Ackrill’s Problem is a tension between Aristotle’s alleged view that the matter of a living being is a body that is essentially ensouled, and his view that the matter of a substance preexists its generation. Most interpreters solve the tension by claiming that the subject of substantial generation is not the organic body of the living being, but its non-organic matter. I defend a different solution by showing that the embryological theory ofOn the Generation of Animalsimplies that the organic body (...) of a living being already exists before acquiring the soul in actuality.

This paper focuses on the relation between version α of the seventh book of Aristotle’s Physics and the two byzantine families which shape the transmission lineage of most Aristotelian texts. To this end, it establishes a stemma codicum of all known manuscripts of version α. The first step reexamines Simplicius’ testimony in order to overcome the stemmatic problem arising from it: Simplicius’ statement that there was a version β for chapters 4 and 5 seems to be mere speculation on his (...) part. This allows for the more plausible assumption that only the first three chapters of book VII were transmitted in two versions. The paper then deals with the witnesses of version α, which either transmit version α as a whole or a mixture of the two versions. H and I are shown to stem from the same manuscript ι. ι was used by E2, who famously annotated Paris. 1853 and copied in its margins scholia derived from Philoponus’ commentary as well as κεφάλαια of book VII, both of which also feature in manuscripts close to H and I. Though ι is the source of both a version α and a version β, the original version of manuscript ι was βι. Therefore, version α cannot be associated with certainty to either of the two byzantine families of Aristotle’s natural works. Although version α may come from a now extinct third family, there is no trace of such a family in either Paris. 1859 or Vind. 64, which both got the text of book VII from the same manuscript φ. In any case, the evidence points to all direct witnesses of version α coming from only two sources: ι and φ. (shrink)

Este artículo se concentra en la discusión crítica que Pseudo Justino dirigió hacia ciertos principios básicos de la filosofía de la naturaleza de Aristóteles. Pseudo Justino dirige su crítica a la doctrina aristotélica de la eternidad del movimiento, del tiempo y del mundo. También argumenta contra Aristóteles para mostrar la no-eternidad del éter, implicando una unificación de los reinos terrestre y celestial.

Este ensayo se propone presentar una lectura de las críticas de Aristóteles a Parménides en la Física. El autor sugiere que algunas importantes cuestiones que Aristóteles tiene en cuenta cuando determina los principios básicos de la ciencia de la naturaleza surgen de esas críticas. Boeri argumenta que, a pesar del fuerte desacuerdo declarado por Aristóteles en Física I 2-3 respecto de las posiciones eleáticas en general y la posición de Parménides en particular, Aristóteles aprovecha su discusión con Parménides de un (...) modo constructivo a favor de su propia teoría del cambio y, en general, de las condiciones indispensables para la constitución de la ciencia de la naturaleza. Según el autor, uno de los puntos centrales del desacuerdo de Aristóteles con Parménides es al mismo tiempo una de las más fértiles cuestiones desde el punto de vista del uso de Aristóteles de tal desacuerdo para establecer los fundamentos de su física.

In this expansive and highly original two-volume work, Jim Behuniak reformulates John Dewey's late-period "Cultural turn" and proposes that its next logical step is an "intra-Cultural philosophy" that goes beyond what is commonly known as "comparative philosophy." Each volume models itself on this new approach, arguing that early Chinese thought is poised to join forces with Dewey in meeting an urgent cultural need: namely, helping the Western tradition to correct its outdated Greek-medieval assumptions, especially where these result in pre-Darwinian inferences (...) about the world. Relying on the latest findings in Chinese philosophy, these volumes establish "specific philosophical relationships" between Dewey's ideas and early Chinese thought for this purpose, showing how together they can assist us in getting our thinking "back in gear" with the world as it is currently known through the biological, physical, and cognitive sciences. Volume One: Dao and Nature engages Dewey with themes generally associated with "Daoism," and includes discussion of the organization of organic form, teleology, cosmology, knowledge, the body, and technology. Volume One thus works to establish "Chinese natural philosophy" as an empirical framework in which to consider the cultural-level phenomena examined in Volume Two: Dao and Culture. (shrink)

El estudio del tiempo en Physica IV.10-14 presenta grandes dificultades, una de ellas es el vínculo entre tiempo y alma realizada en 223a21-28. Este pasaje fue discutido por varios especialistas modernos durante el siglo XX. Si bien no hay consenso unánime, la “interpretación realista” estuvo muy extendida durante el siglo pasado. En este trabajo me propongo discutir un pasaje de la premisa 223a25-26 en el argumento de Aristóteles respecto de este vínculo. En primer lugar, rechazo la “interpretación realista” según la (...) cual el tiempo como número puede existir independientemente del alma. Luego, muestro que la numerabilidad del tiempo impide su independencia respecto del alma, a diferencia de lo que ocurre con ‘lo sensible’. (shrink)

This paper presents Aristotle’s method of understanding the first principles of natural things in the Physics I.1 and analyzes the three stages of which this method consists. In the Physics I.1, Aristotle suggests that the natural proper route which one has to follow in order to find out the first principles of natural things is to proceed from what is clearer and more knowable to us to what is more knowable and clear by nature. In the Physics I.1, the terms (...) καθόλου and καθ΄ ἕκαστα are not used in their usual meaning. This paper examines the Physics I.1 in comparison with the Posterior Analytics II. 19 in order to elucidate the meaning of καθόλου in the first chapter of Aristotle’s Physics. Furthermore, it reaches the conclusion that the structure of the natural world to which we belong determines the structure and the form of our knowledge. On the one hand, natural things are composite and, on the other hand, perception is involved in the initial grasping of natural things as composites. Thus, since perceptual knowledge is more accessible to us than any other kind of knowledge it is natural to reach knowledge of simple things, i.e., of the principles, starting our inquiry with the composites.

Dans cet article, l'auteur fait état de nouvelles données à propos de trois traités attribués a Alexandre d'Aphrodise en arabe et dont on pensait qu'ils n'avaient pas de correspondant grec. II montre que le premier (D.8a) est une version adaptée – selon les normes du “cercle d'al-Kindi’ – deQuaestioI 21, à côte de la traduction plus tardive et plus exacte de cette mêmeQuaestiodue à Abù ‘Uṭmān al-Dimašqī (m. 900). II montre que les deux autres traités (D.9 et D.16), en revanche, (...) ne sont pas d'Alexandre d'Aphrodise, mais qu'il s'agit de versions adaptées – toujours selon les normes du “cercle d'al-Kindi” – de passages duDe Aeternitate mundi contra Proclumde Jean Philopon, empruntés respectivement à IV, 4–6 et IX, 11. On savait que cet ouvrage fut traduit en arabe. Mais, hormis quelques courts fragments dans al-Bīrūnī (m. 1048), c'est, semble-t-il, la première fois que l'on en met au jour des extraits adaptés de cette importance. Des jalons sont posés en vue de répondre à la question de la situation historique de l'epitomateur. Dans l'Appendice II, un autre traité attribué à Alexandre (D.27g) apparaît – provisoirement – comme un texte composite mêlant des éléments issus de Philopon et d'autres issus des textes néoplatoniciens en arabe. Enfin dans l'Appendice III, sont situées la manière dont Miskawayh (m. 1030) utilise D.16, et celle dont ‘Abdallaṭīf al-Baġdādī (m. 1231) utilise D.27g. (shrink)

I discuss the argument Aristotle ascribes to Parmenides at Physics 186a23-32. I discuss (i) the reasons why Aristotle considers it as eristic and inconclusive and (i) the solution (lusis) Aristotle proposes against it.

I discuss the exact meaning of the thesis according to which the object of scientific knowledge is necessary. The thesis is expressed by Aristotle in the Posterior Analytics, in his definition of scientific knowledge. The traditional interpretation understands this definition as depending on two parallel and independent requirements, the causality requirement and the necessity requirement. Against this interpretation, I try to show, through the examination of several passages that refer to the definition of scientific knowledge, that the necessity requirement specifies (...) more exactly the causality requirement: what cannot be otherwise is the explanatory relation between the explanandum and the cause by which it is what it is.

The pseudo-Platonic Definitions seems to ascribe to ὄνοµα, ‘name’, the function of signifying two kinds of predicate. This is problematic, and I propose an emendation of the text, arguing that a definition of ῥῆµα, ‘verb’, has fallen out.

Having in mind the concept of poiesis, as Paul Valéry uses it, time and movement are presented as concepts produced within the project of understanding the natural world. From the idea of philosophy as a way of constructing through concepts the intelligibility of phenomena, I will show the coherence between the construction of the concept of time and that of the concept of movement.

This book investigates Aristotle’s views on abstraction and explores how he uses it. In this work, the author follows Aristotle in focusing on the scientific detail first and then approaches the metaphysical claims, and so creates a reconstructed theory that explains many puzzles of Aristotle’s thought. Understanding the details of his theory of relations and abstraction further illuminates his theory of universals. Some of the features of Aristotle’s theory of abstraction developed in this book include: abstraction is a relation; perception (...) and knowledge are types of abstraction; the objects generated by abstractions are relata which can serve as subjects in their own right, whereupon they can appear as items in other categories. The author goes on to look at how Aristotle distinguishes the concrete from the abstract paronym, how induction is a type of abstraction which typically moves from the perceived individuals to universals and how Aristotle’s metaphysical vocabulary is "relational.’ Beyond those features, this work also looks at how of universals, accidents, forms, causes and potentialities have being only as abstract aspects of individual substances. An individual substance is identical to its essence; the essence has universal features but is the singularity making the individual substance what it is. These theories are expounded within this book. One main attraction in working out the details of Aristotle’s views on abstraction lies in understanding his metaphysics of universals as abstract objects. This work reclaims past ground as the main philosophical tradition of abstraction has been ignored in recent times. It gives a modern version of the medieval doctrine of the threefold distinction of essence, made famous by the Islamic philosopher, Avicenna. (shrink)

I argue that these inconsistencies in wording and practice reflect the existence of two distinct Aristotelian views of inquiry, one peculiar to the Posterior Analytics and the other put forward in the Physics and practiced in the Physics and in other treatises. Although the two views overlap to some degree (e.g. both regard a rudimentary understanding of the subject as an essential first stage), the view of the syllogism as the workhorse of scientific investigation and the related view of inquiry (...) as a search for the ‘missing middle terms’ turn out to be ideas peculiar to the Analytics. Conversely, the techniques of analysis and differentiation highlighted in the Physics account receive only cursory attention in the Analytics. However, when we consider the character of Aristotle’s own inquiries, on both scientific and philosophical topics, it becomes clear that it is the Physics rather than the Posterior Analytics that gives us Aristotle’s considered view the path to knowledge.

There is a debate about whether particular properties are for Aristotle non-recurrent and trope-like individuals or recurrent universals. I argue that Physics I.7 provides evidence that he took non-substantial particulars to be neither; they are instead non-recurrent modes. Physics I.7 also helps show why this matters. Particular properties must be individual modes in order for Aristotle to preserve three key philosophical commitments: that objects of ordinary experience are primary substances, that primary substances undergo genuine change, and that primary substances are (...) ontologically fundamental.

ArgumentThe aim of this paper is two-fold: to offer an interpretation that preserves the natural reading ofPhysicsII 1 – that Aristotle is drawing a stark distinction between what is natural and what is artificial; and to show how there is logical room for atertium quid– a category for things that are products of both nature and art. This aim is attained by highlighting two important qualifications Aristotle makes about the products of art in relation to an innate internal principle of (...) change and pointing out that the proper understanding of the significance of the essential-accidental distinction that Aristotle draws must be viewed in the context where he identifies two kinds of nature – form and matter. Based on these analyses, the following three logical categories are shown to be consistent with the passage: 1) purely natural things; 2) essentially artificial objects; and 3) essentially natural things with artificial aspects.

People currently regard justice as the main principle of institutions and society, while in ancient Greek people took it as the virtue of citizens. This article analyzes Aristotle’s virtue of justice in his method of virtue ethics, discussing the nature of virtue, how justice is the virtue of citizens, what kind of virtue the justice of citizens is, and the prospect of the virtue of justice against a background of institutional justice. Since virtue can be said to be a specific (...) individual character, Aristotle also defines the virtue of justice as the character of justice, with which citizens act justly and desire to do what is just. The virtue of justice is also an individual ethical virtue, differing from others for it is at the same time a social ethic. We can call the virtue of justice a “non-individual individual ethical virtue.” It has been explained as between pure altruism and egoism, which is a wrong explanation. John Rawls regards justice as the first virtue of social institutions, challenging Aristotle’s virtue of justice, an assertion which also needs further deliberation. (shrink)

We provide a new interpretation of Zeno’s Paradox of Measure that begins by giving a substantive account, drawn from Aristotle’s text, of the fact that points lack magnitude. The main elements of this account are (1) the Axiom of Archimedes which states that there are no infinitesimal magnitudes, and (2) the principle that all assignments of magnitude, or lack thereof, must be grounded in the magnitude of line segments, the primary objects to which the notion of linear magnitude applies. Armed (...) with this account, we are ineluctably driven to introduce a highly constructive notion of (outer) measure based exclusively on the total magnitude of potentially infinite collections of line segments. The Paradox of Measure then consists in the proof that every finite or potentially infinite collection of points lacks magnitude with respect to this notion of measure. We observe that the Paradox of Measure, thus understood, troubled analysts into the 1880’s, despite their knowledge that the linear continuum is uncountable. The Paradox was ultimately resolved by Borel in his thesis of 1893, as a corollary to his celebrated result that every countable open cover of a closed line segment has a finite sub-cover, a result he later called the “First Fundamental Theorem of Measure Theory.” This achievement of Borel has not been sufficiently appreciated. We conclude with a metamathematical analysis of the resolution of the paradox made possible by recent results in reverse mathematics. (shrink)

In Metaphysics A 6, Aristotle claims that Plato only recognises formal and material causes. Yet, in various dialogues, Plato seems to use and distinguish efficient and final causes too. Consequently, Harold Cherniss accuses Aristotle of being an unfair, forgetful, or careless reader of Plato. Since then, scholars have tried to defend Aristotle’s exegetical skills. I offer textual evidence and arguments to show that their efforts still fall short of the desired goal. I argue, instead, that we can reject Cherniss’ assertation (...) by re-examining Aristotle’s exegetical and methodological assumptions. (shrink)

Este ensayo se centra en un breve pero significativo pasaje de Física, IV 13, 222a28-b7, en el que Aristóteles provee dos argumentos a favor de la infinitud extensiva del tiempo. El primero, argumenta Vigo, presenta su infinitud extensiva como dependiente de la infinitud del movimiento. El segundo argumento, en cambio, procede inmanentemente a partir de la consideración de las propiedades que el ‘ahora’ posee como límite que da cuenta tanto de la posibilidad de la delimitación como de la continuidad del (...) tiempo. El artículo también examina algunas consecuencias sistemáticas de este último argumento e intenta aclarar algunos acertijos que involucra desde el punto de vista metodológico. Tales dificultades subrayan algunos límites estructurales del intento de Aristóteles por llevar a cabo un tratamiento reductivo de las propiedades del tiempo consideradas como un modo del continuum dependiente de otros dos dominios más básicos: el movimiento y la magnitud espacialmente extensa.

In Metaphysics Γ, Aristotle argues against those who seem to accept contradictions. He distinguishes between the Sophists, who deny the principle of non-contradiction through arguments, and the Natural Philosophers, whose physical investigations lead to the acceptance of objective contradictions. Heraclitus’ name appears throughout the discussion. Usually, he is associated with the discussion against the Sophists. In this paper, I explore how the discussion with the Natural Philosophers may illuminate both the interpretation of Heraclitus by Aristotle and Heraclitus’ own worldview. To (...) refute the Natural Philosophers, Aristotle proposes a general reconstruction of their reasoning. Roughly, relying on sensory evidence (A1), they see that the same thing changes from one opposite to another (A2). Such a change appears to characterize a generation out of non-being, which a Natural Philosopher does not accept (A3). To solve the problem, despite their different worldviews, Natural Philosophers hint at a state in which opposites co-occur, characterizing an objective contradiction (C). Looking at the discussion in Metaphysics Γ and Heraclitus fragments, sections 1–3 show how assumptions A1, A2, and A3 easily apply to Heraclitus. The case of the conclusion is more challenging. In the case of the Pluralists, the co-existence of opposites characterizes a state in which there is no generation. Such a view does not fit Heraclitus’ mobilism. To argue that Aristotle’s argument is general enough to encompass dynamic views, I examine his problematization of accepting the change of change in Metaphysics K and Physics V. There, after re-stating several points that appear in Metaphysics Γ, Aristotle argues that accepting the becoming of another becoming leads to a state of contradiction in which the becoming is perishing. Heraclitus’ B8, cited in Nicomachean Ethics, gives evidence that, for Aristotle, Heraclitus puts a process at the origin of an opposite process. Moreover, after examining the expression ‘living the death/dying the life’ in B62, I argue that Heraclitus was aware that his worldview implied a dynamic objective contradiction. Finally, an analysis of elemental changes in B36 proves that accepting objective contradictions does not make Heraclitus’ worldview less attractive. (shrink)

G. H. von Wright proposed that a temporal interval exemplifies a real contradiction if at least one part of any division of this interval involves the presence of contradictorily related (though non-simultaneous) states. In connection with intervals, two negations must be discerned: 'does not hold at an interval' and 'fails throughout an interval'. Von Wright did not distinguish the two. As a consequence, he made a mistake in indicating how to use his logical symbolism to express the notion of real (...) contradiction. The present paper aims to reconstruct and philosophically motivate von Wright's argument for the possibility of real contradictions. (shrink)

The model of a closed linear measure space, which can be used to model Aristotle’s treatment of motion (kinesis), can be analogically extended to the qualitative ‘spaces’ implied by his theory of contraries in Physics I and in Metaphysics Iota, and to the dimensionless ‘space’ of the unity of matter and form discussed in book Eta of the Metaphysics. By examining Aristotle’s remarks on contraries, the subject of change, continuity, and the unity of matter and form, Aristotle’s thoughts on motion, (...) on contraries, and on the unity of substance can be brought together under a single interpretive framework, which can provide an approach to interpreting his ontology.

The endeavour of science is to find unity in multitude, relatedness in diversity, continuity in discontinuity. By this way reality is simplified for scientific conception and description. With its reliance on observational data and logic, and with the scientific approach to understand the complexity, functionality, rationality and interrelationship of every aspect of reality, natural sciences do bring forward fascinating new insights on the concealed secrets in natural structures and processes. The crucial position of time in the laws of the universe (...) followed from the work of Newton in the late seventeenth century. Newton gave time an abstract existence, independent from nature. Einstein restored time to its place in the heart of nature, as an integral part of the physical world. From the implications of Einstein’s time, scientists made one of the most important discoveries in the history of human thought: that time, and hence all of physical reality, must have had a definite origin in the past. Thus natural sciences have to accept the concept of origin. God formed man to glorify him as his earthly steward by giving him dominion over creation. Man is therefore responsible to God, also in his formation of science, by which a miraculous world of boundless diversity and interrelationship from the atomic scale to astronomical vastness is revealed. If we also take account of the transcendental revealed principle of creation, scientific thought becomes open, also in our ethical responsibility. (shrink)

La filosofía de las matemáticas de Aristóteles es una investigación acerca de tres asuntos diferentes pero complementarios: el lugar epistemológico de las matemáticas en el organigrama de las ciencias teoréticas o especulativas; el estudio del método usado por el matemático para elaborar sus doctrinas, sobre todo la geometría y la aritmética; y la averiguación del estatuto ontológico de las entidades matemáticas.

En el presente trabajo nos interesa analizar cómo Aristóteles formula los principios de la física a partir de la noción de generación. Nuestra tesis es que Física I 7 es el “momento” de euporía que cierra un proceso que se inicia en 1-2 con la problematización acerca de la naturaleza y número de los principios. Para demostrar esto, dividiremos el trabajo en dos partes. En la primera intentaremos establecer por qué Aristóteles emprende esta investigación y cuál es el contexto argumentativo (...) a partir del cual postula sus principios. En la segunda parte, analizaremos los supuestos con base en los cuales sostiene que materia, forma y privación son los tres principios buscados. (shrink)

Aristotle's thesis in "Physics" I 8 is that a certain old and familiar problem about coming to be can only be solved with the help of the new account of the "principles" he has developed in "Physics" I 7. This is a strong thesis and the literature on the chapter does not quite do it justice; specifically, as things now stand we are left wondering why Aristotle should have found this problem so compelling in the first place. In this paper (...) I develop an interpretation which (I hope) will help to remedy this. I believe that Aristotle's problem about coming to be depends on a certain principle to the effect that "nothing can become what it already is" (it is this that is supposed to explain why τὸ ὄν cannot come to be ἐξ ὄντος -- cf. 191a30). The main innovation of the interpretation developed here is its suggestion that we understand this principle as a principle about kinds. So understood, the principle does not make the comparatively trivial point that nothing can become any individual it already is, but rather the more powerful and substantive point that nothing can become any kind of thing it already is. I argue that this is a point which Aristotle himself accepts and that this is why the problem about coming to be raises serious difficulties for him. I also discuss Aristotle's proposed solutions to this problem, explaining how each draws on his new account of the principles and why each is required for any full resolution of the difficulties the problem raises. In this way I hope to show how the interpretation developed here does justice to the very strong thesis with which Aristotle begins "Physics" I 8. I conclude briefly and somewhat speculatively with a suggestion as to why Aristotle might accept the principle on which I have suggested the problem turns. (shrink)

While Aristotle provides the crucial testimonies for the paradoxes of motion, topos, and the falling millet seed, surprisingly he shows almost no interest in the paradoxes of plurality. For Plato, by contrast, the plurality paradoxes seem to be the central paradoxes of Zeno and Simplicius is our primary source for those. This paper investigates why the plurality paradoxes are not examined by Aristotle and argues that a close look at the context in which Aristotle discusses Zeno holds the answer to (...) this question.

On Zeno Beach there are infinitely many grains of sand, each half the size of the last. Supposing Aristotle denied the possibility of Zeno Beach, did he have a good argument for the denial?

It is attempted to show that none of these arguments (...) was Aristotle’s. Indeed, perhaps Aristotle’s finitism applied to magnitude only, not plurality. (shrink)

Este ensayo intenta ofrecer una reconstrucción de los argumentos de Aristóteles del uso de explicaciones teleológicas en Física II 8.

Robert Wardy's recent The Chain of Change has again brought to the fore the question of the role of Physics VII in the development of Aristotle's conception of motion.

He also claims that this account is the only one that can save us from a version of self-motion made unacceptable by Aristotle's (...) hylomorphic account developed elsewhere. This is what Wardy thinks enables him to infer that the account of motion in Physics VII leads directly into the argument about unmoved movers in Physics VIII. I want first to show why I think that Wardy's thesis about the conceptual links between VII and VIII need not hold. This disconnection of VII from its current context, taken together with the thesis of W. D.

I argue that Aristotle’s arguments in passages regarding chance in the Physics and in passages about ignorance in action in the Nicomachean and Eudemian Ethics presuppose two different uses of ‘for the sake of something’, which are able to explain respectively the wish or thought of agents and the type or nature of what they actually do. In my view, however, this does not commit Aristotle, in the ‘ignorance’ passages from the two Ethics, to holding that the type or nature (...) of what the agents actually do is for the sake of killing or wounding.

In 'Physics' I.7, Aristotle claims that plants and animals are generated from sperma. Since most understood sperma to be an ovum, this claim threatens to undermine the standard view that, for Aristotle, the matter natural beings are generated from persists through their generation. By focusing on Aristotle’s discussion of sperma in the first book of the 'Generation of Animals', I show that, for Aristotle, sperma in the female is surplus blood collected in the uterus and not an ovum. I subsequently (...) argue that, for Aristotle, this blood does persist through the production of the fetus. (shrink)

In Physics I.8, Aristotle outlines and responds to an Eleatic argument against the reality of change. I defend a new reading according to which the argu- ment assumes Predicational Monism, the claim that each being can possess only one property. In Phys. I.2, Aristotle responds to Predicational Monism, which he attributes to the Eleatics; I argue that he uses this response to distinguish coin- cidental from non-coincidental becoming, a distinction he employs in Phys I.8 to resolve the argument against the (...) reality of change. The Eleatics’ acceptance of Predicational Monism, I argue, explains why this distinction is unavailable to them. (shrink)

It is commonly held that Theophrastus criticized or rejected Aristotle's account of place. The evidence that scholars put forward for this view, from Simplicius' commentary on Aristotle's Physics, comes in two parts: (1) Simplicius reports some aporiai that Theophrastus found for Aristotle's account; (2) Simplicius cites a passage of Theophrastus which is said to 'bear witness' to the theory of place which Simplicius himself adopts (that of his teacher Damascius) — a theory which is utterly different from Aristotle's. But the (...) aporiai have relatively straightforward solutions, and we have no reason to suppose that Theophrastus didn't avail himself of them (and some reason to think that he did). Moreover, the text which Simplicius cites as bearing witness to Damascius' view on closer inspection does not seem to be inconsistent with Aristotle's account of place or natural motion. (shrink)

In this paper I argue that Proclus’ criticism of the causality of Aristotle’s intellect is part of a general attack on Aristotle’s metaphysics. I show how Proclus criticises Aristotle for rejecting the One as a metaphysical principle and the metaphysical confusion that arises from this. Additionally, I claim that for Proclus Aristotle’s understanding of efficient causality differs from Plato’s and I discuss two of his arguments that Aristotle should have accepted the intellect as an efficient cause. As I show throughout, (...) Proclus differs in his approach to Aristotle from the harmonising agenda of Ammonius and Simplicius. (shrink)

In Physics VI.9 Aristotle addresses Zeno's four paradoxes of motion and amongst them the arrow paradox. In his brief remarks on the paradox, Aristotle suggests what he takes to be a solution to the paradox.In two famous papers, both called 'A note on Zeno's arrow', Gregory Vlastos and Jonathan Lear each suggest an interpretation of Aristotle's proposed solution to the arrow paradox. In this paper, I argue that these two interpretations are unsatisfactory, and suggest an alternative interpretation. In particular, I (...) claim that what seems on the face of it to be Aristotle's solution to the paradox raises two puzzles to which my interpretation, as opposed to Lear's and Vlastos's, provides an adequate response.

I argue for a new construal of Aristotle’s definition of anagnorisis (recognition) in Poetics 11. Virtually all translators and interpreters of the definition have understood the phrase ton pros eutuchian e dustuchian horismenon as a subjective genitive characterizing the persons involved in the recognition. I argue that it should instead be taken as a partitive genitive characterizing the genus of changes (metabolon) of which recognitions are a species. In addition to being preferable on philogical grounds, the construal I recommend helps (...) illuminate the relation between recognition and reversal (peripeteia) and makes sense of Aristotle’s views about the relative values of various kinds of recognition.
