Meta-Arguments in Heterogeneous Logics and How to Evaluate Them

Abstract This paper explores the problem of evaluating meta-arguments within the framework of heterogeneous logics. I introduce two new heterogeneous logics, KLP and LK3 , which are based on the interpreted languages of LP and K3 . I then present three distinct approaches to meta-argument evaluation, each aimed at preserving, in different ways, the heterogeneity of the underlying logics. Finally, I show that the second approach allows me to distinguish these new logics from others such as TS and ST , offering a more nuanced framework to address meta-argument distinctions in heterogeneous settings.
