Aristotle: Metaphysics Theta

This paper offers an interpretation of Aristotle’s concepts of dynamis and energeia (commonly translated as potentiality and actuality), and of the thematic progression of Metaphysics IX. I first raise the question of where motion fits in Aristotle’s categories and argue that the locus of motion in the system of categories are the categories of doing and suffering, in which case dynamis and energeia in respect of motion can also be understood as the dynamis and energeia of doing and suffering. Next, (...) I argue that the analogy that Aristotle draws in IX.6 is an analogy between the dynamis and energeia of doing and suffering and the dynamis and energeia of substance. Finally, I try to show that it is this analogy between the kinetic and non-kinetic variants of dynamis and energeia—and not the distinction between end-inclusive and end-exclusive activities—that provides the key to understanding the structure of Metaphysics IX.

This paper clarifies the way Aristotle uses generation to establish the priority of activity in time and in being. It opens by examining the concept of genetic priority. The argument for priority in beinghood has two parts. The first part is a synthetic argument that accomplishment is the primary kind of source, an argument based on the structure of generation. The second part engages three critical objections to the claim that activity could be an accomplishment: activity appears to lack its (...) own structure; activity is different in kind from the object it accomplishes; and activity is external to its accomplishment. Aristotle responds to these objections by analyzing the structure of generation. In the course of the argument, Aristotle establishes that beinghood and form are activity. (shrink)

The belief that Aristotle opposes potency (dunamis) to actuality (energeia or entelecheia) has gone untested. This essay defines and distinguishes forms of the Opposition Hypothesis—the Actualization, Privation, and Modal—examining the texts and arguments adduced to support them. Using Aristotle’s own account of opposition, the texts appear instead to show that potency and actuality are compatible, while arguments for their opposition produce intractable problems. Notably, Aristotle’s refutation of the Megarian Identity Hypothesis applies with equal or greater force to the Opposition Hypothesis. (...) For Aristotle, then, potency and actuality are compatible.

Tun und Können erläutert und diskutiert den Gründungstext der Modalontologie: das neunte Buch der Metaphysik des Aristoteles. Aristoteles' Thesen und Argumente werden zum ersten Mal in Gänze mit formalen analytischen Mitteln rekonstruiert und auf ihre Kohärenz und Gültigkeit geprüft. Erstmals verwendet der Autor dazu eine adverbiale Analyse von Ausdrücken des Könnens und des Vermögens als Prädikatmodifikatoren. Das Buch zeigt, dass Aristoteles' Theorie der Vermögen nicht nur eine konsistente, sondern auch eine leistungsfähige Analyse von Dispositionen und Dispositionsprädikaten bietet. -/- Die Neuausgabe (...) wurde vollständig durchgesehen und um weiterführende Anhänge ergänzt. -/- Der Inhalt: Können, Tun und Möglichkeit. Eine Einführung • Die kausale Dimension von Vermögen • Die ontologische Dimension von Vermögen• Eine notwendige Bedingung für Vermögen • Hindernisse und Verwirklichung • Prioritätsfragen • Aristotle’s Theory of Dispositions • Das Problem des Neuen • Planners, Deciders, Performers.

Of Aristotle’s core terms, potency (dunamis) and actuality (energeia) are among the most important. But when we attempt to understand what they mean, we face the following problem: their primary meaning is movement, as a source (dunamis) or as movement itself (energeia). We therefore have to understand movement in order to understand them. But the structure of movement is itself articulated using these terms: it is the activity of a potential being, as potent. This paper examines this hermeneutic circle, and (...) works out a strategy for reading Aristotle based on his conception of our epistemological predicament. This hermeneutic approach helps us gain access to the phenomena of movement and its sources (potency, and energeia). The paper closes with a review of the conceptual resources we deploy to think about movement: homogeneity, space and time, impulse, relativity, the blend of sameness and difference, and being and non-being. Showing that Aristotle uses none of these clears the landscape for a fresh inquiry into his account of movement. (shrink)

_ Source: _Volume 60, Issue 1, pp 88 - 126 The dominant interpretation of Metaphysics Θ.8 commits Aristotle to the claim that the heavenly bodies’ eternal movements are not the exercises of capacities. Against this, I argue that these movements are the result of necessarily exercised capacities. I clarify what it is for a heavenly body to possess a nature and argue that a body’s nature cannot be a final cause unless the natural body possesses capacities that are exercised for (...) the sake of its nature qua form. This discussion yields a better understanding of what capacities are, what explanatory work capacities do, and what it is to possess a nature. (shrink)

My topic is the fundamental Aristotelian division between the animate and the inanimate. In particular, I discuss the transformation that occurs when an inanimate body comes to be ensouled. When nutriment is transformed into flesh it is first changed into blood. I argue that blood is unique in being, at one and the same time, both animate and inanimate; it is inanimate nutriment in actuality (or in activity) and animate flesh in potentiality (or in capacity). I provide a detailed exposition (...) of these manners of being (covering individual substances, artifacts, and mixtures), apply these insights to the case of blood, and then argue that blood's curious status is central to understanding hylomorphism in living organisms.

The alleged but unclear distinction between so-called “immanent” and so-called “transeunt” causation is structurally similar to an Aristotelian distinction between two kinds of potentiality (dunamis). It is argued that Aristotle’s distinction is in turn grounded in one between a metaphysically basic notion, rooted in his property theory, and a metaphysically posterior notion proper to the understanding of change in the science of nature. By examining Aristotle’s distinction, we can give a satisfying account of immanent and transeunt causation more generally. Furthermore, (...) once we clarify the distinction in this way, some contemporary appeals to immanent causation turn out to be misguided, while others look promising. (shrink)

Review of Aristotle: Metaphysics Theta, translated and annotated by S. Makin.

Mitä oleva on? Omaisuus ja elämä pureutuu tähän filosofian peruskysymykseen seuraten kahta länsimaisen filosofian jättiläistä, Aristotelestä ja Heideggeria. Siinä missä Aristoteles kysyy olevaa substantiivina ja tilana, etsii Heidegger olemisen mieltä verbinä ja tapahtumana. Nämä kaksi merkitystä löytyvät myös suomen olla-verbistä: "omistaa jotakin" ja "olla olemassa, elossa". Omaisuus ja elämä antavat peruslähtökohdat olevan tulkitsemiselle. Kirja vie lukijansa filosofian kreikkalaisille juurille ja sen uusimpiin, Heideggerin avaamiin mahdollisuuksiin.

Com o propósito de analisar a relação entre ser e movimento a partir dos conceitos de ato e potência, elaboramos um mapeamento do livro Θ da Metafísica, capaz de orientar o entendimento de sua estrutura central. Visto como um dos modos de se dizer o ser, o ser em ato e em potência é parte integrante e fundamental da investigação metafísica. A distinção entre ser em ato e em potência pretende resolver o clássico problema do não-ser que vem a ser, (...) mostrando como o não-ser é apenas não-ser ainda em ato, mas já é ser em potência e este guarda as condições para sua necessária atualização. A reconstrução argumentativa de Θ procurou ressaltar três aspectos principais: (1) Ato e potência funcionam como um elemento de conexão entre as outras ciências – práticas, produtivas e teóricas – que são subordinadas à Ciência do Ser enquanto Ser, a Metafísica. (2) Há uma forte relação entre o par conceitual ato/potência e os outros conceitos fundamentais da filosofia aristotélica, tais como: substância, forma, matéria, ação, bem, natureza e fim. Desse modo, ato e potência somente serão plenamente compreendidos se também forem considerados esses outros conceitos. (3) Há uma relação direta entre os dois sentidos em que ato e potência podem ser entendidos - o cinético e o metafísico - e a seguinte divisão interna de Θ: de Θ1 a Θ5 a investigação está centrada sob o ângulo do movimento, é o momento cinético, em que Aristóteles dedica-se mais à análise da potência caracterizada como um princípio de movimento.

Translation of Aristotle’s Metaphysics IX and X (Theta & Iota) into Portuguese, with a few notes, experimental glossary and introduction. The translation, which was made at 2004, is preliminary and its publication was intended to provide a didactic tool for courses as well as a provisional resource in research seminars. It needs some revision. I am currently working (slowly...) on the revision of the translation and a new revised one will surely appear at some point.

In 'Metaphysics IX.6' (1048b 18-35) Aristotle presents a test to distinguish between "kinesis" and "energeia," based on relations between the perfective and the imperfective aspect of the verb. This passage has been interpreted as drawing a linguistic distinction between classes of verbs (e.g., stative verbs) by means of a linguistic criterion (Ackrill, Graham). But such an interpretation is in conflict with the text. Aristotle's test must, therefore, be understood as a metaphysical criterion between items in the world (rather than lingual (...) items) by means of a metaphysical criterion, exploiting properties of these items. These items are events, and 'Metaphysics IX.6' exhibits Aristotle's awareness to certain topics discussed in modern event ontology. (shrink)
