This paper deals with the doctrine of transubstantial change advocated by Mulla Sadra in which substances as well as accidents are thought to be in constant and gradual change. Against Aristotle’s doctrine of accidental change, Mulla Sadra argues that no stable ground can bring about change and since substance is renewable it cannot carry identity of a changing existent. Here we investigate whether identity is possible or not. If it is possible then what becomes a ground for establishing identity of (...) changing substances. (shrink)

A reply to Arda Denkel's argument that it is not possible to have matter without objects. I argue that the argument assumes that having a 'form' is being sufficient for the existence of an object, which the opponent should not be thought to grant.

Consider a circle and a pair of its semicircles. Which is prior, the whole or its parts? Are the semicircles dependent abstractions from their whole, or is the circle a derivative construction from its parts? Now in place of the circle consider the entire cosmos (the ultimate concrete whole), and in place of the pair of semicircles consider the myriad particles (the ultimate concrete parts). Which if either is ultimately prior, the one ultimate whole or its many ultimate parts?

I demonstrate that Deleuze's identification of Aion as an empty form offers a fascinating model of temporality that prioritises variation. First, I suggest that Deleuze's identification of time as an empty form is supported by ancient Greek and Gnostic concepts of the relation of Aion and Chronos. From Plato, through Aristotle, to Plotinus the concept of time undergoes substantive revision, in the sense that temporal measurement becomes removed from the measurement of existent entities. This gradual untethering of time from movement (...) gives rise to the development of the concept of eternity as an ontologically comprehensive mode of time that is devoid of content. It is here, with Deleuze's reading of the Platonic cosmology, that we see the first hints of the suggestion that Aion is involved with ontogenesis. Eternity is characterised as: a temporal ‘all’ that is non-reducible to the determinacy implied by any particular temporally localised existent or temporal series ; that which tends towards a diversity of possible states of affairs. Perhaps one of the most interesting aspects in the long history of Aion is that – in the ancient world – it was used in magical incantations. For the Gnostics and Oracles, Aion was a deity, and a potent one at that. From the Gnostic papyri, we get a vision of Aion as a force which enjoys eternal realisation. I suggest that the papyri conjure an image of Aion as a deity that is liberated from time, in the sense that it enjoys a neutrality with respect to the movements of any particular entity or group of entities – a form, in the most general sense of the term. Then, to clarify this mercurial aspect of an empty form of time, I elaborate on a complex analogy between Aion and Deleuze's concept of an ‘ideal game’ – an analogy that Deleuze specifies through reference to Fitzgerald and Borges. The claim is that Aion is an analogue of an ideal game in the sense that both share essential properties. Both Aion and the ideal game involve the multiplication of chance. Finally, I suggest that the differential aspects of Aion imply that it is pure variability; something which can be illustrated through a differential equation. These yield the suggestion that Aion enjoys realisation as an ontogenetic force. I further claim that ontogenetic forces may enjoy expression as the content of literature and mathematics. In concrete terms, temporality is involved in the creation of existent entities, which may be illustrated as various types of continuous multiplicity. (shrink)

Extensionalism, as I understand it here, is the view that physical reality consists exclusively of extensional entities. On this view, intensional entitities must either be eliminated in favor of an ontology of extensional entities, or be reduced to such an ontology, or otherwise be admitted as non-physical. In this paper I argue that extensionalism is a misguided philosophical doctrine. First, I argue that intensional phenomena are not confined to the realm of language and thought. Rather, the ontology of such phenomena (...) is intimately entwined with the ontology of properties. After providing some evidence to the popularity of extensionalism in contemporary analytic philosophy, I investigate the motivating reasons behind it. Considering several explanations, I argue that the main motivating reason is rooted in the identification of matter with extension, an identification which is one of the hallmarks of the mechanistic conception of nature inherited from the founding fathers of our modern scientific outlook. I then argue that such a conception is not only at odds with a robust ontology of properties but is also at odds with our best contemporary physics. Rather than vindicating extensionalism contemporary science undermines the position, and the lesson to be drawn from this surprising fact is that extensionalism needs no longer be espoused as a regulative ideal of naturalistic philosophy. I conclude by showing that the ontological approach to intensional phenomena advocated throughout the paper also gains support from an examination of the historical context within which ‘intension’ was first introduced as a semantic notion.

According to Kant, the division of the categories “is not the result of a search after pure concepts undertaken at haphazard,” but is derived from the “complete” classification of judgments developed by traditional logic. However, the sorts of judgments that he enumerates in his table of judgments are not all ones that traditional logic has dealt with; consequently, we must say that he chose the sorts of judgments in question with a certain intention. Besides, we know that his choice of (...) judgments and categories is strongly influenced by certain views of natural science that he fully accepts. For this reason, his argumentations are sometimes seriously inconsistent. As to Kant’s argumentations of categories, many problems have already been pointed out, but in this paper, I take up the categories of quantity and quality once more, and make clear his argumentations’ hidden logic and its distortion from the point of view of the history of logic and natural science. First, I confirm that there are non-negligible problems in his explanation to the effect that his derivation of the categories of quantity and quality is based on the quantity and quality of judgments. Next, I reconsider the meaning of his treating the categories of quantity and quality as pure concepts of the understanding. Finally, I conclude that by having recourse to the categories of quantity and quality Kant tried unjustly to apriorize the distinction between the “extensive magnitude” and “intensive magnitude” that has a long formational history since Aristotle.

This essay offers an original interpretation and defense of the doctrine of flux, as it is presented in Plato’s Theaetetus. The methodology of the paper’s analysis is in the style of rational reconstruction, and it is highly analytic in scope, in the sense that I will focus on the text itself, and only on certain parts of it too, while ignoring the rest of Plato’s extensive corpus, and without worrying about whether, how, and to what extent the interpretation of the (...) view coheres well with the other elements of the secret doctrine view discussed in the dialogue, as well. In the first part of the essay, I’ll offer my interpretation of the doctrine. Then, in the second part of the essay, I’ll examine two potential criticisms of the doctrine, including Socrates’s infamous linguistic paradox, and show how my interpretation of Heraclitean flux metaphysics is able to circumvent both.

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)

Kit Fine, the leading proponent of the metaphysical project of grounding theory, has offered a number of potentially devastating objections to truthmaker theory, the branch of metaphysics dedicated to exploring the ontological grounds for truths. In this paper I show what presuppositions about truthmaker theory Fine’s objections are based upon, and why they are false. I discuss four objections that Fine raises, and demonstrate how truthmaker theorists may respond to them. I then showcase the positive contribution that truthmaker theory can (...) make to metaphysics, including its ability to speak to a core metaphysical topic (the ontological grounds for truths) that Fine’s approach to grounding must ultimately remain silent on. I conclude by exploring what I take to be the best option when it comes to understanding how truthmaking and grounding fit together. (shrink)

This article applies Ayn Rand's insights in metaphysics and epistemology to the question What is a corporation? Historically, there have been three main answers: the fictional entity theory, the aggregate theory, and the real entity theory. Drawing principally upon Rand's discussion of the nature of entities in her epistemology workshops, this article proposes a fourth possibility. The preceding theories assume that if a corporation is an entity it must exist as a separate entity. The theory defended in this article challenges (...) this assumption, and considers the implications for the moral and political status of corporations. (shrink)

This article identifies several critical problems with the last 30 years of research into hostile communication on the internet and offers suggestions about how scholars might address these problems and better respond to an emergent and increasingly dominant form of online discourse which I call ‘e-bile’. Although e-bile is new in terms of its prevalence, rhetorical noxiousness, and stark misogyny, prototypes of this discourse—most commonly referred to as ‘flaming’—have always circulated on the internet, and, as such, have been discussed by (...) scholars from a range of disciplines. Nevertheless, my review of this vast body of literature reveals that online hostility has historically posed a number of conceptual, methodological, and epistemological challenges due to which scholars have typically underplayed, overlooked, ignored, or otherwise marginalised its prevalence and serious ethical and material ramifications. Fortunately, lessons learned from my analysis suggests promising approaches for future research into this challenging form of new media discourse. (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.

The main concern of Agamben's work, prior to the Homo Sacer project, is how to understand the existence of or potentiality for language. Contemporary philosophy casts language as the unsayable presupposition of discourse. Agamben criticises this as an incomplete nihilism that remains within the horizon of metaphysics, and attempts to think the experience of language without an unsayable ground. I examine Agamben's critique of the role of the ineffable in the theory of the subject, and in the thought of Heidegger (...) and Derrida. I contrast this with his account of infancy as an experience that fully assumes the groundlessness of language. (shrink)

Traditionally, the so-called exemplification or the relation between the particular and the universal has been one of the three central problems making up the classical problem of universals: (1) What is a particular? (2) What is a universal? (3) What is the relation between the particular and the universal? I used the expression “classical problem of universals” instead of “the problem of universals” since the classical formulation of the problem could be said to contain a questionable assumption, namely that substance (...) should be the bearer “in” which are the entities of (other) categories. Under these circumstances, a neutral approach to the problem of universals could consist in reformulating the three problems of the classical problem as follows: (4) What is the fundamental bearer of categories? (5) What categories are there? (6) What is the relation between the fundamental bearer and the categories? My purpose in this paper is to answer the latter three questions. In order to accomplish this task, I shall discuss the views of two leading figures in substance-ontology, Aristotle and Jonathan Lowe, and the views of two leading figures in fact-ontology, Gustav Bergmann and Reinhardt Grossmann. I shall answer the first question by claiming that the fundamental bearer of categories is facts; the second, by pointing out that it depends on the answer to the previous one; and the third, by showing that the relation between the fundamental bearer and the categories is the one between facts and its constituents, not between a substance or particular and its accidents or properties. In this connection, I shall argue that the “in” of property exemplification should be categorially reconstructed in order for entities other than properties, say, particulars, relations, connectives, numbers, and even facts, to be “in” facts. This categorial reconstruction will also argued for with respect to the Principle of Exemplification. (shrink)

Chrysippus claims that some propositions perish. including some true conditionals whose consequent is impossible and antecedent is possible, to which he appeals against Diodorus?s Master Argument. On the standard interpretation. perished propositions lack truth values. and these conditionals are true at the same time as their antecedents arc possible and consequents impossible. But perished propositions are false, and Chrysippus?s conditionals are true when their antecedent and consequent arc possible, and false when their antecedent is possible and consequent impossible. The claim (...) of the Master Argument that Chrysippus rejects, then, is stronger ihan usually supposed. (shrink)

In Aristotle’s account of change, lacking a form is called privation (Physics I.7 191a14). For example, someone takes on the form of being musical only from previously having the privation of being unmusical. However, he also states that “shape and nature are spoken of in two ways, for the privation too is in a way form” (Physics II.1 193b19). I will demonstrate that these seemingly contradictory statements are not actually in tension. Since all perceptible matter must be enformed, we would (...) have trouble discussing things that have yet to undergo generation, like menstrual fluid, and things that have undergone corruption, like corpses, if we did not cite the privation as a sort of form. I will argue that, given his commitment to hylomorphism, Aristotle is committed to privation being a form in a qualified sense. It cannot be a form in an unqualified sense because privation often spoils the matter such that it can no longer be reformed. The fact of the matter is we cannot draw a bright line between privation and form because the two are contraries and can be said to hold to different degrees at different points on a spectrum.

Kant’s philosophy of mathematics presents two fundamental problems of interpretation: (1) Kant claims that mathematical truths or “judgments” are synthetic a priori; and (2) Kant maintains that intuition is required for generating and/or understanding mathematical statements. Both of these problems arise for us because of developments in mathematics since Kant. In particular, the axiomatization of geometry--Kant’s paradigm of mathematical thinking--has made it seem to some commentators as, for example, Russell, that both (1) and (2) are false (Russell 1919, p. 145).2 (...) If virtually all of mathematics, including geometry, is axiomatizable, it would seem that mathematics results in analytic judgments that are totally independent of sensibility, the source, according to Kant, of intuition. In this paper I will address both of these difficulties. I shall argue that Kant’s understanding of both “synthetic” and “intuition” make his position immune to these criticisms. (shrink)

Compositionality has been a central concept in linguistics and philosophy for decades, and it is increasingly prominent in many other areas of cognitive science. Its status, however, remains contentious. Here, I reassess the nature and scope of the principle of compositionality (Partee, 1995) from the perspective of psycholinguistics and cognitive neuroscience. First, I review classic arguments for compositionality and conclude that they fail to establish compositionality as a property of human language. Next, I state a new competence argument, acknowledging the (...) fact that any competent user of a language L can assign to most expressions in L at least one meaning which is a functiononlyof the meanings of the expression's parts and of its syntactic structure. I then discuss selected results from cognitive neuroscience, indicating that the human brain possesses the processing capacities presupposed by the competence argument. Finally, I outline a language processing architecture consistent with the neuroscience results, where semantic representations may be generated by a syntax‐driven streamandby an “asyntactic” processing stream, jointly or independently. Compositionality is viewed as a constraint on computation in the former stream only. (shrink)

Abstract In this paper I propose a mereological account of ordinary macro-events of experience that is based on two central features of these entities, namely their spatio-temporal character, and their status as things that belong to event-kinds. I argue that, from the perspective of descriptive metaphysics, these features must be incorporated in the analysis of the part-whole relations of events, and I show the steps involved in achieving this task. Furthermore, I argue that the program initiated here is quite promising: (...) the analysis of event-part that I propose stands up quite well against the more serious objections, and the apparatus I provide for the mereological conditions of events can be easily modified to yield similar conditions for material objects.

The self/non-self model, first proposed by F.M. Burnet, has dominated immunology for 60 years now. According to this model, any foreign element will trigger an immune reaction in an organism, whereas endogenous elements will not, in normal circumstances, induce an immune reaction. In this paper we show that the self/non-self model is no longer an appropriate explanation of experimental data in immunology, and that this inadequacy may be rooted in an excessively strong metaphysical conception of biological identity. We suggest that (...) another hypothesis, one based on the notion of continuity, gives a better account of immune phenomena. Finally, we underscore the mapping between this metaphysical deflation from self to continuity in immunology and the philosophical debate between substantialism and empiricism about identity.

In this paper the authors develop a logic of concepts within a mathematical linguistic theory. In the set of concepts defined in a belief system, the order relationship and Boolean algebra of the concepts are considered. This study is designed to obtain a tool, which is the metatheoretical base of this type of theory.

In 1498 Cajetan published a short book, On the Analogy of Names, which is often regarded as a masterly summary of Aquinas's doctrine of analogy. It opens in the very first paragraph with an attack on three views of the concept of being (ens): first, that it is a disjunction of concepts; second, that it is an ordered group of concepts; and third, that it is a single, separate concept which is unequally participated by substances and accidents. A number of (...) questions immediately spring to mind. Why are concepts being discussed when analogy is said by Cajetan to be a theory of language? What is meant by ‘concept’? Who held the views under attack and why? So far as I can tell, the extensive literature on both Aquinas and Cajetan offers no satisfactory answers to these questions. (shrink)

I raise a puzzle case for “cluster” accounts of natural kinds—the homeostatic property cluster and stable property cluster accounts, especially—on the basis of their expected treatment of the metaphysics of certain disease kinds. Some kinds, I argue, fail to exhibit the co-instantiated property clusters these cluster views take to be constitutive of natural kinds. Some genetic diseases, for example, have archetypical instances with few or none of the pathological processes or symptoms associated with the kind: their instances are typified by (...) a single dispositional property. I dub such kinds ‘amorphic’, owing to their limited morphology, and try out a number of ways in which these kinds might be treated in terms of property clusters, adapting responses cluster theorists have offered to the problem of polymorphic species. Finding these responses wanting, I conclude that cluster accounts are unlikely to be the best account of the metaphysics of amorphic kinds. (shrink)

The aim of this paper is to offer two novel solutions to two perennial problems of categorial ontology, namely, the problem of the categorial structure: how are the categories related to one another? And the problem of categorial completeness: how is the completeness of a proposed list of categories justified? First, I argue that a system of categories should have a structure such that there is a most basic category that is a bearer of all other categories and that has (...) what I shall call “combinatorial conditions”. To do so, I compare this approach to categorial structure with the approaches given by substantialist, mereological, factualist, and geo ontologies. Second, I argue that the problem of categorial completeness is only a problem for certain ontologies. In this connection, I explore views on categorial completeness proposed by substantialists and geo-ontologists. Lastly, I conclude that factualism does a better job of accounting for categorial structure and categorial completeness than other categorial ontologies. (shrink)

Behavioral economics is the latest trendy form of economics. Increasingly theorists are advocating using behavioral economics to do normative ethics or claiming that the behavioralists’ findings render normative claims otiose. I argue in this paper that we should be extremely wary when it comes to accepting any such normative pronouncements. I argue that behavioral economics: (a) minimizes and/or misunderstands the role that character and architectonic life goals play in accounting for the why of ethical behavior, (b) fundamentally misconceives human practical (...) rationality, (c) often unduly narrows the range of human action and choice, (d) misleadingly assumes that options are merely given to us rather than generated by us in accordance with our character, (e) is parasitic upon normative ethics, (f) results in an unhelpful ad hoc approach to ethical thinking, which is unlikely to prove all that useful and may even dangerously mislead ordinary agents or those who operate corporate compliance programs and who seek to improve corporate cultures, and (g) ignores the key role played in ethical behavior by meso‐ and macro‐factors.

This paper addresses the role of categories and dimensions in the classification of psychopathology. While psychopathology does not sort itself out neatly into natural categories, we do find rough, symptom-based groupings that, through refinement, become diagnostic categories. Given that these categories suffer from comorbidity, uncertain boundaries, and excessive “unspecified disorder” diagnoses, there has been a move toward refining the diagnoses with dimensional measures. The paper traces efforts both to improve the diagnostic categories with validators that allow at least partial validity (...) and to introduce dimensional measures into the diagnostic manual. Drawing from the philosophical pragmatism of Charles Sanders Peirce, William James, and John Dewey, which emphasizes the practical, effect-sensitive consequences of a theory along with an emphasis on empirical evidence and the progressive, probabilistic character of knowledge, the paper argues that these efforts must be guided both by scientific validity and clinical utility.

Simplicius in Cat. 12,10-13,12 presents an interesting justification for the study of Aristotle's Categories, based in Neoplatonic psychology and metaphysics. I suggest that this passage could be regarded as a testimonium to Iamblichus' reasons for endorsing Porphyry's selection of the Categories as an introductory text of Platonic philosophy. These Iamblichean arguments, richly grounded in Neoplatonic metaphysics and psychology, may have exercised an influence comparable to Porphyry's.

In this paper I adopt Aquinas’ explanation of passivity and activity by means of acts remaining in the agent and acts passing over into external matter. I use it to propose a divide between immanent-type and transcendent-type acts. I then touch upon a grammatical distinction between three kinds of verbs. To argue for the activity and passivity of affectivity I refer to the group that includes acts of transcendent-type and whose verbs in both voices possess affective meaning. In the end (...) I focus on cases in which an act of affective f-ing is mirrored in its object as being affectively f-ed. (shrink)

This paper is a case study of how a few short lines in two of Aristotle’s logical works were read in the thirteenth century. I shall begin with a quick look at Aristotle’s own remarks about equivocation in the Categories and the Sophistical Refutations, as they were transmitted to the West by Boethius’s translations. I shall continue with an analysis of the divisions of equivocation and analogy to be found in an anonymous commentary, on the Sophistical Refutations written in Paris (...) between 1270 and 1280. I have chosen this author’s work to focus on, because it offers a remarkably full account which brings together the elements found in many other logical works from the second half of the thirteenth century. In the course of my analysis I shall attempt to show the part played by four different sources: the Greek commentators of late antiquity; the new translations of Aristotle’s Physics and Metaphysics; the reception of Arabic works, particularly the commentaries of Averroes; and new grammatical doctrines, notably that of modi significandi. At the same time, I hope to throw some light on the development of the doctrine of analogy as it was understood by late thirteenth-century logicians. (shrink)
