Aristotle's Works in Logic

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)

Celebrated as the equal to the great philosophers of old, namely Plato and Aristotle, whom – as Cassiodorus put it – he taught to speak Latin better than they spoke Greek, Boethius aspired to fully emancipate Roman culture from its Greek models through translations and exegesis so faithful they would leave nothing more to be desired from the original. The essay focuses on Boethius philhellenism, without complexes insofar as it had little to do either with the mixed feelings of his (...) Roman predecessors or with the plundering agenda of his Christian contemporaries. Special attention is paid to the close relationship Boethius established between word for word translations and multi-layered commentaries which he thought of and – albeit partially – carried out as part of the same scholarly endeavour. Devoid of literary pretentions as well as free from aspirations to autonomy, Boethius literal rendering and scrupulous interpretation were meant to be completely self-sufficient. Together they stand out as both the most innovative and the most conservative features of his ambitious cultural project. -/- Célébré comme l’égal des grands philosophes du passé, auxquels il aurait appris à parler Latin mieux qu’ils ne parlaient Grec, Boèce a caressé le rêve d’une émancipation radicale de la culture romaine vis-à-vis des modèles grecs qu’il se proposait de traduire et interpréter assez fidèlement pour que la comparaison avec les sources ne soit plus nécessaire. De son effort de livrer un Aristote et un Platon latins à la hauteur des originaux grecs, nous étudions l’étroite solidarité qui relie la traduction mot-à-mot des textes grecs et la restitution scrupuleuse de leur sens. Cette double tâche, que Boèce a conçue et menée d’un seul tenant, nous est dès lors apparue comme le reflet d’un philhellénisme sans complexes, tout aussi éloigné des sentiments ambivalents que nourrissaient vis-à-vis des hellènes ses devanciers romains que des efforts visant à domestiquer l’héritage classique auxquels se livraient certains de ses contemporains de même confession que lui. Affranchis de tout rêve d’autonomie, les traductions et les commentaires de Boèce se conçoivent comme parfaitement autosuffisants. Ensemble ils constituent ce qu’il y a à la fois de franchement novateur et de profondément conservateur dans son projet de faire parler Latin les sources grecques. (shrink)

Edward Meredith Cope was an English scholar of classics who served as Fellow and Tutor at Trinity College, Cambridge. One of the leading Greek specialists of his time, Cope published An Introduction to Aristotle's Rhetoric in 1867. Though now considered a 'standard work', that Introduction was intended as merely the first part of a full critical edition of the Rhetoric, which was left incomplete on Cope's death in 1873. Cope's manuscripts were collected and edited by John Edwin Sandys, and published (...) in this three-volume set in 1877. Cope's analysis represented an important advance in the modern interpretation of this foundational text on the art of persuasion. Volume 1 contains the Greek text of Book 1 together with a commentary on Aristotle's introduction to his topic and his definition of rhetoric and its subdivisions. (shrink)

In this major contribution to philosophy and rhetoric, Eugene Garver shows how Aristotle integrates logic and virtue in his great treatise, the _Rhetoric._ He raises and answers a central question: can there be a civic art of rhetoric, an art that forms the character of citizens? By demonstrating the importance of the _Rhetoric_ for understanding current philosophical problems of practical reason, virtue, and character, Garver has written the first work to treat the _Rhetoric_ as philosophy and to connect its themes (...) with parallel problems in Aristotle's _Ethics_ and _Politics._ Garver's study will help put rhetoric at the center of investigations of practice and practical reason.

Jamie Dow presents an original treatment of Aristotle's views on rhetoric and the passions, and the first major study of Aristotle's Rhetoric in recent years. He attributes to Aristotle a normative view of rhetoric and its role in the state, and ascribes to him a particular view of the kinds of cognitions involved in the passions.

In this collection edited by Alan G. Gross and Arthur E. Walzer, scholars in communication, rhetoric and composition, and philosophy seek to “reread” Aristotle’s Rhetoric from a purely rhetorical perspective.

This volume contains a critical edition of Bar Hebraeus’ _Book of Rhetoric_ in his _Cream of Wisdom_. The accompanying introduction, translation and commentary explore its relations with the Syriac Aristotle and the Arabic commentary of Ibn Sina.

From its title, which since antiquity has occasioned interpretations of varying ingenuity and implausibility and which the book under review is probably right to judge both inauthentic and inappropriate, to its final chapter, thought to be post-Aristotelian or an exercise by Porphyry and the Greek commentators who followed him, On Interpretation has long been considered one of Aristotle’s most puzzling works. Brief as it is, this treatise was divided into four main parts by Ammonius, dealing with the principles of the (...) assertoric sentence, the proposition consisting of subject and predicate terms only, the proposition which contains an “added predicate”, and modal propositions. Modern commentators tend to find in the work important, but isolated, discussions of general semantic theory, the elements of grammar, and modality and fatalism, but not much else of interest.

The Prior Analytics marks the beginning of formal logic, and is one of the most influential works in the history of thought. It is here that Aristotle sets out his system of syllogistic reasoning. The first book, to which this volume is devoted, offers a coherent presentation of Aristotle's logic as a general theory of deductive argument.

This volume contains a clear and accurate translation of Books I and VIII of Aristotle's Topics, together with a philosophical commentary on these books and additional extracts from Books II and III, and from a related work by Aristotle. This selection gives a good general view of the main ideas of the Topics, a classic treatise on logic and argument. The volume is well suited to the requirements of students, including those who do not know Greek.

This work provides some interesting new results on the notion of the topos and the theory of hypothetical syllogisms in Aristotle based on an incisive interpretation of Aristotle's Topics and certain passages of the Analytics .

The Posterior Analytics contains some of Aristotle's most influential thoughts in logic, epistemology, metaphysics, and the philosophy of science. The first book expounds and develops the notions of a demonstrative argument and of a formal, axiomatized science; the second discusses a cluster of problems raised by the axioms or principles of such a science, and investigates in particular the theory of definition. For the second edition of this volume, the translation has been completely rewritten; and the commentary, which is done (...) with the needs of philosophical readers in mind, has been thoroughly revised in the light of the scholarship of the last twenty years. There is an additional glossary and the bibliography has been extended. (shrink)

WE must first state the subject of our inquiry and the faculty to which it belongs: its subject is demonstration and the faculty that carries it out demonstrative science.

In the Categories, Aristotle addresses two different cases of dual categorization, cases in which the same thing might appear in two different categories: relatives and secondary substances in the first case, qualities and relatives in the second. His treatment of these two cases is markedly different. Ackrill thinks dual categorization poses a dilemma for Aristotle’s project as a whole, but I argue that there is a dilemma only on particular understandings of Aristotle’s purpose in compiling the list of categories. I (...) investigate various interpretations of the categories to find one that explains Aristotle’s reactions to dual categorization, and suggest an interpretation of the peculiar four-fold system of classification in Chapter 2.

The subject of this paper is the issue of human speech in Aristotle, especially in his work Categories. Its primary goal is to elaborate an interpretation of Aristotle’s statements about human speech as a quantity (Cat. 4b20–b39, 5a15–b2) that would allow them to fit reasonably into the whole of Aristotle’s theory of language. The structure of the paper is as follows. In the first part a certain approach to the question of the reconstruction of Aristotle’s theory of language is proposed. (...) The second part, by means of the introduction of the criteria of separability and ontological priority of the first substance, creates a framework for the subsequent analysis of the two basic classifications, which constitute the main theme of Categories. The third part supplies its own interpretation of the ontological status of human speech in the context of the classification schemes in Categories, and this, in the fourth part, is inserted into the greater whole of Aristotle’s theory of language.

The Middle Included is a systematic exploration of the meanings of logos throughout Aristotle’s work. It claims that the basic meaning is “gathering,” a relation that holds its terms together without isolating them or collapsing one to the other. This meaning also applies to logos in the sense of human language. Aristotle describes how some animals are capable of understanding non-firsthand experience without being able to relay it, while others relay it without understanding. Aygün argues that what distinguishes human language, (...) for Aristotle, is its ability to both understand and relay firsthand and non-firsthand experiences. This ability is key to understanding the human condition: science, history, news media, propaganda, gossip, utopian fiction, and sophistry, as well as philosophy. Ömer Aygün finds Aristotle’s name for this peculiar but crucial human ability of “gathering” both experiences is logos, and this leads to a claim about the specificity of human rationality and language.

The purpose of the paper is to discuss Aristotle’s account of homonymy. The major thesis advocated here is that Aristotle considers both entities and words to be homonymous, depending on the object of his criticism. Thus, when he takes issue with Plato, he tends to view homonymy more ontologically, upon which it is entities that become homonymous. When, on the other hand, he gainsays the exegetes or the sophists, he is inclined to perceive homonymy more semantically, upon which it is (...) words that become homonymous. Subsequently, this article shows that Aristotle values homonymy negatively in dialectical discussions, but positively in rhetorical and poetic arts. Finally, the present paper demonstrates that Aristotle regards systematic homonymy as a very useful theoretical tool that makes it possible to critically examine the basic terminological assumptions of any philosophical inquiry.

In this paper I shall defend the traditional claim that Aristotle's nonsubstantial particulars discussed in the second chapter of the Categories are unsharable particulars against G. E. L. Owen's claim that they are sharable universals. I shall proceed by presenting first a sketch of the traditional position that makes explicit why it holds that non-substantial particulars are unsharable particulars. Secondly, I shall sketch Owen's position and recount how it differs in certain important respects from the traditional position. Thirdly, I shall (...) present some of my own considerations that I believe support the traditional position at the expense of Owen's position. Finally, I shall offer what I take to be the primary reason Aristotle was committed to the existence of such odd items as non-substantial particulars. (shrink)

THE notion of quantity is basic and it is no surprise that Aristotle refers to it in many places. There are two main discussions, that in the Categories—a part of the Organon which is of great interest to modern logicians and that spread over the physical treatises. Naturally the two treatments overlap, but modern logic is at a far remove from classical cosmology and it is fairly easy to separate them at their sources. This I have attempted to do by (...) considering quantity as an attribute and as divisible. There follows a brief consideration of the notions arrived at for their relevance to modern mathematics with particular reference to the real number system and the notion of infinity. (shrink)

Did Aristotle, with his categories, classify only expressions or also something extralinguistic? In the second case his classification seems to be not exclusive, at least if the usual universes of discourse are considered. However, if we use certain enlarged universes, which may have more than one individual for each individual of the usual universes, we may construct exclusive general classifications that approach the aristotelian categories. The latter ones should then be considered second order classes that classify classes of individuals. If (...) the individuals are taken from one of the indicated enlarged universes, we can obtain the exclusivity that we do not have for the usual universes. (shrink)

In the Posterior Analytics, Aristotle imposes some requirements on the formulation of scientific propositions: their terms must be able to perform the role of subject as well as of predicate; their terms should be universal; every demonstration must involve “primary” subjects denoted by terms that “cannot be said of another underlying subject”. Several interpreters, inspired by theses from the Categories, believed that this third requirement refers to names and descriptions of particular substances as basic subjects of predicative statements, since they (...) cannot perform the logical role of predicate. However, such reading puts the third requirement in conflict with the other two. I shall argue that this interpretation is wrong and that the third requirement does not assign to singular terms the function of basic subjects of scientific discourse, but rather acknowledges that substantial predicates have a certain prerogative to occur in denoting phrases. Consequently, Aristotle’s three demands turn out to be compatible with one another. (shrink)
