Potentiality in the Stars

“Lambda 2 marks the irruption in Metaphysics Lambda of the notions of dunamis and energeia, at the same time as the passage from doxographic examination to the thetic moment” (Aubry, Dieu san la puissance, 2nd ed., ch. 5, p. 165, my translation throughout). Aristotle’s distinctive concepts of potentiality and act had been absent from chapter 1’s preliminary survey of the opinions of others, but as soon as he begins to elaborate his own proper theses, they reappear.

“Lambda 2 proceeds also to a substitution: that of the couple dunamei/energeia for the triplicity of matter and the contraries. It is necessary to note — and this is an essential point — that here in what is their first occurrence in Lambda, these notions intervene straightaway under their dative form, and as a division of being: ‘For, since being is double, everything changes from being in-potentiality to being in-act’…. the dative form marking the ontological sense more specifically” (ibid).

Aristotle is not abolishing matter in the modern sense. Replacing stuff with a modality like potentiality would seem rather odd, but that is not what is occurring here. Hylomorphism means that any kind of “stuff” must already be body — and thus for Aristotle must be a “composite” of form and matter. He never treats form and matter as discrete parts of a thing, and repeatedly insists that they can only be separated by abstraction. Aristotelian matter in itself has always struck me as principally specifying a kind of primordial adverbiality and relationality involved in any embodiment.

Here he is moving yet further away from the “grammatical prejudice” of an underlying thing in which properties inhere. The whole dialectical development of the concept of “substance” (ousia) in the Zeta-Eta-Theta sequence and book Lambda precisely involves moving beyond the notion of something “underlying” that we naturally begin with in thinking about how things persist through time. Here we see a related movement beyond the abstraction that Aristotle calls matter, which was the initial candidate for something underlying.

“Lambda 2 takes metabole [change] as its primary object. It proposes an analysis appropriate to all kinds of change, and in particular both substantial change and change of position…. More precisely, it is a matter of identifying the principles common to all sensible and movable substances, whether they are eternal [astronomical] or corruptible [earthly]. For it is the intervention of the notion of dunamei and its substitution for that of matter, that makes possible this unification of the principles of sensible substance” (ibid).

“The text finds a precise parallel in book I of the Physics, where the same three formulae succeed one another: the contraries and their subject; matter, form, and privation; and finally, the formula according to power and act, kata ten dunamin kai ten energeian. Nonetheless, in Physics I the last is mentioned as having been treated elsewhere with more precision. Still it reappears at the end of that book, in the context of a critique of the Platonic theory of matter: Plato erroneously identifies matter with non-being, with evil and privation…. That which desires the positive contrary must be matter, as distinct from one and the other contrary. Matter must therefore be distinguished from privation: the latter is in itself the principle of corruption. On the other hand, if we consider it according to power, kata ten dunamin, matter is unengendered and incorruptible” (pp. 165-166).

“The last lines of book I of the Physics considerably clarify chapter 2, but also 3, of Lambda, in that they designate two distinct modes of approach to the material and formal principles: the perishable forms are in effect called ‘physical’, and the study of the others is deferred to first philosophy. But this distinction applies also to matter: in fact, we distinguish equally between corruptible matter and incorruptible matter. For unengendered and incorruptible matter is identified with matter considered kata dunamin, or according to a point of view that, without having been explicitly named, has nonetheless been distinguished from the physical point of view” (p. 166).

Modern physics and chemistry speak of an ultimate conservation of matter.

“The fact is that over the course of Lambda 2, the couple of in-potentiality and act is substituted for the triad of matter and the contraries. Thus change is no longer presented as the transition of matter from one contrary to another, but as a passage ‘from being in-potentiality to being in-act’. For to treat it thus is to underline, as the end of Physics I already has against Plato, that even in the case of generation, metabole does not have for its principle absolute non-being, but being in-potentiality. And it is also to underline, this time against [the Ionian philosophers of nature], that in-potentiality in its turn is for a determinate being” (pp. 166-167).

“But beyond these polemical stakes, the substitution of the couple of in-potentiality and act for the triad of matter and the contraries makes possible a formula of change that is valid for all the movable substances, whether they are corruptible or incorruptible” (p. 167).

“Thus conceived, kata dunamin or again dunamei, matter appears no longer as a physical component but as a metaphysical principle, valid as much for the corruptible sensibles as for the eternal sensibles” (ibid).

A component suggests something mutually exclusive with other components, while a principle affects the whole of something. Potentiality is neither a component nor an underlying thing.

This “marks a progress from Theta 8: in fact, there energeia is found attributed to the eternal sensibles, but dissociated from dunamis, since the latter was understood as the power of contradiction, and treated as definitional of the corruptible sensibles. Now we discover that it is not only act, but also in-potentiality that… admits an extension from the corruptible sensibles to the eternal sensibles” (ibid).

The “power of contradiction” would be a power to be or not to be something. Unlike earthly things, Aristotle sees the stars as moving in an unchanging way, and as not changing in their being in doing so. Since they are involved in motion from place to place, I was previously surprised by Aristotle’s remark in Theta 8 that seemed to say that eternal sensibles have no potentiality. Now we see that after all they do have potentiality, in the way that he has redefined it here.

Love’s Intellect

The main theme here is an unexpectedly close relation between love and a broadly Aristotelian notion of intellect. We will also see another perspective on the crucial Aristotelian concepts of potentiality and act, and perhaps shed further light on Aristotle’s telegraphic remarks about how we have knowledge of “privations” or negations of things.

I’ll be devoting two posts to the small pamphlet Intellect d’Amour (2018), introduced by the great contemporary scholar of medieval philosophy Alain de Libera, in which leading specialist in Averroes and Latin Averroism Jean-Baptiste Brenet translates an Italian essay by Giorgio Agamben, and presents a related essay of his own. This post deals with Agamben’s part.

While I have little sympathy for Agamben’s quasi-Heideggerian reduction elsewhere of “Western metaphysics” as a whole to a fundamental error for which Aristotle is supposedly to blame, his essay here is focused and interesting. The medieval Italian poet and philosopher Guido Cavalcanti (1255?-1300) — a close associate of and influence on the great Dante Alighieri, author of The Divine Comedy — is now generally understood to have been inspired by Italian Averroist philosophy (see Italian Aristotelianism). The dominant interpretation of Cavalcanti, however, has been that of Bruno Nardi, who emphasizes a fundamental discontinuity between Cavalcanti’s exaltation of love in both its spiritual and its erotic dimensions, and his Averroist views on intellect. Agamben, Brenet, and de Libera all seem to agree in turning this interpretation on its head.

Dante and Cavalcanti are both commonly associated with the historically shadowy group of poets known as the fedeli d’amore (love’s faithful). The fedeli were apparently influenced by the poetry and music of the troubadours, who developed the Western medieval tradition of courtly love, and also used it as a spiritual metaphor, somewhat along the lines of Plato’s Symposium. Sources of the troubadour tradition are disputed by scholars and likely were multiple, but an Arabic or specifically Sufi element has been repeatedly suggested.

Agamben’s essay points out that a particularly mysterious phrase bianco in tale obiettò cade (something like “white falls into this objection”) in Cavalcanti’s poem Donna me prega appears to be intended to recall the Latin cecidit albedo in exemplari in Averroes’ Long Commentary on Aristotle’s On the Soul. In the poem, Cavalcanti has just said that love cannot be understood in terms of vision.

Agamben notes that in the passage where the corresponding phrase appears in Averroes, Averroes is more broadly addressing how we know the privations of positive terms. In the context of vision, Averroes poses “blackness” as a privation of “whiteness”, somewhat like modern science calls blackness an absence of color. Agamben quotes de Libera’s remark in his partial French translation of Averroes’ work that “Every privation is effectively known negatively, by preliminarily positing something and then negating it” (p. 13, my translation throughout).

The “white” in Cavalcanti’s poem recalls the white by which the black is known as a privation. Following the passage Cavalcanti refers to, the Latin translation of Averroes says “And it is necessary that this faculty of knowledge perceives the privation in perceiving itself as being in potentiality, when it is in potentiality, since it perceives the one and the other of itself, that is to say being in potentiality and being in act. And such is the case with the material intellect” (quoted, p. 19).

Here we have among other things a fascinating connection between self-apprehension and negation. I imagine Hegel nodding in approval here.

“Averroes affirms that, in knowing obscurity, the material intellect knows itself insofar as it is in potentiality, and that, reciprocally, for the material intellect, to understand itself is equivalent to knowing obscurity and privation. One sole and same faculty — the material or possible intellect — knows obscurity and light (obscuritatem et lumen), power and act, form and its privation. As de Libera notes, this signifies that ‘privation is attached to the very essence of intellect’, and indeed also — the consequence is inevitable — that obscurity — non-thinking in act — is an integral part of intellect and is consubstantial with it ” (pp. 19-20).

Here I think also of Socrates’ comment that wisdom involves recognizing what we do not know. In a sense, this kind of recognition of privation is just as much a part of knowledge as any positive content.

“The idea that obscurity, which for him constitutes an essential part of the amorous experience, in no way implies an exclusion of knowledge, could not but fascinate Cavalcanti. On the contrary, since one sole and same faculty — the possible or material intellect, where love has its dwelling place — knows equally well the darkness and the light, equally well the form and its privation, having the amorous experience of obscurity thus also necessarily signifies having the experience of the pure power of intellect” (p. 20).

In passing, Agamben refers here to his major thesis in this essay, that the material intellect is where love has its abode for Cavalcanti. We also see an example of the Aristotelian thesis that rational knowledge of one of a pair of opposites necessarily entails knowledge of the other.

“In this perspective, it is possible to divide the philosophers into two great classes or families. According to the one group, what defines humans is the act of thinking, and the latter are indeed like the angels, always in the act of thinking; according to the others (the Averroist tradition in which Cavalcanti as well as Dante are inscribed by right), what defines humans is not the act, but the power of thinking (humans do not think continually, which is to say they think in an intermittent way — not sine interpolatione [without interpolation], as Dante says” (pp. 20-21).

In our thinking, we who are not pure act depend on this “power of thinking” that begins as something external to us.

Agamben recalls that Averroes calls the material intellect a fourth kind of being (neither form, nor matter, nor a composite). “It is this perception of its own obscurity by the material intellect, essentially divided in its being, which becomes for Cavalcanti the place of the experience of love” (p. 22). “If the attempt to think, apropos of the material intellect, the existence of a pure power as a fourth genus of being leads Averroism to an aporia from which it is not easy to escape, it nonetheless furnishes, and precisely through that, the elements of another conception of subject than that which has prevailed since Descartes…. Otherwise said, Averroism thinks the subject as the subject of a power, and not only of an act…. Averroes suggests that the material intellect should be considered more as a place… than as a matter” (p. 23).

Agamben’s language seems overly loose here, in that it blurs together act in an Aristotelian sense and agency in a modern sense, but he nonetheless makes an important point. The “Cartesian subject” is indeed commonly conceived more or less exclusively in terms of its agency in the modern sense. Both the mechanist and the voluntarist dimensions in Cartesian thought mitigate against taking the key Aristotelian concept of potentiality seriously (and conversely, taking potentiality seriously makes both mechanism and voluntarism untenable).

The modern notion of agency is distinguished by the fact that from the outset, it is conceived as not having any inherent relation to a contrasting term like potentiality, that would condition and limit it. By contrast, Aristotle only arrives at the thesis that there can be such a thing as pure act after a long dialectical development, starting from the cases where act is only analytically distinguishable from potentiality. The common modern approach short-circuits all of this. Aristotelian act and agency in the modern sense are thus two different things. But Agamben correctly points out that any finite “subject” that is the subject of a conditioning power (or capability, as Paul Ricoeur more felicitously puts it) will be fundamentally different from the modern stereotype of a one-sided subject-agent.

“The great invention of Cavalcanti, of Dante and the other poets of love, is to situate love in the possible intellect without reservation. As the song says, and for once clearly, the possibile intelletto is the subject — or the quasi-subject (come in subietto) — the loco [place] and the dimoranza [residence] (the mansio [house]) of the veduta forma [form seen] that produces love…. [L]ove (as the ‘form seen’, veduta forma, which gives birth to it) is in the possible intellect as in its proper place” (p. 24).

The thought here seems to be that the feeling of love follows from the apprehension of a form or image as having characteristics that make it in itself lovable. According to Agamben, for Cavalcanti and Dante, the possible aka potential aka material intellect is the “quasi-subject” of love. At the same time, the possible intellect is not so much a discrete entity as a “place” that is not really a discrete place either, but a kind of ubiquitous structural relation.

Agamben cites a line from Dante speaking of “women who have love’s intellect”. He comments, “[B]etween intellect and love the connection is essential” (ibid).

“The modern specialists, each convinced that they think with their own brain — when to all evidence they on the contrary think according to the common paradigms imposed by the doctrinal system in which they are inscribed — experience such distress before the Averroist theory of the unique intellect, that they do not understand what should nonetheless be evident, namely that the speculative node of the question, so to speak the experimentum crucis [cross test] of Averroism, does not consist in the division between individuals and intellect, but — once the division is affirmed — in their conjunction, which the Latin translators render by the technical terms copulatio and continuatio. In this conjunction between the unique material intellect and singular individuals, the essential mediating function is accomplished by the intentiones ymaginatae, that is to say the phantasms of the imagination” (p. 25).

“Nonetheless, not only does the imagination operate as an intermediary between individuals and the intellect, but it is also for Calvalcanti the object and at the same time the subject of amorous passion” (p. 26). “Cavalcanti and the poets of love take the coincidence between love and imagination so far that they personify the phantasms” (p. 27).

This is saying that imagination is both the object and the subject of love, as well as what individualizes intellect.

Agamben points out that Averroes strongly underlines Aristotle’s statement that only the combination of intellect and desire moves us. “It is this singular fusion between intellect, desire, and imagination that it is also necessary to understand in the ‘love’s intellect’ of Dante…. Love is not a substance, it is — as [Cavalcanti’s] song says in its overture — an ‘accident’ that indetermines the three substances intellect, imagination, and desire, and puts them fiercely in tension” (p. 29).

“[F]or intellection to be ‘acquired’ and become ‘proper’ to the individual, in effect it does not suffice that the forms be imagined, but it is necessary that they be desired and willed…. [T]he phantasm by desire makes the intelligible proper to the subject. Thought belongs to me because it has been imagined and desired” (p. 31).

“The great invention of Cavalcanti and the poets of love is to make love the place par excellence of the adeptio [acquisition] of thought by the individual” (p. 32).

Whom and what we love are of decisive importance to who we are, as well as to what we hold to be true.

Agamben notes that Dante also drew political consequences from his Averroist view of intellect. He quotes Dante’s treatise on monarchy: “Since the power of thought cannot be integrally and simultaneously actualized by a single human or by a single particular community […], it is necessary that there be in the human genus a multitude through which the whole power is in act” (p. 33, ellipses in original).

Dante’s universalist aspirations distinguish him from Cavalcanti, who was deeply involved in factional intrigue. For Dante, “‘our’… accompanies and precedes ‘me'” (p. 34).
