The Inconsistency of Certain Formal Logics.

The Journal of Symbolic Logic, 1942
A proof that certain systems of formal logic are inconsistent, in the sense that every formula expressible in them is provable, was published by Kleene and Rosser under the above title in 1935. For the case where the underlying system satisfies an additional condition—viz.

A Basic Logic of Formal Inconsistency: mbC

2016
This chapter begins a formal study of Logics of Formal Inconsistency (LFIs) by offering a careful survey of the basic logic of formal inconsistency, mbC. The chapter also lays out the main notation, ongoing definitions and main ideas that will be used throughout the book.

ON THE WAY TO A WIDER MODEL THEORY: COMPLETENESS THEOREMS FOR FIRST-ORDER LOGICS OF FORMAL INCONSISTENCY

The Review of Symbolic Logic, 2014
AbstractThis paper investigates the question of characterizing first-orderLFIs (logics of formal inconsistency) by means of two-valued semantics.LFIs are powerful paraconsistent logics that encode classical logic and permit a finer distinction between contradictions and inconsistencies, with a deep involvement in philosophical and foundational ...

On the Philosophy and Mathematics of the Logics of Formal Inconsistency

2015
The aim of this text is to present the philosophical motivations for the Logics of Formal Inconsistency (LFIs), along with some relevant technical results. The text is divided into two main parts (besides a short introduction). In Sect. 3.2, we present and discuss philosophical issues related to paraconsistency in general, and especially to logics of ...

Hallden's Logic of Nonsense and Its Expansions in View of Logics of Formal Inconsistency

2016 27th International Workshop on Database and Expert Systems Applications (DEXA), 2016
The paper explores the connection between Soren Hallden's logic of nonsense (and its expansions) and Logics of Formal Inconsistency (LFIs), one of the main traditions in paraconsistency. Although not much attention has been payed by paraconsistentists, Hallden's logic can be nicely connected to LFIs.
