ETHIC ASPECTS OF ARGUMENTATION

Hans-hermann Hoppe’s Argumentation Ethic: a Critique

ONE OF THE MOST prominent theorists of anarcho-capitalism is HansHermann Hoppe. In what is perhaps his most famous result, the argumentation ethic for libertarianism, he purports to establish an a priori defense of the justice of a social order based exclusively on private property. Hoppe claims that all participants in a debate must presuppose the libertarian principle that every person owns h...

Computational Aspects of Abstract Argumentation

This work is in the context of formal argumentation, a sub-field of Artificial Intelligence. Probably the most popular formalism in argumentation is abstract argumentation as introduced by Dung [42]. So called abstract argumentation frameworks abstract from the actual content of arguments and represent them as abstract entities and further abstract from the reasons of conflicts between argument...

Two Aspects of Relevance in Structured Argumentation: Minimality and Paraconsistency

This paper studies two issues concerning relevance in structured argumentation in the context of the ASPIC framework, arising from the combined use of strict and defeasible inference rules. One issue arises if the strict inference rules correspond to classical logic. A longstanding problem is how the trivialising effect of the classical Ex Falso principle can be avoided while satisfying consist...

Computational Aspects of cf2 and stage2 Argumentation Semantics

We consider two instantiations of the SCC-recursive schema for argumentation semantics, cf2 , using maximal conflict-free sets as base semantics, and stage2 , using stage extensions as base semantics. Both of them have been shown to be in general of high complexity. We provide a detailed analysis of possible tractable fragments for these semantics. Moreover we present a labeling based algorithm...
