Towards Non Being

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.

Nonexistence is ubiquitous, yet mysterious. This volume explores some of the most puzzling questions about non-being and nonexistence, and offers answers from diverse philosophical perspectives. The contributors draw on analytic, continental, Buddhist, and Jewish philosophical traditions, and the topics range from metaphysics to ethics, from philosophy of science to philosophy of language, and beyond.

This revised and considerably expanded 2nd edition brings together a wide range of topics, including modal, tense, conditional, intuitionist, many-valued, paraconsistent, relevant, and fuzzy logics. Part 1, on propositional logic, is the old Introduction, but contains much new material. Part 2 is entirely new, and covers quantification and identity for all the logics in Part 1. The material is unified by the underlying theme of world semantics. All of the topics are explained clearly using devices such as tableau proofs, and their relation to current philosophical issues and debates are discussed. Students with a basic understanding of classical logic will find this book an invaluable introduction to an area that has become of central importance in both logic and philosophy. It will also interest people working in mathematics and computer science who wish to know about the area.

This work is a substantial contribution to the history of philosophy. Its subject, the ninth-century philosopher John Scottus Eriugena, developed a form of idealism that owed as much to the Greek Neoplatonic tradition as to the Latin fathers and anticipated the priority of the subject in its modern, most radical statement: German idealism. Moran has written the most comprehensive study yet of Eriugena's philosophy, tracing the sources of his thinking and analyzing his most important text, the Periphyseon. This volume will be of special interest to historians of mediaeval philosophy, history, and theology.

How Non-being Haunts Being reveals how the human world is not reducible to “what is.” Human life is an open expanse of “what was” and “what will be,” “what might be” and “what should be.” It is a world of desires, dreams, fictions, historical figures, planned events, spatial and temporal distances, in a word, absent presences and present absences. Corey Anton draws upon and integrates thinkers such as Jean-Paul Sartre, Henri Bergson, Kenneth Burke, Terrence Deacon, Lynn Margulis, R. D. Laing, Gregory Bateson, Douglas Harding, and E. M. Cioran. He discloses the moral possibilities liberated through death acceptance by showing how living beings, who are of space not merely in it, are fundamentally on loan to themselves. A heady multidisciplinary work, How Non-being Haunts Being explores how absence, incompleteness, and negation saturate life, language, thought, and culture. It details how meaning and moral agency depend upon forms of non-being, and it argues that death acceptance in no way inevitably slides into nihilism. Thoroughgoing death acceptance, in fact, opens opportunities for deeper levels of self-understanding and for greater compassion regarding our common fate. Sure to provoke thought and to stimulate much conversation, it offers countless insights into the human condition.

Logic is often perceived as having little to do with the rest of philosophy, and even less to do with real life. Graham Priest explores the philosophical roots of the subject, explaining how modern formal logic addresses many issues.
