This book gathers together thirteen of Peter van Inwagen's essays on metaphysics, several of which have acquired the status of modern classics in their field. They range widely across such topics as Quine's philosophy of quantification, the ontology of fiction, the part-whole relation, the theory of 'temporal parts', and human knowledge of modal truths. In addition, van Inwagen considers the question as to whether the psychological continuity theory of personal identity is compatible with materialism, and defends the thesis that possible states of affairs are abstract objects, in opposition to David Lewis's 'extreme modal realism'. A specially-written introduction completes the collection, which will be an invaluable resource for anyone interested in metaphysics.

The papers in this volume address fundamental, and interrelated, philosophical issues concerning modality and identity, issues that have not only been pivotal to the development of analytic philosophy in the twentieth century, but remain a key focus of metaphysical debate in the twenty-first. How are we to understand the concepts of necessity and possibility? Is chance a basic ingredient of reality? How are we to make sense of claims about personal identity? Do numbers requiredistinctive identity criteria? Does the capacity to identify an object presuppose an ability to bring it under a sortal concept?Rather than presenting a single, partisan perspective, Identity and Modality enriches our understanding of identity and modality by bringing together papers written by leading researchers working in metaphysics, the philosophy of mind, the philosophy of science, and the philosophy of mathematics. The resulting variety of perspectives correspondingly reflects both the breadth and depth of contemporary theorizing about identity and modality, each paper addressing a particular issue andadvancing our knowledge of the area.This volume will provide essential reading for graduate students in the subject and professional philosophers.

This is a book about the concept of a physical thing and about how the names of things relate to the things they name. It questions the prevalent view that names 'refer to' or 'denote' the things they name. Instead it presents a new theory of proper names, according to which names express certain special properties that the things they name exhibit. This theory leads to some important conclusions about whether things have any of their properties as a matter of necessity. This will be an important book for philosophers in metaphysics and the philosophy of language, though it will also interest linguists concerned with the semantics of natural language.

This book explores a range of traditional and contemporary metaphysical themes that figure in the writings of E. J. Lowe, whose powerful and influential work was still developing at the time of his death in 2015. During his forty-year career, he established himself as one of the world's leading philosophers, publishing eleven single-authored books and well over two hundred essays. His scholarship was strikingly broad, ranging from early modern philosophy to the interpretation of quantum mechanics. His most important and sustained contributions were to philosophy of mind, philosophical logic, and above all metaphysics. E. J. Lowe was committed to a systematic, realist, and scientifically informed neo-Aristotelean approach to philosophy. This volume presents a set of new essays by philosophers who share this commitment, addressing interrelated themes of his work. In particular, these papers focus upon three closely connected topics central not only to Lowe's work, but to contemporary metaphysics and philosophy of mind in general: ontology and categories of being; essence and modality, and the metaphysics of mental causation.

Bob Hale presents a broadly Fregean approach to metaphysics, according to which ontology and modality are mutually dependent upon one another. He argues that facts about what kinds of things exist depend on facts about what is possible. Modal facts are fundamental, and have their basis in the essences of things—not in meanings or concepts.

This is a collection of Peter van Inwagen's recent essays on ontology and meta-ontology.

Ontology and Metaontology: A Contemporary Guide is a clear and accessible survey of ontology, focusing on the most recent trends in the discipline. Divided into parts, the first half characterizes metaontology: the discourse on the methodology of ontological inquiry, covering the main concepts, tools, and methods of the discipline, exploring the notions of being and existence, ontological commitment, paraphrase strategies, fictionalist strategies, and other metaontological questions. The second half considers a series of case studies, introducing and familiarizing the reader with concrete examples of the latest research in the field. The basic sub-fields of ontology are covered here via an accessible and captivating exposition: events, properties, universals, abstract objects, possible worlds, material beings, mereology, fictional objects. The guide's modular structure allows for a flexible approach to the subject, making it suitable for both undergraduates and postgraduates looking to better understand and apply the exciting developments and debates taking place in ontology today.
