Ontology is the philosophical discipline which aims to understand how things in the world are divided into categories and how these categories are related together. This is exactly what information scientists aim for in creating structured, automated representations, called ‘ontologies,’ for managing information in fields such as science, government, industry, and healthcare. Currently, these systems are designed in a variety of different ways, so they cannot share data with one another. They are often idiosyncratically structured, accessible only to those who created them, and unable to serve as inputs for automated reasoning. This volume shows, in a non-technical way and using examples from medicine and biology, how the rigorous application of theories and insights from philosophical ontology can improve the ontologies upon which information management depends.

An introduction to the field of applied ontology with examples derived particularly from biomedicine, covering theoretical components, design practices, and practical applications. 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.

This volume presents thirteen original essays which explore both traditional and contemporary aspects of the metaphysics of relations. It is uncontroversial that there are true relational predications-'Abelard loves Eloise', 'Simmias is taller than Socrates', 'smoking causes cancer', and so forth. More controversial is whether any true relational predications have irreducibly relational truthmakers. Do any of the statements above involve their subjects jointly instantiating polyadic properties, or can we explain their truths solely in terms of monadic, non-relational properties of the relata? According to a tradition dating back to Plato and Aristotle, and continued by medieval philosophers, polyadic properties are metaphysically dubious. In non-symmetric relations such as the amatory relation, a property would have to inhere in two things at once-lover and beloved-but characterise each differently, and this puzzled the ancients. More recent work on non-symmetric relations highlights difficulties with their directionality. Such problems offer clear motivation for attempting to reduce relations to monadic properties. By contrast, ontic structural realists hold that the nature of physical reality is exhausted by the relational structure expressed in the equations of fundamental physics. On this view, there must be some irreducible relations, for its fundamental ontology is purely relational. The Metaphysics of Relations draws together the work of a team of leading metaphysicians, to address topics as diverse as ancient and medieval reasons for scepticism about polyadic properties; recent attempts to reduce causal and spatiotemporal relations; recent work on the directionality of relational properties; powers ontologies and their associated problems; whether the most promising interpretations of quantum mechanics posit a fundamentally relational world; and whether the very idea of such a world is coherent. From those who question whether there are relational properties at all, to those who hold they are a fundamental part of reality, this book covers a broad spectrum of positions on the nature and ontological status of relations, from antiquity to the present day.

In this original work of philosophy, Andrew Benjamin calls for a new understanding of relationality, one inaugurating a philosophical mode of thought that takes relations among people and events as primary, over and above conceptions of simple particularity or abstraction. Drawing on the work of Descartes, Kant, Fichte, Hegel, and Heidegger, Benjamin shows that a relational ontology has always been at work within the history of philosophy even though philosophy has been reluctant to affirm its presence. Arguing for what he calls anoriginal relationality, he demonstrates that the already present status of a relational ontology is philosophy's other possibility. Touching on a range of topics including community, human-animal relations, and intimacy, Benjamin's thoughtful and penetrating distillation of ancient, modern, and twentieth-century philosophical ideas, and his judicious attention to art and literature make this book a model for original philosophical thinking and writing.

In Ontology and Closeness in Human-Nature Relationships, Neil H. Kessler identifies the preconceptions which can keep the modern human mind in the dark about what is happening relationally between humans and the more-than-human world. He has written an accessible work of environmental philosophy, with a focus on the ontology of human-nature relationships. In it, he contends that large-scale environmental problems are intimate and relational in origin. He also challenges the deeply embedded, modernist assumptions about the relational limitations of more-than-human beings, ones which place erroneous limitations on the possibilities for human/more-than-human closeness. Diverging from the posthumanist literature and its frequent reliance on new materialist ontology, the arguments in the book attempt to sweep away what ecofeminists call “human/nature dualisms. In doing so, conceptual avenues open up that have the power to radically alter how we engage in our daily interactions with the more-than-human world all around us. Given the diversity of fields and disciplines focused on the human-nature relationship, the topics of this book vary quite broadly, but always converge at the nexus of what is possible between humans and more-than-human beings. The discussion interweaves the influence of human/nature dualisms with the limitations of Deleuzian becoming and posthumanism’s new materialism and agential realism. It leverages interhuman interdependence theory, Charles Peirce’s synechism of feeling and various treatments of Theory of Mind while exploring the influence of human/nature dualisms on sustainability, place attachment, common worlds pedagogy, emergence, and critical animal studies. It also explores the implications of plant electrical activity, plant intelligence, and plant “neurobiology” for possibilities of relational capacities in plants while even grappling with theories of animism to challenge the animate/inanimate divide. The result is an engaging, novel treatment of human-nature relational ontology that will encourage the reader to look at the world in a whole new way.

The present edited collection is a fresh contribution to the international debate. Leading scholars from all over the world address the topic from different viewpoints: history of philosophy, ontology, philosophy of religion, and history of religious doctrines.

This book provides an exhaustive overview of the ontology of relations. Moreover, it offers a detailed defense of the existence of irreducible relations in the universe and shows that entities such as powers should be better thought of as relations. At first, the author discusses many classical arguments for and against the existence of relations and draws preliminary distinctions between internal and external relations and symmetrical and non-symmetrical relations. He defends the existence of irreducible relations against several objections, most notably three Bradleyan regresses. In response to these objections, the author argues that both internal and external relations should be thought of as relational modes and that intentional, temporal and spatial relations are external. He also presents several problems that are typically taken to affect non-symmetrical relations and introduces one new version of a theory to deal with them—the O-Roles theory. Finally, the author explores essential dependence relations and causal dependence relations and defends the view that powers are relational modes. The Ontology of Relations will be of interest to scholars and advanced students working in metaphysics, philosophy of science, and history of philosophy.
