The Universe

“From the first lines of Lambda 10, the question of the good and of its relations with the universe is explicitly posed: should the good and the best (to agathon kai to ariston) be conceived as something separate (kekhorismenon), existing in itself and by itself, or as the very order (taxin) of the whole?” (Aubry, Dieu san la puissance, 2nd ed., ch. 5, p. 200, my translation throughout).

“We know from now on that there exists a separate substance, that it is act and not form, that it is identical to the good, and that it acts as an end: from this, it is already apparent that the universe can be neither totalized via its reduction to a unique material principle, as the [Ionian] holists maintain, nor conceived [in the manner of the Platonists] in an episodic manner as a disjunctive series…. The universe indeed constitutes a totality, but this is not exclusive of an order that admits of degrees…. It remains to know whether the good is to be identified with this taxis or is separate from it” (pp. 200-201).

“But these options are not exclusive: the good can be conceived at once (amphoteros) as the very order of the universe and as separate from it, in the way that the good of an army resides in its order as well as in its strategy. It is nonetheless necessary to recognize between these two modes of the existence of the good a relation of anteriority, such that the order depends on the strategy, and not the strategy on the order” (p. 201).

“The problem is thus posed to know in what such an order consists, which is at the same time determined by the principle and serves as its manifestation. Already applied in Lambda 8 to the hierarchy of the spheres and their movers, the term taxis is from now on applied not only to the eternal sensible substances, but also to the perishable sensible substances (animals, plants)” (ibid).

“This order receives a triple characterization: first, it operates in a horizontal way between the different substances…; all these are then ordered in relation to something unique…; but finally, they are not so related in the same way…. We have indeed a relation at the same time univocal and diversified…. It tends nonetheless toward one same end, and proceeds from one same principle” (ibid).

“But we discover now that it is just insofar as [the unmoved substance] is separated that it is the principle of the order and of the distinctive movements of sensible substances…. And we can think the principle or the Good at once as separate and as constituting a taxis, an ordered and related totality” (pp. 202-203).

The universe is held together by the good or the ideal — a principle separate in both the Aristotelian and the Platonic sense, but acting only as a final cause or object of desire — and by the desires and aims of all beings — which in themselves indirectly also aim at the ideal. But nothing “enforces” the good or the ideal at a cosmic level. As a consequence, no evil in the world is cause for doubting the reality of ultimate good.

This concludes my direct treatment of Gwenaëlle Aubry’s detailed analysis of Aristotle in her second edition. When I first encountered her work, I was delighted to see someone vigorously arguing that the first cause is indeed just a final cause, and putting major emphasis on potentiality and act. In the course of working through this, I have improved my own understanding of numerous details. Her book has another 100 pages on what happens to all these issues in Plotinus, which I will pass over for now.

The Ideal

“The last two chapters of book Lambda adopt a new point of view toward the divine: the latter is no longer in the first instance considered as energeia [act], but as good” (Aubry, Dieu san la puissance, 2nd ed., ch. 5, p. 197, my translation throughout).

“The question of the good is nonetheless raised in an indirect way in Lambda 9, by means of an inquiry into nous, or intellect. Here again, the text inscribes itself in the continuity of Lambda 7, and in two ways: first, because the intelligible and the good are identified through the mediation of substance and energeia; then also because the god was described there not only as act, but as an activity of thinking, and as being at the same time the thought of the best, and this thought or contemplation was described as the best and most agreeable” (pp. 197-198).

“Lambda 9 precisely poses the question whether the value of thought comes from its object, or from its very exercise. The response to this question is conditioned by a double premise, which directly articulates the two determinations of ousia energeia [substance as act] and of ousia ariste [the best substance, or ideal substance]: noesis or intellection is the best ousia, he ariste ousia; and as such, it cannot be dunamis. It can have no other object than itself, which would determine its activity of thinking and thus be superior to it; and in the same way, if it were dunamis and not energeia, maintaining the continuity of the activity would be hard. Finally, if it thought of an object other than itself, then it could equally well think different objects, not only the good but ‘something taken randomly'” (p. 198).

“As result, the two initial hypotheses must be eliminated: the value of thought cannot be derived from its object (at least, if the latter is exterior to it, and if it depends on it to be in-act). But no more than this can it be derived only from its activity, taken independently of its object: for thought and the activity of thought also pertain to the one who thinks the worst. If the value of thought can be derived neither from an (exterior) object, nor only from thought’s activity, it is then necessary to say that thought has value not due to what it thinks, but because in itself it thinks. Thus the prime mover ‘thinks itself, if it is true that it is the most excellent, and its thinking is thinking of thinking'” (ibid, emphasis added).

Thinking of thinking, or contemplation, can also be characterized as reflection. I would suggest that what more specifically makes thought thinking itself the best substance is its character of pure reflection. I think that intelligence is fundamentally reflective — a matter not of unexplainable direct apprehension, but of the elaboration of mediation, or of repeated refoldings of a self-referential thread. To be reflective for a human is also among other things to be indefinitely inclusive of new perspectives, while aiming to combine them in a unity of apperception. In the case of the first cause, this unity would be under the modality of always-already.

“But this again leaves open two possibilities: once we have excluded that the value of thought comes only from its own activity, or from an exterior object, we can again ask whether it comes from an object that is immanent to it, or from the very immanence of this object; in other words, does thought think itself because it is the best, or is it the best because it thinks itself? This is the sense of the question posed: ‘And again, if thinking and being thought are two different things, in virtue of which of these two terms does the good (to eu) belong to thought?” (pp. 198-199).

“The response consists in showing that in certain cases, which do not only concern the divine intellect, there is an identity between knowledge and its object — thus we respond to the objection… according to which the knowledge of self is only a parergon, a supplement or an accidental effect, of the knowledge of the object. This identity applies in the case of the practical sciences when they treat of an essence considered as independent of matter, and for the theoretical sciences or intellection, [this identity of knowledge and the known] is itself their object. It remains to know whether this object is indivisible or composed. The response proceeds by way of a new comparison, this time between the human intellect and the divine intellect” (p. 199).

“The passage admits an ethical reading: it is a matter of saying that the human intellect, insofar as it is the thought of composed beings (of matter and form, or of in-potentiality and act), does not have an immediate access to the good, to eu, but only attains the best, to ariston, in time, and as a being different from itself, on allo ti” (ibid).

“In effect it inherits from a decisive premise, which is that nous [intellect] is ousia ariste, the best substance. This proposition is supported in Lambda 7 by the identification of the intelligible, the good, and substance…. This premise, like the resurgence of the notions of the good and the best in the last lines of chapter 9, goes in the direction of an objective, and indeed also ethical, or more so axiological, reading of the text. Certainly thought is of nothing but itself; but if it thinks itself, this is because it is identical with the good” (p. 200).

Ideal Life and Ours

We are halfway through Aubry’s discussion of Metaphysics book Lambda, chapter 7. From this point, she says that the text becomes less of an argument, and more rhetorical and descriptive. Aristotle compares the “way of life” (diagoge) of the divine with “ours”. His discussion here largely follows the much more developed one in book X of the Nicomachean Ethics. Toward the end of Aubry’s section, she also critically scrutinizes the more particular basis of claims that the first cause of book Lambda is not only a final cause but also an efficient cause.

(Though it is much longer than this post, for greater insight and a fuller context on Aristotle’s view of this relation between the human and the divine, I would highly recommend reviewing Ethics book X in The Goal of Human Life.)

Now “it is no longer only a question of movable and perishable substances, but more concretely, and for the first time, of the human subject” (Dieu san la puissance, 2nd ed., ch. 5, p. 189, my translation throughout).

“From the outset, the divine diagoge is characterized by comparison with the human condition, as being ‘like the best’ that is given to us, but also by opposition to it, since what is accessible to us ‘for a brief period of time’, mikron khronon, is for god continuously, aei [always]. The same opposition is found below, between the happy state god enjoys always, aei, but we enjoy only sometimes, pote” (ibid).

She quotes Aristotle, “The [divine] act is pleasure” (ibid). Plato in the Philebus suggests that the divine has a neutral state, but for Aristotle “god is the only living thing that at the same time has access to the most pure pleasure and always knows its enjoyment. If the human also has access to the pleasure of contemplation, she does not know it in a continuous enjoyment, for she is composed of two natures such that each for the other is against nature” (p. 190).

If I may be allowed a shallow comparison, this theme of divine pleasure makes me liken the condition of thought thinking itself to that of a blissful Buddha.

“In book VII of the Nicomachean Ethics, the continuity of divine pleasure is referred to the simplicity of the divine nature which, because nothing is mixed with it or hinders it, always exercises the same activity and finds in it a complete pleasure. The text of Lambda itself is content to associate pleasure and energeia. And where one might expect an exploration of the contrast between the transience of human pleasure and the perpetuity of divine pleasure, the next proposition proceeds on the contrary to underline their similarity. More precisely, the fact that the divine act is pleasure is given as the cause (dia touto [through this]) of the fact that for us every act is pleasure, whether it is a matter of walking, of sensation, or of thinking” (ibid, emphasis in original).

“We can see here a first illustration of the mode of action of the unmoved final cause as it has been determined above: we have immanent ends and aim at our own acts; it remains that through the latter, we also aim at the continuity and indeed the pleasure that attach par excellence to the divine act” (ibid).

“The following lines do no more than deploy the identity between act and pleasure, in formulating the conditions that make a certain act (thought or contemplation) pleasant. That the divine act indeed consists in thought is presupposed (or simply induced from the pleasant character of contemplation for us): above, the god has been assimilated to the intelligible, or to the noeton, but not to thought, noesis. For the act of thought to be pleasure, it is necessary that it be in-act, that is to say that intelligence is in effective possession of the intelligible” (pp. 190-191, emphasis in original).

“[T]hought in itself is thought of the best in itself, from which we deduce that the divine theoria [contemplation] is not only more agreeable, ediston, but also the best, ariston” (p. 191).

(Here again we are reminded how extremely different this is from modern notions of thought as “value free”, which seems to assume that all values are prejudices. We do not have to suppress questions of value in order to be fair and objective. Objectivity and fairness in the real world involve openness, but not a completely relativistic free-for-all. Fairness and objectivity are themselves values.)

“After the identity between act and pleasure, we pose that between act and life, zoe. This time, it is nonetheless clear that this identity only applies to one particular act: that of intelligence. It seems on the other hand that it applies to every act of intelligence, whether it be human or divine. Of the divine act, insofar as it is energeia kath autein [act directed toward itself], we say nonetheless that it is not simply life, but ‘the best life, and eternal'” (p. 191).

I was a little surprised that she says only the act of intelligence is to be identified with life. But she does not say that only the act of intelligence presupposes life, but rather that it is the only one to be strictly identified with it. Life for Aristotle is not reducible to some bare fact like a heartbeat; it involves purpose, and the best realization of purposes involves intelligence. That this applies to the human is no surprise. And if we accept that there is meaningful sense to thought eternally thinking itself, it is also no surprise that for Aristotle this would be the best life.

“It appears nonetheless that in the passage, [energeia] no longer designates a way of being but a way of acting: we no longer say that god is in act, but that god has an act. If this distinction between act and activity is at work, the text nonetheless invites us to surpass it: the activity of god in effect comes down to its character of being in-act. Thus, if god’s activity is thought, and self-thinking, this is, as Lambda 9 will make precise, because god is the good; and if the act is continuous, this is because as act without power, god is without movement or change. The notion of life, zoe, intervenes precisely at the junction of the ontological sense and the practical sense of energeia, serving thus to name the activity of that which is act by itself” (ibid, emphasis in original).

“More decisive seems to be the reiterated distinction between the continuous activity of being in-act, and the discontinuous activity of beings mixed from act and in-potentiality. The latter (or, at least, ‘we’) have access to an activity of the same nature as that of the divine: thought, pleasure, and life. What makes the difference between the theos and ‘us’, is indeed not the nature of the activity, but its duration (continuous/discontinuous) and its value (the activity of god is the best, and indeed also the most pleasant” (ibid).

“This characterization initiates the transition from the ontological approach to the prime mover, governed by the notion of energeia, to [Aristotle’s] axiological approach, governed by the notion of the good, which energeia in its most determinate sense nonetheless also includes. Against the Pythagoreans and [Plato’s successor] Speusippus, we thus repeat that the best and the most beautiful are arkhe [principles or sources]” (p. 192).

“From here the question is posed whether dunamis, more than a mode of being, designates here a mode of action: indeed whether the final cause must also be conceived as an efficient cause. The fact is that we have seen that the schema of efficiency, such as it is expounded notably in On Generation and Corruption, presupposes that the agent is in-act. Further, this schema is extended so as to be applicable to impassible and incorruptible realities: in their case, there can be action without reciprocal contact (they touch without being touched, move [other things] without being moved); and insofar as they are without matter, they are not affected by the action they exercise (the medical art heals without being healed)” (p. 193).

“According to this enlarged model, efficiency — and indeed also the dunamis poietike [power to do or make] seems to be compatible with actuality, but also with immobility, immateriality, and impassibility. The question nonetheless remains whether it is also compatible with the final cause” (ibid).

Previously, she pointed out that book VIII of the Physics does once apply the phrase dynamis apeiron [unlimited power] to the prime mover. This is indeed the passage appealed to by those who want to make the prime mover an efficient cause. The basis for this appeal is that Lambda 7 does briefly recall the argument of Physics VIII that the prime mover is without magnitude or parts.

But she has explained that in Physics VIII, what she calls the ontological sense of dynamis is completely missing, and the context is a long polemic against the Platonic notion of self-motion. Along with the fact that any reference to unlimited power is completely absent from the Metaphysics, and that the “unlimited” power of the prime mover in Physics VIII is not said to be unlimited in all respects but only in relation to time, she argues that this in no way intended to undo Aristotle’s many consistent affirmations that the first cause is pure act without power. This seems entirely reasonable to me.

“That the prime mover is a final cause, [the first half of] Lambda 7 has clearly established. To this must be added that the ontological sense of dunamis and energeia mobilized by the argument of Lambda 6 implies not only… that energeia is anterior to dunamis, but that it is anterior as end” (ibid, emphasis in original).

“Otherwise said… the final character of the causality of the prime mover is already posed, even in ontology, via the exploration carried out in Theta 8 of the asymmetrical relation between energeia and dunamis. As a result, the problem is not whether the prime mover is an efficient cause more than a final cause, but whether it can even be an efficient cause at the same time as it is a final cause. For on this point On Generation and Corruption is explicit: ‘to d’ou heneka ou poietikon‘, ‘the final cause is not efficient’. Thus ‘health is not efficient, except in a metaphorical sense’, that is to say in the sense in which, insofar as it is an end, it sets off an action that aims at it, but in which it is not itself the agent (it is not health that cures, but the medicine or the remedy). In the same way, we can say of the end that it moves [other things]; but we must not confuse that which moves [other things], kinoun, with that which does, poiein, or with the efficient cause as principle of movement, arkhe kineseos: if it is true that the efficient is also a mover, it is not true that every mover is efficient” (pp. 193-194, emphasis in original).

For this last, she cites On Generation and Corruption again.

“In the same way that the ontological sense of dunamis is incompatible with the characterization of the prime mover as pure energeia, its kinetic sense is incompatible with its characterization as a final cause” (p. 194).

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).

Physics and Theology

Returning to Gwenaëlle Aubry’s landmark new reading of Aristotle’s Metaphysics, last time I covered her preliminary roadmap of book Lambda, in which Aristotle discusses the first cause and its relation to the world. Here I will focus on her discussion of chapter 1.

As is common in Aristotelian treatises, Lambda begins with a survey of the opinions Aristotle deems most important and relevant in this area — namely the “physical” approach of the Ionian philosophers of nature, and the “logical” one he attributes to the Platonists. Aristotle will borrow from both, and criticize both.

At the same time, Chapter 1 outlines a program of investigation that will be pursued over the course of the book. This consists of four questions:

1) How are cause (aitia), principle (arkhe), and element (stoikheion) distinguished, and how are they related?

2) Are there principles common to both eternal (astronomical) and corruptible (earthly) sensible substances?

3) How are we to understand the meaning of unmoved substance?

4) Are there principles common to unmoved substance and to eternal and corruptible sensible substances?

The Ionians and the Platonists agree, each in their own way, that it is principally of “substance” (ousia) that we investigate the principles and causes, though they interpret substance differently. Aristotle retrospectively interprets both the Ionians and the Platonists as reaching toward his own notion of substance and its role — i.e., as dwelling on questions about what things are, and about why things are the way they are.

It is the “things” in life that are of primary interest, because to a greater or lesser degree they all have persistence, and therefore also have recurring relevance in their own right. Mere transient events only have relevance to meaning and deeper truth insofar as they may be claimed to show something about recurringly relevant things.

Aubry points out that in book Lambda, it will not be a question of demonstrating the primacy of substance and of independent things over those other “things” that are attributed to them. Something like book Gamma’s argument for the methodological priority of inquiry into relatively independent things seems to be presupposed. Nor does Lambda ask what substance is, as book Zeta does. The specifically Aristotelian sense of substance’s defining criterion of “separateness” — embodied in the relative independence of some but not all of what we call “things” in the broadest sense — which was a major result of Zeta, is recalled in the opening lines of the chapter here, and is thus integrated into Lambda’s inquiry from the beginning. But Zeta’s investigations are also deepened here by a new connection with book Epsilon’s emphasis on causes and principles, so that we now also ask, what are the causes and principles of substance? Moreover, questions raised but unanswered at the end of Zeta about unmoved substance will eventually be addressed here.

Aristotle contrasts the Ionian view of the world of becoming as a certain (material) whole with that of the Platonists, who treat it as a pure succession of phenomenal instantiations of immaterial Forms. The Ionians recognize as principles only the elements of bodies, thus putting all intelligibility on the side of matter. The Platonists recognize only immaterial Forms as principles, and hold becoming as such to fundamentally lack intelligibility.

“Going forward, the opposition between holists and episodics does not outline the alternative according to which the arguments of Lambda will be deployed, but rather, conversely, that which it will be necessary to overcome” (Aubry, Dieu san la puissance, 2nd ed., ch. 5, p. 161, my translation throughout).

In a second contrast between the Ionians and the Platonists, the Platonists associate substance exclusively with what is logically universal (katholou; literally “according to the whole”), but the Ionians associate it exclusively with concrete individual things (kath ekasta; literally “according to each”). Aristotle will bridge this gap too, by posing the first cause as not itself a logical universal, but rather as a unique thing, to which all other things universally have a broadly similar constitutive relation.

Finally, Aubry refers to the passage, “And the former kind belongs to the study of nature (since they include motion), but this kind belongs to a different study, if [ei] there is no source [principle] common to them” (Metaphysics, Sachs tr., p. 231). Scholars have debated the significance of Aristotle’s ei here.

“The translation [of the ei] adopted here [and independently by Sachs] results in a hypothetical meaning, ‘if’, but another reading gives it a causal meaning, ‘since’. Such a divergence is far from being minor. The traditional causal reading of the ei in effect founds a scissionist interpretation of metaphysics, which will be divided between the science of sensible substances, or physics, and ‘another science’, having for its object the unique substance that is separate [in the Platonic sense of separation from matter], which going forward will be identified with theology…. As well as a scissionist reading of metaphysics, these lines invite a hybrid reading of Lambda according to which it is necessary to distinguish between a treatise on sensible substances, and a treatise on substance that is separate [again in the Platonic sense]. Such an interpretation amounts to abandoning any project for a general ontology — eventually only leaving place for a unification from above, that is to say by theology, applied to [the emphasis on causes and principles from] book Epsilon chapter 1″ (Aubry, p. 163).

She cites a survey of this issue by David Lefebvre, but does not directly identify sources for the traditional interpretation. Since the dispute is about a detail of the Greek text though, I would presume that these are traditionally minded modern scholars, and not medieval writers.

“On the other hand, the hypothetical reading of ei leaves open the possibility that there exists a common principle [of sensible and Platonically “separate” substance], and, going forward, also a common science of all the substances, sensible and separate. Nonetheless, this hypothetical reading admits in its turn of two distinct interpretations: one could understand that the common science of all the substances is to be identified with physics; or again that it is the alternative ‘physics’/’different science’ that is itself conditioned by the [presumed] eventual absence of common principles, but that under the hypothesis that such principles exist, this partition can be superseded, to the profit of a unique science of substances — a unique science that can be reduced neither to physics nor to theology” (p. 163-164).

The key point that should be emphasized is that Lambda aims to sketch the basis of a unified account of all substance.

I would go somewhat beyond the scope of Aubry’s argument here, to also question the traditional talk about “sciences” in this context. Aristotle himself simply speaks of knowledge (which we could gloss, following the broader of his usages, as an interpretive account grounded in reasoned explanation). This presupposes rather less than either the ideal of foundational demonstrative science bequeathed to later traditions by Alfarabi, or the whole elaborated apparatus of empirical science, with which “science” is identified in most modern contexts.

I also question the identification of Aristotle’s more specific “ousiology” or account of substance with “ontology”, or the alleged science of being. Properly speaking, we owe the latter to successive post-Aristotelian elaborations, principally by Avicenna, Duns Scotus, and Christian Wolff — however often these elaborations get retrospectively read back into the Aristotelian text. Aristotle does indeed refer without prejudice to the question whether knowledge of being “full stop” is possible, but his eventual answer is the more limited one that a general reasoned account of ousia is possible. I think it shows the original naive question about being to have been badly posed. That way of posing it leads to other nonsensical, non-Aristotelian questions that imply category mistakes, like “why is there being?”

Finally, I give more weight to the fact that the term “metaphysics” is never used by Aristotle, and was only first applied to the collection of treatises we know by that name by an editor, long after Aristotle’s death. I prefer Aristotle’s own term “first philosophy”.

But I do very strongly agree with Aubry that book Lambda is intended to develop what could reasonably be called a general ousiology, embracing both sensible and Platonically “separate” substance; and moreover, that this ousiology has a fundamentally axiological or value-oriented character.

Book Lambda: Introduction

“Book Lambda of the Metaphysics responds to the exigencies defined in book capital Alpha: to pose the good as a principle; and to determine its proper mode of causality as being that of a final cause, and not an efficient or formal cause. These two exigencies are resolved in a single proposition: the principle is act, and is without power. Act here receives its full signification: it is act and not form that is the mode of being of separate substance; but act also serves to name the good as a principle” (Gwenaëlle Aubry, Dieu san la puissance, 2nd ed., ch. 5, p. 153, my translation throughout).

We saw last time that pure act (energeia) for Aristotle — unlike any being in subcelestial nature — has the character of unmixed necessity. This is true because pure act is the only thing that fully is what it is. It is the admixture of power (dynamis) and in-potentiality (dynamei) in other things that is the source of their contingency, as not being pure act.

“If the concepts of dunamis and energeia simultaneously unify ousiology and integrate theology into it, they also bear all the singularity of the Aristotelian thought of being, and within it of the first being, insofar as the latter is conceived not as an excess of power, but as the reality of the good” (p. 154).

Ousiology would be an account of ousia, or what we call “substance” from the Latin. Again, the first cause is not first in the sense of time, but first in the sense that all other things depend on it. The whole point of calling it pure act is to separate it from the contingency of the dependent things that have power and potentiality.

The very idea of an “excess of power” is utterly alien to Aristotle. We saw before that he understands power as always being power for something definite. Only those things that also have a dependency on something outside of themselves have this kind of “power” at all, corresponding to an unrealized in-potentiality. This “power” and potentiality are the mark of their contingency, not of implacable might.

It is Plato and Plotinus who on the other hand associate superlative power with the Good or the One. But Aristotle criticizes Plato for failing to explain how the Good acts as a cause. Then Plotinus later attempts to answer Aristotle’s criticism by adapting and dwelling upon the novel theme of the excessive character of the One’s power that first emerges in the Judeo-Christian tradition.

“To read book Lambda in a unitary manner, and to find this unity in ontology, that is to say in the sense of being that dunamis and energeia express, is not at all to deny or to minimize its theological content. It is on the contrary to affirm the unity of metaphysics, against the onto-theological readings that scission it between a science of common being and a science of the first being. It is also to recognize a continuity among the different treatises that have come down to us under the name of the Metaphysics” (p. 156).

“The date of composition of book Lambda is debated by commentators. But it is necessary in any case to distinguish between the historical question of its editorial status and that of its conceptual relation to the other books of the Metaphysics, with regard to the problems to which responds to, displaces, or resolves, the analyses that it deepens” (ibid).

“The problems treated in the central books [Zeta–Eta–Theta], and most especially in book Theta, seem to us to be decisive. In Lambda, the elucidation of [1] the ontological sense of dunamis and energeia that orients Theta in its entirety; [2] the analogical relation between them in Theta 6; and [3] the anteriority of act over in-potentiality subsequently developed in Theta 8, furnish the conceptual basis as much for the analogical unification of the principles of substance, as for the principal position of ousia energeia” (ibid).

“Massively mobilized in Lambda 6 and 7, [the notions of dunamis and energeia] are absent from the introductory chapter that constitutes Lambda 1, as from the analyses of Lambda 3, and little present in Lambda 8 and 10. Nonetheless, the successive and modulated interventions of dunamis–energeia (or — and it is necessary for us to ask ourselves about this variation, of their dative form dunamei–energeia) over the course of Lambda serve each time to respond to the different questions raised in Lambda 1, which serve as the program for the book in its entirety: what is a principle (notably in its difference from an element, stoicheion, or a cause, aitia)? What are the principles common to sensible substances? What is the nature of separate substance (is it a form or not)? Finally, and these two questions are intrinsically linked, in what way is separate substance a cause, and are there principles common to all substances, sensible or separate?” (p. 157).

Here Aubry notes that while still maintaining his own preferred sense of “separate” ousia (separate as subsisting with relative independence with respect to other things) as distinct from that of Plato (separate as independent of matter subject to becoming), Aristotle nonetheless in this part of the text turns to ask questions about substance that is separate in both of these senses.

“Going forward, we will be able to extract a unitary principle for all substances, sensible or separate, that is not reducible to the unity of the material composite; and at the same time to maintain, under the auspices of this unity, a hierarchy that is not episodic or disjunctive” (p. 158).

What makes the hierarchy of substance not episodic or disjunctive in Aristotle is the explanation he provides for the mode of causality of the end and the good as that for the sake of which.

“Lambda 2 will thus substitute the notion of in-potentiality for that of matter, in order to extend it, beyond the corruptible sensible substances, to the eternal sensible substances. This positive result is followed in Lambda 3 by a negative, but decisive, result, since we will establish, against Plato, that form cannot be separate. In Lambda 4, it is this time against its reduction to an element [i.e., a constituent in the material sense] by those who wrote about nature, that the notion of principle will be redefined” (ibid).

For Aristotle, a principle of something is never reducible to a constituent part of it, and what any given thing “is” is always more than a mere sum of its parts.

“The veritable pivot of book Lambda, chapter 5 goes on to integrate these various results, negative as well as positive: the extension of dunamis to the eternal sensibles; the exclusion of form from consideration as the mode of the being of the separate; the distinction between principle and element; and going forward, [chapter 5] brings two fundamental responses to the questions posed in the introductory chapter: separate substance must be conceived as act and not as form; and dunamis and energeia are, by analogy, the principles common to all sensible substances” (ibid).

“On this basis, the central concern of chapters 6-10 will consist in determining and exploring the mode(s) of relation between separate substance and the other substances. Lambda 6 having demonstrated that separate substance as ousia energeia is the condition of the movement of the other substances, it remains to identify its mode of causality as being that of the end (Lambda 7) and of the good (Lambda 9), but also the way in which this causality operates in the case of the eternal sensibles (Lambda 8), and, finally, the whole universe (Lambda 10)” (ibid).

The whole universe coheres intelligibly, both insofar as it realizes the good, and insofar there are also explanations when things fall short or go wrong. The world we live in is not a mere whole made up of discrete parts, as the pre-Socratic writers on nature tended to assume. Neither is it the mere sequence of disconnected episodes that follows from the Platonic sole emphasis on what Aristotle calls formal causes.

Mixing Up Plato and Aristotle

Chapter 3 of Gwenaëlle Aubry’s Dieu sans la puissance analyzes Aristotle’s discussion of ousia (“substance”) in book Zeta of the Metaphysics, and the transition toward potentiality and act in book Eta. The discussion is very dense, and will merit at least one further post. The whole chapter elaborates her argument for an important distinction between form and act. Here I will focus on her introductory remarks.

The key Aristotelian term ousia already had established usages in Plato, some of which conflict with the meanings Aristotle gave to it. According to Aubry, the traditional interpretations that attribute to Aristotle a notion of separate form independent of the composite depend on reading distinctly Platonic (and non-Aristotelian) meanings of ousia into Aristotle’s text. I won’t get to the full justification of this here, but it is coming. The term “separate” is also used differently by Plato and Aristotle. In Plato, it means apart from sensible things, but in Aristotle it means able to subsist independently.

“Contrary to that of potentiality and act, the couple of matter and form is never counted by Aristotle among the senses of being. It nonetheless became one of the fundamental motifs of scholastic Aristotelianism, to the point where the notions of dunamis and energeia are happily identified the one with matter, the other with form. This had the effect, in particular, that one could affirm generally that the unmoved First Mover is a ‘pure form’, even though Aristotle only designated it as act, and never used terms for which the translation could be ‘pure form’. This indistinction of act and form is also at the origin of the affirmation, also very widespread, according to which Aristotle would accept the existence of ‘separate forms'” (2nd ed., p. 67, my translation throughout).

She notes that many esteemed modern commentators, including Werner Jaeger and W. D. Ross, have followed this scholastic interpolation. For the absence in Aristotle of any terms translatable as “pure form”, she cites a 1973 article by E. E. Ryan, “Pure Form in Aristotle”.

“[I]t is hard to see what would lead Aristotle to forge two neologisms [energeia and entelecheia, or act and entelechy] to designate what a concept in the repertoire [eidos, or form] already sufficed to name. But what is more surprising is that in identifying act and form, and attributing to Aristotle the assertion of separate forms, one thereby attributes to him a doctrine he had himself combated in Plato, only in the end to reproach him for finally remaining a Platonist” (p. 68).

Modern criticisms of Aristotle have often targeted his alleged reliance on a notion of pure or separate form.

“The indistinction of form and act appears to us in effect to be at the source of numerous criticisms addressed to the Aristotelian metaphysics: thus one demands to know how it can at the same time admit the existence of separate forms, and affirm that the form is never given without the matter; one asks oneself about the coherence of an ontology having for its object both substances composed of matter and form and pure forms; one deplores the abstract character, the intellectualism, of a theology of pure form. But nevertheless, the reduction of act to form is also the basis of the traditional (‘onto-theological’) reading of the Metaphysics” (ibid).

According to Aubry, there are two principal differences between act and form.

First, “Only act implies subsistence; or again, only act is fully ousia — that which says also ‘separate entelechy’…. Form, on the contrary, is not [simple substance], because it does not exist in a separated state. If it is separable, it is only in a very limited sense, [according to the logos], writes Aristotle, or ‘according to the formula’; in the sense, certainly, where it can be thought and defined without the matter, but not in the sense where it could subsist by itself, independent of any material instantiation” (pp. 68-69).

Again, Aristotelian separateness is not Platonic separation from sensible being, but rather the capacity of a thing to subsist on its own.

Second, “Act nonetheless does not say being solely as separate, capable of subsisting by itself, but also as identical to the end and the good. This axiological significance only appears, before being confirmed in Lambda, in book Theta, at the end of the course by which the notion of act is substituted for that of form” (p. 69).

What she here calls the axiological significance of act — its essential involvement with valuations and ends — stands in contrast to its traditional “onto-theological” interpretation. Also, there now seems to be a question whether some of my own expansive remarks about form should perhaps be applied to act alone.

“[The substitution of act for form] explains the possible confusion between the two notions, but at the same time it indicates the procedure and the conditions which mark well that they are not simple synonyms. The principal operator for these appears to us to be the central notion of books Zeta and Eta and, to a lesser degree, of book Theta: the notion of ousia, as well as that of separation, which is strongly correlated with it. One of the great difficulties of book Zeta comes in effect from a partial conservation of the Platonic sense of the notions of ousia and of separation, which leads to a conservation of the primacy of form. Aristotle nonetheless also elaborates his own concept of ousia, which he associates with separation not in the sense of existence outside of sensibles, but as a capacity for independent existence. Thus redefined, ousia excludes form” (ibid).

That is to say, what Aristotle calls ousia malista [what is substance above all] excludes form. As we will see, she says that ousia in a broader sense subsumes form in the way that energeia and entelecheia subsume form, but this relation is not convertible — ousia, energeia, and entelecheia for Aristotle all cover more cases than eidos [form] does.

“This tension between two senses of ousia is reflected by the distinction, in Zeta, between ousia malista [what is substance above all] and ousia prote [primary substance], and by the correlative promotion of two candidates to the status of ousia: the composite of matter and form, and form. It is the intervention, in book Eta, of the notion of act that allows this tension to be resolved: act in effect satisfies at the same time both the Platonic criteria and the Aristotelian criteria for ousia, making it possible as a result to think both intelligibility and permanence, both essence and substance” (ibid).

“In Plato, the term ousia indifferently designates the reality, the existence, or the essence, the ‘what-it-is’ (the ti esti); it applies equally well to being in opposition to becoming, as to the totality of the real, or inversely to its terms in composition” (p. 70).

“Plato nonetheless also calls intelligible being, the Ideas and the Forms, ousia. Its distinctive characteristics are thus, along with intelligibility, permanence, immutability, eternity. On the other hand, Plato never makes separation, understood in its Aristotelian sense as capacity for independent existence, a distinctive criterion of ousia” (ibid, emphasis in original).

Whether Plato really must be read as asserting that the Forms are separate in an Aristotelian sense is a separate question, but there is no doubt that Aristotle and most others have attributed such a view to him.

For Aristotle, “Platonism consists in distinguishing from the sensible its principle of intelligibility (the universal and the definition), and giving to the latter an autonomous existence” (ibid). But for Aristotle, “That which is, is not walking, or good health, or a seated position, but the thing that walks, has good health, and is seated” (p. 71).

“Nonetheless, like being, primacy is said in many ways” (ibid).

“Among the traits characteristic of ousia, Aristotle preserves, alongside the criterion of separation, those which, in Plato, justify the primacy of form, such as permanence or intelligibility. These allow it to be well said that form is ousia, but in a qualified sense. Book Zeta is thus presented as a combinatory hierarchy of criteria that in turn serves to determine a hierarchization of different beings pretending to the title of ousia, but also a distinction of different degrees of ousia” (p. 72).

“[I]f form cannot be called ousia absolutely, it nonetheless retains a primacy from the point of view of the formula and of knowledge” (p. 73).

“It is precisely this conflict that is resolved in Eta by substitution of the notion of act for that of form…. [Act] thus names the unity of the subsistent or separate individual, … as well as its principle of permanence and intelligibility. Thus only the notion of act satisfies all the criteria of ousia, in that it permits the reconciliation of the Aristotelian requirement of autonomous subsistence and individuality with the Platonic one of permanence and intelligibility” (ibid).

“For the combinatory hierarchy of Zeta is thus substituted an integrative synthesis [in book Eta]” (ibid).

“Considering form as act is in effect considering that in it which acts as an end, that is to say the principle of a becoming at the end of which matter is fully determined by form, and the form realized in a matter” (pp. 73-74).

“[I]f there can be no form without matter, there can on the other hand be an act without potentiality” (p. 74, emphasis added).

In an upcoming post(s), I’ll treat Aubry’s substantiating analysis of books Zeta and Eta.

Distinguishing Act and Form

“In fact, the notions of form (eidos) and of act (energeia or entelecheia) are not equivalent; and if the first belongs to a Platonic vocabulary, the second is an Aristotelian invention. It belongs, as such, to an anti-Platonic project: there is no sense, for Aristotle, in posing ‘pure’ or ‘separated’ forms, that is to say forms subsisting outside of and independent of the composites that they define. Form is not separable except ‘by logos‘, ‘according to the formula’, which signifies also that form is not fully ousia, fully substance” (Gwenaëlle Aubry, Dieu sans la puissance, 2nd ed., part 1, introduction, p. 23, my translation throughout).

For Aristotle, form is only separable from the embodied composite analytically, in speech or in thought. Though he was Plato’s star pupil for 20 years and continued to be influenced by Plato in other ways, his project is “anti-Platonic” in the sense that he specifically criticizes the notion of separate form, with which Plato is famously associated.

“It goes otherwise for act, which implies separation, understood as autonomous subsistence, and therefore has the value of another name for ousia. Act, nonetheless, is not only another name for substance. Identified with the end, it is also [identified] with the good. Being in act is not only to subsist, it is to subsist as adequate to its form and to a form that, posed as end, is also posed as good…. Act thus is not only another name for being, but also for the good: or more, insofar as it says the good as real, or as realized, [it] names the identity of being and the good” (p. 24).

Here it is important to recall once again that all the senses of “being” Aristotle discusses in the Metaphysics involve being as a transitive verb (i.e., being this or that), not being as a noun. Being in the sense of existence simply has no place in this account. The identity of the senses of being as a transitive verb with those of the good tells us that the saying of transitive being for Aristotle has a normative character. Talking about the being or essence of things is talking about value, and making value judgments.

“Certainly, [the idea of] the unmoved First Mover does not come in response to the question of the emergence of being, but to that of the eternity of movement — both the continuity of the movement of the stars, and the perpetuity of the cycle of generation and corruption. This is why [book] Lambda [chapter] 10 [of the Metaphysics] can also designate the good as the cause of taxis [order], associated both with the movement of the eternal sensibles and that of the corruptible sensibles. If it is not an efficient cause, the First Mover nonetheless has an efficacity, or an influence on the world, which follows from the very fact that it has no power. For the purely actual substance, indeed excluding power as much as movement, is required as the condition of movement (Lambda 6 and 7). Again, it is necessary to determine the way in which it is [required]; Lambda 7 invokes the notion of final cause, which it is nonetheless necessary to understand in a particular sense: not in a sense in which the unmoved substance is itself the act and the end of the other substances, but in the sense in which, aiming at their proper act, the latter aim at the same time at its characteristic necessity. To understand this, it is not necessary to have recourse to the notion of imitation: the relation of the pure act to the substances mixed of act and potentiality is determined by the different relations of the anteriority of act to potentiality distinguished in Theta 8.” (p. 25).

Aristotle is saying that the good in general or value in general is a condition for the possibility of all movement, both celestial and terrestrial. Every being is moved by some good or other. Aubry is here explaining the difference between Aristotle’s own view and the “ontotheology” that Heidegger and others have attributed to him.

“[The pure act’s] efficacy could be called non-efficient; its strength merges with the desire it arouses. Designating god as act, Aristotle identifies his mode of being; determining the mode of relation of act to potentiality, he identifies his mode of action….”

“But by this, Aristotle also identifies the mode of being and the mode of action proper to the good. It is perhaps thus that it is necessary to understand his insistence in affirming that he is, of all the philosophers, the first and the only to have posed the good as a principle….”

“The singularity of the Aristotelian theology as a theology of the good, and of the power proper to the good, can nonetheless not be known except on the condition of taking seriously the designation of the First Mover as pure act. This supposes in particular that the Aristotelian inventions that are act and potentiality are not reduced to form and power. The Aristotelian theology, that is to say the science of unmoving and separate substance, appears only in effect as one of the areas of application of an ontology or, at least, a general ousiology, which has for its foundation the notions of act and potentiality” (p. 26).

In contrast to the ways being is said in the senses of the Categories, which are “inadequate for speaking about the first unmoving being, [act and potentiality] allow both the difference and the relation of moved and unmoved substances to be thought. In a more general way, act and potentiality are at the foundation of an anti-Parmenidean ontology, …allowing being, movement, and their correlation equally well to be thought” (p. 27).

Aubry points out that the notions of act and potentiality first arise in the discussion of motion. But book Theta of the Metaphysics is dedicated to reshaping them in a way that applies to “being” as well as to motion. It is more particularly through act and potentiality that beings are constituted as the beings they are.

“Movement, in effect, should not be understood only in the order of interaction, but also in that of actualization. Or again: movement should not be understood only in the order of the correlation of an active dynamis and a passive dynamis, partitioning the field of efficiency into an agent and a patient, but in that of the correlation of dynamis and energeia” (ibid).

“But the dynamis found thus to be correlated to act, and which designates a state of being, is therefore irreducible to power: being in potentiality, coordinated with and determined by act, is neither passive nor efficient. Or again, potentiality is reducible neither to active power nor to passive power. The notion of potentiality serves to name the very possibility of the interaction of an agent and a patient in view of a change determined and finalized by act.”

“The correlation of potentiality to act nonetheless does not exclude that of passive power to active power: but it subsumes it, or subordinates it, insofar as it carries a greater intelligibility. It invites us to consider that which, in an impact, a meeting, or an interaction, is the occasion of an accomplishment. It is a point of view taken on that which, in movement, makes itself, that is to say not only makes itself but perfects itself…. Aristotle’s universe is not exempt from impacts and meeting: the substances that populate it are not Leibnizian monads…. The order of efficiency is a real order, but subordinate to that of finality” (pp. 28-29; see also The Four Causes Revisited).

“Potentiality is indeed for a being the real possibility, inscribed in the very qualities that give it its essence, of realizing that essence. Potentiality is the index and the principle of the becoming that leads a being to its accomplishment. It bears at the same time the distance between a being and what it has to be, and the possibility of crossing that distance. If act names the identity, real or realized, of being and the good, potentiality names this identity as to be realized. It inscribes into being at the same time as the concreteness of mediation, the possibility of perfection” (p. 29).

“The ontology of potentiality bears with it at the same time the thought of a possible perfection, realizable here and now, and that of failures, of accidents, of bad encounters, of unsuccessful mediations that could counter it” (ibid).

For Aristotle there is no “problem of evil”. Things are at one and the same time both imperfect and perfectible.

Again, I prefer to drop the term “ontology” altogether, because it is strongly associated with a (non-Aristotelian) approach to first philosophy that focuses on being as a noun, and in the sense of existence. Aubry retains the traditional term, but gives it a different meaning that is less prejudicial.

Far be it from me to claim to have the one true interpretation of these sharply contested points about Aristotle’s Metaphysics, but the key features of Aubry’s account seem to fit very well with my own examination of the text.

Aubry has emphasized the role of Plotinus in the historic re-interpretation of Aristotelian act and potentiality. I would note that the later neoplatonic school at Alexandria under Ammonius (5th/6th century CE) — especially Ammonius’ students Simplicius and John Philoponus — also produced extensive commentaries on Aristotle with a neoplatonic slant, which helped shape the way Aristotle was read in medieval times.

Ammonius argued that Aristotle’s first cause is after all also an efficient cause. Simplicius, who is also a major source for quotes from lost works in the history of Greek philosophy, added two more distinctly neoplatonic kinds of causes to Aristotle’s four. Philoponus was a Christian Aristotelian who defended creation from nothing, and was cited by Galileo as an inspiration for the impulse theory of motion. The impulse theory decouples physical motion from any teleology, paving the way for early modern mechanism.
