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)

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)

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)

Zeno’s arrow does not move “in the now” (Phys. VI 8, 239b2) or, equivalently, “in the place it is” (DK 29 B 4). Zeno concludes from this that the arrow does not move at all. In Aristotle (ibid. 9, 239b5–9, 31–33), Zeno’s argument takes the form of an invalid inference from instants to periods of time. Insofar as it fails to bring out an inconsistency in Aristotle’s account of motion, the paradox is thus eliminated. That instantaneous motion is a contradiction (...) in terms belongs to the common ground Aristotle shares with Zeno. That’s why information concerning Zeno’s relevant argument must be sought elsewhere (see section 3). Aristotle’s discussion of the Arrow pertains to the conclusions drawn from the denial of instantaneous motion. But the argument he refutes is of his own making, or so I will argue (section 2). In particular, Aristotle fails to address the presentist commitment adumbrated in his account, which would leave nothing beyond the denial of instantaneous motion for Zeno to prove. Presentism is no option in Phys. VI where a tenseless account of time and motion is offered. I will argue that Aristotle’s account of the tenses in De interpretatione is prone to Zeno’s argument if the present is conceived as an instant – which it arguably is not (section 4). (shrink)

In his theory of time Aristotle does not often mention the present time and nowhere gives a detailed account of it. Nonetheless, present time plays an important role in his conception. I primarily argue for the following claims: (1) According to Aristotle there is a perception of motion and there is a perception of time. These combined perceptions can neither occur in the past nor in the future nor in an indivisible now. Thus, there must be a present time. (2) (...) Aristotle acknowledges the passage of time. This passage of time can only be understood as a passing present. And since an indivisible now cannot pass, the passage of time delivers a further argument for the basic assumption of a present time. – For the most part I simply follow Aristotle’s argument in Physics IV 10 and 11. In doing so, I distinguish present time and now in the introductory puzzles, investigate the passing present in the co-perception of change and time, discuss the relation between change and the passage of time as well as the relation between the passing present and the different nows.

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)

This paper offers a novel interpretation of the nature and role of logical argumentation in Aristotle’s natural philosophy. In contrast to the standard domain interpretation, which makes logikôs argumentation the contrary of phusikôs, relying on principles drawn from outside the domain of natural science, I propose that the essential or defining feature of logikôs argumentation is the use of principles that are general relative to the question under investigation. My interpretation is developed and illustrated with a close textual analysis of (...) Aristotle’s explanation of mule sterility in Generation of Animals II 8. (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)

Scholars have long considered de Philosophia and de Caelo to be in contradiction regarding the nature of the heavenly bodies, particularly with respect to the activity proper to the element composing them. According to the accounts we have of de Philosophia, Aristotle seems to have put forth that stars move because they have minds, and, according to Cicero’s account of the lost text, they choose their actions out of free will. In de Caelo, however, Aristotle seems only to consider that (...) stars engage in the activity of circular motion because it is in their nature to do so, as it is in the nature of, e.g. fire to move upwards or Earth to move downwards. In this paper, I argue against the longstanding view that there is an incompatibility between these two “early” cosmological texts of Aristotle. I aim to show that these two texts endorse complementary, not contradictory, views of the heavenly bodies. I argue that in de Philosophia, Aristotle attributes to stars the intellective counterpart of the spatial motion which is developed in greater depth in de Caelo, while in de Caelo, we see hints of Aristotle’s view in de Philosophia that the stars are also minds and are able to rationally cognize their particular good – a point which is shown in de Caelo 292a18–293a14, where Aristotle attributes both life and praxis to the heavenly bodies. The overarching view which I present of these two texts is that while de Caelo approaches the heavenly bodies qua bodies and de Philosophia approaches them qua minds, they are still examining one and the same substance and that Aristotle has not changed his mind regarding the basic nature of such a substance in the (supposed) interim between writing de Philosophia and de Caelo. Rather, we find echoes of de Caelo in de Philosophia, and echoes of de Philosophia in de Caelo, which speaks to the fact that Aristotle maintains one view of the heavenly bodies which he presents over the course of these two texts.

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.

Aristotle has qualms about the movement of the soul. He contends directly, indeed, that ‘it is impossible that motion should belong to the soul’ (DA 406a2). This is surprising in both large and small ways. Still, when we appreciate the explanatory framework set by his hylomorphic analysis of change, we can see why Aristotle should think of the soul's motion as involving a kind of category mistake-not the putative Rylean mistake, but rather the mistake of treating a change as itself (...) capable of changing.

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)

Este ensayo intenta ofrecer una reconstrucción de los argumentos de Aristóteles del uso de explicaciones teleológicas en Física II 8. En su exposición de los pasajes seleccionados Ross pone cierto énfasis en el carácter dialógico del discurso para hacer una modesta contribución a la solución de dos acertijos: uno de carácter exegético, y el otro sistemático. Esta lectura permite al autor introducir un nuevo elemento en la discusión concerniente a qué alcances y límites hay de las explicaciones teleológicas en la (...) Física de Aristóteles. En opinión de Ross, esta estrategia es útil para adelantar en la comprensión de cuál es el tipo de argumentos que pueden ofrecerse cuando lo que se está considerando es si la teleología o el mecanicismo son el esquema explicativo más apropiado para dar cuenta de los fenómenos naturales.

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. Wardy reads VII in conjunction with VIII, and argues that the former is the precursor of the latter in the development of the conception of a cosmic unmoved mover. 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. Ross and others that VII was originally a separate work, and that of the two competing versions of VII, the α-version is the preferred text, opens the way to very different philosophical conclusions from the ones that Wardy offers.

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)

Simplicius’ Commentary on Aristotle’s Categories contains the most extended testimony about the Stoic conception of acting (ποιεῖν) and undergoing (πάσχειν). Simplicius ascribed to the Stoics the idea that acting and undergoing are to be reduced to the movement. To this opinion Simplicius opposed the Aristotelian view according to which acting and undergoing are two different categories. In this paper I intend to outline the original Stoic position comparing the reportage of Simplicius with other Stoic sources. Later, I will deal with (...) Boethus’ defense of the distinction between the categories of acting and undergoing. I will argue that Boethus directly reacted against the Stoic opinion reformulating it in Aristotelian language.

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 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.

ABSTRACT:I argue that there are, according to Aristotle, two importantly different kinds of goals or ends in the domain of human agency and that one of these two kinds has been frequently, though not universally, overlooked. Apart from psychological goals, goals that agents adopt as their purposes, there are also, I submit, goals that actions have by being the kinds of actions they are and, in some cases, by occurring in the circumstances in which they do. These latter goals belong (...) to suitable actions whether or not agents adopt them as purposes and whether or not agents are aware of them. There is evidence both in Aristotle's ethical writings and in his discussion of chance and luck in Physics II.4–6 that he recognizes goals of this latter kind. (shrink)

This is my first professional philosophical essay. I wrote "The twofold meaning of being" in 1996 when I was a student of Nunzio Incardona at University of Palermo (Italy) and before my degree thesis, "The difference in Aristotle’s Metaphysics". It still waits to be published.

I will argue for the similarity between some aspects of Aristotle’s doctrine of causes and a particular kind of interventionist theory of causality. The interventionist account hypothesizes that there is a connection between causation and human intervention: the idea of a causal relation between two events is generated by the reflection of human beings on their own operating. This view is remindful of the Aristotelian concept of αἴτιον, which is linked to the figure of the αἴτιος, the person who is (...) responsible of an action. Aristotle conceives of the efficient cause as the active element which, in the φύσις, gives rise to movement and imposes the form, in analogy with the active element that in τέχνη operates the production: the craftsman. This analogy suggests that Aristotle conceives of the causation on the basis of the human ability to modify the environment with aims. Within the debate on the manipulative theory the classical accounts worked out by Collingwood, Gasking and von Wright have been recently criticized by Woodward. von Wright’s reductive account explains causation on the basis of human free action, while Woodward regards this reduction as a dangerous move which makes causal explanations too much anthropomorphic. I will show that Aristotle’s doctrine of causes is more similar to von Wright’s account and that the Aristotelian analysis of becoming supports von Wright’s reductive interventionism against Woodward’s criticism. Furthermore, I will draw a comparison between interventionism and dispositionalism, where the latter is another contemporary account of causation that claims Aristotelian roots. (shrink)

In this paper, I attempt to set out some of the main views about essence which Aristotle puts forward in Book Z of theMetaphysics.A central feature of Aristotle's account, as we shall see, is his distinction between primary and secondary cases of essence, and a similiar distinction in connection with the related notions of substance and definition. This division between primary and secondary cases means that Aristotle may well have two very different sorts of remark to make about essence, or (...) definition, or substance, according to which of the two kinds of case he has in mind. There is no reason to suppose the same logical properties apply to both the primary and the secondary cases. And when we come to define the various notions, we shall see that if our definitions are right, the logical properties in the two kinds of case are in fact quite different. (shrink)

Perhaps the real paradox of Zeno's Arrow is that, although entirely stationary, it has, against all odds, successfully traversed over two millennia of human thought to trouble successive generations of philosophers. The prospects were not good: few original Zenonian fragments survive, and our access to the paradoxes has been for the most part through unsympathetic commentaries. Moreover, like its sister paradoxes of motion, the Arrow has repeatedly been dismissed as specious and easily dissolved. Even those commentators who have taken it (...) seriously have propounded solutions with which they profess themselves to be perfectly satisfied. So my question is: will Zeno's Arrow survive into the millennium just begun? (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 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" . 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 brie fly and somewhat speculatively with a suggestion as to why Aristotle might accept the principle on which I have suggested the problem turns. (shrink)

Aristotle introduces Physics I as an inquiry into principles; in this paper I ask where he argues for the position he reaches in I 7. Many hold that his definitive argument is found in the first half of I 7 itself; I argue that this view is mistaken: the considerations raised there do not form the basis of any self-standing argument for Aristotle's doctrine of principles, but rather play a subordinate role in a larger argument begun in earnest in I (...) 5. This larger argument stalls in I 6, which ends in aporta; I argue that the problem lies in the fact that Aristotle's reasoning in I 6 thoroughly undermines his reasoning in I 5 (on which I 6 is ostensibly supposed to build). I further argue that the materials necessary for resolving this problem, and thereby allowing the argument begun in I 5 to reach its proper conclusion, are supplied by the thesis that organizes the first half of I 7. Along the way I offer some remarks about Aristotle's doctrine of principles, arguing that it is about the principles of natural substance (as opposed to coming to be or change). I also offer some remarks about the thesis which organizes the first half of I 7.1 argue negatively that it is not anything like a preliminary statement of Aristotle's doctrine of principles. I argue positively that it reflects Aristotle's idea that there are two distinct kinds of effect change has upon things (one constructive, the other destructive). One of these effects lies behind Aristotle's reasoning in I 5, the other comes to the fore in 16; the achievement of the first half of I 7 is to reconcile these seemingly competing conceptions by finding a place for them both in a unified account of coming to be and its subjects.
