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

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.

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.

Towards Non-Being presents an account of the semantics of intentional language - verbs such as 'believes', 'fears', 'seeks', 'imagines'. Graham Priest's account tackles problems concerning intentional states which are often brushed under the carpet in discussions of intentionality, such as their failure to be closed under deducibility. Drawing on the work of the late Richard Routley (Sylvan), it proceeds in terms of objects that may be either existent or non-existent, atworlds that may be either possible or impossible. Since Russell, non-existent objects have had a bad press in Western philosophy; Priest mounts a full-scale defence. In the process, he offers an account of both fictional and mathematical objects as non-existent.The book will be of central interest to anyone who is concerned with intentionality in the philosophy of mind or philosophy of language, the metaphysics of existence and identity, the philosophy or fiction, the philosophy of mathematics, or cognitive representation in AI.

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

Hegel frequently claimed that the heart of his entire system was a book widely regarded as among the most difficult in the history of philosophy, The Science of Logic. This is the book that presents his metaphysics, an enterprise that he insists can only be properly understood as a “logic,” or a “science of pure thinking.” Since he also wrote that the proper object of any such logic is pure thinking itself, it has always been unclear in just what sense such a science could be a “metaphysics.” Robert B. Pippin offers here a bold, original interpretation of Hegel’s claim that only now, after Kant’s critical breakthrough in philosophy, can we understand how logic can be a metaphysics. Pippin addresses Hegel’s deep, constant reliance on Aristotle’s conception of metaphysics, the difference between Hegel’s project and modern rationalist metaphysics, and the links between the “logic as metaphysics” claim and modern developments in the philosophy of logic. Pippin goes on to explore many other facets of Hegel’s thought, including the significance for a philosophical logic of the self-conscious character of thought, the dynamism of reason in Kant and Hegel, life as a logical category, and what Hegel might mean by the unity of the idea of the true and the idea of the good in the “Absolute Idea.” The culmination of Pippin’s work on Hegel and German idealism, this is a book that no Hegel scholar or historian of philosophy will want to miss.

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.
