Aristotle notoriously begins his examination of being in the sense ofdunamisandenergeiainMetaphysicsTheta with what he describes as the sense that is ‘most dominant’ but not useful for his present aim. He proceeds to define the not-useful sense ofdunamisas “the principle of change in something else or in itself qua other”, along with other senses derived from this primary sense. But what then is the useful sense? All that Aristotle tells us at the outset is that it is a sense that extends (...) “beyond things spoken of only in relation to motion” and nowhere in Book Theta does he explicitly identify the useful sense as such. This has allowed for very different interpretations of the useful sense in the literature, the primary ones being that it is (1) ‘possibility’, (2) the potential to receive a form, (3) being-potentially-x understood modally as encompassing all specific senses ofdunamis, and (4) capacity for substantial change. The present paper argues that there are significant problems with all of these suggestions and defends an identification of the useful sense ofdunamiswith the sense that Aristotle explicitly opposes to the not-useful sense at the start of Theta 8:phusis(‘nature’). This goes hand-in-hand with an identification of the useful sense ofenergeiawith ‘activity’ as distinguished from motion/change at the end of Theta 6. What makes these senses ofdunamisandenergeiathe useful ones for Aristotle’s present aim is that they are required to explain fully the priority ofenergeiatodunamisin substance defended in Theta 8, they support the identification in Theta 9 ofenergeiawith the good, and they explain the unity of the only substances that Aristotle recognizes as being genuinely substances: natural living substances.

The important conceptual innovation of Metaphysics 9 is not in an extension of dunamis into the ontological realm, but in establishing energeia as the primary sense of the unit of being. The career of dunamis moves from principles of contrariety requiring a hypokeimenon ; through its role in the concept of natural motion ; to different roles for active and passive ; to correlations of capacity/fulfillment with body/soul, matter/form, and inner/outer potentialities. These developments lay bases for conceiving (...) the reality of natural beings as enactments, undergirded with the potentials of their constitutional fulfillments, and opens the way in Metaphysics 12 to understanding a being of pure enactment without dunamis.

Modalities enter into practically every area of contemporary philosophy. Great progress has been made in understanding the variety of differences between what is possible, what is actual, and what is necessary. But things were not always so clear. We owe a great debt in this area, as in so many others, to Aristotle, who had a lot to say on the topic, part of which comprises his discussion and use of the actuality/potentiality distinction. One important task in understanding his discussion (...) of actuality and potentiality is locating the distinction within the wider area of modality in general. One very general area in which modalities are significant is the assessment of arguments. Aristotle provides us with the basics of a modal logic, and in Metaphysics V 12, treats the family of modal notions expressed by the Greek noun dunamis and its cognates. This article explores his account of energeia and dunamis, matter and substance, capacities, natures, and dispositions. (shrink)

Since management is about influencing - influencing people who work in the organization, the structure and practices of the organization, as well as its environment - how ‘influencing’ is understood evidently makes a huge difference. The still popular empiricist concept of cause-effect relations as presupposing regularities is mistaken, since it forms no sufficient basis for action in new and unique situations. As alternative notions of causation, the paper discusses the Critical Realist conception of causal powers and the counterfactual conditional view, (...) arguing that the classical notion of power (dunamis in Greek; power, potentiality, possibility, ability, capacity, capability in English) offers the most fruitful analysis of causal relations for managerial purposes. The paper presents the four ontological features of power scrutinised already by Aristotle in his Metaphysics and Physics, and actively discussed in current philosophy of science. These are the potentiality-actuality distinction, full power as consisting of an active and a receptive component, the distinction of rational and non-rational powers, and the idea of hierarchy of powers. These ontological distinctions suit management contexts not only because they allow room for new unique decision-making situations, but primarily because they imply invaluable practical advice. The relevance of the power ontology for management is illustrated in the context of the Bohm and the new Timeout dialogue. The paper concludes with a summary of the practical implications of the classical power ontology to management and the adoption of dialogical practices to managerial expertise. (shrink)

The term dunamis, by which Aristotle defines rhetoric in the first chapter of The Art of Rhetoric, is a "power" term, as its various meanings in Aristotle's corpus—from vernacular ones like "political influence" to strictly philosophical ones like "potentiality"—attest.1 In the Rhetoric, however, dunamis is usually translated as "ability" or "faculty," a designation that, compared to other terms that describe persuasion in ancient Greek poetics and rhetoric (such as "bia" ["force"] or "eros" ["seduction"]), marks rhetoric as a neutral (...) human capacity rather than the use of language entangled in the vagaries of violence and desire.2 John Kirby calls Aristotle's definition "one of the boldest moves in the history of ..

This essay aims to analyze the structure of Aristotle's Metaphysics Θ by explicating various senses of the term δύναµις at issue in the treatise. It is argued that Aristotle's central innovation, the sense of δύναµις most useful to his project in the treatise, is the kind of capacity characteristic of the pre-existent matter for substance. It is neither potentiality as a mode of being, as recent studies maintain, nor capacity for `complete' activity. It is argued further that, in (...) starting with the κύριος sense of δύναµις as capacity for change, Aristotle begins with the most familiar and acknowledged kind of capacity, in order to move to the less familiar but ultimately more useful notion of capacity for substance, and to bring these two kinds together through an analogical relation.

The author presents the Aristotelian conception of capacity/potentiality (dunamis) – one of the most important in Aristotle’s metaphysics. A closer inspection allows to draw conclusion, that the concept of capacity is an important link between ‘theory’ and ‘practice’ (metaphysics on the one side, and practical – ethical, rhetorical, political – skills, on the other). A picture of the connection between theory and practice is based on the most important parts of Metaphysics (books delta and theta), it relates (...) metaphysical definitions to an essential element of Aristotelian practical philosophy – the concept of virtue (aretê). In the practical works of Aristotle, we can find different definitions of aretê: in Nicomachean Ethics Aristotle defines aretê using the notion of disposition (hexis), but in Rhetoric he formulates a definition based on the concept of capacity. Distinctive analysis of this inconsistency shows the significance of capacity in The Stagirite’s philosophy. (shrink)

While virtual simulations are a familiar professional training tool, they have only recently been implemented in teacher education programs. These simulations are used to complement traditional student teacher placement. In this paper, the author critically examines one teacher training simulation, TeachLivE, specifically in terms of its implicit conceptions of what it means to teach and to learn. The analysis utilizes Aristotle’s explanation of the Greek concepts energeia and dunamis, as well as Heidegger’s interpretation of Aristotle’s Metaphysics. The author argues (...) that TeachLivE’s structure implies an ontology of teaching and learning that precludes the cultivation of a teacherly disposition, and that, were this ontology to be corrected, teacher training simulations would be rendered superfluous.

Doing and Being confronts the problem of how to understand two central concepts of Aristotle's philosophy: energeia and dunamis. While these terms seem ambiguous between actuality/potentiality and activity/capacity, Aristotle did not intend them to be so. Through a careful and detailed reading of Metaphysics Theta, Beere argues that we can solve the problem by rejecting both "actuality" and "activity" as translations of energeia, and by working out an analogical conception of energeia. This approach enables Beere to discern a (...) hitherto unnoticed connection between Plato's Sophist and Aristotle's Metaphysics Theta, and to give satisfying interpretations of the major claims that Aristotle makes in Metaphysics Theta, the claim that energeia is prior in being to capacity and the claim that any eternal principle must be perfectly good.

Machines are often employed in Heidegger’s philosophy as instances to illustrate specific features of modern technology. But what is it about machines that allows them to fulfill this role? This essay argues there is a unique ontological force to the machine that can be understood when looking at distinctions between techne and mechane in ancient Greek sources and applying these distinctions to a reading of Heidegger’s early thought on equipment and later thought on poiesis. Especially with respect to Heidegger’s appropriation (...) of Aristotle’s conception of dunamis, it becomes apparent from a Heideggerian perspective that machines provide an increase in capacity to its human users, but only so at a cost. This cost involves a problem of knowledge where the set of operations required in machine use results in the loss of understanding our dependency on being. The essay then concludes with a discussion of how this relation to machinic capacity is not merely pessimistic and deterministic, but indicates what might constitute a free relation to machines.

The account of knowledge in Plato’s Theaetetus, as true belief meta logou, seems to lead to a regress, which may be avoided by defining one kind of knowledge as true belief that rests on a different kind of knowledge. I explore a specific version of this move: to define knowledge as true belief that results from a successful and proper exercise of a rational capacity (a dunamis meta logou).

As part of a more general project which consists in identifying the process by which the modern ontology of power and action came to replace the Aristotelian ontology of in-potency and act, this article questions some fundamental features of Aquinas’ use and reworking of the Aristotelian concepts of dunamis and energeia. First, I ask, how Aquinas can characterise God as being pure act and omnipotent at the same time given that for Aristotle pure act radically excludes all potency. It (...) appears that the Thomistic act not only admits potency-as-power, but also signifies the full power of being so that we can detect in Aquinas the conjunction in the first being - of power with being itself Second, I show how the symmetrical reinterpretation of the Aristotelian concept of in-potency comes to be modified by means of the concept - inherited from Neo-Platonism - of epitedeiotes. Thus understood as receptive capacity, in-potency no longer signifies the principle within each substance of its own proper and immanent act but rather its dependence on the first act, the primary being. In the end, the concept of potency is redistributed by Aquinas between the Creator’s full power of being, and the creature’s mere capacity for being. (shrink)

What I will argue here is that the ethical potentiality of the human being that Aristotle cites in the Nicomachean Ethics refers to the general, rational capacity for someone to appropriate and develop their own specific, natural capacities which make them human; the name of this ability is called virtue, which, when expressed in actions, we call good. To separate out the concepts at work here demands an exegesis of the two kinds of dunamis in Metaphysics Theta, that (...) is, dunamis as causal power of change and dunamis as a potential way of being for an existent capacity. Once we grasp this, we can clarify the nature of virtue as the active, complete state of a capacity in human being which defines their function even though it must be acquired, and it need not ever be actualized. The concepts of habit ( ethos) and practical judgment ( phronesis) give Aristotle the means to solve the problem of how such a potentiality is acquired and how it is actualized, and hence we will end with a discussion of them.

What, for Galen, are powers, and how are they to be properly individuated? The notion of a power or capacity does a great deal of work in Galen. As in Aristotle, the concept of a dunamis is tightly linked with that of an energeia, but these are not simply logical abstractions. Rather the natural energeiai are the basic functional activities of the animal body and its parts, and just as health consists in proper functioning, so disease is defined (...) as ‘damage to one of the natural energeiai of the body’, and these activities are damaged when something interferes with its related dunamis. Here I try to make sense of the apparently very different things Galen says regarding dunameis. For example, he says that they do not inhabit our bodies as we do our houses; that is, presumably, they are not substantial or hypostasized; rather they are properties of us. Equally, he is perfectly clear that they are relational items: a power is a power for affecting something determinate in some determinate way. They. (shrink)

Abstract:The author considers the Eleatic Stranger's account of being as communing (κοινωνεῖν), an under-recognized aspect of the well-known "dunamis proposal" and Plato's unfolding of the notion of being in the Sophist. The Stranger calls being "the power to act upon or be affected" (247d7-e3), and shortly thereafter describes "being affected or acting upon from a certain power" (248b6) as "communing" (248b2). This marks a shift away from understanding being as capacity toward understanding it as activity. The author identifies (...) two functions of the "being-as-communion" account: (1) a critical response to the previous competing quantitative and qualitative ontologies, and (2) a new ontological notion that plays a key role in the great kinds discussion and what follows, capturing the sense in which to be is to engage actively in relations with structuring, causal kinds. He conclude by speaking to the account's valuable insight into the meaning of being as being-with and being-through. (shrink)

L’opération qui définit une puissance est, pour Platon comme pour Aristote, son acte ou sa fin. Platon soutient qu’une puissance ne possède qu’une seule opération propre (conception monovalente de la puissance). Si Aristote souscrit à cette thèse, en y ajoutant quelques précisions destinées à permettre de bien définir les puissances, il semble compliquer la question en introduisant la notion de puissance des contraires qu’il élabore au chapitre 2 du livre Θ de la Métaphysique. Cependant la puissance des contraires ne doit (...) être définie elle-même qu’en fonction de ce qui est son objet en soi, et non par accident ; en outre, on se demandera s’il est certain que la notion de puissance « accompagnée de raison », qui est au fondement de la puissance des contraires, permette vraiment à Aristote de dépasser la conception monovalente de la puissance : le logos montre-t-il bien à lui seul sa privation?
