Eli Hirsch has contributed steadily to metaphysics since his ground-breaking (and much cited) work on identity through time (culminating in the 1982 OUP book The Concept of Identity). Within the last 10 years, his work on realism and quantifier variance has been front-and-center in the minds of many metaphysicians. Metametaphysics, which looks at foundational questions about the very practice of metaphysics and the questions it raises, is now a popular area of discussion. There is a lot of anxiety about what ontology is, and Hirsch's diagnosis of how revisionary ontologists go wrong is one of the main views being discussed. This volume collects HIrsch's essays from the last decade (with the exception of one article from 1978) on ontology and metametaphysics which are very much tied to these debates. His essays develop a distinctive language-based argument against various anti-commonsensical views that have recently dominated ontology. All these views go astray, Hirsch says, by failing to interpret ordinary assertions about existence in a plausibly charitable way, so their philosophizing leads them to misuse language about ontology -- our ordinary concept of 'what exists' -- in favor of a position othat is quite different. Hirsch will supply a new introduction. The volume will interest philosophers of metaphysics currently engaged in these debates.

Theodore Sider presents a broad new vision of metaphysics centred on the idea of structure. To describe the world well we must use concepts that 'carve at the joints', so that conceptual structure matches reality's structure. This approach illuminates a wide range of topics, such as time, modality, ontology, and the status of metaphysics itself.

This volume aims to develop the easy approach to ontology, showing how it leads to both a first-order simple realism about the disputed entities and a form of metaontological deflationism that takes ontological disputes themselves to be misguided, since existence questions may be answered by straightforward conceptual and/or empirical work. It also aims to defend the easy approach against a range of objections and to show it to be a viable and attractive alternative to hard ontology.

Rudolf Carnap's deflationary approach to ontology is once again attracting considerable interest and support. 11 original essays by leading voices in metametaphysics deepen our understanding of Carnap's contributions to metaontology, and explore how his legacy can be mined for insights into the contemporary debate.

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.

In Taking Morality Seriously: A Defense of Robust Realism David Enoch develops, argues for, and defends a strongly realist and objectivist view of ethics and normativity more broadly. This view—according to which there are perfectly objective, universal, moral and other normative truths that are not in any way reducible to other, natural truths—is familiar, but this book is the first in-detail development of the positive motivations for the view into reasonably precise arguments. And when the book turns defensive—defending Robust Realism against traditional objections—it mobilizes the original positive arguments for the view to help with fending off the objections. The main underlying motivation for Robust Realism developed in the book is that no other metaethical view can vindicate our taking morality seriously. The positive arguments developed here—the argument from the deliberative indispensability of normative truths, and the argument from the moral implications of metaethical objectivity (or its absence)—are thus arguments for Robust Realism that are sensitive to the underlying, pre-theoretical motivations for the view.
