Ontological Categories

Neo-Aristotelian metaphysics comprises the topics in contemporary metaphysics which bear similarity to the interests, commitments, positions and general approaches found in Aristotle. Despite the current interest in these topics, there is no monograph length general introduction to the methodology and themes of neo-Aristotelian metaphysics. One underdiscussed question concerns demarcation: what unifies the topics that fall under the heading of neo-Aristotelianism? Contemporary metaphysicians who might be classified as ‘neo-Aristotelians’ tend towards positions reminiscent of Aristotle’s metaphysics—such as sympathy with grounding, substance ontology, (...) non-modal construals of essence, hylomorphism, causal powers, presentism, endurantism and agent causation. However, prima facie it seems that one might hold any one of these positions while rejecting the others. What perhaps unifies a neo-Aristotelian approach in metaphysics, then, is not a shared collection of positions so much as a willingness to engage with Aristotle and to view this historical figure as providing a fruitful way of initially framing certain philosophical issues. However, also missing in the literature is a sustained methodological discussion on the contribution historical scholarship on Aristotle might make to contemporary metaphysics, and the contribution contemporary metaphysics might make to historical scholarship. Little hinges on whether what gets labelled neo-Aristotelian metaphysics is or isn’t Aristotle’s metaphysics. But historical scholarship is useful within contemporary metaphysics not merely to to apply historically accurate labels to positions. There are topics where the historical and contemporary issues dovetail in mutually rewarding ways: serious engagement with the history of philosophy can yield living philosophical rewards for today’s metaphysician; and serious engagement with contemporary philosophy can yield exegetical rewards for the historian. The monograph will introduce these methodological issues, and then turn to case studies on ontological dependence, substance ontology, category theory and hylomorphism. These are all topics where there is robust debate within both Aristotle studies and contemporary metaphysics, and topics where historians and metaphysicians are working somewhat in isolation from each other. The aim of the monograph is to make the relevant exegetical questions accessible to contemporary metaphysicians, and the corresponding contemporary topics accessible to historians. The target audience includes researchers, graduate students and advanced undergraduates, in both metaphysics and Aristotle studies. (shrink)

Arguments for a theory about the nature of the ontological categories, the relations that determine them and their epistemic role in the construction of different kinds of limited, but true knowledge of reality in itself.

In this talk, I propose a new account of ontological form, formal ontological relations, modes of being and hence of specifying the subject matter of metaphysics.

There is an emerging view according to which countability is not an integral part of the lexical meaning of singular count nouns, but is ‘added on’ or ‘made available’, whether syntactically, semantically or both. This view has been pursued by Borer and Rothstein among others in order to deal with classifier languages such as Chinese as well as challenges to standard views of the mass-count distinction such as object mass nouns such as furniture. I will discuss a range of data, (...) partly from German, that such a grammar-based view of countability receives support when applied to verbs with respect to the event argument position. Verbs themselves fail to specify events as countable in English and related languages; instead countability is made available only by the use of the event classifier time or else particular lexical items, such as frequency expressions, German beides ‘both’, or the nominalizing light noun -thing. The paper will not adopt or elaborate a particular version of the grammar-based view of countability, but rather critically discuss existing versions and present two semantic options of elaborating the view.

Substance dualism is the view that there are two fundamentally different kinds of substances: physical and mental. By contrast, according to property dualism there is only one kind of substance (physical) but two fundamentally different kinds of properties: physical and mental. Property nominalism is the view that there are neither repeatable nor non-repeatable fundamentally predicable entities (i.e. neither universals nor tropes) and that things being a certain way or being related in a certain way must ultimately be accounted for in (...) terms of concrete particulars. In this paper, we consider a number of different kinds of property nominalism and argue that none of them sits well with property dualism. We pay special attention to the question of what it could mean for a property to count as mental given different nominalistic accounts of properties. Our conclusion is that property nominalism and property dualism are not a stable match. This is surprising, since property dualism has usually been understood as a thesis that is neutral about the nature of fundamental ontological categories and the relation between them. (shrink)

Does Anne Conway (1631–79) hold that the created world consists of a single underlying substance? Some have argued that she does; others have argued that she is a priority monist and so holds that there are many created substances, but the whole created world is ontologically prior to each particular creature. Against both of these proposals, this article makes the case for a substance pluralist interpretation of Conway: individual creatures are distinct substances, and the whole created world is not ontologically (...) prior to the individual creatures that compose it. The basic argument for such a view draws on Conway's claims about the freedom and moral responsibility of individual creatures. The pluralist reading is straightforwardly compatible with these claims, while the monistic readings are not. (shrink)

What the Sorites has to tell us is a simple truth regarding our categories. It appears to saddle us with something other than a simple truth—something worse, a contradiction or a problem or a paradox—only when we insist on viewing it through a discrete logic of categories. Discrete categories and discrete logic are for robots. We aren’t robots, and the simple truth is that we don’t handle categories in the way any discrete logic would demand. For us non-robots, what the (...) Sorites has to offer is a straightforward truth regarding how incapable robots and their logic are of handling categories like ours. (shrink)

Wiredu uses the term ‘empiricalism’ to characterize a mode of thinking that is essentially empirical in orientation but admits non-transcendental metaphysical categories and existents into its systems of thought. Wiredu finds evidence of this mode of thinking in the Akan language. The central question I engage with in this paper is this: what makes empiricalism a plausible system of thought that has universal validity and intelligibility? I argue that the plausibility and universality of empiricalism is evident in Wiredu’s logical and (...) semantic thinking that underpins the theses of empiricalism. Rather than it being an isolated doctrine of Wiredu, the central theses of empiricalism are rooted in, and cast in terms of, his logical and semantic analysis of distinctions such as signification and reference, concept and object, and of his analysis of terms such as ‘existence’. These analyses show that the attractiveness of empiricalism is dependent on theoretical principles other than, and in addition to, the linguistic evidence that Akan provides. (shrink)

Philosophers frequently draw on natural language to motivate properties, numbers, and propositions as objects, and it is generally taken for granted that abstract objects of this sort are well-reflected in natural language and in fact that reference to them in natural language is pervasive In this paper, I will review and modify in a certain way the view I had advanced in Abstract Objects and the Semantics of Natural Language (Moltmann 2013a). This is the view that natural language permits reference (...) to abstract objects only in its periphery, not in its core. Even though reference to abstract objects of the sort of properties, propositions, and numbers is available only in the periphery of language, natural language permits reference to other sorts of abstract objects in its core, in particular abstract artifacts of various sorts.

ABSTRACT: I argue that Sellars’s metaconceptual theory of the categories exemplifies and extends a long line of nominalistic thinking about the nature of the categories from Ockham and Kant to the Tractatus and Carnap, and that this theory is far more central than has generally been realized to each of Sellars’s most famous and enduring philosophical conceptions: the myth of the given, the logical space of reasons, and resolving the ostensible clash between the manifest and scientific images of the human (...) being in the world. Sellars’s distinctive contribution to this longstanding (if currently on the defensive) metaconceptual approach to the nature of ontological categories was to interpret and reconstruct it in terms of his own ‘meaning as use’ or norm-governed inferential role semantics. With these resources Sellars sought to preserve the genuine insights in the ‘realist’ or broadly platonic traditions while simultaneously defending the idea that in the end, as he puts it, “a naturalistic ontology must be a nominalistic ontology” (1980a NAO IV §129).

The social categories to which we belong—Latino, disabled, American, woman— causally influence our lives in deep and unavoidable ways. One might be pulled over by police because one is Latino, or one might receive a COVID vaccine sooner because one is American. Membership in these social categories most often falls outside of our control. This paper argues that membership in social categories constitutes a restriction on human agency, creating a situation of non-ideal agency for many human individuals. -/- However, there (...) are ways to resist the causal influence of social categories, and certain socially marginalized groups can be understood as attempting to do just this. I discuss two instances of social category resistance: gender pronouns and the rights of trans individuals. I suggest that the intentional declaration of gender pronouns (“she/her” or “they/them”) can be understood as an attempt to resist the causal powers of nonconsensual social categorization. Similarly, one among many reasons to support the rights of trans individuals is that their self-declarations of gender identity can be viewed as a reclamation of agency in the face of causal constraints imposed by socially defined and imposed gender categories. This lesson can be generalized to people belonging to a broad range of marginalized groups. (shrink)

Ontologiset kategoriateoriat pyrkivät vastaamaan metafysiikan klassiseen ongelmaan: kysymykseen siitä, mihin eri kategorioihin oliot eli entiteetit jakaantuvat. Olioilla tarkoitetaan tässä mitä tahansa, joka on olemassa. Olevan kategoriat eli ontologiset kategoriat (lyhyesti kategoriat) ovat alustavasti olioiden hyvin yleisiä lajeja. Jäsenyys olioiden kategoriassa ei niinkään kerro sitä, mitä piirteitä oliolla on, vaan sen olemisen tavan ¬– miten se esimerkiksi on tai voi olla maailman rakenneosa. Esimerkkejä mahdollisista kategorioista ovat konkreettiset partikulaariset yksilöoliot (substanssit), ominaisuudet, relaatiot, prosessit, tapahtumat ja joukot. -/- 1.

According to relationism, for Alice to believe that some rabbits can speak is for Alice to stand in a relation to a further entity, some rabbits can speak. But what could this further entity possibly be? Higher-order metaphysics seems to offer a simple, natural answer. On this view (roughly put), expressions in different syntactic categories (for instance: names, predicates, sentences) in general denote entities in correspondingly different ontological categories. Alice's belief can thus be understood to relate her to a sui (...) generis entity denoted by "some rabbits can speak", belonging to a different ontological category than Alice herself. This straightforward account of the attitudes has historically been deemed so attractive that it was seen as providing an important motivation for higher-order metaphysics itself (Prior [1971]). But I argue that it is not as straightforward as it might seem, and in fact that propositional attitudes present a foundational challenge for higher-order metaphysics. (shrink)

a cuestión de si la realidad es homogénea o heterogénea es uno de los debates más antiguos de la filosofía occidental y se repite en prácticamente todas las tradiciones filosóficas del mundo. Hay tres motivaciones principales para adoptar una visión heterogénea de la realidad: para dar cuenta de errores categoriales, para resolver paradojas, y para respetar la aparente heterogeneidad de nuestra experiencia, pensamiento y lenguaje. A continuación, revisaremos cada una de ellas, para después ver los principales retos que enfrenta quién (...) quiera defender una visión plural del ser. (shrink)

Best known for his groundbreaking and influential work in Buddhist philosophy, Mark Siderits is the pioneer of “fusion” or “confluence philosophy", a boldly systematic approach to doing philosophy premised on the idea that rational reconstruction of positions in one tradition in light of another can sometimes help address perennial problems and often lead to new and valuable insights. -/- Exemplifying the many virtues of the confluence approach, this collection of essays covers all core areas of Buddhist philosophy, as well as (...) topics and disputes in contemporary Western philosophy relevant to its study. They consider in particular the ways in which questions concerning personal identity figure in debates about agency, cognition, causality, ontological foundations, foundational truths, and moral cultivation. Most of these essays engage Siderits’ work directly, building on his pathbreaking ideas and interpretations. Many deal with issues that have become a common staple in philosophical engagements with traditions outside the West. Their variety and breadth bear testimony to the legacy of Siderits’ impact in shaping the contemporary conversation in Buddhist philosophy and its reverberations in mainstream philosophy, giving readers a clear sense of the remarkable scope of his work.

Easy Ontologists, most notably Thomasson (2015), argue that ontological questions are shallow. They think that these questions can either be answered by using our ordinary conceptual competence—of course tables exist!—or are meaningless, or else should be answered through conceptual re-engineering. Ontology thus is “easy”, requiring no distinctively metaphysical investigation. This paper raises a two-stage objection to Easy Ontology. We first argue that questions concerning which entities exist are inextricably bound up with “ontological category questions”, which are questions concerning the identity (...) of and differences between kinds of entities. We then argue that ontological category questions do not have trivial answers, are meaningful, and cannot be answered through conceptual re-engineering. Easy Ontology hence does not constitute a comprehensive ontological methodology. While some of ontology might be easy, category questions form a central part of ontology and are not answered easily.

Priority monism is the doctrine that there is exactly one substance: the whole concrete cosmos. This paper develops an objection to priority monism. The objection is that although every substance is necessarily a substance, for the priority monist the cosmos is not necessarily a substance. It follows that the cosmos is not a substance and so priority monism is false. The priority monist's pluralist opponent, I argue, can avoid a parallel objection to her view.

Analytic Philosophy, EarlyView. The method of paraphrasing away apparent ontological commitments is a familiar tool for trimming one's ontology. Even so, I argue that aiming to avoid commitment via paraphrase is unjustified. The reason is the standard motivations for paraphrase rest on implicit yet faulty principles regarding ontological categories and categorization- or so I argue. These results also provide indirect support for a permissivist approach to ontology.

Formal ontology as a main branch of metaphysics investigates categories of being. In the formal ontological approach to metaphysics, these ontological categories are analysed by ontological forms. This analysis, which we illustrate by some category systems, provides a tool to assess the clarity, exactness and intelligibility of different category systems or formal ontologies. We discuss critically different accounts of ontological form in the literature. Of ontological form, we propose a character- neutral relational account. In this metatheory, ontological forms of entities (...) are their standings in internal relations whose holding is neutral on the character of their relata. These relations are “formal ontological relations”. Entities belong to ontological categories because they stand in the same formal ontological relations. We hold a nominalist relationalism about ontological categories and forms. We conclude by showing that our metatheory is useful for understanding categorial fundamentality/non- fundamentality, different formal ontologies, and for unifying metaphysical questions. (shrink)

Ontological pluralism is the view that there are different ways of being. Historically, ways of being are aligned with the ontological categories. This paper is about to investigate why there is such a connection, and how it should be understood. Ontological pluralism suffers from an objection, according to which ontological pluralism collapses into ontological monism, i.e., there is only one way to be. Admitting to ontological categories can save ontological pluralism from this objection if ways of being ground ontological categories. (...) -/- . (shrink)

In this paper, I argue that all expressions for abstract objects are meaningless. My argument closely follows David Lewis’ argument against the intelligibility of certain theories of possible worlds, but modifies it in order to yield a general conclusion about language pertaining to abstract objects. If my Lewisian argument is sound, not only can we not know that abstract objects exist, we cannot even refer to or think about them. However, while the Lewisian argument strongly motivates nominalism, it also undermines (...) certain nominalist theories. (shrink)

A review of E.J. Lowe and Ontology, Edited By Mirosław Szatkowski. (New York, Oxford: Routledge, 2022. Pp. 326. Price £130.00.).

In this paper, I distinguish between two possible versions of Amie Thomasson’s easy ontology project that differ in virtue of positing atomic or holistic application conditions, and evaluate the strengths of a holistic version over a non-holistic version. In particular, I argue that neither of the recently identified regress or circularity problems are troublesome for the supporter of easy ontology if they adopt a holistic account of application conditions. This is not intended to be a defence of easy ontology from (...) all possible objections, but rather to compare holistic and non-holistic versions of the view. This discussion is also significant in that it serves to highlight two distinct forms of easy ontology, which, I argue, need to be distinguished when assessing the merits of the easy approach in future work.

There is no corporal philosophy at the level of other philosophical subdisciplines. A research line has begun whose ultimate goal is to determine whether a somatic philosophy can be built. From a pragmatist and biopolitical approach, the present study investigated why it has not been possible to develop grounded somatic philosophy. As an answer, the “idealist–dualist episteme” is described, which encompasses invariants in the history of idealist philosophy at the ontological, gnoseological, ethical–political, and pedagogical levels. These constants reflect somatophobia, as (...) well as an ontological and gnoseological disregard of the body, which has led to the irrelevance of the body and corporeality in philosophy until the arrival of the “bodily turn”. The critique of this prevailing idealism and dualism will enable a review of current approaches based on these positions, such as embodiment, enactivism, embodied cognition, or embodied artificial intelligence. It opens up a new philosophical line with a universalis scope that is open to the eclectic construction of a pragmatic corporal philosophy that takes into account Chinese, Japanese, or African philosophies.

The relations between ontology and information are many and fundamental, and they help us to understand the present gulf between (formal) ontology and (philosophical) Ontology: We can speak of respectively ontology-driven information and information-driven ontology as the focus on being informed vs. informed being. The question of whether these two (can) coincide is relevant to both fields, and in this article I elaborate on what needs to be addressed first of all to provide us with an answer: The form. This (...) core ontological concept rooting in Aristotelian metaphysics was central to philosophical ontology, in particular in Latin Scholasticism, when it was clearly put into relation with information as that which defines an entity. In this context, Dietrich of Freiberg synthesized this long debate in a way that matters not only to the philosophical effort of producing information-driven ontologies but also to the engineering constructs of ontology-driven information systems.

Foundational ontologies, central constructs in ontological investigations and engineering alike, are based on ontological categories. Firstly proposed by Aristotle as the very ur- elements from which the whole of reality can be derived, they are not easy to identify, let alone partition and/or hierarchize; in particular, the question of their number poses serious challenges. The late medieval philosopher Dietrich of Freiberg wrote around 1286 a tutorial that can help us today with this exceedingly difficult task. In this paper, I discuss (...) ontological categories and their importance for foundational ontologies from both the contemporary perspective and the original Aristotelian viewpoint, I provide the translation from the Latin into English of Dietrich's De origine II with an introductory elaboration, and I extract a foundational ontology–that is in fact a single-category one–from this text rooted in Dietrich's specification of types of subjecthood and his conception of intentionality as causal operation.

Genera, typically hand-in-hand with their branching species, are essential elements of vocabulary-based information constructs, in particular scientific taxonomies. Should they also feature in formal ontologies, the highest of such constructs? I argue in this article that the answer is “Yes” and that the question posed in its title also has a Yes-answer: The way medieval ontologists sliced up the world into genera does matter to formal ontology. More specifically, the way Dietrich of Freiberg, a Latin scholastic, conceived and applied strictly (...) generic criteria to slice up the world into its entities can provide some guidelines to the field of formal ontology with respect to not only its contents, but also its scope. In particular, Dietrich's information criterion plays here a central role. (shrink)

Many powers-realists assume that the powers of objects are identical with the dispositions of objects and, hence, that ‘power’ and ‘disposition’ are interchangeable. In this article, I aim to disentangle dispositions from powers with the goal of getting a better sense of how powers and dispositions relate to one another. I present and defend a modest realism about dispositions built upon a standard strong realism about powers. I argue that each correct disposition-ascription we can make of an object is made (...) true by the manifestations towards which a given power or collection of powers of the object is directed.RésuméDe nombreux réalistes des pouvoirs supposent que les pouvoirs des objets sont identiques aux dispositions des objets et, par conséquent, que le « pouvoir » et la « disposition » sont interchangeables. Dans cet article, j'ai pour objectif de démêler les dispositions des pouvoirs dans le but d'avoir une meilleure idée de la façon dont les pouvoirs et les dispositions se rapportent les uns aux autres. Je présente et défends un réalisme des dispositions modeste fondées sur un réalisme des pouvoirs standard fort. Je soutiens que chaque disposition-ascription correcte que nous pouvons faire d'un objet est rendue vraie par les manifestations vers lesquelles un pouvoir donné ou une collection de pouvoirs de l'objet est dirigé.

In this very issue, Augusto (2022) formulates two requirements upon which to evaluate the adequacy of a foundational ontology. Specifically, the ontological categories: (i) should be understood as the most general kinds of things and (ii) are organized in a non-overlapping finite hierarchy. On the basis of such constraints, he claims that most existing foundational ontologies engineered in the context of Applied Ontology, including the UFO-B ontology, are inadequate. In this article, first we show that his objection against UFO-B can (...) be dissipated by pointing to a trivial terminological confusion. We then argue that his two constraints are not plausible. Then, we show that the disagreement between our point of view and Augusto’s framework is not restricted to those two constraints but extends over the notion of conceptualization of reality. (shrink)

In this paper, I seek to explain Suhrawardī’s method of writing his allegories – how he draws upon his philosophical principles to construct forms and plots of his stories. To do so, I begin by delineating two key doctrines of his Illuminationist (Ishrāqī) ontology: the world of Forms (‘ālam al-muthul) and the discontinuous imaginal world (‘ālam al-mithāl al-munfaṣil). I provide an account of the history of these two doctrines and the nature of these two worlds, and then consider some of (...) their functions for, and effects on, Suhrawardī’s explanations and analyses. I will then deal with Suhrawardī’s allegories, pinpointing particular effects of the belief in the world of Forms and the imaginal world on his symbolisms and allegories. Distinguishing three main spiritual-mystical notions in Suhrawardī’s allegories, I elaborate upon the role of the above two doctrines in his construction of characters and fictional events, whereby I demystify certain symbols in these stories. I conclude that there is a close tie between Suhrawardī’s allegories and his philosophical doctrines. Thus, his spiritual doctrines are presented in a symbolic form in certain allegorical characters and adventures. The deployment of characteristics of the world of Forms and the imaginal world plays a central role here. (shrink)

This is a commentary on the article by Augusto (2022; this issue) on categories and foundation ontology (FO). We agree that the notion of categories of kinds of elements to devise a FO deserves more attention than it has received to date. From a practical point of view sensu developing domain ontologies, however, it probably does not matter much as long as a FO is used and that that one was understood.

In this paper, I discuss how to distinguish between ontological categories and ordinary categories. Using an argument against van Inwagen’s proposed account of what makes a category ontological as a springboard, I argue that if ontological categories are modally robust, then ontological categories need to be understood hyperintensionally. This conclusion opens up a wide range of new ways to define ‘ontological category’, and I close by briefly outlining one such way in order to illustrate the advantages of embracing hyperintensionality in (...) this debate.

The argument by which the Eleatic Stranger differentiates the kinds being and different (255c9-e2) is one of the most controversial in Plato’s Sophist. In it the Stranger introduces the vexed distinction between beings that are auta kath’ hauta, ‘themselves according to themselves’, and those that are pros alla, ‘relative to others’ (255c13-14). Although commentators have developed many interpretations of the argument, there is a key yet hitherto unrecognized ambiguity in the syntax of the counterfactual conditional at 255d4-6, concerning whether the (...) adjunct comparative clause, hōsper to on, should be adjoined to the protasis or apodosis. Editors from Heindorf to Robinson adjoin hōsper to on to the protasis. I argue this is mistaken. Adjoining hōsper to on to the apodosis instead allows for a more straightforward interpretation of the argument and offers a resolution to the controversies surrounding the ‘according to themselves’ / ‘relative to others’ distinction.

Ontologies are some of the most central constructs in today's large plethora of knowledge technologies, namely in the context of the semantic web. As their coinage indicates, they are direct heirs to the ontological investigations in the long Western philosophical tradition, but it is not easy to make bridges between them. Contemporary ontological commitments often take causality as a central aspect for the ur-segregation of entities, especially in scientific upper ontologies; theories of causality and philosophical ontological investigations often go hand-in-hand, (...) and were essentially inseparable in medieval thought. This constitutes the foundation for a bridge, and this article analyzes the causality-based ontology of the late medieval philosopher Dietrich of Freiberg from the viewpoint of today's upper-ontology engineering. In this bridging attempt, it offers a translation into English of the first part of Dietrich's De origine (abbreviated title) that is a compromise between traditional scholarly translations of medieval Latin philosophical texts and contemporary ontology.

_Nicolai Hartmann and Alexius Meinong on Apriority and Causality. Notes on the Correspondence_ The article offers a critical reading of the nine letters composing the correspondence exchanged by Alexius Meinong (1853-1920) and Nicolai Hartmann (1882-1950) in 1915 and 1918-1920. The author explores the main contents of the correspondence, through a chronological-thematic analysis. The letters of 1915 are eminently dedicated to a discussion of the gnoseology-ontology relationship. Here, the author focuses (1.1) on the relationship between reality and knowledge and (1.2) on (...) that between a priori and cognitive principles. The analysis (2) of the 1918-1920 correspondence concludes the article, engaging in the theme of the law of causality. Different in the philosophical background and argumentative style, the late Meinong and the young Hartmann find a field of dialogue that appears not lacking in consequences on the philosophical evolution of the latter.

It has been a common assumption that words are substances that instantiate or have properties. In this paper, I question the assumption that our ontology of words requires posting substances by outlining a bundle theory of words, wherein words are bundles of various sorts of properties (such as semantic, phonetic, orthographic, and grammatical properties). I argue that this view can better account for certain phenomena than substance theories, is ontologically more parsimonious, and coheres with claims in linguistics.

In this article I discuss several apparent counterexamples to the asymmetry of ontological dependence. These counterexamples were introduced in discussions about grounding, but they can affect every theory of ontological dependence. I show that, if one adopts metaontological pluralism (i.e., the view according to which there are many dependence relations), one has some advantages when it comes to defending the asymmetry of dependence. In Section 1, I introduce metaontological pluralism and my own version of it, which is based on Respect-of-Dependence (...) Relations (RD-Relations). I then single out five strategies to deal with apparent cases of symmetric dependence and show that only two of them are available to metaontological pluralists. In Sections 2, 3, and 4 I deal with cases of symmetric dependence by adopting these strategies. Finally, in Section 5, I anticipate and reply to three objections against my account. (shrink)

Universals appear to be as central in today's computational-based ontology as they were in medieval ontological investigations. As the author of a recent work on the history of universals (Pinzani, 2018), I was asked for a commentary on Augusto’s article “Bridging Mainstream and Formal Ontology” (Augusto, 2021), which aims at showing that medieval ontological investigations can be relevant for contemporary ontology engineering. In this commentary, I begin by saying something about my way of reading 12th-century logical literature and then offer (...) some modest considerations on the general theme addressed in Augusto's article.

Pantheists are often accused of lacking a sufficient account of the unity of the cosmos and its supposed priority over its many parts. I argue that complex theists, those who think that God has ontologically distinct parts or attributes, face the same problems. Current proposals for the metaphysics of complex theism do not offer any greater unity or ontological independence than pantheism, since they are modeled on priority monism. I then discuss whether the formal distinction of John Duns Scotus offers (...) a way forward for complex theists. I show that only those classical theists who affirm divine simplicity are better off with respect to aseity and unity than pantheists. Only proponents of divine simplicity can fairly claim to have found a fully independent ultimate being. (shrink)

In this paper we introduce some logical and philosophical refinements to OntoClean, first by developing some formal constraints on identity criteria, secondly by specifying a kind of identity criteria, two level identity criteria, whose role is to explain an identity among some entities referring to some other, more basic, entities. Using such refinement we add a formal constraint to the stock of OntoClean meta-constraints (OC+). We, then, observe that two level identity criteria have an intuitive reading in terms of dependence (...) of a kind of entities on some other entities, possibly specified in terms of a grounding relation. Are identity criteria grounding principles? In the second part of the paper we discuss this option. (shrink)

The thesis of this paper is that our understanding of life, as reflected in the biological and medical sciences but also in our everyday transactions, has been hampered by an inappropriate metaphysics. The metaphysics that has dominated Western philosophy, and that currently shapes most understanding of life and the life sciences, sees the world as composed of things and their properties. While these things appear to undergo all kinds of changes, it has often been supposed that this amounts to no (...) more than a change in the spatial relations of their unchanging parts. From antiquity, however, there has been a rival to this view, the process ontology, associated in antiquity with the fragmentary surviving writings of Heraclitus. In the last century it has been especially associated with the work of the British metaphysician and logician, Alfred North Whitehead. For process ontology, what most fundamentally exists is change, or process. What we are tempted to think of as constant things are in reality merely temporary stabilities in this constant flux of change, eddies in the flux of process. My main claim in this paper will be that a metaphysics of this latter kind is the only kind adequate to making sense of the living world. After explaining in more detail, the differences between these ontological views, I shall illustrate the advantages of a process ontology with reference to the category of organism. Finally I shall explore some further implications of a process ontology for biology and for philosophy. (shrink)

The aim of this thesis is to propose a deflationary approach towards the ontological analysis of physical theories. Such an approach sustains that the development of ontologies for physical theories must be neutral relatively to the debate between realists and anti-realists in philosophy of physics. Mainly, our attention will be oriented towards what we called "quantum domain", which includes the non-relativistic Quantum Mechanics and variants of the Quantum Field Theory. This meta-ontological approach consists in an attempt to provide a methodology (...) for the development of specific ontologies for physical theories. With this aim we suggest the separation between physical phenomena and physical theories on one side, and physical theories and ontologies on the other side. This separation intends to endorse the idea that physical theories can provide all the informative contents required for the development of the ontologies associated with them. The result is a defense of the idea that physical theories can positively contribute for the constitution of the ontologies in physics. Additionally, we present a critical analysis of four different ontological approaches to QM and QFT. Each one of these interpretations deals with a different ontological category (tropes, events and processes). At the end of the thesis we will analyze the concepts of interaction and commutation in QFT in order to exemplify the main lines of the deflationary approach suggested here. (shrink)

Here, I lay the foundations of a high-level ontology of particulars whose structuring principles differ radically from the 'continuant' vs. 'occurrent' distinction traditionally adopted in applied ontology. These principles are derived from a new analysis of the ontology of “occurring” or “happening” entities. Firstly, my analysis integrates recent work on the ontology of processes, which brings them closer to objects in their mode of existence and persistence by assimilating them to continuant particulars. Secondly, my analysis distinguishes clearly between processes and (...) events, in order to make the latter abstract objects of thought (alongside propositions). Lastly, I open my ontological inventory to properties and facts, the existence of which is commonly admitted. By giving specific roles to these primitives, the framework allows one to account for static and dynamic aspects of the physical world and for the way that subjects conceive its history: facts account for the life of substances (physical objects and processes), whereas events enable cognitive subjects to account for the life story of substances.

In this thesis I argue against unrestricted mereological hybridism, the view that there are absolutely no constraints on wholes having parts from many different logical or ontological categories, an exemplar of which I take to be ‘mixed fusions’. These are composite entities which have parts from at least two different categories – the membered (as in classes) and the non-membered (as in individuals). As a result, mixed fusions can also be understood to represent a variety of cross-category summation such as (...) the abstract with the concrete, the physical with the non-physical, and the possible with the impossible, just to name a few. -/- Proposed by David Lewis (1991) alongside his defence of classical mereology (the major theory of parthood which permits such transcategorial composites through its principle of unrestricted composition) it is my contention that mixed fusions are an under-examined consequence of indiscriminate mereological fusion which harbour a multitude of complications. In my attempt to discern their substantive character, throughout this thesis I make a case study of mixed fusions and uncover several problematic consequences which I think follow from their most plausible assessment. -/- These include: (1) that mixed fusions’ probable membership relations may lead to dubious foundational loops in the mereological Universe, or (2) otherwise that mixed fusions oblige an implausible ontological priority of the mereological Universe as a whole; (3) that mixed fusions contradict the reductive account of set theory they are proposed within, by plausibly being seen to have the same members as their class parts, and (4) that mixed fusions therefore confound a mereological thesis of Composition as Identity, which some (including Lewis) use to support classical mereology – a consequence which is potentially self-defeating; (5) that mixed fusions as sums of abstract and concrete entities both subvert Lewis’s (1986) system of modal realism, while (6) also undermining less expansive theories of possible worlds; and finally, (7) that even where some of the foregoing is resisted, it remains implausible that mixed fusions are ontologically innocent, because their supposed distinction from their parts in this case ensures that they need to be counted as additional entities in one’s ontology. -/- To be clear, I do not advance a theory of mereological hybrid nihilism in the sense of denying all cases of transcategorial composition. (I only cover a few select instances of mereological hybridism via mixed fusions after all.) Rather, I deny that mereological hybridism is plausible in full generality, by demonstrating that any cases of it are at least limited by the constraints that I identify. This in turn vindicates a call for a restriction on parthood theories and composition principles which allow certain types of categorially mixed entities – including restricting classical mereology with its principle of unrestricted composition. -/- Although theories of parthood like the standard classical mereology are not ordinarily developed for the sake of mereological hybrids like mixed fusions, these and other transcategorial composites are still among the logical consequences of such parthood systems operating with sufficient generality. The significance of my thesis, then, comes from showcasing how some of these kinds of entities do not conform to the systems in which they are included as required, and hence I argue for the rejection of unrestricted mereological hybridism as well as any mereological principles which support it.

Ethnobotanical research provides ample justification for comparing diverse biological nomenclatures and exploring ways that retain alternative naming practices. However, how (and whether) comparison of nomenclatures is possible remains a subject of discussion. The comparison of diverse nomenclatural practices introduces a suite of epistemic and ontological difficulties and considerations. Different nomenclatures may depend on whether the communities using them rely on formalized naming conventions; cultural or spiritual valuations; or worldviews. Because of this, some argue that the different naming practices may not (...) be comparable if the ontological commitments employed differ. Comparisons between different nomenclatures cannot assume that either the naming practices or the object to which these names are intended to apply identifies some universally agreed upon object of interest. Investigating this suite of philosophical problems, I explore the role grey nomenclatures play in classification. ‘Grey nomenclatures’ are defined as those that employ names that are either intentionally or accidentally non-Linnaean. The classification of the lichen thallus (a symbiont) has been classified outside the Linnaean system by botanists relying on the International Code of Nomenclature for algae, fungi, and plants (ICN). But, I argue, the use of grey names is not isolated and does not occur exclusively within institutionalized naming practices. I suggest, ‘grey names’ also aptly describe nomenclatures employed by indigenous communities such as the Samí of Northern Finmark, the Sherpa of Nepal, and the Okanagan First Nations. I pay particular attention to how naming practices are employed in these communities; what ontological commitments they hold; for what purposes are these names used; and what anchors the community’s nomenclatural practices. Exploring the history of lichen naming and early ethnolichenological research, I then investigate the stakes that must be considered for any attempt to preserve, retain, integrate, or compare the knowledge contained in both academically formalized grey names and indigenous nomenclatures in a way that preserves their source-specific informational content.

Natural languages generally distinguishes among different existence predicates for different types of entities, such as English 'exist', 'occur', and 'obtain'. The paper gives an in-depth discussion and analysis of a range of existence predicates in natural language within the general project of descriptive metaphysics, or more specifically ‘natural language ontology’.

Nominalizations of modal predicates have received little, if any, attention in the semantic or philosophical literature. This paper will argue that nominalizations of modal predicates require recognizing a novel ontological category of modal objects and it will outline a new semantics of modals based on modal objects.

"Ontology" focuses on three ways ground and ontology are said to relate. One way involves ground's ability to provide a safe and sane way of admitting certain kinds of things in our theories. Another way involves ground's ability to show how we should measure ontological simplicity. And a third way involves ground's ability to restrict what things or kinds of things can depend on other things or kinds.
