Publisher’s Note:

This book is a consideration of Hegel’s view on logic and basic logical concepts such as truth, form, validity, and contradiction, and aims to assess this view’s relevance for contemporary philosophical logic. The literature on Hegel’s logic is fairly rich. The attention to contemporary philosophical logic places the present research closer to those works interested in the link between Hegel’s thought and analytical philosophy, Koch 2014, Brandom 2014, 1-15, Pippin 2016, Moyar 2017, Quante & Mooren 2018 among others). In this context, one particularity of this book consists in focusing on something that has been generally underrated in the literature: the idea that, for Hegel as well as for Aristotle and many other authors, logic is the study of the forms of truth, i.e. the forms that our thought can assume in searching for truth. In this light, Hegel’s thinking about logic is a fundamental reference point for anyone interested in a philosophical foundation of logic.

Comment: The book could be used in any course on Hegel's logic, either as a main textbook (if focusing on the author's overall interpretation) or as further reading. The latter approach is facilitated by the structure of the book, since each part is focused on a distinct logical notion (logic, logical form, truth, validity, contradiction). Given the author's thesis that Hegel can be considered as a genuine interlocutor of philosophical logic as it is understood today, one might even try discussing some chapters in a course focusing on a particular logical notion.

Rahman, Shahid, Carnielli, Walter. The Dialogical Approach to Paraconsistency

Abstract:

Being a pragmatic and not a referential approach to semantics, the dialogical formulation of paraconsistency allows the following semantic idea to be expressed within a semi-formal system: In an argumentation it sometimes makes sense to distinguish between the contradiction of one of the argumentation partners with himself (internal contradiction) and the contradiction between the partners (external contradiction). The idea is that external contradiction may involve different semantic contexts in which, say A and not A have been asserted. The dialogical approach suggests a way of studying the dynamic process of contradictions through which the two contexts evolve for the sake of argumentation into one system containing both contexts. More technically, we show a new, dialogical, way to build paraconsistent systems for propositional and first-order logic with classical and intuitionistic features (i.e. paraconsistency both with and without tertium non-datur) and present their corresponding tableaux.

Comment: This paper would fit well in a course on dialogical formulations of logic (as either main or further reading, depending on the time dedicated to Lorenz-style approaches), or in a course on paraconsistent logic (as an alternative way of thinking about paraconsistency); both topics are introduced in an accessible enough way. If students have no familiarity with tableaux systems, sections 4 and 5.2 can be skipped.
