Paraconsistent Logic in the Field of Classical Logic

TLDR: In this article, a da costa paraconsistent logic system is regarded as basis to analyse the logic connection between proposition A and negation of Paraconsistent Logic, and the difference between contradiction of Paraconistent, Law of contradiction and contradiction of classical logic,law of contradiction.

Abstract: In this article by the skill of N.C.A da costa paraconsistent logic system is regarded as basis to analyse the logic connection between proposition A and negation of paraconsistent logic A,difference between contradiction of paraconsistent,law of contradiction and contradiction of classical logic,law of contradiction.It points out that N.C.A da costa paraconsistent logic is not true meaning of paraconsistent logic.But N.C.A da costa paraconsistent logic is important in the theory of non-classical logic,as non-Eudidean geometry and Eudidean geometry.
