<p>From the reviews:</p><p>"I welcome this book and its attempt to bring systematic, reductive, and semantical order to a field that has had many different approaches, written by two well-established researchers in this area and other related areas of technical work on philosophically and epistemically motivated logics." <i>Saul Kripke (The City University of New York)</i></p><p>“This book covers a broad range of ideas related to nonmonotonic reasoning. This review summarizes some of its nice ideas--or, as the authors say, its ‘logical tools.’ … It would be fair to call this whole book an exposition on reactive diagrams in various application areas. … there is substantial material for researchers. … the book is primarily concerned with semantic structures.” (K. Lodaya, ACM Computing Reviews, February, 2011)</p><p>“The book gives a very solid and comprehensive overview of various logics. It focuses on mapping of the logics to the formalism of reactive diagrams. … The book is especially suited for logicians and researchers seeking to establish a rigorous theoretical foundation for their reasoning systems, or who are interested in comparing different reasoning systems on the basis of a common ground.” (Jana Köhler, Zentralblatt MATH, Vol. 1215, 2011)</p>
