This book explores the relationship between Hegel’s dialectics and formal logic. It examines the concept of dialectics, its meaning, and its use in contemporary thought. The volume opens the “old” debate about the formalization of Hegel’s dialectics and is motivated by the idea that asking about the connection between Hegel’s dialectics and formal logic is still relevant, for various reasons: Firstly, a new Hegel is circulating nowadays in the philosophical literature, with specific reference to Hegel’s dialectical logic and its relation to the history and philosophy of logic. Secondly, new research about the connection between contradictory logical systems and Hegel's dialectics is also being developed. Finally, there have been recent confirmations that the concept of dialectics is of general interest, and that the usual perplexities about the Hegelian triadic and fairly mechanic device of ‘yes, not, and not not’ are in remission. The chapters feature philosophically and historically motivated presentations of formal features of Hegel’s dialectics, critical considerations about the very idea of ‘formalizing dialectics’ and presentations of past attempts to formalize Hegel’s dialectics. The Formalization of Dialectics will be a key resource for scholars and researchers of the history and philosophy of logic and Hegel’s dialectics. It will also be of interest to anyone who wants to know more about the concept of dialectics, its meaning and its use in contemporary thought. This book was originally published as a special issue of History and Philosophy of Logic.

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 (Stekeler-Weithofer 1992 and 2019, Berto 2005, Rockmore 2005, Redding 2007, Nuzzo 2010 (ed.), 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 (including Frege), logic is the study of the forms of truth, i.e. the forms that our thought can (or ought to) 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.

The papers in this volume present some of the most recent results of the work about contradictions in philosophical logic and metaphysics; examine the history of contradiction in crucial phases of philosophical thought; consider the relevance of contradictions for political and philosophical actuality. From this consideration a common question emerges: the question of the irreducibility, reality and productive force of (some) contradictions.
