Aristotle: Categories

Modern commentators recognize the irony of Aristotle’s Categories becoming a central text for Platonic schools. For similar reasons, these commentators would perhaps be surprised to see Aquinas’s In VII Metaphysics, where he apparently identifies the secondary substance of Aristotle’s Categories with a false Platonic sense of “substance” as if, for Aristotle, only Platonists would say secondary substances are substances. This passage in Aquinas’s commentary has led Mgr. Wippel to claim that, for Aquinas, secondary substance and essence are not the same (...) thing and that Aristotle’s notion of essence is absent from the Categories. This paper—by closely analyzing the apparently contradictory divisions of “substance” in Aquinas’s In V and VII Metaphysics—shows that essence and secondary substance are not altogether distinct for Aquinas. Moreover, when the Categories is viewed by Aquinas as a work of logic, it is found largely to cut across the disputes between Platonism and Aristotelianism. (shrink)

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)

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 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)

The principate of Augustus coincided with a surge of interest in the short Aristotelian treatise which we now entitle Categories, contributing to its later installation at the outset of the philosophical curriculum and its traditional function as an introduction to logic. Thanks in part to remarks made by Plutarch and Porphyry , the origin of this interest has often been traced to Andronicus of Rhodes: his catalogue and publication of the Aristotelian corpus began with the Categories and may have drawn (...) fresh attention to a previously obscure treatise. But the later Neoplatonic sources name several other philosophers who also discussed the Categories and played an important role in crafting its interpretation during the first centuries of our era. For example, the Neoplatonist Simplicius discusses the views of Stoics and Platonists who questioned the Categories' value as a treatment of grammar or ontology, while others defended its usefulness as an introduction to logic. These early debates, as these later sources suggest, exercised a lasting influence on the shape of subsequent philosophy and philosophical education within and beyond the Aristotelian tradition.

In the Categories Aristotle defined substance as that which is neither predicable of nor in another. In saying that a substance is not predicable of another, Aristotle meant to exclude genera and species from the category substance. Aman is a substance but not man. In saying that a substance is not in another, Aristotle meant to exclude property particulars from the category. A man is a substance, not his color. The Categories treats substances as simples. Though a particular substance, Bucephalus (...) the horse, has parts, it is nevertheless a single entity in the category substance and, hence, incomplex in the way a black thing or a running man are not. Black things and runners are complex because they are aggregates of substances and property particulars. Even if a horse is one substance and, thus, an entity, a horse is made of parts and one may wonder how it is related to its parts, as well as how its being made of parts coheres with the definition of substance given in the Categories.

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.

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.

J'examine le statut et la fonction des Catégories dans la philosophie d'Aristote.Le traité n'appartient ni à la philosophie première, ni même à la philosophie tout court, mais à la dialectique. Il ne s'agit pas d'une « discussion dialectique » de l'être, mais plutôt de dialectique en tant que tel : ce traité forme un ensemble avec les Topiques, qui a pour but d'aider le questionneur dans un débat dialectique à décider si le terme donné peut tomber sous la définition proposée (...) ou sous le genre proposé. Bien qu'il y ait un emploi philosophique des Catégories, tout comme de la dialectique en général, l'opposition prétendue entre la théorie de la substance des Catégories et celle de la Métaphysique est fondée sur une méconnaissance des buts différents des deux traités. I examine the status and function of the Categories in Aristotle's philosophy.The work does not belong to « first philosophy, » or indeed to philosophy at all, but to dialectic; not as a « dialectical discussion » of being, but in the strict sense that it is intended, together with the Topics, to help the dialectical disputant to decide whether a given term can fall under a proposed definition or a proposed genus. Although the Categories, like dialectic in general, has uses in philosophical argument, the supposed opposition between the accounts of substance in the Categories and in the Metaphysics depends on a misunderstanding of the different aims of the two works.

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 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)

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)

There is a dispute as to what sort of entity non-substantial individuals are in Aristotle's Categories. The traditional interpretation holds that non-substantial individuals are individual qualities, quantities, etc. For example, Socrates' white is an individual quality belonging to him alone, numerically distinct from (though possibly specifically identical with) other individual colors. I will refer to these sorts of entities as 'individual instances.' The new interpretation1 suggests instead that non-substantial individuals are atomic species such as a specific shade of white that (...) is indivisible into more specific shades. On this view, non-substantial individuals are what we would call universals2 which can be present in different individual substances, but are labelled 'individuals' by Aristotle because, like individual substances, there is nothing they are said of.3 In this paper I will defend the traditional account by attempting to show that it is supported by the slender textual evidence that is available. I will begin by stating three serious objections to the traditional interpretation. Next I will show that in works later than the Categories Aristotle accepted individual instances of properties of the sort found in the Categories by the traditional interpretation. Finally, I will set out the evidence that supports the traditional interpretation and answer the three objections. (shrink)

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)

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.

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)

The opening chapter of the Categories fails to reveal whether it is introducing a grammatical, a logical, or a metaphysical treatise. It deals with equivocals and univocals and ends with a definition of paronyms. The definition of paronyms is given in purely grammatical terms. Paronyms derive their name from an identical source with a difference only in case ending, as bravery and the brave, grammar and the grammarian. The second chapter, however, proceeds to state that an expression can be either (...) complex or simple--complex like "a man runs," or simple like "man" or "runs." Then it immediately passes over to beings. Of the things that are, it states, some are asserted of a subject, but are not in any subject. The example given is that "man" is asserted of a particular man. To supply for Aristotle a current instance of what is here meant, one might use the sentence "Bertrand Russell is a man." This type of statement, to take the Aristotelian text literally, is dealing with beings and is asserting something of a subject. What is asserted, "man," is not in any subject even though it is asserted of a subject. In other words, the logically proper name "Bertrand Russell" denotes a substance and not an accident. (shrink)

The precise position to be assigned to the Categories in the Aristotelian system has always been somewhat of a puzzle. On the one hand, they seem to be worked into the warp of its texture, as in the classification of change, and Aristotle can argue from the premiss that they constitute an exhaustive division of the kinds of Being . On the other hand, both in the completed scheme of his logic and in his constructive metaphysic they retire into the (...) background, giving place to other notions, such as causation, change, actuality and potentiality. Investigation has, moreover, been hampered, especially in Germany, by attempts to correlate them with the Kantian Categories, with which they have obvious points of contact. But Kant's formal a priori concepts by which the mind makes for itself a world, to use Mr. Bosanquet's phrase, imply an attitude to knowledge and reality so utterly opposed to the Aristotelian that the comparison has tended to confusion rather than elucidation. Scholars now realize better that the Aristotelian Categories can only be understood in connexion with the problems of Aristotle's own age. (shrink)
