“The Subject” in Medieval Times

According to Alain de Libera in the second half of Archéologie du sujet vol. 1, Thomas Aquinas was instrumental in developing a view of the soul that was neither Aristotelian nor Augustinian, and that paved the way for the modern concept of “the subject” as an agent, long before Descartes. De Libera says that Aquinas did this in part by introducing the different, very abstract Aristotelian notion of subject (hypokeimenon, “thing underlying”, with no connotations of mind or agency) into the Augustinian model of the soul as an image of the Christian Trinity, and simultaneously introducing the Augustinian biblical Word into an Aristotelian model of abstractive knowledge. Aquinas also drew indirectly on Plotinus, and directly on his teacher Albert the Great’s use of pseudo-Dionysius. In doing so, he effectively removed the stigma Augustine had placed on treating the human soul as a “subject”.

Aristotle had suggested that there is a kind of identity between thinking and what it thinks. It is perhaps not accidental that we use different senses of the same English word “thought” for both. These should not be equated with subject and object in the modern sense; they both occupy parts of a kind of middle ground between what we call subject and object.

According to de Libera, Plotinus developed a kind of identity between three terms (nous, noeisis, noeton — intellect, intellection, intelligible object). His intellect and intelligible object are already somewhat closer to what we call subject and object. In between, he placed an act of thinking or intellection that was to have a kind of identity with both the intellect and the intelligible object.

Plotinus’ notion of act is also quite different from that of Aristotle. Aristotle calls the first principle a kind of pure act that is not an action in the ordinary sense, and has nothing else behind it; for Plotinus, the first principle is a power, and every act is the act of a power. For Aristotle, the first principle is also an end only; for Plotinus, it is both the end and the origin of all things.

The persons of the Trinity are supposed to have a sort of mutual immanence to one another that is completely unlike the case of something underlying something else. De Libera notes that Plotinus and his student Porphyry already used a similar concept of mutual immanence in their discussions of intellect. Augustine ranked his reading of Plotinus as a formative experience second only to his conversion to Christianity.

From the Christian neoplatonist pseudo-Dionysius, Albert the Great drew the notion of a “whole of powers” that is different from either a universal whole or an integral whole.

De Libera notes that the classic formula of the Trinity in Greek — one ousia, three hypostases — was confusingly translated into Latin as “one essence, three substances” or as “one substance, three persons”. By substitution, the coexistence of these two translations yields the obviously self-contradictory formula, “one substance, three substances”, which graphically illustrates the equivocation in medieval usages of “substance”.

(In deference to common usage, I have continued to use “substance” for Aristotle’s ousia, even though I think it is a terrible translation. “Essence” is better, provided we recognize that Plato and Aristotle had views of essence that were not “essentialist” in the sense of treating essences of things as pre-given or as something to take for granted.)

De Libera speaks of the need to parenthesize modern notions of subject and object in order to understand Augustine’s opposition to treating actions and passions of the soul as attributes of a substance. Conversely, for better or worse, Aquinas’ legitimation of this way of viewing the soul brings us closer to modern views. (I think Aristotle would have shared Augustine’s opposition to this formulation, but for different reasons. I think Aristotle regarded the whole human being — and not the soul or the body taken separately — as a “substance”.)

Aquinas introduced emphasis on both what de Libera calls an Aristotelian structure of subject-powers-activities and a pseudo-Dionysian structure of essence-power-operation into a Latin-speaking theological context that had been mainly dominated by Augustine. What I would call this double infusion of additional neoplatonic elements is said by some to have resulted in a more dynamic and relational way of viewing things. (In agreement with Gwenaëlle Aubry, however, I think Aristotelian potentiality is very different from neoplatonic power, even though they use the same Greek word.) Combined with Aquinas’ serious embrace of a version of Aristotelian hylomorphism, this infusion led to a simultaneously more positive and more dynamic view of worldly existence than had been common in the Augustinian tradition, which also helped lay the seeds of modernity.

A broadly neoplatonic view of the world in terms of powers and operations-of-powers thus turns out to have been very important for the emergence of the modern subject-as-agent (as well as, I would argue, the rise of the specific modern notion of causality). De Libera notes that Heidegger ignored both neoplatonism and theology in his famous account of the rise of the modern subject. Meanwhile, Aquinas’ legitimation of the treatment of actions and passions as attributes of a soul-subject-substance — coupled with the interweaving of such attribution with imputations of responsibility — seems to have contributed to a stronger notion of a self as something with univocal identity and sharp edges.

Origins of a Subject-Agent

How did the modern equation of subjecthood and agency come to be? How did the notion of “I” or ego come to be substantialized? An extremely influential argument of Heidegger makes this an innovation of Descartes. Alain de Libera argues that this is too hasty, and that the groundwork for this identification was actually laid in the later middle ages. I’m continuing a high-level treatment of de Libera’s extremely important “archaeology of the subject“ (see also On a Philosophical Grammar).

Answering this question will involve an extended historical odyssey through complex interactions between Aristotelian and Augustinian views, and much more. De Libera sees Aquinas in his polemic against Averroes raising four interrelated questions of a more fundamental nature: Who thinks? What is the subject of thought? Who are we? What is man? The second of these seems to have been first asked by Averroes. The other three are largely attributable to Aquinas and his contemporaries, in their reactions to Averroes.

Several points of Aristotelian interpretation (What is substance? What is form? What is act? What is an efficient cause? What is the soul?) will be relevant to answering these, as will Augustine’s meditations on personhood and the nature of the Trinity. De Libera notes that John Locke — a major contributor to modern views on “the subject” — was deeply involved in debates on trinitarian theology. He also discusses Franz Brentano’s modern revival of the medieval notion of intentionality. The medieval version was closely bound up with a notion of “inexistence” or “existing in” of mental objects (forms separated from their matter) in the soul.

In the Categories, Aristotle gives substance the logical sense of something standing under something else. This influenced the Greek grammarians who formulated the notion of a grammatical subject. But in the Metaphysics, he treats this as only a starting point that is quickly superseded by an identification of substance with form or “what it was to have been” a thing, before moving into an account of substance as potentiality and actuality.

De Libera notes a historic division among readers of Aristotle’s treatise On the Soul between those who interpret the soul as an attribute of the body, and those who treat it as a substance in its own right. The latter position has different meanings, depending on whether substance is taken in the “standing under” sense or in the sense of form. De Libera will be particularly interested in the consequences of a further family of positions that make the non-obvious equation of human actions and passions with attributes of the soul.

He notes that “category” in Greek originally meant accusation, and relates this to Locke’s characterization of personhood as a “forensic” notion. We have here to do with subtle relations between attribution, inherence, and imputation with respect to actions and passions in relation to the soul. But what is an action? Must we explain an act in terms of a substantial subject’s power of efficient causation in a late scholastic sense that is far from Aristotle’s? (See also Expansive Agency; Brandomian Forgiveness.)

On a Philosophical Grammar

It seems like a good time to get back to a bit more detail on Alain de Libera’s “archaeology of the subject”, which I introduced a while back. Volume 1 is subtitled Naissance du sujet or “Birth of the Subject”. He begins with a series of questions asked by Vincent Descombes in a review of Paul Ricoeur’s Oneself as Another:

“1) What remarkable differences are there, from the point of view of use, between these words which we place too lazily in a single category of personal pronouns (and particularly here I, he, me, him, her, oneself)?

“2) What is the status of intentions to act? Are they first properties of the agent?

“3) Should we distinguish, as Ricoeur proposes, two concepts of identity, identity as sameness (idem) and identity as ipseity [“selfness”] (ipse)?

“4) What is this self that figures in the expression self-awareness?” (Archéologie du sujet vol. 1, p. 31).

The birth of the subject in the modern sense is what de Libera will investigate. He aims to show how “the Aristotelian ‘subject’ [hypokeimenon, or thing standing under] became the subject-agent of the moderns in becoming a kind of substrate for acts and operations” (p. 39). He quotes a famous passage from Nietzsche denouncing the “grammatical superstition” of the logicians who assume that wherever there is a predicate for an activity such as thinking, there must be something corresponding to a grammatical subject that performs it. Nietzsche says that a thought comes when it wants, not when I want.

De Libera asks, “How did the thinking subject, or if one prefers, man as subject and agent of thought, first enter into philosophy? And why?” (pp. 45-46). He points out the simple fact that a grammatical subject need not be an agent, as when we say “the boy’s timidity made him afraid”. He quotes Frédéric Nef to the effect that action is not a grammatical category. How then did “the subject” become bound up with agency?

He notes that something like this is already at play in Aquinas’ Disputed Questions on the Soul, when Aquinas develops the notion of a “subject of operation” related to sensibility, associating the subject of an action or passion with a power of the soul. How, de Libera asks, did we come to assume that every action requires “an agent that is a subject” and “a subject that is its agent” (p. 58)? (See also Not Power and Action.)

He will be looking for medieval roots of notions that most people, following Heidegger, consider to be innovations of Descartes. Meanwhile, de Libera recalls that Augustine had gone so far as to label it blasphemy to call the soul a “subject”. Knowledge and love, Augustine said, are not in the mind as in a subject.

Aristotelian Subjectivity Revisited

My previous article on this was a bit narrow, focused only on an Aristotelian analogue for the sort of “transcendental” subjectivity developed by Kant and Hegel. Of course, the whole field of “subjectivity” is much broader than that, and properly transcendental subjectivity has little to do with the empirical subjectivity that we have in mind when we call something “subjective”. Here I’d like to begin to round out the picture. (In the background, I’m also imagining what Aristotle might say in response to Hegel’s Phenomenology.)

It is in fact something of a truism that none of the Greeks had a modern concept of the human “subject”. The closest (still distant) analogue is what gets conventionally translated by the etymologically related term “substance” in Aristotle. The elementary notion of substance as a literally existing logical/syntactic substrate for properties –“something underlying something else” — from the Categories was influentially referred to by Heidegger as “subjectity” (intended to stand in constrast to “subjectivity“).

The explanatory role of a literal notion of substrate is raised again in the Metaphysics. Aristotle says the most obvious candidate for a substrate of things is matter. But then he goes on to deconstruct and ultimately discard the whole notion that the most important kind of explanation of things involves reference to a literal substrate. Form — identified with essence or definition, and “what it was to have been” a thing — is then developed as providing more fundamental explanation than any substrate; then form itself is given a deeper explanation in terms of actuality and potentiality.

But neither the elementary account of “something underlying” in the Categories nor the sophisticated discussion in the Metaphysics makes any reference at all to the sentience and agency that are equally fundamental to modern notions of a human “subject”.

Separate from all of this, Aristotle identifies humans as those animals that have language and the ability to reason, which he considers as depending on language. I have argued that the main resource for an implicit notion of transcendental subjectivity in Aristotle is actually his ethical writings. The treatise on the “soul” (psyche) deals with bodily growth, nutrition, movement, and reproduction; with sense perception and imagination; and also with thought, which he refers to as coming to the soul “from outside”. Related treatises address memory and dreams. Human emotions, on the other hand, he deals with not in the “psychological” treatises but rather in the Rhetoric. The context in which Aristotle treats emotion is thus social and communicative rather than inward-looking. He also treats a kind of emotional maturity as a prerequisite for ethical development. He has a refined and well-differentiated notion of situated agency and ethical responsibility, but lacks the obsession with identity shown by many later authors.

I want to suggest that the “whatness” of subjectivity-forms — whether empirical or transcendental — is far more interesting and practically relevant than the supposed abstract “existence” of subject or substrate entities. This is true regardless of whether we are dealing with empirical or transcendental subjectivity. In Heideggerian terms, I want to decouple subjectivity from presumptions of subjectity.

As regards the Aristotelian soul, in Naissance du Sujet (volume 1 of Archeologie du Sujet), Alain de Libera lists four recent analytic interpretations: 1) the psyche is identical to the body; 2) the psyche is an attribute of the body; 3) the body “constitutes” the psyche; 4) the psyche is an immaterial substance. Actually, none of these seems to me to adequately capture Aristotle’s hylomorphism, or notion of the complementarity of “form” and “matter” (neither of which individually means quite what it might seem to, either — see above links). I am also sympathetic to the reading that Aristotelian matter is a relative concept, so that something could be the material for something else that is in turn material for another thing. Something similar, I think, could be said of form.

The relation of soul to body is clearly presented as an instance of the relation of form to matter, though it seems that the relation of form to matter may be different in different cases. In any case I do not think the form/matter relation is intended as an instance of the substance/accident relation. (The notion of “substantial form” was an original development of the Latin medieval tradition, not found in Aristotle, and the bits I understand of the medieval debate on unity or multiplicity of substantial forms further complicate the picture. The key to this whole territory is to understand that there are very many highly distinct and sophisticated positions in the tradition on issues of this sort.)

A further complication involves the relation between “soul” and the “intellect” that “comes from without”, which has a long and fascinating history in the commentary tradition, extending from Alexander of Aphrodisias through the Arabic tradition to the Latin tradition of Albert the Great.

The great Arabic commentator Averroes was apparently the first to ask what is the “subject”, in the substrate sense, of human thought. He came up with the novel suggestion that individual human thought has two such “subjects”: one belonging to the soul that is involved with the body and perception, and one that is an immaterial source of concepts, belongs to the whole human community, gains content over time, and would cease to exist if there were no more humans.

Another intriguing complication in the historical Western tradition is the clear stance taken by Augustine that human mind, soul, or spirit should definitely not be taken as a subject in the substrate sense, e.g., for knowledge or love.

Archaeology of the Subject

Leading scholar of medieval Latin thought Alain de Libera (b. 1948; automated translation of French Wiki page here) has produced a great deal of fascinating work. Well-versed in contemporary continental and analytic philosophy, de Libera excels in developing the sort of historiographical-philosophical nuances that I think are vital to solid understanding. He makes exemplary original use of Foucaultian archaeology and what I have been calling Aristotelian semantics, developing many fine historiographical distinctions in the use of philosophical words that turn out to have huge significance.

He has pointed out the large influence of Arabic philosophy on the Latin West (see Fortunes of Aristotle); contributed to a more balanced appreciation of the great Aristotelian commentator Averroes; documented the work of Albert the Great and his students, developing a surprising Aristotelian background to the German mystics; and explored the contemporary relevance of the medieval debate on universals.

His greatest contribution, however, is undoubtedly the ongoing work on an Archaeology of the Subject, with three volumes in French published so far, and related lectures at the Collège de France 2013-2019. I just stumbled on a related article in English.

The article introduces this work by noting a convergence between Foucault’s late “hermeneutics of the subject” and Paul Ricoeur’s book Oneself as Another, suggesting that late Foucault’s “subject” is actually close to Ricoeur’s positive notion of “self”. Ricoeur had said that this self stands “at an equal distance from the cogito exalted by Descartes and from the cogito that Nietzsche proclaimed forfeit” (emphasis in original). (In Freud and Philosophy (French ed. 1965), Ricoeur had referred to psychoanalysis as an “archaeology of the subject”.) Meanwhile, de Libera points out, the French philosopher Vincent Descombes, in defending a positive role for the notion of “subject”, concluded “the subject which it is necessary for us to discover is more Aristotelian than Cartesian”. While de Libera’s terminology is different from the way of speaking I have been developing here (see The Ambiguity of “Self”; Self, Subject; Subject; Empirical-Transcendental Doublet), there is a great deal of common ground, and I have been influenced by his work.

The main historical thesis advanced by de Libera is that the modern notion of “subject” is the result of a complex theological compromise and hybridization between initially very different notions of Aristotelian hypokeimenon (a generic notion of substrate with no intrinsic connection to personality, used by Averroes in raising apparently new questions about what substrate it is in which thought inheres) and Augustinian thought about hypostasis (the Greek term used for a person of the Trinity). I am barely scratching the surface of a highly developed account with many additional distinctions. (See also Pseudo-Dionysius on the Soul.)

This is a vital correction to many grossly oversimplified views of the history of notions of subjectivity in the Western world. My own view of the theological developments he highlights is a good deal more ambivalent, but compared to the value of this historiographical contribution, that seems like a minor difference.
