Aristotle: Metaphysics

There are no older, complete and extensive western philosophical texts to read than Plato’s and Aristotle’s. The themes of both corpora are manyfold and they had all the time a very strong and different reception and impact. Aristotle’s texts were used for different aims which lead to some convictions that became solid as concrete. Nobody, or almost nobody doubts that Aristotle has developed a metaphysics with substance at its core, that the high point and the ‘coping stone’ of this metaphysics (...) is a theology with a God allegedly called by Aristotle ‘unmoved mover’ (note: an expression Aristotle never uses). He also is credited with a natural science, the only point of contention is whether that was for the better or for the worse. In the 19th and 20th centuries the hermeneutical situation to read Aristotle’s texts has changed drastically. We have at our disposal editions that are easily available and more reliable than ever, we know that the texts were not designed at the desk like texts of modern philosophers, Kant or Husserl, they were preparations of the docent for his lectures or seminars, we have learned that not every philosophy must build a system, we have understood the origin of his vocabulary in the ordinary language, the idea of a philosophia perennis has proven itself to be time-bound, it has become evident that it were Neo-platonic texts, ascribed to Aristotle, which have plunged his texts in a theological light. Such developments allow and force us to to read the texts with new eyes. We must set aside the presuppositions from the Middle Ages, especially the metaphysics of substance and its theological consequences, they have no basis in the texts. We can learn from Aristotle that it is necessary and possible to reflect on the basic beliefs of our time and of our world, and, how to do that: by speculation in topical attitude. The report of the results is given in the manner of ‘thinking without contention’ (unbehauptendes Denken). He gives an example of a world without substance and subject. (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)

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)

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 paper examines Aristotle’s discussion of the priority of actuality to potentiality in geometry at Metaphysics Θ9, 1051a21–33. Many scholars have assumed what I call the ‘geometrical construction’ interpretation, according to which his point here concerns the relation between an inquirer’s thinking and a geometrical figure. In contrast, I will defend what I call the ‘geometrical analysis’ interpretation, according to which it concerns the asymmetrical relation between geometrical propositions in which one is proved by means of the other. His argument (...) as so construed is ultimately based on the asymmetrical relation between the corresponding geometrical facts. Then I explore this ontological priority in geometry by drawing attention to the parallel passage Posterior Analytics II.11, 94a24–35, where Aristotle explains the relation between the same geometrical propositions in connection to material causation.

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)

It is also worth investigating how time is related to the soul, and for what reason it is that time is thought to be in everything - on earth and in the sea and in the heavens. Is it that it is a property or a state of change, being the number [of it], and all these things are changeable, since they are all in place, and time and change are together both in potentiality and in actual operation? One might (...) find it a difficult question, whether if there were no soul there would be time or not. For if it is impossible that there should be something to do the counting, it is also impossible that anything should be countable, so that it is clear that there would be no number either, for number is either that which has been counted or that which can be. But if there is nothing that has it in its nature to count except soul, and of soul [the part which is] intellect, then it is impossible that there should be time if there is no soul, except that there could be that X which time is, whatever X makes it what it is; as for example if it is possible for there to be change without soul. The before and after are in change, and time is these qua countable. (223a16-29). (shrink)

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)

A survey of theories of part, whole and dependence from Aristotle to the Gestalt psychologists, with special attention to Husserl’s Third Logical Investigation “On the Theory of Parts and Wholes”.

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 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)

Introduction to my 'Contemporary Aristotelian Metaphysics' volume.

In this paper I examine what exactly is ‘Aristotelian metaphysics’. My inquiry into Aristotelian metaphysics should not be understood to be so much concerned with the details of Aristotle's metaphysics. I am are rather concerned with his methodology of metaphysics, although a lot of the details of his metaphysics survive in contemporary discussion as well. This warrants an investigation into the methodological aspects of Aristotle's metaphysics. The key works that we will be looking at are his Physics, Metaphysics, Categories and (...) De Interpretatione. Perhaps the most crucial features of the Aristotelian method of philosophising are the relationship between science and metaphysics, and his defence of the principle of non-contradiction (PNC). For Aristotle, natural science is the second philosophy, but this is so only because there is something more fundamental in the world, something that natural science – a science of movement – cannot study. Furthermore, Aristotle demonstrates that metaphysics enters the picture at a fundamental level, as he argues that PNC is a metaphysical rather than a logical principle. The upshot of all this is that the Aristotelian method and his metaphysics are not threatened by modern science, quite the opposite. Moreover, we have in our hands a methodology which is very rigorous indeed and worthwhile for any metaphysician to have a closer look at. (shrink)

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

The present text is the revised and corrected English translation of the book published in German by the Lang Verlag, Bern 2008. Unfortunately the text still has some minor flaws (especially in the Index Locorum) but they do not concern the main thesis or the arguments. It will still be the final version, especially considering my age. It is among the most widespread and the least questioned convictions that in Metaphysics Lambda Aristotle presents a theology which has its basis in (...) a metaphysics of substance. Doubts about theological interpretation are beginning to stir in a growing number of publications, but nevertheless the majority of research literature, compendiums and histories of philosophy argues within this frame. A closer look at the facts reveals that this conviction has no basis in the text. Quite the contrary it is based on a reception with theological interests. It arised over centuries, starting from Patristic times and the Middle Ages; it was influenced by Neoplatonic texts as the Liber de Causis or the Theologia Aristotelis, texts for a long time considered as original Aristotelian books. And, if you read not translations but the Greek text, you see that the word 'god' occurs much less than in a theological book should be. In some translations we find more occurences of that word, and especially in French, Italian, English translations some words as le Bien, l'Intelligence etc. are written with capitals to inticate that it is about god. To make it even more clear, we read often the term 'First Mover' or 'Unmoved Mover' as an other name for god, but this expression is never used by Aristotle. So the reader has the impression that Aristotle speaks continuously about god. In addition, in the present book you will find arguments which clean up with the outdated concept of substance in the Aristotelian text, a concept which was developed for quite other problems than Aristotle had, namely theolgical ones. And, if there is no substance, there is no corresponding metaphysics of substance and no theology or onto-theology. If substance, metyphysics, theology play no role in Metaphysics Lambda, what else is its content and aim? That is not so difficult to say because Aristotle says it sufficiently clear in his first sentence, περὶ οὐσίας ἡ θεωρία: our inquiry is about being; its aim is to develop the Frage nach dem Sein and to state a speculative answer: being is noesis, Sein ist Gewahren.

There are several passages in the Metaphysics where Aristotle explains ontological priority in terms of ontological dependence, but there are others where he seems to adopt a teleological conception of ontological priority. It is sometimes maintained that the latter priority too must be construed in terms of the former, or that the priorities in question are not both endorsed (or simultaneously endorsed) by Aristotle. The goal of this paper is to show otherwise; I argue that what is at issue are (...) two distinct priorities that Aristotle simultaneously endorses. (shrink)

Aristotle analyses a large range of objects as composites of matter and form. But how exactly should we understand the relation between the matter and form of a composite? Some commentators have argued that forms themselves are somehow material, that is, forms are impure. Others have denied that claim and argued for the purity of forms. In this paper, I develop a new purist interpretation of Metaphysics Z.10-11, a text central to the debate, which I call 'hierarchical purism'. I argue (...) that hierarchical purism can overcome the difficulties faced by previous versions of purism as well as by impurism. Roughly, on hierarchical purism, each composite can be considered and defined in two different ways: From the perspective of metaphysics, composites are considered only insofar as they have forms and defined purely formally. From the perspective of physics, composites are considered insofar as they have forms and matter and defined with reference to both. Moreover, while the metaphysical definition is a definition in the strict sense of 'definition', the physical definition is a definition in a loose sense. Analogous points hold for intelligible composites and geometry. Finally, neither sort of definitional practice implies that, for Aristotle, forms are impure. (shrink)

This essay is the first part of an analysis on the form and matter in the works of Aristotle. Within the whole analysis, I shall examine passages taken from different works of Aristotle that are relevant to the investigation on form and matter. In this essay, I shall focus exclusively on the chapter Metaphysics Zeta 3. The concepts of substance, matter, ontological subject, form, composite substance, this something and separated, which are consistently used by Aristotle within the development of the (...) mentioned chapter, will be part of my survey of the contents of the chapter. The central argument of Metaphysics Zeta 3, which maintains the equivalence between substance and the feature represented by ontological subject, and which leads, through this first equivalence and through the equivalence between matter and ontological subject, to the result that matter is (the only) substance, will be investigated step by step so that all presuppositions, entailments, and consequences of the argument itself can be clearly shown. The problems which are caused by the mentioned equivalence of substance and ontological subject will be pointed out during my look at the chapter’s contents. In particular, Aristotle cannot accept that, in spite of the ontological subject being a correct feature of substance qua substance, substance is therewith reduced to matter. Being the ontological subject does not represent the only ontological feature of substance qua substance; the ontological features too of substance qua substance that are represented by being a this something and being separated belong to the concept of substance: they can never be forgotten within a right interpretation of substance. The identification of substance only with matter can never be accepted. Only the ontological values of substance represented by the form and by the composite substance possess the ontological features “being a this something” and “being separated”. Therefore, the ontological values of substance as form and as a composite substance must always be reckoned with in a correctly interpreted ontology. Neither of these values can be forgotten within an accurate inquiry of ontology. Hence, regardless of whether matter is substance and is correctly interpreted as substance, the values of substance as form and as composite substance must belong, in Aristotle’s view, to any right ontological system whatsoever. The plurality of values for substance, which I personally advocate, finds confirmation thanks to chapter Metaphysics Zeta 3: Matter, form, and composite substance all represent values for substance, despite the differences which they have as regards their own ontological features.

La exposición y crítica de las doctrinas antiguas tiene un lugar importante en los escritos de Aristóteles. Sin embargo, ciertas dudas se han vuelto corrientes acerca de la confiabilidad de sus descripciones. Más aún, se ha sostenido que Aristóteles deforma la comprensión histórica a través de la introducción de conceptos y términos propios. En este libro se aborda el problema a través de un análisis de las críticas que Aristóteles dirige a la teoría platónica de las Ideas, que permite explicar (...) la constitución y desarrollo de importantes conceptos aristotélicos a partir de la confrontación dialéctica con las doctrinas de su maestro. En efecto, las dificultades genuinas que Aristóteles descubre en el platonismo constituyen el motor para gestar nuevos conceptos, que no son ajenos, sino que surgen como implicaciones del examen crítico. Así, la imposición de términos propios no debe interpretarse como distorsión, sino como el modo que Aristóteles adopta para exhibir su particular solución a los problemas que los filósofos anteriores dejaron sin solución.

In these pages the author intends to examine the idea, quite widespread among Aristotle’s recent scholars, that the method of metaphysics were mainly dialectical. This problem is investigated in Aquinas, who decidedly denies that metaphysics uses dialectics because it just provides probability. Metaphysics, unlike dialectics, is not only based on the being of reason but also on the natural being. Therefore, it does not simply constitute a rational game about quiddities, but it studies things in their real actuality and must (...) therefore be supported by evidence. Although Aquinas agrees with Aristotle in affirming that not every science enjoys the same certainty, this fact is due to different reasons. First, all things do not possess the same stability and constancy. Secondly, there is not always a perfect match between the studied matter and the human faculty to ascertain. This match between the object and the subject is the most decisive factor for the certainty of sciences. (shrink)

Theophrastus' treatise "Metaphysics" contains a compact and critical reconstruction of unsolved systematic problems of classical Greek philosophy. It is primarily about fundamental problems of ontology and natural philosophy, such as the question of the interdependence of principles and perceptible phenomena or the plausibility of teleology as a methodical principle of the explanation of nature. The aim of the critical Greek-German edition (with introduction and commentary) is to make visible the systematic significance of Theophrastus' critique of metaphysics.

This essay contains an attempt to trace the evolution of the concept of wisdom as found in the thought of Aristotle and Aquinas in terms of how the philosophical concept of wisdom as an intellectual virtue is understood and used to express the theological concept of wisdom as a gift of the Holy Spirit. The main aim is to understand how Aquinas derived the concept of wisdom from Aristotle's metaphysics and developed it in his mysticism. This research is based on (...) a close study of Book Six of Aristotle's Nichomachean Ethics, the corresponding sections of Aquinas' Sententia libri Ethicorum and question forty-five of the second part of the second part of Aquinas' Summa Theologiae. The insights gained from the study are then used to decipher the theoretical meaning of Augustine's famous saying: "love and do what thou wilt" and to expound on the practical value of wisdom for religious leaders.

Based on the notion of proem as exposed in Aristotle’s Rhetoric, we examine in detail Metaph. A1. Our goal is to understand the argument contained in this chapter, as we also endeavour to show how the Stagirite introduces with uttermost caution the theme of wisdom [σοφία], that which is the incarnation of the preeminent science in the first book of the Metaphysics. The attention we devote to the proem of this work is explained by the importance we attribute, unlike much (...) of contemporary scholars, to σοφία, that is, the science of first causes and principles, which we consider to be, ultimately, the pivotal formulation of the supreme science in the Metaphysics.

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