This wide-ranging collection of essays explores the nature of logic and the key issues and debates in the metaphysics of logic.

Logic for Philosophy is an introduction to logic for students of contemporary philosophy. It is suitable both for advanced undergraduates and for beginning graduate students in philosophy. It covers (i) basic approaches to logic, including proof theory and especially model theory, (ii) extensions of standard logic that are important in philosophy, and (iii) some elementary philosophy of logic. It emphasizes breadth rather than depth. For example, it discusses modal logic and counterfactuals, but does not prove the central metalogical results for predicate logic (completeness, undecidability, etc.) Its goal is to introduce students to the logic they need to know in order to read contemporary philosophical work. It is very user-friendly for students without an extensive background in mathematics. In short, this book gives you the understanding of logic that you need to do philosophy.

With his customary incisiveness, W. V. Quine presents logic as the product of two factors, truth and grammar--but argues against the doctrine that the logical truths are true because of grammar or language. Rather, in presenting a general theory of grammar and discussing the boundaries and possible extensions of logic, Quine argues that logic is not a mere matter of words.

Offering a full-scale study of the theory of reality hidden beneath modern logic, The Metaphysical Foundations of Logic, a lecture course given in 1928, illuminates the transitional phase in Heidegger's thought from the existential analysis of Being and Time to the overcoming of metaphysics in his later philosophy. In a searching exposition of the metaphysical problems underpinning Leibniz's theory of logical judgment, Heidegger establishes that a given theory of logic is rooted in a certain conception of Being. He explores the significance of Western logic as a system-building technical tool and as a cultural phenomenon that is centuries old.

This performance of the Richard Strauss opera Arabella with the Orchestra of the Vienna State Opera features vocalists such as Emily Magee, Genia Kuhmeier, and Tomasz Konieczny in the leading roles. ~ Cammila Collar, Rovi

Timothy Williamson gives an original and provocative treatment of deep metaphysical questions about existence, contingency, and change, using the latest resources of quantified modal logic. Contrary to the widespread assumption that logic and metaphysics are disjoint, he argues that modal logic provides a structural core for metaphysics.

Philosophy of logic is a fundamental part of philosophical study, and one which is increasingly recognized as being immensely important in relation to many issues in metaphysics, metametaphysics, epistemology, philosophy of mathematics, and philosophy of language. This textbook provides a comprehensive and accessible introduction to topics including the objectivity of logical inference rules and its relevance in discussions of epistemological relativism, the revived interest in logical pluralism, the question of logic's metaphysical neutrality, and the demarcation between logic and mathematics. Chapters in the book cover the state of the art in contemporary philosophy of logic, and allow students to understand the philosophical relevance of these debates without having to contend with complex technical arguments. This will be a major new resource for students working on logic, as well as for readers seeking a better understanding of philosophy of logic in its wider context.

The papers presented in this volume examine topics of central interest in contemporary philosophy of logic. They include reflections on the nature of logic and its relevance for philosophy today, and explore in depth developments in informal logic and the relation of informal to symbolic logic, mathematical metatheory and the limiting metatheorems, modal logic, many-valued logic, relevance and paraconsistent logic, free logics, extensional v. intensional logics, the logic of fiction, epistemic logic, formal logical and semantic paradoxes, the concept of truth, the formal theory of entailment, objectual and substitutional interpretation of the quantifiers, infinity and domain constraints, the Löwenheim-Skolem theorem and Skolem paradox, vagueness, modal realism v. actualism, counterfactuals and the logic of causation, applications of logic and mathematics to the physical sciences, logically possible worlds and counterpart semantics, and the legacy of Hilbert's program and logicism. The handbook is meant to be both a compendium of new work in symbolic logic and an authoritative resource for students and researchers, a book to be consulted for specific information about recent developments in logic and to be read with pleasure for its technical acumen and philosophical insights.- Written by leading logicians and philosophers- Comprehensive authoritative coverage of all major areas of contemporary research in symbolic logic- Clear, in-depth expositions of technical detail- Progressive organization from general considerations to informal to symbolic logic to nonclassical logics- Presents current work in symbolic logic within a unified framework- Accessible to students, engaging for experts and professionals- Insightful philosophical discussions of all aspects of logic- Useful bibliographies in every chapter

Winner of the hegelpd–prize 2022 Contemporary philosophical discourse has deeply problematized the possibility of absolute existence. Hegel’s Foundation Free Metaphysics demonstrates that by reading Hegel’s Doctrine of the Concept in his Science of Logic as a form of Absolute Dialetheism, Hegel’s logic of the concept can account for the possibility of absolute existence. Through a close examination of Hegel’s concept of self-referential universality in his Science of Logic, Moss demonstrates how Hegel’s concept of singularity is designed to solve a host of metaphysical and epistemic paradoxes central to this problematic. He illustrates how Hegel’s revolutionary account of universality, particularity, and singularity offers solutions to six problems that have plagued the history of Western philosophy: the problem of nihilism, the problem of instantiation, the problem of the missing difference, the problem of absolute empiricism, the problem of onto-theology, and the third man regress. Moss shows that Hegel’s affirmation and development of a revised ontological argument for God’s existence is designed to establish the necessity of absolute existence. By adopting a metaphysical reading of Richard Dien Winfield’s foundation free epistemology, Moss critically engages dominant readings and contemporary debates in Hegel scholarship. Hegel’s Foundation Free Metaphysics will appeal to scholars interested in Hegel, German Idealism, 19th- and 20th-century European philosophy, metaphysics, epistemology, and contemporary European thought.
