This book presents adaptive logics as an intuitive and powerful framework for modeling defeasible reasoning. It examines various contexts in which defeasible reasoning is useful and offers a compact introduction into adaptive logics.

The author first familiarizes readers with defeasible reasoning, the adaptive logics framework, combinations of adaptive logics, and a range of useful meta-theoretic properties. He then offers a systematic study of adaptive logics based on various applications.

The book presents formal models for defeasible reasoning stemming from different contexts, such as default reasoning, argumentation, and normative reasoning. It highlights various meta-theoretic advantages of adaptive logics over other logics or logical frameworks that model defeasible reasoning. In this way the book substantiates the status of adaptive logics as a generic formal framework for defeasible reasoning.

Christian Straßer obtained his PhD at the Centre for Logic and Philosophy of Science at Ghent University. His main research activities concern defeasible and normative reasoning. Having a background in both philosophy and computer science, he is interested in normative accounts of human reasoning as well as artificial intelligence. http://ugent.academia.edu/ChristianStraßer
