Power and Its Shadow

Omnipotence has been a problematic concept introduced by theologians in the monotheistic traditions. It has affected traditional metaphysics, the theory of knowledge, and politics. It has deep historical connections with political absolutism.

Ethics in the Socratic tradition take as a starting point something like the Kantian autonomy of reason, coupled with an agnostic but sympathetic view of religion.

For the Latin scholastic theologians, the autonomy of philosophical inquiry is only relative. But most stop short of a completely unqualified omnipotence, and do endorse a relative autonomy of philosophy. There is a long tradition of “faith seeking understanding”. This allows for a socially beneficial relation of benevolent mutual respect between theological and philosophical discourse.

For several centuries in the later middle ages, the main vehicle for expression of Christian theology consisted of meta-commentaries on the 12th-century theologian Peter Lombard’s commentary on the Bible, known as the Sentences. Lombard’s work was one of the foundations of Latin scholasticism. Over 1400 commentaries on it are known. Lombard was a student of the great Peter Abelard, but backed off from Abelard’s more controversial views.

Here I will largely translate and comment upon a brief survey of omnipotence in the Sentences commentary tradition by Olivier Boulnois. This introduction to his edited volume La puissance et son ombre: de Pierre Lombard à Luther (1994) touches upon many points of “historiographical” interest. The French volume focuses on Lombard’s distinctions 42-44, which are the parts dealing with omnipotence. It includes translations from Lombard himself, William of Auxerre, Hugh of Saint-Cher, Albert the Great, Bonaventure, Aquinas, Augustinus Triumphus, Duns Scotus, Durand of Saint-Pourcain, William of Ockham, Gregory of Rimini, and Martin Luther. My aim here is only to partially translate and comment upon the introduction by Boulnois, which is entitled “What God Cannot Do”.

“Can God walk, speak, lie, sin, die, make a mistake? Can he restore virginity? Do other than what he does? Create other worlds?…. Can God annul the most fundamental eternal truths or change them?” (p. 11, my translation throughout).

First, it should be noted that there is not just one concept of omnipotence. Its meaning has been the subject of great controversy in the past. We will see several competing versions in what follows.

Second, the medieval theological mainstream in fact recognized that there are some things God cannot do, or at least will never do. The great scholastics recognized that omnipotence has be qualified in some way in order to be at all defensible, even if they would not themselves phrase it that way. Their arguments are about where and how to draw the line.

“[T]o ask what God cannot do is to research the limits of the possible, and to pose a question that bears on one of the principal senses of being in Aristotle” (pp. 11-12).

The last is a reference to potentiality (dynamis in Aristotle’s Greek), which in the Latin tradition is mainly understood as a kind of power.

“The fundamental question becomes: what does the proposition ‘he can’ signify? To respond, it is necessary to articulate three concepts: power [puissance], ability [pouvoir], possibility” (p. 12).

Puissance and pouvoir can both mean power, but with different nuances. Puissance is standardly used to translate the potentia of the Latin tradition. Pouvoir is used to express ability, and also political power.

Boulnois asks, “With what power [pouissance] are we concerned here? With Aristotle’s being in potentiality (intermediate between being and non-being)? Or with the effective power [pouissance] to make be what is not? But doesn’t that presuppose power [pouissance] in the first sense?” (ibid).”

“Effective power to make be what is not” recalls the theory of creation in Aquinas.

Boulnois continues, switching to the other French term for power, “With what model of power [pouvoir] are we confronted? With the generosity of an overcapacity that dispenses in accord with its own goodness? With the arbitrariness of always-revocable decrees? With the fixation of laws in conformity with which power [pouvoir] must itself act to act legitimately?” (ibid).

Here we begin to see the connection with political power.

“What form of the possible do we encounter? This is the whole problem of modality: in the logical sense, everything noncontradictory is possible; but isn’t it necessary to add a second form of possibility, real possibility, that which can be effectively realized by causes?” (ibid).

Possibility and necessity are both modal concepts. I still need to write more about the ethical significance of modality. While preparing this post I dashed off another quick note.

“For the problem of omnipotence bears on the limit conditions of an order of the world and an order of discourse” (ibid).

Claims of omnipotence have a global impact on how we understand everything else, which is literally explicit in the very term. (“Omni” is Latin for “all”).

“The situation of the question of omnipotence in the organic unity of the Sentences leads to thinking the possible in terms of divine omnipotence, and not the inverse” (p. 15).

When two terms are identified or linked, questions of the order of explanation can acquire a large importance. Here this involves the relation between philosophy and theology.

“Peter Lombard analyzes divine power in a double way” (p. 16). “From then on, the question turns on the status of the possible in the divine understanding: does what is impossible for God come from God (as Henry of Ghent believed at one time) or rather from the inconsistency of the thing itself (Duns Scotus)? Or again, is it necessary to say that the question has no sense, it being given that there is a strict reciprocity between the reality of the possible and divine thought (Ockham, reprised by Luther)?” (p. 17).

“But the evolution of the interpretation explains the modern contradiction between divergent points of view: a God who is the cause of the possibility of eternal truths (Descartes), or is submitted to the necessity of the best of [all] worlds (Leibniz), or again is identical with the necessity of all his attributes (Spinoza)” (p. 18).

Omnipotence in Descartes underwrites a theological voluntarism. Infinity and a very different kind of omnipotence are the most important properties of Spinoza’s God, who is also equated with Nature. Leibniz uses another nonstandard kind of omnipotence, explicitly developing his metaphysical views in terms of a highly rationalized form of creationism.

“For the problem of omnipotence is first of all a problem of exegesis” (p. 19). “If God can do anything, isn’t it necessary to say that he can lie, be mistaken, be put to death? Doesn’t one go to the point of making God a bad power? Augustine strives to resolve the difficulty: ‘And its inability to lie is a great power of the Word’. As a consequence, divine omnipotence does not consist in being able to do all, except in an inadequate sense…. Thus omnipotence is defined simply as God’s power to not be prevented from doing all the good that he wills. Augustine carefully avoids defining omni-potence as a power to do all” (p. 20).

We are teetering on the edge of paradox here. It is precisely the qualifications of what initially seems like the unqualified par excellence that allow an ethical perspective to be recovered. At the very least, this is in great tension with the motif of unqualified power.

“If God cannot do something, that is because it is not a true power (walking, sinning, being mistaken are marks of imperfection)…. If all that God cannot do is only weakness and negativity, God will be in himself every positive power. ‘He can do all that power can do’. Divine omnipotence has become the infinite affirmation of power” (p. 21).

For the 11th-century monastic reformer Peter Damian, according to Boulnois, “The origin of nature is not subject to the same laws as nature. Creation ex nihilo affords a striking illustration of this: ‘Nature itself is made against nature’. Nature thus becomes identical to the will of God: ‘Nature itself has its proper nature, which is to say the will of God” (pp. 24-25).

“The whole question of modality is raised here…. For Aristotle, only the future is contingent…. But for the theologian, who speaks of the possible insofar as it is the object of divine power, even if a thing is, insofar as it is, it can not be…. Even if an event is realized, at the very moment when it is real, it is not necessary. For it could not be if it were not willed by God” (p. 25). “The restoration of [virginity, according to Damian] resembles a new creation, and it is not subject to any mundane law, even that of contradiction…. All power and all knowing are coeternal with God, sovereign creator of the world” (pp. 26-27).

Again modality comes up. The idea that the present state of the world is contingent is reasonable in itself.

Among the most radical claims associated with omnipotence is that God can change the past. Up to a point, it seems to me that we should affirm the contingency of the present as well as the future, but it is also very possible to go too far in this. What is challenging to specify is how to draw the line between good flexibility and bad arbitrariness.

For Aristotle, Boulnois says ” ‘That which is, when it is, and that which is not, when it is not, is necessary’. This principle does not bear only on a necessity of discourse. It also implies a real necessity. For Aristotle, the possible is nothing but being in potentiality, that is to say being which tends toward existence, and which at the end of an infinite time, will end by coming to be. There is what could be called a statistical interpretation of modality, according to which that is possible which was, is, or will be in an infinite time. Indeed it is a temporal interpretation, according to which there always will be a state of affairs in which the contingent is realized. Relayed by Maimonides, this principle is the basis of the celebrated ‘third way’ of showing the existence of God in Thomas Aquinas” (p. 32).

Aristotle’s “statistical” modality is not statistical in the numerical sense. He defines the necessary as that which is always true. “Always” may not be entirely air-tight. He also explicitly speaks of things that are true “for the most part”, and sometimes of things that are always true or true for the most part.

Boulnois continues, “The motif of this disequilibrium can be easily designated: it is the primacy of presence in all metaphysical analysis of manifestation. While the [more traditional] theologians, following Augustine, envisage temporality as a triple manifestation of the divine power in the past, present, and future, Bonaventure, in the manner of the Aristotelian metaphysics, places himself in the perspective of the thing in its evidence enunciable by the finite subject. He goes on to invoke an important argument: between the thing and its form of presence (be it a presence of the past or an existence in the present instant), there exists an analytic relation…. The presence of the thing is included in all manifestation. On the other hand the future, which is not yet, is not analytically included in the content of the thing that comes to be” (pp. 32-33).

There really was a “metaphysics of presence” in Latin scholasticism. The error is to attribute it to directly to Aristotle.

“From this point on, Thomas Aquinas, Giles of Rome, and Ockham pose only the question of the necessity of the past…. They no longer ask if the same question can be extended to the future. The reference to Peter Damian conceals a mutation of the problematic: instead of being posed from the transcendent freedom of God, the possibility of the contingent will only be envisaged starting from the human experience of the present. The ontology of the contingent becomes the possibility of finite freedom” (p. 33).

“All the commentaries on the Sentences, following the line of Peter Lombard, preserve the memory of the condemnation of Abelard by the council of Sens. In the spirit of this council, it is not permitted to think that God is necessarily determined to act and can only do what he does. The council Fathers, led by Bernard of Clairvaux, see in this prohibition a line that is not to be crossed. The omnipotence of God requires us to think that he can do what he does not do, omit what he does not omit, do what he does in another manner or at another moment, or similarly omit it. The divine omnipotence thus appears as sovereignly free, indifferent between acting and not acting” (pp. 33-34).

This is the point at which the thesis of omnipotence becomes dangerous.

“Peter Abelard himself was moved by a metaphysical principle, the principle of reason. God can only do what he does, because ‘God does nothing without a reason’…. Abelard does not admit that God can act against the order he has decided to follow…. God cannot go against his proper wisdom and his proper rationality. Reason imposes itself on him in being the form of his freedom. In a sense, Abelard is quite simply faithful to the patristic tradition that orients divine action toward the good. But he systematizes to the point of paradox, in limiting divine freedom by his wisdom” (p. 34).

The whole question about whether or not God can act “against” what he has “decided” is artificial, because it assumes an anthropomorphic and temporal notion of “decision”. If God is pre-eminently the Eternal as Augustine says, the temporal metaphor of decision is inappropriate.

“Peter Damian makes an equation between divine omnipotence and human freedom: what is possible for the human must at least be possible for God” (ibid).

This argument clearly depends on an anthropomorphic analogy. What is called “possible” for the human depends in part on the particular character of human finitude. It is not at all the same as what would be called “possible” for an eternal neoplatonic God exempt from all finitude. Frankly, it is not even clear that it is appropriate to speak of possibility in relation to God at all. Aristotle says that the first cause is pure act and entelechy. Augustine very strongly associates God with the eternal.

“As Peter Lombard well saw, contrary to the censors of Abelard who ignore the point, the position of Abelard is equally motivated by the principle of the best. As with Leibniz later on, the principle of the best follows from an interpretation of the principle of causality…. Abelard in turn follows the principle of causality, attested by Plato: ‘Nothing comes to be without a cause’. But he reinterprets it in the light of Christian theology, for which the cause of the created resides in the exemplary reason, the divine idea, model, or archetype by which God thinks the creatable before instituting it. It is in this sense that Augustine writes: ‘Who would dare say that God created things without reason?’ For Abelard, as a consequence, the world is created in a universal order, and in it no event escapes divine providence: nothing that appears contingent or due to chance comes to be outside of his prescience or his wisdom. Reason itself is a means of revelation. Despite the apparent disagreements between the Bible and Plato, a more profound reading of these two texts allows us to reconcile them, and to underline the identity between the rationality of God and his freedom” (p. 36).

“For in this problematic cause and reason are synonyms: ‘ratio vel causa‘, writes Peter Lombard…. The position of Abelard is indeed an important stage in the constitution of the principle of reason, between Plato and Leibniz. In Plato, the principle of causality, exterior to the demiurge, and the principle of the goodness of the cosmos are enunciated separately. For Abelard, the principle of reason has become interior to the divine wisdom, and conforms to the primacy of goodness. For Leibniz, finally, the principle of reason is no longer divine, but is identified with essence in general: every substance is the sufficient reason of its accidents” (p. 37).

“Without a doubt, the condemnation of Abelard played a decisive role here. We recall that Heidegger speaks of a ‘time of incubation’ of the principle of reason, already formulated since the birth of philosophy. But he does not respond to the question he himself raises” (p. 37). “In all the rigor of their terms, the condemnations of the council of Sens, in rejecting the application of the principle of reason to God, preserved the principle of reason in an incubator” (p. 38).

“If God creates a world, he cannot create it without what makes it a world: its order, the harmony of its parts…. God cannot create without: 1) what makes it a totality: that which is required for the achievement of a universe; 2) what makes its parts compatible with one another: the conditions of existence of creatures, one in relation to another; 3) what permits each of its parts to have sufficient consistency to possess the perfection of an essence and that of existing. The creation of a world results in the positing of a finite order, governed by the mathematical or musical principle of the harmony of the all, that is to say a certain proportion between the parts” (p. 39).

The strong notion of the coherence requirements of a world in Leibniz removes the usual arbitrariness from the notion of creation.

“This common problematic leaves room for a whole gamut of individual positions, from Albert the Great to Ockham. For Albert the Great, ‘if one places oneself in the point of view of being’, starting from the things that really exist, no better order is conceivable…. For Bonaventure, … God can make either a world different by its substances (but which is not really better, because it is incomparable), or a world different by its accidents (but that is really the same as this one)…. For Ockham, on the contrary the most probable position is ‘that which admits that God can make another world better than this one and specifically distinct from it’ ” (pp. 39-40).

Can God change eternal truths?…. Descartes raises this question” (p. 40). “God does not know truths as true unless he wills that they be so” (p. 41). “This debate has a long medieval history” (ibid).

Hugh of Saint-Cher is credited with originating the distinction between absolute and ordained power.

“Hugh of Saint-Cher [distinguishes] two aspects of divine power. As conditioned, it cannot be contradictory…. In the measure that the order of the finite is subject to the principle of contradiction, God cannot make two opposed propositions [both] true. But in itself, the same power as absolute is not subject to the principle of contradiction: nothing can limit its power” (ibid). “In this he anticipates in an unheard-of way the motifs and the difficulties of the Cartesian position, even if he does not like [Descartes] speak of creation or of eternal truths” (p. 42).

“Thomas Aquinas poses the same question, but he responds in a completely different way…. The divine power can only make what is possible, that is to say what is in the nature of things. The nature of simple essences and the principle of non-contradiction are the source of all their proprieties, and the divine power is in a way limited to these possibilities” (pp. 42-43).

Here Aquinas comes across as much more sensible than some of the others. In significant measure at least, he upholds the reality of secondary causes. A concept of God construed in a way that would invalidate all other concepts and reason itself seems fit only for sectarians.

“Subsequently, the debate develops in another form: is the impossible impossible because God so decided, or is it impossible by nature…? Henry of Ghent at one time held the first thesis, but ended up retracting it. Duns Scotus maintains an order that supposes the distinction of diverse moments…. It is only logical contradiction between the parts that grounds the formal impossibility of the thing, and indeed the divine intellection of that impossibility. There is an irrevocable anteriority of the possible and indeed of the impossible to the divine intellect. Possibility is imposed on God in the same way it is imposed on the human (that is to say in a univocal way)” (p. 43).

This is an important qualification about Scotus. Although he was regarded as a realist in the controversies about nominalism and realism, he generally comes across as an extreme voluntarist. But Boulnois is a leading Scotus scholar who has translated 2000 pages of Scotus and written a large book about him, so I assume he knows what he is talking about.

“For Ockham, on the contrary, power and the possible are correlatives. There is in the first instance an absolute real identity between divine intellect and will. And in addition, there is no anteriority of the possible to the intellect. The possible not being other than the non-contradictory, all the possibles are independent. No limit of the ontological consistency of the possible restrains the divine power…. Ockham accepts all the consequences of the identification of the absolute possible with the divine power…. There is neither an anteriority of the impossible to the divine omnipotence (Scotus), nor an anteriority of omnipotence to the impossible (Henry of Ghent), but a strict correlation” (pp. 43-44).

Once again, when two things are assimilated together, it may mean that one is being reduced to the other. For instance, I hold that there is no separately existing thing called will — that Aristotelian intellect, practical judgment, and wisdom better explain the freedom that some want to supernaturally explain by will. Ockham on the other hand is a voluntarist who sees will everywhere, and seems to deny that modality is anything real.

“An other is not always a world. It is only after Bonaventure that the theologians come to speak of a possible other world” (p. 46).

This is fascinating. I never would have guessed that Bonaventure would partially anticipate Leibniz on the subject of worlds.

“For Scotus, the order fixed by God appears to be necessary from the point of view of every inferior agent, when it acts according to that order…. In the order instituted by God (nature), starting from contingent hypotheses, the laws of nature are necessary for the finite. They draw their necessity from the fact that it is God who invests them with their legality” (p. 47).

From this point of view, necessity only comes about from divine will. Sheer will conceived as a brute fact is thus said to come before justice or wisdom. This undermines all criteria.

“For Aristotle, the concept of world is that of a totality: there is only one possible world, and it is a fortiori the best” (p. 48).

But the argument that this is the best world because there is no other is a very weak one that Aristotle does not himself make, because he does not consider alternate worlds, and also does not consider the world to be created.

“For [Peter Damian], even a good that is never produced is in the power of God, the reason for its retention residing in the secret of his good will. His analysis results in distinguishing two poles in the divine power: on the one hand, the omni-potence taken in itself, which no im-potence can encumber, and on the other hand the order in which it is exercised, and which can explain that omnipotence is not manifested…. Thus, Peter Damian constructs the conceptual armature between two poles, which later took the name of absolute power and ordained power” (p. 53).

Peter Damian was an 11th-century monastic reformer who campaigned vigorously against corruption in the Church. He advocated solitude and ascetism, and reportedly introduced practices of flagellation that were regarded as too extreme by some. In the early 20th century, it was argued that Damian exempted God from the principle of non-contradiction, but this has been rejected by later scholars. He wrote a treatise on omnipotence arguing that God can restore virginity, but according to the Stanford Encyclopedia of Philosophy, he neither claimed that God can change a past event, nor that God can contradict himself.

What will become the distinction between absolute and ordained power allows appearances to be (mostly) saved while the claim of absolute power is maintained. I would note that this is an elaboration of Augustine’s reconciliation of miracles with natural causes, which treats natural causes as God’s established habits that are not invalidated by miracles. It will often be expressed using Aristotle’s notion of things that happen in a certain way “for the most part”, but there is no indication that Aristotle intended this as a way of leaving room for miracles. What happens for the most part in Aristotle involves variation in the way that the order of nature works out in particular cases, not suspension of it or exceptions to it.

“The ordained power has for object that which has been preordained, or disposed by God. It is a preordination of the possible in the divine understanding, and not the order of the real outside of God. Indeed it coincides with his prescience…. The ordained power does not presuppose order and is not determined by it; on the contrary, it is it that determines it in determining itself: it prefigures it, it is the pre-supposition of order. It is the pre-order” (p. 55).

According to this view, the order of the world corresponds to the “habitual” operation of creation. The habitual order is subordinate to the power of creation that produces it. The habituality of the created order is real, but it also has real exceptions in the form of miracles.

According to Boulnois, “Absolute power and ordained power form a couple of concepts, a dialectic, such that we never find one without the other. There is no theology of absolute power without the theology of ordained power. What we find instead are different ways of thinking this dialectic” (ibid).

“The object of absolute power is identical to the object of divine wisdom, to the totality of what is possible for God. The object of ordained power is identical to the object of the principled will of God” (pp. 55-56).

“For God does nothing without prescience. His action is subordinated to the order predetermined by him, and can never depart from that order. As a consequence, operative power is subordinated to ordained power; and reciprocally, God never operates directly by his absolute power. Absolute power taken in itself, naked, is not operative” (p. 56).

It was I and not Boulnois who earlier brought Augustine’s justification of miracles into the discussion. I much prefer Aristotelian natural variability to the Augustinian theory of miracles. But on the older view Boulnois is characterizing here — that God never acts directly by his absolute power — it would seem that there could be no exceptions to the ordained order. This seems consistent with Augustine’s rigorous view of eternity, but it is in tension with Augustine’s justification of miracles.

It appears that Duns Scotus (1266-1308) was instrumental in changing the traditional Augustinian pattern in these matters. Boulnois is a world-class expert on Scotus, so he is well qualified to point this out.

“While reprising these classical elements, the interpretation of Scotus breaks with his predecessors, for three reasons: 1) The theory of absolute power and ordained power is extended to every free being. 2) In reprising the distinction between fact and principle, Scotus conceives the two members of the distinction as two ways of acting and not simply as two powers. God intervenes in fact by his absolute power to modify what is in principle the course of things. 3) Even when he has chosen an order, at the same time and from the same point of view, God can do that which he did not decide upon. The divine power is open to an array of synchronic possibilities, and the state chosen in fact does not exclude other possibilities” (p. 56).

Each of these three points is significant: 1) Beliefs about human free will come to be patterned on a pronouncedly voluntaristic interpretation of divine omnipotence. 2) Fact is for possibly the first time asserted to be more decisive and more inclusive than principle or essence. Reason must accommodate presumed facts, rather than governing their interpretation. 3) Far from being stably grounded in eternity and essence, order of all kinds is now treated as fundamentally contingent and revocable.

In 20th-century scholarship, the emergence of such “modernist” views was most often associated with William of Ockham, who as the arch “nominalist” in accounts of the 14th-century debate about universals has been treated as diametrically opposed to the more traditional “realism” attributed to Scotus. But according to Boulnois, Scotus was the decisive innovator with respect to these views about will, fact, and order.

“It is this interpretation that seems to have had the most influence on subsequent medieval thought.”

“There are two models, fundamentally distinct: 1) A logical model, for which absolute power is the power capable of the totality of possibilities (of all that is non-contradictory), and the ordained power corresponds to the choice of a particular order. 2) An operative model, for which divine intervention de potentia absoluta is a possibility of modifying in fact that which is in principle the course of things. What is outside of order is not disorder but fact.” (ibid). “For Scotus, the model is no longer a logical model, but an operative model. He no longer distinguishes two forms of power but two forms of action (according to the law and outside the law)” (p. 57).

What is described as the traditional view here tends to make order overly strong, presuming it to be capable of explaining all facts, while the “modernist” view makes fact overly strong, tending toward a proto-fundamentalist denial of the need for interpretation, and at the same time shrinking the scope of order so that fact always exceeds it.

As Boulnois argues more generally in his big book on Scotus, L’Être et représentation (“Being and Representation”, 1999), this historic transformation is too large to be attributed to a single figure, but Scotus is nonetheless at its center. Modern large-scale interpretation of the history of Latin philosophy has generally centered on Aquinas, who was canonized as a saint in 1323, and specially declared by the Pope to be central to Catholic philosophy in 1879 after the rise of neo-Thomism.

(From a broad point of view, the “moderate realism” of Aquinas has much to recommend it, but one-sided emphasis on Aquinas has obscured the real diversity and complexity of Latin philosophical views and the important role of numerous others, including Scotus. The pragmatist Charles Pierce rather casually called himself a Scotist realist. Heidegger wrote his dissertation on Scotus, but in later work tended to reject Latin philosophy with a very broad brush, without addressing important historical detail.)

“No more than his predecessors does Scotus say that God acts by an absolute power, but only that he can act otherwise than he does (and it is in this that his power is absolute). This has no immediate operative content…. Duns Scotus does not say that God acts by his naked absolute power, but precisely always, according to a beautiful oxymoron, ‘in the manner ordained by his absolute power’. What characterizes the position of Scotus, more than the operative model of absolute power alone, is at the same time the extreme opposition of this dialectic between the two concepts and the possibility at every instant of one toggling to the other. To safeguard divine freedom, Scotus creates an infinite oscillation between an instituted juridical order and a de facto power that is nonetheless not disordered and immoral” (ibid).

What Boulnois calls a beautiful oxymoron in Scotus, the de facto claim of an infinite oscillation between order and fact — evinced by the phrase “ordained by his absolute power” — seems to collapse the evolved distinction between ordained and absolute power. Perhaps this is why Scotus was called the “subtle doctor”. But the implications of this position are not at all subtle. They are quite dramatic.

“What characterizes the end of the Middle Age is at once the inflation of arguments resorting to absolute power and a fragmentation of models allowing it to be thought” (p. 58).

Boulnois cites Avignon Pope John XXII’s blunt declaration that the absolute and ordained power of God are the same thing. John apparently used this to justify a politicized claim that salvation can only be achieved through the institutionalized sacraments of the Church. “All that which is ordained by God is irrevocable” (p. 59). This was a time of bitter conflict between the Avignon Pope and the Holy Roman Emperor Louis IV. It was under John that Aquinas was canonized as a saint. John was also the one who formally declared witchcraft to be a heresy.

We saw above that William of Ockham also emphasized the inseparability of absolute and ordained power. But he apparently used it to argue for the opposite practical conclusion, that law and ordained power can always be surpassed by fact and absolute power, and that salvation can be achieved through faith alone. Under the protection of Louis IV, Ockham accused the Pope of heresy.

(From the point of view of the logical pragmatics I have discussed in reading Brandom, the formal identification of two things with different connotations can be interpreted as a reduction of one to the other, or of the other to the one, or as a nonreductive combination of the two. Different connotations imply different pragmatics or conditions of use.)

Boulnois says that Ockham interprets the thesis of the nonseparability of the nominally distinct powers (absolute versus ordained) in terms of its consequences for the power’s object (the world), rather than in terms of its subject (God).

“John XXII insists on the fact that the identity of divine power entails the invariability of the order chosen by God…. For [Ockham], the theory of John XXII comes back to saying that the order of the world cannot be other than it is. From this it follows evidently that no creature can do what it does not do…. He sees in this a resurgence of Greco-Arabic necessitarianism, an error condemned in 1277. And to say that humans can only be saved by the institution is not only an error, but a heresy: in fact, many humans are saved by their faith without being baptized” (p. 60).

“Greco-Arabic necessitarianism” is another exaggeration. Among the Greeks, the only real necessitarians are the Stoics. Alfarabi, Avicenna, and Averroes do all seem to slant things in the direction of objective order and necessity, but the radical voluntarism of Ghazali seems to have been more historically influential in the Arabic tradition.

“For Ockham, order is always a de facto order, a complex of contingent and revocable singularities. It is thus the object of ordained power; but what God can do (in principle), even if he never does it, is the object of absolute power. There is here an extraordinary cross-chase in relation to Duns Scotus. What the one calls the object of ordained power, the other calls the object of absolute power, and vice versa. The fact and the principle exchange their role” (ibid).

On Boulnois’s account, Ockham is a less radical voluntarist than Scotus.

“For Ockham, it is necessary to thus understand the distinction ‘power to do something’: the expression is sometimes taken according the laws ordained and instituted by God, and of these things one says that God can do them by his ordained power. In another way, ‘power’ is taken in the sense of power to do anything that is not self-contradictory, that God has ordained that he will do or not do, and of these things, one says that God can do by his absolute power. The ‘ordained power’ indeed does designate the order established by God, as in Duns Scotus. But the ‘absolute power’ designates not his de facto power, but only everything that is not contradictory: it has a logical sense and not an operative one (since it designates what God does not do); he returns quite simply to the traditional sense admitted before Scotus” (pp. 60-61).

“[Ockham’s influential student] Adam Wodeham explicitly cites two interpretations of absolute power…. Adam Wodeham clearly thinks ordained power as an order instituted regularly and capable of dispensation, like Scotus and Ockham. But he is also aware of the existence of two models for thinking absolute power: that of Duns Scotus, for whom the power to do the contrary of the established order is absolute, that is to say autonomous and absolutely capable of acting; and that of Ockham, for whom the absolute power of God is subject to the logical principle of contradiction. For Scotus, even when God has ordained the contrary, he can do something by his absolute power. For Ockham, God can only act by his absolute power if there is no contradiction with what he has ordained” (p. 61).

“As a consequence — and contrary to received ideas — the great epistemological rupture of the 14th century was effectuated by Scotus more than by Ockham…. [Scotus] is infinitely more revolutionary, in admitting that God has a de facto power that is other than the power in principle without being immoral. Nonetheless, the position of Ockham and that of Scotus converge on one point, essential for theological ethics: even if, by the ordained power of God, the human can only be saved by baptism and entry into the institution, by the absolute power of God, the human can be saved without Church or charity…. One of the distant consequences of this hypertrophy of absolute power will be the possibility, vigorously enunciated by Luther, that there is a predetermination indifferent to good and evil” (p. 62).

Luther argued for justification by faith alone, traced all authority solely to the Bible, and tended to emphasize its literal word.

“It would be exaggerated to make the new theory of divine power bear all of the motif of the metamorphosis of theology after Scotus. It would also be exaggerated to try to reduce everything to the new theories of intuition or of the primacy of will. First of all, Scotus is only the spokesman for a whole generation of thinkers who each contributed to the restructuring of theology” (p. 63).

But these caveats address only certain over-simplifications of the historical interpretation Boulnois develops.

“It is the triangle of power, knowledge, and will that is modified in its entirety. In the human as in God, power [pouvoir] becomes a power [puissance] to act in principle or in fact. Power remains a capacity to act according to an order (interpreted juridically as a law), but it also becomes the capacity to act outside the law or against it. Furthermore, for thinking of the problems of beatitude from the side of common abstractive knowledge, there developed a theory of intuitive knowledge of the singular contingent. Finally, for the Franciscan theologians above all, freedom of the will is an innate quality” (p. 63).

On the threshold of modernity, new voluntaristic super-powers are attributed both to God and to the human. The alleged fact of voluntaristic will is no longer constrained by an orientation toward the good.

“As a consequence, willing is no longer tautologically willing the good. But reciprocally, what God wills is ipso facto the good. On the edge of the new theology of omnipotence, the theories of intuition and of will will be adjoined, to construct a new model of practice and of epistemology. With this new device, it is the whole harmony between the transcendentals, being, truth, and the good, that is disrupted. The objects of power, of will, and of knowledge are no longer necessarily aligned” (pp. 63-64).

“Conceiving divine intervention de potentia absoluta as a real possibility led to an undermining of the intelligibility and predictability of natural phenomena. The order of the real no longer appears except as a descent into particularity in the ocean of possibles. This disjunction has a paradoxical consequence: philosophy is all the more free to expound the necessity of the order of the present world, while the theologian makes contingency surge into this world here, when he does not invoke an infinity of other possible worlds. The present order can become an absolute, and the absolute can contain an infinity of other orders. The order and the absolute are disseminated in an indefinite variation of hypothetical orders. The order and the absolute are no longer articulated; they pass one into the other” (p. 64).

As Boulnois says, treating divine intervention in the world by absolute power as a real possibility tends to undermine intelligibility. I would add that this undermining of intelligibility undermines ethics as well.

“This renewal of the problematic figures an evolution of theology. It makes God less and less human, less and less reached by knowledge of the order of the universe, less and less oriented toward the norm of the good. Divine omnipotence thus founds a ‘skeptical’ movement, which has consequences for the theology of justification (from Scotus to Luther). The order of salvation appears more and more contingent…. The equilibrium between the order of the world and the omnipotence of God attained in the Sentences of Peter Lombard ended up a victim of its own success. After being articulated with nature, the supernatural becomes omnipresent, and finally suspends all autonomy of the order of nature. There is no longer a consistent finite order. Omnipotence figures a more and more uncertain order of the world, and results in a complete concealment of God and his plans from the human. God is so unknowable that his attributes are founded in the brilliance of his omnipotence, reachable only by faith, and not allowing any certainty to exist. Following this metamorphosis, God, the object par excellence of theological intelligence, who was at first thought of as ineffable, will be finally named as incomprehensible. The world will appear as a labyrinth of axiomatics and exceptions, in which individuals are toys” (pp. 64-65).

This omnipresence of the possibility of supernatural intervention, outside the order of nature — and the correlated suspension of all autonomy of the order of nature — are what undermine intelligibility.

“It is now the model of political power [pouvoir] that serves to think the divine power in an identical, univocal sense, even in a particular case: all power can be exercised either juridically, or de facto” (p. 65).

“By a cross-chase of which history has the secret, these ‘absolutist’ arguments will serve later for the exaltation of monarchic power against pontifical pretensions. In Jean Bodin, they serve to describe the absolute power of the prince. This theory leads to a reinforcement of political absolutism — and simultaneously to an evanescence of the predictability of the law of nature” (p. 66).

“The theme of absolute power grounds the work of Duns Scotus in three dimensions: ontological (the action of every free agent), juridical (the king and his realm), theological (God and his decrees). This origin reveals a structural correspondence between the modern concepts of individual freedom, of divine power [puissance], and of political power [pouvoir]” (ibid).

“The black sun of omnipotence shines with a paradoxical light. When power wants to be without shadow and without limits, it accumulates within itself the night in which all evils are absolved; it endorses dark things and obscurity. On the contrary, the power that is incapable of evil and excludes it is a pure light without darkness. It does not suppress the shadow, or assume it, or absolve it, but dissociates it from itself and separates it from its sharp light. But for this it must be a power capable of lacking power” (p. 68).

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).

Separate Form?

“Lambda 3 goes on to show that form cannot be separate” (Aubry, Dieu san la puissance, 2nd ed., ch. 5, p. 168, my translation throughout).

I have always been rather baffled by interpretations of book Lambda that claimed to find evidence there that Aristotle finally revives the notion of separate form he so thoroughly refutes elsewhere.

“The first object of Lambda 3 is to examine the well-foundedness of the Platonic arguments in favor of the separation of form — or its pretension to the status of ousia [“substance”]. The permanence of form in generation can be invoked in support of such a thesis” (ibid).

“[F]orm, even if it well fits the Platonic criterion of ousia that is permanence, does not meet the specifically Aristotelian criteria. Here the appeal will be to that of tode ti, of being a ‘this'” (ibid).

“[T]he text opens with a new formula of change, which, contrary to the previous ones, takes into account its cause” (ibid).

As Sachs renders the full passage that she cites in part, “For with everything, something changes, by the action of something, and into something: that by the action of which it changes is the first thing that sets it in motion, that which changes is the material, and that into which it changes is the form. For it comes into being either by art or by nature, or else by fortune or chance. And next after this is the fact that each independent thing comes into being from something that has the same name (for this is true both of natural independent things and of the rest). Now art is a source that is something else, but nature is a source that is in the thing itself (since a human being begets a human being), while the rest of the causes are deprivations of these” (Metaphysics, p. 233).

Aubry notes that this language appears to be a bit of a regression, since matter has already been superseded by potentiality in Lambda chapter 2. But she explains that chapters 2 and 3 constitute a pair concerned respectively with matter and form, and chapter 2 did not yet address form.

She points out that Aristotle goes on to mention three kinds of substance, among which form is conspicuously not included. “What are enumerated are matter, which is only in appearance a tode ti; phusis [nature], which is at the same time a tode ti and a hexis [acquired disposition]; and finally, the composite, or individual realities, the kath ekasta like Socrates and Callias. Where we might expect the term form, we instead find that of phusis, which will be qualified again as hexis. For phusis is precisely a form realized in a matter, stabilized as hexis at the end of a process. Such an enumeration already signals that form as such cannot be counted as ousia, and cannot be separate, in the sense that it does not exist apart from the composite” (p. 169).

“In Zeta 8, it was already the intervention of the criterion of tode ti that allowed it to be established that form does not exist apart from (para) the composite, and thus to reject as superfluous the hypothesis of the Platonic Forms, since, at least in the case of natural beings, it is indeed an individual — and a concrete composite — that engenders another. But besides Zeta 8, it is necessary to refer equally to Eta 1…. Eta 1 makes intervene, in addition to the criterion of tode ti, the criterion of khoriston, which, as we have underlined, is equally present in Lambda 1. The examination established that matter is only a tode ti in-potentiality, dunamei; while form is only [a tode ti] insofar as it is to logo khoriston [separate according to the formula, or in speech]; and only the composite is khoriston haplos [separate simply]” (pp. 169-170).

“Like the criterion of khoriston and even dissociated from it, the criterion of individuality indeed leads to only counting the composite of matter and form as ousia” (p. 170).

“[I]n the case of art, there can be form without matter, but the form thus considered is nothing but tekhne [art] itself, that is to say in fact the form such as it is conceived and envisioned by the artisan. In the case of phusis, the principle of synonymy, the permanence of one same form transmitted from one individual to another, is sufficient to explain how we are led, as Plato did, to assert that there exist distinct forms of natural substances. But we can conclude from this neither that they are separate, nor that their character is that of tode ti and of ousia.”

“This would presuppose that the forms exist apart from and independent of composites, and in particular that they are capable of pre-existing as well as perhaps surviving them. But in truth, the existence of the formal cause is simultaneous with that of the composite. Certainly health is distinct from the healthy, and sphericity from the bronze sphere, but health and sphericity do not have full existence, that is to say do not exist as ousia except as instantiated in the cured patient, the completed sphere” (ibid).

“At the end of the whole formed by Lambda 2 and 3, we are indeed in possession of a positive result: matter, conceived kata dunamei, can be extended from the corruptible sensibles to the eternal sensibles; but also a negative result: form cannot be separate. Each of these results already contains elements of a response to the guiding questions posed in Lambda 1: whether or not it is possible to unify the principles of substance; and the nature of the separate. One term is still missing: that of energeia, in which will reside the definitive response to these two questions” (p. 171).

In discussing Lambda 2, she emphasized the substitution of potentiality for matter. Here in passing she suggests that alternatively, we could consider that matter has been redefined along with potentiality. But which alternative we endorse is really just a question of the optimal use of words. The old understanding of both matter and potentiality has been left behind.

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.

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 [ZetaEtaTheta], 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 dunamisenergeia (or — and it is necessary for us to ask ourselves about this variation, of their dative form dunameienergeia) 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.

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 dunamisenergeia 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.

Next in this series: Act as Separable

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.

The Relativity of Dynamis

“Up to the end of Theta 5, even though the end of Theta 3 had initiated the ontological inquiry, it is principally the kinetic dunamis [potentiality] that we have explored. The first lines of Theta 6 close this first moment: now that we have treated dunamis in relation to movement, it is necessary, writes Aristotle, to take an interest in energeia [act]. We note anew the dyssymmetry already raised: it is the study of energeia, not of dunamis, that presides over the extension of energeia as of dunamis from the kinetic sense to the ontological sense.”

Energeia and dunamis will be initially characterized as two distinct sides of one thing of huparkhein, of existing. They are thus designated as two distinct modes of being, where the difference, nonetheless, can be known only through their opposition. This opposition constructs in-potentiality as relative to energeia [act as “in-a-work-ness”, or something realized in a work] — thereby rejoining the definition of dunaton in Theta 3 as that of which the act can exist (huparkhe he energeia). Thus, the in-potentiality is to be understood as that of [the statue of] Hermes in the wood, or that of the half-line in the whole line, because the one and the other can be separated…, or again as the way in which someone knows something without contemplating it, if it can be contemplated. If in-potentiality thus finds itself characterized only relatively to energeia, the latter in its turn is not explicitly defined, but implicitly identified with what is separated in the first example (the Hermes and the half-line), and with the exercise in the second (contemplation)” (Aubry, Dieu san la puissance, 2nd ed., ch. 4, p. 130, my translation throughout). 

“Theta 8 will show, in conformity with what Theta 3 already affirmed, that it is the ontological sense [of dynamis and energeia] that is primary: it thus appears that movement can be called energeia insofar as it is taken as the manifestation of being, or again of the work, or again of the end. It is indeed the kinetic sense that will appear as an extension of the ontological sense, and of a more determinate sense by virtue of which act is not only another name for being, but for being in the end” (p. 132).

Aubry points out that the last lines of Theta 6, which somewhat confusingly emphasize a distinction between whether an end is immanent or not, have been regarded by leading scholars (including Werner Jaeger and Miles Burnyeat) as an addition to the text.

She notes that in Theta 8, “we will read that movement can be considered as a form of energeia insofar as, in certain cases, it can serve as an end…. Far from being opposed to energeia as that which does not have its end in itself to that in which the end is immanent, kinesis will be presented as a form of energeia insofar as it can serve as an end, which leads us to suspect the last lines of Theta 6″ (p. 133).

“As was already the case in Theta 5, we are here formulating restrictive conditions, which rule out saying that any matter whatsoever is in-potentiality for any form whatsoever. In-potentiality is only said of a determinate matter in relation to a determinate form. More precisely, in-potentiality indicates the very possibility of the relation of such a matter to such a form. Even in formulating the conditions of the equivalence dunamishyle posed by the analogy, Theta 7 thus justifies the formula of Eta according to which ‘the proximate matter and the form are one and the same thing, the one in-potentiality and the other in act’.”

“If in-potentiality names the capacity of matter to acquire a determinate form, the division of dunamis from hyle is no less maintained, at the same time as it is given measure. In effect, for the products of tekhne [art] as well as for the phuseis [natures], we can establish a common criterion: the uniqueness of change. Potential is thus distinguished from the indeterminate possibility in virtue of which any matter whatsoever could [supposedly] acquire any form whatsoever. But it is also distinguished from the actual….”

“If Theta 7 prolongs the analyses of Theta 5, a change of perspective is also evident: in effect, the question posed is no longer to know only of what a thing is capable, dunaton, but for what it is in-potentiality, dunamei…. A double displacement is marked here: first, the distinction between active power and passive power, with which we began, is effaced before the notion of in-potentiality…. [And second,] the notion of in-potentiality thus serves to name, beyond the distinction between active power and passive power, the very possibility of the interaction of an agent and a patient with a view to a determinate change.”

“In what follows, we will ask not only when a thing is in-potentiality for another, but when a thing is in-potentiality in another: in so doing, we ask not only about in-potentiality as a principle of change, but about in-potentiality as a mode of being” (p. 134, emphasis in original).

“This transition will be completed in chapter 8….”

“The text [of chapter 8] opens with a redefinition of dunamis…: this new definition, which is more expansive, is in effect formulated in such a way as to include natural beings…. In the same way, natural beings are defined in Physics II as ‘having in themselves a principle of motion and rest’. Nature can thus be said to belong to the same genus as dunamis, since it is an immanent principle of movement. Thus redefined, dunamis will be envisaged in the order of immanence more than in that of transitivity: we thus integrate the results of the previous chapter, which defined in-potentiality at the conjunction of the active and the passive, and beyond this distinction. The extensive definition of dunamis thus marks the definitive adoption of a new point of view, in virtue of which potentiality [puissance] will no longer be considered in the order of the correlation of agent and patient, but in its relation to act. Dunamis will thus appear as the principle of a movement that can take place within something, which is essentially teleological [finalisé] (even if it can have no other end than itself), and which is a transition from a certain non-being to full reality” (p. 135, emphasis in original).

Potentiality and Contingency

“[T]he rational powers are powers for two contrary effects: but two contraries cannot be actualized at the same moment by the same power. What is thus necessary (ananke) — but this time by a logical necessity, dictated by the principle of non-contradiction — is that there intervenes, in addition to dunamis, another principle: desire or deliberated choice, orexis or prohairesis, which chooses between the two contraries.”

“We can thus reformulate the definition so that it serves for the dunaton kata logon: it is necessary (ananke) when that which is capable according to reason [what was called a rational power] desires something for which it has the power, that it does that thing. The necessary sequence begins this time from the power insofar as it is modified by desire and/or by choice — and thus by liberty. It remains that, here again, the attribution of such a power implies the taking into account of the circumstances of its effectuation. According to this new determination, that is possible which is decided or desired by the agent, and which the circumstances allow (which its deliberation must take into account)” (Aubry, Dieu san la puissance, 2nd ed., ch. 4, pp. 127-128, my translation throughout).

Aristotle doesn’t literally offer a new definition of possibility at this point, but the effect is similar. In Sachs’ translation, he says that one having a rational power too “has the potency in the sense that it is a potency for acting, and this is not in every situation but when things are in certain conditions…. [E]ven if one wishes and desires… to do contrary things, one will not do them, for… there is no potency for doing them at the same time, since a thing will do the things it is capable of in the way that it is capable of them” (Metaphysics, book Theta ch. 5, p. 173).

All power or potency for Aristotle is the power to do something definite, and every power to do something definite is capable of doing it only under certain conditions. Consequently, there could be no such thing as an indefinite or unlimited power.

The emphasis on contraries in the case of rational powers is a little confusing, but it seems to be a further consequence of the notion that all power is definite. He seems to consider deliberation about the use of definite powers as revolving around the question whether to use them or not, which does thus acquire a kind of binary flavor. But it seems to me that a being having multiple powers might also deliberate about which of several to apply in a given situation.

What is really essential here is that rational power belongs to beings that deliberate. This is what makes it “rational”. And Aristotle sees a kind of “rational” (rather than physical) necessity that a being that desires or chooses something and has the power for it, will do it. But because it incorporates deliberation and choice among its conditions, this kind of necessity is not that of determinism. It is a hypothetical necessity that is compatible with contingency.

Returning to Aubry’s argument, “Proairesis [choice based on deliberation] thus intervenes as a principle of contingency, capable of inaugurating a necessary causal sequence. If the circumstantial definition of the possible leaves no place for logical possibility but tends to identify possible and potential, on the other hand the distinction between potential and actual is maintained.”

“But to this it is necessary to add — and this is what Theta 8 will do — that power considered in itself, and not in relation to its effect, is a principle of contingency. Every power, taken not as principle of action but in opposition to act, considered thus in its ontological determination and not only a kinetic one, is the place of an essential indetermination” (p. 129).

So by a sort of dialectical twist, Aubry momentarily attributes a kind of determinism to Aristotle, and then refutes it two pages later. On pedagogical grounds, I don’t favor the deliberate construction of unnecessary dialectical surprises, just as I don’t stylistically favor the kind of construction that first seemingly makes an unqualified statement, then adds qualifications later on. If a statement will later be qualified, it is good to give some indication of that up front. But in context this a minor point, and partly a personal preference of mine that Aristotle doesn’t follow either. The thing to emphasize here is that Aristotle simultaneously argues for an essential contingency in all power that is incompatible with determinism, and at the same time for the role of a hypothetical, delimited necessity that is compatible with contingency.

“It is on this essential contingency of power that the antideterminist argument of On Interpretation rests. Aristotle there distinguishes not only, like in Theta 4, the impossible from the false, but the possible from the true: of certain possible propositions, one cannot say in advance whether they will be true or false…. The possible is thus distinguished at once from the actual, the necessary, and the true” (ibid).

She summarizes Aristotle’s famous discussion in On Interpretation of the sea battle that may or may not happen tomorrow. At the most obvious level, this has to do with human deliberation and choice.

“But again Aristotle gives this another extension: if the future depends on decision and on human action, it is also true, and this time in a general (holos) manner, that ‘in all that which does not act always, there is a possibility of being and of not being. This indetermination in virtue of which the future must be called contingent, and the propositions concerning it neither true nor false, also affects events involving irrational powers” (p. 130).

Here we come full circle, to Aristotle’s rejection of strict determinism in the action of natural powers as well rational ones.
