Although the question of relationship between basic concepts of traditional ontology and central concepts of fundamental ontology is not a topic which is systematically dealt with in Being and Time, it is obvious that some of the theses which are crucial not only for Heidegger's interpretation of philosophical tradition, but also for the whole project of fundamental ontology, concern this 'conceptual scheme'. In fact, the backbone of Heidegger's critical confrontation with dominant philosophical conceptions is the question (...) of relationship between the concept of 'substance' and the concept of 'Being', i.e. the discussion of philosophical doctrines in which 'Being' is reduced to 'substance'. Besides this context, which concerns the ontological problematics in the strict sense, it is possible to show that the refutation of the basic categories of traditional ontology is an issue which has a decisive role in more concrete phases of the realization of the project of fundamental ontology. This is especially confirmed in Heidegger's discussion of the concept of 'Being-There'. The interpretation of Heidegger's treatment of the relationship between the concepts of 'Being-there', 'existence' and 'existentials' on the one hand, and the concepts of 'substance', 'essence' and 'categories' on the other, shows that one of Heidegger's basic theses is that a transformation of concepts of traditional ontology is necessary for an appropriate understanding of human being. Iako pitanje odnosa izmedju temeljnih pojmova tradicionalne ontologije i centralnih pojmova fundamentalne ontologije nije tema koja je sistematicno obradjena u Bitku i vremenu, evidentno je da se neke od teza koje su kljucne ne samo za Hajdegerov odnos prema filozofskoj tradiciji, vec i za celokupan projekat fundamentalne ontologije, ticu suceljavanja pomenutih 'pojmovnih aparatura'. Naime, okosnicu u Hajdegerovom distanciranju od nasledjenih filozofskih koncepcija cini upravo propitivanje odnosa izmedju pojma 'supstancija' i pojma 'bitak', odnosno, osporavanje filozofskih ucenja u kojima se pojam 'bitak' svodi na pojam 'supstancija'. 'Destrukcija' tradicionalne ontologije, kao interpretativni model kojim Hajdeger pristupa filozofskoj povesnoj predaji, postavljena je kao problematizovanje nasledjenog poimanja bitka kao 'supstancije', nasuprot kojem se razvija fundamentalnoontolosko razmatranje 'problema bitka'. Pored naznacenog konteksta, u kome je rec o ontoloskoj problematici u uzem smislu, moguce je pokazati da je osporavanje temeljnih kategorija tradicionalne ontologije tema koja ima odlucujucu ulogu i u konkretnijim etapama realizacije projekta fundamentalne ontologije. Prethodno se posebno potvrdjuje u Hajdegerovoj tematizaciji pojma 'tubitak'. Sagledavanjem Hajdegerovih izvodjenja u kojima se razmatra veza izmedju pojmova 'tubitak', 'egzistencija' i 'egzistencijalije', sa jedne strane, i pojmova 'supstancija', 'sustina' i 'kategorije', sa druge, i procenjuje merodavnost navedenih pojmova tradicionalne ontologije u izlaganju ljudskog bitka, dolazi se do uvida da Hajdeger polazi od teze prema kojoj je u svrhu dosezanja izvornog razumevanja coveka nuzno izvrsiti prevrat u pojmovnosti tradicionalne ontologije.

Contains a brief survey of the first Critique’s Transcendental Dialectic, but it is primarily devoted to a treatment of Kant’s changing views on the fundamental question of how to arrive at a theoretical account of the unity of the world that overcomes the shortcomings of occasionalism, theories of pre-established harmony, and naïve versions of the doctrine of ‘physical influx’. It stresses that although it is very difficult to determine exactly how Kant comes to a distinctive and stable position on this (...) question, the topic is clearly of fundamental importance in all stages of his work, and throughout all of them he favours the affirmation of real interaction between finite substances. Draws on ideas and materials from lectures by Kant, and it also relies heavily on several newly found sets of notes from Kant’s lectures on metaphysics. (shrink)

The analytic movement advertised its 'linguistic turn' as a radical break from the two-thousand-year-old substance tradition. But this is an illusion. On the fundamental level of ontology, there is enough reformulation and presupposition of traditional 'no entity without identity' themes to analogize Frege, Russell, Wittgenstein, and Quine to Aristotle as paradigmatic of modified realism. Thus the pace of ontology is glacial. Frege and Russell, not Wittgenstein and Quine, emerge as the true analytic progenitors of 'no entity without (...) identity,' offering between them at least twenty-nine private language arguments and sixty-four 'no entity without identity' theories.

Analytic theologians seem to unreservedly prioritize a realist view in the way they approach theological dogmas. I have previously argued that this particular type of realist methodological approach is inconsistent with the Islamic tradition. I demonstrated that this inconsistency lies between two primary theses which constitute realism and an absolutely transcendent and ineffable God of the Islamic tradition. I had established how each of these theses proved responsible, in different ways, for divesting the Islamic God of His absolute transcendence. In (...) this paper I determine why this is the case. I primarily seek to explicate the underlying reason for why metaphysical (theological) realism proves to be responsible for stripping the Islamic God of His absolute transcendence. This would involve being able to stipulate, somewhat accurately, the precise source of the accentuated inconsistency between metaphysical (theological) realism and the Islamic understanding of an absolutely transcendent and ineffable God. The exact source of this inconsistency, I shall argue, is grounded in Quine’s ontological theses, which underlie much of what metaphysical realism imports into the domain of analytic theology.

Against the background that the top-level semantic framework of Chinese traditional culture is not comprehensive and unified, this study aims to preserve and disseminate cultural heritage information about Chinese traditional culture through the development of a domain ontology which is constructed from ancient books. A combination of top-down and bottom-up approaches was used to construct the ontology for Chinese traditional culture. An investigation of historians’ needs, and LDA topic clustering model were conducted, understanding the specific (...) needs of historians, collecting the topic, concepts and relationships. CIDOC CRM was reused to construct the basic framework of CTCO. Ontology structure and function were adopted to evaluate the effectiveness of CTCO. Evaluation results show that the ontology meets all the quality criteria of OntoMetrics, and the experts agreed on content representation. CTCO contributes to the organization of traditional Chinese culture and the construction of related databases. The study also forms a common path and puts forward proposals for the construction of domain ontology, which has great social relevance. (shrink)

I shall explain the notions of propositions and states of affairs as they are understood in the current ontological debate and I shall briefly relate them to similar notions in Aristotle and some Medieval authors. In contrast with the point of view of some philosophers who identify propositions and states of affairs, I shall argue that they need to be sharply distinguished. I shall then move on to a problem for propositions and, above all, states of affairs, known as Bradley’s (...) regress, and hint at discussions of this or analogous puzzles in the philosophical tradition before Bradley. Finally, I shall present my own approach to this issue, Fact Infinitism, focusing on why it would have been hardly acceptable before ontology came to have the Cantorian conception of the infinite at its disposal.

One of the aims of Gadamer’s hermeneutic ontology is the definition of the specific character of the human sciences. Gadamer maintains that their method is based upon the acknowledgement of the authority of tradition. Hence the main problem that faces his theory is the question of what makes the investigation in the humanities scientific and innovative. In my paper I try to reconstruct Gadamer’s solution of this problem. I consider his notion of tradition and its role in the definition (...) of understanding as a cognition of truth. For Gadamer tradition is a precondition both of all possibility of understanding and of the historicity of the hermeneutic happening. This conception permits to define how the human sciences grasp the reality and what is studied by them. (shrink)

The philosophical study of what exists and what it means for something to exist is one of the core concerns of metaphysics. This introduction to ontology provides readers with a comprehensive account of the central ideas of the subject of being. This book is divided into two parts. The first part explores questions of pure philosophical ontology: what is meant by the concept of being, why there exists something rather than nothing, and why there is only one logically (...) contingent actual world. Dale Jacquette shows how logic provides the only possible answers to these fundamental problems. The second part of the book examines issues of applied scientific ontology. Jacquette offers a critical survey of some of the most influential traditional ontologies, such as the distinction between appearance and reality, and the categories of substance and transcendence. The ontology of physical entities - space, time, matter and causation - is examined as well as the ontology of abstract entities such as sets, numbers, properties, relations and propositions. The special problems posed by the subjectivity of mind and of postulating a god are also explored in detail. The final chapter examines the ontology of culture, language and art. (shrink)

This essay discusses how ontological commitments within modern Western culture are no less problematic than those within traditional African cultures. Each posits unobservable entities to explain the experiential world, and neither has ready access to those posits held as grounding or as otherwise determining what is experienced. It looks at the conceptions of persons in Western and African traditions and suggests that each tradition can learn from the other.

It is no exaggeration to say that of the early 20th century German philosophers who claimed to establish a new ontology, former neo-Kantian turned realist Nicolai Hartmann is the only one to have actually followed through. "Ontology: Laying the Foundations" deals with "what is insofar as it is," and its four parts tackle traditional ontological assumptions and prejudices and traditional categories such as substance, thing, individual, whole, object, and phenomenon; a novel redefinition of existence and essence (...) in terms of the ontological factors Dasein and Sosein and their interrelations; an analysis of modes of "givenness" and the ontological embeddedness of cognition in affective transcendent acts; and a discussion of the status of ideal being, including mathematical being, phenomenological essences, logical laws, values, and the interconnections between the ideal and real spheres. Hartmann’s work offers rich resources for those interested in overcoming the human-centeredness of much 20th century philosophy.

Dustin McWherter defends the possibility of critical ontology by pitting Roy Bhaskar's attempt to rehabilitate ontology in the philosophy of science against Kant's attempt to replace traditional ontology with an account of cognitive experience.

Ontology has been proposed as a solution to the 'Tower of Babel' problem that threatens the semantic interoperability of information systems constructed independently for the same domain. In information systems research and applications, ontologies are often implemented by formalizing the meanings of words from natural languages. However, words in different natural languages sometimes subdivide the same domain of reality in terms of different conceptual categories. If the words and their associated concepts in two natural languages, or even in two (...) terminological traditions within the same language, do not have common referents in the real world, an ontology based on word meanings will inherit the 'Tower of Babel' problem from the languages involved, rather than solve it. In this paper we present evidence from a preliminary comparison of landscape terms in English with those in the Yindjibarndi language of northwestern Australia demonstrating that this problem is not just hypothetical. Some possible solutions are suggested. (shrink)

How does the critical Kant view ontology? There is no shared scholarly answer to this question. Norbert Hinske sees in the Critique of Pure Reason a “farewell to ontology,” albeit one that took Kant long to bid (Hinske 2009). Karl Ameriks has found evidence in Kant’s metaphysics lectures from the critical period that he “was unwilling to break away fully from traditional ontology” (Ameriks 1992: 272). Gualtiero Lorini argues that a decisive break with the tradition of (...) ontology is essential to Kant’s critical reform of metaphysics, as is reflected in his shift from “ontology” to “transcendental philosophy,” two notions that Lorini takes to be related by mere “analogy” (Lorini 2015). I agree with Lorini that a thorough reform of ontology is a pivotal part of Kant’s critical plan for metaphysics and that ontology somehow “survives within the critical philosophy” (Lorini 2015: 76). To make this case, however, I deem it important to identify “ontology” and “transcendental philosophy” in the sense of extensional equivalence. While we can detect this identification in Kant’s writings, only from his metaphysics lectures can we get a full sense of its historical and philosophical significance. In this chapter I focus on how it represents a definitive turn from as well as notable continuity with traditional treatments of ontology, particularly the Wolffian one. (shrink)

Semyon Frank opposed the Neo-Kantian School and admitted the real existence of the objects of cognition. He treated ontologism as essential to the entire movement of Russian religious philosophy. For Frank, one can only know about something thanks to the absolute, which exists prior to the knowing subject. Ontologism, affirming the priority of being over cognition, has a great significance not only for metaphysics and epistemology, but also for the philosophy of religion. In particular, Frank taught that the most privileged (...) mode of cognition of God is intuition, an immediate experience of God or faith. Intuition is at the heart of the ontological proof, which can be found in St. Anselm, Descartes, and Frank himself. Frank dedicated a number of articles to this topic: “K istorii ontologicheskogo dokazatel’stva”, “Ontologicheskoe dokazatel’stvo bytiya Boga”, as well as texts recently discovered at the Bakhmeteff Archive, including “Dokazatel’stvo bytiya Boga”. In this way, Russian ontologism leads to a new interpretation of the traditional ontological proof, one which acknowledges the existence of God, not on the basis of arguments resting on His definition, but on the basis of the intuitive recognition of His being.

Ontology has been traditionally guided by sophia, a form of knowledge directed toward that which is eternal, permanent, necessary. This tradition finds an important early expression in the philosophical ontology of Aristotle. Yet in the Nicomachean Ethics, Aristotle's intense concern to do justice to the world of finite contingency leads him to develop a mode of knowledge, phronsis, that implicitly challenges the hegemony of sophia and the economy of values on which it depends. Following in the tradition of (...) the early Heidegger's recognition of the ontological significance of Aristotle's Ethics and of Gadamer's appropriation of phronsis for hermeneutics, this article argues that an ontology guided by phronsis is preferable to one governed by sophia. Specifically, it suggests that by taking sophia as its paradigm, traditional philosophical ontology has historically been determined by a kind of knowledge that is incapable of critically considering the concrete historico-ethico-political conditions of its own deployment. This critique of sophia is accomplished by uncovering the economy of values that led Aristotle to privilege sophia over phronsis. It is intended to open up the possibility of developing an ontology of finite contingency based on phronsis. Such an ontology, because it is guided by and must remain responsible to the concrete individual with which it is engaged, would be ethical at its very core. (shrink)

This is a critical review of a book that defends two basic theses about analytic philosophy--that the 'no entity without identity' ontology is basic to the four great analytic philosophers and that they were 'modified realists.' This review calls into question both of these claims. The ontological views of Frege, Russell, Quine, Wittgenstein and others are discussed as well other central issues in analytic philosophy.

In this paper, I will attempt to formulate some observations about the limits of a traditional ontology that is in its essence a judicative one. The main goal is to explore the possibility of constructing a pre-judicative ontology; in other words, to describe the cognitive and affective elements that are “under” the main ontological judgments, related naturally to being. The arguments in favor of a pre-judicative ontology offer a new perspective on judicative ontology itself. This (...) pre-judicative ontology is nevertheless a kind of judicative ontology that covers a nonspecific realm of values. The paper has three parts: 1) a description of the main characteristics of traditional ontology from a judicative perspective; 2) the formulation of some logical conditions of possibility for a pre-judicative ontology; and 3) the outline of a pre-judicative ontology as an ontology of values.

Traditional Christianity holds that God is a singular way, not dependent on the conceptual machinations of humans. I argue that God can be plural ways, different in different human conceptual schemes, all the while holding to traditional Christianity.

This provocative book attempts to resolve traditional problems of identity over time. It seeks to answer such questions as 'How is it that an object can survive change?' and 'How much change can an object undergo without being destroyed'? To answer these questions Professor Heller presents a theory about the nature of physical objects and about the relationship between our language and the physical world. According to his theory, the only actually existing physical entities are what the author calls (...) 'hunks', four-dimensional objects extending across time and space. This is a major contribution to ontological debate and will be essential reading for all philosophers concerned with metaphysics. (shrink)

A relation between Sartre's phenomenological ontology and the German idealist tradition is frequently assumed in the secondary literature on Sartre. The literature that confronts this question usually adopts a piecemeal approach, treating individual philosophers, usually Hegel, in the mode of comparison and contrast. This approach, though fruitful in a limited fashion, obscures the broader question of Sartre's relation to German idealism as a whole. This study attempts to place Sartre in the context of an internal debate within idealist thought, (...) as one player in an ongoing dialogue. Its task is the establishment of Sartre's phenomenological ontology in Being and Nothingness as essentially idealist in both form and content. ;This work proceeds primarily through interaction with primary texts, beginning with Sartre's early piece, Imagination: A Psychological Critique. From this book we abstract a critical methodology that we discover is ubiquitous in Sartre's early works. In particular, we examine the application of it to the idealists in Being and Nothingness, learning both its failures in terms of representational accuracy and its successes in advancing Sartre's argument. These discoveries lead us to explore the distinction Sartre draws between metaphysics and ontology, which is critical to understanding the nature of Sartre's entire project. Having clarified this distinction, we return our attention to the critical methodology, which displays both an intimate connection to, and important distinctions from, Hegel's dialectical logic. Notably, if Sartre's position is best understood as an ongoing 'moment' in the developing narrative of idealist thought, we conclude that the profound nature of Sartre's relation to Hegel is that of opposition. Sartre's opposition to Hegel in turn may be seen as analogous to the Kantian project of establishing intellectual space for ethics in the face of scientific rationalism. Sartre, I argue, reinstitutes Kant's "Copernican revolution" on the ontological level as a response to the necessitarianism issuing from Hegel's dialectical logic. This response intends to place the realm of ethics forever beyond the possibility of doubt by forbidding metaphysical speculation any functional relevance to human existence. To live as anything other than free moral agents is to live in bad faith. (shrink)

A close examination of the literature on ontology may strike one with roughly two distinct senses of this word. According to the first of them, which we shall call traditional ontology , ontology is characterized as the a priori study of various “ontological categories”. In a second sense, which may be called naturalized ontology , ontology relies on our best scientific theories and from them it tries to derive the ultimate furniture of the world. (...) From a methodological point of view these two senses of ontology are very far away. Here, we discuss a possible relationship between these senses and argue that they may be made compatible and complement each other. We also examine how logic, understood as a linguistic device dealing with the conceptual framework of a theory and its basic inference patterns must be taken into account in this kind of study. The idea guiding our proposal may be put as follows: naturalized ontology checks for the applicability of the ontological categories proposed by traditional ontology and give substantial feedback for it. The adequate expression of some of the resulting ontological frameworks may require a different logic. We conclude with a discussion of the case of orthodox quantum mechanics, arguing that this theory exemplifies the kind of relationship between the two senses of ontology. We also argue that the view proposed here may throw some light in ontological questions concerning this theory. (shrink)

In this paper I elicit a prediction from structural realism and compare it, not to a historical case, but to a contemporary scientific theory. If structural realism is correct, then we should expect physics to develop theories that fail to provide an ontology of the sort sought by traditional realists. If structure alone is responsible for instrumental success, we should expect surplus ontology to be eliminated. Quantum field theory (QFT) provides the framework for some of the best (...) confirmed theories in science, but debates over its ontology are vexed. Rather than taking a stand on these matters, the structural realist can embrace QFT as an example of just the kind of theory SR should lead us to expect. Yet, it is not clear that QFT meets the structuralist's positive expectation by providing a structure for the world. In particular, the problem of unitarily inequivalent representations threatens to undermine the possibility of QFT providing a unique structure for the world. In response to this problem, I suggest that the structuralist should endorse pluralism about structure. (shrink)

This paper describes the implications of the transition from Ontology conceived as fundamental metaphysical logos to ontologies construed as postmodern historical applications of this, and then, finally, to Trans-Ontology as the ultimate, futuristic innovation of Transhumanism. If modernity counts as the key shift that has occurred in our living and understanding of the world since the dawn of history, postmodernism seems to be the record of a transition from the absolute Grand Narratives of modernity to a scenario consisting (...) of polycentric, equally justified narratives. Thus, the historical failure of the old Ontology, in the form of monarchy, absolutism, monotheistic religions, Eurocentrism, and nationalism, entails the plurality of approaches and diversity of flexible transformations of ontologies. Yet such a purportedly liberating evolution is encountered en route to the likewise postmodern trans-humanist impulse that aims at a complete transformation of the traditional human essence by means of a theurgist, miraculous, Trans-Theological technology. The latter’s goal is to normalize the arrival of a paradoxically innovative universe, where transhuman beings will rebuild the world, and re-essentialize it. Ultimately, this universal integralism will be based on an ever-growing ludic character, coupled with a mathematically scheduled playfulness, aiming at a transformed, fully integrated and manageable entity.

Ontology tends to be held in deep suspicion by many currently engaged in the study of technology. The aim of this paper is to suggest an ontology of technology that will be both acceptable to ontology’s critics and useful for those engaged with technology. By drawing upon recent developments in social ontology and extending these into the technological realm it is possible to sustain a conception of technology that is not only irreducibly social but able to (...) give due weight to those features that distinguish technical objects from other artefacts. These distinctions, however, require talk of different kinds of causal powers and different types of activity aimed at harnessing such powers. Such discussions are largely absent in recent technological debates, but turn out to be significant both for ongoing technology research and for the recasting of some more traditional debates within the philosophy of technology.

In the era of “big data,” science is increasingly information driven, and the potential for computers to store, manage, and integrate massive amounts of data has given rise to such new disciplinary fields as biomedical informatics. Applied ontology offers a strategy for the organization of scientific information in computer-tractable form, drawing on concepts not only from computer and information science but also from linguistics, logic, and philosophy. This book provides an introduction to the field of applied ontology that (...) is of particular relevance to biomedicine, covering theoretical components of ontologies, best practices for ontology design, and examples of biomedical ontologies in use. After defining an ontology as a representation of the types of entities in a given domain, the book distinguishes between different kinds of ontologies and taxonomies, and shows how applied ontology draws on more traditional ideas from metaphysics. It presents the core features of the Basic Formal Ontology (BFO), now used by over one hundred ontology projects around the world, and offers examples of domain ontologies that utilize BFO. The book also describes Web Ontology Language (OWL), a common framework for Semantic Web technologies. Throughout, the book provides concrete recommendations for the design and construction of domain ontologies. (shrink)

The modal properties of the principle of the causal closure of the physical have traditionally been said to prevent anything outside the physical world from affecting the physical universe and vice versa. This idea has been shown to be relative to the definition of the principle. A traditional definition prevents the one universe from affecting any other universe, but with a modified definition, e.g., the causal closure of the physical can be consistent with the possibility of one universe affecting (...) the other universe. Gamper proved this modal property by implementing interfaces between universes. Interfaces are thus possible, but are they realistic? To answer this question, I propose a two-step process where the second step is scientific research. The first step, however, is to fill the gap between the principles or basic assumptions and science with a consistent theoretical framework that accommodates the modal properties of an ontology that matches the basic assumptions.

We classify two of Bertrand Russell's theories of events within the point-free ontology. The first of such approaches was presented informally by Russell in ‘The World of Physics and the World of Sense’ (Lecture IV in Our Knowledge of the External World of 1914). Based on this theory, Russell sketched ways to construct instants as collections of events. This paper formalizes Russell's approach from 1914. We will also show that in such a reconstructed theory, we obtain all axioms of (...) Russell's second theory from 1936 and all axioms of Thomason's theory of events from 1989. Russell's work certainly influenced the works of Stanisław Leśniewski, his student Alfred Tarski, and Czesław Lejewski – prominent members of the Lvov-Warsaw School (LWS). We see our work in the tradition of the research of Leśniewski and Tarski. Building on the technical tools developed in this environment and in the spirit of the traditional research of the LWS, we engage here, in particular, with two classic works by Russell on fundamental ontology.

In the tradition of quantified modal logic, it was assumed that significantly different linguistic systems underlie reference to individuals, to times and to 'possible worlds'. Various results from recent research in formal semantics suggest that this is not so, and that there is in fact a pervasive symmetry between the linguistic means with which we refer to these three domains. Reference to individuals, times and worlds is uniformly effected through generalized quantifiers, definite descriptions, and pronouns, and in each domain grammatical (...) features situate the reference of terms as near, far or 'further' from the actual or from a reported speech act. We outline various directions in which a program of ontological symmetry could be developed, and we offer in the Appendix a symmetric fragment developed in a logic that can be seen as a compromise between an extensional and an intensional system.

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.
