At this point we are starting to sum up the results of Aristotle’s Metaphysics book Theta on potentiality and act. Aubry now makes a stronger statement that what it is in itself to be something in potentiality or in act can only be made clear by considering the relation between the two.
“In fact, and always in continuity with the analogy of Theta 6 [between various particular cases of something being in-potentiality and in-act], we begin by considering the relation of dunamis and energeia — that which, according to Theta 6, is the unique means of understanding these notions in themselves, but which also serves to justify the various equivalences posed by the analogy” (Aubry, Dieu san la puissance, 2nd ed., ch. 4, p. 135, my translation throughout, Becker number citations to the Greek text omitted).
“This relation is defined according to a triple anteriority: energeia is anterior to dunamis at once according to the formula, logoi; according to the substance, ousiai; and, but only from one point of view, according to time” (ibid).
“Of an individual in-act, one must say in effect that she is engendered from in-potentiality by another individual in act…. In-potentiality is no longer presented here as a principle of movement, but as a transitory state between two acts. And energeia in its turn is no longer identified with movement, but with the state of that which moves [something else], insofar as it is identical in form with the moved” (p. 136, emphasis in original).
This case applies to biological reproduction.
“Anteriority according to the formula is qualified as evident: it is in relation to act that one defines in-potentiality” (ibid).
“From [Becker index] 1050a4 on, we go on to explore the third relation of anteriority, that according to ousia [“substance”; what it was to have been a thing]. Here we are at the heart of Theta 8, and indeed of Theta in its entirety, since here the triple transition will be accomplished — from the kinetic sense to the ontological sense; from the model of the transitivity and the correlation of powers to the model of the dunamis–energeia correlation insofar as it applies to transitive change as well as to immanent change; and finally, from the model of efficiency to the teleological model.”
“The anteriority according to ousia is not initially given as an anteriority in the order of existence, but as an anteriority in that of form and of essence…. That which is anterior according to ousia is posterior according to generation: the adult is posterior to the infant…, even though in the latter is found the form that is not fully present. But this inversion from one order to the other is explained by the fact that the anteriority of act according to ousia is that of form as end: the act [the adult] is ‘that for the sake of which’ for generation.”
“Here we rejoin the analyses of books Zeta and Eta, where the substitution of the notion of act for that of form proceeds from the adoption of an etiological, and not only logical, point of view, by which the form is considered in its causal function, and envisaged as end” (ibid).
In a composite of form and matter, the form that is considered as end and not only “logically” will be in a sense identified with the composite as a whole, i.e., with the form as realized in matter.
“The anteriority of act according to ousia is that of the end, that is to say of the form as the term of a process that realized it in a matter — and indeed, in the composite that book Zeta qualifies as ousia malista [ousia most of all].”
“For it is this anteriority of act as end that provides the key to the necessary correlation of dunamis and energeia. One does not say only that energeia is to dunamis as that which builds is to the art of building, or as that which sees is to that which is given to view, but that it is for building that one understands architecture; for sight that one has sight; for contemplating that one has the power of contemplating. Act, from this point on, does not appear only as that in relation to which one defines power, but as that for which power is” (p. 137, emphasis in original).
She quotes Aristotle, “The act is the end, and it is in view of it that the power is acquired” (p. 137).
“We integrate here the results of Theta 7 for justifying the equivalence between matter and in-potentiality; for what justifies this equivalence is that the matter is teleologically determined by the form…. As at the end of book Eta, act serves here to name the unity realized from the matter and the form” (ibid).
Act serves “as another name for the ousia malista [ousia most of all] of book Zeta” (p. 138). And this is none other than the composite of form and matter.
“The ontological sense of energeia nonetheless is presented as being at the foundation of the kinetic sense; if movement can be called energeia, it is insofar as we take it as an index of being…. From now on, what justifies the equivalence between energeia and kinesis is that movement can also be telos. And if energeia and kinesis can be called entelekheia, it is not only in the sense where they name effective and complete being in opposition to the incomplete being that in-potentiality says, but because they name that being which, for in-potentiality, is its end” (ibid).
She quotes Aristotle, “For the ergon [completed work] is the end, and energeia is ergon. This is why the term energeia is derived from that of ergon, and tends toward entelekheia” (p. 139).
She continues, “Ergon thus intervenes as the mediation between energeia and telos, and indeed also between energeia and entelekheia. It was present, we saw, from the first lines of Theta 1, presented alongside dunamis and energeia as a sense of being. We find it also, in a sense at the same time normative and teleological, in the Protrepicus. The term serves here to allow the kinetic sense and the ontological sense of energeia to be unified, and at the same time to range the first under the second.”
“If it can play this role, it is thanks to the double sense that it carries: in fact, ergon signifies at the same time the proper function, understood as the act in which the essence is accomplished, and the oeuvre [completed work]. For the remainder of the text goes on precisely to distinguish between two kinds of act: one intransitive, in which nothing else is accomplished but itself, and the other transitive, which produces a being exterior to itself. To illustrate the first, one gives the example of vision, which is the ergon-function of sight, and serves in itself as a telos, an end; for the second, the example of the construction which, resulting in an ergon-work, the house, is only fully [an end] when taken together with the latter. From this we understand that movement can be called energeia: because it indeed has an ergon and a telos, which are not confused with it, but are its work, or that which it produces, and in which, thenceforward, we can say that it is.”
“In fact, ‘the action of building a house resides in the house that is built, and it comes to be and is at the same time as the house’. This affirmation can appear problematic at first glance: one tends spontaneously to distinguish the transitive activity from what it produces, and the being of the house from that of the movement of its construction, since the house only fully is when, precisely, the movement is no longer. We can nonetheless understand this in the light of the analysis of movement in Physics III, and of its characterization as the act common to the mover and the moved: Aristotle already affirmed that the ergon and the telos of the agent and the patient, or of the mover and the moved, reside in one sole and same energeia. In the same way, it seems that the phrase of Theta 8 has no sense unless by the house we understand not the completed house, but the house as object of the movement of construction. We thus understand that the act of construction comes to be at the same time as the house in the process of being constructed, since the two movements (construction/being constructed) are one. The work and the end of transitive activity do not reside in the achieved product, but in the production itself…. The distinction between immanent activity and transitive activity is no longer so great” (pp. 139-140, emphasis in original).
A being that is “in process” can also be an “achieved” being, in varying degrees insofar it also represents an incremental achievement.
“We have seen in effect that act was identical to form as the end and term of in-potentiality, indeed to the form as realized in a matter. If act is anterior to power from the point of view of ousia, this anteriority is not only the logical one of the form-essence and the ousia prote, but also that of substance and ousia malista” (pp. 140-141).
Here we see Aristotle’s strong vindication of immanence and concrete being. Ends — and indeed “perfection” according to a particular kind — are intended to be understood as realizable in form and matter. This is far indeed from the perspective that all finite things necessarily fall infinitely short of a perfection conceived as infinite. For Aristotle, the highest being will be characterized not as infinite, but as pure act and as the good.
