Aristotle: Metaphysics

The Aristotelian view of universals, according to which each universal generically depends for its existence on its instantiations, has recently come under attack by a series of ground-theoretic arguments. The last such arguments, presented by Raven, promises to offer several significant improvements over its predecessors, such as avoiding commitment to the transitivity of ground and offering new reasons for the metaphysical priority of universals over their instantiations. In this paper, we argue that Raven's argument does not effectively avoid said commitment (...) and that Raven's new reasons fail. Moreover, we present a novel ground-theoretic interpretation of the Aristotelian view, referred to as strong immanence, and introduce a new argument against the Aristotelian view, intended to sidestep any commitment to the transitivity of ground.

In In V Metaphysics, lec. 9, Aquinas distinguishes between “being by accident” (ens per accidens) and “being by itself” (ens per se) and includes the nine accidental categories under the latter. But isn’t substance a being per se while accidents are, by definition, accidental beings? Several authors—including Ralph McInerny, Paul Symington, and Greg Doolan—have offered explanations of this strange classification. Drawing on an overlooked parallel text in the Posterior Analytics commentary and on Aquinas’s critique of Avicenna’s understanding of accidental denominatives, (...) this paper presents an alternative explanation of the lecture. In the process, it clarifies how Aquinas views the relation of the ten categories to predication and suggests important implications for how we should understand the analogy of being and the phrase “substantial being” (esse substantiale).

O presente artigo tem como objetivo principal esclarecer a concepção da tradição megárica acerca do conceito de capacidade (δύναμις), tal como apresentada no livro Theta da Metafísica de Aristóteles. A análise se faz necessária devido à falta de atenção aristotélica na formulação da tese adversária dos megáricos, pois em nenhum momento Aristóteles parece nos oferecer argumentos plausíveis que justifiquem de maneira adequada a tese de seus oponentes. Partindo desta dificuldade de reconstrução do argumento megárico e visando lhe oferecer uma maior (...) dignidade, o estudo irá, em primeiro lugar, destrinchar possíveis argumentos que sustentem a tese no contexto da referida obra. Em seguida, irá provar que, mesmo a tese megárica não sendo tão facilmente refutável como uma primeira leitura poderia sugerir, há em sua estrutura problemas graves, que se evidenciam diante da concepção aristotélica da capacidade.

In book Λ. of the Metaphysics, Aristotle suggests that an unmoved, unmoving being (God) is the source of all movement in the cosmos. He explains that this being instigates movement through desire. But how does desire affect movement? And what would make Aristotle’s God an object of desire? I attend to both questions in this paper, arguing that God’s existence as pure actuality (energeia) is crucial to understanding God’s status as the primary and ultimate source of wonder, and that it (...) is as the ultimate source of wonder that we can make sense of how God affects desire.

The discussion of the Principle of Non-Contradiction (PNC) in Aristotle’s Metaphysics Γ is usually taken to include three ‘versions’ of the principle: an ontological, psychological, and logical one. In this article I develop an interpretation of Metaphysics Γ3 and a parallel text, De interpretatione 14, in order to show that these texts are concerned with two related but different principles: a version of the Principle of Identity, and a corollary to this, which concerns the ability to accept two ‘opposite’ items (...) at the same time. I argue that these principles must be considered separately in order to properly understand Aristotle’s remarks about PNC in Metaphysics Γ, and in order to defend his approach in these remarks against certain objections raised against the discussion in Metaphysics Γ by Jan Łukasiewicz in his "Über den Satz des Widerspruchs bei Aristoteles". The main result of my interpretation is to distinguish in the discussion of PNC in Metaphysics Γ three principles: one concerning linguistic items (words and statements), one concerning thoughts (δόξαι), and one concerning objects or states of affairs.

El desarrollo humano es, en el contexto de los estudios del desarrollo internacional, un concepto difundido a partir de 1990 por el Programa de las Naciones Unidas para el Desarrollo (PNUD). Este artículo propone una interpretación alternativa del concepto de desarrollo humano que resuelve algunas inconsistencias producidas por la confluencia de las distintas corrientes teóricas que dieron origen al concepto. La nueva interpretación propuesta proviene de los aportes del enfoque aristotélico de Martha Nussbaum y, más directamente, de la antropología aristotélica (...) y las nociones de acto y potencia. Se argumenta que el desarrollo humano puede ser entendido como el cambio que busca la realización plena del potencial humano. (shrink)

The object of our reflection is to examine whether Aristotle's proof of the eternity of the Universe has a scientific character or only a dialectical one, as Thomas Aquinas claims. On this response depends faith in Creation. -/- L’objet de notre réflexion est d’examiner si la preuve de l’éternité de l’Univers avancée par Aristote a un caractère scientifique ou bien seulement dialectique, comme le prétend Thomas d’Aquin. De cette réponse dépend la foi en la Création.

In this paper, I compare the Megarian thesis of Metaphysics IX 3 with other sources on the Megarians in order to clarify two questions: that of the unity and nature of the so-called Megarian school and that of Aristotle’s broader argument in IX 3. I first review the disputed issue of the status of the Megarian school and then examine two hypotheses regarding the identity behind Aristotle’s allusion in IX 3. Third, I explore the connection between Megarianism and Plato’s Euthydemus, (...) a task that helps us to contextualize Aristotle’s anti-Megarian polemic. Lastly, I build on the preceding argument in a re-examination of the Eleatic hypothesis with regard both to the Megarians as a whole and to the thesis that Aristotle transmits. (shrink)

In this paper, I argue that Aristotle was already aware in his earlier texts of the fundamental distinction between motion and activity and of the criterion which structures this contrast. Moreover, I will present textual evidence which suggests that Aristotle’s original concept of ἐνέργεια applies primarily to activities which contain their ends in themselves, and not to motions, which are different from their ends.

Many contemporary philosophers hold that comparison requires a common, monistic ‘covering value’, and Aristotle is often described as a forerunner of this view. This paper reconsiders that claim. First, its textual warrant is substantially weaker than has been thought. Philosophically, moreover, Aristotle’s theory of non-synonymous predication allows for comparisons to be made using the special kind of non-synonymous terms that he calls pros hen legomenon, literally those ‘said with reference to a single thing.’ His favourite example is ‘healthy’ as said (...) of food, organisms, and medical procedures: these various senses are not entirely synonymous, yet are not simply unconnected. This has significant implications. Aristotle famously holds that goodness is species-specific, and it would then seem that species cannot be ranked according to how good they are. Yet Aristotle does—frequently—rank species. The paper shows us that he is not, pace other scholars, thereby caught in a contradiction. -/- . (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.

In the following article I present some general features of the Concept that may be understood without resorting to dialectical logic. Primarily, it is intended for beginning students of Hegel's philosophy, and also to provide an intuitive grasp of the Concept for those who may be struggling to understand what Hegel means by this important term that is so central to the philosophical science of the Absolute. Hegel considered that Aristotle also analyzed the Concept without dialectics, so it is shown (...) here how Aristotle was, in fact, dealing with the Concept in his own metaphysics. Basically, it is concluded that an object is a unity of two essential determinations: (1) its being or that it is, and (2) its other determinations or what it is. This leads to understanding that the object is actually a subject-object unity or identity. The Concept is the concrete totality of these aspects and their relations, and provides a new foundation beyond empiricism for scientifically comprehending objects and objective reality in general. (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. -/- .

The discussions of conatus – force, tendency, effort, and striving – in early modern metaphysics have roots in Aristotle’s understanding of life as an internal experience of living force. This paper examines the ways that Spinoza’s conatus is consonant with Aristotle on effort. By tracking effort from his psychology and ethics to aesthetics, I show there is a conatus at the heart of the activity of the ψυχή that involves an intensification of power in a way which anticipates many of (...) the central insights of early modern and 20th century European philosophy. The first section outlines how Aristotle’s developmental conception of the soul as geometrically ordered lays the foundation for his understanding of effort. The developmental series of powers of the soul are analogous to the series of shapes in mathematics. The second section links the striving of the soul to the gradual acquisition of virtues as a directed activity unifying multiplicity. The third examines the paradigm of self-awareness that Aristotelian effort involves. In the final section I show how ancient Greek theories of music were founded on the experience of striving. The “nature” of music is defined by Aristoxenus, and Theophrastus, in relation to the passion and intentionality of the soul. The geometrical order, as a synthesis of elements in geometry, music, or ethics, is a generative process in which past elements are retained and reintegrated in later stages of development. It requires effort to think geometrically, and the progress of knowledge itself is an integral aspect of all effort. Effort is the lived and self-aware cause which, moving step by step in an orderly and deliberate way, grows and advances upon itself. For both Spinoza and Aristotle, effort is the immanent intelligence which accomplishes what is in the purview of its understanding. Thus, will, in this conception of effort, is not something we already possess innately, but emerges gradually by an effort aimed at improvement. (shrink)

Quoique l’on trouve plusieurs explications de l’ontologie du Bien dans l’œuvre d’Aristote, on n’y trouve qu’une seule explication de l’ontologie du mal. En Métaphysique Θ 8 et 9, la description du rapport entre la puissance et l’acte prépare le chemin vers une explication ontologique du mal comme la privation d’un bien. Le but de cet article est de montrer que cette doctrine du mal comme privation constitue le fondement métaphysique de toute la philosophie pratique aristotélicienne et d’illustrer la continuité entre (...) les doctrines de la vertu, du vice et du bonheur et la doctrine du mal comme privation.

Aristotle gives a surprisingly broad menu of examples of something being accidental to something else. But the breadth of these examples seems to threaten a basic feature of accidentality, namely its asymmetry. ‘Accident’ has different senses, and one might think that that fact offers a way out, but some examples resist such an understanding. The best way forward, I argue, is to take accidentality to be contextual: relative to some context or condition, something might be accidental to something else; relative (...) to another context or condition, the latter might be accidental to the former.

This paper aims to argue for, else illustrate the epistemological significance of the use of non transitive similarity relations, mapping only to "types", as methodologically being on a par with the use of transitive similarity relations (equivalence relations), mapping as well to "predicates". -/- In this paper the sketch of an exact but simple geometrical model of the above construct is followed by mentioning respective use cases for non transitive similarity relations from science and humanities. A well known metaphysics example (...) is elaborated along these lines to some extent. (shrink)

Biology and theology are interdependent theoretical sciences for Aristotle. In prominent discussions of the divine things (the stars and their unmoved movers) Aristotle appeals to the science of living things, and in prominent discussions of the nature of plants and animals Aristotle appeals to the nature of the divine. There is in fact a single continuous series of living things that includes gods, humans, animals, and plants, all of them in a way divine. Aristotle has this continuum of divine beings, (...) and a theory of value that corresponds to it, in mind not only in key parts of his theology and biology, but also in his practical philosophy. Here I call attention to some important texts and attempt to offer a coherent account of them, without being able to enter into the usual interpretive disputes. I begin by clarifying the terms “theology” and “biology” and their place in Aristotle's division of philosophy. Next, I discuss how Aristotle’s theology is informed by his biology, and then how his biology is informed by his theology. I end by discussing some implications of the interdependence of biology and theology for Aristotle’s ethics and exhortation to philosophy. (shrink)

Is there grounding in ancient philosophy? To ask a related but different question: is grounding a useful tool for the scholar of ancient philosophy? These questions are difficult, and my goal in this paper is not so much to give definitive answers as to clarify the questions. I hope to direct the student of contemporary metaphysics towards passages where it may be fruitful to look for historical precedent. But I also hope to offer the student of ancient philosophy some guidance (...) on when drawing on the contemporary discussion of grounding may be beneficial. (shrink)

Aristotle (384-322 B.C), a well know Greek philosopher, physician, scientist and politician. A variety of identifying researches have been written on him. It is therefore a considerable pride for the researcher to write something about him when even mentioning his name and his father's name is a point of prestige in the Greek Language. His name means the preferable sublimity whereas Nicomachus (his father's name) means the definable negotiator. His father's and mother's origin belongs to Asclepiade, the favorite origin in (...) Greek. Points of view regarding this figure are controversial some praise him and consider him the peak of philosophical thinker which makes humanity in general owe this genius thinker a great deal. Others believe that the effect of his thought on humanity is the reason behind the non-progress of science. Whatever ones opinion is, his thoughts have a wonderful force in stimulating and positively affecting the people's thinking. His philosophy is the greatest philosophy which the world has ever witnessed or which may ever witness., if it couldn’t solve some of the problems of philosophy, it at least, makes the world more rational than before. He is the founder of the philosophical language in describing a large number of philosophical terms which are still in use nowadays. Moreover his books and platonic dialogues are considered encyclopedias in providing a basis for philosophy even before Socrates. For theses among other reasons, I am choosing Aristotle as a subject for research and concentrating on natural philosophy. The critical side deals with the criticism of natural philosophers. In order to fully understand Aristotle, we should understand his predecessors. Their virtue is undeniable. Without them, Aristotle's and Plato's genius would never be in this ideal shape. In addition to that, they are philosophers and scientists who mixes between science, philosophy, morality and politics in a complementary form. They are a source of illumination to the human thinking in general. Without them humanity could never have got rid of mythology. This is the code of life, for many generations should pass before the rare genius could attain a prominent idea. When Tales formulates the philosophical question, where does the world come from? This is a decisive moment in human thinking similar to the coming moments, the one Parmenides, and Protagoras statement: man is the norm for all things. Pre-Socrates philosophers are all considered glowing points in drawing Aristotle's philosophy. Thus my book is entitles (Aristotle's criticism of Pre-Socratic Natural Philosophy) which means the concentration on the critical operation through which the natural side of the previous philosophers appears. The nature of the title forces me to deal with Aristotle's ideas from every point of view. Thus the book proceeds according to structure and criticism and the construction of Aristotle's philosophy. Because the title is comprehensive and limited simultaneously, I have chosen the critical subjects in the lights of the natural philosophy. I have divided the book into four chapters with fourteen sections in addition to the implemented parts included in every section purporting to cover every part of criticism looking for comprehensiveness. I have found it obligatory to mention something about Aristotle's view in criticism, in addition to a precise delimitation of nature and its subjects. This is the subject of the first chapter. The second chapter deals with the principles of natural body, i.e., the principles dealt with pre-Aristotle philosophy and then these three principles (Hyle, form ,and Non-being). After delaminating these sides, it is possible to deal with the details (Movement, Place, Time, Vacuum and Infinite) which are natural concepts for the third chapter. As a complementation to the natural sides, the chapter four deals with two topics , Universal and corruption, and theory of elements. This book, in my own opinion, is comprehensive to the majority of natural philosophers and it focuses on the argument of Aristotle's criticism to the views of natural philosophers before Socrates together with the discussion of the Aristotelian alternative from these points of view. Aristotle sometimes tends to praise the previous philosophers. This does not mean the non-conformity between what he wants to say and what they described. When he, for example, says that the previous philosophers realized the material defect in Thales idea that water is the origin of all things but Thales’ water is not like Aristotle's Hyle, it is completely different thing. Finally I have viewed the index of Arab Library, and was unable to trace a book which is especially oriented in this subject i.e. writings on Aristotle's criticism to natural philosophy before Socrates. Therefore I have been stimulated to write about a very new subject. This subject fills a gap in Arab studies. (shrink)

In Measuring the Immeasurable Mind: Where Contemporary Neuroscience Meets the Aristotelian Tradition, Matthew Owen argues that despite its nonphysical character, it is possible to empirically detect and measure consciousness. -/- Toward the end of the previous century, the neuroscience of consciousness set its roots and sprouted within a materialist milieu that reduced the mind to matter. Several decades later, dualism is being dusted off and reconsidered. Although some may see this revival as a threat to consciousness science aimed at measuring (...) the conscious mind, Owen argues that measuring consciousness, along with the medical benefits of such measurements, is not ruled out by consciousness being nonphysical. Owen proposes the Mind-Body Powers model of neural correlates of consciousness, which is informed by Aristotelian causation and a substance dualist view of human nature inspired by Thomas Aquinas, who often followed Aristotle. In addition to explaining why there are neural correlates of consciousness, the model provides a philosophical foundation for empirically discerning and quantifying consciousness. En route to presenting and applying the Mind-Body Powers model to neurobiology, Owen rebuts longstanding objections to dualism related to the mind-body problem. With scholarly precision and readable clarity, Owen applies an oft forgotten yet richly developed historical vantage point to contemporary cognitive neuroscience. (shrink)

Our everyday knowledge and the knowledge of the sciences are based on presuppositions of different fundamentality. The most general framework includes opinions about being, then the way a particular language sorts reality, precepts of logic, what Husserl called the natural attitude. Furthermore, specific content-related prerequisites and convictions are decisive in the individual sciences. Also modern readers of Aristotelian texts share some such specific convictions. I would like to speak of two of them here, since they are evidently false and considerably (...) hindering the understanding of the texts. The first conviction is that Aristotle developed a metaphysics of substance, the second that he thereby founded a theology with an ‘unmoved mover’ as its center, which can be identified with God. Since this text is a kind of pamphlet, I have summarized the remarks in endnotes. (shrink)

This paper reexamines Theophrastus’ Metaphysics 11a18–26, an obscure testimony about Speusippus, the second head of the Platonic Academy. As opposed to the traditional interpretation, which takes this passage as Theophrastus’ polemic against Speusippus’ doctrine of value, I argue that he here dialectically takes advantage of, rather than launches an attack on, the Platonist. Based on this new reading, I further propose a revision and a reassessment of the ‘gloomy metaphysics’ of Speusippus which will shed new light on his ethics.

In Metaphysics Λ.6-7 Aristotle argues that an unmoved substance causes the outermost sphere to rotate. His argument has puzzled and divided commentators from ancient Greece to the present. I offer a novel defense of Aristotle's argument by highlighting the logic of classification that Aristotle deploys. The core of Aristotle's argument is the identification of the unmoved substance on the 'table of opposites' as simple and purely actual. With this identification in place, Aristotle argues that the outermost sphere activates its capacity (...) to relocate its body by rotating because this is how it can be a simple and actual substance. But unlike traditional attempts to rehabilitate Aristotle's argument, I argue that the sphere does not rotate in order to imitate the Prime Mover. Rather, the sphere rotates because that is good for it to do, and the Prime Mover is a metaphysically necessary source of simple and actual substantial being, which the sphere acts for the sake of.

The fundamental error of the metaphysical tradition, according to Heidegger, is the subordination of general ontology to the ontology of a special, exemplary entity (God, the soul, etc.). But Being and Time itself treats one kind of entity as exemplary, namely Dasein. Does this mean that Heidegger fails to free himself from the kind of metaphysics that he sought to criticize? To show how he avoids this charge I propose to examine the parallels between the methodology of Being and Time (...) and the methodology Heidegger ascribes to Aristotle's Metaphysics. Heidegger takes the virtue of Aristotle's inquiry to reside in the way he resists the subordination of general to special ontology: Aristotle was guided by a "double concept" of metaphysics, pursued two irreducibly distinct methods of inquiry, and avoided the temptation to unite them. In proposing to similarly pursue a "double task" in Being and Time Heidegger seeks to apply this insight to his own work. Alongside the task of fundamental ontology, Heidegger spells out the shape of a second task, Destruktion, understood as a historical critique that traces ontological concepts back to their ontic roots. But Destruktion is not a mere addendum to fundamental ontology; the two tasks are meant to counterbalance one another and thereby prevent the collapse of the ontological difference between being and beings. Indeed, Heidegger proposes to apply Destruktion to the results of his own fundamental ontology. He hopes to thereby achieve a transformation of the philosophical attitude which underpins the metaphysical tradition. (shrink)

This essay argues that Schelling's late transition from Negative to Positive Philosophy constitutes a pointed inversion of the path of systematic ascent mapped by Hegel for the first time in the Phenomenology's Preface, which itself establishes Hegel's development out of and beyond Schelling's early philosophy; that a key notion to inspire the Hegelian vision articulated in the Preface returns to cap off the critique implicit in Schelling's late inversion, where this notion emerges from their divergent readings of Aristotle's Metaphysics; and (...) finally, that while Hegel's theorization of the end of all philosophizing represents his innovative enlargement from within the framework he finds in Aristotle, Schelling's vision of this same end facilitates the crisis of reason which opens unto revelation, and so is akin to the vision which carries Aquinas beyond Aristotle, albeit in Schelling's post‐Spinozist mode of thought.

I argue there are two ways predication relations can hold according to the Categories: they can hold directly or they can hold mediately. The distinction between direct and mediated predication is a distinction between whether or not a given prediction fact holds in virtue of another predication fact’s holding. We can tell Aristotle endorses this distinction from multiple places in the text where he licenses an inference from one predication fact’s holding to another predication fact’s holding. The best explanation for (...) each such inference is that he takes some predication facts to be mediated by others. Once the distinction between direct and mediated predication has been explained and argued for, I show how it can help solve a persistent problem for the traditional view of non-substantial particulars in the Categories—that is, the view that non-substantial particulars are particular in the sense of being non-recurrent. Along with vindicating the traditional view, the direct/mediated predication distinction gives us a distinctive way of understanding what it is for something to be recurrent (or non-recurrent) as well as a better understanding of Aristotle’s broader commitments in the Categories as a whole.

A curious feature of Aztec philosophy is that the basic metaphysical question of the “Western” tradition cannot be formulated in their language, in Nahuatl. This did not, however, prevent the Aztecs from developing an account of 'reality', or whatever it is that might exist. The article is the first of its kind to compare the work of Aristotle on ousia (being) and the Aztecs on teotl and ometeotl. Through this analysis, it suggests that both of the Nahuatl terms are fundamental (...) for expressing the basic character of reality as process for the Aztecs. It also defends their notion as prima facia reasonable, despite its wide divergence from Aristotle's view. (shrink)

This chapter argues that it is possible to identify, in the coming to be of knowledge, the three elements that Aristotle says are involved in any kind of coming to be whatsoever (viz., matter, form, and the generated composite object). Specifically, it is argued that in this schema the passive intellect (pathetikos nous) corresponds to the matter, the active intellect (poetikos nous) corresponds to the form, and the composite object corresponds to the mind as actually knowing.

Recently, a strong hylomorphic reading of Aristotelian emotions has been put forward, one that allegedly eliminates the problem of causal interaction between soul and body. Taking the presentation of emotions in de An. I 1 as a starting point and basic thread, but relying also on the discussion of Rh. II, I will argue that this reading only takes into account two of the four causes of emotions, and that, if all four of them are included into the picture, then (...) a causal interaction of mind and body remains within Aristotelian emotions, independent of how strongly their hylomorphism is understood. Beyond the discussion with this recent reading, the analysis proposed of the fourfold causal structure of emotions is also intended as a hermeneutical starting point for a comprehensive analysis of particular emotions in Aristotle. Through the different causes Aristotle seems to account for many aspects of the complex phenomenon of emotion, including its physiological causes, its mental causes, and its intentional object.

This note falls into two main parts. In the first part, I shall consider the question of whether or not Aristotle believed that there can be true statements about what will happen in the future. I will first clarify this question, which will involve consideration of some logical and metaphysical notions in Aristotle. I will then argue that the answer to the question is ‘No’ (with a qualification). In the second part, I shall argue that his view is correct. I (...) will do this ‘indirectly’, by way of presenting and refuting three prominent objections to the view. (shrink)

_ Source: _Volume 63, Issue 1, pp 64 - 86 Five times in the extant corpus, Aristotle refers to a distinction between two ways of being a ‘that for the sake of which’ that he sometimes marks by using genitive and dative pronouns. Commentators almost universally say that this is the distinction between an aim and beneficiary. I propose that Aristotle had a quite different distinction in mind, namely: that which holds between something and the aim or objective it is (...) in the business of producing or achieving, and that which holds between some instrument and the user of that instrument.

Being has been the central and dominating concept of twenty-five hundred years of Western philosophy. Ontology is the branch of metaphysics that concerns itself with the nature of being. In this sense it is at the core of metaphysics and is the central problem of philosophy. As Aristotle has put it, “That which now and always has been asked and now and always perplexes us is the question: ‘what is being?’” Aristotle did not use the word ontology, but called the (...) study of being, “First Philosophy”. The special sciences study being “in some way”, το ον πως, whereas “first philosophy” studies being as being, being qua being, being as it is in itself; το ον η ον, or as Plato had put it before him, the being of being, το όντως ον. First philosophy, therefore, is a science which is prior to all the other sciences and is therefore termed the science of sciences, επιστήμη επιστημών. (shrink)

Modern philosophy is, for what appear to be good reasons, uniformly hostile to sui generis final causes. And motivated to develop philosophically and scientifically plausible interpretations, scholars have increasingly offered reductivist and eliminitivist accounts of Aristotle's teleological commitment. This trend in contemporary scholarship is misguided. We have strong grounds to believe Aristotle accepted unreduced sui generis teleology, and reductivist and eliminitivist accounts face insurmountable textual and philosophical difficulties. We offer Aristotelians cold comfort by replacing his apparent view with failed accounts. (...) And so we ought to admit Aristotle’s prima facie commitments and deal with — if not accept — the consequences. (shrink)

In Metaphysics A, Aristotle offers some objections to Plato’s theory of Forms to the effect that Plato’s Forms would not be explanatory in the right way, and seems to suggest that they might even make the explanatory project worse. One interesting historical puzzle is whether Aristotle can avoid these same objections to his own theory of universals. The concerns Aristotle raises are, I think, cousins of contemporary concerns about the usefulness and explanatoriness of abstract objects, some of which have recently (...) been receiving attention in the philosophy of mathematics. After discussing Aristotle’s objections and their contemporary cousins, the paper discusses some of the main available lines of response to these sorts of challenges, before concluding with an examination of whether these responses could assist Plato or Aristotle in responding to these challenges.

Platónovy pokusy o určení dobra lze nalézt v celém jeho díle. Zahrnují jak relativně „univoční“ koncepci dobra ve smyslu sókratovského intelektualismu, tak pluralističtější koncepci obsaženou v politickém projektu Zákonů. Podle vývojové interpretace Platónových dialogů to naznačuje posun v autorově myšlení způsobený poznáním obtížnosti problému. Byl to přitom údajně teprve Aristotelés, kdo vyřešil Platónův problém dobra pomocí pojmu analogie. Proti této interpretaci článek zdůrazňuje, že aristotelské pojetí analogie je hluboce zakořeněno v Platónově vlastním potýkání se s rozdílem mezi morálním a politickým (...) dobrem. Byla to především Platónovo pochopení specifické hodnoty politické plurality, které stojí v základě akademického rozlišení mezi analogia a pros hen. (shrink)

The difficult phrase ὅ ποτε ὄν ἐστι (hereafter ‘OPO’), which occurs in key passages in Aristotle’s discussions of blood and of time, has long vexed interpreters of Aristotle. This paper proposes a new interpretation of OPO, which resolves some textual and interpretative problems about Aristotle’s theories of blood and of time. My interpretation will also shed light on more general issues in Aristotle’s metaphysics. In the passages I will discuss, Aristotle takes both blood and time to be examples of his (...) peculiar ‘coupled entities’. He then uses OPO to provide explanations which differ from what we might call his ‘standard’ metaphysical explanations. On the ‘standard’ approach, Aristotle explains derivative entities—non-substances—by describing their relationship to substances. By contrast to this standard form of explanation, when Aristotle uses OPO he explains blood and time by describing their relationship to non-substances. This paper thus identifies a new species of metaphysical dependence in Aristotle. In addition, it provides detailed examination of evidence concerning whether Aristotle himself used coupled entities in his own physical and metaphysical theories. (shrink)

The paper contains a novel realist account of causal production and the necessary connection between cause and effect. I argue that the asymmetric relation between causally connected events must be regarded as a product of a symmetric interaction between two or more entities. All the entities involved contribute to the producing, and so count as parts of the cause, and they all suffer a change, and so count as parts of the effect. Cause and effect, on this account, are two (...) different states of the very same compound substance, or system, one coming to exist out of the other. (shrink)

Arguably one of the most fundamental phase shifts that occurred in the intellectual history of Western culture involved the ontological reduction of secondary qualities to primary qualities. To say the least, this reduction worked to undermine the foundations undergirding Aristotelian thought in support of a scientific view of the world based strictly on an examination of the real—primary— qualities of things. In this essay, I identify the so-called “Causal Argument” for a reductive view of secondary qualities and seek to deflect (...) this challenge by deriving some plausible consequences that support a non-reductive view of secondary qualities from an Aristotelian view (via the philosophical commentary of Thomas Aquinas). Specifically, my argument has two facets. First, I show that Aristotle’s view both implies recognition of the extramental existence of secondary qualities and is a prima facia natural view to take regarding the ontology of secondary qualities. Second, I show that the Causal Argument, which is thought to undermine a natural view of secondary qualities as real things, loses its bite when one examines perception in light the ontological relationship among the categories of quality, quantity and substance.

In this paper, I try to show how the intellect and the reality go together by a metaphysical analysis of the intellectual potency. According to the classical think, there is a true ‘idealist’ way to considerate the intellect. In the divine intellect there is —ontologically— all being that is present —logically— in God’s mind.

In the last few years, a new paradigm of the knowledge of the divinity in Aristotle has emerged, affording the possibility of understanding him as efficient cause. In that case, if God is efficient cause and gives rise to teleology, this must have some existential significance for man. We can ask ourselves therefore whether the knowledge of metaphysics can offer some orientation also for ethics. Yet if this were true, the need would arise to deepen the question of how much (...) the gods love men and what would the nature of their relationship be to natural justice. Given that man is born and lives thanks to the divinity, the conclusion is that two consequences follow: a response of religious thanksgiving is needed but also, that since the will of the divinity desires the good for man, the human search for happiness is the same as the fulfillment of the divine law. All this is explained, to a certain extent, in the context of the friendship between man and the divine. (shrink)

In Physics IV 14, 223a16-223a29 Aristotle raises two questions: (Q1) How is time related to the soul? (Q2) Why is time thought to be in everything? Aristotle's juxtaposition of these questions indicates some relation between them. I argue that Aristotle is committed to the claim that time only exists where change is countable. Aristotle must answer (Q2) in a way that doesn't conflict with this commitment. Aristotle's answer to (Q1) offers him such a way. Since time is change qua countable, (...) time is dependent on souls capable of counting. But the thing that time is, change, is not so dependent. Likewise, time is not located in everything, but change, the substratum of time, is. This answers (Q2) in a way that's compatible with Aristotle's commitments. (shrink)
