of Abstract Argumentation Guido Boella1 , Joris Hulstijn2 , and Leendert van der Torre3 1 Universit´a di Torino 2 Vrije Universiteit, Amsterdam 3 CWI Amsterdam and Delft University of Technology In this paper we introduce a logic of abstract argumentation capturing Dung’s theory of abstract argumentation, based on connectives for attack and deextend it to a modal logic of abstract argumentation to generalize Dung’s theory and define variants of it. Moreover, we use the logic to relate Dung’s theory of abstract argumentation to more traditional conditional and comparative formalisms, and we illustrate how to reason about arguments in meta-argumentation.
