haeccitas would seem to be.

I say almost reducible because the relational or structural criteria for identity of “this” continuing thing may change substantially over time, either straightforwardly because the thing itself changed, or more subtly because something else changed in the context of evaluation. Aristotle shares Hume’s scruples about applying identity in the first case, and Hegel’s about applying it in the second. Like Hegel but unlike Hume, he is also concerned to articulate and progressively improve criteria for higher-order stability of conceptual articulation in the face of first-order flux. This in a sense re-vindicates most of what is behind the common-sense notion of persisting “things”, provided we avoid overly rigid notions of the identity of those things. (See also Substance; Things Said; Aristotelian Dialectic; Being, Existence; Equivocal Determination.)

Metaphysical, Nonmetaphysical

There is a large current debate over so-called “metaphysical” versus “nonmetaphysical” readings of Hegel. Brandom, Robert Pippin, and Terry Pinkard are considered to be in the nonmetaphysical camp, and my sympathies are generally on this side. I also think that the “metaphysical” camp makes many unwarranted assumptions about what metaphysics must be; and that the so-called nonmetaphysical approach to Hegel is actually much closer to what emerges from an unbiased and historiographically aware close textual reading of Aristotelian metaphysics. (Justification of this obviously large claim is a work in progress, far exceeding the scope of a single post. But see menu for many related notes on Aristotle and Hegel.)

I take the term “metaphysics” to refer in the first instance to concerns addressed in the collection of Aristotelian texts later editors placed “after the Physics”, when physics itself had already been developed in terms of a kind of semantics of the becoming of sensible things. Aristotelian “metaphysics” is dedicated to a further dialectical exploration of higher-order interpretive concepts already employed throughout his works.

Many layers of very non-Aristotelian Neoplatonic and theological interpretation affect the way Aristotelian texts are still commonly read today. To the extent that they relate to Aristotle at all, common connotations of the term “metaphysics” almost exclusively pick out what were actually non-Aristotelian biases in historical readings of Aristotle. Interpretations I refer to as biased in this way were often highly sophisticated and interesting in their own right, but that is not the point here. (See also Ethics vs Metaphysics; Aristotelian Dialectic; Being, Existence; Ontology.)

Beyond Subject-Object

Hegel famously wanted to move beyond the subject-object dichotomy he saw as typical of early modernity. In practical terms, Kant’s most famous concern to avoid “dogmatic” assumptions about direct possession of epistemic objects had seemed to accentuate the separation of subject and object, by focusing on the distinction between appearance and reality. But both Kant and Hegel wanted to assert the possibility of knowledge in a strong sense, while avoiding what Kant called dogmatism. They also had considerable common ground in a shared rejection of naive early modern notions of subjects and objects and their relations.

Kant had begun — seemingly unwittingly — to recover some neglected Aristotelian insights in these areas, and Hegel made this an explicit theme. Thus they both already questioned the dichotomous interpretation of subject-object relations. Kant had also already highlighted the inevitable involvement of concepts in experience. For Kant, there is no direct epistemic access to real-world objects, or things in themselves (or to our own subjectivity). All knowledge proceeds by way of concepts, but he retains the concept of objects (and subjects) as a sort of placeholders for new distinctions between appearance and reality that can always be wrapped around current concepts in a new iteration.

When dichotomous connotations have already been applied to a distinction in some communicative context, it can be tricky to simultaneously clarify the transcendence of the dichotomy and the preservation of the underlying distinction, but the general solution is not far to find — just ensure that the underlying distinction is expressed in terms of some finite relation, rather than A versus not-A. Then we have Hegelian determinate negation or Aristotelian difference between the terms, rather than classical negation. So in effect, the solution lies in recognizing that the previous understanding of the distinction in terms of dichotomy was wrong in the first place.

More positively, Hegel eliminates dichotomies by putting determinate relations, coherence, and mediation first in the order of explanation, before all particular terms. The Hegelian Absolute — or that which transcends the subject-object dichotomy — is just a handle for perspectives that put processes, relations, coherence, and mediation before any preconceived notion of the conceptual content of particular terms.

I think Hegel saw this sort of structure as common to Aristotelian substance or “what it was to have been” a thing on the one hand, and Kantian subjectivity or synthesis of apperception on the other.

Working in the Hegelian Absolute does not require epistemic super powers or specious Cartesian certainty, just a sustained honest effort that is still implicitly defeasible. Hegel intends the Absolute to be a kind of Aristotelian achievable perfection, not a kind of omniscience or theological perfection that could never be legitimately claimed by a rational animal. (See Substance Also Subject.)

In approaching these matters in A Spirit of Trust, Brandom characteristically focuses not directly on higher-order abstractions, but on their implications for what we do with ordinary concepts in ordinary experience. Like Aristotle and Hegel but following a distinct strategy of his own, Brandom avoids the impasse of a supposed transition from psychological to “metaphysical” terms, or from ordinary experience to something that would seemingly have to be like the mind of God, by clarifying what we implicitly mean by concepts in the first place.

With Aristotle, Hegel, and Frege and in contradistinction to the empiricist tradition, Brandom understands concepts and apperception in a nonpsychological, nonrepresentational, normative-pragmatic, inferential-semantic way. Through the discovery of counterfactually robust relations, concepts evolve toward increasing universality. Through the experience of error, synthesis of apperception comes to incorporate the recognition that not only its commitments but also its concepts are always in principle provisional, subject to reformulation when faced with a new case. Through both of these combined with the additional cross-checks provided by mutual recognition, synthesis moves toward increasing objectivity and what might be called contact with reality. Through Brandom’s “expansive” model of responsibility, the last remaining obstacle to a full resolution of subject-object separation — the lack of a normative interpretation of unintended consequences of actions — is removed.

Neither “subjects” nor “objects” as such are very prominent in an account of this sort. It is much more a story about processes, relations, coherence, and mediation. Aristotle, Hegel, and Brandom each develop their own ways of working that start in the middle, as it were, and do not need reified subjects and objects to begin with. This, again, is just what the Hegelian Absolute is — a name for the sort of perspective that emphasizes the in-principle provisional character of all finite concepts, as contrasted with the more directly practical sort of perspective that provisionally works with the current basis as a source of reasons for particular sayings and doings. (See also Aristotelian and Hegelian Dialectic; Contradiction vs Polarity; Three Logical Moments.)

Ethos, Hexis

For Aristotle, character and ethical culture (named respectively by the two related Greek words éthos and ethos) — including what Brandom would call our constellation of commitments and what Hegel would call our self-consciousness — build on hexis. The latter is most commonly translated as habit. Earlier, I called it emotional constitution. It is an acquired, active disposition to respond or act in certain ways that seems to be centered in the emotions. A good hexis is characterized by what we might call emotional intelligence.

Actions, reactions, and choices — as well as many things that just happen to us — cumulatively contribute to the formation of a more long-term emotional constitution that then becomes directly responsible for the tone of our responses to things, and that we can only change with major, prolonged effort, if at all. This, I believe, is the main basis of common-sense personal identity.

People respond to situations based on a combination of emotional disposition (hexis), their constellation of commitments and self-consciousness (ethos), and deliberation and choice. It does not generally make sense to blame someone for acting in accordance with their acquired disposition, but at a broader level, people are partly responsible for the formation of their disposition. People are responsible for their choices, unless they are coerced or misinformed. People are in principle responsible for their commitments; bad commitments usually involve more than simple misinformation. But misinformation, lack of good opportunity for learning, and emotional disposition should certainly be taken into account in charitable interpretation of commitments, too. (See also Willing, Unwilling; Second Nature.)

According to Aristotle, a disposition favoring reasonable emotional responses is a prerequisite to higher ethical development, and this needs to be learned from childhood. (See also Feeling.)

Aristotle and Brandom?

For the second time, I think I discovered a significant new insight into a major Aristotelian concept by thinking it through in Brandomian terms. When I began this effort, Aristotle and Brandom were just the two philosophers with whom I was most engaged, who seemed to me to share my overarching concern with the ethical import of reasons and things said, but it is growing to be something more.

(To some, this might seem a strange pairing. However, in spite of his own lack of direct engagement with Aristotle, Brandom has commented that a number of his best interlocutors (unnamed) were what he called neo-Aristotelians. Certainly, Hegel — the historic philosopher with whom Brandom has been most engaged — makes major use of Aristotle, and Brandom’s co-thinkers on Hegel, Robert Pippin and Terry Pinkard, have highlighted this.)

Earlier, I noted a kind of isomorphism between Aristotelian potentiality and Brandomian modally robust counterfactual inference, which then turned into a three-way correspondence with the structuralist concept of structure, and helped illuminate the old synchronic/diachronic issue associated with structuralism.

The other day, I noted a second isomorphism, between canonical Aristotelian proposition-forming combination and separation and Brandomian material consequence and material incompatibility. The result is that Aristotle’s canonical conception of logical truth seems very consistent with what Brandom recommends, in terms of using goodness of material inference to explain truth rather than using truth to explain inference.

Brandom has referred to this sort of interpretation as a recollective genealogy, grounded in Hegel’s way of retrospectively interpreting past philosophers in light of the present. Obviously there is a creative element to such an endeavor. The important and delicate point is that it not be an arbitrary imposition, but something that yields genuine insight that is both relevant to the present and honestly compatible with the best historiographic objectivity we can fallibly attain. In the two cases mentioned above, I think that has been achieved.

Going in the other direction, developing an Aristotelian interpretation of Brandom’s distinction between sentience and sapience has helped me to achieve full sympathy with this notion, and with several of Kant’s apparently dualistic moments as well.

Somewhat ambidextrously, it seems to me that Brandomian commitments, together with the sort of pattern of performance with respect to responsibility measured by Brandomian deontic scorekeeping, make up the ethical character or culture that Aristotle called ethos. (See also Ethos; Aristotelian Subjectivity; Brandomian Choice.)

Aristotelian Propositions

Every canonical Aristotelian proposition can be interpreted as expressing a judgment of material consequence or material incompatibility. This may seem surprising. First, a bit of background…

At the beginning of On Interpretation, Aristotle says that “falsity and truth have to do with combination and separation” (Ch. 1). On its face, the combination or separation at issue has to do not with propositions but with terms. But it is not quite so simple. The terms in question are canonically “universals” or types or higher-order terms, each of which is therefore convertible with a mentioned proposition that the higher-order term is or is not instantiated or does or does not apply. (We can read, e.g., “human” as the mentioned proposition “x human”.) Thus a canonical Aristotelian proposition is formed by “combining” or “separating” a pair of things that are each interpretable as an implicit proposition in the modern sense.

Propositions in the modern sense are treated as atomic. They are often associated with merely stipulated truth values, and in any case it makes no sense to ask for internal criteria that would help validate or invalidate a modern proposition. But we can always ask whether the combination or separation in a canonical Aristotelian proposition is reasonable for the arguments to which it is applied. Therefore, unlike a proposition in the modern sense, an Aristotelian proposition always implicitly carries with it a suggestion of criteria for its validation.

The only available criteria for critically assessing correctness of such elementary proposition-forming combination or separation are material in the sense that Sellars and Brandom have discussed. A judgment of “combination” in effect just is a judgment of material consequence; a judgment of “separation” in effect just is a judgment of material incompatibility. (This also helps clarify why it is essential to mention both combination and separation affirmatively, since, e.g., “human combines with mortal” canonically means not just that human and mortal are not incompatible, but that if one is said to be human, one is thereby also said to be mortal.)

This means that Aristotle’s concept of the elementary truth and falsity of propositions can be understood as grounded in criteria for goodness of material inference, not some kind of correspondence with naively conceived facts. It also means that every Aristotelian proposition can be understood as expressing a judgment of material consequence or incompatibility, and that truth for Aristotle can therefore be understood as primarily said of good judgments of material consequence or incompatibility. Aristotle thus would seem to anticipate Brandom on truth.

This is the deeper meaning of Aristotle’s statement that a proposition in his sense does not just “say something” but “says something about something”. Such aboutness is not just grammatical, but material-inferential. This is in accordance with Aristotle’s logical uses of “said of”, which would be well explained by giving that a material-inferential interpretation as well.

The principle behind Aristotelian syllogism is a form of composition, formally interpretable as an instance of the composition of mathematical functions, where composition operates on the combination or separation of pairs of terms in each proposition. Aristotelian logic thus combines a kind of material inference in proposition formation and its validation with a kind of formal inference by composition. This is what Kant and Hegel meant by “logic”, apart from their own innovations.

Abstraction

Abstraction in Aristotle is sometimes made out to be mysterious. I think it is just straightforward subtraction of features of a thing that have been previously recognized as “accidental” for the pertinent context of evaluation. Abstraction is neither a way of magically laying bare the true inner essence of a thing, as envisioned by some medieval realists, nor the mental creation of a universal ex nihilo, as envisioned by some nominalists. It is also does not have any necessary dependency on induction.

What counts as accidental may vary with the context of evaluation. While distinctions of essence and accident are fairly stable within a given context, they are ultimately relative and contextual. The pertinent context includes not only contingent facts about what is being evaluated, but also the purpose of the evaluation.

In other, non-Aristotelian contexts, Badiou has recently made it somewhat fashionable to speak literally about “subtraction” instead of “abstraction”. Though I have many issues with his thought, this is actually a useful clarification.

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.)
