This book is the first in the field§of paraconsistency to offer a comprehensive overview of the subject, including§connections to other logics and applications in information processing,§linguistics, reasoning and argumentation, and philosophy of science. It is recommended§reading for anyone interested in the question of reasoning and§argumentation in the presence of contradictions, in semantics, in the paradoxes§of set theory and in the puzzling properties of negation in logic programming. Paraconsistent§logic comprises a major logical theory and offers the broadest possible perspective§on the debate of negation in logic and philosophy. It is a powerful tool for§reasoning under contradictoriness as it investigates logic systems in which§contradictory information does not lead to arbitrary conclusions. Reasoning§under contradictions constitutes one of most important and creative§achievements in contemporary logic, with deep roots in philosophical questions§involving negation and consistency§§This book offers an invaluable§introduction to a topic of central importance in logic and philosophy. It§discusses (i) the history of paraconsistent logic; (ii) language, negation, contradiction,§consistency and inconsistency; (iii) logics of formal inconsistency (LFIs)§and the main paraconsistent propositional systems; (iv) many-valued§companions, possible-translations semantics and non-deterministic semantics;§(v) paraconsistent modal logics; (vi) first-order paraconsistent logics; (vii)§applications to information processing, databases and quantum computation;§and (viii) applications to deontic paradoxes, connections to Eastern thought§and to dialogical reasoning.§§
