Turn to a Subject

This continues a reading of Jean-Baptiste Brenet’s Transferts du Sujet (2003). Up to now, broader themes related to the common modern assumption that there must be a univocal “Subject” behind all the varied appearances and experience of subjectivity have remained mostly in the background. Now they are beginning to move to center stage. How did we get to a point where it seems natural to attribute all our particular thoughts, feelings, and perceptions to a tight unity called “the Subject”?

Plato famously likens the soul’s unity to the rather loose one of a city. Meanwhile the Aristotelian word translated as “subject” (hupokeimenon) has no specifically psychological meaning. It is a much more general logical term that applies to anything that in a quasi-syntactic way “stands under” something else. Brenet uses the Heideggerian term “subjectity” to distinguish this older meaning.

Augustine insists on the active character of the soul, as an image of God and analogue of the Trinity. Contrary to Aristotle, he attributes an immediate reflexivity to the soul or mind. But he sharply rejects the idea that the soul or mind is a “subject” (subiectum). Augustine argues that this would make things like knowledge and love inhere in us as mere properties or predicates.

But in the 13th century, the Latin translation of Averroes’ Long Commentary on Aristotle on the soul raised the question what is the Aristotelian “subject” of thought? Augustine’s followers began to insist on exactly what Augustine rejected. This is the point at which the term “subject” acquired a psychological meaning. Brenet points out its adoption by the Augustinian William of Auvergne, whose work Brenet previously translated to French.

“[W]hen the reading of Averroes began, the notion of ‘subject’ was already on the scene. An exemplary witness is the work of William of Auvergne, bishop of Paris between 1228 and 1249. William asserts not only that the human soul is the ‘subject’ of thought, but that it knows itself reflexively as ‘subject’…. [I]t is the knowledge that it knows, and the knowledge that it knows as the subject of knowledge. This is not a deduction that from acts of knowledge oriented toward objects conjectures the existence of a power serving as their substrate, but indeed the knowledge of the self as that subject” (Brenet, Transferts du sujet, p. 333, emphasis added, my translation throughout).

According to Brenet, William takes up Avicenna’s metaphor of the flying man. “If since birth a man were suspended in the air, without use of any of the senses, he will nonetheless necessarily think, and think of himself as thinking, as a spiritual substance, as receptor and substrate of the intellectual forms. Besides the recurrence of the word subiectum, attributed to the soul in this spiritualist conception of the human, the great interest of William of Auvergne’s psychology lies in the combination he makes of this notion of ‘subject’ with the dynamic one of ‘agent principle’ (principium agens). The thinking soul in effect is not pure passivity…. It must be actrix and effectrix…. (this is why William, a firm adherent of the principle of the indivisibility of the soul, rejects the division within it of an agent intellect and a receiving intellect). The sensible is nothing but an occasion for an immanent act of intellection, which excites the soul to produce its own proper concepts from itself and within itself. William cites the joint authority of Augustine and Boethius here…. When it thinks itself, as a result the soul apprehends itself as the receptacle of a self-engendered knowledge; it is like the water of the sea or a river that welcomes the fish to which it gives birth” (p. 334).

“This is a captivating double aspect for us: first of all because, having been said of the human in a fundamental sense (the human is her soul, and it is first of all as subject….), the subiectum in William of Auvergne is intimately related to an idea that our modernity retains: an active power of foundation, a causal determination of acts…. Secondly, because William of Auvergne injects the concept of the subject into an Augustinian analysis of cognitive processes or of spiritual knowledge that a priori does not tolerate it. We know in effect that Augustine rejects the model of ‘subject’ as support of accidents, for thinking the relation that is maintained between the spirit and its faculties” (pp. 334-335).

Brenet summarizes the view of Augustine:

“The spirit knows that it understands and thinks, it knows itself entirely in its proper substance; and it is not as ‘subject’ that it is present to itself; it is that being of which the very essence is to know itself; it is not as attributes that its spiritual powers are manifested, since they each reveal to the spirit its own being or substance. Neither intelligence, nor memory, nor will, etc., is a quality in the spirit, inhering in it. The spirit is made in the image of God, who in the proper sense does not subsist (God is not susceptible to being the subject of accidents that affect their bearer). It is the model of the Trinity itself that allows the relation of the faculties and the spirit to be thought. That is to say, the circumincession of the Persons, or perichoresis (perichoresis being the mutual immanence of the Persons of the Trinity)” (pp. 335-336).

“It is thus necessary to think the relation of the powers to the spirit as like that which the divine Persons have to God. In the ‘perichoretic model’, to take up the expression of Alain de Libera, the spirit and its faculties, while being distinct from one another, are essentially one. The paradigm of inherence of qualities in the subject is indeed inoperative in this context, and its rejection leads to the expulsion of the Aristotelian notion of hupokeimenon [underlying thing] from the field of psychology” (p. 336).

“From this angle, William of Auvergne’s theory of the soul breaks the project that wants to be Augustinian at the heart. In elucidating the unity of the mens [Augustinian “mind”] with the subiectum, that is to say the infallible intuition that gives the soul knowledge of itself as ‘subject’, the Parisian bishop did much more than enrich a vocabulary. He crossed two models that the Middle Age up to that time had kept distinct: a theory of the me as clear presence to self, and a theory of the subiectum as being sub-jacent. He introduced subjectity in the soul, and conferred on the thinking human, active in this production, the new status of support of mental acts” (pp. 336-337).

“Having once raised the preceding considerations, we can better appreciate the anti-Averroist solutions of Durand de Saint-Pourcain and Herve Nedellec, who both affirm that the human thinks only as subject of the intellective act…. Before the problem posed to the Latins by the duo subiecta [two subjects] of Averroes, there was already question of the human-subject of thought” (p. 337).

“What effectively characterizes the anti-Averroist conception that John of Jandun confronted, and what is progressively put in place, is a new articulation of ‘human’ and ‘subject’…. It is not only a matter of saying, like William of Auvergne, that the soul is the subject of intellectual sciences, and that it thinks itself as such. It is not only a matter of posing, with Thomas Aquinas, that that by which the human thinks can only be her substantial form. It is necessary from now on to ensure, like Durand de Saint-Pourcain and Herve de Nedellec do, that the human can only be thought in her status as subject of the intellective act” (ibid).

“One says not only that the human thinks, and that she is the subject of her thought, but that she thinks insofar as she is the subject, on this condition alone. ‘Subject’ is not the term that one predicates of the thinking human (in supposing the necessity of a sub-jective power, assuring the possession of acts of knowledge), neither is it how she intuits herself, but rather it is the very thing on which the propriety of her acts in thought depends. Otherwise said, it is less the appearance of the subiectum in the field of psychology that we remark on here, than its place in the anti-Averroist project of the Latins. The notion of subject, applied to the human, becomes the centerpiece of the offensive. Where did this come from? What authority justifies that one has recourse to a ‘subject’ in the conceptual construction of these responses? None other than that, evidently paradoxical, of the Long Commentary itself. It is from the text of Averroes that the Latins take the idea that they oppose to him” (p. 338, emphasis in original; see “This Human Understands”; “This Human”, Again; Averroes as Read by de Libera).

“The faulty reading of the theory of ‘junction’ and of the duo subiecta brought about the appearance of two things: on the one hand the attribution to the human, by the inclination of her images, of the title of subiectum; on the other hand the idea that the individuality of thought depends on this status. This is to say, combining the two: that the human only comes to think under her subjective condition, insofar as she is subject, if not of thought, at least of the intelligible species that lead to it. It is this articulation that the Latins preserve, while denying that it can be realized in the system of Averroes. They denounce in him the impossibility of a thing whose importance was invented by their misunderstanding. It is in the work of the Cordovan, interpreted crookedly, that this adjunction was brought out that was supposed to rationally justify the multiplicity of acts of intellection, in spite of the unity of the intellect” (ibid).

“As a consequence, the pivotal role of this transposition of subjectity into the human is not attacked, any more than it is in Thomas Aquinas. When the Aquinate reproaches Averroes for making the human only a being that is thought, and not a thinking one, in truth he has no issue with it being said that the image is the ‘subject’ of the intelligibles, and indeed with the placement of the human so that she thinks as the subject of universal species: he does not contest the idea of the human-subject, but the fact that reason is given for a doctrine in which individual images, and ultimately the individual herself, are nothing but furniture for the act of intellect. Averroes claims that the thinking human is (also), by means of her images, subject of the intelligible, but this is theoretically impossible for him, since the image has to be abstracted and by it, in it, the human can receive nothing of the universal” (ibid, emphasis in original).

Brenet is not saying that images and the individual are mere furniture for Averroes, but recalling that according to Aquinas’ critique, they would be.

“In fact, Aquinas does not insist on the term subiectum — which after a few years became, notably among other Dominicans, a decisive philosophical element that was believed to take Averroes at the stronghold of his own logic, and show that it is incapable of satisfying its principal postulate: contrary to what [Averroes] says, the human is not the subject of the intellecta in actu, and the intellect in which the intelligibles are truly subjected has nothing to do with the human or the individual” (pp. 338-339).

“When we look at the 70 years that separate the entry of the Long Commentary into the Latin language from the intellectual activity of John of Jandun, we are as it were constrained to ask why the notion of ‘subject’ came to play a preponderant role in regulating the problem of the individuality of thought. Why is it all based on a certain arrangement of the triad human-subject-thought? How, in the paradoxical opposition to the noetics of Averroes, did the matter of intellectual individuation become in part constituted or effectuated in the University as the question of the subject? The idea of the human as subject of acts of thought was not the already available counter-argument, and the evolution of formulae from Thomas Aquinas to Durand de Saint-Pourcain or Herve Nedellec is revelatory of the intense elaboration that took place, up to the vindication of a human subjectity for thought” (p. 339).

“While Averroes posed the question of the noetic subject of thought, the Latins, based on his text, problematized that of its personal or human subject. This came down to transposing subjectity into the human, to placing into the terrain of subjectity, insofar as it is human, the problem of the humanity of thought, that of her individuation, that of thought’s appropriation by singular persons” (p. 340).

“This human who thinks, Socrates, is the body composed with intellect: an aggregate, a whole that unites the soul that cogitates and that which thinks. When thought is produced, intellect is not only a separate intelligence whose act passes on occasion by the intermediary of human images and is joined by humans who are humans without that; on the contrary, ‘it’ enters into the definition of each person. Even if in a non-substantial way, ‘it’ is constitutive of what individuals think. Otherwise said: in its separation, intellect is a part of the thinking human; and from this angle the humanity of the latter participates as ‘intrinsic operator’ that exists as her form” (p. 341).

“Thomas Aquinas says that a thing only acts by its form? John of Jandun too! Durand de Saint-Pourcin says that an individual can only think if the subject of thought is aliquid hominis [something human]? John of Jandun too! Certainly they don’t strictly understand the same thing: because this form and this subject are for John an ‘intrinsic operator’ without substantial support, because it raises an issue for personal immortality, etc.; no one denies the importance of these disagreements. Nonetheless, John shares this idea that it is necessary to include intellect in the human, and not only unite the latter to thought. We can see the effect of [Siger of Brabant’s] De anima intellectiva, but not only that; it is the effect of a previous Latin problematization that poses the subjection of the concept in the human as the condition of her proper thought. One could say also: which required that intellect in its entirety be an intellective soul. If we say that Averroes decentered the subject, John of Jandun recentered it: this thought is mine if that which it operates as thought is ‘of’ me” (ibid).

I have frequently commented on the non-Aristotelian character of the common scholastic term “intellective (or intellectual) soul”. Here we see its motivation.

“With Siger of Brabant, John constructs his response in two stages: he shows first that intellect-operans intrinsicum, along with the body, is a part of the thinking human; then, playing anew with the cosmologico-noetic analogy, that the act of a part can be referred back to its whole. On the basis of the human-aggregatum, the second function of the celestial comparison is in effect to indicate that the act of a part can be attributed to the composite — a way of maintaining with Aristotle that ‘it is the human, by her soul’ who thinks, and not only the soul” (p. 342).

“Vision is only in the eye, in the organ that receives the seen, and nonetheless we say that the human sees…. When the human thinks, the intellect is operans intrinsicum for her” (p. 344).

“In his questions on the Metaphysics, John defends the idea of an effective unity, a unity realized by the production of an effect” (p. 346).

“The exclusivity of human being follows from the affinity that the cogitative, the best of the sensory faculties, has with intellect” (p. 349). “The intellect does not abstract the brute image, the image of brutes, it requires a preliminary refinement…. The human intellective soul is the first of the separate forms, the most distant from the First, and the cogitative is the last and most spiritual of material forms” (p. 350).

“More exactly, without the existence of bodies the intellect cannot accomplish its end, which is the thought of the pure intelligibles, junction with the separate beings and with God” (p. 352). “Without the body, which conditions the engenderment of the intellect in habitu, the intellect, deprived of adeptio, cannot really be intellect…. Intellect depends on the human species, conceived as an uninterrupted succession of multiple supports of images, and not on this or that one in particular” (p. 353).

“The cogitative is a sensitive soul, the perishable form numbered with the humans, inherent to the body. It is its individual proper form, which also constitutes its specificity. Moreover, and without contradiction (on the contrary, because the order of the universe requires it), the human has a second substantial perfection, which is aggregated to her body in thought…. The human is not only a cogitating body, the bodily individual, but the whole formed by the operative unity of intellect with the body” (p. 357).

“For one who asserts that the possible intellect is unique, it remains to find solely in the particular organic faculties of humans the reason justifying the diversity of their thoughts” (pp. 358-359).

“A human thinks if she produces the act of thinking…. [T]he vocabulary of junction is succeeded by that of production, and the idea of a continuatio with the intelligible in act is succeeded by that of a production of the intellective act itself” (p. 361). “It is in the individual herself that thought is produced, and it is the internal dimension of its engenderment that makes a thought her own…. In estimating that junction with the intelligible in act is equivalent to production of the act of thought, that this production is the act of the human and that it occurs within her, John distances himself [from Averroes]” (p. 363). “John’s position coincides on an essential point with the anti-Averroist theses of certain great doctors of the School…. In spite of all their oppositions, John supposes no different thing: the human produces thought, and it occurs in her” (p. 364). “More generally, the act of intellect is attributed ‘denominatively’ to the human, in the measure that the last is in some way the cause” (p. 366).

“What governs the question of individual thought is not a doctrine of continuatio like that of Averroes: it is the idea of an intellectual production founded on a theory of the ‘subject’: a theory of the human as subject of the actus intelligendi, such as is elaborated at nearly the same time, in thinkers like Durand de Saint-Pourcin or Herve Nedellec” (p. 368).

“Intellect” and the Body

The Latin scholastics invented strongly univocal concepts of “substantial form” and “intellectual soul”, and read them back into Aristotle. The work of Jean-Baptiste Brenet shows how this is interwoven with the prehistory of the modern notion of a psychological subject as a knower and agent.

In the book that served as his doctoral thesis, Brenet develops a case study of the “prince of the Averroists” John of Jandun, who turns out to be closer to his Latin peers than to Ibn Rushd (Averroes) himself. Brenet has also published French translations of Aquinas’ questions on soul and body from Summa Theologica, as well as a work On the Intellectual Soul by the English Averroist theologian Thomas Wilton, whose theses we will see are disputed by John of Jandun.

Averroes had insisted that it is only equivocally that intellect is said to belong to the same soul that is said to be the form of the body. According to Brenet, John of Jandun wants to avoid two extremes. The first, which he associates with Alexander of Aphrodisias, in effect makes the human intellect entirely material, by insisting on the univocity of Aristotle’s definition of the soul. The second, represented by Themistius, treats intellect entirely as a transcendent principle, and absolutely denies that it is the form of the body. This latter view is often mistakenly attributed to Averroes. But in any case, John of Jandun reverses this emphasis, and pushes for a more “Alexandrian” solution. He searches the text of Averroes in order to highlight all the passages where Averroes says or suggests that intellect, in spite of its transcendent dimension, is nonetheless also in some meaningful way ours.

“Against the noetics of Averroes, to which he opposes in the first instance the experience of personal thought, Thomas Aquinas maintains in his De unitate intellectus that intellect is ‘a power of the soul that is the form of the body’. He even comes to write in this polemical context that ‘intellect is the form of the body’. It is this ‘information’ that, according to him, confers to each of us a principle for thinking that is our own” (Brenet, Transferts du Sujet, p. 35, my translation throughout).

Siger of Brabant had argued against Aquinas that the relation between intellect and the body is not one of substance, but rather is a kind of operational unity. Intellect is not the substantial form of the body, but is properly called a sort of “intrinsic mover or operator” within the soul. John of Jandun “is a child of this inaugural dispute. He inherits words and formulas from it, but not only that: he subscribes to the scholastic idea and its expression, that it is the form of the body that gives thought to the human” (ibid, emphasis in original).

“In fact Averroes, who paid extremely close attention to the exact problem of the being of intellect in potentiality, did not really seek to know in what sense intellect, without qualification, could be the form of the body. On the one hand, it is in effect the perfection of the human [i.e., the composite of soul and body] that interests him; on the other hand, he nearly always proposes a divided approach to the question” (p. 46).

“Not only must we not speak vaguely of the relation of intellect to human individuals, but things do not go the same way with each ‘intellect’. What is involved may be the thought of an infant, or that of a sleeping person” (p. 47). “The essential of [Averroes’] Long Commentary is developed in the third book, in the arborescence of modes of possible junction for the human, when Averroes details the diverse degrees of mediation that lead to the immediate information of the intellect, acquired at the end of the theoretical stage of thought: at this moment, the agent intellect has become directly our form” (ibid, emphasis in original).

(Here we have explicitly an immediacy that is not originary, but rather is a product of mediation. Hegel was not the first to raise such a possibility.)

John follows Siger of Brabant in modeling human intellect on the celestial intelligences that were believed to move the spheres by which the motions of the stars were explained. Like Siger, he uses Averroes’ commentary on Aristotle’s On the Heavens to derive conclusions about human intellect that conflict with what Averroes says in his more famous Long Commentary on Aristotle’s On the Soul.

“If intellect is the form of the body, it is so insofar as it is an ‘operator’. Every form is a giver either of being or of operation: the intellectual soul is precisely forma dans operationem” (p. 72).

Not without some irony, Brenet observes that “If we abstract away the corruptibility of the individual body, as well as its composition, if we neglect the fact that intellect has need of the image and needs it in its primary operation, we can justifiably say that it is a ‘form’ analogous to the celestial intelligence that is the mover of a sphere ” (p. 84).

“Between an immaterial form and a body that are ontologically separate, there can exist a relation in the order of act, a purely functional relation…. Even if it is separate from its Intelligence in its being, [the celestial sphere] is united to it in a certain way, i.e., to recall what John says himself, ‘at least as subject‘…. subjectum or ‘place’: the sphere-subject gives place to movement, the act of the Intelligence has a place in this sub-jection ” (p. 85, emphasis in original).

“Certainly, the Parisian master could say, the anti-Avicennan and anti-Platonic empirical orientation of the noetics of Averroes means that the implication of the body in the elaboration of thought must be strong, but intellect only has need of the human body for making thought, and not for being there” (p. 86).

“If the celestial sphere is indispensable as subject-receiver of the act caused by the Intelligence, insofar as it receives movement, how can it be compared to the human body, which does not receive thought from the intellect and is not, in this sense at least, the ‘subject’?” (p. 87).

Note well that intellect is not said to be “received” by the human here. In this Averroes differs from Alfarabi and Avicenna.

“We do indeed find a cosmologico-noetic analogy in Averroes, but Averroes does not reason in the same way. He does not found noetics on cosmology, he does the inverse, and goes from analyses of the human intellect to say something about the celestial Intelligences” (pp. 87-88). “John of Jandun seems to reverse this relation when he layers noetics over cosmology” (p. 88).

For Averroes, this raises the “problem of Theophrastus [Aristotle’s collaborator and immediate successor]”: How can we say that the material intellect has no form of its own, and yet that it is a being?

“Nothing can be in act that we call a ‘this’, which is to say a body or a faculty existing in a body, like the sensory faculty. The absolute denuding of its being is the condition of its receptivity to universals; in order for it to potentially be the intelligible, there can be nothing of its own in its being-in-potentiality” (pp. 89-90).

Here he is effectively saying that no concrete particular can be “in act” in the Aristotelian sense. Being a particular involves accident, and accident is incompatible with pure act.

“If the material intellect is by definition ‘that which is in potentiality all the ‘intentions’ of universal material forms, and is not any being in act before having conceived it, it is excluded that its nature could be that of (prime) matter, that of the separate forms, or that of a hylomorphic composite” (p.91).

(I am inclined to think that the notion of prime matter (i.e., matter abstracted from the form with which it is ordinarily said to be inseparable, and supposedly having no properties of its own) is an interpolation due to Alexander of Aphrodisias.)

“As a consequence, the subject of the intelligibles… constitutes a being sui generis…. The interpretation that Averroes gives in the Long Commentary rests on a double rejection of the readings of Alexander of Aphrodisias and of Themistius” (p. 92).

Brenet quotes Averroes, “Alexander explains the demonstration of Aristotle concluding that the material intellect is not passive, that it is not something of which one says ‘this’, (aliquid hoc), that is to say a body or a faculty [existing] in the body, as intending the preparation itself [for the reception of intelligibles] and not the subject of the preparation. That is why he writes in his book On the Soul that the material intellect more resembles the preparation that is in the tablet that has not been written upon, than the prepared tablet itself” (pp. 92-93, brackets in original). Averroes continues, “But it is impossible to show the nature of the preparation proper to the intellect without having recourse to the nature of the subject, since the preparation proper to each subject is parallel to (currit cursu) the perfection and the form of the subject” (p. 93).

Brenet continues, “Otherwise said, Aristotle could not speak of the receptive power of the material intellect without considering the very essence of that intellect…. Averroes in effect rejects the idea that a form adjoining a corporeal substrate can be other than inhering in and mixed with it: an intellect-disposition of the body can only be a corporeal form whose implication in matter renders impossible any apprehension of the universal” (ibid).

Logical and epistemic access to universals is for Averroes neither natural nor supernatural. I like to call it “ethical”.

“As a consequence, contrary to what Alexander of Aphrodisias maintains, the material intellect is really or substantially the subject of the intelligible; it is not the accident of a support; it cannot be reduced to a pure disposition attached to the material composite” (p. 94). “Themistius errs too, because he makes the material intellect a substance in which is found the disposition to receive the intelligibles” (ibid).

“Averroes bases his conceptual elaboration upon the being of the material intellect, and it is this that governs his cosmologico-noetic analogy, i.e., a reflection on the subjectity of the subject of universals. His question is not: Is the receptive intellect a subject or not? but rather, What subject or what being must it be?” (pp. 95-96).

“Averroes and John of Jandun do not defend the same thesis. John holds that the intellectual soul is to the body of the human as the mover-intelligence is to the heaven it moves, whereas Averroes maintains that the ‘celestial body’, i.e., its ‘soul’, is to its intelligence and to the separate forms of the universe, that which the material intellect is to the agent intellect and to the intelligibles it receives. This does not mean that John’s idea, which remained very current throughout the Middle Age, is absurd, impossible, or absolutely contrary to what Averroes wanted to say” (p. 104).

“In not working on the problem of the ‘fourth kind of being’, John truncates cosmology and unbalances its relation to noetics…. The master of arts develops his reading of Aristotle and Averroes from the angle of a question that the Cordovan does not pose: what is it that unites intellect to the human body? Like Siger when he was cornered by Aquinas, he is already dominated by the will to find the kind of union that will allow us to say that hic homo intelligit [“this human understands”], or that homo formaliter intelligit [the human formally understands]” (p. 109).

“[Averroes] does not ask himself about the act that unites intellect and the human, but first of all about the very possibility of any intellectual act, about its material possibility. Under what conditions is the intelligible received? Where can it be received? These are his questions. He wants to determine what is the subject of thought, independent of seeking to know who thinks, which far surpasses the question of human consciousness and that of individual intellection” (ibid).

In a footnote, Brenet quotes Jean Jolivet: “The contingency of individual knowledge, the empiricity of its constitution, are overlooked by a globalizing conception of being, of thought, and of their adequation. Transposing the matter into modern terms (with the required precautions), one could say that Ibn Rushd elaborated a philosophy not of consciousness but of the concept, that puts itself on the same side as Aristotle, properly understood, but also that of Spinoza, Hegel, Marx” (p. 109n).

The “Averroist” theologian Thomas Wilton “judges that the agent intellect is neither a forma inhaerens nor a forma informans, but that it intervenes solely as forma assistens” (p. 116).

But “For the Parisian master, … our intellect is constituted by the possible intellect and by the agent intellect, and the latter is united secundum esse [in being] to the first. Clearly opposed to Thomas Wilton, the master of arts goes so far as to say [the agent intellect] is our form informans” (p. 117). “This comes back to his conception of the intellectus possibilis and of the intellectual soul: John in effect rejects the idea that the possible intellect should be in act, … just as he denies the fact that the agent intellect is not part of the human soul” (p. 118).

Therapy of Desire

Is philosophy a kind of therapy? Martha Nussbaum’s excellent The Therapy of Desire: Theory and Practice in Hellenistic Ethics (1994) impressed me greatly when it first came out. Looking at it again 30 years later, this ethical “therapy” turns out to follow a different paradigm from the emphasis on mutuality in dialogue that I have been addressing from various angles recently. The discussion has many interesting twists and turns.

What is philosophy for, anyway?

Nussbaum says “The idea of a practical and compassionate philosophy — a philosophy that exists for the sake of human beings, in order to address their deepest needs, confront their most urgent perplexities, and bring them from misery to some greater measure of flourishing — this idea makes the study of Hellenistic ethics riveting for a philosopher who wonders what philosophy has to do with the world” (p. 3).

Her main point in this early work is to exhibit the sophistication of Epicurean, Stoic, and Skeptical understandings of emotion. She highlights their practical commitment and “combination of logic with compassion” (p. 9). An important part of her argument, though, is that these later figures further developed themes that Aristotle already raised. I’m currently expecting to cover her first three chapters, where Aristotle plays a larger role. This post focuses on the introduction and first chapter.

“In order to get a purchase on this complex issue, I shall begin this book with Aristotle. For Aristotle sketched an account of the emotions and desires that is very close to the more elaborate accounts we find in the Hellenistic philosophers. And yet he did not defend a norm of detachment from the mutable good things of this world. His best human life is a life rich in attachments to people and things outside the self — friendships, family loves, political ties, ties of certain sorts to possessions and property. Thus it is a life rich in possibilities for emotions such as love, grief, fear, and even anger; the study of these connections will shed light, by contrast, on the Hellenistic conceptions” (pp. 41-42).

Aristotle’s positive valuation of various forms of emotion stands in opposition to these later philosophers.

The Hellenistic period is usually said to extend from Alexander the Great up to Roman times. Increased long-distance trade brought many cultures into closer contact with one another. Religions became detached from local traditional communities, with many coexisting side by side. The new philosophies that emerged in these times were simpler than those of Plato and Aristotle and more dogmatically presented, but still quite sophisticated and interesting. It is largely through them that philosophy for a while gained an unprecedented place in mainstream culture. Meanwhile, Aristotle’s uncirculated manuscripts were left to decay in the attic of a relative who had greedily claimed them. The great rise in Aristotle’s influence began only later, after a third or so of his uncirculated works were recovered and edited. (See Fortunes of Aristotle.)

“The major Hellenistic schools are all highly critical of society as they find it; and all are concerned to bring the necessary conditions of the good human life to those whom society has caused to suffer. They are, moreover, far more inclusive and less elitist in their practice of philosophy than was Aristotle, far more concerned to show that their strategies can offer something to each and every human being, regardless of class or status or gender. On the other hand, the way they do this has little to do, on the whole, with political, institutional, or material change. Instead of arranging to bring the good things of this world to each and every human being, they focus on changes of belief and desire that make their pupil less dependent on the good things of this world. They do not so much show ways of removing injustice as teach the pupil to be indifferent to the injustice she suffers” (p. 10).

I hold that a consistent application of Socratic-Platonic-Aristotelian philosophical values rules out any kind of elitism, by grounding everyday values in mutuality and reason.

“Aristotelianism sets exacting worldly conditions for the good life, making virtuous activity dependent in many ways upon material and educational conditions that are beyond the individual’s control. But Aristotle then assigns to politics the task of bringing those conditions to people: the good political arrangement is the one ‘in accordance with which each and every one might do well and lead a flourishing life'” (ibid).

Several important points about Aristotle are expressed in condensed terms here. Virtuous activity depends in part on conditions the individual does not control. Good politics should benefit all, not only some. He favors engagement rather than withdrawal, and he favors refining our emotional sensitivities rather than casting them aside or suppressing them.

On the other hand, “Epicurus urged a complete withdrawal from the life of the city, Skeptics an uncritical obedience to forces of existing convention. Even among the Stoics, whose commitment to the intrinsic value of justice is plain, we hear less about how to alter the political fact of slavery than about how to be truly free within, even though one may be (politically) a slave; less about strategies for the removal of hunger and thirst than about the unimportance of these bodily goods in a wise life; less about how to modify existing class structures and the economic relations that (as Aristotle argued) explain them, than about the wise person’s indifference to such worldly distinctions. In all three schools, the truly good and virtuous person is held to be radically independent of material and economic factors: achieving one’s full humanity requires only inner change…. I shall conclude that this criticism has some merit” (p. 11).

But there is also substantial common ground.

“[B]oth Aristotle and the Hellenistic thinkers insist that human flourishing cannot be achieved unless desire and thought, as they are usually constructed within society, are considerably transformed. (Both hold, for example, that most people learn to value money and status far too highly, and that this corrupts both personal and social relations.)” (ibid).

Here we come to the center of her reading, which is that for the Hellenistic philosophers, philosophy is a kind of therapy of the soul. (I note in passing the unanimity with which the philosophers denounce the overvaluation of money and status.)

“Epicurus wrote, ‘Empty is that philosopher’s argument by which no human suffering is therapeutically treated. For just as there is no use in a medical art that does not cast out the sicknesses of bodies, so too there is no use in philosophy, unless it casts out the suffering of the soul.’ The ancient Skeptical teacher, too, portrays himself as a healer of the soul. Being a lover of humanity, the Skeptic wishes to heal by argument, insofar as possible, the arrogant empty beliefs and the rashness of dogmatic people” (p. 13).

“Or as Cicero, speaking on behalf of the Stoa, more succinctly puts it: ‘There is, I assure you, a medical art for the soul. It is philosophy, whose aid need not be sought, as in bodily diseases, from outside ourselves. We must endeavor with all our resources and all our strength to become capable of doctoring ourselves’. Philosophy heals human diseases, diseases produced by false beliefs” (p. 14).

“All three schools, in short, could accept the Epicurean definition of philosophy: ‘Philosophy is an activity that secures the flourishing [eudaimon] life by arguments and reasonings.’ And all can agree that a precise, logically rigorous argument that is not well suited to the needs of its hearers, an argument that is simply and entirely academic and unable to engage its audience in a practical way, is to that extent a defective philosophical argument” (p. 15).

She contrasts all this with Augustine, for whom “God has set up certain ethical standards; it is our job to do what God wants. But we may or may not be endowed with the capability of seeing, or wanting, what God wants. Truth and God’s grace are out there; but the ability to see ethical truth or to reach for grace is not something we can control. There is, therefore, no reliable method by which we can construct an ethical norm from the scrutiny of our deepest needs and
responses and desires” (p. 18).

“For both Platonists and these Christians, digging more deeply into ourselves is not the right way to proceed in ethical inquiry” (p. 19).

Here we reach a matter of deep ambivalence, and correspondingly great interest. Nussbaum will argue that on this particular point, Aristotle is closer to the “therapeutic” attitude of the Stoics, Epicureans, and Skeptics than to the heaven-centered, more objectivist views of ethics that she attributes to Plato and Augustine. I broadly agree.

Referring to mytho-poetic imagery in Plato’s Phaedrus, she says “We do not inquire into the human good by standing on the rim of heaven; and if we did, we would not find the right thing. Human ways of life, and the hopes, pleasures, and pains that are a part of these, cannot be left out of the inquiry without making it pointless and incoherent. We do not in fact look ‘out there’ for ethical truth; it is in and of our human lives. More than this, it is something to and for human lives” (pp. 20-21).

For Aristotle, the Good is always concrete and situationally attuned.

“The medical conception of ethical inquiry opposes itself, as well, to another conception of ethics that stands, so to speak, at the opposite end of the spectrum from Platonism. This is the idea that ethical inquiry and teaching are simply the recording of traditional social belief and have no legitimate goal beyond this” (p. 24).

As Nussbaum points out, none of the Greek philosophers defends this kind of traditionalist view of ethics. The Hellenistic philosophers in particular see much that is wrong with the social world.

“For according to the Hellenistic philosophers, society is not in order as it is; and, as the source of most of their pupils’ beliefs and even of their emotional repertory, it has infected them with its sicknesses. The upbringing of young people is held to be deformed in various ways by false views about what matters: by excessive emphasis, for example, on money, competition, and status” (p. 26).

This is quite a far cry from the divine right of kings, the invisble hand, and other providential underwriting of the status quo that was claimed in early modern times. The Hellenistic philosophers dwelt more extensively than their avid readers in the Enlightenment on what modern people might call alienation.

Nussbaum next turns to address the limits of the therapeutic paradigm.

“All this suggests that the medical kind of ethics may be inclined — like medicine itself, but even more so — to adopt an asymmetrical model of the relationship between teacher and pupil, doctor and patient” (p. 27).

As she points out, at the heart of the therapeutic paradigm is an asymmetrical social relation. This stands in implicit conflict with the ideal of mutual and reciprocal relations in Aristotle’s ethics.

“Hellenistic ethics combines immersion with critical distance in something like this way — insisting on the rigorous scrutiny of belief and desire, while insisting, too, that it is to real people and their beliefs and desires that ethics must ultimately be responsible” (p. 28).

“In the course of developing their medical norms of health, the Hellenistic philosophers appeal to ‘nature’ and the ‘natural’. These slippery notions had better be scrutinized, since misunderstanding them could cause serious misunderstanding of the entire medical approach” (p. 29).

“The ancient appeals to nature that we shall be considering do not … pretend to derive value-norms from a value-free account of the ‘scientific’ underpinnings of human life. Ancient accounts of ‘nature’, especially of ‘human nature’, are value-laden accounts…. Norms follow from an account of ‘nature’ because the account is frankly normative to begin with” (p. 30).

The therapeutic paradigm’s appeals to nature ought therefore to be sharply distinguished from what 20th century philosophers called ethical naturalism. Even the account of nature is frankly normative from the outset.

“A good introduction to the Hellenistic appeals to nature, which clearly reveals both the normative and the anti-conventional thrust of these appeals, is in the famous lines of Walt Whitman’s Song of Myself concerning the animal kingdom” (p. 31).

“What the animals show Whitman is not a value-free realm of life; nor does he learn from them to glorify that which exists without effort or teaching. What he sees is that certain practices that (already) appear to him to impede human flourishing — practices connected with religious fear and guilt, with economic obsession and accumulation, with status and power — need not exist. Moreover, when they do not exist, certain deformations of life — sleepless fear, groveling subservience, anxiety, dissatisfaction — do not exist either. The ‘tokens of myself’ that the animals show Whitman are possibilities for self-respect, self-expression, and social equality that are frequently obscured by the realities of human social life. So too, I shall argue, in Hellenistic appeals to the nature of the child, the nature of the animal: the purpose is to construct a radical norm of true human flourishing. This norm is not value-free or ‘scientific’: it is justified by appeal to deep human desires and judgments, and it is value-laden; but it is highly critical of ordinary belief, and sees many of our ordinary beliefs as impediments to flourishing” (p. 32).

“The medical conception seeks to combine the critical power of Platonism with the worldly immersion of ordinary-belief philosophy. And it adds something further of its own: a commitment to action” (pp. 32-33).

“Philosophy understood along medical lines deals with both beliefs and emotions or passions. One reason why the tension described earlier seems to arise is that philosophy is asked not simply to deal with the patient’s invalid inferences and false premises, but to grapple, as well, with her irrational fears and anxieties, her excessive loves and crippling angers” (p. 37).

“Both Aristotle and the Hellenistic schools hold, furthermore, that many, if not all, of the passions rest upon beliefs that do not spring up naturally (if any beliefs do this), but are formed by society” (p. 38).

“All the schools dedicate themselves to the searching critique of prevailing cognitive authority, and to the amelioration of human life as a result” (p. 40).

But in contrast to Aristotle, “These philosophers do not simply analyze the emotions, they also urge, for the most part, their removal from human life” (p. 41). This idea of aiming to cast off all emotion I vehemently reject. Nussbaum too finds it troubling.

“Aristotle accepts and develops at length the idea that ethical philosophy should resemble medicine in its dedication to the practical goal of ameliorating human lives. And he develops, in some detail, aspects of the analogy between the philosopher’s and the doctor’s tasks. And yet Aristotle also criticizes the medical analogy at certain points, arguing that there are some very important ways in which ethical philosophy should not be like medicine” (p. 42).

She lists three points common to Aristotle and the Hellenistic philosophers.

“1. Arguments have a practical goal: they are directed at making the pupil better, and can be assessed for their contribution to this end. (This, as I said, does not entail that the value of argument must be merely instrumental.)
“2. They are what we might call value-relative: that is, at some level they respond to deep wishes or needs of the patient and, again, are to be assessed in accordance with their success in doing this.
“3. They are responsive to the particular case: just as a good doctor heals case by case, so good medical argument responds to the pupil’s concrete situation and needs” (p. 46).

Then she lists five more characteristics that apply to the Hellenistic philosophers but not to Aristotle.

“4. Medical arguments, like bodily medical treatments, are directed at the health of the individual as such, not at communities or at the individual as member of a community.
“5. In medical argument, the use of practical reason is instrumental. Just as the doctor’s technique is no intrinsic part of what the goal, health, is, so too the philosopher’s reasoning is no intrinsic part of what the good human life itself is.
“6. The standard virtues of argument — such as consistency, definitional clarity, avoidance of ambiguity — have, in medical argument, a purely instrumental value. As with the procedures of the medical art, they are no intrinsic part of the goal.
“7. In medical argument, as in medicine, there is a marked asymmetry of roles: doctor and patient, expert authority and obedient recipient of authority.
“8. In medical argument, the teacher discourages the sympathetic dialectical scrutiny of alternative views. Just as a doctor does not urge the patient to experiment with alternative medications, so the teacher does not encourage cognitive pluralism” (ibid).

Subject of Passion

Here I will very briefly treat Alain de Libera’s Le sujet de la passion (2021), which consists of his 2016 lectures at the College de France. The modern notion of a subject-agent, he has previously argued at length, has its origins not in Descartes but in Latin scholasticism. Here in part he takes the argument back further, to the Greek fathers of the Christian church and their speculations about the nature of Christ. He takes up the theme of a “decolonization” of the Middle Ages and of theology, which have been stigmatized since early modernity. As usual, he covers a vast territory that I will only sample.

He begins on a humorous note. “Sociopaths don’t yawn, we say. Or better, they do not know yawning by contagion. They do not suffer when they see someone else suffer. They do not know pity. Generally, they haven’t read Aristotle” (p. 12, my translation throughout). He recalls Aristotle’s numerous statements that action and passion reside in the patient, not the agent. 

He goes on to note how the 17th century writer Le Laboureur argued that French is superior to Latin, because its word order more explicitly refers every action to a subject. Le Laboureur claimed that “Cicero and all the Romans thought in French before they spoke in Latin” (p. 20). Bemusedly, de Libera points out that in the 20th century, Martin Heidegger claimed that French writers must do their thinking in German, because German is the naturally philosophical language.

“While the notion of subject-agent can appear as contradictory — it only has historical purchase once what I call the ‘chiasm of agency’, that is to say, the devolution of the functions and conditions of agency to the ‘subject’, has been realized –, the notion of subject-patient poses no problem: it is the sense that the word ‘subject’ originally had, otherwise said before the chiasm, the hypokeimenonsubjectum, which, we have seen many times, in Augustine as in Aristotle, designates a support or a substrate, … in short a bearer, a receptor of qualities or accidental properties.”

“This poses the problem of WHICH is the subject who suffers, then WHO is the subject who suffers, the passage from the WHICH to the WHO” (pp. 57-58).

Is there a single subject of thought, of perception, and of emotions? Or: Who says ‘I’ in ‘I think’, ‘I perceive’, ‘I feel’?” (p. 59).

“Can we say ‘it suffers in me’, like we say, with Schelling, it thinks in me?… We can perhaps admit that I am not the subject of my thoughts or that there is in me a subject of my thoughts that is not a part of me, but indeed only something in me, aliquid in anima rather than aliquid animae — for example, the nous, the intellect called ‘possible’ or ‘patient’ in medieval philosophy — but can this hold good for suffering, can it hold good for passion, can it hold good for what we today call emotion? We can doubt this…. Passion implies the body, suffering implies the body, we say. Thought does not imply it” (pp. 59-60).

“I respond: for a dualist [such as Descartes], thought does not imply the body. But not everyone is a dualist. For an Aristotelian, for example, especially an Averroist, intellect has need of the body, because it has need of a furnisher of images. It has need of the body and its images not as a subject, but as an object. Cannot the same argument be made for passion, for suffering, for pain?” (p. 60).

“[I]s it not evident that if there is a subject of my passion, it can only be a subject-patient, and that the last can only be me, whatever thing or entity the term ‘me’ designates: body, or soul, or soul united with a body…?” (ibid).

Emphasizing how christological debates among theologians have affected common views of the human, he recalls the aim of what he previously called a deconstruction of the Heideggerian deconstruction of subjectivity, which among other things ignores this aspect. 

“The articulation between Passion — upper case — and passion — lower case is the central element of the archaeology of the subject of passion” (p. 66).

“The central element is the introduction of hypostatic union into anthropology, otherwise said, the intervention of the subject — of the hypostasis — in the relation soul-body, and indeed in the relation spirit-soul-body… which makes possible the emergence of the person as subject where not only actions, but also passions are susceptible to imputation” (p. 493).

Form and Entelechy

In pondering the implications of Aubry’s narrower construal of form in Aristotle, an important case to consider is the classic definition of soul. The standard scholastic “soul is the form of the body” does in fact ultimately refer to Aristotle’s more precise statement in On the Soul book 2 chapter 1 that “soul is an entelechy of the first kind of a natural body having life as a potentiality” (Sachs tr., p. 82, modified). Entelechy is a strictly more powerful concept than form.

Plato calls the soul a form, but I always found it difficult to reconcile the soul’s apparent diverse activity in life with what Plato says about the eternal and apparently static nature of form.

On the other hand, Aristotle begins the chapter mentioned above by distinguishing form, matter, and the composite. And he says, “Therefore it is necessary that the soul has its thinghood [ousia] as the form of a natural body having life as a potency. But this sort of thinghood is a being-at-work-staying-itself [entelechy]; therefore the soul is the being-at-work-staying-itself of such a body” (p. 81, emphasis added).

Clearly, the quote I opened with is a more precise version of this, following Aristotle’s frequent pattern of first mentioning something in more colloquial terms, before offering a more definitive formulation of it.

The opening distinction of form, matter, and composite is even presented as a division of ousia. But Aristotle’s authoritative and in-depth discussion of ousia in book Zeta of the Metaphysics begins by distinguishing at least four senses of ousia, only one of which is an “underlying thing” (primary substance in the sense of the Categories). Then only “in a certain way” (ch. 3, Sachs tr., p. 119) are matter and form said to be of that sort. And the “underlying thing” sense is the one that is most left behind in Aristotle’s long development of what ousia really is.

The Self in Plotinus

Besides standing at a half-way point between Plato and Aristotle and later articulations of monotheistic theology, Plotinus occupies a special place in the history of subjectivity. In a 2016 document “Power, Subject, Sovereignty”, prepared for her confirmation as a director of research at the Centre National de la Rechereche Scientifique, Gwenaëlle Aubry treats her extensive work on Plotinus as the connecting theme of her philosophical investigations. I’m still waiting for the 2nd edition of her Aristotle book to arrive, and wanted in the meantime to extend my coverage of her work on subjectivity in Plotinus.

For the Routledge Handbook of Neoplatonism (2014), Aubry wrote an outstanding more introductory article that was translated to English as “Metaphysics of soul and self in Plotinus”.

“One of the great singularities of the philosophy of Plotinus consists in thinking of the self for its own sake and, in particular, in producing a concept of it different from that of soul. This philosophical breakthrough is inseparable from the discovery of immediate reflexivity, that is, the subject’s ability to apprehend itself independently of its relation to an object or to another subject. In Plotinus, however, this reflexivity occurs only in an interrogative form” (p. 310).

“In other words, it does not, as in Descartes, assume the form of an intuition by means of which the subject, grasping itself as consciousness, would, at the same time, have an evident revelation of its essence….[W]e will see how Plotinus, although he seems to think of the self by means of the connected notions of soul and human being, but also of individual or even of consciousness, ceaselessly produces and renews a gap between them and the self” (ibid).

Plotinus was the first to assert a kind of immediate reflexivity, and indeed arguably the first to speak of generalized consciousness in something like a modern sense, independent of particular contents. But this reflexivity remains associated with a sort of Socratic questioning, and does not degenerate into the dogmatic intuition of a present self that we find in Descartes.

“The self properly so called, which Plotinus refers to as the hēmeis (“we”), is distinct both from the essential or separated soul and from the soul linked to the body. Situated rather than defined, it cannot be substantified. To use Plotinian terminology, the hēmeis is neither god nor animal, but rather the power to become either one. These two possible and exclusive identifications depend on the orientation it gives to its consciousness. Consciousness therefore does not appear, as it will in Descartes, as a revelation of identity, but as a means of identification” (ibid).

“Another singular aspect of the philosophy of Plotinus is that it affirms the existence of a
separated soul, which remains in the Intellect and alien to both the powers and the passions of the body. This doctrine was to be rejected by the later Neoplatonists, particularly Iamblichus and Proclus…, but it occupies a fundamental place in Plotinian thought” (p. 311).

The “separated soul” is a unique doctrine of Plotinus that seems to have indirectly influenced the more unified scholastic notion of an “intellectual soul”. Later, Aubry refers to it as an “intellective soul”. By means of it Plotinus gives us an especially close connection to the divine.

“[I]f the Plotinian subject grasps itself only in an interrogative form, that is, not as something obvious but as something strange, it is because it undergoes the experience of several modes of relation to itself” (ibid).

“[S]trictly speaking, the intellective soul cannot be counted among the parts of the soul, and yet, it is indeed ours (hēmeteron); in fact, he continues, “it is ours without being ours … It is ours when we use it; it is not ours when we do not use it” (pp. 311-312).

Here Plotinus remains faithful to Aristotle in maintaining that intellect is not a proper part of the soul, and yet can still be said to be “ours”.

“Like the total Intellect, and each of the intellects of which it is composed, the higher soul is characterized by intuitive thought, that is, by the simultaneous, inarticulated and non-propositional grasp of a complex content – comparable to a glance that embraces all the features of a face in a single vision” (p. 312).

This is precisely the kind of originary intellectual intuition that Aristotle, Kant, and Hegel would deny. As Kant would say, this kind of unitary vision could only be a result of synthesis. But for Plotinus, unitary intellectual intuition is the starting point of all thought, which Aristotelian “thinking things through” only weakly imitates. Nonetheless, he retains a partial faithfulness to Aristotle in maintaining that this does not include a putatively full intuition of self.

“The soul’s forgetfulness of the Intellect is also a forgetting of its own intellective origin –
an origin that nevertheless has not come and gone, nor does it belong to a mythic past,
but that remains in a state of unperceived presence. This forgetfulness is characteristic of
pre-philosophical consciousness. Unaware of its dignity, soul is fascinated by externality:
the body, the sensible. Narcissistic, it prefers its reflection to itself, ignorant of the fact that
without it, this reflection, which is merely the effect of its power, could not subsist” (ibid).

For Plotinus, we remain potentially in touch with the separate intellective soul. All that is required to experience it is that we choose to turn ourselves toward it, but Plotinus says many people never make this choice, and instead remain ensnared in what Aubry calls narcissism.

“[T]his essential self constituted by the separated soul must indeed be distinguished from the hēmeis and from what we may call the biographical subject, that is, the bearer of a history, a memory, and the form of consciousness that is linked to them” (ibid).

“Like memory and individual history, consciousness disappears in the Intellect. More precisely, it gives way to a feeling of presence in which the duality between subject and object is abolished. In this state, Plotinus writes, we are ‘only potentially ourselves’ (Enn[eads].IV.4[28].2.5–8). We merge with that which we contemplate” (p. 313).

Here we really do have a “metaphysics of presence”.

“This state in which the subject no longer experiences itself as such, but in its unity
with being and with the others, is nevertheless designated by Plotinus as the site of its
greatest proximity to itself, at the same time as it is genuine self-knowledge: “Being in this
way, we are more than anything conscious of ourselves (hautois synetoi), and we acquire
knowledge of ourselves as we make ourselves one” (Enn. V.8.[31].11.31–3)” (ibid).

The subject experiences itself “in its unity with being and with the others”. Here we can see a precedent for the nonprivate interiority that distinguishes Augustine’s thought from that of Descartes and Locke. Clearly we have here a non-empirical notion of self.

“Still, the question arises of what the subject, thus identified with the intellective soul and unburdened of all biographical content, then grasps of itself. At this essential level, can we still speak of identity? Of individuality?” (ibid).

“The paradox of the Plotinian personal self is thus illuminated: if, for Plotinus, one is never
more oneself than when one is no longer conscious of oneself, this is because the subject identified with its essential soul is not abolished in the universal. Rather, it is identified with the very source of its individuality, that is, with the singular viewpoint of its intellect upon the total Intellect, as well as with the logos that bears the power of its own becoming” (ibid).

“Indeed, the notion of a separated soul orients Plotinian ethics, which has no other goal than to transform this constant but ordinarily unperceived presence into a conscious presence. Far from being immediate or mechanical, this transformation is given as a demanding, normed itinerary, whose various stages correspond to various degrees of virtue…. This ethical itinerary, and we shall return to this point, is inseparably a trajectory of consciousness, which gradually turns away from the body to orient itself towards the separated soul” (ibid).

Once again, here is a real “metaphysics of presence”.

“In truth, then, the Plotinian beyond is very close: to reach it, it is enough to make oneself deaf to the tumult of the body, to release oneself from narcissistic fascination. For Plotinus, Odysseus represents the anti-Narcissus: he is the one who was able to resist the spells of the sensible, the charms of Circe and of Calypso (Enn. I.6[1].8.18–20). Yet the Plotinian Odyssey is a return to something that is always-already-there, which is the locus in us of a divine autarky, lucidity and happiness” (p. 314).

Again, for Plotinus the divine is very near.

“[S]trictly speaking, for Plotinus the soul does not descend. What descends, or mixes with the body to animate it, is the power, the dynamis, that emanates from the separated soul” (ibid).

Here we have a profound difference from Aristotle. In Aristotle, soul is strictly emergent. Souls don’t pre-exist and there is no “descent” at all, only an upward movement.

“In its confrontation with the body and with temporality, noēsis [pure thought] is transformed into dianoia [thinking things through]. This is the moment by which the soul is truly constituted qua soul, in its difference from the Intellect” (ibid).

Plotinus has the unprecedented idea that soul is constituted as a “procession” from Intellect.

The pre-existent “separate” soul lives eternally in unitary intuition. For Plotinus, ordinary human “thinking things through” is the result of the extension, folding, and division of originary intuition into time. This “descent” is necessary in order for anything to be manifested, and therefore not to be equated with anything like Biblical original sin.

“The descent can be considered as a fall or a fault only when dianoia and the consciousness linked to it, forgetful of the separated soul, are completely oriented towards the body” (ibid).

For Plotinus, we are “fallen” beings not by virtue of our embodiment, but only insofar as we are individually lost in the soul’s narcissistic pursuit of its own reflection.

“As early as chapter 2 of Enn. IV.8[6], Plotinus states a principle: ‘It is not a bad thing for the soul to provide the body with the power of good and being, since it is not true that all providence applied to lower reality prevents this providential agent from remaining in what is best’ (2.24–5)” (ibid).

Soul in Plotinus is not just something that descends. It is the very agent of providence. But it is capable of being waylaid or losing its way.

“[T]he World Soul [as distinct from soul in general] does not “descend”. What is “sent” into the world is not it, but its “lowest power” (dynamis). Yet it is precisely because the World Soul does not descend that it is able to govern the universe, to set it in order into a cosmos, a beautiful totality. This point of doctrine is explicitly formulated elsewhere, for instance at Enn. IV.3[27].6.21: “The souls that incline toward the intelligible world have a greater power”; or else Enn. II.9[33].2, where one reads that the World Soul governs “simply by looking at what is before it, thanks to its wonderful power. The more it devotes itself to contemplation, the more it is beautiful and powerful” (15–16)” (p. 315).

Unlike Aristotle and the scholastics, Plotinus also speaks of a Soul of the World that is distinct from individual souls.

“This description of the mode of governance of the World Soul is nothing other than an application of the Plotinian model of causality. This states that from every being in act (energeiai) there necessarily emanates an active, productive power (dynamis), which in turn is the cause of a new being and a new act” (ibid).

This sheds light on how the descent of the soul is not inherently a fall. It is part of the larger cosmic process of procession (known via the Latin translations of Avicenna as “emanation”), which is what in Plotinus takes the place of creation. Plotinus seems to claim that when we turn toward the separated soul, from us too will proceed or emanate a productive power, capable anew of spontaneously carrying forward our engagement with the world in all its complexity. This spontaneous engagement, freed from narcissistic pursuit of our own reflection, is for Plotinus strictly more capable than a narcissistically involved engagement.

It is not worldly engagement as such but narcissistic attachment to worldly things that corresponds to the Fall.

“For the individual soul as for the World Soul, however, Plotinus emphasizes that it is this power, this dynamis, and not the soul itself, that descends and is mixed with the body. This is why the Aristotelian definition of the soul as first entelechy of the body must be opposed by the assertion that the soul is itself in act, already entelekheia, without the body, and that only for this reason there can be a body. Thus, the synamphoteron, that is, the living body, is not a mixture of body and soul, but only of the body and the power emanated from the soul” (ibid).

Again we see the dramatic difference between Aristotle’s modest experience-oriented and biologically grounded emergent notion of soul, and the grand metaphysical or divine pre-existent intellective soul posited by Plotinus.

“If the higher soul does not descend, if only its emanated dynamis is mixed with the body, how should we understand Plotinus’ words that the soul ‘leaps’ towards its own body? The answer is that this motion is what constitutes the soul qua soul, in its difference from the Intellect, or again that by which noēsis is modified into dianoia. Indeed, dianoia is the result of the encounter of intellective thought with time. It deploys the immediacy and totality of intuition into successive moments, to respond to the demands of the body, of action, and of a life diffracted by temporality (Enn. III.7[45].11). Thus, it must be considered “the sign of a diminishment of the Intellect” (Enn. IV.3[27].18.1–7)” (ibid).

Here we have a major source for all the arguments about whether intellect should be conceived as originally immediately intuitive or as originally discursive. Many people read Aristotle as if his notion of intellect were the intuitive one that Plotinus articulates explicitly. I think Aristotle is closer to Kant and Hegel’s position that intellect is inherently discursive, and that unifying intuitions only come about as the result of processes of synthesis.

“This movement seems to attest an oscillation between two conceptions of the subject: the reflexive subject and the subject of attribution (the logical or ontological substrate). What in fact appears, however, is that once again the reflexive subject – the hēmeis – does not allow itself to be reduced to the subject of attribution…. In this irreducibility of the hēmeis to the various levels of the soul, we may see an effect of Plotinus’ discovery of the difference between subject-consciousness and subject-substrate” (p. 317).

Here indeed we have the root of modern notions of “the subject” as consciousness. This same gap that Aubry speaks of is what leads Augustine to deny that the soul, spirit, or mind is to be identified with a subject as substrate.

“Consciousness is therefore not so much constitutive of identity as it is a condition for identification. We are not what we are aware of: quite the contrary, we become what we become aware of. If the reflexive question ends up in the acknowledgement of a duality, becoming aware, for its part, is equivalent to the choice of an identity” (p. 320).

For Plotinus, consciousness in itself is not a foundation for personal identity, as it is in Descartes and Locke. Instead, Aubry locates the basis of individuality for Plotinus in the “separated” soul.

The idea that we make a sort of primordial choice of what kind of being we are is unprecedented.

“[T]he constant activity within us of the separated soul is the necessary condition for such everyday cognitive operations as judgment…. It is in the latter — identical to the pure ousia, that is, the separated soul — that the foundation of individuality resides, together with the most intense life and an unalterable happiness” (p. 321).

The suggestion that the separated soul is involved in judgment is new to me, and intriguing. This makes it seem not so “separated” after all.

“Plotinus, for his part, is able to conceive both the permanent, impersonal subject and the
ethical subject defined as what makes the choice of its identity” (ibid).

New State Not a Change?

“Of all cases it would be most natural to suppose that there is alteration in figures and shapes, and in states and in the process of acquiring and losing these; but as a matter of fact in neither of these two cases is there alteration” (Aristotle, Physics book VII ch. 3, Collected Works, Barnes ed., vol. 1, p. 412).

What the translator calls a matter of fact, I would call a matter of terminology. All specialties tend to develop their own terminology, and philosophers do likewise. Aristotle uses many Greek terms with meanings that were already specialized in his day. Modern disciplines and common speech have evolved their own choices using different criteria.

“[T]here is alteration only in things that are said to be affected in their own right by sensible things…. For when anything has been completely shaped or structured, we do not call it by the name of its material: e.g. we do not call the statue bronze or the candle wax or the bed wood, but we use a paronymous expression and call them brazen, waxen, and wooden respectively. But when a thing has been affected or altered in any way we still call it by the original name: thus we speak of the bronze or the wax being fluid or hard or hot…, giving the matter the same name as the affection” (ibid).

Aristotle makes his usual semantic distinction between the matter, the form, and the composite of both. He wants to specialize the term that is translated as “change” or “alteration” to apply only to the matter, and to use different locutions with regard to the form and the composite.

“Again, states, whether of the body or of the soul, are not alterations. For some are excellences and some are defects, and neither excellence nor defect is an alteration: excellence is a perfection (… since it is then really in its natural state: e.g. a circle is perfect when it becomes really a circle and when it is best), while defect is a perishing of or departure from this condition. So just as when speaking of a house we do not call its arrival at perfection an alteration…, the same holds good in the case of excellences and defects and of the things that possess or acquire them” (ibid).

As we might also anticipate, he strongly emphasizes a teleological and normative perspective on these matters.

“Further, we say that all excellences depend on particular relations. Thus bodily excellences such as health and fitness we regard as consisting in a blending of… elements in due proportion, in relation either to one another within the body or to the surrounding; and in like manner we regard beauty, strength, and all other excellences and defects. Each of them exists in virtue of a particular relation and puts that which possesses it in a good or bad condition with regard to its proper affections” (pp. 412-413).

Most fascinating of all is this emphasis on particular relations. Good and bad conditions are explained in terms of these.

“Since, then, relatives are neither themselves alterations nor the subjects of alterations or of becoming or in fact of any change whatever, it is evident that neither states nor the process of losing and acquiring states are alterations, though it may be true that their becoming or perishing, like that of form and shape, necessarily involves the alteration of certain other things…. For each defect or excellence involves a relation with those things from which the possessor is naturally subject to alteration: thus excellence disposes its possessor to be unaffected or to be affected thus and so, while defect disposes its possessor to be affected or unaffected in a contrary way” (p. 413).

Relations in themselves are static abstractions of conditions. But some of the things involved in these relations are subject to change or alteration. This is a sophisticated way of approaching the matter.

“And the case is similar in regard to the states of the soul, all of which too exist in virtue of particular relations…. Consequently these cannot be alterations either, nor can the process of losing and acquiring them be so, though their becoming is necessarily the result of an alteration of the sensitive part of the soul, and this is altered by sensible objects…. Consequently, although their becoming is accompanied by an alteration, they are not themselves alterations” (ibid).

States of the soul are to be viewed in this relational way. Their becoming is said to be accompanied by an alteration, not itself to be an alteration.

“And again, the states of the intellectual part of the soul are not alterations; nor is there any becoming of them. For the possession of knowledge most especially depends on a particular relation” (ibid).

Knowledge also “most especially” involves being in a particular relation. It is not just the possession of some content.

“It is evident, then, from the preceding argument that alteration and being altered occur in sensible things and in the sensitive part of the soul and, except accidentally, in nothing else” (p. 414).

Aristotle on Explanation

Book 1 chapter 1 of Parts of Animals provides an overview of Aristotle’s perspective on explanation in general. It is a nice synthetic text that brings together many of Aristotle’s core concerns, and shows his vision of how natural science ought to fit in with broader philosophy.

He begins by distinguishing between mere acquaintance with an area of study and being educated in it. “For an educated [person] should be able to form a fair judgment as to the goodness or badness of an exposition” (Complete Works, Barnes ed., vol. 1, p. 994). This seems to apply to any subject whatsoever.

Next he raises the more specific question of method. “It is plain then that, in the science which inquires into nature, there must be certain canons, by reference to which a hearer shall be able to criticize the method of a professed exposition, quite independently of the question whether the statements made be true or false” (ibid).

Continuing to emphasize the critical thinking that is the mark of an educated person, he makes it explicit that some of the most important questions about a subject are what I would call second-order questions, having to do with how we ought to approach the matter at hand. The educated person will give due emphasis to these, rather than naively rushing to deliver judgments on questions of fact.

“Ought we, for example (to give an illustration of what I mean) to begin by discussing each separate substance — man, lion, ox, and the like — taking each kind in hand independently of the rest, or ought we rather to lay down the attributes which they have in common in virtue of some common element of their nature? For genera that are quite distinct present many identical phenomena, sleep, for instance, respiration, growth, decay, death, and other similar affections and conditions…. Now it is plain that if we deal with each species independently of the rest, we shall frequently be obliged to repeat ourselves over and over again; for horse and dog and man present every one of the phenomena just enumerated” (ibid).

The educated person looks for explanations, not just facts or correspondences. The specific “dogginess” of a dog, for example, does not explain its sleeping, breathing, and so on. Instead these activities, which it shares with many other animals, are explained by natures common to all of them.

Further, the kind of method Aristotle commends to us is not a matter of following recipes by rote. Instead, it is a thinking approach that involves persistently following the thread of explanations wherever it leads.

“So also there is a like uncertainty as to another point now to be mentioned. Ought the student of nature follow the plan adopted by the mathematicians in their astronomical demonstrations, and after considering the phenomena presented by animals, and their several parts, proceed subsequently to treat of the causes and the reason why; or ought he to follow some other method? Furthermore, the causes concerned in natural generation are, as we see, more than one. There is the cause for the sake of which, and the cause whence the beginning of motion comes. Now we must decide which of these two causes comes first, which second. Plainly, however, that cause is the first which we call that for the sake of which. For this is the account of the thing, and the account forms the starting-point, alike in the works of art and in works of nature. For the doctor and the builder define health or house, either by the intellect or by perception, and then proceed to give the accounts and the causes of each of the things they do and of why they should do it thus” (p. 995).

He raises the question of which kind of cause comes first, because he wants to suggest a different answer from that of the pre-Socratic “physicists” who attempted to explain everything by properties of different kinds of matter. Elsewhere he says that Plato and the atomist Democritus (whose writings are lost) did better than others at following the thread of explanation, but he considers the elaborated account of ends or “that for the sake of which” to be one of his own most important contributions.

Notably he only mentions two kinds of cause here, rather than the classic four. Similarly, there are passages in other texts where he lists a different number of categories than the canonical ten from the Categories. Later authors often viewed things like causes and categories in a reified, univocal way, as susceptible to exact enumeration. But for Aristotle, these are abstractions from a concrete reality that comes first, to be wielded in a context-sensitive way, so the canonical enumerations are not absolute.

Aristotle’s understanding of the “beginning of motion” is different from that promoted by early modern physics. Conventionally in the reading of Aristotle, the “beginning of motion” is associated with the efficient cause, and these two terms are understood in a somewhat circular way, which is really informed by some broadly intuitive sense of what a “beginning” of motion is. Early modern writers assumed that this “beginning” must be some kind of immediate impulse or force. Aquinas associated it with God’s act of creation and with the free acts of created beings. For Aristotle himself it is neither of these.

My best reading of efficient cause is that it is the means by which an end is realized. In many cases the end is realized not by just one means but by a hierarchy of means (e.g., art of building, carpenter, carpenter’s hammer, hammer’s blow). Aristotle and the scholastics emphasized the top of such hierarchies (e.g., the art of building for Aristotle; God or some metaphysical principle for the scholastics), whereas the early moderns emphasized the bottom (e.g., the hammer’s blow), akin to the proximate cause of concern to liability lawyers. For Aristotle, the art of building and not the hammer’s blow is the true “beginning” of the motion of house construction, because it provides the guiding thread of explanation for the whole process of building the house. But even the art of building is still just a means that gets its meaning from the reasons why we would want to build a house in the first place.

He continues, “Now in the works of nature the good and that for the sake of which is still more dominant than in works of art, nor is necessity a factor with the same significance in them all; though almost all writers try to refer their accounts to this, failing to distinguish the several ways in which necessity is spoken of. For there is absolute necessity, manifested in eternal phenomena; and there is hypothetical necessity, manifested in everything that is generated as in everything that is produced by art, be it a house or what it may. For if a house or other such final object is to be realized, it is necessary that first this and then that shall be produced and set in motion, and so on in continuous succession, until the end is reached, for the sake of which each prior thing is produced and exists. So also is it with the productions of nature. The mode of necessity, however, and the mode of demonstration are different in natural science from what they are in the theoretical sciences [e.g., mathematics]…. For in the latter the starting-point is that which is; in the former that which is to be. For since health, or a man, is of such and such a character, it is necessary for this or that to exist or be produced; it is not the case that, since this or that exists or has been produced, that of necessity exists or will exist. Nor is it possible to trace back the necessity of demonstrations of this sort to a starting-point, of which you can say that, since this exists, that exists [as one might do in mathematics]” (ibid).

In Aristotle’s usage, “nature” applies to terrestrial things that are observably subject to generation and corruption. He earlier referred to astronomical phenomena like the apparent motions of the stars and planets as “eternal” because on a human scale of time, these are not observably subject to generation and corruption. For Aristotle, absolute necessity could only apply to things that are absolutely unchanging. We may have a different perspective on astronomy, but that does not affect the logical distinction Aristotle is making. His key point here is that things subject to generation are not subject to absolute necessity. Leibniz took this a step further and argued that hypothetical necessity is the only kind there is. Kant, in arguing that hypothetical and disjunctive judgment (“if A then B” and “not both A and B“) are more fundamental than categorical judgment (“A is B“), made a related move.

Hypothetical necessity has a particular form that is worth noting. As Aristotle points out in the quote above, under hypothetical necessity “it is not the case that, since this or that exists or has been produced, that of necessity exists or will exist”. To give a positive example, hypothetical necessity says that to continue living, we must eat. But it does not in any way dictate a particular series of motions that is the only way this can be accomplished, let alone the whole series of eating-related actions throughout one’s life. Neither does it dictate that we will eat in any particular instance.

How we meet a particular need is up to us. The reality of this flexibility built into nature is all we need to explain freedom of action. Humans can also affirmatively embrace commitments and act on them; that too is up to us. Freedom is not an arbitrary or supernatural power; it simply consists in the fact that nature is flexible, and many things are up to us.

Aristotle contrasts the way a thing is naturally generated with the way it is. “The best course appears to be that we follow the method already mentioned — begin with the phenomena presented by each group of animals, and, when this is done, proceed afterwards to state the causes of those phenomena — in the case of generation too. For in house building too, these things come about because the form of the house is such and such, rather than its being the case that the house is such and such because it comes about thus…. Art indeed consists in the account of the product without its matter. So too with chance products; for they are produced in the same way as products of art” (pp. 995-996).

“The fittest mode, then, of treatment is to say, a man has such and such parts, because the essence of man is such and such, and because they are necessarily conditions of his existence, or, if we cannot quite say this then the next thing to it, namely, that it is either quite impossible for a man to exist without them, or, at any rate, that it is good that they should be there. And this follows: because man is such and such the process of his development is necessarily such as it is; and therefore this part is formed first, that next; and after a like fashion should we explain the generation of all other works of nature” (p. 996).

This way of reasoning backwards from an essence to its prerequisites is complemented by the fact that for Aristotle (and Plato) essences themselves are a prime subject of investigation, and not something assumed. “Begin with the phenomena”, he says.

Many 20th century philosophers have objected to presumptuous talk about the “essence of man”, and to any explanation in terms of essence. But these objections presuppose that the essence is something assumed, rather than being an object of investigation as it clearly was for Plato and Aristotle. Here also it is needful to distinguish between what we might call the distinguishing essence of humanity used to pick out humans — e.g., “rational/talking animal” — and what Leibniz later called the complete essence of each individual. Clearly also, the parts of the human body do not follow directly from “rational/talking animal”, but from many other attributes “presented in the phenomena”. It turns out that humans share these attributes with other animals, and they can therefore be conceptualized as attributes of common genera to which we and those other animals belong.

Because essences themselves are a prime subject of investigation and are ultimately inferred from phenomena, the kind of teleological reasoning Aristotle recommends always has a contingent character, which is how it naturally accounts for what the moderns call freedom. This contingency is built into in the “hypothetical” character of hypothetical necessity.

“Does, then, configuration and color constitute the essence of the various animals and their several parts? For if so, what Democritus says will be correct…. And yet a dead body has exactly the same configuration as a living one; but for all that it is not a man. So also no hand of bronze or wood or constituted in any but the appropriate way can possibly be a hand in more than name. For like a physician in a painting, or like a flute in a sculpture, it will be unable to perform its function” (p. 997).

Aristotle was the historic pioneer of “functional” explanation. Here he insists that the essences of living beings and their parts must be understood in terms of their characteristic activities. This development for the sake of biology parallels the deeper development of the meaning of “substance” in the Metaphysics as “what it was to be” a thing, and as actuality and potentiality.

“If now the form of the living being is the soul, or part of the soul, or something that without the soul cannot exist; as would seem to be the case, seeing at any rate that when the soul departs, what is left is no longer an animal, and that none of the parts remain what they were before, excepting in mere configuration, like the animals that in the fable are turned into stone; if, I say, this is so, then it will come within the province of the natural scientist to inform himself concerning the soul, and to treat of it, either in its entirety, or, at any rate, of that part of it which constitutes the essential character of an animal; and it will be his duty to say what a soul or this part of a soul is” (ibid).

Here it is important that we consider soul in the “phenomena first” way that Aristotle develops it.

“What has been said suggests the question, whether it is the whole soul or only some part of it, the consideration of which comes within the province of natural science. Now if it be of the whole soul that this should treat, then there is no place for any philosophy beside it…. But perhaps it is not the whole soul, nor all of its parts collectively, that constitutes the source of motion; but there may be one part, identical with that in plants, which is the source of growth, another, namely the sensory part, which is the source of change of quality, while still another, and this is not the intellectual part, is the source of locomotion. For other animals than man have the power of locomotion, but in none but him is there intellect. Thus it is plain that it is not of the whole soul that we have to treat. For it is not the whole soul that constitutes the animal nature, but only some part or parts of it” (p. 998).

Aristotle’s opposition to treating the soul as a single lump reflects his overall functional, activity-oriented, and phenomena-first approach.

“Again, whenever there is plainly some final end, to which a motion tends should nothing stand in its way, we always say that the one is for the sake of the other; and from this it is evident that there must be something of the kind, corresponding to what we call nature” (ibid).

Overall teleology always has to do with tendencies, not absolute determinations. He begins to wrap up this introduction by giving another example of the hypothetical necessity whose concept he pioneered.

“For if a piece of wood is to be split with an axe, the axe must of necessity be hard; and, if hard, must of necessity be made of bronze or iron. Now in exactly the same way the body, since it is an instrument — for both the body as a whole and its several parts individually are for the sake of something — if it is to do its work, must of necessity be of such and such a character, and made of such and such materials.”

“It is plain then that there are two modes of causation, and that both of these must, so far as possible, be taken into account, or at any rate an attempt must be made to include them both; and that those who fail in this tell us in reality nothing about nature” (p. 999).

Again, the two modes here are “that for the sake of which” and the phenomena associated with generation. Considering either of these in isolation yields an incomplete understanding, as we see respectively in bad scholasticism and bad empiricism.

“The reason why our predecessors failed to hit on this method of treatment was, that they were not in possession of the notion of essence, nor of any definition of substance. The first who came near it was Democritus, and he was far from adopting it as a necessary method in natural science, but was merely brought to it by constraint of facts. In the time of Socrates a nearer approach was made to the method. But at this period men gave up inquiring into nature, and philosophers diverted their attention to political science and to the virtues that benefit mankind” (ibid).

Socrates and Plato initially pioneered the notion of “that for the sake of which”, but in turning away from the phenomena of generation and becoming, they gave it a somewhat one-sided character.

The subtle way in which Aristotle wields the concept of essence avoids treating it as an absolute, or as something strictly univocal. In any given context, there is a clear relative distinction between essence and accident, but the distinction is not the same across all contexts. Hypothetical necessity provides the mechanism by which what is “accident” at one level of analysis can be incorporated into “essence” at another level.

The Human in Siger of Brabant

Those whom modern scholars called Averroists were supposed to be unoriginal, dogmatic followers of Averroes. This turns out to be as inaccurate as the supposition that the Latin scholastics as a whole were unoriginal, dogmatic followers of Aristotle.

At issue here is what it is to be human, and in particular how the difficult Aristotelian concept of “intellect” relates to human beings. There were not just two but a wide variety of nuanced and well-argued positions on this.

Among the so-called Averroists, Siger of Brabant (1240-1280) is the best known name, but no full book has yet been devoted to his work. According to Alain de Libera, in his later works Siger developed original responses to Thomas Aquinas’ famous critique of Averroes.

Siger argued against Aquinas that the act of thought is not purely immanent but simultaneously immanent and transitive. That is to say, for Siger it is immanent in the human, but transitive in the separate intellect. While affirming a “separate” intellect, Siger emphasized against Aquinas that the total act of thinking is attributable to the whole human, and not just to the human’s intellective soul. Intellect is an “intrinsic operation” in the human that in a way does, and in a way does not, make it the “substantial form” and perfection of a material body. According to Siger, Aquinas’ claim that the intellective soul unequivocally is the substantial form of the body cannot be reconciled with Aquinas’ other claim that intellect as a power of the intellective soul is entirely independent of the body. Siger adopts Albert and Thomas’ term “intellective soul”, but for Siger only the animal and vegetative soul are united with the body in being. Intellective soul is naturally united with the body in operation but not in being, whereas Aquinas says they are united in being.

According to de Libera, Siger in his Questions on the Book of Causes argues that the form of the human is not simple, but is rather a composite comprising an intellect that “comes from outside” (in Aristotle’s phrase), and a vegetative and sensitive substance that is “educed from the power of matter” (de Libera, Archéologie du sujet vol. 3 part 1, p. 411, my translation). Intellect is said by Siger to be a “form subsistent in itself”. It is not a “substantial form” in the proper sense, which would imply that it was inherent in the human body. It is not in the body “as in a subject”. However, intellect has need of the human body (specifically, the phantasms of the imagination) as an object, and intellect is in turn attributable to the human as a whole, though it is not reducible to the biological organism. Intellect for Siger is neither the inherent form of the human nor a separate, external mover of the human, but a separate form with an operation that is intrinsic to the whole human, in which it participates by composition.

De Libera remarks in passing that the act of thought owes more to intelligible objects than to “intellect”. I would suggest that it is through language and culture and ethical practice that Aristotelian intellect “comes to us from outside”. We talking, encultured animals then acquire a spiritual essence that comes to be intrinsic to us, through our ethical practice, in which acquired intellect and animal imagination cooperate.

According to de Libera, for Siger “The ‘intelligent whole’ is composed of many psychic parts, which are not of the same nature, or of the same origin, or of the same ontological status” (p. 362).

Siger objects that Aquinas’ notion of intellect as united with the body in being “makes the act of thought a perfection of matter” (ibid). This makes the body intellect’s “subject of inherence”. But at the same time, applying Thomas’ own axiom that nothing is accomplished by a power separated from itself, Siger reproaches Thomas for being unable to account for “the integrality of the known” (p. 378), and specifically the knowledge of material things.

For Aquinas, establishing that there is an operation proper to the soul is essential to the possibility of the soul’s existence independent of the body, and thus to his philosophical argument for personal immortality. But Siger argues that in making intellect an operation proper (i.e., uniquely attributable) to the soul, Aquinas implicitly negates its attributability to the whole human. Intellection for Siger is “an operation common to the human composite as an integral whole” (p. 377). In other words, I think with my whole being, not just my “mind”.

De Libera concludes that Siger does preserve the possibility of personal immortality, which was a principal concern of Averroes’ critics. However, he finds that the texts do not support the claims of some recent scholars that Siger in his later works abandoned “Averroism” in favor of Thomism.

The phrase “form subsistent in itself”, according to de Libera, does not have the same meaning for Siger that it does for Thomas. Albert the Great had analyzed three logical possibilities for an “intermediate” kind of form that is neither fully separate nor inseparable from matter. According to de Libera, Siger’s work is consistent with this. Siger aimed at a mean between a Platonist excess of separation between form and matter, and what he perceived as a Thomist excess of union with respect to so-called substantial forms. De Libera does find, however, that Siger, like other authors, is too anxious to simplify the issues at stake, and that he goes too far in identifying the position of Aquinas with that of Alexander of Aphrodisias, who was regarded as having a “materialist” view of the human soul. He also says Siger goes too far in reducing Aquinas’ notion of form to the simple analogy of a stamp in wax.

De Libera meanwhile also raises doubts about Aquinas’ insistence on the absence of any intermediary between the intellective soul and the body. He notes that in a very different context, the Franciscan Augustinian Peter Olivi argued that the intellective soul is united with the body via the intermediary of the sensitive soul. Olivi’s position was rejected by the Council of Vienna in 1312.

De Libera accepts the notion of “substantial form” as genuinely Aristotelian, but appears to endorse the argument of Bernardo Carlos Bazán that Aquinas’ notion of intellective soul gives it a privileged ontological status that makes it more than a substantial form. According to Bazán, Aquinas’ anthropology from the very start goes beyond the Aristotelian hylomorphism that Thomas generally endorses. The form of a human in Aquinas — unlike anything in Aristotle — is such that it could not be the result of any natural generative process, but could only be created by God. Siger comes across as closer to Aristotle.

De Libera notes that in the wake of the English theologian Thomas Wylton (1288-1322), later so-called Averroists “invested massively” in a distinction between an inherent form and an assisting form, and regarded human intellect as an “assisting form”. (See also “This Human Understands”; “This Human”, Again; Averroes as Read by de Libera.)

Aquinas on the Soul

Lately I’ve repeatedly mentioned Thomas Aquinas (1225-1274), and I feel some additional due diligence is in order. Though I have browsed his major works, I am assuredly no Aquinas scholar, so I want to tread carefully. This is an exploration, and conclusions may be revised.

My currently interrupted arc treating Alain de Libera’s Archaeology of the Subject has brought to light some unfamiliar suggestions regarding Aquinas’ role in the formation of the modern concept of action as a central explanatory term. Act, action, and actuality are three distinct things in Aristotle, and they seem to be three different distinct things in Aquinas. We have to be careful that all these distinctions are not confused. So, I am embarking on a little detour to get a clearer sense of what they specifically mean in Aquinas.

The most famous theologian of the Catholic church, Aquinas is a very substantial figure whose work has given rise to diverse interpretations. His principal concern was what is called revealed theology, which properly speaking is outside my scope here, but he was perhaps best known (and initially controversial) for his philosophical theology, and for fusing discourses of theology and philosophy. Without ever losing sight of things he considered to be known by faith, he gave an unprecedented place to philosophical arguments in his theological works, and also developed a highly original purely philosophical theology, which he held to independently point in the same direction as his revealed theology.

Contrary to the myth that the Latin middle ages were dogmatically Aristotelian, the place of Aristotelian learning and the social status of philosophy in Aquinas’ lifetime were actually quite precarious, encountering widespread opposition from religious conservatives. Were it not for the conciliatory work of Aquinas and its eventual acceptance by the Church, conservatives might have succeeded in rolling back the great cultural advances that began in the 12th and 13th centuries with the influx of Arabic, Hebrew, and Greek learning into the hitherto rather barbarous world of Latin-speaking Europe. If I often sound critical of Aquinas and disagree with his extraordinarily original redeployment of some key Aristotelian terms, that should be taken in the context of this larger historical debt.

On the question of the soul, Thomist scholar Ralph McInerny explains in the Stanford Encyclopedia of Philosophy that Aquinas in questions 75 and 76 of the first part of Summa Theologica distinguishes between a substance and a “subsistent”. He also develops a concept of a being’s actus essendi or “act of existence”. Both of these details — which have no precedent in Aristotle — are new to me. This is the same part of Summa Theologica that de Libera was focusing on.

The human soul for Aquinas is not an independent spiritual substance as an angel would be; rather it is the subsistent substantial form and formal principle of an embodied human being. It makes the human what she is, but is not complete in itself. As a principle of a nature, it has no nature of its own, and is not a substance in its own right. Its nature is to be the formal element of a complete (embodied) substance.

According to McInerny, Aquinas stresses that “the soul exists in a living being as the substantial form of an animal”. Socrates as a human has all the vital activities of a living animal. For Aquinas none of these are distinctive activities of the soul itself, because they are involved with bodily functions. On the other hand, the intellect of Socrates is said by Aquinas to be a distinctive activity or “operation” of Socrates’ soul itself that involves no corporeal organ, and this operation is said to be able to exist independent of the body.

Aquinas acknowledges this to be an unnatural state, since the soul is not complete in itself. But he holds that it is enough to establish that the human soul has an operation that does not depend on a bodily organ, in order to show that the human soul is an incorporeal subsistent that can exist independent of the body. Souls of nonhuman animals have no nonbodily operation, and therefore are not immaterial subsistents. At the same time, the intellectual soul of a human is distinguished from an angel precisely because it is the substantial form of an animal.

Taking it as established that Socrates as an embodied human being is not the same as the soul of Socrates, Aquinas according to McInerny argues that Socrates and his soul nonetheless are both “subjects” of one identical activity or operation. Intellect is an activity of Socrates’ soul that is equally an activity of Socrates the complete human. Aquinas holds that for an animal with an intellectual operation, the intellectual soul and the animal (and vegetable) soul are one and the same.

McInerny summarizes, “In the case of other animals it is the animal itself, the living substance, that is the subject of the act of existence, and both soul and body have existence through the substance. Here in the human case, the soul is said to be the subject of the act of existence because it has its own operation.”

Rationality — or acting knowingly and willingly — “is the distinctive form that intelligence takes in human beings as animals. Rationality involves the back and forth of argument moving from one thing known to another, and advancing in knowledge by such movement. Thus, for Thomas, while angels and God can be said to be intelligent, they are not rational.”

“Reason does not distinguish us from animals; it distinguishes us as animals. So according to Aquinas, while it is true that the activities of intellect and will are not the actualities of any physical organs, they are nonetheless the activities of the living human animal. It is Socrates the animal who knows and wills, not his mind interacting with his body.”

If acting knowingly and willingly has the plain ordinary meaning it does in the discussions of responsibility in Aristotle’s Nicomachean Ethics, I could fully subscribe to each individual statement in the last two paragraphs. This has no fancy metaphysical prerequisites. But a premise about acting knowingly and willingly does not seem to me to justify a conclusion about the activities of knowing and willing as such. Nor do I think that knowing and willing is the proper activity of Aristotelian nous or “intellect”.

(I think even Averroes would agree that it is Socrates the animal who “knows and wills”, in the sense that those terms have in Aristotle’s ethics. I think he would like the distinction between intellect and the reason of the rational animal. But I think Averroes would go on to specify that knowing and willing and rationality attach to the animal by way of a development of the animal’s “imagination”. I would myself also emphasize the role of language and ethos.)

I am not sure about calling intellect an operation “of the soul itself”, or indeed an “operation” at all. But I truly have no idea what an “act of existence” would be in Aristotelian terms. Plotinus spoke of the natural act of a being as its good. But “act of existence” to my ear suggests something more like Spinoza’s conatus or effort to exist, which seems at least in part to have a Stoic heritage. Neither of these meanings seems applicable to God. But then, neither is it yet clear to me how the “act of existence” of a created being is related to Aquinas’ notion of the pure act of pure Being, which I have understood as conferring the existence of beings.
