Ousia Energeia

Aristotle’s Metaphysics is arguably the single most important text in the history of philosophy, but even though on one level Aristotle’s writing is extremely clear and lucid, its deeper implications have been highly disputed. The great Iranian philosopher Avicenna is reported to have said that he read the Arabic translation of the Metaphysics 40 times without understanding it, and only began to understand after reading the commentary by Alfarabi. We are nearing the end of a long journey following what I think is a brilliantly innovative 21st century reading by Gwenaëlle Aubry. Here I’m covering the first half of her discussion of book Lambda chapter 7.

The title of this post is a phrase used by Aristotle to characterize the first cause. He distinguishes it as the ousia [“substance”] that, unlike other substances, simply “is” energeia [“act”]. The latter Greek term was coined by Aristotle, and the former was “substantially” redefined by him. I find it is best to put aside ordinary connotations of the English words for key philosophical terms like this (including “first cause”) — and to focus instead on the ways the philosopher himself uses them, along with what he says about them.

“Chapter 7 of book Lambda responds to the question, left in suspense, of the mode of relation of the first mover to the moved, and of the nature of its action. At the same time it exploits and deploys the ontological signification of energeia, designating in act the mode of being of the separate, and identifying it with the good and the end” (Aubry, Dieu san la puissance, 2nd ed., ch. 5, p. 184, emphasis added, my translation throughout).

“In so doing, it implies at the same time a distinction, absent from book Theta, between kinesis [motion] and energeia, the last being designated as the mode of being of the unmoved, even while maintaining a broad sense of energeia, understood not only as act and as a mode of being, but also as a certain activity (contemplation)” (ibid).

Aubry previously noted that Aristotle’s earliest use of energeia seems to have been in an ethical context. Here she points out that Aristotle is distinguishing between its better known physical sense (which already has a teleological element) and what she calls its ontological sense.

“The first lines of Lambda 7 mark a progress in relation to chapter 6, since they demonstrate not only the necessity of posing a principle that is act and not power in order to give an account of eternal motion, but also of that of thinking the first mover as unmoved” (ibid, emphasis added).

Within the context of Greek philosophy, the very idea of an unmoved mover is another extremely important Aristotelian invention. Plato speaks instead of a self-moving thing, thus postulating motion as an unexplained primitive attributed to something as a whole. He is not bothered by the unexplained primitive, because he sees becoming as fundamentally lacking intelligibility. For Aristotle on the other hand, motion ought to be explainable, and every explanation of motion also involves a passivity. To move in the colloquial English sense is always to be moved in Aristotle’s sense, by something, and we can give an account of this. It will turn out that the primary examples he gives of “movers” are the unmoved intelligible and desired things that serve to activate internal principles of motion in other things. But living beings such as animals also function as “moved movers”.

Aubry quotes Aristotle’s characterization of an unmoved mover as “being at the same time ousia and energeia” (p. 185). Aristotle makes a very compressed reference to his critique of Platonic “self-moving” in Physics book VIII. Anything we broadly call a “self” mover must be a moved mover, because it is implicitly moved by what it understands and desires. Any moved mover — and hence any self-mover — must be only an intermediary cause, and not an ultimate principle. Aristotle wants to very emphatically insist that the first cause is in the strict sense an unmoved mover, and not a self-mover in the broad sense that an animal is a self-mover. For him, any holistic “self-motion” necessarily involves the kind of mixture of activity and passivity that we attribute to an animal. Such a mixture is incompatible with the nature of the first cause.

“[I]t is because energeia is conceived here as ousia, and no longer as kinesis, that the first mover is unmoved” (ibid).

“This poses the question of how the unmoved can be the principle of movement. The demonstration this time proceeds in an indirect way: it consists in the premise according to which the desirable and the intelligible move [other things] without being moved, then in successive identifications, first of the real good with the desirable, then of simple and actual substance with the first intelligible, and finally of the first intelligible with the good. We then ought to conclude that the actual substance, itself already identified with the first mover, is identical with the intelligible and the good, and as such can move [other things] without being moved” (ibid).

She goes on to note that what allows these terms to be unified is really once again energeia, although at first it seems to be substance. This makes perfect sense, given the conclusions of book Eta.

“The unifying term of these identifications seems here to be that of substance. It is so nonetheless by the mediation of a double relation of anteriority: of substance itself, first of all, in the series of positive contraries; then, within substance, of substance that is simple and in act, haplo kai kat’energeian — or, more precisely, of substance that is simple insofar as it is said according to act. For it is this position of the preeminence of substance in the context of the series of intelligibles that justifies its identification not only with the good and the desirable, but with the better or that which is analogous to it. Thus it is once again the notion of energeia more than that of substance that appears as the conceptual mover of the demonstration, and as that from which the attributes of the principle can be deduced” (pp. 185-186, emphasis in original).

Just as Aristotle uses ousia or substance to explain our talk about being, he uses energeia or act to explain our talk about substance. And sometimes he even uses entelekheia or entelechy to explain our talk about act.

“Up to this point, Lambda 7 has established that the unmoved can be a mover, but not how it moves something else. Here again, the demonstration proceeds in an indirect way: it begins by establishing that there is also a final cause among unmoved things. In order to do this, we have to make precise what we mean by ‘final cause'” (p. 186).

“The text at this point poses a problem. Since antiquity, it has been reconstructed so as to coincide with parallel passages in Physics II and On the Soul II which, also relying on a pronominal distinction, distinguish between two senses of the final cause, that is to say to ou and to o, that which is envisaged and that for which something is — or, according to the traditional interpretation, the end of an action and its beneficiary. But neither of the senses thus distinguished can apply to the first mover: the latter cannot be conceived as the beneficiary of action, which would imply that it did not have its end in itself, and would thus be incompatible with its status as pure energeia. But it is equally difficult to conceive it as the end envisaged by action, since this would imply that the movement ends in it, or finds in it its term: the first mover would thus be the act and the end of eternal motion, and indeed of every moved being; thus conceived, the divine would be in sum the act of the world, or at least of the moved substances that make it up, whose separate existence would be explained only by the failure of their fusion with it” (pp. 186-187).

“The context of the distinction in On the Soul is nonetheless very close to that of the distinction of Lambda 7, since the text opposes on the one hand living things (plants and animals) considered as substances subject to the cycle of generation and corruption, and on the other hand the eternal and the divine…. Nonetheless, it does not aim to distinguish between an unmoved end and an end presupposing movement, but rather between an immediate and immanent end and a mediate and transcendent end. The first is identified with the soul, designated as being at the same time cause of motion, essence, and final cause…. The second is identified not with the divine itself, but with participation and community (koinonia) with it, and a community envisaged as continuous. Thus is explained the process of generation, which compensates for that of corruption: not being able to [persist indefinitely] as individuals, living things [persist] not in their numerical unity, but in the unity of their species. The object of their desire is thus not to be god but to participate in the divine, or in the mode of being that characterizes continuity and eternity. Or again, it is not to assimilate themselves to the divine form or the divine act, but rather to perpetuate their own form and act, in the way that the divine continually maintains its own” (p. 187, emphasis in original).

“But if read this way, as a distinction not between the end of action and its beneficiary, but between two kinds of end, the distinction in On the Soul seems reconcilable with that of Lambda 7, and to apply to the first unmoved mover: the latter should be understood neither as the immediate end of action nor as the one who attains that end, but as that which the moved substances aim at through their own proper ends” (pp. 187-188, emphasis added).

“The latter aim at no other end than themselves, and attain this immanent end by means of the different movements to which they are submitted, but through this end they aim also at the eternity and the necessity characteristic of the unmoved substance. As result, we can say that they are also moved by the unmoved, and again by the desire for unmovedness. We see that this interpretation agrees with the end of Lambda 7, as well as with Lambda 10’s reflection on the final cause and the good” (p. 188, emphasis added).

“The remainder of [Lambda 7] goes on precisely to mark the relation between unmovedness and necessity, at the same time as that between motion (even local) and contingency. This last point is the same that Theta 8 already underlined, but the demonstration relies no longer on the notion of dunamis understood as the power of contradiction, and indeed as the power to be or not-be, but on the notion of energeia. Unmovedness is deduced from this, and necessity in its turn from unmovedness. Here indeed, and for the first time, the ontological sense of energeia… excludes kinesis” (ibid).

She notes that Aristotle uses the grammatically dative from of energeia in the text here, which she has argued he consistently uses to distinguish what she calls the ontological sense of dynamis and energeia from their physical sense that is involved in the ordinary explanation of motion.

(I would add that this philosophical primacy of the dative form over the nominative in Aristotle is closely related to a perspective that puts adverbial phrases and relations ahead of nouns and verbs in the order of explanation. In fact, every noun or verb taken by itself is just a simple linguistic token that still has to be given an interpretation. No mere linguistic token by itself explains anything at all. By contrast, it is the non-simple character of relations — the fact that they already intrinsically “say something” about something — that gives them their fundamental role in interpretation and explanation.)

“If it is thus established that the unmoved can be an end…, it remains to know how it is, or to identify its proper mode of action, which is presented as valid for all final causes that exclude motion. Two words suffice to name this mode of action: hos eromenon [as being loved]. The hos does not introduce a metaphor, … but must be understood in the sense of ‘insofar as’: the unmoved mover moves without being moved, but ‘insofar as it is loved’. In its turn, the theme of eros has been prepared by the earlier reflection on the identity of the intelligible and the desirable, where it was said already that they move [other things] without being moved” (ibid).

“For the technical register that distinguishes between different species of desire, rational and irrational, is here substituted a broader term, eromenon. This term also has Platonic resonances: it evokes the amorous ascension of the Symposium, and recalls the figure of Eros, the daimon child of Penia and Poros, in whom are conjoined lack and abundance, absence and presence. Evoking Eros, nonetheless, Plato in the Symposium speaks of dunamis. Here, inversely, the erotic ascension has for its principle energeia. We see again in this point the rupture underlined in book capital Alpha, as in Lambda 6: to conceive the causality proper to the good, it is necessary to think it as a final cause, acting not as power but as act, and as the end of in-potentiality” (p. 189).

Aubry has consistently maintained that acting in the sense of having an effect is not reducible to the “action” of a power. All ordinary “action” is in reality a mixed form — an interaction — that includes an element of passivity. Pure act on the other hand is supposed to have an effect and to move other things, but without itself being involved in passivity. There is still an element of passivity in this case, but it is entirely on the side of the other things that are moved by what they understand and desire. Pure act for Aristotle is situated beyond the correlation of activity and passivity. Only where in-potentiality is also involved is there the ordinary interaction of activity and passivity that we experience in earthly happenings.

Rather than aiming to think pure presence, in the context of a human being even Plato is far more interested in mixed forms, as Paul Ricoeur has pointed out. Aristotle here takes up the Platonic theme of eros, while recasting it as an ascent toward pure act. But pure act is precisely not ever purely present to us. In the next post, we’ll see how Aristotle contrasts human life with the ideal life he attributes to the first cause.

Eternal Motion

Chapter 6 of book Lambda of Aristotle’s Metaphysics takes chapter 5’s unification of eternal and corruptible sensible substance as a starting point, and now inquires into the relation between sensible, movable substance as a whole and unmoved substance. We’ve been following the detailed development of Gwenaëlle Aubry’s provocative non-traditional interpretation of the distinctive features of Aristotle’s account.

“The simple and necessary substance is not needed in order to give an account of the substances that, insofar as they are mixed from act and in-potentiality, can either be or not be, but in order to give an account of movement insofar as it cannot not be. The first question for Aristotle is not ‘why is there being?’ but ‘why is there movement?’, or, more precisely, ‘why is there always movement?'” (Aubry, Dieu san la puissance, 2nd ed., ch. 5, p. 178, emphasis added, my translation throughout).

“Whereas the theology of omnipotence is a response to the question of the emergence of being, the theology of pure act in effect is a response to the question of the eternity of movement. The god of Aristotle thus provides a reason for the most manifest, for the most evident. It is not the ground — or the bottomlessness — of the mystery of being, more mysterious than the being it serves to explain, but the reason of the most immediate, most apparent phenomenon. Movement, in effect, is the first given” (ibid).

“[A]mong the different species of movement, the priority comes back to local movement. The latter is indeed anterior to genesis: ‘It is impossible that generation should be first’. Generation is only first in the order of the individual, since the latter must exist in order to move. But in order for it to come into being, it is necessary for another being to have preexisted it which was in movement, and the same for this last. Thus it is not movement that comes to be, but coming to be that presupposes an antecedent movement and being” (pp. 178-179, emphasis in original).

She quotes from Generation and Corruption book II chapter 10, “For it is far more reasonable that what is should cause the coming-to-be of what is not, than that what is not should cause the being of what is. Now that which is being moved is, but that which is coming-to-be is not: hence motion is prior to coming-to-be” (Collected Works, Barnes ed., vol. 1, p. 550, emphasis in original).

“There is no first instant of movement. Movement cannot not have always been” (Aubry, p. 179). She notes that the Metaphysics does not contain the demonstration of this. Aristotle’s actual demonstration of the eternity of movement occurs in book VIII of the Physics, and basically consists in adding an indefinite regress to arguments like those we have just seen.

“Lambda 6 in effect establishes that the principle of such a movement must be not power but act. We have already seen Aristotle’s insistence here on underlining, as in book capital Alpha, the originality of such a thought of the principle. The argument works in a regressive way, establishing successively that the principle of eternal movement cannot be conceived as a power (dunamis), not even as an active or acting power, but must be such that its very substance is act, he ousia energeia. Its stages, let us recall, are the following:”

“–to give an account of movement, it is not sufficient to assert a moving or efficient (kinetikon e poietikon) capacity, if it does not act (me energoun); for it is possible to have a power without acting (endekhetai gar to dunamin ekhon me energein)”

“–nonetheless, even supposing that the principle acts (ei energesei), we cannot give an account of eternal movement if its ousia is dunamis. In effect, if that which has a power has the possibility of not acting, that which is in-potentiality has the possibility of not being (endekhetai gar to dunamei on me einai)”

“–it follows therefore that there is a principle such that its ousia is act, he ousia energeia” (p. 180).

She notes the striking parallelism of Aristotle’s phrases, but also finds a progression between the two formulae, corresponding to a transition between the “kinetic” and “ontological” senses of dynamis that she has often remarked upon.

“As with that from power to in-potentiality, the transition is thus effectuated from action to act: the principle of eternal movement must be conceived not only as an always active and acting power, but as an act. The argument relies only on the ontological sense of [pure] energeia, understood as that mode of being which is subtracted from the possibility of non-being” (p. 181).

“Ultimately we find posed as the condition of eternal movement, a being of which the ousia is energeia. But to say this is also to say, as the two moments of the demonstration underline, that from this substance is excluded every form of power: as much active power as in-potentiality. Thus — and it is again necessary to underline the force, and the paradox, of such a thesis: the very condition of the efficacity of the principle resides in its absence of power. It is not because it is all-powerful or fully active, but indeed because it is fully act that it is maximally efficacious, since it is the principle of eternal movement” (ibid, emphasis in original).

“That the principle (or principles) of eternal movement are act is deduced again from two necessary properties: eternity and immateriality. We verify equally the claim of Lambda 5: act serves to name not only (as Theta 8 established) the mode of being of the necessary and the eternal, but also that of form or the immaterial” (p. 183).

She goes on to contrast this argument with the more limited concerns of Aristotle’s demonstration of the need for an unmoved mover in the Physics.

“Decisive for the demonstration of Lambda 6, the ontological sense is on the other hand absent from that of Physics VIII. The latter utilizes not the schema of finality and the correlation of in-potentiality and act, but that of efficiency and of the correlation of powers…. [T]he text of Physics VIII considers at length the Platonic hypothesis according to which the first principle can be a self-mover. It is concerned to demonstrate that even a self-mover must have a mover and a moved, and finally to establish that at the origin of change there must be an unmoved mover. But the relation of the unmoved mover to that which it moves is thought on the model of efficiency…. The hypothesis, foundational for Lambda 6, of an unactualized power, or a power that is able to not act, is not envisaged. The action of the mover on the moved is described [in Physics VIII] as that of a mechanical force, working by contact with the first moved thing” (ibid).

In Physics VIII, Aristotle even speaks of a temporally infinite power (dynamis apeiros) behind what is commonly translated as “eternal” movement. In Aubry’ s paraphrase, “But an infinite power cannot reside in a finite body, so the first mover must be thought as being indivisible, without parts, and without magnitude” (p. 184).

Physics VIII is after all concerned with the roots of ordinary physical motion, so it is reasonable that it focuses on the “kinetic” sense of dynamis. It does seem that Metaphysics Lambda refers to Physics VIII’s demonstration of the need for an unmoved mover, so it is reasonable to assume that Lambda represents a later development.

It should not be surprising that Lambda, from a different and later point of view, makes new arguments about the first cause that are not in Physics VIII, and corrects some statements of the latter on its nature. Aubry does not comment on this discrepancy, but is content to do her due diligence in pointing it out. We saw earlier, however, that in Physics III Aristotle does also subordinate the kinetic sense of dynamis to what she calls the ontological one of in-potentiality.

Principles of Substance

“Chapter 5 of book Lambda constitutes a veritable pivot, not in the sense that, as the traditional reading would have it, it would bring to a close a hypothetical first part, or a treatise on sensible substances, in order to introduce a second part, or a treatise on separate substance, but because on the contrary it enunciates the principle of their continuity” (Aubry, Dieu san la puissance, 2nd ed., ch. 5, p. 173, my translation throughout).

“It is indeed in Lambda 5 that it is necessary to seek the key to the unity of book Lambda, and thereby of metaphysics, understood, according to the minimal definition suggested by Lambda 1, as a science distinct from both physics and theology; but equally, and this time against the onto-theological understanding of it, as a science that is not scissionable between a science of common being and a science of the first being — or this time between ontology and theology” (pp. 173-174).

“Lambda 5 in effect contains responses to two of the fundamental questions of Lambda 1, that is to say that of the nature of what is separate, and that of the unity of the principles of sensible substance. These responses are made possible by the results, both positive and negative, of the inquiries conducted in Lambda 2 through 4: the extension of dunamis to the eternal sensibles (Lambda 2); the exclusion of separate Forms (Lambda 3); the distinction between principle and element (Lambda 4). And they have one same term in common: that of energeia. Lambda 5 states in effect at the same time that dunamis and energeia are the common principles of all substances by analogy, and that the separate must be conceived as energeia and not as form. Proceeding from this, it remains for the following chapters, Lambda 6 through 10, to elucidate the nature of separate substance understood as ousia energeia, insofar as it at the same time is principle and cause of the other substances, and has a or some principle(s) in common with them — an elucidation which ultimately amounts to a deepening of the notion of the analogy” (p. 174, emphasis in original).

“As was already the case in Lambda 1, separation is here invoked as a criterion of substantiality, or according to the signification established in books Zeta and Eta, which substitutes for the Platonic idea of existence apart from sensibles that of the capacity for independent existence. This criterion allows us to recall the primacy of substance over the other categories, equally posed in Lambda 1, and thereby to affirm that the causes of substance are their causes as well” (ibid).

“For the term cause (aitia), we will proceed to substitute that of principle (arkhe), in order to declare that ‘it is in another manner again that the principles are the same by analogy, that is to say act and in-potentiality'” (ibid).

Aristotle’s four causes — originally introduced in the Physics — are extremely famous. But the above already suggests that in first philosophy, his “two principles” of act and potentiality will ultimately supersede them. In a simple way, act is the end, and that-for-the-sake-of-which; potentiality is the principle of motion. Form and matter provide overlapping specifications from a more static point of view, for which act and potentiality will again tend to be substituted. Such an overlap among the causes should be no surprise, since they are intended as complementary explanations. We have already seen, for example, that Aristotle’s hylomorphism leads him to ultimately assert the identity of an embodied form with its proximate matter. But I’m getting ahead of myself.

She refers to a passage that “in associating the couple of in-potentiality and act with that of matter and form, enunciates not an equivalence, but the rules of a substitution” (p. 175). Aristotle says “In effect, in act are the form, if it is separate, as well as the composite and privation (for example, obscurity or sickness), while the matter is in-potentiality, since it is capable of becoming the two contraries” (ibid). “Act indeed serves here to express form insofar as it is capable by itself, and not only in its articulation to matter, of an independent existence. This is a great novelty in relation to Zeta and Eta, where act served to name the composite as ousia malista [ousia most of all], as alone capable of independent existence, unlike form and matter taken in themselves. Far from being a simple equivalent, act expresses form insofar as it subsists” (pp. 175-176).

This is a somewhat subtle point, but clear enough. Things that are truly equivalent are bidirectionally interchangeable, without qualification. Here she is saying act expresses form only with additional qualification, which does not license a bidirectional substitution. In effect, we have a one-directional arrow between the two terms, rather than a two-directional one.

“In these lines, the notion of act reveals the ontological sense already distinguished in Theta. On the other hand, it does not have the axiological sense with which Theta 8 charged it, in establishing its equivalence with the notions of telos [end] and of ergon [completed work]. As in Theta 9, it applies also to privation, or to the negative contrary by which matter, like form, can be said to be in-potentiality. Applied to privation, the notion of act expresses again, and paradoxically, the mode of being and this non-being. As for the notion of in-potentiality, it expresses the mode of being of matter insofar as it is precisely capable of a double becoming, — toward form, or toward privation” (p. 176).

“To the notions of matter and form, those of in-potentiality and act thus bring an ontological supplement. There is something distinctive in them, allowing them to express beings where the matter and the form are not the same. It is not only a matter of illustrating the notion of analogy, as we did earlier, in pointing out that the relation between distinct matters and forms can be the same, but more of pointing out that the notions of in-potentiality and act apply not only in the context of a single substance, but between distinct substances, and more particularly between substances where one is the cause and the other the effect (we will see later, but Theta 8 has already apprised us that they also indicate, from the one to the other, a specific relation of causality, that is to say final causality)” (ibid, emphasis in original).

“The last lines of Lambda 5 contain a first response to the question of the unification of the principles of substance. Three kinds of unity are successively indicated, which nonetheless are conjoined:”

“–at the outset, a unity of a focal kind, which consists in the primacy of substance over the other categories, which has the effect that the causes of substance are aloso the causes of all otherr things;”

“–then a unity of an analogic kind, which constitutes the principal object of Lambda 4 and 5, and in virtue of which all beings, even if constituted from different elements, nevertheless have the same principles, that is to say matter, form, and the cause of motion;”

“–and finally, a direct or transitive causal unity, in virtue of which all things have for their cause ‘that which is first in entelechy'” (p. 177).

“This enumeration, we can see, mixes transitive principles and immanent principles. If it recalls the categories of matter and form, and not those of dunamis and energeia that the preceding developments have nonetheless substituted for them, it nonetheless makes the notion of entelekheia intervene, and applies it to the first cause. The latter is no longer mentioned only, as was the case at the end of Lambda 4, as ‘that which, as first of all, moves all things’, but as ‘that which is first in entelechy’. Act, designated this time by the term entelekheia and no longer that of energeia, taken indeed in its normative and axiological sense, which is no longer only ontological, appears from this point as the notion adequate to the designation of the first cause. We find thus suggested the possibility of its extension, which the remainder of Lambda accomplishes, from the corruptible and eternal movable substances to the unmoved substance — and, on this basis, of uncovering a principle common not only to the sensible substances as a whole, but to sensible substances and to the separate substance” (ibid, emphasis in original).

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.

Act as Separable

“At this point in Theta 8, we have completed, by the mediation of the terms telos [end] and ergon [completed work], the justification of the equivalence between the superior terms of the analogy, energeia [act], kinesis [motion], and ousia [“substance”], just as we have justified that between the inferior terms, dunamis [power] and hyle [matter]. But in so doing, we have also subsumed one analogical relation under the other, by showing in the correlation dunamis–kinesis a particular case of the correlation hyle–ousia: power serves as a means for matter to attain the form posed as end, and indeed as a means for the coming to be of substance as unity of matter and form, movement itself being able to serve, in the case of transitive activities, as end and as realization of essence. We have thus completed the transition from the kinetic sense to the ontological sense of dunamis and energeia, and at the same time established the priority of the ontological sense over the kinetic sense.”

“The end of Theta 8 nonetheless begins another process: this no longer aims at showing the ontological sense of dunamis and energeia, but at extending their field of application beyond the corruptible sensible substances” (Aubry, Dieu san la puissance, 2nd ed., ch. 4, p. 141, my translation throughout, Becker number citations to the Greek text omitted).

Aristotle regards the stars as eternal (or more precisely, sempiternal) sensible beings, because on a human time scale their motions and other characteristics appear to be unchanging. From this perspective, he understands not only the first cause but all astronomical entities in terms of pure act (energeia), without any admixture of power (dynamis), or of being that is only in-potentiality (dynamei). But these are still sensible beings subject to motion, so they occupy an intermediate place between terrestrial things and the first cause.

This association with eternity and pure act goes along with his view that unlike terrestrial things, the stars move by necessity. Again, for Aristotle this just means always in the same way. Here he does speak of “what cannot not be”, but I think this is only a consequence of his definition of necessity. It is a reflection of the logical truth that if we say something always occurs in a certain way, then we are committed to saying it cannot not occur in that way, simply because “always” implies “never not” — and not anything stronger than that.

Aristotle’s argument, which ultimately aims to draw conclusions about the first cause from an analysis of things closer to us, is made somewhat easier by the existence of this intermediate case of eternal sensible substances in his conceptual schema. But it does not seem to me that any of his arguments about pure act really depends on this common-sense assumption that the stars are eternal.

Even if we have a different conception of astronomical entities, according to which they just exist on a much longer time scale than terrestrial things, the conceptual distinction of a separable pure act remains available to us. (Hegel, for example, develops a version of it that has no connection to astronomy, and instead appeals only to the lasting ethical and cultural achievements of rational beings.) (See also Grammatical Prejudice?.)

“Act can in effect only be attributed to the eternal sensible substances on the condition of being dissociated from dunamis, redefined as the power of contradiction (in the same way, it will only be able to be extended in book Lambda to the simple substance on the condition of the exclusion of movement). But insofar as Theta 6 introduced it as indissociable from its correlation with in-potentiality, it is the very understanding of the notion of act that seems to be called into question: how do we understand energeia without in-potentiality? What kind of act is it that is no longer the unity of matter and form in the end? Can we under these conditions maintain its identity to ousia?”

“These questions will only find a definitive response in book Lambda. Theta 8 is content to begin the process of the extension of energeia: the notion is in effect applied to the eternal sensible substances. For this application allows us to extract yet another sense, and a more fundamental one, of the anteriority of act according to ousia: if act is anterior to in-potentiality according to ousia, this is also because, contrary to in-potentiality, it characterizes such substances. For these are more so substances than the perishable sensible substances” (ibid).

In the analysis of things around us that are in becoming, we see the underlying modalities of in-potentiality and in-act functioning in an interdependent way. But if we look at in-potentiality and in-act just as modalities, only one depends on the other. That is just what the priority of act is intended to convey.

Aubry sees a new distinction introduced here for the first time. Aristotle first explicitly mentions that dynamis may have effects that are not only contrary but contradictory, and at the same time specifies in-potentiality is a mode of being that can be resolved to act in contradictory alternative ways. But it seems to me that this has been implicit from the moment that talk about potentiality for contraries was introduced. And in the bigger picture, Aristotle’s whole insistence on the priority of act over potentiality and the asymmetry in the relation between them seems to have been designed from the start to support considerations of the independence of act from potentiality.

There could be no potentiality without something being in act. But it is very clear that for Aristotle, the relation of potentiality to act is asymmetrical. By contrast, activity and passivity are completely symmetrical, so it is impossible to have the one without the other. But potentiality depends on act, whereas act seems to be the very thing that makes something an ousia malista, or what is most of all a substance. The criterion for this is precisely “separability” or independence relative to other things. Potentiality seems ubiquitous to us because it is a necessary component of all the terrestrial things we are accustomed to, not because act in principle has any dependency on it. Or such seems to be Aristotle’s argument.

Aubry already emphasized in her reading of book Zeta that for Aristotle, what distinguishes ousia malista is its separability, or ability to have being on its own. But Zeta’s discussion focuses on perishable sensible substances, and therefore on applying this kind of separability to concrete composites of form and the familiar kind of (non-celestial) matter. Here for the first time Aristotle explicitly addresses eternal sensible substances.

“The correlation of in-potentiality and act is here broken: act is no longer presented as the end and the principle of dunamis, but as excluding it. Energeia and dunamis name opposed modes of being, where one is proper to the necessary, as that which cannot not be, the other to the contingent, as that which can be or not be. Dissociated from dunamis, energeia remains on the other hand associated with kinesis [motion]: in effect, the eternal sensible substances are in movement. But movement in their case is not the transition from one state of being to another, or from in-potentiality to act: exclusive of in-potentiality, it is confounded with their very act — by which we indeed verify that for certain beings kinesis can serve as telos [end] and as manifestation of being. Finally, dissociated from in-potentiality, this movement remains no less associated with matter, or at least a certain kind of matter” (pp. 142-143).

“[E]ven though the correlation of in-potentiality to act has been broken among the eternal sensible substances, it operates again between these and the corruptible sensible substances” (pp. 143-144).

“[A]ct can be not only another name for the ousia composed of matter and form (or for matter as realized in a form, the form in a matter), but for ousia as such. Act thus comes to name a superior degree of being, which, insofar as it is exempt from in-potentiality, is characterized by necessity, understood as the impossibility of not being” (p. 144).

“In-potentiality, as being able to be or not be, names an inferior degree of being, which characterizes contingency, but remains no less correlated to act in a relation of dependency that also marks act’s anteriority according to ousia” (ibid).

Aristotle’s text does clearly suggest that astronomical entities are somehow superior to terrestrial things, and it relates this superiority to the notion that they are purely in-act. But a modern understanding of astronomical entities expressed in Aristotelian terms would be that contrary to what Aristotle thought, they are not in fact purely in-act.

There is, however, an alternate basis for vindicating the “superiority” of the celestial over the terrestrial. The cosmos is inconceivably more vast than the earth, and for modern science too causally subsumes and includes it, analogous to the way that Aristotle thought it did.

Since childhood I have felt a fascination for the vastness of space and time, that could include distant galaxies and dinosaurs. Completely unlike Pascal’s famous terror at being so small in this vastness, I experienced this with only the profound wonder that Aristotle identifies as the beginning of philosophy.

Even if we do not regard astronomical entities as eternal sensible substances, I think Aristotle for his part would have no trouble endorsing Kant’s expression of the two great wonders, “the starry heavens above and the moral law within”.

Next in this series: Book Theta: Summing Up

Act in Process

At this point we are starting to sum up the results of Aristotle’s Metaphysics book Theta on potentiality and act. Aubry now makes a stronger statement that what it is in itself to be something in potentiality or in act can only be made clear by considering the relation between the two.

“In fact, and always in continuity with the analogy of Theta 6 [between various particular cases of something being in-potentiality and in-act], we begin by considering the relation of dunamis and energeia — that which, according to Theta 6, is the unique means of understanding these notions in themselves, but which also serves to justify the various equivalences posed by the analogy” (Aubry, Dieu san la puissance, 2nd ed., ch. 4, p. 135, my translation throughout, Becker number citations to the Greek text omitted).

“This relation is defined according to a triple anteriority: energeia is anterior to dunamis at once according to the formula, logoi; according to the substance, ousiai; and, but only from one point of view, according to time” (ibid).

“Of an individual in-act, one must say in effect that she is engendered from in-potentiality by another individual in act…. In-potentiality is no longer presented here as a principle of movement, but as a transitory state between two acts. And energeia in its turn is no longer identified with movement, but with the state of that which moves [something else], insofar as it is identical in form with the moved” (p. 136, emphasis in original).

This case applies to biological reproduction.

“Anteriority according to the formula is qualified as evident: it is in relation to act that one defines in-potentiality” (ibid).

“From [Becker index] 1050a4 on, we go on to explore the third relation of anteriority, that according to ousia [“substance”; what it was to have been a thing]. Here we are at the heart of Theta 8, and indeed of Theta in its entirety, since here the triple transition will be accomplished — from the kinetic sense to the ontological sense; from the model of the transitivity and the correlation of powers to the model of the dunamis–energeia correlation insofar as it applies to transitive change as well as to immanent change; and finally, from the model of efficiency to the teleological model.”

“The anteriority according to ousia is not initially given as an anteriority in the order of existence, but as an anteriority in that of form and of essence…. That which is anterior according to ousia is posterior according to generation: the adult is posterior to the infant…, even though in the latter is found the form that is not fully present. But this inversion from one order to the other is explained by the fact that the anteriority of act according to ousia is that of form as end: the act [the adult] is ‘that for the sake of which’ for generation.”

“Here we rejoin the analyses of books Zeta and Eta, where the substitution of the notion of act for that of form proceeds from the adoption of an etiological, and not only logical, point of view, by which the form is considered in its causal function, and envisaged as end” (ibid).

In a composite of form and matter, the form that is considered as end and not only “logically” will be in a sense identified with the composite as a whole, i.e., with the form as realized in matter.

“The anteriority of act according to ousia is that of the end, that is to say of the form as the term of a process that realized it in a matter — and indeed, in the composite that book Zeta qualifies as ousia malista [ousia most of all].”

“For it is this anteriority of act as end that provides the key to the necessary correlation of dunamis and energeia. One does not say only that energeia is to dunamis as that which builds is to the art of building, or as that which sees is to that which is given to view, but that it is for building that one understands architecture; for sight that one has sight; for contemplating that one has the power of contemplating. Act, from this point on, does not appear only as that in relation to which one defines power, but as that for which power is” (p. 137, emphasis in original).

She quotes Aristotle, “The act is the end, and it is in view of it that the power is acquired” (p. 137).

“We integrate here the results of Theta 7 for justifying the equivalence between matter and in-potentiality; for what justifies this equivalence is that the matter is teleologically determined by the form…. As at the end of book Eta, act serves here to name the unity realized from the matter and the form” (ibid).

Act serves “as another name for the ousia malista [ousia most of all] of book Zeta” (p. 138). And this is none other than the composite of form and matter.

“The ontological sense of energeia nonetheless is presented as being at the foundation of the kinetic sense; if movement can be called energeia, it is insofar as we take it as an index of being…. From now on, what justifies the equivalence between energeia and kinesis is that movement can also be telos. And if energeia and kinesis can be called entelekheia, it is not only in the sense where they name effective and complete being in opposition to the incomplete being that in-potentiality says, but because they name that being which, for in-potentiality, is its end” (ibid).

She quotes Aristotle, “For the ergon [completed work] is the end, and energeia is ergon. This is why the term energeia is derived from that of ergon, and tends toward entelekheia” (p. 139).

She continues, “Ergon thus intervenes as the mediation between energeia and telos, and indeed also between energeia and entelekheia. It was present, we saw, from the first lines of Theta 1, presented alongside dunamis and energeia as a sense of being. We find it also, in a sense at the same time normative and teleological, in the Protrepicus. The term serves here to allow the kinetic sense and the ontological sense of energeia to be unified, and at the same time to range the first under the second.”

“If it can play this role, it is thanks to the double sense that it carries: in fact, ergon signifies at the same time the proper function, understood as the act in which the essence is accomplished, and the oeuvre [completed work]. For the remainder of the text goes on precisely to distinguish between two kinds of act: one intransitive, in which nothing else is accomplished but itself, and the other transitive, which produces a being exterior to itself. To illustrate the first, one gives the example of vision, which is the ergon-function of sight, and serves in itself as a telos, an end; for the second, the example of the construction which, resulting in an ergon-work, the house, is only fully [an end] when taken together with the latter. From this we understand that movement can be called energeia: because it indeed has an ergon and a telos, which are not confused with it, but are its work, or that which it produces, and in which, thenceforward, we can say that it is.”

“In fact, ‘the action of building a house resides in the house that is built, and it comes to be and is at the same time as the house’. This affirmation can appear problematic at first glance: one tends spontaneously to distinguish the transitive activity from what it produces, and the being of the house from that of the movement of its construction, since the house only fully is when, precisely, the movement is no longer. We can nonetheless understand this in the light of the analysis of movement in Physics III, and of its characterization as the act common to the mover and the moved: Aristotle already affirmed that the ergon and the telos of the agent and the patient, or of the mover and the moved, reside in one sole and same energeia. In the same way, it seems that the phrase of Theta 8 has no sense unless by the house we understand not the completed house, but the house as object of the movement of construction. We thus understand that the act of construction comes to be at the same time as the house in the process of being constructed, since the two movements (construction/being constructed) are one. The work and the end of transitive activity do not reside in the achieved product, but in the production itself…. The distinction between immanent activity and transitive activity is no longer so great” (pp. 139-140, emphasis in original).

A being that is “in process” can also be an “achieved” being, in varying degrees insofar it also represents an incremental achievement.

“We have seen in effect that act was identical to form as the end and term of in-potentiality, indeed to the form as realized in a matter. If act is anterior to power from the point of view of ousia, this anteriority is not only the logical one of the form-essence and the ousia prote, but also that of substance and ousia malista” (pp. 140-141).

Here we see Aristotle’s strong vindication of immanence and concrete being. Ends — and indeed “perfection” according to a particular kind — are intended to be understood as realizable in form and matter. This is far indeed from the perspective that all finite things necessarily fall infinitely short of a perfection conceived as infinite. For Aristotle, the highest being will be characterized not as infinite, but as pure act and as the good.

Interim Recap

We are still slowly walking through Gwenaëlle Aubry’s groundbreaking fresh reading of Aristotle’s Metaphysics in the second edition of her Dieu sans la puissance (2020). She highlights neglected aspects of the rich meaning of Aristotle’s key terms dynamis and energeia, which I learned in the Latin-based English of potentiality and actuality.

On the one hand, these are central to Aristotle’s account of motion. Aristotle identifies dynamis as the immanent source or principle of motion in natural things. He calls motion itself an incomplete energeia, and the entelechy of a dynamis. But in so doing, he also gives these terms a modal sense that he indicates is more primary than the sense having to do with motion.

That is to say, the Physics already effectively identifies in-act and in-potentiality as modalities of saying something “is” something. To be something in-act is to fully — immanently and concretely, as expressed in actions and interactive behavior — be that thing.

The Physics and other works on nature also already subordinate motion and sources of motion to causality by ends. Aristotle’s general approach to explanation leaves room for mechanical explanation (relativized to the level of hypothetical necessity), but avoids determinism, by subordinating mechanical explanation to explanation in terms of the realization of ends, which may occur in more than one way. For example, an animal is generally determined by a need for food, but the specific ways it will seek or find it on a given day are largely governed by “accidental” conjunctions of circumstances. Hypothetical necessity allows for a kind of play or maneuvering room in the working out of results.

Most recently, we saw that dynamis for Aristotle is always relative to something. Being something in potentiality derives its meaning from what it is to be that something in act. This reflects the priority of actuality that Aristotle always insists upon. If in the register of doing we call dynamis a power, this must be understood in a narrow sense as the power to do something definite. In the case of a “rational” power (one associated with a being capable of deliberation), it is understood as the ability to optionally do or not do some definite thing. More fundamentally, every particular potentiality is a potentiality to be some definite thing, or to exercise some definite way of being.

Since the same being may have many such powers or capabilities, potentiality as a modality is effectively multiple. We never have just one potentiality, but rather a field of potentiality consisting of multiple alternative real possibilities and capabilities.

The relativity of dynamis says that there is never a blank slate, or a completely undetermined situation. Things are not rigidly predetermined, but nothing ever just happens in a completely arbitrary way either. Looking backward, there is always an immanent explanation and a reason why things turned out the way they did.

Critique of the Megarians

Euclid of Megara (not to be confused with the geometer) was a student of Socrates who combined Socratic and Eleatic ideas. He reportedly claimed that virtue is knowledge of the Parmenidean One Being, which he also identified with the Good, God, reason, and mind. At a time when Megarians were banned from Athens for some reason, he is said to have entered the city disguised as a woman in order to listen to Socrates. He was present at Socrates’ death, and afterwards offered refuge to Plato and others in Megara. Socrates reputedly rebuked him for arguing more for the sake of winning than for the truth, but Euclid was said to have been very concerned with moral virtue. Plato credits him with having written down an actual conversation between Socrates and Theaetetus, which became the basis of Plato’s dialogue Theaetetus.

Euclid’s students were mainly interested in logic and argument. Some of them apparently founded a separate school, known as the Dialecticians, which developed a form of propositional logic. This latter group is considered to have been the major source for Stoic logic.

In chapter 3 of book Theta of the Metaphysics, Aristotle criticizes Megarian arguments that there is no distinction between power and act. Aubry quotes Aristotle’s restatement of the Megarian claim, “It is when a thing acts that it can act, but when it does not act, it cannot act” (Dieu san la puissance, 2nd ed., ch. 4, p. 122, my translation throughout).

Independent of Aristotle’s development of a normative and teleological dimension of act that plausibly extends even to physical motion, he is also very concerned to carefully distinguish between power and its exercise. Thus he had to confront the Megarians, who argued that there is no such distinction.

Later writers of quite varying persuasions have wittingly or unwittingly developed variants of this Megarian position. Nietzsche, for instance, explicitly denied the reality of anything that is not actual. Any kind of argument for complete determinism has a similar effect, as does theological occasionalism, which subsumes all becoming under the model of creation.

“Against this thesis, it is necessary to affirm not only the distinction of act and power but, more precisely, that with a given act can coexist not only the power of which it is the effect, but the power for another, opposed, act” (ibid).

Aubry noted a bit earlier that the emphasis on contraries in the discussion of rational powers is rather accidental. The more general point — expressed at the level of potentiality rather than power — is that potentiality includes multiple alternate possibilities concretely grounded in the same state of actuality. The more specific notion of contrariety only comes into play because — due to the fact power is consistently understood by Aristotle as power to do or undergo something definite — related deliberation may be conceived as about exercising a power or not.

She quotes Aristotle, “It is possible for a thing to be capable of being and nonetheless not be, or capable of not being and nonetheless be” (ibid).

This, it seems to me, is an unavoidable presupposition of any coherent account of becoming. It is again also the foundation of Aristotle’s account of human freedom. This way of approaching freedom is greatly to be recommended, because it avoids both the dubious and dangerous concept of a separate faculty of will distinct from reason, and the worse concepts of arbitrary will, or will as “superior” to reason.

“The critique of the Megarians indeed carries a double, and paradoxical, positivity: it invites us to think at the same time becoming in relation with dunamis, and energeia in relation with being. In doing this, it indicates also the double stakes of the inquiry: to think becoming and being at the same time; to determine the mode of their articulation.”

The dynamis–energeia pair is what uniquely enables Aristotle to think of being and becoming in a non-opposed way, though this is far from exhausting its significance.

“The extension from the kinetic sense of energeia to the ontological sense is presented as a deepening: otherwise said, and in conformity to what Theta 1 noted already, it is the ontological sense that is primary. In effect, if we have a tendency to consider that energeia is manifested above all in movement, this is insofar as we take it as an index of being” (p. 123, emphasis in original).

“For not to be in act but to be capable of being so, is also a mode of being: that which in-potentiality names. Of certain things that are not, but are nonetheless capable of being, one says thus that they are dunamei” (pp. 123-124).

Here we have a good example of the explicitly dative grammatical form of dynamis (dynamei) that she finds to be associated with Aristotle’s distinctive notion of being in potentiality. These are things that have being potentially, or are potentially thus-and-such. Here the emphasis is all on “things” in a state of potentiality, or potential “states of affairs”. Potentiality (as distinct from actuality) is the modality in which these have being and are said. This is indeed clearly different from a power to do, cause, or undergo.

“That which is in-potentiality, nonetheless, is not, ‘because it is not an entelechy‘” (p. 124).

We do not say of that which is in-potentiality that it “is” simply, or in an unqualified sense.

At the link above, I suggested that entelechy is probably the most important guiding concept of the Metaphysics. I have also suggested that entelechy serves as a kind of explanation for how ousia or (substance or essence, or what Sachs calls “thinghood”) works. In turn, Aristotle uses ousia to help disambiguate and organize what is meant by the various ways in which we say something is something. In the quote above, he directly uses entelechy as the criterion for what we do and do not say “is”. It is vitally important that he appeals to this much more nuanced concept, instead of referring back to the blunt instrument of a common-sense notion of existence or reality. For Aristotle, being, existence, or reality is not an explainer; instead, it needs to be explained.

Nonetheless, Aubry points out that here, Aristotle does not explicitly invoke the normative aspect of entelechy. We are still primarily investigating the more common “kinetic” sense of dynamis and energeia that accounts for physical motion. The aspect of entelechy that is to the fore is therefore that of the continuing activity that constitutes a substance as something persisting, or a motion as ongoing.

Reading Metaphysics Theta

This will be the first of several posts on Gwenaëlle Aubry’s detailed analysis of book Theta of Aristotle’s Metaphysics. Here I will cover her introductory remarks.

In Aristotle’s text, “the ontological sense of dunamis and energeia, which the use of the dative expression to dunamei kai energeiai indicates, will not be explored at the outset. We depart from the kinetic sense of these notions, designated as corresponding to their current usage, but not from the project of the inquiry. And it is only later that we will see how dunamis and energeia exceed what is said solely in relation to movement” (Dieu san la puissance, 2nd ed., ch. 4, pp. 117-118, my translation throughout).

“This extension, nonetheless, is also a deepening: the ontological sense will be progressively extracted from the kinetic sense, and the sense ‘sought’ from the current sense, but as that which the latter presupposes. For the notions of entelekheia [entelechy] and of ergon [a work] which the beginning of Theta highlights play a fundamental role in the transition from the kinetic sense to the ontological sense of energeia: it is they that mediate between energeia as the name of movement and energeia as a sense of being. And again, they allow it to be understood that energeia says being: not only subsistence or presence, but the function in which is accomplished the form or essence (en-ergon), and in this also the end (en-telos). Energeia is thus found coordinated with dunamis not only as the effective to the possible, but as the end toward which it tends” (p. 118).

“[T]he transition from the kinetic sense to the ontological sense goes hand in hand with a transfer from the model of efficiency and of the correlation of powers to that of finality and the actualization. of the in-potential. This last model, as we have seen, is already at work in the physical and biological writings, but Theta gives it an ontological foundation” (ibid).

Where I see Aristotle’s teleological and normative explanation of being as an alternative to impoverished articulations of first philosophy as “ontology” (i.e., a pure concern with being as existence, subsistence, or presence), Aubry instead chooses to retain the term “ontology”, while transforming it into a teleological and normative account. What she calls the ontological sense of the terms is for me their teleological sense.

“We must begin by studying the kinetic sense (or the sense that is at the same time kurios, first from the point of view of current usage, and me khresimotatos, not the most useful, not the one we seek)” (ibid).

This kind of approach, which takes ordinary language and what is commonly accepted as starting point but eventually moves beyond them, is very typical of Aristotle.

“This usual sense of dunamis is that which book Delta [on things said in many ways] already explored, but nonetheless did not consider in its correlation with energeia. If Theta resumes the first definition and the different senses distinguished by Delta, it nonetheless orders them and operates a sorting among them: thus dunamis is initially designated as equivocal, but among its significations, certain are designated as purely homonymic…. By contrast, the other senses of dunamis can all be referred to a primary sense: that of a ‘principle of change in another thing or in itself as another’. This primary sense of dunamis is indeed an active sense. Nonetheless, the definition proposed in Theta does not manifest this as such, since it does not indicate whether the change in question is enacted or undergone” (pp. 118-119).

“Thus in Delta as in Theta, the distinction between active power and passive power is effaced before the univoval characterization of dunamis as arkhe, as principle of change: or better, the distinction of active and passive is offered as a trait of change more than of the power that presides over it” (p. 119).

Arkhe, which Aubry here renders by the French cognate of “principle”, is what Sachs in his translations calls “source”. Dynamis at the “kinetic” level is a source or principle of motion and change, which renders Aristotle’s phrase for what got Latinized as the efficient cause.

I’m beginning to appreciate that Aubry is far from claiming that dynamis never means power in Aristotle. When I recently began studying this work more closely, I was initially confused to see her frequent use of the French puissance, as opposed to her emphatically preferred en-puissance. (I think at least once in an earlier post I substituted English “potentiality” — which I’ve been using for en-puissance — for what should have been “power” (for puissance) in my translation. Regardless of the grammatical form in the the Greek, Sachs and other English translators choose one word — “potency” for Sachs, “potentiality” in older translations influenced by the Latin. This makes the distinction Aubry is focusing on invisible.)

As things are coming more sharply into focus with this closer reading of her work on Aristotle, I now think these uses of puissance are her reflection of the nominative form used by Aristotle himself in many passages. As she says, the nominative form could denote an active power, but the dative form rules that out. According to Aubry, what she calls the ontological as opposed to the kinetic sense — the distinctively Aristotelian being-in-potentiality, as contrasted with the more generally recognized power to move things — is mainly associated with the dative. But the nominative nonetheless plays quite a large role in Aristotle’s text. And it is quite appropriate for the kinetic sense of dynamis, the one associated with motion and largely anticipated by Plato. But she has first emphasized the symmetry and reversibility of active and passive dynamis, and now suggested that dynamis is in a way indifferent to the distinction of active and passive.

She quotes Aristotle, “It is indeed evident that in a sense the power of acting and the power of undergoing are one” (p. 120).

“Principle of movement, dunamis can also be resistance to a movement of deterioration or of destruction: it is as such a state of impassibility, a hexis apatheias…. It is necessary to note that on the other hand, the capacity of resistance to a movement toward the better is not qualified as dunamis…. One notes already the gradation between a neutral sense and a normative sense that the notion of energeia will engage” (ibid).

“Dunamis, whether it be active or passive, is always found associated with a positivity and a possession (hexis). It is its contrary, impotency (adunamia) and the impotent (adunaton) that one associates with privation, steresis” (ibid).

“[P]ower, whether active or passive, remains univocally characterized as a principle of movement, and as being of the order of possession and of positivity” (p. 121, emphasis in original).

Potentiality for Interaction

“Before being elucidated in Metaphysics Theta as a sense of being, dunamis appears in the physical texts as the instrument of the thought of change and action. It is thus thought in the order of the correlation not of the in-potentiality to act, but of active power to passive power. The model is the mechanistic one of efficiency. This model is nonetheless subsumed under another, which for the correlation active dunamis / passive dunamis, substitutes that of dunamis to energeia, thus integrating the schema of efficiency under that of finality. The definition of movement and its characterization as the common act of the mover and the moved appears as an essential moment of this integration: it invites us to see in kinesis [motion] not only the result of the interplay between two powers, one active and the other passive, but the transition between two states of being. Interaction thus appears only as the means for actualization, the play of powers as the occasion of the realization of the in-potentiality” (Aubry, Dieu san la puissance, 2nd ed., ch. 4, p. 103, my translation throughout).

This all seems very sound. I would add only two more nuances. First, not only is so-called efficient causality or Aristotle’s notion of “sources of motion” subsumed by final causality, but it also subsumes mechanistic “action” under a broader notion of “means”, as in the example from the Physics in which the art of building is what is most properly said to be the source of the motion of building a house. Aubry herself also speaks of interaction as a “means for actualization”.

Second, she speaks here of interaction because Aristotle analyzes even the most unilateral, mechanistic physical “action” as a special kind of interaction between active and passive powers. Although Aristotle would also agree with Kant against Leibniz that there is real interaction between things, that is not at stake in the contrast here. For Aristotle, all action is really a kind of interaction in the special sense mentioned above, but I think what he means primarily to contrast with actualization is action as such, not interaction as such. I would thus suggest the friendly amendment “action appears only as the means for actualization”. On the other hand though, she is emphasizing the fact that all action for Aristotle is really interaction, which is also extremely important.

In On Generation and Corruption book I, Aristotle describes cyclical transformations of the four elements. Aubry notes that the elements are there said to have neither forms of their own nor any principle of autonomous movement. The reciprocal action of the elements is explained in terms of active and passive dunamis.

“[A]ction has for effect an assimilation of the patient to the agent; but always in the case of a material agent, it can entail a passion in return…. If dunamis determines the agent as well as the patient, it is indeed according to a reversible schema, and in a relation of co-implication” (p. 104).

“This first formula, which accounts for action by the correlation of an active dunamis and a passive dunamis, is nonetheless succeeded by another, which substitutes for the pair of powers that of in-potentiality and of act” (ibid).

“The agent is no longer solely determined as active, but as in act…. As for the patient, it is not only passive, but in-potentiality. If there can be action of the one on the other, it is because the effect is already present, dunamei [in potentiality], in the patient: fire, for example, can only heat that which is already hot-in-potentiality” (ibid).

She quotes from book II: “That which is hot in-act is cold in-potentiality, and that which is cold in-act is hot in-potentiality, so that, at least if they don’t equalize themselves, they transform themselves the one into the other” (p. 105).

She continues, summarizing “This cycle obeys the principle of the best, and has a finality of its own” (ibid).

“All the same, the elements are deprived as much of active power as of spontaneity. Their movement toward a place should not be understood on the model of action, or of the interaction of an active power and a passive power, but on that of actualization, and of the correlation of the in-potentiality and the in-act” (ibid).

“The case of elemental change indeed appears as an example of the substitution of the model of actualization for that of interaction, and of the model of finality for that of efficiency. Aristotle starts from the place where mechanistic explanation seems the most justified: the first elements, the original impulses of matter. But precisely, these are not, like the dunameis that fill the khora [receptacle] of [Plato’s] Timaeus, brute and disordered forces: they are passive powers, deprived of self-motion and of spontaneity, but which nonetheless are principles of movement, and have an orientation or a tendency. Between them and their act, the active power, efficiency, only intervenes as an exterior cause; it is nothing more than the occasion for their actualization” (p.106).

Far from serving as the primary model for causality in general, efficient causality in Aristotle only provides occasions for more essential causes or reasons why to operate. It is always only a means for something, a kind of circumstantial catalyst.

On the Soul book II distinguishes “two degrees of dunamis. The first, according to ‘the genus and the matter’ is a non-exercised native capacity — that in virtue of which every human is capable, simply insofar as she is human and possessed of reason, of understanding grammar; the second is a capacity already employed, exercised, the effectuation of which requires no supplementary apprenticeship, but simply the will and the absence of obstacles…; and finally entelechy, or the actual exercise of knowledge” (p. 107).

“The case of perception, like that of elemental change, must be conceived as a transition from second dunamis to entelechy. This kind of alteration (alliosis) neither affects nor destroys the nature of the subject, but on the contrary is ‘a progress toward itself and toward entelechy'” (pp. 107-108).

“Nonetheless, in the case of the apprenticeship of knowledge, the passage from first dunamis to second dunamis should also be conceived as alteration-amelioration…. More than on the distinction between two degrees of dunamis and between movement (kinesis) and change (metabole), it seems it is necessary to insist on that between two types of alteration, the one privative and the other positive. This distinction underlines once again that the intervention of the efficient cause and of the external agent can serve as the occasion of an immanent progress” (pp. 108-109).

“In the transition between the model of interaction and the model of actualization, the definition of motion as the common act of the mover and the moved also appears as an essential moment” (p. 109).

“In Physics III, movement is defined as the entelechy of that which is in-potentiality as such…. Movement, otherwise said, is the act of the dunamis of a being not as such, but as mobile: the process of fabricating a statue is not the act of the brass as brass, but of the brass insofar as it becomes a statue. Immediately proposed, this definition is designed as a sort of default; of movement, in effect, one can say neither that it is privation, nor power, nor act; it is necessary, ultimately, as difficult as this may seem, to define it as an incomplete act, energeia ateles, in opposition to a simple act, energeia haple” (ibid).

“Movement indeed manifests the power of a being whatever it is, that is, independent of what it is, [independent] as well as of that by which such a being can become other than it is…. Movement is indeed the the entelechy of a power as such, since being a power is being a principle of movement, but the power is always the power of a being that by that movement becomes what it is. As consequence, the distinction is not between two powers, but between becoming as the being of power, and the being in view of which there is becoming” (p. 110).

“If the analysis of movement makes appeal to the distinction between mover and movable, and indeed between agent and patient, this distinction nonetheless finds itself relativized: in fact… the mover moves in being itself moved — since there exists also, Aristotle points out, an unmoved mover. The agent indeed is at the same time patient, and the patient in its turn can become agent, so that everything is both agent and patient, poietikon kai pathetikon. But to this it must be added that act is the same in the agent and the patient” (ibid).

“The duality of agent and patient, or of mover and moved, is reabsorbed thus, according to the point of view specified, into that of in-potentiality and in-act. In-potentiality, to dunamei, recovers active power and passive power equally well: it is a point of view taken on both powers insofar as they in principle belong to one and the same movement, or again, insofar as they are the subject of one and the same accomplishment” (p. 111).

Nothing in the real world is ever purely active or purely passive. It is hard to overstate the significance of this.

“In the same way that book III of the Physics subsumes the correlation of powers under movement as the act of the in-potential, book Theta of the Metaphysics places movement under energeia, understood this time not as ateles [incomplete], but as identical to the telos [end]” (ibid).
