Initially proposed as rivals of classical logic, alternative logics have become increasingly important in areas such as computer science and artificial intelligence. Fuzzy logic, in particular, has motivated major technological developments in recent years.

Susan Haack's Deviant Logic provided the first extended examination of the philosophical consequences of alternative logics. In this new volume, Haack includes the complete text of Deviant Logic, as well as five additional papers that expand and update it. Two of these essays critique fuzzy logic, while three augment Deviant Logic's treatment of deduction and logical truth. Haack also provides an extensive new foreword, brief introductions to the new essays, and an updated bibliography of recent work in these areas.

Deviant Logic, Fuzzy Logic will be indispensable to students of philosophy, philosophy of science, linguistics, mathematics, and computer science, and will also prove invaluable to experienced scholars working in these fields.

Susan Haack is professor of philosophy at the University of Miami. She is the author of Philosophy of Logics and Evidence and Inquiry: Towards Reconstruction in Epistemology.

Editorial Reviews

Library Journal
The success of fuzzy logic in certain technological applications such as in controllers for air-conditioners and other appliances, in subway braking systems, and so forth, has led some philosophers to see it as a rival to classical logic. This book is an extended defense of classical logic against attacks by proponents not only of fuzzy logic but also of many-valued, dialethic, intuitionist, and other "alternative" logics. Haack philosophy, Univ. of Miami deals here not only with logic but also with important issues in epistemology; however, the level of discourse is such that its main audience will be logicians and serious students of philosophy. The book contains the complete text of Haack's 1974 publication, Deviant Logic, and five other essays that have also appeared before. In view of this, academic libraries need consider only as budgets allow.Leon H. Brody, U.S. Office of Personnel Mgt. Lib., Washingon, D.C.
