In this paper, I articulate three kinds of division that Plato and Aristotle acknowledge to be proper, valid methods of division, namely, diairesis, parallel division, and chiasmus. I attempt to explain the relationship among the three kinds of division, namely, how they transform from one to another. Starting with Plato’s division of constitution in the Statesman, I illuminate that from ostensible diairesis emerges a parallel division, and the parallel division causes a (...) cross-division to occur. Thus, the sixfold division of constitution is not a diairesis but rather is a 3 x 2 cross-division. Inheriting the three kinds of division from Plato, Aristotle advances the form by providing a theoretical explanation to the transformation of the three kinds of division. In Topics Z6, Aristotle prescribes two conditions under which a parallel division can originate from or construct ostensible diairesis and how the parallel division further causes a cross-division to occur.

Here I interpret a central passage in Plato's Sophist by focusing on understudied elements that provide insight into the fit of the dialogue's parts and the Sophist-Statesman diptych as a whole. I argue that the Eleatic Stranger's account of what the dialectician "adequately views" at Sophist 253d1-e3 involves both division and the communion of ontological kinds, not just one or the other as has been typically argued. I also consider other key passages and the turn throughout the dialogue from (...) imagistic opining toward noetic understanding. (shrink)

At 287c of the Statesman the Eleatic Visitor — or, more deeply, Plato — faces a daunting task. Because statesmanship has been shown to collaborate with “countless” other arts that share with it the work of “caring” for the city, to understand statesmanship requires distinguishing these arts into an intelligible set of kinds and recognizing how these might go together. Accordingly, the Visitor abandons the mode of division he has practiced without exception up until this moment, bifurcation or “halving,” (...) and offers, instead, a sorting of the arts into fifteen kinds of work. How was Plato able to get his bearings towards the heterogeneous multiplicity of the arts in order to do this sorting? In this paper I suggest that he may have found a paradigm in the double octave matrix of notes from which, according to contemporary musical theory, the seven musical “modes” are drawn. To show the plausibility of this suggestion, I first reconstruct the double octave matrix, which was later to be called the Greater Perfect System, and then show a striking series of points of substantive and structural analogy that hold between this matrix and the Visitor’s division of the arts into fifteen kinds.

Le Politique est généralement conçu comme un dialogue décousu et manquant d'unité, au mieux comme une succession de méthodes et de voies de recherche différentes (division dichotomique, mythe, paradigme) visant chacune à définir le politique. Le présent article vise au contraire à montrer que l'unité du dialogue est coextensive au développement d'une unique diaíresis, et ce en soulignant, à partir de ce que le texte dit lui-même, que le mythe, la méthode par paradigme et l'analyse des constitutions existantes ne (...) sont que des moyens permettant à la division de tracer le sentier qui mène au politique tel qu'il devrait être. L'ensemble des passages méthodologiques du dialogue permet ainsi d'expliquer comment le Politique explore les possibilités et souligne les limites de la méthode diairétique. Plato's Statesman is usually read as a tedious and carelessly written exercise in dialectic, or, more charitably, as a patchwork of loosely connected applications of different methods of definition of statesmanship (division, myth and paradigm). In this paper, I argue that this much disputed problem of the unity of the dialogue can be solved, provided one reads the whole dialogue as what it claims to be, i.e. the developpment of a single diaíresis. It can be shown that the Eleatic Visitor makes use of the myth, of the analysis of paradigms and of the treatment of non-ideal constitutions as means to following a single path, throughout the whole dialogue, that leads to the definition of statesmanship as it should be. The Statesman emerges as Plato's most profound reflection on the possibilities and the limits of the diairetic method. (shrink)

"Plato's Statesman reconsiders many questions familiar to readers of the Republic: questions in political theory - such as the qualifications for the leadership of a state and the best from of constitution (politeia) - as well as questions of philosophical methodology and epistemology. Instead of the theory of Forms that is the centrepiece of the epistemology of the Republic, the emphasis here is on the dialectical practice of collection and division (diairesis), in whose service the interlocutors also deploy (...) the ancillary methods of myth and of models (paradeigmata). Plato here introduces the doctrine of due measure (to metrion) and a conception of statecraft (politikē) as an architectonic expertise that governs subordinate disciplines such as rhetoric and the military - doctrines later developed by Aristotle. Readers will find a sustained defence of the importance of expertise (technē or epistēmē) in the conduct of affairs of state, a robust (although not unqualified) defence of the rule of law, and an unsparing but nuanced critique of democratic government. The chapters in this volume provide a comprehensive and detailed philosophical engagement with the entirety of Plato's wide-ranging dialogue, with successive chapters devoted to the sections of the dialogue as it unfolds, and an introduction that places the dialogue in the context of Plato's philosophy as a whole. While not a commentary in the traditional sense, the volume engages with Plato's Statesman in its entirety" -- Publisher's description. (shrink)

Despite Aristotle’s claim in Topics I that all dialectical argument is either syllogism or epagōgē, modern scholars have largely neglected to assess the role of epagōgē in Platonic dialectic. Though epagōgē has no technical use in Plato, I argue that the method of collection (which, along with division (diairēsis), is central to many of the dialogues’ accounts of dialectic) functions as the Platonic predecessor to Aristotelian epagōgē. An analysis of passages from the Sophist and Statesman suggests that collection is (...) a purificatory practice. I argue that collection is not only Plato’s account of generalization from a sensible many to an intelligible many, as suggested by the Phaedrus, but also functions as a method of diacritical selection that allows inquiry to move from the intelligible many produced by division to the intelligible unity of a definition. This reading contributes a deeper understanding of the mutual relationship of division and collection within Platonic dialectic as well as a way of unifying the accounts of dialectic in the Sophist and Statesman with the otherwise idiosyncratic account of dialectic in the Republic. Finally, this analysis of Platonic epagōgē sheds light on the connection between inquiry and argument present in Aristotle’s use of epagōgē. (shrink)

This paper explores the role of early imperial Peripatetics – in particular, Andronicus of Rhodes, Boethus of Sidon, Herminus, and Alexander – in the development of the canonical reading of the Categories influentially maintained by Porphyry. I investigate the common threads of Middle Platonist and Peripatetic views on the value of the Categories, focusing on the utility of the method of division (diairesis) for acquiring knowledge (epistêmê), and argue for a shared Peripatetic-Platonist consensus about the reasons why the (...) Categories should ground the philosophical curriculum. In particular, I suggest that Andronicus of Rhodes and Eudorus might have played a significant role in the development of this consensus.

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 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)

The aim of this paper is to investigate Plato’s conception of the whole in the Phaedrus and the theory of medical dialectic underlying this conception. Through this analysis Plato’s conception of kairos will also be adressed. It will be argued that the epistemological holism developed in the dialogue and the patient-typology emerging from it provides us with a way of perceiving individual situations of medical discourse and decision-making that makes it possible to bridge the gap between observations of a professional (...) nature, i.e. of diagnostics and therapy—of whom to treat and in what magnitude—and individual patients’ perceptions of their situation. Besides, it will be argued that such a patient-typology represents a conceptual framework to assess and deal normatively with patients’ ailments and needs that is more robust than the current standards in use, i.e. the Subjective Standard, the Reasonable Person Standard and the Professional Practice Standard. Finally, it will be argued that the possession of kairos, which according to Plato is the hallmark of a true physician, represents a normative conception of time that today’s medicine is in need of revisiting.

Plato’s Timaeus provides a significant, original account of diseases afflicting the body and soul. The causes of disease are explained according to the same physical principles that account for the motion of the four elements in the universe. As a result, medical expertise concerning the microcosm of the human body depends on cosmological expertise concerning the macrocosm of the universe. in addition, the methods of division and collection (diairesis and sunagōgē) that Plato uses in other late dialogues are (...) employed in the Timaeus to classify ailments according to differences in their dunamis. Each of the three main kinds of disease is caused by a unique kind of bodily motion, which explains why the same body parts, humours, and elements are involved in multiple kinds of disease. (shrink)

At Sophist 253d-e the Eleatic Visitor offers a notoriously obscure description of the fields of one-and-many that the dialectician “adequately discerns.” Against the readings of Stenzel, Cornford, Sayre, and Gomez-Lobo, I propose an interpretation of that passage that takes into account the trilogy of Theaetetus-Sophist-Statesman as its context. The key steps are to respond to the irony of Socrates’ refutations at the end of the Theaetetus by reinterpreting the last two senses of logos as directed to forms and to recognize (...) their correlation with the two different modes of diairesis practiced by the Eleatic Visitor. These steps position us to recognize in the Visitor’s remarks at Sophist 253d-e a schematic description of the two kinds of eidetic field that the two modes of diairesis trace. (shrink)

It is not certain when or by whom S0009838800011642_inline1 and S0009838800011642_inline2 were first technically distinguished as genus and species. The distinction does not appear in Plato's extant writings, whereas Aristotle seems to take it for granted in the Topics, which is usually regarded as among his earliest treatises. In his dialogues Plato seems able to use S0009838800011642_inline3 interchangeably to denote any group or division in a diairesis, including the group that is to be divided.
