This leads to a precise characterization of ideal propositional paraconsistent logics. We show that every three-valued paraconsistent logic which is contained in classical logic, and has a proper implication connective, is ideal In logica, per logica paraconsistente si intende un sistema formale in cui possono verificarsi in modo controllato delle eccezioni al principio di non contraddizione, cioè possono presentarsi delle contraddizioni, senza però che con questo sia possibile derivare nel sistema ogni proposizione, evitando quindi il principio di esplosione . 2002] in this Handbook was dedicated to paraconsistent logics. Although partaking in the same basic views on paraconsistency, our approach is ori-ented towards investigating and exhibiting the features of an ample and very expressive class of paraconsistent logics |the above mentioned LFIs. Paraconsistent logic makes it possible to study inconsistent theories in a coherent way. From its modern start in the mid-20th century, paraconsistency was intended for use in mathematics, providing a rigorous framework for describing abstract objects and structures where some contradictions are allowed, without collapse into incoherence. Another view in paraconsistency, that we call metaphysical neutrality, 'suspends judgement' with respect to the nature of contradictions. It is a somewhat pragmatic position: the fact that contradictions occur in several contexts of reasoning is enough to justify a non-explosive account of logical consequence, and there is no need to go into the metaphysical question about the nature of 12.

Word puzzles and the problem of their representations in logic languages have received considerable attention in the last decade (Ponnuru Handbook of Paraconsistency (Studies in Logic). College Publications, The paraconsistent conditional logic is axiomatized by a sequent system mathcal {C} which is an extension of the Belnap-Dunn four-valued logic with a conditional operator. Some acceptive extensions of mathcal {C} are shown to be sound and complete. We also show the finite acceptive model property and decidability of these logics.
