Michael Wedin argues against the prevailing notion that Aristotle's views on the nature of reality are fundamentally inconsistent. According to Wedin's new interpretation, the difference between the early theory of the Categories and the later theory of the Metaphysics reflects the fact that Aristotle is engaged in quite different projects in the two works--the earlier focusing on ontology, and the later on explanation.

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 39.3 (2001) 437-438 [Access article in PDF] Michael V. Wedin. Aristotle's Theory of Substance: The Categories and Metaphysics Zeta. Oxford Aristotle Studies. New York: Oxford University Press, 2000. Pp. xiii + 482. Cloth, $55.00. Michael Wedin has written the equivalent for Aristotle of what biblical scholars would call a "harmony of the gospels." It is a wonderfully rich and argumentatively (...) dense reconstruction of Aristotle's two most important treatises on substance, the Categories and Metaphysics Zeta, works that many of our most able Aristotle scholars have declared irreconcilable.The first chapter, on "the plan" of the Categories, includes a sensible account of the role in that work of the "onymies," as Wedin calls homonymy, synonymy, and paronymy. The second chapter, which focuses on "nonsubstantial individuals" in the Categories, gives the most philosophically sophisticated reconstruction known to me of how Aristotle might have conceived this white in Socrates to be a nonrecurrent particular. Having myself contributed to the glut of recent scholarship on nonsubstantial individuals in the Categories, I have personal, as well as professional, reasons to praise the rigor and insight of this chapter.In Chapter 3 Wedin tries to pin down the ontological commitment of Aristotle's Categories. Since, if there were no primary substances there would not be anything else, the fundamental ontological commitment of the Categories is a commitment to primary substances. Individual nonsubstances exist just in case there are primary substances in which they inhere. As for species and genera of substances and species and genera of the nonsubstantial individuals that inhere in them, Wedin finds Aristotle curiously indifferent to their existence.Chapter 4, a transitional chapter, takes up a range of possible views on the relation between the Categories and Metaphysics Zeta. Incompatibilism is argued against, yet the arguments for compatibilism in recent commentaries are found to be insufficient. In the next chapter Wedin moves on to his own statement of, and justification for, compatibilism.The key to Wedin's compatibilist interpretation is the distinction he draws between being a substance and being the "substance-of" something. Zeta can then be seen to be supplementing, rather than revising, let alone contradicting, the Categories, if Zeta can be understood to be about the substance-of the primary substances of the Categories (157-8).Aristotle proposes in Z3 three candidates for what the substance of, say, Socrates, is, namely, his matter, his form, and the compound of the two. Aristotle settles on form and discusses form as essence in Z4 and Z5, which discussion Wedin takes up in his own [End Page 437] Chapter 6. Then in Chapter 7 Wedin takes on the enigmatic claim of Z6, "In the case of things that are primary and spoken of per se, it is clear that the thing and the essence of the thing are the same" (1032a4-6).Wedin makes Chapter 8, which is primarily a treatment of Z10 and Z11, a discussion of Aristotle on "compositional plasticity," that is, on whether, say, the form of human being might be realized in something other than flesh and bones. "[O]ne could grant," Wedin writes, that to be a human being is just to be a member of a determinate biological species and so to have a very specific material nature, and yet insist that the form of such creatures be realizable in quite different sorts of matter. Creatures so constituted would not be human beings but they would be entities with similar functional capacities and states... From the point of view of philosophy of mind, for example, what matters are the psychological capacities, functions, and states characteristic of persons. Just what these are is determined by a form—the form that happens to be realized in human matter. (340-41) In Chapter 9 Wedin turns to Z13, which, as he acknowledges, has often been thought to be the most confounding chapter in Zeta. Wedin draws on Z16 to help resolve the aporia with which Z13 ends (roughly this... (shrink)

Aristotle's views on the fundamental nature of reality are usually taken to be inconsistent. The two main sources for these views are the Categories and the central books of the Metaphysics, particularly book Zeta. In the early theory of the Categories the basic entities of the world are concrete objects such as Socrates: Aristotle calls them 'primary substances'. But the later theory awards this title to the forms of concrete objects. Michael Wedin proposes a compatibilist solution to (...) this long-standing puzzle, arguing that Aristotle is engaged in quite different projects in the two works. The theory of Metaphysics Zeta is meant to explain central features of the standing doctrine of the Categories, and so presupposes the essential truth of the early theory. The Categories offers a theory of underlying ontological configurations, while book Zeta gives form the status of primary substance because it is primarily the form of a concrete object that explains its nature, and this form is the substance of the object. So when the late theory identifies primary substance with form, it appeals to an explanatory primacy that is quite distinct from the ontological primacy that dominates the Categories. Wedin's new interpretation thus allows us to see the two treatises as complementing each other: they are parts of a unified history of substance. (shrink)

The central question in Aristotle' Metaphysics Zeta- Eta is "What is substance?" and Aristotle answers that substance is essence or substantial form. But it is not clear what in Zeta-Eta Aristotle is inquiring and what the conclusion implies. ;In this study I argue that in Zeta-Eta Aristotle advances a new theory of substance: he establishes a new criterion for substance and identifies substantial form as primary substance. ;The criteria for substance which I take (...) Aristotle to offer are these two. A thing is a substance if and only if its formula of essence is a definition. A thing is a substance if and only if it has no cause other than itself. The former criterion is derived from a consideration of essence and substance from the formulaic point of view, while the latter is derived from a consideration of essence and substance from the metaphysical point of view. ;However, Aristotle recognizes a problem in the logical or formulaic criterion. The difficulty is that the definition of substantial form doesn't seem to be different from the definition of a concrete particular in the composite structure of the formula. The definitions of substantial form and a concrete particular are all composed of parts. I claim that such dissatisfaction with the logical criterion is the main reason why Aristotle declares a new beginning in Zeta 17. ;In Zeta 17 Aristotle claims that it is impossible to identify the cause of the being of substantial form in the same way as the cause of the being of a concrete particular, since the thing asked about is ontologically simple. The cause of the being of a simple thing is itself. Aristotle claims that substantial form, which is the cause of the being of a concrete particular, does not have any cause other than itself. Substantial form is, therefore, primary substance on the metaphysical criterion. ;This interpretation implies that a concrete particular is not to be ranked as primary substance and that this revision can be taken as "a return to, or a renewal of sympathy with, Plato" as G. E. L. Owen described. (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.

Significant scholarship has been devoted to the problem of the incompatibility of Aristotle’s accounts of substance in the Categories and in the Metaphysics. Substance, in the former treatise, is that category of being distinguished from the other accidental categories by reason of the ontological dependence of accident upon substance: every accident must be present in a substance to be present at all. Primary substances such as “Socrates” are distinguished from secondary substances such as “human being” or (...) “animal” since secondary substances are said of primary ones. Only primary substances are neither said of a subject nor present in a subject, depending upon nothing else for their existence. This assertion of the ontological primacy of the individual seems to be withdrawn by Aristotle, however, in the Metaphysics, in which substance emerges in a discussion of the hupokeimenon—the underlying subject of which everything else is predicated. This subject is to be understood in three senses: as matter, as form, and as the composite of the two. Primary substance, finally, is granted to form alone, the “most perplexing” of the candidates, according to Aristotle, and the one that turns out to refer to the same thing as essence. Since what Aristotle means by essence looks to be a form common to all individuals of a particular species, it is not surprising that commentators identify at worst a contradictory theory regarding substance, and at best a transformation of an immature theory of substance into a mature one.

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)

Aristotle's doctrines about accidental predication, Accidental identity, Etc., Can be understood as an attempt to state the same view as russell put forward in his theory of descriptions. "a" is predicated accidentally of b when "a to b" has the sense "something that is a is b." this permits scope distinctions which can solve puzzles like that of the masked man, And sophisms involving tense. Aristotle's claim that accidental being is akin to nonexistence resembles russell's account of (...) the present king of france as a logical fiction. (shrink)

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

Christian Pfeiffer explores an important, but neglected topic in Aristotle's theoretical philosophy: the theory of bodies. A body is a three-dimensionally extended and continuous magnitude bounded by surfaces. This notion is distinct from the notion of a perceptible or physical substance. Substances have bodies, that is to say, they are extended, their parts are continuous with each other and they have boundaries, which demarcate them from their surroundings. Pfeiffer argues that body, thus understood, has a pivotal role (...) in Aristotle's natural philosophy. A theory of body is a presupposed in, e.g., Aristotle's account of the infinite, place, or action and passion, because their being bodies explains why things have a location or how they can act upon each other. The notion of body can be ranked among the central concepts for natural science which are discussed in Physics III-IV. (shrink)

Today, there are many natural sciences, one of which is physics, but there is no science in the sense of a Theory of Nature. In our everyday life, the opinion is rightly held that there is only one nature, but whether this opinion stands up to reflection is questionable. When we apply the speculation that Aristotle developed in Metaphysics Λ to his Physics, we will see, that Aristotle has developed a Theory of Nature that consists in posing the (...) question of the being of the natural being (Frage nach dem Sein des Naturseienden). The standardinterpretation wants us to believe that Aristotle founded a substance metaphysics with a corresponding theology, and that he practised natural science. But, our hermeneutical situation could lead us to an "Aristotle today" and free us from old beliefs so that we, like Thomas Aquinas and others, could learn from a contemporary Aristotle as an immediate interlocutor. One of the learning points, for example, would be that questions are more crucial than new assertions, even if they are sophisticated, and that unassertive thinking (unbehauptendes Denken) in a topical attitude can lead us to insight into the multiplicity of worlds. This insight would have immediate consequences for our behaviour towards our co-inhabitants of our planet and towards our environment. (shrink)

The introduction to this book begins with the claim that it will provide new perspectives on the relationships between form and matter in Aristotle's thought, identifying as a point of departure the "basic level" where they interact, namely, in the coming-to-be of composite material substances, notably living things, and in their stable persistence, both at the level of the individual and of the species. Central to this interaction, it is claimed, is vital heat, the significance of which has not (...) been fully appreciated. Aristotle nowhere offers a systematic theory of vital heat, but the author attempts to recover such a thing from scattered discussions; in so doing, he argues for its unitary explanatory role in relation to all the soul's functions, makes some suggestions concerning its origin in Presocratic thought, and suggests its likely provenance in Aristotle's early theological cosmology.

Aristotle's criticism of Platonic Forms in the Metaphysics has been a major source for the understanding and developments of the theory of Forms in later Antiquity. One of the cases in point is Aristotle's argument, in Metaphysics I 9, 990b22-991a2, against Forms of non-substances. In this paper, I will first provide a careful analysis of this passage. Next, I will discuss how the argument has been interpreted - and refuted - by the fifth-century Neoplatonists Syrianus and Proclus. (...) This interpretation has played an important role in the broader context of the Neoplatonic debates on the range of Plato's theory of Forms, which was one of the traditional problems discussed about the Forms in later Platonism.

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。.

The present paper argues that Burnyeat's view is fundamentally correct, but approaches the issues from a somewhat different angle. The claim that forAristotle the form and the matter are non-contingently related is an allusion to Aristotle's difficult doctrine of the unity of substances. The functionalist interpretation underestimates Aristotle's doctrine of the unity of substance. Irwin thinks that Aristotle's view is a version of functionalism but acknowledges that his claims go beyond what is normally associated with functionalism. (...) But Irwin too fails to take sufficient account of his own acknowledgement of the importance of the unity of substance doctrine. The proper appraisal of the functionalist interpretation cannot, therefore, avoid the "abyss" of the Metaphysics. (shrink)

The Twofold Exhalation. Aristotle explains in Book I of the Meteorologica that the heat of the sun causes the earth to give off an exhalation , which is of two kinds. One kind, derived from the moisture within the earth and on its surface, is a moist vapour , ‘potentially like water’ ; the other, which comes from the earth itself, is hot, dry, and smoky, highly combustible ‘like a fuel’ , ‘the most inflammable of substances’ , ‘potentially like fire’ (...) , and compounded of Air and Earth.

L’identité et la datation de Nicolas le Péripatéticien, l’auteur d’un sommaire de la philosophie d’Aristote, ont fait l’objet d’un article récent de Silvia Fazzo paru dans la Revue des Études Grecques. Contre la datation courante, fondée sur l’identification de Nicolas à l’historien de grand renom Nicolas Damascène , Fazzo a montré que Nicolas avait probablement vécu au cours de la période couvrant les IIIe au Ve siècles ap. J.-C., et plus problablement à l’époque de l’empereur Julien l’Apostat . Cette hypothèse (...) trouve un appui dans un nouveau fragment en traduction hébraïque découvert par Mauro Zonta, dans lequel Nicolas cherche à expliquer la Trinité de Dieu au moyen de la doctrine aristotélicienne des causes: Dieu est un, en tant que sa substance est une, mais Dieu est également trois, puisqu’il est à la fois causes motrice, formelle et finale du monde. Dans la mesure, évidemment réduite, où un fragment si court est susceptible de datation, l’époque de Julien paraît la plus probable. (shrink)

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

The strongest version of the principle of the Identity of Indiscernibles states that of necessity, there are no distinct things with all their universals in common (where such putative haecceities as being Aristotle do not count as universals: I use 'universal' rather than 'property' here and in what follows for the simple reason that 'universal' is the term of art that most safely excludes haecceities from its instances). It is commonly supposed that Max Black's famous paper 'The identity of indiscernibles' (...) (2) refutes this thesis. (Armstong's [1], chapter 9 is representative here.) Black argues ([2], p. 156) that it is perfectly possible that there be a world consisting solely of two indiscernible spheres at some distance to each other and that this world constitutes a counterexample to the principle above. The strongest version of the bundle theory of substance claims that of necessity, the substances that make up the world are bundles of universals.1 It is commonly supposed that a consequence of Black's defeat of the principle of the Identity of Indiscernibles is that this bundle theory of substance is mistaken. (Again, Armstong's [1] is representative.) I shall argue that Black's thought experiment does not defeat the bundle theory and that, as a result, the bundle theory can be used to salvage the principle of the Identity of Indiscernibles.

In his doctoral dissertation Von der mannigfachen Bedeutung des Seienden nach Aristoteles Brentano tried to show that (against criticism of this) one could indeed give a principle defense of Aristotle's table of categories as a coherent system. In later texts Brentano appears sharply critical of Aristotle, mainly in respect to Aristotle's mereology, or theory of part and whole, and to his theory of substance and accident. It is argued that Brentano hadn't observed that Aristotle's (...) belief that there are as many predicative senses of 'be' as there are categories of being is based not on his mereology but on his theory of definition. Overlooking this Brentano was led to far reaching inadequate ontological consequences. (shrink)

Aristotle argues that the soul and body are non-identical substances; the soul is an immaterial particular form, while the body is a diachronic material continuant. Despite their immateriality, Aristotle argues that souls are not separable from bodies, and so implicitly rejects any version of Cartesian dualism. But because of his commitment to immaterialism, Aristotle's position cannot be assimilated to any contemporary materialist theory in the philosophy of mind. We need not, however, regard him as inconsistent in rejecting both (...) Cartesian dualism and materialism: Aristotle rightly recognizes that the soul can be a substantial immaterial particular form which supervenes on the body. Aristotle is, then, a supervenient dualist, who holds that there are nomological relations between physical and psychic states, but who denies that psychic states are token identical with material states. ;But Aristotle notoriously does not regard the supervenience of the soul as sufficient for the supervenience of each of its capacities. He provides an interesting but unsuccessful a priori argument for the claim that nous, or mind, is a capacity of the soul which does not supervene on any bodily state. Thus, he concludes that nous can survive the destruction of the body; but post mortem survival of nous need not be regarded as sufficient for a commitment to post mortem personal identity in Aristotle.

Aristotle’s philosophy is considered with respect to one central concept of his philosophy, viz. opposition. Far from being a mere side-effect of syllogistic, it is argued in the present paper that opposition helps to articulate ontology and logic through an account of what can be or cannot be in a systematic and structural way. The paper is divided into three main parts. In Section I, the notion of Being is scrutinized through Aristotle’s theory of categories. In Section II, the (...) notion of Non-Being is connected to Aristotle’s theory of oppositions. In Section III, the notion of essence is revisited in order to bring about a holist theory of meaning by individuating through opposite properties. In conclusion, the legacy of Aristotle is depicted as balanced between a powerful reflection around Being and a restrictive ontology of substance. (shrink)

Aristotle’s theory of seed has occupied a very important place in the history of ancient embryology and medicine. Previous studies have overemphasized, in light of the APo. II method, Aristotle’s definition of seed as male semen. In this paper, I wish to show that there are at least three independent definitions of seed working in Aristotle’s Generation of Animals: seed as male semen, seed as female menstruation and seed as embryo. Those three definitions are mutually exclusive on the one (...) hand, but on the other hand, they are also capable of being unified into one Aristotelian account, which can help us understand better Aristotle’s theory of seed.

This paper is a study of Brentano’s ontology, and more specifically of his theory of substance and accident as put forward toward the end of his life in the materials collected together as the Kategorienlehre or Theory of Categories. Here Brentano presents an auditious (re-)interpretation of Aristotle’s theory of substance and accidence. We show that on the view Brentano initially defends, it is space which serves as the single substance upon which all other entities (...) depend as accidents. In an appendix, however, Brentano puts forward an even more radical suggestion, inspired by the physics of Kelvin. According to this final view, space itself is an accident of a deeper substance: the present time. (shrink)

This book claims that Aristotle followed an aspect theory of predication.

Substance and Essence in Aristotle is a close study of Aristotle's most profound—and perplexing—treatise: Books VII-IX of the Metaphysics. These central books, which focus on the nature of substance, have gained a deserved reputation for their difficulty, inconclusiveness, and internal inconsistency. Despite these problems, Witt extracts from Aristotle's text a coherent and provocative view about sensible substance by focusing on Aristotle's account of form or essence. After exploring the context in which Aristotle's discussion (...) of sensible substance takes place, Witt turns to his analysis of essence. Arguing against the received interpretation, according to which essences are classificatory, Witt maintains that a substance's essence is what causes it to exist. In addition, Substance and Essence in Aristotle challenges the orthodox view that Aristotelian essences are species-essences, defending instead the controversial position that they are individual essences. Finally, Witt compares Aristotelian essentialism to contemporary essentialist theories, focusing in particular on Kripke's work. She concludes that fundamental differences between Aristotelian and contemporary essentialist theories highlight important features of Aristotle's theory and the philosophical problems and milieu that engendered it.

Apart from his intrinsic importance, as one of the three or four greatest of all philosophers, Aristotle is important on having given for many centuries the greatest influence in moulding the thought of European countries.

It was nearly carried out by the end of the war. Having no hope of survival, I buried my manu script in the earth, without however any expectance of a better lot for it. (shrink)

This book is a study of Aristotle's metaphysics in which the central argument is that Aristotle's views on substance are a direct response to Plato's Theory of Forms. The claim is that Aristotle believes that many of Plato's views are tenable once one has rejected Plato's notion of separation. There have been many recent books on Aristotle's theory of substance. This one is distinct from previous books in several ways: firstly, it offers a (...) completely new, coherent interpretation of Aristotle's claim that substances are separate in which substances turn out to be specimens of natural kinds. Secondly, it covers a broad range of issues, including Aristotle's criticism of Plato, his views on numerical sameness and identity, his epistemology and his account of teleology. There is also a discussion of much of the recent literature on Aristotle. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Notes and Discussions ARISTOTLE'S "DE MOTU ANIMALIUM" AND THE SEPARABILITY OF THE SCIENCES In contrast to Plato's vision of a unified science of reality and with a profound effect on subsequent natural science and philosophy, Aristotle urges in the Posterior Analytics and elsewhere that scientific knowledge is to be pursued in limited, separable domains, each with its own true and necessary first principles for the explanation of a (...) discrete range of phenomena, that is, accepted observations and beliefs, from which its investigations are launched (An. Pr. 46al7ff.; An. Post. 74b25, 76a26-3 o, 84b14-18, 88a31; Cael. 3o6a6ff.; Gen. An. 748a7ff.). In an early introduction to a course of lectures on the natural sciences, Aristotle also indicates the order in which those sciences ought to be presented (Mete. 338a2o-~9, 339a5-9; cf. Cael. 268al6, Part. An. 644b~2ff.). The plan is to start with a general discussion of change and motion, then progress to studies of specific natural phenomena, ending with the many species of plants and animals. In the theory of demonstration in Posterior Analytics 1, which is concerned with the organization, justification, and teaching of a finished science, Aristotle maintains that terms cannot ordinarily cross genera; for example, geometry cannot provide demonstrations of truths of arithmetic or aesthetics. Demonstration of a theorem of some one science by means of another can be accomplished when and only when the sciences are related as "subordinate " to "superior" (75b14-17), for example, as harmonics to arithmetic or optics to geometry. A superior science may supply the "reason" for a "fact" known to obtain in the subordinate science (78b34-79a6). Evidently at least part of what he has in mind is the relation between pure and applied sciences.' Aristotle's practice as well as a number of methodological remarks ' See ThomasAquinas,In Post.

[65] 66 HISTORY OF PHILOSOPHY suggest also that the strictures of the Posterior Analytics are not intended to prohibit the heuristic use of material from other disciplines in research (see e.g., Top. 1.14; Part An. 639b17ff., 641a6-14, 642alo-14, 645b15-2o; Ph. 192b8-34, 199a8-21, 199a33-b5). The requirements for science laid down here are very strict, and it is sometimes maintained that Aristotle violates them himself to some degree in other works, but it is not usually believed that he ever denies the separability of the sciences in general. Martha C. Nussbaum has recently presented a lively challenge to this concensus? She argues that Aristotle's late, little known work De Motu Animalium represents a radical but "deliberate and fruitful" rejection of his earlier philosophy of science as enunciated in the Organon and not seriously questioned in other, subsequent writings. Her claim is that in his mature thought about the sciences Aristotle arrives at a significantly "less departmental and more flexible picture of scientific study" (p. 113) and comes to hold that "no inquiry is genuinely separable from a whole group of interlocking studies, and no being can be extensively studied without an account of its placement in the whole of nature" (p. 164). Nussbaum's conclusion is probably not intended to be as Platonic as it may appear at first blush, for she seems actually to be speaking only of connections between sciences of different substances. There is no suggestion that the study of beauty or health or geometry, say, is on a par with the sciences of substances. Nor does she suggest that Aristotle wavers in his conviction that there are fundamental cleavages between the practical and theoretical sciences, which will make a full-blown science of ethics-politics look very different from the demonstrative science of meteorology, for example. Nevertheless, even if limited to the natural sciences of substances, her claim remains an important and interesting one. She holds, more specifically, that Aristotle departs from his earlier position as follows: (1) He recognizes that the biological study of various modes of local motion... (shrink)

In a well-known passage Aristotle ascribes to Plato, or as some think to his followers, the dictum, γρ ριθμóς στιν κ νòς κα τς ορίστον , ‘Number is from the one and the undetermined dyad ’, but what this apparently simple statement means has remained a mystery until modern times. In other passages Aristotle expands it to explain that the indefinite duality is a duality of the great and small, e.g., ς μν ον λην τò μγα κα τò μικρòν εναι (...) ρχς, ς δ' οσίαν τò ν. ξ κείνων γρ κατ μθεξιν το νòς εναι τος ριθμος . ‘As the matter he posits the great and small for principles, as substance the one; for by the mixture of the one with them he says numbers .’ This identification of the dyad with the great and small, elsewhere called τò νισον and τò πειρον , gives a first clue to its nature. In a notable article in Mind 35 , 419–40, continued in vol. 36, , 12–33, and amplified by D' Arcy Wentworth Thompson in vol. 38 , 43–55, A. E. Taylor first suggested a connexion between the indefinite duality and the modern theory of continued fractions. In the light of subsequent research in the history of Greek mathematics it may now be asserted with a high degree of confidence that his conjecture was almost certainly correct; but it was then no more than a conjecture, and when he looked for confirmation he looked in the wrong direction.

This is an Editorial Note for the special volume of the journal Manuscrito (42: 4) devoted to Aristotle's theory of demonstration and its logical and metaphysical entanglements, which has been organized by me and Breno Zuppolini (as Guest Editors), with papers authored by Benjamin Morison, Owen Goldin, David Bronstein, Michail Peramatzis, Andrea Falcon, Laura Castelli, Paolo Fait, Joseph Karbowski, Adam Crager, Klaus Corcilius, Robert J. Hankinson, Raphael Zillig and Pieter Sjoerd Hasper.

In his commentary on Aristotle’s Physics, Nicole Oresme propounds a very specific theory of the ontological status of accidents. Characteristic of Oresme’s view on accidents is that he does not consider them accidental forms, but only so-called condiciones or modi of the substance. Unlike the term “modus”, the term “condicio” seems to be very characteristic of Oresme’s own terminology. Up to now it has been unknown whether Oresme exerted any influence with his condicio-theory of accidents. This paper (...) presents an anonymous 14th-century commentary on Aristotle’s Meteorology, in two Questions of which the term “condicio” occurs in an ontological context. Moreover, the text shows further striking coincidences with known works by Oresme, and this makes an influence by Oresme appear all the more probable. (shrink)

Aristotle's theory of human action is an impressive achievement that has served philosophy well for more than two thousand years. In every philosophical era it is explored anew--and with great profit. As a contribution to contemporary efforts in this regard, the present dissertation aims to lay out, lucidly and in detail, the various components of Aristotle's action theory. ;Since actions, according to Aristotle, constitute a sub-class of "the voluntary", the dissertation begins by examining Aristotle's account (...) of voluntary activities. It discusses the chief characteristics shared by all such activities, and compares the Nicomachean and Eudemian accounts. ;Perception is examined next, because percepts and their lingering traces , according to Aristotle, are the triggers of desire. And desire provides the impetus for animal behavior and human action. Aristotle's analysis assumes a rich array of desire-types, including appetites, passions, emotions, and wishes, all of which are analyzed in the dissertation. ;The keys to adult human action--distinguishing it from animal and child behavior--are deliberation, "choice" and the so-called "practical syllogism". The dissertation examines these in some detail and produces a model of the practical syllogism. ;Once the practical syllogism has been examined, the dissertation considers the question of whether Aristotle's theory of action provides a successful resolution of the so-called "problem of free will". It is argued that Aristotle--despite common misconceptions to the contrary--was aware of the problem and had a promising philosophical basis for its solution. (shrink)
