Aristotle: Dialectic

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

Although the commentary on Aristotle’s problematic discussion of slavery is vast, his discussion of nobility receives little attention. The fragments of his dialogue On Noble Birth constitute his most extensive examination of nobility, and while their similarity to the παμβασιλεύς of the Politics has recently been recognized, their relevance to natural slavery has hitherto gone unnoticed. Yet by declaring that true nobles – particularly the god-like ἀρχηγός – preternaturally possess superhuman characteristics, Aristotle precludes their easy inclusion in the kind “human” (...) in a manner inversely mirroring the preternatural subhumanity of natural slaves. Building on recent scholarship which argues that Aristotle’s “defense” of natural slaves is better understood as an indictment, On Noble Birth becomes most coherent if read as a hypothetical investigation into what would be required for “nobility” to name something true rather than equivocal, with the conclusion that “true nobility” is an empty set.

In Categories 7, Aristotle gives two different accounts of relatives, and presents the principle of cognitive symmetry, which seems to help distinguish between relatives and some secondary substances. I suggest that the long-disputed difference between the two accounts lies in a difference in the determination of the categorial status of the object in question, and I formulate the principle of cognitive symmetry such that it plays a crucial role in making explicit how one conceptualizes the categorial status of the object. (...) I then set out some consequences following from this understanding for certain interpretive issues, such as the unity of the Categories. (shrink)

By scholarly consensus, extant fragments from, and testimony about, Aristotle’s lost dialogue Eudemus provide strong evidence for thinking that Aristotle at some point defended the human soul’s unqualified immortality (either in whole or in part). I reject this consensus and develop an alternative, deflationary, speculative, but textually supported proposal to explain why Aristotle might have written a dialogue featuring arguments for the soul’s unqualified immortality. Instead of defending unqualified immortality as a doctrine, I argue, the Eudemus was most likely offering (...) a dramatically engaging propaedeutic to the sort of philosophical inquiry about the soul and its prospects that Aristotle pursues more scientifically in the De anima and Parva naturalia.

In this article, I tackle a heretofore unnoticed difficulty with the application of Pyrrhonian scepticism to science. Sceptics can suspend belief regarding a dogmatic proposition only by setting up opposing arguments for and against that proposition. Since Sextus provides arguments exclusively against particular geometrical definitions in Adversus Mathematicos III, commentators have argued that Sextus’ method is not scepticism, but negative dogmatism. However, commentators have overlooked the fact that arguments in favour of particular geometrical definitions were absent in ancient geometry, and (...) hence unavailable to Sextus. While this might explain why they are also absent from Sextus’ text, I survey and evaluate various strategies to supply arguments in support of particular geometrical definitions. (shrink)

This is an excellent translation of Aristotle's De Anima or On the Soul, part of C.D.C. Reeve's impressive ongoing project of translating Aristotle's works for the New Hackett Aristotle. Reeve's translation is careful and accurate, committed to faithfully rendering Aristotle into English while making him as readable as possible. This edition features excellent notes that will greatly assist readers (especially in their inclusion of related passages that illuminate the sections they annotate) and an introduction that situates the work within Aristotle's (...) scientific method and his overall view of reality.

I discuss the methodological passage in the begin- ning of Ethica Eudemia I.6 (1216b26-35), which has received attention in connection with Aristotle’s notion of dialectic and his methodology in Ethics. My central focus is not to discuss whether Aristotle is prescribing and using what has been called the method of endoxa. I will focus on how this passage coheres with the remaining parts of the same chapter, which also are advancing methodological remarks. My claim is that the meth- od of (...) Ethica Eudemia I.6 is in agreement with many features of Aristotle’s theory of explanation as presented in the Posterior Analytics: Aristotle’s main concern is a warning against misuses of explanatory arguments. (shrink)

In this paper, I analyse EE I 6, where Aristotle presented a famous methodological digression. Many interpreters have taken this chapter as advocating a dialectical procedure of enquiry. My claim is that Aristotle does not keep a dialectical attitude towards endoxa or phainomena in this chapter. In order to accomplish my goal, I shall show that EE I 6 does not provide enough evidence for the dialectical construal of it, and that this construal, in turn, hangs on some assumptions brought (...) out from other Aristotelian works (EN and Top.), which do not provide good evidence as well. By the analysis of these assumptions, I intend to show that Aristotle is not carrying out any sort of dialectic, especially dialectic conceived as conceptual analysis seeking the salvage of phainomena or endoxa.

A presente pesquisa visa caracterizar o método empregado por Aristóteles na Ethica Nicomachea a partir de uma análise que contrasta duas interpretações: de um lado, a tese já tradicional que busca ver na filosofia prática do Estagirita um método estritamente dialético; de outro, a tese alternativa, explorada apenas recentemente, que aponta o uso, na EN, de um procedimento filosófico próximo das prescrições sugeridas nos Segundos Analíticos para a busca definicional nas ciências. O núcleo da primeira tese deverá ser analisado sob (...) duas perspectivas: (i) examinando um conjunto de textos que revelam o teor dialético da filosofia aristotélica; e (ii) avaliando o processo de expansão da noção de dialética e suas implicações para os estudos aristotélicos. Alternativamente, (i) será examinado como um modelo de tipo definicional pode reaproximar a ética do registro científico dos Segundos Analíticos sem necessariamente se valer de argumentos dialéticos. Por fim (ii), proponho uma versão deflacionária do que deve contar como método dialético em Aristóteles. (shrink)

This paper challenges a widespread reading of Aristotle’s use of dialectic in the treatment of aporiai. According to this reading, the search for a resolution of an aporia is supposed to proceed by arguing against conflicting theses to refute one of them. I argue that this reading is not satisfactory and propose an alternative, based on an often overlooked distinction between two dialectical procedures, the refutation (elenchos) of a thesis and the resolution (lysis) of an argument. These two terms are (...) employed fairly consistently by Aristotle in the treatises as well. Since an aporia requires not merely conflicting theses, but conflicting arguments for those theses, I contend that the ideal way out of aporiai involves a critical analysis of those arguments, akin to that involved in the dialectical resolution. A relevant implication of this reading is that it expands the critical use of dialectic for philosophy, and points to the specific philosophical utility of the Sophistical Refutations. (shrink)

The main aim of the French logician and philosopher Petrus Ramus was to provide a method of teaching the liberal arts enabling the completion of the undergraduate program of studies in 7 years. This method was based on a new logic, in which the complex structure of Aristotle’s Organon and of the Summulae logicales of Peter of Spain is reduced to two main doctrines: the invention of arguments, by which it is possible to find the notions for reasoning and disputing (...) in any discipline, and the disposition of arguments in judgment, i.e., in propositions and syllogisms. Since this logic applies both to demonstrative and to probable reasoning, Ramus and Rudolph Agricola, who first introduced it, labeled it as dialectic. Ramus completed this twofold dialectic with a method, according to which disciplines have to be taught by providing general definitions, to be explained by subsequent dichotomous divisions. According to Ramus, this method ensures a well-ordered hierarchy and division of disciplines, and an efficient means to teach them in a shorter time than in the pedagogical programs of Juan Luis Vivès, Johann Sturm, and Philipp Melanchthon. This method had its main diffusion in the pre-university institutions such as the German gymnasia and gymnasia illustria (e.g., of Herborn), while in Reformed and Catholic universities the acceptance of Ramism was hindered by the predominance of the Aristotelian curriculum.

In Topics I.2, Aristotle famously claims that dialectic, as a critical inquiry, affords the path to the primary principles of science. This article sets out from the assumption that Aristotle shares with Plato the suspicion that dialectical critique cannot contribute to the advancement of scientific knowledge as long as it is of the Socratic, elenctic kind, since its only benefit is to refute false beliefs. But when Plato in the Theaetetus has Socrates act as a midwife to his fellow men, (...) he offers an alternative picture of dialectical critique that also, it is argued, captures the spirit of Aristotle’s dialectical work, especially as pursued in the Metaphysics. In Aristotle, however, the mission of Socratic midwifery, to help other individuals give birth to knowledge that was already innate to them, is transformed into a project that centers on the liberation of the as yet dormant and inarticulate truth of the tradition.

In Nicomachean Ethics (= Eth. Nic.) 10.2, Aristotle addresses Eudoxus’ argument that pleasure is the chief good in his characteristically dialectical manner. The argument is that pleasure is the chief good, since all creatures, rational (ἔλλογα) and non-rational (ἄλογα) alike, are perceived to aim at pleasure (1172b9–11).1 At 1172b35–1173a5, Aristotle turns to an objection against Eudoxus’ argument. For some object (οἱ δ᾽ἐνιστάμενοι) to the argument by questioning one of its premisses, namely that what all creatures aim at is the good (...) (1172b12–15). Instead, they claim that what all creatures aim at is not good (ὡς οὐκ γαθὸν οὗ πάντ᾽ ἐφίεται, 1172b36). This claim is reasonably taken to mean that not everything that all creatures aim at is good. But, as we shall shortly see, Aristotle dismisses it in a way suggesting a less charitable interpretation. At any rate, the significance of this objection is that it challenges the strong claim that what all creatures aim at is the good with an argument against the weaker claim that what all creatures aim at is good (or a good). For if the weaker claim is refuted, then the strong claim is refuted as well. Aristotle takes issue with the argument against the weaker claim, but without committing himself to the strong claim.

I claim that, in the Topics, Aristotle advises dialectical questioners to intentionally argue fallaciously in order to escape from some dialectically awkward positions, and I work through the consequences of that claim. It will turn out that, although there are important exceptions, the techniques for finding arguments described in Topics I–VII are, by and large, locations that Aristotle thought of as appropriate for use in philosophical inquiry. The text that grounds this claim, however, raises a further problem: it highlights the (...) solitary nature of philosophical inquiry, which puts into question the philosophical relevance of Topics VIII. I find that the Topics provides inadequate grounds for thinking that Aristotle saw Topics VIII as describing standards or techniques of argument that were appropriate for philosophy, and so these texts cannot be used by contemporary commentators to shed light on Aristotle's philosophical practice. Finally, although Aristotle saw philosophy as a solitary activity, he th.. (shrink)

The purpose of this paper is to give an account and a rational reconstruction of the heuristic advice provided by Aristotle in the Topics and Prior Analytics in regard to the difficulty or ease of strategic planning in the context of a dialectical dialogue. The general idea is that a Questioner can foresee what his refutational syllogism would have to look like given the character of the thesis defended by the Answerer, and therefore plan accordingly. A rational reconstruction of this (...) advice will be attempted from three perspectives: strategic planning based on the acceptability of Answerer’s thesis, strategic planning based on the predicational form of the thesis, strategic planning based on the logical form of the thesis. In addition, we will provide an illustration of the potential of this heuristic advice as we apply it to the interpretation of a fragment from Plato, presuming that, in a similar way, a reading of this kind might be more generally applicable in the interpretation of the Platonic dialogues.

Despite the enthusiasm generated by social constructionism in the study of scientific debates, this contribution shows that – down to their praxeological dimension – the study of scientific controversies can benefit from sources ignored in today sociological literature. The contribution discloses these sources from the works of Shams al-Dīn al-Samarqandī (ca. 1250–ca. 1302), who is the first author to have offered etiquettes of investigation and debate (ādāb al-baḥth wa-al-munāẓara). Consequences are drawn towards constructivist epistemology.

The period from Plato's birth to Aristotle's death (427-322 BC) is one of the most influential and formative in the history of Western philosophy. The developments of logic, metaphysics, epistemology, ethics and science in this period have been investigated, controversies have arisen and many new theories have been produced. But this is the first book to give detailed scholarly attention to the development of dialectic during this decisive period. It includes chapters on topics such as: dialectic as interpersonal debate between (...) a questioner and a respondent; dialectic and the dialogue form; dialectical methodology; the dialectical context of certain forms of arguments; the role of the respondent in guaranteeing good argument; dialectic and presentation of knowledge; the interrelations between written dialogues and spoken dialectic; and definition, induction and refutation from Plato to Aristotle. The book contributes to the history of philosophy and also to the contemporary debate about what philosophy is. (shrink)

Few arguments from the past have stirred up as much interest as Aristotle’s “Third man” and not so many texts have received as much attention as its account in chapter 22 of the Sophistici elenchi. And yet, several issues about both remain highly controversial, starting from the very nature of the argument at stake and the exact signification of some of its features. The essay provides a close commentary of the text, dealing with its main difficulties and suggesting an overall (...) interpretation of Aristotle’s discussion of the “Third Man” argument. (shrink)

Like the doctrine of the categories in general, Aristotle’s category of the relative fulfils disparate functions: On the one hand, the category of the pros ti fulfils a dialectic or logical function that aims at the avoidance of fallacies. On the other hand, the category respects the peculiar mode of being of the relative. Taking these two different functions into consideration helps with the interpretation of Aristotle’s two definitions of the relative and his treatment of the properties of the relative (...) in Cat. 7, with the question whether corresponding relatives are of equal priority or ontologically independent, with the genus-species problem , and with the categorical classification of potency and act.

Dieser Band umfaßt alle Aufsätze des Wiener Philosophen Franz Ungler. Zur antiken Dialektik: Die Bestimmung der Freiheit durch Aristoteles enthält, daß er einerseits die Unvergleichlichkeit menschlicher Freiheit mit entelechialer Notwendigkeit sieht, andererseits das telos menschlicher Praxis in der eudaimonia analog dem natürlich Seienden ansetzen möchte. So ist Aristoteles in die Dialektik des Freiheitsbegriffes eingestiegen; allein diese ist von ihm nicht so betrachtet worden, daß sie systematische Gestalt annehmen konnte. Zur neuzeitlichen Dialektik: Neuzeitliche Transcendentalphilosophie hat den im Begriff der Freiheit implizierten (...) Anfang des philosophischen Systems als solchen gesetzt. Das bedingt ihrer selbst bewußte Dialektik, die sieht, daß das Prinzip des zu vermeidenden Widerspruchs den daseienden Widerspruch voraussetzt. Versuche, Freiheit als sogenannten widerspruchsfreien Begriff zu fassen, sind Bestrebungen, vor der Konkretheit ihres Begriffes in abstrakte, ideologische Vorstellungen zu flüchten. (shrink)

One of the most common strategies in philosophical dispute is that of accusing the opponent of begging the question, that is, of assuming or presupposing what is to be proved. Thus, it happens quite often that the credibility of a philosophical argument is infected by the suspicion of begging the question. In many cases it is an open question whether the suspicion is grounded, and the answer lurks somewhere in the dark of what the proponent of the argument does not (...) say. This is why it may take years, or even centuries, before the begging of the question is brought to light. But few philosophers would deny that once it is established that a certain argument begs the question, that argument has to be rejected without hesitation: question-begging arguments are bad arguments, hence one should not appeal to them. Logicians traditionally classify begging the question as a fallacy, that is, as a bad reasoning that seems good at first sight. The fallacy is known under the name of petitio principii. This paper originated in our dissatisfaction with definitions of petitio principii found here and there in logic textbooks. Although it is uncontroversial that there is something wrong with begging the question, it is not clear from those definitions what is wrong. (shrink)

Aristotle is often called the father of the history of philosophy. However, if his references to earlier theses are to be taken as historical reports in our sense, then they must also be subject to historical critique – which is much to their disadvantage. However, looking through the function of his doxographies and furthter references to earlier theses shows that such a historical view is an anachronism in a way similar to the expectation of finding science in Aristotle. Rather the (...) references are made in a topical attitude. In this way the outlindes of the dominant opinions become explicit and only thereby argumentatively accessible. At the same time the unavoidable integration into tradition is consciously realised. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Aristotle’s “De Interpretatione”: Contradiction and Dialectic by C. W. A. WhitakerEugene GarverC. W. A. Whitaker, Aristotle’s “De Interpretatione”: Contradiction and Dialectic. Oxford: Clarendon Press, 1996. Pp. x + 235. Cloth, $60.00.Traditionally, the De Interpretatione is placed in the Organon between the Categories and the Prior Analytics. Where the Categories is about single terms and the Analytics about inferences, the De Interpretatione is about propositions. That traditional view is (...) presupposed by most contemporary studies of the work, which “concentrate on a small number of passages, which have been treated as isolated oases of philosophical interest in an otherwise barren work,” highlights which include “Aristotle’s semantic theory of philosophy of language” in the first chapter, the first four “linguistic chapters,” and chapter 9 on the Sea Battle (1). I suppose that the square of opposition could be added to Whitaker’s list.Whitaker, in this republication of a doctoral dissertation, wants to challenge both the traditional view and the contemporary concentration by instead studying the work as a coherent whole, whose subject, it turns out, is not propositions after all but “contradictory pairs, which are central to the working of dialectic” (2). The book then proceeds through the De Interpretatione, chapter by chapter. If he succeeds, the De Interpretatione will henceforth be read as preparation for the Topics, rather than for the Analytics. There are also three appendices examining the use of such contradictory pairs in Metaphysics IV, the Topics, and the Posterior Analytics.Thus, the first five chapters of the De Interpretatione explain the nature of assertions, name and verb, and “before that, how language is related to thought and to the real world, and how it is that utterances can make claims about things which are true or false” (8). Where names, verbs, and propositions are part of our ordinary understanding of language, contradictory pairs are not, but are a philosophical understanding of a linguistic structure that has a specifically philosophical, dialectical, purpose. The rest of the De Interpretatione, from chapter 6 on, is the examination of contradiction. Chapters 7–9 classify contradictory pairs by different criteria. Each of these chapters isolates an exception to “the rule that, in every contradictory pair, one member is true and the other false” (79). Chapter 7 looks at the first exception to the rule, “non-universal statements about universals” (91). Whitaker’s project looks good here, since he then shows the dialectical uses of such propositions, and denies their value for the deductive logic of the Analytics. Similarly, in Chapter 8 Aristotle looks at “apparently simple assertions... which are not single” (105), which also have important uses in dialectic. Finally, chapter 9 looks at the third exception to the rule, future singular assertions. One payoff of this book is to place the sea battle discussion in its Aristotelian context. [End Page 459] Whitaker says that most discussions of the sea battle assume that what is at stake is what he calls the “Principle of Bivalence” in which every assertion is either true or false. He instead insists that it is contradictory pairs, not single assertions, that are being tested by future contingents. He thus concludes: “Dialectic is a universal discipline, and its questioning can cover any subject where a question can be posed which has a right and a wrong answer. Chapters 7 to 9... demonstrate that there are limits to the universality of dialectic” (128).Whitaker follows the De Interpretatione chapter by chapter in the remainder of the book. He shows how the later chapters assist the dialectician in “sorting assertions into contradictory pairs” (181). And just as De Interpretatione begins with a consideration of the relation of language, thought, and the world, so it ends by showing the connection between contradictory propositions and opposed beliefs.Whitaker rarely strays from the De Interpretatione to show how our understanding of dialectic is improved by attention to this prerequisite. When he does, for example in a very short discussion of the relation of problems and propositions in the Topics, the results are illuminating. I would have liked more. This book should be useful to the growing numbers of scholars interested in Aristotle’s art of dialectic... (shrink)

Há embutida nas obras de Aristóteles uma ideia medular, que escapou à percepção de quase todos os seus leitores e comentaristas, da Antiguidade até hoje. Mesmo aqueles que a perceberam e foram apenas dois, que eu saiba, ao longo dos milênios limitaram-se a anotá-la de passagem, sem lhe atribuir explicitamente uma importância decisiva para a compreensão da filosofia de Aristóteles. No entanto, ela é a chave mesma dessa compreensão, se por compreensão se entende o ato de captar a unidade do (...) pensamento de um homem desde suas próprias intenções e valores, em vez de julgá-lo de fora; ato que implica respeitar cuidadosamente o inexpresso e o subentendido, em vez de sufocá-lo na idolatria do texto coisificado, túmulo do pensamento. A essa ideia denomino Teoria dos Quatro Discursos. Pode ser resumida em uma frase: o discurso humano é uma potência única, que se atualiza de quatro maneiras diversas: a poética, a retórica, a dialética e a analítica (lógica). (shrink)

The aim of this study is to understand the place of Aristotle’s dialectic in his overall theory of intellectual activity. On the way to this goal, the reader is treated to a novel and exciting interpretation of the nature of dialectic. Evans argues that Aristotelian dialectic is a method for progressing from what is intelligible to some group of discussants to what is intelligible without qualification. Evans goes behind this distinction to discover how dialectic can be, as Aristotle claims, the (...) road to the first principles of all the sciences. (shrink)
