Adaptive Logics 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

"This is a book on the application of a class of logics, called adaptive logics, to a particular form of reasoning, in effect, of a defeasible kind. ... this book is clearly aimed at people interested in knowing the reaches of a formal logic formalism, from a philosophical viewpoint, without great concern for complexity and computational issues. And it may also serve a public with such computational concerns looking for an articulated starting point." (Marcelo Finger, Mathematical Reviews, April, 2016)
