This 1999 book demonstrates a method for reading the texts of Aristotle by revealing a continuous line of argument running from the Physics to De Caelo. The author analyses a group of arguments that are almost always treated in isolation from one another, and reveals their elegance and coherence. She concludes by asking why these arguments remain interesting even though we now believe they are absolutely wrong and have been replaced by better ones. The book establishes the case that we (...) must rethink our approach to Aristotle's physical science and Aristotelian texts, and as such will provoke debate and stimulate new thinking amongst philosophers, classicists, and historians of science.

Aristotle's use of the phrase τὰ καλούμενα στοιχεȋα is usually taken as evidence that he does not really think that the things to which this phrase refers, namely, fire, air, water, and earth, are genuine elements. In this paper I question the linguistic and textual grounds for taking the phrase τὰ καλούμενα στοιχεȋα in this way. I offer a detailed examination of the significance of the phrase, and in particular I compare Aristotle's general use of the Greek (...) participle καλούμενος (-η, -ον) in other contexts. I conclude that his use of the phrase τὰ καλούμενα στοιχεȋα does not carry ironical or sceptical connotations, and that it ought to be understood as a neutral report of a contemporary opinion that the elements of bodies are fire, air, water, and earth. I leave aside the question as to whether or not Aristotle himself endorses this opinion. (shrink)

The author claims that parts of the De Caelo comprise a distinct work of Aristotle and can be taken as an early composition, earlier than the De Philosophia. The book is a careful philological and philosophical analysis of this text, and takes a position in regard to the authors who have commented on it. The doctrine of the text is contrasted to Plato’s cosmology, especially concerning the concepts of physics and aether. The text is also compared to Aristotle’s later teaching (...) and many differences are noted: hylomorphism, entelechy, and the unmoved mover, are conspicuously absent. Besides analyzing the relevant parts of De Caelo, the author has remarks about such works as the Protreptic, De Philosophia, and Physics I and II.—R.S. (shrink)

A connection between Aristotle's syllogistic and the calculus of relations is investigated. Aristotle's and Gergonne's syllogistics are considered as some algebraic structures. It is proved that Gergonne's syllogistic is isomorphic to closed elements algebra of a proper approximation relation algebra. This isomorphism permits to evaluate Gergonne's syllogisms and also Aristotle's syllogisms, laws of conversion and relations in the "square of oppositions" by means of regular computations with Boolean matrices.

Aristotle's Categories can easily seem to be a statement of a naïve, pre-philosophical ontology, centered around ordinary items. Wolfgang-Rainer Mann argues that the treatise, in fact, presents a revolutionary metaphysical picture, one Aristotle arrives at by (implicitly) criticizing Plato and Plato's strange counterparts, the "Late-Learners" of the Sophist. As Mann shows, the Categories reflects Aristotle's discovery that ordinary items are things (objects with properties). Put most starkly, Mann contends that there were no things before Aristotle. The author's argument (...) consists of two main elements. First, a careful investigation of Plato which aims to make sense of the odd-sounding suggestion that things do not show up as things in his ontology. Secondly, an exposition of the theoretical apparatus Aristotle introduces in the Categories--an exposition which shows how Plato's and the Late-Learners' metaphysical pictures cannot help but seem inadequate in light of that apparatus. In doing so, Mann reveals that Aristotle's conception of things--now so engrained in Western thought as to seem a natural expression of common sense--was really a hard-won philosophical achievement. Clear, subtle, and rigorously argued, The Discovery of Things will reshape our understanding of some of Aristotle's--and Plato's--most basic ideas. (shrink)

Twenty-five years ago Paul Wilpert called for a thorough re-examination of our knowledge of the content of Aristotle's lost workDe Philosophia. Expressing his reservations about the validity of our current reconstruction of the work, he wrote: ‘On the basis of attested fragments, we form for ourselves a picture of the content of a lost writing, and this picture in turn serves to interpret new fragments as echoes of that writing. So our joy over the swift growth of our collection (...) of fragments is clouded by the thought that we are not thereby really nearing the original character of the work, but we are entangling ourselves ever more tightly in a picture we ourselves have created.’ As a corrective Wilpert called for a critical retracing of our steps since 1830 to establish a more secure reconstruction of this important lost work.Since then there have been numerous, searching analyses of the ideas and fragments ofDe Philosophia, but at least one venerable old theory has escaped critical reappraisal: namely, the theory that inDe PhilosophiaAristotle discussed his doctrine of a fifth element, i.e. his belief that the heavenly bodies are composed of an element distinct from the four earthly elements, earth, water, air, and fire. This theory has become so widely accepted that it has virtually become a fact. When support is needed, most modern authors simply cite one or both of the two modern authorities on the early Aristotle, namely W. Jaeger and E. Bignone. The more meticulous restate the traditional evidence with complete confidence that this evidence proves their case. If Wilpert's hope for a firmly grounded reconstruction of theDe Philosophiais ever to be achieved, one of the importantdesideratatoday is a critical re-examination of the evidence for the fifth element in this work.

The present paper discusses Grosseteste’s reception of Proclus’ Elements of Physics (EP) in his Commentary on Aristotle’s Physics VI. In the first section I examine the method with which Grosseteste reconstructs Aristotelian texts. The second section initiates a study of the way Grosseteste evaluates Proclus’ EP on the basis of this method. Thus, the third section brings out Grosseteste’s moderate criticism of Proclus’ treatment of certain Aristotelian conclusiones and assumptions. The fourth section extends this study to the conceptual relation (...) between contiguity, continuity and succession. Finally, Grosseteste’s evaluation of Proclus’ tendency to omit, divide and merge Aristotelian conclusiones is studied in the fifth section. I conclude that Grosseteste is a careful and moderately critical reader of Proclus. He aptly grasps the dependence of the EP on Physics VI and conceives of Proclus’ EP as a forerunner of his own method of reconstructing Aristotelian texts. (shrink)

The paper investigates Aristotle's simulation of the embryo (zygote) by a gear wheel mechanism. By this technical simulation of a natural thing Aristotle pursues an epistemic end, viz. to gain information on the efficient cause of embryonal development. Aristotle verifies the conjectured, yet unknown efficient cause of this natural process by means of a distinctive mapping of the artifact onto the embryo. The paper aims to show that Aristotle, to achieve this verification, tackles a calculus of relations with a (...) semantics of causal content, providing logicocausal deductions, an ancient causal analogue of the truth-preserving calculus of relations. The elements of this Aristotelian causal calculus are those relations among the components of composite things that Aristotle holds to be causal. To these causal relations he applies various operations, set extension and set restriction, substitution, generalization and particularization, in such a way that the causal content of the relations transformed is preserved, thus affording deductions of relations from relations that are valid in respect to their causal content. The paper finally aims to show that causal calculus, working well when applied to the gear wheel mechanism and the embryo, is not sound in every application. (shrink)

Although Aristotle's contribution to biology has long been recognized, there are many philosophers and historians of science who still hold that he was the great delayer of natural science, calling him the man who held up the Scientific Revolution by two thousand years. They argue that Aristotle never considered the nature of matter as such or the changes that perceptible objects undergo simply as physical objects; he only thought about the many different, specific natures found in perceptible objects. Against (...) this view, this book argues that Aristotle offers a systematic account of matter, motion, and the basic causal powers found in all physical objects. It argues that Aristotle not only sees all perceptible objects as sharing certain basic physical properties, but he also holds that perceptible objects have these physical properties because they are ultimately made from physical matter of one kind or another. Finally, it argues that for Aristotle the basic properties of matter, including the basic properties of the material elements, cannot be understood teleologically. (shrink)

Aristotle is a political scientist and a student of biology. Political science, in his view, is concerned with the human good and thus it includes the study of ethics. He approaches many subjects from the perspective of both political science and biology: the virtues, the function of humans, and the political nature of humans. In light of the overlap between the two disciplines, I look at whether or not Aristotle’s views in biology influence or explain some of his theses in (...) political science. I show that we should not seek a unified answer to this question, for the relationship between the two disciplines varies depending on the topic. In some cases, e.g. the nature of the human function, the biological background is likely to be endorsed as one of the presuppositions of the ethical enquiry. In other cases, e.g. the study of social hierarchies, even though the ethical works and the biological works come to similar conclusions, it is hard to establish that the biological approach is intended to provide support to the ethico-political approach. In conclusion, I show that Aristotle’s political science and his biology are in conflict at least in two important cases: his account of justice towards non-human animals and his exhortation to contemplate.

Chapter I: The background to Aristotle's theory is provided by Aristophanes' Clouds in the debate between the traditionalists and Socratics on moral education. Aristotle steers a middle course between the old and new educations, preserving on the one hand, the role of filial ties in the transmission of values, and on the other, the importance of practical reason in providing a critical assessment of attachments. ;Chapter II: Here I argue against a common reading of Aristotle that views moral training (...) as merely a matter of habituation and practice whereby certain skills become second-nature. I propose instead that moral training is a training of "right pleasures and pains", or attachments to certain ends and objects of value. These I argue are transmitted through antecedent attachments to family. ;Chapter III: A theory of the development of character requires an analysis of emotions and desires constitutive of character. Aristotle regards emotions as intentional, where by intentional he means directed at certain objects regarded by an agent selectively, as the result of certain beliefs, perceptions, and phantasia. Thus, emotions have desiderative and cognitive elements, and training is directed at each. ;Chapter IV: Another aspect of moral training is paideia through music and tragedy. Both ensure for the transmission of a common core of cultural values, and thus extend training beyond the family to the city. At the heart of this paideia is the notion of mimesis. In music, mimesis is a process is one of association, whereby the pleasurable quality of music reinforces an attachment to the characters which music expresses. In tragedy, the identification is more complex. Katharsis through pity and fear requires that we identify not merely with characters, but with choice and actions and deliberations which lead to them. ;Chapter V: I conclude by studying Aeschylus' Oresteia as a tragedy which illustrates the notion of identification, as well as Aristotle's general belief that moral training takes place within the family. Through tragedy we see the complexities that develop within philia, and are forced, through pity and fear, to examine our own filial sentiments and obligations. (shrink)

This Element is an examination of the philosophical themes presented in Aristotle's Nicomachean and Eudemian Ethics. Topics include happiness, the voluntary and choice, the doctrine of the mean, particular virtues of character and temperamental means, virtues of thought, akrasia, pleasure, friendship, and luck. Special attention has been paid to Aristotle's treatment of virtues of character and thought and their relation to happiness, the reason why Aristotle is the quintessential virtue ethicist. The virtues of character have not received the (...) attention they deserve in most discussions of the relationship between the two treatises. (shrink)

ANY SCHOLAR INVESTIGATING ARISTOTLE’S ACCOUNT of φρόνησις sooner or later encounters the question whether φρόνησις concerns means to the ends of human actions or those ends themselves. There is an abundance of literature, mostly French, on the topic; nevertheless, the question is worthy of reconsideration, because an element essential to answering the question, namely an understanding of the ends of human action or πρᾶξις, has not received adequate treatment in the literature to date. One reason for this oversight is that (...) Aristotle defines πρᾶξις as having its end in itself, in distinction from ποίησις which has its end in something external to itself. Hence, when Aristotle says in Nicomachean Ethics 3 that actions are for the sake of things other than themselves, scholars have tended to conclude that Aristotle is confusing moral action and poietic action in this passage. In addition, there is an ambiguity about the very notion of an end in the Nicomachean Ethics which has not been fully recognized and explained. It is clear from the beginning that happiness is the end of ethics; yet it is worthy of note that Aristotle speaks of ends both in the singular and in the plural. If πρᾶξις is a specific action in specific circumstances, and if, as Aristotle says, it has its end in itself, how are we to understand these ends, or this one end, happiness, as the end of a particular action? Could it be in fact the case that practical actions have ends other than themselves, as the passage from Nichomachean Ethics 3 suggests? Since Aristotle says that the principles of actions are their ends, is there one end which unifies moral activity? How can an indeterminate end such as happiness, the supreme good, be the real end of a specific action? To answer these questions we will need to explain, in a manner consistent with Aristotle’s other statements, how moral action has its end, how it can have an end other than itself, and what are the different perspectives in which things can be regarded as ends. We will then be in a better position to reconsider what it is that makes our actions moral and how the morality of our actions is related to φρόνησις in its role as the discerner of practical truth.

John Corcoran’s natural deduction system for Aristotle’s syllogistic is reconsidered.Though Corcoran is no doubt right in interpreting Aristotle as viewing syllogisms as arguments and in rejecting Lukasiewicz’s treatment in terms of conditional sentences, it is argued that Corcoran is wrong in thinking that the only alternative is to construe Barbara and Celarent as deduction rules in a natural deduction system.An alternative is presented that is technically more elegant and equally compatible with the texts.The abstract role assigned by tradition and Lukasiewicz (...) to Barbara and Celarent is retained.The two ‘ perfect syllogisms’ serve as ‘basic elements’ in the construction of an inductively defined set of valid syllogisms.The proposal departs from Lukasiewicz, and follows Corcoran, however, in construing the construction as one in natural deduction.The result is a sequent system with fewer rules and in which Barbara and Celarent serve as basic deductions.To compare the theory to Corcoran’s, his original is reformulated in current terms and generalized.It is shown to be equivalent to the proposed sequent system, and several variations are discussed.For all systems mentioned, a method of Henkin‐style completeness proofs is given that is more direct and intuitive than Corcoran’s original.

Aristotle's Meteorology is - after the theoretical works Physics and De Generatione et Corruptione - the first practical application on the evidence of the elements and their properties. The texts of the Arabic and Latin versions, the last of which is printed here for the first time, are presented together with an Introduction and Index.

Aristotle uses 'body' to describe the matter of animals, the elements and what they compose, as well as magnitudes extended in three-dimensions. These last bodies belong to the category of quantity, alongside surfaces and lines. It is this notion of body that interests Christian Pfeiffer, who presents Aristotle's various discussions of it as one exhaustive theory of body. According to this theory, magnitudes are form-matter composites, where boundaries are forms and extensions are matter. The boundary of a body (...) is its particular shape and its extension is its volume. It follows that Socrates destroys his body and gains another by standing up (since the shape of the sitting and standing bodies, and thus the bodies... (shrink)

In Aristotle's cosmology, the nature of the elements is defined by their place in the Totality. Their cosmic motions keep the whole in motion, and this is their nature. Thus, the cosmos is an organized whole, a single substance directed to the good; this body constitutes together with its Prime Mover a composite substance that can be regarded as a self-mover.

Fortunately, there is heat; and Freudenthal is keen to promote it as an overlooked central factor in Aristotle’s theory of material substance. He begins in agreement with the many scholars who argue that Aristotle’s theory of the four elements underdetermines the plain fact that there are organic substances which exhibit both synchronic and diachronic unity. He goes further than most, however, by arguing that left unaugmented Aristotle’s account of the four basic elements would positively preclude the existence of (...) these forms of unity. For Aristotle embraces the Presocratic picture of the four elements as engaged in “endemic strife”, so constituted that their natural propensities lead them to separate and dissolve rather than to unite and synthesize. Thus, for example, each of the four elements has a natural direction, which ought to result in fire and air ever moving upward and away from earth and water, which will move downward if unimpeded. Hence, as Aristotle himself recognizes, some agent force is required to hold the four elements together when they are mixed. (shrink)

By defending the following views – that Aristotle identifies the generator and perhaps the obstacle remover as an essential cause of the natural sublunary elemental motion in Physics VIII 4; that this view is consistent with the view of Physics II 1 that the sublunary simple bodies have a principle of internal motion; and that the sublunary and the celestial elements have a nature in the very same way – I shall offer what has so far eluded Aristotelian commentators: (...) a consistent interpretation of Aristotle's theory of the natural motions of the sublunary and also the celestial elements.

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.

Although thinkers before Aristotle saw rhetoric as a form of speech that helps to activate only emotions of audience, Aristotle mentions three different types of rhetoric as political, legal, and ceremonial, and structures the political rhetoric we examine in this research as an art consisting of three elements as subject, speaker, and audience, and three persuasion styles as reasoning, character of speaker, and emotional state of audience. As he structured it, political rhetoric is a reasoning-centered process. This reasoning centeredness (...) makes political rhetoric an art sensitive to public interest and virtue rather than individual interest. We claim that from this structuring it is possible to obtain important clues not only about what a reasonable political persuasion attempt should be like, but also about how to protect oneself from the manipulations of malicious politicians who try to manipulate the audience only with character impressions and emotional provocations in cases where reasoning and giving evidence are possible.

In a special issue of “Ethics and Information Technology” (September 2012), various philosophers have discussed the notion of online friendship. The preferred framework of analysis was Aristotle’s theory of friendship: it was argued that online friendships face many obstacles that hinder them from ever reaching the highest form of Aristotelian friendship. In this article I aim to offer a different perspective by critically analyzing the arguments these philosophers use against online friendship. I begin by isolating the most common arguments these (...) philosophers use against online friendship and proceed to debunk them one by one by pointing out inconsistencies and fallacies in their arguments and, where needed, offering empirical findings from media and communication studies that offer a more nuanced view on online friendships. I conclude my analysis by questioning the correctness of the application of the Aristotelian theory of friendship by the critics of online friendship: in my view, the critics are applying the Aristotelian theory to online friendships in a rather narrow and limited way. Finally, I conclude my thesis by proposing that in the rapidly changing online landscape, a one-size-fits-all application of the Aristotelian theory on friendship is not sufficient to accurately judge the multitude of relationships that can exist online and that the various positive and valuable elements of online friendships should also be acknowledged and analyzed.

Modern virtue ethics is commonly presented as an alternative to Kantian and utilitarian views—to ethics focused on action and obligations—and it invokes Aristotle as a predecessor. This paper argues that the Nichomachean Ethics does not represent virtue ethics thus conceived, because the discussion of the virtues of character there serves a quasi-Platonic psychology: it is an account of how to tame the unruly (non-rational) elements of the human soul so that they can be ruled by reason and the laws (...) it imposes. This is explicitly stated in Book X, where it is also affirmed that the question of which laws reason should impose is addressed in The Politics. The Ethics and Politics can therefore be seen as a unity—as Aristotle's version of Plato's Republic—and it is the failure to recognize this that explains Aristotle's misappropriation by the modern virtue ethicists.

Essentialists claim that at least some individuals or kinds have essences. This raises an important but little-discussed question: how do we come to know what the essence of something is? This paper examines Aristotle’s answer to this question. One influential interpretation (viz., the Explanationist Interpretation) is carefully expounded, criticized, and then refined. Particular attention is given to what Aristotle says about this issue in DA I.1, APo II.2, and APo II.8. It is argued that the epistemological claim put forward in (...) DA I.1 differs from that put forward in APo II.2 and II.8, contrary to what has been claimed by Explanationists, and that each of these distinct epistemological claims rests on a distinct non-epistemological thesis about essence. Consequently, an ‘Enriched Explanationist Interpretation’ is developed which takes into account both of the aforementioned elements in Aristotle’s epistemology of essence. The paper concludes by highlighting an insight the preceding exegetical discussion offers to contemporary essentialists seeking to explain how we come to know what something’s essence is. (shrink)

The concept of right or fit is an important element entailed, but not fully articulated, in the concept of action or practice in Aristotle's theory of virtue; which, however, turns to be of the utmost importance in later Western ethics. Right is concerned with both feelings and actions, and is not the same for all individuals. It lies in between the two extremes of the spectrum of practical affairs, yet by no means equidistant from them. This account of the (...) concept of fitness or right is derived from the categories of quantity, relationship, and quality rather than from that of substance. Thus, it seems that virtue is relative to vice or error within a continuous existence. If, however, the right of passion and action is environmental and concrete, is it multiple and not singular? To this question, Aristotle gives his reply on two levels: On the level of concrete practitioners, what is right and fit to one man might not be so to another man, and hence the right of practice is not singular but multiple; whereas on the level concerned with the only right choice compared with the two extremes or errors, the right of practice will always be singular. /// "正确"是隐含于亚里士多德的德性学说中的一个重要而未充分展开的，在 后来的西方伦理学中却变成极为重要的关于行为或实践的概念。"正确"与感情和 行为都相关。"正确"并不是对所有人同样的。它是两端间的那个中间，但井不始 终与两端距离相等。对适度或正确的这种说明基本上是从数量、关系与性质范畴引 出，而不是从实体范畴引出的述说。所以，德性似乎始终是在一种有连续性的存在 中相对于恶或错误而言的。感情与行为的正确如果是环境的、具体的，它是否是多 而不是一?亚里士多德在两个层面上回答这个问题。在相对于具体实践者的层面， 对我而言的适度或正确很可能不同于对你而言的，实践的正确不是一而是多:在相 对于两端或错误唯有一个正确的选择而言，实践的正确始终只是一。.

By a thorough study of the Posterior Analytics and related Aristotelian texts, Richard McKirahan reconstructs Aristotle's theory of episteme--science. The Posterior Analytics contains the first extensive treatment of the nature and structure of science in the history of philosophy, and McKirahan's aim is to interpret it sympathetically, following the lead of the text, rather than imposing contemporary frameworks on it. In addition to treating the theory as a whole, the author uses textual and philological as well as philosophical material (...) to interpret many important but difficult individual passages. A number of issues left obscure by the Aristotelian material are settled by reference to Euclid's geometrical practice in the Elements. To justify this use of Euclid, McKirahan makes a comparative analysis of fundamental features of Euclidian geometry with the corresponding elements of Aristotle's theory. Emerging from that discussion is a more precise and more complex picture of the relation between Aristotle's theory and Greek mathematics--a picture of mutual, rather than one-way, dependence.

This volume includes an element that is a departure in this series, the lengthy Introduction by Carlos Steel, which puts, in revised form, his article with F. Bossier, “Priscianus Lydus en de In de Anima van Pseudo-Simplicius,” Tijdschrift voor Filosofie 34 : 761–822. The editor’s decision to include this discussion of the author of the commentary on the soul is to be commended. An English version gives wider access to the carefully constructed argument of Steel and Bossier, and its placement (...) in this volume gives the reader the immediate opportunity to test the hypothesis by comparing the two different works, translated by Huby and Steel respectively. Huby, moreover, in her brief introduction and notes, highlights in an evenhanded way the pros and cons of the argument. She points out the possibility that the similarity of both works may indicate a common reliance on Iamblichus rather than the common authorship forcefully argued by Steel. At a minimum, however, Steel demonstrates that the author of the commentary cannot be Simplicius, with the attribution to Priscian somewhat more circumstantial. Finally, it is also quite delightful to find the Greek of the introduction untransliterated. It is much more useful for scholarly purposes, especially since the grounding of Steel’s argument in terms of Greek style and vocabulary cannot be decided by comparing the two translations. The reader must go back to the Greek text itself. (shrink)

This book offers an original new account of one of Aristotle's central doctrines. Freudenthal He recreates from Aristotle's writings a more complete theory of material substance which is able to explain the problematical areas of the way matter organizes itself and the persistence of matter, to show that the hitherto ignored concept of vital heat is as central in explaining material substance as soul or form.

This article will explore whether there are arguments for Aristotle's concept mixis which can aid our current discussions within the philosophy of chemistry.

The main aim of my paper is to analyse Aristotle’s theory of language in the context of his Physics I.1 and via an analysis and an interpretation of this part of his Physics I try to show that (i) the study of human language (logos) significantly falls within the competence of Aristotle’s physics (i.e. natural philosophy), (ii) we can find the results of such (physical) inquiry in Aristotle’s zoological writings, stated in the forms of the first principles, causes and (...) class='Hi'>elements of the human speech (logos) and (iii) the analogies (Phys. 184b13-14) made by Aristotle at the very end of the first chapter make better sense if we consider them in the broader context in which Aristotle recognizes language as a complex natural phenomenon we are born into and which has to be not only biologically, but also socially developed through our lives. Hence, I aim towards a more naturalistic reading of Aristotle’s views on language. (shrink)

One of the basic elements of Nicholas of Cusa's philosophy of mathematics is his theory of mathematical objects as “entities-of-reason” (entia rationis). He refers to these as being “abstracted from sensible things”. That is why it is possible to assume that Nicholas bases his theory of mathematics on Aristotle's philosophy of mathematics. Aristotle too describes mathematical objects as coming into being through abstraction (ex aphaireseos). The author analyses Cusa's understanding of abstraction in De docta ignorantia and De mente (...) and tries to show that – according to Nicholas of Cusa – the abstraction, which is ens rationis, simultaneously stimulates the human mind to produce mathematical objects from within itself. The author attempts to show how Cusa's philosophy of mathematics is not directly based on Aristotle's philosophy of mathematics – Aristotle is not an abstractionist and does not ascribe the existence of mathematical objects to the mind of the mathematician – but on the abstractionist interpretation of Aristotle by Alexander of Aphodisias, who was followed by the predominantly neoplatonist commentators of Aristotle. These commentators did not see any important differences in the metaphysical or epistemological underpinnings of abstractionism and the so-called projectionism, i.e. the theory according to which mathematical objects pre-exist in the soul.

This is a wonderful book. It is, in my opinion, the best book on Aristotle’s treatment of the physical world to appear in recent years. Still, this book is not one that can be read through on a Sunday afternoon. It resembles a text of Aristotle in the compactness of argument, though not, I am happy to report, in clarity. Like a guide raised in the wild, Lang leads us through a large sector of the forest of arguments in the (...) Physics and De Caelo. This analogy brings me to the following point: Lang’s perspective on Aristotle is extraordinary. Lang is the author of another excellent book, Aristotle’s Physics and Its Medieval Varieties. Discussions of Aristotle’s philosophy of nature through the lens of medieval philosophy and science are not uncommon. These discussions, however, face the peril of attributing, in one way or another, viewpoints to Aristotle that are actually those of his medieval successors. For this reason most work on Aristotle is now done without reference to medieval thought. Perhaps this is as it should be. But one of the great difficulties in understanding Aristotle’s conception of the world is how we are to interpret what he says. Our perspective on the world is largely formed on the basis of early modern rejections of medieval Aristotelian views. That is to say that built into our perspective is a negative response not to Aristotle directly but to medieval interpretation of Aristotle. This fact makes it extremely difficult for us to see Aristotle clearly. Here lies the advantage of knowing the “medieval varieties” of Aristotle’s natural philosophy when we try to make sense of Aristotle. Knowing this helps us distinguish more clearly between our own perspective and its roots and Aristotle’s. Aristotle’s perspective is in fact fundamentally different from ours. For example, Lang points out that to insert the notion of “speed” into Aristotle’s discussion of motion is “seriously misleading” because speed is conceptually distinguishable from moving bodies and is so treated, whereas motion, for Aristotle, is always the actualization of a capacity intrinsic to a moved body; therefore motion can neither be quantified nor abstracted from what is moved.

The paper proposes a novel understanding of how Aristotle’s theoretical works complement each other in such a way as to form a genuine system, and this with the immediate (and ostensibly central) aim of addressing a longstanding question regarding Aristotle’s ‘first philosophy’—namely, is Aristotle’s first philosophy a contribution to theology, or to the science of being in general? Aristotle himself seems to suggest that it is in some ways both, but how this can be is a very difficult question. My (...) answer is in some respects a version of one that goes back at least to the middle ages—i.e., that first philosophy is concerned with the gods (and to that extent offers a theology) because the gods are causes and principles of beings precisely insofar as they are beings. The more original aspect of my position lies in my claim that the sort of tension found in the Metaphysics is likewise to be found in many of Aristotle’s physical works. Thus, for example, the De caelo is (I argue) concerned generally with natural beings (= beings susceptible of change), but its discussions are focused largely on the heavenly bodies and the Aristotelian elements insofar as they admit of change with respect to place. Here I claim that the particular objects of discussion are dealt with precisely because they are causes and principles of natural beings as such. Something similar goes, I claim, for the De generatione et corruptione, the general concern of which is a particular species of natural being—i.e., natural beings susceptible of generation and corruption. In this way, I argue, Aristotle successively deals in his theoretical works with those causes and principles of (say) a horse which attach to it insofar as it is a being, those causes and principles of a horse which attach to it insofar as it is a natural being, those causes and principles of a horse which attach to it insofar as it is a perishable natural being, and so on for the lower genera under which the species horse is subsumed.

Given that they are chance events, there can be no scientific demonstration or knowledge of monsters. There are still, however, many recognizable elements of scientific explanation in Aristotle's Generation of Animals Book IV chapter 4. What happens in cases of monsters and deformities occurs in the process of generation, and there is much that we can know scientifically about this process—working from the animal’s essential attributes outward to factors that influence these processes. In particular, we find Aristotle looking (...) for and investigating whether “for the most part” correlations are causally relevant and linked to essence. Even though the birth of monsters is scientifically inexplicable, the features of animals that tend to produce them can be known about. I will explain how it is that producing more than one offspring per birth is a knowable feature of a kind. This feature, along with others, can then give us a much better grasp on what happens in particular instances of monstrous birth. (shrink)

Commentators have often held that aristotle's general doctrine of change commits him to a persisting material substrate for every change, And to an indeterminate material substrate (prime matter) for elemental transformation. I argue that though aristotle accepts a common matter for the four elements, Both these claims are false.

This article is primarily concerned with Aristotle’s theory of the syllogistic, and the investigation of the hypothesis that logical symbolism and methodology were in these early stages of a geometrical nature; with the gradual algebraization that occurred historically being one of the main reasons that some of the earlier passages on logic may often appear enigmatic. The article begins with a brief introduction that underlines the importance of geometric thought in ancient Greek science, and continues with a short exposition of (...) Aristotle’s views and methods in regard to logic. We then offer an interpretation of syllogisms, as well as of the main proof methods that are utilized by Aristotle, in terms of diagrams that can be seen as analogous to those of Euclidean geometry; where the various proofs proceed by appropriately manipulating an initially drawn diagram, in a way parallel to constructions that occur in Euclid’s Elements. In this way, logic is presented as following, to a large degree, methodological tenets established by the practice of geometry. Finally, we present a diagrammatic decision procedure that allows one to directly read off the validity of syllogisms from a corresponding diagram, in a way such that no further manipulation of it is necessitated.
