In the first half of the 15ᵗʰ century there was a coherent philosophical system of teaching at the Jagiellonian university, so-called ars vetus, concerning the interpretation of three treatises: Aristotle’s Categories and Hermeneutics and Porphyry’s Isagoge. The question-commentaries on the Categories that have been preserved in several manuscripts show astonishing similarity in solving individual problems – there are three copies of Benedict Hesse’s commentary and one copy of Paul of Pyskowice’s work, moreover, in BJ 1941 there is an (...) anonymous commentary on the Categories that is also very close to the ones mentioned before, to prove that fact. This paper, discussing the four-fold division of opposition in those Polish commentaries on Aristotle’s Categories, is part of the studies on the manuscript material that has not been critically edited yet. The main goal is to show the philosophical views on contraries, contradictories, relatives and possession and privation in a wider perspective, comparing the Polish commentaries’ doctrine with the authoritative text itself.

Translation with notes of Ammonius' Commentary on Aristotle's Categories.

This article focuses on the reception of Aristotle’s Categories by the first three representatives of Greek Neoplatonism: Plotinus (204/205–270 CE), Porphyry (ca. 234–ca. 305 CE), Iamblichus (ca. 242–ca. 325 CE). The first section argues that Plotinus’ acquaintance with Aristotle’s treatises marked a fresh start vis-à-vis the previous Platonist tradition. Aristotle’s views, arguments and vocabulary are ubiquitous in Plotinus writings (the Enneads) and they must be considered an essential part of his philosophical project. Plotinus, however, does not share some of (...) Aristotle’s key theories and is critical of them. The second section focuses on Plotinus’ discussion of Aristotle’s Categories in the tripartite treatise On the Genera of Being (6.1–3). There he rejects the Peripatetic division into ten categories as providing an incomplete account of the genera of being that unduly omits “those which are most authentically beings”, i.e. Plato’s separate Forms. While drawing on earlier Platonist objections to Aristotle, Plotinus’ approach is original insofar as he criticizes Aristotle and his followers not only for omitting intelligible beings in the division of categories, but also for being unable, for this very reason, to work out an adequate division of sensible beings themselves. The third section is devoted to Porphyry, a student of Plotinus’ and the editor of his works. Porphyry worked intensively on Aristotle’s Categories, which he regarded as an introduction not only to logic, but to philosophy as a whole. Unlike Plotinus, Porphyry aimed to integrate Aristotle into Platonism and his engagement with the Categories was a key part of his project after Plotinus’ in-depth criticism. Porphyry’s approach is connected to his view of the subject-matter of the Categories, which he sees as focusing on words insofar as they signify beings, and not on beings as such. The fourth section focuses on some parallels between Plotinus’ Genera of Beings and Porphyry’s works, which may reflect the debate within Plotinus’ school. The fifth section focuses on Iamblichus of Chalcis. Both in theology and in the interpretation of Aristotle’s Categories, Iamblichus aimed to both continue and supplant Porphyry’s work. While Plotinus criticizes Aristotle’s categories for omitting intelligible beings, and while Porphyry accepts Aristotle’s categories insofar as they focus on words signifying sensible things, Iamblichus incorporates his Neoplatonist and Pythagorizing metaphysics into the interpretation of the Categories.

Aristotle‘s categories are presented as a system relying on logic and syntax instead of on meanings. His square of oppositions is found to be of crucial importance.

This volume studies the origin and evolution of philosophical interest in Aristotle's Categories, and illuminates the earliest arguments for Aristotle's approach to logic as the foundation of higher education.

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

Aristotle's categorial scheme had an unparalleled effect not only on his own philosophical system, but also on the systems of many of the greatest philosophers in the Western tradition. The set of doctrines in the Categories, known as categorialism, play, for instance, a central role in Aristotle's discussion of change in the Physics, in the science of being qua being in the Metaphysics, and in the rejection of Platonic ethics in the Nicomachean Ethics. Plainly, the enterprise of (...) categorialism inaugurated by Aristotle runs deep in the philosophical psyche. Even so, despite its wide-reaching influence—and, indeed owing to that influence—any attempt to describe categorialism faces a significant difficulty: experts disagree on many of its most important and fundamental aspects. This article argues that Aristotle's categorial scheme, as is the case with many works in the history of philosophy, is best illuminated by opposing beams of interpretive light. It examines how Aristotle arrived at his list of categories and considers the connection between Aristotle's categories and his hylomorphism. (shrink)

Being an "untimely review", this paper reviews Aristotle's 'Categories' as if they were published today, in the era of computerised information, where categorisation becomes more and more essential for information retrieval. I suggest a systematic ordering of Aristotle's list of categories and argue that Aristotle's discussion of ontological dependency and his focus on concrete entities are still a source of new insight and can indeed be read as a contribution to the emerging field of applied (...) ontology and ontological engineering.

Aristotle’s Categories and Concerning Interpretation, translated and with commentary.

A key figure in the history of Aristotelianism, Porphyry (AD 232/3 - c. 305) was born in Tyre and was a student of Longinus' in Athens and of Plotinus' in Rome. In his commentary on the Categories, Porphyry provided an authoritative interpretation of a notoriously controversial work. Commentators on Aristotle had disagreed fundamentally over whether the Categories was a work of logic, concerning simple terms or the simple concepts they represent, or a metaphysical work addressing the classification by (...) genera of simple entities or concepts. Approaching the Categories as the first of Aristotle's works in logic, Porphyry adopted an earlier Peripatetic view of the Categories as being concerned principally with terms or linguistic items, which he calls "predicates." He successfully defended the Categories against Plotinus, arguing that while it seemed to attack orthodox Platonism by denying the separation of forms and the ontological priority of the universal, it was in fact entirely compatible with Platonism. Because of Porphyry's intervention, the Categories came to serve as a basic textbook of logic for subsequent Neoplatonist teaching. His commentary influenced the Arabic tradition, and Boethius drew heavily on it as well. The full text of Porphyry's commentary was lost, but the extant version is available here in Steven K. Strange's new translation. Ancient philosophers, historians of philosophy, classicists, and medievalists will welcome its appearance in English. (shrink)

"Simplicius' commentary is the most comprehensive account of the debate on the validity of Aristotle's Categories. Simplicius discusses where the differentia of a species (for instance, the rationality of humans) fits into the scheme of categories. Another is why Aristotle elevates the category of Quantity to second place, above the category of Quality. Further, de Haas shows how Simplicius arrives at multiple definitions of "universal" to solve some of the problems."--BOOK JACKET.

"Simplicius starts with a survey of previous commentators and an introductory set of questions about Aristotle's philosophy and about the Categories in particular. The commentator, he says, needs to present Plato and Aristotle as in harmony in most things."-- Publisher description.

INTRODUCTION. Porphyry the Philosopher The most distinguished disciple of Plotinus, his editor and close friend, was without doubt Porphyry. ...

Let us put before us the full list of the ten categories as given in Categories, ch. 4 and Topics, Book I, ch. 9, with their familiar English names.

This paper addresses the problem of the origin and principle of Aristotle’s distinctions among the categories. It explores the possibilities of reformulating and reviving the “grammatical” theory, generally ascribed first to Trendelenburg. The paper brings two new perspectives to the grammatical theory: that of Aristotle’s own theory of syntax and that of contemporary linguistic syntax and semantics. I put forth a provisional theory of Aristotle’s categories in which (1) I propose that the Categories sets forth a theory (...) of lexical structure, with the ten categories emerging as lexical or semantic categories, and (2) I suggest conceptual links, both in Aristotle’s writings and in actuality, between these semantic categories and certain grammatical inflections.

This work is the first English translation of Scotus's commentary on Aristotle's Quaestiones super Praedicamenta. Although there are numerous Latin commentaries on Aristotle's Categories, Scotus's Questions is one of the few commentaries on the Categories written in the thirteenth century covering all of Aristotle's text, including the often neglected post-praedicamenta, and the only complete Latin commentary available in English. Moreover, unlike many of the commentaries, Scotus's text is one of the last commentaries to be written (...) before the nominalist reduction of the categories to substance and quality. The question format allows Scotus a great deal of liberty to discuss the categories in detail, as well as matters that are only remotely raised by the text. Altogether, the forty-four questions cover the following subjects: questions 1-4 are prolegomena to the work itself and raise the question of its subject matter as well as whether there can be a science of the categories; questions 5-8 deal with equivocals, univocals, and denominatives; questions 9-11 discuss Aristotle's two rules regarding predication and the sufficiency of the categories; questions 12-36 discuss the four main categories treated by Aristotle, namely, substance, quantity, relation, and quality; and the remaining eight questions discuss the post-praedicamenta.

In his Categories, Aristotle details the kinds of being that exist, along with what can be understood and predicated of existing things. Most notably within this work, Aristotle advances a set of ten, top-level categories that can be used to classify all kinds of being. Even today, the influence of the Categories is felt in many domains, particularly in knowledge organization (KO). Here, Aristotle’s Categories bear deep, long-standing connections with works examining categorization, subject analysis, and theory (...) of classification. Though its relation to ontology might seem obvious, connections to KO perspectives on knowledge organization systems (KOSs) and ontological modeling are curiously lacking. The aim of this work is to offer a re-examination of the Categories as a KOS, particularly through the lens of the KO field’s understandings of ontology. Utilizing Zeng’s classification of KOSs as a theoretical framework, this study draws parallels between the first two sections of the Categories and the defining features of ontologies and offers an initial ontological model of this work. The results of this re-examination stand to offer a new view of a fundamental work in the KO canon, draw further connections between past and present perspectives in KO, and further contribute to the theoretical grounding of contemporary KOS research and practice.

The ancient commentators remain the last body of important Greek writings to be translated into any modern language and this series under the general editorship of Richard Sorabji meets this need. The present volume is especially important both because of its intrinsic interest and because through Porphyry the Categories became a basic textbook of logic with the Neoplatonic school.

"In his discussion of Quality, Aristotle reports a debate on whether justice admits of degrees, or whether only the possession of justice does so. Simplicius reports the further development of this controversy in terms of whether justice admits a range or latitude (platos). This debate helped to inspire the medieval idea of latitude of forms, which thus goes back much further than is commonly recognized - at least as far in the past as Plato and Aristotle."--BOOK JACKET.

I attempt to answer the question of what Aristotle's criteria for 'being a substance' are in the Categories. On the basis of close textual analysis, I argue that subjecthood, conceived in a certain way, is the criterion that explains why both concrete objects and substance universals must be regarded as substances. It also explains the substantial primacy of concrete objects. But subjecthood can only function as such a criterion if both the subjecthood of concrete objects and the subjecthood (...) of substance universals can be understood as philosophically significant phenomena. By drawing on Aristotle's essentialism, I argue that such an understanding is possible: the subjecthood of substance universals cannot simply be reduced to that of primary substances. Primary and secondary substances mutually depend on each other for exercising their capacities to function as subjects. Thus, subjecthood can be regarded as a philosophically informative criterion for substancehood in the Categories. (shrink)

This new study, an updated version of the author's doctoral dissertation, is a detailed investigation of Porphyry's one extant commentary on Aristotle's Categories and Plotinus' critique of Aristotle's doctrine of categories in "On the Kinds of Being". Evangeliou's investigation is limited by the fact that Porphyry's work was written for the student in an elementary "question and answer" format, yet Evangeliou is still able to decipher his general approach to Aristotle, which is respectful and conciliatory. In (...) stark contrast is Plotinus' work, which makes little attempt to interpret Aristotle in a generous manner and rejects most of his doctrine of categories. (shrink)

I argue there are two ways predication relations can hold according to the Categories: they can hold directly or they can hold mediately. The distinction between direct and mediated predication is a distinction between whether or not a given prediction fact holds in virtue of another predication fact’s holding. We can tell Aristotle endorses this distinction from multiple places in the text where he licenses an inference from one predication fact’s holding to another predication fact’s holding. The best explanation (...) for each such inference is that he takes some predication facts to be mediated by others. Once the distinction between direct and mediated predication has been explained and argued for, I show how it can help solve a persistent problem for the traditional view of non-substantial particulars in the Categories—that is, the view that non-substantial particulars are particular in the sense of being non-recurrent. Along with vindicating the traditional view, the direct/mediated predication distinction gives us a distinctive way of understanding what it is for something to be recurrent (or non-recurrent) as well as a better understanding of Aristotle’s broader commitments in the Categories as a whole.

In this paper I investigate Aristotle’s account of predication in Topics I 9. I argue for the following interpretation. In this chapter Aristotle (i) presents two systems of predication cutting across each other, the system of the so-called four ‘predicables’ and of the ten ‘categories’, in order to distinguish them and explore their mutual relationship. I propose a semantic interpretation of the relationship between them. According to this reading, every proposition formed through a predicable constitutes at the same time (...) a predication according to one of the ten categories, and, consequently, signifies one of them, expressing one of the predicative relationship conveyed by them. Further, Aristotle (ii) explains the predicative connection between these two systems and the ten items signified by the ‘things said without any combination’ enumerated in Chapter 4 of the Categories, whose list is almost identical with that of categories in Top. I 9, with the only exception of their first members. (shrink)

This volume, surveying a narrow topic over a long expanse of time, is comprised of selections from a trio of international conferences on the title theme. It is an expensive book, but even its most valuable articles are marred by slovenly editing.Börje Bydén’s contribution begins the survey in Byzantium. By linking Photios’s (apparently) original criticism of Aristotle to Plotinus, Bydén gives an interesting hint of how neo-Platonism came to permeate Christianity. But Photios seems to have been “ignored by posterity” (31). (...) Bydén’s commendable remedy: more and updated critical editions of texts from Greek scholasticism.

Recent theorizing has emphasized the concept of "difference" and how its normative deployment orders our knowledge of the world. This ethical determination of how we know, however, is only half of a loop as difference has epistemological roots. It is precisely the concept '.s inherent connection to the epistemological demand that we must be certain of what we know that underprops it as a contemporary problematic. This demand is basic to philosophy since ancient times. We find it, for example, in (...) the late Platonic dialogues Theaetetus and Sophist as Plato endeavors to define and account for knowledge and true belief We also find this in Aristotle '.s Categories, which not only underpins his other philosophical works, but also founds the categorialism still current in philosophical thinking. We can think of categorial thinking as defining and structuring what we can know. And insofar as our knowledge guides our practice, categorial thinking also defines and structures our reality. In this essay, I perform a simple content analysis of the Categories. The aim is to look for difference and its variants, to count how many times they appear, to identify the general and specific contexts of their appearance, to find related terms and concepts in the specific context of the sentences that they appear in. The essay's analyses try to find explanations as to what Aristotle's concept of difference is, as to what Aristotle think of it as it appears in various contexts in the Categories, as to how it reflects the structure of our knowledge of the world, and as to how it likewise reflects the manner by which we attempt to structure or order our world.
