Alltagslogik

This work aims to establish a comprehensive typology of schemes of everyday argumentation. In order to clarify the central notions of »logical validity« and »plausibility«, the author discusses various logical and linguistic approaches. Following Wittgenstein's »Usage Theory«, the authors concludes that the plausibility of everyday argumentation depends on the rules of use of (different subgroups of ) a speech community. This is empirically based on 300 passages from written and spoken everyday argumentation from various texts such as media discussions, newspaper commentaries, party propaganda and commercial texts.
